Neuropsychiatric manifestations of some tropical diseases.

Some tropical diseases are the direct cause of severe disturbances of cerebral function while others affect only finer cerebral systems controlling fears, anxiety and personality traits. The mechanisms by which psychiatric symptoms are produced in tropical disorders are not any different from the mechanisms that relate to any physical disorders. Neuropsychiatric symptoms may be caused by a number of different mechanisms including bacterial toxins, release of cytokines, hyperthermia, shock (poor perfusion), acute renal insufficiency, pulmonary failure (shock lung), coagulopathy, disruption of the blood-brain barrier, and/or the nest of pathogens into the central nervous system.

The evaluation of stress coping styles and type D personality in patients with coronary artery disease.

Background: The relationship between depression and heart disease is very complex. In the group of patients with depression the coronary artery disease risk factors related to lifestyle (lack of physical activity, smoking, hypertension, and diabetes) are frequently observed. For many years, researchers have been interested in the relationship between personality and the tendency to collapse on somatic disorders.

Personality determinants of health behaviours of merchant navy officers.

Background And Aim: An individual's health behaviours are highly correlated with selected areas of their personality as well as their values, needs and goals. However, this relationship may be modified by a number of objective factors associated with the individual's functioning, lifestyle or occupational activity. The main objective of the presented study was to investigate the relationship between personality profiles and health behaviours of merchant navy officers.

Quantitative Thermodynamic Analyses of Spectroscopic Titration Curves.

Elucidation of ligand - macromolecule interactions requires detailed knowledge of energetics of the formed complexes. Spectroscopic methods are most commonly used in characterizing molecular interactions in solution. The methods do not require large quantities of material and most importantly, do not perturb the studied reactions.

Purpose in life and work-related stress in mariners. Mediating role of quality of marriage bonds and perceived anxiety.

Background: The specific character of mariners' work is connected with many factors conducive to stress, overload, fatigue and emotional tension, all of which can negatively influence subjective quality of life, including particularly the sense of life's purpose and meaning. However, over the course of entire life one plays many various roles and takes part in many areas of life which influence one another, both positively and negatively. Undoubtedly one of such areas, essential from the point of fulfilling individual's important needs, is one's family and marriage that can function as a crucial factor for neutralising on-the-job problems and tensions.

Occupational hazards for fishermen in the workplace in Polish coastal and beach fishing--a point of view.

The work of marine fishermen is considered one of the most dangerous and life-threatening professions all over the world. There are some common features of the fishing occupation, such as: exposure to cold, wind, rough seas, substantial participation of physical effort, frequency of injuries during work, unpredictability and abruptness of threats, equipment failure, everyday psychological stress, and constant economic pressure. At the same time, the specificity and variety of hazards, depending significantly on geographical-climate and cultural factors, makes the dissimilarity of problems and solutions substantial in different sectors of fishing.
