Background and Aims: Although metal and metal oxide nanoparticles are used in different medical applications, they may have considerable toxicity on various cells, such as myocytes. Therefore, this study aimed to evaluate the toxicity of the naked and serum-treated silver nanoparticles (Ag NPs) and magnesium oxide nanoparticles (MgO NPs) on the cardiomyocytes. Materials and Methods: Cardiomy...

BACKGROUND When evaluating the toxicity of engineered nanomaterials (ENMS) it is important to use multiple bioassays based on different mechanisms of action. In this regard we evaluated the use of gene expression and common cytotoxicity measurements using as test materials, two selected nanoparticles with known differences in toxicity, 5 nm mercaptoundecanoic acid (MUA)-capped InP and CdSe quan...

Both assays are accepted reference methods for measurement of lactate dehydrogenase (LDH) activity (2-4). At pH 7.4, pyruvate -* lactate (P -* L) activity is about three times lactate -+ pyruvate (L P) activity, because equilibrium favors formation of lactate. Normal range for the P -* L assay is 130-265 spectrophotometric units at 25#{176} (3); normal range for the L P assay is 40-98 units at ...

background:envenomation by macrovipera lebetina (m. lebetina) is characterized by prominent local tissue damage, hemorrhage, abnormalities in the blood coagulation system, necrosis, and edema. however, the main cause of death after a bite by m. lebetina has been attributed to acute renal failure (arf). it is unclear whether the venom components have a direct or indirect action in causing arf. t...

The work of Ropes and Bauer (1953) has focused attention on the analysis of synovial fluid in the differential diagnosis of joint effusion. White blood cell total and differential counts, glucose assay, and mucin precipitation tests have thus all been applied to the distinction of non-inflammatory, mild inflammatory, severe inflammatory, and infectious effusions. These analyses do not, however,...

Background: Platelets rapidly lose their qualities usually after 5 day of storage. Different standard methods have been recommended to check the quality of platelets during storage which some of them show better correlation with other quality markers during storage. The purpose of this study was to demonstrate if platelet factor 3 (PF3) assay could be an indicator of storage lesion and provide ...

BACKGROUND Cancer is one of the leading cause of mortality. Even though efficient drugs are being produced to treat cancer, conventional medicines are costly and have adverse effects. As a result, alternative treatments are being tried due to their low cost and little or no adverse effects. Our previous study identified one such alternative in rice callus suspension culture (RCSC) which was mor...

Purpose: Ischemia-reperfusion (I/R) injury exacerbates myocardial cell death (including apoptosis and necrosis), leading to complications such as arrhythmias, stenosis, microvascular obstruction heart failure, it is particularly important seek new strategies mitigate reperfusion injury. In this paper, we will investigate whether atorvastatin can alleviate ischemia-reperfusion verify its molecul...
