This study observed that albino rats, despite not producing melanin, have melanocytes localized in specific skin areas of their hair matrix, suggesting that gene expression analysis of their skin should consider regional differences in melanocyte presence.

This study reported that albino Wistar rats exposed to chemical hair straighteners showed significant hair fiber damage and scalp skin deterioration, which worsened with repeated and prolonged application, highlighting the cytotoxic potential of these products and potential systemic risks.

This study found that early postnatal androgen activity affects the long-term expression of hormone receptors differently in female Wistar rats, influencing neural system programming during development.

This research reports that paternal finasteride treatment in male rats may negatively impact liver function in their male offspring, as observed through altered expression patterns of ERα and PCNA in liver tissue across different developmental stages.

In this study, researchers used synchrotron X-ray imaging to examine rat vibrissa follicles, finding that despite variations in vibrissa length and follicle size, certain sensory structures remain consistent, suggesting specialized roles in sensory processing depending on the vibrissa type.

In this study with diabetic rats, the researchers found that combining Amoxicillin/Clavulanate with metformin may enhance the glucose-lowering effects of metformin, without affecting cholesterol, triglycerides, or certain electrolytes.

This study found that treating male rats with human hair follicle stem cells improved memory function impaired by streptozotocin and increased both neurotrophic and inflammatory markers, suggesting potential neuroprotective effects in this model.

In this study, researchers reported that standardized rosemary and capsicum extracts significantly improved hair growth parameters such as follicle density, length, and diameter in rats with testosterone-induced alopecia, suggesting these extracts may aid in more effective natural treatments for androgenetic alopecia.

This study found that mimosine in lamtoro leaf powder causes moderate congestion and mild necrotic lesions in the pancreas of white rats, which are less severe than those caused by standard mimosine, suggesting the leaf powder's flavonoid, tannin, and protein components may reduce mimosine toxicity.

In this study, female rats given high doses of testosterone showed decreased endometrial thickness and lower mRNA levels of components in the LIF signalling pathway, indicating that excessive testosterone may negatively impact endometrial receptivity and potentially affect fertility.

In this animal study, researchers reported that acetaminophen increased LH and FSH hormones in male rats, with high doses affecting sperm production negatively, while avocado leaf extract reduced sperm motility and viability, suggesting potential adverse effects on male reproductive health.

This study in adult male albino rats reported that human umbilical cord blood-derived mesenchymal stem cells were more effective than minoxidil in promoting hair growth for androgenic alopecia, observing superior outcomes in hair follicle metrics.

In this study on Wistar rats, ginger and celery extracts at the tested dosage did not significantly affect hair growth onset, duration, or regrowth, nor did they cause significant inflammation, despite the presence of bioactive phytochemicals in the extracts.

This study found that administering a supraphysiological dose of testosterone to female rats significantly reduced estrogen and progesterone levels, disrupted sex steroid receptor expression, and interfered with the embryonic implantation window, indicating potential implications for androgen-related endometrial conditions.

This study observed that in spontaneously hypertensive rats, testosterone's effects on endothelium-dependent vasodilation involved reduced nitric oxide levels, increased oxidative stress, and greater reliance on endothelium-dependent hyperpolarization, with variations in these responses noted when testosterone was combined with either anastrozole or finasteride.

In this study involving genetically modified rats, researchers observed that specific mutations in the vitamin D receptor affect calcium levels and bone formation, emphasizing the receptor's role in maintaining healthy bone density and its importance in regulating hair cycle and skin health.

This animal study found that finasteride, a 5-alpha reductase type 2 inhibitor, decreased dihydrotestosterone levels and c-Fos protein activation in the rat brain, but these effects may diminish after discontinuing the drug.

In this study on Sprague-Dawley rats, 0.60 mg/kg doses of L-Se-methylselenocysteine and sodium selenite were associated with liver toxicity and reduced sperm motility, while Se-enriched peptides showed no observable adverse effects up to 0.60 mg/kg.

This study found that polycaprolactone (PCL) in facial fillers led to more cell proliferation and vascular activity than hyaluronic acid (HA) in Wistar rats, suggesting enhanced tissue regeneration effects with PCL.

Aloe vera extract helps heal burn wounds faster in rats.

Aloe vera may help heal burns by boosting skin cell growth.

This study found that Wistar rats fed with grass extracts from mining areas accumulated trace metals, particularly in the spleen, leading to organ pathology and signs of toxicity.

In this study, the administration of indole-based compounds, particularly L-Tryptophan and Tryptophol, to a PCOS-induced rat model resulted in an increased number of healthy ovarian follicles and a reduction in ovarian cysts compared to untreated rats, suggesting potential therapeutic efficacy.

In this study, PRP improved capillary formation and increased hair follicle density after hair transplantation in rats, suggesting it may enhance the success of such procedures.

Finasteride improved reflexes and motor activity in rats with liver-related brain issues.

This study found that in a rat model of alopecia, combining low-level laser therapy with Neoptide treatment resulted in better hair regrowth compared to either treatment used alone.

This study found that in male rats, finasteride significantly decreased spermatogonia and primary spermatocytes numbers and increased Leydig cells, but did not affect overall testis histology or spermatogenesis.

Vitamin B can prevent hair from turning gray in rats.

This study found that in male rats, chronic finasteride treatment reduced allopregnanolone levels, which, upon drug withdrawal, correlated with increased pro-inflammatory cytokines and altered neurotransmitter levels.
