INTRODUCTION Minor physical anomalies (MPA) are dysmorphic features that reflect deviations in early development, are morphological variants that appear during the first trimester of pregnancy and could be used as a marker of disease risk in susceptible people. The literature agrees that the number of MPA is higher in patients with schizophrenia compared with their relatives and healthy subject...

one of the important issues in the arid and semi-arid regions is the water deficit and soil salinity. therefore, selecting tolerant species to salinity and drought especially in seed germination and emergence stage is important. in the present study the effects of drought and salt stress on seed germination of vetch (vicia villosa l.) which is palatable forage was investigated. the germination ...

OBJECTIVE This study evaluated the influence of different surface treatments on the resin bond strength/light-cured characterizing materials (LCCMs), using the intrinsic characterization technique. The intrinsic technique is characterized by the use of LCCMs between the increments of resin composite (resin/thin film of LCCM/external layer of resin covering the LCCM). MATERIALS AND METHODS Usi...

OBJECTIVE It has been reported that the progestin medroxyprogesterone acetate (MPA), but not norethindrone acetate (NETA), inhibits the beneficial vascular effects of post-menopausal estrogen therapy, but their effects on the myocardium are unclear. The goal of this study is to compare the effects of these two progestins on post-ischemic myocardial damage. METHODS Ovariectomized monkeys were ...

STATEMENT OF THE PROBLEM Porcelain may fracture or chip if exposed to any traumas and can be repaired by using a resin composite. PURPOSE This study was aimed to evaluate the influences of Er:YAG laser on shear bond strength (SBS) of resin composite to feldspathic porcelain. MATERIALS AND METHOD Seventy-two porcelain blocks were divided into six groups (n=12): G1: no treatment (control grou...

The effect of compressional force on the crystallinity of low crystallinity cellulose (LCPC), microcrystalline celluloses (Avicel PH-101, PH-102 and PH-302 grades) and powdered cellulose (Solka Floc BW-100) has been investigated using an X-ray diffraction method. Microcrystalline and powdered celluloses showed an increase of about 10% in their crystallinities, compared to the values for the cor...
