Background: The humerus is the second most common long-bone site of metastatic bone disease. We report complications, risk factors for failure, and survival of a large series of patients operated on for skeletal metastases of the humerus. Materials and methods: This study was based on 208 patients treated surgically for 214 metastatic lesions of the humerus. Reconstructions were achieved by intram

In this work the syntheses, structure and SOD activity of covalently grafted Fe(III)-complexes formed with various N- or C-protected amino acid ligands (L-histidine and L-tyrosine) inspired by the active site of the Fe SOD enzyme are presented. Chloropropylated silica gel was used as support to mimic the proteomic skeleton of the enzyme. Anchored complexes having uniform amino acids as well as the

Analysis of the novel Die Ästhetik des Widerstands (The Aesthetics of Resistance) by German-Swedish author Peter Weiss (1916-1982). The main question in the analysis is how the novel depicts the the literary work, since the narrator of the novel is a writer.

Popular Abstract in Swedish Graviditetsdiabetes (GDM) definieras som förhöjt blodglukos (blodsocker) som uppstår eller upptäcks under graviditet och som oftast försvinner efter förlossningen. Orsaken anses vara en otillräcklig förmåga att öka insulinproduktionen i takt med det ökade behov som normalt uppträder under en graviditet till följd av hormonella förändringar. Livsstilsfaktorer såsom stillGestational diabetes mellitus (GDM) is associated with a risk of adverse pregnancy outcome and is a predictor of subsequent diabetes. The aims of this work were to describe a reliable routine to diagnose abnormal glucose tolerance during pregnancy, to investigate women’s opinions of the specialist care provided, to determine the prevalence of diabetes one year after giving birth, and to elucidate

Aims and objectives. This study aimed to describe and identify risk factors associated with hospital-acquired pressure ulcers among adults in an acute care hospital compared with patients with pre-existing pressure ulcers present on admission. A further aim was to identify the preventive measures performed with both groups respectively. Background. Pressure ulcers occur most often in older and imm

The unperturbed neutron brightness of a moderator can be defined from the number of neutrons leaving the surface of a moderator completely surrounded by a reflector. Without openings for beam extraction, it is the maximum brightness that can be theoretically achieved in a moderator. The unperturbed brightness of a cylindrical cold moderator filled with pure para-H-2 was calculated using MCNPX; the

Energy policies in China, the world’s largest energy consumer, are an important factor in shaping the 41 global energy system. While scholars agree that energy security is a major driver of China’s energy 42 policies, there is insufficient understanding of what exactly constitutes China’s energy security from the 43 policy perspective. We apply recent insights from the Global Energy Assessment, pa

Survival of patients with locally advanced head and neck squamous cell cancer(HNSCC)is poor, with an overall survival < 50%, despite diagnostic and therapeutic advances. The identification of prognostic and predictive markers could help optimizing treatment. From 18 patients, six tumour cell lines were established and four were xenografted to nude mice. Proliferation parameters(cell doubling time,

Results are presented of searches for the production of supersymmetric particles decaying into final states with missing transverse momentum and exactly two isolated leptons in root s = 7 TeV proton-proton collisions at the Large Hadron Collider. Search strategies requiring lepton pairs with identical-sign or opposite-sign electric charges are described. In a data sample corresponding to an integr

Alkane C-H bond activation by various catalysts and enzymes has attracted considerable attention recently, but many issues are still unanswered. The conversion of ethane to ethanol and ethene by bare [Fe-III=O](+) has been explored using density functional theory and coupled-cluster method comprehensively. Two possible reaction mechanisms are available for the entire reaction, the direct H-abstrac

Background: The aim of this study was to compare maternal labour and birth outcomes between women who gave birth on a birth seat or in any other position for vaginal birth and further, to study the relationship between synthetic oxytocin augmentation and maternal blood loss, in a stratified sample. Methods: A re-analysis of a randomized controlled trial in Sweden. An on-treatment analysis was used

Patch-clamp and capacitance measurements were applied to α-, β- and δ-cells in intact mouse pancreatic islets. The maximum rate of β-cell exocytosis during a depolarization to 0 mV was 14 granules/s,

The efficient generation of isolated attosecond pulses (IAPs), giving access to ultrafast electron dynamics in various systems, is a key challenge in attosecond science. IAPs can be produced by confining the extreme ultraviolet emission generated by an intense laser pulse to a single field half-cycle or, as shown recently, by employing angular streaking methods. Here, we experimentally demonstrate

Previous studies on autobiographical memory have focused on unimodal retrieval cues (i.e., cues pertaining to one modality). However, from an ecological perspective multimodal cues (i.e., cues pertaining to several modalities) are highly important to investigate. In the present study we investigated age distributions and experiential ratings of autobiographical memories retrieved with unimodal and

The performance of hybrid solar cells composed of polymer and ZnO is mainly hindered by the defects of ZnO. Here, we investigate the effects of ZnO nanoparticle surface modification with poly(ethylene oxide) (PEO) on the performance of bulk heterojunction hybrid solar cells based on poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene] (MEH-PPV) and ZnO nanoparticles.
