Supplemental palmitic acid and chromium propionate impact production responses during the immediate postpartum in multiparous dairy cows.

Forty-eight multiparous Holstein cows were used in a randomized complete block design and assigned to one of 4 treatments in a 2x2 factorial arrangement of treatments to determine the effects of supplemental palmitic acid (C16:0) and chromium (Cr) on production responses of early-lactation cows. During the fresh period (FR; 1-24 d in milk), cows were fed one of 4 treatments: (1) a diet containing no supplemental C16:0 or Cr (CON); (2) diet supplemented with an 85% C16:0-enriched supplement (PA); (3) diet supplemented with Cr-propionate (CR); and (4) diet supplemented with a C16:0-enriched supplement and Cr-propionate (PACR). The C16:0-enriched supplement was added at 1.

Self-harm hospitalizations and neighbourhood level material and social deprivation in Canada: an ecological study.

Background: Socio-economic status is associated with self-harm at the individual and area level. In Canada, there is limited evidence on the relationship between area-level markers of socio-economic status and self-harm. The objective of this study was to assess the impact of small area-level material and social deprivation on rates of hospitalization due to self-harm.

The packaging signal of Xanthomonas integrative filamentous phages.

Unlike Ff, the packaging signal (PS) and the mechanism of integrative filamentous phage assembly remains largely unknown. Here we revived two Inoviridae prophage sequences, ϕLf2 and ϕLf-UK, as infectious virions that lysogenize black rot pathogen Xanthomonas campestris pv. campestris.
