BACKGROUND/OBJECTIVES the association between late-life obesity and late-life cognitive abilities is poorly understood. We studied the association between body mass index (BMI) and cognitive change in longitudinal population-based study spanning over the ninth decade of life. SUBJECTS/METHODS in total, 475 participants free of dementia at baseline from the Lothian Birth Cohort 1921 (mean age:...

labor is a physiological event involving a sequential, integrated set of changes within the myometrium, deciduas, and uterine cervix that occur gradually over a period of days to weeks. biochemical connective tissue changes in the uterine cervix appear to precede uterine contractions and cervical dilation, and all of these events usually occur before rupture of the fetal membranes. in other wor...

Predator presence causes acute stress in mammals. A prey animal's stress response increases its chance of survival during life-threatening situations through adaptive changes in behavior and physiology. Some components of the physiological stress response can lead to changes in body surface temperatures. Body temperature changes in prey could provide information about prey state to predators th...

introduction: natural process of aging is associated with biological events which alter the structure and function of different parts of the body. larynx also undergoes age-related anatomical and physiological changes during adulthood.. according to anatomical and physiological changes of larynx, acoustic and perceptual characteristics of voice are modified as a result of age-related sequential...

By integrating behavioral measures and imaging data, previous investigations have explored the relationship between biological markers of aging and cognitive functions. Evidence from functional and structural neuroimaging has revealed that hippocampal volume and activation patterns in the medial temporal lobe (MTL) may predict cognitive performance in old age. Most past demonstrations of age-re...

INTRODUCTION A number of reports have identified significant personality differences in patients with Parkinson's disease (PD) when compared with age-matched controls. We hypothesised that these differences may be related to impairment in prefrontal inhibitory functions resulting in the expression of new "Machiavellian" personality traits. METHODS Thirty-five patients with PD and 17 age-match...
