Harvesting the decay energy of 26 Al to drive lightning discharge in protoplanetary discs

Chondrules in primitive meteorites likely formed by recrystallisation of dust aggregates that were flash-heated to nearly complete melting. Chondrules may represent the building blocks of rocky planetesimals and protoplanets in the inner regions of protoplanetary discs, but the source of ubiquitous thermal processing of their dust aggregate precursors remains elusive. Here we demonstrate that esca

Hepatic Leukemia Factor Maintains Quiescence of Hematopoietic Stem Cells and Protects the Stem Cell Pool during Regeneration

The transcription factor hepatic leukemia factor (HLF) is strongly expressed in hematopoietic stem cells (HSCs) and is thought to influence both HSC self-renewal and leukemogenesis. However, the physiological role of HLF in hematopoiesis and HSC function is unclear. Here, we report that mice lacking Hlf are viable with essentially normal hematopoietic parameters, including an intact HSC pool durin

Obesity and metabolic disturbances in adamantinomatous craniopharyngioma patients

An adamantinous craniopharyngioma (CP) is rare benign pituitary tumour often growing invasively and thereby affecting the hypothalamus. The recurrence rate in CP is high and therapy of choice is surgery, followed by cranial radiotherapy (CRT) in about half of the patients. Patients with CP have a 3-19 fold higher cardiovascular mortality in comparison to the general population. The majority of pat

Investigation of the Combustion Characteristics with Focus on Partially Premixed Combustion in a Heavy Duty Engine

Partially Premixed Combustion (PPC) has shown its potential by combining high combustion controllability with emission characteristics that are close to those of an HCCI engine. In order to get PPC the ignition delay needs to be long enough for the fuel and air to mix prior to combustion. This can be achieved by injecting the fuel sufficiently early while running with high EGR.In order to find outPartially Premixed Combustion (PPC) has shown its potential by combining high combustion controllability with emission characteristics that are close to those of an HCCI engine.

Comprehensive Mass Spectrometric Survey of Streptococcus pyogenes Subcellular Proteomes

Streptococcus pyogenes is a major global health burden causing a wide variety of diseases. Because a vaccine against this bacterium is still lacking, vaccine candidates or antimicrobial therapies are urgently needed. Here we use an invasive and clinically relevant streptococcal M1 serotype to characterize the bacterial proteome in-depth. An elaborate fractionation technique is employed to separate

Tilting Catalyst-Free InAs Nanowires by 3D-Twinning and Unusual Growth Directions

Controlling the growth direction of nanowires is of strategic importance both for applications where nanowire arrays are contacted in parallel and for the formation of more complex nanowire networks. We report on the existence of tilted InAs nanowires on (111)B GaAs. The tilted direction is predominantly the result of a three-dimensional twinning phenomenon at the initial stages of growth, so far

Neurointensive care management of raised intracranial pressure caused by severe valproic acid intoxication

INTRODUCTION: We describe the neurointensive care (NIC) management of a patient with severe cerebral swelling and raised intracranial pressure (ICP) after severe sodium valproic acid (VPA) intoxication. A previously healthy 25-year old male with mild tonic-clonic epilepsy was found unconscious with serum VPA levels >10,000 micromol/l. The patient deteriorated to Glasgow Motor Scale score (GMS) 2 a

The nitrone free radical scavenger NXY-059 is neuroprotective when administered after traumatic brain injury in the rat

Reactive oxygen species (ROS) are important contributors to the secondary injury cascade following traumatic brain injury (TBI), and ROS inhibition has consistently been shown to be neuroprotective following experimental TBI. NXY-059, a nitrone free radical trapping compound, has been shown to be neuroprotective in models of ischemic stroke but has not been evaluated in experimental TBI. In the pr

Clinical outcome following surgical treatment for bilateral cerebellar infarction

OBJECTIVES: To analyze the initial clinical and radiological findings, the surgical treatment, and the clinical outcome following surgical decompression in patients with space-occupying bilateral cerebellar infarction.MATERIALS AND METHODS: Ten patients with expansive bilateral cerebellar infarction and decreased level of consciousness were operated with suboccipital craniectomy, removal of the in

The Swedish study of Irrigation-fluid temperature in the evacuation of Chronic subdural hematoma (SIC!) : study protocol for a multicenter randomized controlled trial

BACKGROUND: Chronic subdural hematoma (cSDH) is one of the most common conditions encountered in neurosurgical practice. Recurrence, observed in 5-30% of patients, is a major clinical problem. The temperature of the irrigation fluid used during evacuation of the hematoma might theoretically influence recurrence rates since irrigation fluid at body temperature (37oC) may beneficially influence coag

Plasma C4d as marker for lupus nephritis in systemic lupus erythematosus

Background: In the present study, we sought to evaluate the complement activation product C4d as a marker for lupus nephritis in systemic lupus erythematosus (SLE). Methods: C4d levels were determined by enzyme-linked immunosorbent assay in plasma samples of patients with established SLE using a novel approach based on detection of a short linear cleavage neoepitope. Cross-sectional associations w
