objective(s): several beneficial effects have been attributed to the probiotic lactic acid bacteria. it was determined that lactobacilli can exert antiproliferative effects on the various cancer cell lines including colon cancer. effects of lactic acid bacteria on colon cancer may vary from strain to strain and there is a need to find the new probiotic strains with tumor suppressing properties ...

In the present work, we have investigated the concentration dependences of electrical conductivity of monopolymer composites with graphite nanoplatelets or multiwall carbon nanotubes and hybrid composites with both multiwall carbon nanotubes and graphite nanoplatelets. The latter filler was added to given systems in content of 0.24 vol%. The content of multiwall carbon nanotubes is varied from ...

Electroconductive hydrogels with stimuli-free self-healing and self-recovery (SELF) properties high mechanical strength for wearable strain sensors is an area of intensive research activity at the moment. Most electroconductive hydrogels, however, consist static bonds dynamic SELF performance, presenting a challenge to improve both into one single hydrogel. An alternative strategy successfully ...

In this study, we designed a microbial electrochemical fluidized bed reactor (ME-FBR), with an electroconductive anodic bed made of activated carbon particles for treating a brewery wastewater. Under a batch operating mode, acetate and propionate consumption rates were 13-fold and 2.4-fold higher, respectively, when the fluidized anode was polarized (0.2 V) with respect to open circuit conditio...

Electrically conductive and biologically active scaffolds are desirable for enhancing adhesion, proliferation and differentiation of a number of cell types such as neurons. Hence, the incorporation of neuroactive molecules into electroconductive polymers via a specific and stable method is essential for neuronal tissue engineering applications. Traditional conjugation approaches dramatically im...

The Ar ion irradiation method has a high potential for the batch fabrication of single carbon nanofibers (CNFs) onto the tip of cantilevers, and is known to have excellent mechanical characteristics. In this study, we analyzed the electrical properties of ion-induced CNFs. For this purpose, current–voltage (I–V) properties were measured using an atomic force microscope (AFM). Commercial-type Si...

The effects of bafilomycin A(1), a blocker of V-type H(+)-ATPases, were investigated in Malpighian tubules of Aedes aegypti. Bafilomycin A(1) reduced rates of transepithelial fluid secretion and the virtual short-circuit current (vI(sc)) with an IC(50) of approximately 5 micromol l(-)(1). As vI(sc) decreased, the electrical resistance increased across the whole epithelium and across the apical ...
