The aim of the present study was to determine the extent to which aesthetic preference, previously attributed to cerebral dominance, may be determined by reading habits. One hundred and sixty two normal subjects were presented pairs of images, one being the mirror-image of the other, and were asked for their aesthetic preference. Half of the subjects were left-to-right readers (French subjects)...

the present study reports the changes in the phytoplankton community structure in taklong island national marine reserve (tinmar), guimaras island, philippines. quantification of pah yielded undetectable results, whereas, primary productivity, phytoplankton density, and diversity values were higher as compared to samples before the oil spill and samples from the reference site. sixty-nine gener...

A relationship between aggressiveness and memory has been proposed in several studies with different animal species. Here, we study this possibility in the crab Chasmagnathus granulatus, using the context-signal memory model (CSM) that involves an association between the learning context and a visual danger stimulus. Each experiment consisted of an agonistic phase and a memory one. During the f...

The requirement for IL-4 to promote differentiation of naive CD4(+) T cells into T(h)2 effector cell populations was established by classical in vitro studies. More recent in vivo data, however, indicate that signaling through the IL-4R is not essential for acquisition of the T(h)2 phenotype. In order to reconcile these seemingly contradictory conclusions, we have taken advantage of the ability...

In heterokaryons between senescent and young diploid fibroblast-like cells, dominance of the former with respect to nuclear DNA synthesis (incorporation of [(3)H]thymidine) was demonstrated. For identification of the respective partners, double-layer autoradiography was used after the old cells were labeled with [(3)H]methionine and the young cells were labeled with [(14)C]thymidine. Synchrony ...

Reaction pathways that bypass the conventional saddle-point transition state (TS) are of considerable interest and importance. An example of such a pathway, termed "roaming," has been described in the photodissociation of H(2)CO. In a combined experimental and theoretical study, we show that roaming pathways are important in the 308-nm photodissociation of CH(3)CHO to CH(4) + CO. The CH(4) prod...

Indirect estimates of the genomic rate of deleterious mutations (lambda), their average homozygous effect (s) and their degree of dominance (h) can be obtained from genetic parameters of natural populations, assuming that the frequencies of the loci controlling a given fitness trait are at mutation-selection equilibrium. In 1996, H.-W. Deng and M. Lynch developed a general methodology for obtai...

In order to study the inheritance of some traits related to grain yield in drought stress conditions in bread wheat (Triticum aestivum L.), F2, F3 and F4 generations derived from a Kharchia (tolerant) × Gaspard (susceptible) cross and their parents were used separately in a complete randomized block design with two replications. Stem length, biological yield, main spike straw weight, total spik...

Electroconvulsive therapy (ECT) often results in a number of short- and long-time side effects including memory impairment for past and current events, which can last for several months after ECT treatment. It has been suggested that unilateral ECT (uECT) with electrodes placed over the non-dominant (typically right) hemisphere significantly reduces side effects, especially memory disturbances....
