Lack of efficacy of blueberry in nutritional prevention of azoxymethane-initiated cancers of rat small intestine and colon

BMC Gastroenterology, 2009
Background Blueberries may lower relative risk for cancers of the gastrointestinal tract. Previous work indicated an inhibitory effect of consumed blueberry (BB) on formation of aberrant crypt foci (ACF) in colons of male Fisher F344 rats (inbred strain).

Local vs. systemic administration of bisphosphonates in rat cleft bone graft: A comparative study.

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.

Cutaneous photosensitivity of phototheranostic porphyrin–lipid nanoparticles

Photochemistry and Photobiology, Volume 101, Issue 6, Page 1541-1558, November/December 2025.
Porphyrin‐lipid nanoparticles (PORPHYSOMES) exhibit significantly less severe and shorter‐lasting skin photosensitivity to sunlight compared to a therapeutically equivalent dose of porfimer sodium (PHOTOFRIN) in a rat skin model. The difference was due to altered intradermal distribution and faster clearance of PORPHYSOMES from skin after intravenous ...

Organ Specificity and Commonality of Epigenetic Aging in Low‐ and High‐Running Capacity Rats

Aging Cell, Volume 24, Issue 8, August 2025.
Cardiorespiratory fitness (CRF) is not associated with epigenetic clocks, including newly developed ones. On the other hand, CRF is associated with global methylation profiles and promoter methylation in organ‐specific and organ‐common manner. ABSTRACT Epigenetic drift, which is gradual age‐related changes in DNA methylation patterns, plays a ...

Oxidative Stress in People Living With HIV: Are Diverse Supplement Sources the Solution?

Health Science Reports, Volume 8, Issue 5, May 2025.
ABSTRACT Background and Aim Antiretroviral therapy (ART) has reduced human immunodeficiency virus (HIV)/AIDS to a manageable chronic condition even though no cure exists. Despite ART control, latent HIV infection results in failed memory CD4 T‐cell responses, immune overactivation, inflammation, oxidative stress, genomic instability, deoxyribonucleic ...

Photoperiod influences visceral adiposity and the adipose molecular clock independent of temperature in wild‐derived Peromyscus leucopus

FASEB BioAdvances, Volume 7, Issue 5, May 2025.
Physiology is closely synchronized to daily and seasonal light/dark cycles. Wild‐derived white‐footed mice were housed in long‐day (LD – 16L:8D) or short‐day (SD – 8L:16D) photoperiods at thermoneutrality (27°C). LD selectively increased visceral WAT mass and decreased Adrβ3 and Ucp1 expression while inducing misalignment of clock genes compared to SD.

Gene-dosage- and sex-dependent differences in the prodromal-Like phase of the F344tgHD rat model for Huntington disease

Frontiers in Neuroscience
In Huntington disease (HD) the prodromal phase has been increasingly investigated and is currently in focus for early interventional treatments. Also, the influence of sex on disease progression and severity in patients is under discussion, as a sex ...

Studies on transplantability of four strains of osteosarcoma in inbred F344 rats and successiveness of their bone-forming character.

Japanese Journal of Oral & Maxillofacial Surgery, 1991
A number of transplantable animal models of osteosarcoma have been developed so far, but the available strains of the rat that keep their bone-forming ability through many serial transplantations are limited both in the number of strains and their applicability.

Genetic Loci Influencing Cue‐Reactivity in Heterogeneous Stock Rats

Genes, Brain and Behavior, Volume 24, Issue 2, April 2025.
A genome‐wide association study characterizing individual differences in cue‐reactivity (sign‐tracking; A) identifies multiple genetic loci, particularly on chromosomes 1 and 18 (B). Multiple candidate genes in these regions were identified, including those with known psychiatric relevance (e.g., Tenm4; C) and novel candidates with heritable ...

Risks to human and animal health from the presence of bromide in food and feed

EFSA Journal, Volume 23, Issue 1, January 2025.
Abstract The European Commission mandated EFSA to assess the toxicity of bromide, the existing maximum residue levels (MRLs), and possible transfer from feed into food of animal origin. The critical effects of bromide in experimental animals are on the thyroid and central nervous system.
