Calorie Restriction and Aging in Humans

Calorie restriction (CR), the reduction of dietary intake below energy requirements while maintaining optimal nutrition, is the only known nutritional intervention with the potential to attenuate aging. Evidence from observational, preclinical, and clinical trials suggests the ability to increase life span by 1-5 years with an improvement in health span and quality of life. CR moderates intrinsic processes of aging through cellular and metabolic adaptations and reducing risk for the development of many cardiometabolic diseases. Yet, implementation of CR may require unique considerations for the elderly and other specific populations. The objectives of this review are to summarize the evidence for CR to modify primary and secondary aging; present caveats for implementation in special populations; describe newer, alternative approaches that have comparative effectiveness and fewer deleterious effects; and provide thoughts on the future of this important field of study

Assessing deictic relational responding in social anxiety using the Implicit Relational Assessment Procedure

The current study sought to investigate perspective-taking in a group of individuals diagnosed with psychosis. The Social Anxiety Implicit Relational Assessment Procedure (SA-IRAP) contrasted statements and questions referring to 'anxious' and 'non-anxious' experiences. The SA-IRAP and a Faux-pas (Theory of Mind) test were presented to two groups of participants: a clinical group with a diagnosis of social anxiety and a group of controls. IRAP effects for each group were in the predicted direction and a ROC analysis showed that the IRAP correctly classified 77% of the individuals with social anxiety with a sensitivity level of 97% and a specificity level of 36%. The IRAP was thus successfully used to correctly classify the sample of clinical individuals. However, the study also demonstrated that the two groups were similar with regard to their level of competency on the perspective-taking IRAP. The article also discusses the relationship between the data and recent developments in RFT

Efficacy of cypermethrin on the control of Struthiolipeurus spp. (Phthiraptera: Philopteridae) in ostrich Eficácia da cipermetrina no controle de Struthiolipeurus spp. (Phthiraptera: Philopteridae) em avestruz

<abstract language="por">Duzentos e quarenta avestruzes, com idades entre 12 e 24 meses, foram examinados quanto ao parasitismo por Struthiolipeurus spp. Destes, 168 apresentavam-se infestados por piolhos (70%). Todas as aves foram tratadas com solução de cipermetrina a 15%, na diluição de 1ml/l, por pulverização com auxílio de uma bomba costal. Os animais positivos foram reexaminados nos dias 7, 14 e 21 após o tratamento, e não foram mais encontrados piolhos. A cipermetrina apresentou 100% de eficácia no controle de piolhos do gênero Struthiolipeurus em avestruz
