Formation and spectroscopy of a tryptophan radical containing peptide in the gas phase. | A doubly deprotonated tryptophan containing peptide was electrosprayed and isolated in an ion trap. UV excitation on this peptide leads to electron detachment and to the formation of an indolyl radical. The photogenerated radical was fragmented by a second laser. The visible spectrum of the gas-phase neutral tryptophan... | 18,817,390 |
Bilayer in small bicelles revealed by lipid-protein interactions using NMR spectroscopy. | Intermolecular nuclear Overhauser effects (NOEs) between the integral outer membrane protein OmpX from Escherichia coli and small bicelles of dihexanoyl phosphatidylcholine (DHPC) and dimyristoyl phosphatidylcholine (DMPC) give insights into protein-lipid interactions. Intermolecular NOEs between hydrophobic tails of l... | 18,817,394 |
Polymeric PARACEST agents for enhancing MRI contrast sensitivity. | Linear polymers of PARACEST agents were prepared by using classical free radical chain polymerization conditions. The Eu3+-polymers exhibited similar intermediate-to-slow water exchange and CEST characteristics as the Eu3+-monomers. This provided an avenue to lower the detection limit of these imaging agents substantia... | 18,817,395 |
Integrin binding immunoglobulin type filamin domains have variable stability. | Filamin, a large modular protein composed mainly of many immunoglobulin-like domains, is a potent cross-linker of actin filaments. The region containing immunoglobulin type modules 19-21 makes up the binding site for the cytoplasmic tails of the integrin adhesion receptors. Here we investigate the stability of the Ig-l... | 18,817,417 |
Microwave, photo- and thermally responsive PNIPAm-gold nanoparticle microgels. | Microwave-, photo- and thermo-responsive polymer microgels that range in size from 500 to 800 microm and are swollen with water were prepared by a novel microarray technique. We used a liquid-liquid dispersion technique in a system of three immiscible liquids to prepare hybrid PNIPAm- co-AM core-shell capsules loaded w... | 18,817,426 |
Proteomic analysis of oxidative stress-responsive proteins in human pneumocytes: insight into the regulation of DJ-1 expression. | Oxidative injury is believed to play an important role in the pathogenesis of lung diseases such as emphysema and lung cancer. We examined the effects of a classic reactive oxygen species, H 2O 2, on the hydrogen peroxide response proteins (HPRP) in human pneumocytes using comparative two-dimensional gel electrophoresi... | 18,817,430 |
The intrinsic stiffness of polyglutamine peptides. | We have used the method of Trp/Cys contact quenching to measure the rate of contact formation in polyglutamine and find it to be a very stiff peptide. Separation of observed rates into reaction-limited and diffusion-limited rates show that the reaction-limited rates increase (rather than decrease) slightly with length ... | 18,817,433 |
Insights into melanosomes and melanin from some interesting spatial and temporal properties. | Melanosomes are organelles found in a wide variety of tissues throughout the animal kingdom and exhibit a range of different shapes: spheres of up to approximately 1 mum diameters and ellipsoids with lengths of up to approximately 2 mum and varying aspect ratios. The functions of melanosomes include photoprotection, mi... | 18,817,437 |
Shape-controlled platinum nanocubes and their assembly into two-dimensional and three-dimensional superlattices. | Liquid-liquid phase transfer has been used to synthesize platinum nanocrystals with a cubic morphology. By finely tuning the parameters controlling the nucleation and growth processes, nanometric truncated cubes or perfect cubes may be obtained. To our knowledge, this is the first time such shapes are obtained with thi... | 18,817,438 |
Factors governing helix formation in peptides confined to carbon nanotubes. | The effect of confinement on the stability and dynamics of peptides and proteins is relevant in the context of a number of problems in biology and biotechnology. We have examined the stability of different helix-forming sequences upon confinement to a carbon nanotube using Langevin dynamics simulations of a coarse-grai... | 18,817,452 |
A national risk assessment for intersex in fish arising from steroid estrogens. | The occurrence of intersex fish is widespread in the rivers of England and Wales. The extent of intersex in fish populations is believed to be strongly linked to their exposure to steroid estrogens. The present study presents, to our knowledge, the first national, catchment-based risk assessment for steroid estrogens i... | 18,817,457 |
Prospects for life span extension. | Life expectancy has increased dramatically in the United States and in much of the world in recent years and decades. The factors underlying this increase are incompletely understood and are undoubtedly complex. A question that drives current research is whether life expectancy can be further extended using current kno... | 18,817,460 |
Dendrimers for enhanced drug solubilization. | Approximately 40% of newly developed drugs are rejected by the pharmaceutical industry and will never benefit a patient because of low water solubility. Another 17% of launched drugs exhibit suboptimal performance for the same reason. Given the growing impact and need for drug delivery, a thorough understanding of deli... | 18,817,470 |
The muscle stem cell niche: regulation of satellite cells during regeneration. | Satellite cells are considered to be adult skeletal muscle stem cells. Their ability to regenerate large muscle defects is highly dependent on their specific niche. When these cells are cultured in vitro, the loss of this niche leads to a loss of proliferative capacity and defective regeneration when implanted back int... | 18,817,477 |
Cost comparison between telemonitoring and usual care of heart failure: a systematic review. | Heart failure (HF) is associated with high direct and indirect costs to the patients and the healthcare system.
