Carbohydrate-containing structures in rat liver rough microsomes (RM) were localized and characterized using iodinated lectins of defined specificity. Binding of [125I]Con A increased six- to sevenfold in the presence of low DOC (0.04--0.05%) which opens the vesicles and allows the penetration of the lectins. On the other hand, binding of [125I]WGA and [125I]RCA increased only slightly when the...

Carbohydrate-containing structures in rat liver rough microsomes (RM) were localized and characterized using iodinated lectins of defined specificity. Binding of [l~sI]Con A increased sixto sevenfold in the presence of low DOC (0.040.05 %) which opens the vesicles and allows the penetration of the lectins. On the other hand, binding of [125I]WGA and [125I]RCA increased only slightly when the mi...

background ghrelin, a 28 amino acid peptide, is effective in control of appetite and body weight. acylated ghrelin peptide is the active form of this peptide which plays a major role in the body’s energy balance. objectives this study aimed to investigate the possible effect (s) of intensive resistance exercise on acylated ghrelin, growth hormone, glucose, insulin, and cortisol plasma levels. p...

there is growing evidence that lectin-carbohydrate interactions can mediate the infection of parasites to their insect vector. many insect species are host or vectors of protozoan or metazoan parasites that cause socially and economically important disease such as malaria and leishmaniasis. however, relatively little work has been undertaken concerning the interaction of insect immunity against...

We show that the yeast, Saccharomyces cerevisiae, contains two cAMP-binding proteins in addition to the well-characterized regulatory (R) subunit of cytoplasmic cAMP-dependent protein kinase (PKA). We provide evidence that they comprise a new type of cAMP receptor, membrane-anchored by covalently attached lipid structures. They are genetically not related to the cytoplasmic R subunit. The respe...

Heats of combustion and energy equivalents of cytoplasmic ATP have been estimated for glucose, 101 food proteins and 116 food fats based on amino acid and fatty acid composition data from food composition tables and the heats of combustion and energy equivalents of cytoplasmic ATP of each individual amino acid, fatty acid, glycerol and glucose. The isodynamic equivalents of carbohydrate, fat an...

background: inflammatory bowel disease unclassified (ibdu) is considered to be an aberrant immune response with loss of tolerance to many antigens. objective: this paper tries to address whether there is any value to test for auto-antibodies in such patients. methods: 60 patients with inflammatory bowel disease unclassified participated in the study. auto-antibodies to nuclear antigen, intestin...

Background Although ovarian tissue cryopreservation and transplantation is used for fertility preservation in patient undergoing cytotoxic treatments but obtaining good quality oocyte is still a debate. Xenotransplantation has been introduced as a reliable technique for better understanding of the transplantation conditions, but to achieve healthy embryos, the quality of obtained oocytes need t...

background: oral squamous cell carcinoma is the sixth most common malignancy in the world today.  ing1b/p33 is a newly-discovered tumor suppressor which enhances p53 activity. transfer of p33 protein from nucleus to cytoplasmic compartment has been previously reported in leukemias. the objective of this study was to determine the correlation between p33ing1b cytoplasmic transfer and lymph node ...
