BACKGROUND Methanol toxicity poses a significant public health problem in developing countries, and in Southeast Asia, where the most common source of poisoning is via adulterated liquor in local drinks. Methanol toxicity can have devastating visual consequences and retinal specialists should be aware of the features of this toxic optic neuropathy. The authors report a case of severe systemic m...
Background: Acute methanol poisoning is one of the most important chemical poisoning due to drinking of illegal and handmade alcoholic beverages in Iran. The aim of this study was to evaluate clinical and biochemical parameters as prognostic factor in acute methanol poisoning. Methods: A retrospective study was performed on acute methanol poisoning cases admitted to the Loghman Hakim Hospital P...
Trade-offs between selected and nonselected environments are often assumed to exist during adaptation. This phenomenon is prevalent in microbial metabolism, where many organisms have come to specialize on a narrow breadth of substrates. One well-studied example is methylotrophic bacteria that can use single-carbon (C(1)) compounds as their sole source of carbon and energy, but generally use few...
Methanol poisoning is a relatively rare but potentially serious medical emergency. Toxicity results when methanol is successively oxidized to the active metabolites formaldehyde and formic acid. We report a case of a 23-year-old male, a high daily alcohol consumer, who attended the local primary health care centre complaining of sudden visual loss. A presumed diagnosis of methanol intoxication ...
In this study the effect of cryoprotectants that have been shown to be the least toxic to zebrafish ovarian follicles (methanol and Me(2)SO), on mitochondria of stage III ovarian follicles was evaluated. The mitochondrial distributional arrangement, mitochondrial membrane potential, mtDNA copy number, ATP levels and ADP/ATP ratios were assessed following exposure to cryoprotectants for 30 min a...
در این پروژه فیلترهای مایکرواستریپ جدیدی برای بهدست آوردن اندازهی فشرده، پاسخ تیز و نیز باند قطع عریض ارائه شده است که از جملهی آن ها فیلتری است که از سری شدن یک رزوناتور شاخهای منتهی به نیمدایره و یک تکهی شعاعی بهبود یافته به عنوان تضعیف کنندهی هارمونیک، تشکیل شده است. فرکانس قطع -3 db این فیلتر در 1.54 ghz قرار دارد. باند گذر این فیلتر تنها 0.26 ghz است که شامل محدودهی فرکانسی 1.5...
Active and durable electrocatalysts for methanol oxidation reaction are of critical importance to the commercial viability of direct methanol fuel cell technology. Unfortunately, current methanol oxidation electrocatalysts fall far short of expectations and suffer from rapid activity degradation. Here we report platinum-nickel hydroxide-graphene ternary hybrids as a possible solution to this lo...
assigning premium to the insurance contract in iran mostly has based on some old rules have been authorized by government, in such a situation predicting premium by analyzing database and it’s characteristics will be definitely such a big mistake. therefore the most beneficial information one can gathered from these data is the amount of loss happens during one contract to predicting insurance ...
BACKGROUND The search for new antimalarial drugs has become increasingly urgent due to plasmodial resistance to existing drugs. As part of this global effort, the present study aimed at evaluating the antimalarial activity of two traditionally used medicinal plants against the disease. METHODS Acute toxicity and four-day suppressive effects of aqueous, methanol and chloroform extracts of the ...
