An Updated Phylogeny of mtDNA Haplogroup R8 Based on Complete Mitogenomes
In: The journal of the Anthropological Survey of India, Band 68, Heft 1, S. 114-122
ISSN: 2632-4369
Mitochondrial DNA (mtDNA) sequences reveal maternal phylogeny to trace back the demographic histories to construct phylogeny of a population. In this study, we update the phylogeny of the autochthonous Indian-specific mtDNA haplogroup R8 to give regional relationships between the members of haplogroup R8 in India and neighbouring areas. A set of 31 complete mitogenomes sequences from a Melakudiya tribal population of Southern India revealed two subclades of R8-R8a and R8b clustered with other tribal and caste populations of India. The updated coalescence age of haplogroup R8 in South Asia is dated ~43.3 ± 8.1 Kya, subclades R8a and R8b are dated ~40.6 ± 8.8 Kya and 15.4 ± 4.3 Kya, respectively. This study updated the deep in situ distribution of Indian-specific R8 lineages and added new daughter branches to the previously described branches of the haplogroup R8 in India.
COVID-19 testing in India in comparison to the rest of the world. If Indian testing strategy was replicated in the other top 15 COVID-19 affected countries in the world, the status would be startlingly different
In terms of the absolute number of COVID-19 positive cases, India is among the top four countries in the world. There is a lot of unwarranted criticism about the alleged inadequacy of COVID-19 testing in India. The facts available from international and publicly available online non-government source covering the entire world show otherwise. While India is fourth in terms of an absolute number of cases, its rank is 132(nd) in terms of cases per million population and 107(th) for deaths per million population. These are indications that India is doing much better in the battle against COVID-19 than it is getting credit for. The correct benchmark for the adequacy of testing is the percentage of COVID-19 positive results as compared to the total number of tests performed. India ranks 5(th) (out of 215) in this respect – being better than some western countries such as the USA, Spain, and France. Thus, the Indian strategy for COVID-19 testing is better and more appropriate than the majority of other countries with the large absolute number of positive cases.

Modulation of the mesenchymal stem cell secretome using computer-controlled bioreactors: impact on neuronal cell proliferation, survival and differentiation ; 2016 Jun 15
In recent years it has been shown that the therapeutic benefits of human mesenchymal stem/ stromal cells (hMSCs) in the Central Nervous System (CNS) are mainly attributed to their secretome. The implementation of computer-controlled suspension bioreactors has shown to be a viable route for the expansion of these cells to large numbers. As hMSCs actively respond to their culture environment, there is the hypothesis that one can modulate its secretome through their use. Herein, we present data indicating that the use of computer-controlled suspension bioreactors enhanced the neuroregulatory profile of hMSCs secretome. Indeed, higher levels of in vitro neuronal differentiation and NOTCH1 expression in human neural progenitor cells (hNPCs) were observed when these cells were incubated with the secretome of dynamically cultured hMSCs. A similar trend was also observed in the hippocampal dentate gyrus (DG) of rat brains where, upon injection, an enhanced neuronal and astrocytic survival and differentiation, was observed. Proteomic analysis also revealed that the dynamic culturing of hMSCs increased the secretion of several neuroregulatory molecules and miRNAs present in hMSCs secretome. In summary, the appropriate use of dynamic culture conditions can represent an important asset for the development of future neuro-regenerative strategies involving the use of hMSCs secretome. ; We acknowledge the financial support of the Portuguese Foundation for Science and Technology (FCT) for a Ciencia 2007 program and IF Development Grant (AJS), a pre-doctoral fellowship to FGT (SFRH/69637/2010) and a PhD fellowship to SA (SFRH/BD/81495/2011), a Canada Research Chair in Biomedical Engineering (LAB) and a SSE Postdoctoral Fellowship (KMP).

