Researchers in Brazil have documented the immune system’s response in a living patient who received a genetically modified pig kidney transplant. This marks the first instance of such a procedure being performed on a living human subject, providing detailed insights into how the body reacts to xenotransplantation. The findings aim to contribute to the development of therapies designed to prevent organ rejection in similar cases. The study closely monitored the patient’s immune response [...]

Researchers have developed an artificial saliva mouthwash containing a laboratory-modified protein derived from sugarcane, known as CANECPI-5, to assist in protecting teeth for patients undergoing head and neck cancer treatment. Radiotherapy in these cases often damages salivary glands, leading to reduced saliva production. Saliva plays a critical role in maintaining oral health by controlling bacteria and preventing disease. The artificial saliva aims to address the challenges faced by [...]

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have identified a previously unknown mechanism used by SARS-CoV-2, the virus responsible for COVID-19, to evade the human immune system. The study reveals that, beyond its ability to bypass immune defenses prior to entering host cells—a trait shared with many other viruses—SARS-CoV-2 employs an additional strategy by altering the host cell’s RNA. This manipulation disrupts normal cellular functions and suppresses the [...]

A recent study conducted by researchers at the Federal University of São Carlos (UFSCar) in Brazil, in collaboration with University College London (UCL) in the United Kingdom, has found that individuals over the age of 50 who experience both abdominal obesity and muscle loss face an 83% higher risk of death compared to those without these conditions. The research highlights the significant health risks associated with the combination of excess abdominal fat and reduced muscle mass in older [...]

Researchers in Brazil have verified the anti-inflammatory, analgesic, and anti-arthritic properties of the Joseph’s Coat plant (Alternanthera littoralis), a species traditionally used in folk medicine. The study, conducted by teams from the Federal University of Grande Dourados (UFGD), the State University of Campinas (UNICAMP), and São Paulo State University (UNESP), also confirmed the safety of the plant for medicinal use. The research highlights the potential therapeutic benefits of [...]

Researchers at the State University of Campinas (UNICAMP) in São Paulo, Brazil, have developed a sustainable method for extracting isoflavones from soybean meal. The study demonstrated that this process enhances the bioavailability of isoflavones, which are compounds known for their potential health benefits. The findings highlight the efficiency of this innovative approach in utilizing soybean meal, a byproduct of soybean oil and protein production. The research focused on creating an [...]

Brazil, the third-largest producer and consumer of beer globally, currently relies on imports for nearly all its hop supply. Less than 1% of the hops used in Brazilian beer production are grown domestically. A new initiative in the Vale do Ribeira region of São Paulo aims to address this dependency by enhancing local hop cultivation through advanced technology and fostering the creation of innovative bioproducts. The project brings together Brazilian scientists and agricultural producers to [...]

Brazilian researchers have developed a portable and low-cost biosensor capable of detecting altered levels of a specific protein linked to psychiatric disorders, including depression, schizophrenia, and bipolar disorder. The device identifies the protein in saliva samples, offering a rapid and accessible method for monitoring changes associated with these mental health conditions. The biosensor’s design aims to facilitate early detection of psychiatric disorders, which is critical for [...]

An early trial of the world’s first vaccine targeting elephant endotheliotropic herpesvirus (EEHV) has demonstrated safety and effectiveness, according to findings from an international research team. The study, conducted by researchers at the University of Surrey in collaboration with Chester Zoo and the Animal and Plant Health Agency, revealed that the vaccine triggers a robust immune response against the virus. EEHV is a leading cause of death among young Asian elephants, making this [...]
