Ultraschall und Lavage beim stumpfen Bauchtrauma polytraumatisierter Patienten
2008
The reliability of sonography and peritoneal lavage in assessing the need for immediate surgical intervention in blunt abdominal trauma was examined in a controlled prospective and retrospective study. Whereas no false results occurred using peritoneal lavage, false negative findings in sonography were 9.8% and false positive findings 3.9%. A significant difference was also found on retrospective evaluation of all cases with diagnostic peritoneal lavage (2.2% false results) and ultrasound investigations (14.9% false results). This demonstrates that sonography cannot fully replace peritoneal lavage as a diagnostic method in blunt abdominal trauma.
Dissociation of airway responsiveness and bronchoalveolar lavage (BAL) cell composition in sensitized guinea-pigs after daily inhalation of ovalbumin
1994
Summary. The association between inflammatory cell influx, cell activation status and change of airway responsiveness to acelylcholine (ACh) after daily inhalation of ovalbumin (OA) in sensitized guinea–pigs was investigated. Starting 3 weeks after sensitization (OA at 50mg/kg s.c. + i.p.) guinea–pigs were exposed daily to 2% OA (10min: undercover of 0.5Smg/kg mepyramine i.p. 15min before OA) for 2 weeks. Concentration–response curves (CRCs) for inhaled ACh were performed 24 h after the last OA–challenge and 24 h after another single OA–inhalation 1 week later. CRCs for inhaled ACh were neither affected 24 h after the last OA challenge (daily for two weeks) nor 24 h after another OA–inhalat…
Ductal lavage: a way of carefully tracing the breast-secreting duct
2006
Background: Breast cancer is the most commonly diagnosed neoplasia in women after nonmelanoma skin tumors. Unfortunately, present-day diagnostic methods are unable to identify the presence of a cancer until it has been developing for several years. Currently, ductal lavage seems to represent a new method of reaching an early diagnosis of breast cancer. Materials & methods: This study analyzed 30 patients with ages ranging from 40 to 55 years; and in 26 of these patients, we were able to obtain a sufficient quantity of material for cytological and biomolecular analysis. Results & conclusion: We propose an easy, reproducible method that makes it possible to obtain a detailed map of the nipple…
Transmission of arterial oxygen partial pressure oscillations to the cerebral microcirculation in a porcine model of acute lung injury caused by cycl…
2013
Cyclic recruitment and derecruitment (R/D) play a key role in the pathomechanism of acute lung injury (ALI) leading to respiration-dependent oscillations of arterial partial pressure of oxygen (Pa(O(2))). These Pa(O(2)) oscillations could also be forwarded to the cerebral microcirculation.In 12 pigs, partial pressure of oxygen was measured in the thoracic aorta (Pa(O(2))) and subcortical cerebral tissue (Pbr(O(2))). Cerebral cortical haemoglobin oxygen saturation (Sbr(O(2))), cerebral blood flow (CBF), and peripheral haemoglobin saturation (Sp(O(2))) were assessed by spectroscopy and laser Doppler flowmetry. Measurements at different fractions of inspired oxygen (F(I(O(2)))) were performed …
Single and Synergistic Effects of Type 2 Cytokines on Eosinophils and Asthma Hallmarks
2020
Abstract The type 2 cytokines IL-5, IL-13, and IL-4 play an important role in the induction and progression of asthma. According to the Global Initiative for Asthma guidelines, blood eosinophil numbers are one marker that helps to guide treatment decisions in patients suffering from severe forms of asthma. Effects of type 2 cytokines were analyzed, alone or in combination, on eosinophils in blood and other compartments and on the development of asthma symptoms. C57BL/6 mice received a single intranasal application of equimolar amounts of IL-5, IL-13, and IL-4, alone or in combination. Numbers, activation state, and migratory behavior of eosinophils in bone marrow (BM), blood, lung, and bron…
The effect of dietary phosphorus deficiency on the immune responses of European whitefish (Coregonus lavaretus L.)
2003
Low phosphorous (P) feeds in aquaculture are recommended to reduce eutrophication of water systems. However, the feed should be adequate for normal growth and intact immune defence. Influence of low dietary P supply on non-specific and specific immune defence of European whitefish (Coregonus lavaretus) was studied in two trials. For Trial 1, a semi-purified, low-P diet was formulated and supplied with 0, 2.5, 5.0, 7.5, or 10.0 g P kg(-1)to obtain a P gradient of 4.4-14.9 g kg(-1)diet. Diets were fed to four replicate groups of fingerling whitefish for 42 days in a flow-through, freshwater system maintained at 15 degrees C. Fish fed with the P-unsupplemented diet had significantly lower plas…

Potentiel bioarchéologique de l’analyse des micro‐fossiles non‐polliniques : résultats préliminaires issus de deux opérations d’archéologie préventive
2019
International audience; Les micro‐fossiles non polliniques (MNP) constituent un vaste groupe de bioindicateurs (propagules ou forme de résistance, entre autres) issus de différents organismes (champignons, algues, plancton, bactérie, animaux, végétaux etc.). Si leur analyse est désormais fréquente dans les études palynologiques menées dans les milieux naturels (lacs ou zones humides), les MNP sont encore peu exploités en contexte archéologique. Leur potentiel bioarchéologique reste à évaluer mais l’enjeu est grand tant les informations qu’ils peuvent apporter sont nombreuses aussi bien sur le plan paléoenvironnemental que paléoécologique, géoarchéologique ou taphonomique. L’éventail de site…
Onnellisia opiskelijoita keskellä poliittista muutosta : Tarton yliopistossa opiskelleiden virolaisten muistot Viron uudelleenitsenäistymistä edeltän…
2017
Neuvostoliiton hajoamisesta ja sitä kautta Viron uudelleenitsenäistymisestä tuli vuonna 2016 kuluneeksi 25 vuotta. Näiden vuosien aikana virolaiset muiden entisten neuvostokansojen tavoin ovat käyneet läpi neuvostomenneisyyttään ja tuolloisista nuorista aikuisista on kasvanut se sukupolvi, joka on nykyisessä Virossa päättävässä asemassa ja siirtää historiakäsityksiään uusille, itsenäisessä Virossa syntyneille sukupolville. Maisterintutkielmassani tutkin miten tämä 1960- ja 1970-lukujen taitteessa syntynyt sukupolvi muistaa 1980- ja 1990-lukujen taitteen tapahtumat ja heidän oman sukupolvensa roolin niissä. Kyseistä aikaa käsittelevä historiankirjoitus on tavallisesti keskittynyt makrotason …
