Electrical impedance spectroscopy (EIS) and cyclic voltammetry (CV) measure properties of the electrode-tissue interface without additional invasive procedures, and can be used to monitor electrode performance over the long term. EIS measures electrical impedance at multiple frequencies, and increases in impedance indicate increased glial scar formation around the device, while cyclic voltamme...

BACKGROUND High concentrations of estrone sulfate (EIS) are present in serum of pre- and postmenopausal women. Most assays for this estrogen conjugate involve enzyme hydrolysis and chromatographic purification prior to RIA. We have compared concentrations of serum EIS in postmenopausal women measured by direct RIA or GC-MS/MS methods. PATIENTS AND METHODS We analysed serum EIS concentrations ...

Introducing enterprise information systems (EIS) is usually associated with high costs. It is therefore crucial to understand those factors that determine or influence these costs. Though software cost estimation has received considerable attention during the last decades, it is difficult to apply existing approaches to EIS. This difficulty particularly stems from the inability of these methods...

Purpose. This study was designed to assess retinal and optic nerve bioelectrical function in patients with unilateral asymptomatic but hemodynamically significant internal carotid artery stenosis (ICAS). Methods. Forty-two subjects with a diagnosis of unilateral ICAS and 34 controls were analyzed. Full-field electroretinogram (ERG), pattern electroretinogram (PERG), and pattern visual-evoked po...

OBJECTIVES Nursing homes (NHs) provide complex care for individuals with comorbidity who rely on multiple medications. Electronic information system (EIS) may reduce errors in drug dispensing and medical administration records (MAR). This paper tests whether the percentage of occupancy and metropolitan location are associated with the likelihood of using EIS for clinical care support. DESIGN/...

OBJECTIVES Kanamycin is an important second-line drug used to treat multidrug-resistant (MDR) tuberculosis (TB). Molecular analysis of the rrs gene seems to be not enough to identify every case of kanamycin resistance. In the present study we evaluated the incidence of eis mutations in kanamycin-resistant Mycobacterium tuberculosis isolates. METHODS We analysed 70 MDR M. tuberculosis clinical...

This paper is based on a panel presentation to the first International Conference on Enterprise Information Systems (EIS). The panel intends to address important issues in EIS from the perspectives of research and industry. It has not only raised questions, concerns and topics related to the research, development and application of information technologies and systems, but also suggested approa...

BACKGROUND Early intervention services (EIS) comprise low-stigma, youth-friendly mental health teams for young people undergoing first-episode psychosis (FEP). Engaging with the family of the young person is central to EIS policy and practice.AimsBy analysing carers' accounts of their daily lives and affective challenges during a relative's FEP against the background of wider research into EIS,...

Breast Cancer is among the top five causes of cancer death and the topmost cause among women worldwide. The early diagnosis through simple, non-invasive and inexpensive screening can provide great deal of aids. Multi-frequency Electrical Impedance Spectroscopy (EIS) is quite attractive in this context as the instrumentation is relatively simple and research has demonstrated application in breas...
