Human pluripotent stem cells (hPSCs) provide a promising platform to produce dendritic cell (DC) vaccine. To streamline the production process, we investigated a unique antigen-loading strategy that suits this novel platform. Specifically, we stably modified hPSCs using tumour antigen genes in the form of a full-length tumour antigen gene or an artificial tumour antigen epitope-coding minigene....
Common symptoms of upper respiratory infections, such as sore throat, cough, and inflammation, are often caused by bacteria, sometimes as a complication of virus infection. Extracts of Echinacea purpurea (Asteraceae) have been advocated traditionally for use by individuals suffering from these symptoms, although the underlying basis for the beneficial effects of Echinacea is not known. We hypot...
Immediate loading of threaded implants with a fixed provisional restoration at stage 1 surgery was evaluated in 10 consecutive patients. The patients selected had to be completely edentulous and have adequate bone for a minimum of 10-mm-long implants. A minimum of 10 implants were placed in each patient’s arch. A minimum of five implants were submerged initially for medicolegal reasons and allo...
Phenylarsine oxide (PAO) forms a stable ring complex with vicinal dithiols that can be reversed with 2,3-dimercaptopropanol (DMP) but not by dithiothreitol (DTT) or 2-mercaptoethanol (2-ME). PAO at 2 microM or higher inhibited heat shock protein 70 (HSP70) induction within minutes in cultured guinea pig gastric mucosal cells exposed to heat (43 degrees C) for 30 min. PAO did not affect the nucl...
Abstract T cell immunity to viruses and cancers is crucially dependent on the surface display of major histocompatibility complex class I (MHC-I) molecules selectively loaded with high affinity peptides. Peptide loading occurs in ER within a multimolecular assembly known as peptide (PLC). A critical component PLC tapasin, 45 kDa membrane glycoprotein whose absence expression stability MHC-I are...
This paper investigates the nature of the development of two-dimensional laminar flow of an incompressible fluid at the reversed stagnation-point. ”. In this study, we revisit the problem of reversed stagnation-point flow over a flat plate. Proudman and Johnson (1962) first studied the flow and obtained an asymptotic solution by neglecting the viscous terms. This is no true in neglecting the vi...
Mesoporous SBA-15 with different Fe2O3 loading were synthesized by an in-situ coating progress for removals of dichlorodiphenyltrichloroethane (DDT) and its derivatives, i.e., 1,1-dichloro-2,2-bis-(p-chlorophenyl)ethane (DDD) and 1,1-dichloro-2,2-bis-(4-chloro -phenyl) ethane (DDE). The results from XRD (X-ray diffractometer), TEM (transmission electron microscopy) indicated that the iron could...
the effect of repetitive electrical field stimulation and the response of the guinea-pig and rat ileal longitudinal muscle to single pulse stimulations was examined. single pulse field stimulation produced twitch contraction which was inhibited by repetitive field stimulation (10 hz, 40v, 0.5 msec for 5 m). this inhibition was largely, though never completely, reversed by naloxone. contractions...
Under physiological conditions bone defects often occur at mechanical load bearing sites and bone substitutes used for regeneration should be similarly subjected to mechanical loading stress. In this study, we investigated whether a novel heel-strike like mechanical loading method can be used as a complementary therapy to promote bone regeneration following bone substitute grafting. To test thi...
BACKGROUND Newly synthesised peptide-receptive major histocompatibility complex (MHC) class I molecules form a transient loading complex in the endoplasmic reticulum with the transporter associated with antigen processing (TAP) and a set of accessory proteins. Binding of peptide to the MHC class I molecule is necessary for dissociation of the MHC class I molecule from the complex with TAP, but ...
