OBJECTIVES Aging is an unconscious and gradual process that can lead to changes in biological systems. Induction of oxidative stress and apoptosis, hepatotoxicity and neurotoxicity are involved in the aging process. Regarding the antioxidant property of black seed oil, the aim of this study was to evaluate the anti-aging effect of Nigella sativa (N. sativa) oil on d-galactose-induced aging in m...

The progressive rise in multidrug-resistant (MDR) bacterial strains poses serious problems in the treatment of infectious diseases. While the number of newly developed antimicrobial compounds has greatly fallen, the resistance of pathogens against commonly prescribed drugs is further increasing. This rise in resistance illustrates the need for developing novel therapeutic and preventive antimic...

OBJECTIVE The aim of this study was to elucidate the mechanism(s) responsible for the vasorelaxant effect of Nigella sativa (N. sativa). METHODS The activity of different concentrations of N. sativa extract was evaluated on contractile responses of isolated aorta to KCl and phenylephrine (PE). RESULTS The extract (2-14 mg/mL) induced a concentration dependent relaxation both in endothelium-...

Nigella sativa is the miraculous plant having a lot of nutritional and medicinal benefits, and attracts large number of nutrition and pharmacological researchers. N. sativa seed composition shows that it is the blessing of nature and it contains and many bioactive compounds like thymoquinone, α-hederin, alkaloids, flavonoids, antioxidants, fatty acids many other compounds that have positive eff...

BACKGROUND Nigella sativa is an important component of several traditional herbal preparations in various countries. It finds its applications in improving overall health and boosting immunity. The current study evaluated the role of fixed and essential oil of Nigella sativa against potassium bromate induced oxidative stress with special reference to modulation of glutathione redox enzymes and ...

After the beginning of metal processing at the transition from the Neolithic to the Bronze Age, further knowledge of ore mining and smelting had spread from the Near East to central Europe. In the copper ore deposits of Schwaz, in the central part of the Alps, the oldest traces of copper mining derive from the early to middle Bronze Ages. Investigation of a middle to late Bronze Age (1410–920 c...

In this study, the copper nanoparticles were synthesized using various concentrations (5%, 6 %, 8%, and 10%) of Nigella sativa seed extracts, their antibacterial antiobesity effect was evaluated. The optimum particle size (98.23 nm) obtained at an extract concentration 8%. FTIR results confirmed functional groups responsible for ion reduction, exhibited high activity against Pseudomonas aerugin...

OBJECTIVES Nigella sativa (N. sativa) is an amazing herb which is used in traditional medicine for a wide range of illnesses including bronchial asthma, dysentery, gastrointestinal problems, as well as beneficial effect on blood lipids, lowering blood pressure, serum cholesterol, and triglycerides level. This study aimed to determine the toxic effect of N. sativa powder on the kidney function w...

The importance of Nigella sativa plant is increasing day by in many medical and nutritional fields, the demand for it foreign markets. Therefore, we chose nigella to study effect spraying with a natural growth stimulant (Ascobein) at concentrations zero, 50, 100 150 ppm on productivity seed oil, as well its activity antioxidants. results showed that concentration gave highest values vegetative ...
