Omega-3 Fatty Acid and Vitamin D Supplementations Partially Reversed Metabolic Disorders and Restored Gut Microbiota in Obese Wistar Rats.

Obesity is a global public health issue linked to various comorbidities in both humans and animals. This study investigated the effects of vitamin D (VD) and omega-3 fatty acids (ω3FA) on obesity, gut dysbiosis, and metabolic alterations in Wistar rats. After 13 weeks on a standard (S) or High-Fat, High-Sugar (HFHS) diet, the rats received VD, ω3FA, a combination (VD/ω3), or a control (C) for another 13 weeks.

Preventive effects of a nutraceutical mixture of berberine, citrus and apple extracts on metabolic disturbances in Zucker fatty rats.

Background: The prevention of obesity represents a major health and socio-economic challenge. Nutraceuticals are regularly highlighted for their beneficial effects in preventing the metabolic disturbances associated with obesity. However, few studies have described the combined action of nutraceutical mixtures combining polyphenols with alkaloids.

The advantages of using a combination of LDL and glutamine in comparison with TRIS egg yolk and Equex® STAMP extenders in the cryopreservation of canine semen.

Twenty semen samples taken from 5 dogs were frozen in liquid nitrogen at -196 °C in four different extenders: one control extender based on 20% egg yolk, 6% LDL alone (low density lipoproteins: the active cryoprotective principle in chicken egg yolk), 6% LDL combined with 20 mmol glutamine, and Equex® (a reference extender that we wish to compare with the LDL-glutamine combination). After thawing, spermatozoal motility was evaluated using a HAMILTON THORNE CERROS 12 image analyzer; the percentage of motile spermatozoa was 27.7% in the egg yolk extender (p<0.

Freezing canine sperm: comparison of semen extenders containing Equex and LDL (Low Density Lipoproteins).

Chicken egg yolk is held as an excellent cryoprotective agent for freezing canine semen. Recent advances have enabled the extraction of low density lipoproteins from egg yolk, which are responsible for the cryoprotective abilities of the latter. The objective of this article was to compare 3 semen extenders for freezing canine semen: 2 containing egg yolk (Tris egg yolk and Equex STAMP) and one containing 6% LDL.
