  Background: In some populations, obesity and body weight related disorders show a correlation with polymorphisms in three subtypes of beta-adrenoceptor (β1, β2, and β3) [ADRB1, ADRB2 and ADRB3] genes. We scanned for the polymorphism of Arg389Gly (...
Abstract   Medulloblastoma is an aggressive primary brain tumor that arises in the cerebellum of children and young adults. The Sonic Hedgehog (Shh) signaling pathway that plays important roles in the pathology of this aggressive disease is a...
Abstract   Reactive oxygen species (ROS) are cytotoxic agents that lead to significant oxidative damage. Bisphenol A (BPA) is a contaminant with increasing exposure to it and exerts both toxic and estrogenic effects on mammalian cells. Due to...
Abstract. The species IUCN conservation status of smooth-coated otter (Lutrogale perspicillata) is considered ‘Vulnerable’, due to an inferred future population decline caused by habitat loss and sustained exploitation. The status of the Arabian...
Abstract:  Purpose: To assess whether bisphenol A contamination occurred in seven brands of bottled drinking water in Riyadh, Saudi Arabia.Methods: Liquid-liquid extraction (using dichloromethane) was used to analytically extract bisphenol A from...
Abstract:    The aim of this study was to evaluate the toxic effects of Cassia senna fruits in Lohman broiler chicks. Chicks fed with diet containing 2 and 5% C. senna fruit for 4 weeks, thereafter the chicks in the two groups were fed with control...

  Abstract    Breast cancer causes death due to distant metastases in which tumor cells produce matrix metalloproteinase (MMP) enzymes which facilitate invasion. Oleuropein, the main olive oil polyphenol, has anti-proliferative effects. This study...
Abstract   Breast cancer is a major worldwide public health concern for women. It still remains the second most prevalent form of cancer which is terminal despite the advances made in the therapeutic approach. Polyphenols in olive oil and leaves...
Abstract   Phytotherapy has a promising future in the management of diabetes, considered to be less toxic and free from side effects as compared to the use of synthetic drugs. The aim of the present study was to assess the antidiabetic possible of...
 Abstract   Breast cancer constitutes a major health problem for women worldwide. However, its incidence varies between populations and geographical locations. These variations could be diet-related, since there are several carcinogenic compounds in...
Abstract   The study was designed to assess the antioxidative potential of three dietary antioxidants, vitamin C, Rosemary (Rosmarinus officinalis) leaf extract (10% carnosic acid) and Amla (Embilica officinalis) fruit extract (aqueous) on cadmium-...
Abstract    The aim of this study is to investigate the prevalence of some diseases in domestic livestock in two protected areas in Saudi Arabia where gazelles have been reintroduced. King Khalid Wildlife Research Centre (KKWRC) was established in...
 Abstract:   Breast cancer is a major health problem worldwide. Olive oil induces apoptosis in some cancer cells due to its phenolic compounds e.g. oleuropein. Although oleuropein has an anticancer activity, the underlying action mechanism remains...
Abstract   Toxoplasmosis is a widely prevalent zoonotic disease. The prevalence of Toxoplasma gondii (T.gondii)infection in chicken is a good indicator of soil contamination with T.gondiioocysts. Since chicken meat is widely consumed in many...
 Abstract: Toxoplasma 3 main clonal lineages are designated as type I, II, and III; however, atypical and mixed genotypes were also reported. This study was conducted for detection of Toxoplasma gondii genotypes in rats (Rattus rattus) in Ri­yadh...
Abstract.   Background: Leishmania is a unicellular protozoan parasite causing a wide range of human diseases ranging from localized self-healing cutaneous lesions to fatal visceral infections. Objective: The aim of the present study is to assess...
Abstract   One of the common causes of iron overload is excessive iron intake in cases of iron-poor anemia, where iron saccharate complex (ISC) is routinely used to optimize erythropoiesis. However, non-standardized ISC administration could entail...
Abstract   Introduction: Toxoplasma gondii (T. gondii) is an intracellular protozoan that can infect all mammals, who serve as intermediate host. It causes congenital, neurological, eyes complications and mild or asymptomatic infections in humans....
