Nonunitary superconductivity is a rare and striking phenomenon in which spin up down electrons segregate into two different quantum condensates. Because they support topological excitations, such superconductors are being seriously considered for potential information applications. We report the discovery of nonunitary spin-triplet UTe2, featuring high transition temperature 1.6 K remarkably large anisotropic upper critical field exceeding 40 T. In this unusual superconducting state, with...
Vitamin K (K) is essential for blood coagulation and bone metabolism in mammals. acts as a cofactor the posttranslational synthesis of gamma-carboxyglutamic acid from glutamic residues. In addition to liver bone, found brain, heart, kidney gonadal tissue. However, physiological role these various organs not yet fully understood. It likely that has functions other than its protein gamma-glutamyl carboxylation. We used this study DNA microarray technique identify effect status on gene...
Collagen, a major extracellular matrix macromolecule, is widely used for biomedical purposes. We investigated the absorption mechanism of low molecular weight collagen hydrolysate (LMW-CH) and its effects on osteoporosis in rats. When administered to Wistar rats with either [(14)C]proline (Pro group) or glycyl-[(14)C]prolyl-hydroxyproline (CTp group), LMW-CH rapidly increased plasma radioactivity. was absorbed into blood peptide form. Glycyl-prolyl-hydroxyproline tripeptide remained...

In a nutshell: A 4.3 nm core–shell aggregate of 16 polyoxotungstate building units (see picture the W/Mn skeleton) delineates upper limit for structural complexity in molecular metal oxide cluster chemistry to date. This structure is defined by backbone network dual MnOW bridges; retroanalysis their formation suggests importance templation and kinetic control self-assembly {MnIII40WVI224} polyanion.

In tetragonal ${\mathrm{SrCo}}_{2}{\mathrm{As}}_{2}$ single crystals, inelastic neutron scattering measurements demonstrated that strong stripe-type antiferromagnetic (AFM) correlations occur at a temperature $T=5$ K [Jayasekara et al., arXiv:1306.5174] are the same as in isostructural $A{\mathrm{Fe}}_{2}{\mathrm{As}}_{2}$ ($A$ $=$ Ca, Sr, Ba) parent compounds of high-${T}_{\mathrm{c}}$ superconductors. This surprising discovery suggests may also be good compound for superconductivity. Here...
Magnetism is widely considered to be a key ingredient of unconventional superconductivity. In contrast cuprate high-temperature superconductors, antiferromagnetism in Fe-based superconductors (FeSCs) characterized by pair magnetic propagation vectors. Consequently, three different types order are possible. Of theses, only stripe-type spin-density wave (SSDW) and spin-charge-density (SCDW) orders have been observed. A realization the proposed spin-vortex crystal (SVC) noticeably absent. We...
PbCuTe2O6 is a rare example of spin liquid candidate featuring three dimensional magnetic lattice. Strong geometric frustration arises from the dominant antiferromagnetic interaction which generates hyperkagome network Cu2+ ions although additional interactions enhance lattice connectivity. Through combination magnetization measurements and local probe investigation by NMR muSR down to 20 mK, we provide robust evidence for absence freezing in ground state. The susceptibility probed shift...
The therapeutic efficacy of biotin was evaluated in 43 patients with non-insulin dependent diabetes mellitus. serum concentration the significantly lower than that 64 healthy control subjects and inversely correlated fasting blood glucose level. oral administration biotin, 9mg daily, corrected hyperglycemia no change their insulin levels pyruvate lactate decreased to normal ranges after administration. These observations suggest ameliorates abnormal metabolism diabetic patients, presumably...
We present a bioactuator powered by insect dorsal vessel tissue which can work for long time at room temperature without maintenance. Previously reported bioactuators exploit contracting ability of mammalian heart muscle cell have required precise environmental control to keep the alive and contracting. To overcome this problem, we propose using tissue. The grow is generally robust over range culture conditions compared tissues cells. First, confirm that lepidoptera larva Ctenoplusia agnata...
