Recently, the main therapy of medullary thyroid cancer (MTC) is surgical, but by which way there is a poor prognosis with a mean survival of only 5 years. In some cases, some researchers found that it is the medullary thyroid cancer stem cells (MTCSCs) that cause metastasis and recurrence. This study aimed to eradicate MTCSCs through administration of all-trans-retinoic acid (ATRA). Here we demonstrate that MTCSCs possess stemlike properties in serum-free medium. The ABCG2, OCT4 and sodium iodide symporter (NIS) were changed by ATRA. Additionally, we found that ATRA can increase the expression of NIS in vivo. All the data suggested that ATRA could increase the iodine uptake of MTCSCs through NIS.

Objective: The present study was to investigate the association of polymorphisms in exon-9 of the bone morphogenetic protein receptor-1B (BMPR-1B) gene (C864T) with litter size in 240 Dorset, 232 Mongolian, and 124 Small Tail Han ewes. Methods: Blood samples were collected from 596 ewes and genomic DNA was extracted using the phenol: chloroform extraction method. The 304-bp amplified polymerase chain reaction product was analyzed for polymorphism by single-strand conformation polymorphism method. The genotypic frequency and allele frequency of BMPR-1B gene exon-9 were computed after sequence alignment. The χ2 independence test was used to analyze the association of genotypic frequency and litter size traits with in each ewe breed, where the phenotype was directly treated as category. Results: The results indicated two different banding patterns AA and AB for this fragment, with the most frequent genotype and allele of AA and A. Calculated Chi-square test for BMPR-1B gene exon-9 was found to be more than that of p value at the 5% level of significance, indicating that the population under study was in Hardy-Weinberg equilibrium for all ewes. The χ2 independence test analyses indicated litter size differences between genotypes was not the same for each breed. The 304-bp nucleotide sequence was subjected to BLAST analysis, and the C864T mutation significantly affected litter size in singletons, twins and multiples. The heterozygosity in exon-9 of BMPR-1B gene could increase litter size for all the studied ewes. Conclusion: Consequently, it appears that the polymorphism BMPR-1B gene exon-9 detected in this study may have potential use in marker assisted selection for litter size in Dorset, Mongolian, and Small Tail Han ewes.

Aims: Chronic hepatitis C virus (HCV) infection remains a major health threat in China, affecting at least 10 million people, with approximately 58% having genotype (GT) 1 infection. There is a critical need for simple, all oral, direct-acting antiviral regimens to treat GT1 HCV in this region. Treatment with ledipasvir (LDV)/sofosbuvir (SOF) results in high sustained virologic response rates 12 weeks after therapy (SVR12) in GT1 HCV infected patients in clinical trials and real-world settings. This study evaluated the efficacy and safety of LDV/SOF for 12 weeks in Chinese patients with chronic GT1 HCV infection. Methods: Treatment experienced and treatment naïve patients with chronic GT1 HCV infection with no cirrhosis or with compensated cirrhosis were eligible to enroll in a single-arm, openlabel trial to receive a fixed dosed combination of LDV/SOF 90/400 mg daily for 12 weeks. The primary efficacy endpoint was SVR12 using the CAP/CTM HCV 2.0 assay (LLOQ =15 IU/mL) and the primary safety endpoint was adverse events (AEs) leading to LDV/SOF discontinuation. Results: A total of 206 Chinese patients were enrolled and treated. Of these, 50% were male, 16% had compensated cirrhosis, 49% were treatment-experienced, 76% had IL28B CC genotype, and 100% had GT1b HCV infection. The mean (range) age and body mass index of enrolled subjects were 47 (21-72) years and 23 (14-34) kg/m2, respectively. The overall SVR12 rate is 100% (206/206). All 32 patients with cirrhosis (15 of whom were treatment-experienced), achieved SVR12. There were no discontinuations due to AEs. No serious or severe AEs were assessed by the investigator as related to study drug and there were no deaths. Conclusions: Treatment with the single tablet regimen of LDV/SOF for 12 weeks resulted in 100% SVR12 and was well tolerated in treatment experienced and treatment naïve GT1 HCVinfected Chinese patients with and without cirrhosis.

