We have measured the intrinsic exciton dephasing in high-quality zinc blende CdSe/CdS colloidal quantum dots in the temperature range from 5 to 170 K using a sensitive three-beam photon echo technique in heterodyne detection, which is not affected by spectral diffusion. Pure dephasing via acoustic phonons dominates the initial dynamics, ...

Nanotechnology is a fast growing emerging field, the benefits of which are widely publicized. Our current knowledge of the health effects of metal nanoparticles such as nanosized cobalt (Nano-Co) and titanium dioxide (Nano-TiO(2)) is limited but suggests that metal nanoparticles may exert more adverse pulmonary effects as compared with standard-sized ...

Prions consist of PrP (Sc), a misfolded version of the cellular protein PrP (C). They occur in a variety of strains that share the amino acid sequence of PrP but differ in phenotypic properties, such as cell tropism and pathogenicity; strain-ness is attributed to the conformation of PrP (Sc). To ...

Catalytic enantioselective methods for the preparation of chiral azaarene-containing compounds are of high value. By combining the utility of copper hydride catalysis with the ability of C═N-containing azaarenes to activate adjacent alkenes toward nucleophilic additions, the enantioselective reductive coupling of alkenylazaarenes with ketones has been developed. The process is tolerant ...

In contrast to homotrimeric transporters of the RND (resistance-nodulation-division) superfamily, which often conduct efflux transport of a wide range of substrates by the functionally rotating mechanism, the mechanism utilized by the heterotrimeric members of this family, which also perform multidrug efflux, is unclear. We examined one heterotrimeric transporter, the MdtB(2)C ...

There is an increasing interest in using graphene (1, 2) for optoelectronic applications. (3-19) However, because graphene is an inherently weak optical absorber (only ≈2.3% absorption), novel concepts need to be developed to increase the absorption and take full advantage of its unique optical properties. We demonstrate that by monolithically ...

Cardiovascular effects and pharmacokinetics of nebivolol were assessed in spontaneously hypertensive rats (SHR) and Wistar Kyoto (WKY) animals. Male SH and WKY rats were treated with vehicle or nebivolol 0.3, 3, or 10 mg kg(-1) (i.v.) and effects on blood pressure (BP), heart rate, and blood pressure variability (BPV) were recorded. Plasma ...

Methanogenic archaea are reported as very sensitive to lipids and long chain fatty acids (LCFA). Therefore, in conventional anaerobic processes, methane recovery during LCFA-rich wastewater treatment is usually low. By applying a start-up strategy, based on a sequence of step feeding and reaction cycles, an oleate-rich wastewater was efficiently treated ...

A 42-year old woman was referred for a metabolic evaluation after two episodes of kidney stones. Her laboratory results revealed a normal anion-gap metabolic acidosis, a marked hypocitraturia (0,6 mmol/24h; norm 1,6-4,5) and a urinary pH of 7,0 confirming renal tubular acidosis (RTA). We identified topiramate, our patient's medication for ...

Red-colored bones were first found in Guishan goats in the 1980s, and they were subsequently designated red-boned Guishan goats. However, the difference remains unclear between the bone mineral density (BMD) or elemental composition in bones between red-boned Guishan goats and common Guishan goats. Analysis of femoral bone samples by dual-energy ...

Polo-like kinase 1 (Plk1) is an essential mitotic regulator and undergoes periodic phosphorylation on threonine 210, a conserved residue in the kinase's activation loop. While phosphate-mimicking alterations of T210 stimulate Plk1's kinase activity in vitro, their effects on cell cycle regulation in vivo remain controversial. Using gene targeting, we replaced ...

Osteosarcoma (OS) is known to have several morphological appearances, small cell osteosarcoma and epithelioid osteosarcoma being two well recognized patterns. The former can be mistaken for a Ewing sarcoma/primitive neuroectodermal tumour (ES/PNET), whereas the latter mimics metastatic carcinoma. Herein we present an osteosarcoma in a 17-year-old girl that was diagnosed ...
