A slight modification in the method used to remove the top keratinized layer of skin in the epidermal scarification model of HSV infection results in an easier, less painful, more uniform and reproducible means of infection. The back of mice was…

Factors associated with a single bout of dynamic exercise (increased circulating catecholamines, increased body temperature, and decreased pH) are known to attenuate the vascular response to alpha-adrenergic receptor activation. Therefore, we…

Ischemic heart disease is still the leading cause of death even with the advancement of pharmaceutical therapies and surgical procedures. Early vascularization in the ischemic heart is critical for a better outcome. Although stem cell therapy has…

Research using animal models has contributed significantly to realizing the goal of understanding dysfunction and improving the care of patients who suffer from dysphagia. But why should other researchers and the clinicians who see patients day in…

HDL and apolipoprotein A1 (apoA1) concentrations inversely correlate with risk of death from ischemic heart disease; however, the role of apoA1 in the myocardial response to ischemia has not been well defined. To test whether apoA1, the primary HDL…

CGS 10746B, a dopamine release inhibitor with properties similar to the atypical antipsychotic clozapine, was assessed as to its behavioral properties using spontaneous locomotor activity and the conditioned place preference test. Rats conditioned…

The influence of daily spontaneous running (DSR) and gender on the arterial baroreflex regulation of heart rate (HR) and lumbar sympathetic nerve activity (LSNA) was examined in 13 male [7 sedentary (SED) and 6 DSR] and 12 female (6 SED and 6 DSR)…

The effect of daily spontaneous running on blood pressure homeostasis (BPH) was evaluated in 19 male and 13 female control rats and 7 male and 13 female daily spontaneous running rats subjected to surgery and subsequent repetitive hemodynamic…

Exercise training attenuates arterial baroreflex function. Mechanisms responsible may include an attenuated aortic baroreceptor reactivity (afferent mechanisms) and/or an attenuated central baroreflex gain. We tested the hypothesis that the aortic…

Exercise training alters the cardiopulmonary baroreflex regulation of the circulation; however, the mechanisms responsible are unknown. One possibility is an enhanced afferent response to cardiopulmonary stimulation. We therefore tested the…

The acoustic rearing environment can alter central auditory coding properties, yet altered neural coding is seldom linked with specific deficits to adult perceptual skills. To test whether developmental hearing loss resulted in comparable changes to…

The effects of gender and gonadal hormones on nociceptive responses to intraplantar carrageenan in the rat were investigated. A plantar analgesic meter was used to measure carrageenan-induced changes in paw withdrawal latency (PWL) values, and von…

STUDY DESIGN: A human growth hormone transgene was bred into mice of the Cola2oim (oim) lineage. Caudal (tail) vertebrae from male and female mice at early skeletal maturity and at midlife were evaluated for physical and biomechanical properties.…

Transient receptor potential vanilliod 1 (TRPV1) channels have recently been postulated to play a role in the vascular complications/consequences associated with diabetes despite the fact that the mechanisms through which TRPV1 regulates vascular…

Ovariectomized rats treated or not with an estradiol pellet were subjected to an unilateral intrastriatal infusion of 6-hydroxydopamine (6-OHDA). Various parameters of nigrostriatal dopaminergic function as derived from measurements of dopamine and…

In the mustached bat's central nucleus of the inferior colliculus (ICC), many neurons display facilitatory or inhibitory responses when presented with two tones of distinctly different frequencies. Our previous studies have focused on spectral…

The auditory cortex of the mustached bat (Pteronotus parnellii) displays some of the most highly developed physiological and organizational features described in mammalian auditory cortex. This study examines response properties and organization in…
