The idea solves an important problem of persons who strive to merge Christian values with the execution of leadership tasks. This vision is strongly interconnected with Catholic Social Teaching, which attempts to implement a Christian model of behaviour in each sphere of social life.
The aim of the article is to analyse the origins of the concept from the historical perspective and to present possible benefits and drawbacks of practicing this leadership model in the modern world. The analysis is founded on the grass-roots papers of the concept, and on contemporary publishing of the Church and academics in the sphere. This working time is often longer than the time they spend with their families or friends TEDx Talks, This simple example shows how important the role of a leader in each society is. Leading others is a key function in the proper fulfilment of other roles.
It explains the special attention paid by the Church and other social institutions to guiding leaders to perform their role properly. Nowadays, the Church emphasizes a lot of challenges which the leaders face in their job. Secondly, new technologies in the sphere of communication are overloading people with information and creating big obstacles in the way of clear decision-making. The next factor - financialization - makes firms insensitive to social problems, reorienting them to big profits at any cost.
The last problem is related to cultural transformations, with a tendency towards individualism, which make people insensitive to each other. The combined result of all these factors distracts us from treating the common good as the main goal of both leaders and workers Pontifical Council for Justice and Peace, , 2. Servant leadership is a concept which deals with all problems using a strategy based on the Christian model of life.
It introduces principles of human dignity, justice, subsidiarity in ruling others, and respect for each individual person Marek, , 1. It seems to be a great answer to current problems. The most fundamental source of the servant leadership concept comes from the Bible. Jesus Christ by His life and activities showed the core of the concept.
Jesus emphasizes humility and love among people.
The fact of devoting His life to ransoming the sins of humankind presents the greatest measure of serving others. This teaching is the most obvious way of proving that to serve is divine. A more academic approach to the concept was introduced by Robert K. Greenleaf in Greenleaf was an American essayist who wrote a few papers on the issue of servant leadership. The plot is built around a journey during which a servant Leo, who seemed to play no crucial role in the band of travellers, disappeared. The whole group then became completely disorganised, was in despair and the journey had to be abandoned.
Later on, a man from the band finds Leo in the Order which funded the journey. The man discovers that Leo is a leader and a spiritual master of the Order. Based on this story, R. Servant leaders consider the needs of other people in the first-place. The other extreme type of leadership introduced by R.
Greenleaf is the leader-first, who is a person of opposite interests to the principles of the servant-first Greenleaf, , 6, In academic circles, the servant leadership concept has drawn a lot of attention in recent years. Around papers have been published in the last two decades, with growing interest year by year. In the last four years, articles appeared, with a majority of an empirical nature. This means that the theory is becoming more and more practical.
A broad interest in the field of application of servant leadership principles caused a great number of leadership coaches interested in spreading the idea to appear. The most well-known activist in this sphere is John Maxwell. Maxwell has sold 26 million books in fifty languages. His foundation has trained about 6 million leaders from every country in the world Christ Fellowship Church, ; Maxwell, For more than 40 years J. Maxwell has been teaching how to be a truly servant leader. Finally, J. Maxwell says that nowadays a leadership model has been worked out which is the most effective regardless of the time and culture in which it is embedded.
The primary principle of the model is described by J. The author teaches leaders to apply the servant leadership in the simplest way. He tells them just to serve people, to add value to them and to enjoy their success. As a result, servant leaders gain the most loyal people around them. Before such conduct, when each employee knows that the leader is ready to devote him or herself to them, the worker will give all needed efforts to do the same.
Besides coaches and activists, servant leadership is presented by prominent CEOs as an effective remedy for companies. A board meeting was held to deal with the crisis. The board tried to figure out a new strategy to save the company. The key of the strategy was to dare to serve others. This group had not been paid sufficient attention before. They are the people who engage the most in establishing restaurants, caring about employees and are the front desk in front of customers. Afterwards, when the strategy had been implemented, an annual survey has been held to monitor if the franchisees are satisfied with the leadership model.
She presents three steps in the method. First, there should be a bold desire to dare to serve. Then, the leader should serve people and love them. The third step is delivering great company results as a shared result. The company grew and went international. The teaching of Jesus perfectly translates what servant leadership is about.
The concept is very demanding. It requires leaders to give themselves entirely to their employees. Such a leadership model leads organizations to great results, as has been proved in practice. It causes positive phenomena as:. Current tendencies of businesses show a positive attitude to the approach. Academic research is also very interested in servant leadership, and the Church as well promotes the concept. This coincidence proves the words of J. Maxwell, who underlines that this model of leadership is an outcome of long historical exploration to find the perfect model.
Servant leadership may in the future improve business performance, making leaders feel more comfortable in fulfilling their vocation, based on their own moral principles, to be authentic simultaneously in private and professional life and bring the common good into modern society.

