Bacterial endophytes are found in the internal tissues of plants and have intimate associations with their host. However, little is known about the diversity of medicinal plant endophytes (ME) or their capability to produce specialised metabolites that may contribute to therapeutic properties. We isolated 75 bacterial ME from 24 plant species of the Western Ghats, India. Molecular identification by 16S rRNA gene sequencing grouped MEs into 13 bacterial genera, with members of Gammaproteobacteria and Firmicutes being the most abundant. To improve taxonomic identification, 26 selected MEs were genome sequenced and average nucleotide identity (ANI) used to identify them to the species-level. This identified multiple species in the most common genus as Bacillus. Similarly, identity of the Enterobacterales was also distinguished within Enterobacter and Serratia by ANI and core-gene analysis. AntiSMASH identified non-ribosomal peptide synthase, lantipeptide and bacteriocin biosynthetic gene clusters (BGC) as the most common BGCs found in the ME genomes. Teniposide cell line A total of five of the ME isolates belonging to Bacillus, Serratia and Enterobacter showed antimicrobial activity against the plant pathogen Pectobacterium carotovorum. Using molecular and genomic approaches we have characterised a unique collection of endophytic bacteria from medicinal plants. Their genomes encode multiple specialised metabolite gene clusters and the collection can now be screened for novel bioactive and medicinal metabolites.Solitary species often employ chemocommunication to facilitate mate localization. In the solitarily foraging, nocturnal mouse lemurs (Microcebus spp.), females advertise their short period of estrus acoustically and by increased scent marking, whereas males search widely for receptive females. Both sexes can be trained by operant conditioning to discriminate conspecific from heterospecific urine scent. However, it is not known, if males during and outside the reproductive season show different spontaneous interest in conspecific female urine, and if urine from estrous females elicits a higher investigation response than that from diestrous females. We established a spontaneous discrimination paradigm and quantified olfactory investigation responses of 21 captive male mouse lemurs of M. lehilahytsara and M. murinus when presenting 1 conspecific and 1 heterospecific female urine odor sample simultaneously. Overall, M. murinus investigated stimuli significantly longer than M. lehilahytsara. Moreover, males of M. murinus showed significantly longer olfactory investigation at conspecific urine samples during but not outside the reproductive season. This indicates that female urinary cues are spontaneously discriminated by male M. murinus and that this discrimination is more relevant during the reproductive season. However, males of both species did not show different responses toward urine samples from estrous versus diestrous females. Finally, male age did not correlate with the overall duration of olfactory investigation, and investigation levels were similar when testing with fresh or frozen urine samples. In conclusion, this new spontaneous discrimination paradigm provides a useful additional tool to study olfactory communication of nocturnal primates from the receiver's perspective.76 days after the COVID-19 epidemic was contained in Wuhan, the Chinese government carried out a citywide SARS-CoV-2 nucleic acid testing for all the residents from May 14th to June 1st, 2020. Our hospital tested 107,662 residents around Huanan Seafood Market, uncovering a positivity rate of 0.006%.

Although the FDA recently approved the HPV vaccine for individuals aged 27-45 years old, the CDC did not change their guidelines for routine HPV vaccination. Since recommendations for adult vaccination emphasize shared clinical decision-making based on risk of new infections, we examined the relationship between HPV prevalence and sexual behavior.

This study was conducted among 5,093 HPV-unvaccinated, sexually experienced adults aged 18-59 years in the National Health and Nutrition Examination Survey (2013-2016). For each sex and age group, adjusted prevalences of 9-valent vaccine-specific, high-risk, and any-HPV infection were estimated by number of lifetime sexual partners (LTSP) using logistic regression. An analysis restricted to persons who did not have a new sexual partner in the past year (i.e., removing those at highest risk of newly acquired HPV) was also conducted.

In each age group, genital HPV prevalence was higher among persons with >5 LTSP compared with 1-5 LTSP in both males and females. There were only slight reductions in HPV prevalence after removing participants who reported a new sexual partner in the past year. For example, among females aged 27-45 years with >5 LTSP, the adjusted prevalence of 9-valent vaccine-type HPV infection was 13.4% (95% CI 9.9-17.0) in the full group compared to 12.1% (95% CI 8.8-15.4) among those with no new sexual partners.

Prevalent HPV infection was primarily reflective of cumulative exposures over time (higher LTSP). New exposures had limited impact, emphasizing the need to consider sexual history in the decision-making process for adult HPV vaccination.

Ulcerative colitis [UC] patients are at an increased risk of developing colorectal cancer due to chronic inflammation. Endoscopic submucosal dissection [ESD] allows removal of non-invasive neoplastic lesions in the colon, but few data are available on its efficacy in UC patients.

Data from consecutive UC patients diagnosed with visible dysplastic lesions in the colon who underwent ESD were evaluated. The en bloc removal, R0 resection and complication rates were calculated. Local recurrence and metachronous lesions during follow-up were identified. A systematic review of the literature with pooled data analysis was performed.

A total of 53 UC patients [age 65 years; range 30-74; M/F 31/22] underwent ESD. The en bloc resection rate was 100%, and the R0 resection rate was 96.2%. Bleeding occurred in seven [13.2%] patients, and perforation in three [5.6%] cases, all treated at endoscopy. No recurrence was observed, but two metachronous lesions were detected. Data from six other studies [three Asian and three European] were available.
