Modular Data Acquisition System for Recording Activity and Electrical Stimulation of Brain Tissue Using Dedicated Electronics.

In this paper, we present a modular Data Acquisition (DAQ) system for simultaneous electrical stimulation and recording of brain activity. The DAQ system is designed to work with custom-designed Application Specific Integrated Circuit (ASIC) called Neurostim-3 and a variety of commercially available Multi-Electrode Arrays (MEAs). The system can control simultaneously up to 512 independent bidirectional i.

[Analysis of liver function in patients with Turner syndrome (TS) and in patients with secondary hypogonadism with estrogen and estrogen- progestagens replacement therapy: a preliminary report].

Objectives: Abnormalities of liver function tests were been reported in adults with TS and in patients with oestrogen replacement therapy.

Design: The aim of this study was to evaluate the prevalence of liver disease in patients before or with oestrogen therapy.

Materials: 79 patients, aged 13(2/12) to 60(4/12), for oestrogen replacement therapy: 13--with secondary hypogonadism (group I), 29--with TS (group II), 19--with menopause (group IV) and 18--with TS, aged 2 to 16(11/12), before oestrogen therapy (group III).
