An initial mapping analysis of growth and reproduction complex (grc) and grc+ genomic DNA identified several restriction fragment length polymorphisms specific for the grc region of the MHC. To analyze further the genomic organization and structure of the grc, a cosmid library was constructed from a grc+-bearing strain (R21). One cosmid cluster,(More)
Insulin-degrading activity in mononuclear (MN) and polymorphonuclear (PMN) fractions of circulating leukocytes obtained from 7 nondiabetic and 13 insulin-dependent diabetic subjects was studied. Insulin-degrading activity in both MN and PMN fractions was activated by reduced glutathione and was inhibited completely by N-ethylmaleimide. Both fractions had(More)
A series of 85 fine-needle aspiration (FNA) biopsies from orbital space occupying lesions of 82 patients are reviewed. A total of 32 benign lesions and 49 malignant lesions were conclusively diagnosed. In two cases the aspirates were insufficient for diagnosis. Of two cases, which were cytologically suspicious for lymphoma, a repeat FNA resulted in a(More)
The very recently observed D∗ sJ (2317) meson is described as a quasi-bound scalar cs̄ state in a unitarized meson model, owing its existence to the strong P0 OZI-allowed coupling to the nearby S-wave DK threshold. By the same mechanism, a scalar D∗ 0(2100– 2300) resonance is predicted above the Dπ threshold. These scalars are the charmed cousins of the(More)
We present the clinical, radiological, and pathological findings in an elderly man who developed a progressive superior orbital fissure syndrome due to idiopathic hypertrophic cranial pachymeningitis. The unique aspect of this case concerned the increased density of the sphenoid ridge and lateral orbital wall observed by using computed tomography, and the(More)
Fine-needle aspiration biopsy (FNAB) under ultrasonographic or computerized tomographic guidance is a useful diagnostic procedure for hepatic neoplasms. However, cytologic criteria alone may not allow for the distinction of hepatocellular carcinomas (HCC) from cholangiocarcinomas (CC) and metastatic adenocarcinomas (MA). In an effort to refine the FNAB(More)
Resonances appearing in hadronic scattering processes are described by a two-phase model. In the one phase, scattering products are observed, whereas the other phase describes confinement. A so-called “Resonance-Spectrum Expansion” is derived, containing expressions that resemble Breit-Wigner formulae. This method also provides a straightforward explanation(More)
We study Sand P -wave ππ and Kπ distributions for the three-body production processes J/ψ → ωπ+π−, D+ → K−π+π+, D+ → K+π+π−, and D+ s → K +π+π−, by applying the Resonance-Spectrum Expansion to the two-body subamplitudes. The results are compared to the corresponding signals reported by the BES, E791 and FOCUS collaborations. We find that the studied Sand P(More)
