Parkinson's disease varies widely in clinical manifestations, course of progression and biomarker profiles from person to person. Identification of distinct Parkinson's disease subtypes is of great priority to illuminate underlying pathophysiology, predict progression and develop more efficient personalized care approaches. There is currently no clear way to define and divide subtypes in Parkinson's disease. Using data from the Parkinson's Progression Markers Initiative, we aimed to identify distinct subgroups via cluster analysis of a comprehensive dataset at baseline (i...

Yield is subject to strong Genotype by Environment interactions (G x E) in the field, especially under abiotic constraints such as soil water deficit (Drought, D) and high temperature (Heat, H). Since environmental conditions show strong fluctuations during the whole crop cycle, geneticists usually do not consider the environmental measures as quantitative variables, but rather as factors in multi-environment analyses. Based on 11 experiments in a field platform with contrasted temperature and soil water deficit, we determined the periods of sensitivity to drought and heat constraints in wheat (Triticum aestivum L...

Hyperbaric oxygen therapy (HBOT) is a noninvasive widely applied treatment that increases the oxygen pressure in tissues. In cochlear implant (CI) research, intracochlear application of neurotrophic factors (NTFs) is able to improve survival of spiral ganglion neurons (SGN) after deafness. Cell-based delivery of NTFs such as brain-derived neurotrophic factor (BDNF) may be realized by cell-coating of the surface of the CI electrode. Human mesenchymal stem cells (MSC) secrete a variety of different neurotrophic factors and may be used for the development of a biohybrid electrode in order to release endogenously-derived neuroprotective factors for the protection of residual SGN and for a guided outgrowth of dendrites in the direction of the CI electrode...

Thermoluminescence property of a phosphor is an important parameter that helps to determine the use of a phosphor in various dosimetric applications. In this study, the thermoluminescence behaviour of a monoclinic Gd2O3:Er(3+);Yb(3+) nanophosphor was studied. Gd2O3:Er(3+);Yb(3+) nanophosphor was prepared using a combustion synthesis method. Structural characterization was carried out via X-ray diffraction and electron microscopy methods. Herein, thermoluminescence (TL) study and kinetic analysis of the UV- and gamma-irradiated phosphor was also carried out...

This study was undertaken to investigate whether, in rat interactive activities, recurring sequences of behavioural events might be identified and how and to what extent each component of the pair is involved. To this aim, the multivariate temporal-pattern (t-pattern) analysis was applied to the social interactions of 9 pairs of male Wistar rats tested in open field. Interactive activities were classified into intra- and inter-subjects. Quantitative evaluations showed that intra-subject behavioural elements represented 62...

INTRODUCTION: Replacing sedentary behaviour with light intensity physical activity (ie, activities classified as less than three metabolic equivalents, such as slow-paced walking) may be a more realistic strategy for reducing cardiometabolic risk in people with chronic obstructive pulmonary disease than only aiming to increase levels of moderate-vigorous intensity physical activity. Behaviour change interventions to reduce sedentary behaviour in people with chronic obstructive pulmonary disease have not yet been developed or tested...

BACKGROUND: Migrants in many European countries including Germany tend to utilize preventive measures less frequently than the majority population. Little is known about the dental health of migrants as well as about their oral health behaviour, particularly in the adult population. The aim of this study was to examine differences in the uptake of annual dental check-ups in adult migrants and non-migrants in Germany. METHODS: We used data from the cross-sectional survey 'German Health Update 2010' conducted by the Robert Koch Institute (n = 22,050)...

Pyochelin (PCH) is a siderophore (extracellular chelator) produced by the pathogenic bacterium Pseudomonas aeruginosa (PAO). PCH is implicated in iron (Fe(3+)) transport to PAO, and is crucial for its metabolism and pathogenicity. Due to the chemical similarity with Fe(3+), gallium (Ga(3+)) interferes with vital iron-dependent processes in bacterial cells, thereby opening new perspectives for the design of specific metal-based antibacterial drugs. However, the structural basis for the Fe(3+)-mimetic properties of Ga(3+) complexed with the PCH siderophore is still lacking...

