Risk Homeostasis Theory (RHT) suggests that changes made to the intrinsic risk of environments are negated in one of three ways: behavioural adjustments within the environment, mode migration, and avoidance of the physical risk. To date, this three-way model of RHT has little empirical support, whilst research findings on RHT have at times been diametrically opposed. A reconciliation of apparen...

BACKGROUND Congenital Brown syndrome is characterized by limited elevation particularly during adduction. The pathogenesis of congenital Brown syndrome is still controversial. CASE PRESENTATION A 6-year-old boy had been tilting his head to the left since infancy. He showed right hypertropia (RHT) of 2 prism diopters (Δ) in the primary position. He showed RHT 6Δ in right gaze, RHT 2Δ in left g...

OBJECTIVE To understand the prevalence and correlates of rapid HIV antibody testing (RHT) among men who have sex with men (MSM) clients of gay bathhouses. DESIGN Cross-sectional questionnaire survey. SETTING This study was conducted in a gay bathhouse in Hangzhou, China. PARTICIPANTS 354 MSM were validly recruited from October to December 2012. Inclusion criteria were (1) men who visited ...

BACKGROUND Parental height data are essential in the assessment of linear growth in children. A number of studies have documented inaccuracy in self-reported adult height. AIMS To determine whether there is a tendency for men to overestimate and women to underestimate their height. METHODS Heights of parents of children attending outpatient clinics were measured (MHt) and compared with repo...

OBJECTIVE In left ventricular hypertrophy (LVH) due to systemic hypertension, myocardial fibrosis is an important determinant of pathologic hypertrophy. Therefore, it is most relevant to utilize an antihypertensive regimen that permits a regression in myocardial fibrosis along with blood pressure normalization and regression of LVH. METHODS To address this issue we examined 60 Sprague-Dawley ...

Moldavan, Mykhaylo G., Robert P. Irwin, and Charles N. Allen. Presynaptic GABAB receptors regulate retinohypothalamic tract synaptic transmission by inhibiting voltage-gated Ca channels. J Neurophysiol 95: 3727–3741, 2006; doi:10.1152/jn.00909.2005. Presynaptic GABAB receptor activation inhibits glutamate release from retinohypothalamic tract (RHT) terminals in the suprachiasmatic nucleus (SCN)...

As a nondestructive geophysical tool, Ground penetrating radar (GPR) has been applied in tree root study in recent years. With increasing amounts of GPR data collected for roots, it is imperative to develop an efficient automatic recognition of roots in GPR images. However, few works have been completed on this topic because of the complexity in root recognition problem. Based on GPR datasets f...

BACKGROUND The aim of this study was to analyze stable hypertrophied myocardial function and its response to inotropic maneuvers in rats submitted to renovascular hypertension for a 10-week period (RHT group, n=10). MATERIAL/METHODS Myocardial performance was studied in isolated left ventricle papillary muscles in isometric contraction under the following conditions: at postrest contraction o...

Theoretical investigations of CO2 sorption are performed in four members of the highly tunable rht-metal-organic framework (MOF) platform. rht-MOFs contain two Cu(2+) ions that comprise the metal paddlewheels and both are in chemically distinct environments. Indeed, one type of Cu(2+) ion faces toward the center of the linker whereas the other type faces away from the center of the linker. Elec...

Radiative heat transfer (RHT) between macroscopic bodies at separations that are much smaller than the thermal wavelength is ruled by evanescent electromagnetic modes and can be orders of magnitude more efficient than its far-field counterpart, which is described by the Stefan-Boltzmann law. In this Letter, we present a microscopic theory of RHT in van der Waals stacks comprising graphene and a...
