We have previously shown that hepatitis B virus (HBV) protein X (HBX), a regulatory protein of HBV, activates Stat1, leading to type I interferon (IFN) production. Type I IFN secreted from HBX-expressing hepatic cells enforces antiviral signals through its binding to the cognate type I IFN receptor. We therefore investigated how cells handle this detrimental situation. Interestingly, compared t...

PURPOSE Attenuation correction (AC) based on low-dose computed tomography (CT) could be more accurate in brain single-photon emission computed tomography (SPECT) than the widely used Chang method, and, therefore, has the potential to improve both semi-quantitative analysis and visual image interpretation. The present study evaluated CT-based AC for dopamine transporter SPECT with I-123-ioflupan...

This paper provides a complete theoretical treatment of the point-mass lens perturbed by constant external shear, often called the Chang-Refsdal lens. We show that simple invariants exist for the products of the (complex) positions of the four images, as well as moment sums of their signed magnifications. The image topographies and equations of the caustics and critical curves are also studied....

The addition of 0.08 M sucrose to a culture medium containing Chang-strain human liver cells causes intense cytoplasmic vacuolation. Electron microscopy of these cells grown inferritin, time-lapse cinematography, and radioautography reveal that the vacuoles arise by endocytosis and that the sucrose is taken into the cell and localized in the vacuoles. Tracer studies demonstrate that sucrose-(3)...

had left “ an extraordinary impression” during his weeklong visit to the United States. “ We were both surprised at the degree of warmth arid enthusiasm among the people in welcoming the pope," the president said of his private White House talk with the pontiff. “ I had no idea it would be that enthusiastic.” Carter said he believes the pope's U.S. tour was “ one of the most dramatic and potent...

OBJECTIVE The radioactivity count distribution in the brain must be determined accurately to accurately measure cerebral blood flow (CBF). Scatter and attenuation are factors that compromise the accuracy of determining radioactivity counts in the brain. METHODS We compared regional CBF in patients by an autoradiographic method using N-isopropyl-p-[123I] iodoamphetamine when, first, attenuatio...

Previous research (e.g., Leung, Chang, & Hau, 2001; Yi & Chang, 2001) has shown that the astratified method with content blocking (STR_C) performed well in content balancing constrained computerized adaptive tests (CATs). It effectively reduced the exposure rates of highly discriminating items, produced more balanced item usage within a pool, and maintained measurement precision. This method, h...
