Serum oxytocin levels in patients with depression and the effects of gender and antidepressant treatment.

Sep 2009 Abnormalities in the neurohypophyseal system have been reported in depression. This study aimed to investigate serum oxytocin levels in patients with depression and the effects of gender and antidepressant treatment on these levels. Serum oxytocin ... Read more...

Vitamin D metabolites as clinical markers in autoimmune and chronic disease.

30 Aug 2009 Recent research has implicated vitamin D deficiency (serum levels of 25-hydroxyvitamin D <50 nmol/L) with a number of chronic conditions, including autoimmune conditions such as multiple sclerosis, lupus, and psoriasis, and chronic conditions such ... Read more...

Underlying mechanism of penehyclidine hydrochloride on isolated rat uterus.

30 Jul 2009 We investigated the underlying mechanisms of penehyclidine hydrochloride (PHC), a novel selective anticholinergic drug on isolated rat uterus. The method of radio-immunity assay was further employed to determine cyclic adenosine mono phosphate ... Read more...

Technical information about 'Radioimmunoassay'

Definition: Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.
