Cucurbit[8]uril (CB[8]) and cucurbit[6]uril (CB[6]) were applied as a high efficiency absorbent to remove reactive yellow X-RG and reactive brilliant red X-3B dyes in aqueous solution. Factors affecting adsorption such as dosage, contact time, temperature, pH value and metal cation were investigated. The adsorption isotherms for X-RG followed the Langmuir and Sips model while for X-3B followed the Freundlich model. Adsorption thermodynamic showed that X-RG and X-3B adsorption onto CB[8] and CB[6] was a spontaneous and enthalpy-driven process...

The flexibility of σ-conjugated silanes presents new opportunities for manipulating charge generation, transport, and non-linear optical properties of materials. Recently we synthesized a series of acceptor-donor-acceptor (ADA) compounds in which a methylated oligosilane core (D) is flanked by electron-deficient cyanovinyl-substituted arenes (A). Based on a detailed characterization of the photophysics of ADA and donor-acceptor (DA) architectures using both steady state and ultrafast spectroscopic measurements we illustrate that asymmetric charge separation occurs directly following light absorption...

Microelectrode recording (MER) is used to confirm electrophysiological signals within intended anatomic targets during deep brain stimulation (DBS) surgery. We describe a novel technique called intraoperative CT-guided extrapolation (iCTE) to predict the intended microelectrode trajectory and, if necessary, make corrections in real-time before dural opening. Prior to dural opening, a guide tube was inserted through the headstage and rested on dura. Intraoperative CT (iCT) was obtained, and a trajectory was extrapolated along the path of the guide tube to target depth using targeting software...

This paper indicates how continental philosophy may contribute to a diagnostics of contemporary life sciences research, as part of a "diagnostics of the present" (envisioned by continental thinkers, from Hegel up to Foucault). First, I describe (as a "practicing" philosopher) various options for an oblique (or symptomatic) reading of emerging scientific discourse, bent on uncovering the basic "philosophemes" of science (i.e. the guiding ideas, the basic conceptions of nature, life and technology at work in contemporary life sciences research practices)...

Pregnancy with Rh isoimmunization is a grave situation. Two women with indirect Coombs test (ICT) positive were managed conservatively with a favorable outcome. Peak systolic velocity (PSV) of middle cerebral artery (MCA) was measured every 2 weeks, and pregnancy continued till the value remained <1.5 mean of median. In one woman, the pregnancy could be prolonged to 37 weeks when delivery was induced and the neonate did not develop hyperbilirubinemia. In the second woman with bad obstetric history, when a highly positive ICT was reported, intravenous immunoglobulin (IVIG) was given in a single dose of 5 g every 2 weeks starting at 27 weeks, for a total of three doses, along with measurement of PSV of MCA...
