Age differences in the allocation of study time account for age differences in memory performance.

Abstract: How aging affects the utilization of monitoring in the allocation of study time was investigated by having adults learn paired associates during multiple study-test trials. During each trial, a subject paced the presentation of individual items and later judged the likelihood of recalling each item on the upcoming test; after all items had been studied and judged, recall occurred. For both age groups in Study 1, (1) people’s judgments were highly accurate at predicting recall and (2) intraindividual correlations between judgments (or recall) on one trial, and study times on the next trial were negative, which suggests that subjects utilized monitoring to allocate study time. However, the magnitude of these correlations was less for older than for younger adults. Study 2 revealed that these differences were not due to age differences in forgetting. Results from both studies suggest that older adults do not utilize on-line monitoring to allocate study to the same degree as younger adults do, and that these differences in allocation contribute to age deficits in recall.

Assessment of Degradation and Intestinal Cell Uptake of Carotenoids and Chlorophyll Derivatives from Spinach Puree Using an In Vitro Digestion and Caco-2 Human Cell Model

Abstract: Although numerous studies have demonstrated the health benefits of chlorophyll derivatives, information regarding the digestion, absorption, and metabolism of these phytochemicals is quite limited To better understand the digestion of these pigments, green vegetables including fresh spinach puree (FSP), heat- and acid-treated spinach puree (HASP), and ZnCl(2)-treated spinach puree (ZnSP) were subjected to an in vitro digestion method which simulates both the gastric and small intestinal phases of the process Native chlorophylls were converted to Mg-free pheophytin derivatives during digestion Conversely, Zn-pheophytins were completely stable during the digestive process Transfer of lipophilic chlorophyll derivatives, as well as the carotenoids lutein and beta-carotene, into the aqueous micellar fraction from the food matrix was quantified Micellarization of total chlorophyll derivatives differed significantly (p 005) Intestinal cell uptake of micellarized pigments was investigated using HTB-37 (parent) and clonal TC7 lines of human Caco-2 cells Medium containing the pigment-enriched fraction generated during digestion was added to the apical surface of fully differentiated monolayers for 4 h Pigments were then extracted from cells and analyzed by C18 HPLC with photodiode array detection Both Caco-2 HTB-37 and TC7 clone cells accumulated 20-40% and 5-10% of micellarized carotenoid and chlorophyll derivatives, respectively These results are the first to demonstrate uptake of chlorophyll derivatives by human intestinal cells and to support the potential importance of chlorophylls as health-promoting phytochemicals

Religion/Spirituality and Adolescent Psychiatric Symptoms: A Review

Abstract: The aim of the current article is to review the literature on religion and spirituality as it pertains to adolescent psychiatric symptoms. One hundred and fifteen articles were reviewed that examined relationships between religion/spirituality and adolescent substance use, delinquency, depression, suicidality, and anxiety. Ninety-two percent of articles reviewed found at least one significant (p < .05) relationship between religiousness and better mental health. Evidence for relationships between greater religiousness and less psychopathology was strongest in the area of teenage substance use. Methods of measuring religion/spirituality were highly heterogeneous. Further research on the relationship of religion/spirituality to delinquency, depression, suicidality, and anxiety is warranted. Measurement recommendations, research priorities, and clinical implications are discussed.
