The kinetics of the depletion of plasma fibrinogen were studied in seven patients who received fibrinogen-(131)I 1 hr before an intravenous injection of the coagulating enzyme (CE) derived from the venom of the pit viper, Agkistrodon rhodostoma. Disappearance of the clottable radioactivity labeled fibrinogen from the circulation conformed to an exponential decay with an average half-life of 0.8...

Since the ultrasonically activated scalpel (UAS) incorporates multiple functions, we have used it for hepatectomies. The present study discusses the noteworthy points and problems of use, and shows initial results. Intraoperative ultrasonography is an important tool for comprehending the positional relationship between the plane of division and the main blood vessels. It allows initial adjustme...

Précis: Glass composition of individual agglutinate grain is determined largely by the composition of a few soil grains, heterogeneous with respect to the bulk soil, impacted by a micrometeorite. Common perception or consensus: Lunar agglutinates form upon micrometeoritic bombardment of lunar soils and consequent preferential melting of the (otherwise homogeneous) finer fraction, scavenging unm...

Fifty-two Holstein cows with different phenotypes of κ-casein (κ-CN) and β-lactoglobulin (β-LG) were selected to provide weekly milk samples for heating at 30, 70, 75 and 80°C for 2 min. Coagulating properties of heated milk samples measured as rennet clotting time, rate of curd firming and curd firmness at cutting were determined by a Formagraph. Milk samples were analysed for fat and casein. ...

BACKGROUND Electrocoagulation is a technique involving the electrolytic addition of coagulating metal ions directly from sacrificial electrodes. These ions coagulate with turbidity agents in the water, in a similar manner to the addition of coagulating chemicals such as alum and ferric chloride, and allow the easier removal of the pollutants. Purpose of this study was to conduct experimental in...

The problem of nipple-areola complex (NAC) preservation during mastectomy is a very intriguing and stimulating issue. In fact, in order to perform an oncologically safe operation, no mammary tissue (enclosed in the main galactophoric ducts) should remain; on the other hand, without the blood supply coming from the breast gland, NAC viability is greatly impaired because the surrounding vascular ...
