It is now possible to develop an accessible passenger cabin for people with physical and sensory disabilities

Photograph of the interior of an airplane, showing the blue seats arranged along the cabin.

The difficulties faced by passengers with reduced mobility or sensory losses cause people with disabilities to forgo air travel. By mapping these users’ needs and based on technologies already available in the aviation industry, Brazilian researchers demonstrate that airlines can develop an accessible cabin. Read More →

HPV infection may not be responsible for prostate cancer, but it’s better to prevent

Photo of a man lying on a hospital equipment. Two health professionals are beside him. A metal plate is over the man's body.

Since effective vaccines against HPV already exist, understanding the dynamics between papillomavirus and prostate cancer is relevant because it can contribute to the development of strategies for prevention and early diagnosis, although prospective analysis does not clearly demonstrate a relationship.

Improvements in colonoscopy performance help prevent and treat colorectal cancer

Composition: photo of a person lying down being seen by three health professionals. Blue frame in the upper left corner with the text "Quality indicators in colonoscopy: Observational study in a supplementary health system" and link.

Colonoscopy plays an essential role in detecting and diagnosing lesions and tumors of the colorectal mucosa. The quality of the equipment used, the colonoscopist’s technical knowledge and practical skills interfere directly with the effectiveness of the procedure and an analysis of these indicators may reveal opportunities for positive interventions and the improvement of results.

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.

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.

Hybridization with transcription factor AREB increases drought resistance in elite soybean cultivars

Rectangular horizontal photo. Plantation a bit blurred. Thin, tall branches, leaves that look like pods hanging from the branches. The plants look dry, but this may be due to lighting. In the background, strong and diffuse sun. The whole image is very yellowish and with strong shadows.

Soybean cultivation requires attention due to its susceptibility to drought. The introgression of the AtAREB1 transgene into the LS93-0375 and BMX Desafio RR elite cultivars conferred a better physiological performance to the genotypes, proving to be an effective mechanism of genetic engineering for the reduction of the effects of water deficit.

Cameras and monitors improves experimental surgeries for correcting incisional hernia in rats

Horizontal rectangular photo. An oval cut in the skin of a mouse. It is possible to see inside the opening a mesh reminiscent of metal, the skin cut around the cut is red and almost translucent, the pinkish skin of the mouse with small spots and some white hairs around the part shaved for the cut. Surrounding the image is an opaque blue background.

The use of cameras and screens in surgical procedures with Wistar rats has demonstrated efficacy and high performance. The 50x magnified visualization with a low-cost system circumvents one of the main difficulties of experimental studies, enabling further research with biocompatible models that generate more accurate results.

Brusone: Wheat blast disease requires chemical control management and increased genetic resistance of crops

Composition. 8 images arranged horizontally 4x4. The top ones are close-up shots of long dark green leaves with straight light green lines and black or yellowish spots. The bottom ones are lime green wheat clumps, some have spots. The clumps are half oval half triangular and grow upwards from the stem. They also have small, long, thin leaves.

A fungal disease that attacks wheat cultivation threatens world food security by compromising up to 100% of infected crops. Research points to the importance of making crops less susceptible by combining chemical control and genetic resistance protocols to increase productivity and reduce losses. Read More →

More benefits, fewer risks: Tranexamic acid reduces bleeding and prevents complications in laparoscopic bariatric surgery

Flowchart of the patient analysis in English. At recruitment, starting from the total number of patients (62), 1 was excluded, 0 did not meet the criteria, 0 refused to participate. Allocation: starting from "Control - non-randomized (61)" comes out two arrows forming two horizontal columns. First column: allocated to control group (31), received tranexamic acid (0), follow-up (31), analysis (31). Second column allocated to the group that received tranexamic acid (30), received tranexamic acid (30), follow-up (30), analysis (30).

Medicine’s accessibility, easy administration protocol and absence of thrombogenic adversities indicate that tranexamic acid is a safe and low-cost strategy, applicable to all phases of laparoscopic sleeve gastrectomy surgery, optimizing recovery and reducing hospital stay of patients. Read More →
