Fresh fish degradation and advances in preservation using physical emerging tec...
Tavares, Jéssica; Martins, Ana; Lima, Vasco; Amaral, Renata A; Pinto, Carlos A; Silva, Ana M; Saraiva, Jorge A; Fidalgo, LilianaFresh fish is a highly perishable food characterized by a short shelf-life, and for this reason, it must be properly handled and stored to slow down its deterioration and to ensure microbial safety and marketable shelf-life. Modern consumers seek fresh-like, minimally processed foods due to the raising concerns regarding the use of preservatives in foods, as is the case of fresh fish. Given this, emergent prese...
Robust gap repair in the contractile ring ensures timely completion of cytokinesis
Silva, Ana M; Osório, Daniel S; Pereira, Antonio J; Maiato, Helder; Pinto, Inês Mendes; Rubinstein, Boris; Gassmann, Reto; Telley, Ivo AndreasCytokinesis in animal cells requires the constriction of an actomyosin contractile ring, whose architecture and mechanism remain poorly understood. We use laser microsurgery to explore the biophysical properties of constricting rings in Caenorhabditis elegans embryos. Laser cutting causes rings to snap open. However, instead of disintegrating, ring topology recovers and constriction proceeds. In response to sev...
