Yeoman, M. S., B. L. Brezden, and P. R. Benjamin. LVA and HVA Ca currents in ventricular muscle cells of the Lymnaea heart. J. Neurophysiol. 82: 2428–2440, 1999. The single-electrode voltageclamp technique was used to characterize voltage-gated Ca currents in dissociated Lymnaea heart ventricular cells. In the presence of 30 mM tetraethylammonium (TEA), two distinct Ca currents could be identif...

BACKGROUND Optimum duration of dual antiplatelet treatment (DAPT) after coronary stenting remains uncertain, with an unknown efficacy to safety ratio of extended treatment leading to discrepancies between international guidelines and clinical practice. We assessed whether DAPT continuation beyond 1 year after coronary stenting is beneficial. METHODS This analysis was a planned extension of th...

Ronald Rivest, Adi Shamir und Leonard Adleman gelang im Jahre 1977 am MIT die Konstruktion des ersten (praktisch einsetzbaren) asymmetrischen kryptographischen Verfahrens [RiSA_78], das den von Whitfield Diffie und Martin Hellman in ihrem wegweisenden Veröffentlichung „New Directions in Cryptography“ geforderten Eigenschaften genügte [DiHe_76]. Dieses nach den Anfangsbuchstaben der Namen der Au...

2440 When a two-year-old child learns that a short vertical line can represent the number one, and that the number one represents a single item—whatever that item is—he or she has taken a great stride in the development of symbolic thinking. Although many animals can judge numerosity (for example, which of two groups of animals is larger) and can use such judgements for important decisions, suc...

A new method for the vitrification of pure liquid water anddilute aqueous solutions is described which works as the only one without liquidcryomedium for heat transfer : rapid rooling of aqueous aerosol droplets on a solidcryoplate (1). The method can be applied in diverse fields such as cryobiology,crymicrosco~and low temperature spectroscopy of water and aqueous solutions ...

BACKGROUND Ginger (Zingiber officinale Roscoe) is a common condiment for various foods and beverages and widely used worldwide as a spice. Its extracts are used extensively in the food, beverage, and confectionary industries in the production of products such as marmalade, pickles, chutney, ginger beer, ginger wine, liquors, biscuits, and other bakery products. In Ethiopia, it is among the impo...

BACKGROUND Inhalation of cotton-based particulate has been associated with respiratory symptoms and overt lung disease related to endotoxin exposure in some studies. This cross-sectional study measures personal exposure to inhalable dust and endotoxin in the textile industry of Nepal. METHODS This study was conducted in four sectors (garment making, carpet making, weaving, and recycling) of t...

A historical perspective on the study of asymmetries in planetary nebulae (PNs) is presented. We also describe our ongoing work in high resolution spectroscopy of planetaries, and discuss some likely future directions for the study of asymmetrical PNs. The first systematic study of planetary nebulae (PNs) was undertaken at Lick Observatory from 1914 to 1917 and is reported in detail in Volume 1...

BACKGROUND The geographic proximity of parents and adult children is a key element of intergenerational solidarity. Many studies have identified geographical distance as an important determinant of intergenerational support: living nearby increases the amount of mutual support provided. It can, however, also be regarded as a dimension of intergenerational solidarity: the current degree of proxi...

We present an investigation of new optical and ultraviolet spectra of the mass donor star in the massive X-ray binary LS 5039. The optical band spectral line strengths indicate that the atmosphere is N-rich and C-poor, and we classify the stellar spectrum as type ON6.5 V((f)). The N-strong and C-weak pattern is also found in the stellar wind P Cygni lines of N V λ1240 and C IV λ1550 (narrow abs...
