Population based study of prognostic factors and treatment in adult Burkitt lymphoma: a Swedish Lymphoma Registry study.

Burkitt lymphoma (BL) is a rare neoplasm constituting 1-2% of adult lymphomas. Our aims in this study were to establish prognostic factors for overall survival in adult BL and evaluate the efficacy of different chemotherapy regimens in a population based setting. The study population was collected from the Swedish Lymphoma Registry 2000-2010. During this period, 156 adult patients with BL were ide

Does canopy mean nitrogen concentration explain variation in canopy light use efficiency across 14 contrasting forest sites?

The maximum light use efficiency (LUE = gross primary production (GPP)/absorbed photosynthetic photon flux density (aPPFD)) of plant canopies has been reported to vary spatially and some of this variation has previously been attributed to plant species differences. The canopy nitrogen concentration [N] can potentially explain some of this spatial variation. However, the current paradigm of the N-e

Mutations in CEP57 cause mosaic variegated aneuploidy syndrome

Using exome sequencing and a variant prioritization strategy that focuses on loss-of-function variants, we identified biallelic, loss-of-function CEP57 mutations as a cause of constitutional mosaic aneuploidies. CEP57 is a centrosomal protein and is involved in nucleating and stabilizing microtubules. Our findings indicate that these and/or additional functions of CEP57 are crucial for maintaining

Visualization and manipulation of microRNA in neural cells

microRNA (miRNA) are small non-coding RNA, 21-23 nucleotides long. miRNA provide a new layer of regulatory control over gene expression programs. It is increasingly evident that miRNA are cell type and tissue specific. Many miRNAs have been identified to be highly abundant in certain regions of the brain. It has also been shown that alterations in levels of specific miRNAs have implications in var

Distinct cognitive effects and underlying transcriptome changes upon inhibition of individual miRNAs in hippocampal neurons.

MicroRNAs (miRNA) are small, non-coding RNAs mediating post-transcriptional regulation of gene expression. miRNAs have recently been implicated in hippocampus-dependent functions such as learning and memory, although the roles of individual miRNAs in these processes remain largely unknown. Here, we achieved stable inhibition using AAV-delivered miRNA sponges of individual, highly expressed and bra

Tooth loss and cognitive functions among older adults

Objective. To evaluate the association between the number of teeth and cognitive functions adjusted for age and education level in a cohort of older adults living in Sweden. Materials and methods. The study employed a cross-sectional design in which 1147 individuals between 60-96 years underwent a clinical oral examination. The cognitive functions were assessed using Mini-Mental State Examination

Loss of low molecular weight dissolved organic carbon (DOC) and nitrogen (DON) in H2O and 0.5 M K2SO4 soil extracts

Soil extracts are routinely used to quantify dissolved organic nutrient concentrations in soil. Here we studied the loss and transformation of low molecular weight (LMW) components of DOC (C-14-glucose, 1 and 100 mu M) and DON (C-14-amino acid mixture, 1 and 100 mu M) during extraction of soil (0-6 h) with either distilled water or 0.5 M K2SO4. The extractions were performed at 20 degrees C, at 4

Graphics processing units for handhelds

During the past few years, mobile phones and other handheld devices have gone from only handling dull text-based menu systems to, on an increasing number of models, being able to render high-quality three-dimensional graphics at high frame rates. This paper is a survey of the special considerations that must be taken when designing graphics processing units (GPUs) on such devices. Starting off by

Retinitis pigmentosa: rapid neurodegeneration is governed by slow cell death mechanisms

For most neurodegenerative diseases the precise duration of an individual cell's death is unknown, which is an obstacle when counteractive measures are being considered. To address this, we used the rd1 mouse model for retinal neurodegeneration, characterized by phosphodiesterase-6 (PDE6) dysfunction and photoreceptor death triggered by high cyclic guanosinemono-phosphate (cGMP) levels. Using cell

Comparison of wavefront sensor models for simulation of adaptive optics

The new generation of extremely large telescopes will have adaptive optics. Due to the complexity and cost of such systems, it is important to simulate their performance before construction. Most systems planned will have Shack-Hartmann wavefront sensors. Different mathematical models are available for simulation of such wavefront sensors. The choice of wavefront sensor model strongly influences c

Vibrations in Lightweight Buildings - Perception and Prediction

When the Swedish construction code (in 1994) allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, and also because wood is a plentiful resource in Sweden. Drawbacks in such buildings are disturbing vibrations and noise propagating in the construction, especially through junctions. In lightweight constr

Enhanced ROCK1 dependent contractility in fibroblast from chronic obstructive pulmonary disease patients

Background: During wound healing processes fibroblasts account for wound closure by adopting a contractile phenotype. One disease manifestation of COPD is emphysema which is characterized by destruction of alveolar walls and our hypothesis is that fibroblasts in the COPD lungs differentiate into a more contractile phenotype as a response to the deteriorating environment. Methods: Bronchial (centra

Law, objectives of government and regimes of truth: Foucault’s understanding of law and the transformation of the law of the EU internal market

Drawing on Security, Territory, Population and The Birth of Biopolitics, this article aims, firstly, to consolidate our understanding of Foucault’s engagement with law by fleshing out his approach to law and by clarifying that he distinguishes between different kinds of law on the basis of the objectives that law serves and the regime of truth that it embodies. Secondly, using this understanding,

A Mathematical Model for Interpretable Clinical Decision Support with Applications in Gynecology

Background: Over time, methods for the development of clinical decision support (CDS) systems have evolved from interpretable and easy-to-use scoring systems to very complex and non-interpretable mathematical models. In order to accomplish effective decision support, CDS systems should provide information on how the model arrives at a certain decision. To address the issue of incompatibility betwe

A Novel Framework for Storage, Analysis and Integration through Mediation of Large-scale Electrophysiological Data

We present a framework based on object orientation with novel principles for how to store, analyze and integrate electrophysiological data. These principles are: (I) Using a Decorator pattern for storing analysis data in an object model, (II) using a Core Classes data structure for integration through mediation in a service bus architecture, and (III) choosing the single unit as the finest structu
