sophisticated equipment and skilled personnel, the RT-LAMP assay reported here is a valuable tool as a point-of-care diagnosis for the rapid and real-time detection of Ebola virus in resource-limited healthcare settings of developing countries.

Varicella zoster virus (VZV) strains are classified into six different clades based on the sequencing of its genome. Clades 4 and 5 are reported from India based on the single-nucleotide polymorphism (SNP). Till now, multiple clade circulations using partial sequences have been reported from India due to the lack of availability of the full VZV genome sequence. This study conducted a genome sequencing of VZV in India to identify circulating clade.

Four clinical samples obtained from symptomatic patients tested positive for VZV by real-time PCR were used. These four samples were preferred to retrieve the genomic VZV sequence using the next-generation sequencing method. A reference-based assembly method was used to retrieve the genome of VZV, which was further analyzed.

At the least, 98 per cent of the whole-genome sequences were recovered from the four samples. The VZV sequences obtained in this study formed a separate monophyletic branch with clade 5, indicating it to be evolved from a distinct ancestorngs to clade 5 and propose further experiments to confirm these results.

Working memory impairments in the subjects of opioid addiction may stem from an aberrant cortical activity in the executive areas, and may help in early identification of individuals with addictive tendencies and may also be used as a neurofeedback mechanism in adjunct to the existing therapeutics.

Electrical neuroimaging via 128-channel electroencephalography (EEG) recording was done in 15 male subjects with opioid addiction (29.45±5.6 yr) during the performance of Sternberg Working Memory Task. EEG data were acquired and analyzed for cortical sources during task as compared to resting (baseline) condition.

Working memory deficits were manifested as decrease in accuracy percentage in the subjects with opioid addiction, while no significant difference was seen in reaction time, on comparison with laboratory-acquired matched controls. Standardized low-resolution brain electromagnetic tomography (sLORETA)-based EEG source analysis revealed higher cortical activity in the anterior cingulate cortex, inferiore of deactivation of default-mode network (DMN) during the task amongst the subjects with opioid addiction. In addition, there was a decrease in the executive function areas in the subjects with opioid addiction. This lack of sufficiently active executive network and persistence of DMN during the task (as compared to baseline) may potentially form the basis of functional impairments in the subjects with opioid addiction.

Maternal morbidity is an indicator of the quality of a country's maternal health services. Maternal near miss (MNM) can provide valuable information in this context and hence these cases need to be reviewed which can indirectly play a major role in reducing maternal mortality ratio in India. D609 The objectives of the present review were to find the prevalence/incidence, criteria used for identification, review the causes of MNM cases and identify the contributory factors responsible for the occurrence of these cases based on three-delay model.

