Empowering young people-the impact of camp experiences on personal resources, well-being, and community building.

Introduction: Personal resources and resources of the sociocultural environment help children and adolescents to successfully cope with challenges in everyday life, which is associated with better individual well-being. SCOUT, the 'Study on Competence development in OUT-of-school settings', investigated whether participation in a summer camp enhanced adolescents' personal resources, well-being, and readiness to contribute to the community.

Methods: The research took place during the Swiss National Jamboree of the Swiss Guide and Scout Movement, a two-week event in the summer of 2022, with a paper-pencil pretest (beginning of the camp - T1) and posttest (end of the camp - T2) survey ( = 607, aged 14-17).

Hexoprenaline Compared with Atosiban as Tocolytic Treatment for Preterm Labor.

Preterm birth is defined as a live birth before 37 weeks of gestation and is associated with increased neonatal morbidity and mortality. The aim of this study is to compare the efficacy of hexoprenaline and atosiban for short- and long-term tocolysis and their effects on neonatal and maternal outcomes. This retrospective cohort study included women with threatened preterm labor between 24 + 0 and 34 + 0 weeks of gestation without premature rupture of membranes.

Separation of the mineral oil aromatic hydrocarbons of three and more aromatic rings from those of one or two aromatic rings.

An analytical method was developed for the quantitation of the mineral oil aromatic hydrocarbons in cosmetic raw materials separating those of one or two aromatic rings from those of three and more aromatic rings. Normal phase high performance liquid chromatography was used with donor-acceptor complex chromatography. The composition of both fractions and the quantities of respective compounds were determined by comprehensive two dimensional gas chromatography with time of flight mass spectrometry and by liquid chromatography coupled to gas chromatography with flame ionization detection.

The influence of molecular structure on odor qualities and odor detection thresholds of volatile alkylated phenols.

The relationship between chemical structure and odor characteristics of aroma compounds is interesting in terms of establishing a fundamental understanding and, in the long term, a perspective for the prediction of odor qualities and intensities of unknown compounds; on the other hand, such studies provide a useful tool to analytically elucidate compounds that are exceptionally potent odor contributors to a specific smell. In this respect, a broad knowledge of compounds with regard to their odor threshold and smell specificities compiled in a comprehensive odor library would drastically simplify the chemoanalytical process in identifying aromas and smells. Whereas numerous odor-active substance classes have been investigated intensively, such relationships and fundamental data have hitherto not been established for volatile phenols.

Clinical experience in the treatment of normal tension glaucoma with latanoprost in Germany.

Aims: The aim of this analysis was to evaluate the general ophthalmologist's experience in using latanoprost to treat normal tension glaucoma (NTG) patients.

Methods: NTG patients included in this study were part of an observational cohort of patients that were changed from previous therapy to latanoprost in Germany.

Results: This study included 200 NTG glaucoma patients who were being treated with latanoprost monotherapy (average duration, 1.

Endothelial nitric oxide synthase plays a minor role in inhibition of arterial thrombus formation.

Endothelial NO synthase (eNOS) expressed in the vascular endothelium or formed within platelets was postulated to inhibit platelet activation and aggregation. We have assessed the role of eNOS in platelet aggregation in vitro and in vivo by comparison of WT and eNOS-/- mice. Aggregometer studies revealed that collagen over a concentration range of 0.

Quantitation of odor-active compounds in rye flour and rye sourdough using stable isotope dilution assays.

Application of the aroma extract dilution analysis on a flavor distillate prepared from freshly ground rye flour (type 1150) revealed 1-octen-3-one (mushroom-like), methional (cooked potato), and (E)-2-nonenal (fatty, green) with the highest flavor dilution (FD) factors among the 26 odor-active volatiles identified. Quantitative measurements performed by stable isotope dilution assays and a comparison to the odor thresholds of selected odorants in starch suggested methional, (E)-2-nonenal, and hexanal as contributors to the flour aroma, because their concentrations exceeded their odor thresholds by factors >100. Application of the same approach on a rye sourdough prepared from the same batch of flour revealed 3-methylbutanal, vanillin, 3-methylbutanoic acid, methional, (E,E)-2,4-decadienal, 2,3-butanedione, and acetic acid as important odorants; their concentrations exceeded their odor thresholds in water and starch by factors >100.

Determination of key aroma compounds in the crumb of a three-stage sourdough rye bread by stable isotope dilution assays and sensory studies.

An investigation of the volatile fraction of a freshly prepared sourdough rye bread crumb by means of the aroma extract dilution analysis (AEDA), followed by identification experiments, revealed 22 flavor compounds in the flavor dilution (FD) factor range of 128 to 2048. Quantitations performed by stable isotope dilution assays (SIDA) and a calculation of odor activity values (OAV; ratio of concentration to odor threshold) revealed the following as contributors to the overall crumb flavor: 3-methylbutanal (malty), (E)-2-nonenal (green, fatty), (E,E)-2,4-decadienal (fatty, waxy), hexanal (green), acetic acid (sour, pungent), phenylacetaldehyde (honey-like), methional (boiled potato-like), vanillin (vanilla-like), 2,3-butandione (buttery), 3-hydroxy-4,5-dimethyl-2(5H)-furanone (spicy), and 2- and 3-methylbutanoic acid (sweaty). Using either citrate buffer, starch, or deodorized crumb as model matrixes, the typical malty and sour rye bread crumb flavor was reproduced by adding a mixture of 20 reference odorants in the "natural" concentrations as quantitatively determined in the fresh crumb.

Influence of mycophenolic acid and FK-506 on human platelet activation in vitro.

Background/aim: FK-506 (FK) and mycophenolic acid (MPA) are immunosuppressive agents used in kidney transplant recipients. Their effect on posttransplant thromboembolic complications is either controversial (FK) or has not been described (MPA). Thromboembolic events are among the consequences of platelet hyperaggregability which can be identified by measuring platelet aggregation.

Pulmonary hypertension in patients with chronic pulmonary thromboembolism: chest radiograph and CT evaluation before and after surgery.

The purpose of this study was to assess the value of morphometric data on conventional radiography and CT predicting the presence and degree of pulmonary hypertension and to assess the reversibility after surgery. On preoperative X-ray films and CT scans of 50 patients with pulmonary hypertension secondary to chronic thromboembolism, we measured the cardiothoracic ratio, basal diameter, length of cardiac contact to sternum, pulmonary trunk, right and left descending pulmonary artery, and the septum angle. These data were correlated with pulmonary arterial pressure.

[Contusion-suction trauma after globe injuries].

An analysis of ball injuries treated during the last 3 years at Münster University Eye Hospital revealed a difference in the kind of traumata caused by air-filled balls and by solid, inelastic balls. The pathomechanism of a "contusion-suction trauma" is discussed; this would offer a satisfactory explanation not only for injuries of the anterior segment, but also for retinal changes at the outer periphery and the posterior pole.

[Isotachophoretic determination of preservatives (author's transl)].

The preservatives sorbic acid, benzoic acid, methyl-, ethyl-, propylester of p-hydroxybenzoic acid and propionic acid can be determined quantitatively in one step by isotachophoretic separation based on the different electrophoretic mobilities of these compounds. The determination involves a direct extraction step in the so called Extrelut-columns, where the preservatives are separated from the food sample, mainly from the lipid phase. The whole analysis procedure is short and recoveries for the preservatives in the samples tested are very good.
