Functional hydrogels show great potential for promoting the structural integration and signal transduction at bio/electronic interfaces.

<p><strong>Background</strong>: Heart disease in pregnancy is one of the leading causes morbidity and mortality childbirth. The intrapartum postpartum periods are critical which most deaths occur this period. Manifestations appear form heart failure increases maternal fetal mortality.</p><p><strong>Case Illustration</strong>: We will report a case 23-ye...

OBJECTIVE The aim of the paper is to offer a comprehensive approach to establishing the validity of allegations of sexual abuse by nonverbal autistic children and adults produced through facilitated communication (FC). This approach is offered as an alternative to existing methodology that relies exclusively on the "message passing" task, and has been used to advantage in the courts. METHOD T...

Multi-shelled Mn2O3 hollow microspheres have been achieved through a pH-regulated method and used as supercapacitor electrodes. The designed unique architecture allows efficient use of pseudo-capacitive Mn2O3 nanomaterials for charge storage with facilitated transport for both ions and electrons, rendering them high specific capacitance, good rate capability, and remarkable cycling performance.

The kinetics of Cu(II) transport through a bulk liquid membrane with different membrane materials was investigated in this work. Three types of membrane materials were used: fresh cooking oil, waste cooking oil and kerosene, each of which was mixed with di-2-ethylhexylphosphoric acid (carrier) and tributylphosphate (modifier). Kinetic models derived from the kinetic laws of two consecutive irre...

A new class of redox-switched anthraquinone derived lariat ethers 1-(1-anthraquinonyloxy) 3, 6, 9 trioxaundecane 11-ol (M(1)), 1-(1-anthraquinonyloxy) 3, 6 dioxaoctane 9-ol (M(2)), 1-(1-anthraquinonyloxy) 3 oxapentane 5-ol (M(3)), 1-(1-anthraquinonyloxy) 3 oxapentane 5-butane (M(4)), 1-(1-anthraquinonyloxy) 3, 6 dioxaoctane 9-methane (M(5)) and 1-(1-anthraquinonyloxy) 3 oxapentane 5-methane (M(...

This paper deals with the facilitated diffusion of oxygen in systems containing proteins, such as ferrohemoglobin, that combine reversibly with oxygen. The phenomenon is treated in terms of translational diffusion of free and bound oxygen molecules, and of the reaction rate of the oxygen molecules with the oxygen-binding protein. These considerations lead to a differential equation (see Equatio...

The mechanism of melibiose symport by the melibiose permease of Escherichia coli was investigated by further analyzing the Na+ (H+ or Li+)-coupled facilitated diffusion reactions catalyzed by the carrier in de-energized membrane vesicles, with particular emphasis on the reaction of sugar exchange at equilibrium. It is first shown that melibiose exchange at equilibrium proceeds without concomita...

Nuclear pore complexes provide the sole gateway for the exchange of material between nucleus and cytoplasm of interphase eukaryotic cells. They support two modes of transport: passive diffusion of ions, metabolites, and intermediate-sized macromolecules and facilitated, receptor-mediated translocation of proteins, RNA, and ribonucleoprotein complexes. It is generally assumed that both modes of ...

BACKGROUND The early steps of human immunodeficiency virus 1 (HIV-1) replication involve reverse transcription of the viral RNA and integration of the resulting cDNA into a host chromosome. The DNA integration step requires the integration machinery ('preintegration complex') to bind to the host DNA before connecting the viral and host DNAs. Here, we present experiments that distinguish among t...
