Association of Tooth Loss and Diet Quality with Acceleration of Aging: Evidence from NHANES.

Background: Although tooth loss is widely recognized as a typical sign of aging, whether it is associated with accelerated aging, and to what extent diet quality mediates this association are unknown.

Methods: Data were collected from the National Health and Nutrition Examination Survey. The missing tooth counts were recorded as the number of edentulous sites.

Identification of a prognostic 28-gene expression signature for gastric cancer with lymphatic metastasis.

Gastric cancer (GC) patients have high mortality due to late-stage diagnosis, which is closely associated with lymph node metastasis. Exploring the molecular mechanisms of lymphatic metastasis may inform the research into early diagnostics of GC. In the present study, we obtained RNA-Seq data from The Cancer Genome Altas and used Limma package to identify differentially expressed genes (DEGs) between lymphatic metastases and non-lymphatic metastases in GC tissues.

[Prediction of Cadmium Content in the Leaves of Navel Orange in Heavy Metal Contaminated Soil Using VIS-NIR Reflectance Spectroscopy].

Visual and Near-infrared (VIS-NIR) reflectance spectroscopy had been used widely in monitoring agricultural pollution in recent years, however, it was rarely applied in monitoring the contamination of heavy metal in orchards. In the present paper, Newhall navel orange (Citrus sinensis [L.] Osbeck cv.

A photoconductive charge-transfer crystal with mixed-stacking donor-acceptor heterojunctions within the lattice.

A pyrene derivative as the donor and a butyl-viologen as the acceptor were used to construct a novel charge-transfer cocrystal consisting of mixed-stacking structure and having switchable photoconductivity stemming from the donor-acceptor heterojunctions within the lattice.

[Quantitatively determining trace elements Co and Bi in gelatin by inductively coupled plasma atomic emission spectrometry method--applying IEC model to correct the spectral interference of Fe to Co].

By ICP-AES, the authors established the method to quantitatively determine the trace elements Co and Bi in gelatin. The authors processed the unknown sample with wet digesting method. Trace elements in gelatin could be quantitatively determined at the same time.

[A novel mutation causes congenital factor V deficiency].

Objective: To investigate the gene defect in a hereditary coagulation factor V (FV) deficiency family.

Methods: The plasma FV actigen was measured by one-stage clotting assay. The FV antigen was assayed by Biotin-Avidin enzyme linked immunosorbent assay (BA-ELISA).
