Peroxisome proliferator-activated receptor delta-PPARδ agonist (L-165041) enhances bovine embryo survival and post vitrification viability.

The effect of L-165041 (PPARδ-agonist) on decreasing apoptosis and intracellular lipid content was assessed in fresh and vitrified-warmed in vitro -produced bovine embryos. It was hypothesised that the addition of L-165041 to the culture medium enhances development and cryopreservation. Oocytes were allocated to one of two treatments: control-standard culture medium, or L-165041 added to the medium on day1 with no media change.

Effects of vulvar width and antral follicle count on oocyte quality, in vitro embryo production and pregnancy rate in Bos taurus taurus and Bos taurus indicus cows.

It was hypothesized that Brahman cows have greater in vitro embryo production than Simmental cows, and that regardless of breed, antral follicle count (AFC) and vulvar width (VW) are positively associated with oocyte quality, embryo number and pregnancy rate. Brahman (Bos taurus indicus, n = 184) and Simmental (Bos taurus taurus, n = 99) cows were classified as having a large AFC (Brahman: ≥50, Simmental: ≥25); intermediate AFC (Brahman: >30 and ≤49; Simmental: >16 and <24) and small AFC (Brahman: <30, Simmental: ≤15). The VW was considered to be large (Brahman: >123 mm, Simmental: >80 mm); intermediate (Brahman: >102 mm and ≤123 mm; Simmental: >65 mm and ≤80 mm) and small (Brahman: ≤102 mm and Simmental: ≤65 mm).

n-3 Ingestion may modulate the severity of periodontal disease? Systematic review.

The aim of this study was to determine the effects of n-3 ingestion on periodontal disease. Besides, we also investigated the relationship between plasma concentrations of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and/or aracdonic acid (AA), and periodontal disease. An electronic search was performed in several databases with the following keywords: "n-3," DHA, EPA and polynsaturated fatty acids (PUFA) in combination with the term "periodontal disease" (PD).
