Background: Droplet microfluidics with push-pull and microdialysis sampling from brain slices, cultured cells and engineered tissues produce low volume mass limited samples containing analytes sampled from the extracellular space. This sampling approach coupled to mass spectrometry (MS) detection allows evaluation of time-dependent chemical changes. Our goal is an approach for continuous sampling and segregation of extracellular samples into picoliter droplets followed by the characterization of the droplets using nanoelectrospray ionization (nESI) MS.

Introduction: Public participation can be both supported and limited by decision-makers. Therefore, citizens either participate in top-down approved formats or have to turn towards subversion. These different participation practices, called invited and uninvited, are often treated by researchers as mutually exclusive.

Presented clinical observation of anti-NMDA-receptor encephalitis, which was first described in 2007, is rare and to date has not been sufficiently studied. The disease often manifests with psychopathological symptoms and catatonia, so patients are transferred into a mental healthcare institution and often require intensive care and resuscitation, due to the development of life-threatening respiratory and hemodynamic disorders. Diagnosis is based on detection of autoantibodies to the NR1- and NR2 subunits of the glutamate NMDA receptor in blood serum and cerebrospinal fluid.

Article Synopsis
  • Microdialysis (MD) is a key method used to analyze chemicals in biological tissues, useful in various fields like neurology and dermatology, but it faces limitations in sensitivity and resolution.
  • The development of a nanodialysis (ND) probe using advanced silicon microfabrication offers improved chemical sampling, achieving 100 μm spatial resolution and subsecond timing, significantly outperforming traditional MD techniques.
  • These ND probes can provide detailed, minimally invasive sampling in live tissues, opening up opportunities for advancements in clinical and pharmaceutical research.

Background: Spinal muscular atrophy (SMA) is a rare genetic disorder, in which, for the common childhood onset forms, loss of function of the SMA 5q gene leads to disability and death before adulthood. Symptomatic treatment focusses on respiratory and nutritional support, and physical therapy, but there is little consideration of psychiatric manifestations of SMA. The aim of this study was to explore blood biomarker levels, electromyography (EMG) data, and clinical manifestations, including psychiatric impairments, in patients with SMA 5q.
