Genetic and physiological influences on the rumen microbiome and metabolic status in Holstein cows.

Metabolic disorders in cows occur when physiological metabolic processes are disrupted, often due to nutritional imbalances. These disorders can significantly affect productivity, particularly in high-producing dairy breeds, such as Holsteins, especially during critical periods, including transition and early lactation. A key factor influencing nutritional efficiency is the rumen microbiome, which plays a vital role in fiber digestion, starch fermentation, and the production of VFA, as well as in microbial protein synthesis and vitamin synthesis.

Effect of store and forward teledermatology on quality of life: a randomized controlled trial.

Importance: Although research on quality of life and dermatologic conditions is well represented in the literature, information on teledermatology's effect on quality of life is virtually absent.

Objective: To determine the effect of store and forward teledermatology on quality of life.

Design: Two-site, parallel-group, superiority randomized controlled trial.

Growth enhancement of prolactin-sensitive mammary tumor by periaqueductal gray stimulation.

The weight of prolactin-insensitive and prolactin-sensitive tumors implanted in female rats was measured upon their sacrifice. The group that received periaqueductal gray (PAG) stimulation subsequent to prolactin-sensitive tumor implantation had statistically higher incidence of enhanced tumor growth than non-PAG stimulated control group (P less than .001).
