Abstract:
Abstract Background: A pilot study showing a decrease in androstenedione concentration in serum collected into gel-containing serum tubes (STs) triggered an investigation of the effect of serum collection tube on steroid hormone stability. Methods: In the main study, two tube types were examined: BD Vacutainer® SST™II Advance and BD Vacutainer® Serum Tube. Forty-seven serum samples from apparently healthy volunteers were collected and analysed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) for testosterone, androstenedione, 17-hydroxyprogesterone (17-OHP) (n=20); and oestradiol (

Abstract:
The methods for collecting and freezing deer semen have been, for the most part, limited to two species; red deer ( Cervus elaphus) and fallow deer ( Dama dama) (Asher et al., 2000 Anim. Reprod. Sci. 62, 195–211). The object of this study was to evaluate the progressive motility and effects of a thermal stress test on white-tailed deer (WTD) semen frozen in Biladyl extender (Mini Tube, Verona, WI, USA). Semen was collected by electroejaculation from WTD bucks (n=7, ages 1.5–2.5 years) during the breeding season. This trial was the second collection for one buck (#0025) and the third collection

Abstract:
The head represents the most dorsal and anterior extent of the body axis. InXenopus, the progressive determination of the head is an extremely complex process involving the activation and localized antagonism of a number of interdependent intracellular signaling pathways including the Wingless/Int-1 (Wnt), bone morphogenetic protein (BMP), and nodal-related pathways. The sequence of events that specify the head are: dorsal-ventral polarization and head organizer specification in the blastula; gastrulation; neural induction; and patterning of the anterior-posterior and dorsal-ventral neuraxes.

Abstract:
BackgroundAtaxia telangiectasia (A-T) is a rare multisystem disease with high early mortality from lung disease and cancer. Nutritional failure adversely impacts outcomes in many respiratory diseases. Several factors influence nutrition in children with A-T. We hypothesised that children with A-T have progressive growth failure and that early gastrostomy tube feeding (percutaneous endoscopic gastrostomy, PEG) is a favourable management option with good nutritional outcomes.MethodsData were collected prospectively on weight, height and body mass index (BMI) at the national paediatric A-T clinic

Abstract:
Frozen-thawed ram semen crosses the cervix poorly, necessitating laparoscopic insemination. Acceptable fertility can be achieved with frozen-thawed ram semen deposited at the external cervical opening if ram semen plasma (SP) is added (McPhie et al. 2000 14th ICAR 2, 78 abst). Homologous SP improves the fertility of frozen-thawed sperm of boars and dogs. Heterologous SP may have effects as well; the addition of bovine SP increased the ability of buffalo sperm (Syncerus caffer) to fertilize bovine oocytes in vitro (de Haas et al. 2003 Theriogenology 59, 392). The aim of the current study was to

Abstract:
Abstract Background Pneumopericardium is an uncommon clinical finding. It most commonly occurs after chest trauma but can also emerge as a complication following interventional or surgical procedures and can result in life-threatening complications. A high index of clinical suspicion should be present and once the condition is recognized, it should be managed promptly. Paucity of literature on pneumopericardium makes outlining any new case of paramount importance to emphasize the aspects of diagnosis and management of this rare condition.

Abstract:
It has been proposed that once good-quality sperm are collected, extended, and cryopreserved that the post-thaw quality will remain high regardless of the duration of storage. A previous study has suggested that there is no effect on post-thaw sperm motility of bovine semen stored in liquid nitrogen up to 13 years. However, no studies have reported the effect of extended storage of bovine semen in LN2. In this study, cryopreserved semen from Angus bulls (n = 25) was utilized. Time frames were assigned to each bull based on the year of collection and cryopreservation: time frame 1 (1960–1975),
