The worldwide prevalence reaches up to 80% people aged 15 17 who have symptoms acne, and condition often persists into adulthood. In pathogenesis in addition pathological hyperkeratosis inflammation, an important role played by such factors as massive microbial contamination, species composition, biological properties pat...

Soldiers of some eusocial insects exhibit an altruistic self-destructive defense behavior in emergency situations when attacked by large enemies. The swarm-forming invasive millipede, Chamberlinius hualienensis, which is not classified as eusocial animal, exudes irritant chemicals such as benzoyl cyanide as a defensive secretion. Although it has been thought that this defensive chemical was con...

A set of new water-soluble organic peroxides has been synthesized and evaluated for in vitro antibacterial activity as part of an effort to develop new antibacterial agents for the treatment of acne vulgaris. The water solubility of these new dialkyl peroxides and peroxyesters was achieved by incorporating either a quaternary ammonium group or a polyethylene glycol moiety. These peroxides are e...

The goal of this research is to prepare novel amphiphilic graft copolymers (nonionic) based on hydrophilic poly (ethylene glycol) methyl ether (mPEG) and hydrophobic methacrylate (MMA) at room temperature pressure. To generate P(mPEG-g-MMA) grafts, was synthesized grafted with varied ratios in the existence benzoyl peroxide as an initiator utilizing a macro-free radical procedure under effect h...
