Acute kidney injury (AKI) is a common life-threatening complication. In this study, β-amyrin is hypothesized to exert a potential nephroprotective effect against glycerol-induced nephrotoxicity in rats. Thirty-two female Sprague-Dawley rats were divided into four groups normal control, β-amyrin treated (50 mg kg-1 body weight) for 14 days, glycerol 25% (10 ml kg-1 BW volume/volume in sterile saline, intramuscular), and β-amyrin + glycerol-treated rats. Assessing kidney function was done through the measurement of serum urea and creatinine (SCr). Real-time quantitative polymerase chain reaction analysis was done to measure the changes in the gap junction protein and intermediate filament proteins (IFPs) messenger RNA (mRNA) levels. Renal tissue histopathology was also observed. Glycerol exhibited significant elevation in the SCr and urea with significant upregulation of connexin43, vimentin, and nestin. The levels of all disrupted parameters were improved by the pre-administration of β-amyrin. The β-amyrin exerts significant improvement of the biochemical parameters with a restoration of the renal tissue histopathological picture. Significant downregulation of the expression levels of the gap junction protein and IFPs mRNA was also seen. Collectively, the administration of β-amyrin showed a promising effect for a protection against glycerol-induced AKI in rats.Introduction Endometriosis is a chronic painful condition characterized by high prognostic uncertainty, as well as the threat of infertility and emotional symptoms that may affect many aspects of women, including psychological characteristics like dispositional optimism. Considering the impact of endometriosis on psychological health and the paucity of papers on this topic, the aim of this study is to explore optimism and associated factors in endometriosis.Methods A case-control study was performed on a group of 95 women with endometriosis and 156 controls. All participants completed the Life Orientation Test-Revised (LOT-R), a self-administered tool for assessing dispositional optimism. Pain severity, medication, gynecological and socio-demographic information was also collected.Results Low optimism was observed for women with endometriosis compared to controls even after covariate adjustment (LOT-R global scores 14.5 vs. 15.9 points, p = .045).Conclusions This study provides the first evidence that a personality dimension with many prognostic implications may be altered in women with endometriosis. Our findings highlight the importance of a broader understanding of this condition, treating this disorder from a biopsychosocial perspective and suggests the need for non-medical attention within a multidisciplinary team.Objective The aim of this study was to explore the "Birth Attitude Profile Scale (BAPS)" in a selected sample of women with fear of birth. Another aim was to develop profiles of women according to their birth attitudes and levels of childbirth fear in relation to background characteristics.Methods A secondary analysis of data collected in two different samples of women with fear of birth. Data were collected by a questionnaire in gestational week 36 and background data from mid-pregnancy. A principal component analysis and a cluster analysis were performed of the combined sample of 195 women.Results The principal component analysis revealed four domains of the BAPS "personal impact, birth as a natural event, freedom of choice and safety concerns". When adding the fear of birth scale, two clusters were identified one with strong attitudes and lower fear, labeled "self-determiners"; and one with no strong attitudes but high levels of fear, labeled "fearful." Women in the "Fearful" cluster more often reported previous and current mental health problems, which were the main difference between the clusters.Conclusion The BAPS instrument seems to be useful in identifying birth attitudes in women with fear of birth and could be a basis for discussions and birth planning during pregnancy. Mental health problems were the main difference in cluster membership; therefore, it is important to ask women with fear of childbirth about physical, mental and social aspects of health. In addition, a qualitative approach using techniques such as focus groups or interviews is needed to explore how women come to form their attitudes and beliefs about birth.Background We sought to systematically review the literature and perform a meta-analysis by assessing the prevalence of human metapneumovirus (hMPV) infections from a number of studies conducted in Iran. Methods Entire studies addressing epidemiology of hMPV in Iran using data from PubMed, Scopus, Science Direct, Web of science, Google Scholar, Embase, and national Persian databases up to June 2019 were included. Results The estimated prevalence of hMPV was 8.9% (95% CI 5.4-14.2) in different regions in Iran. Compared to the global rate, in Iran hMPV infection presented an intermediate prevalence rate. The majority of hMPV positive patients were pediatric populations with pooled prevalence of 7.6% (I2 = 95%, 95% CI 3.5-15.6). Conclusion This first comprehensive review covering researches over the last 11 years expanded our knowledge about hMPV circulating in Iran. Future large epidemiological studies are needed for the evaluation of hMPV prevalence and genotype distribution in different unanalyzed regions in Iran.Excitotoxicity is the presence of excessive glutamate, which is normally taken up by glutamate transporters on astrocytes. Glutamate transporter 1 (GLT-1) is the major transporter on glia cells clearing more than 90% of the glutamate. Sirtuin 4 (SIRT4) is a mitochondrial sirtuin which is expressed in the brain. Previously, it was shown that loss of SIRT4 leads to a more severe reaction to kainic acid, an excitotoxic agent, and also decreased GLT-1 expression in the brain. In this study, we aimed to investigate whether overexpression of SIRT4 is protective against excitotoxicity in glia cells. We overexpressed SIRT4 in A172 glioma cell line and treated with kainic acid in order to induce excitotoxicity. We observed that SIRT4 overexpression increased the cell viability