B1 cells differ in many ways from conventional B cells, most prominently in the production of natural immunoglobulin, which is vitally important for protection against pathogens. B1 cells have also been implicated in the pathogenesis of autoimmune dyscrasias and malignant diseases. It has been impossible to accurately study B1 cells during health and illness because the nature of human B1 cells...

in this research effectiveness of immersing three types of contaminated pistachios fresh with hull (exocarp or epicarp), dried in shell and dried with hull from ohady cultivar in ozonated water 0 ppm (control), 4 and 8 ppm ozone concentrations in aqueous solution for range of exposure times 0(control), 2, 4, 6, 8, 10 and12 hours, to decrease of aflatoxin (b1, b2, g1, g2 and total) were investig...

(-)-Ceralure B1 (ethyl-cis-5-iodo-trans-2-methylcyclohexane-1-carboxylate), a male attractant for the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is significantly more attractive than trimedlure (tert-butyl esters of 4(5)-chloro-2-methylcyclohexane-1-carboxylate), the current standard male attractant used in detection programs. This article reports studies that compare the effectiv...

Abstract Cryopreservation and more specifically oocyte vitrification has become a before after in the field of Assisted Reproduction Techniques. Despite great efforts to improve slow freezing protocols, levels reproducibility, survival rates clinical outcomes achieved by have never been reached any these old approaches. However, once this barrier was overcome, new challenges emerged. We must re...

Leakage of plasma proteins into the alveoli inhibits pulmonary surfactant function and worsens respiratory failure. Surfactant protein B (SP-B), is essential for surfactant function, but the N-terminal domain of human SP-B (residues 1.25, SP-B1-25) can mimic the biophysical properties of full length SP-B1-78 in vitro. The authors compared the function and inhibition resistance of synthetic surf...

Introduction: B1 mapping has a variety of applications including the design of RF pulses in parallel transmit systems, and flip angle calibration for T1 mapping. Many existing B1 mapping methods suffer from T1 dependence, long scan time or inability to handle the large B1 inhomogeneity that occurs even across the human brain at 7T. The Bloch-Siegert B1 mapping method has been recently introduce...

Introduction: B1 mapping is important in a variety of new MR applications, including the design of RF pulses in parallel transmit systems and flip angle calibration for T1 mapping. The Bloch-Siegert (BS) B1 mapping method has been recently introduced as a fast, accurate and robust technique for B1 mapping [1]. In order to compare the quality of B1 maps acquired with the BS method to other metho...

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...
