Abstract: Provided herein are pharmaceutically acceptable compositions containing macrolide antibiotics, in particular azithromycin. In particular, compositions containing azithromycin with low toxicity, especially for administration to felines, are provided herein.

Abstract: This disclosure provides a method for programming human somatic cells into hematopoietic stem cells (HSCs). The method includes inducing expression of the 3GF reprogramming transcription factor cocktail, including GATA2, GFI1B, GFI1, and FOS transcription factors, in human somatic cells. Further, this disclosure also demonstrates co-culturing HSCs with AFT024 stroma cells results in more functional cells, both qualitatively and quantitatively.

Abstract: A method for programming an electronic pipetter to provide more precise measurement and dispensing is provided, as well as an improved display for displaying clearly and in detail the programming steps and options to the user thereof. The electronic pipetter may be operated in one of five modes, including a manual mode, a quick-shot mode, a multi-dispense mode, a sequential-dispense mode and a hands-free mode.

Abstract: A direct reading voltmeter for measuring the output voltage of the final unit of a cascade connected transformer arrangement. A voltage responsive to the output voltage of the final unit of the cascade arrangement is developed across an impedance via a current which is a summation of first and second currents responsive to the current flowing in the first unit, and the voltage applied to the first unit, respectively.

Abstract: Apparatus for measuring the DC resistance of large inductors. A series resistance is connected in series with the inductor and the combination is connected in parallel with a capacitor and a variable resistance. A DC potential is applied to the parallel network to produce a voltage drop across the series resistance, the variable resistance, and the inductor. These voltages are applied to a processing circuit which subtracts the variable resistance voltage from the inductor voltage and divides the difference voltage by the series resistance voltage. The resulting voltage is proportional to the internal resistance of the inductor and does not vary with time when the variable resistance is adjusted to make the time constant of the inductive branch equal to the time constant of the capacitive branch of the parallel network. A differentiation circuit is used to indicate when the variable resistance is set at the proper value to balance the time constants.
