A retrospective study of 34 sequential gamete intra-Fallopian transfer (GIFT) procedures suggested a significant effect on pregnancy rates associated with the different laparoscopic light sources, with a pregnancy rate of 50% in 22 cycles using a halogen light source and 9% in 12 cycles using a xenon light source. Other explanatory variables were explored, but none was to have a significant eff...

The present study measured the concentrations of toxic metals (Cd, Pb) and other elements (Ca, K, Mg, Na, P, Mn, Fe, Zn, Cu, Co, Cr, Ni) in tea leaves and their infusions. The total metal contents were determined by atomic absorption spectrometry. Phosphorus concentration was determined using an ultraviolet-visible spectrophotometer. Assessment of the mineral composition enabled determination o...

Despite the widespread prevalence of daily sunscreen usage, solar-induced skin damage continues to occur. We have previously reported that solar visible light and near-infrared, in addition ultraviolet radiation, perform as aging factors induce deleterious effects such photoaging, vasodilation, muscle thinning, ptosis, photoimmunosupression photocarcinogenesis. this, most commonly used sunscree...

Silver–tantalum (Ag–Ta) thin films were fabricated by magnetron co-sputtering on silicon (Si) wafer (100) and glass slide substrates at room temperature. The Ag–Ta prepared various deposition times of 5, 10, 20 30 s the physical, structural optical properties investigated. It was determined that thicknesses 7, 9, 17 33 nm, respectively. results revealed an increase in film thickness leads to a ...

nanocrystalline titanium (iv) oxide paste has been deposited on fluorine doped tin oxide glass substrate by the blade method. the deposited film was subjected to thermal treatment to obtain an electrode foe a photo-electrochemical cell. the electrode was sensitized with prophyrin dye which was a local dye extracted from carica papaya leaves. avaspec 2.1 spectrophotometer was used to obtain the ...

In this work, SnO2 and Ti-doped thin films were produced by successive ionic absorption reaction methods on platin interdigital contacts. The not annealed. Structural properties of amorphous investigated using X-ray Diffraction (XRD), morphological Scanning Electron Microscopy (SEM), optical electrical Ultraviolet-visible Spectrophotometer (UV-VIS) Keithley 2400 instruments. From the XRD result...

Bee bread is a food product obtained by fermenting bee pollen with honey and storing it in honeycomb cells. In this fermentation, phenolic compounds remain unaffected unchanged. contains approximately; there are 35% sugar, 24-35% carbohydrate, 20-22% protein, 3.5% lactic acid, 2.43% mineral, 1.6% lipid fat. Within the scope of study, biocompatible iron nanoparticles were synthesized (BB@FeNPs) ...

BACKGROUND Skin pigmentation is a key factor for ultraviolet radiation exposure-related cancers and can make a significant contribution to the patterns of other diseases. For surveys, and to appropriately target cancer control activities, valid and reliable measures of skin color are required. METHODS Validity and reliability of the Munsell Soil Color Charts were investigated for skin color a...
