  • Patent number: 11275032
    Abstract: A method of determining the proportion of cyanide in a sample, comprising the following steps: (i) Add the sample to be analysed to a sensor molecule that is selected from cobryrinic acid hepta C1-4 alkyl esters of the Formula I in which X is CN, R3 is H, and R1 and R2 are OCH3; (ii) Subject the sample to UV-vis spectroscopic analysis in the range 450-700 nm; (iii) Determine the free cyanide concentration from the equation (i) C=(A?0.058)/0.104??(i) in which C is the free cyanide concentration and A is A=A581/A527 the ratio of the absorbances at 581 and 527 nm, the equation (i) having been derived from a calibration curve that is a plot of A ratios calculated at 0-1 mg/L CN? with a constant 46 nmol of sensor compound. The method provides a particularly accurate assessment of cyanide concentration in an unknown sample.

  • Patent number: 10952975
    Abstract: Resistance of randomly dispersed and oxygen-starved lung tumor cells to chemo- and radiotherapy constitutes the vast majority recurrences and death from lung cancer. We use sickle cells derived from humans with sickle cell anemia to target oxygen-deprived tumor cells that persist and multiply after conventional treatment. Transfused sickle cells selectively occluded tumor microvessels and shut down blood flow to these oxygen-deprived pockets leading to tumor cell death and complete shrinkage of aggressive lung tumors. Combining the sickle cells with a vascular disrupting agents and radiation injure and narrow tumor blood vessels, amplified the scale of sickle cell-induced blood vessel closure and tumor cell killing. The strength of the tumor killing produced by this combination exceeded that of either agent alone or combined with conventional anti-angiogenics, chemotherapy or radiation.

  • Patent number: 10502666
    Abstract: Among other things, a diluted sample is generated based on mixing a small sample of blood with a one or more diluents. A thin film of the diluted sample is formed on the surface of a contact optical microscopy sensor. Red blood cells within a portion of the thin film of the diluted sample are illuminated using light of a predetermined wavelength. One or more images of the diluted sample are acquired based on illuminating the red blood cells within the portion of the thin film of the diluted sample. The acquired one or more images of the diluted sample are then processed. The mean corpuscular hemoglobin in the red blood cells within the portion of the thin film of the diluted sample is determined based on processing the acquired images of the diluted sample.
