A reduction in gastroenteritis hospitalizations of 26% and 48% in 2006 and in 2007, respectively, was observed among children younger than 1 year compared with prevaccination period (1998-2005). The largest reduction rates among children younger than 1 year were noted in the South and Southeast regions, approximately 56% in 2007, where vaccine coverage was the highest.”
“Structural and magnetic properties of bulk nanostructural Mn(100-x)Bi(x) (x = 40, 45, 52) permanent magnets

prepared by spark plasma sintering technique were studied. The effect of the Mn/Bi ratio on the MnBi low temperature phase (LTP) formation and its magnetic properties were investigated. An increase of CX-6258 the bismuth amount in the magnets leads to better formation of LTP, resulting in the improvement of both magnetization (M(s)) and remanence (M(r)), but decreasing the coercivity see more (H(c)) of the magnets. At room temperature, M(s) increases from 27.87 emu/g for Mn(60)Bi(40) to 45.31 emu/g for Mn(48)Bi(52), whereas H(c) decreases from 12 to 7.9 kOe. The microstructure of Mn(48)Bi(52) magnet is composed of fine and uniform grains with an average size of 140 nm as shown in the TEM image. The Mn(48)Bi(52) magnet shows a high H(c) of 19 kOe at 423 K, indicating a strong positive temperature coefficient of coercivity for

the MnBi magnet. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3561784]“
“Rapidly declining visual acuity from neuroretinitis should prompt aggressive diagnostic intervention to preserve eyesight. We present a young adult with human immunodeficiency virus (HIV) infection in whom

neuroretinitis was the presenting feature of disseminated bartonellosis. Tissue biopsy was required to establish the diagnosis and directed therapy was associated with restored vision.”
“We Fer-1 in vivo theoretically study the propagation of hybrid electromagnetic-spin waves in a multiple-band-stop microwave waveguide, which is constructed as an antiferromagnetic (AFM1)/dielectric/antiferromagnetic (AFM2) sandwiched structure. Band stops, which are characterized by multiple attenuation peaks, have been found in the system. The frequencies of multiple band stops and the intensities of attenuation peaks can be manipulated by external magnetic field. However, by tuning the thickness of the dielectric layer or the thickness of AFM layers, the frequencies of the band stop are almost invariable, while the intensities of the attenuation peaks change significantly. This feature originates from the coupling between the microwave and spin wave associated with the collective excitations of spin motions. Our investigation may potentially be applied to the design of high-frequency microwave band-stop filters. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3535440]“
