The pathogenicity of four native strains of Bacillus thuringiensis against Rhipicephalus (Boophilus) microplus (Canestrine) (Acari: Ixodidae) was evaluated. A R. microplus strain that is resistant to organophosphates, pyrethroids, and amidines, was used in this study. Adult R. microplus females were bioassayed using the immersion test of Drummond against 60 B. thuringiensis strains. Four strain...

This present study investigated the effect of ultraviolet (UV) irradiation on bioactivity of micro-arc oxidized (MAO) titanium surface in vitro by cell culture medium immersion test and interactions with rat-derived mesenchymal stem cells (MSCs). UV-irradiated MAO surface exhibited no obvious changes in surface roughness, morphology, and phase composition when compared with MAO-only surface. Ho...

A concept for prediction of organic coatings, based on the alternating hydrostatic pressure (AHP) accelerated tests, has been presented. An AHP accelerated test with different pressure values has been employed to evaluate coating degradation. And a back-propagation artificial neural network (BP-ANN) has been established to predict the service property and the service lifetime of coatings. The p...

For centuries, Damask rose has been one of the most popular species of the rose family. Damask rose can be propagated using vegetative methods such as micropropagation. In this research, the use of temporary immersion system was reported for the first time for Damask rose micropropagation. For this reason, a traditional temporary immersion system was designed to facilitate its micropropagation....

In folk medicine, Polyalthia suberosa is used as abortifacient, laxative, febrifuge analgesic, filler of tooth cavities, and anti-HIV drug and for rheumatism and various skin infections. The present study was directed to evaluate the analgesic and anti-inflammatory activities of diethyl ether and n-hexane extracts of Polyalthia suberosa leaves (PSDE and PSNH). A variety of tests including forma...

it is generally believed that unaccustomed exercise causes myofibrillar damage. in recent years, cold water immersion (cwi) following heavy training sessions and matches has been common aiming at reducing soreness. however, there is no strong scientific rationality if this method really accelerates recovery after exercise. in addition, there is a question that if it is possible for this method ...

The effect of thermoacidophilic archaeon Metallosphaera cuprina (M. cuprina) on the corrosion Q235 carbon steel in its culture medium was investigated this work. In sterile medium, steels showed uniform morphologies and almost no products covered sample surface during 14 days immersion test. presence M. cuprina, some pits appeared test, exhibiting typical localized morphologies. Moreover, surfa...

BACKGROUND Effective cleaning of dentures is important to maintain a good oral hygiene for patients suffering from denture stomatitis (DS). This study aimed to evaluate the efficacy of hexetidine 0.1% in eliminating C. albicans colonizing dentures. MATERIALS AND METHODS A total of 40 denture wearers (18 men, 22 women; age range 40-80 years) with clinical evidence of DS were randomly divided i...

AIM Using scanning electron and light microscopy, this study qualitatively evaluated the erosive potential of carbonated cola beverages as well as sports and high-energy drinks on enamel surface substrate. METHODS AND MATERIALS Beverages used in this study included: Coca Cola Classic, Diet Coke, Gatorade sports drink, Red Bull high-energy drink, and tap water (control). Extracted human perman...
