    The enzymes used in degumming, called phospholipases, specifically act on phospholipids without degrading the oil itself. Degumming using a phospholipase C enzyme allows to meet all market specifications while it increases the oil yield. The aim of this study was to evaluate antioxidant and emulsifier properties of the recovered gum (RG) obtained by enzymatic oil degumming process of crude soybean oil subjected to modifications as deoiling (RG deoiled) or ethanol fractionation (RG soluble and insoluble). RG soluble allowed obtaining more stable O/W emulsions (30:70 w/w) in comparison with those by-products assayed at different concentrations (0.1?1.0%). Also, deoiled soybean lecithin (DSL) andRG deoiled had a similar behavior in relation to the kinetic destabilization (%BS profiles), despite the different degumming processes used to obtain these samples. The study on induction times (Metrohm Rancimat) showed a significant antioxidant effect (p<0.05) against a refined sunflower oil associated with all the by-products analyzed. However, RG soluble and DSL showed a strong effect on the oil stability at high concentrations (1000?2000 ppm). These results showed that the deoiled recovered gum and its derivates obtained by ethanol fractionation are a potential alternative for industrial application as additive.Fil: Cabezas, Dario Marcelino.

    Background. Due to the constant increase in the number of morbidly obese patients, an adequate tool for assessing the functioning and disability of these patients is being sought. The International Classification of Functioning, Disability and Health (IC F) could be that tool. Objectives. The aim of this study is to examine the usefulness of the IC F scale in assessing the functioning of morbidly obese patients in two selected areas in reference to recognized scales. Material and methods . The study group included 76 patients with morbid obesity qualified for bariatric treatment. The ICF was applied to assess the function and limitations of each individual. Two domains of the IC F were selected: Body Functions and Structures and Activities and Participation. The usefulness of the IC F was compared to that of the Barthel and EPQ-R scales. Results . In morbidly obese patients, a correlation between motor functions and IC F and BMI, as well as age, was observed. A significant correlation was observed between BMI and psychomotor control, appropriateness and range of emotions experienced, age and amount of sleep, quality of sleep, memory retrieval and psychomotor functions. Women’s mental functions were significantly worse than those of men. In terms of interpersonal relations, a correlation between BMI and regulating behavior within interactions was observed. Conclusions . The IC F is a useful tool for the study and description of the functioning of patients with morbid obesity. The selected domains are described better than by the previously used Barthel scale. Women with morbid obesity tend to have more impaired mental functioning than morbidly obese men

    Metal oxide multi-nanowire-based chemical gas sensors were manufactured by a fast and simple transfer printing technology. A two-step method employing spray pyrolysis deposition and a thermal annealing process was used for SnO 2 nanowires fabrication. A polydimethylsiloxane stamp was used to transfer the SnO 2 nanowires on two different gas sensing devices&mdash;Si-based substrates and microhotplate-based platform chips. Both contained a metallic inter-digital electrode structure (IDES), on which the SnO 2 nanowires were transferred for realization of multi-NW gas sensor devices. The gas sensor devices show a very high response towards H 2 S down to the 10 ppb range. Furthermore, a good response towards CO has been achieved, where in particular the microhotplate-based devices exhibit almost no cross sensitivity to humidity

