An unusual clinical presentation of labial fusion in post pubertal period

Labial fusion is sealing of labia minora in midline, also known as labial adhesion or labial agglutination or synechia vulvae. This condition is common in pre-pubertal females usually asymptomatic when oestrogen levels are low and commonly resolves spontaneously post-puberty if unresolved medical treatment includes use of estrogen cream or betamethasone cream application, very rarely surgical treatment required, if not responding to medical treatment due to dense adhesions. This case report is unusual as it has presented in a post-pubertal female requiring surgical management

RECURRENT PREGNANCY LOSS AND ASSOCIATION OF MTHFR, PAI-1 AND ACE GENE POLYMORPHISMS IN WOMEN

Recurrent pregnancy loss (RPL) is a significant clinical problem that may occur before the 20th week of gestation. There is no general consensus on how many consecutive abortions are considered as RPL. The goal of this study is to investigate the correlation between recurrent miscarriage (RM) and common polymorphisms in angiotensin-converting enzyme (ACE), plasminogen activator inhibitor 1 (PAI-1) and Methylenetetrahydrofolate Reductase (MTHFR) genes among women experiencing RM. The literature existing in different population was searched and based on these finding we conclude that polymorphism in either one of these genes may increase chances of miscarriage.

CURATION AND MANAGEMENT OF CULTURAL HERITAGE THROUGH LIBRARIES

Libraries, museums and archives hold valuable collections in a variety of media, presenting a vast body of knowledge rooted in the history of human civilisation. These form the repository of the wisdom of great works by thinkers of past and the present. The holdings of these institutions are priceless heritage of the mankind as they preserve documents, ideas, and the oral and written records. To value the cultural heritage and to care for it as a treasure bequeathed to us by our ancestors is the major responsibility of libraries. The past records constitute a natural resource and are indispensable to the present generation as well as to the generations to come. Libraries preserve the documentary heritage resources for which they are primarily responsible. Any loss of such materials is simply irreplaceable. Therefore, preserving this intellectual, cultural heritage becomes not only the academic commitment but also the moral responsibility of the librarians/information scientists, who are in charge of these repositories. The high quality of the papers and the discussion represent the thinking and experience of experts in their particular fields. The contributed papers also relate to the methodology used in libraries in Asia to provide access to manuscripts and cultural heritage. The volume discusses best practices in Knowledge preservation and how to collaborate and preserve the culture. The book also deals with manuscript and archives issues in the digital era. The approach of this book is concise, comprehensively, covering all major aspects of preservation and conservation through libraries. The readership of the book is not just limited to library and information science professionals, but also for those involved in conservation, preservation, restoration or other related disciplines. The book will be useful for librarians, archivists and conservators. We thank the Sunan Kalijaga University, Special Libraries Association- Asian Chapter for their trust and their constant support, all the contributors for their submissions, the members of the Local and International Committee for their reviewing effort for making this publication possible

Knowledge Priorities on Climate Change and Water in the Upper Indus Basin: A Horizon Scanning Exercise to Identify the Top 100 Research Questions in Social and Natural Sciences

River systems originating from the Upper Indus Basin (UIB) are dominated by runoff from snow and glacier melt and summer monsoonal rainfall. These water resources are highly stressed as huge populations of people living in this region depend on them, including for agriculture, domestic use, and energy production. Projections suggest that the UIB region will be affected by considerable (yet poorly quantified) changes to the seasonality and composition of runoff in the future, which are likely to have considerable impacts on these supplies. Given how directly and indirectly communities and ecosystems are dependent on these resources and the growing pressure on them due to ever-increasing demands, the impacts of climate change pose considerable adaptation challenges. The strong linkages between hydroclimate, cryosphere, water resources, and human activities within the UIB suggest that a multi- and inter-disciplinary research approach integrating the social and natural/environmental sciences is critical for successful adaptation to ongoing and future hydrological and climate change. Here we use a horizon scanning technique to identify the Top 100 questions related to the most pressing knowledge gaps and research priorities in social and natural sciences on climate change and water in the UIB. These questions are on the margins of current thinking and investigation and are clustered into 14 themes, covering three overarching topics of ‘governance, policy, and sustainable solutions’, ‘socioeconomic processes and livelihoods’, and ‘integrated Earth System processes’. Raising awareness of these cutting-edge knowledge gaps and opportunities will hopefully encourage researchers, funding bodies, practitioners, and policy makers to address them

A positively charged side chain at position 154 on the β8–αE loop of HIV-1 RT is required for stable ternary complex formation

Lys154 is the only positively charged residue located in the VLPQGWK motif on the β8–αE loop at the junction of the fingers and palm subdomains of human immunodeficiency virus type 1 reverse transcriptase (HIV-1 RT). Some of the conserved residues in this motif are critical for RT function, while others have been shown to confer nucleoside drug resistance and fidelity to the enzyme. In order to understand the functional implication of this positively charged residue, we carried out site-directed mutagenesis at position 154 and biochemically characterized the mutant enzymes. Mutants carrying negatively charged side chains (K154D and K154E) were severely impaired in their polymerase function, while those with hydrophobic side chains (K154A and K154I) were moderately affected. Analysis of the binary complexes formed by these mutants revealed that all the mutant derivatives retained their ability to form an enzyme template primer (E–TP) binary complex similar to the wild-type enzyme. In contrast, their ability to form stable E–TP–dNTP ternary complexes varied greatly and was dependent on the nature of the side chain at position 154. The conservative Lys→Arg mutant was not affected in its ability to form a stable ternary complex, while those carrying non-polar or negatively charged side chains were significantly impaired. The apparent K(d [dNTP]) values for these non-conservative mutants were ∼16- to 400-fold higher than the wild-type enzyme, indicating that a positively charged side chain at position 154 may be required for efficient formation of a stable ternary complex. Interestingly, all the mutant derivatives of Lys154 were completely resistant to a nucleoside analog inhibitor, 3′-dideoxy 3′-thiacytidine (3TC), implying that Lys154 may play a role in conferring 3TC sensitivity to HIV-1 RT. These findings are discussed in the context of the binary and ternary complex crystal structures of HIV-1 RT

A PNA-transportan conjugate targeted to the TAR region of the HIV-1 genome exhibits both antiviral and virucidal properties

AbstractWe have earlier reported that anti-TAR PNA conjugated with the membrane-transducing peptide transportan inhibits transactivation of the HIV-1 LTR resulting in decreased production of HIV-1 virions by chronically infected H9 cells (N., Kaushik, A., Basu, P., Palumbo, R.L., Myers, V.N., Pandey, 2002. Anti-TAR polyamide nucleotide analog conjugated with a membrane permeating peptide inhibits HIV-1 production. J. Virol. 76, 3881–3891). In this study, we have found that the PNATAR-transportan conjugate is efficiently internalized by cells and kinetics analysis reveals a sigmoidal curve with a cooperativity index of 6, indicating very rapid cellular uptake. Additionally, analysis of uptake at varying temperatures or in the presence of phenylarsine oxide revealed that the mechanism of uptake is neither receptor-dependent nor occurs via endocytosis. We also found that the PNATAR-transportan conjugate exhibits potent virucidal activity as HIV-1 virions pretreated with the conjugate were rendered noninfectious, suggesting that the conjugate may also permeate the virus envelope. The anti-HIV-1 virucidal activity of the conjugate may be useful either in topical formulations designed to block HIV-1 infection or as a prophylactic agent for inactivation of HIV-1 in the circulating plasma prior to attachment and entry
