We establish that the elliptic equation ∆u + f(x, u) + g(|x|)x · ∇u = 0, where x ∈ R, n ≥ 3, and |x| > R > 0, has a positive solution which decays to 0 as |x| → +∞ under mild restrictions on the functions f, g. The main theorem extends and complements the conclusions of the recent paper [M. Ehrnström, O.G. Mustafa, On positive solutions of a class of nonlinear elliptic equations, Nonlinear Anal...

Four hundred and fifty 1-d-old male Lingnan Yellow broiler chickens were used to investigate the effects of Clostridium butyricum on growth performance, immune function, and cecal microflora. The birds were randomly assigned to 5 treatments and offered the same antibiotic-free basal diets for 42 d. The treatments were as follows: no addition (control), 1 × 10(7) cfu C. butyricum/kg of diet (CB1...

Rates of conversion of alpha-linolenic acid (alpha-LNA, 18:3n-3) to docosahexaenoic acid (DHA, 22:6n-3) by the mammalian brain and the brain's ability to upregulate these rates during dietary deprivation of n-3 polyunsaturated fatty acids (PUFAs) are unknown. To answer these questions, we measured conversion coefficients and rates in post-weaning rats fed an n-3 PUFA deficient (0.2% alpha-LNA o...

The effects of goitrogens on the thyroid gland have been much studied and calcium is considered as a goitrogen in some cases. Since the level of calcium is high in drinking water of some cities of Khozestan province, the effects of high calcium intake on the function of thyroid gland is investigated in this study. For this purpose the concentration of thyroid hormones is measured in rats. The s...

Ameliorative potential of antioxidants –vitamins C and E on blood profile of Clarias gariepinus fed diets contaminated with varied levels of fumonisin B1 (FB1) was evaluated. Fusarium cultured maize containing FB1 were used to formulate diets containing approximately 2.5, 5.0, and 7.5 mg FB1/kg constituting diets 2, 3, and 4, respectively and other nine diets constituting Diets 5 - 13 with the ...

The present study was carried out to investigate the effects of dietary antioxidants on pro-inflammatory cytokines, heat shock protein (HSP) and antioxidant status in broiler chicks under summer conditions. A total of 162, 3-d-old broiler chicks were randomly assigned to a basal diet (CON) and the basal diet supplemented with vitamin C (200 mg/kg diet, VCD) or vitamin E (100 mg/kg, VED) until 3...

The CCAAT/enhancer-binding protein beta (C/EBPbeta) is required for adipocyte differentiation and maturation. We have studied the role of the transcription factor, C/EBPbeta, in the development of diet-induced obesity. Mice with a deletion in the gene for C/EBPbeta (C/EBPbeta(-/-)) and wild-type mice were fed a high-fat diet (60% fat) for 12 weeks. The C/EBPbeta(-/-) mice lost body fat, whereas...

The time of onset of chest pain was studied prospectively in 1154 consecutive patients admitted to a coronary care unit with myocardial infarction during a five year period. Statistical analysis confirmed a previous finding in a retrospective study of a bimodal frequency distribution with peaks in the time of onset of chest pain between 2330 and 0030 hours and between 0630 and 0830 hours. Many ...

Two hundred sixteen previously molted Dekalb Delta Leghorn laying hens (78 wk of age) were utilized to determine the effect of phytase on the ileal digestibility of amino acids. The hens were randomly arranged in a 3 x 2 factorial to evaluate three diet types that were corn-soybean meal (C-SBM), C-SBM-meat and bone meal (C-SBM-MBM), and C-SBM-wheat middlings (C-SBM-WM) and two levels of phytase...