    Wprowadzenie i cel pracy. Akty prawne dedykowane dyspozytorom medycznym nie precyzują rodzaju wezwań, do których powinni zadysponować określony typ zespołów ratownictwa medycznego (podstawowy zespół ratownictwa medycznego – ZRM P; specjalistyczny zespół ratownictwa medycznego – ZRM S) lub odmówić wyjazdu. Ze względu na inny zakres medycznych czynności ratunkowych dysponowanie przekłada się na czas i rodzaj udzielonej pomocy. Celem pracy było określenie, czy rodzaj wezwania ma wpływ na decyzję dyspozytora o rodzaju ZRM realizującego dane zlecenie. Materiał i metody. Przeanalizowano 1560 kart medycznych czynności ratunkowych (KMCR) z 2012 r. z grupy „Problemy kardiologiczne” wg Systemu Wspomagającego Dowodzenie (SWD), ZRM S i P stacjonujących w 2 lokalizacjach, w każdej 1 ZRM S i P, w jednej 2 miesiące był dodatkowy ZRM P. Zgłaszane dolegliwości, objawy, schorzenia pogrupowano na kategorie objawowe: ból w klatce piersiowej, zaburzenia rytmu, zmiany ciśnienia tętniczego, zaburzenia świadomości, duszność, inne. Określono, ilu chorych podało 1, 2 lub 3 i więcej powodów wezwania ZRM, przeanalizowano częstość poszczególnych objawów. Wyniki. Wybrane ZRM zrealizowały ogółem 13 715 wyjazdów, podstawowe – 7254, specjalistyczne – 6461. 1560 dotyczyło grupy „Problemy kardiologiczne” (11,4%). 556 wyjazdów (8%) – ZRM P, 1004 (16%) – ZRM S. 784 osoby (50%) zgłosiły 1 dolegliwość, 644 pacjenci (41%) – 2, a 132 chorych (9%) – 3 i więcej powodów wezwania. Zgłoszono 2468 dolegliwości. Do 83% zleceń z 3 dolegliwościami, 67% z dwoma i 59% z jednym zadysponowano ZRM S. Ból w klatce piersiowej zgłosiło 56% chorych ZRM P i 69% – S. W pozostałych kategoriach dysponowanie obu typami ZRM było podobne. Wnioski. Rodzaj wezwania miał wpływ na wybór zadysponowanego ZRM. W schorzeniach o podłożu kardiologicznym, o potencjalnie wieńcowym charakterze oraz do prawdopodobnie cięższego stanu pacjenta – więcej niż 2 objawy – częściej dysponowano ZRM S.Introduction and objective. Legislation concerning medical dispatchers does not specify the type of calls for paramedic or specialist EMS team, and when they can refuse to attend to a patient. Due to other scope of medical emergency operations the dispatching determines the time and type of aid. The objective is to determine whether the type of call has an impact on the dispatcher’s decision about the type of EMS team. Material and methods. Research was carried out on the basis of medical documentation submitted in 2012 by 5 EMS teams of the Kraków Emergency Service located in 2 places in ‘Nowa Huta’, with one basic and one specialist team in each, and in one of these places for 2 month there was an additional basic EMS team. 1,560 medical rescue procedure cards were analyzed and classified to a group ‘cardiologic problems’. Reported ailments, symptoms, diseases were grouped into the categories: chest pain, arrhythmia, high blood pressure, loss of consciousness, shortness of breath, other. Results. Selected EMS teams undertook a total of 13,715 trips: basic – 7,254, specialist – 6,461. A group of 1,560 constituted ‘Cardiac Problems’ (11.4%), 556 (8%) – basic EMS team, 1,004 (16%) – specialist EMS team. 784 patients (50%) reported one ailment, 644 patients (41%)-2 and 132 patients (9%) – 3 or more reasons. There were 2,468 reported ailments. Specialist EMS teams were dispatched for 83% of the dispatch orders with 3 problems, 67% with two and 59% with a single problem. 56% of patients of the basic EMS teams and 69% of the specialist team reported chest pain; in other categories, the dispatching of both types of EMS teams was similar. Conclusions. The type of call influenced the choice of dispatching the EMS team. In the case of disorders on a cardiologic, potentially coronary background, and probably a more severe patient’s condition – more than 2 symptoms – more often, the specialist EMS teams were dispatched

    Multi-nanowire based chemical gas sensors were produced employing a fast and simple transfer printing technology. SnO2 nanowires (NWs) were grown by a specific two-step technology including spray pyrolysis deposition and a thermal annealing process in presence of a Cu-catalyst. Subsequently the SnO2 NWs were print transferred by a polydimethylsiloxane (PDMS) stamp on Si-substrates with gold inter-digital electrode structures (IDES) creating a multi-NW chemical sensing device. The print-transfer technology enables a fast, easy and cheap fabrication of NW-based sensor devices with a good reproducibility. High sensitivity to H2S has been achieved, the performance results are presented in this work

    Impact of Weight Loss Due to Sleeve Gastrectomy on Shear Stress of the Femoral Vein in Morbid Obesity

    BACKGROUND: Studies have shown that obesity is associated with venous flow disturbances that lead to changes of the biomechanical forces on the venous wall known as shear stress. We hypothesized that weight loss due to bariatric surgery affects the venous hemodynamics and biomechanical forces on the venous wall. The aim of this study was to evaluate the effects of laparoscopic sleeve gastrectomy (LSG) on the wall shear stress (WSS) and the venous hemodynamics of the femoral vein. METHODS: We studied ten morbidly obese patients who underwent LSG. We investigated venous hemodynamics before, 6 and 12 months after LSG. The femoral vein diameter, cross-sectional area, peak (PeakV) and maximum (TA(max)) velocities, WSS, and shear rate (SR) were assessed. RESULTS: PeakV and TA(max) were significantly lower in the obese patients compared with the control group. WSS and SR were significantly lower in the obese patients compared with the control subjects. Venous hemodynamic parameters increased in the postoperative period at baseline compared with 12 months after surgery: PeakV increased from 17.53 (14.25–20.01) cm/s to 25.1 (20.9–30.1) cm/s (P = 0.04) and the TA(max) from 12.97 (11.51–14.6) cm/s to 18.46 (13.24–24.13) cm/s (P = 0.057). WSS significantly increased from 0.21 (0.19–0.23) Pa at baseline to 0.31 (0.23–0.52) Pa 12 months after surgery (P = 0.031). SR also significantly increased from 47.92 (43.93–58.55) s(−1) at baseline to 76.81 (54.04–109.5) s(−1) 12 months after surgery (P = 0.02). CONCLUSIONS: This study showed that weight loss due to LSG significantly changes the biomechanical forces on the femoral vein generated by blood flow
