Abstract This study intends to estimate the coefficient of repeatability for traits relating yield, so as infer what is minimum number evaluations required identify superior genotypes; verify adaptability and stability; predict genetic gains; select best families in S1 progenies Psidium guajava. Families were obtained by means self-fertilization genotypes (full sibs) from guava tree breeding pr...
Pollen limitation affects plants with diverse reproductive systems and ecologies. In self-incompatible (SI) species, pollen limitation may preclude full reproductive compensation for prezygotic rejection of pollen. We present a model designed to explore the effects of incomplete reproductive compensation on evolutionary changes at a modifier locus that regulates the level of SI expression. Our ...
Genetic and receptor interference data have indicated the presence of one or more cellular receptors for subgroup B, D, and E avian leukosis viruses (ALV) encoded by the s1 allele of the chicken tvb locus. Despite the prediction that these viruses use the same receptor, they exhibit a nonreciprocal receptor interference pattern: ALV-B and ALV-D can interfere with infection by all three viral su...
objective(s): asthma results from the interaction between genetic and environmental factors. adam33 gene on chromosome 20p13 is associated with asthma and airway hyperresponsiveness. materials and methods: this is a case-control study, where four snps s1 (rs3918396), t1 (rs2280091), t2 (rs2280090), v4 (rs2787094) of adam33 gene have been assessed in patients with allergic asthma and normal cont...
Objective(s): There are controversial results regarding the effect of the interaction of CETP polymorphisms with dietary fats on the lipid profiles. The aim of this study was to examine the effect of CETP polymorphisms (rs5882 and rs3764261) and macronutrient intakes interaction in relation to metabolic syndrome (MetS) or its components.Materials and Methods: In this nested case-control study, ...
This study examined behavioral and neuroelectric intra-individual variability (IIV) in preadolescent children during a task requiring variable amounts of cognitive control. The current study further examined whether IIV was moderated by aerobic fitness level. Participants performed a modified flanker task, comprised of congruent and incongruent arrays, within compatible and incompatible stimulu...
Reduction of virginiamycin S with sodium borohydride produces allo- and normal-dihydro-virginiamycin S. Reduction of the tosylhydrazone of virginiamycin S with sodium cyanoborohydride affords deoxyvirginiamycin S. These compounds are less active than virginiamycin S. Like virginiamycin S they enhance the activity of virginiamycin M1.
We studied a 43 yr-old Spanish patient with homozygous 4.1(-) hereditary elliptocytosis. Any form of protein 4.1 was missing in the red cells. Spectrin and actin were slightly, yet significantly, diminished. Alterations appeared at the level of proteins 4.5 and 4.9. Glycophorin C was sharply reduced. The abnormal allele was associated with the -++-- haplotype (Pvu II, Bgl II, Bgl II, Pvu II, Pv...
OBJECTIVE To investigate error and reaction time consequences of alternating compatible and incompatible steering arrangements during a simulated obstacle avoidance task. BACKGROUND Underground coal mine shuttle cars provide an example of a vehicle in which operators are required to alternate between compatible and incompatible steering configurations. METHODS This experiment examines the p...
Allium cepa bulbs were grown in pure tap water (group I), in seven concentrations of acetaminophen (7.81, 15.62, 31.25, 62.50, 125, 250, 500, and 1000 ppm) in the presence (group II) and absence of myrobalan (fruit of Terminalia chebula) at a fix concentration of 0.10 mg/mL. Parameters of study were mean root length, mitotic index, abnormal mitosis and chromosomal aberrations and morphology of ...
