Among invertebrates, specific pheromones elicit inherent (fixed) behavioural responses to coordinate social behaviours such as sexual recognition and attraction. By contrast, the much more complex social odours of mammals provide a broad range of information about the individual owner and stimulate individual-specific responses that are modulated by(More)
The whole animal, and the pectoralis muscle in particular, grows at a greatly enhanced rate in chickens selected for meat production (broilers) when compared to those selected for egg production (layers). As part of an ongoing study to analyse muscle protein dynamics under conditions of rapid growth, we have embarked upon a preliminary characterisation of(More)
Many mammals use scent marking for sexual and competitive advertisement, but little is known about the mechanism by which scents are used to locate mates and competitors. We show that darcin, an involatile protein sex pheromone in male mouse urine, can rapidly condition preference for its remembered location among females and competitor males so that(More)
Previous investigations of the effects of clenbuterol have used suprapharmacological doses that induce myocyte death, alter muscle phenotype, and do not approximate the proposed therapeutic dose for humans. Recently, we reported that smaller doses of clenbuterol induce muscle growth without causing myocyte death. In the present study we used histochemical(More)
BACKGROUND Knowledge of breed associations is valuable to clinicians and researchers investigating diseases with a genetic basis. HYPOTHESIS Among symptomatic dogs tested for exocrine pancreatic insufficiency (EPI) by canine trypsin-like immunoreactivity (cTLI) assay, EPI is common in certain breeds and rare in others. Some breeds may be overrepresented(More)
Cauxin is an abundant protein in feline urine. We have used proteomics strategies to characterize cauxin from the urine of domestic cats and a number of big cat species. Proteins were resolved by gel-based electrophoretic purification and subjected to in-gel digestion with trypsin. The resultant tryptic peptides were mass-measured by matrix-assisted laser(More)
OBJECTIVE The objective of the study was to determine the value of serial ultrasonographic cervical length (CL) measurements after cerclage to predict preterm delivery. STUDY DESIGN Retrospective ultrasonographic and outcome data from singleton pregnancies with cerclage were reviewed. Using transvaginal ultrasound (TVS), overall CL obtained before(More)
We studied the efficacy of in utero hematopoietic stem cell transplantation and the ability of such transplantation to induce tolerance in a fetal normal mouse allogeneic model. In 9 of the 162 surviving recipients (5.6%), cells of donor origin were detected after birth. The highest engraftment rate was achieved by transplanting fetal liver cells in a(More)
The common carp (Cyprinus carpio) has a well-developed capacity to modify muscle properties in response to changes in temperature. Understanding the mechanisms underpinning this phenotypic response at the protein level may provide fundamental insights into the molecular basis of adaptive processes in skeletal muscle. In this study, common carp were(More)
A collaborative, retrospective study of patients who had undergone multifetal pregnancy reduction (MFPR) to twins and subsequent genetic amniocentesis was performed to determine if amniocentesis increased the risk of pregnancy loss. Seventy-nine patients from three centres underwent MFPR and subsequent amniocentesis. The pregnancy loss rate was 5.06 per(More)
