Collagen and gelatin are essential biomaterials widely used in industries such as food, cosmetics, healthcare, and pharmaceuticals. Traditionally derived from animal tissues, these proteins are facing growing demand for more sustainable and ethical production methods. Precision fermentation (PF) offers a promising alternative by using genetically e...

The global pandemic due to the SARS-CoV-2 Coronavirus has caused significant impact on various sectors of society, e.g., health, science, and economy, with a remarkable change in environmental aspects. The present study focused on an analysis of the spread of COVID-19 in South America, highlighting the impacts of lockdown policies on the air qualit...

Neglected tropical diseases are those caused by infectious agents or parasites and are considered endemic in low-income populations. These diseases also have unacceptable indicators and low investment in research, drug production, and control. Tropical diseases such as leishmaniasis are some of the main causes of morbidity and mortality around the...

We describe an outbreak of leishmaniasis in seven guinea pigs (Cavia porcellus) in which nodular ulcerated skin lesions of varying sizes were observed in the nasal cavity, upper lip, pinnae, vulva, and periarticular region of the limbs. Cytologic exam of collected samples of the lesions in the auricle of one of the animals revealed macrophages cont...

Electrochemical immunosensors are excellent alternatives to prepare portable platforms used for rapid and inexpensive diagnostic of infectious diseases such as the recently emerged COVID-19. Incorporating synthetic peptides as selective recognition layers combined with nanomaterials such as gold nanoparticles (AuNPs) can significantly enhance the a...

Background: The recent geographic expansion of Leishmania infantum vectors in the triple border area of Argentina, Brazil, and Paraguay has highlighted the need to know the seasonality, parasite infection rate, and the factors that contribute the dispersal and handling of this parasite. Methods: Entomological, quantitative longitudinal studies were...

The development of immunosensors to detect antibodies or antigens has stood out in the face of traditional methods for diagnosing emerging diseases such as the one caused by the SARS-CoV-2 virus. The present study reports the construction of a simplified electrochemical immunosensor using a graphene-binding peptide applied as a recognition site to...

Sugarcane is one of the most promising biomass resources in the developing bioeconomy. It is a source of fermentable sugars and of lignocellulosic biomass that can be converted to a variety of products. Brazil is the leading producer of sugarcane, with 734 million tons projected for 2022 and a yield of 74 tons per hectare. Sugarcane is already an i...

Lipids from microbial sources are valuable substitutes of animal and vegetable oils, with potential applications such as food ingredients and supplements, biofuels, biolubricants, biosurfactants, and wax esters. They gained prominence as partial substitutes of fish-oil in specialty food products. Eicosapentaenoic acid, docosahexaenoic acid (omega-3...
