Cellular regeneration process with porcine skin does not present risks of immunological rejection

Photo: Piece of pork skin, irregular shape similar to a rectangle, sort of yellowish.

Results of the analyzed protocol indicate the viability of the biomaterial for application in regenerative medicine, reducing incompatibility problems in graft and transplant recipients. Aspect and quality of the material obtained provided positive results in cell culture and proliferation, but the decellularization process still needs optimization to minimize hydrogel cytotoxicity.

Epidemiology and risk factors of hypoglycemia in type 1 diabetes in Brazil

Photo or composition. A cell phone and a blood glucose meter kit (two cylindrical objects, a round jar and the monitor with two buttons). Solid orange background.

Factors associated with hypoglycemia and severe hypoglycemia (SH) in individuals with type 1 diabetes mellitus (T1D) in Brazil shows that avoiding high doses of basal insulin and educating individuals about alcohol consumption and its consequence on glycemic control are simple measures that can contribute to reducing SH events.

Dissolution of agrominerals by bioweathering provides nutrients for corn growth

Four microscopic images of biotite, a mineral. In all four images, something that looks like a plate of broken glass at different angles.

Pure and ground samples of biotite schist and biotite syenite proved to be sources of macro- and micronutrients for corn plants. The discovery is relevant for the future guidance of fertilization protocols, correction and soil balance to maximize production through the use of silicate agrominerals as soil remineralizers.

Optical instrument helps monitor survival rate of patients undergoing liver transplant

Close-up photo of a surgery. One hand holds a cylindrical instrument similar to a thick needle, it has a thread at the top end. Another hand holds a pair of scissors. Both instruments are aimed at an opening in a person's body.

Fluorescence spectroscopy under violet light is a minimally invasive optical technique in liver transplant procedures. It demonstrated effectiveness as a complementary tool for monitoring liver grafts in cold perfusion, providing objective information to support the surgeons’ final decision regarding the use of organs for transplantation.

Although informal conjugal unions have become more common in Brazil, university educated women still seem to prefer formal marriages. More surprisingly, the gap between lower and higher educated women has increased, as the chances of lower educated women being in informal unions has grown faster than for higher educated.

Results from a fuzzy model show that intervention measures impede the spread of COVID-19 even with the vaccine

The fuzzy approach shows that intervention measures impede the spread of COVID-19. Even with the vaccine, the infection rate could be worse if safety measures are weakened. Results assist government decision making to minimize the spread of the pandemic by combining physical distancing measures with vaccines to contain the resurgences of the disease. Read More →
