Neuropeptide Lacking in Diabetics Promotes Wound Healing

Posted by in categories: biotech/medical, life extension, neuroscience

“In adults with diabetes alone—where poor blood flow can lead to quickly worsening wounds that are often very slow or impossible to heal—the lifetime risk of developing a diabetic foot ulcer (DFU), the most common diabetes-related wound, is 20–35 percent and this number is rising with increased longevity and medical complexity of people with diabetes,” stated lead author, Yen-Zhen Lu, PhD, an investigator at ARMI.

Nociceptors— neurons that sense pain, tissue damage, and inflammation, among other functions— respond to wounds by producing a neuropeptide called calcitonin gene-related peptide (CGRP). “Nociceptor endings grow into injured skin and muscle tissues and signal to immune cells through the neuropeptide CGRP during the healing process,” the authors wrote. Immune cell response in neutrophils, monocytes, and macrophages are modified to encourage active repair in the region.

Individuals with diseases like diabetes or elderly people have reduced production of CGRP, leading to poor, inefficient, or incomplete wound healing. The new study explores the impact of CGRP alone by introducing it into diabetic mice as well as mice without nociceptors. “Delivery of an engineered version of CGRP accelerated wound healing and promoted muscle regeneration,” the authors wrote. “Remarkably, this neuropeptide acts on immune cells to control them, facilitating tissue healing after injury,” added co-author Mikaël Martino, PhD, associate professor, ARMI.

Spare Parts 3D launches new AI-powered 2D-to-3D model digitization tool

Posted by in categories: economics, robotics/AI

French software start-up Spare Parts 3D (SP3D) has launched the beta program of Théia, its new digital tool that can automatically create 3D models from 2D technical drawings.

As global geopolitical and economic factors pose challenges to supply chains, more companies are looking to digitize their inventories, allowing spare parts to be 3D printed locally and on demand. This digitization process, however, can be time-consuming and costly.

Integrating into the company’s AI-driven DigiPart software, SP3D’s new offering leverages deep learning technology to convert existing 2D drawings of spare parts into 3D printable models, reducing conversion times from days to minutes.

Can Transhumanism Rescue The West From The Threat Of AI?

Posted by in categories: biotech/medical, genetics, geopolitics, robotics/AI, transhumanism

Here’s a new Forbes review by world leading futurist Tracey Follows on the book: Transhuman Citizen:


What does Transhumanism, Ayn Rand and the U.S. Presidential election have in common? They are the connecting themes in a new book by Ben Murnane entitled, “Transhuman Citizen”

The book tells the story of Zoltan Istvan, a one-time U.S. Presidential candidate, who drove a coffin-shaped bus around the U.S. attempting to persuade the public that death is not inevitable and that transhumanism is a political as much as a scientific solution to the troubles of the 21st Century.

Neurological Shadows: The Cognitive Costs of Sleep Apnea Unraveled

Posted by in categories: biotech/medical, neuroscience

A new study indicates a link between sleep apnea and increased memory or thinking problems, based on self-reported data from over 4,000 participants.

People who experience sleep apnea may be more likely to also have memory or thinking problems, according to a preliminary study that will be presented at the American Academy of Neurology’s 76th Annual Meeting taking place April 13–18, 2024, in person in Denver and online. The study shows a positive association but did not determine whether sleep apnea causes cognitive decline.

Sleep apnea is when people stop and restart breathing repeatedly during sleep which can lower oxygen levels in the blood. Symptoms include snorting, gasping, and breathing pauses. People with the disorder may also experience morning headaches or have trouble focusing on tasks.
