Article Synopsis
  • Polycystic ovary syndrome (PCOS) is a complex condition affecting hormones and metabolism, and the study investigates the impact of chlorogenic acid (CGA) on this disorder using a rat model.
  • The experiment involved 18 rats divided into three groups: a control group, a PCOS group without treatment, and a PCOS group treated with CGA, with various hormonal and ovarian analyses conducted thereafter.
  • Results showed that CGA treatment led to a significant decrease in certain hormones and cystic follicles while increasing the levels of others, suggesting CGA may beneficially influence follicular development and hormonal balance in PCOS-affected rats.

Article Synopsis
  • - The study explored how chlorogenic acid (CGA) can protect mouse testicular tissue from damage caused by ionizing radiation (IR) during pelvic cancer treatment.
  • - Seventy mice were used in an experiment where one group was exposed to IR alone, while others were treated with various doses of CGA after IR exposure, and their testes were analyzed later.
  • - Results showed that CGA, especially at 40 mg/kg, significantly reduced damage to sperm production and improved various biochemical markers, indicating that higher doses of CGA have better protective and therapeutic effects.

Background: Chlorogenic acid (CGA) is one of the well-known polyphenol compounds possessing several important biological and therapeutic functions. In order to optimize a culture system to achieve complete development of follicles, we focused on the effects of CGA supplementation during in vitro culture (IVC) on follicular development, oxidative stress, antioxidant capacity, developmental gene expression, and functional potential in cultured mouse ovarian tissue.

Methods And Results: The collected whole murine ovaries were randomly divided into four groups: (1) non-cultured group (control 1) with 7-day-old mouse ovaries, (2) non-cultured group (control 2) with 14-day-old mouse ovaries, (3) cultured group (experimental 1) with the culture plates containing only the basic culture medium, (4) cultured group (experimental 2) with the culture plates containing basic culture medium + CGA (50, 100 and 200 µmol/L CGA).

Article Synopsis
  • Skin flap necrosis poses a significant challenge in plastic surgeries, prompting research into potential treatments.
  • In a study with rats, three groups were given different doses of metformin after surgery to create a dorsal skin flap, with results showing improved survival rates in those treated with metformin.
  • The low dose of metformin not only increased skin flap survival but also enhanced blood vessel density and the expression of vascular endothelial growth factor (VEGF) in the tissues, indicating better healing.

Background: This study investigated the potential effects of Titanium dioxide nanoparticles (Tio2NPs) followed by maternal gavage on fetal development and neural tube formation during pregnancy in mice.

Methods: Thirty pregnant mice were randomly divided into five main study groups including the untreated control and 4 experimental groups (n=6 per group). The control group was treated with normal saline and the experimental groups were orally treated with doses of 30, 150, 300, and 500 Body Weight (BW) of Tio2NPs during pregnancy.

Aim: To investigate the effect of Propolis-gum Arabic as a nerve guidance channel.

Material And Methods: Male rats (n=24) were randomly divided into sham surgery, autograft, and Propolis+gum Arabic groups with equal numbers. Under anesthesia, the sciatic nerve was removed, and the gap between the two ending was repaired by Propolis-gum Arabic or nerve autograft.

Titanium dioxide particles (TiO) as the second most widely used materials in consumer products are composed of nano-sized (<100 nm) particles (NPs) and fine-sized (>100 nm) particles (FPs). Toxicological studies on animals have shown that TiO NPs exposure can cross the blood-testis barrier and accumulate in the testis resulting in testicular tissue damage and reduction of sperm count and motility. However, there is no information on the toxic effects of TiO FPs on male reproductive fertility.

Background: The production of stress oxidative condition in body which is caused by consumption of ecstasy (3,4-methylenedioxymethamphetamine [MDMA]) leads to a liver damage. As an antioxidant, Vitamin E can protect cells and tissues against the deleterious effects of free radicals. This study evaluates the protective effects of Vitamin E on MDMA induced liver toxicity.

Article Synopsis
  • The study investigates the effects of long-term exposure to low doses of pesticide mixtures on rats, assessing changes in behavior, brain structure, and function.
  • Male Wistar rats were exposed for 90 days to different doses of a mixture of five pesticides, revealing that higher doses caused significant harmful effects on the nervous system.
  • Even at the legally permitted levels, medium doses led to oxidative stress and memory impairment, indicating that pesticide mixtures can be harmful in ways not currently understood.

Fluoxetine is a selective serotonin reuptake inhibitor is commonly prescribed to treat maternal depression in pregnancy and lactation. This study aimed to investigate the effects of maternal exposure to fluoxetine via lactation on testicular tissue, sperm parameters including count, motility, viability, and normal morphology and testicular oxidative stress status in male mice offspring. Ten mice dams were divided into control and experimental groups.

In this study, we investigated the potential of thymol and its mode of action to protect against the titanium dioxide (TiO) nanoparticle-induced testicular damage. Twenty-four rats were randomly divided into four groups: control group, TiO (100 mg/kg BW/day) group, TiO + thymol (10 mg/kg BW/day) group, and TiO + thymol (30 mg/kg BW/day) group. With the exception of the control group, all animals received orally TiO nanoparticles for 60 days.

Previous studies proved the pro-angiogenic effect of Crocetin, a natural carotenoid dicarboxylic acid, in both and models. However, the exact mechanism of Crocetin action has not completely been elucidated yet. The current experiment was designed to find the activity of PI3K-Akt-eNOS axis after the treatment of endothelial cells with Crocetin .

  • This study aimed to assess the impact of various remote ischemic preconditioning (RIPC) techniques on spinal cord injury caused by ischemia-reperfusion in rats.
  • A total of 36 rats were divided into six groups, and different RIPC methods were applied before inducing spinal cord ischemia, with evaluations conducted 72 hours post-injury to measure neurological function and tissue damage.
  • The findings indicated that RIPC methods involving both hind and/or fore limbs improved motor function, reduced oxidative stress markers, and minimized white matter damage compared to the control group, suggesting these techniques offer protective benefits against spinal cord ischemic injuries.