The project designed an original course content classification method, with the objective of comparing and evaluating courses from different education systems, and created the first integrated Knowledge Base of the Catholic and Ecclesiastical Higher Education Institutions CHEI providing CST courses. This could be used, along with other inputs and sources, in developing programmes of various types, such as reinforcing social capital development or social inclusion. It is important as a source of values and orientation in countries that underwent decades of Communist rule and now struggle with the impact of Western liberalism.
It can be improved especially through greater collaboration and networking among existing institutions and experts within the region as a whole.

A first meeting held at the Angelicum in Rome on June In the same week, a summer school was organized with eight students selected from universities in Croatia, Czech Republic, Poland, Romania, Slovakia, Slovenia and Ukraine. They attended specific lessons on CST, participated in meetings and worked both together and alone to refine their project topics; finally they presented their work to the Expert Council members and shared with them ideas and proposals. Below are articles by four of the students. Although the Church has defined herself coherently, for at least two centuries, as only a spiritual and moral entity, it continues to be perceived by certain States as an unacceptable political actor.
Those States are not ready to recognize the autonomy of the Catholic Church, since, while the Church is universal, States have their constituencies within a specific nation. As far as the autonomy of the Papacy is concerned, a key question concerns the status of Catholic hierarchies in certain states. In the Western Hemisphere, between the end of the first Christian Millennium and the beginning of the second century of the new Millennium, the same matter poisoned the relationship between the Holy See and the Holy Roman Empire, that is, with Christian emperors and feudatories, through the so-called Investiture Controversy.
The Concordat of Worms, also known as the Pactum Calixtinum , was signed on 23 September , and deprived the Emperor of the right of investiture of bishops and other ecclesiastical figures with ring and crosier, that is, with the symbols of spiritual power. The clergy was declared free, and the properties of the Church inviolable. The Pope accepted that ecclesiastical elections in Germany would be witnessed by imperial envoys.
At the same time, the investiture with a scepter remained the prerogative of the emperor, as a sign that the estates of the Church were held under the crown. In Germany, feudal investiture came before episcopal investiture; in Italy and Burgundy the practice was the reverse, where the full jurisdiction of the Pope was restored.
As a result, the hierarchy faithful to Rome suffered repression and was often forced to operate undercover. During more than six long decades, Chinese Catholic believers, now 12 million, have carried the burden of this controversy. Nenni writes in his memoirs that he spoke 2 to Mao about the matter of the Catholic missions, receiving the following answer:. No measure has been taken or will be taken against the Catholic missions as such. There are missionaries who stood against the revolution and suffered the consequences. Coexistence is always possible.
They underlined that relations with the Holy See were unchanged with respect to the pre-revolutionary years. Afterwards Nenni took note of the synthetic and detailed account of the evolution of the Catholic Church during the Maoist regime, as offered by the State Authority for Religious Affairs. At the end he gives his own position:.
The government is able to guarantee the security of incoming new missionaries. Only one thing is requested: no conspiracy against the unity of the Chinese people, and respect for revolutionary laws 4. After the repression of the years , and the opening up of the Maoist regime in Hundred Flowers Campaign , which produced, inter alia, the liberation of Catholics previously arrested, the events of the Cultural Revolution raised tensions again between the regime and the Holy See.
After the Cultural Revolution, two positions emerged: on the one side, the militant atheism of the state had to become tolerant, coherent with the season of reforms opened up by Deng; on the other side, religions had to accept that the state considered the practice of religion to be a private affair which should not influence public life and the behavior of the state.
The dispute between the PRC and the Holy See could aim at a solution, if both positions could be harmonized. In this frame, historical figures such as the Jesuits Matteo Ricci and Michele Ruggieri at the end of s, and two and half centuries before, those of a number of Franciscan ambassadors like Giovanni da Pian del Carpine 5 , sent by Pope Innocent IV to the Mogul Grand Khan, show the Chinese that they may have good friends in the Catholic environment.
The acme of this behavior was in the s. At the beginning of the century, the Chinese civilization overwhelmed Western civilization, but the Ming dynasty shut all the ports and frontiers to the influence of foreigners. During the following century, those who built ships with more than two masts would suffer the death penalty.
