Change of body balance in dancers during two years training

Celem pracy była ocena równowagi ciała osób uprawiających taniec po dwóch latach treningu. W badaniach uczestniczyło 16 tancerzy zespołu pieśni i tańca Ziemia Bydgoska. W celu oceny równowagi ciała wykonano dwukrotnie dwa testy stabilometryczne (oczy otwarte, oczy zamknięte) na platformie stabilometrycznej Sigma w odstępie dwóch lat. Mierzono zmiany położenia COP (Center of Pressure). Testy z oczami otwartymi i z oczami zamkniętymi wypadły zdecydowanie lepiej w pierwszym pomiarze w porównaniu z pomiarem II wykonanym po dwóch latach. Większe różnice wszystkich parametrów obserwowano w teście oczy otwarte w porównaniu z testem oczy zamknięte po upływie dwóch lat. Na podstawie uzyskanych wyników można stwierdzić, że po dwuletnim cyklu uprawiania tańca zdolności do utrzymania równowagi ciała uległy pogorszeniu. AbstractThe purpose of the study was to evaluate the body balance in persons who practice the dance during two years of training. The study involved 16 dancers of Bydgoszcz's song and dance team. In order to assess body balance, two stabilometric tests (eyes open, eyes closed) were performed on a Sigma stabilometer platform at intervals of two-years. Change of sways of the Centre of Pressure (COP) was measured during 30 second. Tests with open eyes and closed eyes were significantly better in the first measurement compared to the second measurement after two years. More differences were observed in the test eyes open compared to test eyes closed after two years. Based on the obtained results it can be stated that after two years of dance practice the ability to maintain balance of body has deteriorated

Uwagi do komentarza prof. Michała Kokowskiego o badaniach życiorysu Jana Czochralskiego

Remarks on the critical comments regarding the contents of the paper published after the presentation delivered by the biographer of Prof. Jan Czochralski. Unfortunately, Prof. Kokowski used an incorrect historical approach to such a short paper. The remarks are presented in four main points.Odpowiedź biografa prof. Jana Czochralskiego na krytyczne uwagi prof. Michała Kokowskiego dotyczące treści artykułu będącego zasadniczo zapisem referatu. Autor zwraca uwagę na ciągłą zmienność opinii i uwag o życiu i działalności Czochralskiego, wynikającą z ujawnianych stale nowych dokumentów i nowej interpretacji znanych faktów. W tej sytuacji odwoływanie się przez prof. Kokowskiego do starych danych nie jest właściwe. Autor omawia cztery przykłady błędnej interpretacji

Od wazeliny do krzemowej rewolucji: czyli niezwykła historia największego polskiego odkrycia, które zmieniło świat

In August 2016 exactly one hundred years passed from the discovery of the Czochralski method of single crystal pulling, named after Jan Czochralski (1885–1953), the Polish chemist and metallurgist. To celebrate this anniversary, a translation of Czochralski main publication into Polish was published. In the present paper we show the pharmaceutical inspiration which was most likely a source of the discovery of the Czochralski method. We present the evolution of this method up to obtaining huge single crystals of silicon, the fundamental element of contemporary electronics and our civilization.W sierpniu 2016 r. minęło sto lat od odkrycia metody otrzymywania monokryształów nazwanej metodą Czochralskiego od nazwiska twórcy – Jana Czochralskiego (1885–1953). Dla uczczenia tej rocznicy opublikowano tłumaczenie podstawowej publikacji Czochralskiego na język polski. W niniejszej pracy pokazano farmaceutyczną inspirację, która zapewne stanowiła źródło odkrycia metody Czochralskiego. Omówiono rozwój metody aż do otrzymywania ogromnych monokryształów krzemu, podstawowego budulca współczesnej elektroniki i współczesnej cywilizacji

