Inhibition of fatty acid amide hydrolase (FAAH) reduces the gastrointestinal damage produced by non-steroidal anti-inflammatory agents such as sulindac and indomethacin in experimental animals, suggesting that a dual-action FAAH-cyclooxygenase (COX) inhibitor could have useful therapeutic properties. Here, we have investigated 12 novel amide analogues of ibuprofen as potential dual-action FAAH/COX inhibitors. N-(3-Bromopyridin-2-yl)-2-(4-isobutylphenyl)propanamide (Ibu-AM68) was found to inhibit the hydrolysis of [3H]anandamide by rat brain homogenates by a reversible, mixed-type mechanism of inhibition with a Ki value of 0.26 µM and an α value of 4.9. At a concentration of 10 µM, the compound did not inhibit the cyclooxygenation of arachidonic acid by either ovine COX-1 or human recombinant COX-2. However, this concentration of Ibu-AM68 greatly reduced the ability of the COX-2 to catalyse the cyclooxygenation of the endocannabinoid 2-arachidonoylglycerol. It is concluded that Ibu-AM68 is a dual-acting FAAH/substrate-selective COX inhibitor.Bioactive compounds, synthesized by photosynthetic microorganisms, have drawn the attention of the pharmaceutical field. This study aimed at evaluating synthesis and in vitro antioxidant capacity of phenolic compounds produced by a microalgae species P. boryanum, which was grown in six different culture media (standard BG11, modified BG11/MBG11, standard WC, modified WC, WC*2 and basal). The highest concentrations of biomass (1.75 ± 0.01 g.L-1) and phenolic content (3.18 ± 0.00 mg.g-1) were obtained when P. boryanum was grown in MBG11 and phenolic acids were identified gallic, protocatechuic, chlorogenic, hydroxybenzoic and vanillic ones. All extracts exhibited scavenger activity in the ABTS assay and inhibited peroxidase. However, phenolic compounds from P. boryanum grown in BG11 and MBG11 had the most potent scavenger activity in the DPPH assay. In sum, P. boryanum can be a new source of free phenolic compounds with potential antioxidant activity when grown in MBG11, since it yields high amounts of biomass and phenolic compounds.Chronic otitis media is a major contributor to acquired hearing loss in developing countries. Developing countries such as India, with huge populations and poor health infrastructures, have always felt the shortage of trained specialists who can provide quality care to meet the enormous demand for treatment of this disease. This pilot study assessed the feasibility of empowering trained health workers equipped with ENTraview, a store-and-forward telemedicine device that integrates a camera- enabled smart phone with an otoscope. This device allows the screening of otology patients within the community. Three months of extensive training was provided to five community health workers on primary ear and hearing care, including training on the use of the ENTraview device. Community otology screenings were conducted to triage otology patients and provide them with specialized ENT care at a tertiary hospital. In the initial 6 months of the project, 45 screening camps were organized, which screened 3,000 patients free of cost. Of these 3,000 screened patients, 54% (1,619) were referred for ENT consultation and 215 patients reported. Nearly 50% (103) of the 215 reporting patients required surgical intervention, and 29 patients underwent surgery. Reaching out to the community by remote screening of ear diseases by trained technicians with a telemedicine device seems to be an effective and cost-effective way to triage patients with otologic pathologies.Background Branched-chain amino acids (BCAAs), essential nutrients including leucine, isoleucine and valine, serve as a resource for energy production and the regulator of important nutrient and metabolic signals. Recent studies have suggested that dysfunction of BCAA catabolism is associated with a risk of cardiovascular disease. Platelets play an important role in cardiovascular disease, but the functions of BCAA catabolism in platelets remain unknown. Methods The activity of human platelets from healthy subjects before and after ingestion of BCAAs were measured. Protein phosphatase 2Cm (PP2Cm) specifically dephosphorylates branched-chain α-keto acid dehydrogenase, and thereby activates BCAA catabolism. PP2Cm deficient mice were used to elucidate the impacts of BCAA catabolism on platelet activation and thrombus formation. Results We found that ingestion of BCAAs significantly promoted human platelet activity (n=5, P less then 0.001) and arterial thrombosis formation in mice (n=9, P less then 0.05). We alsotated platelet activation and thrombosis formation. Additionally, the increased levels of BCAAs and the expression of positive regulators of BCAA catabolism in platelets from type 2 diabetes mellitus patients are significantly correlated with platelet hyperreactivity. Lowering dietary BCAA intake significantly reduced platelet activity in ob/ob mice (n=4, P less then 0.05). Conclusions BCAA catabolism is an important regulator of platelet activation and is associated with arterial thrombosis risk. Targeting the BCAA catabolism pathway or lowering dietary BCAA intake may serve as a novel therapeutic strategy for metabolic syndrome-associated thrombophilia.Rosmarinic acid, a phytochemical compound, bears diverse pharmaceutical profile. It is composed by two building blocks caffeic acid and a salvianic acid unit. The interaction profile, responsible for the delivery of rosmarinic acid and its two substructure components by serum albumin remains unexplored. To unveil this, we established a novel low-cost and efficient method to produce salvianic acid from the parent compound. To probe the interaction profile of rosmarinic acid and its two substructure constituents with the different serum albumin binding sites we utilised fluorescence spectroscopy and competitive saturation transfer difference NMR experiments. These studies were complemented with transfer NOESY NMR experiments. The thermodynamics of the binding