Study of the opportunities of kinesitherapy to tackle obesity in school-age

Obesity is a disease associated with excessive accumulation of body fat. Obesity in children is not only aesthetic, but also one of the most serious medical and social problems of our time, which is constantly growing. Its great medical and social importance is determined by the fact that it favors the development of many diseases - type 2 diabetes, cardiovascular diseases, diseases of the musculoskeletal system and others. According to the World Health Organization (WHO) Bulgaria ranks fifth in Europe in obese children.Objective: This study examines the possibilities of kinesitherapy as a means to tackle obesity in school age.The study was conducted within three months at the Medical Center for Rehabilitation and Sports Medicine „Prostor` - Varna. It involves 32 children with overweight and obesity between the ages of 7 and 15 years. Before and after the kinesitherapeutic program every child goes through a clinical medical examination including measurements of height and weight, calculation of Body Mass Index (BMI) and laboratory tests.After analyzing the obtained data, we report reduction in weight, depending on to what extent the recommendations for balanced nutrition and physical activity are followed for the rest of the day.Nutrition and physical activity are crucial to the health and prerequisite for ensuring optimal growth and development of children and adolescents.tudy of the opportunities of kinesitherapy to tackle obesity in school-age

The benefits of sports for the physical and mental health of adolescents

A healthy lifestyle is the main expression of positive health behavior. Movement is a natural need of every child and is a basic preventive tool for strengthening children‘s health. Sport is a complex process that improves the qualities of movements, strengthens the muscles of the body and forms physical endurance through its positive influence on all organs and systems. Sports activities have a beneficial effect on the psyche and personality of adolescents and are defined as the main factor for maintaining, preserving and improving health and a healthy lifestyle. In most European countries, the teaching methodology is aimed at finding the meaning and encouraging the desire of each student to engage in regular physical activity. The article aims to familiarize the audience with the impact of sports on various organs and systems, with the benefits for the physical and mental health of adolescents from sports activities, as well as to provide information on recommendations for the correct choice of sports depending on the constitution and disposition of adolescents

NLA-Bit: A Basic Structure for Storing Big Data with Complexity O(1)

This paper introduces a novel approach for storing Resource Description Framework (RDF) data based on the possibilities of Natural Language Addressing (NLA) and on a special NLA basic structure for storing Big Data, called “NLA-bit”, which is aimed to support middle-size or large distributed RDF triple or quadruple stores with time complexity O(1). The main idea of NLA is to use letter codes as coordinates (addresses) for data storing. This avoids indexing and provides high-speed direct access to the data with time complexity O(1). NLA-bit is a structured set of all RDF instances with the same “Subject”. An example based on a document system, where every document is stored as NLA-bit, which contains all data connected to it by metadata links, is discussed. The NLA-bits open up a wide field for research and practical implementations in the field of large databases with dynamic semi-structured data (Big Data). Important advantages of the approach are as follow: (1) The reduction of the amount of occupied memory due to the complete absence of additional indexes, absolute addresses, pointers, and additional files; (2) reduction of processing time due to the complete lack of demand—the data are stored/extracted to/from a direct address

Caputo Fractional Differential Equations with Non-Instantaneous Random Erlang Distributed Impulses

The p-moment exponential stability of non-instantaneous impulsive Caputo fractional differential equations is studied. The impulses occur at random moments and their action continues on finite time intervals with initially given lengths. The time between two consecutive moments of impulses is the Erlang distributed random variable. The study is based on Lyapunov functions. The fractional Dini derivatives are applied

AmyA, an α-Amylase with β-Cyclodextrin-Forming Activity, and AmyB from the Thermoalkaliphilic Organism Anaerobranca gottschalkii: Two α-Amylases Adapted to Their Different Cellular Localizations

Two α-amylase genes from the thermophilic alkaliphile Anaerobranca gottschalkii were cloned, and the corresponding enzymes, AmyA and AmyB, were investigated after purification of the recombinant proteins. Based on their amino acid sequences, AmyA is proposed to be a lipoprotein with extracellular localization and thus is exposed to the alkaline milieu, while AmyB apparently represents a cytoplasmic enzyme. The amino acid sequences of both enzymes bear high similarity to those of GHF13 proteins. The different cellular localizations of AmyA and AmyB are reflected in their physicochemical properties. The alkaline pH optimum (pH 8), as well as the broad pH range, of AmyA activity (more than 50% activity between pH 6 and pH 9.5) mirrors the conditions that are encountered by an extracellular enzyme exposed to the medium of A. gottschalkii, which grows between pH 6 and pH 10.5. AmyB, on the other hand, has a narrow pH range with a slightly acidic pH optimum at 6 to 6.5, which is presumably close to the pH in the cytoplasm. Also, the intracellular AmyB is less tolerant of high temperatures than the extracellular AmyA. While AmyA has a half-life of 48 h at 70°C, AmyB has a half-life of only about 10 min at that temperature, perhaps due to the lack of stabilizing constituents of the cytoplasm. AmyA and AmyB were very similar with respect to their substrate specificity profiles, clearly preferring amylose over amylopectin, pullulan, and glycogen. Both enzymes also hydrolyzed α-, β-, and γ-cyclodextrin. Very interestingly, AmyA, but not AmyB, displayed high transglycosylation activity on maltooligosaccharides and also had significant β-cyclodextrin glycosyltransferase (CGTase) activity. CGTase activity has not been reported for typical α-amylases before. The mechanism of cyclodextrin formation by AmyA is unknown
