Rhus chinensis Mill is a potential plant for phytoremediation of Pb and able to uptake copious amount Pb. However, little known about the pathways properties in this plant. Here, controlled experiments were used assess translocation R. chinensis. The whole time-kinetics divided into two stages: rapid slower accumulation, processes fitted with linear model. concentration-dependent kinetics chara...

The caption for Figure 5 in the original publication incorrectly stated that data for complexes 1−4 were shown. It should refer only to data for complex 1. The corrected caption reads as follows: Figure 5. Bar graph showing the mitochondrial membrane polarization, determined by a reduction in red (FL2) fluorescence, by complex 1 against that of a negative and positive control (5 μM carbonyl cya...

The transport kinetics of the positively charged triphenylmethane dye, malachite green (MG(+)), across liposome bilayers effects the transport of monovalent inorganic cations when ionophores are present in the membrane. Three different types of ionophores characterized by different transport mechanisms have been studied. The ionophores are gramicidin A (gA) (a channel former), valinomycin (VAL)...

Antibiotic resistant and biofilm forming uropathogenic Enterobacteriaceae are rising. This study was conducted to evaluate the efflux pump plasmid mediated genes in ciprofloxacin (CIP) hospital acquired Escherichia coli Klebsiella pneumoniae. Also, assess anti-biofilm action of carbonyl cyanide m-chlorophenylhydrazone (CCCP). Uropathogenic E. K. pneumoniae isolates were collected from Mansoura ...

Posttetanic potentiation (PTP) is an essential aspect of synaptic transmission that arises from a persistent presynaptic [Ca2+]i following tetanic stimulation. At crayfish neuromuscular junctions, several inhibitors of mitochondrial Ca2+ uptake and release (tetraphenylphosphonium or TPP+, carbonyl cyanide m-chlorophenylhydrazone or CCCP, and ruthenium red) blocked PTP and the persistence of pre...

Poly(ethylene glycol) (PEG 8000) can induce cell-cell fusion of Mycoplasma capricolum cells, and it can promote the formation of intergeneric hybrids of various Mycoplasma, Acholeplasma and Spiroplasma species. The extent of fusion was quantitatively evaluated by following the dequenching of octadecylrhodamine fluorescent label incorporated into donor cell membranes after their incubation with ...

Lysosomes containing large amounts of the amino acid, cystine, were obtained from transformed, cultured, human lymphoblasts which had been exposed to cystine dimethyl ester. Lysosomal cystine efflux was greatly enhanced by exogenous ATP in cell lines from normal individuals. Cystine efflux was unresponsive to ATP in lysosomes from individuals with the disorder, cystinosis. Efflux of cystine fro...
