This review article is dedicated to a relatively young, actively developing approach to biodiversity assessment analysis of environmental DNA (or eDNA). Current views on the nature of eDNA, a brief overview of the history of this approach and methods of eDNA analysis are presented. Major research directions, utilizing eDNA techniques, and perspectives of their application to the study of biodiversity are described. Key issues in development of eDNA approach, its advantages and drawbacks are outlined.

Deadly Disease

Nipah viral encephalitis is one of the fatal re-emerging infections especially in southeast Asia. After its outbreak in Malaysia and Singapore; repeated outbreaks occurred at western part of Bangladesh especially in Faridpur region. Besides, sporadic attacks appear to occur in the country throughout the year. Here two Nipah outbreaks in greater Faridpur district in 2003 and 2004 are described along with brief review on transmission of the virus. Where the history of illness among patients are very much in favour of man to man transmission. Moreover the death of an intern doctor from Nipah encephalitis who was involved in managing such patients in Faridpur Medical College Hospital strongly suggests man to man transmission of this virus. So, aim of this review article to make the health personnel and general people be aware about man to man transmission of virus, so that they can adapt personal protection equipment (PPE) for their protection against this deadly disease.

Interest in psychiatric neurosurgery has waxed and waned since the 1930s. This chapter reviews the history of these methods, with a focus on OCD. This review of lesion procedures and deep brain stimulation includes neuropsychological and neuroimaging research in the context of putative neurocircuitry underlying symptoms and response to treatment. The chapter highlights how an abundance of caution is needed, as well as key issues in long-term management of patients so treated.

In the publication, O.V. Konovalova, V.I. Fedorova, A.P. Dvoretskaya presented letters 1931-1932 of the leader and theoretician of the party of socialists-revolutionaries V.M. Chernov to a prominent figure of the party O.S. Minor and a representative of Harbin socialists-revolutionaries organization M. I. Klyaver regarding the split of the Foreign delegation of the socialists-revolutionaries. They are preserved in the collection of VM. Chernov of the International Archives and Collections at the International Institute of Social History in Amsterdam. The presented letters help to clarify VM. Chernov’s position on the key issues of the history of the SR party during the Russian revolution, Civil War, and emigration of the 1920s, and also shed light on the deep reasons for the split of the ZD AKP.

The Relationship

<p>For decades, paleoecological studies in lake sediments have focused on reconstructing the environments of the past and explaining phenomena linked to climatic variations. Recent advances in high-throughput DNA sequencing have allowed access to environmental DNA (eDNA) and ancient sedimentary DNA (sedaDNA) as a new and efficient proxy for past and present biodiversity. The basin of Mexico (BM) is located in the central part of the Trans-Mexican Volcanic Belt at 2,200 m a.s.l.; with the southern portion harboring the Chalco sub-basin. Lake Chalco is one of the last remaining natural aquatic ecosystems within the ever-expanding urban area surrounding Mexico City. The paleoenvironmental history of this lake has been previously characterized using sedimentological and geochemical proxies, as well as preserved microfossils (diatoms, pollen) with a temporal framework based on multiple radiocarbon dates. However, information for the remaining taxonomic groups and metabolic pathways remained unexplored. Here, we present the first metagenomics-based study for the Holocene in a high-altitude lake in Central Mexico –Lake Chalco. We explored the relationship between the lake’s paleoenvironmental condition and estimations of taxonomic and metabolic profiles across the sedimentary sequence (2.5 meters long). Multiple biological and abiotic variables revealed three main environmental phases: 1) a cool freshwater lake (FW1: 11,500-11,000 cal years BP), 2) a warm hyposaline lake (HS2: 11,000-6,000 cal years BP), and 3) a temperate, subsaline lake (SS3, <6,000 cal years BP). We describe the structure of the microbiota community and taxonomy richness turnover in the three Holocene paleoenvironmental phases. During the past 12 000 years BP the most abundant domains in Lake Chalco sediments were Bacteria, followed by Archaea, and Eukarya (36,722 genera). The analysis of functional proteins showed high biodiversity with a total of 27,636,243 proteins identified, but it was only possible to annotate 3,227,398 of them. Also, we identified several genes associated with some relevant pathways, such as methanogenesis. Altogether, this study allowed us to reconstruct the natural history of lake Chalco and its surroundings.</p>

Purpose The purpose of this review article is to examine the well-being of faculty in higher education. Success in academia depends on productivity in research, teaching, and service to the university, and the workload model that excludes attention to the welfare of faculty members themselves contributes to stress and burnout. Importantly, student success and well-being is influenced largely by their faculty members, whose ability to inspire and lead depends on their own well-being. This review article underscores the importance of attending to the well-being of the people behind the productivity in higher education. Method This study is a narrative review of the literature about faculty well-being in higher education. The history of well-being in the workplace and academia, concepts of stress and well-being in higher education faculty, and evidence-based strategies to promote and cultivate faculty well-being were explored in the literature using electronic sources. Conclusions Faculty feel overburdened and pressured to work constantly to meet the demands of academia, and they strive for work–life balance. Faculty report stress and burnout related to excessively high expectations, financial pressures to obtain research funding, limited time to manage their workload, and a belief that individual progress is never sufficient. Faculty well-being is important for the individual and in support of scholarship and student outcomes. This article concludes with strategies to improve faculty well-being that incorporate an intentional focus on faculty members themselves, prioritize a community of well-being, and implement continuous high-quality professional learning.
