A C-linked isostere of beta-D-galactosylated hydroxynorvaline has been prepared in eight steps from per-O-benzylated galactopyranolactone. Addition of a homoallylic Grignard reagent to the lactone, reduction of the resulting hemiacetal with triethylsilane, and a Wittig reaction with Garner's aldehyde were key steps in this synthesis. The C-linked building block was then incorporated at position 26

During the 18-yr period 1976-93, a population-based series of 1586 adults with suspected or confirmed hematological malignancies were successfully cytogenetically investigated at a single center. Eighty-six cases were excluded due to unretrievable medical records or if analyzed only in remission or at relapse. The remaining 1500 medical records were reviewed regarding morphology and clinical param

A p-compact group, as defined by Dwyer and Wilkerson, is a purely homotopically defined p-local analog of a compact Lie group. It has long been the hope, and later the conjecture, that these objects should have a classification similar to the classification of compact Lie groups. In this paper we finish the proof of this conjecture, for p an odd prime, proving that there is a one-to-one correspond

We describe a simple, yet practical and precise. way of measuring sorption isotherms with each sample in its own glass jar with a saturated salt solution. The measurements are done with below-balance weighing and with the sample kept inside the closed jar during the whole measurement period, providing constant relative humidity (RH) conditions. The technique has been tested on microcrystalline cel

The geography of the creative class and its impact on regional development has been debated for some years. While the ideas of Richard Florida have permeated local and regional planning strategies in most parts of the Western world, critiques have been numerous. Florida's 3T's (technology, talent, and tolerance) have been adopted without considering whether the theory fits into the settings of a s

Binding of short chain phosphatidylserine (C6PS) enhances the proteolytic activity of factor X-a by 60-fold (Koppaka, V., Wang, J., Banerjee, M., and Lentz, B. R. (1996) Biochemistry 35, 7482-7491). In the present study, we locate three C6PS binding sites to different domains of factor X-a using a combination of activity, circular dichroism, fluorescence, and equilibrium dialysis measurements on p

Background. Many individuals are infected with the bacterium Helicobacter pylori. Some develop ulcers or mucosal atrophy. Aims. To correlate the histological characteristics of the H. pylori-induced gastritis to the immunoblot pattern of the H. pylori infection and to compare the presence of H. pylori bacteria in tissue specimens with ELISA serology and immunoblot analysis. Methods. One hundred an

The authors investigated in a rat model the efficacy of magnetic resonance imaging (MRI) contrast media for evaluating the liver in conditions of acute biliary obstruction. Two liver-specific MRI contrast media, Cr-DEHIDA and Mn-DPDP, and the nonspecific agent Gd-DTPA were studied in normal rats and in rats whose bile ducts had been ligated before administration of the contrast medium. Images were

The European Study on the Clinical Outcomes and Resource Utilization associated with Haemophilia Care was designed to compare various health outcomes associated with on-demand and prophylactic factor substitution methods in European haemophilia patients. While the primary objective of this research is to conduct an economic analysis, an important component of this study is to evaluate quality-of-l

We evaluated the effects of Plasmodium relictum (lineage P-SGS1), which is a host generalist, to five species of passerine birds. Light infection of P. relictum was isolated from a naturally infected adult reed warbler Acrocephalus scirpaceus. The parasites were inoculated to naive juveniles of the chaffinch Fringilla coelebs, common crossbill Loxia curvirostra, house sparrow Passer domesticus. si

The gene for protein D, a membrane-associated protein with specific affinity for human immunoglobulin D, was cloned from a nontypeable strain of Haemophilus influenzae. The gene was expressed in Escherichia coli from an endogenous promoter, and the gene product has an apparent molecular weight equal to that of H. influenzae protein D (42,000). The complete nucleotide sequence of the gene for prote

The aim: To record blood flow velocimetry in the fetal superior mesenteric artery in normal pregnancy and to evaluate if blood flow recordings in the vessel might predict adverse outcome in high-risk pregnancy. Methods: The fetal superior mesenteric artery blood velocimetry was recorded in a cross sectional manner in 75 normal pregnancies between 27 and 41 weeks of gestation. Reference curves were

The oral, pharyngeal, and esophageal stages of swallowing were evaluated in 8 patients with recessively or dominantly inherited pure sensory ataxia. Six patients had swallowing difficulties: solid bolus obstruction, coughs during eating, and choking episodes. One patient had chronic bronchitis and another had recurrent pneumonia. The patients underwent a biphasic radiological barium swallow, inclu

The stochastic Lagrange wave model is a realistic alternative to the Gaussian linear wave model, which has been successfully used in ocean engineering for more than half a century. This paper presents exact slope distributions and other characteristic distributions at level crossings for symmetric and asymmetric Lagrange space and time waves. These distributions are given as expectations in

Molecular factors control the developmental ingrowth of axons to the tooth pulp. Here we examine the ability of pulpal cells to induce neurite outgrowth from neonatal rat trigeminal neurones (TGNs) in vitro. We found that TGNs emitted neurites and formed networks of branches in relation to pulpal cells. Neurones co-cultured with a mixture of pulpal cells and 3T3 fibroblasts formed networks exclusi
