Gut bacteria engineered to act as tumor GPS for immunotherapies

Immunotherapeutic approaches have substantially improved the treatment of patients with advanced malignancies. However, most advanced and metastatic malignancies remain incurable and therefore represent a major unmet need.

Neuroscience

DNA molecules with 'invisibility cloak' sequences can selectively target diseased cells in motor neuron disease

Researchers at the Francis Crick Institute and the UCL Queen Square Institute of Neurology have developed DNA molecules which contain "invisibility cloak" sequences, preventing healthy cells from reading the messages they ...

Stem cell transplants repair macular holes in primate study

Human stem cell transplants successfully repaired macular holes in a monkey model, researchers report October 3 in the journal Stem Cell Reports. After transplantation, the macular holes were closed by continuous filling ...

Diabetes

A new injectable shows promise to prevent and treat hypoglycemia

People with diabetes take insulin to lower high blood sugar. However, if glucose levels plunge too low—from taking too much insulin or not eating enough sugar—people can experience hypoglycemia, which can lead to dizziness, ...

Neuroscience

Study hints at ways to generate new neurons in old brains

Most neurons in the human brain last a lifetime, and for good reason. Intricate, long-term information is preserved in the complex structural relationships between their synapses. To lose the neurons would be to lose that ...

Exploring how melanin influences clinical oxygen measurements

Obtaining accurate clinical measurements is essential for diagnosing and treating a wide range of health conditions. Regrettably, the impact of skin type and pigmentation is not equally considered in the design and calibration ...

Neuroscience

Study urges caution when comparing neural networks to the brain

Neural networks, a type of computing system loosely modeled on the organization of the human brain, form the basis of many artificial intelligence systems for applications such as speech recognition, computer vision, and ...

Innovative coating on medical devices fights bacterial infections

Georgios Sotiriou, principal researcher at the Department of Microbiology, Tumor and Cell Biology, and his colleagues have developed a durable coating for medical devices which is activated by light, providing on-demand disinfection.

PCR platform for fighting pandemics is fast, open and digitalized

PCR processes are the diagnostic gold standard when it comes to identifying coronavirus infections. Unlike rapid antigen tests, they function even in the case of a low viral load and detect the pathogen with a high level ...

A cost-effective alternative to a PCR test

Speed or accuracy? As far as COVID-19 tests go, this was the choice you had to make. In the future, this dilemma could be a thing of the past. The Pathogen Analyzer combines the advantages of PCR testing and rapid antigen ...

Cardiology

New troponin test improves heart attack diagnostics

A new test has been developed in Turku, Finland, that helps in separating heart attack patients from those whose cardiac troponin values are elevated due to renal insufficiency.

Oncology & Cancer

Transistors help identify cancer cell markers

Having biopsies taken and endless tests run is nobody's idea of a good time, even if it's necessary for monitoring your health. Now, researchers from Japan report the development of a new technique that could make testing ...

Radiology & Imaging

Artificial intelligence methods may replace histochemical staining

Pathologists observe tissue samples by staining them first. However, the standard procedures for staining tissue samples in histopathology are time-consuming and require specialized laboratory infrastructure, chemical reagents, ...

Ophthalmology

A new device for early diagnosis of degenerative eye disorders

Researchers at an EPFL lab have developed an ophthalmological device that can be used to diagnose some degenerative eye disorders long before the onset of the first symptoms. In early clinical trials, the prototype was shown ...

Radiology & Imaging

AI model for screening of leadless implanted electronic devices

Small leadless implanted electronic devices (LLIEDs) have emerged as a safer alternative to lead-dependent cardiac rhythm-management devices, with advancements in miniaturization, battery technology, and communication. Intrathoracic ...

New tech aims to reduce racial disparities in blood measurements

A team led by a University of Texas at Arlington bioengineering professor and an Austin businessman has published key findings in the BMJ Innovations that illustrate how a new device measures hemoglobin more accurately in ...
