background polycystic ovarian syndrome (pcos) is the most common hormonal disorder in reproductive-age women. this syndrome is associated with many complications, so treatment of the disorder is usually warranted. objectives to evaluate the effects of a combined low-dose oral contraceptive (ld) and vitex agnus on the improvement of clinical and paraclinical parameters of pcos. methods this trip...

Mesenchymal stromal cells (MSCs) have the potential to treat various disease indications and are future of cell therapy-based regenerative medicine. Typically, MSCs cryopreserved in serum-containing freezing formulation supplied at clinical site, which necessities that this is removed before administration. This a cumbersome process, there an immediate need for identifying serum-free, xeno-free...

The propagation of neural precursors in culture is an essential tool for the study of the signaling matrix that regulates their proliferation, self-renewal, and generation of terminally differentiated progeny. Neural precursors can be expanded in vitro using both adherent and non-adherent culture protocols. The culture of fetal human neural precursors in the absence of serum as free-floating cl...

Although the normal thyroid gland secretes both levothyroxine (L-T4) and levotriiodothyronine (L-T3), normalization of serum TSH with L-T4-replacement therapy alone in hypothyroidism is generally believed to result in a normal serum L-T3 and to reflect a euthyroid state. However several recent studies suggest that this may not be the case. Accordingly, the relationship between serum free L-T4 a...

Blood was taken from women in each trimester of pregnancy at routine antenatal visits. Further samples were collected from an age matched control group of euthyroid women taking no medication. Free triiodothyronine and free thyroxine concentrations were measured by direct radioimmunoassay (Amerlex Kit methods, Amersham International, Amersham, Buckinghamshire).2 These free hormone assays use th...

Recently, it has been concluded that measurement of the serum free testosterone level is crucial for evaluating male gonadal function. However, the extent of the decline of serum free testosterone levels with aging and the actual levels in male infertility have not yet been clearly defined. In this study, the clinical significance of serum free testosterone levels was evaluated in a total of 24...

Serum concentration of FSH, LH, testosterone, prolactin,ACTH,cortisol, TSH, T ,T and resin Tuptake were measured in 146 men who were exposed to vesicants used by Iraqi regime, few days to 4 weeks prior to test'ing, Clinical and laboratory findings had confirmed that mustards had been used. Mean serum concentrations of FSH, LH, TSH and prolactin were not signi­ficantly different from normals.
