34], adult acclimation [25,35,36] and developmental acclimation [25,34,37,38]. This fly is capable of surviving a three days exposure at − 7.5 °C after dynamic acclimation (i.e. gradual cooling) [39]. Despite the economic importance...
Micronutrient such as Fe play a vital role in various physiological functions of plants, including chlorophyll synthesis and DNA formation. However, Fe is often inaccessible to plants due to high soil pH and aerobic conditions. Ethylenediaminetetraacetic acid (Fe-EDTA) is a chelated form of Fe, ...

Global plastic production has increased exponentially since manufacturing commenced in the 1950’s, including polymer types infused with diverse additives and fillers. While the negative impacts of plastics are widely reported, particularly on marine ver
Table 1 Summary of strains with the ability to degrade rubber Full size table Degradation of the plastic family Plastic is a broad term that encompasses various polymers, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS). These materials have taken ...
Therefore, the development of biodegradable polyesters as well as the bioconversion of plastic waste represent two efficient strategies for a circular economy whereby waste prevention and recycling are encouraged. So far, a number of biodegradable polymers, such as poly(lactic acid) (PLA) [6, 7],...
Compared with fresh cells (a), cells lyophilized with 7% raffinose (b) maintained higher levels of cell activity after storage and were more suitable for direct use Full size image Lyophilization is a method used to solve these challenges. By storing the microorganism in a powdered form at a ...
Sternal wound infection (SWI) is the most common complication of the median sternal incision. The treatment time is long, and the reconstruction is difficult, which causes challenges for surgeons. Plastic surgeons were often involved too late in such clinical scenarios when previous empirical treatment...
