The aspect of treatment of autistic behaviour was investigated using valproic acid rat model of pregnant female rats. Two main groups (10 male rats/group) were treated for 6 days and then divided into six subgroups. The first group of normal rats was divided into three subgroups: (A) - control group, (B) - treated with camel milk (CAM; 2 mL/p.o) and (C) - treated with leptin (1000 µg/kg i.p) twice daily. The second group of autistic rats was randomly distributed into four subgroups as follows: (D) - positive control (autistics rats), (E) - treated with CAM, (F) - treated with a moderate dose of leptin and (G) - treated with a higher dose of leptin...

Indoleamine 2,3-dioxygenase (IDO), which is highly expressed in human glioblastoma and involved in tumor immune escape and resistance to chemotherapy, is clinically correlated with tumor progression and poor clinical outcomes, and is a promising therapeutic target for glioblastoma. IDO inhibitors are marginally efficacious as single-agents; therefore, combination with other therapies holds promise for cancer therapy. The aim of this study was to investigate the anti-tumor effects and mechanisms of the IDO inhibitor PCC0208009 in combination with temozolomide...

Currently, the role of cytokines in the tumor progression, including breast cancer, is universally recognized. At the same time, there are still many questions concerning the role of individual cytokines and receptors for cytokines in various morphogenetic processes underlying the tumor progression. The objective of this work was to study cytokine production and vascular endothelial growth factor (VEGF)-R2 and VEGF-R1 expression by mammary adenocarcinoma (MAC) and the correlations with histopathological parameters of malignant tumors...

Orexin-A elicits multiple potent effects on a variety of tumor cells via different signaling pathways. However, it is unknown whether it has a neuroprotective effect on SH-SY5Y human neuroblastoma cells. This study investigated the neuroprotective effect of Orexin-A against hydrogen peroxide (H2 O2 )-induced oxidative damage in SH-SY5Y cells and the underlying mechanism. H2 O2 treatment decreased the viability of SH-SY5Y cells, induced apoptosis, and decreased superoxide dismutase activity. Orexin-A attenuated these effects, indicating that it protects SH-SY5Y cells against H2 O2 -induced oxidative damage...

Common variable immunodeficiency (CVID) and immunoglobulin A deficiency (IgAD) are the most prevalent primary immunodeficiency disorders. High rates of familial inheritance have been described in CVID and IgAD, but it is unknown in different ethnic populations. We aimed to determine the prevalence of familial cases and whether they showed more severe clinical characteristics than sporadic ones in Turkish patients. A total of 40 CVID and 70 IgAD patients and their 251 first-degree relatives (FDRs) were evaluated...

LIGHT (homologous to lymphotoxins, exhibiting inducible expression, and competing with herpes simplex virus (HSV) glycoprotein D for herpes virus entry mediator (HVEM), a receptor expressed by T lymphocytes) has been involved in various autoimmune and inflammatory disorders. LIGHT induces the expression of interleukin-8 (IL-8), which is up-regulated in chronic spontaneous urticaria (CSU). To determine circulating soluble LIGHT concentration and its relationship with IL-8 concentration in patients with CSU. Concentrations of LIGHT, IL-8, and C-reactive protein (CRP) were determined in plasma or serum of CSU patients by an enzyme-linked immunosorbent assay...

Non-selective inhibitors of spleen tyrosine kinase (SYK) efficiently suppress disease in T cell-dependent models of crescentic glomerulonephritis. However, the therapeutic potential of selective SYK inhibitors in this disease has not been established. In addition, we lack knowledge regarding SYK expression in non-myeloid cells in glomerulonephritis. We addressed these two issues in a rat model of nephrotoxic serum nephritis (NTN) using a SYK inhibitor, GS-492429. Disease was induced in Sprague-Dawley rats (Study 1) or Wistar-Kyoto (WKY) rats (Study 2) by immunization with sheep IgG and administration of sheep anti-rat nephrotoxic serum...

Candidiasis is a fungal infection caused by yeasts that belong to the genus Candida. There are over 20 species of Candida yeasts that can cause infection in humans, the most common of which is Candida albicans. Candida yeasts normally reside in the intestinal tract and can be found on mucous membranes and skin without causing infection. However, under immunocompromised conditions, Candida can cause significant infections in susceptible patients. Herein, we report a peculiar presentation of a C. albicans cutaneous infection in an immunocompetent young subject...

