DcuA of aerobically grownEscherichia coliserves as a nitrogen shuttle (L‐aspartate/fumarate) for nitrogen uptake

2018

DcuA of Escherichia coli is known as an alternative C4 -dicarboxylate transporter for the main anaerobic C4 -dicarboxylate transporter DcuB. Since dcuA is expressed constitutively under aerobic and anaerobic conditions, DcuA was suggested to serve aerobically as a backup for the aerobic (DctA) transporter, or for the anabolic uptake of C4 -dicarboxylates. In this work, it is shown that DcuA is required for aerobic growth with L-aspartate as a nitrogen source, whereas for growth with L-aspartate as a carbon source, DctA was needed. Strains with DcuA catalyzed L-aspartate and C4 -dicarboxylate uptake (like DctA), or an L-aspartate/C4 -dicarboxylate antiport (unlike DctA). DcuA preferred L-asp…

Muscle resting and TGF-β inhibitor treatment prevent fatty infiltration following skeletal muscle injury

2019

Background/Aims: Skeletal muscle injuries are the most common type of injury occurring in sports, and investigating skeletal muscle regeneration as well as understanding the related processes is an important aspect of the sports medicine field. The process of regeneration appears to be complex and precisely orchestrated, involving fibro-adipogenic progenitors (FAPs) which are a muscle-resident stem cell population that appears to play a major role in abnormal development of fibrotic tissue or intermuscular adipose tissue (IMAT). Our present study aims to investigate whether muscle resting or endurance exercise following muscle injury may change the behavior of FAPs and subsequently impact t…

Vācu valoda kā svešvaloda. Latviešu un angļu valoda – palīgs vācu valodas apguvē

2016

Šajā darbā tiek pētītas jaunas alternatīvas mācību prakses vācu valodas kā svešvalodas mācīšanai pieaugušajiem un demonstrētas jaunas pieejas šo mācību optimizēšanai. Svarīgākais instruments ir vairāku valodu izmantošana mācību laikā, īpaši, latviešu un angļu. Šī darba mērķis ir pārbaudīt un pilnveidot pašlaik valodu apguves procesā izmantotās metodoloģijas piemērotību. Darbā izklāstīts pētāmā jautājuma teorētiskais pamatojums; praktiskajā daļā īpaši detalizēti tiek analizēti jauni, autora izstrādāti valodas mācību materiāli.

Prävention nach akutem Koronarsyndrom

2014

Das akute Koronarsyndrom hat eine erhohte Mortalitat auch im Verlauf nach erfolgreicher interventioneller Therapie. Entscheidend ist die Beurteilung, ob sich im Anschluss an das ACS eine Herzinsuffizienz entwickelt. In der Differenzierung des myokardialen Schadens als auch der Bestimmung des Verlustes an Funktion spielt die nichtinvasive Bildgebung eine besondere Bedeutung. Hinsichtlich der sekundaren Pravention richtet sich die nicht-medikamentose als auch medikamentose Therapie nach der myokardialen Funktion und dem Vorhandensein oder Fehlen einer Herzinsuffizienz. Ausdauerbelastung spielt bei den nicht-medikamentosen Masnahmen in der Rehabilitation je nach Schwere der Schadigung des Herz…

The role of exercise on peripheral nerve regeneration: from animal model to clinical application

2021

Peripheral nerve injury is a complex condition with a variety of signs and symptoms depending on the severity and nerves involved. Peripheral nerve damage may lead to sensory and motor functions deficits and even lifelong disability, causing important socioeconomic costs worldwide. Despite the increase in knowledge of the mechanisms of injury and regeneration, a full functional recovery is still unsatisfying in the majority of patients. It is well known that exercise promotes physical and psychological well-being, by ameliorating general health. In the last years, there has been a growing interest in evaluating the effects of exercise on the peripheral nervous system. Experimental works wit…

RELEASE OF HEMOPOIETIC AND ENDOTHELIAL PROGENITORS AFTER ENDURANCE AND MAXIMAL EXERCISE IN RUNNERS

2007

2020

Background Dental professionals are subjected to higher risks for musculoskeletal disorders (MSDs) than other professional groups, especially the hand region. This study aims to investigate the prevalence of hand complaints among dentists (Ds) and dental assistants (DAs) and examines applied therapies. Methods For this purpose, an online questionnaire analysed 389 Ds (240female/149male) and 406 DAs (401female/5male) working in Germany. The self-reported data of the two occupational groups were compared with regard to the topics examined. The questionnaire was based on the Nordic Questionnaire (self-reported lifetime, 12-month and 7-day MSDs prevalence of the hand, the conducted therapy and…

Nutrition Knowledge Is Associated with Energy Availability and Carbohydrate Intake in Young Female Cross-Country Skiers

2021

The aim of this study was to provide information on energy availability (EA), macronutrient intake, nutritional periodization practices, and nutrition knowledge in young female cross-country skiers. A total of 19 skiers filled in weighted food and training logs before and during a training camp. Nutrition knowledge was assessed via a validated questionnaire. EA was optimal in 11% of athletes at home (mean 33.7 ± 9.6 kcal·kgFFM−1·d−1) and in 42% at camp (mean 40.3 ± 17.3 kcal·kgFFM−1·d−1). Most athletes (74%) failed to meet recommendations for carbohydrate intake at home (mean 5.0 ± 1.2 g·kg−1·d−1) and 63% failed to do so at camp (mean 7.1 ± 1.6 g·kg−1·d−1). The lower threshold of the pre-ex…

Psychodynamic Motivation and Training program (PMT) for the secondary prevention in patients with stable coronary heart disease: study protocol for a…

2013

Background Nonpharmacological secondary prevention of coronary heart disease is considered a safe and effective measure to substantially reduce mortality. Despite the effectiveness of lifestyle changes, the compliance rate of patients is very low mainly due to psychosocial barriers. Psychotherapeutic approaches that address how persons think about themselves and their behaviors appear to have a significant potential for improving health behavior. Methods/design Against this background, our study aims to examine the feasibility and effects of a Psychodynamic Motivation and Training program (PMT) as compared to one session of advice in exercise training (EX) and treatment as usual (TAU). For …

Distinct trajectories of physical activity and related factors during the life course in the general population: a systematic review

2019

Background In recent years, researchers have begun applying a trajectory approach to identify homogeneous subgroups of physical activity (PA) in heterogeneous populations. This study systematically reviewed the articles identifying longitudinal PA trajectory classes and the related factors (e.g., determinants, predictors, and outcomes) in the general population during different life phases. Methods The included studies used finite mixture models for identifying trajectories of PA, exercise, or sport participation. Three electronic databases, PubMed (Medline), Web of Science, and CINAHL, were searched from the year 2000 to 13 February 2018. The study was conducted according to the PRISMA rec…
