influenzae for matches in the genome. It was observed that all primers and probes for the E-gene of SARS-CoV-2 had over 13 bp long sequences matching 100% with multiple sites across the H. influenzae genome. This qRT-PCR primer & probes are being used extensively across India, and laboratories using them should be aware of the cross-reactivity of primers & probes with the H. influenzae genome. Further, the authors observed that 95.9% (5415/5642) of COVID-19 positive cases detected in their laboratory were asymptomatic at the time of collection of samples. This warrants further investigations.
  This study is aims at evaluating the efficacy and sensitivity of specimen pooling for testing of SARS-CoV-2 virus to determine the accuracy, resource savings, and identification of borderline positive cases without impacting the accuracy of the testing.
 
  This study was conducted between August and October 2020, we performed COVID-19 testing by RT-PCR on the samples from varying prevalence of rural population (non-hot spot) referred to COVID laboratory, in the first step, the samples were collated into pools of 5 or 10. These pools were tested by RT-PCR. Negative pools were reported as negative whereas positive pools of 5 and 10 were then de-convoluted and each sample was tested individually.
 
  In the present study, we tested 1580 samples in 158 pools of 10 and 17,515 samples in 3503 pools of 5. Among 10 samples pool, 11 (13%) pools flagged positive in the first step. In the second step, among 11 pools (110 samples) de-convoluted strategy was followed in which 10 individual samples came positive. Among 5 sast. In particular, the pooled sample approach can facilitate mass screening in the early asymptomatic stages of COVID-19 infections.As the world fights with the Coronavirus, most of the hospitals are gearing up for the care of these patients. As most of the attention these days is being given on Coronavirus, the patients suffering from other clinical infections are being neglected. SARS-CoV-2 is being kept as the top differential in patients presenting with fever and respiratory distress. We hereby present a case of patient returning from Indonesia during the pandemic presenting with a history of hepatic, renal dysfunction with fever and cough. Due to the pandemic, the patient's fever and cough outweighed the hepatic and renal dysfunction, and the patient had to undergo dialysis before the final diagnosis of leptospirosis could be made.
  The treatment of SARS CoV2 (Severe Acute Respiratory Syndrome corona virus 2) also known as COVID-19 (corona virus disease 2019) continues to remain an enigma even after six months of the pandemic.  https://www.selleckchem.com/products/l-arginine-l-glutamate.html  Hydroxychloroquine (HCQ) has been one of the most widely tested drugs for SARS CoV2 on account of its antiviral properties. However the results so far have been far from categorical. The meta-analyses conducted till date are also lacking in precision and appropriateness. This systematic review and meta-analysis addresses the efficacy and safety of HCQ in SARS CoV2 by overcoming the limitations of earlier meta-analysis.
 
  A total of 5 prominent medical databases were searched and fourteen studies (n = 12455) were included in the systematic review and meta-analyses. The data on survival, alleviation of symptoms, conversion of RT PCR positivity to negativity, use and efficacy in presence of co-morbidities (Hypertension, diabetes and heart disease) and cardiac and gastrointestinal side effects were extracted. Meta-andrugs in SARS CoV2 infection.
  The intracavernosal (IC) injection of chitosan activated platelet rich plasma (cPRP) has shown to improve the erectile dysfunction in cavernous nerve injury rat model. However, the action target of PRP in improving neurogenic erectile dysfunction remains unclear. We aimed to determine the effect of cPRP action at early stage that further mediates its effect on erectile function (EF) recovery in the bilateral cavernous nerve crushing (BCNC) injury rat model.
 
  Fifty-four rats were randomly divided into two equal groups intracavernosal ( IC) injection of saline after BCNC (group 1) and IC injection of cPRP after BCNC (group 2). Five animals in each group were euthanized at 3, 7 and 14 day (d) post-injection, and the tissues were harvested to conduct transmission electron microscopy and histological assays. Six animals in each group were used to determine the recovery of EF at 14 and 28d post-injury.
 
  IC injections of cPRP increased all EF parameters at 28d and 14d post-injury (p<0.05). cPRP injections simultaneously prevented the loss of neuronal nitric oxide synthase-positive neurons (p<0.05) and nerve fibers (p<0.05) in the major pelvic ganglion and cavernous nerve (CN), respectively, compared with saline injections. This simultaneous accelerated the regeneration of myelinated axons of the CN, reduced apoptosis, and enhanced the proliferation of the corporal smooth muscle cells at an earlier stage.
 
  These results suggest that the application of cPRP was beneficial to restore EF via neuroprotective and tissue-protective effects at early stage.

In this study we have therefore investigated if glycosaminoglycans on immune cells act in concert with GPC receptors (i.e. both being cis-located on leukocytes) in chemokine-induced leukocyte mobilisation. For this purpose, freshly-prepared human neutrophils and monocytes were treated with heparinase III or chondroitinase ABC to digest heparan sulfate -chains or chondroitin sulfate-chains, respectively, from the leukocyte surfaces. Subsequent analysis of CXCL8- and CCL2-induced chemotaxis revealed that leukocyte migration was strongly reduced after eliminating heparan sulfate from the surface of neutrophils and monocytes. In the case of monocytes, an additional dependence of CCL2-induced chemotaxis on chondroitin sulfate was observed. We compared these results with the effect on chemotaxis of a heparan sulfate masking antibody and obtained similarly reduced migration.
