Macrophages and smooth muscle cells (SMCs) are two of the major reactive cell types in atherosclerosis, a disease characterized by uncontrolled proliferation of SMCs. The present study was designed to determine how dietary oils containing gamma-linolenic acid (GLA) (primrose oil [PO]) and long-chain
This study was conducted to compare the impact of dietary lipids on the ability of macrophages to modulate vascular smooth muscle cell (SMC) DNA synthesis in vitro. C57BL/6 female mice were fed six different diets (6 mice/diet) containing 10% fat from corn oil (CO), borage oil (BO), primrose oil
We previously demonstrated that macrophages isolated from mice fed gamma-linolenic acid (GLA)-enriched diets reduce vascular smooth muscle cell (SMC) proliferation in a cyclooxygenase-dependent fashion and may therefore favorably modulate the atherogenic process. The present study was conducted to
The present study was conducted to evaluate the antiatherogenic effects of dietary gamma-linolenic acid (GLA) (primrose oil) in apolipoprotein E (apoE) genetic knockout mice. Five-wk-old male mice were fed cholesterol-free diets containing 10 g/100 g lipid as corn oil (CO) [control diet, 0 mol/100
Crossbred heifers (n = 120; BW = 368 kg, SD = 39 kg) were used to determine effects of dried distillers grains (DDG) and relative contributions of undegradable intake protein (UIP) and fat (ether extract, EE) in DDG on ADG and forage intake (FI). Heifers rotationally grazed six 3.5-ha, smooth
The present study was undertaken in rats to examine the hepatotoxicity of ingested heated and oxygenated corn oil. Activities of serum glutamic pyruvic transaminase markedly increased in the rats given heated and oxygenated corn oil for two weeks as compared with that of the control group. In the
The intracellular site of synthesis of the fucose-rich polysaccharide slime secreted by corn roots was localized by monitoring the distribution of GDP-fucose:polysaccharide fucosyl transferase activity in subcellular fractions of corn roots. Root tip sections were chopped in the presence of 0.56
Oleogel with tailored viscoelasticity is a great interest for food structuring, while its potential benefits for edible film performance are not clear. In this study, β-sitosterol (0, 5, 10, 15, and 20 wt%)-corn oil oleogel was developed and used in the formation of gelatin-based films. Importantly,
ATP-dependent proton pumps were found in the vesicles of microsomal membrane fractions of maize coleoptiles. Two membrane fractions isolated by density gradient centrifugation were identified by the aid of marker enzymes and electron microscopic analysis. Membrane fraction A largely consisted of
Fibromuscular intimal thickening was seen in the ascending and thoracic aorta of the swine fed 62,500 IU of vitamin D3/kg of diet for three months duration; and after 3 months of vitamin D3 withdrawal, atherosclerotic lesions were found. In rabbits, pronounced aortic smooth muscle cell necrosis
Oxytocin receptor (OTR) regulation has been extensively studied in uterine myometrium and endometrium. However, studies in the cervix are limited. The present studies utilized in situ hybridization and immunocytochemistry to localize OTR mRNA and protein distribution in cervices of nonpregnant
To study the effect of the degree of unsaturation of dietary fatty acids on the production of free radicals and on the vascular smooth muscle tone in rings of the aorta, Sprague-Dawley rats were fed a semipurified diet containing 5% lipids from either corn oil (CO) or menhaden oil (MO) for 8 wk. The
Increased salivary viscosity may be associated with an increase in dental caries. In order to examine this relationship, the caries level in rats was monitored following gastric intubation with tung oil which has been shown to significantly increase salivary viscosity. Tung oil intubation over an
Male Wistar rats of different vitamin A status (total depletion to moderate deficiency) were administered DDT (5 mg/kg/day) or vehicule (corn oil) i.p. daily for 14 days. Vitamin A-dependent protein mannosylation was measured either by in vivo incorporation of [3H]mannose into liver glycoprotein or
The effects of malonaldehyde on the arteries of chickens were studied in a 4-week treatment of a subcutaneous injection of 1 ml of 50% malonaldehyde in corn oil per kg of body weight 3 times a week and/or ad libitum feeding of a 1% cholesterol containing diet. The malonaldehyde had little effect on
