Adult attachment and the perception of facial expression of emotion.

Adult attachment orientation has been associated with specific patterns of emotion regulation. The present research examined the effects of attachment orientation on the perceptual processing of emotional stimuli. Experimental participants played computerized movies of faces that expressed happiness, sadness, and anger. Over the course of the movies, the facial expressions became neutral. Participants reported the frame at which the initial expression no longer appeared on the face. Under conditions of no distress (Study 1), fearfully attached individuals saw the offset of both happiness and anger earlier, and preoccupied and dismissive individuals later, than the securely attached individuals. Under conditions of distress (Study 2), insecurely attached individuals perceived the offset of negative facial expressions as occurring later than did the secure individuals, and fearfully attached individuals saw the offset later than either of the other insecure groups. The mechanisms underlying the effects are considered. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Adult age differences in temporal and item memory.

Three experiments tested whether the relationship between age differences in temporal and item memory depends on the degree to which the item memory measure relies on memory for context. The authors predicted a stronger relationship of temporal memory to free recall than to recognition memory. Results showed that age differences in temporal memory could be eliminated after controlling for free recall but not recognition memory performance. Under some conditions recognition memory accounted for a significant portion of age-related variance in temporal memory. These results challenge past research that has interpreted age differences in temporal and item memory as independent and suggest that a generalized decline in context memory may underlie reduced performance in older adults on all types of memory tests.

Factor structure of the Brief Symptom Inventory--18 in adult survivors of childhood cancer: Results from the Childhood Cancer Survivor Study.

The factor structure of the Brief Symptom Inventory-18 (BSI-18; L. R. Derogatis, 2000) was investigated in a sample of adult survivors of childhood cancer enrolled in the Childhood Cancer Survivor Study (CCSS; N = 8,945). An exploratory factor analysis with a randomly chosen subsample supported a 3-factor structure closely corresponding to the 3 BSI-18 subscales: Depression, Anxiety, and Somatization. Confirmatory factor analysis with structural equation modeling validated this 3-dimensional structure in a separate subsample, though an alternative 4-factor model also fit the data. Analysis of the 3-factor model showed consistent fit in male and female participants. Compared with available community-based norms, survivors reported fewer symptoms of psychological distress. Together, results support the hypothesized 3-dimensional structure of the BSI-18 and indicate the measure may be useful in assessing psychological distress in this growing population of cancer survivors.

Forty years on: Teachers' assessments of children's personality traits predict self-reported health behaviors and outcomes at midlife.

A life span health-behavior model was investigated in this longitudinal study of personality influences on health. Teachers assessed 963 elementary schoolchildren on traits that formed scales assessing the dimensions of the five-factor (Big Five) model of personality. Smoking, alcohol use, body mass index (BMI), and self-rated health were assessed 40 years later in midlife. Childhood personality traits were significantly associated with all 4 outcomes, and the effects were consistently larger for women than men. For men and women, childhood Conscientiousness was associated with less adult smoking and better adult self-rated health and, for women only, with lower adult BMI. Mediation analyses suggested that the effects of Conscientiousness on self-rated health were partially mediated by smoking and BMI. These findings add to the growing evidence that childhood personality traits predict adult health outcomes and are discussed in terms of future testing of the life span health-behavior model.

Review of Counseling adults in transition: Linking practice with theory.

Reviews the book, Counseling adults in transition: Linking practice with theory by Nancy K. Schlossberg (1984). Rehabilitation psychologists can profit from this book because of its concise contents, its intensive examination of life's transitions, its gerontological perspectives, its insistent "linking" of otherwise linear thinking, and its pervasive implications for work with rehabilitation clients. This statement of the book's value for our field is given to start with, since its title might suggest that it is relevant only to rehabilitation counseling. Schlossberg ably discusses theories and practices of interest to rehabilitation psychologists and reviews research with pertinent heuristic possibilities.

