Percutaneous radiofrequency ablation (RFA) can be as effective as surgical resection in terms of overall survival and recurrence-free survival rates in patients with small hepatocellular carcinoma (HCC). Effectiveness of RFA is adversely influenced by heat-sink effect. Other ablative therapies could be considered for larger tumors or for tumors located near the vessels. In this regard, recent i...

Abstract Surface water and groundwater are polluted with pharmaceuticals, detergents, pesticides, many other substances. Application of ferrates seems to be a perspective option for wastewater treatment as not only powerful oxidizing agents but also an excellent disinfecting coagulating decomposing stable inorganic, organic, biological compounds. Final products their decomposition do include ca...

This study aimed to determine the causes of bitterness problems in white cheese produced by ultrafiltration (UF). To investigate association between with enzyme use or starter culture, was using UF-pasteurized and UF-raw milk two different coagulating enzymes cultures proteolytic activities. Sensory analysis, protein, water-soluble nitrogen, 12% trichloroacetic acid-soluble 5% phosphotungstic n...

Background: Toxoplasma gondii is an intracellular protozoan with worldwide distribution capable of infecting all endothermic vertebrates. Latent toxoplasmosis in man and animals is considered as clinically asymptomatic. The aim of this Study is evaluation of the effects of Toxoplasma gondii on Biochemical Parameters of Reproductive Function in Male Rats. Materials and Methods: A total of 56 mal...

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...
