Hyperbaric Oxygen Therapy as adjunctive treatment of chronic diabetic foot ulcers

Popular Abstract in Swedish Diabetes relaterade fotsår är en vanlig och allvarlig komplikation till diabetes. Orsaken till fotsår är mångfasetterad och inkluderar bland annat diabetesrelaterade nervskador och försämrad funktion i stora och små blodkärl. Vid förekomst av högt blodsocker fungerar immunförsvaret sämre och problematiska infektioner är vanligare vid diabetes. Sårläkning försämras vid lChronic diabetic foot ulcers are a source of major concern for both patients and health care systems. Oxygen deficiency plays a major role in the pathogenesis of these ulcers. Hyperbaric oxygen therapy (HBOT) has been proposed as a medical treatment for diabetic foot ulcers, but the clinical utility has not been established. Hyperbaric Oxygen in Diabetic patients with chronic Foot Ulcer (HODFU) st

A new approach to disease-modifying drug trials in Parkinson's disease

Translating new findings in the laboratory into therapies for patients is a slow and expensive process. The development of therapies for neurodegenerative diseases is further complicated by the difficulty in determining whether the drug truly retards the slow degenerative process or provides only symptomatic benefit. In this issue, Aviles-Olmos et al. describe a first in Parkinson's disease (PD) p

Innovation: Exploring the knowledge base

New types of knowledge, and new ways of organising the production of it, may emerge as knowledge producers respond to the challenges posed by a changing society. This paper focuses on the core knowledge of one such emerging field, namely, innovation studies. To explore the knowledge base of the field, a database of references in scholarly surveys of various aspects of innovation, published in "han

Beyond α-synuclein transfer: pathology propagation in Parkinson's disease.

α-Synuclein (α-syn) is the most abundant protein found in Lewy bodies, a hallmark of Parkinson's disease (PD), and can aggregate to form toxic oligomers and fibrillar structures. Recent studies have shown that α-syn can be transmitted between neurons and can seed the formation of toxic aggregates in recipient neurons in a prion-like manner. In addition, it is known that Lewy body pathology may spr

Models from experiments: combinatorial drug perturbations of cancer cells

We present a novel method for deriving network models from molecular profiles of perturbed cellular systems. The network models aim to predict quantitative outcomes of combinatorial perturbations, such as drug pair treatments or multiple genetic alterations. Mathematically, we represent the system by a set of nodes, representing molecular concentrations or cellular processes, a perturbation vector

Experimentally induced habitat filtering in marine bacterial communities

We tested the habitat filtering hypothesis by measuring the phylogenetic structure in marine bacterial communities before and after experimentally induced stress. The habitat filtering hypothesis predicts that phylogenetic clustering (mean relatedness) should increase as the environment becomes suitable for only a subset of the original community. We show that community composition and phylogeneti

Strengthening of timber structures with glued-in rods

The research and development of connecting and strengthening timber structural elements with glued-in rods (GiR) has been ongoing since the 1980s. Despite many successful applications in practice, agreement regarding design criteria has not been reached. This state-of-the-art review summarises results from both research and practical applications regarding connections and reinforcement with GiR. T

Forming the cores of giant planets from the radial pebble flux in protoplanetary discs

The formation of planetary cores must proceed rapidly in order for the giant planets to accrete their gaseous envelopes before the dissipation of the protoplanetary gas disc (less than or similar to 3 Myr). In orbits beyond 10 AU, direct accumulation of planetesimals by the cores is too slow. Fragments of planetesimals could be accreted faster, but planetesimals are likely too large for fragmentat

Conodont biostratigraphy in the Early to Middle Ordovician strata of the Oslobreen Group in Ny Friesland, Svalbard

The remotely located Cambro-Ordovician strata in Ny Friesland, NE Spitsbergen, Svalbard, are referred to the Oslobreen Group, which is composed of the Tokammane, Kirtonryggen and Valhallfonna formations. Herein we record the conodont succession of the Kirtonryggen and Valhallfonna formations. Collections of well-preserved conodonts (CAI 1) have been recovered from the Lower to lower Middle Ordovic

A 9-year follow-up study of participants and nonparticipants in sigmoidoscopy screening: Importance of self-selection

Background: Self-selection may compromise cost-effectiveness of screening programs. We hypothesized that nonparticipants have generally higher morbidity and mortality than participants. Methods: A Swedish population-based random sample of 1,986 subjects ages 59 to 61 years was invited to sigmoidoscopy screening and followed up for 9 years by means of multiple record linkages to health and populati

Practical Recommendations for Measuring Rates of Visual Field Change in Glaucoma

Statement of Interest Assessment of visual field damage is the major index of the functional impact of glaucoma with direct relevance to quality of life measures. Visual field change was used as a primary endpoint for progression in the recent glaucoma trials and its measurement is the cornerstone of glaucoma management influencing therapeutic decisions. The objective of this perspective is to pro

The association between the North Atlantic oscillation and the interannual variability of the tropospheric transport pathways in Western Europe

The variations in tropospheric transport pathways over a 20 year period, 1990-2009, are studied at six locations in Europe. Three Atlantic (Lisbon, Mace Head, and Cabauw) and three Mediterranean sites (Malaga and Elche in the western part and Lecce in the central Mediterranean) are considered. The work is based on the identification of flow types at each location by robust cluster analysis of the

MafA and MafB Regulate Genes Critical to beta-Cells in a Unique Temporal Manner

OBJECTIVE-Several transcription factors are essential to pancreatic islet beta-cell development, proliferation, and activity, including MafA and MafB. However, MafA and MafB are distinct from others in regard to temporal and islet cell expression pattern, with beta-cells affected by MafB only during development and exclusively by MafA in the adult. Our aim was to define the functional relationship

NCN concentration and interfering absorption by CH2O, NH and OH in low pressure methane/air flames with and without N2O

Absorption spectra in the wavelength region around 329 nm have been recorded with the cavity ring-down technique in various low pressure (200 hPa) CH4/air flames, two of which with N2O (nitrous oxide) addition. NCN (cyanonitrene) absorption appears to be significant only in N2O-enriched flames, which also reveal spectrally nearby absorption by NH. In a phi = 1.14, N2O oxidizer volume fraction = 57