Sex Steroids and the Shaping of the Peripubertal Brain: The Sexual-Dimorphic Set-Up of Adult Neurogenesis

Steroid hormones represent an amazing class of molecules that play pleiotropic roles in vertebrates. In mammals, during postnatal development, sex steroids significantly influence the organization of sexually dimorphic neural circuits underlying behaviors critical for survival, such as the reproductive one. During the last decades, multiple studies have shown that many cortical and subcortical brain regions undergo sex steroid-dependent structural organization around puberty, a critical stage of life characterized by high sensitivity to external stimuli and a profound structural and functional remodeling of the organism. Here, we first give an overview of current data on how sex steroids shape the peripubertal brain by regulating neuroplasticity mechanisms. Then, we focus on adult neurogenesis, a striking form of persistent structural plasticity involved in the control of social behaviors and regulated by a fine-tuned integration of external and internal cues. We discuss recent data supporting that the sex steroid-dependent peripubertal organization of neural circuits involves a sexually dimorphic set-up of adult neurogenesis that in turn could be relevant for sex-specific reproductive behaviors.     

青海牦犊牛肉脂肪酸组成分析

分析青海牦犊牛与成年牦牛肌肉脂肪酸组成特点,将肌肉提取脂肪后进行甲酯化,以脂肪酸酯标样作为标准品,采用气相色谱仪对试样的脂肪酸甲酯进行定性与定量。结果显示,牦犊牛的MUFA、PUFA相对含量极显著高于成年牦牛（P<0·01）,分别占到总量的32·38%和11·59%,其中油酸、亚油酸含量尤为突出,分别为29·52%、5·72%,而SFA相对含量为53·54%显著低于成年牦牛的61·04%（P<0·05）。牦犊牛PUFA/SFA与n-6/n-3值分别为0·98%、0·22%均极显著高于成年牦牛（P<0·01）。青海牦犊牛肉脂肪酸营养价值更高、更均衡,对牦犊牛的选育、肉品深加工具有一定意义。      

Bifidobacterium bifidum YIT 10347 fermented milk exerts beneficial effects on gastrointestinal discomfort and symptoms in healthy adults: A double-blind,randomized, placebo-controlled study

In a preliminary open-label trial by our group, Bifidobacterium bifidum YIT 10347 (YIT10347) relieved gastric symptoms in patients with functional gastrointestinal disorders. Hence, in this study, we investigated the effects of YIT10347 on gastrointestinal symptoms in healthy adults. In this prospective double-blind, randomized, placebo-controlled trial (UMIN000024654), 100 healthy Japanese adults were randomly assigned to a YIT10347 group or placebo group and consumed 100 mL of YIT10347-fermented milk or placebo fermented milk, respectively, every day for 4 wk. Gastrointestinal symptoms were evaluated by using the modified Frequency Scale for Symptoms of Gastroesophageal Reflux Disease (m-FSSG) and Gastrointestinal Symptom Rating Scale (GSRS) as primary endpoints. Mental symptoms, quality of life, salivary stress markers, and gastric emptying were evaluated as secondary endpoints. Effectiveness and safety were analyzed in a per-protocol set (YIT10347 group, n = 39; placebo group, n = 40) and full analysis set (YIT10347 group, n = 50; placebo group, n = 50), respectively. In the m-FSSG evaluation, the YIT10347 group had a significantly higher relief rate of postprandial discomfort and greater changes in postprandial epigastric pain score from baseline than the placebo group. In the GSRS evaluation, the YIT10347 group had significantly higher relief rates of overall gastrointestinal symptoms, upper gastrointestinal symptoms, flatus, and diarrhea than the placebo group. We detected no significant differences in scores or relief rates of mental symptoms and quality of life, a salivary stress marker, or gastric emptying between the 2 groups. No severe adverse events associated with test beverage consumption were observed in either group. These findings suggest that daily consumption of YIT10347-fermented milk exerts beneficial effects on gastrointestinal discomfort and symptoms such as postprandial discomfort and epigastric pain in healthy adults.