As to your entreaty to send one of your nationals to be accredited to my Celestial Court and to be in control of your country's trade with China, this request is contrary to all usage of my dynasty and cannot possibly be entertained. It is true that Europeans, in the service of the dynasty, have been permitted to live at Peking, but they are compelled to adopt Chinese dress, they are strictly confined to their own precincts and are never permitted to return home. Patriotism is a shared sentiment in China, and any agreement between the State and the Holy See has to deal with this.
The cardinal of Hong Kong, John Tong 7 pointed out the loyalty of the Church to the state specifying that religious freedoms have nothing to do with separatism or claims to independence that are motivated by religious beliefs. The Holy See is accused by some believers of excessive realism in dealing with Beijing. Tong has written that the Roman Church is not a special case, and that the matter relates to freedom of religion and cult for everyone in China. Joseph Zen Ze-kiun, Bishop Emeritus of Hong Kong, is harshly against any bilateral agreement that, in his opinion, will inevitably undermine the moral authority of the Church, if signed before the restoration of full religious freedom in China.
Friendly fire comes especially from the Southern East Asian Churches, which has suffered long periods of repression and physical attack by Communist regimes. When conditions will exist for establishing diplomatic bilateral relations, the Vatican will break with Taiwan. Certain contradictions in Chinese government behavior are evident. A China Aid report shows that in , persecution against Christians was growing 8. In , the Chinese government campaigned against religious proselytism.
In doing so, the spread of Christianity was also attacked. Churches were demolished and Christian symbols cancelled. This happened in territories where the missionary spirit is particularly active 9. The information is confirmed by the agency Fides. The province of He Bei looks to be the most active, with about 12, baptized, while in Beijing, the newly baptized in that year were 1, The Pope is recognized as the head of China's Catholics: China will recommend Bishops before their appointment by the Pope, while the Pope is allowed to veto any Bishop proposed by China.
China will recognise soon a number of the forty or so underground bishops appointed by Rome. For the first time in about 70 years, all the Chinese bishops are in communion with Rome, even though not all of them are recognized and agreed upon.
It seems that the provisional agreement did not change certain Chinese habits. The spreading of this kind of information has reinforced the opponents to the provisional agreement between Rome and Beijing. It is evident that Zen was not convinced by the arguments of Msgr.
Tong in the quoted article. Tong has recalled that to choose the lesser of two evils is normal Christian ethical behavior. Criticism against the Vatican also comes from certain Protestant Churches that are connected with the religious American movements politically currently campaigning against China Years before, Canon had been the source of the excommunications of the hierarchy belonging to CCPA.
Nenni, Tempo di guerra fredda, diari , Sugar Co, , pp. There were also Catholics who accepted to cooperate with the regime. At the end of the century, Pope Nicholas IV sent another Franciscan to China, Giovanni da Montecorvino: he erected two churches in Beijing, baptized more than 2, Mogul and translated psalms and religious songs from the Old Testament into Chinese. Clement V nominated him as the Archbishop of Beijing. Another Franciscan to be remembered is Odoricus from Pordenone, author of a Latin chronicle about his year Chinese journey.
Details on the Franciscan Chinese missions can be found in M. Lo Russo, Il saio e la lince. Viaggio sentimentale nelle Umbrie dei miti, Rusconi, , pp. He would progressively be honored and respected. Another Jesuit missionary deserves attention, Prospero Intorcetta. A Sicilian, he arrived in China in He was the first to translate Confucius into Latin. See www. It proposed a list of 64 demolished churches with pictures. Asia News. During that meeting, the two representatives signed a Provisional Agreement on the appointment of Bishops. The above-mentioned Provisional Agreement, which is the fruit of a gradual and reciprocal rapprochement, has been agreed following a long process of careful negotiation and foresees the possibility of periodic reviews of its application.
It concerns the nomination of Bishops, a question of great importance for the life of the Church, and creates the conditions for greater collaboration at the bilateral level. The shared hope is that this agreement may favour a fruitful and forward-looking process of institutional dialogue and may contribute positively to the life of the Catholic Church in China, to the common good of the Chinese people and to peace in the world.
The first is the crescendo making clear the supposed antithesis U. One notably silent voice: the Vatican …. La reazione di netta chiusura nei confronti di questa visione, che viene percepita come un vero e proprio attentato alla proposta cristiana, ha provocato e non poteva che provocare un processo di privatizzazione della religione; processo peraltro auspicato e promosso dalla cultura dominante.

