TL;DR: It is concluded that food intake during the nocturnal period is correlated with negative effects on the sleep quality of healthy individuals and food intake near the sleeping period (dinner and late night snack) was negatively associated with sleep quality variables.
Abstract: Study Objectives: The purpose of this study was to analyze the relationship between food intake and sleep patterns in healthy individuals. Methods: Fifty-two healthy volunteers (27 women and 25 men) were recruited to participate in the study. Volunteers underwent sleep evaluation through nocturnal polysomnography and completed a 3-day food diary to evaluate food intake. Results: No differences in sleep patterns were observed in either gender, except in the percentage of stage 1 sleep, which was greater in men. Different correlations were observed between sleep and dietary variables according to gender. The correlation between dietary and sleep variables in men indicated a negative relationship between nocturnal fat intake and the sleep latency, including REM sleep. The percentage of nocturnal fat intake correlated with sleep effisleep latency, REM latency, stage 2 sleep, REM sleep, and wake after sleep onset (WASO) in women. The percentage of nocturnal caloric intake correlated with sleep latency and effi ciency in women. Conclusions: We conclude that food intake during the nocturnal period is correlated with negative effects on the sleep quality of healthy individuals. Indeed, food intake near the sleeping period (dinner and late night snack) was negatively associated with sleep quality variables. More studies are necessary to elucidate the real effect of food intake on sleep.

TL;DR: In this article, a superacid sulfated titania catalyst, TiO 2 /SO 4 (TS-series), with different sulfate concentrations was used for methanolysis of soybean and castor oils.
Abstract: Superacid sulfated titania catalyst, TiO 2 /SO 4 (TS-series), have been prepared via the sol–gel technique, with different sulfate concentrations. The relation of structure and catalytic activity of the prepared material have been evaluated. The obtained material was characterized by several techniques, as infrared and Raman absorption spectroscopy, pyridine-adsorption infrared spectroscopy, thermogravimetric analyses and obtention of N 2 adsorption–desorption isotherms. The catalyst that exhibits the highest catalytic activity in the methanolysis of soybean and castor oils at 120 °C, for 60 min (40% and 25%, respectively) was that which displayed the highest specific surface area, average pores diameter and pore volume, and highest percentage in sulfate groups (TS-5).
