Hypomagnesemia is frequently seen after transplantation and is particularly associated with the use of calcineurin inhibitors (CNIs).

We conducted a retrospective, single-center analysis (2000-2013, N = 726) to explore the relationship between hypomagnesemia and long-term allograft outcome in kidney transplant recipients. For this study, a median serum magnesium (Mg) level of all measured Mg levels from 1 month to 1 year after renal transplantation was calculated.

For every increase in Mg by 0.1 mg/dL, the GFR decreased by 1.1 mL/min at 3 years posttransplant (p < 0.01) and by 1.5 mL/min at 5 years posttransplant. A median blood Mg level of ≥1.7 was found to be an independent predictor of a GFR <60 mL/min at 3 years posttransplant. The odds of having a GFR <60 mL/min 3 years posttransplant was almost 2-fold higher in the high Mg group than in the low Mg group.

Hypomagnesemia from 1 to 12 months after renal transplantation is associated with a better allograft function up to 5 years posttransplant. This relationship was found to hold true after accounting for baseline allograft function and the presence of slow graft function.

Phys. J. B 92 93 and 2020 Phys. Rev. B 101 094427) to characterize the unusual behavior of the magnetic spectrum, magnetization and magnetic susceptibility of the molecular magnet Ni4Mo12. The theoretical background is based on the molecular orbital theory in conjunction with the multi-configurational self-consistent field method and results in a post-Hartree-Fock scheme for constructing the corresponding energy spectrum. Furthermore, we construct a bilinear spin-like Hamiltonian involving discrete coupling parameters accounting for the relevant spectroscopic magnetic excitations, magnetization and magnetic susceptibility. The explicit expressions of the eigenenergies of the ensuing Hamiltonian are determined and the physical origin of broadening and splitting of experimentally observed peaks in the magnetic spectra is discussed. To demonstrate the efficiency of our method we compute the spectral properties of a spin-one magnetic dimer. The present approach may be applied to a variety of magnetic units based on transition metals and rare Earth elements.Exosomal microRNAs (miRNAs) have attracted great attention as predictive and prognostic biomarkers of cancer. #link# Profiling of miRNAs plays a key role in the effective diagnosis of cancers. However, simultaneous quantification of multiple miRNAs is challenging due to their homology and low abundance especially in exosomes. Here, we developed a sensitive detection method for multiple exosomal miRNAs with the help of rolling circle amplification (RCA). In contrast of the traditional ways, this method takes the advantages of both the multiplex sensing ability and the simplicity of RCA. Specifically, multiple exosomal miRNAs from different cell lines were replicated simultaneously through RCA and detected using designed molecular beacons (MBs). miRNA-21, miRNA-122 and miRNA-155 were chosen as the targets, which are overexpressed in cancers. Normalized fluorescence intensities of MB were used to imply the relative concentrations of these miRNAs. The obtained relative miRNAs expression levels could be used to distinguish the breast cancer exosome from normal one. If the varieties of the detected exosomal miRNAs are abundant enough, the concentration ratios of miRNAs could basically indicate the corresponding exosome and exosome screening could be realized. Such exosomal miRNA profiling and exosome screening can assist cancer diagnosis, which is promising in clinical application.This work reports experimental and computational magnetic phase transition from superconducting-diamagnet to ferromagnet in lanthanum (La)-doped functionalized Nb2C MXene. Co-precipitation method is used to synthesize La-doped Nb2C MXene. Structure and morphology of the compound are studied through x-ray diffraction, scanning electron microscopy, high-resolution transmission electron microscopy and energy dispersion spectroscopy, confirming the successful doping of La while retaining the two-dimensional (2D) structure of MXene. The magnetic properties of doped sample are studied using field-cooled and zero-field-cooled curves as well as from magnetization (M) versus applied magnetic field (H) graphs. Contrary to the superconductivity-like diamagnetic behavior in pristine Nb2C MXene, the La-doped MXene converts the diamagnetism into the ferromagnetic (FM) phases at all temperatures. The ferromagnetism arises due to the pinning of magnetic spins pinned by Lanthanum itself. The computational analysis of pristine Nb2C MXene confirms its diamagnetic behavior and further clarifies the role of La and functional groups (O and F) in the reduction of diamagnetic behavior in La-doped Nb2C MXene while inducing FM nature. This work provides an interesting superconducting-diamagnetic to FM transition with a possibility of its implementation in 2D spintronics.Understanding and tuning of metal-insulator transition (MIT) in oxide systems is an interesting and active research topics of condensed matter physics. We report thickness dependent MIT in Ga-doped ZnO (GaZnO) thin films grown by pulsed laser deposition technique. From the