BACKGROUND Histoplasmosis (HP) is diagnosed by visualizing intracellular microorganisms in biopsy and/or culture. Periodic-acid Schiff (PAS) and Gomori methenamine silver (GMS) staining methods are routinely used for identification. The acid-fast property of Histoplasma was identified decades ago, but acid-fast staining has not been practiced in current surgical pathology. Awareness of the acid...

Drawing upon reflectance behavior of woodland colors involving dark brown in the UV-Vis-IR bands, two colored pigments were used to print cotton/polyester Co/PET goods. Inorganic nanoparticles of TiO2, ZnO and AL2O3 were also loaded onto the printing formulation. The reflectance profile of treated samples was studied using Jasco V-670 reflectance spectrophotometer. SEM analysis of printed fabri...

Dyeing properties of different fabric species were investigated using leaf extract Juglans regia L. For this purpose, the cotton and wool fabrics dyed brown napthaquinon colorant extracted from walnut leaves by pre-mordanting, meta-mordanting post-mordanting methods in presence copper sulfate (CuSO4.5H2O), ferrous (FeSO4.7H2O) alum (AIK(SO4)2.12H2O) at medium pH. Color codes determined with Pan...

This work aims to conduct an eco-friendly textile finishing process by applying agricultural by-products as a dye for the of polyamide fabrics. A natural was obtained from pomegranate peel extract. Polyamide fabrics were dyed at different conditions, and four mordanting agents tested. The finished analyzed in terms CIE L, a, b color yield (K/S) values, well washing fastness, rubbing light fastn...

Background There are many critical steps for the clinical efficacy of antigen-specific T cell-based immunotherapies among which traffic to and access to tumor beds of effector T cells, are the most limiting [1]. Preclinical research most often uses ectopic mouse tumor models for the readout fastness and easiness provided by such models. However, those models may not be the optimal way to addres...

A variety of analytical techniques was employed to study the composition of the chlamydospore of Candida albicans. The outer, thin, electron-transparent layer was found to be composed of glucan, together with a small amount of chitin. The inner, thick, electron-dense layer is proteinaceous. The central structure is composed largely of ribonucleic acid and lipid globules. In addition to being ac...

The dye used on the silk textiles in an as yet undated relic shrine in a church in Antwerp was analysed by reflectance UV-Vis spectrometry. The natural dyestuff carthamin from safflower (Carthamus tinctorius) was detected; because of its very poor light fastness this does not allow the shrine to be exhibited. Neither does it allow dating of the silk, since safflower has been used over a period ...

Cotton hanks were dyed with three different sulphur dyes using non-sulphide reducing agents such as glucose, fructose, invert sugar and molasses. The alkalies employed for reduction were sodium carbonate and sodium hydroxide. Invert sugar as a reducing agent and sodium carbonate as alkali proved to be better as this combination gave results comparable to those obtained with the conventional sod...
