This study was done from September 2006 to May 2007. A total of 105 Menz breed sheep from Yemenze Gera Midir district in the Amhara National Regional State, Ethiopia. The spatial distribution of sheep keds (Melophagus ovinus) and chewing lice (Bovicola ovis) on Menz breed sheep were examined which were naturally infested. The densities if sheep keds and lice were determined through counting aft...

As shown in 15 male and 17 female developmentally-normal, 6-9 week (15-47 mm crown-rump length) embryos, intercorrelations (communalities) involving both mesial and distal deciduous teeth and proximal and distal segments of the developing hand were systematically higher in female embryos than in male embryos, without exception, a finding in surprising accordance with postnatal dimensional and t...

OBJECTIVES New early first-trimester diagnostic criteria for nonviable pregnancy recommended by the Society of Radiologists in Ultrasound via a multispecialty consensus panel extended the diagnostic size criteria of crown-rump length from 5 to 7 mm for embryos without a heartbeat and mean sac diameter from 16 to 25 mm for "empty" sacs. Our study assessed the potential impact of the new criteria...

Evidence for extra-hypothalamic expression of kisspeptinergic system is emerging. The present study documents the imuunolocalization kisspeptin and its receptor in placentome buffalo. Gravid uterus was collected from abattoir gestational age estimated by crown-rump length fetus. A section containing caruncle cotyledon used immunohistochemistry. Kp evident feto-maternal junctions with prominent ...

Methods A total of 1490 pregnant women were assessed for first trimester ultrasonography. They had routinely measured crown-rump length (CRL) and nuchal translucency (NT) for screening for Down syndrome between 11 and 14 weeks of gestation. Cases with a NT≥3 mm were counselled further regarding the risk of chromosomal abnormality and prenatal diagnosis by fetal karyotyping. A complete follow-up...

The standard deviations and the average body size of Hungarian Grey cattle examined by this method were found to be: height at withers 133,0 cm (sd:5,7); height of back 131,5 cm (sd:5,7); rump height 133,7 cm (sd:6,1) trunk length 157,6 cm (sd:9,7); chest depth 76,9 cm (sd:4,3); body length 152,6 cm (sd:10,6); width of chest 45,5 cm (sd:4,3). The discriminant function analysis of intra(Hungaria...

The known measurements for the determination of body proportions cannot be used practically in the neonate. The ratio of crown-rump distance to total length appears the most useful index for objective evaluation of disorders that influence body proportions in the neonate. Normal standards for this ratio in newborn infants from 27 to 41 weeks' gestation are presented in relation to gestational a...

The matching criteria were gestation (using an ultrasound crown–rump length or biparietal diameter measurement), duration of storage, and centre. Screening performance of the individual markers and combinations of markers together with maternal age was assessed using standard methods. In addition pairs of first and second trimester serum samples from 600 controls were tested to secure a larger ...

As shown in 138 embryos and fetuses in the 40-285 mm crown-rump length range, carpal and carpal-metacarpal "fusions" arise from incomplete separation of the cartilaginous precursors rather than from failure of initiation, thus accounting for the "fusions" seen in postnatal radiographs and the grooves that are evident enough in adult fusions. Radiographs selected from over 20,000 apparently norm...
