    Notes: Summary Protein and glycoprotein synthesis and secretion by isolated perfused livers and isolated hepatocytes from control and streptozotocin diabetic rats have been investigated. 3H-Leucine and 14Cglucosamine incorporation were used as markers for protein and glycoprotein synthesis and secretion. Total protein secretion was reduced by 50% in the perfusate (p 〈0.001) and by 36% in hepatocytes (p 〈0.05), but glycoprotein secretion was unchanged in both preparations from diabetic animals. These differences were not due to changes in the available pool sizes of the different labels. On liver fractionation, all membrane components from the liver of diabetic animals had lowered 3H-leucine:14Cglucosamine ratios in relation to the control animals. This was caused by enhanced glucosamine incorporation in relation to that of leucine. It is suggested that whereas protein synthesis is decreased in acutely diabetic rats, the production of glycoproteins is normal and occurs by the same pathway as in control animals.

    Lipoprotein secretion by isolated perfused livers from streptozotocin-diabetic rats (1981)

    Notes: Summary In liver perfusion from sucrose-fed, streptozotocin-diabetic rats there was in comparison with normal animals, a decrease in very low density lipoprotein concentration in the perfusion medium (38.6 ±6.3 versus 64.4±8.4 μg · g liver -1 3h-1, p 〈0.05) and an increase in high density lipoprotein concentration (33.5±6.5 versus 14.0+1.9 μg · g liver-1 3h-1, p〈0.005), which was paralleled by enhanced secretion of apoprotein A-I. The triglyceride: protein ratio was lower in very low density lipoprotein from diabetic animals (8.8 versus 13.4). Analysis of the apoprotein composition showed that diabetic very low density lipoprotein lacked arginine-rich protein (apo-E) and apo-C peptides; diabetic high density lipoprotein also lacked arginine-rich protein but contained more A-IV and apo-C-peptides. This may indicate net transfer of C peptides to high density lipoprotein from the degradation of very low density lipoprotein particles. The ratio of 3H-leucine: 14C-glucosamine incorporation was decreased in all diabetic lipoprotein classes suggesting increased glycosylation of apoproteins. These changes in particle composition may influence lipoprotein metabolism in diabetes through their effects on lipoprotein lipase and lecithin cholesterol acyl transferase activity, plasma half-life and tissue binding.

    The influence of soil compaction and the removal of organic matter on two native earthworms and soil properties in an oak-hickory forest (2000)

    Notes: Abstract  Earthworms may alter the physical, chemical, and biological properties of a forest soil ecosystem. Any physical manipulation of the soil ecosystem may, in turn, affect the activities and ecology of earthworms. The effects of removing organic matter (logs and forest litter) and severely compacting the soil on native earthworm species were measured in a central USA hardwood region (oak-hickory) forest in the Missouri Ozarks (USA). Soils in this region are characterized by a cherty residuum that is primarily of the Clarksville series (Loamy-skeletal, mixed, mesic Typic Paledults). Earthworms were collected from 0–15 cm depth each spring and fall for 2 years by handsorting, and densities were determined on a per meter square basis. Two native earthworm species, Diplocardia ornata and Diplocardia smithii, were dominant on this site. Organic matter removal decreased the average individual biomass of both species. However, both species responded differently to soil compaction. Soil compaction affected D. ornata adversely and D. smithii favorably. This suggested that the degree of soil compaction was not as restrictive with respect to D. smithii (2 mm diameter) as to D. ornata (5 mm diameter). Moreover, the apparently improved soil environmental conditions resulting from the remaining organic matter in compacted soil enhanced the population and growth of D. smithii. Sampling position on the landscape affected D. ornata but not D. smithii. Soil microbial biomass C and soil microbial biomass N were decreased under soil compaction when the organic matter was removed. Other factors influencing the ecology and activity of these two species will require further study.

    Antipyrine disposition in obesity: evidence for negligible effect of obesity on hepatic oxidative metabolism (1995)
    Springer

    Notes: Abstract Following an overnight fast and 2 days of abstention from caffeine, a single 1.0-g oral dose of antipyrine was administered to 20 obese but otherwise healthy subjects (group A) and 11 healthy volunteers (group B). Weight, Body Mass Index (BMI) and % of Ideal Body Weight (IBW) were significantly greater in the obese than in the lean group. (Mean 110.4 vs 62.7 kg; 38.5 vs 22.3 kg · m−2 and 181vs 106 % respectively). In a subgroup of 6 obese subjects (group C) antipyrine was given again 11.3 months later after a 29.8 kg mean weight loss. Antipyrine apparent volume of distribution (V) and elimination half-life (t 1/2) were significantly greater in the obese than in the lean group (V 49.9 vs 34.3 l respectively; t 1/2 15.5 vs 12.0 h respectively), but its clearance rate (CLo) values were similar. V corrected for total body weight was significantly reduced in group A than in group B (0.45 vs 0.55 l · kg−1 respectively). Stratified comparison of antipyrine pharmacokinetics between obese and lean subjects according to age, gender and smoking habits did not alter the overall results. In group C, weight reduction was associated with a significant decrease in antipyrine V (from 51.8 to 47.5 l) and t 1/2 (from 15.1 to 12.7 h), and a non-significant increase in antipyrine CLo. We conclude that in severely obese subjects, antipyrine total V is mildly increased but V corrected for total body weight is significantly decreased. In addition, obesity is associated with a slight prolongation of antipyrine t 1/2 whereas its CLo is unaltered. These findings may indicate that obesity, even in its extreme form, has a negligible effect on the oxidative metabolic capacity of the liver.

    A new crystal form of bovine heart ubiquinol: cytochrome c oxidoreductase: determination of space group and unit-cell parameters (1995)

    Notes: Ubiquinol:cytochrome c oxidoreductase, the middle segment of the mitochondrial respiratory chain, is a multi-subunit transmembrane redox enzyme. The purified protein from beef heart mitochondria has been crystallized by three groups in three different forms, but progress toward a structure has been hampered by the limited order (resolution) of the crystals. It has been found that under certain conditions the enzyme crystallizes in a new form suitable for X-ray diffraction studies. These crystals belong to space group C2221 in the orthorhombic system. The cell dimensions are a = 384, b = 118 and c = 177 Å. These new crystals at present diffract to 3.8 Å at best. This is not significantly better than hexagonal [P61(5)22] crystals grown, but the new crystals have the advantage of less spot overlap because of face-centered packing which results in systematic extinctions. More importantly, the availability of the same enzyme in multiple crystal forms may allow phase refinement and extension by the method of molecular replacement.
