Clinical trials of radioimmunotherapy (RIT) of lymphoma have produced frequent tumor regressions and remissions, but it has been difficult to determine to what extent these tumor responses have been due to antibody-specific targeted radiation, nontargeted radiation, and/or cytotoxicity mediated by the carrier monoclonal antibody (MoAb). In this report, RIT was studied in athymic nude mice beari...

Cyclin genes and their products are important regulatory participants in the eukaryotic cell cycle. It is well established that cyclin B1 protein forms a complex with cyclin-dependent kinase 1 (CDK1), which, when activated, initiates mitosis. We have previously established that cyclin B1 gene expression is posttranscriptionally regulated in regenerating rat liver after 70% partial hepatectomy (...

In this paper we show that there is a Lipatov bound for the radius of convergence for superficially divergent one-particle irreducible Green functions in a renormalizable quantum field theory if there is such a bound for the superficially convergent ones. The radius of convergence turns out to be min{ρ, 1/b1}, where ρ is the bound on the convergent ones, the instanton radius, and b1 the first c...

The NS3 protein of hepatitis C virus subtype 1b (HCV-1b) isolates obtained from 89 patients with hepatocellular carcinoma (HCC) and 78 patients without HCC were analyzed. On the basis of the secondary structure of the amino-terminal 120 residues of NS3, HCV-1b isolates were classified into group A, group B, and an indeterminate group, each of which was further divided into a number of subgroups...

Although several cytokines and chemokines have been demonstrated to play pivotal roles in the pathophysiological conditions of atherosclerosis, few findings exist regarding the expression and function of cytokine-modulating molecules such as ephrin-Bs and their cognate receptors, EphBs, in human atherosclerosis. Therefore, in the present study, we screened novel genes modulating atherogenesis b...

We prove the consistency of: if B1, B2 are Boolean algebras satisfying the c.c.c. and the 20 -c.c. respectively then B1 × B2 satisfies the 20 -c.c. We start with a universe with a Ramsey cardinal (less suffice).

In most Japanese populations of dojo loach (Misgurnus anguillicaudatus), gonochoristic diploids genetically diversified groups (A and B, further subdivided into B1 B2) are present, whereas unisexual clonal lineages inhabit certain localities in the Hokkaido Ishikawa Prefectures Japan. Through a series genetic studies including DNA markers, loaches were deemed to originate from hybridization eve...

Vitamin B1, or thiamin, can limit primary productivity in marine environments, however the major marine environmental sources of this essential coenzyme remain largely unknown. Vitamin B1 can only be produced by organisms that possess its complete synthesis pathway, while other organisms meet their cellular B1 quota by scavenging the coenzyme from exogenous sources. Due to high bacterial cell d...

Introduction In high field MRI, the increased interactions between the electromagnetic waves and the biological tissues may give rise to heat and thermal hazards. This is clearly apparent for multi-transmit array applications where the electromagnetic fields are heavily manipulated in the subject to be imaged. In this work we provide complete 3D predictions of the B1 + fields, MRI images, energ...
