Questioning the role of sparse coding in the brain.

Coding principles are central to understanding the organization of brain circuitry. Sparse coding offers several advantages, but a near-consensus has developed that it only has beneficial properties, and these are partially unique to sparse coding. We find that these advantages come at the cost of several trade-offs, with the lower capacity for generalization being especially problematic, and the

Chromosome 9p21 genetic variation explains 13% of cardiovascular disease incidence but does not improve risk prediction.

OBJECTIVES: To evaluate the proportion of cardiovascular disease (CVD) incidence that is explained by genetic variation at chromosome 9p21 and to test whether such variation adds incremental information with regard to CVD prediction, beyond traditional risk factors. DESIGN, SETTING AND PARTICIPANTS: rs4977574 on chromosome 9p21 was genotyped in 24 777 subjects from the Malmö Diet and Cancer study

Using albumin to improve the therapeutic properties of diabetes treatments.

Achieving tight glycaemic control remains an unmet need for many patients with type 2 diabetes, despite improved treatments. In order to meet glycaemic targets, attempts have been made to improve existing drugs and to develop new classes of drugs. Recent advances include insulin analogues that more closely mimic physiologic insulin levels, and incretin-based therapies, which capitalise on the gluc

How Can Movement Quality Be Promoted in Clinical Practice? A Phenomenological Study of Physical Therapist Experts

Background. In recent years, physical therapists have paid greater attention to body awareness. Clinicians have witnessed the benefits of supporting their patients' learning of movement awareness through the promotion of their movement quality. Objective. The aim of this study was to investigate how physical therapist experts promote movement quality in their usual clinical settings. Design. A phe

A new system for naming ribosomal proteins.

A system for naming ribosomal proteins is described that the authors intend to use in the future. They urge others to adopt it. The objective is to eliminate the confusion caused by the assignment of identical names to ribosomal proteins from different species that are unrelated in structure and function. In the system proposed here, homologous ribosomal proteins are assigned the same name, regard

The antimicrobial peptide LL-37 is anti-inflammatory and proapoptotic in human periodontal ligament cells.

The antimicrobial peptide LL-37 is anti-inflammatory and proapoptotic in human periodontal ligament cells. J Periodont Res 2011; doi: 10.1111/j.1600-0765.2011.01436.x. © 2011 John Wiley & Sons A/S Background and Objective: The antimicrobial peptide LL-37 is expressed in periodontal tissue, and variations in LL-37 levels have been associated with periodontal disease. The effects of LL-37 on per

Practical Design and Performance Based Regulations

The paper presents a sample design of a multi-storey building with respect to the fire safety. Three design strategies are examined, a standard solution according to the requirements, a fire safety engineering design without a sprinkler system and finally a fire safety engineering design with a sprinkler system. The objective was to demonstrate different design strategies and still comply with the

Trend analysis of Icelandic discharge, precipitation and temperature series.

This study is a part of a Nordic co-operative research project, Climate and Energy, funded by Nordic Energy Research and the Nordic energy sector. The project has the objective of a comprehensive assessment of the impact of climate change on Nordic renewable energy resources including hydropower, wind power, biofuels and solar energy. In this paper, the long term variability of precipitation, temp

Economic Policies for Healthier Food Intake: The Impact on Different Household Categories

This paper simulates the impact across household types of fully funded tax reforms designed to increase consumers’ fiber intake from grain consumption. Our results suggest that household types with the highest initial consumption share of fiber-rich products—i.e., households without children (seniors, couples without children, and single women without children)—experience the highest increase in f

MicroRNAs in the failing heart - Novel therapeutic targets?

Abstract Heart failure is a common and disabling disease with high mortality that carries substantial societal costs. Current therapeutic strategies are aimed at relieving symptoms, avoiding hospitalization, and prolonging life, but disease progression is ultimately inevitable. MicroRNAs (miRNAs) are short, non-coding RNA molecules with pervasive roles in eukaryotic biology, annealing to complimen

WNT5A-mediated β-catenin-independent signalling is a novel regulator of cancer cell metabolism.

WNT5A has been identified as an important ligand in the malignant progression of a number of tumours. Although WNT5A signalling is often altered in cancer, the ligand's role as either a tumour suppressor or oncogene varies between tumour types and is a contemporary issue for investigators of β-catenin-independent WNT signalling in oncology. Here, we report that one of the initial effects of active

Simulation and parametric study of a film-coated controlled-release pharmaceutical.

Pharmaceutical formulations can be designed as Multiple Unit Systems, such as Roxiam CR, studied in this work. The dose is administrated as a capsule, which contains about 100 individual pellets, which in turn contain the active drug remoxipride. Experimental data for a large number of single pellets can be obtained by studying the release using microtitre plates. This makes it possible to study t

Physical Activity and Concordance between Objective and Perceived Walkability.

PURPOSE:: To investigate concordance between objective and perceived neighborhood walkability, their associations with self-reported walking and objective physical activity, and sociodemographic characteristics of individuals in neighborhoods with objectively assessed high walkability who misperceive it as low. METHODS:: In 1,925 individuals aged 20-66 years, recruited from administrative areas in
