Novel targets identified for treatment of schistosomiasis
Publicado em 04 agosto 2023
The worms that cause schistosomiasis (Schistosoma mansoni) are unusual in several ways, especially the fact that male and female adults must stay paired together throughout their lives for reproduction to be successful. Females may produce as many as 3,000 eggs per day. Approximately half reach the host’s gut or bladder. The rest are swept away via the blood to the liver and spleen, where they cause severe inflammation and liver cirrhosis, the main cause of mortality.

Large mammals make soil more fertile in tropical forests
Publicado em 18 janeiro 2021The White-lipped peccary (Tayassu pecari) is a boar-like hoofed mammal found throughout Central and South America. These animals roam the forest in bands of 50 to 100 individuals, eating a wide variety of foods. In Brazil’s Atlantic Rainforest, they prefer the fruit of the jussara palm Euterpe edulis. The jussara is very abundant in this biome, probably thanks to vast amounts of dung, urine, and soil trampling by peccaries as well as tapirs (Tapirus terrestris) and other fruit-eating [...]ver notícia -
Scientists study use of abundant enzyme in tumor cells to monitor cancer treatment
Publicado em 13 janeiro 2021The abundant presence of an enzyme known as low molecular weight protein tyrosine phosphatase (LMWPTP) in tumor cells has long been considered an indicator of cancer aggressiveness and metastatic potential. It is also known to perform important functions in cells under normal conditions, participating both in the proliferation process and in the regulation of intracellular systems. Research continues on its role in the progression of cancer. In Brazil, a group of researchers from the Bioassay [...]ver notícia -
Tube-dwelling anemone toxins have pharmacological potential, mapping study shows
Publicado em 30 outubro 2020Researchers based in Brazil and the United States have completed the first-ever mapping exercise to profile the toxins produced by tube-dwelling anemones, or cerianthids, a family of marine animals belonging to the same phylum (Cnidaria) as sea anemones, jellyfish and corals. The analysis revealed that the toxins that can act on the nervous system, cardiovascular system, and cell walls, among other functions, paving the way to the discovery of novel medications. “Tube anemones and sea [...]ver notícia
