When food is scarce, stress hormones direct the immune system to operate in "low power" mode to preserve immune function while conserving energy, according to researchers at Weill Cornell Medicine. This reconfiguration is crucial to combating infections amid food insecurity.

When food is scarce, stress hormones direct the immune system to operate in “low power” mode to preserve immune function while conserving energy, according to researchers at Weill Cornell Medicine. This reconfiguration is crucial to combating infections amid food insecurity. “Both famine and infectious disease have been with us throughout our evolutionary history and often occurred at the same time. Yet little is known about how nutrition affects the immune system,” said senior [...]

Researchers at São Paulo State University (UNESP) in Brazil have demonstrated in rats that a synthetic version of oxytocin can prevent anxiety-related behaviors caused by social stress. The study was published in the journal Progress in Neurobiology and reinforces the role of oxytocin and the neural circuits associated with it in modulating anxiety. It also paves the way for new therapeutic approaches. "We observed that, after a series of experiments generating social stress in male [...]

Raise your hand if you dreaded chemistry lessons at school. Apart from a few exceptional cases, this discipline is often perceived as difficult, abstract and removed from real life. This affects students' motivation and choices, discouraging them from pursuing academic and professional careers in this important and, in fact, fascinating field. In a new article published in JCOM, a team of Brazilian researchers — Ariane Carolina da Rocha, Ana Carolina Steola and Ana Cláudia [...]

Scientists from the University of São Paulo in Brazil are exploring new ingredients, including sunflower seed flour, that can improve the nutritional quality of bread without sacrificing taste or practicality. One promising option that has emerged is partially defatted sunflower seed flour – a material that is left behind after sunflower oil is produced. This byproduct has has shown the potential for enriching bread with protein, fibre and antioxidant compounds. According to Science [...]

Researchers in Brazil created a flexible and transparent biofilm from fish skin that could be used in food packaging, pharmaceuticals and biomedical products in the place of synthetic plastics. “We’ve been working for over 25 years on the development of films based on biopolymers, such as proteins and polysaccharides, with the aim of applying this material to food packaging and reducing the environmental impact, since there are many problems associated with the accumulation of synthetic [...]

Using the skin of an Amazonian fish known as tambatinga as the raw material, researchers in Brazil have developed a gelatin based biofilm that can serve as a more sustainable option for food packaging. The work was carried out by a team at the University of Sao Paulo (USP) and EMBRAPA Pecuaria Sudeste, a decentralized unit of the Brazilian Agricultural Research Corporation located in Sao Carlos in the state of Sao Paulo. Tambatinga is produced by crossing female tambaqui (Colossoma [...]

A study conducted in Brazil by researchers at the Federal University of São Paulo (UNIFESP) and the ABC Medical School (FMABC) warns that the prolonged use of proton pump inhibitors (PPIs) can impair nutrient absorption. PPIs are a class of drugs that includes medications such as omeprazole, pantoprazole, and esomeprazole. They are used to treat gastric disorders. Using them inappropriately for periods longer than recommended by physicians can cause nutritional deficiencies, such as anemia, [...]

Using the skin of an Amazonian fish known as tambatinga as the raw material, researchers at the University of São Paulo (USP) and EMBRAPA Pecuária Sudeste – a decentralized unit of the Brazilian Agricultural Research Corporation (EMBRAPA) located in São Carlos, São Paulo state – have developed a biofilm that can be used in food packaging. The tambatinga, the result of crossbreeding the female tambaqui (Colossoma macropomum) and the male pirapitinga (Piaractus brachypomus), is [...]
