BACKGROUND AND AIMS The sterilization of the entire root canal system represents the main goal of every endodontist, given the fact that the control of the microbial flora is the key point of every root canal treatment. The diversity of microorganisms found inside the root canal and also the resistance of some bacterial species to intracanal medications led to a continuous development of new en...

It has been over 10 years since the first mention in a medical journal about cocoa and chocolate as potential sources of antioxidants for health. During this time, cocoa has been found to improve antioxidant status, reduce inflammation and correlate with reduced heart disease risk; with these results, and its popularity, it has received wide coverage in the press. However, after 10 years of res...

this experiment was conducted to evaluate the effects of different levels of dried aerial parts powderand extract of pennyroyal­ (mentha pulegium) medicinal plant on performance, egg traits, blood biochemical and immunity parameters of laying hens. two-hundred-fifty-two hi-line (w36 strain) laying hens from 46 until 58 weeks of age were used in a completely randomized design in 7 treatments and...

Black beans (Phaseolus vulgaris L.) are a rich source of flavonoids and saponins with proven health benefits. Spray dried black bean extract powders were used in different formulations for the production of nutraceutical capsules with reduced batch-to-batch weight variability. Factorial designs were used to find an adequate maltodextrin-extract ratio for the spray-drying process to produce blac...

this experiment was conducted to evaluate the effects of different levels of dried aerial parts powder and extract of tanacetum balasmita (tb) medicinal plant on performance, carcass traits and blood parameters of broilers. two hundred eighty ross-308 broilers from 10 to 42 days of age were used in a completely randomized design in 5 treatments and 4 replicates (14 birds per replicate). the tre...

Aim of the study is to investigate the Nephroprotective activity of ethanolic extract taken from Melia azadirachta leaves, against APAP (Acetaminophen) induced nephrotoxicity. The phytochemical screening was carried out on the leaf extracts of Melia azadirachta, revealed the presence of active ingredients such as Phytol, Squalene, Oleic Acid, 2-Piperidinone, N-[4-bromo-n-butyl]. Leaves of Melia...

A response surface approach was used to investigate the effects of temperature, concentration, and time on the antioxidant properties (total flavonoid (TF), total phenol (TP), peroxide scavenging activity (PS), iron chelating activity (IC), DPPH radical-scavenging ability (DPPH), ABTS assay (ABTS)) of aqueous extract of tea-ginger (2:1) powder. Color indices, pH, and redox potential of the tea-...

introduction antibiotic feed additives have long been used as growth promoters in poultry nutrition. however, concern has been expressed about the potential development of antibiotic resistant bacteria (25). consequently, the animal feed industry, exposed to increasing consumer pressure to reduce the use of antibiotic growth promoters in poultry diets, has to find alternative feed additives. ma...

BACKGROUND Many oxidative stress related diseases are as a result of accumulation of free radicals in the body. A lot of researches are going on worldwide directed towards finding natural antioxidants of plants origins. The aims of this study were to evaluate in vitro antioxidant activities and to screen for phytochemical constituents of Helichrysum longifolium DC. [Family Asteraceae] aqueous c...
