Excessive Daytime Sleepiness in Obstructive Sleep Apnea Patients Treated With Continuous Positive Airway Pressure: Data From the European Sleep Apnea…

2021

Excessive daytime sleepiness (EDS) is a symptom of obstructive sleep apnea (OSA) that resolves under treatment with continuous positive airway pressure (CPAP). In some patients, sleepiness persists despite CPAP treatment. We retrospectively analyzed data on subjective residual EDS, assessed as an Epworth Sleepiness Scale score (ESS) >10, in patients from the European Sleep Apnea Database (n = 4,853, mean age +/- SD 54.8 +/- 11.8 years, 26.1% females), at baseline and at the first visit (median follow-up: 5 months, interquartile range 3-13). An ESS > 10 occurred in 56% of patients at baseline and in 28.2% of patients at follow-up. Residual EDS was analyzed in 2,190 patients (age: 55.1 +/- 12…

A DNA‐Encoded FRET Biosensor for Visualizing the Tension across Paxillin in Living Cells upon Shear Stress

2022

Paxillin is a potential participant in the direct intracellular force transmission which is considered as the foundation of cells sensing and responding to extracellular environment. However, the detection of tension across paxillin has not been achieved due to lacking microsized tools. Herein, a paxillin tension sensor (PaxTs) based on Fluorescence Resonance Energy Transfer (FRET) technique was constructed. PaxTs can be expressed and assembled to FA sites spontaneously to visualize the tension across paxillin with FRET efficiency of ~62.4% in living cells. The tension across paxillin was found to decrease upon shear stress, in which the membrane fluidity and contractility of actin acted as…

ADHD leimana : vanhempien kokemukset lapsen sosiaalisen stigman rakentumisesta

2015

Erving Goffmanin sosiaalisen stigman teorian kautta on mahdollista tarkastella yksilöiden erilaisia ominaisuuksia, joihin ympäristö liittää poikkeavan merkityksen. Tässä tutkimuksessa stigma-attribuutin muodostaa ADHD ja tutkimuksen tarkoituksena on tarkastella niitä tekijöitä, jotka vaikuttavat ADHD:n muodostumisen attribuutista sosiaaliseksi stigmaksi. Tutkimuksen teoreettisen viitekehyksen muodostaa Goffmanin sosiaalisen stigman teoria, jota on tarkennettu sosiologisella poikkeavuuteen liittyvällä tarkastelulla. Tutkittavaa aihetta lähestytään maltillisen sosiaalisen konstruktionismin näkökulmasta, sillä stigma ymmärretään sosiaalisesti konstruoituneeksi ilmiöksi. Tutkimuksen aineiston a…

Influence of the Resin Layer Thickness at the Interface of Hybrid Metal-composite Co-cured Joints

2011

As discussed in literature, the accurate analysis of the modern co-cured joints between composite materials or between a metal and a composite material (hybrid joints) is complicated by the influence of the interface resin layer on the interface singular stress field. In such joints, in fact, there is not a proper adhesive layer and the thickness of the resin layer, that plays the role of the adhesive, is not constant due to the presence of the reinforcing fibers in the composite adherent. For this reason several authors assume that a generic co-cured joint can not be studied as a simple bi-material joint, without considering the particular characteristics of the actual resin layer. This pr…

Experimental Investigation on Stiffness and Strength of Single-Lap Z-Pinned Joints in a Laminated CFRP Stress-Ribbon Strip

2016

Carbon fiber-reinforced polymer (carbon-polymer) is an advanced lightweight composite material with high strength and excellent resistance to corrosion and fatigue. Over the past decades, application of fiber-reinforced polymers has been spread from the aerospace to other branches of industry such as automobile and civil engineering. Unidirectional carbon-polymers have a high potential for replacing steel in tensile members. Recently, the first carbonpolymer stress-ribbon bridge has been constructed in Germany. The non-laminated strip-loop carbon-polymer thin strips were used as the load bearing components in this bridge. In comparison with the laminated components, the applied cables are c…

ADHD symptoms and maladaptive achievement strategies: the reciprocal prediction of academic performance beyond the transition to middle school

2023

This longitudinal study examined how two externalising behaviour problems, attention-deficit hyperactivity disorder (ADHD) and conduct disorder (CDs), are associated over time with low motivation (MAS), and how these problems effect academic performance. In our cross-lagged analysis, we found reciprocal effects between ADHD symptoms and MAS between Grades 5 and 6. Both domains also negatively predicted later academic performance. With CDs and MAS, no cross-lagged effects were found, although both were correlated and very stable over time, and negatively predicted later academic performance. These different kinds of externalising problem behaviours seem to differ in the way in which they int…

Naturalne spoiwa kostek nawozowych jako element zrównoważonej uprawy roślin

2016

Zrównoważona uprawa roślin, stawiająca nowe wymagania praktyce rolniczej, dąży do ograniczania wykorzystania nawozów mineralnych na rzecz długo działających nawozów organicznych. W szczególności cenne są te nawozy, które powstają w obrębie gospodarstwa z uwagi na ich wysoką jakość oraz brak kosztów związanych z zakupem i transportem. Zwłaszcza materia organiczna zawarta w odpadach przemysłu spożywczego lub powstająca w gospodarstwach domowych, przy braku zanieczyszczeń innymi rodzajami odpadów, może służyć do wytwarzania nawozu, który mógłby być wykorzystywany nawet w organicznej produkcji roślin uprawnych. W pracy przedstawiono wyniki badań wiązania organicznych i mineralnych komponentów n…