However, the lobbying success of these religious groups has rekindled, once again, the question of the role and position of religion in the American social and political square Martin Pew Research The United States is still mostly a Protestant country Protestants have historically tended to argue against the Catholic —or Thomistic— view, that the virtuous political life is simply a manifestation of inner virtue Goyette They have advocated the opinion that virtue and power should be dealt with separately Kainz The American project, mostly based on this Protestant ethos, prefers to support a minimalist vision of the State that would be strong enough, nonetheless, to protect minority groups from being persecuted, while confining faith to the internal forum.
This is basically enshrined in the First Amendment of the U. Constitution Hancock Thus, Evangelical Christianity in the U. But, beginning in the s with the rise of the Christian right which seeks "to apply their understanding of the teachings of Christianity to politics and to public policy by proclaiming the value of those teachings or by seeking to use those teachings to influence law and public policy," the pendulum swung towards a political Evangelical Christianity Andersen Nevertheless, since American Evangelicals have veered, once again, towards making a distinction between what is needed in the public forum and the ideals that should be upheld in private.
This has allowed them to support political candidates that were less than virtuous in the private sphere but who would advance their understanding of the teachings of Christianity in the public sphere Kimbrel The political platform of the Republican Party generally supports an economic and socially conservative ideology that seeks to uphold traditional values whereas the Democratic Party tends to support a modern liberalism that advocates social and economic equality, along with the Welfare State Sullivan Sinema just won in the mid-term elections in Arizona, where the Senate seat was vacated by Republican Jeff Flace "to become the first woman to win a U.

Moreover, most believe that religious institutions benefit society by strengthening community bonds and aiding the poor. Projected religious changes in the global population from to predict that Muslims will increase from 1.
Nonetheless, the religious composition of the United States is predicted to go from One of the main reasons for the decline of Christians and the growth of the Nones is so-called "generational replacement": The Millennial generation born between and "display much lower levels of religious affiliation, including less connection with Christian churches, than older generations" Cooperman The current American social and cultural context tends to cause "religious faith to atrophy among [believing] communities of all creeds, races, and national origin" Davis According to Psychology Professor Steven Reiss, "religion rises and falls in popularity depending on how well it satisfies our needs versus the secular alternatives" Reiss Psychologists W.
Keith Campbell and Jean Twenge cite a rise in narcissism and self-centeredness among the Millennial generations that might explain the four major shifts detected by Professor Reiss as possibly behind the decline in religious affiliation in the United States among Millennials Campbell and Twenge :. Organized religion versus spirituality , American Millennials prefer to search for a mystical, personal God that meets their individual needs. They feel that organized religion only gets in the way of true religious experience Reiss Tribalism versus humanitarianism , American Millennials live in a globally interconnected world.
As they experience the similarities of people everywhere, they tend to think of believers as alike, regardless of religious affiliation. Although this may drive their interest in interfaith activities, it lessens their need for loyalty to the moral code and religion of their ancestors "tribalism" Reiss Traditional versus non-traditional families , Fewer than half of American Millennials live in "traditional" families, that is, "in a home with two married heterosexual parents in their first marriage" Livingston Traditionally, organized religions have depended primarily on the family to rear religious children and recruit new church members.
Moreover, organized religion may hold beliefs that are less relevant to children growing up in non-traditional families versus traditional ones e. Trust versus loss of confidence in institutions , Trust in American institutions, outside of the military and small business, is below historical trends Jones Confidence in religious institutions is at an all-time low, especially due to sexual and financial scandals in Church organizations Saad This is mostly due to confidence in Pope Francis' leadership regarding these issues, although, after recent revelations of sex abuse scandals and coverup, particularly regarding ex-Cardinal Theodore McCarrick, U.
If these general social and political trends persist, the rising numbers of Nones will have a greater say in the shaping of a more secularized American experience and a further low-profile or private role for religion in U. Nonetheless, this does not necessarily mean it will be so. Religions have a great capacity to change and adapt, as they have done in the past, trying to better meet basic human needs. Furthermore, a U.

