Comparative Effects of Advanced Footwear Technology in Track Spikes and Road-Racing Shoes on Running Economy.

Purpose: Determine the effects of advanced footwear technology (AFT) in track spikes and road-racing shoes on running economy (RE).

Methods: Four racing shoes (3 AFT and 1 control) and 3 track spikes (2 AFT and 1 control) were tested in 9 male distance runners on 2 visits. Shoes were tested in a random sequence over 5-minute trials on visit 1 (7 trials at 16 km·h-1; 5-min rest between trials) and in the reverse/mirrored order on visit 2.

Lower limb revascularisation preceding surgical wound coverage - an interdisciplinary algorithm for chronic wound closure.

Background: Chronic wounds may occur or persist due to arterial insufficiency. Despite the high prevalence of arterial occlusive disease, a search of the literature has yielded a paucity of data on the benefit of interventions to recanalise lower extremity arteries prior to surgical closure of chronic wounds.

Objective: To investigate the correlation of simple clinical examinations and apparative diagnostics for the detection of arterial occlusive disease of the lower extremity in patients with chronic wounds, and to evaluate the benefit of vascular procedures to optimise wound perfusion before surgical closure.

[Vascular interventions and reconstructive plastic surgery. Optimizing the treatment of chronic wounds].

Despite the high prevalence of arterial occlusive disease, only a few studies have investigated the benefit of interventions to recanalize extremity arteries prior to plastic operations to close chronic wounds. The purpose of this study was to investigate the correlation of simple clinical examinations and apparative diagnostics of arterial occlusive disease of the lower extremity in patients with chronic wounds and to evaluate the benefit of vascular procedures to optimize wound perfusion before surgical closure. A total of 150 individuals with chronic wounds were included in this retrospective study.

A penalized likelihood approach to magnetic resonance image reconstruction.

Currently, images acquired via magnetic resonance imaging (MRI) and functional magnetic resonance imaging (fMRI) technology are reconstructed using the discrete inverse Fourier transform. While computationally convenient, this approach is not able to filter out noise. This is a serious limitation because the amount of noise in MRI and fMRI can be substantial.
