The Multi Unit Activity analyzer: a Windows based hardware-software system for low cost, high speed analog to digital data conversion, data acquisition and window discrimination.

The Multi Unit Activity analyzer is a hardware-software package for multi-purpose, two-channel data acquisition, with a computer dependent maximal digitizing frequency selectable from 1 to 27,000 s(-1) on both channels simultaneously. The hardware is connected to an IBM compatible PC through one of the serial ports (standard RS 232 interface). Software was developed to view digitized signals and record or read them on or from the harddisk. The program can also perform amplitude based window discrimination on the raw signal, on-line or during replay. The system is used for recording and analyzing multi unit activity from neuronal tissue in our electrophysiology lab but it can be applied in a variety of other settings. Basic programming routines are available that allow customized data acquisition.

Zygomycosis in HIV-positive patients: a review of the literature.

The literature on zygomycotic infection in HIV-positive patients is reviewed. A total of 28 patients have been reported. The risk factor for HIV infection was known in 22 of these and was sexual transmission in only six patients and intravenous (i.v.) drug use in 16 (73%). In the latter group, it is likely that i.v. drug injection was the entry route of the zygomycotic infection. The most prevalent clinical presentations of zygomycosis in the i.v. drug-using HIV-positive patients were cerebral, cutaneoarticular and renal (accounting for 88% of presentations in total). These presentations were much less common (18%) in a cohort of 116 patients belonging to the conventional risk groups for zygomycosis (HIV negative and no i.v. drug use). The isolated cerebral localization is the typical presentation of zygomycosis in HIV-negative i.v. drug users.
