During the past decade much progress has been made in the fundamental understanding of the phenomena that govern biocatalysis in non-conventional media. The factors that affect biocatalytic reactions and the activity and stability of biocatalysts in these reaction media are generally associated with the crucial role of water and the need to keep biocatalysts in their active conformation. For th...

AIMS To investigate the roles of vascular adventitial fibroblastic cells in tumour stroma, the distribution of vascular adventitial fibroblastic cells was studied in gastric carcinomas. METHODS In total, 50 surgically resected gastric carcinomas (43 intestinal type, and seven solid type) and their normal tissues were examined. Vascular adventitial fibroblastic cells are positive for CD34 but ...

This study was conducted to evaluate the impact of implementation of an automated liquid culture system on the diagnosis of tuberculous pleurisy in an HIV-uninfected patient population. We retrospectively compared the culture yield, time to positivity, and contamination rate of pleural effusion samples in the BACTEC Mycobacteria Growth Indicator Tube 960 (MGIT) and Ogawa media among patients wi...

A thermo-chemo-electro-mechanical formulation of quasi-static finite deformation of swelling incompressible porous media is derived from a mixture theory including the volume fraction concept. The model consists of an electrically charged porous solid saturated with an ionic solution. Incompressible deformation is assumed. The mixture as a whole is assumed locally electroneutral. Different cons...

When antibiotic sensitivity of microorganisms is tested by agar dilution, single antibiotics are incorporated in solid media and 'spot' inocula of test strains are applied to the antibiotic media and to a plate without antibiotic. The usual method of quality control is to include control strains of known sensitivity.1 However, control strains are usually sensitive to a number of antibiotics, an...

Ultrasonic radiative transfer in polycrystalline media: Effects of a fluid–solid interface" (1995). In previous derivations of the ultrasonic radiative transfer equation ͑URTE͒ for the modeling of multiply scattered diffuse ultrasound in polycrystalline media, the boundary conditions appropriate to experiments performed in a water bath were not used. In the present work, this fluid–solid boundary...

Aging is a degenerative process characterized by a progressive deterioration of cellular components and organelles resulting in mortality. The nematode Caenorhabditis elegans has emerged as a principal model used to study the biology of aging. Because virtually every biological subsystem undergoes functional decline with increasing age, life span is the primary endpoint of interest when conside...