The design and synthesis of new hydrogen storage nanomaterials with high capacity at low cost is extremely desirable but remains challenging for today's development of a hydrogen economy. As a new type hydrogen storage material, Co(OH)2/rGO nanocomposites were successfully obtained through a facile method in this study. Through the measurements of X-ray diffraction, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), cyclic voltammetry and galvanostatic charge/discharge, it indicated that Co(OH)2/rGO nanocomposites showed a veil-like microstructure, consisting of interlaced nanorods with a diameter of 4–8 nm on rGO nanosheets. The hydrogen storage capacity was up to 400 mAh/g at room temperature, higher than those of graphene and Co(OH)2.

<P/><P>Substrate-mediated gene delivery is a promising method due to its unique ability to preconcentrate exogenous genes onto designated substrates. However, many challenges remain to enable continuous and multiround delivery of the gene using the same substrates without depositing payloads and immobilizing cells in each round of delivery. Herein we introduce a gene delivery system, nanosubstrate-mediated delivery (NSMD) platform, based on two functional components with nanoscale features, including (1) DNA⊂SNPs, supramolecular nanoparticle (SNP) vectors for gene encapsulation, and (2) Ad-SiNWS, adamantane (Ad)-grafted silicon nanowire substrates. The multivalent molecular recognition between the Ad motifs on Ad-SiNWS and the β-cyclodextrin (CD) motifs on DNA⊂SNPs leads to dynamic assembly and local enrichment of DNA⊂SNPs from the surrounding medium onto Ad-SiNWS. Subsequently, once cells settled on the substrate, DNA⊂SNPs enriched on Ad-SiNWS were introduced through the cell membranes by intimate contact with individual nanowires on Ad-SiNWS, resulting in a highly efficient delivery of exogenous genes. Most importantly, sequential delivery of multiple batches of exogenous genes on the same batch cells settled on Ad-SiNWS was realized by sequential additions of the corresponding DNA⊂SNPs with equivalent efficiency. Moreover, using the NSMD platform <I>in vivo</I>, cells recruited on subcutaneously transplanted Ad-SiNWS were also efficiently transfected with exogenous genes loaded into SNPs, validating the <I>in vivo</I> feasibility of this system. We believe that this nanosubstrate-mediated delivery platform will provide a superior system for <I>in vitro</I> and <I>in vivo</I> gene delivery and can be further used for the encapsulation and delivery of other biomolecules.</P>

The diverse microbial communities that colonize distinct segments of the gastrointestinal tract are intimately related to aspects of physiology and the pathology of human health. However, most recent studies have focused on the rectal or fecal microbiota, and the microbial signature of the duodenum is poorly studied. In this study, we compared the microbiota in duodenal and rectal samples to illustrate the characteristic microbial signatures of the duodenum in healthy adults. Nine healthy volunteers donated biopsies and luminal contents from the duodenum and rectum. To determine the composition and diversity of the microbiota, 454- pyrosequencing of bacterial 16S rRNA was performed and multiple bioinformatics analyses were applied. The α-diversity and phylogenetic diversity of the microbiota in the duodenal samples were higher than those of the rectal samples. There was higher biodiversity among the microbiota isolated from rectal biopsies than feces. Proteobacteria were more highly represented in the duodenum than in the rectum, both in the biopsies and in the luminal contents from the healthy volunteers (38.7% versus 12.5%, 33.2% versus 5.0%, respectively). Acinetobacter and Prevotella were dominant in the duodenum, whereas Bacteroides and Prevotella were dominant in the rectum. Additionally, the percentage of OTUs shared in biopsy groups was far higher than in the luminal group (43.0% versus 26.8%) and a greater number of genera was shared among the biopsies than the luminal contents. Duodenal samples demonstrated greater biological diversity and possessed a unique microbial signature compared with the rectum. The mucosa-associated microbiota was more relatively conserved than luminal samples.
