PEGylated ultra-small nanographene oxide (usNGO-PEG) has exhibited great potential in nanotheranostics due to its newly-discovered physicochemical properties derived from the rich functional groups and  bonds. Herein, we developed a general, simple and kit-like preparation approach for 99mTcI- and Gd-anchored NGO-PEG using a chelator-free strategy. In this strategy, [99mTcI(CO)3(OH2)3]+ (abbreviated to 99mTcI) and GdCl3 were mixed with usNGO-PEG to yield 99mTc- and Gd-usNGO-PEG via the synergistic coordination of N and O atoms from NGO and PEG with 99mTcI and Gd3+ without additional exogenous chelators...

The development of novel neuroprotective treatments for acute stroke has been fraught with failures, which supports the view of ischemic brain damage as a highly complex multifactorial process. Post-translational modifications such as small ubiquitin-like modifier (SUMO)ylation have emerged as critical molecular regulatory mechanisms in states of both homeostasis and ischemic stress, as evidenced by our previous work. Accordingly, the clinical significance of the selective control of the global SUMOylation process has become apparent in studies of ischemic pathobiology and pathophysiology...

The long-term effects of combined divalent copper (Cu(II)) and tetracycline (TC) on the performance, microbial activity and community in a sequencing batch reactor (SBR) were investigated. The addition of Cu(II), TC or mixed Cu(II)/TC caused the decrease of the organics and nitrogen removal efficiencies, and their decreased degrees were the lowest at the addition of mixed Cu(II)/TC. The increase of mixed Cu(II)/TC concentrations in the influent did not change the antagonistic effects between Cu(II) and TC on nitrifying and denitrifying activities...

BACKGROUND: Long non-coding RNAs (LncRNAs) are non-protein coding transcripts longer than 200 nucleotides in length. Instead of being "transcriptional noise", lncRNAs are emerging as a key modulator in various biological processes and disease development. Mesenchymal stem cells can be isolated from various adult tissues, such as bone marrow and dental tissues. The differentiation processes into multiple lineages, such as osteogenic differentiation, are precisely orchestrated by molecular signals in both genetic and epigenetic ways...

BACKGROUND/AIMS: β-catenin is an integral component of the canonical Wnt signaling pathway, and its mutations are an autosomal recessive cause of colorectal cancer (CRC), medulloblastoma (MDB), and ovarian cancer. Nevertheless, little is known about its function in lung cancers. METHODS: We first knocked down β-catenin by siRNA to investigate its effects on lung cancer cell proliferation, migration and apoptosis. Then we verified the interaction between β-catenin and CREB binding protein (CBP) by immunofluoresence and co-immunoprecipition assays...

Large scale epitaxial growth and transfer of monolayer MoS2 has attracted great attention in recent years. Here, we report the wafer-scale epitaxial growth of highly oriented continuous and uniform monolayer MoS2 films on single-crystalline sapphire wafers by chemical vapor deposition (CVD) method. The epitaxial film is of high quality and stiched by many 0°, 60° domains and 60°-domain boundaries. Moreover, such wafer-scale monolayer MoS2 films can be transferred and stacked by a simple stamp-transfer process and the substrate is reusable for subsequent growth...

AIM: Pulmonary arterial hypertension (PAH), a deadly disorder is associated with excessive growth of human pulmonary artery endothelial (HPAECs) and smooth muscle (HPASMCs) cells. Current therapies primarily aim at promoting vasodilation, which only ameliorates clinical symptoms without a cure. 2-(1'H-indole-3'-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE) is an endogenous aryl hydrocarbon receptor (AhR) ligand, and mediates many cellular function including cell growth. However, the roles of ITE in human lung endothelial cells remain elusive...

Miyoshi myopathy (MM) is an autosomal recessive distal muscular dystrophy caused by mutations in the dysferlin gene (DYSF), a 150-kb gene on chromosome 2p13 that contains 55 coding exons. Many patients with MM harbour mutations in the DYSF gene, and most of these mutations are inherited from the patients' parents. Recently, we encountered novel, de novo mutations in the DYSF gene in a patient with MM. DYSF gene analysis was performed by targeted next-generation sequencing, and we found that the patient had compound heterozygous mutations, including a de novo mutation (c...

A series of arylalkanol and aralkyl piperazine derivatives have been synthesized and evaluated for 5-HT reuptake inhibitory abilities and binding affinities at the 5-HT1A/5-HT7 receptors. Antidepressant activities of the compounds in vivo were screened using the forced swimming test (FST). The results indicated that the compound 8j exhibited high affinities for the 5-HT1A/5-HT7 receptors (5-HT1A, ki = 0.84 nM; 5-HT7, ki = 12 nM) coupling with moderate 5-HT reuptake inhibitory activity (RUI, IC50 = 100 nM) and showed a marked antidepressant-like activity in the FST model...

Quantum dots (QDs) are semiconducting nanocrystals with unique optical properties. When coated with shell/capping, QDs are not deleterious to cells and organisms. However, when QDs are retained in the cellular environment for a certain period of time, their coatings may be degraded, yielding "naked" QDs. Although some studies have documented the acute effects of QDs in various cell lines, however, to our knowledge, there are no published studies on the chronic effects of QDs in normal lung cells. In this study, we therefore sought to study the effects of cadmium telluride (CdTe) QDs of various particles sizes on their cytotoxicity and carcinogenicity in normal human bronchial epithelial cells (BEAS-2B)...

BACKGROUND: Whether perioperative blood transfusions (PBTs) adversely influence oncological outcomes for intrahepatic cholangiocarcinoma (ICC) patients after curative resection remains undetermined. METHODS: Of the 605 patients who underwent curative liver resection for ICC between 2000 and 2012, 93 received PBT. We conducted Cox regression and variable selection logistic regression analyses to identify confounding factors of PBT. Propensity score matching (PSM) and Cox regression analyses were used to compare the overall survival (OS) and disease-free survival (DFS) between the patients with or without PBT...
