BACKGROUND Studies have shown that mini-αA can protect retinal pigment epithelium (RPE) cells from apoptosis. However, no in vivo study concerning the anti-apoptotic function of mini-αA has been conducted yet. METHODS MTT assay, HE staining and TUNEL assay were used to assess levels of cells, and an animal model was established to examine the protective effects of mini-αA against NaIO3-induce...

OBJECTIVES To evaluate the accuracy of using routine 2-dimensional (2D) radiographs (panoramic and periapical) when evaluating the position of orthodontic temporary anchorage devices (mini-implants) in the maxilla, and to compare the results to 3-dimensional cone-beam computed tomography (CBCT). METHODS This cross-sectional study was conducted at King Abdulaziz University, Faculty of Dentistr...

Aminoacyl tRNA synthetases--enzymes that catalyze the first step of protein synthesis--in mammalian cells are now known to have expanded functions, including activities in signal transduction pathways, such as those for angiogenesis and inflammation. The native synthetases themselves are procytokines, having no signal transduction activities. After alternative splicing or natural proteolysis, s...

Conflict of interest: none. ABSTRACT Objective: To evaluate the diagnostic sensitivity, specificity, and agreement of the Dementia Rating Scale with clinical diagnosis of cognitive impairment and to compare its psychometric measures with those from Mini Mental State Examination. Methods: Eighty-six elders from a long-term care institution were invited to participate in a study, and fifty-eight ...
