Cannabidiol counters the effects of a dominant-negative pathogenic Kv7.2 variant.

Epilepsy and neurodevelopmental disorders can arise from pathogenic variants of KCNQ (Kv7) channels. A patient with developmental and epileptic encephalopathy exhibited an in-frame deletion of histidine 260 on Kv7.2.

High dose folic acid supplementation of rats alters synaptic transmission and seizure susceptibility in offspring.

Maternal folic acid supplementation is essential to reduce the risk of neural tube defects. We hypothesize that high levels of folic acid throughout gestation may produce neural networks more susceptible to seizure in offspring. We hence administered large doses of folic acid to rats before and during gestation and found their offspring had a 42% decrease in their seizure threshold.

Meta-analysis of randomized, controlled trials comparing particular doses of griseofulvin and terbinafine for the treatment of tinea capitis.

Two oral antifungal agents, griseofulvin and terbinafine, have regulatory approval in the United States, but it is unknown whether one has superior overall efficacy. Genus-specific differences in efficacy are believed to exist for the two agents. It is not clear at what doses and durations of treatment these differences apply.

Evidence-based optimal fluconazole dosing regimen for onychomycosis treatment.

Background: Fluconazole could be an alternative to terbinafine and itraconazole for onychomycosis treatment. However, it is difficult to determine the optimal dosing regimen due to the variability in causative agents, dosing regimens and cure rates in clinical trials. By restricting the data to dermatophyte onychomycosis, we aimed to identify an optimal fluconazole dosing regimen.

Systematic review of nondermatophyte mold onychomycosis: diagnosis, clinical types, epidemiology, and treatment.

Nondermatophyte mold (NDM) onychomycosis is difficult to diagnose given that NDMs are common contaminants of the nails and of the mycology laboratory. Diagnostic criteria and definition of cure are inconsistent between studies, which may affect the quality of published data. We identified 6 major criteria used in the literature: identification of the NDM in the nail by microscopy (using potassium hydroxide preparation), isolation in culture, repeated isolation in culture, inoculum counting, failure to isolate a dermatophyte in culture, and histology.

Puma is a dominant regulator of oxidative stress induced Bax activation and neuronal apoptosis.

Oxidative stress has been implicated as a key trigger of neuronal apoptosis in stroke and neurodegenerative conditions such as Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis. The Bcl-2 homology 3 (BH3)-only subfamily of Bcl-2 genes consists of multiple members that can be activated in a cell-type- and stimulus-specific manner to promote cell death. In the present study, we demonstrate that, in cortical neurons, oxidative stress induces the expression of the BH3-only members Bim, Noxa, and Puma.
