Despite extensive knowledge of the amino acid composition of beef-pork glucagon, and of the physiologic changes induced by its administration to animals and man, the role of glucagon in the homeostatic regulation of blood glucose level in normal and abnormal states remains to be defined. This fundamental gap in knowledge is the result of the lack of a method sufficiently specific and sensitive ...

Virtual learning environments (VLEs) may possess many advantages over traditional teaching methods in skills training that offer empowerment of constructing the skills by freely exploring a VLE. However, a conflict between the free exploration and ensuring the learning tasks tackled emerges in the learning process. A strategy to balance the conflict is to employ virtual tutoring agents to scaff...

Introduction: Leptin and Ghrelin are hormones that have been discovered in the last decade and were shown to be involved in appetite and metabolism regulation and body weight. Thyroid hormones are also    involved in general metabolism and changes in their circulating levels bring about changes in appetite and body weight. Results of animal and human studies regarding Leptinlevel and its re...

Bronchoalveolar lavage (BAL) was performed on 11 atopic patients with mild asymptomatic bronchial asthma and 11 healthy nonasthmatic volunteers. All asthmatic subjects had evidence of bronchial hyperresponsiveness to inhaled carbachol. The concentrations of leukotriene (LT) C4, LTD4, LTE4, LTB4, prostaglandin D2 (PGD2), platelet-activating factor (PAF) and histamine in BAL fluid measured. The l...

Background and Aims: Some nanoparticles can be used in immunoassays to increase sensitivity. This study aimed to evaluate a novel nano-immunoassay based on bovine serum albumin nanoparticles (BSA NPs). Materials and methods: At first, the nanostructure was synthesized, and then applied as a tag in the nano-immunoassay. Then the concentration of β-subunit of human chorionic gonadotropin ...

According to the regulations for international competitions all organizers of international championships and competitions are obliged to carry out doping control tests (blood tests, urine tests etc.) on athletes. The administration of hormones to athletes with the intention of improving performance has been a common practice for many years, and in the last ten years this practice has reached s...

Adverse reactions to ergotamine were noted in 16 out of 41 studies in which therapeutic doses of the drug were given to normal, healthy volunteers. In 17 of the studies 0.25 mg ergotamine was given by injection, 6 i.v. and 11 i.m., in 20 studies 2 mg ergotamine was given by mouth, and 4 subjects received 2 mg ergotamine by suppository. Plasma and urinary ergotamine was measured by radio-immunoa...

MATSUDA, S., SUKENO, N. and Ismnx, N . Different Types of Australia Antigen Detected by Radioimmunoassay and Immunoelectrosyneresis . Tohoku J. exp. Med., 1972, 108 (1), 95-96 A mixed human serum containing Australia (Au) antigen was fractionated by a discontinuous sucrose gradient centrifugation. When Au antigen in each fraction was assayed by radioimmunoassay (RIA) and immunoelectrosyneresis ...

Materials and Methods: Twenty menopausal women with intact uterus and ovaries (study group) and ten cases with total hysterectomy were selected through a random table among the referred menopause patients for hormone replacement therapy. Mean ages and menopause lengths of the study and control groups were similar. Ten cases and five controls had 15 days of transdermal 100 μm/d estradiol (TE) (g...
