The compensatory growth, proximate composition and amino acid contents changes of young yellow catfish (Pelteobagrus fulvidraco R.) (1.63-1.69 g) had been investigated using a 45-day cyclic feed deprivation and re-feeding experiment. The control group (S0) was fed daily with live tubificid worms (Limnodrilus hoffmeisteri), while the S1/4, S1/2, and S1/1 groups cyclically experienced one-day of ...

anti-müllerian hormone (amh) has been observed to decrease with the development of hemorrhagic anovulatory follicles (hafs) in mares. two studies were conducted to evaluate amh concentration in mares with hafs compared to seasonally anoestrous and cyclic mares, and to elucidate changes of amh with the development of luteinised unruptured follicles (lufs). in study 1, amh and progesterone were e...

Cyclic nucleotide-binding domains (CNBDs) that are present in various channel proteins play crucial roles in signal amplification cascades. Although atomic resolution structures of some of those CNBDs are available, the detailed mechanism by which they confer cyclic nucleotide-binding to the ion channel pore remains poorly understood. In this review, we describe structural insights about cyclic...

Animals with anterior or posterior neocortical lesions as well as intact control animals were evaluated for changes in a-adrenergic sensitivity at five postoperative times. Colonic temperature decreases were measured in response to clonidine at each of the postoperative periods. The result indicated that a heightened heat-loss response was induced by clonidine that lasted 21 or more days after ...

There has recently been a great deal of interest in cognitive interventions, particularly when applied in older adults with the goal of slowing or reversing age-related cognitive decline. Although seldom directly investigated, one of the fundamental questions concerning interventions is whether the intervention alters the rate of cognitive change, or affects the level of certain cognitive measu...

This study examines 5 types of personality continuity--structural, mean-level, individual-level, differential, and ipsative--in a representative population (N=498) and a twin and sibling sample (N=548) of children and adolescents. Parents described their children on 2 successive occasions with a 36-month interval using the Hierarchical Personality Inventory for Children (I. Mervielde & F. De Fr...

Personality-relationship transactions were investigated in a general population sample of young German adults with three assessments over 8 years. Four general findings were obtained. First, personality development was characterized by substantive individual differences in change. Second, bivariate latent growth models indicated that individual differences in personality change were substantial...

We have explored the possibilities that cell volume is regulated by the status of microtubule assembly and cyclic AMP metabolism and may be coordinated with shape change. Treatment of J774.2 mouse macrophages with colchicine caused rapid microtubule disassembly and was associated with a striking increase (from 15-20 to more than 90 percent) in the proportion of cells with a large protuberance a...

OBJECTIVES We investigated how fluctuations and linear changes in health and cognitive resources influence the motivation to engage in complex cognitive activity and the extent to which motivation mediated the relationship between changing resources and cognitively demanding activities. METHOD Longitudinal data from 332 adults aged 20-85 years were examined. Motivation was assessed using a co...

The purpose of this factorial study was to establish normative data for the Italian version of the Communication Attitude Test (CAT) in order to determine whether or not the speech-associated attitude reported by Italian children who stutter (CWS) differs significantly from that of their nonstuttering peers (CWNS). Toward this end, the Italian CAT was administered to 149 CWS and 148 CWNS betwee...
