Band 3 (anion-exchange protein 1-[AE1]) is the major integral membrane protein of human erythrocytes and links the membrane to the underlying cytoskeleton via high-affinity binding to ankyrin. It is unclear whether other cytoskeletal proteins participate in strengthening the ankyrin-band 3 linkage, but a putative role for protein 4.2 (P4.2) has been proposed based on the increased osmotic fragi...

The hypothesis that the cyanomethyl anion CH2CN is responsible for the relatively narrow diffuse interstellar band (DIB) at 8037.8± 0.15 Å is examined with reference to new observational data. The 00 absorption band arising from the B1 − X̃ 1A′ transition from the electronic ground state to the first dipole-bound state of the anion is calculated for a rotational temperature of 2.7 K using litera...

Trial wave functions including angular momentum projection and deformation with central Jastrow and linear-type correlations are calculated to study the ground state rotational band of the Ne, Mg, Si, S, and Ar nuclei and the ground state of Ca. A systematic analysis of the competition among different correlation mechanisms on the binding energy and other properties such as the root mean square...

An increasing concern has been given to the rotation stability of the knee in the setting of an anterior cruciate ligament (ACL) reconstruction. This growing interest stems from a better understanding of the rotational stability of the knee afforded by the identification of the anterolateral ligament. Previously, a residual abnormal pivot-shift test had been found after an anatomic single-band ...

We describe a case of rotational dislocation of the proximal interphalangeal joint of the ring finger. This injury was not initially appreciated and therefore closed reduction failed. The clinical findings included puckering of the skin on the dorsum of the joint and rotational incongruity on radiographs. At open reduction there was interposition of the lateral band. Identification of the patho...

A transient infrared absorption spectrum of gaseous ClCS was detected with a step-scan Fourier-transform spectrometer coupled with a multipass absorption cell. ClCS was produced upon irradiating a flowing mixture of Cl2CS and N2 or CO2 with a KrF excimer laser at 248 nm. A transient band in the region of 1160-1220 cm-1, which diminished on prolonged reaction, is assigned to the C-S stretching (...

Moderate resolution spectra of the 030 band of NH2 near 6300 Å were recorded in Comet Hale-Bopp near 2.6 and 1.0 AU with the HYDRA array spectrometer on the WIYN telescope. The spectra from beyond the collision sphere were examined with respect to the relative rotational energy distributions in NH2. The relative rotational profiles could be consistently fit at both heliocentric positions by a p...

The role of ankyrin in the formation and stabilization of the spectrin-based skeletal meshwork and of band 3 oligomers was studied by characterizing, in nb/nb mouse red cells, the effect of ankyrin deficiency on skeletal ultrastructure, band 3-skeleton associations, and band 3 oligomeric states. Despite severe ankyrin deficiency, nb/nb mouse red cell skeletal components formed a relatively unif...
