AI Article Synopsis
- A new ultrasonic device was developed to improve measurement accuracy during neurosurgery, particularly for tumor removal, by eliminating the need for saline application and reducing subjectivity.
- The study involved comparing two types of ultrasound devices through both ex vivo experiments and human surgeries, demonstrating high correlation in measuring tumor depth and tissue thickness.
- Results showed that the new device offers objective, real-time monitoring capabilities, enhancing surgical precision in challenging conditions and proving to be more reliable than the conventional ultrasonic imaging systems.
Article Abstract
Background: Applying ultrasonic imaging system during surgery requires the poring of saline, performing the measurement, and acquiring data from its display-which requires time and is highly "performer dependent," i.e., the measure is of a subjective nature. A new ultrasonic device was recently developed that overcomes most of these drawbacks and was successfully applied during tumor-in-brain neurosurgeries. The purpose of this study was to compare the two types of US devices and demonstrate their properties.
Methods: The study was performed in the following stages: (i) an ex vivo experiment, where slices of the muscle and brain of a young porcine were laid one on top the other. Thicknesses and border depths were measured and compared, using the two types of US instruments. (ii) During human clinical neurosurgeries, tumor depth was compared by measuring it with both devices. (iii) Following the success of stages (i) and (ii), using solely the new US device, the tumor thickness was monitored while its resection.Correlation, Pearson's coefficient, average, mean, and standard deviation were applied for statistical tests.
Results: A high correlation was obtained for the distances of tissue borders and for their respective thicknesses. Applying these ultrasonic devices during neurosurgeries, tumor depths were monitored with high similarity (87%), which was also obtained by Pearson's correlation coefficient (0.44). The new US device, thanks to its small footprint, its remote measurement, and the capability of monitoring intraoperatively and in real-time, provides the approach to tumor's border before its complete resection.
Conclusions: The new US device provides better accuracy than an ultrasonic imaging system; its data is objective; it enables to the residual tumor thickness during its resection, and it is especially useful in restricted areas. These features were found of great help during a tumor-in-brain surgery and especially in the final stages of tumor's resection.

In this study, we have investigated the surface-enhanced Raman scattering (SERS) spectra of myoglobin on silver substrates with different morphology. The aim was to determine the optimal parameters of analyte and substrate preparation for obtaining of high-amplitude SERS spectra of proteins. It is shown that not only the morphology of the silver film, but also the method of analyte molecules deposition on the SERS substrate plays an important role.

In the growing field of personalized medicine, non-invasive wearable devices and sensors are valuable diagnostic tools for the real-time monitoring of physiological and biokinetic signals. Among all the possible multiple (bio)-entities, pH is important in defining health-related biological information, since its variations or alterations can be considered the cause or the effect of disease and disfunction within a biological system. In this work, an innovative (bio)-electrochemical flexible pH sensor was proposed by realizing three electrodes (working, reference, and counter) directly on a polyimide (Kapton) sheet through the implementation of CO laser writing, which locally converts the polymeric sheet into a laser-induced graphene material (LIG electrodes), preserving inherent mechanical flexibility of Kapton.
