Effect of Rat Strain Stereotactic Coordinates on Infarct Volume
… treatment for these cases is intravenous administration of tPA within a 3.5 hour window from stroke onset. A long-term delayed ischemic stroke treatment proposed by this study was a combination of the pharmaceuticals Fluoxetine (SSRI), Simvastatin (statin), and ascorbic acid (Vitamin C). 51 adult …

Network mechanisms underlying susceptibility to helplessness and response to the antidepressant fluoxetine
… stress exposure using a stress-susceptible rat strain, 2) to identify the neural network effects of response and non-response to SSRI treatment using a stress-susceptible animal model, and 3) to determine the neurophysiologic correlates of helplessness susceptibility. This was examined via …

FROM DISEASE TO THE GENE - Identification of arthritis-regulating loci in rats
… towards various arthritis models of two DA rat substrains. We detected several genetic and phenotypic differences, suggesting that one of the substrains had been genetically contaminated from another rat strain. The second study is based on the observation that a spontaneous mutation in our …

Ubiquitin Conjugase UBE2K Is Essential for Normal Rat Development and Spermatogenesis
… early 1980's [Reviewd by (Hamra, 2010)], the laboratory mouse has emerged as the most widely published animal model in science (NCBI, PubMed). Interestingly, prior to the year 2000, annual publications in the laboratory rat outnumbered annual publications in the mouse by greater than 2-3 fold in …

Circulating sex hormone levels in rats: a systematic analysis of the literature and perinatal BPA study
… a systematic analysis of the available literature to characterize within the rat model how three different, popular outbred strains (Wistar, Sprague-Dawley, and Long-Evans) may each possess distinct levels of basal peripheral testosterone (T), estradiol (E2), or progesterone (P4) levels, …

Modulation of the T cell response with MHC class I peptides and their analogues
… stages of organ failure. It has been demonstrated that transplantation between genetically non-identical individuals leads to the activation of the recipient’s alloimmune response as a major determinant of transplant outcome. T cell recognition of foreign MHC molecules plays a key role in …

Physikalische Kartierung der RT1-C/M-Region des Haupthistokompatibilitätskomplexes der Ratte
The rat is an important model for studying organ graft rejection and susceptibility to certain complex diseases. The MHC, the RT1 complex, plays a decisive role in controlling these traits. During this work is cloned the telomeric class I region of the RT1 complex, RT1-C/E/M, of the BN inbred rat …

Effects of Aerobic Capacity Phenotype on Adaptive Responses to Ischemic Stress
… of the vascular network to sustain substrate delivery and adaptive responses within affected tissue to sustain function despite diminished substrate availability. Active aerobic exercise has been shown to improve both vascular and metabolic remodeling within and around ischemic tissues. …

Aging and Sympathetic Neurotransmission in Two Strains of Rats that Differ in Longevity and Immune Profiles
… established. From previous studies in Fischer rats (F344), we have found that during middle age, sympathetic nerve activity (SNA) rises in the spleen followed by a decline in noradrenergic (NA) innervation. Also, increased sympathetic signaling via betaadrenergic receptor (β-AR) and reduced …

Deciphering host-parasite molecular networks mediating resistance to toxoplasma gondii
… and prophylactic agents against T. gondii. Rats, like immunocompetent humans, develop a chronic infection, but vary in their susceptibilities to T. gondii infection depending on the rat strain. Compared to the T. gondii-susceptible Brown Norway (BN) rat, the Lewis (LEW) rat is extremely …

The role of norepinephrine in arousal and attention: a human and rat study
… the LCNE system to enhance the signal-to-noise ratio in stimulus-related neural networks. In addition terminal release of NE from LC neurons responds synergistically with glutamate release from glutamatergic neurons, thereby potentiating its signal. The Yerkes and Dodson (1908) theory of arousal …
