AIMS The objective of the present study was to determine the specificity, sensitivity and accuracy of intraoral and transcutaneous ultrasound (US) in the diagnosis of peritonsillar cellulitis and abscess. STUDY DESIGN Clinical-Prospective. MATERIAL AND METHODS Thirty nine patients were seen at the otorhinolaryngology emergency department of the University Hospital, of the School of Medicine...

AIMS The aim of this prospective study was to evaluate the accuracy of transcutaneous bilirubinometry using the Minolta Air-Shields JM-103 device in preterm newborns of gestational age 32-34 weeks, and to identify the most appropriate measurement site. METHODS Transcutaneous bilirubin (TcB) measurements were performed over forehead, sternum and abdomen, if total serum bilirubin (TSB) had to b...

BACKGROUND Inulin/sinistrin (I/S) clearance is a gold standard for an accurate assessment of glomerular filtration rate (GFR). Here we describe and validate an approach for a transcutaneous determination of GFR by using fluorescein-isothiocyanate-labelled sinistrin (FITC-S) in rats. METHODS Using a small animal imager, fluorescence is measured over the depilated ear of a rat after the injecti...

OBJECTIVE To investigate whether transcutaneous electrical stimulation, when applied to acupuncture points in patients after acute stroke, decreases spasticity and/or increases muscle strength more effectively than placebo stimulation and standard rehabilitation. DESIGN Randomized control trial. SUBJECTS Sixty-two patients aged 70.0 (standard deviation 7.4) years and 9.2 (standard deviation...

Objective: Evaluate the safety and efficacy of transcutaneous vagus nerve stimulation in preventing respiratory failure improving survival hospitalized COVID-19 patients.

____________ _ Measurements of transcutaneous POz (tc POz), intraarterial P02(P;02) and P02 of blood samples taken from the sampling port of the oxygenator (PoOz) were compared with arterial blood P02 (PaOz) in 16 adult patients undergoing cardiopulmonary bypass. tcP02 and Pi02 were recorded continuously using Roche-Kontron electrodes. Po02 and PaOz were measured intermittently on a Radiometer ...

Figure 1. Recording of single neurons in the rodent hippocampal system. (A) A typical laboratory experimental setup for recording spatially sensitive neurons in exploring animals. The animals are implanted with moveable microelectrodes that are situated in the brain region of interest. The electrodes are attached to a tiny drive mechanism that allows the experimenter to advance the electrodes t...

Printed polymer electronics has held for long the promise of revolutionizing technology by delivering distributed, flexible, lightweight and cost-effective applications for wearables, healthcare, diagnostic, automation and portable devices. While impressive progresses have been registered in terms of organic semiconductors mobility, field-effect transistors (FETs), the basic building block of a...

It has been proposed that single molecules of DNA could be sequenced by measuring the physical properties of the bases as they pass through a nanopore. Theoretical calculations suggest that electron tunnelling can identify bases in single-stranded DNA without enzymatic processing, and it was recently experimentally shown that tunnelling can sense individual nucleotides and nucleosides. Here, we...

Fast hydrogen sensors based on discontinuous palladium (Pd) films on supporting polyimide layers, fabricated by a cost-efficient and full-wafer compatible process, are presented. The films, deposited by electron-beam evaporation with a nominal thickness of 1.5 nm, consist of isolated Pd islands that are separated by nanoscopic gaps. On hydrogenation, the volume expansion of Pd brings initially ...
