A simple and rapid procedure to make yeast cells permeable by agitating with toluene-ethanol, (TE) 1:4, v/v was developed. The permeated cells retained their ability to catalyze certain enzyme reactions. Temperature and duration of agitation during TE treatment played an important role in retention of the catalytic potential of permeated cells. The in situ(More)
A 0.18-mum CMOS tri-band MIMO transceiver for fixed and mobile WiMAX applications is presented. The transceiver supports operation in the 2.3-2.7 GHz, 3.3-3.8 GHz, or 4.9-5.95 GHz bands. A novel DC-offset removal scheme is used to enable a low-cost direct-conversion architecture. The transmitter exhibits an EVM of -38 dB, -36 dB, and -33 dB @ 0 dBm output(More)
In this article, we report the spontaneous dissolution of a long cotton thread in the laser in situ keratomileusis (LASIK) flap interface. In this observational case report, sequential follow-up of a post-LASIK eye with a long cotton fiber noticed in the LASIK interface was performed. The postoperative course was uneventful, with no evidence of infection,(More)
