In the process, a fresh or frozen sample is stained with DNA-binding fluorescent dye and imaged with a microscope. The brightness of the sperm head is averaged and compared with samples of known fertility.
The gel can contain a combination of therapeutic agents like rapamycin, paclitaxel and 17-AAG. After being administered to a patient, the gel releases the drugs at a controlled rate, and then biodegrades into nontoxic fragments.
Drug-eluting stents and other medical devices containing idarubicin (or an analog) could be administered prior to or following a vascular procedure like angioplasty.
The receiver system includes two antennas and a processing circuit with a differential phase shifter (DPS). The second antenna receives a signal, which then is phase shifted as a function of its angle of incidence relative to the array’s boresight axis. An output signal can be configured by combining the phase-shifted signal with the first antenna’s original signal.
Three distinct DPS methods can achieve the same result. Active DPS can be implemented using a mixer, filters, amplifiers and voltage controlled phase shifter. Direct DPS is another analog process, while digital DPS samples and processes the antenna signals digitally.
Known methods may be used to fabricate the semiconductor structure and laser devices and to form the electron injector, active region and electron extractor. The active region features a series of quantum wells and barriers of various alloy compositions. The energies of the first and second barrier in the active region are less than the third barrier.
Before the protein or small molecule is integrated into the film, a cationic protein transduction domain, such as nonaarginine, is attached to it. Appending short, cationic peptides or oligomers to proteins can facilitate their layer-by-layer assembly into PEMs, as well as their uptake by cells.
Then the cationic molecule is incorporated into a polyelectrolyte multilayered film, along with anionic polymers such as sodium polystyrene sulfonate, to result in a multilayered assembly that is preferably about 80 nanometers thick. When this composition is presented to a cell, the film dissolves, delivering the molecule to the cell.
