The development of new technologies and industry increases the number and variety of electromagnetic field (EMF) sources. Researcher are increasingly interested in the effects of EMF on brain health. The brain's function is largely dependent on electrical excitability, so it would be expected to be vulnerable to EMF. We therefore investigated the effects of brain development in the fetus, histopathological changes in female rats and the hippocampal level of MAPK proteins in male rats after exposed to pre and postnatal 2450 MHz continuous wave (CW) radiofrequency radiation (RFR) over four generations. Four groups; sham, irradiated female, irradiated male, irradiated male and female, with each consisting of four rats (one male and three females) were created. Rats in the exposure groups were whole-body exposed to 2450 MHz CW-RFR for 12 h/day during the experiment. Irradiation started one month before fertilization in the experimental group. On the 18th day of the gestational period, one pregnant rat from each group was decapitated under general anesthesia and the fetuses were taken. The remaining two pregnant rats completed the normal gestation period. When the offspring were two months old, four rats, one male and three female, were allocated for the second generation study. Next generation animals were also experienced the same processes as the first generation rats. This study were evaluated development of brain in fetuses and histopathological changes in brain of female rats using haematoxylin eosin staining, and the hippocampal level of MAPK proteins in brain of male rats by Western Bloting. We observed hemorrhagic areas, irregular cellular localization and vascular structures in the brain of fetal and adult female rat of exposed groups in the all generations. pERK, ptau, pJNK and pP38 were increased in the brain of adult male rat of exposed groups in the all generations (p < 0.005). Pre and postnatal 2450 MHz continuous wave radiofrequency radiation exposure may cause changes in the function of the MAPK pathway affecting cognitive processes such as learning and memory and may cause damage to both the fetus and adult brain tissue. Also, EMF may have potential to affect brain of future generations.

Background: Diabetes poses a risk to diabetic keratopathy in up to two-thirds of patients. Insulin-degrading enzyme (IDE) is a protease that can break down insulin and several growth factors and may impair wound healing. Increased IDE levels have been found in fluid from diabetic skin ulcers.

Background: The cannabinoid type 2 receptors (CB2R) represent a target of increasing importance in neuroimaging due to its upregulation under various neuropathological conditions. Previous evaluation of [F]JHU94620 for the non-invasive assessment of the CB2R availability by positron emission tomography (PET) revealed favourable binding properties and brain uptake, however rapid metabolism, and generation of brain-penetrating radiometabolites have been its main limitations. To reduce the bias of CB2R quantification by blood-brain barrier (BBB)-penetrating radiometabolites, we aimed to improve the metabolic stability by developing -d and -d deuterated isotopologues of [F]JHU94620.

Diabetes Mellitus is a metabolic disorder characterized by high blood glucose levels, causing significant morbidity and mortality rates. This study investigated the antidiabetic, neuroprotective, and antioxidant effects of ethanol extracts of Parkia biglobosa (PB) leaves and seeds in streptozotocin (STZ)-induced diabetic rats. The administration of STZ significantly elevated fasting blood glucose levels (FBGL) to 355-400 mg/mL compared to 111 mg/mL in normal controls, indicating hyperglycemia.

Background: Bile salts enriched nanovesicles (bilosomes) have been attention worthy in the past few years due to their distinctive effect on the enhancement of drug delivery through various physiological administration routes. Oral delivery of multifunctioning phytochemical curcumin has faced a lot of difficulties due to its scarce solubility and poor oral bioavailability.
Objective: The current investigation aimed to develop curcumin loaded bilosomes for improvement of oral curcumin bioavailability with maximum efficiency and safety.

Exposure to potassium dichromate (KCrO) is well known for its nephrotoxic effects on humans and animals. This study investigated the protective effects of vitamin C against KCrO-induced nephrotoxicity, focusing on its impact on altered carbohydrate metabolism, mitochondrial dysfunction, and associated molecular mechanisms in the cortical and medullary kidney segments. Male Wistar rats (n = 8) were divided into four groups: Group I received saline, Group II received a single 250 mg/kg body weight (bwt) intraperitoneal (i.
