An experiment has been performed to utilize the wasted and disposed fish from White Nile River after simple heat treatments (Sun drying, roasting, direct boiling and indirect boiling) in layers’ rations from 19 up to 40 weeks to replace the imported concentrate with the levels of 0, 1.5, 3.5 and 5% for all heat treatments. The crude protein of treated fish was 50.75, 52.50, 50.55 and 50.05% for...
An experiment was conducted to determine growth and carcass characteristics of male broilers subjected to early feed restriction. Restricted birds were fed equivalent to 1/5*BW0.67 Kcal/day/bird between days 7 and 14. On days 0 to 7 and 14 to 56, all chickens received feed ad-libitum. Diets of feed-restricted birds were supplemented with 15% higher methionin and cystine recommended by NRC (1994...
We previously reported the cloning and characterization of a novel nuclear hormone receptor transcriptional coactivator, which we refer to as NRC. NRC is a 2,063-amino-acid nuclear protein which contains a potent N-terminal activation domain and several C-terminal modules which interact with CBP and ligand-bound nuclear hormone receptors as well as c-Fos and c-Jun. In this study we sought to cl...
Introduction: The Martian north polar residual cap (NRC) lies on top of the north polar layered deposits (NPLD). The NRC is about 1m thick and composed primarily of large-grained, dust-poor water ice [1]. The mass balance of the polar cap is uncertain. Long-term monitoring reveals small reversible changes in its extent on an interannual basis [2]. Images with a pixel scale of up to 0.25 m/pixel...
Regulatory decisions should be made in the most expert and informed way since they are precipitated by real and perceived threats to human health, under the glare of public scrutiny. In 1994, the National Research Council (NRC) reported that the U.S. Environmental Protection Agency's (USEPA's) overall approach to assessing risks is fundamentally sound, but the Agency must more clearly establish...
علیرغم پیشرفتهای حاصله در صفات تولیدی طیور تجاری امروزی، بازنگری قابل توجهای در احتیاجات مواد معدنی کم نیاز آنها در سالهای اخیر صورت نگرفته است. یکی از مشکلات شایع در سیستمهای تولید جوجههای گوشتی امروزی که میتوان آنرا به کمبود عناصر کم نیاز مربوط دانست، مشکلات اسکلتی هستند. روی، عنصری ضروری است که به عنوان یک کوفاکتور در متالوآنزیمهای مختلفی عمل نموده و نقش مهمی در مسیرهای مختلف متابولیک...
the effect of3levels of methionine (nrc recommended, 5 percent more than nrc recommended and 10 percent more than nrc recommended) and 2 levels of fat (0 and 5 percent) on some economical traits (performance and carcass) of broilers using a 2x3 factorial experiment with completely randomized design based on two rearing stages, starter (0-3 wk) and grower (4-6 wk) was studied. anova of the effec...
Regression in melanoma is a frequent biological event of uncertain prognostic value as the lesion exhibits heterogeneous phenotypical features, both at the morphological and immunohistochemical level. In the present study, we examined the expression of tissue inhibitors of metalloproteinases (TIMP1, TIMP2 and TIMP3) in melanoma with regression. We specifically examined the expression levels of ...
Using an insertional mutagenesis approach, a series of Neurospora crassa mutants affected in the ability to control entry into the conidiation developmental program were isolated. One such mutant, GTH16-T4, was found to lack normal vegetative hyphae and to undergo constitutive conidiation. The affected gene has been named nrc-1, for nonrepressible conidiation gene #1. The nrc-1 gene was cloned ...
