Hydrolysis of 2,4-dithiophenobarbital
Hydrolysis of 2,4-dithiophenobarbital in aqueous solutions of pH 2 - 12 was investigated at 40 and 60OC using UV spectrophotometry. The values of reaction order, rate constants, pKa1 and pKa2 and activation energy were determined. The preliminary estimation of degradation products was accomplished using thin layer chromatography. The major products were isolated by circular chromatography and identified by spectroscopic and classical methods
Stability of 2-thiophenobarbital and its N-methyl derivatives in the presence of \beta-cyclodextrin
Assessment of the chromatographic lipophilicity of eight cephalosporins on different stationary phases
DietaryâPhysical Activity Patterns in the Health Context of Older Polish Adults: The âABC of Healthy Eatingâ Project
The study aimed to analyze the dietaryâphysical activity patterns (D-PAPs) in the health context of Polish people aged 60+ years. A total of 418 respondents across Poland were recruited; however, the final analysis included 361 women and men aged 60â89 years old. D-PAPs were derived using a principal component analysis (PCA); input variables were the frequency of consumption of 10 food groups and physical activity. Finally, three D-PAPs were identified: âPro-healthy eating and more-activeâ, âSweets, fried foods and sweetened beveragesâ, and âJuices, fish and sweetened beveragesâ. We developed the Functional Limitations Score (FLS) using the Mini Nutritional Assessment (MNAÂź). A logistic regression was applied to verify the association between the D-PAPs and health-condition outcomes. Older adults were more likely to adhere to the upper tertile of the âPro-healthy eating and more-activeâ pattern, with good/better self-reported health status in comparison with their peers (OR = 1.86) or with good/very good self-assessed appetite (OR = 2.56), while this was less likely for older adults with malnutrition risk (OR = 0.37) or with a decrease in food intake (OR = 0.46). Subjects with a decrease in food intake (OR = 0.43), who declared a recent weight loss (OR = 0.49), or older adults in the upper tertile of the FLS (OR = 0.34) were less likely to adhere to the upper tertile of the âSweets, fried foods and sweetened beveragesâ pattern. The decrease in food intake due to a loss of appetite or chewing or swallowing difficulties was inversely associated with the âPro-healthy eating and more-activeâ pattern characterized by a relatively high frequency of consumption of vegetables, fruit, water, dairy, and grains and a high physical activity. In the interest of the good nutritional status and health of older adults, special attention should be paid to removing limitations in meal consumption, including improved appetite