Tamponada serca po plastyce szewskiej klatki piersiowej

Pectus excavatum is the most common type of congenital chest wall abnormality (90%), occurs in an estimated 1 in 300–400 births, with male predominance (male-to-female ratio of 3:1). The exact mechanism involved in this abnormal bone and cartilage overgrowth is not known, and, to date, no known genetic defect is directly responsible for the development of pectus excavatum. Despite the lack of an identifiable genetic marker, the familial occurrence of pectus deformity is reported in 35% of cases. The main aim of the thesis was to present an ill patient, who was surgically treated because of pectum excavatum.Szewska klatka piersiowa to najczęstsza (90%) wrodzona deformacja ściany klatki piersiowej występująca w przypadku1 na 300–400 urodzeń, częściej u osób płci męskiej (proporcja płci męskiej do żeńskiej wynosi 3:1). Dokładny mechanizm powodujący nieprawidłowy wzrost kości i chrząstek nie jest znany. Nie wykryto dotychczas żadnego defektugenetycznego, który mógłby się bezpośrednio wiązać z rozwojem tej deformacji. Mimo braku określonego wskaźnikagenetycznego dane literaturowe wskazują na rodzinne występowanie szewskiej klatki piersiowej w 35% przypadków.Głównym celem niniejszej pracy jest przedstawienie przypadku chorego poddanego leczeniu chirurgicznemu z powoduszewskiej klatki piersiowej

Association of socio-economic and demographic factors with physical activity of males and females aged 20–69 years

Objective To assess the physical activity of working residents of Warsaw aged 20–69 years, as well as to identify the socio-demographic factors associated with their levels of physical activity. Material and Methods The study involved 2,544 working residents of Warsaw aged 20–69 years. The short version of the IPAQ was applied and four physical activity levels (insufficient, sufficient, augmented, high) were distinguished. The relationships between physical activity and gender, age, BMI, education, economic and martial status as well as participation in recreation were determined. Results High levels of physical activity were reached by 8% of respondents, 22% achieved augmented level, 32% were sufficiently and 32% insufficiently active. Out of 2544 studied subjects, 6% declared complete sedentariness. Females were, as compared to males, more frequently (p<0.05) insufficiently active (35.9 vs. 31.9%). In obese and overweight subjects insufficient physical activity predominated (42.9 and 36.2%, respectively) and was significantly more frequent than in subjects with normal BMI (31.0%). Moreover, the subjects living in partner relationships were significantly (p<0.05) more frequently insufficiently active than those staying single (36.3 vs. 30.3%). Respondents who declared regular participation in leisure activities were less frequently insufficiently active (20.0%) and more frequently met the criteria of sufficient (37.6%), augmented (28.0%) or high (14.4%) level of physical activity. No significant effects were found with respect to education of respondents. Conclusions Prophylactic schedules associated with the improvement of physical activity level should be addressed particularly to females, people taking up recreation occasionally or to those not involved in recreation at all, living in partner relationships, youngest (21–30 years), in obese and overweight and in the lowest economic category

Postocclusive hyperemia measured with laser Doppler flowmetry and transcutaneous oxygen tension in the diagnosis of primary Raynaud's phenomenon : a prospective, controlled study

The aim of this study was to measure the sensitivity and specificity of transcutaneous oxygen tension and postocclusive hyperemia testing using laser Doppler flowmetry in patients with primary Raynaud’s phenomenon. One hundred patients and one hundred controls were included in the study. Baseline microvascular blood flow and then time to peak flow following occlusion were measured using laser Doppler flowmetry. Afterwards, the transcutaneous oxygen tension was recorded. The sensitivities of baseline microvascular blood flow, postocclusive time to peak flow, and transcutaneous oxygen tension were 79%, 79%, and 77%, respectively. The postocclusive time peak flow had a superior specificity of 90% and area under the curve of 0.92 as compared to 66% and 0.80 for baseline microvascular flow and 64% and 0.76 for transcutaneous oxygen tension. Time to postocclusive peak blood flow measured by laser Doppler flowmetry is a highly accurate test for differentiating patients with primary Raynaud’s phenomenon from healthy controls

The quality of life of patients with overactive bladder after local injections of botulinum toxin A – a preliminary report

Abstract Objectives: The purpose of this work was to evaluate the quality of life of patients suffering from urge urinary incontinence resistant to anticholinergic therapy treated with intradetrusical injections of 200 U botulinum toxin A. Materials and methods: The study group consisted of 10 female patients who were diagnosed with urge urinary incontinence. Standard King’s questionnaire was used for the assessment of the change in the quality of life after treatment. Questionnaires were filled in by all patients before the treatment and during control visits, 3 months after the injection of botulinum toxin A. Results: Statistically significant improvement in the quality of life for the majority of the domains of King’s questionnaire (except the evaluation of urinary incontinence impact on the general health condition and social relations) was observed in 7 out of 10 patients subjected to botulinum toxin therapy (
