A multigeneration crossbred Meishan-White composite resource population was used to identify quantitative trait loci (QTL) for age at first estrus (AP) and the components of litter size: ovulation rate (OR; number of ova released in an estrous period) and uterine capacity (UC). The population was established by reciprocally mating Meishan (ME) and White(More)
The Chinese Meishan (ME) breed of pig is unique for many reproductive traits. Compared with Western breeds of swine, ME females reach puberty earlier, ovulate more ova per estrus, and have greater uterine capacity, while intact males (boars) have smaller testes and extremely elevated plasma levels of pituitary-derived glycoprotein hormones. In an effort to(More)
Catheters were placed into the vena cava of swine via the external jugular vein. The catheters were then passed subcutaneously through a cannula to the back and exteriorized. These catheters were impregnated with heparin and were functional for more than 46 days. Length of estrous cycle and hematology traits were not affected adversely by this technique.

We evaluated prospectively 100 patients, the largest reported series, with blepharospasm and orofacial-cervical dystonia, or Meige syndrome. The mean age at onset was 51.7 years, and 81% presented between the ages of 40 and 70. Women outnumbered men three to two. Blepharospasm was the initial symptom in 58 patients, but only 23 had involuntary movements(More)
A prospective clinical study was performed in 32 patients with multiple sclerosis (MS) to evaluate the sensitivity of lesion detection and accuracy of lesion localization by neurologic examination, delayed enhanced computed tomography (CT) with a double dose of contrast material, and proton magnetic resonance (MR) imaging. After neurologic examination(More)
The positive relationship between Sertoli cell number and testicular size emphasizes the importance of determining factors involved in the regulation of the Sertoli cell population. Based on data from other species and indirect evidence in the boar, it is generally accepted that porcine Sertoli cells proliferate rapidly throughout the early postnatal(More)
The field of genomics applies the dissection of genetic differences toward an understanding of the biology of complex traits. Quantitative trait loci (QTL) for testis size, plasma FSH in boars, and body composition (backfat) have been identified near the centromere on the X chromosome in a Meishan-White Composite resource population. Since thyroid function(More)
The zinc finger transcription factor Gata4, is associated with gonadal development in many species. The present study characterizes temporal and spatial localization of Gata4 throughout gonadogenesis in porcine embryos. Immunohistochemical studies illustrated that Gata4 protein is present in the coelomic epithelium prior to histological differentiation of(More)
