Studies on changes in lipid profiles of the rat gastric mucosa with stress ulcers.

Gastric mucosal lipid patterns were studied in normal and in restrained rats which developed mucosal erosions. Organic solvent extraction, silicic acid column, and thin-layer chromatography were employed to separate and gas-liquid chromatography and spectrophotometry to quantitize the individual lipid components. Chemical analysis revealed profound alterations in the mucosal lipid profiles of rats with gastric mucosal erosions. Cholesterol esters were markedly elevated, cholesterol, free fatty acids and phosphatidylethanolamine were markedly lower in the extracts of ulcerated tissue, and the titer of lysophospholipids was about eight times higher than in the controls. Lipid phosphorus was elevated in stressed rats. The amount of neutral glycolipids was similar for both groups, but tetra- and oligohexoside ceramides, which were present in the gastric mucosa of the control rats, were virtually absent from the ulcerated mucosa. In contrast to the alterations in lipid profile mentioned above, the total lipid weight per tissue preparation was very similar for the ulcerated and normal control groups.

Serum lipid profiles in patients of myocardial infarction in the Chandigarh area (Northern India).

To study the incidence of hyperlipoproteinaemia in patients with myocardial infarction (MI) in the Chandigarh area, estimations of various lipids have been carried out in 83 patients. A serial study has been carried out in 31 patients. Serum lipoproteins and uric acid were also estimated. Results show an incidence of only 18% hypercholesterolaemia in patients with MI and 15% in normal subjects. Age-wise distribution of hypercholesterolaemia was slightly higher in 41-60 years old patients when compared with other age groups. No other abnormality in lipid profile was observed. Hyperuricaemia was not observed. These results, therefore, differ markedly from those of similar studies published from the western world.

Probiotic supplementation improves body composition, lipid profiles, and fatty acid metabolism in combat sports athletes during the weight reduction phase.

PURPOSE: Pre-competition weight control for combat sports athletes may alter body composition and fatty acid metabolism. Probiotics have shown potential to regulate overall metabolism; however, their specific effects on fatty acid metabolism during weight control in athletes remain unclear. METHODS: Thirty-two combat sports athletes participating in the 4-week weight reduction period were assigned to either the probiotic group (Group E) or the placebo group (Group C). Body composition, lipid profiles, and fatty acid metabolism were measured before and after the 4-week weight reduction phase. RESULTS: All the athletes experienced a decrease in body weight, body mass index (BMI), body fat percentage, and muscle mass following the 4-week weight loss intervention. Notably, a more significant reduction in body fat percentage (p&#x2009;<&#x2009;0.05) was observed, along with lower levels of triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C), specifically in Group E. Weight loss intervention resulted in increased levels of short-chain fatty acids (SCFAs), specifically acetic acid, propionic acid, and butyric acid. Notably, Group E exhibited higher mean values for SCFAs compared to Group C (p&#x2009;<&#x2009;0.05). Additionally, the serum levels of &#x3b3;-linolenic acid and 8,11,14-eicosatrienoic acid were significantly reduced in Group E (p&#x2009;<&#x2009;0.05). In contrast, the majority of free fatty acids (FFAs) showed significant increases, with greater magnitudes of change observed in Group C (p&#x2009;<&#x2009;0.05). CONCLUSION: Probiotic supplementation can improve body composition, enhance SCFAs levels, and decrease circulating FFAs in combat sports athletes, suggesting that probiotics may have a beneficial impact on pre-competition weight management.

Effects of 12 weeks of resistance and concurrent training with graded protein intakes on lipid profile, kidney and liver biomarkers in middle-aged to older women.

PURPOSE: To examine secondary lipid, kidney-related, and liver-enzyme responses to three protein intakes during resistance training (RT) alone or the same RT plus cycling (CT) in middle-aged to older women. METHODS: In this randomized 2&#xd7;3 factorial trial, 108 women aged 40-77 years were assigned to RT or CT and 0.8, 1.6, or 2.2 g kg-1 d-1 protein for 12 weeks. This complete-case secondary analysis included 83 participants. Linear mixed-effects models tested Time &#xd7; Training, Time &#xd7; Protein, and Time &#xd7; Training &#xd7; Protein effects, with false-discovery-rate-adjusted omnibus tests and Holm-adjusted contrasts. RESULTS: Triglycerides, total cholesterol, LDL-C, and apolipoprotein B decreased and HDL-C increased in all conditions. Lipid changes differed by protein condition, and several were more favorable with CT; however, CT comprised RT plus additional cycling and greater exercise exposure. Urea, blood urea nitrogen, creatinine, the blood urea nitrogen-to-creatinine ratio, and cystatin C increased, whereas three eGFR estimates decreased. Responses differed mainly between 0.8 and the two higher protein conditions, with little evidence of differences between 1.6 and 2.2 g kg-1 d-1. ALT, AST, and GGT differed by protein condition; AST and GGT also showed training-dependent responses. CONCLUSIONS: The dietary and exercise interventions modified lipid and clinical-chemistry responses. Because energy and food composition were not fully matched and CT added cycling to RT, the findings do not isolate protein dose or exercise modality. Changes in eGFR estimates and liver enzymes do not establish organ injury or long-term safety.