The purpose of the present paper is to provide a pilot comparative study of these two Argentinian markers in order to examine their free interchangeability and to refute it eventually. A commutation test has been used as a basic tool to compare the behavior and functions of che and boludo and the results have helped to reveal contexts in which it would be inadmissible or inappropriate to employ boludo instead of che due to the possible violation of politeness norms.
In the article, che and boludo are considered mainly from the sociolinguistic and pragmatic approaches although some important cultural phenomena are discussed as well.

Che a 1: recombinant expression, purification and correspondence to the natural form. Pollinosis to chenopods is one of the main causes of allergy in desertic regions and it is increasing in the South of Europe and Western USA. Che a 1 is a major allergen for chenopod-allergic subjects and belongs to the Ole-elike family of proteins. Pichia pastoris yeast has been used as expression system to produce the recombinant form of Che a 1 r Che a 1.
Molecular characterization was performed using Edman degradation, mass spectrometry and concanavalin A staining. Sera from patients allergic to chenopod pollen, as well as polyclonal and monoclonal antibodies raised against Ole e 1, were used in immunoblotting, ELISA and inhibition assays for immunological characterization of r Che a 1. N-terminal amino acid sequence of r Che a 1 and molecular mass were according to those of the protein isolated from chenopod pollen.

Dai ruoli professionali ai processi di cura, attraverso una lettura di "Quel che resta del giorno" di Kazuo Ishiguro. Full Text Available Questa riflessione affronta un tema assai rilevante per le professioni di cura, con uno sguardo particolare alla psicoterapia. The Azospirillum brasilense Che 1 chemotaxis pathway controls swimming velocity, which affects transient cell-to-cell clumping. The Che 1 chemotaxis-like pathway of Azospirillum brasilense contributes to chemotaxis and aerotaxis, and it has also been found to contribute to regulating changes in cell surface adhesive properties that affect the propensity of cells to clump and to flocculate.
The exact contribution of Che 1 to the control of chemotaxis and flocculation in A. Here, we show that Che 1 affects reversible cell-to-cell clumping, a cellular behavior in which motile cells transiently interact by adhering to one another at their nonflagellated poles before swimming apart. Clumping precedes and is required for flocculation, and both processes appear to be independently regulated. Our results also suggest that an additional receptor s and signaling pathway s are implicated in mediating other Che 1-independent changes in clumping identified in the present study.
Transient clumping precedes the transition to stable clump formation, which involves the production of specific extracellular polysaccharides EPS ; however, production of these clumping-specific EPS is not directly controlled by Che 1 activity. Che 1-dependent clumping may antagonize motility and prevent chemotaxis, thereby maintaining cells in a metabolically favorable niche. Atomi, molecole e solidi esercizi risolti.

The objectives of this research were to develop and evaluate a self-report questionnaire the Emotional Communication in Hearing Questionnaire or EMO- CHe Q designed to assess experiences of hearing and handicap when listening to signals that contain vocal emotion information. Study 1 involved internet-based administration of a item version of the EMO- CHe Q to adult participants with self-reported normal hearing [NH], with self-reported hearing impairment but no reported use of hearing aids [HI], and with self-reported hearing impairment and use of hearing aids [HA].
To better understand the factor structure of the EMO- CHe Q and eliminate redundant items, an exploratory factor analysis was conducted. In addition, participants completed an emotion-identification task under audio and audiovisual conditions. In study 1, the exploratory factor analysis yielded an interpretable solution with four factors emerging that explained a total of In study 2, the same pattern of reported handicap was observed in individuals with audiometrically verified hearing as was found in study 1. On the emotion-identification task, no group differences in performance were observed in the audiovisual condition, but group differences were observed in the audio alone condition.
Chemotaxis can provide bacteria with competitive advantages for survival in complex environments. A che Z gene has been found in Azorhizobium caulinodans ORS, in contrast to other rhizobial species studied so far. The Che Z protein in strain ORS has a conserved motif similar to that corresponding to the phosphatase active site in E. In addition, the properties of the che Z deletion mutant revealed that ORS Che Z is involved in other physiological processes, since it displayed increased flocculation, biofilm formation, exopolysaccharide EPS production, and host root colonization.
In particular, it was observed that the expression of several exp genes, involved in EPS synthesis, was upregulated in the che Z mutant compared to that in the wild type, suggesting that Che Z negatively controls exp gene expression through an unknown mechanism. It is proposed that Che Z influences the Azorhizobium -plant association by negatively regulating early colonization via the regulation of EPS production.
This report established that Che Z in A.

