    Plants of the Asteraceae family have been used in traditional medicine for thousands of years. Now, forgotten for some time, they are gaining popularity again. The aim of this study was to determine and compare the proximate composition and antioxidant activity of inflorescences and leaves of Taraxacum officinale F.H. Wigg. (common dandelion), Tanacetum vulgare L. (tansy) and Solidago virgaurea L. (European goldenrod). The content of dry matter, crude protein, crude ash and crude fat was determined according to the Association of Official Analytical Chemists (AOAC). The content of total polyphenols was determined using methanol extracts. Antioxidant activity was determined by three methods. The protein content was the highest in Taraxacum officinale. The fat and ash content increased in the sequence of Solidago virgaurea Tanacetum vulgare Taraxacum officinale. The total content of polyphenols in the material and its antioxidant activity (AA) were different between species. Changes were also observed in the morphological parts of the plants. The results of the research encourage the use of not only those parts of plants known but also inflorescences or leaves, which can be excellent ingredients for drugs and other preparations used in medicine or cosmetology and also in the food industry

    Regular moderate physical activity positively affects health, fitness, and body composition; it regulates the pro- and anti-inflammatory cytokines levels. Vitamin D plays an important regulatory role; its adequate levels correlate with low values of inflammation markers and an increase in muscle strength and fitness in exercising people. The study鈥檚 aim was to evaluate changes in somatic variables, oxidative stress, and inflammation markers, as well as blood calcidiol concentration in middle-aged healthy women after 12 weeks of aerobics classes鈥攅ndurance exercises, including choreographic sequences, aiming to improve fitness and motor coordination. The training led to a significant reduction of body mass and fat tissue; it induced an increase in lean body mass. After the 12-week training program, plasma antioxidant status increased (0.65 卤 0.21, p<0.01) and the concentration of lipid peroxidation products decreased (0.07 卤 0.02, p<0.001). A significant increase in plasma antioxidant status associated with training could have reduced the level of proinflammatory interleukin as indicated by a positive correlation between these variables (rs = 0.64, p<0.05). The study proved that a 12-week health training program in physically inactive middle-aged women might provide improvements in their anthropometric parameters and selected biochemical indicators

    This paper presents an insight into the geology of the area surrounding the ODDP proposed drilling site, and the structural development of the Carpathians in post-Palaeogene times. Since the deep drilling is proposed to be located in the Orava region of the Northern Carpathians, on the Polish-Slovak border, the structure and origin of the Neogene Orava Basin is also addressed in the paper. The outline of geology of the Carpathian Mountains in Slovakia and Poland is presented. This outline includes the Inner Carpathian Tatra Mountains, the Inner Carpathian Palaeogene Basin, the Pieniny Klippen Belt, the Outer Carpathians, the deep structure below the Carpathian overthrust, the Orava Basin Neogene cover, the Neogene magmatism, faults and block rotations within the Inner and Outer Carpathians, and the Carpathian contemporary stress field. The outline of geology is accompanied by the results of the most recent magnetotelluric survey and the detailed description of the post-Palaeogene plate tectonics of the circum-Carpathian region. The oblique collision of the Alcapa terrane with the North European plate led to the development of the accretionary wedge of the Outer Carpathians and foreland basin. The northward movement of the Alpine segment of the Carpathian-Alpine orogen had been stopped due to its collision with the Bohemian Massif. At the same time, the extruded Carpatho/ Pannonian units were pushed to the open space, towards a bay of weak crust filled up by the Outer Carpathian flysch sediments. The separation of the Carpatho/Pannonian segment from the Alpine one and its propagation to the north was related to the development of the N-S dextral strike-slip faults. The formation of the West Carpathian thrusts was completed by the Miocene time. The thrust front was still progressing eastwards in the Eastern Carpathians. The Carpathian loop including the Pieniny Klippen Belt structure was formed. The Neogene evolution of