CONTEXT Enterovirus (EV) infection, the most common cause of aseptic meningitis, can be rapidly diagnosed with an EV-specific reverse transcriptase polymerase chain reaction (EV-PCR) test. However, no studies have examined EV-PCR in a clinical context in which it is routinely used. OBJECTIVE To determine the impact of EV-PCR testing on diagnosis and clinical management of suspected aseptic me...

Allowed regions on the ml cos 2θ12 plane are extracted from results of neutrinoless double beta decay experiments. It is shown that 0.05 eV(0 eV)< ∼ml < ∼ 1.85 eV is obtained for the normal (inverted) hierarchy by using the LMA best fit parameters and the 0νββ result announced late last year, which is 0.05 eV ≤ 〈m〉ββ ≤ 0.84 eV with ±50 % uncertainty of the nuclear matrix elements.

A tuneable repetition rate extreme ultraviolet source (Harmonium) for time resolved photoelectron spectroscopy of liquids is presented. High harmonic generation produces 30-110 eV photons, with fluxes ranging from ∼2 × 10(11) photons/s at 36 eV to ∼2 × 10(8) photons/s at 100 eV. Four different gratings in a time-preserving grating monochromator provide either high energy resolution (0.2 eV) or ...

The CF and CF3 1 fragment ion yield curves from C2F4 have been remeasured by photoionization mass spectrometry. Fits with appropriate model curves yield the appearance potentials AP0~CF3 /C2F4!513.72160.005 eV and AP0~CF /C2F4!513.77760.005 eV and an accurate difference in ionization potentials, IP~CF!2IP~CF3!50.05560.003 eV. With the existing photoelectron value IP~CF!59.1160.01 eV, this produ...

At very high energies, the Landau-Pomeranchuk-Migdal effect reduces the cross sections for electron bremsstrahlung and photon e + e − pair production. The fractional electron energy loss and pair production cross sections drop as the energy increases. In contrast, the cross sections for photonuclear interactions grow with energy. In solids and liquids, at energies above 10 20 eV, photonuclear r...

introduction: polycystic ovary syndrome (pcos) is one of the most common endocrinological pathologies in women during their reproductive years with ovulatory dysfunction, abdominal obesity, hyperandrogenism and insulin resistance. the aim of the present research was to evaluate the total antioxidant capacity (tac), total oxidant status (tos), free testosterone, ovarian morphology and estrous cy...

background: viruses are by far the most common cause of meningitis in children. objectives: the aim of this study is to describe the epidemiology of viral/aseptic meningitis (am) in children (2 months - 15 years) in shiraz. materials and methods: this is a cross-sectional prospective-descriptive study from may 2001 to may 2002 in nemazi and dastgheib hospitals, shiraz. ev meningitis was diagnos...
