Announcing a new article publication for Cardiovascular Innovations and Applications journal. Aortic dissection (AD) is a fatal cardiovascular disease for which the key involved genes are largely unknown. The authors of this article aimed to identify promising AD biomarkers from high-throughput RNA expressing data.
In the GSE98770 dataset, differentially expressed mRNAs (DE-mRNAs) and microRNAs (DE-microRNAs) were identified through differentially expressed gene analysis and gene set enrichment analysis. The regulatory network between DE-mRNAs and DE-microRNAs was established, and hub genes were identified with Cytoscape. Relationships between hub genes and AD were confirmed in the Comparative Toxicogenomics Database (CTD). Potential key transcription factors were discovered with Cytoscape. Hub gene verification was performed by qPCR and immunofluorescence analyses of human specimens.
DE-mRNAs and DE-microRNAs were identified. Four mRNAs and microRNA-1321 (miR-1321) were found to have the most connections with other genes. CBL was connected to the most genes and interacted with miR-1321, which was also connected to the most genes among the DE-microRNAs. In addition, CBL was associated with AD in the CTD. Among the top five transcription factors potentially regulating CBL transcription, only HOXB13 was a DE-mRNA. The findings were further successfully verified in human specimens.
CBL, which may be transcriptionally regulated by HOXB13 and post-transcriptionally regulated by miR-1321, was identified as the most promising potential biomarker for AD.

Problem gambling may be on the rise among monthly gamblers in Massachusetts, online surveys suggest
2024-08-29
In the latest of three online gambling surveys conducted by the University of Massachusetts Amherst, monthly gamblers in Massachusetts reported an increase in gambling intensity and gambling harms. In addition, their attitudes toward gambling have grown more negative.
The online surveys – conducted in 2014, 2022 and 2023 – can’t be generalized to the overall population but give the Social and Economic Impacts of Gambling in Massachusetts (SEIGMA) research team a picture of changing behaviors and attitudes over time ...

NEC Society recognizes a decade of impact
2024-08-29
Davis, CA — The NEC Society, a nonprofit organization dedicated to preventing necrotizing enterocolitis (NEC), a devastating neonatal intestinal disease, proudly marks its 10th anniversary. Founded by Jennifer Canvasser after the tragic loss of her son, Micah, the organization works tirelessly to build a world without NEC, the disease that killed her child and claims another child every day in the United States.
Canvasser shares, "Ten years ago, patient-families affected by NEC were isolated, and clinician-scientists worked in silos. Over the past decade, we've built an empowered community dedicated to transforming our pain into power and isolation into collaboration.”

Analysis shows how unproven therapeutics were portrayed in the media during the early phase of COVID-19 pandemic
2024-08-29
WINSTON-SALEM, N.C. – Aug. 29, 2024 – A new study from researchers at Wake Forest University School of Medicine is shedding light on how scientific evidence and the uncertainty surrounding three unproven therapeutics were portrayed by the U.S. news media during the early days of the COVID-19 pandemic.
The findings appear online in the Journal of Medical Internet Research Infodemiology.
For the study, the researchers conducted an analysis of 479 reports of hydroxychloroquine, remdesivir and/or convalescent plasma in traditional and online U.S. ...
Wang investigates dynamic electron spins in correlated magnets
2024-08-29
This summer, Yishu Wang was awarded a $719,000 research grant from the United States Department of Energy (DOE) to study the dynamic and microscopic behaviors of magnets with quantum mechanical properties.
Magnetism originates from electrons in a material. When the electrons in a material all spin in the same direction, as they do in metals like iron, the material is magnetic, with poles that attract or repel other magnetic materials.
“Magnets that we are using today can be viewed as static orderings of electrons, analogous to the static pattern of brushstrokes in a painting,” said Wang, a joint assistant professor in the Department of Materials Science and Engineering ...
Silicon chip propels 6G communications forward
2024-08-29
Terahertz communications represent the next frontier in wireless technology, promising data transmission rates far exceeding current systems.
By operating at terahertz frequencies, these systems can support unprecedented bandwidth, enabling ultra-fast wireless communication and data transfer. However, one of the significant challenges in terahertz communications is effectively managing and utilising the available spectrum.
The team has developed the first integrated terahertz polarisation (de)multiplexer implemented on a substrateless silicon base which they have successfully tested in the sub-terahertz J-band (220-330 GHz) for 6G communications and beyond.
The University of Adelaide’s ...
Community college students conduct research at UTA
2024-08-29
Studies have shown that undergraduate students who participate in research activities under the guidance of a faculty mentor are more likely to finish college. That’s one of the many reasons universities like The University of Texas at Arlington are increasing their investment into undergraduate research.
Such research opportunities are not offered at many two-year colleges. To help bridge this gap, Jianzhong Su, professor of mathematics at UTA, is piloting a new program where students from the North Lake campus of Dallas College can come to UT Arlington to participate in a paid research ...

Machine learning helps identify rheumatoid arthritis subtypes
2024-08-29
A machine-learning tool created by Weill Cornell Medicine and Hospital for Special Surgery (HSS) investigators can help distinguish subtypes of rheumatoid arthritis (RA), which may help scientists find ways to improve care for the complex condition.
The study published Aug. 29 in Nature Communications shows that artificial intelligence and machine learning technologies can effectively and efficiently subtype pathology samples from patients with RA.
“Our tool automates the analysis of pathology slides, which may one day lead to more precise and efficient disease diagnosis and personalized treatment for ...
Ancient gene gives spiders their narrow waist
2024-08-29
An ancient gene is crucial for the development of the distinctive waist that divides the spider body plan in two, according to a study publishing August 29th in the open-access journal PLOS Biology by Emily Setton from the University of Wisconsin-Madison, US, and colleagues.
The spider body is divided into two sections, separated by a narrow waist. Compared to insects and crustaceans, relatively little is known about embryonic development in spiders, and the genes involved in the formation of the spider waist are poorly understood.
To investigate, researchers sequenced genes expressed in embryos of the Texas brown tarantula (Aphonopelma hentzi) ...
