When complying a good standard hygiene protocol in the dental office the risk of cross-infection of whatever type of microorganism, including the hepatitis-B-virus and HIV, is almost eliminated.

Choi, S.; Park, J-Kyun., 2010: Optically coated mirror-embedded microchannel to measure hydrophoretic particle ordering in three dimensions. Three-dimensional (3D) measurement of the behavior of microfluidic particles is vital for improving their operational efficiency and characterization. In particular, it is important to measure particle motions in 3D for exact characterization of h...

Lygo, B.; Crosby, J.; Lowdon, T.R.; Wainwright, P.G., 2001: Structure-selectivity studies on catalysts for the phase-transfer catalysed asymmetric alkylation of glycine imine esters. In this paper, we describe the synthesis of a series of chiral quaternary ammonium salts with core structures that are closely related to the cinchona alkaloid, cinchonine. By employing these salts as asymmetric phase-transfer agents in the benzyl...

The heart and main blood vessels sizes were determined by teleroentgenography and the status of cardio- and hemodynamics were determined by mechanocardiograhy in 56 healthy adolescents and 161 patients suffering from inactive rheumatic fever. Acce...

Objective: To assess bone mineral density (BMD) in men with steroid-treated rheumatoid arthritis (RA). Methods: Dual-energy x-ray absorptiometry (DXA) was used to measure BMD in 40 men with RA, 20 of whom were receiving low-dose corticosteroids (...

The implications of a mouldy commodity are considered to be that the mould serves as an index of insanitation and that the mould may serve as a p...

Liu, Y.; Cao, J.; Li, B.; Lu, J., 2017: Normalization and Solvability of Dynamic-Algebraic Boolean Networks. In this brief, we first study the normalization of dynamic-algebraic Boolean networks (DABNs). A new expression for the normalized DABNs is obtained. As applications of this result, the solvability and uniqueness of the solution to DABNs are then...

The aim of the present study is to compare the tympanometric and functional findings of cartilage palisade tympanoplasty with those of tympanoplasty with temporalis fascia grafting after one-stage surgery in children with tensa cholesteatoma. In c...
