Great Expectations: The role of the wig stylist (sheitel macher) in orthodox Jewish salons

Wigs are curious liminal objects that hover somewhere between the categories of prosthesis and clothing and offer a variety of possibilities from transformation to hair substitution, covering and disguise. In this article I focus on the particular demands and expectations placed upon the sheitel (Yiddish term for wig) worn by increasing numbers of married Jewish women who identify as frum (Torah-observant). Based on research in Jewish wig salons in Britain and the United States and on Jewish online forums, internet discussions and blogs with a wider geographic reach, this article sets out to show the complex web of material, social, emotional, aesthetic and moral concerns that cluster around the sheitel and to highlight the role of the sheitel macher (wig stylist) in managing these anxieties and expectations. If all wigs are fraught with expectations in terms of their capacity to enable successful social performances, sheitels, it is argued, carry a particularly high burden of expectations owing to their contested and multivalent role as material embodiments of religious commitment, social status and fashion competence and owing to the ambivalent feelings many Jewish women have towards their wigs

Preparation of 3'-phosphoadenylyl sulfate in substrate quantities using mastocytoma enzymes

A method was developed for the enzymic preparation and purification of 3'-phosphoadenylyl sulfate labeled with radioactive sulfur. The proposed procedure includes incubation of mouse mast cell tumor (Furth) high-speed supernatant as a source of sulfate-activating enzymes with ATP and sulfate-<SUP>35</SUP>S in the presence of an ATP-generating system and other cofactors. Experimental conditions were established for maximal production of the active sulfate. The radioactive 3'-phosphoadenylyl sulfate synthesized was isolated by ion-exchange column chromatography on ECTEOLA formate. The ammonium bicarbonate used as eluent was removed by lyophilization

The white IRIS leukocyte differential analyzer for rapid high-precision differentials based on images of cytoprobe-reacted cells

Abstract Combining unique cytoprobe, rapid hemacyte fractionation, and novel color image analysis, The White IRIS (TWI) extends automated intelligent microscopy to leukocyte differentiation. TWI provides flow cytometry precision and microscopical resolution to review specimens flagged by hematology analyzers with differential capabilities or to complement other analyzers without these capabilities. The system includes compartments for closed sampling, rapid leukocyte-rich plasma preparation, cytoprobe-induced metachromasia, and collection and color analysis of leukocyte images, and presents the results as a single-view 500-cell differential on a 20-in. (50-cm) touch-screen monitor. Method correlations for the five mature cell types averaging r &amp;gt; 0.90 were obtained with a prototype system. Classification of normal and abnormal specimens showed 95% agreement with a reference method without any undetected significant morphologic abnormality. False-positive and false-negative rates of 7.27% and 3.53%, respectively, exceeded performance of current commercial systems. Case studies demonstrate the ease and speed with which unusual pathologies and leukemias can be observed and interpreted.</jats:p
