Obsessive-compulsive disorders (OCDs) and substance use disorders (SUDs) are listed in two separate sections in psychiatric classifications. However, they share many clinical, physiological, and epidemiological aspects. SUDs affect more than one-quarter of individuals who seek treatment for OCD, and the lifetime comorbidity rate between OCD and SUDs reaches 27%. Furthermore, the co-occurrence o...

Aim: The aim of the present study was to evaluate final color CAD-CAM produced thin lithium disilicate ceramics cemented with A2, opaque, and bleach resin cements on darker backgrounds. Materials Method: Nine different experimental groups (n=10) were generated according colors backgrounds (ND3:A3, ND4:A3.5, ND8:A4) (A2, bleach). Target specimen prepared by cementing ceramic layer onto ND2 (A2) ...

Cone dark adaptation (da) (measured with an electroretinogram [ERG] method) is found to be severely retarded when the subject (human and macaque monkey) is under halothane anesthesia. The degree of retardation depends both on the halothane level and on the bleach history. The effect of bleach history shows a great similarity with psychophysical findings concerning foveal da. Interpretation of h...

Hypochlorous acid (HOCl), the active ingredient in household bleach, is an effective antimicrobial produced by the mammalian host defense to kill invading microorganisms. Despite the widespread use of HOCl, surprisingly little is known about its mode of action. In this study, we demonstrate that low molar ratios of HOCl to protein cause oxidative protein unfolding in vitro and target thermolabi...

RNA-based applications requiring high-quality, non-degraded RNA are a foundational element of many research studies. As such, it is paramount that the integrity of experimental RNA is validated prior to cDNA synthesis or other downstream applications. In the absence of expensive equipment such as microfluidic electrophoretic devices, and as an alternative to the costly and time-consuming standa...

the aim of this study was to determine the effects of 40% hydrogen peroxide and 15% carbamide peroxide on microhardness and color change of a silorane-based composite resin in comparison with two methacrylate-based composites.fifty-four disc-shaped specimens (a3 shade) were fabricated of filtek p90 (p90), filtek z350xt enamel (z350) and filtek z250 (z250) (3mespe) (n=18). the samples of each co...

background: sodium hypochlorite is found in bleaching agents used to cleaning dishes and bleach laundry. the ingestion of sodium hypochlorite causes acute corrosive esophagitis and gastritis. in establishing the diagnosis and therapeutic approach of acute corrosive poisonings, the upper endoscopy has great importance. the aim of this study was to determine predictive factors of gastrointestinal...

Habitat structural complexity is a key factor shaping marine communities. However, accurate methods for quantifying structural complexity underwater are currently lacking. Loss of structural complexity is linked to ecosystem declines in biodiversity and resilience. We developed new methods using underwater stereo-imagery spanning 4 years (2010-2013) to reconstruct 3D models of coral reef areas ...
