High impact polystyrene (HIPS)/corn starch blends were prepared in presence of glycerol as a plasticizer via melt extrusion process by a twin-screw extruder. The novelty of this work is first, because of the use of pre-gelatinized corn starch as modified one and second, the procedure of making blends by extruder which makes it ease of access and also industrially possible. The blends were then ...

Introduction: Skeletal staining is an important part of anatomical studies which can evaluate macroscopic disorders in bones and cartilages development. The aim of the present article is to illustrate two distinct protocols by all details in order to stain skeletal system of the lab animals in all ages of their lives so it becomes easy for future studies in this field. Methods: In this pa...

The amino acid-producing organism Corynebacterium glutamicum cannot utilize glycerol, a stoichiometric by-product of biodiesel production. By heterologous expression of Escherichia coli glycerol utilization genes, C. glutamicum was engineered to grow on glycerol. While expression of the E. coli genes for glycerol kinase (glpK) and glycerol 3-phosphate dehydrogenase (glpD) was sufficient for gro...

1. The possible role of glycerol as a precursor in neonatal gluconeogenesis in the rat was investigated by recording the activities of glycerol kinase and l-glycerol 3-phosphate dehydrogenase in the liver, kidney and other tissues around birth and during the neonatal period. 2. Blood glycerol concentrations in the neonatal rat are high. 3. There is a marked increase after birth in the ability o...

1. Glycerol kinase (EC 2.7.1.30) is shown to catalyse a non-equilibrium reaction in rat liver; and, as it is the first enzyme in the pathway metabolizing glycerol, its properties may be pertinent to the metabolic regulation of glycerol uptake and utilization by this tissue. 2. The properties of hepatic glycerol kinase were studied by using a radiochemical technique to measure the enzyme activit...

Jensen, Michael D. Regional glycerol and free fatty acid metabolism before and after meal ingestion. Am. J. Physiol. 276 (Endocrinol. Metab. 39): E863–E869, 1999.—We measured splanchnic and leg glycerol [and free fatty acid (FFA)] uptake and release in 11 healthy volunteers before and after meal ingestion to assess whether regional FFA-to-glycerol release ratios mirror systemic release ratios. ...

STEELE, R., B. WINKLER, AND N. ALTSZULER. Inhibition by infused glycerol of gluconeogenesis from other precursors. Am, J. Physiol. 22 l(3) : 883-888. 1971 .-Plasma glycerol contributes 20% of the carbon of glucose released to the blood by the liver in the 6to 7-dayfasted dog (shown by use of glycerol-UJ4C). This increases to 63y0 when bulk glycerol infusion increases total glycerol uptake from ...

BERGMAN, E. N. Glycerol furnouer in the nonpregnant and k&tic pregnant sheep. Am. J. Physiol. 215(4): 865-873. 1968.Labeled glycerol was infused intravenously into three groups of sheep: fed, fasted, and twin-pregnant hypoglycemic and ketotic. The turnover time of the free glycerol pool was rapid in all animals (15-l 8 min). Mean glycerol turnover rates were 0.25 mmole/hr per kg3i4 in fed anima...
