BACKGROUND Microwave is the most reliable sample digestion method. However, it requires expensive microwave digester automation and has relatively low productivity. In this study, three non-automated digestion methods, i.e. wet acid digestion using nitric acid (HNO3) and hydrogen peroxide (H2O2), wet acid digestion using HNO3, and dry washing, are compared in order to determine the best approac...

Failure to obtain sufficient material from marrow aspiration (dry tap) posed a diagnostic problem in two patients with pancytopenia. By using collagenase digestion of the trephine biopsy specimen, a precise diagnosis was reached. This technique is very useful because it permits flow cytometric and immunocytochemical analyses of cell suspensions obtained after collagenase digestion of the trephi...

Anaerobic digestion of dairy cow manure (CM), the organic fraction of municipal solid waste (OFMSW), and cotton gin waste (CGW) was investigated with a two-phase pilot-scale anaerobic digestion (AD) system. The OFMSW and CM were digested as single wastes and as combined wastes. The single waste digestion of CM resulted in 62m3 methane/ton of CM on dry weight basis. The single waste digestion of...

The production and application of compost potentially contaminate the environment with heavy metals. The heavy metal contents of composts must be exactly determined. Therefore, this study aims to understand the heavy metal contents in composts, using different digestion methods and to recommend the most appropriate digestion method making this measurement. Nine composts from different sources, ...

A digestion trial using cannulated lactating cows was conducted to evaluate the influence of barley grain processing on characteristics of ruminal fermentation and the site and extent of digestion. The experiment consisted in 4 periods and lasted 84 days. The total mixed rations contained 39.86% of grains and 42.90% of alfalfa hay and the rest of ration was composed mainly by cane molasses, fat...

The hot water extract of dry kinkéliba leaves (DKL) is a traditionally widely delighted and consumed beverage in West Africa, especially during the fasting periods. It is believed to possess various health benefit effects such as diuretic, purgative, digestive, anti-viral and anti-malarial properties. However, the preparation of this beverage has not been optimized so far, which may underestima...

In vitro techniques were evaluated to determine the nutritive value of a selection of tanniniferous tree and shrub legumes (Calliandra calothyrsus, Leucaena leucocephala L. diversifolia and L. pallida) compared with lucerne (Medicago sativa). Polyethylene glycol (PEG) was also added to some in vitro fermentations (10 mg PEG/50 mg plant substrate) to assess the effects of tannins on digestion of...

Accepted for publication 1 1 February 1994 Abstract Objectives-To analyse the collagen composition of normal adult human supraspinatus tendon and to compare with: (1) a flexor tendon (the common biceps tendon) which is rarely involved in any degenerative pathology; (2) degenerate tendons from patients with chronic rotator cuff tendinitis. Methods-Total collagen content, collagen solubility and ...
