[Prospective methods of combat burn injury treatment].

The current article briefly reviews the projects of development of combat burn injury treatment as they have been presented in the US Armed Forces Institute of Regenerative Medicine 2013 annual report. Eleven projects have been reviewed, in particular: P12 polypeptide for limiting burn injury progression, gamma keratose gelfor enhancement skin cell survival, starch-polyurethane iodophor dressing effective against the most common burn infection, microorganisms, autologous stem and progenitor cells for single cell cytotransplantation by "skin gun" spray device or 3D skin bioprinting, a bioreactor for skin autotransplant expansion.

Effect of equine chorionic gonadotropin on weaning-to-first service interval and litter size of female swine.

We evaluated the effect of PMSG on the weaning-to-first service interval, total litter size and born alive litter size in swine. Four doses of PMSG (0, 500, 750 and 1,000 IU) were administered intramuscularly after weaning to sows at 3 different farms, grouped by parities (1, 2 and 3 or higher) and 2 distinct time periods. The associations among main effects and response variables were assessed by analysis of variance. Polynomial orthogonal terms were used to adjust the estimates of weaning-to-first service interval, total litter size and born alive litter size for the interaction effect of parity and PMSG treatment. The weaning-to-first service interval did not differ across periods and farms (P>0.05), although the interval was shorter (P<0.05) for Parity 3+ sows (4.97 d) than for Parity 1 sows (5.29 d), with no other differences in intervals observed across parities (P>0.05). Time period did not influence litter size (P>0.05), but there were differences in litter size across farms (P<0.05). Both litter size traits were lower for Parity 1 sows than for higher parity sows (P<0.05), but there were no differences in litter size between Parity 2 and 3+ sows (P>0.05). Litter size increased with PMSG dose in both Parities 1 and 2 (P<0.05), but not in Parity 3+ (P>0.05). A significant quadratic effect (P<0.05) of PMSG treatment in weaning-to-first service interval was observed for both Parity 1 and 2 sows, with the shortest intervals occurring with the 750 IU dose for Parity 1 sows. Administration of PMSG after weaning was associated with a shortened weaning-to-first service interval in Parity 1 sows and increased litter size in Parity 1 and 2 sows.
