The various theories of the nature of the act of staining of animal cells, tissues and products, which have been put forward by different writers fall into three groups: (i) that the process of staining is a chemical reaction between the dye on the one hand, and the cell or tissue elements on the other; (2) that in staining the dye is adsorbed by the tissue elements stained; and (3) that the dy...

Malassezia spp. are lipid-dependent yeasts that have been related to skin mycobiota and dermatological systemic diseases. Study of lipid droplets (LDs) is relevant elucidate the unknown role these organelles in gain a broader overview metabolism Malassezia. Here, we standardized two protocols for analysis LDs M. pachydermatis globosa. The first describes co-staining confocal laser-scanning fluo...

Monochromatic unique green (UG) is more variable across the population than any other unique hue. Some researchers have reported that this broad distribution of UG settings is bimodal and that the distribution results from the superposition of two or more subpopulations. We have investigated this claim using a Wright colorimeter to measure the unique green wavelength of 58 participants and we h...

OBJECTIVE The purpose of this study was to find whether Cardiac Magnetic Resonance (CMR) could assess the myocardial interstitium in patients suffering from systemic amyloidosis with normal left ventricular ejection fraction. METHODS Twenty Six patients in whom systemic amyloidosis was confirmed by kidney biopsy were investigated. Five patients with normal left ventricular ejection fraction w...

Following Hartman, who first suggested the use of Sudan black B, in place of red Sudans, as a bacterial fat stain (Hartman, 1940), Burdon, Stokes, and Kimbrough (1942a) confirmed the greater value of this dye and modified the procedure for demonstrating intracellular fatty material in bacteria by preparing, from suspensions of the organisms in alcoholic Sudan black B solution, dried films count...

BACKGROUND Extrinsic staining of teeth may result from the deposition of a variety of pigments into or onto the tooth surface, which originate mainly from diet or from tobacco use. More recently, clinical studies have demonstrated the efficacy of some chewing gums in removing extrinsic tooth staining. The aim of this study was to assess the effectiveness of two nicotine medicated chewing gums (...

background: in the field of cellular therapy, the impact of confluence degree to harvest or differentiate bmmscs and the effect of cell-to-cell contact remains controversial. therefore, the effect of confluence on bmmscs properties was studied and confluence-associated osteogenic differentiation efficiency was identified. materials and methods: the impact of confluences at 20, 50, 70, 80 and 10...
