MONDAY, March 18, 2024 (HealthDay News) — In people with type 1 diabetes, fluctuations in blood sugar levels can affect thinking skills in various ways, new research shows.
Researchers looked specifically at what’s known as cognitive processing speed (how fast people process incoming information) and attention.
“Our results demonstrate that people can differ a lot from one another in how their brains are impacted by glucose,” said study co-senior author Laura Germine.
Allergy shots can potentially lead to lasting remission of allergy symptoms, and it may play a preventive role in the development of asthma and new allergies.
Immunotherapy treatment (allergy shots) is based on a century-old concept that the immune system can be desensitized to specific allergens that trigger allergy symptoms. These symptoms may be caused by allergic respiratory conditions such as allergic rhinitis (hay fever) and asthma.
While common allergy medications often control symptoms; if you stop taking the medication(s), your allergy symptoms return shortly afterward. Allergy shots can potentially lead to lasting remission of allergy symptoms, and it may play a preventive role in terms of development of asthma and new allergies.
The Process Treatment involves injecting the allergen(s), causing the allergy symptoms. These allergens are identified by a combination of a medical evaluation performed by a trained allergist / immunologist and allergy skin or allergy blood tests.
Extinction is a regular part of nature. An estimated 99% of all species that have existed on Earth have gone the way of the dodo, sometimes because a fitter competitor came along or their environment changed (often because of humans) and they couldn’t adapt.
While life can go on relatively unchanged after the extinction of some species, the loss of a keystone species — one that plays a significant role in its environment — can upend an ecosystem.
Now, researchers exploring the idea of “de-extinction” believe that science might be able to intervene and restore the balance.
Small, shelled, and unassuming, chitons have eyes unlike any other creature in the animal kingdom.
Some of these marine mollusks have thousands of bulbous little peepers embedded in their segmented shells, all with lenses made of a mineral called aragonite. Although tiny and primitive, these sensory organs called ocelli are thought to be capable of true vision, distinguishing shapes as well as light.
Other chiton species, however, sport smaller ‘eyespots’ that function more like individual pixels, much like the components of an insect’s or mantis shrimp’s compound eye, forming a visual sensor distributed over the chiton’s shell.
Foundation models, advanced artificial intelligence systems trained on large-scale datasets, hold the potential to provide unprecedented advancements for the medical field. In computational pathology (CPath), these models may excel in diagnostic accuracy, prognostic insights, and predicting therapeutic responses.
Monitoring levels of DNA shed by tumors and circulating in the bloodstream could help doctors accurately assess how gastroesophageal cancers are responding to treatment, and potentially predict future prognosis, suggests a new study led by researchers at the Johns Hopkins Kimmel Cancer Center and its Bloomberg–Kimmel Institute for Cancer Immunotherapy.
At first glance, Rabih O. Al-Kaysi’s molecular motors look like the microscopic worms you’d see in a drop of pond water. But these wriggling ribbons are not alive; they’re devices made from crystallized molecules that perform coordinated movements when exposed to light. With continued development, Al-Kaysi and colleagues say, their tiny machines could be used by physicians as drug-delivery robots or engineered into arrays that direct the flow of water around submarines.
Exploring the cutting edge of genetic engineering, the development of programmable recombinases and zinc finger domains is ushering in a new era of precision in DNA manipulation. These advances enable precise genomic alterations, from single nucleotide changes to the insertion of large DNA segments, potentially transforming the landscape of therapeutic gene editing and opening new possibilities in personalised medicine.
