The congenital disorder of glycosylation (CDG) due to phosphomannomutase 2 deficiency (PMM2-CDG), the most common N-glycosylation disorder, is a multisystem disease for which no effective treatment is available. The recent functional characterization of disease-causing mutations described in patients with PMM2-CDG led to the idea of a therapeutic strategy involving pharmacological chaperones (PC) to rescue PMM2 loss-of-function mutations. The present work describes the high-throughput screening, by differential scanning fluorimetry, of 10,000 low molecular weight compounds from a commercial library, to search for possible PCs for the enzyme PMM2...

BACKGROUND: We have previously reported on a novel organ-specific immunomodifying therapy that provides protection from early allograft rejection in the absence of systemic immunosuppressive drugs. This novel therapy is a nano-barrier membrane called ImmunoCloak, consisting of a matrix of laminin, proteoglycans, fibronectin and collagens. The membrane "immunocloaks" the luminal surfaces within the renal vasculature by covering the point of contact between donor vascular endothelial cells and the recipient's immune cells; without adversely affecting renal function...

Transcranial magnetic stimulation (TMS) has recently been investigated as a possible adjuvant treatment for many neuropsychiatric disorders, and has already been approved for the treatment of drug-resistant depression in the United States and in Brazil, among other countries. Although its use in other neuropsychiatric disorders is still largely experimental, many physicians have been using it as an off-label add-on therapy for various disorders. More recently, another technique, transcranial direct current stimulation (tDCS), has also become available as a much cheaper and portable alternative to TMS, although its mechanisms of action are different from those of TMS...

The bioactivity of a newly registered annonin-based formulation (Anosom® 1 EC) was investigated for use against the fall armyworm Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), both singly and mixed with a limonoid-based formulation (Azamax® 1.2 EC) using dietary exposure bioassays. Anosom® 1 EC caused significant mortality in S. frugiperda larvae exposed to treated artificial media, with the activity level dependent on both the concentration and the exposure time. In addition to exhibiting acute toxicity, this formulation (tested at LC50) also caused growth inhibition of S...
