Chitosan, a cationic carbohydrate polymer manufactured from chitin in shrimp and crab wastes, coagulated suspended solids in cheese whey as effectively or more so than ten commercial synthetic polymers. Concentrations of suspended solids after settling were reduced over 90% by coagulation at pH 6.0 with a ratio of chitosan to suspended solids of 2.15% (1:46.5). The yield of coagulated solids wa...

Among biological approaches to the removal of aromatic amines and phenols from wastewater, the so-called enzyme-catalyzed polymerization and precipitation (ECPP) process relies on the use of oxidoreductases acting via radical mechanisms and characterized by a rather relaxed substrate specificity, such as laccase, tyrosinase and peroxidases. The main technical constraints of ECPP processes are d...

The inhibitory effect of animal antiproteases such as those of blood serum and egg white is well known. Antiproteases, however, of protein nature similar to these have not been found in plants. The study of antiproteases is important in explaining certain biological phenomena. In the present paper we wish to report on a plant antiprotease which exerts a powerful inhibition on the milk-coagulati...

CONTEXT Herbal remedies are used to treat a large variety of diseases, including blood-related disorders. However, a number of herbal preparations have been reported to cause variations in clotting time, this is mainly by disruption of the coagulation cascade. OBJECTIVE The compiling of plants investigated for effects on the coagulation cascade. METHODS Information was withdrawn from Google...

The aspartic proteases, also called aspartyl and aspartate proteases or acid proteases (E.C.3.4.23), belong to the endopeptidase family and are characterized by the conserved sequence Asp-Gly-Thr at the active site. These enzymes are found in a wide variety of microorganisms in which they perform important functions related to nutrition and pathogenesis. In addition, their high activity and sta...

The whole blood viscosity (WBV) is one of the major independent indicators for the risk of cardiovascular disease, stroke, and peripheral arterial diseases. Furthermore, oxidized LDL molecules are known to cause atherosclerotic plaques in arteries, and it is one of the key components that increase WBV. The present study attempted to reduce WBV by coagulating plasma proteins and lipid molecules ...

A simple method is presented for forming thread-like fibers from highly viscous dextran solutions. Based on the cohesive and adhesive forces between a dextran solution and the substrate to which it is applied, multiple fibers of approximately 10 μm in diameter can be elongated simultaneously. These fibers can be woven into multiple layers to produce fabrics of varying fiber orientations and mec...

A sandwich e.l.i.s.a. method was developed to examine the distribution of lactoferrin in mouse reproductive tract. The lactoferrin concentration was found to be much higher in oviduct, uterus, vagina, vas deferens or epididymis than in serum, but the concentration in ovary, testis, seminal vesicle, prostate or coagulating gland was comparable with that in serum. The existence of lactoferrin in ...

Background: Leaf protein concentrate (LPC) is a cheap and feasible source of high-quality protein. Researchers found the quality LPC similar to first-class food. Tobacco protein-rich leaf but contains high amount nicotine. According studies obtained from tobacco leaves nicotine-free also useful gaining weight in malnourished rats. Methods: Fresh were blended with distilled water different ratio...

PURPOSE We describe the use of chick chorioallantoic membrane (CAM) as a model system for the study of the precision and safety of vitreoretinal microsurgical instruments and techniques. METHODS The CAM was prepared for experimentation with and without its inner shell membrane (ISM) attached for in vivo and in vitro experiments that simulated medical and surgical interventions on the retina. ...
