Pathogenic oral microorganisms inside hospitalised people using dysphagia: The particular quiet outbreak.
2 gene, 98.61% homology to C.cassiicola (MH263735) with 287 bp for EF-1α gene. And all 9 sequences were submitted to GenBank (GenBank accession No. MT334575-77 for rDNA-ITS, MT886387-89 for TUB2, and MT886390-92 for EF-1α).The molecular identification and morphological characteristics showed that the isolated strains from Jasminum sambac were identified as C.cassiicola. C. cassiicola has an extensive host range, covering 397 host plants (Farr and Rossman 2020). Recently, C.cassiicola has been reported on Jasminum mesnyi of Oleaceaein China (Zhang et al. 2018). To our knowledge, this is the first report of leaf spot caused by C.cassiicola on Jasminum sambac in China and also worlwide.Tea (Camellia sinensis (L.) O. Kuntze) is a very popular beverage and cash crop that is widely cultivated in tropical and subtropical areas. In November 2017, diseased tea plants that exhibiting brown blight disease were observed in Guanxi Township of Hsinchu County in Taiwan. In the plantation,15% of tea trees (about 4000 plants) had an average of 20% of the leaves with at least one lesion. The symptoms began as small, water-soaked lesions on young leaves and twigs and later became larger, dark brown, necrotic lesions of 1 to 3 cm in diameter on leaves and 2 to 5 cm in length on twigs. Symptomatic leaf tissue (1 cm2) from five samples per sample) was surface sterilized with 1% NaClO (from commercial bleach, Clorox) for 1 min, washed with sterilized water 3 times, plated onto potato dextrose agar (PDA), and incubated under 12h/12h cycles of light and darkness at 25°C until sporulation to determine the causal agent. https://www.selleckchem.com/products/lazertinib-yh25448-gns-1480.html A fungus was consistently isolated from symptomatic leaf samples (80% isolation rate). The fungter (a water control). The tea plants were covered with plastic bags to maintain high relative humidity for two days. One week after inoculation, anthracnose was observed on 40% of inoculated leaves, whereas all the control leaves remained healthy. The fungus was re-isolated from the diseased plants, and identified as C. fructicola by resequencing of the four genes. To the best of our knowledge, this is the first report of anthracnose caused by C. fructicola on tea in Taiwan although the pathogen has been present in China and Indonesia (Wang et al. 2016; Shi et al. 2017; Farr and Rossman, 2020).We developed a loop-mediated isothermal amplification (LAMP) assay for detecting Fusarium oxysporum f. sp. fragariae, the causal agent of wilt in strawberry plants. This assay was based on genomic regions between the portions of transposable elements Han and Skippy of the fungus. The LAMP assay allowed the efficient detection of F. oxysporum f. link2 sp. fragariae DNA by visual inspection, without requiring gel electrophoresis. The detection limit was 100 pg of genomic DNA, which is comparable to that of PCR. The LAMP primers successfully discriminated F. oxysporum f. sp. fragariae strains from nonpathogenic F. oxysporum strains and other fungi. The LAMP assay at 63°C, which was found to be the optimal treatment temperature, for 1.5 h successfully detected F. link3 oxysporum f. sp. fragariae California strains GL1270 and GL1385. When the assay was performed using a Genelyzer FIII portable fluorometer, these California strains were successfully detected in 1 h. The assay facilitated the detection of conidia in soil samples after they were precultured on a selective medium for F. oxysporum (FoG2) as well as latent infection in strawberry plants after preculturing. The LAMP assay for visual inspection of DNA required only a heating block and an incubator, reducing the cost of this assay. Thus, it could be suitable for the detection of F. oxysporum f. sp. fragariae strains in centers that store prefoundation and foundation stocks of strawberry, including plant nurseries.Adiponectin regulates white adipose tissue (WAT) metabolism and promotes insulin-sensitizing and anti-atherosclerotic effects in vivo. In this context, small molecule adiponectin receptor agonists have become of great therapeutic value for the treatment of metabolic diseases. Here, we investigated the effects of the adiponectin mimetic compound ALY688 on WAT metabolism. To accomplish this, rat epididymal (Epid) and subcutaneous inguinal (Sc Ing) adipocytes were isolated and incubated with ALY688. Subsequently, several parameters of glucose and fat metabolism were assessed. ALY688 promoted AMP-activated protein kinase (AMPK) and acetyl-CoA carboxylase (ACC) phosphorylation, enhanced glucose oxidation, and suppressed fat oxidation in adipocytes from both fat depots. ALY688 did not affect basal and insulin-stimulated rates of glucose uptake, glucose incorporation into lipids, and AKTSer473 and p38 mitogen-activated protein kinase (MAPK) phosphorylations in either Epid or Sc Ing adipocytes. ALY688 did not alter basal lipolysis in Epid and Sc Ing adipocytes, but it enhanced isoproterenol-induced lipolysis in Epid adipocytes. Adiponectin receptor 2 (AdipoR2) mRNA was the prevalent isoform expressed in all adipocytes, and Epid adipocytes displayed significantly higher AdipoR2 mRNA expression than Sc Ing adipocytes. In conclusion, ALY688 can regulate adiposity and affect glycaemic control by altering substrate portioning in the WAT in a fat depot-specific manner.Chandipura virus (CHPV) is an emerging pathogen responsible for acute encephalitic syndrome (AES) in pediatric population in India. Several outbreaks of CHPV have been reported from different states of India since the year 2003. At present there is no vaccine or therapeutic measures available to curtail the disease. In this study, we have identified both T-cell and B-cell epitopes of different antigenic proteins of CHPV like Nucleoprotein (N), Phosphoprotein (P) and Matrix protein (M) along with the immuno-dominant glycoprotein (G) and conducted in silico characterization for the same. The idea is to design a multi-epitope peptide construct using the epitopes, which were found to be non-toxic, non-allergenic and possessing high immunogenicity. The final multi-epitope construct named as MEC-CHPV, comprised of β-defensin adjuvant at N-terminal for enhancement of immunogenicity followed by fourteen B-cell epitopes, four Helper T-cell epitopes and six Cytotoxic T-cell epitopes. The characterization of designed construct was carried out in terms of physicochemical parameters, antigenicity and allergenicity. The 3D structure prediction was performed. Molecular docking and molecular-dynamics simulation of MEC-CHPV with Toll like receptors (TLR-3 and TLR-8) showed stable interactions. In silico cloning of MEC-CHPV in pET30a(+) expression vector was also conducted using codon optimization. The in silico immune-simulation indicated a typical immune response against MEC-CHPV when used as a potential vaccine. This study provides a cost-effective and time-saving way to design a peptide vaccine candidate against CHPV using immuno-informatics approach. Development of the MEC-CHPV construct may pave the way for future laboratory experiments. Communicated by Ramaswamy H.

