The chemical speciation of heavy metals (arsenic, chromium, copper, lead, zinc and tin) in the sediments of former tin mining catchment Bestari Jaya, Peninsular Malaysia was determined by using the latest version of the Community Bureau of Reference, usually called the BCR 3-step sequential extraction procedure. Furthermore, a fourth step was introduced for digestion and analysis of the residue...

The present study aimed to investigate the in vitro starch digestion of cooked rice grain with added vegetable oils. Polished (400 g) was 500 mL ultrapure water only or one six types oils (cocoa butter [CB], coconut oil, corn oil [CO], olive [OO], palm and rapeseed [RO]), then frozen stored. reheated using a microwave used for texture analysis, gastro-small intestinal digestion, microstructure ...

We describe a simple and convenient method for processing small amounts of tissue samples for trace-metal measurements by atomic absorption spectrometry, by use of a modified Parr microwave digestion bomb. Digestion proceeds rapidly (less than or equal to 90 s) in a sealed Teflon-lined vessel that eliminates contamination or loss from volatilization. Small quantities of tissue (5-100 mg dry wei...

One of the major technical advances in the field of histopathology during the last decade is the development of immuno-histochemical (ll{C) techniques. Growing demand of antibodies that can be used for IHC on routine formalin fixed paraffin embedded tissues has stimulated efforts to develop antibodies that can recognize formalin-resistant epitopes. Alternatively, it is desirable to devise strat...

Two pretreatment methods, microwave irradiation and steam explosion, were investigated in this work. The aim of the study was to investigate whether these methods would improve the biodegradability of wheat straw as a lignocellulosic feedstock. Microwave pretreatment was carried out on milled straw with an irradiation time of 15 minutes, at a temperature of either 200 or 300 °C in the oven. The...
