During aging there is a tendency towards hyperlipidemia and changes in the distribution of lipoproteins. A decline in the functioning of the body's antioxidant defense system is also observed at this time. The objective of this study was to establish the relationship between serum concentrations of total cholesterol and fractions, triglycerides, and Vitamins C and E. 61 adults over 60 years of age were evaluated from January to March, 2006. Nutritional status was diagnosed by BMI (WHO); serum levels of triglycerides (TG), total cholesterol (TC) and fractions (HDL-c and LDL-c) were determined by enzyme method; Vitamin C (colorimetric method) and Vitamin E by HPLC. ATPIII values were used as a reference for risk of TG, TC, HDL, LDL-c, vitamin C: > 0.9 mg/dL (normal), < 0.9 mg/dL (deficit); vitamin E: = 1300 microg/dL (normal), 1300 = microg /dL (deficit). Consumption of vitamins C and E were estimated by the direct weighing method 3 days per week. According to BMI, 19.7% had nutritional deficit, 39.3% overweight, and 11.5% obesity. TG, TC, LDL-c levels were at risk in females, and HDL-c in both genders. Prevalence of risk for heart disease was: TG (45.2%), HDL-c (51.1%), and LDL-c (52.5%). Consumption and serum levels of vitamin E were low in both genders. There was no association between variables. A significant and positive correlation between TG, TC, LDL-C, serum vitamin E, and BMI was observed. The female group showed overweight, hypertriglyceridemia and hypercholesterolemia, HDL-c and LDL-c at risk, and vitamin E deficiency, all of which are important risk factors for cardiovascular disease in this age group.

Background: This study aims to investigate the association between vitamin D levels and the risk of severe acute exacerbations of chronic obstructive pulmonary disease (AECOPD).
Methods: We conducted a prospective observational study with 636 COPD patients admitted for exacerbations between January 2021 and December 2022. Patients were categorized based on serum 25-hydroxyvitamin D levels: severe deficiency (<10 ng/mL), deficiency (10-20 ng/mL), insufficiency (20-30 ng/mL), or sufficiency (>30 ng/mL).

Unlabelled: Despite the remarkably high antioxidant activity of tocopherols, their applications in the food industry are limited because of their instability under various conditions. Complexes of α-tocopherol (α-TQ) or α-tocopheryl acetate (α-TQA) with β-cyclodextrin (β-CD) or starch were prepared and characterized by UV-vis, IR and thermal analysis. Oxidative stability of α-TQ and α-TQA against HO was 74.

Unlabelled: The potential of (), an underutilized plant rich in medicinal and nutritional value, for producing ready-to-serve (RTS) beverages was explored. The research investigated commercial processing techniques for extracting fruit juice and the impact of stabilizers such as pectin (low and high), xanthan gum, and sodium alginate on beverage quality. Sodium alginate, chosen for its sedimentation rate and sensory acceptability, was further optimized in RTS formulations.

Objective: Vitamin B6 is involved in regulating a variety of biological reactions in cell metabolism, and possesses antioxidant and anti-inflammatory biological functions. 5'-pyridoxal phosphate (PLP) is the main biologically active form of vitamin B6. There is currently no research on the correlation between serum PLP levels and chronic obstructive pulmonary disease (COPD) prevalence.