Site-specific and synergistic stimulation of methylation on the bacterial chemotaxis receptor Tsr by serine and Che W. Full Text Available Abstract Background Specific glutamates in the methyl-accepting chemotaxis proteins MCPs of Escherichia coli are modified during sensory adaptation. Attractants that bind to MCPs are known to increase the rate of receptor modification, as with serine and the serine receptor Tsr, which contributes to an increase in the steady-state adapted methylation level.
However, MCPs form ternary complexes with two cytoplasmic signaling proteins, the kinase Che A and an adaptor protein Che W, but their influences on receptor methylation are unknown. Here, the influence of Che W on the rate of Tsr methylation has been studied to identify contributions to the process of adaptation.
Results Methyl group incorporation was measured in a series of membrane samples in which the Tsr molecules were engineered to have one available methyl-accepting glutamate residue , , or The relative rates at these sites 0. The addition of Che W generated unexpectedly large and site-specific rate increases, equal to or larger than the increases produced by serine.
The rate increases were even larger when serine and Che W were added together, larger than the sums of the increases produced by serine and Che W added separately except site four. This resulted in substantially larger serine-stimulated increases when Che W was present. Also, Che W enhanced methylation rates when either two or all four sites were available. Conclusion The increase in the rate of receptor methylation upon Che W binding contributes significantly to the ligand specificity and kinetics of sensory adaptation. The synergistic effect of. Che Shift-2 resolves a local inconsistency between two X-ray crystal structures.
The availability of NMR resonance assignments that included the region of the inconsistency provided an opportunity for independent validation of the Che Shift-2 server. Previous NOE measurements had demonstrated that the position of a tryptophan ring in the region immediately N-terminal in this region was not consistent with either structure. The consensus between all of these measures suggests that the Che Shift-2 server operates well under circumstances in which backbone chemical shifts are available but where local plasticity may render X-ray structural data ambiguous.

Collaboration with other organisations that promote practices and procedures of quality assurance is essential, and appointed liaison persons The Pseudomonas aeruginosa chemotaxis methyltransferase Che R1 impacts on bacterial surface sampling. Full Text Available The characterization of factors contributing to the formation and development of surface-associated bacterial communities known as biofilms has become an area of intense interest since biofilms have a major impact on human health, the environment and industry.
Various studies have demonstrated that motility, including swimming, swarming and twitching, seems to play an important role in the surface colonization and establishment of structured biofilms. Thereby, the impact of chemotaxis on biofilm formation has been less intensively studied. Pseudomonas aeruginosa has a very complex chemosensory system with two Che systems implicated in flagella-mediated motility. In this study, we demonstrate that the chemotaxis protein Che R1 is a methyltransferase that binds S-adenosylmethionine and transfers a methyl group from this methyl donor to the chemoreceptor PctA, an activity which can be stimulated by the attractant serine but not by glutamine.
We furthermore demonstrate that Che R1 does not only play a role in flagella-mediated chemotaxis but that its activity is essential for the formation and maintenance of bacterial biofilm structures. We propose a model in which motility and chemotaxis impact on initial attachment processes, dispersion and reattachment and increase the efficiency and frequency of surface sampling in P. The Mars Science Laboratory Curiosity landed in Gale crater in August with the goal to identify and characterize habitable environments on Mars.
Curiosity has been studying a series of sedimentary rocks primarily deposited in fluviolacustrine environments approximately 3. Minerals in the rocks and soils on Mars can help place further constraints on these ancient aqueous environments, including pH, salinity, and relative duration of liquid water. The Chemistry and Mineralogy Che Min X-ray diffraction and X-ray fluorescence instrument on Curiosity uses a Co X-ray source and charge-coupled device detector in transmission geometry to collect 2D Debye-Scherrer ring patterns of the less than micron size fraction of drilled rock powders or scooped sediments.
With an angular range of approximately 2. Che Min has returned quantitative mineral abundances from 16 mudstone, sandstone, and aeolian sand samples so far. The mineralogy of these samples is incredibly diverse, suggesting a variety of depositional and diagenetic environments and different source regions for the sediments. Results from Che Min have been essential for reconstructing the geologic history of Gale crater and addressing the question of habitability on ancient Mars.

