In this task, you are given a abstract of article and corresponding title of an article. Your task is to generate label "yes" if title is right for article, otherwise generate "no".

Input: Consider Input: 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..

Input: Consider Input: Abstract: SPECIFIC AIMSOur previous studies implied the relation between lipid metabolism and amyloid beta protein (A) as 'a missing link in Alzheimer's puzzle' [FASEB J., vol. 12, p. 1097 (1998)]. In the present study, we evaluated the role of cholesterol in synaptic plasticity and neuronal degeneration by a combination of adult rat hippocampal slice technology, a well-established procedure for limited cholesterol efflux, lipid metabolic labeling, extracellular recording of CA1 field excitatory postsynaptic potentials (fEPSPs), and immunofluorescence. PRINCIPAL FINDINGS1. Increased cholesterol efflux impairs short- and long-term synaptic plasticitySynaptic plasticity is a fundamental feature of the central nervous system (CNS) that allows synapses to 'remember' previous activity and express plastic changes to fine-tune current synaptic action. In this study, we asked whether an increased cholesterol efflux induced ex vivo by normal human CSF-HDL3 and methyl--cyclodextrin (MCD) (a natural and model cholesterol ac....

Input: Consider Input: Abstract: The Caliciviridae family comprises positive-sense RNA viruses of medical and veterinary significance. In humans, caliciviruses are a major cause of acute gastroenteritis, while in animals respiratory illness, conjunctivitis, stomatitis, and hemorrhagic disease are documented. Investigation of virus-host interactions is limited by a lack of culture systems for many viruses in this family. Feline calicivirus (FCV), a member of the Vesivirus genus, provides a tractable model, since it may be propagated in cell culture. Feline junctional adhesion molecule 1 (fJAM-1) was recently identified as a functional receptor for FCV. We have analyzed the structure of this virus-receptor complex by cryo-electron microscopy and three-dimensional image reconstruction, combined with fitting of homology modeled high-resolution coordinates. We show that domain 1 of fJAM-1 binds to the outer face of the P2 domain of the FCV capsid protein VP1, inducing conformational changes in the viral capsid. This study provides the first structural view of a native calicivirus-protein receptor complex and insights into the mechanisms of virus attachment and uncoating..