the Carpathians resulted also in the formation of genetically different sedimentary basins. These basins were opened due to lithospheric extension, flexure, and strike-slip related processes. A possible asteno- sphere upwelling may have contributed to the origin of the Orava Basin, which represents a kind of a rift modified by strike-slip/pull-apart processes. In this way, a local extensional regime must have operated on a local scale in the Orava region, within the frame of an overall compressional stress field affecting the entire West Carpathians. Nevertheless, many questions remain open. Without additional direct geological data, which can be achieved only by deep drilling under the Orava Deep Drilling Project, these questions cannot be fully and properly answered.W grudniu 1999 Polska do艂膮czy艂a do programu wierce艅 kontynentalnych - International Continental Scientific Drilling Program (ICDP). W ramach tego programu jest przygotowywany projekt g艂臋bokiego wiercenia w strefie kontaktu teranu Karpat wewn臋trznych i p艂yty p贸艂nocnoeuropejskiej. Praca przedstawia zarys geologii Karpat na terenie Polski i S艂owacji, ze szczeg贸lnym uwzgl臋dnieniem Tatr, paleogenu wewn膮trzkarpackiego, pieni艅skiego pasa ska艂kowego, zachodnich Karpat zewn臋trznych, pod艂o偶a nasuni臋cia karpackiego na po艂udnie od Krakowa, neoge艅skiego wulkanizmu i budowy geologicznej niecki orawskiej. Wiercenie "Orawa" by艂oby usytuowane w rejonie Jab艂onki-Chy偶nego na linii przekroju sejsmicznego CELEBRATION CEL01, jak r贸wnie偶 w niedalekim s膮siedztwie g艂臋bokiego przekroju geologicznego Krak贸w-Zakopane i na linii przekroju Andrych贸w-Chy偶ne. Przekroje Krak贸w--Zakopane i Andrych贸w-Chy偶ne wykorzystuj膮 szereg wierce艅 Pa艅stwowego Instytutu Geologicznego i PGNiG, a tak偶e badania sejsmiczne i magnetote-luryczne. Usytuowanie wiercenia w rejonie przygranicznym pozwoli na mi臋dzynarodow膮 wsp贸艂prac臋 z geologami i geofizykami s艂owackimi. Wiercenie to ma na celu wyja艣nienie szeregu problem贸w badawczych. Jednym z nich jest zagadnienie m艂odych i wsp贸艂czesnych ruch贸w tektonicznych w Karpatach. Przez obszar karpacki przebiega granica europejskiego pola plam gor膮ca, wyznaczona neoge艅skim wulkanizmem oraz rozk艂adem strumienia cieplnego. Na obszarze pomi臋dzy G贸rn膮 Oraw膮 a G贸rnym 艢l膮skiem, linia graniczna 艂膮cz膮ca neoge艅skie wulkanity Zakarpacia z andezytami rejonu przypieni艅skiego i bazaltami Dolnego 艢l膮ska przecina sko艣nie nasuni臋cia jednostek fliszowych Karpat Zewn臋trznych. R贸wnocze艣nie w rejonie Orawy do pieni艅skiego pasa ska艂kowego sko艣nie dochodzi o艣 karpackiej, ujemnej anomalii grawimetrycznej, a pod艂o偶e skonsolidowane wyst臋puje na g艂臋boko艣ci nie wi臋kszej ni偶 6-9 km, a wi臋c w zasi臋gu g艂臋bokiego wiercenia, co sugeruj膮 wyniki bada艅 megnetotellurycznych (呕ytko, 1999) i magnetycznych. Podniesienie to, przy generalnym zapadaniu pod艂o偶a platformy europejskiej pod Karpaty ku po艂udniowi, mo偶e bya spowodowane warunkami geotermicznymi, na skutek podnoszenia si臋 astenosfery i wyst臋powania pi贸ropuszy p艂aszcza. Pi贸ropusze te mog膮 bya niezale偶ne od karpackiej kompresji i subdukcji. Z pi贸rpuszami tymi 艂膮czy si臋 lokalna i regionalna ekstensja w warunkach megaregionalnej kompresji. Zjawiska tego rodzaju nie s膮 jeszcze dok艂adnie poznane, aczkolwiek wyst臋puj膮 w kilku miejscach na 艣wiecie (np. Panteleria na Morzu 艢r贸dziemnym). Opracowanie zagadnienia roli pi贸ropuszy p艂aszcza i okre艣lenie ich relacji do kolizji i subdukcji maj膮 zasi臋g globalny, a ich wyja艣nienie w rejonie karpackim pozwoli na stworzenie uniwersalnego modelu ewolucji orogen贸w. Nie jest wykluczone, 偶e mamy do czynienia z orogenez膮 "modyfikowan膮" przez pi贸ropusz p艂aszcza. Powstanie niecki Orawy i Podhala mog艂oby wi臋c mie膰 zwi膮zek z riftingiem spowodowanym wp艂ywem pi贸ropuszy p艂aszcza na pograniczu dw贸ch p艂yt. Ryft ten jest obrze偶ony mi臋dzy innymi wyniesieniami Babiej G贸ry i Orawskiej Magury. Z ryftem mo偶e by膰 zwi膮zany wulkanizm ukryty pod neoge艅skimi utworami niecki orawskiej, a widoczny jako wysokooporowe cia艂a na profilach megnetotellurycznych. Tektonik臋 tego obszaru komplikuje wyst臋powanie uskok贸w przesuwczych o r贸偶nym przebiegu i orientacji i zwi膮zane z nimi tworzenie si臋 basen贸w mi臋dzyprzesuwczych typu pull-apart. Proponowane wiercenie przyczyni艂oby si臋 do uzyskania odpowiedzi na postawione wy偶ej problemy. Dla okre艣lenia dok艂adnej lokalizacji wiercenia i jego w艂a艣ciwej interpretacji geologicznej konieczne b臋dzie wykonanie dodatkowych prac geofizycznych. P艂ytka sejsmika wyja艣ni艂aby zasi臋g utwor贸w neoge艅skich i pozycj臋 pieni艅skiego pasa ska艂kowego pod utworami neogenu, za艣 g艂臋boka sejsmika, a zw艂aszcza zdj臋cie 3-D, przyczyni 艂aby si臋 do lepszego rozpoznania tektoniki wg艂臋bnej
