BACKGROUND Strong oestrous symptoms in the mare can cause problems with racing, training and handling. Since long-acting progesterone treatment is not permitted in mares at competition (e.g. according to FEI rules), there is a need for methods to suppress unwanted cyclicity. Spontaneous dioestrous ovulations in the late luteal phase may cause a prolongation of the luteal phase in mares. METHO...

An analysis of 34 lunar lava flows and ponds in the eastern limb Smythii and Marginis basins was undertaken to examine and model the first stages of secondary crustal formation and assess processes involved in magma transport and eruption. In order to isolate the characteristics of single eruptive pisodes, we focused on discrete mare ponds adjacent to the major mafia. Mean values for areas and ...

Tung-Liang Lee, Shau-Ching Wen, Wei-Yuan Hsiao, Che-Kun James Shen, and Yu-Chiau Shyu (2009) Self-regulation of mouse p45/NF-E2 during murine erythroleukemia cell differentiation. Zoological Studies 48(3): 362-369. The complicated process of murine erythroleukemia (MEL) cell differentiation is precisely controlled by a group of transcription factors. One of those transcription factors, p45/NF-E...

A new abortigenic disease, now known as mare reproductive loss syndrome (MRLS), significantly affected the horse industry in the Ohio River Valley of the United States in late April and early May of 2001 and 2002. In 2001, approximately 25% of all pregnant mares aborted within several weeks (over 3,000 mares lost pregnancies), and abortion rates exceeded 60% on some farms. Mare reproductive los...

We report new high-precision laser fluorination three-isotope oxygen data for lunar materials. Terrestrial silicates with a range of δO values (−0.5 to 22.9‰) were analyzed to independently determine the slope of the terrestrial fractionation line (TFL; λ=0.5259±0.0008; 95% confidence level). This new TFL determination allows direct comparison of lunar oxygen isotope systematics with those of E...

BACKGROUND Sex steroid hormone receptors have been identified in the adrenal gland of rat, sheep and rhesus monkey, indicating a direct effect of sex steroids on adrenal gland function. METHODS In the present study, immunohistochemistry using two different mouse monoclonal antibodies was employed to determine the presence of oestrogen receptor alpha (ERalpha) and progesterone receptor (PR) in...

67 Evaluation of Premature Mammary CASE PRESENTATION A nine year-old Quarter Horse pregnant mare (277 days in gestation) was presented to Department of Large Animals, the Koret School of Veterinary Medicine, the Hebrew University of Jerusalem, for evaluation of premature udder development and vaginal discharge. According to the owner, the mare was used as a pleasure riding horse, and was genera...

The mare is seasonally polyestrus, having an anovulatory period during the short light days of late fall and early winter, and beginning to ovulate as the days become longer during the winter. The complete estrus cycle is typically about 3 weeks, with 5 to 7 days of estrus and approximately 2 weeks of diestrus. When a mare lives within the natural social structure of the horse, i.e. a family ba...

BACKGROUND Vitamin-D-binding protein (VDBP) is a low molecular weight protein that is filtered through the glomerulus as a 25-(OH) vitamin D 3/VDBP complex. In the normal kidney VDBP is reabsorbed and catabolized by proximal tubule epithelial cells reducing the urinary excretion to trace amounts. Acute tubular injury is expected to result in urinary VDBP loss. The purpose of our study was to ex...
