nonsignificant differences between cutoffs for serum and plasma and between assays are encouraging regarding the ease of interpretation by clinicians and laboratories. Also encouraging were improvements in the analytical sensitivity of these newergeneration assays. Interestingly, only 3 samples were identified as above the 99th percentile by all 3 assays. The mechanisms responsible for this lac...

A study was conducted to determine whether treatment with deslorelin, a gonadotropin-releasing hormone (GnRH) analog, produced anestrus in gilts and to test the ability of exogenous gonadotropin treatment with a combination of 400 IU equine chorionic gonadotropin and 200 IU human chorionic gonadotropin to induce estrus in GnRH analog-treated gilts. Twelve days after the third estrus, 11 gilts e...

BACKGROUND Solitary fibrous tumors are rare tumors of mesenchymal origins, most commonly seen arising from the pleural lining of the lungs. These are generally benign tumors, which in rare cases have been identified to be associated with multiple para-neoplastic syndromes. CASE REPORT This is a case of a solitary fibrous tumor of the pleura in a 49 year old female which was found to be associ...

OBJECTIVE We report an unusual case of recurrent ectopic pregnancy in the distal remnant after partial salpingectomy. CASE REPORT A 23-year-old woman underwent laparoscopic right partial salpingectomy because of right tubal pregnancy. She returned to our hospital 2 years later with a positive pregnancy test and lower abdominal pain. Transvaginal ultrasonography revealed no intrauterine gestat...

The glycoprotein hormones lutropin (LH) and chorionic gonadotropin (CG) share a common structure consisting of an identical alpha subunit noncovalently linked to a hormone-specific beta subunit. While LH is produced in the anterior pituitary, CG is synthesized in placenta. To compare the assembly, processing, and secretion of human LH and CG in the same cell type, we have expressed their subuni...

Stability of free beta-human chorionic gonadotropin in maternal blood upon storage at ambient and refrigerator temperatures as well as stability under conditions simulating postal transport were studied. A group of 26 women in the first trimester of pregnancy were included in the study, blood samples were taken during the routine check-up. Blood samples were aliquoted stored in different condit...