Ultrasound (US) can reveal the presence of steatosis in non-alcoholic fatty liver disease (NAFLD), but its diagnostic accuracy to reveal signs of fibrosis is low except in advanced stages of disease (e.g. cirrhosis). Current guidelines suggest the use of clinical algorithms, such as the NAFLD fibrosis score, and elastography to predict the progression of fibrosis, and the integration of elastography improves the detection accuracy of liver stiffness. However, there is a lack of evidence about the correlation between clinical algorithms and conventional US, and elastography is limited by the relative low diffusion, necessity of training, and loss of diagnostic accuracy in patients with high body mass index (BMI), waist circumference, or increased thickness of parietal walls, with consequent significant rates of failure of measurement of liver stiffness...

Systemic lupus erythematosus (SLE; lupus) is a prototypical autoimmune disease characterized by circulating autoantibodies to nuclear antigens and immune complex deposition, resulting in damage to target organs. To investigate the effects of tacrolimus (TAC) on effector T cells and B cells, we examined its involvement in the development of effector T cells, germinal center (GC) B cells, and plasma cells in an in vitro system using wild-type (WT) and lupus-prone mice. The population of T helper (Th) 1, Th2, and Th17 cells interleukin (IL)-17-producing T (Th17) cells and the production of interferon-γ and interleukin-17A IL-17A were suppressed by TAC...

Reduced glucose utilization and deficient energy metabolism that occur in the early stages of Alzheimer's disease correlate with impaired cognition, and this information is evidence that Alzheimer's disease is a metabolic disease that is associated with brain insulin/insulin-like growth factor resistance. This research aimed to investigate the effects of Banxia Xiexin decoction (BXD) on cognitive deficits in APPswe/PS1dE9 double transgenic mice and verify the hypothesis that BXD treatment improves cognitive function via improving insulin signalling, glucose metabolism and synaptic plasticity in the hippocampus of APPswe/PS1dE9 double transgenic mice...

Our study attempted to verify the effect of lncRNA BST2 interferon-stimulated positive regulator (BISPR) on cell viability, propagation and invasiveness of thyroid papillary carcinoma (TPC) and the interactive relationship between BISPR and miR-21-5p. Microarray analyzed the aberrant expression lncRNA BISPR in TPC. BISPR and miR-21-5p as well as B-cell lymphoma-2 (Bcl-2) expressions in TPC cells were determined by quantitative polymerase chain reaction (qRT-PCR) and Western blot. Cell counting kit-8 (CCK-8) assay, dual luciferase reporter assay, and transwell assay were conducted to manifest cell viability, propagation, and invasiveness of TPC cells...

Regulation of the immune response in asthma is complex. MicroRNA-126 (miR-126) expression has been implicated in this response, so we sought to determine the clinical significance of miR-126 measured in the peripheral blood. A total of 80 children with acute asthma were selected to participate in the study and were compared to 80 healthy children. The relative circulating miR-126 levels, interleukin (IL)-4 levels, and the Th17 cell percentage in the peripheral blood of children in the case group were significantly higher than those in the control group, while the interferon (IFN)-γ levels and the CD4+ CD25+ Treg cell percentage were significantly lower than those in the control group...

Uterine fibroids (UFs) are one of the most common pathologies of the female genital tract. The incidence of UFs has been estimated at 25-80%. Tumor necrosis factor (TNF)-α is a cell-signaling protein involved in systemic inflammation and is one of the cytokines responsible for the acute phase reaction. The aim of the study was to evaluate the impact of clinically symptomatic UFs on TNF-α serum levels. A total of 149 Caucasian women were included: 85 patients admitted for surgery due to clinically symptomatic UFs (n = 85; study group) and 64 age-matched UF-free controls (n = 64)...

Macrophage migration inhibitory factor (MIF) is deemed as an immunoregulatory and proinflammatory cytokine related to the progression of tuberculosis. A CATT short tandem repeat (STR) polymorphism at position -794 in the MIF gene promoter region is associated with the susceptibility to tuberculosis (TB). To investigate whether macrophage MIF gene mif CATT variants are associated with susceptibility to retreatment cases of TB and drug-resistant TB prevalence, genotyping of MIF -794 CATT polymorphism and quantifying of serum MIF were performed to associate MIF-794 CATT polymorphism with new patients and retreatment cases...

Current scientific consensus about the physiopathology in the progression from severe sepsis to septic shock and death focuses on myocardial contractile dysfunction. Nevertheless, objective parameters to establish a pathological correlate of a fatal outcome are lacking; then a cause of death due to sepsis can remain an unsolved problem. We first reviewed all death cases recorded at our institutions during the period from 2007 until 2015. Then, we conducted a retrospective study of a selected autopsy series of people who had received "sepsis" as cause of death...
