The use of appropriate method for genetic evaluation of dairy animals is an important aspect of dairy cattle production. Traditional 305-day lactation model does not account for the changes in environmental factors within 305-day lactation and may involve unjustified projection of incomplete lactations. The use of test-day model in the recent past has made it possible to economize the genetic e...

The colony-stimulating factors (CSFs) are cytokines involved in the production, differentiation, and activation of host phagocytes. During murine infection with Chlamydia trachomatis (MoPn), plasma CSF levels increased in euthymic (nu/+) and athymic (nu/nu) BALB/c mice. Levels declined later in infection, with the nu/+ mice resolving the infection but the nu/nu mice succumbing by day 16. Either...

The objective of this work was to study the role of free radicals in relation to ethylene production during ageing of cut carnation petals. Ethylene production by freshly cut flowers was negligible, but 8 d after cutting ethylene production began to increase and reached a peak by day 9, before beginning to decline again. The efflux of electrolytes (membrane damage index) increased 101% and 2 ,7...

Utilization of the three major corn reserve materials, starch, triglycerides (refined corn oil), and zein (storage protein), by Aspergillus flavus was monitored in vitro over a 7-day fermentation. Medium composition in which proportions of reserve materials initially approximated proportions in mature corn kernels changed little over the first 18 h. Subsequently, hydrolysis of both starch and t...

The wound healing process and production of tumour necrosis factor alpha (TNF-alpha) by peritoneal cells of 7-day and 14-day obstructive jaundice (OJ) and sham-operated rats were investigated. In the study the skin wound breaking strength was measured. In addition such histological and biochemical parameters as fibroblast and endothelial cell proliferation, inflammatory cell infiltration and hy...

Toxic shock syndrome-associated staphylococcal and streptococcal exotoxins were tested for an ability to induce the production of tumor necrosis factor (TNF). Staphylococcal enterotoxins B and C1, along with streptococcal pyrogenic exotoxin A, all induced TNF production in a dose-dependent manner, with production peaking on the average at 3 days but continuing over the 6 days tested. This time ...

Frozen-thawed spermatozoa collected from a beef bull (Japanese Black) were used for in vitro fertilization (IVF) of matured oocytes obtained from dairy (Holstein) and beef (Japanese Black) females. Embryos were examined for fertilization, cleavage rate, interval between insemination and blastocyst production (experiment I), total cell number per embryo and sex ratio during blastocyst formation ...

We clarified nitric oxide (NO) production in the rat uterus by electron paramagnetic resonance spectroscopy and with Fe-N-(dithiocarboxy) sarcosine complex (an NO-trapping reagent). We examined changes in NO production in the whole uterus, decidua, and myometrium (gestational days 13.5-21.5). The expression of nitric oxide synthase (NOS) isoforms was also examined by quantitative reverse transc...

Cell manufacturing is widely introduced to cope with the dynamically changing market demands. This study considers a scheduling method for a cell assembly system for the products that are characterized by the type and specification. A major set up is required at a cell for the change of types and a minor one for the change of specification within the same types. The scheduling will be made in t...
