Research can contribute to earlier diagnosis of diabetic neuropathy
Research conducted at Cruzeiro do Sul University in São Paulo, Brazil, can contribute to earlier diagnosis of diabetic neuropathy, a disorder characterized by damage to peripheral nerves, with symptoms such as pain and paresthesia (pricking, burning and numbness), mainly in the legs and feet.
In the study, a group led by Professor Paulo Barbosa de Freitas Júnior measured grip force in diabetic patients while they were holding and handling objects. The results were compared with data for healthy subjects and patients with other neurological diseases, such as multiple sclerosis, Parkinson s, and carpal tunnel syndrome (pain, numbness and tingling in the hand and arm caused by a pinched nerve in the wrist).

Quantum dots are manmade nanoparticles of semiconducting material comprising only a few thousand atoms. Because of the small number of atoms, a quantum dot s properties lie between those of single atoms or molecules and bulk material with a huge number of atoms. By changing the nanoparticles size and shape, it is possible to fine-tune their electronic and optical properties - how electrons bond and move through the material, and how light is absorbed and emitted by it.

A paper by a multidisciplinary team of scientists affiliated with various Brazilian institutions, including the University of São Paulo (USP) and the National Cancer Institute (INCA), shows that people of African descent are less likely to find a donor in the National Register of Voluntary Bone Marrow Donors (REDOME) than people with predominantly European ancestry.

REDOME is the world’s third-largest bone marrow bank, with more than 5 million registered voluntary donors.
