PURPOSE Genetic studies have identified the association of some single-nucleotide polymorphisms (SNPs) with polypoidal choroidal vasculopathy (PCV), but little is known about whether these SNPs are related to PCV clinical features as well. We performed this study to examine the association of 12 SNPs with PCV clinical phenotypes. METHODS Sixty-nine PCV eyes of 69 patients were included. Genomic DNA was extracted from peripheral blood. Agilent SureSelect Human ALL Exon V6 was used to sequence the 12 SNPs previously reported to associate with PCV. Baseline best-corrected visual acuity (BCVA), sub-foveal choroidal thickness (SFCT), choroid maximum vascular diameter (MVD), choroidal vascular hyperpermeability (CVH), and greatest linear dimension (GLD) of entire lesion were measured and compared between patients of different genotypes. Fisher's exact test and Mann-Whitney U test were mainly used to compare categorical variables and continuous variables respectively. RESULTS HTRA1 rs2293870 was a protective factor of PCV or AMD in the fellow eye (P = 0.040) and was related with greater SFCT in PCV eye after multiple linear regression (P = 0.043). C3 rs17030 was associated with smaller GLD (P = 0.033). read more CFH rs2274700 was related to lower MVD (P = 0.043) and was a protective factor for CVH (P = 0.034). CONCLUSION Multiple PCV-associated SNPs are associated with PCV clinical phenotypes. The involvement of several synonymous SNPs calls for further research on the role of transcriptional alterations and trans-regulation of distant signaling pathways in PCV pathogenesis.We isolated two Candida pseudointermedia strains from the Atlantic rain forest in Brazil, and analyzed cellobiose metabolization in their cells. After growth in cellobiose medium, both strains had high intracellular β-glucosidase activity [~ 200 U (g cells)-1 for 200 mM cellobiose and ~ 100 U (g cells)-1 for 2 mM pNPβG] and negligible periplasmic cellobiase activity. During batch fermentation, the strain with the best performance consumed all the available cellobiose in the first 18 h of the assay, producing 2.7 g L-1 of ethanol. Kinetics of its cellobiase activity demonstrated a high-affinity hydrolytic system inside cells, with Km of 12.4 mM. Our data suggest that, unlike other fungal species that hydrolyze cellobiose extracellularly, both analyzed strains transport it to the cytoplasm, where it is then hydrolyzed by high-affinity intracellular β-glucosidases. We believe this study increases the fund of knowledge regarding yeasts from Brazilian microbiomes.A Gram-stain-negative, aerobic, and motile strain, TJ48T, was isolated from pakchoi-cultivated soil contaminated with Cd and Pb in Xinxiang (China). Cells of the strain were rod-shaped and colonies on LB agar were faint yellow. Strain TJ48T was positive for catalase and oxidase and the optimal condition for growth was 28 °C, with 1% (w/v) NaCl and at pH 7.0. Phylogenetic analysis based on the 16S rRNA gene sequences showed that strain TJ48T was closely related to the genus Rhodobacter and the closest relatives were Rhodobacter ovatus JA234T (97.4%, 16S rRNA gene sequence similarity) and Rhodobacter azotoformans KA25T (96.5%). The DNA G + C content of strain TJ48T was 64.7 mol%. Genome-to-genome distance calculations (GGDC) and ANIb values from genomic comparison between the genomes of strain TJ48T and the related reference species were less than 70% and 95%, respectively. The major cellular fatty acids were summed feature 8 (C181ω7c and/or C181ω6c) and C170. The only isoprenoid quinone detected was Ubiquinone-10 (Q-10). The polar lipid profile contains diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminophospholipid, one unidentified phospholipids, and three unidentified lipids. Strain TJ48T significantly increased the dry weight of roots (26.2-66.3%) and shoots (16.7-37.8%) of pakchoi and reduced the Cd (50.2-60.1%) and Pb (55.6-60.9%) contents in pakchoi shoots and roots. On the basis of the physiological, genotypic and genomic characteristics, the strain TJ48T represent a novel species of the genus Rhodobacter, and the name Rhodobacter xinxiangensis sp. nov. is proposed (type strain TJ48T = CCTCC AB2019120T = KCTC 72510T).Cultured microalgae are the primary food source for oyster larvae during hatchery culture and are a potential vector for Vibrio spp. infection of larval cultures. Bacteriophages have shown potential for controlling contamination of Vibrio spp. in aquaculture systems and their application could be an effective biological control method to eliminate such bacterial contamination of microalgae. This study investigated whether Vibrio-free microalgae sources could be ensured via the application of Vibrio specific phages. As a first step, four different Vibrio bacteriophages (belonging to the Myoviridae viral family) were isolated from marine waters in Queensland, Australia and used in challenge tests against a Vibrio host species, previously isolated from New South Wales oyster hatchery and found to be closely related to V. alginolyticus (ATCC 17749). The genome sequence of one of the four isolated bacteriophages, Vibrio Φ-2, that displayed strongest virulence against the host was determined. The 242446 bp genome of this bacteriophage was predicted to encode 217 proteins with an average GC content of 43.91%, containing putative thymidine kinases and a lysin enzyme. Application of these bacteriophages to pathogenic Vibrio spp. contaminating microalgae suspensions resulted in significant decreases in their numbers within 2 h. Findings indicated that direct application of bacteriophages to microalgae suspensions could be an effective method of reducing the occurrence of vibriosis in oyster hatcheries.The red pigment production by Talaromyces purpureogenus KKP, a soil isolate, was optimized by response surface methodology (RSM) in the present study. The cultural parameters, such as pH, temperature, dextrose, and peptone concentrations, were optimized for red pigment production using the central composite design (CCD) experimental design. A second-order quadratic model was used to calculate the relationships between the values at different levels of response. The optimum values of the selected variables under coded factors are 6.0, 27 °C, 2.25%, and 1.10% for pH, temperature, dextrose, and peptone, respectively. The selected variables were most effective in the enhancement of red pigment production at optimized culture conditions. In addition to optimization, the antioxidant activity of the pigment isolated in the present study was found to be promising with IC50 value (40 µg/ml). The HRMS data revealed the identification of delphinidin, limonene, 6-hydroxymethyl-7,8-dihydropterin, D-mannose 6-phosphate, and CDP-DG (180/180).
