Using computed thermography continuous temperature recordings were made before and after cold challenge of the fingers of control subjects and patients with primary Raynaud's phenomenon and Raynaud's phenomenon associated with systemic sclerosis. Basal skin temperature measurements (Tpre) were significantly lower in patients with primary Raynaud's phenomenon and Raynaud's phenomenon associated ...

It is known that singlet oxygen ((1)O(2)) is the main factor mediating cytotoxicity in photodynamic therapy (PDT). The effectiveness of a PDT treatment is directly linked to the (1)O(2) produced in the target. Although the luminescence from (1)O(2) is suggested as an indicator for evaluating photodynamic therapy, the inherent disadvantages limit its potential for in vivo applications. We have p...

The applicability of a new technique, Microwave-Accelerated Surface Plasmon-Coupled Luminescence (MA-SPCL) for fast and sensitive bioassays in buffer, serum and whole blood using quantum dots as luminescence reporters is demonstrated. In this regard, a model bioassay based on the well-known interactions of biotin and streptavidin is used. Using MA-SPCL, the bioassay was kinetically completed wi...

In a previous study of the photographic venous tracings taken from clinical cases of fibrillation, 1 it was shown that the types of waves occurring during systole could be satisfactorily harmonized with and explained by photographic tracings previously obtained from animal experiments. The diastolic waves, however, could be given several different interpretations. This phase of the subject was,...

Field spectroscopy has undergone a remarkable growth over the past two decades in terms of use and application to different scientific disciplines. This work presents an important step forward to improve the interoperability for the spectral library interchange in the field spectroscopy scientific community, by establishing an XML-based metadata system using published International Organization...

Cryogenic Germanium detectors are widely used in high energy physics and astrophysics – for example in direct dark matter searches (such as the Cryogenic Dark Matter Search experiment), or in neutrino-less double-beta decay experiments (such as MAJORANA). Potential future applications include X-ray observations and measurements of coherent neutrino scattering. In all of these fields, increasing...

Vapochromic complexes [Au(im(CH(2)py)(2))(2)(Cu(MeCN)(2))(2)](3+) 1, [Au(im(CH(2)py)(2))(2)(Cu(MeOH))(2)](3+) 2 and [Au(im(CH(2)py)(2))(2)(Cu(H(2)O))(2)](3+) 3 were theoretically investigated. The Au–Cu distances of 1 and 2 (4.631 Å and 2.767 Å, respectively) optimized by the SCS-MP2 method in this work agree with the literature experimental values (4.591 Å and 2.792 Å). Their structural featur...

If simple arbitrary modes of the form $ are used as coordmates in a win2 flutter cakdation, the equations are ill-conditioned and wm.mt be solvea satisfactorily on a simulator. This ill-conditioning can be avoided by trxmsfoming the flutter matrix so as to m&me the inertw couplings between like modes to zero. This tran.%%mation is &scribed with nmm.uxiL examples, aad some observo.t~ons are nxdo...

The structure and composition of bacterial communities can compromise antibiotic efficacy. For example, the secretion of β-lactamase by individual bacteria provides passive resistance for all residents within a polymicrobial environment. Here, we uncover that collective resistance can also develop via intracellular antibiotic deactivation. Real-time luminescence measurements and single-cell ana...

Multiple assays are available to measure P450 activity in insects, including mosquitoes; however, each of these assays has drawbacks in terms of the number of mosquitoes required, specificity, sensitivity, cost, and/or time required to prepare active enzyme homogenates. In this study, a commercially available luminescent assay, P450-Glo, was modified and evaluated to measure P450 activity from ...
