boron (b) toxicity is an important disorder that can limit plant growth in arid and semi-arid environments. it has been proven that use of tolerant rootstocks impede b uptake or transport to the aerial portions of plants. this may alleviate b toxicity in the scion, consequently improves the tolerance to excess b in the root zone. an experiment was conducted to find the effects of b toxicity on ...

The primate neocortex is characterized by a highly expanded supragranular layer (SGL). The interareal connectivity of the neurons in the SLG largely determines the cortical hierarchy that constrains information flow through the cortex. Interareal connectivity is made by precise numbers of connections, raising the possibility that the physiology of a target area is dictated by the numbers of con...

This study focused on the predictive contributions of infants’ temperamental negative emotionality (proneness to fear, anger), sex, maternal responsivity, and their interaction on toddlers’ empathy-related responding to distress in 3 contexts. Ninety-eight infants and their mothers participated in a longitudinal study. When the infants were 10 months of age, mothers completed assessments of inf...

PURPOSE Effective communication between physicians and adolescents is critical to convey health information, provide counseling and identify emerging health problems. This article addressed two questions: (a) After an adolescent enrolls in a State Children's Health Insurance Program (SCHIP), is there a change reported in communication between the adolescent and his/her health care provider; and...

A puzzle has emerged from studies examining the wage effects of sexual orientation for women. Although lesbian and bisexual women face discrimination in the labor market, most studies of the wages of female full-time workers in same-sex couples versus those in different-sex couples find that the lesbians earn more, even controlling for differences in present labor market supply, education, year...

In recent years the neuropeptide oxytocin (OT) has become one of the most studied peptides of the human neuroendocrine system. Research has shown widespread behavioural effects and numerous potential therapeutic benefits. However, little is known about how OT triggers these effects in the brain. Here, we discuss some of the physiological properties of OT in the human brain including the long ha...

AIM The aim of this study is to investigate the effects of food insecurity derived from non-cereal food consumption on nutritional status of children and mothers in a poverty-prone region in Bangladesh. METHODS Data from the Bangladesh Nutritional Surveillance Project, 2005 of Helen Keller International were used to relate non-cereal food consumption and household food insecurity to nutrition...

Using data from a longitudinal surveillance study from rural South Africa, we investigated the odds of sexual debut, pregnancy and HIV infection of 15- to 19-year-old adolescents by parental survival. Using descriptive statistics and logistic regressions, we examine the relative risk of orphans compared with non-orphans to have ever had sex, being pregnant and being HIV infected, adjusting for ...
