It happens rarely, but it is possible for a pancreatitis attack to activate the endocrine portion of the organ back into being capable of producing insulin once again in dogs. [citation needed] It is possible for acute pancreatitis to cause a temporary, or transient diabetes, most likely due to damage to the endocrine portion's beta cells. [23]
Female dogs bleed during estrus, which usually lasts from 7–13 days, depending on the size and maturity of the dog. Ovulation occurs 24–48 hours after the luteinizing hormone peak, which occurs around the fourth day of estrus; therefore, this is the best time to begin breeding.
Fertilization is the fusion of gametes to produce a new organism. In animals, the process involves a sperm fusing with an ovum, which eventually leads to the development of an embryo. Depending on the animal species, the process can occur within the body of the female in internal fertilization, or outside in the case of external fertilization.
In genetics, a maternal effect occurs when the phenotype of an organism is determined by the genotype of its mother. [1] For example, if a mutation is maternal effect recessive, then a female homozygous for the mutation may appear phenotypically normal, however her offspring will show the mutant phenotype, even if they are heterozygous for the mutation.
If the blood glucose level falls to dangerously low levels (as during very heavy exercise or lack of food for extended periods), the alpha cells of the pancreas release glucagon, a peptide hormone which travels through the blood to the liver, where it binds to glucagon receptors on the surface of liver cells and stimulates them to break down glycogen stored inside the cells into glucose (this ...
Approximately 38.4 million Americans had been diagnosed with diabetes as of 2021 — but about three times that many are in danger of developing the disease, even if they don’t know it. Nearly ...
Dogs who still produce lactase enzymes can still have digestive problems related to dairy, though they're bound to be a lot less severe. Without the enzymes (or with just a small amount), the ...
During this process, the presence of pyknotic nuclei in the antral layers of the membrane can be observed. [23] Apoptosis ensures that the follicle gets eliminated without triggering an inflammatory response. [24] Antral follicular atresia causes no damage to basal granulosa cells.
