The glial cells missing (gcm) regulatory gene of the sea urchin Strongylocentrotus purpuratus is first expressed in veg2 daughter cells as the genomic target of late cleavage stage Delta-Notch signaling from the skeletogenic mesoderm precursors. Gcm is required in veg2 progeny during late cleavages for the early phase of pigment cell precursor specification. Here we report on a later acting cis...

Background: Differentiating oligodendrocyte precursor cells (OPCs) into oligodendrocytes could be improved by inhibiting signaling pathways such as Wnt and Notch. 9-cis-retinoic acid (9-cis-RA) and 1,25-dihydroxyvitamin D3 (1,25[OH]2D3) can ameliorate oligodendrogenesis. We investigated whether they could increase oligodendrogenesis by inhibiting the Wnt and Notch signaling pathways.Methods: Co...

The effects of retinoic acid (RA) isomers (all-trans-RA and 9-cis-RA) on the appearance of uncoupling protein (UCP; thermogenin), the only unequivocal molecular marker of the brown adipocyte differentiated phenotype, have been investigated in primary cultures of brown adipocytes, in the brown adipocyte cell line HIB 1B and directly in intact mice. The results obtained with cultured cells indica...

abstract introduction : conjugated linoleic acid (cla) has been shown to positively influence on calcium and bone metabolism in experimental animals and cell culture, but there are limited human data available. material and methods : this double-blind, placebo-controlled trial study was done on 76 healthy post-menopausal women (aged 55.1) which randomly assigned to receive daily four cla capsul...

Objective To assess whether any alteration of B-cell subset distribution and/or the cytokine production capacities of B cells could be associated with any stage of MS and could be predictive of MS evolution. Methods We prospectively enrolled radiologically isolated syndrome (RIS), clinically isolated syndrome (CIS), naive patients with relapsing remitting MS (RRMS) of any disease modifying dr...

CIS (Cu-InSe) thin films were prepared onto glass substrate by the two stage process—generally called bilayer process. At first, Cu layer was deposited onto glass substrate by electron beam evaporation technique and then InSe single layer was deposited on the resulting Cu layer to produce CIS thin film. XRD (X-ray diffraction) analysis revealed that deposited film has an amorphous nature. Elect...
