In AKR1B10-KO hepatocytes, GA, GL, and hydrolysates of GL had no regulatory effect on retinol metabolism. Therefore, GA, the active metabolite of GL, as a novel AKR1B10 inhibitor, could promote retinoic acid synthesis. GL restored the balance of retinol metabolism in NAFLD/NASH mice by metabolizing to GA.Oxidative stress-induced Ca2+ permeable transient receptor potential melastatin 2 (TRPM2) channels are expressed at high levels in the brain, appear to link neuronal excitability to cellular metabolism, and are involved in the pathogenesis of neurodegenerative disorders. We aimed to study the electrophysiological properties of TRPM2 channels in stellate cells of the mouse ventral cochlear nucleus (VCN) using molecular, immunohistochemical and electrophysiological approaches. click here In the present study, the real time PCR analysis revealed the presence of the TRPM2 mRNA in the mouse VCN tissue. Cell bodies of stellate cells were moderately labeled with TRPM2 antibodies using immunohistochemical staining. Stellate cells were sensitive to intracellular ADP-ribose (ADPR), a TRPM2 agonist. Upon the application of ADPR, the resting membrane potential of the stellate cells was significantly depolarized, shifting from -61.2 ± 0.9 mV to -57.0 ± 0.8 mV (P less then 0.001; n = 21), and the firing rate significantly increased (P less then 0.001, n = 6). When the pipette solution contained ADPR (300 μM) and the TRPM2 antagonists flufenamic acid (FFA) (100 μM), N-(p-amylcinnamoyl) anthranilic acid (ACA) (50 μM) and 8-bromo-cADP-Ribose (8-Br-cADPR) (50 μM), the membrane potential shifted in a hyperpolarizing direction. ADPR did not significantly change the resting membrane potential and action potential firing rate of stellate cells from TRPM2-/- mice. In conclusion, the results obtained using these molecular, immunohistochemical and electrophysiological approaches reveal the expression of functional TRPM2 channels in stellate neurons of the mouse VCN. TRPM2 might exert a significant modulatory effect on setting the level of resting excitability.The performance of transforaminal endoscopic lumbar interbody fusion through a Kambin's triangle approach requires significant modifications when compared to a traditional transforaminal discectomy. Indeed, due to the inherently limited field of view, small working corridor, and need to deploy an adequately sized interbody graft, there are several important technical adaptations which can help improve the efficacy of this approach. In this manuscript, the technical aspects of a percutaneous, endoscopic interbody fusion are discussed in detail.Immobilization of microorganisms capable of degrading specific contaminants significantly promotes bioremediation processes. In this study, innovative and ecofriendly biosorbent-biodegrading biofilms have been developed in order to remediate oil-contaminated water. This was achieved by immobilizing hydrocarbon-degrading gammaproteobacteria and actinobacteria on biodegradable oil-adsorbing carriers, based on polylactic acid and polycaprolactone electrospun membranes. High capacities for adhesion and proliferation of bacterial cells were observed by scanning electron microscopy. The bioremediation efficiency of the systems, tested on crude oil and quantified by gas chromatography, showed that immobilization increased hydrocarbon biodegradation by up to 23 % compared with free living bacteria. The resulting biosorbent biodegrading biofilms simultaneously adsorbed 100 % of spilled oil and biodegraded more than 66 % over 10 days, with limited environmental dispersion of cells. Biofilm-mediated bioremediation, using eco-friendly supports, is a low-cost, low-impact, versatile tool for bioremediation of aquatic systems.Functionalized neurotube are a third-generation of conduits with chemical or architectural bioactivity developed for axonal proliferation. The goal of this review is to provide a synopsis of the functionalized nerve conduits described in the liter