Articles were identified from the PubMed, Google Scholar, Scopus and Cochrane Library using search terms such as 'Maternal Near Miss','maternal morbidity', 'India' among others. All health facility-based observational studies conducted in India published between 2010 to 2019 irrespective of data collection period, and criteria used for identification of MNM cases were included for review. Data were extracted from included studies and summarized in terms of prevalence/inld follow the uniform criteria mentioned in the MNM-Review guidelines released by the Government of India in 2014 for obtaining systematic data and proper summary estimates.Immune checkpoint inhibitors (ICIs) are a relatively newer class of drugs approved for the treatment of malignancies such as melanoma, renal, bladder and lung cancer. Immune-related adverse events (IrAEs) involving the endocrine system are a common side effect of these drugs. The spectrum of endocrine adverse events varies by the drug class. Cytotoxic T-lymphocyte-associated antigen-4 inhibitors commonly cause hypophysitis/hypopituitarism, whereas the incidence of thyroid disease is higher with programmed cell death (PD)-1/ ligand (PD-L) protein 1 inhibitors. The focus of this review is to describe the individual endocrinopathies with their possible mechanisms, signs and symptoms, clinical assessment and disease management. Multiple mechanisms of IrAEs have been described in literature including type II/IV hypersensitivity reactions and development of autoantibodies. Patients with pre-existing autoimmune endocrine diseases can have disease exacerbation following ICI therapy rather than de novo IrAEs. Most of the endocrinopathies are relatively mild, and timely hormone replacement therapy allows continuation of ICIs. However, involvement of the pituitary-adrenal axis could be life-threatening if not recognized. Corticosteroids are helpful when the pituitary-adrenal axis is involved. In cases of severe endocrine toxicity (grade 3/4), ICIs should be temporarily discontinued and can be restarted after adequate hormonal therapy. Endocrinologists and general internists need to be vigilant and maintain a high degree of awareness for these adverse events.This study aimed to investigate the curative effect of spiral embedded flap urethroplasty for the treatment of meatal stenosis after penile carcinoma surgery. From January 2015 to January 2021, we used our technique to treat strictures of the external urethral orifice in seven patients, including four cases of meatal stenosis after partial penile resection and three cases of meatal stenosis after perineal stoma. All patients had previously undergone repeat urethral dilatation. The patients underwent spiral embedded flap urethroplasty to enlarge the outer urethral opening. The patients' mean age at the time of surgery was 60 (range 42-71) years, the mean operative time was 43 min, and the median follow-up period was 18 months. The patients voided well post-operatively, and urinary peak flow rates ranged from 18.3 ml s. All patients were successful with absence of urethral meatus stricture. The present study showed that using spiral embedded flap urethroplasty to treat meatal stenosis after penile carcinoma surgery is an effective surgical technique with good long-term outcomes.Infertility has become a serious disease since it affects 10%-15% of couples worldwide, and male infertility contributes to about 50% of the cases. Notably, a significant decrease occurs in the newborn population by 7.82 million in 2020 compared to 2016 in China. As such, it is essential to explore the effective methods of obtaining functional male gametes for restoring male fertility. Stem cells, including embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), spermatogonial stem cells (SSCs), and mesenchymal stem cells (MSCs), possess the abilities of both self-renewal and differentiation into germ cells. Significantly, much progress has recently been achieved in the generation of male germ cells in vitro from various kinds of stem cells under the specified conditions, e.g., the coculturing with Sertoli cells, three-dimensional culture system, the addition of growth factors and cytokines, and/or the overexpression of germ cell-related genes. In this review, we address the current advance in the derivation of male germ cells in vitro from stem cells based on the studies of the peers and us, and we highlight the perspectives and potential application of stem cell-derived male gametes in reproductive medicine.As shown in various preclinical studies, conventional type-1 dendritic cells, or cDC1s, play a critical role in the immunological rejection of tumors and in the defense against pathogens. This indispensability stems from their potent capacity to activate cytotoxic T cells, especially via the cross-presentation of exogenous antigens. For this reason, cDC1s have become an attractive target for immunotherapy. Here we report a simplified method for generating large numbers of cDC1-like cells in vitro from mobilized human peripheral blood CD34+ hematopoietic stem cells using FMS-like tyrosine kinase 3 ligand (FLT3L) and granulocyte-macrophage colony-stimulating factor (GM-CSF). An important aspect of this Protocol is the growth of cells on a non-tissue culture-treated surface rather than on a tissue culture-treated surface since the latter suppresses cDC1-marker expression. The resulting CD11c+ DCs express high levels of cDC1-specific markers such as CD141, CLEC9A, TLR3, and several DC maturation markers. Compared to alternative differentiation methods, this method generates large numbers of cDC1-like cells without the need for immortalized feeder cells and should prove useful for studying cDC1 immunobiology and clinical applications of this DC subset. © 2022 Wiley Periodicals LLC.

This reaction is facilitated by the consecutive action of three central enzymes, i.e., E1 activating enzyme, E2 conjugating enzyme, and the E3 ligase. More than 600 E3 enzymes guarantee the specificity and selectivity of these reactions and thus represent an exciting, while highly underrepresented, class of drug targets. Specific methods can be employed to monitor their activity and thus query compound libraries for inhibitory small molecules. Here, we describe two protocols-one high-throughput and one low-throughput method-to detect E3 ligase activity and test small molecule modulation. © 2022 The Authors.

Herein, a proton-driven transformable 1 O2 -nanotrap (ANBDP NPs) with endosomal escape capability is presented to improve hypoxic tumor PDT. In the acidic endosomal environment, the protonated 1 O2 -nanotrap ruptures endosomal membranes via a "proton-sponge" like effect and undergoes a drastic morphology-and-size change from nanocubes (≈94.1 nm in length) to nanospheres (≈12.3 nm in diameter). Simultaneously, anthracenyl boron dipyrromethene-derived photosensitizer (ANBDP) in nanospheres transforms to its protonated form (ANBDPH) and switches off its charge-transfer state to achieve amplified 1 O2 photogeneration capability. Upon 730 nm photoirradiation, ANBDPH prominently produces 1 O2 and traps generated-1 O2 in the anthracene group to form endoperoxide (ANOBDPH). Benefitting from the hypoxia-tolerant 1 O2 -release property of ANOBDPH in the dark, the 1 O2 -nanotrap brings about sustained therapeutic effect without further continuous irradiation, thereby achieving remarkable antitumor performance.
