nowadays, hydrogels are widely used as wound dressings in biomedical applications. similar to other types of the moist (wet) wound dressings, it is necessary to have sufficient information about their dehydration kinetics during the pre-usage period (e.g. storage duration) and also the wound healing process. in this work, hydrogel wound dressings based on polyvinyl alcohol were prepared by cycl...

abstract cerebral sinovenous thrombosis (csvt) in children has rarely been reported in the literature, especially without underlying disorder. it has increasingly been diagnosed due to clinical awareness and sensitive neuroimaging techniques. the aim of this article was to report a case of cerebral sinovenous thrombosis without underlying disorder. we reported a 5 year old girl, presented with ...

the aim of this study was to investigate the effect of the addition of commercial lipase in various forms on the acceleration of the ripening of uf-feta cheese. commercial lipase from aspergillus niger was encapsulated by using silica composition based on sol-gel method. lipase was then added to cheeses in three forms, namely, free lipase, encapsulated lipase, and encapsulated lipase with arabi...

objective(s): drug delivery via mucosal routes has been confirmed to be effective in inducing strong immune responses. liposomes could enhance immune responses and mucoadhesive potentials, make them useful mucosal drug delivery systems. coating of liposomes by mucoadhesive polymers succeeded in enhancing immune responses. our studies aim at preparation and characterization of trimethylchitosan-...

Aqueous zinc-ion batteries (ZIBs) have attracted immense attention for flexible energy storage devices due to their high safety and low cost. However, conventional aqueous ZIBs will undergo severe capacity loss at subzero temperature the inevitably freeze of electrolytes. In addition, under large bending or stretching strains, encapsulation would be damaged, which causes evaporation water in el...

We give a direct construction of a certificateless key encapsulation mechanism (KEM) in the standard model that is more efficient than the generic constructions proposed before by Huang and Wong [9]. We use a direct construction from Kiltz and Galindo’s KEM scheme [10] to obtain a certificateless KEM in the standard model; our construction is roughly twice as efficient as the generic construction.
