The robustness of the large mixing angle (LMA) oscillation (OSC) interpretation of the solar neutrino data is considered in a more general framework where nonstandard neutrino interactions (NSI) are present. Such interactions may be regarded as a generic feature of models of neutrino mass. The 766.3 ton-yr data sample of the KamLAND collaboration are included in the analysis, paying attention t...

OBJECTIVES The aim of the study was to investigate changes in virological characteristics of HIV strains isolated from 38 HIV-seropositive subjects during antiretroviral therapy. DESIGN AND METHODS Patients with a CD4+ cell count < or = 300 x 10(6)/l were treated with zidovudine (12 individuals) and saquinavir (10 individuals) alone or in combination (16 individuals). CD4+ cell count, viral l...

A number of human immunodeficiency virus type 1 (HIV-1) non-B-subtype products have been developed for present or future vaccine trials; in Thailand, several studies using subtype B and/or CRF01_AE vaccines have been conducted. To better characterize the biologic properties of these subtypes, 70 HIV-1 subtype B and E isolates were phenotyped as syncytium-inducing (SI) or non-syncytium-inducing ...

We present ultrafast optical switching experiments on three-dimensional photonic band gap crystals. Switching the Si inverse opal is achieved by optically exciting free carriers by a two-photon process. We probe reflectivity in the frequency range of second order Bragg diffraction where the photonic band gap is predicted. We find good experimental switching conditions for free-carrier plasma fr...

Figure 2: 3D-computed tomography (CT) scan showing right rotatory atlanto-axial subluxation without any increase in the atlanto-dental distance confirming the diagnosis of Fielding’s type-I atlantoaxial rotatory subluxation. smaller centers. This leads to undue concentration of neurosurgeons in a few centers, where facilities are available, leading to less and less of neurosurgical work for ind...

There are two types of hyaluronidase inhibitor in noimal human serum; one is destroyed when the serum is heated at 55 C to 60 C for 15 to 30 min, the other is not (Thompson and Moses, 1949). The heat-labile inhibitor, referred to as the nonspecific inhibitor (NSI), is present in the serum of many different species and inhibits testicular and several bacterial hyaluronidases (Haas, 1946). The re...

BACKGROUND Nurses are at risk of percutaneous exposure incidents (PEIs), which may lead to serious or even fatal blood-borne infections. OBJECTIVES To determine the prevalence of PEIs in the last year, among nurses and to assess their knowledge about and frequency of safe method of practice in exposure to blood-borne pathogens (especially, to HBV). MATERIALS AND METHODS A cross-sectional st...
