Aim Genomic analysis of a methicillin-resistant Staphylococcus aureus (MRSA) strain cultured from a non-migratory seabird at Fernando de Noronha Archipelago (Brazilian oceanic islands) was carried out to investigate the potential origin of MRSA genetic determinants in an ecological setting with minimal or absent antimicrobial selective pressure, and minimal interaction with humans and domestic animals. Results The study determined mecA gene homology and the phylogenetic relatedness with mecA described in Staphylococcus sciuri, which was the major Staphylococcus spp. cultured from the birds. Our findings corroborate in silico assumptions that the mecA gene in MRSA strains clinically relevant for humans and animals originates from S. sciuri ancestors. Conclusion Coagulase-negative staphylococci seem to be natural reservoirs of methicillin-resistant genes to S. aureus, even in environments with very low antimicrobial selection pressure.Hydroxytyrosol (HT) from olives and polyphenols from almond skin (ASPs) possess cardioprotective properties. This pilot study evaluates the effect of supplementation with a combination of olive fruit and almond skin extracts on low-density lipoprotein (LDL) cholesterol oxidation, lipid homeostasis, and inflammatory parameters in adults with moderate hypercholesterolemia. A randomized, parallel, double-blind, placebo-controlled pilot study of 8 weeks was performed. The extract group (EG) received the supplement with 7.5 mg HT +210 mg ASPs, and the control group (CG) received a placebo composed of maltodextrin. Oxidized LDL (oxLDL) levels and the oxLDL/LDL ratio were lower in the EG than in the CG after 8 weeks of treatment (18.76 ± 3.91 vs. 10.34 ± 4.22, P  less then  .001 and 0.151 ± 0.025 vs. 0.08 ± 0.023, P  less then  .001, respectively). Interleukin-1β levels were significantly higher in the CG than in the EG at week 4 (P = .004), IL-6 was significantly higher in the CG than in the EG at week 4 (P = .049), and IL-10 was significantly increased at week 4 in both groups (P = .002 for CG and P = .001 for EG). In conclusion, daily consumption of a combination of an olive fruit extract and an almond skin extract for 8 weeks seems to protect LDL from oxidation and to prevent inflammatory status in moderately hypercholesterolemic subjects.In recent years in China, leaf spot caused by Colletotrichum species has been an emerging disease of Philodendron tatei cv. Abivertinib molecular weight Congo. From 2016 to 2019, typical symptoms, appearing as circular or ovoid, sunken, and brown lesions with a yellow halo, were commonly observed on P. tatei cv. Congo in and around Lanzhou, Gansu Province, China. Conidiomata were often visible on infected leaf surfaces. Leaf disease incidence was approximately 5 to 20%. A total of 126 single-spored Colletotrichum isolates were obtained from leaf lesions. Multilocus phylogenetic relationships were analyzed based on seven genomic loci (ITS, ACT, GAPDH, HIS3, CAL, CHS-1, and TUB2) and the morphological characters of the isolates determined. These isolates were identified as three Colletotrichum species in this study. A further 93 isolates, accounting for 74% of all Colletotrichum isolates, were described as new species and named as Colletotrichum philodendricola sp. nov. after the host plant genus name, Philodendron; another two isolates weis the first report of Colletotrichum species associated with anthracnose diseases on P. tatei cv. Congo. Results obtained in this study will assist the disease prevention and appropriate management strategies.To identify novel regulators of nonmuscle myosin II (NMII) we performed an image-based RNA interference screen using stable Drosophila melanogaster S2 cells expressing the enhanced green fluorescent protein (EGFP)-tagged regulatory light chain (RLC) of NMII and mCherry-Actin. We identified the Rab-specific GTPase-activating protein (GAP) RN-tre as necessary for the assembly of NMII RLC into contractile actin networks. Depletion of RN-tre led to a punctate NMII phenotype, similar to what is observed following depletion of proteins in the Rho1 pathway. Depletion of RN-tre also led to a decrease in active Rho1 and a decrease in phosphomyosin-positive cells by immunostaining, while expression of constitutively active Rho or Rho-kinase (Rok) rescues the punctate phenotype. Functionally, RN-tre depletion led to an increase in actin retrograde flow rate and cellular contractility in S2 and S2R+ cells, respectively. Regulation of NMII by RN-tre is only partially dependent on its GAP activity as overexpression of constitutively active Rabs inactivated by RN-tre failed to alter NMII RLC localization, while a GAP-dead version of RN-tre partially restored phosphomyosin staining. Collectively, our results suggest that RN-tre plays an important regulatory role in NMII RLC distribution, phosphorylation, and function, likely through Rho1 signaling and putatively serving as a link between the secretion machinery and actomyosin contractility.Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver injury and liver transplantation in Western countries. The pathogenesis of NAFLD includes overnutrition-associated metabolic syndrome or the improper consumption of dietary macro- and micro-nutrients that either support or prevent disease development. This altered nutrient landscape has been linked to shifts within the gut microbiota which can exacerbate liver pathology and the progression of NAFLD. Treatment goals for NAFLD target lifestyle and dietary modifications that restrict calories and adjust macronutrient content. It is not well understood how different macronutrients alter the microbiota and whether the diet-educated microbiota contribute to the resolution of disease. We fed mice a diet high in fat, cholesterol and fructose for 6 weeks and then in two different arms of the study, intervened with either a diet high in saturated and polyunsaturated fats and fiber or low in fats and fiber. In a second set of experiments, we performed microbiota transplants using cecal contents from mice fed one of the intervention diets to assess whether the diet-educated microbiota could impact clinical outcomes in mice fed a NAFLD-inducing diet. Pathology, steatosis, ALT/AST levels, and liver cytokine levels were measured as primary outcomes. We found that despite different microbiota compositions, both of the intervention diets reversed the progression of NAFLD and dampened inflammation. In contrast, transplantation of cecal contents from the intervention diet-fed mice to mice receiving a NAFLD-inducing diet was unable to prevent disease progression, and, in some cases, worsened disease. These data underscore the importance of dietary modifications to treat NAFLD and caution against the use of microbiota transplantation in the absence of dietary and lifestyle modifications.
