( Katarzyna Janiszewska ),( Katarzyna Eufemia Przybylowicz ) 국제태권도학회 2017 Journal of the International Association for Taekw Vol.4 No.1

Purpose: Taekwondo athletes combine different weight loss techniques to compete at the lowest possible weight class. The aim of this study was to determine effective pre-competition weight loss models and to evaluate the risk of negative consequences of using these models. Methods: This study was conducted among 281 athletes. The pre-competition weight loss process was evaluated with validated questionnaire. The weight loss models were determined by non-hierarchical k-means cluster analysis. The risk of negative consequences was evaluated using various methods: anthropometric measurements for evaluation of body size and composition, dual energy X-ray absorptiometry for bone tissue status evaluation, and interviews for description of fettle before competition. Results: A majority of the players (80%) practiced pre-competition weight loss during their ca-reer. Three weight loss models were identified: “active” or increased physical activity combined with food intake reduction was used by 47% of weight-reducing competitors (WRC), “passive” or food intake reduction without increasing physical activity was used by 31% of WRC, and “de-hydration” or a combination of food and fluids intake reduction and exercising in impermeable clothing used by the remaining 22%. Competitors from the dehydration model felt reduced phys-ical capacity, fatigue and decreased immunity more often than competitors from other models. Risk of serious dehydration was the lowest in the “active” models, while it was significantly lower in the “passive” and “active” models than in the “dehydration” model. Conclusions: The study was the first to describe models of the existing combinations of different pre-competition weight loss techniques. It provides important information about the need of iden-tify of athletes using the “dehydration” model because of the high risk of negative consequences. The weight regulation process can be dangerous to athletes` health or even potential for loss of life.

Purpose: Taekwondo athletes combine different weight loss techniques to compete at the lowest possible weight class. The aim of this study was thus to determine effective pre-competition weight loss models and to evaluate the risk of negative consequences of using these models. Methods: This study was conducted among 281 athletes. The pre-competition weight loss process was evaluated with validated questionnaire. The weight loss models were determined by non-hierarchical k-means cluster analysis. The risk of negative consequences was evaluated using various methods: anthropometric measurements for evaluation of body size and composition, dual energy X-ray absorptiometry for bone tissue status evaluation, and interviews for description of fettle before competition. Results: A majority of the players (80%) practiced pre-competition weight loss during their career. Three weight loss models were identified: “active” or increased physical activity combined with food intake reduction was used by 47% of weight-reducing competitors (WRC), “passive” or food intake reduction without increasing physical activity was used by 31% of WRC, and “dehydration” or a combination of food and fluids intake reduction and exercising in impermeable clothing was used by 22% of WRC. Competitors from the dehydration model significantly felt reduced physical capacity, fatigue and decreased immunity more often than competitors from other models. Risk of serious dehydration was the lowest in the “active” models, while it was significantly lower in the “passive” and “active” models than in the “dehydration” model. Conclusions: The study was the first to describe models of the existing combinations of dif-ferent pre-competition weight loss techniques. It provides important information about the need of identification of athletes using the “dehydration” model because of the high risk of negative consequences. The weight regulation process can be dangerous to athletes’ health or even potential for loss of life.

The objective of this study was to obtain the in vitro cultures of Boletus badius under controlled conditions and investigate the release of indole compounds and zinc from the mycelium of B. badius to artificial digestive juices under conditions similar to those in the human gastrointestinal tract. Biomass was obtained from cultures grown using both only the Oddoux medium as well as the same medium with added zinc hydroaspartate and zinc sulfate. The release of 5-hydroxy-L-tryptophan, L-tryptophan, and serotonin from the B. badius biomass extracts to the artificial digestive juices was determined. Differential pulse anodic stripping voltammetry was used to demonstrate that zinc is released from each of the extracted materials. The total amount of zinc in the materials under study was estimated to be between 7.12 and 44.15 mg/100 g dry weight. It was demonstrated that in vitro cultures of B. badius grown using appropriately selected media may supplement zinc and indole compounds.