The effectiveness of a low-intensity problem-solving intervention for common adolescent mental health problems in New Delhi, India: protocol for a school-based, individually randomized controlled trial with an embedded stepped-wedge, cluster randomized controlled recruitment trial
Background Conduct, anxiety, and depressive disorders account for over 75% of the adolescent mental health burden globally. The current protocol will test a low-intensity problem-solving intervention for school-going adolescents with common mental health problems in India. The protocol also tests the effects of a classroom-based sensitization intervention on the demand for counselling services in an embedded recruitment trial. Methods/design We will conduct a two-arm, individually randomized controlled trial in six Government-run secondary schools in New Delhi. The targeted sample is 240 adolescents in grades 9–12 with persistent, elevated mental health symptoms and associated distress/impairment. Participants will receive either a brief problem-solving intervention delivered over 3 weeks by lay counsellors (intervention) or enhanced usual care comprised of problem-solving booklets (control). Self-reported adolescent mental health symptoms and idiographic problems will be assessed at 6 weeks (co-primary outcomes) and again at 12 weeks post-randomization. In addition, adolescent-reported distress/impairment, perceived stress, mental wellbeing, and clinical remission, as well as parent-reported adolescent mental health symptoms and impact scores, will be assessed at 6 and 12 weeks post-randomization. We will also complete a parallel process evaluation, including estimations of the costs of delivering the interventions. An embedded recruitment trial will apply a stepped-wedge, cluster (class)-randomized controlled design in 70 classes across the six schools. This will evaluate the added effect of a classroom-based sensitization intervention over and above school-level sensitization activities on the primary outcome of referral rate into the host trial. Other outcomes will be the proportion of referrals eligible to participate in the host trial, proportion of self-generated referrals, and severity and pattern of symptoms among referred adolescents in each condition. Power calculations were undertaken separately for ...

Integrating transcriptomic and proteomic data for accurate assembly and annotation of genomes ; Genome Research
Complementing genome sequence with deep transcriptome and proteome data could enable more accurate assembly and annotation of newly sequenced genomes. Here, we provide a proof-of-concept of an integrated approach for analysis of the genome and proteome of Anopheles stephensi, which is one of the most important vectors of the malaria parasite. To achieve broad coverage of genes, we carried out transcriptome sequencing and deep proteome profiling of multiple anatomically distinct sites. Based on transcriptomic data alone, we identified and corrected 535 events of incomplete genome assembly involving 1196 scaffolds and 868 protein-coding gene models. This proteogenomic approach enabled us to add 365 genes that were missed during genome annotation and identify 917 gene correction events through discovery of 151 novel exons, 297 protein extensions, 231 exon extensions,192 novel protein start sites,19 novel translational frames, 28 events of joining of exons, and 76 events of joining of adjacent genes as a single gene. Incorporation of proteomic evidence allowed us to change the designation of more than 87 predicted "noncoding RNAs" to conventional mRNAs coded by protein-coding genes. Importantly, extension of the newly corrected genome assemblies and gene models to 15 other newly assembled Anopheline genomes led to the discovery of a large number of apparent discrepancies in assembly and annotation of these genomes. Our data provide a framework for how future genome sequencing efforts should incorporate transcriptomic and proteomic analysis in combination with simultaneous manual curation to achieve near complete assembly and accurate annotation of genomes. ; Science and Engineering Research Board (SERB), Department of Science and Technology, Government of India [EMR/2014/000444]; DBT Program Support grant on "Development of infrastructure and a computational framework for analysis of proteomic data" [BT/01/COE/08/05]; Infosys Foundation; pilot grant from the Johns Hopkins Malaria Research Institute; Council of Scientific and Industrial Research, Department of Biotechnology, University Grants Commission; Department of Science and Technology, Government of India; Indian Council of Medical Research ; This paper is funded by the joint research project to NIMR and IOB entitled "Characterization of Malaria vector Anopheles stephensi Proteome and Transcriptome" (EMR/2014/000444) from the Science and Engineering Research Board (SERB), Department of Science and Technology, Government of India.
