We evaluated ovarian follicular dynamics in bonnet monkeys by employing trans-abdominal ultrasonography. Following the administration of human follicle stimulating hormone (hFSH) and/or human menopausal gonadotropin (hMG), multiple follicular development was assessed and their numbers, size and growth profiles were monitored. The ultrasonograms showed that the follicular antrum appeared distinctly anechoic with well-defined hyperechoic borders. Depending on the type, quantity (12.5-25 IU), and duration (6-9 days) of hormones administered, the number of developing follicles was 2-12 per ovary with their lowest diameter being 2 mm...

The olm (Proteus anguinus) is a troglomorphic, neotenous amphibian with extraordinary life expectancy and unique adaptations that deserve further investigation. A low reproductive rate and habitat decline render it threatened by extinction. Establishing captive populations for maintenance and artificial breeding may one day become crucial to the species. Longitudinal, in-vivo assessment of inner organs is invaluable to our understanding of reproductive physiology, health, and behavior. Using ultrasound, we measured heart rate and assessed health and reproductive status of 13 captive olms at Zagreb Zoo...

We report the first trimester three-dimensional ultrasonographic findings in a 13-week-old fetus with complex phenotype and a de novo 4.7 Mb multigene deletion encompassing chromosome region 20q13.13-q13.2 detected by chromosomal microarray. Fetal sonography detected radial-ray anomalies in the form of bilateral absence of thumbs and the left club hand deformity. The presence of single atrioventricular canal instead of the atrial septal defect typical for Holt-Oram syndrome pointed us to rather suspect the SALL4 related diseases...

Schwannomas are benign tumors derived from Schwann cells and their typical site of origin is the subcutaneous tissue of the extremities. Gastrointestinal localization of Schwannomas is extremely rare and the stomach is the prevalent site. Gastric schwannomas primarily occur in the gastric submucosa and are usually asymptomatic.We present a rare case of a solitary gastric schwannoma in a 51-year old male, which initially manifested with hematemesis by acute upper gastrointestinal (GI) bleeding. The upper GI-Endoscopy revealed a gastric submucosal tumor, 7 cm in size, located in the proximal corpus and fundus...