electrical transport measurements, we find that while the thinnest film (6 nm) exhibits a resistivity of 0.05 Ω cm, lying in the insulating regime, the thickest (51 nm) has resistivity of 6.6 × 10-4 Ω cm which shows metallic type of conduction. Our analysis reveals that the Mott's variable range hopping model governs the insulating behavior in the 6 nm film whereas the 2D weak localization (WL) phenomena is appropriate to explain the electron transport in the thicker GaZnO films. Magnetoresistance study further confirms the presence of strong localization in 6 nm film while WL is observed in 20 nm and above thicker films. From the density functional calculations, it is found that due to surface reconstruction and Ga doping, strong crystalline disorder sets in very thin films to introduce localized states and thereby, restricts the donor electron mobility.We exploit the inter-subject similarity of inhomogeneous static magnetic field patterns arising in the human brain under MRI examination to design a small set of shim coils providing performance equivalent to numerous coils based on high-order Spherical Harmonics corrections. A hundred brain B 0-maps were first collected at 3 T. link2 Ideal subject-specific electric current density stream functions are then computed with low power constraints, on a cylindrical surface. This step is repeated over tens of brain maps so that a Principal Component Analysis can be applied to the stream functions; the main components result in the small set of coils. Both 50-subject hold-out and 10-fold cross-validation are employed to evaluate consistency of the proposed system performance over a posteriori subjects. Simulations show that only three cylindrical coils manage to capture the principal magnetic field profiles in the human brain, thus providing a better static field inhomogeneity mitigation than that obtained from 16 unlimited-power high-order Spherical Harmonics coils, with inhomogeneity greatly reduced in the pre-frontal cortex compared to 2nd-order shimmed baseline field acquisitions. The approach provides a very reduced channel count system for mitigating complex B 0-inhomogeneity patterns. Thus, a compact, cost-effective system could be conceived and driven by relatively low-budget electronics. The method should therefore have a strong impact in both ultra-high and portable low-field MRI/MRS. Moreover, this technique can be applied to the design of shim coils addressing anatomies other than the brain.In this study, the interactions between spin wave (SW) and stacked domain walls in a magnetic nanostrip are investigated via micromagnetic simulation. OTX008 mw is found that under the excitation of SW, the metastable TWVW structure consisting of a transverse wall (TW) and a vortex wall (VW) may transform into a 360° wall or may completely annihilate depending on the frequency and amplitude of the SW. In contrast, stacked TWs (STWs) structure shows good robustness. Similar to a single TW, the STWs can be moved by SW and the inside TWs exhibit coherent motions. Notably, the frequency dependence of STWs' velocity demonstrates obvious emergence, shift and disappearance of the resonant peaks. Such changes are found to be in accordance with SW reflection, which thus agrees with the mechanism of linear momentum transfer torque (LMTT). In concern with the SW transmission through STWs, we show that by varying TWs number and SW frequency, a wide range of transmission efficiency η can be obtained. At certain frequencies, η may increase with TWs number and may go beyond 100%, which indicates a lowered attenuation by STWs. On the other hand, the phase shift of the transmitted SW always increases linearly with the TWs number and can be resonantly enhanced at frequencies same as that of TWs normal modes. link3 Mapping of SW reveals that the phase shift is a result of fast propagation of SW through TWs. The fast propagation and the low attenuation of SW through STWs suggests that STWs may serve as an excellent SW channel. Meanwhile, the induced STWs motion and the controlled SW transmission and phase shift by STWs also promises great uses of STWs in future magnonic devices and domain wall devices.Bubble velocity of gas-liquid two-phase flow in coalbed methane well is an key parameter for formulating coalbed methane drainage technology. In this paper, a self-powered bubble velocity sensor (GLT-TENG) of two-phase flow, which is composed of distributed copper electrodes and low-density polyethylene wrapped in an outer layer, is proposed and analyzed based on triboelectric nanogenerator. Test results show that the measurement range is 0-0.49 m s-1 with a measurement error less than 6% when the GLT-TENG is used to measure a single bubble, but the measurement errors are inversely proportional to the time interval (the ratio of distance to speed difference) between the two bubbles when the GLT-TENG is used to measure continuous bubbles, and the measurement accuracy can reach 100% when the bubble time interval is greater than 0.3 s. The maximum output can be achieved when the bubble velocity impulse is 6200 cm3 · cm s-1, that is, the maximum output voltage and current are 0.38 V and 6.3 nA, respectively, and the maximum output power is 0.
