Preoperative pulmonary hypertension and its impact on survival after heart transplantation.

Abstract Objectives. Pulmonary hypertension (PH) due to left heart disease may impair outcome after heart transplantation (HT). To evaluate to what extent previous, and present, haemodynamic criteria discriminate the impact of pre-operative-PH on survival, we characterized the PH in our HT-patients according to ESC's guidelines, ISHLT's summary statement and ISHLT's relative contraindications and

Systematic Screening of BK Virus by Real-Time PCR Prevents BK Virus Associated Nephropathy in Renal Transplant Recipients

BK virus associated nephropathy occurs in approximately 5% of renal transplant recipients. Quantitation of BKV DNA in serum/plasma early in the course of disease has been suggested to be an important diagnostic tool for polymavirus-associated nephropathy (PVAN). The aim of this study was to develop a BKV real-time PCR (qPCR), which could be included in a diagnostic qPCR platform. Additionally, the

RuS2 thin films as oxygen-evolving electrocatalyst: Highly oriented growth on single-crystal FeS2 substrate and their properties compared to polycrystalline layers

The compound semiconductor RuS2, known as mineral laurite, has been investigated as a potential (photo) electrochemically active anode material for the oxygen evolution in the process of (photo) electrolytic water splitting. The contribution describes for the first time the preparation of RuS2 thin films deposited on (100)- and (111)-oriented FeS2 (pyrite) substrates using reactive magnetron sputt

Katatopygia gen. n., a monophyletic branch segregated from Boletina (Diptera, Mycetophilidae)

The genus Katatopygia gen. n. is proposed for the Boletina erythropyga/punctus-group that was first introduced by Garrett (1924, 1925) and currently comprises eight described species. Molecular studies have strongly indicated that this group forms a monophyletic sister-group to a clade consisting of all other Boletina, Coelosia and Gnoriste, and its monophyly is supported by morphological data as

Toward a standardised thermal-optical protocol for measuring atmospheric organic and elemental carbon: the EUSAAR protocol

Thermal-optical analysis is a conventional method for determining the carbonaceous aerosol fraction and for classifying it into organic carbon, OC, and elemental carbon, EC. Unfortunately, the different thermal evolution protocols in use can result in a wide elemental carbon-to-total carbon variation by up to a factor of five. In Europe, there is currently no standard procedure for determining the

Emotional arousal and lexical specificity modulate response times differently depending on ear of presentation in a dichotic listening task

We investigated possible hemispheric differences in the processing of four different lexical semantic categories: SPECIFIC (e.g. bird), GENERAL (e.g. animal), ABSTRACT (e.g. advice), and EMOTIONAL (e.g. love). These wordtypes were compared using a dichotic listening paradigm and a semantic category classification task. Response times (RTs) were measured when participants classified testwords as co

Phylogenetic position of the diatom genus Geissleria Lange-Bertalot & Metzeltin and description of two new species from Siberian mountain lakes

Two new Geissleria species from Siberian mountain lakes Baikal and Frolikha are described based on molecular and morphological data. The two new species are Geissleria baicalosimilis Kulikovskiy, Gusev, Andreeva & Annenkova sp. nov. and G. frolikhiensis Kulikovskiy, Gusev, Andreeva & Annenkova sp. nov. According to partial 18S rDNA and rbcL gene fragment analyses, Geissleria does not belon

The Use and Productivity of Past Tense Morphology in Specific Language Impairment: An Examination of Danish

Purpose: The authors' primary goal was to investigate the potential of past tense inflection as a clinical marker of Danish specific language impairment (SLI). They also wished to test the predictions of the extended optional infinitive (EOI) account and processing based accounts of SLI on Danish. Method: Using sentence completion and sentence repetition tasks, the authors investigated the use of

Plasma levels of high-sensitive C-reactive protein do not correlate with inflammatory activity in carotid atherosclerotic plaques.

It is well established that subjects with moderately elevated plasma levels of C-reactive protein (CRP) have an increased risk of development of cardiovascular events. As atherosclerosis is a disease characterized by chronic arterial inflammation, it is possible that moderate increases in CRP level reflect the presence of plaque inflammation. To investigate this possibility we compared plasma leve

Enhanced colonic tumorigenesis in alkaline sphingomyelinase (NPP7) knockout mice.

Intestinal alkaline sphingomyelinase (alk-SMase) generates ceramide and inactivates platelet-activating factor (PAF) and is previously suggested to have anticancer properties. The direct evidence is still lacking. We studied colonic tumorigenesis in alk-SMase knockout (KO) mice. Formation of aberrant crypt foci (ACF) was examined after azoxymethane (AOM) injection. Tumor was induced by AOM alone,

Climate change and invasion by intracontinental range-expanding exotic plants: the role of biotic interactions

In this Botanical Briefing we describe how the interactions between plants and their biotic environment can change during range-expansion within a continent and how this may influence plant invasiveness. We address how mechanisms explaining intercontinental plant invasions by exotics (such as release from enemies) may also apply to climate-warming-induced range-expanding exotics within the same co

Climate change and poverty: building resilience of rural mountain communities in South Sikkim, Eastern Himalaya, India

The rural mountain communities have long faced challenges from a range of social, economic, political and environmental factors and the threat from these factors has only intensified due to the current climate change. This study was conducted in South Sikkim, a mountain region located in the Indian Eastern Himalaya, to get a deeper insight of the multitude of barriers and stresses that a poor rura

Reduced Irregularity of Ventricular Response During Atrial Fibrillation and Long-term Outcome in Patients With Heart Failure.

Reduced heart rate variability (HRV) is associated with poor outcome in patients with heart failure (HF). However, the data on predictive value of RR variability during atrial fibrillation (AF) are limited. Therefore, the aim of this study was to evaluate the association between ventricular response characteristics and long-term clinical outcome in the population of ambulatory patients with mild-t

Does gemcitabine-based combination therapy improve the prognosis of unresectable pancreatic cancer?

AIM: To assess whether gemcitabine-based combination therapy improves the prognosis of unresectable pancreatic cancer compared with gemcitabine treatment alone. METHODS: A quantitative up-to-date meta-analysis was undertaken to investigate the efficacy of gemcitabine-based combination treatment compared with gemcitabine monotherapy in locally advanced or metastatic pancreatic cancer. Inclusion was
