Simple and low-cost microscopy setup for 3D particle field measurement using incoherent illumination and open-source hardware.

The quantification of 3D particle field is of interest for a vast range of fields. While in-line particle holography (PH) can provide high-resolution measurements of particles, it suffers from speckle noise. Plenoptic imaging (PI) is less susceptible to speckle noises, but it involves a trade-off between spatial and angular resolution, rendering images with low resolution.

Effect of opposing needling on motor cortex excitability in healthy participants and in patients with post-stroke hemiplegia: study protocol for a single-blind, randomised controlled trial.

Background: Opposing needling has an obvious curative effect in the treatment of post-stroke hemiplegia; however, the mechanism of the opposing needling in the treatment of post-stroke hemiplegia is still not clear. The purpose of this study is to investigate the effect of opposing needling on the excitability of primary motor cortex (M1) of healthy participants and patients with post-stroke hemiplegia, which may provide insight into the mechanisms of opposing needling in treating post-stroke hemiplegia.

Methods: This will be a single-blind, randomised, sham-controlled trial in which 80 healthy participants and 40 patients with post-stroke hemiplegia will be recruited.

GHz sampling hardware implementation with sub-Nyquist coprime sampling rates.

A sub-Nyquist coprime sampling system for sparse signals is implemented in this article. The proposed system is composed of coprime sampling hardware and a multicoset signal reconstruction algorithm. A pair of uniform samplers is utilized in the hardware to sample a wideband spare analog signal with an uncertain difference in start times.

Compressed sensing based sub-Nyquist sampling of multiple sinusoids with dual rate channels.

In this paper, we propose a reconstruction approach for a multiple-sinusoidal signal. The signal reconstruction requires a small number of samples and is based on a sub-Nyquist sampling scheme with dual rate channels. In the proposed sampling scheme, the samples are grouped into multiple cosets.

Clinical and radiological outcome of Gustilo type III open distal tibial and tibial shaft fractures after staged treatment with posterolateral minimally invasive plate osteosynthesis (MIPO) technique.

Objectives: To evaluate the methods and the outcomes of Gustilo type III open distal tibial and tibial shaft fractures with severe anterior and medial soft-tissue injuries, treated with posterolateral minimally invasive plate osteosynthesis (MIPO) technique.

Methods: From May 2015 to May 2016, 10 patients with Gustilo type III open distal tibial and tibial shaft fractures with severe anterior and medial soft-tissue injuries (Gustilo-Anderson classification IIIA, 6; IIIB, 4) were treated with staged protocol using posterolateral minimally invasive plate osteosynthesis (MIPO) technique. The initial wound lavage, debridement, and application of a spanning external fixator were performed within 24 h and the mean interval from injury to definitive surgical treatment was 12.

Application of pre-contoured anatomic locking plate for treatment of humerus split type greater tuberosity fractures: A prospective review of 68 cases with an average follow-up of 2.5 years.

Objectives: Although various implants exist for 3- and 4-part proximal humerus fractures, few implants are appropriate for humerus split type greater tuberosity fractures. The goal of this study was to assess the efficacy of pre-contoured anatomic locking plate for humerus split type greater tuberosity fractures.

Methods: A retrospective review of 68 patients with humerus split type greater tuberosity fractures treated with open reduction and internal fixation using anatomic locking plates between January 2014 and October 2016.

Analysis of red blood cells' dynamic status in a simulated blood circulation system using an ultrahigh-speed simultaneous framing optical electronic camera.

Alterations in the morphologic and mechanical properties of red blood cells (RBCs) are considered direct indicators of blood quality. Current measures of characterizing these properties in vivo are limited by the complicated hemodynamic environment. To better evaluate the quality of fresh and stored blood, a new research platform was constructed to evaluate the hemodynamic characteristics of RBCs.

Percutaneous cryoablation for stage IV lung cancer: a retrospective analysis.

The aim of this study was to investigate the therapeutic effect of cryoablation treatment and palliative treatment in stage IV lung cancer. Fifty-four patients were enrolled into the study. Thirty-one patients received cryoablation treatment (including intra- and extrapulmonary tumors), and 23 patients had palliative treatment (no cryoablation).
