the aim of this study was measuring the amount of heavy metals (nickel, cobalt, cadmium, chromium and zinc) in different tissues of black fish (capoeta fusca). for this reason, in july 2010, 24 black fish was caught at the central part qanats of birjand. the results showed that between the whole length and the weight of fish and concentration of heavy metals in different observed tissues there ...

background: the phosphatidylinositol 3-kinase/akt signaling pathway is recognized as a key driver of cancer cell survival and proliferation, and is often contingent upon an impairment of expression/function of the pten tumor suppressor, a negative regulator of this pathway. in addition, the cytoskeletal signaling protein tensin 2 has also been implicated as a negative regulator of this pathway....

also serves to emphasize the areas of agreement and disagreement, so that the non-specialized reader can formulate an intelligent impression of the "firmness" of the various current concepts in the field. In addition to the discussions of the relation between lipids and arteriosclerosis, the Conference gave brief consideration to renal pressor substances and physical factors related to hyperten...

INTRODUCTIONCryosections are rapidly and relatively easily prepared prior to fixation, and they provide a good system for visualizing fine details of the cell. Although cryosections are physically less stable than paraffin- or resin-embedded sections, they are generally superior for the preservation of antigenicity and therefore the detection of antigens by microscopy. The preparation of cryose...

Concentrations of ampholytes in the nitrogen pool of ox ocular tissues and nervous tissues were analyzed systematically by an automatic amino acid analyzer with a special reference to their minor components. DCEC was found in lens and also in nervous tissues. Ophthalmic acid was found in lens (highest), in retina (moderate), and in vitreous humor and spinal cord (trace). Glutathione content was...

A B S T R A C T The specific activity of the branchedchain a-keto acid (BCKA) dehydrogenases was measured in normal tissues of the rat, monkey, and man, and in cirrhotic human liver. In the rat, specific activity of the dehydrogenases in liver, kidney, and muscle averaged 33, 26, and 0.4 U/g wet tissue, respectively; proportion of the body's content of the enzyme located in these three organs w...

normal healthy pulpal tissues were obtained from 19 impacted molars and symptomatic samples were obtained from 18 carious molars and premolars clinically diagnosed in all vital pulpal tissues. student's t-test revealed significant differences in il-2 concentrations, comparing symptomatic pulpal tissues with normal healthy samples (657, p

Introduction and Objective: liver is an important body organ without which life is impossible. Cyclophosphamide is an alkylating agent widely used as an anti-cancer (“antineoplastic” or “cytotoxic”) chemotherapy drug. The present study aimed to find a suitable antioxidant and examine the effect of vitamin E and selenium on reducing the side effects of cyclophosphamide on liver as a vit...

Subcutaneous emphysema is a relatively rare complication of dental treatment, although increasingly due to the use of high pressure air instruments. Many cases go unrecognized or are misdiagnosed. Majority of patients with this complication resolve spontaneously after 5 to 10 days, however some can advance to potentially life-threatening complications. A case of subcutaneous emphysema during re...
