An upgrade of the electronic system for frequency stabilization of the HeNe laser, primary length standard of Republic of Serbia, based on digital electronics, is described. Arduino microcontrollers have been used for stabilization, and laptop computer has been used only to communicate with the user. In addition, an analog electronics has been developed in order to boost the performance of the setup. The setup is simple and inexpensive, made of off-the-shelf electronics components. Despite this, good performances have been achieved.

AxonFinder: Automated segmentation of tumor innervating neuronal fibers.

January 2025
Cancer Early Detection Advanced Research Center (CEDAR), Knight Cancer Institute, Oregon Health and Science University, Portland, OR, USA.
Neurosignaling is increasingly recognized as a critical factor in cancer progression, where neuronal innervation of primary tumors contributes to the disease's advancement. This study focuses on segmenting individual axons within the prostate tumor microenvironment, which have been challenging to detect and analyze due to their irregular morphologies. We present a novel deep learning-based approach for the automated segmentation of axons, AxonFinder, leveraging a U-Net model with a ResNet-101 encoder, based on a multiplexed imaging approach.

Introduction: Nonfunctioning pancreatic neuroendocrine tumors (NF-PNETs) have been diagnosed increasingly often but still represent rare pancreatic neoplasms. Surgery is a potentially curative approach for patients with NF-PNETs. In recent years, minimally invasive surgery (MIS) has been applied more frequently for surgical resection of NF-PNETs.

Background: Deep sternal wound infection (DSWI) is a severe and life-threatening complication following cardiovascular surgery. Negative pressure wound therapy (NPWT) has emerged as a promising therapeutic bridging option for DSWI. In this systematic review and meta-analysis, the authors aimed to evaluate the impact of NPWT on clinical outcomes in patients with DSWI.

BMJ Open

Introduction: Little is known about the effectiveness and safety of oxygen saturation (SpO2) thresholds in children admitted with respiratory distress. The current 90%-94% threshold could lead to prolonged administration of supplemental oxygen, increased duration of hospital admissions, distress for children and families, and healthcare costs. To balance reducing unnecessary oxygen administration and preventing hypoxia, a lower SpO2 threshold of 88% for oxygen supplementation in children has been suggested.
