The attention towards the bacteria associated with human health is growing more and more, above all regarding the bacteria that inhabit the niches offered by the human body, i.e., the gastrointestinal tract, skin, vaginal environment, and lungs. Among the secondary metabolites released by microorganisms associated with human health, little consideration is given to the biosurfactants, molecules with both hydrophobic and hydrophilic nature. Their role in the complex human environment is not only the mere biosurfactant function, but they could also control the microbiota through the quorum sensing system and the antimicrobial activity. These functions protect them and, accordingly, the human body principally from microbial and fungal pathogens. Consequently, nowadays, biosurfactants are emerging as promising bioactive molecules due to their very different structures, biological functions, low toxicity, higher biodegradability, and versatility. Therefore, this review provides a comprehensive perspective of biosurfactants with antimicrobial activity produced by bacteria associated with the human body and related to everything human beings are in contact with, e.g., food, beverages, and food-waste dumping sites. For the first time, the role of an “-omic” approach is highlighted to predict gene products for biosurfactant production, and an overview of the available gene sequences is reported. Besides, antimicrobial biosurfactants’ features, challenges, and potential applications in the biomedical, food, and nutraceutical industries are discussed.

Human body parts are sometimes compressed by tight clothes, footwear, bandages etc. Therefore, it is important to balance between functionality and comfort of garments in order to avoid negative effects on human health. Mechanical properties of both garment and tissue need to be taken into account for the analysis of pressure of tight garments. The thick walled tube theory is adjusted to a composite cylinder with a rigid core, as an approximate limb model with corresponding edge conditions. The results suggest the effect of tightness and elastic properties of the tissue and the tight garment on the level and type of tissue stresses.

The European laws and recently the Romanian ones impose more and more strict norms to the large nitrogen dioxide polluters. They are obligated to continuously improve the installations and products so that they limit and reduce the nitrogen dioxide pollution, because it has negative effects on the human health and environment. In this paper are presented these researches made within a case study for the Timi�oara municipality, regarding the modeling and simulation of the nitrogen dioxide dispersion phenomenon coming from various sources in atmosphere with the help of analytical-experimental methods. The mathematical model resulting from these researches is accurately enough to describe the real situation. This was confirmed by comparing the results obtained based on the model with real experimental values.

Background/aim: Use of nanomaterials in the healthcare applications increases in parallel to technological developments. It is frequently utilized in diagnostic procedures, medications and in therapeutic implementations. Nanomaterials take place among key components of medical implants, which might be responsible for certain toxic effects on human health at nano-level. In this review, nanotoxicological effects, toxicity determination of nanobiomaterials used in human body and their effects on human health are discussed. Material and Method: A detailed review of related literature was performed and evaluated as per nanomaterials and medical implants. Results and Conclusion: The nanotoxic effects of the materials applied to human body and the determination of its toxicity are important. Determination of toxicity for each nanomaterial requires a detailed and multifactorial assessment considering the properties of these materials. There are limited studies in the literature regarding the toxic effects of nanomaterials used in medical implants. Although these implants are potentially biocompatible and biodegradable, it is highly important to discuss nanotoxicological characteristics of medical implant.

Excessive Risk

AbstractThe belief that one is in a worse situation than similar others (Relative Deprivation) has been associated with involvement in a range of maladaptive escape behaviors, including excessive risk taking. Yet not everyone scoring high on measures of relative deprivation makes maladaptive choices. We hypothesized that hope may ameliorate the negative effects of relative deprivation. In two laboratory-based experiments using a novel risk-taking task (N = 101) we show that hope reduces risk-taking behavior in relatively deprived participants. A third study (N = 122) extended the moderating effect of hope on relative deprivation to real-world risk behavior; increased hope was associated with decreased likelihood of loss of control of one’s gambling behavior in relatively deprived individuals. Nurturing hope in relatively deprived populations may protect them against maladaptive behaviors with potential applications for harm reduction.

From ancient times, humans are striving for being healthy and to live with mental peace with family and society. In the previous centuries also, some manmade and mostly natural disasters have disturbed the pace of human life. There have been times when the whole human race has been in terror, danger, and utmost worry. The electrical gadgets also have made the human life comfortable, but also machines have dominated its consciousness. The stress, aggression, depression, and many more issues are also showing presence in all our lives. The chapter is a trial to establish the effect of yagna and mantra science over human calmness and its effect on human health irrespective to gender and age. The article also elaborates the effect of Sanskrit sound and mantra chanting on emission of radiations from electronic gadgets. It also presents the effect of spiritual practices on the human body and soul after the terror, stress, grief created due to COVID-19.

State policy in the field of healthy nutrition is a timely and vital, because inadequate nutrition for the physical needs of the body poses a threat to national security today. The article analyzes the state of nutrition of the population of Ukraine in recent years, which is marked by negative trends, both in relation to energy adequacy and in relation to the chemical composition of diets. It is proven that the harm to health is caused by insufficient intake of vitamins, minerals and trace elements, resulting in reduced physical and mental performance, resistance to various diseases, increased negative effects on the body of adverse environmental conditions, harmful production factors, nervous and emotional stress and stress. The purpose of this work is to scientifically substantiate the composition of a fermented milk product enriched with sprouted barley grains and rosehip syrup, which allows improving the structure of the human nutrition through the use of functional ingredients and facilitating the adaptation of the human body to adverse external conditions. Experts associate the positive effect of fermented milk products for the human body with the appearance in them of physiologically active functional components, which are also useful in a physiological form. The value of fermented milk products in functional nutrition is determined primarily by the unique composition of microflora, food and biological value of products. Speaking about the nutritional value of fermented milk products, it is necessary to consider in detail the nutritional substances that make up its composition. In the lifr process of lactic acid bacteria, a complex of biologically active substances (enzymes, lactic and acetic acids, antibiotic substances) is accumulating. Dietary fermented milk products improve metabolism, stimulate the secretion of gastric juice, stimulate the appetite. Improving the health of the human body and ensuring its active life through the use of fermented milk products with functional properties is a new promising direction in medicine and nutrition, as its integral part.
