The mottler of white (mw) locus has been determined to interact with alleles of the white (w) eye color locus which are a subset of the transposable element insertion mutants. The transposable elements belong to six different types, including copia, and are located at several sites within the w gene. Three X-ray-induced revertants of white-apricot (wa) no longer respond to mw, indicating that t...

This study evaluated the bond strength (push-out method) and Knoop hardness of Z250 composite resin, photoactivated with XL 2500 curing unit, using different protocols: continuous mode (700 mW/cm(2) for 20s) (CO); soft-start (50 mW/cm(2) for 5 s, followed by 700 mW/cm(2) for 15 s) (SS1); soft-start (100 mW/cm(2) for 5 s, followed by 700 mW/cm(2) for 15 s) (SS2); soft-start (150 mW/cm(2) for 5 s...

Grb2-associated binder (Gab) docking proteins regulate signals downstream of a variety of growth factors and receptor tyrosine kinases. Neuregulin-1 (NRG-1), a member of epidermal growth factor family, plays a critical role for cardiomyocyte proliferation and prevention of heart failure via ErbB receptors. We previously reported that Gab1 and Gab2 in the myocardium are essential for maintenance...

Morphological characterization has been used to explain the previously observed strong correlation between charge carrier mobility measured with thin-film transistors and the number-average molecular weight (MW) of the conjugated polymer regioregular poly(3-hexylthiophene). Atomic force microscopy and X-ray diffraction show that the low-mobility, low-MW films have a highly ordered structure com...

We have used transmission ellipsometry to measure the glass transition temperature, T(g), of freely-standing films of atactic and syndiotactic poly(methyl methacrylate) (PMMA). We have prepared films with different molecular weights, MW, (159 x 10(3) < M (w) < 1.3 x 10(6)) and film thicknesses, h, ( 30 nm < h < 200 nm). For the high-MW ( M (w) > 509 x 10(3)) atactic PMMA films, we find that T(g...

Preparations of human plasma rich in antihemophilic factor (AHF, factor VIII) correct the coagulative defect of classic hemophilic plasma, form precipitates with specific heterologous antiserum, and support aggregation of platelets by ristacetin and retention of platelets by columns of glass beads. Whether these various properties can all be attributed to a single molecular species is disputed....

PURPOSE New corneal cross-linking (CXL) devices are capable of using higher UV-A light irradiances than used in original CXL protocols. The Bunsen-Roscoe law states that a photochemical reaction should stay constant if the delivered total energy is kept constant; however, little clinical data are available to support this hypothesis. METHODS We investigated the biomechanical properties of fou...

This study was conducted to determine fertilization rate and embryo development using the Beltsville Sperm Sexing Technology with two different laser power outputs, 25 and 125 milliwatts (mW). Freshly ejaculated boar semen was diluted; one aliquot was not stained or sorted (nonsort) and a second aliquot was stained with Hoechst 33342 and sorted as a complete population, not separated into X and...

Wheelchair mobility is a prerequisite to being able to carry out important activities and to participate in social life. Level of satisfaction with the wheelchair and overall quality of life were found to be positively associated. The aim of this study was to determine the level of satisfaction of French manual wheelchair (MW) users and caregivers with MW characteristics. A total of 132 users a...
