[EX Q]: Abstract: Ractopamine hydrochloride (RAC) has consistently led to an advantage in carcass cutting yields of finishing pigs and remains a common feed additive in US finishing pig diets. Less is known about the effect of RAC on further processing characteristics. Some researchers have reported advantages in ultimate pH of the LM in pigs fed RAC. If a greater ultimate pH was also observed in hams, the increased pH could affect further processing characteristics and lead to better protein interaction and improved textural properties. The objective of this experiment was to determine if RAC-fed pigs yielded hams with a greater ultimate pH, and if so, whether or not that advantage improves textural properties and water retention of further processed hams. Two hundred hams from barrows and gilts fed RAC or control diets were selected based on HCW. Hams were fabricated into 5 separate pieces to determine cutting yields, and 6 muscles were evaluated for ultimate pH. Hams were processed to make cured and smoked hams. Ractopamine increased cutting yields of the whole ham (P < 0.0001), inside (P < 0.01), outside (P < 0.01), and knuckle (P < 0.01) when expressed as a percentage of chilled side weight. Ultimate pH of the rectus femoris, vastus lateralis, and semitendinosus were all 0.06 pH units greater (P < 0.05), the biceps femoris was 0.04 pH units greater (P = 0.02), and the semimembranosus and adductor muscles were 0.03 pH units greater in pigs fed 7.4 mg/kg of RAC when compared with control pigs. Cured hams from RAC-fed pigs were heavier at all stages of production. No differences were detected in binding strengths (P = 0.88) or protein fat-free values (P = 0.13) between RAC (9.06 kg and 20.37) and control hams (9.01 kg and 20.13). Ractopamine increased cutting yields, total weight of cured hams, and ultimate muscle pH. Ractopamine can be fed to pigs to achieve the desired growth characteristic advantages and cutting yields without affecting further processed ham characteristics..

[EX Q]: Abstract: Productive infection by human immunodeficiency virus type 1 (HIV-1) requires the activation of target cells. Infection of quiescent peripheral CD4 lymphocytes by HIV-1 results in incomplete, labile, reverse transcripts. We have previously identified G1b as the cell cycle stage required for the optimal completion of the reverse transcription process in T lymphocytes. However, the mechanism(s) involved in the blockage of reverse transcription remains undefined. In this study we investigated whether nucleotide levels influence viral reverse transcription in G0 cells. For this purpose the role of the enzyme ribonucleotide reductase was bypassed, by adding exogenous deoxyribonucleosides to highly purified T cells in the G0 or the G1a phase of the cell cycle. Our data showed a significant increase in the efficiency of the reverse transcription process following the addition of the deoxyribonucleosides. To define the stability and functionality of these full reverse transcripts, we used an HIV-1 reporter virus that expresses the murine heat-stable antigen on the surfaces of infected cells. Following activation of infected quiescent cells treated with exogenous nucleosides, no increased rescue of productive infection was seen. Thus, in addition to failure to complete reverse transcription, there was an additional nonreversible blockage of productive infection in quiescent T cells. These experiments have important relevance in the gene therapy arena, in terms of improving the ability of lentivirus vectors to enter metabolically inactive cells, such as hematopoietic stem cells..

[EX Q]: Abstract: G*Power (Erdfelder, Faul, & Buchner, 1996) was designed as a general stand-alone power analysis program for statistical tests commonly used in social and behavioral research. G*Power 3 is a major extension of, and improvement over, the previous versions. It runs on widely used computer platforms (i.e., Windows XP, Windows Vista, and Mac OS X 10.4) and covers many different statistical tests of the t, F, and chi2 test families. In addition, it includes power analyses for z tests and some exact tests. G*Power 3 provides improved effect size calculators and graphic options, supports both distribution-based and design-based input modes, and offers all types of power analyses in which users might be interested. Like its predecessors, G*Power 3 is free.. Title: siRNA specificity searching incorporating mismatch tolerance data.
