Abstract We evaluated the temperature coefficients from 25 to 38 °C for aqueous calibration materials, serum (protein-based) control material, and patients’ samples in blood pH measurements and gas analysis. Whereas the aqueous buffers and calibration gases (used as unknowns) were not affected by changing temperature, the temperature coefficients of patients’ samples and protein-based control materials varied similarly to those reported in the literature: 0.011 and 0.014 vs. 0.015 pH/ °C, and 1.76 and 1.57 vs. 1.80 mm Hg/°C. We conclude that the periodic use of suitable control materials can assist in the detection of temperature abnormalities.

Monitoring Temperature

Photothermal therapy relies on the principle of converting light energy into heat causing localized lesion destruction. For safe and effective treatment, it is necessary to monitor temperature diffusion in the boundaries of the irradiated region, to minimize damage to surrounding normal tissues. This paper gives a pilot study of the feasibility of photoacoustic imaging for monitoring temperature changes during photothermal therapy. The results showed that our system of photoacoustic imaging (PAI) can play the role of biosensor, for the photoacoustics signal amplitude depend on temperature of tissue-mimicking phantoms. Whats more, photoacoustic signal can determinate the boundary of photoabsorder-enhance tissue during therapeutic procedure.

To achieve complete microstructural characterization of self-aggregating systems, one needs direct images in addition to quantitative information from non-imaging, e.g., scattering or Theological measurements, techniques. Cryo-TEM enables us to image fluid microstructures at better than one nanometer resolution, with minimal specimen preparation artifacts. Direct images are used to determine the “building blocks” of the fluid microstructure; these are used to build reliable physical models with which quantitative information from techniques such as small-angle x-ray or neutron scattering can be analyzed.To prepare vitrified specimens of microstructured fluids, we have developed the Controlled Environment Vitrification System (CEVS), that enables us to prepare samples under controlled temperature and humidity conditions, thus minimizing microstructural rearrangement due to volatile evaporation or temperature changes. The CEVS may be used to trigger on-the-grid processes to induce formation of new phases, or to study intermediate, transient structures during change of phase (“time-resolved cryo-TEM”). Recently we have developed a new CEVS, where temperature and humidity are controlled by continuous flow of a mixture of humidified and dry air streams.
