Local delivery of TGF-β1-mRNA decreases fibrosis in osteochondral defects.

Osteoarthritis (OA) is a condition that affects the quality of life of millions of patients worldwide. Current clinical treatments, in most cases, lead to cartilage repair with deposition of fibrocartilage tissue, which is mechanically inferior and not as durable as hyaline cartilage tissue. We designed an mRNA delivery strategy to enhance the natural healing potential of autologous bone marrow aspirate concentrate (BMAC) for articular cartilage repair.

Arthrodesis Versus Ligament Reconstruction and Tendon Interposition for Thumb Carpometacarpal Joint Arthritis: A Systematic Review and Meta-Analysis.

Purpose: Arthrodesis and ligament reconstruction and tendon interposition (LRTI) are commonly performed procedures for treatment of thumb carpometacarpal (CMC) osteoarthritis. Although LRTI is the most common surgical treatment, CMC arthrodesis has been performed because of its reported advantages. This systematic review and meta-analysis compared the differences between CMC arthrodesis and LRTI to better inform surgeons and patients when they are making treatment decisions.

Neural network-based automated proptosis measurement using computed tomography images for patients with thyroid-associated orbitopathy.

The purpose of this study was to evaluate the clinical feasibility and reliability of a neural network (NN)-based automated proptosis measurement system using computed tomography (CT) images. An automated proptosis measurement system was developed using the CT images of 200 eyes from 100 patients diagnosed with thyroid-associated orbitopathy. We compared the proptosis value obtained from the proposed automated system with the values obtained from the Hertel exophthalmometer and manual measurements of CT slices.

Effective encoder-decoder network for pupil light reflex segmentation in facial photographs of ptosis patients.

Accurate segmentation of pupil light reflexes is essential for the reliable assessment of ptosis severity, a condition characterized by the drooping of the upper eyelid. This study introduces a novel encoder-decoder network specialized in reflex segmentation by focusing on addressing issues related to very small regions of interest from an architectural perspective. Specifically, the proposed network is designed to exploit low-level features effectively by integrating a multi-level skip connection and a 1 × 1 convolution-enhanced initial encoding stage.

NEGR1 Modulates Mouse Affective Discrimination by Regulating Adult Olfactory Neurogenesis.

Background: Affective recognition and sensory processing are impaired in people with autism. However, no mouse model of autism comanifesting these symptoms is available, thereby limiting the exploration of the relationship between affective recognition and sensory processing in autism and the molecular mechanisms involved.

Methods: With mice, we conducted the affective state discrimination test and an odor habituation/dishabituation test.

Automated eyeball volume measurement based on CT images using neural network-based segmentation and simple estimation.

With the increase in the dependency on digital devices, the incidence of myopia, a precursor of various ocular diseases, has risen significantly. Because myopia and eyeball volume are related, myopia progression can be monitored through eyeball volume estimation. However, existing methods are limited because the eyeball shape is disregarded during estimation.

RicePilaf: a post-GWAS/QTL dashboard to integrate pangenomic, coexpression, regulatory, epigenomic, ontology, pathway, and text-mining information to provide functional insights into rice QTLs and GWAS loci.

Background: As the number of genome-wide association study (GWAS) and quantitative trait locus (QTL) mappings in rice continues to grow, so does the already long list of genomic loci associated with important agronomic traits. Typically, loci implicated by GWAS/QTL analysis contain tens to hundreds to thousands of single-nucleotide polmorphisms (SNPs)/genes, not all of which are causal and many of which are in noncoding regions. Unraveling the biological mechanisms that tie the GWAS regions and QTLs to the trait of interest is challenging, especially since it requires collating functional genomics information about the loci from multiple, disparate data sources.

A Novel Multiobjective Genetic Programming Approach to High-Dimensional Data Classification.

The development of data sensing technology has generated a vast amount of high-dimensional data, posing great challenges for machine learning models. Over the past decades, despite demonstrating its effectiveness in data classification, genetic programming (GP) has still encountered three major challenges when dealing with high-dimensional data: 1) solution diversity; 2) multiclass imbalance; and 3) large feature space. In this article, we have developed a problem-specific multiobjective GP framework (PS-MOGP) for handling classification tasks with high-dimensional data.

Five Low-Noise Stable Oscillators Referenced to the Same Multimode AlN/Si MEMS Resonator.

We report on the first experimental demonstration of five self-sustaining feedback oscillators referenced to a single multimode resonator, using piezoelectric aluminum nitride on silicon (AlN/Si) microelectromechanical systems (MEMS) technology. Integrated piezoelectric transduction enables efficient readout of five resonance modes of the same AlN/Si MEMS resonator, at 10, 30, 65, 95, and 233 MHz with quality ( Q ) factors of 18 600, 4350, 4230, 2630, and 2138, respectively, at room temperature. Five stable self-sustaining oscillators are built, each referenced to one of these high- Q modes, and their mode-dependent phase noise and frequency stability (Allan deviation) are measured and analyzed.

Sexual Dimorphism in the Mechanism of Pain Central Sensitization.

It has long been recognized that men and women have different degrees of susceptibility to chronic pain. Greater recognition of the sexual dimorphism in chronic pain has resulted in increasing numbers of both clinical and preclinical studies that have identified factors and mechanisms underlying sex differences in pain sensitization. Here, we review sexually dimorphic pain phenotypes in various research animal models and factors involved in the sex difference in pain phenotypes.
