Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the etiological agent of coronavirus disease-2019 (COVID-19), is a highly contagious pathogenic coronavirus to emerge and spread in human populations. Although substantial exertions have been laid to avert spread of COVID-19 by therapeutic and preventive countermeasures, but emergence of SARS-CoV-2 variants as a result of mutations make the infection more ominous. New viral confers a higher nasopharyngeal viral load, increased viral transmissibility, higher infectiousness, immune escape, increased resistance to monoclonal/polyclonal antibodies from convalescence sera/vaccine, and an enhanced virulence. Thus, it is pertinent to monitor evolving mutations and genetic diversity of SARS-CoV-2 as it is decisive for understanding the viral variants. In this review we provide an overview of colloquial nomenclature and the genetic characteristics of different SARS-CoV-2 variants in the context of mutational changes of the circulating strains, transmissibility potential, virulence and infectivity. 相似文献

The Medical Library Association Cunningham Fellowship Program provides funds for one medical librarian per year from outside the United States or Canada to work and learn in United States or Canadian medical libraries for a period of 4 months. An overview of the Cunningham Fellowship is presented from three different points of view—that of a Medical Library Association member who has worked closely with the Cunningham Fellowship programme, and two former Cunningham Fellows. Anita Verhoeven, who relates her impressions of American culture, architecture and art, was the 1998 MLA Cuningham Fellow and visited 33 libraries, met 171 librarians, visited prestigious universities and attended a Medical Library Association meeting. Ioana Robu, the 1997 Cunningham Fellow, visited 15 libraries in 13 cities during her experience. She describes the process of applying for the fellowship and assesses the impact that the 1997 Cunningham Fellowship has made on her life, her library and medical librarianship in Romania. An overview of the Cunningham Fellowship is also given, which includes the history, the application process, the requirements of the fellowship and the time table of the fellowship. 相似文献

HIV/AIDS prevalence in South Africa is one of the highest in the world with heterosexual, transmission predominantly promoting the epidemic. The goal of this study is to examine whether, marijuana use and problem drinking mediate the relationship between histories of childhood sexual, abuse (CSA) and HIV risk behaviors among heterosexual men. Participants were 1181 Black men aged, 18–45 from randomly selected neighborhoods in Eastern Cape Province, South Africa. Audio computer assisted, self-interviewing was used to assess self-reported childhood sexual abuse, problem drinking, and marijuana (dagga) use, and HIV sexual transmission behavior with steady and casual partners. Data were analyzed using multiple meditational modeling. There was more support for problem, drinking than marijuana use as a mediator. Findings suggest that problem drinking and marijuana use, mediate HIV sexual risk behaviors in men with histories of CSA. Focusing on men with histories of CSA, and their use of marijuana and alcohol may be particularly useful for designing strategies to reduce, HIV sexual transmission in South Africa. 相似文献

Subject specialist college librarians can become producers and disseminators of knowledge by pursuing an active research agenda in their nonlibrary field. Research in an academic discipline can inform and enhance the college librarian's teaching, research, and collection development practices. Through such research, college librarians can elevate their personal status among their nonlibrary colleagues and students, as well as the prestige of their library and the library profession. Suggestions for managing traditional librarian duties and pursuing a nonlibrary research agenda are included. 相似文献

Procalcitonin (PCT) is an innovative and highly specific marker for diagnosis of clinically relevant bacterial infection and sepsis. PCT supports early diagnosis and Clinical decision making. A retrospective study of two classical cases of neutropenic sepsis with elevated PCT levels in cardiac ICU was done. PCT was analyzed using Elecsys Brahms PCT kit. Serum PCT levels <0.5 ng/ml and ANC <1,000/mm3 was taken as cutoff. The first patient had initial high levels of PCT 100 ng/ml, TLC 13,600/mm3 and ANC 12,250/mm3. It was followed by drop with subsequent rise in PCT levels and drop in TLC 1,000/mm3 and ANC 70/mm3. The second patient had normal PCT 0.116 ng/ml, TLC 5,600/mm3 and ANC 4,420/mm3 levels followed with sharp increase in all the values with subsequent drop in TLC 2,000/mm3 and ANC 880 cells/mm3. Both the patients died of neutropenic sepsis with multiorgan failure. The case reports showed the correlation of PCT with TLC and ANC levels in predicting the mortality of patients with neutropenic sepsis in cardiac ICU. 相似文献

In a case study of an undergraduate course in art education, modes of mastery learning and propositions of intellectual emancipation were explored as interventions in curriculum design. By adopting Rancière’s framework of a ‘will to will’ relationship between instructor and students, the core assignment—a visual journal—became a site of student positionality through mastery methods, rather than information gathering. The visual journal provided a record of the event of knowledge and served as a forum to verify that acts of student thinking were done with attention, congruent with Rancière’s perspective that learning generates greater consciousness, feeling and action. Requiring both qualitative and quantitative criteria within the parameters of the visual journal functioned as a means to experiment with the potential convergences of mastery and emancipatory approaches. The visual journal then operated as a third space where ongoing, consistent engagement demonstrated the capacity of students to encounter more equitable relations with the instructor and with the content in ways that have implications for knowledge creation in teaching and learning. 相似文献