Ropka-Molik, Katarzyna,Bereta, Anna,Zukowski, Kacper,Tyra, Miroslaw,Piorkowska, Katarzyna,Zak, Grzegorz,Oczkowicz, Maria Asian Australasian Association of Animal Productio 2018 Animal Bioscience Vol.31 No.10

Objective: The aim of the present study was to identify genetic variants based on RNA-seq data, obtained via transcriptome sequencing of muscle tissue of pigs differing in muscle histological structure, and to verify the variants' effect on histological microstructure and production traits in a larger pig population. Methods: RNA-seq data was used to identify the panel of single nucleotide polymorphisms (SNPs) significantly related with percentage and diameter of each fiber type (I, IIA, IIB). Detected polymorphisms were mapped to quantitative trait loci (QTLs) regions. Next, the association study was performed on 944 animals representing five breeds (Landrace, Large White, Pietrain, Duroc, and native Puławska breed) in order to evaluate the relationship of selected SNPs and histological characteristics, meat quality and carcasses traits. Results: Mapping of detected genetic variants to QTL regions showed that chromosome 14 was the most overrepresented with the identification of four QTLs related to percentage of fiber types I and IIA. The association study performed on a 293 longissimus muscle samples confirmed a significant positive effect of transforming acidic coiled-coil-containing protein 2 (TACC2) polymorphisms on fiber diameter, while SNP within forkhead box O1 (FOXO1) locus was associated with decrease of diameter of fiber types IIA and IIB. Moreover, subsequent general linear model analysis showed significant relationship of FOXO1, delta 4-desaturase, sphingolipid 1 (DEGS1), and troponin T2 (TNNT2) genes with loin 'eye' area, FOXO1 with loin weight, as well as FOXO1 and TACC2 with lean meat percentage. Furthermore, the intramuscular fat content was positively associated (p<0.01) with occurrence of polymorphisms within DEGS1, TNNT2 genes and negatively with occurrence of TACC2 polymorphism. Conclusion: This study's results indicate that the SNP calling analysis based on RNA-seq data can be used to search candidate genes and establish the genetic basis of phenotypic traits. The presented results can be used for future studies evaluating the use of selected SNPs as genetic markers related to muscle histological profile and production traits in pig breeding.

Albumin adsorption influence on the stability of the mesoporous zirconia suspension

Katarzyna Szewczuk-Karpisz,Małgorzata Wis´niewska,Dawid Mys´liwiec 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.32 No.-

In this paper, the stability mechanism of the mesoporous zirconia suspension in the albumin presencewas described. The albumin adsorption on the zirconia surface depends on pH and ionic strength. Thehighest adsorption was observed at the albumin pI value (for HSA 3.1 mg/m2). The protein adsorptionaffects the suspension stability. It causes mainly its increase related to electrosteric stabilizationphenomenon (pH 3, 6 and 9). At pH 4.6 there is the system destabilization due to the adsorption of themacromolecules with zero net charge. Under these conditions the greatest stability change was alsoobserved (TSI from 8.38 to 23.97).

Objective: The aim of this study was to develop and validate a questionnaire used to assess the level of general knowledge about cervical cancer, its primary and secondary prevention, and to identify sources of information about the disease among schoolgirls and female students. Methods: The questionnaire development process was divided into four phases: generation of issues; construction of a provisional questionnaire; testing of the provisional questionnaire for acceptability and relevance; field-testing, which aimed at ensuring reliability and validity of the questionnaire. Field-testing included 305 respondents of high school female Caucasian students, who filled out the final version of the questionnaire. Results: After phase 1, a list of 65 issues concerning knowledge about cervical cancer and its prevention was generated. Of 305, 155 were schoolgirls (mean age±SD, 17.8±0.5) and 150 were female students (mean age±SD, 21.7±1.8). The Cronbach alpha coefficient for the whole questionnaire was 0.71 (range for specific questionnaire sections, 0.60 to 0.81). Test-retest reliability ranged from 0.89 to 0.94. Conclusion: The Cervical-Cancer-Knowledge-Prevention-64 has been successfully developed to measure the level of knowledge about cervical cancer. The results confirm the validity, reliability and applicability of the created questionnaire.

Stability mechanism of the silica suspension in the Sinorhizobium meliloti 1021 exopolysaccharide presence

Katarzyna Szewczuk-Karpisz,Małgorzata Wisniewska,Małgorzata Pac-Sosin´ ska,Adam Choma,Iwona Komaniecka 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.35 No.-

This paper describes the electrokinetic, adsorption and stability properties of the silica–exopolysac-charide Sinorhizobium meliloti (EPS). Exopolysaccharide adsorbs on the silica surface in the whole pHrange, but the adsorption amount increases with the pH growth (at pH 9 approx. 0.8 mg/m2). The EPSadsorption affects the electrokinetic and stability properties of the system. At low pH values (3 and 4.6)the increase in the system stability occurs (electrosteric interactions), whereas at higher (7.6 and 9) thelight system destabilization was noted (formation of a single polymer bridges between particles).
