The Influence of Transcranial Alternating Current Stimulation on Fatigue Resistance.

Previous research has shown that some forms of non-invasive brain stimulation can increase fatigue resistance. The purpose of this study is to determine the influence of transcranial alternating current stimulation (tACS) on the time to task failure (TTF) of a precision grip task. The study utilized a randomized, double-blind, SHAM-controlled, within-subjects design.

Biochemical markers of nephrotic syndrome: An observational, cross-sectional study.

Background: Blood protein leakage, especially albumin, into the urine is the hallmark of nephrotic syndrome (NS), which poses a serious public health problem. The absence of albumin prompts the liver to produce more proteins to make up the difference. The therapeutic significance of these additional proteins in NS is not yet fully understood.

Innovations in Hemodialysis Care: An Evaluation of Quality and the Patient Experience.

Hemodialysis (HD) performed in a tertiary care facility is the most prevalent and costly treatment for end-stage renal disease in Canada. This life-sustaining treatment is usually performed thrice weekly in an in-center facility. When people on HD also require a rehabilitation/complex care inpatient program, the burden of transportation for dialysis is immense to both the patient and health-care system.

Comprehensive Analysis of Metal Modulated Epitaxial GaN.

While metal modulated epitaxy (MME) has been shown useful for hyperdoping, where hole concentrations 40 times higher than other techniques have been demonstrated, and the ability to control phase separation in immiscible III-nitrides, the complexity of the dynamically changing surface conditions during the cyclic growth is poorly understood. While MME is capable of superb crystal quality, performing MME in an improper growth regime can result in defective material. These complications have made the transfer of MME knowledge challenging.

Precision measurement of the neutral pion lifetime.

The explicit breaking of the axial symmetry by quantum fluctuations gives rise to the so-called axial anomaly. This phenomenon is solely responsible for the decay of the neutral pion π into two photons (γγ), leading to its unusually short lifetime. We precisely measured the decay width Γ of the [Formula: see text] process.

New Measurement of the π0 radiative decay width.

High precision measurements of the differential cross sections for π0 photoproduction at forward angles for two nuclei, 12C and 208Pb, have been performed for incident photon energies of 4.9-5.5 GeV to extract the π0→γγ decay width.

"The air got to it:" exploring a belief about surgery for lung cancer.

Background: The belief that exposure of lung cancer to air during surgery causes tumor spread is prevalent but poorly understood.

Purpose: The purpose of the study was to summarize the published literature on the potential historical origins of this belief, study the recurrence rates of surgically treated stage I nonsmall cell lung cancer, research the mechanisms by which surgery might promote tumor growth and metastasis, and examine the social and cultural implications of this belief.

Data Sources: Various databases, reference lists, and expert contacts were the sources of data.

Measurement of direct f0(980) photoproduction on the proton.

We report on the results of the first measurement of exclusive f_{0}(980) meson photoproduction on protons for E_{gamma}=3.0-3.8 GeV and -t=0.

Search for Theta++ pentaquarks in the exclusive reaction gammap-->K+K-p.

The reaction gammap --> pK+K- was studied at Jefferson Lab with photon energies from 1.8 to 3.8 GeV using a tagged photon beam.

Search for Theta+ (1540) Pentaquark in High-Statistics Measurement of gammap-->K0K+n at CLAS.

The exclusive reaction gammap-->K0K+n was studied in the photon energy range between 1.6 and 3.8 GeV searching for evidence of the exotic baryon Theta+ (1540)-->nK+.

Adrenergic modulation of erythropoiesis following severe injury is mediated through bone marrow stroma.

Background: Severe trauma leads to hematopoietic failure and bone marrow (BM) dysfunction that manifests clinically as a persistent anemia and leukopenia. The impact of severe trauma and its associated hyperadrenergic state on erythropoiesis has not been described. The aim of this study was to demonstrate the effects of adrenergic agonists and antagonists on erythropoiesis, both in normal bone marrow mononuclear cells (BMNC) and stroma-depleted BM.

Acquisition of the functional properties of the transferrin receptor during its biosynthesis.

The properties of the newly synthesized and partially glycosylated forms of the transferrin receptor were examined to determine which co- and post-translational modifications are necessary for the acquisition of transferrin binding activity and transport of the receptor to the cell surface. The nascent transferrin receptor containing core-glycosylated asparagine-linked oligosaccharides does not possess complete intersubunit disulfide bonds, sediments predominantly as a monomer in sucrose density gradients, and shows reduced binding to transferrin-agarose. Within 20-30 min after synthesis, the transferrin receptor acquires the ability to bind to a transferrin-linked affinity column.

Characterization of proteins that associate with an unglycosylated form of the transferrin receptor in A431 cells.

A protein doublet (Mr = 135,000/130,000) was found to coprecipitate with an unglycosylated form of the transferrin receptor in tunicamycin-treated A431 cells. This doublet is not detected with either a monoclonal or polyclonal antibody to the transferrin receptor on Western blots indicating that these proteins do not interact directly with transferrin receptor antibody. Proteolytic digestion patterns of the individual proteins of the Mr = 135,000/130,000 doublet suggest that they are related to one another and are distinct from the transferrin receptor.
