Evaluation of Activated Carbon and Platinum Black as High-Capacitance Materials for Platinum Electrodes.

The application of direct current (DC) produces a rapid and reversible nerve conduction block. However, prolonged injection of charge through a smooth platinum electrode has been found to cause damage to nervous tissue. This damage can be mitigated by incorporating high-capacitance materials (HCM) (e.

The Stroke Preclinical Assessment Network: Rationale, Design, Feasibility, and Stage 1 Results.

Cerebral ischemia and reperfusion initiate cellular events in brain that lead to neurological disability. Investigating these cellular events provides ample targets for developing new treatments. Despite considerable work, no such therapy has translated into successful stroke treatment.

Analysis of a Cancer Stem Cell-Derived Single Colony Raised in a Microwell Array.

Cancer stem cells (CSCs) were reported to play important roles in cancer initialization, progression, and metastasis. In order to study the variation between CSCs and non-CSCs, single-cell analysis is conducted but technically complicated. In the current work, a microwell array made by an agarose hydrogel was developed for the study of a CSC-derived single colony.

User-Centered Design Process of an mHealth App for Health Professionals: Case Study.

Background: User-centered design processes are infrequently employed and not fully explored for building mobile health (mHealth) apps that are particularly targeted to health professionals as end users. The authors have used a user-centered design-based approach to build an mHealth app for health professionals, tasked to deliver medical laboratory-related information on a daily basis.

Objective: Our objective is to generate a simple and functional user-centered design process for mHealth apps for health professionals.

Visualization and Quantification of 3D Tumor Cell Migration under Extracellular Stimulation.

To investigate tumor cell migration capability, the scratch/wound healing assay and the Transwell assay are the most commonly used assays in the current biomedical research laboratory. However, both assays have their limitations and may mislead the interpretation of the results. In the current study, visualization and quantification of tumor cell migration process was realized in a three-dimensional (3D) environment.

Investigation of uniform sized multicellular spheroids raised by microwell arrays after the combined treatment of electric field and anti-cancer drug.

Nowadays, cancer disease is continuously identified as the leading cause of mortality worldwide. Cancer chemotherapeutic agents have been continuously developing to achieve high curative effectiveness and low side effects. However, solid tumors present the properties of low drug penetration and resistance of quiescent cells.

Proliferation arrest, selectivity, and chemosensitivity enhancement of cancer cells treated by a low-intensity alternating electric field.

Elimination of serious side effects is a desired feature of cancer therapy. Alternating electric field treatment is one approach to the non-invasive treatment of cancer. The efficacy and safety of this novel therapy are confirmed for the treatment of glioblastoma multiforme.