Currently, there is no approved vaccine or drug available to combat the pandemic. COVID-19 main protease (Mpro) is a key CoV enzyme, which plays an important role in triggering viral replication and transcription, turns it into an attractive target. Therefore, we aim to screen natural products library to find out potential COVID-19 Mpro inhibitors. Plant-based natural compounds from Sigma-Aldrich plant profiler chemical library have been screened through virtual molecular docking and molecular dynamics simulation to identify potential inhibitors of COVID Mpro. Our virtual molecular docking results have shown that there are twenty-eight natural compounds with a greater binding affinity toward the COVID-19 Mpro inhibition site as compared to the co-crystal native ligand Inhibitor N3 (-7.9 kcal/mol). Also, molecular dynamics simulation results have confirmed that Peonidin 3-O-glucoside, Kaempferol 3-O-β-rutinoside, 4-(3,4-Dihydroxyphenyl)-7-methoxy-5-[(6-O-β-D-xylopyranosyl-β-D-glucopyranosyl)oxy]-2H-1-benzopyran-2-one, Quercetin-3-D-xyloside, and Quercetin 3-O-α-L-arabinopyranoside (selected based on the docking score) possess a significant amount of dynamic properties such as stability, flexibility and binding energy. Our In silco results suggests that all the above mention natural compounds have the potential to be developed as a COVID-19 Mpro inhibitor. But before that, it must go through under the proper preclinical and clinical trials for further scientific validation. Communicated by Ramaswamy H. Sarma.Homeless youth experience increased risk of contracting HIV, making HIV testing imperative in this population. We analyzed factors associated with HIV testing among homeless youth in Atlanta, Georgia using data from the 2015 Atlanta Youth Count and Needs Assessment. The analysis included 693 homeless youth aged 14-25 years, of whom 88.4% reported ever being tested for HIV, and 74.6% reported being tested within the previous year. Prevalence of ever testing for HIV was significantly higher among youth who reported risk factors for HIV (sexually active, transactional sex, or ever having an STI). Higher prevalence of testing within the last year was significantly associated with experiencing physical abuse or transactional sex. However, reporting ≥ 4 sexual partners or not using condoms were not associated with higher testing. Although testing prevalence among homeless youth was high, homeless youth engaging in certain high risk behaviors could benefit from further promotion of HIV testing.Justice-involved youth are at high risk for HIV and STIs, and justice agencies are uniquely poised to offer HIV/STI testing. However, testing in these settings is not routine and represents a missed opportunity. This study describes a system-level implementation intervention designed to increase access to HIV/STI testing through juvenile justice (JJ) and public health agency collaboration across six counties in six states in the United States. Local change teams, active facilitation, and training were utilized to facilitate agency partnerships and development of HIV/STI practice change protocols. Five counties established health and JJ partnerships and four counties successfully implemented their protocols. Sites with HIV/STI education and testing protocols behaviorally screened 98.5% of youth and tested 41.2% of those youth; 0% were HIV+ and 43.2% had an STI. The intervention provides a feasible, scalable solution, through promoting partnerships between JJ and health agencies, to link youth to testing and treatment services.Understanding why clients stop taking pre-exposure prophylaxis (PrEP) is critical to improve PrEP delivery and ultimately reduce HIV incidence. We analyzed data from a programmatic evaluation conducted at the Los Angeles LGBT Center from February to May 2018. Of 180 respondents to the emailed survey, 91 had stopped taking PrEP and 11 never started. Among former PrEP users, most common reasons for stopping were entering a monogamous relationship (43%) and side effects (40%). Ten of 11 who never started PrEP reported access barriers (e.g., cost, insurance problems). A quarter of inactive clients re-engaged with PrEP services following the survey and 15% restarted PrEP by October 2018. Improving PrEP retention may require multifaceted interventions-e.g., tailored discussions about stopping and restarting PrEP safely as HIV risk changes, ensuring consistent access to affordable PrEP, and alternative dosing strategies. An emailed survey may be a simple, effective strategy to reengage some PrEP clients.
