The analgesic efficacy of morphine varies with rat strain and experimental pain model: implications for target validation efforts in pain drug discovery [PDF]

open access: yes, 2019
BACKGROUND: Translating efficacy of analgesic drugs from animal models to humans remains challenging. Reasons are multifaceted, but lack of sufficiently rigorous preclinical study design criteria and phenotypically relevant models may be partly ...

Anhedonia and other reward-related deficits in animal models of psychiatric disorder [PDF]

open access: yes, 2015
New insights have revealed the complex and heterogeneous nature of reward-related behaviours: not only are different aspects of reward (e.g. reward 'liking' and 'wanting') subserved by dissociable neural mechanisms, but they are differentially ...

Rat strains differ in antibody response to Streptobacillus Moniliformis

open access: yes, 2010
Rats are the natural host of Streptobacillus moniliformis. The bacterium is zoonotic which is an obvious reason for periodic monitoring of rat colonies for S. moniliformis infection.

Behavioral reactivity in spontaneously hypertensive rats

open access: yes, 1985
Spontaneously hypertensive rats of the Okamoto strain (SHR) were compared with inbred normotensive rats of the Wistar-Kyoto strain (WKY) and with normally bred Wistar rats (NT) in tests on the audiogenic immobility reaction (freezing), open-field ...

Effects of dietary mg status and susceptibility to hypertension on in-vitro lipid peroxidation in rats

open access: yes, 2002
This study was designed to determine the association between dietary Mg (Mg) status on induction of hypertension in both normotensive Wistar-Kyoto rats (WKY) and spontaneously hypertensive rats (SHR).

Genotype-dependent responsivity to inflammatory pain: A role for TRPV1 in the periaqueductal grey

open access: yes, 2019
Negative affective state has a significant impact on pain, and genetic background is an important moderating influence on this interaction. The Wistar-Kyoto (WKY) inbred rat strain exhibits a stress-hyperresponsive, anxiety/depressive-like phenotype and ...

Physiological and behavioral effects of d-threo-methylphenidate hydrochloride in male Wistar-Kyoto and spontaneously hypertensive rats

open access: yes, 2003
Millions of children and adults worldwide are diagnosed with Attention-deficit hyperactivity disorder (ADHD) and yet its very existence, definition, and treatment are surrounded with discord and controversy.

Psychoneuroendocrine profile associated with hypertension or hyperactivity in spontaneously hypertensive rats

open access: yes, 1993
The behavioral and neuroendocrine reactivity to a novel environment (open field) and the adrenocorticotropic hormone (ACTH)/corticosterone response to a corticotropin-releasing factor (CRF) challenge were measured in 2-mo-old rats from four inbred ...

Strain and site dependence of polyploidization of cultured rat smooth muscle

open access: yes, 1986
Smooth muscle cell (SMC) growth may play an important role in the pathogenesis of vascular diseases such as atherosclerosis and hypertension. Recent studies have demonstrated that, under different growth stimuli in vivo, SMC may respond by proliferation ...

Distinct QTLs are linked to cardiac left ventricular mass in a sex-specific manner in a normotensive inbred rat intercross

open access: yes, 2005
Genetic mapping of the progeny of an F2 intercross between WKY and WKHA rats had previously allowed us to detect male-specific linkage between locus Cm24 and left ventricular mass index (LVMI).
