In the United States, swine salmonellosis is most often attributed to infections by Salmonellaserovar choleraesuis. As a host-adapted pathogen rarely found in nonswine sources, S. choleraesuis is thoughtto be spread primarily via horizontal transmission, with carrier animals playing an important role. Little hasbeen reported regarding infection of neonatal piglets, particularly rega...

BACKGROUND Naval Air Warfare Center Aircraft Division investigated the abilities of small-stature females (< or = 120 lb) to fly under G-stress using the Dynamic Flight Simulator (DFS) and its tactical fight/attack cockpit, displays and controls. OBJECTIVES Determine ability to exert NACES ejection seat actuation pull force under static, acceleration and simulated flight conditions; support u...

An obligatory heterofermentative lactic acid bacterium, Lactobacillus wasatchii sp. nov., isolated from gassy Cheddar cheese was studied for growth, gas formation, salt tolerance, and survival against pasteurization treatments at 63°C and 72°C. Initially, Lb. wasatchii was thought to use only ribose as a sugar source and we were interested in whether it could also utilize galactose. We conducte...

The metal allergens mercuric chloride and nickel sulfate were found to stimulate DNA synthesis of different in vitro cultured lymphoid cells from newborn guinea pigs. In contrast to earlier findings in adult animals (where spleen cells were most consistently stimulated), in newborn animals thymocytes were the most clearly stimulated lymphoid cells. When separating thymocytes by peanut agglutini...

Abstract Optical and infrared continuum polarization from the interstellar medium is driven by radiative processes aligning grains with magnetic field. While a quantitative, predictive theory of alignment torques (RATs) exists has been extensively tested, several parameters remain to be fully constrained. In recent paper, Medan &amp; Andersson showed that efficiency (and therefore grain efficie...

Correction to Wu DD, Irwin DM, Zhang YP: Molecular evolution of the keratin associated protein gene family in mammals, role in the evolution of mammalian hair. BMC Evol Biol 2008, 8:241. Correction In the publication of our work [1], in the table two: Amino acid composition of KRTAPs subfamily genes in mammals, the subfamily 30 should be deleted, and the subfamily 34 should be corrected as 30, ...

Abstract. We present the results of the analysis of the BeppoSAX LECS and MECS pointed observation of the E4 galaxy NGC 3923, for which previous X-ray measurements had given a medium X-ray to optical ratio LX/LB. The spectral analysis over (0.5–10) keV reveals that the best representation of the data is the superposition of two thermal components at temperatures of 0.4 keV and 6–8 keV. The tota...

We analyze the execution of a new suite of medium-sized and realistic benchmarks through simulations on ageneral-purpose, register-oriented architecture at the abstract machine and architectural levels to identify the mostcritical characteristics of Prolog for efficient execution. We propose improvements through modest enhancements tothe architecture and to the Warren abstract machi...

In a study aiming to assess bacterial evolution in complex growth media, we evaluated the long-term adaptive response of Escherichia coli MC1000 in Luria-Bertani (LB) medium. Seven parallel populations were founded and followed over 150 days in sequential batch cultures under three different oxygen conditions (defined environments), and 19 evolved forms were isolated. The emergence of forms wit...
