Regular and frequent blood glucose monitoring is vital in managing diabetes treatment plans and preventing severe complications. Because current invasive techniques impede patient compliance and are not infection-free, many noninvasive methods have been proposed. Among them, optical methods have drawn much attention for their rich optical contrast, but their resolution is degraded in deep tissue. Here, we present an ultrasound-modulated optical sensing (UOS) technique to noninvasively monitor glucose that uses an infrared laser (1645 nm) and a single-element focused ultrasound transducer. Focused ultrasound waves can acoustically localize diffused photons in scattering media, and thus optical contrast can be represented with much enhanced spatial resolution.
Non-invasive, early detection of invasive cancers — dr. patrizia paterlini-brechot, founder, rarecells diagnostics, ISET technology.
Dr. Patrizia Paterlini-Bréchot is a tenured Professor of Cell and Molecular Biology and Oncology at Paris Descartes University and head of a research team at the French National Institute of Health and Medical Research (INSERM).
Dr. Paterlini-Bréchot studied medicine at the University of Modena and Reggio Emilia, where she specialized in hematology and oncology. In 1988 she turned her focus on research in cell and molecular biology and published over 80 research articles and reviews in national and international scientific journals.
The work of Dr. Paterlini-Bréchot led to the discovery of the ISET test (Isolation by SizE of Tumor cells) permitting the isolation and characterization of circulating tumor cells (CTCs), a type of cell that has shed into the vasculature from a primary tumor, is carried around the body in the blood circulation, and can extravasate and become seeds for the subsequent growth of additional tumors (metastases) in distant organs, a mechanism that is responsible for the vast majority of cancer-related deaths.
The ISET test also has interesting applications for the isolation of fetal cells in a mother’s body for potential use in prenatal diagnoses.
The ISET discovery has led Dr. Paterlini-Bréchot to found her own company named Rarecells Diagnostics to further develop and commercialize the ISET technique.
Dr Paterlini-Bréchot has received numerous awards and honors including Best thesis in Medicine (1978), the Best research in Hematology (1979), Assistance Publique / Hôpitaux de Paris (19952002), Technological development (2007), and European Inventor Award Finalist (2019). She is listed as an inventor on numerous patents.
An antioxidant found in green tea may increase levels of p53, a natural anti-cancer protein, known as the “guardian of the genome” for its ability to repair DNA damage or destroy cancerous cells.
NASA, in collaboration with other leading space agencies, aims to send its first human missions to Mars in the early 2030s, while companies like SpaceX may do so even earlier. Astronauts on Mars will need oxygen, water, food, and other consumables. These will need to be sourced from Mars, because importing them from Earth would be impractical in the long term. In Frontiers in Microbiology, scientists show for the first time that Anabaena cyanobacteria can be grown with only local gases, water, and other nutrients and at low pressure. This makes it much easier to develop sustainable biological life support systems.
British scientists are developing ‘universal Covid jab’ that would effectively beat all variants of the virus in as little as a YEAR.
Nottingham University researchers are working with Oxford-based cancer vaccine firm Scancell (pictured, its chief medical officer) to create the universal vaccine.
Engineers at the University of California San Diego have developed a soft, stretchy skin patch that can be worn on the neck to continuously track blood pressure and heart rate while measuring the wearer’s levels of glucose as well as lactate, alcohol or caffeine. It is the first wearable device that monitors cardiovascular signals and multiple biochemical levels in the human body at the same time.
“” This type of wearable would be very helpful for people with underlying medical conditions to monitor their own health on a regular basis,” co-first author of the study Lu Yin said in a news release.
New wearable device converts body heat into electricity. “It would also serve as a great tool for remote patient monitoring, especially during the COVID-19 pandemic when people are minimizing in-person visits to the clinic,” Yin, a nano-engineering doctoral student at the University of California, San Diego.
In addition to monitoring chronic conditions like diabetes and high blood pressure, as well as pinpointing the onset of sepsis, the patch could help predict people at risk of becoming severely ill with COVID-19.
Scientists have developed a thin, flexible skin patch, worn on the neck, that can provide all-in-one health monitoring capabilities, including the wearer’s heart rate, blood pressure and glucose levels.
According to ‘The Daily Telegraph’, the invisible coating on facemasks attacks the virus by rapturing its outer layer, effectively eliminating all new mutant variants, including the UK’s so-called Kent variant and the South African variant.
