Abstract: Provided herein is a method for identifying compounds that inhibit cell growth or have cytotoxic activity against cancer cells, such as hematological cancer cells or ovarian cancer cells, in a subject. Further provided is a method for identifying one or more compounds that sensitize refractory cancer cells from a subject. Also provided are compositions and methods for treating cancer, including refractory cancer, such as refractory acute myeloid leukemia (AML) or ovarian cancer.

Abstract: The invention relates to compounds known as “optorelaxers,” for example, spin crossover (SCO) complexes that exhibit light-induced excited state spin trapping (LIESST) effects with transient unpaired electron spins, which are created (or destroyed) by varying the level and/or wavelength of light to which the complexes are exposed. Light conditions are used to switch the optorelaxers between transient paramagnetic and diamagnetic states to provide real-time control of T1 relaxation in nuclear magnetic resonance (NMR) spectroscopy methods. The optorelaxers and methods of the invention provide increased detection sensitivity of NMR spectroscopy, with increased structural information content, while maintaining resolution for a wide variety of different NMR-active nuclei.

Abstract: Provided are embodiments of creatine and creatine ethyl ester (CEE) salts where the anion is an artificial (non-saccharide) taste-modifier. These compounds represent stable white non-hygroscopic solids or semisolids that can readily dissolve in water and buffer solutions. Synthesis of novel creatine salts using environmentally safe solvents such as ethanol resulted in the formation of products in quantitative yields with sodium or potassium chloride as a byproduct. The creatine and creatine alkyl eater derivative salts are stable sweet-tasting compounds that are more palatable to a consumer than creatine or derivatives thereof.

Abstract: Disclosed are methods for regulating the self-renewal capacity of stem cells such as, but not limited to, primitive hematopoietic stem cells (HSCs) (both mouse and human) by modulating the function and/or activity of target factors that are controlled or altered in their regulation by AML1-ETO expression in stem cells such as HSC. Target factors include, but are not limited to, AML1, C/EBP alpha, and/or PU.1 either individually, or in combinations, Altering the function and/or activity of such target factors in HSC leads to inhibition of HSC differentiation and stimulation of HSC self-renewal capacity. Modulation of target factor activity may be achieved at the level of synthesis of these target factors, interaction with cellular factors required for basal activity or enhanced activity, such as cofactors, interactions with their DNA binding motifs, or by targeted degradation or inhibition of their mRNAs.

Abstract: A magnetic resonance detection apparatus is provided that is not susceptible to acoustic ringing, and a method is provided for eliminating or canceling acoustic ringing from a detected magnetic resonance signal. Specifically, a composite pulse is utilized that allows for both efficient reduction of acoustic ringing signals and the detection of true NQR signals. The composite pulse can be used in any of the common NQR pulse sequences currently utilized simply via substitution of the original single pulses with the composite pulse. Furthermore, although a preferred application involves the spin-1 nucleus 14N and NQR, the composite pulse will be useful for the NQR of other nuclei such as 35Cl and 39K and in NMR applications and involving half-integer quadrupolar nuclei and spin-½ nuclei. In addition, coil ringdown and piezoelectric ringing are also substantially reduced.
