Background: Previous studies have shown that progesterone increases the ventilatory performance in healthy individuals and in patients with chronic obstructive pulmonary disorders. The study was designed to investigate the effect of a single intramuscular administration of progesterone on ventilatory performance in adult trauma patients during partial support mechanical ventilation. Methods: Fo...
Spontaneously occurring spike-wave discharges (SWDs) and serum concentrations of ovarian steroid hormones were investigated before, during and after pregnancy in WAG/Rij rats, a rat strain with genetically determined absence seizures. Eight groups of rats were included in the assays of progesterone and estradiol: rats at diestrus, at various days of pregnancy and at lactating days. The number o...
Primiparous cows with low body condition at calving have an extended anovulatory period. Induction of ovulation and oestrus is possible with progesterone treatment but the response to this treatment differs between Friesian and Jersey breeds. The objective of this study was to describe changes in pulsatile LH secretion and the synchrony of developing ovarian follicles that occur during a proges...
Background & Aims: Breast cancer is the most common cancer in women. Nearly 50% of breast cancers are dependent to sex hormones, and the effects of these hormones are mediated by their binding to specific receptors. Also p53 protein is mutated in about half of cancers including breast cancer and high level of p53 protein is a common feature of many human malignant cancers. Given that T47D cell...
Follicle deviation is characterized by continued growth of the largest (developing dominant) follicle and reduced growth of the smaller (subordinate) follicles. The aim of the present study was to test the following hypotheses: (1). oestradiol contributes to the depression of circulating FSH encompassing follicle deviation and (2). oestradiol plays a role in the initiation of deviation. Heifers...

The purpose of the present study was to investigate whether the electrical resistance values of the cervical mucus and/or blood οestradiol-17β and progesterone concentrations at mating, after oestrous synchronisation during the anoestrous or oestrous period in ewes, are related to fertility. Oestrus was induced by medroxyprogesterone acetate-impregnated intravaginal sponges (Veramix, Upjohn, US...
in this study, the relationship between teachers’ creative and critical thinking skills and their reflectivity in teaching was investigated. to this end, three questions were raised. these questions were intended to determine whether there was a significant relationship between teachers’ creative thinking skills and their reflectivity in teaching; whether there was a significant relationship be...
Peripheral serum progesterone concentrations were evaluated in beef heifers following breeding collected on d 6 +/- 1, 9 +/- 1 collected on d 6 +/- 1, 9 +/- 1 and 12 +/- 1 (estrus = d 0) after the puberal estrus of all heifers and after the third estrus of E3 heifers. Progesterone concentrations were higher (P less than .05) for heifers in E1 compared with heifers in E3 on d 6, 9 and 12 after b...
