In this context, various MXenes have shown magnetic properties suitable for applications in spintronics, yet the number of MXenes reported so far is far smaller than their parental MAX phases. Therefore, we have studied the structural, electronic and magnetic properties of bimetallic and vacancy-ordered MXenes derived from a new (VZr)AlC MAX phase to assess whether MXene exfoliation would return stable magnetic materials.

The mutations of PMM2-CDG might lead to the loss of PMM2, which is responsible for the conversion of mannose 6- phosphate into mannose 1-phosphate. Most patients with PMM2-CDG have central nervous system involvement, abnormal coagulation, and hepatopathy.

The pair-like homeobox 2b (PHOX2B) gene is an important transcription factor that regulates cellular proliferation and differentiation in early life. The association between PHOX2B single nucleotide polymorphisms (SNPs) and Wilms tumor risk has not been investigated.

As mutation in the gene is observed in several types of human malignancies, there likely to be similar events that contribute to the pathogenesis of neuroblastoma. We hypothesize that polymorphism in the gene might predispose to neuroblastoma.

Herein, Pt/Ti is used as a buffer layer for the integration of highly oriented crystalline LaBaCoO (LBCO) thin films onto silicon via pulsed laser deposition. LBCO films are highly (00l) oriented with smooth and sharp LBCO/Pt interfaces.

Transition metal dichalcogenides (TMDCs) usually exhibit layered polytypic structures due to the weak interlayer coupling. 2H-NbSe is one of the most widely studied in the pristine TMDC family due to its high superconducting transition temperature (T = 7.3 K) and the occurrence of a charge-density wave (CDW) order below 33 K.

Herein, we investigated the pressure dependence of electric transport in a new type of superconducting metal iridate compound, SrIr, that exhibits a superconducting transition temperature, T , as high as 6.6 K at ambient pressure, in order to complete the T -pressure (p ) phase diagram. Very recently, this sample's superconductivity was discovered by our group, but the superconducting behavior has not yet been clarified under pressure.

Objective: To identify 5'-cytosine-phosphate-guanine-3' in DNA (CpG) sites associated with body mass index (BMI) and examine the temporal relationship between dynamic changes in DNAm and BMI in a longitudinal cohort.
Active use of phase transition phenomena for reversibly tuning the properties of functional materials in devices currently is an attractive research area of materials science. We designed and fabricated two kinds of metasurface modulators for dynamically controlling the wavefront of terahertz (THz) radiation based on the temperature-induced insulator-to-metal phase transition of vanadium dioxide (VO). The modulators designed are based on the C-shaped slot antenna array.

We aimed to provide the characteristics of G6PD deficiency and G6PD gene variant distribution in a large Chinese newborn screening population. We investigated the prevalence of G6PD in China from 2013 to 2017.
View Article and Find Full Text PDFSingle-crystalline SnSe has attracted much attention because of its record high figure-of-merit ≈ 2.6; however, this high has been associated with the low mass density of samples which leaves the intrinsic of fully dense pristine SnSe in question. To this end, we prepared high-quality fully dense SnSe single crystals and performed detailed structural, electrical, and thermal transport measurements over a wide temperature range along the major crystallographic directions.

We analyzed the newborn screening data of HPA, obtained using a fluorometric method and tandem mass spectrometry (MS/MS), from 2013 to 2017. The suspected positive samples were further diagnosed using MassArray technology, multiplex ligation-dependent probe amplification (MLPA), and Sanger sequencing.

This study aimed to determine the clinical, biochemical, and mutation spectrum of patients with IVA from mainland China.
Methods: Eight patients (three boys and five girls) from eight unrelated families were collected, IVD gene mutations and phenotypes were examined.
Neuroblastoma is a heterogeneous cancer frequently occurring in childhood. Germline mutations of oncogene are implicated in several types of cancer. However, whether common single nucleotide polymorphisms (SNPs) in gene are associated with neuroblastoma risk has received relatively few attentions.

Accumulated evidences showed that Wnt/β-catenin pathway plays a role in the pathogenesis of cartilage damage. In addition, it is experimentally documented that lncRNA (long non-coding RNA) HOTAIR plays a key role in the regulation of Wnt/β-catenin pathway based on directly decreased WIF-1 expression.

Background: Wilms tumor, derived from embryonic cells, accounts for a large proportion of pediatric renal tumors. MYCN encoded by MYCN proto-oncogene, a member of the MYC family, is a BHLH transcription factor. It plays a critical role in tumorigenesis and predicts poor clinical outcomes in various types of cancer.

Methods: Genomic DNA was extracted from 190 NTG patients and 201 control subjects. The thirteen exons of were amplified by polymerase chain reaction and analyzed by direct sequencing.
Purpose: The Breast Imaging Reporting and Data System (BI-RADS) lexicon was developed to standardize mammographic reporting to assess cancer risk and facilitate the decision to biopsy. Because of substantial interobserver variability in the application of the BI-RADS lexicon, the decision to biopsy varies greatly and results in overdiagnosis and excessive biopsies. The false-positive rate from mammograms is estimated to be 7% to approximately 10% overall, but within the BI-RADS 4 category, it is greater than 70%.

CCR5 cis-regulatory regions were sequenced, CCR2-V64I and CCR5Δ32 genotyped, and compared in HIV-1-infected black South Africans: 71 HIV-1 controllers (23 elite controllers, 37 viraemic controllers (VCs), 11 high viral load long-term non-progressors) and 74 progressors. The HHE haplotype and 3'UTR +2919 T > G SNP heterozygosity were underrepresented in total controllers and VCs vs.
