  Alcohol Drinkers Overreport Their Energy Intake in the BIRNH Study: Evaluation by 24-Hour Urinary Excretion of Cations

  摘要：

  Objective: Alcohol drinkers are generally considered to underreport their alcohol intake, but little is known about whether they correctly report their energy intake (EI). We assessed the validity of the reported energy intake of alcohol drinkers using the 24-hour urinary (U) excretion of potassium (K) and sodium (Na) as biomarkers.Methods: A total of 2,124 men and 1,998 women 25 to 74 years of age with a 24-hour urine collection. a random sample of the Belgian Interuniversity Research on Nutrition and Health (BIRNH), were studied. Dietary intake (D), including alcohol consumption, was assessed by a one-day food record, Basal metabolic rate (BMR) was predicted from age gender and weight. As a measure for the degree of reporting error. D-K/U-K, D-Na/U-Na, EI/U-K, Non-alcohol EI/U-Na (NAEI/U-Na), Ei/U-Na, EVU-creatinine and EI/BMR ratios were calculated and compared among non-, moderate and heavy drinkers in both genders.Results: El, NAEI and all seven ratios examined generally increased with the level of alcohol intake in both genders. After adjustment for age, body mass index, smoking and educational level, most ratios were significantly higher in moderate drinkers (p < 0.02 to p < 0.0001) and in heavy drinkers (all p < 0.0001) than in non-drinkers. These differences were most significant in male heavy drinkers. The exceptions were D-K/U-K. D-Na/U-Na and NAEI/U-Na in moderate and female heavy drinkers and EI/U-K in male moderate drinkers. The estimated amount of the overreporting of El by heavy drinkers was 27.8% in men and 13.7% in women.Conclusions: This study provides evidence that El and NAEI obtained from the BIRNH study was overreported among alcohol drinkers, especially among male heavy drinkers. It also indicates that El from alcohol replaced El from food.

  The invention relates to a method for decarboxylating C—C bond formation by reacting carboxylic salts with carbon electrophiles in the presence of transition metal compounds as catalysts. The method represents a decarboxylating C—C bond formation of carboxylic acid salts with carbon electrophiles, wherein the catalyst contains two transition metals and/or transition metal compounds, from which one is present, preferably, in the oxidation step, which are different from each other by one unit, and catalyzes a radical decarboxylation which is absorbed during the second oxidation steps, which are different from each other by two units and catalyzes the two electron processes of a C—C bond formation reaction.

  该发明涉及一种方法，通过在过渡金属化合物存在的情况下，将羧酸盐与碳亲电体反应以脱羧基C—C键形成。该方法代表了一种羧酸盐与碳亲电体的脱羧基C—C键形成，其中催化剂包含两种过渡金属和/或过渡金属化合物，其中一种存在于氧化步骤中，这两种过渡金属或化合物相互之间相差一个单位，并催化在第二氧化步骤中吸收的自由基脱羧反应，这两种过渡金属或化合物相互之间相差两个单位，并催化C—C键形成反应的双电子过程。

  highly stereo- and regioselective hydrometalation of alkynes generating alkenylmetal complex is disclosed for the first time from a reaction of alkyne, carboxylic acid, and a zerovalent group 10 transition metal complex M(PEt(3))(4) (M = Ni, Pd, Pt). A mechanistic study showed that the hydrometalation does not proceed via the reaction of alkyne with a hydridometal generated by the protonation of a

  通过炔烃、羧酸和零价族 10 过渡金属络合物 M(PEt(3))(4) (M =镍、钯、铂）。一项机理研究表明，氢金属化不是通过炔烃与由羧酸与 Pt(PEt(3))(4) 质子化产生的氢化金属反应进行的，而是通过炔烃配位金属络合物与酸。这一发现阐明了长期以来提出的反应机制，该机制通过生成烯基钯中间体和随后在由 Brφnsted 酸和 Pd(0) 配合物的组合催化的各种反应中转化该配合物来进行。
