xylanicola (0.487 U mg-1) and Saitozyma podzolica (0.384 U mg-1). The results showed that rotting wood collected from the Atlantic Rainforest is a valuable source of yeasts able to grow in sugarcane bagasse hydrolysate, including species with promising biotechnological properties.In nature, microorganisms often exhibit competitive behavior for nutrients and limited space, allowing them to alter the virulence determinants of pathogens. The human pathogenic yeast Cryptococcus neoformans can be found organized in biofilms, a complex community composed of an extracellular matrix which confers protection against predation. The aim of this study was to evaluate and characterize antagonistic interactions between two cohabiting microorganisms C. neoformans and the bacteria Serratia marcescens. The interaction of S. marcescens with C. neoformans expressed a negative effect on biofilm formation, polysaccharide capsule, production of urease, and melanization of the yeast. These findings evidence that competition in mixed communities can result in dominance by one species, with direct impact on the physiological modulation of virulence determinants. Such an approach is key for understating the response of communities to the presence of competitors and, ultimately, rationally designing communities to prevent and treat certain diseases.Mucor circinelloides is an opportunistic dimorphic pathogen, with the dimorphic process controlled in parts by fermentative and oxidative metabolisms, which lead to yeast or mycelial growth, respectively. Dimorphic transition is important for pathogenesis since the mycelium represents the virulent morphology. We previously reported that the deletion of arl1 or arl2 stimulate anaerobic germination in M. circinelloides, suggesting an augmented fermentative metabolism. In the present study, we demonstrate that the heterokaryon Δarl1(+)(-) and homokaryon Δarl2 strains contain low number of mitochondria, which possibly results in a dysfunctional oxidative metabolism, marked by a low oxygen consumption in glucose and poor growth in glycerol as the unique carbon source. This dysfunction is compensated for by an increase in the glycolysis and fermentation in aerobic conditions, demonstrating growth kinetics similar to that in the wild-type strain. Moreover, as a consequence a high fermentative activity, the Δarl1(+)(-) and Δarl2 strains possibly increased the yeast cell growth during low oxygen concentrations in presence of glucose. To the best of our knowledge, this is the first study to demonstrate the control of members of Arf family on the mitochondrial population in a Mucor species.Most fungi are multinucleated organisms. In some fungi, they have asynchronous nuclei in the same cytoplasm. We analyzed a cell-cycle regulation mechanism using a model fungus Neurospora crassa, which can make heterokaryon cells. Selleck 2-NBDG G1/S cyclin CLN-1 and cyclin-dependent kinase CDC-2 were tagged with different fluorescence in different strains and expressed. By forming a heterokaryon strain of these, two different fluorescence-tagged proteins were expressed in the same cytoplasm. CDC-2 was localized in all nuclei, whereas CLN-1 was not detected in most of the nuclei and was dispersed in the cytoplasm with small granular clusters. This indicates that in multinucleated fungi, cell-cycle regulators, similar to other proteins, are shared around the nuclei regardless of different cell-cycle stages. Moreover, each nucleus can select and use a special cell-cycle regulator only when it is necessary. Fungal nuclei may have a novel pickup mechanism of necessary proteins from their cytoplasm at the point of use.Introduction Lag screw insertion into the ideal position is essential to obtain good results in open reduction and internal fixation for femoral trochanteric fracture. Tip-apex distance (TAD) is a widely adopted method for evaluating the risk of lag screw cut-out. Adaptive positioning technology (ADAPT) is a fluoroscopic computer-assisted surgery system that enables orthopaedic surgeons to guide the screw into a proper position intraoperatively. A randomized control study concluded that ADAPT resulted in excellent TAD. However, it was not significantly better than conventional methods when performed by fellowship-trained traumatologists. Therefore, we hypothesised that ADAPT would be useful to orthopaedic residents and evaluated this usefulness. Methods We reviewed 102 patients who underwent open reduction and internal fixation for femoral trochanteric fracture from May 2017 to March 2019 using Gamma-3 intertrochanteric nails. Two residents performed all procedures; 51 patients underwent surgery using ADAPT autiously because skill or experience may influence its use, especially by orthopaedic residents.Background & aims The heterodimeric integrin receptor α4β7 regulates CD4 T cell recruitment to inflamed tissues, but its role in the pathogenesis of nonalcoholic steatohepatitis (NASH) is unknown. Here we examined the role of α4β7-mediated recruitment of CD4 T cells to the intestine and liver in NASH. Methods Male littermate F11r+/+ (control) and junctional adhesion molecule A knockout F11r-/- mice were fed a normal diet or a Western diet (WD) for eight weeks. Liver and intestinal tissues were analyzed by histology, qRT-PCR, 16s rRNA sequencing and flow cytometry. Colonic mucosa-associated microbiota was analyzed using 16s rRNA sequencing. Liver biopsies from NASH patients were analyzed by confocal imaging and qRT-PCR. Results WD-fed knockout mice developed NASH and had increased hepatic and intestinal α4β7+ CD4 T cells relative to control mice which developed mild hepatic steatosis. The increase in α4β7+ CD4 T cells was associated with markedly higher expression of the α4β7 ligand mucosal addressin cell adhed despite its growing incidence no therapies currently exist to halt NAFLD progression. Here, we show that blocking integrin receptor α4β7-mediated recruitment of CD4 T cells to the intestine and liver not only attenuates hepatic inflammation and fibrosis, but also improves metabolic derangements associated with NASH. These findings provide evidence for potential therapeutic application of α4β7 antibody in the treatment of human NASH.
