Loss-of-function mutations in the potassium-chloride cotransporter KCC3 lead to Andermann syndrome, a severe sensorimotor neuropathy characterized by areflexia, amyotrophy and locomotor abnormalities. The molecular events responsible for axonal loss remain poorly understood. Here, we establish that global or neuron-specific KCC3 loss-of-function in mice leads to early neuromuscular junction (NMJ) abnormalities and muscular atrophy that are consistent with the pre-synaptic neurotransmission defects observed in patients...

OBJECTIVE: Despite the cost saving role of generic anti-epileptic drugs (AEDs), debate exists as to whether generic substitution of branded AEDs may lead to therapeutic failure and increased toxicity. This study compared adverse event (AE) reporting rates for brand vs. authorized generic (AG) vs. generic AEDs. Since AGs are pharmaceutically identical to brand but perceived as generics, the generic vs. AG comparison minimized potential bias against generics. METHODS: Events reported to the U...

The emerging micro-organic pollutants (EMOPs) cannot be effectively removed by conventional wastewater treatment processes. In this paper, the most commonly detected EMOPs in the effluent of wastewater treatment plants, including trimethoprim, sulfamethoxazole, carbamazepine, diclofenac, triclosan and methyl 3,5-dichloro-4-hydroxybenzoate, were selected and used to acclimate activated sludge respectively, to improve the performance of biological treatment for the removal of EMOPs from wastewater. The results showed that the acclimation of activated sludge can significantly enhance the removal of trimethoprim, sulfamethoxazole, diclofenac, triclosan and methyl 3,5-dichloro-4-hydroxybenzoate, but slightly improve the degradation of carbamazepine, which is more difficult to biodegrade...

PURPOSE: From our current understanding, the association between the human leukocyte antigen (HLA), HLA-B*1502, and carbamazepine(CBZ)-induced Stevens-Jonson syndrome and toxic epidermal necrolysis (SJS/TEN) in the Asian population is quite clear. However the relationship between other HLA-B alleles and CBZ-induced severe cutaneous adverse drug reactions (SCADRs) remains unclear. We aimed to identify other non-HLA-B*1502 alleles in patients with CBZ-induced SCADRs through a meta-analysis...

This paper applied the response surface methodology (RSM) to optimizing a novel Fe(II)/citrate/UV/PMS process in the degradation of a model micropollutant, carbamazepine (CBZ), a persistent emerging contaminant frequently detected in surface water and groundwater. The experimental conditions in terms of two responses, CBZ removal efficiency (Y1) and cost per unit CBZ removal (Y2), were optimized by the central composite design (CCD) in RSM. Modeling data exhibited that the optimum condition resulting in the lowest Y2 while achieving >70% of Y1 was at a UV dose of 265...

Human neural stem cells have been proposed as an in vitro model to predict neurotoxicity. In this study, the potential of in vitro cultures of human-derived neurospheres to predict the effects of various anti-epileptic drugs (sodium valproate, phenytoin, carbamazepine and phenobarbitone) was evaluated. In general, these drugs had no significant effects on cell viability, total cellular protein, and neuronal process length at low doses, but at high doses these parameters were reduced significantly. Therapeutic doses of sodium valproate and phenytoin had a clear effect on neurosphere size and cell migration, with a significant reduction in both parameters when compared with the control group...

Considerable interest has been given to using nanofiltration (NF) in lieu of reverse osmosis for water reclamation schemes due to lower energy consumption, higher flux rates while ensuring good micropollutants rejection. The application NF results in the generation of a large concentrated waste stream. Treatment of the concentrate is a major hurdle for the implementation of membrane technologies since the concentrate is usually unusable due to a large pollutants content. This work focuses on the application of ozonation as pretreatment of urban NF concentrates, the generation of transformation products and their relative toxicity...

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis are two rare but life-threatening diseases characterized by detachment of epidermis, bullous skin lesions and mucous membrane erosions. Anti-epileptic drugs are highly suspected to be the causative agents. Although carbamazepine (CBZ) is the most associated anti-epileptic drug, oxcarbazepine (OXC), which is a monohydrated derivative of CBZ, is proposed to be safer because of the different metabolism of the two drugs. Herein, we report a case of SJS induced by oxcarbazepine...
