Abstract:
A method of detecting nitric oxide in a sample utilizing electron paragmagnetic resonance spectroscopy and a spin-labeled material such as fusinite to detect changes in the linewidth of the electron paramagnetic resonance signal of the spin-labeled material in the presence of nitric oxide which can be correlated to the quantity of nitric oxide in the sample.
Abstract:
A sensitive, compact detector measures total reactive nitrogen (NOy), as well as NO 2 , NO, and O 3 . In all channels, NO 2 is directly detected by laser diode based cavity ring-down spectroscopy (CRDS) at 405 nm. Ambient O 3 is converted to NO 2 in excess NO for the O 3 measurement channel. Likewise, ambient NO is converted to NO 2 in excess O 3 . Ambient NO y is thermally dissociated at 700C to form NO 2 or NO in a heated quartz inlet. Any NO present in ambient air or formed from thermal dissociation of other reactive nitrogen compounds is converted to NO 2 in excess O 3 after the thermal converter. The precision and accuracy of this instrument make it a versatile alternative to standard chemiluminescence-based NO y instruments.
Abstract:
Methods for inducing an immune response to a tumor in a subject are disclosed herein. These methods include selecting a subject with a tumor and administering a therapeutically effective amount of apopototic tumor cells conjugated to a CpG oligodexoynucleotide (ODN) to the subject. In some embodiments, the CpG ODN is a K-type or a D-type CpG ODN. Methods for treating a tumor in a subject are also disclosed herein. These methods include selecting a subject with a tumor and administering a therapeutically effective amount of apopototic tumor cells conjugated to a CpG oligodexoynucleotide (ODN) to the subject. In some embodiments, the tumor cells are autologous. In additional embodiments, the tumor is a lymphoma, cervical cancer, prostate cancer, breast cancer, colon cancer or a lung cancer.
Abstract:
The invention provides a probe and a method of obtaining a three-dimensional compositional map of one or more targets in a biological sample, or a portion thereof, comprising: (a) milling a surface layer of a biological sample with a focused ion beam, thereby creating a newly exposed surface layer of the biological sample; (b) imaging the newly exposed surface layer of the biological sample; (c) identifying the chemical composition of the newly exposed surface layer of the biological sample, or a portion thereof, with a mass spectrometer; and (d) repeating (a) to (c) until a three-dimensional compositional map of one or more targets in the biological sample, or portion thereof, is obtained. Uses of the three-dimensional map obtained from the inventive method are further provided.

Methods of inhibiting proliferation of a diseased cell, treating or preventing cancer, treating a neoplasm or psoriasis, and inhibiting the expression of genes involved in the Hedgehog signaling pathway, thereby inhibiting the Hedgehog signaling pathway, are furthermore provided by the invention.
Abstract:
Disclosed are methods for determining risk of a therapeutic treatment regimen and for providing a safe therapeutic treatment regimen comprising calculating a total drug burden index of an elderly patient taking at least one medication, e.g., using the equation: TDB = B AC + B s wherein TDB is the total drug burden index, B AC is a drug burden associated with anticholinergic medications, and Bs is a drug burden associated with sedative medications, wherein B AC and B s are each a sum of the expression, D/(δ + D), for every anticholinergic or sedative medication to which the patient is exposed, wherein D is the daily dose of the medication and δ is the recommended minimum daily dose. The invention also provides related systems and computer readable media.