Single conventional columns in reversed-phase LC are insufficient for analysing the isoindoles of primary amino acids, due to their limited functionality. An interesting possibility for increasing the separation power is the combination of several columns of different nature, where the length is modified by coupling small segments. This approach may require a considerable investment to have multiple lengths for each stationary phase. However, the combination of only two columns of fixed length can be enough to resolve satisfactorily relatively complex mixtures, provided that an optimised gradient program is applied...

Cancer of the nasopharynx displays an unparalleled skewness of its epidemiologic, pathogenic and clinico-prognostic characteristics depending on the geographic location. Between the endemic and sporadic forms, which occur in Southeastern Asia and Northern America, respectively, intermediate incidence is noted around the Mediterranean. This study describes the patterns of the disease affecting the population of Western Greece. The records of 70 patients with nasopharyngeal cancer diagnosed in a single institution between 1994-2014 were retrospectively reviewed...

Developments in non-invasive diffusion MRI tractography techniques have permitted the investigation of both the anatomy of white matter pathways connecting grey matter regions and their structural integrity. In parallel, there has been an expansion in automated techniques aimed at parcellating grey matter into distinct regions based on functional imaging. Here we apply independent component analysis to whole-brain tractography data to automatically extract brain networks based on their associated white matter pathways...

INTRODUCTION: Rotenone, a mitochondrial complex I inhibitor is used as a neurotoxin agent to reproduce the neuropathological, and behavioural feature of Parkinson's Disease (PD) in rat. Due to acute and chronic exposure of rotenone with various doses through different routes of administration, mortality is being reported. Low dose takes a longer duration to produce PD symptoms in animals. This present study was designed to create hemiparkinsonian 'partial' lesion model by rotenone at a single moderate dose in two sites of striatum in albino rats and also to assess its toxicity by behavioural parameters and by microscopic study...

M Gunkel, E Pawlowsky-Reusing
As part of the project KURAS, the Berliner Wasserbetriebe realized a field campaign in 2015 in order to increase the process knowledge regarding the behaviour of transported sediment in the pressure main leading from the pumpstation to the wastewater treatment plant. The field campaign was conducted because of a lack of knowledge about the general condition of the pressure main due to its bad accessibility and the suspicion of deposits caused by hydraulic underload. The practical evidence of the sediment transport performance of this part of the sewer system, dependent on different load cases, should present a basis for further analysis, for example regarding flushing measures...

Early detection of alcohol and drug abuse among adolescents is decisive not only for rapid referral and intervention in cases of risk, but also as an indicator for use in the evaluation of prevention programs and public policies to reduce consumption. One of the most widely-used screening instruments in the world is the Problem Oriented Screening Instrument for Teenagers (POSIT) (Rahdert, 1991), whose substance use and abuse subscale (POSITUAS) is a brief tool of enormous applied potential. However, there is still no empirical validation study that would ensure its good psychometric performance in Spain...

Crohns Disease (CD) is a relapsing inflammation of the gastrointestinal tract that affects a young working age population and is increasing in developing countries. Half of all sufferers will experience stricturing or fistulizing intestinal complications that require extensive surgical interventions and neither genes nor clinical risk factors can predict this debilitating natural history. We applied discovery and verification phase studies as part of an NCI-FDA modelled biomarker pipeline to identify differences in the low-mass (<25kDa) blood-serum proteome between CD behavioural phenotypes...

The term "food literacy" describes the idea of proficiency in food related skills and knowledge. This prevalent term is broadly applied, although its core elements vary from initiative to initiative. In light of its ubiquitous use-but varying definitions-this article establishes the scope of food literacy research by identifying all articles that define 'food literacy', analysing its key conceptualizations, and reporting outcomes/measures of this concept. METHODS: A scoping review was conducted to identify all articles (academic and grey literature) using the term "food literacy"...

BACKGROUND: Neonatal monosodium glutamate (MSG) treatment triggers excitotoxicity and induces a degenerative process that affects several brain regions in a way that could lead to epileptogenesis. Na(+)/Ca(2+) exchangers (NCX1-3) are implicated in Ca(2+) brain homeostasis; normally, they extrude Ca(2+) to control cell inflammation, but after damage and in epilepsy, they introduce Ca(2+) by acting in the reverse mode, amplifying the damage. Changes in NCX3 expression in the hippocampus have been reported immediately after neonatal MSG treatment...
