Alpha lipoic acid (ALA), which is an anti-oxidant acting as a scavenger for reactive oxygen species, is especially used to improve glycemic control and prevent polyneuropathies associated with diabetes mellitus. ALA is considered to be a safe drug and intoxication with ALA is extremely rare. However, this paper reports a 38-year-old young woman who was admitted to the emergency department after she had ingested ten pills of 600 mg ALA belonging to her diabetic parent, which led to delirium, metabolic acidosis, thrombocytopenia, and rhabdomyolysis. To the best of our knowledge, there are only four cases of ALA intoxication reported in the literature and all were observed in children. This report aims to present the first case of ALA related intoxication worldwide in an adult patient. 相似文献

Estrogens exert a protective effect against hepatic steatosis and fibrosis. Loss of estrogen receptor-alpha (ER-α) in the liver is associated with hepatic steatosis and inflammation in animal models. We conducted a study in order to investigate the presence and extent of ER-α expression in HCV infection, and its relationship with histological and biochemical findings. Ninety biopsy-proven chronic hepatitis C (CHC) patients were enrolled in the study. Liver biopsy specimens were immunohistochemically stained for ER-α expression. Nuclear ER-α expression percentage was calculated. ER-α was positive in 69 of the patients (76%). ER-α positive and negative groups were not significantly different in terms of age, gender, necroinflammatory activity, fibrosis, steatosis, serum levels of AST, ALT, ALP, GGT, and bilirubin. ER-α expression percentage was not correlated with fibrosis, steatosis, necroinflammatory activity and biochemical findings. Although estrogens are known to be protective against fibrosis and steatosis in animal models, we did not find any significant correlation between ER-α expression and histopathological and biochemical findings in CHC patients. These findings should be verified in further large scale studies. 相似文献

Background
Cancer cachexia is a devastating condition leading to loss of function and independence, decreased performance status, decreased quality of life, and poor prognosis. Adipokines play a role in a wide variety of physiological or pathological processes, including immunity and inflammation, in addition to having significant effects on metabolism and lipogenesis. The objective of the present study was to investigate the relationship of adipokines and systemic inflammation in weight-losing advanced-stage non-small-cell lung cancer (NSCLC) patients. 相似文献5.

Introduction: Gestational diabetes mellitus (GDM) occurs in ~10–25% of pregnancies. Nesfatin-1, plays a role in carbohydrate metabolism by inhibiting glucagon secretion, besides has a glucose-dependent insulinotropic effect. Explanation of the GDM pathogenesis is important due to preventing gestational complications. We aimed to investigate relationship between GDM and Nesfatin-1.Material and methods: Seventy-nine pregnant subjects were randomly allocated to either GDM group (GDG, n?=?38) or control group (CG, n?=?41). For GDM diagnosis, 50 and 100?g oral glucose tolerance test (OGTT) were used. Nesfatin-1, insulin and other parameters were measured for all subjects. The homeostasis model assessment-insulin resistance (HOMA-IR) was calculated.Results: Nesfatin-1 was found lower and insulin was found higher in GDG than CG. Negative correlation has been founded between Nesfatin-1 with weight, BMI, fasting glucose, serum glucose level at first hour of the 50?g OGTT and HOMA-IR.Conclusion: In this study, patients with GDM had lower Nesfatin-1 levels than without GDM. Therefore, when the Nesfatin-1 effects on the GDM pathogenesis is clear, it may be contributed to diagnosis and treatment of the GDM. 相似文献

Nanoparticulate systems have been receiving a significant attention especially for the treatment of cancer but one of the main hurdles is to produce these developed and high-tech nanosystems in large quantities. Anticancer drug formulations are generally designed for parenteral administrations but oral administration is still the most convenient route. In this study, orally applicable nano-sized chitosan nanoparticles (NPs) were successfully prepared using Nano Spray Dryer. It is possible to produce these NPs in large quantities by simply increasing the processing time using the machine without changing any parameter. A chemotherapeutic agent (imatinib mesylate; IMA) and nonsteroidal anti-inflammatory drug (dexketoprofen trometamol) were loaded together in these NPs. NPs were also functionalized with polyethylene glycol and folic acid to obtain long circulating NPs and tumor targeting. The antitumoral activities of formulations showed that these developed NPs can enhance the effectiveness. Animal experiments were performed on fibrosarcoma-bearing mice model, and the treatment with 0.8 mg/μL/kg IMA-loaded chitosan NPs was found to be successful to slow down the growth of tumors. The tumor tissues were removed from the animals and enzymatic activities were evaluated. The inhibitory effect of tyrosine kinase was found to be enhanced from 36.4% to 68.4% when IMA was used in combination with dexketoprofen trometamol. Furthermore, all dried NPs were found to be stable for more than a year at 25°C. Presented results show that these developed combinatorial drug–loaded NPs can be used for the treatment of fibrosarcoma, and these data can provide an insight, new strategies for productions or alternatives in cancer treatment. 相似文献

Fc receptors (FcR) play an important role in immune regulation. This might be linked to the variability in immune response, therefore relating to the pathogenesis of atopic diseases. The aim of the present study was to evaluate the Fc γ RIIIa gene polymorphism in Turkish children with asthma and allergic rhinitis. The study included 364 atopic children (184 bronchial asthma, 180 allergic rhinitis) and 234 healthy subjects as the control group, aged between 5 to 16 years. Patients were recruited from outpatient clinics of allergy and general pediatric care. Plasma IgE concentrations were measured by immunoassays and skin prick test was done in children with atopic diseases. The Fc γ RIIIa gene polymorphism was determined using the polymerase chain reaction method. Distribution of V158V genotype was significantly different among patient groups compared to controls (for asthmatic children OR: 5.33, 95% CI: 2.80–10.23, p < 0.001; for allergic rhinitis OR: 3.25, 95% CI: 1.75–6.07, p = 0.001). Distribution of 158 V allele was significantly different among asthmatic children (OR: 2.20, 95% CI: 1.65–2.92, p < 0.001) and allergic rhinitis patients (OR: 1.77, 95% CI: 1.32–2.35, p < 0.001) compared to healthy controls. Our study shows that the V158V genotype in Fc γ RIIIa gene polymorphism may be a genetic risk factor for the development of atopic diseases. 相似文献
