this study was conducted to enhance the antimicrobial properties and water absorption of sanitary papers. for this purpose, montmorillonite nano clay with bentonite brand (has a layered structure in which its thickness is nano metric), was processed with homogenizer to achieve a stable colloidal system with nanometer dimensions of particle size. then, different weight levels of raw and homogeni...

The synthesis and biological properties of some 3-vinylthio- and 3-vinylthiomethylcephem derivatives are described. Both series possess potent antibacterial activity. Among them, 3-[(Z)-2-cyanovinylthiomethyl]cephem derivative was found to have an expanded antibacterial spectrum.

The pharmacokinetics of the quinolone enoxacin were studied after a 600-mg oral dose was given to each of six male volunteers. The levels of the compound were measured in serum, blister fluid, and urine. Absorption was variable, with peak levels (mean, 3.7 micrograms/ml) being attained between 0.75 and 3.0 h (mean, 1.9 h). The serum elimination half-life was 6.2 h, and 71.6% of the drug was rec...

PURPOSE Sealants form a physical barrier between the oral environment and deep fissures that contribute to caries prevention. It is postulated that sealants possessing antibacterial properties are advantageous. The purpose of this study was to evaluate the antibacterial properties of four pit and fissure sealants using direct contact test (DCT) and agar diffusion test (ADT). METHODS For the D...

After it had been shown that the phenyl ether of ethylene glycol possessed antibacterial properties against Pseudomonas aerunosa (Berry, 1944) the antimicrobial and pharmacological activities of a number of related compounds were evaluated. Two of the compounds investigated in this connection have found clinical usefulness. These are mephenesin,3-o-toloxy-1, 2propanediol, widely used as a muscl...

This study examined the influence of variables in a finishing process for making cotton fabric with regenerable antibacterial properties against Staphylococcus aureus (S. aureus). 5,5-dimethylhydantoin (DMH) was coated onto cotton fabric by a pad-dry-plasma-cure method. Sodium hypochlorite was used for chlorinating the DMH coated fabric in order to introduce antibacterial properties. An orthogo...

Nanoparticle metal oxides represent new classes of important materials that are increasingly being developed for use in research and health-related applications. Highly ionic metal oxides are interesting not only for their wide variety of physical and chemical properties but also for their antibacterial activity. Although the in vitro antibacterial activity and efficacy of regular zinc oxides h...

Contact-active antibacterial surfaces play a vital role in preventing bacterial contamination of artificial surfaces. In the past, numerous researches have been focused on antibacterial surfaces comprising of antifouling upper-layer and antibacterial sub-layer. In this work, we demonstrate a reversed surface structure which integrate antibacterial upper-layer and antifouling sub-layer. These su...

background: in developing new products for skin care and wound treatment, biocompatibility plays a major role in the choice of ingredients. thymol, an essential oil extracted from thyme plant, exhibits outstanding antibacterial properties, but more importantly, it proves to be much more compatible to skin cells in comparison to some conventionally used antibiotic drugs and chemicals. objective:...
