The limit of validity of linear fracture mechanics is specified by the minimum allowable crack length through an ASTM convention. Extension into the non-linear region ought to imply an extension towards smaller allowable Cracks. In order to elucidate the question "How short is the smallest crack that fits the methods of fracture mechanics, and how do shorter cracks than that behave?" a pilot inves

In this review we summarize the events known to occur after an injury in the peripheral nervous system. We have focused on the Schwann cells, as they are the most important cells for the repair process and facilitate axonal outgrowth. The environment created by this cell type is essential for the outcome of the repair process. The review starts with a description of the current state of knowledge

A nerve injury has a profound impact on the patient's daily life due to the impaired sensory and motor function, impaired dexterity, sensitivity to cold as well as eventual pain problems. To perform an appropriate treatment of nerve injuries, a correct diagnosis must be made, where the injury is properly classified, leading to an optimal surgical approach and technique, where timing of surgery is

Background: Hand injuries occur at all ages. With an aging population globally an increasing number of hand injuries among the elderly is to be expected. The aim of the present study is to describe the health characteristics and detailed injury patterns for elderly with hand injuries, with incidence, as a background for further studies on the topic. Specific knowledge is currently lacking about ha

Studies of crack behaviour and fracture are generally performed using continuum analysis. Thus, the process region is either not considered at all or assumed to be point-sized. In the latter case it is often ascribed a desired property, usually the ability to consume energy.A major step towards the understanding of the fracture process region the concept of autonomy of the near tip field was intro

The development of gut microbiota during ontogeny is emerging as an important process influencing physiology, immunity and fitness in vertebrates. However, knowledge of how bacteria colonize the juvenile gut, how this is influenced by changes in the diversity of gut bacteria and to what extent this influences host fitness, particularly in nonmodel organisms, is lacking. Here we used 16S rRNA gene

Aim: To describe the Swedish Neonatal Quality Register (SNQ) and to determine its completeness and agreement with other registers. Methods: SNQ collects data for infants admitted to neonatal units during the first four postnatal weeks. Completeness and registers’ agreement were determined cross-linking SNQ data with Swedish population registers (the Inpatient, Medical Birth and Cause of Death Regi

Background and aims: Unstable carotid atherosclerosis causes stroke, but methods to identify patients and lesions at risk are lacking. We recently found enrichment of genes associated with calcification in carotid plaques from asymptomatic patients. Here, we hypothesized that calcification represents a stabilising feature of plaques and investigated how macro-calcification, as estimated by compute
