Heart organoids simulate pregestational diabetes-induced congenital heart disease

Posted by in category: biotech/medical

An advanced human heart organoid system can be used to model embryonic heart development under pregestational diabetes-like conditions, researchers report in the journal Stem Cell Reports.

The organoids recapitulate hallmarks of pregestational diabetes-induced congenital heart disease found in mice and humans. The findings also showed that (ER) stress and lipid imbalance are critical factors contributing to these disorders, which could be ameliorated with exposure to omega-3s.

Is There a Place for Digital Pathology in Cancer Diagnosis?

Posted by in categories: biotech/medical, life extension

Histopathology describes the process of examining pieces of tissue using a microscope. Light microscopic (LM) examination of tissue helps diagnose several types of cancer by allowing pathologists to view cellular changes within a biopsy sample.

The workload of pathologists has increased in recent years due to policies that encourage screening for early cancer diagnoses. In addition, longer life expectancies and scientific advances have led to an increased number of cancer survivors, further increasing the need for pathology evaluations. Thus, strategies to efficiently utilize the limited pathology resources have become essential to maintaining standards of care and the health and safety of patients.

Digital pathology (DP) has emerged as an alternative method for analyzing tissue samples by stitching together digital images from histopathology slides. Automated slide scanners can rapidly generate these high-resolution images with minimal human interaction. In addition to the speed, DP does not require a microscope, offering remote viewing possibilities. Pathologists and other healthcare professionals can easily share images.

Daedalus, which is building precision-manufacturing factories powered by AI, raises $21M

Posted by in categories: biotech/medical, robotics/AI

A fledgling startup founded by one of OpenAI’s first engineering hires is looking to “redefine manufacturing,” with AI-powered factories for creating bespoke precision parts.

Daedalus, as the company is called, is based in the southwestern German city of Karlsruhe, where its solo factory is currently housed. Here, Daedalus takes orders from industries such as medical devices, aerospace, defense, and semiconductors, each requiring unique components for their products. For example, a pharmaceutical company might require a customized metal casing for a valve used in the production of a particular medicine.

As it looks to ramp up operations with a view toward opening additional factories in its domestic market, Daedalus today announced it has raised $21 million in a Series A round of funding led by Nokia-funded NGP Capital, with participation from existing investors Khosla Ventures and Addition.

Urokinase therapy improves diabetic foot ulcers healing and decreases CV events in diabetes patients

Posted by in category: biotech/medical

Urokinase therapy improves diabetic foot ulcer healing and decreases CV events in diabetes patients suggests a new study published in the BMJ Open Diabetes Research & Care.

Diabetic foot ulcer (DFU) is a disabling complication of diabetes mellitus. Here, we attempted to assess whether long-term intrafemoral artery infusion of low-dose urokinase therapy improved Diabetic foot ulcers and decreased cardiovascular events in patients with Diabetic foot ulcers were randomized to continuous intrafemoral thrombolysis or conventional therapy groups. The continuous intrafemoral thrombolysis group received continuous intrafemoral urokinase injection for 7 days, and conventional therapy just received wound debridement and dressing change. Then, a follow-up of average 6.5 years was performed. Results: Compared with conventional therapy, at the first 1 month of intervention stage, the ulcers achieved a significant improvement in continuous intrafemoral thrombolysis group including a complete closure (72.4% vs 17.5%), an improved ulcer (27.6% vs 25.8%), unchanged or impaired ulcer (0% vs 56.7%). During the 6.

Organic semiconductors with proton-hopping promise

Posted by in categories: biotech/medical, electronics

Chemists at RIKEN have developed a method for making synthetic derivatives of the natural dye indigo that doesn’t require harsh conditions. This discovery could inspire advances in electronic devices, including light-responsive gadgets and stretchy biomedical sensors.

Semiconductors based on organic molecules are attracting much interest because—unlike conventional rigid semiconductors based on silicon—they could be flexible, ductile and lightweight, opening up new possibilities for designing semiconductor devices.

Organic molecules also have the advantage of realizing a broad range of structures. “Organic semiconductors have flexibility in molecular design, enabling them to adopt new functionalities,” says Keisuke Tajima of the RIKEN Center for Emergent Matter Science, who led the research.

Combining materials may support unique superconductivity for quantum computing

Posted by in categories: biotech/medical, computing, quantum physics

A new fusion of materials, each with special electrical properties, has all the components required for a unique type of superconductivity that could provide the basis for more robust quantum computing. The new combination of materials, created by a team led by researchers at Penn State, could also provide a platform to explore physical behaviors similar to those of mysterious, theoretical particles known as chiral Majoranas, which could be another promising component for quantum computing.

The new study appears in the journal Science. The work describes how the researchers combined the two magnetic materials in what they called a critical step toward realizing the emergent interfacial , which they are currently working toward.

Superconductors—materials with no —are widely used in digital circuits, the powerful magnets in imaging (MRI) and , and other technology where maximizing the flow of electricity is crucial.
