Pain is a complex sensation influenced by many psychological, relational and socialfactors. Perception and / or painful expression may be wrong in the case of certain chronic diseases such as schizophrenia. In this work we report the cases of two patients with schizophrenia who presented during their hospitalization, abnormal reactivity to pain, to better approach the sensitivity to pain during...

Titania films were grown on BaTiO3 (BTO) substrates by pulsed laser deposition to create (001)Anatase||(100)BTO, (100)Rutile||(111)BTO, and (110)Rutile||(110)BTO heterostructures. The photochemical reactivity was evaluated by observing the amount of silver reduced by each film under identical conditions. The thickest films (100 nm) had reactivities that varied with the phase of titania and the ...

Cue reactivity and craving can be influenced by cue exposure with response prevention (CERP). This study investigated the neural correlates of CERP using functional magnetic resonance imaging, while participants smelled chocolate (17 participants) or a control object (17 participants). CERP was interrupted by 7 scanning sequences measuring the brain response to neutral and chocolate pictures. C...

INTRODUCTION With the progression of substance dependence, drug cue-related brain activation is thought to shift from motivational towards habit pathways. However, a direct association between cue-induced brain activation and dependence duration has not yet been shown. We therefore examined the relationship between alcohol cue-reactivity in the brain, cue-induced subjective craving and alcohol ...

Psychosocial resources have been tied to lower psychological and biological responses to stress. The present research replicated this relationship and extended it by examining how differences in dispositional reactivity of certain neural structures may underlie this relationship. Two hypotheses were examined: (a) psychosocial resources are tied to decreased sensitivity to threat and/or (b) psyc...

It was found that, for a dissolving pulp, an enzymatic pre-treatment with an endoglucanase prior to viscose preparation did not change the correlation between the gamma number of the viscose dope and the carbon disulphide charge. Thus, the pulp stoichiometry, or reactivity, was not changed by an endoglucanase pre-treatment. It has nevertheless previously been found that the pulp reactivity, mea...

The robustness of animal behavior is unmatched by current machines, which often falter when exposed to unforeseen conditions. While animals are notably reactive to changes in their environment, machines often follow finely-tuned yet inflexible plans. Thus instead of the traditional approach of training such machines over many different unpredictable scenarios in detailed simulations (which is t...

been arranged so as to present their results in the context of a general review and presentation of the current status of each particular subject. For this reason, this book should be useful not only to the specialist, but also to those who are entering this field. The book first considers the nature and biochemistry of lymphocyte activating agents and then presents the current status of the kn...

Coal is a prime energy source in India and will continue to play its role for coming several decades. However, our indigenous coal suffers from high ash content and present coal based conventional power generation technologies have several drawbacks such as, lower efficiency, environmental loading and damages thereof. Herein the importance of gasification lies because coal gasification is a mea...

Wright, J .C. and Nesselrote, M.S., 1987. Classification of behavior problems in dogs: distributions of age, breed, sex and reproductive status. Appl. Anim. Behav. Sci., 19: 169-178. One hundred and seventy behavior problems were observed in 105 dogs referred for behaviorproblem management by practicing veterinarians. Ninety percent of the observed behavior problems were classified within three...
