Suicides committed under the alcohol constitute on average 20% of all suicidal deaths. Alcohol is a signifant factor of suicidal risk. The assessment of the role of alcohol in the decision to commit suicide is in many cases difficult. Only in the case of the suicidal death of an alcoholic the circumstances of the influence of alcohol on self-destructive behavior is not as important, unless it is a means to "get rid" of alcoholism. As rule alcohol is drunk to gain courage — to make the decision to commit suicide easier.

The study deals with the dependencies between indicators characterising the colored matter in cherry wines as well as three technological parameters: pH, sulfur dioxide, and alcohol. The experiment has been established in accordance with the CCRD system (Central Composite Rotatable Design) considering each of three independent variables at five different levels. Second-order polynomial equation has been fitted to each qualitative trait. It has been found that fitted models – at 0.01 level – have sufficiently described the variability of the studied wine colour indices (WC), polymeric pigment colour (PPC), anthocyanin colour (AC), colour quality (T), and chemical age of wine (CAW). Determination coefficients R2 for those traits have been higher than 0.55, therefore the variability of each trait has been in over 55% explained by the fitted model. Fitted regression models can be used to predict studied indicators characterising the colored matter at wines.

Natural sweeteners in a human diet

84%
Sweeteners, both natural and artificial, play an important role in a human diet as well as are of great importance to the food industry and dieticians. Many people associate sweet taste with sucrose, which is commonly known as table sugar. However, there are many sweet substances that food manufacturers add to food products because none of them is ideal for all applications. Besides sucrose there are also other sugars such as glucose and fructose that originate both from natural sources such as fruits and honey or from added sugars. Among sweeteners there are also compounds which have a sweet taste and contain no calories or those which sweetness is so intense so can be used at very low concentrations, thus, their impact on the total caloric value of the product is negligible. They can be classified due to their origin (natural or synthetic agents), the technological function (sweeteners and fillers), texture (powders and syrups), and nutritional value (caloric and non-caloric). Natural sweetening substances include carbohydrates, sugar alcohols, thaumatin and stevia. Besides providing well tasting foods, they might have an impact on products’ texture, color, preservation and caloric value. Sugar alcohols, which belong to carbohydrates, are both natural sugar substitutes and food additives. They are becoming more and more popular among consumers mainly due to their lower caloric values and glycemic indexes as well as anticariogenic effects. Sugar alcohols are often combined with other sweeteners to enhance food products’ sweetness. Stevia, which is 200 times sweeter than sucrose, is a non caloric substance whereas thaumatin, a sweet protein, provides 4 kcal/g but characterizes with sweetness about 2000 times higher than sucrose (on a weight basis).
This study investigated the effects of systemic alcohol injections on respiratory activity and short-term potentiation (STP) of the phrenic nerve and hypoglossal nerve activities, evoked by electrical stimulation of the superior laryngeal nerve (SLN), in anesthetized, paralyzed, and artificially ventilated rabbits. Alcohol, in a dose of 500 mg/kg, given singly or in cumulative fractions of 100mg/kg, depressed hypoglossal activity with little or no effect on phrenic activity. SLN stimulation inhibited both phrenic and hypoglossal activities and this effect remained unchanged by either way of alcohol administration. After cessation of stimulation, hypoglossal activity increased above the control level and slowly declined to the baseline, showing signs of STP. The amplitude and duration of the hypoglossal STP decreased following a single dose of alcohol. Cumulative fractions of the alcohol dose evoked a biphasic effect on the respiratory STP. In a lower range, alcohol enhanced the hypoglossal STP and tended to increase the duration of the phrenic STP. This effect gradually declined with increasing cumulative dose of alcohol and finally reversed to the inhibition of the STP of both nerves. The results demonstrate a dose-dependent biphasic effect of alcohol on the induction and maintaining of the hypoglossal STP. A reduction in STP, together with hypoglossal activity depression following alcohol accumulation, may contribute to the facilitation of upper airway obstruction by alcohol.
Background. The transition from high school to college is an important milestone in the life of adolescents. In this stage of life, they are already aware of their responsibility for their health, which allows them to develop their health habits. The aim of this study was to increase the knowledge about selected aspects of female university students’ lifestyle, including sports, sleep, stress, alcohol and smoking. Material and methods. This cross-sectional research was carried out with 1,055 female university students in their first year of study at two universities in Slovakia as part of the VEGA grant project no. 1/0825/17 “Recommendations for physical activities in prevention and control of non-communicable diseases and their implementation in the Eastern part of Slovakia” implemented at P.J. Šafárik University in Košice. Data was collected on lifestyle factors, including frequency and regularity of participating in sports during the preceding half year, by means of a questionnaire. Results. Students of both universities reported low levels of engagement in sport activity in the preceding six months, in terms of frequency and regularity of its weekly performance. There appeared to be a statistically significant relationship between the frequency of sport activity and fatigue after waking. Other relationships were not found to be statistically significant. Conclusions. The scope of educational work by university education experts should include appropriate ways of influencing the lifestyle of first-year university students towards maintaining their good health. This can be carried out within the context of health education during compulsory and optional physical education classes.
