Oxidation Of Glucose

Embryos were collected from superovulated donors at various intervals from onset of oestrus, ranging from Day 1.5 to Day 6. In addition, blastocysts obtained from the culture of 1-cell embryos collected in vivo or of oocytes matured and fertilized in vitro were used to assess the effects of in vitro manipulation and culture on glucose utilization. Glycolytic activity was determined by the conversion of [5-3H]glucose to 3H2O, and oxidation of glucose was determined by the conversion of [U-14C]glucose to 14CO2. Glucose utilization increases significantly from the 8-cell stage and during compaction and blastulation. Glucose oxidation was at a relatively low level (5-12% of total utilization) compared with glycolysis. No difference was observed between the glycolytic activity of blastocysts derived from in vivo or in vitro sources. However, glucose oxidation was lower (P less than 0.05) in blastocysts derived from the culture of 1-cell embryos or from oocytes matured and fertilized in vitro. Exogenous tricarboxylic acid cycle substrates (i.e. pyruvate and lactate supplied in the medium) affected the level of glucose oxidation.

Fat Feeding

Triacylglycerol (TG) stored in cytoplasmic lipid droplets of hepatocytes was labeled by in vivo [1-(14)C]oleic acid injection to study the effect of a high-fat diet on its incorporation into very-low-density lipoproteins (VLDL). Compared with the control diet, hepatocytes of fat-fed rats 1) contained 7.6 times more cytoplasmic (floating fat) TG and 1.9 times more endoplasmic reticulum (microsomal) TG; 2) had 8 and 6 times lower TG specific activities in cytoplasm and endoplasmic reticulum, respectively; 3) incorporated 22% less 14C label into hepatocyte esterified lipids (TG, cholesterol, phospholipid); 4) secreted 48 and 33% less radioactive and total VLDL-TG, respectively; 5) oxidized more cytoplasmic TG-fatty acid (FA); and 6) showed a 50% decreased total utilization of stored TG-FA. With both diets, the lysosomal inhibitor chloroquine concomitantly decreased productions of labeled VLDL-TG, CO2, and acid-soluble oxidation products. The decreased incorporation of stored TG into VLDL-TG appreciably contributes to the overall inhibition of hepatic VLDL secretion by fat feeding. It appears to be related to the decreased mobilization rate of stored TG and its increased channelling toward oxidation.

Clostridium Thermosaccharolyticum

The major objective of this project is to achieve the direct microbiological conversion of cellulosic biomass to liquid fuel, ethanol. Within the scope of this objective, it is also the intent to maximize the conversion efficiency of ethanol production from biomass. This can be achieved through the effective utilization of both the cellulosic (six-carbon sugar) and hemicellulosic (five-carbon sugar) fractions in biomass. The degradation of cellulosic biomass is achieved through the use of a thermophilic and anaerobic bacterium, Clostridium thermocellum . This microorganism is unique in that it is able to hydrolyse both the cellulosic and hemicellulosic fractions of biomass but, unfortunately, it is not able to metabolize the pentoses. Therefore, to achieve total utilization of biomass, a second thermophilic and anaerobic microorganism, Clostridium thermosaccharolyticum , has been under study owing to its ability to convert pentoses to ethanol. Mutation, selection and adaption programmes have yielded ethanol tolerant strains of both organisms. A fermentation process using mutant strains of the anaerobic, thermophilic bacteria Clostridium thermocellum and Clostridium thermosaccharolyticum has been investigated for the direct production of ethanol from agricultural cellulosics. Through strain improvements for increased ethanol tolerance and catabolite selectivity, alcohol yields of 85% of the theoretical maximum have been obtained from solka floc with mixed culture. The method of isolation and the performance of these improved strains on both refined cellulosics and a realistic biomass, corn [maize] stover, is presented in detail.

Abstract: Limited research exits on utilization and cost-effectiveness of acupuncture among underserved communities, and virtually no evidence has been published with respect to refugee populations. In this study, we examined the relationship between acupuncture and the total utilization of primary care services in a cohort of refugee patients with chronic pain.: We retrospectively reviewed the medical records of 16 refugee patients with chronic pain at Boston Medical Center (BMC). The research was IRB-approved. Demographics and total charges associated with primary care over 18 months were collected.: Total charges associated with primary care services decreased by 50.2% in our refugee cohort in the 12 months following acupuncture treatment, equivalent to a savings of $691 per patient per month.: This preliminary review demonstrated a statistically significant decrease in total charges associated with primary care following acupuncture treatment (p=0.0308). This study suggests the need for further investigation of the relation between acupuncture and refugees with chronic pain, as well as the financial implications of this relationship. It is unclear why refugees may seek fewer primary care services after acupuncture treatment. Additional study is needed to further explore whether this relationship is generalizable to other hospital services and to other patient populations.

Hepatocytes were prepared from livers of ob/ob (obese diabetic) mice and their lean (OB/OB) siblings that had been fasted for 24 h. The hepatocytes were incubated with [U-14C, 2-3H]-, [U-14C, 3-3H]-, and [U-14C, 6-3H]glucose at concentrations from 20 to 120 mM. 14C was recovered mainly in CO2, glycogen, and lactate. Tritium was recovered in water and glycogen. The yield in labeled products from [2-3H]glucose ranged from two to three times that from [U-14C]glucose. The yields from [3-3H]- and [6-3H]glucose were similar, and 1.3-1.7 times that from [U-14C]glucose. At 40 mM, total utilization of glucose by obese mice was about twice that for lean mice, but there was little difference at 120 mM. The rate of recycling between glucose and glucose 6-phosphate was calculated. An equation to calculate the rate of recycling of glucose from the 2-3H/U-14C ratio in glycogen is derived in the APPENDIX. Our results show that 1) the utilization of glucose by hepatocytes from obese diabetic mice exceeds that of their lean controls, 2) the rate of glucose phosphorylation in both groups greatly exceeds glucose uptake and the rate of glycogen synthesis, 3) glucose phosphorylation represents a difference between a high glucokinase rate and hydrolysis of glucose 6-phosphate, and 4) recycling of glucose carbon between glucose 6-phosphate and pyruvate occurs within mouse hepatocytes.
