The effect of an electric field on the antibacterial activity of columnar aligned silver nanorods was investigated. Silver nanorods with a polygonal cross section, a width of 20-60 nm and a length of 260-550 nm, were grown on a titanium interlayer by applying an electric field perpendicular to the
There is still considerable interest in cephem antibacterial agents. In fact, there are a significant number of patents submitted for this antibacterial class. All the new cephem derivatives, independent of which group they belong to (III to V), possess a 2-amino-5-thiazolyl or a
Even though a great number of antibiotics and antiseptic agents are available at present, these substances are often rendered ineffective by the capacity of bacteria to develop resistance to them. The importance of continuing research in this area cannot be sufficiently stressed. Of the various
Microalgae and plankton can be a rich source of bioactivity. However, induction of secondary metabolite production in lab conditions can be difficult. One simple way of bypassing this issue is to collect biomass in the field and screen for bioactivity. Therefore, bulk net samples from three areas
Alkaline agents are well-known for their disinfection capacities against pathogens even at the presence of organic materials, but the durability of their bactericidal efficacies under field conditions is unknown. Therefore, within the present study, two alkaline agents, namely bioceramic (BCX)
Inactivation of stationary phase Escherichia coli, Salmonella Typhimurium and Listeria innocua (10(8) CFU/ml) by high intensity pulsed electric fields (PEF) was studied in water and different buffers at pH 7.0. The fraction of survivors after PEF treatment with 300 pulses (5 Hz) of 26.7 kV/cm and a
This paper traces the growth of the field from the incidental finding of the hypoglycemic "side effect" of certain antibacterial sulfonamides and sulfonylureas (1942), to the establishment of islet beta cell stimulation and insulin release as a major mechanism of action of these drugs (1946), to the
The present study investigates the antibacterial activity of a photoactive float fabricated with visible light active N-F-TiO2 for the disinfection of field water widely contaminated with Gram positive and Gram negative bacteria like, Salmonella typhimurium (Gram negative), Escherichia coli (Gram
