Activated ClpP kills persisters and eradicates a chronic biofilm infection
Chronic infections are difficult to treat with antibiotics but are caused primarily by drug-sensitive pathogens. Dormant persister cells that are tolerant to killing by antibiotics are responsible for this app...

Microwave annealing for preparation of crystalline hydroxyapatite thin films
A sol was spun on single crystal silicon substrates at a spin-rate of 3000–5000 rpm followed by a low temperature cure to form a stable sol–gel/silicon structure. Good quality crystalline HA films of thickness...

Mechanisms of action of pH-induced effects on vascular smooth muscle
It is clear that pH has many effects on vascular smooth muscle and the overall action of pH on force will depend on the type of vascular smooth muscle in question and the combined effects on all the potential ...

Membrane Cholesterol Regulates Smooth Muscle Phasic Contraction
The regulation of contractile activity in smooth muscle cells involves rapid discrimination and processing of a multitude of simultaneous signals im**ing on the membrane before an integrated functional respo...

Nanoscale proteomics
Efforts to develop a liquid chromatography (LC)/mass spectrometry (MS) technology for ultra-sensitive proteomics studies (i.e., nanoscale proteomics) are described. The approach combines high-efficiency nanosc...

Breeding Bird Assemblages and Habitat Use of Alpine Areas in Scotland
‘Where a species is adapted to a particular habitat, its distribution limits will tend to be circumscribed by whatever conditions restrict the occurrence of that habitat, but these conditions may vary over the...

The effect of high energy electrons during the growth of ZnSe and ZnMgSe by molecular beam epitaxy
Electron irradiation during reflection high-energy electron diffraction is shown to affect the growth of ZnSe and ZnMgSe by molecular beam epitaxy. The high-energy electrons produce an electron stimulated deso...

The effects of changing intracellular pH on calcium and potassium currents in smooth muscle cells from the guinea-pig ureter
Guinea-pig ureteric smooth muscle is unusual in that intracellular acidification increases and alkalinization decreases force production. To help elucidate the mechanism underlying these effects on force we h...

A Conceptual-Modeling Approach to Extracting Data from the Web
Electronically available data on the Web is exploding at an ever increasing pace. Much of this data is unstructured, which makes searching hard and traditional database querying impossible. Many Web documents,...

Generation of voluminous silicic magmas and formation of mid-Cenozoic crust beneath north-central Mexico: evidence from ignimbrites, associated lavas, deep crustal granulites, and mantle pyroxenites
Isotopic and trace element data from mantle and granulite xenoliths are used to estimate the relative contributions of mantle and crustal components to a large ignimbrite, referred to as the upper ignimbrite,...

Changes of pH affect calcium currents but not outward potassium currents in rat myometrial cells
Spontaneous contraction of uterine smooth muscle is enhanced by alkalinization and depressed by acidification. We have investigated the ionic currents responsible for this in single myometrial cells. Intracell...

Article
Protein-phosphatase inhibitors block root hair growth and alter cortical cell shape of Arabidopsis roots
Emerging evidence suggests that protein phosphatases play an important role in the growth and development of higher plants. We report here on the effects of okadaic acid and calyculin-A, two specific and poten...

Magnetic Susceptibility Studies of the Influences of Thermomechanical Processing and Mn Addition on Phase Stability and Precipitation in NbTi Alloys
The DC magnetic susceptibilities, χ, of series of NbTi and NbTiMn(0.5 at. %) alloys were measured using the Faraday (Curie) balance technique over the temperature range 77–300 K. The samples were measured in t...

CT and MRI scans in thoracic intradural disc herniation
Thoracic intradural disc herniation is rare and difficult to diagnose clinically and radiologically. Axial CT myelography and MRI may show a typical complex intrathecal mass consisting of the spinal cord displ...

Nuclear reactions and screened-coulomb fusion rates
We discuss properties of nuclear reactions (branching ratios, reaction constants, etc.) between hydrogen isotopes from the standpoint of recent R-matrix calculation.. Using R-matrix theory to include nuclear e...
