1.1 Regulation of female reproductive system Regulation of female reproductive system consists of very complex interactions between the hypothalamus, neurohypophysis and ovaries. Beginning from the embryologic stage, female reproductive system is regulated by the brain. Ovarian hormone production is supressed by the hypothalamo-hypophyseal control mechanism till the end of the childhood period ...

BACKGROUND Egg laying in Magang geese is characterized by extended interruption between clutches and lowing laying rate. Both the ovarian follicular development and ovulation characteristics, and the associated endocrine and molecular regulatory mechanisms involved are poorly understood, but could be important for guiding development of molecule aided selection of egg laying performances in gee...

To examine the detailed composition of glycosaminoglycans during bovine ovarian follicular development and atresia, the specialized stromal theca layers were separated from the stratified epithelial granulosa cells of healthy (n=6) and atretic (n=6) follicles in each of three size ranges: small (3-5mm), medium (6-9mm) and large (10mm or more) (n=29 animals). Fluorophore-assisted carbohydrate el...

OBJECT To identify pre-operative prognostic parameters for survival in patients with spinal epidural neoplastic metastasis when the primary tumour is unknown. METHODS This study was a retrospective chart review of patients who underwent surgery for spinal epidural neoplastic metastases between February 1997 and January 2011. The inclusion criteria were as follows: known post-operative surviva...

The present studies were undertaken to examine the expression of the high density lipoprotein (HDL) receptor, SR-B1 messenger RNA (mRNA) in ovarian cell types during folliculogenesis and luteinization using in situ hybridization histochemistry and to examine its hormonal regulation using Northern blots. For the in situ study for HDL receptor mRNA localization, 21-day-old rats were treated with ...

Normal saline or air is used to identify loss of resistance during identification of the epidural space for combined spinal-epidural analgesia. Following epidural needle placement using air for loss of resistance, up to 80% of parturients move, grimace, vocalise or experience paraesthesia or dysaesthesia during subsequent dural puncture by a spinal needle. We compared the effects of saline vers...

Through the past decades, many attempts have been made to standardize lumbar disk herniation–related terminology (1, 2). Two different, and not necessarily parallel, sets of characteristics of a herniated disk (HD) are taken into account in the reporting of cross-sectional images of the lumbar spine. First, is the absolute attributes of the HD (ie, morphology, location, volume, etc), and second...
