001). Using an ROC curve, a FAR angle cut off of 40° maximizes the ability to distinguish between CSP from normal pregnancies.

The FAR angle provides an easily obtainable and numerical measurement. CSP have larger FAR angle compared to normal controls with a distinguishing cut off of 40°. Larger studies are needed to determine if using the FAR angle can improve first trimester diagnosis for CSP.

Male Wistar rats were divided into four groups and provided drinking water containing 4% Taif RW, PbAc, 4% Taif RW followed by PbAc or normal water (controls). Serum for hormonal assays and testicular tissue for histopathological and immunohistochemical examinations and molecular study were obtained. Epididymal spermatozoa were collected for analysis. PbAc significantly reduced serum levels of follicle-stimulating hormone (FSH), luteinising hormone (LH) and testosterone, as well as sperm count and motility percentage. It also caused a significant reduction in SOD and catalase activities, testicular CYTP450SCC , CYP17α, StAR mRNA expressions and the percentage of Bcl-2 immunoreactivity. The percentage of caspase-3 and NF-ĸB immunoreactivities, as well as sperm abnormalities, was increased, as did the testicular degeneration associated with vacuolation and necrosis of spermatogenic cells. Pretreatment with Taif RW significantly reduced the negative effects of PbAc as shown by the increases in serum gonadotropins level, SOD and catalase activities, and percentage of Bcl-2 immunoreactivity, decreases in the percentage of caspase-3 and NF-ĸB immunoreactivities, and improved testicular histology and sperm parameters. These data provide evidence that Taif RW protects against testicular toxicity caused by PbAc.In females of haplodiploid animals, female production requires fertilization, whereas male production does not. Therefore, haplodiploid species can display extraordinary sex ratios. Constrained sex allocation occurs when a female cannot produce daughters. This can be due to virginity but may also occur after mating due to insemination failure, selfish genetic elements or physiological constraints. Here, we investigated the mechanism underlying constrained sex allocation in Pezothrips kellyanus. In this species some mated females produce highly female-biased broods, yet, for unknown reasons, others produce extremely male-biased broods. Using crossing experiments controlled for maternally inherited endosymbionts we confirmed that constrained females were successfully inseminated. Furthermore, male-biased offspring production was not paternally inherited, ruling out paternal sex ratio elements previously identified as sex ratio distorters in some parasitoid wasps. Next, we excluded mating time and paternal fitness effects (male size) on sex allocation. However, we found that constrained sex allocation only occurred in small females producing smaller eggs than large females producing larger eggs and female-biased broods. Consequently, the bimodal sex allocation pattern correlates with maternal condition, and may have arisen (adaptively or non-adaptively) in association with an egg size-mediated fertilization mechanism recently detected in some haplodiploids, with egg size positively affecting fertilization success.

Gastroesophageal reflux can occur during anaesthesia and may lead to esophagitis and occasionally oesophageal stricture formation. The aim of the study is to assess two omeprazole protocols on gastroesophageal reflux incidence and pH in anaesthetised dogs.

Fifty-five dogs undergoing elective ovariectomy were randomly assigned to omeprazole single dose 1mg/kg orally the evening before anaesthesia (20 dogs), omeprazole two doses 1mg/kg orally the evening and 3hours before anaesthesia (15 dogs), and control group that did not receive omeprazole (20 dogs). An oesophageal impedance/pH probe was used to measure gastroesophageal reflux incidence and pH during anaesthesia.

Gastroesophageal reflux was observed in 55% (11/20) of control dogs, 55% (11/20) of dogs receiving omeprazole once and 47% (7/15) of dogs receiving omeprazole twice. The incidence was not statistically significant different between groups. Gastroesophageal reflux pH (mean ± sd) was higher in dogs receiving omeprazole twice (6.3 ± 1.5), when compared to either control dogs (3.8 ± 1.1) or dogs receiving omeprazole once (4.1 ± 1.5). Strongly acidic reflux (pH< 4) was observed in 7% (1/15) of dogs receiving omeprazole twice versus 55% (11/20) and 35% (7/20) of control dogs and dogs receiving omeprazole once, respectively.

Omeprazole administered the evening and 3hours before anaesthesia increased gastroesophageal reflux pH and decreased the incidence of strongly acidic reflux in dogs. A single dose of omeprazole given the evening before anaesthesia had no effect on reflux pH.

To further evaluate the appearance of insulinoma in dogs on dual-phase CT angiography, given the disparity of findings in recent publications. NX-2127 To establish whether CT angiographic localisation of insulinoma correlates with surgical findings.

Single centre study of dogs with a final diagnosis of insulinoma which underwent abdominal CT angiography. Scans were retrospectively re-evaluated for specific features by two board-certified veterinary radiologists. These findings were also subsequently compared to surgical and histopathological reports to determine the accuracy of lesion localisation on CT.

Thirty-five cases were included in final analysis, with pancreatic nodules identified in 33. Twenty-one were confirmed as insulinoma with histopathology. Jack Russell Terriers were over-represented. Twenty of 21 cases with confirmed insulinoma and 27 of 33 overall showed hyperattenuation in the arterial phase. The mean size of pancreatic insulinoma on CT was 15.1 mm, and 18.2% were larger than 20 mm. Eighteen of 21 confirmed and eight of 12 suspected insulinomas caused a deformation of the pancreatic shape, with two only identified as a result of this feature as these lesions were isoattenuating throughout the study.
