Two 70-kD polypeptides, B3 and B4, are present in equivalent concentrations in the nucleus and cytoplasm of Xenopus oocytes. The objectives of this study were to determine if they (a) are members of the 70-kD family of heat shock proteins, and (b) recycle between the nuclear and cytoplasmic compartments. Evidence based on high-affinity binding to ATP, cross-reactivity of B3/B4-specific antibodi...

Xenopus egg extracts which assemble replication competent nuclei in vitro were depleted of lamin B3 using monoclonal antibody L6 5D5 linked to paramagnetic beads. After depletion, the extracts were still capable of assembling nuclei around demembranated sperm heads. Using field emission in lens scanning electron microscopy (FEISEM) we show that most nuclei assembled in lamin B3-depleted extract...

BACKGROUND The purpose of this study was to correlate the Ki67 labelling index (LI) with the Masaoka classification and the new WHO-classification in type B3 / C thymomas. PATIENTS AND METHODS Fourteen patients with type B3 / C thymomas were evaluated, and archived specimens were histologically reclassified according to Masaoka staging, the new WHO classification and the Ki-67 LI in a retrosp...

BACKGROUND Prior reported cases of stillbirth and neonates infected with enteroviruses suggest transplacental infection. We present a case of fetal infection with coxsackievirus B3, diagnosed antenatally and resulting in live birth. CASE A pregnant woman presented at 26 weeks with fetal tachycardia and non-immune hydrops fetalis. Coxsackievirus B3 was cultured from amniotic fluid. Maternal an...

Given three mutually tangent circles with bends (or the reciprocal of the radius) a, b and c respectively, an important quantity associated with the triple is the value 〈a, b, c〉 := ab + ac + bc. In this note we show in the case when a central circle with bend b0 is “surrounded” by four circles, i.e., a flower with four petals, with bends b1, b2, b3, b4 that either p 〈b0, b1, b2〉 + p 〈b0, b3, b...

We investigated the antimicrobial activity of four polymyxin B components, B1, B2, B3, and isoleucine (Ile)-B1, individually and in combination. B3 was the most active agent against all organisms tested except Acinetobacter baumannii, for which Ile-B1 was most active. One combination met the criteria for synergy, B3 plus Ile-B1. No combinations exhibited antagonism. The dominant components of p...

To investigate whether a specific isotype of tubulin is involved in flagellar motility, we have developed and screened a panel of monoclonal antibodies (mAb) generated against sea urchin sperm axonemal proteins. Antibodies were selected for their ability to block the motility of permeabilized sperm models. The antitubulin mAb B3 completely inhibited, at low concentrations, the flagellar motilit...
