Evaluation of a long-acting recombinant bovine FSH for multiple ovulation and embryo transfer in dromedary camels.

The present study was conducted to test a new super-agonist recombinant bovine FSH (rbFSH) to induce superovulation (SOV) in dromedary camels. In experiment I, a single IM injection of 40, 60, 80, 100, or 120 µg rbFSH was administered (4 donors per group) to determine the effective dose resulting in acceptable multiple ovulation and embryo yield. Administration of 40 µg was ineffective, while 100 and 120 µg were associated with increased numbers of developed follicles, corpora lutea, and recovered embryos compared to administration of 60 and 80 µg.

Redefining physiological responses of moose (Alces alces) to warm environmental conditions.

We tested the concept that moose (Alces alces) begin to show signs of thermal stress at ambient air temperatures as low as 14 °C. We determined the response of Alaskan female moose to environmental conditions from May through September by measuring core body temperature, heart rate, respiration rate, rate of heat loss from exhaled air, skin temperature, and fecal and salivary glucocorticoids. Seasonal and daily patterns in moose body temperature did not passively follow the same patterns as environmental variables.

Glucose Metabolism as a Pre-clinical Biomarker for the Golden Retriever Model of Duchenne Muscular Dystrophy.

Purpose: Metabolic dysfunction in Duchenne muscular dystrophy (DMD) is characterized by reduced glycolytic and oxidative enzymes, decreased and abnormal mitochondria, decreased ATP, and increased oxidative stress. We analyzed glucose metabolism as a potential disease biomarker in the genetically homologous golden retriever muscular dystrophy (GRMD) dog with molecular, biochemical, and in vivo imaging.

Procedures: Pelvic limb skeletal muscle and left ventricle tissue from the heart were analyzed by mRNA profiling, qPCR, western blotting, and immunofluorescence microscopy for the primary glucose transporter (GLUT4).

The use of anti-Müllerian hormone as diagnostic for gonadectomy status in dogs.

In the veterinary practice, there is a need for a diagnostic tool to check the gonadal status in female dogs because it may be difficult to determine whether a female animal has been spayed or whether there are ovarian remnants. Although less prevalent, a similar situation pertains to male dogs. Anti-Müllerian hormone (AMH) is an important regulator of gonadal function and is a specific gonadal product that can be determined in circulation.
