This study evaluated the influence of different thermal (TC) and mechanical (MC) cycling protocols on microtensile bond strength (muTBS) to cervical dentin margins of Class II restorations using two total-etch (TE) adhesives and one self-etching (SE) primer. Class II slot cavities were prepared on the mesial surfaces of 168 bovine incisors and were divided into three groups according to the bon...

We report that the clinically used antitumor drug mitomycin C reacts with excess dithiols to give dithiol cross-links as major products. Mechanistic studies reveal that three dithiol molecules participate at different stages of the reaction: in the reductive activation of mitomyicin C, in an alkylation at C1, and in an additional reduction that activates C10 for the second-arm alkylation by the...

Prior research has yielded mixed results regarding what contributes to psychometrically sound multiple-choice (MC) items. The purpose of the present study was, therefore, twofold: (a) to compare 3-, 4-, and 5-option multiple-choice (MC) tests in terms of psychometric characteristics, and (b) to investigate the relationships between three MC tests and five personality traits. To that end, 150 st...

BACKGROUND Current American Thoracic Society and American Association for Respiratory Care guidelines for the delivery of aerosol agents such as methacholine chloride (MC) for bronchoprovocation testing require the use of pneumatic jet nebulizers that have well-defined droplet size and mass output. A recently developed disposable, breath-actuated nebulizer (AeroEclipse) may offer bronchoprovoca...

OBJECTIVE To characterize the incidence and risk factors for monochorionic diamniotic(MC-DA) twinning after assisted reproductive technologies (ART). DESIGN Retrospective population-based study. SETTING The study was conducted in China; Department of Reproductive Medicine Center at The First Affiliated Hospital of Anhui Medical University. POPULATION A cohort of 8860 clinical pregnancies ...

Merkel cells (MC) are specialized epithelial cells, having sensory and neuroendocrine functions, and present within basal layers of epidermis (disseminated as well as clustered in Pinkus’s hair disc), and outer root sheath of hair follicles of men (Moll et al, 1986, 1993, 1995; Halata, 1993). In mice, numerous MC are present in the foot pad epidermis, whereas in the epidermis of back skin MC ar...

Fungal pathologies caused by the genus Candida have increased in recent years due to involvement of immunosuppressed people and advance resistance mechanisms acquired these microorganisms. Liposomes are nanovesicles with lipid bilayers which they store compounds. ?-Bisabolol is a sesquiterpene proven biological activities, this work it was tested alone liposomes association Fluconazole vitro ev...

In this paper, we build wellposed intrusive generalised Polynomial Chaos (gPC) based reduced models for uncertain photonics. We solve the with a Monte-Carlo (MC) scheme. Care is taken to highlight under which condition model (gPC or not) wellposed. The analysis carried out thanks an analogy between construction of uncertainty quantification and kinetic equations. order enforce aforementioned we...

Molluscum contagiosum is an infectious viral disease. The necessity to do this research in primary school of Kerman is mainly based on the high occurrence of the molluscum contagiosum (MC) among children, though an increase of the incidence of MC in adults with AIDS and immune deficiencies has also been reported. Among 1181 girls and 1440 boys, 75 were infected with MC; 29 (2.45%) and 46 (3.1%)...
