Purpose: Breast cancer among Emirati patients is characterized by early-onset disease and later stages at presentation. Little is known about the germline genetic variants that may contribute to these observations. The goal of this study is to characterize the rate and implications of germline genetic variants among a cohort of Emirati patients at risk for hereditary breast and ovarian cancer syndrome.

Ultraviolet C (UVC) devices are an effective means of disinfecting surfaces and protecting medical tools against various microbes, including coronavirus. Overexposure to UVC can induce oxidative stress, damage the genetic material, and harm biological systems. This study investigated the prophylactic efficacy of vitamin C and B12 against hepatotoxicity in UVC-intoxicated rats.

Background: Cyclophosphamide (CP) (Cytoxan or Endoxan) is an efficient anti-tumor agent, widely used for the treatment of various neoplastic diseases. The study aimed to investigate the protective role of vitamin E (vit E) in improving cardiotoxicity in rats induced by CP.

Materials And Methods: Forty male Wistar rats were divided randomly into four experimental groups (each consisting of ten rats); the control group was treated with saline.

As one of the most exonerative, competitive, and abundant nanoparticles in curative uses, silver nanoparticles (AgNPs) play a growing important role in developing global neurodegeneration. Herein, we inspected the neurotoxic and histopathological effects of the oral dose of 26.9 nm citrate-coated AgNPs (100 and 1000 mg/kgbw, 28 days) on the brain conductivity and permittivity combined with neurotransmitter assays.

Microglial in vivo production of pro-inflammatory cytokines is central to the pathogenesis of multiple neurological disorders including depression, with a rising role of Wnt/β-catenin signaling as potential regulator of microglia-mediated neuro-inflammation. This study aimed at investigating the hippocampal expression of the Wnt/ß-catenin pathway in chronic mild stress (CMS)-exposed rats and the effects of Lithium (Li) on the expression of this pathway as a method to identify a plausible link between exposure to chronic stress, microglial activation, and neuroinflammation. METHODS: The effect of chronic administration of Li was investigated on behavioral changes, hippocampal expression of Wnt-DVL-GSK3β-β-catenin signaling pathway, and microglial activation in CMS-exposed male Wistar rats RESULTS: CMS induced a depressive-like behavior associated with increased pro-inflammatory microglial activation and reduced hippocampal expression of the Wnt/β-catenin signaling pathway.

Background: Due to renowned medicinal properties, Ginger rhizomes (Zingiber officinale Roscoe) used traditionally in the treatment of arthritis, rheumatism, muscular aches, constipation, indigestion, hypertension, dementia, fever, and infectious diseases. As an antiemetic, Ginger is consumed by approximately 80% of pregnant women to treat nausea and vomiting of early pregnancy.

Purpose: The aim of this study is to evaluate the impact of ginger extract on the oestrous cycle and implantation in female mice.

The present study was designed to evaluate the toxic effects induced by different time intervals of methomyl exposure on liver antioxidant defense system, oxidative stress, liver function biomarkers and histopathology in CD-1 mice. Ten male mice per group were assigned to one of four treatment groups. Group one served as control while group 2, 3 and 4 were orally treated with one mg methomyl/kg BW for 10, 20 and 30 days, respectively.

Rubinstein-Taybi syndrome (RTS) is a well-defined syndrome characterized by facial abnormalities, broad thumbs, broad big toes, and growth and mental retardation as the main clinical features. RTS was shown to be associated with disruption of the CREB-binding protein gene CBP (CREBBP), either by gross chromosomal rearrangements or by point mutations. Translocations and inversions involving chromosome band 16p13.
