Predicted warming and browning affect timing and magnitude of plankton phenological events in lakes: a mesocosm study

1. Aquatic ecosystems in Northern Europe are expected to face increases in temperature and water colour (TB) in future. While effects of these factors have been studied separately, it is unknown whether and how a combination of them might affect phenological events and trophic interactions. 2. In a mesocosm study, we combined both factors to create conditions expected to arise during the coming ce

Large-scale association analysis provides insights into the genetic architecture and pathophysiology of type 2 diabetes

To extend understanding of the genetic architecture and molecular basis of type 2 diabetes (T2D), we conducted a meta-analysis of genetic variants on the Metabochip, including 34,840 cases and 114,981 controls, overwhelmingly of European descent. We identified ten previously unreported T2D susceptibility loci, including two showing sex-differentiated association. Genomewide analyses of these data

Study of a Pneumatic Hybrid aided by a FPGA Controlled Free Valve Technology System

Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. Today there are several solutions to meet the demand for better fuel economy and one of them is the

Isomeric Ratios in 206Hg

Hg-206 was populated in the fragmentation of an E/A = 1 GeV Pb-208 beam at GSI. It was part of a campaign to study nuclei around Pb-208 via relativistic Coulomb excitation. The observation of the known isomeric states confirmed the identification of the fragmentation products. The isomeric decays were also used to prove that the correlations between beam identification detectors and the AGATA gamm

Binding of vitronectin and Factor H to Hic contributes to immune evasion of Streptococcus pneumoniae serotype 3.

Streptococcus pneumoniae serotype 3 strains are highly resistant to opsonophagocytosis due to recruitment of the complement inhibitor Factor H via Hic, a member of the pneumococcal surface protein C (PspC) family. In this study, we demonstrated that Hic also interacts with vitronectin, a fluid-phase regulator involved in haemostasis, angiogenesis, and the terminal complement cascade as well as a c

RF Characterization of Vertical Wrap-Gated InAs/High-κ Nanowire Capacitors

This paper presents RF as well as low-frequency capacitance–voltage (C–V) characterization of vertical wrap-gated InAs/high-κ nanowire MOS capacitors. A full equivalent circuit model for traps is used to fit the low-frequency C–V characteristics, from which the interface trap density (Dit) and border trap density (Nbt) are evaluated separately. The results show comparable Nbt but far lower Dit (

Osteotomy of dorsally displaced malunited fractures of the distal radius: no loss of radiographic correction during healing with a minimally invasive fixation technique and an injectable bone substitute.

BACKGROUND AND PURPOSE: Malunion after a distal radius fracture can be treated with an osteotomy of the distal radius. Often autologous iliac crest bone graft is used to fill the gap, but this is associated with donor site morbidity. Instead of bone graft, we have used a slow-resorbing bone substitute in combination with a minimally invasive fixation technique. PATIENTS AND METHODS: 25 consecutive

Exciton-vibrational coupling in molecular aggregates: Electronic versus vibronic dimer

The influence of exciton-vibrational coupling on the energy level structure, oscillator strength, and relaxation dynamics is investigated for two different excitonic dimer models. As compared with a purely electronic dimer, the inclusion of local vibrational modes within a vibronic dimer gives rise to a complex energy level structure including avoided crossings and changes of the nature of the exc

Sleep quality, use of hypnotics and sleeping habits in different age-groups among older people

Background: Sleep disturbances are common among older people (>65 years). Further, long-term use of sedative-hypnotics in older people is associated with morbidity and mortality. However, older people represent a large span of life years, and few studies have included the oldest-old above 85 years. Aim: To investigate and compare sleep quality, use of hypnotics and sleeping habits in different age

Risks in the chemotherapy process and possibilities for improvement

Medications are of considerable help if healthcare providers are able to administer them to patients safely and appropriately. The medication use process is complex and a team of professionals – doctors, nurses, and pharmacists – work together with the patient for optimal treatment effect. The process involves many sub-processes and in every step there is a possibility for an error. Cytotoxic drug

Job 3:8-Cosmological Snake-Charming and Leviathanic Panic in a Near Eastern Setting

The author examines the intriguing mention of “those who curse Yamm” and “rouse Leviathan” in Job 3:8, and tries to relate these expressions to Near Eastern religious history. The old assumption that two texts inscribed on Aramaic incantation bowls indicate the full background of these expressions is challenged, and further evidence is sought in texts such as the Enuma Elish, the Gnosticizing “Hym

Analysis of genes encoding laminin beta 2 and related proteins in patients with Galloway-Mowat syndrome

Galloway-Mowat syndrome (GMS) is a rare autosomal recessive disorder characterized by early onset nephrotic syndrome and microcephaly with various anomalies of the central nervous system. GMS likely represents a heterogeneous group of disorders with hitherto unknown genetic etiology. The clinical phenotype to some extent overlaps that of Pierson syndrome (PS), which comprises congenital nephrotic

Assessment of natal origin of pike (Esox lucius) in the Baltic Sea using Sr:Ca in otoliths

Spawning habitat of pike (Esox lucius) in the Baltic Sea include brackish water bays, brooks and rivers. Elevated salinity concentrations are one of several stressors that might increase the use and importance of freshwater habitats for spawning. In the Baltic Sea, one of the largest brackish seas in the world, freshwater species like pike, perch (Perca fluviatilis), whitefish (Coregonus sp), brea

Effects of supplementation with n-3 polyunsaturated fatty acids on cognitive performance and cardiometabolic risk markers in healthy 51 to 72 years old subjects: a randomized controlled cross-over study

Background: Higher plasma n-3 polyunsaturated fatty acids (PUFA) have been associated with a lower risk of age related cognitive decline, and to beneficially affect cardiometabolic risk factors. A relation exists between metabolic disorders such as diabetes type 2 and cognitive decline. Results regarding the potential effects of n-3 PUFA on risk factors in healthy subjects are divergent, and studi

Evaluation of a previously suggested plasma biomarker panel to identify Alzheimer's disease.

There is an urgent need for biomarkers in plasma to identify Alzheimer's disease (AD). It has previously been shown that a signature of 18 plasma proteins can identify AD during pre-dementia and dementia stages (Ray et al, Nature Medicine, 2007). We quantified the same 18 proteins in plasma from 174 controls, 142 patients with AD, and 88 patients with other dementias. Only three of these proteins
