Currently available therapies for the treatment of Alzheimer's disease (AD) consist of cholinesterase inhibitors (ChEIs), such as donepezil, and the N-methyl-D-aspartate receptor antagonist memantine. In December 2014, the US Food and Drug Administration approved Namzaric™, a once-daily, fixed-dose combination (FDC) of memantine extended-release (ER) and donepezil for patients with moderate-to-...

Follicular dendritic cell (FDC) sarcoma is rare and is classified either as conventional type or inflammatory pseudotumor (IPT)-like variant. Extranodal presentation is uncommon and nearly all gastrointestinal FDC tumors are of the conventional type. IPT-like variant tumors occur almost exclusively in the liver and spleen and are consistently associated with Epstein-Barr virus (EBV). Here we re...

Follicular dendritic cells (FDCs) are unique immune cells that contribute to the regulation of humoral immune responses. These cells are located in the B-cell follicles of secondary lymphoid tissues where they trap and retain antigens (Ags) in the form of highly immunogenic immune complexes (ICs) consisting of Ag plus specific antibody (Ab) and/or complement proteins. FDCs multimerize Ags and p...

OBJECTIVE The purpose of this study was to investigate the efficacy and safety of Fixed Dose Combination (FDC) of olanzapine 5 mg and fluoxetine 20 mg in Indian patients with severe or treatment resistant depression. DESIGN This was an open, non-comparative study of seven weeks duration with an initial placebo run in period of one week. METHOD One hundred and fifty three patients were enrol...

BACKGROUND More than 20 genes have been reported to cause idiopathic and familial dilated cardiomyopathy (IDC/FDC), but the frequency of genetic causation remains poorly understood. METHODS AND RESULTS Blood samples were collected and DNA prepared from 313 patients, 183 with FDC and 130 with IDC. Genomic DNA underwent bidirectional sequencing of six genes, and mutation carriers were followed ...

Idiopathic dilated cardiomyopathy (IDC) is characterized by left ventricular dilatation and systolic dysfunction after known causes have been excluded. Idiopathic dilated cardiomyopathy occurring in families, or familial dilated cardiomyopathy (FDC), may occur in 20% to 50% of IDC cases. Sixteen genes have been shown to cause autosomal dominant FDC, but collectively may account for only a fract...

The macrophage colony-stimulating factor (M-CSF) regulates proliferation and differentiation of cells belonging to the monocytic lineage. We have investigated the nature and origin of the proliferation and differentiation signals derived from the M-CSF receptor (Fms) by mutating Fms at the four tyrosine autophosphorylation sites and examining their biological effects in an FDC-P1 clone. Wild-ty...

Using an active, HAI epitope-tagged form of the murine erythropoietin (EPO) receptor and via direct coimmunoprecipitation, the p85 regulatory subunit of phosphatidyl inositol-3 kinase (p85/PI3-K) is shown to associate with the EPO receptor in transfected FDC-P1 cell lines. Coimmunoprecipitation of p85 with epitope-tagged EPO receptors was observed initially in FDC-HER cells labeled metabolicall...

Mevalonate is the precursor of a number of different products poten tially required for the growth of cells, including the prenyiated oncoprotein Ras. To determine whether inhibition of mevalonate metabolism would selectively block proliferation of Ras-transformed cells, 6-fluoromevalonate (Fmev), an inhibitor of diphosphomevalonate decarboxylase, was used to block the synthesis of prenyl-deriv...
