Collection, Mission, Action. Bridge the Museum to the World.
Steven Engelsman 한국박물관학회 박물관학보 10 Pages
and the world? Are museums ivory towers? I find it hard to believe, celtainly here in the US. You all know your external stakeholders, don’t you, and your trustees, they do represent the outside world, don’t they? %이at has also puzzled me was that notion of bridge to ?1e world. It’s so unidirectional: from the museum to the world rather than between the two of them. Why is that so? Is there a feeling amongst museums that they will have to act now, otherwise become too isolated and obsolete? -

During depolarization, extrusion of Ca2 from sarcoplasmic reticulum through forward-mode Na-Ca2 exchange was studied in the rat ventricular myocytes patch-clamped in whole-cell configuration. In order to confine the Ca2 responses in a micro-domain by limiting the Ca2 diffusion time, rat ventricular myocytes were dialyzed with high (14 mM) EGTA. K current was suppressed by substituting KCl with 105 mM CsCl and 20 mM TEA in the pipette filling solution... -

In macrophages, lipopolysaccharide (LPS) alone or in combination with interferon-γ (IFN-γ) has been shown to release a nitric oxide (NO) through the increase of the transcription of the inducible nitric oxide synthase (iNOS) gene. To investigate the exact intracellular signaling pathway of the regulation of iNOS gene transcription by LPS plus IFN-γ, the effects of protein tyrosine kinase (PTK) inhibitor and protein kinase C (PKC) inhibitors on NO production, iNOS mRNA expression, nuclear... -

To learn the developmental changes in intrinsic electrophysiological properties of the second order taste neurons, whole cell recordings from the developing nucleus of the solitary tract neurons were done in brainstem slices of postnatal rats. Rats aged from postnatal 0 to 21 days (P0-P21) were used, being divided into 3 age groups: postnatal first week (P0-P7 days), second week (P8-P14 days), and third week (P15-P21 days). Slices containing gustatory NTS were cut horizontally in the thickness... -

Glutamate and γ-aminobutyric acid (GABA) are major excitatory and inhibitory neurotransmitters in the vertebrate retina, respectively. Using the whole-cell patch clamp technique and a rapid solution changer, glutamate and GABA receptors have been extensively investigated in carp retina. Glutamate receptors on both horizontal and amacrine cells may be an AMPA preferring subtype, which predominantly consists of flop splice variants. GABAA and GABAC receptors coexist in bipolar cells and they... -

Pulmonary blood vessels with diameters of 200∼400 μm produce considerably more force in response to vasoconstrictor drugs than those which are either smaller or larger. We have therefore investigated whether or not hypoxic pulmonary vasoconstriction (HPV) is more powerful in vessels of these diameters. We have also looked at the possibility that vessels from different regions of the lung respond differently. To do this we have grouped vessels according to their location within the lung as... -

Recent reports revealed that the Na-Ca2 exchangers and feet structures of sarcoplasmic reticulum(SR) are located in close vicinity in the specific compartment. Therefore, we investigated the possibility that the Na-Ca2 exchanger may decrease the tension development by transporting the Ca2 out of the cell right after it released from SR, on the basis of this anatomical proximity. We exammined the negative force-frequency relationship of the developed tension in... -

Both M1 and M2 muscarinic receptors contain a triplet of amino acid residues consisting of leucine (L), tyrosine (Y) and threonine (T) at C-terminus ends of the second putative transmembrane domains. This triplet is repeated as LYT-LYT in M2 receptors at the interface between the second transmembrane domain and the first extracellular loop. Interestingly, however, it is repeated in a transposed fashion (LYT-TYL) in the sequence of M1 receptors. In this work, we employed site-directed mutagenesis... -

In the present study, we observed change in intracellular Ca2+([Ca2+]i) as measured with the fluorescent Ca2+-indicator fura-2 in association with force development of the rat basilar arteries during activation byK+ depolarizing solution and U46619, a thromboxane analogue, in the absence and the presence of calcitonin-gent related peptide (CGRP). CGRP (30 and 100 nM) caused a concentration-dependent inhibition of U46619-induced contraction with decrease in [Ca2+]i, whereas it did not exert any...
