However, the knowledge about the microbial community and property of the marine sediments is still limited. In the present study, the salt tolerance of the microorganisms in the marine sediment that was collected from a marine fish farm was investigated by being used as inoculum for anaerobic digestion. The microbial communities were analyzed by high-throughput sequencing. The inoculum from the wastewater plant (IWTP) was taken as a control. The inoculum from the marine sediment (IMS) showed excellent capacity for anaerobic digestion at salinities of 0.3%-6%. Even at a salinity of 9%, the methane yield remained 60% of the highest yield. IMS provides promising microbial resources for the treatment of both fresh-water and saliferous organic wastes. While the IWTP was sensitive to salt, the methane yield decreased to 56% of the highest yield at the salinity of 3%. The bacterial taxonomic richness of IMS was about half of that in IWTP. Eighty-one genera were identified only in IWTP but not in IMS. The IMS possessed fewer bacterial members related to the nitrogen cycle than IWTP, but more members related to the sulfur cycle. The members of animal parasites or symbionts in IMS were significantly fewer than those in IWTP. read more The archaeal compositions of IMS and IWTP were different. The relative abundance of the unidentified archaea in IMS was much higher than that in IWTP with 12.52% vs 0.06% at phylum level. The findings of this work expand our understanding of the microorganisms in marine sediments and will promote the application of them in waste treatment.
. Extreme ambient temperature has an adverse effect on pregnancy outcomes, but the conclusions have been inconsistent. The influence of ambient temperature and diurnal temperature variation on the premature rupture of membranes (PROM) needs further study.

. The daily data of PROMs, daily meteorological and air pollutant were obtained. After controlling for potential confounding factors, the quasi-Poisson generalized additive model (GAM) combined with the distributed lag nonlinear model (DLNM) was used to analyze the association between temperature or diurnal temperature variation and PROM, including preterm premature rupture of membranes (PPROM) and term premature rupture of membranes (term PROM). Compared with the median temperature(18.7°C), the mean temperature of 5-7 days lagging beyond 31.5°C and below -1.5°C was positively correlated with PROM; the mean temperature had more sensitive effect on the term PROM. Exposure to extremely high temperatures (97.5
percentile, 32°C) had a 6-day lagging relativure changes.The disadvantages of limited working pH range and poor stability have hindered the practical application of traditional electro-Fenton process. In this research, a novel heterogeneous electro-Fenton (HEF) process with FeIIFeIII layered double hydroxide/carbon felt (FeIIFeIII LDH/CF) as cathode was developed for the rapid destruction of ciprofloxacin (CIP) in bulk solution. Effects of crucial influencing factors (initial pH, current intensity) on CIP degradation were investigated. Results indicated that FeIIFeIII LDH/CF cathode was efficient for CIP degradation (88.11%). Furthermore, CIP degradation performance in HEF could remain stable over wide range of pH (pH 3-9). The catalytic degradation of CIP in HEF process might be a combined effect of homogeneous EF reaction, anodic oxidation, and surface catalysis process via≡FeII/≡FeIII cycle. Possible degradation pathways were proposed. The results suggested that FeIIFeIII LDH/CF cathode showed great application potential for CIP degradation.The study aims at the Isolation, screening and antibacterial evaluation of Camptothecin (CPT) and its derivatives, an anticancer molecule from endophytic fungus Diaporthe caatingaensis MT192326 of the medicinal plant, Buchanania axillaris. Plant parts were collected from Sathyamangalam Tiger Reserve forest, Tamil Nadu. The fungus was isolated using DEKM07 medium was used as the screening medium for the presence of CPT. The strain with the highest yield of CPT was identified at the molecular level by 18S rDNA sequencing. CPT was isolated and analyzed by UV-Vis spectrophotometry, Thin layer chromatography, High-Performance Liquid Chromatography, Fourier Transform Infrared spectroscopy, and Electron spray ionization-mass spectrometry. The compounds identified by ESI-MS from the fungal extract were studied for their antibacterial assays against procured MTCC bacterial pathogens. The maximum yield of 0.681 mg/L of CPT was produced by the fungus D.caatingaensis. CPT derivatives were identified at m/z of 305, 348 and 389 through ESI-MS analysis. Antibacterial studies revealed that the endophytic fungal extract compounds were studied for antibacterial activities of disc diffusion assay, exhibiting a growth inhibition range of 15-22 mm in nutrient agar plate medium. The Minimum Inhibitory Concentration revealed the antibacterial potential at a lower concentration of 12.5-25 μg/ml with all bacteria studied. The relatively lower antimicrobial efficacy of partially purified bio-metabolites than the positive control streptomycin (3.125) concentration could be due to the presence of derivatives of the compounds that hinder the activity of the biometabolite. This is the first initiative to screen, isolate and analyze the antibacterial assays of CPT and derivatives from endophytic fungus D.caatingaensis of ethnopharmacologically important B.axillaris plant from STRF.
Increased understanding of whether individuals who have recovered from COVID-19 are protected from future SARS-CoV-2 infection is an urgent requirement. We aimed to investigate whether antibodies against SARS-CoV-2 were associated with a decreased risk of symptomatic and asymptomatic reinfection.

