The myofibril fragmentation index (MFI) is strongly associated with indices of meat tenderness, such as Warner-Bratzler shear force and sensory tenderness. The MFI is normally determined on fresh muscle. It is not known whether this index can be determined on frozen muscle. The objective of this experiment was, therefore, to determine whether there is a difference between MFI values of fresh an...

BACKGROUND Frozen- thawed embryo transfer is an essential part of ART treatment and outcomes of this procedure are associated with several clinical factors. Several studies have showed an increase level of IVF outcomes in women with sufficient vitamin D. OBJECTIVE whether treatment of vitamin D insufficiency can improve pregnancy rates in frozen-thawed embryo transfer cycles. MATERIALS AND ...

DRAGOEV, S. G., 2008. Inhibition of lipid peroxidation of frozen mackerel by pre-storage antioxidant superficial treatment. Bulg. J. Agric. Sci., 14: 283-289 With the help of TBARS the antioxidative effect of rosemary extract, rutin, quercetin, sodium erythrobate, BHT, α-tocopherol and a blend, containing rosemary extract, quercetin concentrate and sodium erythrobate on the lipid peroxidation o...

Ditylenchus dipsaci-infected and noninfected alfalfa plants in a naturally infested field were studied from July 1980 to September 1982. Forty-one percent of the plants died during the study. Ninety-seven percent of the plants that died were infected with D. dipsaci. Sixty-nine percent of the observed mortality occurred during winter. Forage yield of infected plants was significantly lower than...

BACKGROUND Little is known about the effect of transfusing fresh frozen plasma on the outcome after hepatectomy for hepatocellular carcinoma. PATIENTS AND METHODS Among 410 patients who underwent curative resection between 1992 and 2005, 180 patients had perioperative transfusion with whole blood or packed red blood cells and fresh frozen plasma (group A), while 46 patients were only transfus...

Survival, cryoprotection, and the time course for recovery of vital functions were studied in autumn-collected juvenile wood frogs (Rana sylvatica) following freezing at -1.5 degrees C for various periods. Frogs readily tolerated freezing for 3 or 9 d, but only 50% survived a 28-d freezing trial. Generally, the postfreeze return of vital functions (vascular circulation, pulmonary breathing, rig...

Our objective was to determine whether pregnancy rates in heat-stressed dairy cattle could be enhanced by timed embryo transfer of fresh (nonfrozen) or frozen-thawed in vitro-derived embryos compared to timed insemination. Ovulation in Holstein cows was synchronized by a GnRH injection followed 7 d later by PGF2 alpha and a second treatment with GnRH 48 h later. Control cows (n = 129) were inse...
