Background and objectives: Recently, deep vein thrombosis (DVT) has remained a major cause of morbidity and death. DVT is a serious public health issue and can be complicated by pulmonary embolism and stroke leading to high economic burden. Disease etiologies may include protein C deficiency, protein S deficiency, factor V Leiden gene mutation, prothrombin gene 20210A mutation,...

Microalgae have many biotechnological applications in various industries including food and feed, fertilizer, biofuel, cosmetics, pharmaceutics, wastewater treatment. Since hey produce secondary metabolites under stress conditions such as pigments, carotenoids, hydrocarbons, vitamins, investigating the effects of factors on growth parameters biochemical composition microalgal biomass is needed ...

introduction: deficiency in mu opioid receptor signaling pathway is partially responsible for morphine tolerance. this deficiency may be due to uncoupling of opioid receptors and related g proteins, which in turn, it may be caused by their structural changes such as phosphorylation or by decreasing their abundance. in this study, we tried to investigate the effect of chronic administration of m...

BACKGROUND Serum retinol concentration determined by high-performance liquid chromatography (HPLC) is recommended by the World Health Organization to assess population vitamin A status. This assay is expensive, technically demanding and rarely available in developing countries. Our objective was a) to assess the diagnostic performance of proxy markers in detecting vitamin A deficiency and b) to...

cd8 deficiency is a rare primary immunodeficiency with low or absent peripheral cd8 cells which results from tap deficiency, zap 70 deficiency and cd8 α gene mutation. we report a 14 year old female who presented with a history of recurrent pneumonia, bronchiectasis, otitis, severe varicella, herpetic lesions of mouth, bilateral uveitis, and cataract formation since the age of 8 years. she had ...

Male Wistar rats were made potassium-deficient by feeding a diet low in potassium, while controls were pair-fed the same diet supplemented with potassium. Four weeks later 10 mg of T-1824 was injected into each rat. It was found that the characteristic granules which accumulate in the renal collecting tubule cells as a result of potassium deficiency were colored blue and that a diminished color...

Splenic infarction is most commonly caused by cardiovascular thromboembolism; however, splenic infarction can also occur in hematologic diseases, including sickle cell disease, hereditary spherocytosis, chronic myeloproliferative disease, leukemia, and lymphoma. Although 10% of splenic infarction is caused by hematologic diseases, it seldom accompanies autoimmune hemolytic anemia (AIHA). We rep...

Patients with coumarin induced skin necrosis presents with painful purpura and erythematous bluish swelling of the skin complicated by blister formation, hemorrhage and immanent gangrene. Coumarin induced hemorrhagic skin necrosis occurs within one week after initiation of coumarin treatment at time of prolonged INR caused by an imbalance within the vitamin K dependent anticoagulant and procoag...

A deficiency of free protein S, known to increase the risk of peripheral venous thrombosis, has not been well described in patients with cerebrovascular disease. In a pilot study of 35 patients with symptomatic cerebrovascular disease, using a qualitative crossed immunoelectrophoresis assay we found eight patients with a free protein S deficiency. A Laurell immunoelectrophoresis assay was used ...
