The CA2 region of the mammalian hippocampus is a unique region with its own distinctive properties, inputs and pathologies. Disruption of inhibitory circuits in this region appears to be linked with the pathology of specific psychiatric disorders, promoting interest in its local circuitry, its role in hippocampal function and its dysfunction in disease. In previous studies, CA2 interneurons, in...
Determining the strata and surface movement of deep mining can provide a scientific basis for wellbore protection mine land utilization. In this paper, numerical simulation methods were employed to investigate stratum boundary curves caving backfilling mining. The findings be concluded in three aspects. First, boundaries all curved conformed an exponential function, but influence range differen...
The kinetics of ethanol transport from the blood to the skin surface are incompletely understood. We present a mathematical model to predict the transient exchange of ethanol across the skin while it is being absorbed from the gut and eliminated from the body. The model simulates the behavior of a commercial device that is used to estimate the blood alcohol concentration (BAC). During the elimi...
OBJECTIVE To identify areas at risk of dengue transmission by means of cluster analysis. METHODS A cluster analysis in which the primary analysis units were the 48 districts of the municipality of Niterói, Southeastern Brazil, was conducted. The districts were grouped into six strata according to sociodemographic conditions, using the k-means cluster analysis method. After defining the strata...
Stratum, the de-facto mining communication protocol used by blockchain based cryptocurrency systems, enables miners to reliably and efficiently fetch jobs from mining pool servers. In this paper we exploit Stratum’s lack of encryption to develop passive and active attacks on Bitcoin’s mining protocol, with important implications on the privacy, security and even safety of mining equipment owner...
Abdominal frog skin, mounted on an Ussing chamber, actively transports sodium from the outer or pond side of the epithelium to the serosal side. The outermost layer of the skin is composed of cornified cells and does not participate in active transport. Pondside sodium enters through the first living layer of cells, the stratum granulosum. Electron microprobe studies demonstrated that the strat...
Methods The HIV surveillance data needed are the number of previously undiagnosed people presenting with AIDS (simultaneous HIV/AIDS) in a year, with their CD4 count. The number of people with a simultaneous HIV/AIDS diagnosis in a given CD4 count stratum represents a proportion of the total undiagnosed population with CD4 count in that stratum. This proportion is equivalent to the annual incid...
BACKGROUND AIDS Clinical Trials Group A5202 compared blinded abacavir/lamivudine (ABC/3TC) to tenofovir DF/emtricitabine (TDF/FTC) with efavirenz (EFV) or atazanavir/ritonavir (ATV/r) in human immunodeficiency virus (HIV)-infected treatment-naive patients, stratified by screening HIV RNA (< or ≥ 10(5) copies/mL). Due to higher virologic failure with ABC/3TC in the high HIV RNA stratum, blinded ...
To determine the usefulness of the cold pressor test as a predictor of hypertension, we compared the blood pressure recordings available from 142 patients in 1979 with readings obtained during performance of two cold pressor tests, the first in 1934 when these subjects were children, and the second in 1961. Forty-eight subjects were hyperreactors to the tests in either 1934 or 1961, and 94 were...
