Previous studies on taste acceptance have been conducted taste-by-taste and with a cross-sectional design. The aim of this study was to longitudinally evaluate the acceptance of sweet, salty, bitter, sour and umami solutions, and a fat emulsion comparatively in a birth cohort from 3 to 20 months old. The acceptance of each taste relative to water was defined using proportional variables that are based on ingestion (IR) or liking evaluated by the experimenter (LR). These data were analyzed with mixed models that accounted for age and subject effects (minimum 152 observations/age/taste; maximum 216)...

The α-oxoaldehyde methylglyoxal is a ubiquitous and highly reactive metabolite known to be involved in aging- and diabetes-related diseases. If not detoxified by the endogenous glyoxalase system, it exerts its detrimental effects primarily by reacting with biopolymers such as DNA and proteins. We now demonstrate that during ketosis, another metabolic route is operative via direct non-enzymatic aldol reaction between methylglyoxal and the ketone body acetoacetate, leading to 3-hydroxyhexane-2,5-dione. This novel metabolite is present at a concentration of 10%-20% of the methylglyoxal level in the blood of insulin-starved patients...

Aging refers to the processes by which the bioavailability/toxicity, isotopic exchangeability, and extractability of metals added to soils decline overtime. We studied the characteristics of the aging process in copper (Cu) added to soils and the factors that affect this process. Then we developed a semi-mechanistic model to predict the lability of Cu during the aging process with descriptions of the diffusion process using complementary error function. In the previous studies, two semi-mechanistic models to separately predict short-term and long-term aging of Cu added to soils were developed with individual descriptions of the diffusion process...
