Sugarcane can be very susceptible to damage by freezes. Freeze-deteriorated cane can cause problems in processing and sometimes leads to a factory shut-down. This study was undertaken during the 2000/2001 harvest season to assess the cold tolerance performance of six commercial sugarcane varieties and to establish new and more sensitive criteria to measure cold tolerance. Two varieties CP 70-32...

Mucopolysaccharidoses are inherited metabolic disorders resulting in the dysfunction of enzymes involved in the degradation of glycosaminoglycans, leading to severe clinical symptoms and a significantly shortened life span of patients. Flavonoids are recognized as glycosaminoglycan metabolism modulators, able to correct glycosaminoglycan cell storage. Therefore, the aim of this work was the dev...

Abstract This study reports results on the estimated magnitude of changes in P sorption isotherms clayey mud sediments when performed using (1) freeze-dried instead fresh sediment samples and (2) artificial sea water (ASW) ambient near-bottom water. The used differed their sorption. For isotherms, were equilibrated for 48 h solutions varying concentration whereafter amount sorbed or desorbed wa...

Here, we have studied the osmotic parameters of erythrocytes frozen in composition-modified media with glycerol and 1,2-propanediol. A decreased concentration a cryopreservative an increased content impermeable protective component sorbitol were established to affect erythrocyte characteristics at different stages freezing hypothermic storage. Reduction 1,2-propanediol NaCl concentrations when ...

The concentration of dairy products is widely applied in manufacturing due to obtaining with the high dry matter, added value, reduced volume, and an increase shelf-life. Traditional thermal processes are most industries, however, temperatures can damage bioactive compounds milk, addition modifying physicochemical, sensory, nutritional characteristics concentrated products. This review summariz...

Biodegradable polymers have been widely used as scaffolding materials to regenerate new tissues. To mimic natural extracellular matrix architecture, a novel highly porous structure, which is a three-dimensional interconnected fibrous network with a fiber diameter ranging from 50 to 500 nm, has been created from biodegradable aliphatic polyesters in this work. A porosity as high as 98.5% has bee...

In experiments in which liver and testis freeze-stops were performed on pentobarbital-anaesthetized rats, ethanol (1.5 g/kg body wt.) reduced plasma testosterone concentration from 13.1 to 3.2 nmol/litre. 4-Methylpyrazole abolished the ethanol-induced hepatic and testicular increase in the lactate/pyruvate ratio, and the testicular acetaldehyde level, but did not diminish the reduction in plasm...

We have studied dodecylmaltoside-induced echinocyte-spheroechincyte-spherocyte shape transformation and membrane vesiculation using transmission electron microscopy (TEM) on freeze-fracture replicas. It is indicated that spherical erythrocyte shape at higher dodecylmaltoside concentration is formed due to loss of membrane in the process where small, mostly tubular nanovesicles are released pred...