profile of rosmarinic acid and its substructures were addressed using isothermal titration calorimetry. In silico docking studies, driven by the experimental data, have been used to deliver further atomic details on the binding mode of rosmarinic acid and its structural components.The aim of this study was to evaluate the effect of acceleration on the external and internal load during repeated sprint exercises (RSE). This study used a cross-over design. Sixteen soccer players were included (mean ± SDs age 21 ± 1 years; weight 71.1 ± 7.7 kg). RSE was 3 sets of 7 × 30 m sprints with 25 s and 3 min recovery between sprints and sets, respectively. RSE was performed using two protocols requiring either 10 m maximal acceleration (2.12 m.s-2 [RSE-MA]) or 10 m submaximal acceleration (1.66 m.s-2 [RSE-SA]). Global positioning systems (10 Hz; STATSports, Viper) were utilized to collect high speed running (HSR), dynamic stress load (DSL), Heart Rate (HR) peak, time >85% HR peak, respiratory (RPEres) and muscular (RPEmus) rating of perceived exertion. RSE-MA induced higher load than RSE-SA in HSR (p = 0.037, ES = 0.20), DSL (p = 0.027, ES = 0.43), HR peak (p = 0.025, ES = 0.47), Time >85% HR peak (p = 0.028, ES = 1.11), RPEres (p = 0.001, ES = 1.10), and RPEmus (p = 0.001, ES = 0.73). This study shows that a different acceleration intensity in a RSE (MA vs. SA) impacts external and internal training load parameters.One challenge faced by teachers of phonetics, speech science, and clinical speech disorders courses is providing meaningful instruction that closes the theory to practice gap. One barrier to providing this type of deep learning experience is the lack of publicly available examples of speech recordings that illustrate comparisons between typical and disordered speech production across a broad range of disorder populations. Data of this type exist, but are typically collected for specific research projects under narrowly written IRB protocols that do not allow for release of even de-identified speech recordings to other investigators or teachers. As a partial corrective to this problem, we have developed an approved publicly available database of speech recordings that provides illustrative examples of adult and child speech production from individuals with and without speech disorders. The recorded speech materials were designed to illustrate important clinical concepts, and the recordings were collected under controlled conditions using high-quality equipment. The ultimate goal of creating this corpus is to improve practitioners' and scientists' understanding of the scientific bases of knowledge in our profession and improve our ability to develop clinical scientists and young researchers in the field.Functional fermentable fibers are considered essential for a healthy diet. Recently, we demonstrated that gut microbiota dysbiotic mice fed an inulin-containing diet (ICD) developed hepatocellular carcinoma (HCC) within 6 months. In particular, a subset of toll-like receptor 5-deficient (T5KO) mice prone to HCC exhibited rapid onset of hyperbilirubinemia (HB) and cholemia; these symptoms provide rationale that ICD induces cholestasis. Our objective in the current study was to determine whether inulin-fed T5KO-HB mice exhibit other known consequences of cholestasis, including essential fatty acid and fat-soluble vitamin deficiencies. Here, we measured hepatic fatty acids and serum vitamin A and D levels from WT, T5KO low bilirubin (LB) and T5KO-HB mice fed ICD for 4 weeks. Additionally, hepatic RNAseq and proteomics were performed to ascertain other metabolic alterations. SU6656 Compared to WT and T5KO-LB, T5KO-HB mice exhibited steatorrhea, i.e. ~50% increase in fecal lipids. This could contribute to the significant reduction of linoleate in hepatic neutral lipids in T5KO-HB mice. Alongside, serum vitamins A and D were ~50% reduced in T5KO-HB mice, which was associated with metabolic compromises. Overall, our study highlights that fermentable fiber-induced cholestasis is further characterized by depletion of macro and micronutrients.INTRODUCTION Brain drain, an increasing phenomenon, can be defined as the international transfer of resources, in the form of a highly educated workforce, from developing to more developed countries. The tendency for migration leads to the activation of informational behaviour. The aim of this study was to search for the main causes of emigration of Greek medical doctors while their country suffers from an economic crisis. METHODS A cross-sectional study using a quantitative sampling method in the form of questionnaires was performed. These questionnaires were answered by 143 doctors working in the National Health System in the city of Ioannina in north-western Greece. Correlations between the examined parameters and predictive factors of immigration trend were recorded. RESULTS A total of 85% of the respondents were dissatisfied with their wage, only 30% were sure that they would keep their current job and nearly 52% of them answered negatively to questions regarding their professional development. Only 33% of the physicians were negatively disposed towards moving abroad. Most of them were permanent personnel. Unsatisfactory wages, job uncertainty, non-permanent working status and low professional development opportunities were correlated with the phenomenon of immigration (all p less then 0.001). In the multivariate binary logistic regression analysis, lower wage (odds ratio (OR)=0.66, 95% confidence interval (CI)=0.453-0.961, p=0.03) and job uncertainty (OR=1.355, 95%CI=1.040-1.767, p=0.025) were independent predictors of the immigration trend. CONCLUSION The tendency of Greek medical doctors to emigrate is strongly related to financial dissatisfaction, professional insecurity and minimal development opportunities. Especially in rural areas these high immigration trends can result in a shortage of GPs. The need for emigration is less common among qualified doctors with permanent contracts.
