Multidrug-resistant cancer cells display elevated levels of glucosylceramide (Lavie, Y., Cao, H. T., Volner, A., Lucci, A., Han, T. Y., Geffen, V., Giuliano, A. E., and Cabot, M. C. (1997) J. Biol. Chem. 272, 1682-1687). In this study, we have introduced glucosylceramide synthase (GCS) into wild type MCF-7 breast cancer cells using a retroviral tetracycline-on expression system, and we develope...
OBJECTIVE To compare the value of Glasgow coma scale (GCS) and cerebral state index (CSI) on predicting hospital discharge status of acute brain-injured patients. METHODS In 60 brain-injured patients who did not receive sedatives, GCS and CSI were measured daily during the first 10 days of hospitalization. The outcome of prognostic cut-off points was calculated by GCS and CSI using receiver o...
OBJECTIVE Glucocorticoids (GCs) alter bone strength such that patients receiving these medications have a high rate of fragility-related fractures. The purpose of this study was to assess whether concurrent treatment with GCs (prednisolone) and risedronate (an aminobisphosphonate) would prevent the reduction in bone strength induced by GCs, in a mouse model of GC-induced bone loss and in patien...
BACKGROUND One of the settings where deep vein thrombosis (DVT) in the lower limb and pelvic veins occurs is in hospital with prolonged immobilisation of patients for various surgical and medical illnesses. Using graduated compression stockings (GCS) in these patients has been proposed to decrease the risk of DVT. This is an update of a Cochrane review first published in 2000 and updated in 200...
Rat hepatocytes cultured for 3 days in basal medium expressed low levels of cysteine dioxygenase (CDO) and high levels of gamma-glutamylcysteine synthetase (GCS). When the medium was supplemented with 2 mmol/l methionine or cysteine, CDO activity and CDO protein increased by >10-fold and CDO mRNA increased by 1.5- or 3.2-fold. In contrast, GCS activity decreased to 51 or 29% of basal, GCS heavy...
Glucocorticoids (GCs) display both protective and destructive effects in the nervous system. In excess, GCs produce neuronal damage after stress or brain injury; however, the neuroprotective effects of adrenal steroids also have been reported. The mechanisms that account for the positive actions are not well understood. Here we report that GCs can selectively activate Trk receptor tyrosine kina...
We examined whether coupling between neighboring -type ganglion cells ( -GCs) in the rabbit retina underlies their synchronous spike activity. Simultaneous recordings were made from arrays of -GCs to determine the synchrony of both spontaneous and light-evoked spike activity. One cell within each array was then injected with the biotinylated tracer Neurobiotin to determine which of the cells we...
We have obtained Keck spectra of six candidate globular clusters (GCs) in the dynamically young elliptical galaxy NGC 3610, supplementing our previous Keck spectra of eight confirmed GCs (Strader et al. 2003). Five of our new candidates are confirmed to be GCs. Of the thirteen GCs, eleven are located within the K band effective radius of 7 kpc. Two of these thirteen clusters are found to be you...
Cerebellar granule cells (GCs), the smallest neurons in the brain, have on average four short dendrites that receive high-frequency mossy fiber inputs conveying sensory information. The short length of the dendrites suggests that GCs are electrotonically compact allowing unfiltered integration of dendritic inputs. The small average diameter of the dendrites (~0.7 µm), however, argues for dendri...
Robust incorporation of new principal cells into pre-existing circuitry in the adult mammalian brain is unique to the hippocampal dentate gyrus (DG). We asked if adult-born granule cells (GCs) might act to regulate processing within the DG by modulating the substantially more abundant mature GCs. Optogenetic stimulation of a cohort of young adult-born GCs (0 to 7 weeks post-mitosis) revealed th...
