Oral administration of vitamin A (30,000 IU daily for 2 days) to young rats caused a marked increase in hepatic glycogen, cholesterol, and glycerides, while hepatic phospholipid content remained almost unaltered. In an examination of the pathogenesis of the lipid accumulation, it was found that more glucose-(14)C was incorporated into liver lipids in vitamin A-fed rats, whereas incorporation of...

Omega-Cyclohexyl undecanoic acid and omega-cyclohexyl tridecanoic acid were found in 10 strains of acido-thermophilic bacteria isolated from different Japanese hot springs. These unusual fatty acids were found in the esterified form in glyceride type complex lipids and constituted 74 to 93% of the total fatty acids in the bacteria. The fatty acids other than omega-cyclohexyl fatty acids found w...

Lipid accumulation is a hallmark of corpus luteum regression and we characterized lipids stored in rat corpora lutea of pregnancy between days 21 and 24 post coitum, the period of luteolysis. A 10-fold rise in lutein triglyceride concentrations occurred between days 21 and 24, which represented the major alteration in luteal lipid metabolism during luteolysis, coinciding with the appearance of ...

We have tested the hypothesis proposed by Costa, Lyles, and Ullmich.(Effect of Human and Experimental Cancer on the Conversion of 14CTripalmitin to 14CO2.Cancer (Phila.), 38: 1259—1 265, 1976) that the transport and/or oxidation of tn glyceride fatty acids is markedly impaired in rodents bearing a growing s.c. carcinoma. Specifically, we have tested whether oxidation of triglyceride fatty aci...

In 1938 Schantz, Elvehjem, and Hart (1) reported that rats, calves, and pigs which received liquid skim milk as their sole diet excreted a considerable amount of galactose in the urine. No such excretion occurred when whole milk was fed. In studies with the rat it was found that the addition of 3 to 4 per cent of fat to the skim milk completely prevented the urinary loss of galactose, and furth...

Interactions of high density lipoproteins (HDL) with very low (VLDL) and low (LDL) density lipoproteins were investigated during in vitro lipolysis in the presence of limited free fatty acid acceptor. Previous studies had shown that lipid products accumulating on lipoproteins under these conditions promote the formation of physical complexes between apolipoprotein B-containing particles (Biochi...

The effects of sublethal concentrations 0.1, 0.5, and 1.2 µg mL(-1)of the chitin synthesis inhibitor, hexaflumuron, on larval growth and development, the count and proportion of hemocytes, and carbohydrate content (trehalose and glyceride) in hemolymph were investigated in the cutworm, Spodoptera litura (Fabricious) (Lepidoptera: Noctuidae). When 3(rd) instar larvae were subjected to the sublet...

In the absence of glucose, significant amounts of labeled pyruvate were converted to glyceride-glycerol by rat epididyma1 fat pads in uifro. Using specifically labeled pyruvate-“C we found twice as much C-2 incorporated into glycerideglycerol as C-l. Although this ratio is not affected by changes in dietary conditions, the amount of pyruvate lncorporated into glyceride-glycerol is decreased j-f...

conclusions amateur motocross riders had significant anaerobic metabolism demands and had reduced handgrip strength following a training session. these data suggest an importance of physical training aimed at improving anaerobic and neuromuscular performance of the upper limbs in amateur motocross riders. background motocross is one of the most popular motorized off-road sports, characterized b...
