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 aimed to investigate the effect of oleuropein on the metastatic and anti-metastatic gene expression in
the MDA human breast cancer cell line. We evaluated the MMPs and TIMPs gene expression by semi-quantitative
reverse transcriptase polymerase chain reaction (RT-PCR) in treated and untreated cells. This study demonstrated

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 drinking water bottles and a gas chromatograph-mass spectrometer was employed for its detection
using a splitless capillary column and helium as the carrier gas.
Results: The concentration of bisphenol A (BPA) was high in all the bottled water brands tested. The

The aim of the present study was to determine the prevalence of Toxoplasma gondii antibodies in
serum samples from two groups of women in Sudan and to use molecular techniques for detection of
the organism’s DNA using B1 gene. The first group (study group) composed of 94 individuals and they
aborted during the study, while the second group (control group) also composed of 94 individuals who
gave birth to healthy children without complications. Serological screening using enzyme linked

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 diet for 2 weeks. Depression in body weight, weight gain, inefficiency of
feed utilization and anaemia was observed in chicks fed with 2 and 5% C. senna compared with the
control diet. There were significant increase in the serum values of sorbitol dehydrogenase, lactate

Eimeria dorcadis Mantovani, 1966 is redescribed from dorcas gazelle (Gazella dorcas (L.)) from Saudi Arabia.
Oocysts were detected in 7 out of 22 faecal samples (32%) using floatation method. The sporulated oocysts are cylindrical, slightly flattened at the micropylar pole, measure in average 32 × 19 μm (27–36 × 16–24 μm), length/width ratio being 1.7 (1.5–2.1). Oocystwall is 1.2 μm thick, smooth, double-layered; outer layer is slightly thicker, light blue in colour; inner layer brownish, with micropyle

The possible effect of Commiphora myrrha oleo-gum resin was studied on
rats fed different concentrations of the crude plant. The plant is used in different regions
for treatment of various ailments but the toxic effect of this plant has not been studied in
details.
Methods: Commiphora myrrha was fed to rats at 2, 5, 10, and 20% of the basic diet.
Results: Rats on 10% and 20% Commiphora food exhibited depression, soft faeces,
abdominal pain and dyspnoea prior to death. Lesions were fatty change and necrosis of
