Purpose: To investigate whether autologous platelet-rich plasma (PRP) treatment can improve regeneration of the endometrium in an experimental model of ethanol-induced damage.
Materials And Methods: Sixty female Sprague-Dawley rats were randomly assigned into three groups: control group, ethanol group, and PRP-treated group (administration of 0.25 mL of PRP into both uterine cavities 72 hours after ethanol injection). After 15 days of endometrial damage, all the animals were sacrificed during the estrous cycle, and samples were taken from the mid-uterine horn. Functional and structural recovery of the endometrium was analyzed by hematoxylin-eosin (H&E) and Masson trichrome (MT) staining, real-time polymerase chain reaction (PCR) assay, and immuno-histochemical (IHC) analyses.
Results: H&E and MT staining confirmed significantly decreased fibrosis and increased cellular proliferation in the PRP-treated group, compared to the ethanol group. The endometrial areas in the ethanol and PRP-treated groups were 212.83±15.84 μm² and 262.34±12.33 μm² (p=0.065). Significantly stronger IHC expression of cytokeratin, homeobox A10 (HOXA10), vascular endothelial growth factor (VEGF), and Ki-67 was found in the PRP-treated group, compared to the ethanol group. In real-time PCR analyses, interleukin-1β mRNA was down-regulated, while c-Kit mRNA was up-regulated, in the PRP-treated group, compared to the ethanol group.
Conclusion: Intrauterine administration of autologous PRP stimulated and accelerated regeneration of the endometrium and also decreased fibrosis in a murine model of damaged endometrium.

Polycystic ovary syndrome (PCOS) is a common cause of infertility in women, characterized by metabolic and hormonal irregularities. We investigated the effects of placenta-derived mesenchymal stem cells (PDMSCs) and platelet-rich plasma (PRP), as well as their combination on follicular development, hormonal profile, inflammatory parameters, and insulin resistance in a model of PCOS. In this study, 25 female Wistar rats were randomly allocated into five groups: Sham (given a dose of 1 mL of a 0.

Article Synopsis
- Knee osteoarthritis (OA) is a slow progression of cartilage damage leading to pain and difficulties in movement, with standard pain medications not effective for everyone.
- A systematic review analyzed 10 studies from 2016-2023 on the use of platelet-rich plasma (PRP) injections for reducing OA pain compared to a placebo.
- While some studies showed significant improvement in symptoms for PRP-treated patients, results were inconsistent, indicating the need for more research to clarify PRP's effectiveness and consider other factors like follow-up times and patient conditions.
BIOFILLER VS PLATELET-RICH PLASMA MESOTHERAPY IN THE TREATMENT OF PERI-ORBITAL HYPERPIGMENTATION.

Article Synopsis
- Peri orbital hyperpigmentation (POH) is a common skin issue with various causes, and this study aimed to compare the effectiveness of Biofillers vs. Platelet-Rich Plasma (PRP) therapy in treating it.
- In a double-blinded randomized trial involving 42 patients, the results showed that Biofillers provided significant improvements in pigmentation, patient satisfaction, and had fewer side effects compared to PRP.
- The study concluded that Biofillers are a more effective and safer treatment option for POH than PRP therapy.

Rheumatoid arthritis causes inflammation, pain, and joint degradation, necessitating treatment with anti-inflammatory drugs and corticosteroids, posing various challenges. We aimed to evaluate the effects of photobiomodulation (PBM) at two different doses associated to platelet-rich plasma (PRP) in an in vivo model of induced acute arthritis in Wistar rats' knee. Eighty-four Wistar rats were assigned into seven groups, including animals treated with PBM and/or PRP.