after kainic acid treatment. In addition, reduced glutamate was detected in glutamate assay with overexpression of SIRT4 after kainic acid treatment since SIRT4 decreased cell death by preventing excitotoxicity. Our results show that overexpression of SIRT4 increased the protein levels of GLT-1 and glutamate dehydrogenase (GDH) after kainic acid (KA) treatment so that excess glutamate can be absorbed. However, overexpression of SIRT4 decreased glutamine synthetase (GS) levels. These results demonstrate that, by inhibiting GS, SIRT4 prevents glutamine formation, which will be converted to glutamate in neurons. SIRT4 prevents excitotoxicity via upregulating glutamate metabolism. Finally, our results may show that SIRT4 might prevent excitotoxicity and related cell death via reducing GS expression and upregulating GLT-1 and GDH levels. Therefore, it is important to develop therapeutics against excitotoxicity through SIRT4-related pathways in the cell.Objectives Brain-Derived Neurotrophic Factor (BDNF) has been associated with alcohol dependence and appear to vary after withdrawal, although the link with the withdrawal outcome on the long term is unknown.We aimed to assess the evolution of BDNF levels during the six months following withdrawal and determine the association with the status of alcohol consumption.Methods Serum BDNF levels of alcohol-dependent patients (n = 248) and biological and clinical parameters were determined at the time of alcohol cessation (D0), 14 days (D14), 28 days (D28), and 2, 4, and 6 months after (M2, M4, M6).Results Abstinence decreased during follow-up and was 31.9% after six months. BDNF levels increased by 14 days after withdrawal and remained elevated throughout the six-month period, independently of alcohol consumption. Serum BDNF levels evolved over time (p  less then  0.0001), with a correlation between BDNF and GGT levels. The prescription of baclofen at the time of withdrawal was associated with higher serum BDNF levels throughout the follow-up and that of anti-inflammatory drugs with lower BDNF levels.Conclusions A link between BDNF levels, liver function, and the inflammatory state in the context of alcohol abuse and not only with alcohol dependence itself is proposed.The University of South Florida, College of Public Health, is dedicated to providing career planning and professional development services for students in varying formats. However, changing public health training needs and an emerging need for focused attention on professional development necessitated the development of an evaluative program to better understand our students' needs in these areas. Specifically, anecdotal student feedback about feeling unprepared professionally and survey feedback from students, preceptor feedback regarding the need for students to be better trained in core professional concepts, and low rates of attendance in standard professional development events resulted in a quality improvement study to identify students' perceived career planning and professional development needs. Findings were used to redesign current services and provided the basis for developing more targeted trainings to ensure that public health graduates are better prepared to meet employer expectations and to excel in the workforce. This article provides an overview of this transformative process, including the results of the qualitative survey on student, faculty, alumni, and community preceptor perspectives, and resulting prototypes developed for the professional development pilot along with preliminary insights.Objectives Attenuation of brain-derived neurotrophic factor (BDNF) availability as well as increased dipeptidyl peptidase-4 (DPP4) activity have both been reported to link to the pathogenesis of depression. The aim of this study was to test the correlation between depressive symptoms and plasma DPP4 activity to BDNF ratio (DBR).Methods We evaluated DPP4 activity, BDNF, oxidative stress parameters, inflammatory markers and calculated DBR in a cross-sectional sample of 1640 nondiabetic participants.Results DPP4 activity was negatively related to BDNF in participants with and without depressive symptoms (r=-0.351 and r=-0.404, P  less then  0.001). Nitrotyrosine and 8-iso-PGF2a mediated 18.4% and 12.6% of the total effect of DPP4 activity on BDNF, respectively. 8-iso-PGF2a, nitrotyrosine, C-reactive protein, interleukin-6 and PHQ-9 score progressively increased across DBR quartiles. Participants whose DBR were in the highest quartile had 2.64-fold increased odds (OR =3.03) of depressive symptoms. The depressive symptoms risk increased more with lower levels of BDNF and higher levels of DPP4 activity (P less then 0.05).Conclusions Our data suggested inverse correlation between DPP4 activity and BDNF through the oxidative stress mediator. The positive relationship between DBR and depressive symptoms risk raise feasibility of identifying DBR as a novel biological marker or even a possible therapeutic target for depression.Overdose of acetaminophen (APAP) is the main reason for acute liver failure. Oxidative stress is associated with hepatotoxicity caused by APAP. Betaine is a methyl donor and S-adenosylmethionine precursor. The present study investigated the effect of betaine and the role of nuclear factor-erythroid-2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) genes in hepatotoxicity induced by APAP in mice. In this study, male Naval Medical Research Institute (NMRI) mice were treated with 500 mg/kg of betaine for 5 days followed with a single dose of APAP 300 mg/kg on the fifth day. Biochemical, histological, immunohistochemical, Western blot, and real-time polymerase chain reaction (PCR) analyses were then conducted. The results of the present study showed that betaine pretreatment improved hepatotoxicity through the reduction of serum ALT and AST levels and ameliorating histopathological finding. Betaine pretreatment also increased glutathione level and decreased malondialdehyde level. Importantly, the results of immunohistochemical, Western blot and real-time PCR showed that the APAP increased the expression of the genes and proteins of Nrf2 and HO-1.
