The early nephropathy in obese, diabetic, dyslipidemic (ZS) rats is characterized by tubular lipid accumulation and pervasive inflammation, two critically interrelated events. We now tested the hypothesis that proximal tubules from ZS obese diabetic rats in vivo, and proximal tubule cells (NRK52E) exposed to oxidized LDL (oxLDL) in vitro, change their normally quiescent epithelial phenotype int...
Chronic obstructive pulmonary disease (COPD) is a global health problem. Being a progressive disease characterized by inflammation and predominantly caused by tobacco smoking, it deteriorates pulmonary and skeletal muscle functioning, and reduces physical behavior, societal participation and quality of life. During the last two decades studies were focused on the airway and systemic inflammatio...
PURPOSE To investigate the effect of antioxidants and immunosuppresants on mixed peripheral blood mononuclear cells (PBMC) - chemically injured keratocytes reaction (MLKR). METHODS The PBMC stimulation assay was performed using chemically injured keratocytes treated with 0.05 N NaOH for 90 s (MLKR). MLKR were treated with various drugs including rapamycin, dexamethasone, mycophenoleic acid (M...
Melanoma is a cancer that is associated with a high capacity of invasion. Oxidative stress is recognized as cancer growth and progression. The phytochemical pigments of natural products show either anti-oxidant or pro-oxidant activity from the redox system. In addition, the phytophenolics also prevent cancer cell proliferation and progression. Objective: This study aims to investigate the effec...
The colonic lumen is likely to contain oxidants derived from unabsorbed dietary materials including transition metals, rancid fat, drugs and bacterial metabolites. The present study looks at the effect of luminal exposure of different oxidants on colonic mucosal lipid peroxidation and absorptive function. All the oxidants tested induced fluid and electrolyte secretion and indomethacin, a prosta...
We recently reported that the over-expression of skin fibroblast-derived neutral endopeptidase (NEP) plays a pivotal role in impairing the three-dimensional architecture of dermal elastic fibers during the biological mechanism of ultraviolet (UV)-induced skin wrinkling. In that process, a UVB-associated epithelial-mesenchymal cytokine interaction as well as a direct UVA-induced cellular stimula...
Parkinson`s disease (PD) is the second most common neurodegenerative disorder after Alzheimer`s disease. It is a chronic and progressive disease, and mostly afflicts elderlies. PD starts with sudden onsets and the exact cause of the disease is still unknown, however there are some early symptoms that can help us to diagnose the disease and ameliorate its effects. PD is a multi-factorial disease...
Background: Aging is a process caused by oxidants and aging-related enzymes. Therefore, the inhibition of these processes can exacerbate anti-aging agents. This study aimed to evaluate antioxidant activities leaf extracts from seven herbs used in traditional Thai herbal remedies. Methods: Researchers assessed total levels phenolic content (TPC), antioxidant, anti-collagenase, anti-tyrosinase ac...
Aging is a physiological, non-pathological process that occurs mainly as slow, gradual, and passive procedure influenced by interplay of numerous genetic environmental influences. Different ways have been tried to postponement aging extent life span in animals, dietary anti-oxidants are one them. Depending on the metabolic free radical theories aging, this work was carried out evaluate use vita...
در مواردی سیستم ایمنی بدن باعث بروز بیماریهای ایمنی مانند آنمی همولتیک نوزادان hdn می شود. تنها راه پیشگیری ایزوایمونیزاسیون rh ، ،تجویز پارتابولین (anti-d) به مادران rh منفی بعد از تولد نوزاد rh مثبت می باشد. پیشگیری از آلوایمونیزاسیون ناشی از ترانسفوزیون و درمان itp از دیگر اندیکاسیونهای تجویز anti-d می باشد. روش acid elution برای شناسایی میزان fmh جهت تصحی...
