A novel salt-barrier method of preparation flexible temperature resistant full-component nanocellulose membranes.

With the simplification and diversification of separation technologies, nanocellulose membranes have become widely used as insulating materials. Recently, study of nanocellulose membrane modification has become a hot topic. However, the application of nanocellulose membrane has been limited due to their inadequate heat resistance and flexibility.

Clinical feasibility of the augmented reality computer-assisted spine surgery system for percutaneous vertebroplasty.

Purpose: This study aimed to demonstrate that the augmented reality computer-assisted spine surgery (ARCASS) system is clinically feasible for percutaneous vertebroplasty (PVP).

Methods: This prospective case-control study included the patients undergoing PVP under the assistance of the ARCASS system between July 1, 2013, and October 31, 2014. The control group was the age- and gender-matched patients who underwent standard PVP and met the same eligible criteria as the case group.

Improving Discrimination in Color Vision Deficiency by Image Re-Coloring.

People with color vision deficiency (CVD) cannot observe the colorful world due to the damage of color reception nerves. In this work, we present an image enhancement approach to assist colorblind people to identify the colors they are not able to distinguish naturally. An image re-coloring algorithm based on eigenvector processing is proposed for robust color separation under color deficiency transformation.

HOPIS: hybrid omnidirectional and perspective imaging system for mobile robots.

In this paper, we present a framework for the hybrid omnidirectional and perspective robot vision system. Based on the hybrid imaging geometry, a generalized stereo approach is developed via the construction of virtual cameras. It is then used to rectify the hybrid image pair using the perspective projection model.

Real-time advanced spinal surgery via visible patient model and augmented reality system.

This paper presents an advanced augmented reality system for spinal surgery assistance, and develops entry-point guidance prior to vertebroplasty spinal surgery. Based on image-based marker detection and tracking, the proposed camera-projector system superimposes pre-operative 3-D images onto patients. The patients' preoperative 3-D image model is registered by projecting it onto the patient such that the synthetic 3-D model merges with the real patient image, enabling the surgeon to see through the patients' anatomy.

A chirality indicator for the surfaces of the silica nanotubes.

The chirality of the silicas attracted much attention, due to their potential applications in asymmetric catalysis and enantioseparation. However, their chirality has not been well understood. Herein, a chirality indicator for the surfaces of the silica nanotubes was developed.

Simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach.

Laparoscopic resection of rectal cancer or gastric cancer has been advocated for the benefits of a reduced morbidity, a shorter treatment time, and similar outcomes. However, simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach are rarely documented in literature. Endoscopic examination revealed a synchronous carcinoma of rectum and stomach in a 55-year-old male patient with rectal bleeding and epigastric discomfort.

Hyperthermic CO2 pneumoperitoneum induces apoptosis in human colon cancer cells through Bax-associated mitochondrial pathway.

Peritoneal carcinomatosis of colorectal cancer is common and associated with poor prognosis, which poses a serious challenge and satisfactory treatments are urgently needed. Hyperthermic CO2 pneumoperitoneum (HT-CO2) is a new strategy. This study was designed to determine the potential of HT-CO2 against colorectal cancer cells.
