Recent studies have shown that glucocorticoids may have modulatory effect on anxiety reactions. This effect may occur with opioid system interference. According to that, the purpose of this research is to assess the effect of dexamethasone as glucocorticoid agonist and its interaction with opioidergic system on the anxiety modulatory effect in plus maze model in mice. Male white mice with mediu...

BACKGROUND Biologic factors are known to contribute to asthma severity. It is unknown whether these factors differentially contribute to asthma severity in black compared with white subjects. OBJECTIVE We sought to assess the extent to which racial disparities between black and white subjects with severe asthma are attributable to physiologic, immunoinflammatory, and sociodemographic variable...

The objectives of this study were to investigate color patterns of shell and mantle edge pigmentation of a Pacific oyster, C. gigas, and to estimate variance components of the two colors. A sample of 240 F0 oysters was collected from six aquaculture farms in Tongyeong, Korea to measure shell color and mantle edge pigmentation. Among the F0s, male and female individuals with black (white) shell ...

Three studies examined the implicit evaluative associations activated by racially-ambiguous Black-White faces. In the context of both Black and White faces, Study 1 revealed a graded pattern of bias against racially-ambiguous faces that was weaker than the bias to Black faces but stronger than that to White faces. Study 2 showed that significant bias was present when racially-ambiguous faces ap...

Using a national sample of 1,461 child protective services (CPS) investigations in the United States, we examine differences between black and white families with regard to caseworker ratings of risk and harm to the child, as well as the probability that a case is substantiated for maltreatment. We employ difference-in-difference methods to identify whether gaps in outcomes for black and white ...

BACKGROUND The long-term predictive significance of a single ECG tracing for mortality was explored among the white and black men of the Charleston Heart Study. METHODS AND RESULTS The 1960 baseline tracings of men ages 35 to 74 in the Charleston Heart Study cohort were coded according to the Minnesota classification. Tracings were categorized as being normal or having minor or major abnormal...

The color of the blends of pre-colored fibers depends on the ratio of each fiber in the blends. Some theories have been introduced for color matching of blends of pre-colored fibers. Most however, are restricted in scope and accuracy. Kubelka and Munk presented the most applicable theory, which is still used in industry. In this work, the classical Kubelka-Munk method for color prediction of a ...

Despite growing racioethnic diversity in U.S. organizations, few organizational studies have focused on Black-White interracial interactions. Two experiments examined the influence of interaction roles, and the social scripts they trigger, on White participants' anxiety during dyadic interactions with Black partners. Results from both studies reveal that White participants exhibited greater dis...

research is necessary for adjust and improve the process of land degradation in the agricultural, horticultural and also prevent the formation of spatial patterns is uneven and sporadic. the present study sought to analyze the impact of the components of the population (population change and population density) and development land on the spatial pattern of sprawl in the study area. in this pap...

OBJECTIVE The objective of this study was to make use of a quantitative and qualitative approach comparing the systemic renin-angiotensin system (RAS) of hypertensive black and white African men by using RAS equilibrium analysis. MATERIALS AND METHODS This sub-study involved 23 black (n = 15) and white (n = 8) hypertensive men aged 39.5-41 years, living in the North West Province of South Afr...
