Three alternative views regarding how Major Depressive Disorder (MDD) alters emotional reactivity have been featured in the literature: positive attenuation (reduced positive reactivity), negative potentiation (increased negative reactivity), and emotion context insensitivity (ECI; reduced positive and negative reactivity). Although empirical studies have accumulated on emotional reactivity in ...

The reactivity hypothesis implicates exaggerated cardiovascular reactions to acute psychological stress in the development of hypertension and other cardiovascular disease outcomes. However, cardiovascular reactivity has also been suggested as a mediator between a variety of psychosocial and behavioural risk factors and cardiovascular disease. Data from various analyses of the West of Scotland ...

intradermal injection of autologous serum and plasma elicit a cutaneous reactivity in almost 45-60% of patients with chronic idiopathic urticaria (ciu).   this reactivity is associated with the presence of auto antibodies against ige or ige receptors. this study was carried out to compare the cutaneous reactivity of autologous serum and plasma skin tests in a series of patients with ciu for dia...

Elevated neuroticism is associated with increased psychological reactivity to stressors. Research on individual differences and physiological reactivity (e.g., electrodermal activity), however, has focused on clinical samples and measures of basal activity (e.g., nonspecific skin conductance responses) or responses to nonaffective stimuli. Surprisingly, there is a dearth of work on physiologica...

BACKGROUND The classic view of blood pressure (BP) reactivity to psychological stress in relation to cardiovascular risks assumes that excess reactivity is worse and lower reactivity is better. Evidence addressing how stress-induced BP reactivity in young adults is associated with midlife cognitive function is sparse. METHODS AND RESULTS We assessed BP reactivity during a star tracing task an...

A new methodology to obtain reactivity indices has been defined. This is based on reactivity functions such as the Fukui function or the dual descriptor and makes it possible to project the information of reactivity functions over molecular orbitals instead of the atoms of the molecule (atomic reactivity indices). The methodology focuses on the molecule's natural bond orbitals (bond reactivity ...

A subset of schizophrenic patients has demonstrated increased language dysfunction in affectively stressful, compared to non-stressful conditions. Affective reactivity of right-ear advantage has been demonstrated in studies of dichotic listening in schizophrenia. The present study assessed whether participants who showed affective reactivity of speech were also those who showed affective reacti...

altered glycosylation of proteins in cancer cells is one of the main processes responsible for anaplasia, invasion and metastatic potential of neoplastic cells. lectins are nonimmunogenetic compounds which specifically detect certain terminal sugars of glycoconjugates. the aim of the present study was to identify the n-acetylgalactosamine (galnac) containing glycoconjugates in cancer cells in a...
