In humans, anticipatory stress involves activation of the limbic-hypothalamic-pituitary-adrenal axis, which releases stress hormones such as cortisol in response to an impending stressor. Conditioning of the stress response to anticipate and prepare for future challenges is a hallmark of adaptation. It is unknown whether human infants in the first year of life have developed the neural circuitr...

Exposure of animals to footshocks (FS) in absence of any specific cue results in the development of fear to the compartment where shocks were given (contextual fear conditioning), and this is usually evaluated by time spent freezing. However, the extent to which contextual fear conditioning always develops when animals are exposed to other stressors is not known. In the present work we firstly ...

Development of antiviral resistance is a particular concern for the Advisory Committee on Antimicrobial Resistance and Healthcare-Associated Infections (ARHAI). Over the last 4 years, considerable time has been devoted to examining the ability of the UK to monitor the presence and transmission of antiviral resistance. Resistances to antiviral agents in influenza virus, HIV and hepatitis B and C...

The purpose of this study was to identify whether cortisol reactivity to a stressful laboratory event was related to children's memory of that event and to determine whether this relation was comparable to that observed in adults. Nine- to 12-year-olds and young adults completed an impromptu speech and math task during which repeated cortisol samples and self-reported stress ratings were collec...

Stress influences health and disease and this might be of special relevance for ageing. The present review starts with the description of age-associated changes of the hypothalamic-pituitary-adrenal axis. In this context, the possible modulatory role of estradiol is discussed. Later, the influence of rising stress hormone levels for the ageing brain is illustrated and a few intervention strateg...

BACKGROUND AND OBJECTIVE Hypothalamic-pituitary-adrenal axis suppression (HPAS) when treating children with corticosteroids is thought to be rare. Our objective was to determine the prevalence of and predictive factors for various degrees of HPAS. METHODS Clinical features of HPAS, doses, adherence, asthma score, and lung functions were recorded in 143 asthmatic children. The overnight metyra...

Well-characterized antibodies are essential tools for protein studies, global proteomics analysis, as well as for clinical diagnostics. However, although production of antibodies is a well-established process and a large number of antibodies are commercially available through many vendors, specific antibodies still do not exist for the majority of human proteins. An underlying factor limiting t...

BACKGROUND Lack of social support and social exclusion are associated with adverse effects for mental and physical health. Additionally, women appear to be more vulnerable to social triggers of health disturbances. Activity of the hypothalamus-pituitary-adrenal-axis (HPA-axis) might play a key role in this context as it has been shown both to be associated with psychosocial conditions and healt...
