background: two main muscles studied in the hand for evaluation of median nerve injuries are opponens pollicis (op) and abductor pollicis brevis (apb). however, riché-cannieu communicating branch (rccb) may limit the use of these muscles in electrodiagnosis. this condition is confusing in the case of median nerve injuries. this study was conducted to evaluate the prevalence of rccb.   methods: ...

CONTEXT Organophosphate (OP) pesticides are neurotoxic at high doses. Few studies have examined whether chronic exposure at lower levels could adversely affect children's cognitive development. OBJECTIVE We examined associations between prenatal and postnatal exposure to OP pesticides and cognitive abilities in school-age children. METHODS We conducted a birth cohort study (Center for the H...

The detrimental effects of organophosphate pesticide (OP) exposure on neurodevelopment have been shown in animals. The present study aimed to assess the relationship between in utero and early postnatal OP exposure and neonatal neurobehavior in humans, as measured by seven clusters (habituation, orientation, motor performance, range of state, regulation of state, autonomic stability, and reflex...

This paper proposes a procedure to compute abstractions of Discrete Event System (DES) models with the observer property (OP). The procedure, named OP-Search, is based on the OP-Verifier algorithm which verifies if a given natural projection has the observer property. In case OP fails for a projection in Σr of an automatonM , OP-Search modifiesM by relabelling transitions and incorporating the ...

We measured two diethyl organophosphorus (OP) pesticides--chlorpyrifos and parathion--in residences, and their metabolic by-products, in the urine of children 6 years old or younger in a central Washington State agricultural community. Exposures to two dimethyl OP pesticides (azinphos-methyl and phosmet) in this same population have been reported previously. We categorized children by parental ...

This project was primarily funded by a contract with the Department of Pesticide Regulation (DPR) of the California Environmental Protection Agency. The contract was supported by an allotment dedicated to the pesticide monitoring priorities of the California Regional Water Quality Control Boards. The statements and conclusions in this report are those of the contractor and not necessarily those...

The transimpedance or current feedback operational amplifier (CFB op-amp) is reviewed and compared to a conventional voltage mode op-amp using an analysis emphasizing the basic feedback characteristics of the circuit. With this approach the paradox of the constant bandwidth obtained from CFB op-amps is explained. It is demonstrated in a simple manner that the constant gain-bandwidth product of ...

Background: Long-term treatment of rheumatoid arthritis (RA) with prednisolone (PRED) is associated with bone mineral density (BMD) loss. This study aimed to determine the status of BMD in non-compliant women who used PRED alone for RA. Methods: Non-adherent RA taking < 7.5 mg daily PRED without DMARDs for > 6 months, and RA patients taking methotrexate +PRED (RA control) were compared with ag...
