Opis:
In this paper, we developed a transportation model for dietary allocation to reduce the risk of overweight and obesity. Our interest was on macronutrients such as carbohydrate, fat and oil and protein diets. These diets are the chief supplier of calories used by the body to perform its metabolic activities. The maximum cost method was used to determine the optimal calories per week from the intake of high fat diet and we found that the calorie required is 478.8 Kcal and average daily required intake is 68.4 Kcal. Again, the least cost method was used to determine the optimal calories per week from the intake of low carbohydrate diet and we found that the calorie required is 681.7 Kcal and average daily required intake is 97.4 Kcal. Comparing the calories from both diets, we conclude that consumption of diet with high fat produce less calories, and hence should reduce the risk of overweight and obesity compared to the consumption of carbohydrate diet even in low quantity. Since calorie is calorie irrespective of its source, we recommend taking high fat diet than taking low carbohydrate diet to reduce the risk of overweight and obesity. The determined daily calories are the minimum calories required by the body to maintain its metabolic activities, more of it will lead to excess and accumulation in the body which will lead to overweight and obesity.

Opis:
Introduction. Yerba Mate, also called Paraguay tea, is obtained from the dried leaves (approximately 95%) and stems (about 5%) of the evergreen shrub-tree Ilex paraguariensis. Each year, the consumption of yerba mate becomes increasingly popular in North America and Europe. The fashion for Paraguay tea has also reached Poland. During the period 2012 – 2018, as much as an 8-fold increase has been observed in the import of this raw material to our country. Objective. The aim of the study is analysis of the present state of knowledge concerning the health effects of Yerba Mate, based on selected scientific literature. Dicussion. The consumption of yerba mate may exert a beneficial effect on human health and its consumption is recommended in the treatment of obesity and while practicing sports. Nevertheless, it should be remembered that a very high consumption of the tea, especially when very hot, may increase the risk of occurrence of cancer, which has not been unequivocally confirmed by scientific studies to-date. Conclusions. It has been confirmed that this beverage shows a number of beneficial health effects, including: a protective effect on liver cells, stimulation of the central nervous system, anti-inflammatory effect, as well as a positive effect on the cardiovascular system.

Objectives The research purpose was to analyze data concerning chemical incidents in Poland collected in 1999–2009 in terms of health hazards. Material and Methods The data was obtained, using multimodal information technology (IT) system, from chemical incidents reports prepared by rescuers at the scene. The final analysis covered sudden events associated with uncontrolled release of hazardous chemical substances or mixtures, which may potentially lead to human exposure. Releases of unidentified substances where emergency services took action to protect human health or environment were also included. Results The number of analyzed chemical incidents in 1999–2009 was 2930 with more than 200 different substances released. The substances were classified into 13 groups of substances and mixtures posing analogous risks. Most common releases were connected with non-flammable corrosive liquids, including: hydrochloric acid (199 cases), sulfuric(VI) acid (131 cases), sodium and potassium hydroxides (69 cases), ammonia solution (52 cases) and butyric acid (32 cases). The next group were gases hazardous only due to physico-chemical properties, including: extremely flammable propane-butane (249 cases) and methane (79 cases). There was no statistically significant trend associated with the total number of incidents. Only with the number of incidents with flammable corrosive, toxic and/or harmful liquids, the regression analysis revealed a statistically significant downward trend. The number of victims reported was 1997, including 1092 children and 18 fatalities. Conclusions The number of people injured, number of incidents and the high 9th place of Poland in terms of the number of Seveso establishments, and 4 times higher number of hazardous industrial establishments not covered by the Seveso Directive justify the need for systematic analysis of hazards and their proper identification. It is advisable enhance health risk assessment, both qualitative and quantitative, by slight modification of the data collection system so as to enable the determination of released chemical concentration and exposed populations.

Opis:
Wprowadzenie: Alergeny roztoczy mogą łatwo gromadzić się w materacach i na powierzchniach tekstylnych, głównie na pościeli. Zatwierdzone strategie ograniczania narażenia na alergeny roztoczy obejmują stosowanie pokrowców z certyfikowanej tkaniny barierowej. Pokrowce mogą znacząco zwiększyć komfort i bezpieczeństwo nocnego snu oraz zapobiegać występowaniu zaostrzeń alergii atopowych i astmy. Celem pracy była ocena skuteczności blokowania alergenów przez nowo opracowane tkaniny barierowe przeznaczone na pokrowce antyalergiczne. Metody: Tkaniny barierowe z włókien poliestrowo-bawełnianych z jednostronną powłoką polimerową zostały opracowane i wytworzone przez Łukasiewicz-Instytut Włókiennictwa. Skuteczność barierową opracowanych tkanin i kontrolnej tkaniny bawełnianej, przed alergenem kurzu i roztoczy kurzu domowego Der p 1, badano zgodnie z wcześniej opisaną i opatentowaną metodą.[1,2]. W skrócie: próbki kurzu domowego odsysano odkurzaczem przez badane tkaniny, a kurz i alergeny zbierano na filtrach. Po ekstrakcji filtrów oznaczono stężenia alergenu roztoczy Der p 1 komercyjną metodą ELISA. Skuteczność barierową określono jako % przepuszczalności tkanin powlekanych w stosunku do kontrolnej tkaniny bawełnianej. Wyniki: Zbadano łącznie sześć rodzajów tkanin powlekanych i wybrano jedną o najlepszych właściwościach, zapobiegających przenikaniu kurzu i Der p 1. Ten opracowany materiał (nazwany Argo Plus) charakteryzował się wysoką skutecznością barierową wobec alergenu Der p 1 (0,15 % przepuszczalności ) oraz przepuszczalnością pary wodnej i powietrza. Po 20 cyklach prania tkanina Argo Plus zachowała swoją funkcję barierową. Wniosek: Stosując naszą oryginalną metodę badania tkanin barierowych, mogliśmy wybrać materiał włókienniczy o optymalnych właściwościach barierowych, który można wykorzystać do produkcji pokrowców na pościel i materace - barierowych wobec alergernów roztoczy kurzu domowego.
Background: Mite allergens can easily accumulate in mattresses and on textile surfaces, mainly on linen. Approved strategies for reducing exposure to dust mite allergens include the use of covers from certified barrier fabric. Covers may significantly increase the comfort and safety of nighttime sleep and prevent the occurrence of exacerbations of atopic allergies and asthma. The aim of this study was to evaluate the allergen-blocking effectiveness of newly developed barrier fabrics designed for antiallergic covers. Methods: The barrier fabrics made of polyester/cotton woven structure with one-sided polymer coating were developed and manufactured by the Łukasiewicz-Textile Research Institute. Barrier effectiveness of designed fabrics and control cotton woven fabric against dust and house dust mite allergen Der p 1 was tested according to the previously described and patent method.[1,2]. In brief, house dust samples were sucked onto the tested textile material with a vacuum cleaner and the allergen was collected on filters. Following a filter extraction, the mite allergen Der p 1 concentration was determined with commercial ELISA method. Barrier effectiveness was defined as the % of permeability of tested fabrics in relation to control cotton fabric. Results: A total of six fabrics types were tested and the one with the best performance in preventing dust and Der p 1 penetration was chosen. This developed textile material (named Argo Plus) was characterized by a high barrier effectiveness against Der p 1 allergen (0,15 % permeability), but at the same time had sufficient permeability to the air and water vapor. When subjected to 20 washing cycles the Argo Plus fabric retained its barrier function. Conclusion: Using our original method for barrier fabrics testing, we were able to select a textile material with optimal barrier characteristics, which may be used to manufacture mattress covers.
