Photoperiodic Effects on Seasonal Physiology, Reproductive Status and Hypothalamic Gene Expression in Young Male F344 Rats [PDF]
Journal of neuroendocrinology, 2015 Seasonal or photoperiodically sensitive animals respond to altered day length with changes in physiology (growth, food intake and reproductive status) and behaviour to adapt to predictable yearly changes in the climate.

Inbred F344 rats as a biologic model of intra-abdominal sepsis [PDF]
, 2002 Aiming to design a biologic model of acute intra-abdominal sepsis for experimental studies, conventional, isogenic rats F344 were infected with the bacteria Escherichia coli (E.coli), strain 11775, serotype H7:01:K1.

Effects of neonatal handling on play and anxiety in F344 and Lewis rats
Developmental Psychobiology, 2018 Play is an important part of normal childhood development and seen in many mammals, including rats. To better understand the interplay between genotype and postnatal experiences, the effects of neonatal handling on play were assessed in Lewis (LEW) and ...

Derivation of a germline competent transgenic Fischer 344 embryonic stem cell line. [PDF]
PLoS ONE, 2013 Embryonic stem (ES) cell-based gene manipulation is an effective method for the generation of mutant animal models in mice and rats. Availability of germline-competent ES cell lines from inbred rat strains would allow for creation of new genetically ...

Local vs. systemic administration of bisphosphonates in rat cleft bone graft: A comparative study. [PDF]
PLoS ONE, 2018 A majority of patients with orofacial cleft deformity requires cleft repair through a bone graft. However, elevated amount of bone resorption and subsequent bone graft failure remains a significant clinical challenge.

Experimental rat models of chronic allograft nephropathy: a review [PDF]
, 2014 Chronic allograft nephropathy (CAN) is the leading cause of late allograft loss after renal transplantation (RT), which continues to remain an unresolved problem. A rat model of CAN was first described in 1969 by White et al. Although the rat model of RT