Chemotaxis is the movement of cells in response to gradients of diverse chemical cues.
Motile bacteria utilize a conserved chemotaxis signal transduction system to bias their motility and navigate through a gradient. A central regulator of chemotaxis is the histidine kinase Che A. This cytoplasmic protein interacts with membrane-bound receptors, which assemble into large polar arrays, to propagate the signal.
In the alphaproteobacterium Azospirillum brasilense , Che 1 controls transient increases in swimming speed during chemotaxis, but it also biases the cell length at division. However, the exact underlying molecular mechanisms for Che 1-dependent control of multiple cellular behaviors are not known. Here, we identify specific domains of the Che A1 histidine kinase implicated in modulating each of these functions. We show that Che A1 is produced in two isoforms: a membrane-anchored isoform produced as a fusion with a conserved seven-transmembrane domain of unknown function TMX at the N terminus and a soluble isoform similar to prototypical Che A.
Site-directed and deletion mutagenesis combined with behavioral assays confirm the role of Che A1 in chemotaxis and implicate the TMX domain in mediating changes in cell length. Fluorescence microscopy further reveals that the membrane-anchored isoform is distributed around the cell surface while the soluble isoform localizes at the cell poles. Together, the data provide a mechanism for the role of Che 1 in controlling multiple unrelated cellular behaviors via acquisition of a new domain in Che A1 and production of distinct functional isoforms.
The molecular principles that underlie functional diversification of chemotaxis in various genomic contexts are unknown. Here, we provide a molecular. Che cosa e come conosciamo dal romanzo. This internship provided opportunity to gain knowledge, experience, and skills in CHe CS engineering and operations tasks.

Senza farmi soverchie illusioni di essere riuscito nell'intento, mi dichiarerei tuttavia soddisfatto se questo lavoro destasse sull'argomento l'interesse di qualche giovane ricercatore, incoraggiandolo ad un approfondimento. We present Che SS, the "Chebyshev Sparse Solvers" library, which has been designed to solve typical problems arising in large-scale electronic structure calculations using localized basis sets.
The library is based on a flexible and efficient expansion in terms of Chebyshev polynomials and presently features the calculation of the density matrix, the calculation of matrix powers for arbitrary powers, and the extraction of eigenvalues in a selected interval. Che SS is able to exploit the sparsity of the matrices and scales linearly with respect to the number of nonzero entries, making it well-suited for large-scale calculations.
The approach is particularly adapted for setups leading to small spectral widths of the involved matrices and outperforms alternative methods in this regime. In addition, the approach based on Chebyshev polynomials can be massively parallelized, and Che SS exhibits excellent scaling up to thousands of cores even for relatively small matrix sizes. In addition to its role in DNA damage repair and recombination, the RecA protein, through its interaction with Che W, is involved in swarming motility, a form of flagella-dependent movement across surfaces.
In order to better understand how SOS response modulates swarming, in this work the location of RecA and Che W proteins within the swarming cells has been studied by using super-resolution microscopy. Further, and after in silico docking studies, the specific RecA and Che W regions associated with the RecA- Che W interaction have also been confirmed by site-directed mutagenesis and immunoprecipitation techniques. Our results point out that the Che W distribution changes, from the cell poles to foci distributed in a helical pattern along the cell axis when SOS response is activated or RecA protein is overexpressed.
In this situation, the Che W presents the same subcellular location as that of RecA, pointing out that the previously described RecA storage structures may be modulators of swarming motility. Data reported herein not only confirmed that the RecA- Che W pair is essential for swarming motility but it is directly involved in the Che W distribution change associated to SOS response activation. A model explaining not only the mechanism by which DNA damage modulates swarming but also how both the lack and the excess of RecA protein impair this motility is proposed.

