Aspergillus fumigatus (Afu) causes allergic and invasive forms of diseases in humans. In order to identify genes relevant
for pathogenesis, a total of 235 cDNA clones were randomly selected and sequenced from cDNA library of Afu. One of the partially
sequenced cDNA clones was homologous to polyubiquitin. Sequencing of the complete cDNA clone showed an open reading frame
of 912 bases. Comparison with genomic sequence of Afu using BlastN program, revealed that polyubiquitin gene comprises of
992 bases and contains one intron of 80 bases. The recombinant expression of fusion protein showed an approximately molecular
weight of 43-kDa on SDS-PAGE. The translation product of the cDNA sequence showed four tandem repeats of 76 amino acid residues
in a single polyubiquitin protein and showed 100% identity with polyubiquitin protein sequences of S. cerevisiae, N. crassa,
C. albicans, S. pombe, and M. grisae. Polyubiquitin gene is known to play important role in a variety of cellular processes
and recently have been implicated in fungal pathogenesis. Identification of polyubiquitin gene of Afu has opened up scope
to study its role in understanding Aspergillus biology and pathogenesis. 相似文献

Students' perceptions of the education environment influence their learning. Ever since the major medical curriculum reform, anatomy education has undergone several changes in terms of its curriculum, teaching modalities, learning resources, and assessment methods. By measuring students' perceptions concerning anatomy education environment, valuable information can be obtained to facilitate improvements in teaching and learning. Hence, it is important to use a valid inventory that specifically measures attributes of the anatomy education environment. In this study, a new 11‐factor, 132‐items Anatomy Education Environment Measurement Inventory (AEEMI) was developed using Delphi technique and was validated in a Malaysian public medical school. The inventory was found to have satisfactory content evidence (scale‐level content validity index [total] = 0.646); good response process evidence (scale‐level face validity index [total] = 0.867); and acceptable to high internal consistency, with the Raykov composite reliability estimates of the six factors are in the range of 0.604–0.876. The best fit model of the AEEMI is achieved with six domains and 25 items (X2 = 415.67, P < 0.001, ChiSq/df = 1.63, RMSEA = 0.045, GFI = 0.905, CFI = 0.937, NFI = 0.854, TLI = 0.926). Hence, AEEMI was proven to have good psychometric properties, and thus could be used to measure the anatomy education environment in Malaysia. A concerted collaboration should be initiated toward developing a valid universal tool that, using the methods outlined in this study, measures the anatomy education environment across different institutions and countries.

Career indecision particularly among college and undergraduate students is a concern of counselors and psychologists. This concern has led to numerous research studies related to career indecision and factors that influence it, such as family relationships. In this regard, several studies have reported a significant relationship between career indecision and parental attachment. However, little research has been undertaken on the influence of this factor in regard to career indecision for Iranian students. For this purpose, 158 Iranian freshmen and sophomores who had completed the ‘Career Decision Scale’ (Osipow et al., Journal of Vocational Behavior 9:233–243, 1976) and had been identified as career-undecided, completed the ‘Inventory of Parents and Peer Attachment-Revised’ (Armsden & Greenberg, Journal of Youth and Adolescence 16:427–453, 1987). The results revealed that a significant negative relationship was found between career indecision and attachment to mother, whilst the relationship between career indecision and attachment to father was not significant. However, regression analysis showed parental attachment did not significantly predict career indecision of students. Implications and recommendations for further research are discussed. 相似文献

Karl Mahlburg brilliantly showed the importance of crank functions in partition congruences that were originally guessed by
Freeman Dyson. Ramanujan’s partition functions are the centre of these works. Not only for the theory on cranks, but for many
other researchers in India Ramanujan’s work inspired their career in mathematics. 相似文献

The coronavirus disease 2019 (Covid-19) pandemic caused an abrupt transition from face-to-face to online anatomy teaching, learning, and assessment. Although online education has ensured the continuity of anatomy education during the pandemic, its implementation has been challenging, and its effectiveness has been questioned. Therefore, literature pertinent to online anatomy education during the pandemic is crucial to explain Covid-19's disruptions to this field. Accordingly, this scoping review explored changes, disruptions, and gaps in anatomy teaching and assessment during Covid-19 using an enhanced version of Arksey and O′Malley's six-stage protocol. Five online databases were searched for articles that described changes and disruptions in anatomy education. Three independent researchers were involved in titles, abstracts, and full texts screening, while another four researchers were independently involved in data extraction, charting, and synthesis. This review revealed six themes: immediate strategic plans and actions, teaching and learning changes, online assessment practice, students' and educators' receptivity and adaptability, online learning and assessment effects, and future directions. It also revealed four gaps: non-future-ready curricula, learning obstacles, administrative and teaching challenges, and online education ethical issues. The results were reported in tabular and narrative forms, following the PRISMA Extension for Scoping Reviews (PRISMA-ScR guidelines). Understanding the evolution and gaps in anatomy education during the Covid-19 pandemic will help anatomists design future-ready, adaptable curricula. 相似文献
