This report details the development of a non-invasive in vitro assay system for investigating the functional maturation and performance of human skeletal myotubes. Data is presented demonstrating the survival and differentiation of human myotubes on microscale silicon cantilevers in a defined, serum-free system. These cultures can be stimulated electrically and the resulting contraction quantified using modified atomic force microscopy technology. This system provides a higher degree of sensitivity for investigating contractile waveforms than video-based analysis, and represents the first system capable of measuring the contractile activity of individual human muscle myotubes in a reliable, high-throughput and non-invasive manner. The development of such a technique is critical for the advancement of body-on-a-chip platforms toward application in pre-clinical drug development screens.

Microfluidic impedance cytometry (MIC) is a label-free technique that characterizes individual flowing particles/cells based on their interaction with a multifrequency electric field. The technique has been successfully applied in different scenarios including life-science research, diagnostics, and environmental monitoring. The aim of this review is to illustrate the fascinating opportunities enabled by the integration of MIC with other microfluidic tools.

Here, we found that PMA1 expression was significantly increased in from patients with IBD compared to that in healthy controls. A Crispr-Cas9-based fungal strain editing system was then used to knock out PMA1 expression in .

Background: Over the past decade, there has been a significant shift from paper-based to digital medical record management, driven largely by advances in digital technology. This transition has led to widespread adoption of Electronic Medical Records (EMRs), with the expectation that paper documentation will soon be fully replaced. In response, the European Medicines Agency's "Guideline on Computerised Systems in Clinical Trials" outlines essential criteria for validated EMR systems to ensure data integrity and security, and sets standards for electronic source documents in clinical trials.

Background: Streptococcal Toxic Shock Syndrome (STSS) is a life-threatening condition caused by bacterial toxins. The STSS triad encompasses high fever, hypotensive shock, and a "sunburn-like" rash with desquamation. STSS, like Toxic Shock Syndrome (TSS), is a rare complication of streptococcal infec-tions caused by Group A Streptococcus (GAS), Streptococcal pyogenes (S.