Separation of the scintillation and Cherenkov light produced in liquid scintillators enables outstanding capabilities for future particle detectors, the most relevant being: particle directionality information in a low energy threshold detector and improved particle identification.
The Che SS experiment uses an array of small, fast photomultipliers PMTs and state-of-the-art electronics to demonstrate the reconstruction of a Cherenkov ring in liquid scintillator using two techniques: based on the photon density and using the photon hit time information. A charged particle ionizing a scintillation medium produces a prompt Cherenkov cone and late isotropic scintillation light, typically delayed by several ns. The fast response of our PMTs and DAQ provides a precision well below the ns level, making possible the time separation.

The structure and dynamic properties of the complete histidine phosphotransfer domain of the chemotaxis specific histidine autokinase Che A from Thermotoga maritima. The bacterial histidine autokinase Che A contains a histidine phosphotransfer Hpt domain that accepts a phosphate from the catalytic domain and donates the phosphate to either target response regulator protein, Che Y or Che B.
The Hpt domain forms a helix-bundle structure with a conserved four-helix bundle motif and a variable fifth helix. Observation of two nearly equally populated conformations in the crystal structure of a Hpt domain fragment of Che A from Thermotoga maritima containing only the first four helices suggests more mobility in a tightly packed helix bundle structure than previously thought.
In order to examine how the structures of Hpt domain homologs may differ from each other particularly in the conformation of the last helix, and whether an alternative conformation exists in the intact Hpt domain in solution, we have solved a high-resolution, solution structure of the Che A Hpt from T.
The structure contains a four-helix bundle characteristic of histidine phosphotransfer domains. The position and orientation of the fifth helix resembles those in known Hpt domain crystal and solution structures in other histidine kinases.

Novel activation domain derived from Che -1 cofactor coupled with the artificial protein Jazz drives utrophin upregulation. Our aim is to upregulate the expression level of the dystrophin related gene utrophin in Duchenne muscular dystrophy, thus complementing the lack of dystrophin functions.
To this end, we have engineered synthetic zinc finger based transcription factors. We have previously shown that the artificial three-zinc finger protein named Jazz fused with the Vp16 activation domain, is able to bind utrophin promoter A and to increase the endogenous level of utrophin in transgenic mice. This transcriptional activation domain is amino acids in size and it is very powerful as compared to the Vp16 activation domain. We show that CJ7 protein efficiently promotes transcription and accumulation of the acetylated form of histone H3 on the genomic utrophin promoter locus.

A new LIFE: oltre la didattica d'aula. A five year study. Full Text Available Introduction and Objectives: The appearance of nosocomial bacterial resistance represents a problem of growing concern because it largely affects the evolution of patients and the health resources devoted to it. The objective of this work was to determine the most common germs and their microbial resistance.
Methods: A descriptive retrospective study was carried out analyzing the result of the isolation of germs from all type of secretions and from the blood cultures of a group ofpatients hospitalized at the Ernesto Che Guevara Cardiology Hospital in a five year period. Results: A total of strains were isolated, 77 Staphylococcus aureus and Enterobacteriaceae. The Staphylococcus sensitive to methicillin presented 4. The strains resistant to methicillin or oxacillin had a high resistance to gentamicin Conclusions: the Staphylococcus aureus and the Enterobacteriaceae were the most common germs.
The preoperative prophylaxis in these patients must not be done with cefazolin as a routine because the staphylococci resistant to methicillin or oxacillin have influence on other antimicrobials. Il desiderio Kitsch: i troppi paradisi di Walter Siti. Atomistic structural ensemble refinement reveals non-native structure stabilizes a sub-millisecond folding intermediate of Che Y. The dynamics of globular proteins can be described in terms of transitions between a folded native state and less-populated intermediates, or excited states, which can play critical roles in both protein folding and function.
Excited states are by definition transient species, and therefore are difficult to characterize using current experimental techniques. We report an atomistic model of the excited state ensemble of a stabilized mutant of an extensively studied flavodoxin fold protein Che Y. We employed a hybrid simulation and experimental approach in which an aggregate 42 milliseconds of all-atom molecular dynamics were used as an informative prior for the structure of the excited state ensemble.
The most striking feature of the resulting excited state ensemble was an unstructured N-terminus stabilized by non-native contacts in a conformation that is topologically simpler than the native state. We then predict incisive single molecule FRET experiments, using these results, as a means of model validation. Our study demonstrates the paradigm of uniting simulation and experiment in a statistical model to study the structure of protein excited states and rationally design validating experiments.
