( fig. 2 ) as well as Sabouraud culture yeast colonies with a brain-shaped appearance that were identified as Trichosporon spp. The affected hairs were examined by dermoscopy that showed fusiform and yellow nodules of Trichosporon spp. around the hair shaft and attached to the distal parts of the hair ( fig. 3 ). The patient was treated with itraconazole 100 mg/day and topical selenium sulfur s...

Although high melamine (MEL) intake has been proven to cause serious health problems, MEL is sometimes illegally added to milk products and animal feed, arousing serious food safety concerns. A satisfactory method of detecting MEL in onsite or in-home testing is in urgent need of development. This work aimed to explore a rapid, convenient, and cost-effective method of identifying MEL in milk pr...

A biofilm-forming strain of sulfate-reducing bacteria (SRB), isolated from a naturally occurring mixed biofilm and identified by 16S rDNA analysis as a strain of Desulfomicrobium norvegicum, rapidly removed 200 micro M selenite from solution during growth on lactate and sulfate. Elemental selenium and elemental sulfur were precipitated outside SRB cells. Precipitation occurred by an abiotic rea...

The physical signi6cance of the 6rst di8'raction peak in glassy Se is discussed in the light of recent experimental results regarding the temperature dependence of the parameters characterizing the first peaks in the elastic S(Q, u = 0) and static S(Q) structure factors. The rather different behavior with temperature of both peaks as well as a comparison with the behavior observed for a polycry...

The experimental curves giving the temperature dependence of the thermal conductivity of glassy selenium are considered in detail. The observed behavior can be taken into account quantitatively if the densities of states for short-wavelength phonons as well as for low-energy librations arising from computer simulations are used for the calculations. In particular, it is shown that the lowestfre...

The phenomenon of negative remanent magnetization (NRM) has been observed experimentally in a number of heterogeneous magnetic systems and has been considered anomalous. The existence of NRM in homogenous magnetic materials is still in debate, mainly due to the lack of compelling support from experimental data and a convincing theoretical explanation for its thermodynamic validation. Here we re...

D iphenyl(l-pyridyl)phosphine sulfide, Ph2pyPS, 1, gives a 1:1 complex (2) with AuCl upon treatm ent with (C4HsS)AuCl. According to an X-ray diffraction analysis, this com ­ pound is isom orphous with the Ph^PS complex. [Ph3PAu]BF4 and 1 give the cationic com plex [Ph;?PAuSPpyPh2]BF4 (3 ) . With two equivalents o f the same reagent the binuclear com plex 4 is generated, in which the metal atoms...

The molecule of the title compound, [ZnBr(2)(C(10)H(8)N(2)S)], contains a six-membered chelate ring in a boat conformation in which the Zn atom is coordinated by two Br atoms and by the two pyridyl N atoms of a single di-2-pyridyl sulfide (dps) ligand within a slightly distorted tetra-hedron. The dihedral angle between the pyridine rings is 52.7 (1)°. As is usual for this type of complex, the s...
