Stabilizing High-Temperature α-LiPS by Rapidly Heating the Glass.

High-temperature metastable phases exhibit superior characteristics compared to those of thermodynamically stable phases at room temperature. Although optimization of the compositions and crystallizations from glasses contribute to the stabilization of metastable phases at room temperature, the stabilization of the high-temperature α-LiPS phase is not yet reported. α-LiPS was successfully stabilized at room temperature, instead of the middle-temperature β-LiPS phase, rapid heating to crystallize the LiPS glass.

Printed Organic Transistor-based Biosensors for Non-invasive Sweat Analysis.

This review describes recent advances in biosensors for non-invasive human healthcare applications, especially focusing on sweat analysis, along with approaches for fabricating these biosensors based on printed electronics technology. Human sweat contains various kinds of biomarkers. The relationship between a trace amount of sweat biomarkers partially partitioned from blood and diseases has been investigated by omic analysis.

Noninvasive Sweat-Lactate Biosensor Emplsoying a Hydrogel-Based Touch Pad.

This study is the first report demonstrating proof-of-concept for a hydrogel-based touch sensor pad used for the non-invasive extraction and detection of sweat components. The sensor device was composed of an electrochemical L-lactate biosensor covered with an agarose gel in a phosphate buffer saline. When human skin contacts the agarose gel, L-lactate in sweat was continuously extracted into the gel, followed by in-situ potentiometric detection without controlled conditions.

A critical role of the small GTPase Rac1 in Akt2-mediated GLUT4 translocation in mouse skeletal muscle.

Insulin promotes glucose uptake in skeletal muscle by inducing the translocation of the glucose transporter GLUT4 to the plasma membrane. The serine/threonine kinase Akt2 has been implicated as a key regulator of this insulin action. However, the mechanisms whereby Akt2 regulates multiple steps of GLUT4 translocation remain incompletely understood.

Distinct contributions of vacuolar Qabc- and R-SNARE proteins to membrane fusion specificity.

In eukaryotic endomembrane systems, Qabc-SNAREs (soluble N-ethylmaleimide-sensitive factor attachment protein receptors) on one membrane and R-SNARE on the opposing membrane assemble into a trans-QabcR-SNARE complex to drive membrane fusion. However, it remains ambiguous whether pairing of Qabc- and R-SNAREs mediates membrane fusion specificity. Here, we explored the fusion specificity of reconstituted proteoliposomes bearing purified SNAREs in yeast vacuoles and other organelles.

Enhanced carbonyl stress in a subpopulation of schizophrenia.

Context: Various factors are involved in the pathogenesis of schizophrenia. Accumulation of advanced glycation end products, including pentosidine, results from carbonyl stress, a state featuring an increase in reactive carbonyl compounds (RCOs) and their attendant protein modifications. Vitamin B(6) is known to detoxify RCOs, including advanced glycation end products.

Potentiation of proliferation of some but not all human colon carcinoma cell lines by immobilized hepatic asialoglycoprotein receptor 1.

Twenty-three human colorectal carcinoma cell lines were examined for the binding of recombinant hepatic asialoglycoprotein receptor 1 (ASGR1), which is known to be exclusively expressed on hepatic parenchymal cells. The effects of the binding were assessed by adhesion to and proliferation on immobilized recombinant ASGR1. Recombinant ASGR1 bound strongly to six cell lines and moderately to 15 cell lines out of 23 lines tested, as shown by flow cytometric analysis.

[Usefulness of fentanyl patch (Durotep) in cancer patients when rotated from morphine preparations].

Background: [corrected] The transdermal fentanyl patch (Durote patch) is an opioid preparation requiring replacement once in three days, which is occasionally prescribed to replace morphine preparations. The conversion ratio from morphine to fentanyl has been claimed to be 100:1 or 150:1, but there may exist individual variations.

Methods: We retrospectively evaluated the analgesic effects and adverse effects of fentanyl patch in 24 cases among 22 patients (11 men and 11 women).

Properties of blocking and non-blocking monoclonal antibodies specific for human macrophage galactose-type C-type lectin (MGL/ClecSF10A/CD301).

Monoclonal antibodies (mAbs) specific for the human macrophage galactose-type calcium-type lectin (MGL) were established. The recombinant extracellular domain of MGL was used to immunize a mouse, and 10 hybridoma clones were obtained. Binding of recombinant MGL to asialo-bovine submaxillary mucin was shown to be blocked by mAbs MLD-1, 4 and 6.

Gene expression regulation following behavioral sensitization to cocaine in transgenic mice lacking the glucocorticoid receptor in the brain.

Several findings suggest that glucocorticoid hormones influence the propensity of an individual to develop cocaine abuse. These hormones activate two related transcription factors, the glucocorticoid receptor and the mineralocorticoid receptor. We have shown previously that mice carrying a mutation of the glucocorticoid receptor gene specifically in neural cells, glucocorticoid receptor knock-out in the brain, show a dramatic decrease in cocaine-induced self-administration and no behavioral sensitization to this drug, two experimental procedures considered relevant models of addiction.

The glucocorticoid receptor as a potential target to reduce cocaine abuse.

Several findings suggest that glucocorticoid hormones are involved in determining the propensity of an individual to develop cocaine abuse. These hormones activate two related transcription factors, the glucocorticoid receptor (GR) and the mineralocorticoid receptor. In this study, we show that the selective inactivation of the GR gene in the brains of mice profoundly flattened the dose-response function for cocaine intravenous self-administration and suppressed sensitization, two experimental procedures considered relevant models of addiction.

Spatio-temporal disintegration of visual perception in schizophrenia as revealed by a novel cognitive task, the Searchlight Test.

We developed a novel computer-assisted psychological test (the Searchlight Test) in order to explore 'cognitive fragmentation' and its relation to thought disorder in schizophrenic patients. Participants were instructed to search geometric figures through a small hole (3 cm in diameter) on a display monitor by moving a mouse device and to reconstruct an image of the whole from the temporally and spatially fragmented visual stimuli.The cognitive function measures in 24 schizophrenic patients and 14 normal controls showed that the error rates of the recall task (drawing the figure from memory) and the recognition task (selecting the correct figure from several similar figures) were significantly higher in schizophrenic patients than in normal controls.

Axon collaterals of mossy fibers from the pontine nucleus in the cerebellar dentate nucleus.

1. Single axons of pontine nucleus neurons (PN axons) receiving cerebral input were stained intra-axonally with horseradish peroxidase (HRP) in the cerebellum of cats. The axonal trajectory of single PN axons was reconstructed from serial sections of the cerebellum and the brain stem.
