OBJECTIVE To update physicians on Group A streptococcal necrotizing fasciitis, including current methods of diagnosis and treatment. QUALITY OF EVIDENCE Current literature (1990-1998) was searched via MEDLINE using the MeSH headings necrotizing fasciitis, toxic shock syndrome, and Streptococcus. Articles were selected based on clinical relevance and design. Most were case reports, case series...

Fosfomycin is a broad-spectrum antibiotic which is established as therapy for uncomplicated lower urinary tract infections. In addition, preliminary data indicate that fosfomycin has a potential role in the treatment of soft tissue infections. However, the use of fosfomycin has not been established for this condition, and it is unclear whether the level of fosfomycin penetration into human soft...

We study a finite SU(5) grand unified model based on the non-Abelian discrete symmetry A4. This model leads to the democratic structure of the mass matrices for the quarks and leptons. In the soft supersymmetry breaking sector, the scalar trilinear couplings are aligned and the soft scalar masses are degenerate, thus solving the SUSY flavor problem. 12.60.Jv,11.30.Hv,12.10.-g,12.10.Kt,11.10.Hi ...

Polypropylene grafted maleic anhydride (PP-MA, 2500 g mole(-1)) has demonstrated its unique capability to synthesize 1-D ferromagnetic hard (292.7 Oe) γ-Fe2O3 nanochains made of ~24 nm nanoparticles vs. PP-MA with 8000 g mole(-1) for the synthesis of 1-D ferromagnetic soft (70.5 Oe) γ-Fe2O3 nanochains (30 nm) made of flowerlike nanoparticles.

It has been known for many years that soft radiation can give potentially large double-logarithm corrections to $p_\perp$ broadening of a high-energy particle traveling through QCD matter, but this correction be absorbed into an effective value $\hat q_{\rm eff}$ the medium $p_\perp$-broadening parameter q$. Here "soft" means high energy compared scales original medium. A similar situation aris...

The Cheshire cat principle states that hadronic observables at low energy do not distinguish between hard (quark) or soft (meson) constituents. As a result, the delineation between hard/soft (bag radius) is like the Cheshire cat smile in Alice in wonderland. This principle reemerges from current holographic descriptions of chiral baryons whereby the smile appears in the holographic direction. W...