A large, multicentre, prospective cohort study was done, with participants recruited from publicly funded hospitals in all regions of England. All health-care workers, support staff, and administrative staff working at hospitals who could remain engaged in follow-up for 12 months were eligible to join The SARS-CoV-2 Immunity and Reinfection Evaluation study. Participants were excluded if they had no PCR tests after enrolment, enrolled after Dec 31, 2020, or had insufficient PCR and antibody data for cohort assignment. Participants attended regular SARS-CoV-2 PCR and antibody testing (every 2-4 weeks) and completed questionnaires every 2 weeks on symptoms and exposures. At enrolment, participants were assigned to infection. This time period is the minimum probable effect because seroconversions were not included. This study shows that previous infection with SARS-CoV-2 induces effective immunity to future infections in most individuals.

To identify the spectrum and frequency of mutations in congenital ectopia lentis (CEL) and to investigate the correlations between genotype and clinical phenotype in Chinese CEL patients.

Ninety-three participants with CEL were enrolled from March 2017 to April 2020. Ocular and systemic examinations were performed for each included patient. Genomic DNA from the included patients was analysed by whole-exome sequencing to detect mutations. Clinical manifestations were compared for different mutation subgroups.

Gene mutations were detected in 79 patients. Sixty-five were FBN1-associated, and most were related to Marfan syndrome (MFS). The FBN1 mutations mainly consisted of missense mutations (49/65) and were concentrated in the 5' region. Probands with missense mutations tend to show high corneal astigmatism (χ
=3.98, P=0.046) and severe lens dislocation (t=2.90, P=0.006) compared to premature termination codon (PTC) mutations.

Most Chinese CEL patients were identified as having FBN1 mutations. Those with missense mutations commonly showed severe ocular phenotypes; therefore, reinforced follow-up and long-term observation are required. These correlations implicated the crucial role of missense and cysteine-involving mutations in ocular phenotypes, which might be explained by dominant-negative and nonsense-mediated mRNA decay (NMD).

Although the underlying events leading to RGC death are not fully understood, recent research efforts are beginning to define the genetic changes that play a critical role in the initiation and progression of glaucomatous injury and RGC death. Several genetic and experimental animal models have been developed to mimic glaucomatous neurodegeneration. These models differ in many respects but all result in the loss of RGCs. Assessing transcriptional changes across different models could provide a more complete perspective on the molecular drivers of RGC degeneration. For the past several decades, changes in the retinal transcriptome during neurodegeneration process were defined using microarray methods, RNA sequencing and now single cell RNA sequencing. It is understood that these methods have strengths and weaknesses due to technical differences and variations in the analytical tools used. In this review, we focus on the use of transcriptome-wide expression profiling of the changes occurring as RGCs are lost across different glaucoma models. Commonalities of optic nerve crush and glaucoma-induced neurodegeneration are identified and discussed.
Posterior capsular opacification (PCO) is the major vision-disrupting complication arising after cataract surgery. Circular RNAs (circRNAs) are biological active RNAs which were involved in various physiological functions. So far, the role of circRNA caspase recruitment domain family member 6 (circ-CARD6) in PCO is still unclear.

Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to detect the expression of circ-CARD6, microRNA 31 (miR-31) and fibroblast growth factor 7 (FGF7) message RNA (mRNA). Western blot was used to analyze the protein expression. Transmission electron microscopy (TEM) was employed to capture the exosome image. The proliferation and metastasis were analyzed by cell counting kit-8 (CCK8), transwell and wound healing assays. The potential binding sequences between miR-31 and circ-CARD6 or FGF7 were respectively predicted by Circinteractome and Targetscan online tool, and verified by dual-luciferase reporter and RNA binding protein immunoprecipitation (RIP) assays.

Exosome-transmitted circ-CARD6 was highly expressed in PCO tissues and TGF-β2-treated SRA01/04cells.
