Anionic urea-based dimeric (gemini) surfactants derived from the amino acids L-cystine, D-cystine and DL-cystine, as well as monomeric surfactants derived from L-cysteine, L-methionine and L-cysteic acid were synthesized and their solution properties characterized by electrical conductivity, equilibrium surface tension, and

A group of biofilm-producing bacteria isolated from patients with urinary tract infections was evaluated, identifying the main factors contributing to biofilm formation. Among the 156 isolates, 58 (37.2%) were biofilm producers. The bacterial species (P<0.001), together with patient's gender (P

The mutations responsible for cystinosis in South African patients are currently unknown. A pertinent question is whether they are similar to those described elsewhere in the world. Children who were being managed for cystinosis in the Western Cape Province of

The use of glutathione (GSH) and sulfate for the detoxification of paracetamol (acetaminophen, APAP) could occur at the expense of the physiological uses of cysteine (Cys). Indeed GSH and sulfate both originate from Cys. Significant APAP-induced Cys loss could generate
Extrasynaptic glutamate release through cystine/glutamate antiporter contributes to ischemic damage.

During brain ischemia, an excessive release of glutamate triggers neuronal death through the overactivation of NMDA receptors (NMDARs); however, the underlying pathways that alter glutamate homeostasis and whether synaptic or extrasynaptic sites are responsible for excess glutamate remain controversial.
