Soil does not always bene®t from disturbance by earthworms. We investigated whether (under a temperate climate and in maize growing in rows running down-hill) earthworm casts could contribute to soil erosion and losses of nutrients in runo€ water. Observations of casts were made in compacted (wheel-tracks) and non-compacted (untracked) inter-rows, for a 2-month period in spring. Estimates of s...

BACKGROUND The accuracy of implant casts generated with various impression techniques was mainly investigated in vitro resulting in limited clinical data. PURPOSE (1) To compare the three-dimensional (3-D) accuracy of splinted and non-splinted impression techniques to the control casts (verification jigs) that had been used for actual patient treatment; and (2) to determine the maximum level ...

Treatment with interferon alfa combined with ribavirin is successful in approximately 40% to 45% of patients with chronic hepatitis C viral infection (HCV). However, response rates are disappointing in patients who are difficult to treat, such as those infected with HCV genotype 1, high viral load, or advanced liver fibrosis. In addition, low tolerability and significant side effects of therapy...

This paper presents a n ew method for detection and adjustment color cast. Using the neural network to detect color cast and classify images into three subsets: no cast, real cast, and intrinsic cast (image presenting a cast due to a predominant color that must be preserved). We have a database of 700 images which are downloaded from internet or acquired using various digital still cameras. We ...

Scanning electron microscopy (SEM) of vascular corrosion casts (microvascular corrosion casting/SEM method) is a standard method, which allows three-dimensional visualization with good resolution of the normal and abnormal microvessels, including the capillaries of various organs and tissues. SEM of vascular corrosion casts can obtain qualitative as well as quantitative informations important t...

An investigation of enzyme content of diseased human kidneys was carried out. A broad spectrum of enzymes was studied histochemically in these kidneys. A surprising finding of the presence of various lysosomal, microsomal, and nuclease enzymes was demonstrated in epithelial casts in the kidneys. In contrast, mitochondrial enzymes were not present in the epithelial casts. This study has demonstr...

⦁ Background: Despite the continuous interest in search for therapeutic agents, little attention has been given to medicinal relevance of earthworm casts, with even less over-seasoned worm-casts. Therefore, this study determined phytochemical, antimicrobial, and cytotoxic properties worm-casts Hyperiodrilus africanus (Eudrilidae). Methods: The casts were extracted n-hexane, ethanol, water crude...

OBJECTIVE To compare the use of the 5-year-olds' index on both dental study casts and intraoral photographs when measuring primary surgical outcome for children born with unilateral cleft lip and palate (UCLP). DESIGN A cross-sectional study. SETTING Models and photographs collected from cleft units across the UK as part of the CCUK (Cleft Care UK) study were scored by two clinicians at the...
