Seeds of pearl millet (Pennisetum glaucum (L) R. Br.) from six provenances of Tunisia were subjected to germination and shoot and root length tests on filter paper treated with polyethylene glycol 6000 (PEG 6000) solutions made up to provide osmotic potentials of 0, -1 and -2 MPa. Mean germination percent for all provenances decreased about 73% in -2 MPa compared to control (0 MPa) treatment. O...

background and aims. er:yag laser irradiation has been claimed to improve the adhesive properties of dentin; therefore, it has been proposed as an alternative to acid etching. the aim of this in vitro study was to investigate the shear bond strength of an etch-and-rinse adhesive system to dentin surfaces following er:yag laser and/or phosphoric acid etching. materials and methods. the roots of ...

although some vitamins have been shown to prevent glucocorticoids induced osteoporosis in short time, the magnitude of this effect remains to be clarified. the aim of this study was to evaluate protective effect of vitamin d3 on methylprednisolone acetate (mpa) induced osteoporosis in rats. twenty-four male sprague dawley rats were randomly divided into four groups: group a (n = 6), was a base ...

BACKGROUND AND PURPOSE Histotripsy is a pulsed focused ultrasound technology in which initiation and control of acoustic cavitation allow for precise mechanical fractionation of tissues. The present study examines the feasibility of using histotripsy for erosion of urinary calculi. MATERIALS AND METHODS Histotripsy treatment was delivered from a 750-kHz transducer in the form of 5-cycle acous...

Understanding of cell cycle regulation in hormonally responsive cells lags behind studies in other systems because few models have been available to identify the role of steroid hormones and their receptors in this process. This study investigates progesterone-dependent effects on the progression of normal uterine stromal cells through early G1 phase of the cell cycle. Quiescent rat uterine str...
