Cytoplasmic microtubules appear to play a role in the secretion of a variety of protein and protein hormones. Involvement of microtubules in renin secretion has been hypothesized but not established. The present studies were designed to determine: 1) if the antimicrotubule drug, colchicine, would alter plasma renin concentration (PRC); and 2) if changes in PRC could be related to an effect on c...

Humans and animals control their walking rhythms to maintain motion in a variable environment. The neural mechanism for controlling rhythm has been investigated in many studies using mechanical and electrical stimulation. However, quantitative evaluation of rhythm variation in response to perturbation at various timings has rarely been investigated. Such a characteristic of rhythm is described ...

Life experiences for corresponding age cohorts in the United States (US) and the People's Republic of China (PRC) have been dramatically different. If cohort effects account for cross-sectional age differences in mean levels of personality traits, different patterns of age differences should be seen in samples from the US and the PRC. The present study examined scores on scales from the Califor...

BACKGROUND Replication capacity (RC) of specific HIV isolates is occasionally blamed for unexpected treatment responses. However, the role of viral RC in response to antiretroviral therapy is not yet fully understood. MATERIALS AND METHODS We developed a method for predicting RC from genotype using support vector machines (SVMs) trained on about 300 genotype-RC pairs. Next, we studied the imp...

Bacterial strains and growth conditions. Fast-growing soybean Rhizobium strains USDA 191, USDA 192, USDA 193, USDA 194, USDA 201, USDA 205, USDA 206, USDA 208, USDA 214, USDA 217, and USDA 257 were isolated from soil or nodules collected in the PRC (20). Slow-growing soybean rhizobium strains PRC 005, PRC 74, PRC 113-2, PRC121-6, PRC 2031, and PRC B15, were oHtained from T. S. Hu, Institute of ...

Results from imaging and lesion studies of item recognition memory have suggested that the hippocampus supports memory for the arbitrary associations that form the basis of episodic recollection, whereas the perirhinal cortex (PRc) supports familiarity for individual items. This view has been challenged, however, by findings showing that PRc may contribute to associative recognition, a task tho...

UNLABELLED Objective. Peritoneal protein clearance (PrC) is recognized as a new marker of systemic endothelial dysfunction and predictor of mortality in patients on peritoneal dialysis (PD). Given that angiotensin-converting enzyme inhibitors (ACEI)/angiotensin II receptor blockers (ARBs) could improve endothelial dysfunction in the general population, we aim to explore whether this benefit is ...

Foram entrevistados 104 e 105 consumidores nas feiras-livres de Penedo (PEN) Porto Real do Colégio (PRC) – Alagoas, Brasil. Ao citarem tilápia como espécie preferida para consumo (26 22 consumidores), foram caracterização socioeconômica das preferências aquisição peixes. Houve maioria homens em PEN mulheres PRC, sendo as idades médias 41,77 44,62 anos. Baixas escolaridade renda familiar são car...

Regular firing neurons can be seen as oscillators. The phase-response curve (PRC) describes how such neurons will respond to small excitatory perturbations. Knowledge of the PRC is important as it is associated to the excitability type of neurons and their capability to synchronize in networks. In this work we present a novel method to estimate the PRC from experimental data. We assume that con...

In this paper we investigate the Presentational Relative Clause (PRC) construction. In both the linguistic and NLP literature, relative clauses have been considered to contain background information that is not directly relevant or highly useful in semantic analysis. In text summarization in particular, the information contained in the relative clauses is often removed, being viewed as non-cent...
