Tuberculosis (TB) is a disease of public health importance globally. The incidence of pulmonary TB is rising in sub-Saharan Africa. Bilateral adrenal destruction and the use of medications such as rifampicin are possible mechanisms by which TB cause adrenal insufficiency. Failure to promptly recognize adrenal insufficiency may lead to a medical crisis causing death. This systematic review aimed to identify the frequency of adrenal insufficiency, the clinical presentation and its predictors in patients with pulmonary TB in sub-Saharan Africa.<br /><br /> The study was a systematic review. Medical databases and the grey literature were searched. Literature search and studies selection were done following the PRISMA guidelines.<br /><br /> The total sample size was 809. The frequency of adrenal insufficiency among patients with pulmonary TB in sub-Saharan Africa was 0.9%-59.8%. Patients with adrenal insufficiency had symptoms such as nausea, vomiting, darkening of the skin, salt craving, and weight loss. Other symptoms were dry, itchy skin, abdominal pain, and muscle pain. The predictors of adrenal insufficiency among patients with pulmonary TB in sub-Saharan Africa were low blood pressure, low blood glucose, presence of multidrug-resistant TB, and low CD4 count. Other predictors were abdominal pain and generalized skin hyperpigmentation.<br /><br /> The frequency of adrenal insufficiency in patients with pulmonary TB can be as high as 50%. The presence of low blood pressure, low blood glucose, multidrug-resistant TB, and generalized skin hyperpigmentation is a pointer to the possibility of adrenal insufficiency in these patients.<br /><br />The frequency of adrenal insufficiency in patients with pulmonary TB can be as high as 50%.

Angiotensin converting enzyme 2 (ACE2) and trans-membrane protease serine 2 (TMPRSS2) are the two major host factors that contribute to the virulence of SARS-CoV-2 and pathogenesis of coronavirus disease-19 (COVID-19). Transmission of SARS-CoV-2 from animal to human is considered a rare event that necessarily requires strong evolutionary adaptations. Till date no other human cellular receptors are identified beside ACE2 for SARS-CoV-2 entry inside the human cell. Proteolytic cleavage of viral spike (S)-protein and ACE2 by TMPRSS2 began the entire host-pathogen interaction initiated with the physical binding of ACE2 to S-protein. SARS-CoV-2 S-protein binds to ACE2 with much higher affinity and stability than that of SARS-CoVs. Molecular interactions between ACE2-S and TMPRSS2-S are crucial and preciously mediated by specific residues. Structural stability, binding affinity and level of expression of these three interacting proteins are key susceptibility factors for COVID-19. Specific protein-protein interactions (PPI) are being identified that explains uniqueness of SARS-CoV-2 infection. Amino acid substitutions due to naturally occurring genetic polymorphisms potentially alter these PPIs and poses further clinical heterogeneity of COVID-19. Repurposing of several phytochemicals and approved drugs against ACE2, TMPRSS2 and S-protein have been proposed that could inhibit PPI between them. We have also identified some novel lead phytochemicals present in Azadirachta indica and Aloe barbadensis which could be utilized for further in vitro and in vivo anti-COVID-19 drug discovery. Uncovering details of ACE2-S and TMPRSS2-S interactions would further contribute to future research on COVID-19.Human clear cell renal cell carcinoma (ccRCC) is the most common and frequently occurring histological subtype of RCC. Unlike other carcinomas, candidate predictive biomarkers for this type are in need to explore the molecular mechanism of ccRCC and identify candidate target genes for improving disease management. For this, we chose case-control-based studies from the Gene Expression Omnibus and subjected the gene expression microarray data to combined effect size meta-analysis for identifying shared genes signature. Further, we constructed a subnetwork of these gene signatures and evaluated topological parameters during the gene deletion analysis to get to the central hub genes, as they form the backbone of the network and its integrity. Parallelly, we carried out functional enrichment analysis using gene ontology and Elsevier disease pathway collection. We also performed microRNAs target gene analysis and constructed a regulatory network. We identified a total of 577 differentially expressed genes (DEGs), where 146 overexpressed and 431 underexpressed with a significant threshold of adjusted P values less then 0.05. Enrichment analysis of these DEGs' functions showed a relation to metabolic and cellular pathways like metabolic reprogramming in cancer, proteins with altered expression in cancer metabolic reprogramming, and glycolysis activation in cancer (Warburg effect). Our analysis revealed the potential role of PDHB and ATP5C1 in ccRCC by altering metabolic pathways and amyloid beta precursor protein (APP) role in altering cell-cycle growth for the tumour progression in ccRCC conditions. Identification of these candidate predictive genes paves the way for the development of biomarker-based methods for this carcinoma.Amorphophallus, a perennial herb belongs to the family Araceae, and is widely distributed in Asia and Africa. As an agricultural crop, it has been cultivated and consumed for ~2000 years in China. Previous studies have found that there are chromosome number and ploidy changes in this genus, but there are a few reports on the evolution of different karyotypes. For this study, we collected 37 samples of a wild population of Amorphophallus muelleri from Myanmar and analysed their karyotypes. The karyotype analysis showed that it is a population with mixed chromosome numbers and ploidy, with four karyotypes of 2n = 24, 26, 28 and 39. Combining the results of this study with previous literature, we speculate that karyotypes with 2n = 26 may be the common ancestor, and further the other three karyotypes were evolved from this by various ways. As far as we know, this is the first attempt to put forward the hypothesis of the evolution of those four karyotypes together.
