The scanning electron microscopy (SEM) technique combined with an EDXRS system has been applied to the study of ancient glasses, to determine whether repairs have been carried out or substitutions made of damaged parts [1]. In this work, we exploit image processing technique in order to enhance the SEM digital image, to improve its readability and, therefore, the identification of significant d...

OBJECTIVE To evaluate the foetal outcome in Meconium Stained Amniotic Fluid (MSAF). MATERIAL AND METHODS This prospective observational study was carried out in the Department of Obstetrics and Gynaecology, North Eastern Indira Gandhi Regional Institute of Health And Medical Sciences, Shillong, India, over a period of eighteen months, from January 2010 to June 2011.

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016215025 DESCRIPTION An 11-year-old girl presented with mild right upper lid swelling for 2 weeks, associated with mild inflammation. She was treated with topical antibiotics as a case of chalazion by her family physician. Unfortunately, the problem failed to respond to treatment and blo...

The history and iconography of Swiss stained glass dating between the 16th and 18th centuries are well studied. However, the chemical and morphological characteristics of the glass and glass paints, particularly the nature of the raw materials, the provenance of the glass, and the technology used to produce it are less well understood. In this paper, we studied two sets of samples from stained-...

Methods are described for determining the relative mass of particles in electron microscope specimens through the measurement of photographic densities in recorded images. These methods were applied to a quantitative study of the amounts of electron stains that could be associated with the particles of tomato bushy stunt virus (BSV) and tobacco mosaic virus (TMV). In the pH range above 2 where ...

Quantitative aspects of cytology and histology should be considered in diagnostic standardisation processes. The present paper summarises the cytological differences detected in 75 thyroid lesions using a computerized textural analysis. Cells stained with progressive hematoxylin and taken from paraffin blocks were overlaid with the extracted texture. This technique was based on the lineal detec...

Recently investigators have reported knob-like particles on mitochondrial membranes isolated from different organisms (1, 2, 4, 5). This report presents observations on the structure of plant mitochondria, negatively stained with phospho-tungstic acid, which show knob-like projections on the membranes. MATERIALS AND METHODS Castor beans (Ricinus communis) were soaked for 24 hours in distilled w...

Microquantity differential display analysis of gene expression profiles between benign (PNT2) and malignant (PC3M) human prostate cell lines identified the gene encoding ribosomal protein L19 (RPL19) to be overexpressed in the malignant cells. Northern blot hybridization analysis done on a wide range of human cell lines and tissues confirmed the level of RPL19 mRNA to be 5-fold higher in malign...

Occurrence of glutathione S-transferase placental form (GST-P)-positive hepatocytes was examined, using 15 Wistar rats of both sexes each orally administered 2,3,7,8-tetrabromo-dibenzo-p-dioxin (TBDD) by gavage at a single dose of 0, 10, 30, 100 or 300 microg/kg body weight. Liver tissues were stained with anti-GST-P antibody. Two different types of GST-P-positive hepatocytes were found in the ...
