The severe and nonsevere models' prediction performances were better than that of the mixed model. The mean squared errors were lower than 0.05 l
, and the decision coefficients (R
) were higher than 0.40. The two-tailed t-test results showed that for both severe and nonsevere models, the absolute percentage errors of FEV
and FVC were within 10%.

The integration of the rectifying effect with resistance switching has been considered feasible to suppress the sneaking current. Herein, we report a self-rectifying resistance switching (SR-RS) by a newly discovered Li ions migration induced dynamic p-n junction at the Li-doped ZnO and ZnO layer interface. The Au/Li-ZnO/ZnO/Pt structure exhibits a forming-free and stable resistance switching with a high resistance ratio of R OFF/R ON ∼ 104 and a large rectification ratio ∼106. In the Li-ZnO/ZnO bilayer, the electric field drives the dissociation and recombination of the self-compensated [Formula see text] complex pairs ([Formula see text] p-type substitutional defect; [Formula see text] n-type interstitial defect) through the transport of [Formula see text] between the two layers, thereby induces the formation of a dynamic p-n junction. Using this structure as a memory stacking device, the maximum crossbar array size has been calculated to be ∼16 Mbit in the worst-case scenario, which confirms the potential of the proposed device structure for the selection-device free and high-density resistance random access memory applications.Microfluidic-based fluorescent exclusion method allows to tackle the issue of neuronal growth from a volume perspective. Based on this technology, we studied the two main actin-rich structures accompanying the early stages of neuron development, i.e. growth cones, located at the tip of growing neuronal processes, and propagative actin waves. Our work reveals that growth cones tend to loose volume during their forward motion, as do actin waves during their journey from the cell body to the tip of neuronal processes, before the total transfer of their remaining volume to the growth cone. Actin waves seem thus to supply material to increasingly distant growth cones as neurons develop. In addition, our work may suggest the existence of a membrane recycling phenomena associated to actin waves as a pulsatile anterograde source of material and by a continuous retrograde transport.Silicon is a promising anode for new-generation lithium ion batteries due to high theoretical lithium storage capacity (4200 mAh g-1). However, the low conductivity and large volumetric expansion hamper the commercialization of the silicon anode. In this case, we present a yolk-void-shell Si-C anode (denoted as Si@Void@C), which is synthesized through nano-Si oxidation, surface carbonization and etching of SiO x . The void can be fabricated only by the self-generation and etching of SiO x layer on the Si surface, without the help of template materials. Moreover, the void size can be adjusted only by means of the annealing temperature, which can be easily and precisely operated. The Si@Void@C/rGO with void size of 5 nm offers a discharge capacity of 1294 mAh g-1 after 100 cycles at a current density of 500 mA g-1. These enhanced performances can be ascribed to an appropriate size (5 nm) of void space which sufficiently accommodates the silicon volume expansion and stabilizes the carbon shell. At the same time, the voids effectively inhibit the growth of the solid electrolyte interface layer by depressing the decomposition of the electrolyte on the surface of Si in Si@Void@C/rGO. Furthermore, interfaces between Si@Void@C particles and rGO sheets construct bridges for electrons' conduction. In general, the present work provides a viable strategy for synthesizing silicon-carbon anode materials with long life.Identifying cerebral vulnerability in late life may help prevent or slow the progression of aging-related chronic diseases. However, non-invasive biomarkers aimed at detecting subclinical cerebral changes in the elderly are lacking. Here, we have examined the potential of plasma total tau (t-tau) for identifying cerebral and cognitive deficits in normal elderly subjects. Patterns of cortical thickness and cortical glucose metabolism were used as outcomes of cerebral vulnerability. We found that increased plasma t-tau levels were associated with widespread reductions of cortical glucose uptake, thinning of the temporal lobe, and memory deficits. Importantly, tau-related reductions of glucose consumption in the orbitofrontal cortex emerged as a determining factor of the relationship between cortical thinning and memory loss. Together, these results support the view that plasma t-tau may serve to identify subclinical cerebral and cognitive deficits in normal aging, allowing detection of individuals at risk for developing aging-related neurodegenerative conditions.
Long non-coding RNAs (LncRNAs) have been associated with several types of cancer. selleck chemicals llc However, little is known about their role in lung adenocarcinoma (LUAD).
LINC00968 was significantly differentially expressed in LUAD tissues. Downregulated LINC00968 was associated with clinicopathological features of LUAD. LINC00968 inhibited cell growth and metastasis by regulating the Hippo signaling pathway We demonstrated that LINC00968 acts as a ceRNA to consume miR-21-5p, enhancing the accumulation of SMAD7, a miR-21-5p target.
LINC00968 limits LUAD progression via the miR-21-5p/SMAD7 axis and may serve as a prognostic biomarker and therapeutic target for LUAD.
We conducted comprehensive data mining on LINC00968 based on the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) database. The expression of LINC00968 in LUAD cells was determined using
