The endometrium acquires the ability to implant a hatched blastocyst only within a specific time termed the receptive phase. Ovarian steroid hormones are essential for structural and functional changes that prepare the endometrium to be receptive. Pinopodes have been suggested to be markers of uterine receptivity. The aim of this study was to compare the(More)
Differences in bone among racial/ethnic groups may be explained by differences in body size and shape. Previous studies have not completely explained differences among white, Asian, and Hispanic groups during growth. To determine racial/ethnic differences and predictors of bone mass in early pubertal girls, we measured bone mineral content (BMC) in white,(More)
Our study compares the bone mass of Hawaiian, Filipino, Japanese, and white women living in Oahu, Hawaii. Eligible women ranged in age from 25 to 34; all had bone mass measurements at the spine, calcaneus, and proximal and distal radius. Their average bone mineral density (BMD) remained stable with age at all four bone sites, indicating that the age range(More)
The aim of the study was to assess the efficacy of using a Gn-RH agonist implant (deslorelin, 4.7 mg, Suprelorin) to control sexual activity of male cats and reestablishment of sexual function after the implant removal 4 mo after placement. Using a control group (Group 1, n = 5), 22 domestic tomcats were given the implant subcutaneously in the region of the(More)
In spite of its incidence decreasing to 1% nowadays, prosthesis-related infection remains a research, diagnostic, therapeutic and cost-related problem. It can be defined as a presence of bacteria in the artificial joint space, which is significantly associated with evident laboratory and/or tissue markers, and clinical signs of running infection. We believe(More)
The ultrastructure of NCS was investigated in two groups of patients (15 in each) during the secretory phase of the normal menstrual cycle and after the hormonal stimulation performed in the IVF programme by GnRH-a, FSH and hCG. Three developmental stages of the NCS were classified. The most numerous were the NCS in the mature stage (type 2), less in the(More)
Ultrastructure of the superficial relief of the endometrial epithelium was investigated under the scanning (SEM) and transmission electron microscopes (TEM) in a group of patients after the hormonal stimulation, performed in the program of in vitro fertilization and embryotransfer. The results were compared with those obtained in a group of patients studied(More)
The article evaluates changes in the forest health status and nutrition, caused by the historical development of the air pollution load, in the Norway spruce (Picea abies L. Karst) stands in the Jizera Mts. The Jizera Mts. are located in northern Bohemia, on the border between the Czech Republic and Poland close to western Saxony (Zittau). The 19 research(More)
An unusual case of implant failure after revision total knee arthroplasty (TKA) is presented and the case report is completed with the results of an ensuing biomechanical study made to explain possible causes leading to a fracture of the tibial stem. For this we used electron microscopic and biomechanical analyses. There was no material defect found at the(More)
A four-year old, 26.5 kg, Boxer bitch was presented to the Department of Reproduction in the Clinic of Dogs and Cats with a six month history of vulvar swelling and vaginal discharge. General gynaecological examination showed an extremely swollen, oedematous and tough-elastic highly irritable vulva. A vaginal smear revealed the presence of superficial cells(More)
