A luminescent CuIPS-type binuclear complex and its fluorescence sensing for pyridine.

Luminescent Cu complexes are an important class of coordination compounds due to their relative abundance, low cost and ability to display excellent luminescence. The title CuIPS-type binuclear complex, di-μ-iodido-bis[(thiourea-κS)(triphenylphosphine-κP)copper(I)], [CuI(CHNS)(CHP)], conventionally abbreviated as CuITPPTU, where TPP and TU represent triphenylphosphine and thiourea, respectively, is described. In this complex, each Cu atom adopts a CuIPS four-coordination mode and pairs of atoms are connected to each other by two μ-I ligands to form a centrosymmetric binuclear cluster.

The interplay of psychological resilience and adolescent mobile phone addiction in Henan province, China: insights from latent class analysis.

Background: The aim of this study was to classify distinct subgroups of adolescents based on the severity levels of their mobile phone addiction and to investigate how these groups differed in terms of their psychosocial characteristics. We surveyed a total of 2,230 adolescents using three different questionnaires to assess the severity of their mobile phone addiction, stress, anxiety, depression, psychological resilience, and personality. Latent class analysis was employed to identify the subgroups, and we utilized Receiver Operating Characteristic (ROC) curves and multinomial logistic regression for statistical analysis.

Identification of IRAK1BP1 as a candidate prognostic factor in lung adenocarcinoma.

Introduction: Lung cancer is one of the major causes of cancer-related mortality worldwide. High-throughput RNA sequencing (RNA-seq) of surgically removed tumors has been used to identify new biomarkers of lung cancer; however, contamination by non-tumor cells in the tumor microenvironment significantly interferes with the search for novel biomarkers. Tumor organoids, as a pre-clinical cancer model, exhibit similar molecular characteristics with tumor samples while minimizing the interference from other cells.

Asymmetric Cell Division and Tumor Heterogeneity.

Asymmetric cell division (ACD) gives rise to two daughter cells with different fates after mitosis and is a fundamental process for generating cell diversity and for the maintenance of the stem cell population. The cancer stem cell (CSC) theory suggests that CSCs with dysregulated self-renewal and asymmetric cell division serve as a source of intra-tumoral heterogeneity. This heterogeneity complicates the diagnosis and treatment of cancer patients, because CSCs can give rise to aggressive clones that are metastatic and insensitive to multiple drugs, or to dormant tumor cells that are difficult to detect.

TGF-β Signaling and Resistance to Cancer Therapy.

The transforming growth factor β (TGF-β) pathway, which is well studied for its ability to inhibit cell proliferation in early stages of tumorigenesis while promoting epithelial-mesenchymal transition and invasion in advanced cancer, is considered to act as a double-edged sword in cancer. Multiple inhibitors have been developed to target TGF-β signaling, but results from clinical trials were inconsistent, suggesting that the functions of TGF-β in human cancers are not yet fully explored. Multiple drug resistance is a major challenge in cancer therapy; emerging evidence indicates that TGF-β signaling may be a key factor in cancer resistance to chemotherapy, targeted therapy and immunotherapy.

Capturing the grouping and compactness of high-level semantic feature for saliency detection.

Saliency detection is an important and challenging research topic due to the variety and complexity of the background and saliency regions. In this paper, we present a novel unsupervised saliency detection approach by exploiting the grouping and compactness characteristics of the high-level semantic features. First, for the high-level semantic feature, the elastic net based hypergraph model is adopted to discover the group structure relationships of salient regional points, and the calculation of the spatial distribution is constructed to detect the compactness of the saliency regions.

Maf1 suppression of ATF5-dependent mitochondrial unfolded protein response contributes to rapamycin-induced radio-sensitivity in lung cancer cell line A549.

mTOR is well known to promote tumor growth but its roles in enhancing chemotherapy and radiotherapy have not been well studied. mTOR inhibition by rapamycin can sensitize cancer cells to radiotherapy. Here we show that Maf1 is required for rapamycin to increase radio-sensitivity in A549 lung cancer cells.

NANOG Alleviates the Damage of Human Hair Follicle Mesenchymal Stem Cells Caused by H2O2 through Activation of AKT Pathway.

Objective: To explore the protective effect of NANOG against hydrogen peroxide (H2O2) -induced cell damage in the human hair follicle mesenchymal stem cells (hHF-MSCs).

Methods: NANOG was expressed from a lentiviral vector, pLVX-IRES-ZsGreen. NANOG hHF-MSCs and vector hHF-MSCs were treated with 400 μmol/L hydrogen peroxide (H2O2) for 2 h, the cell survival rate, cell morphology, ROS production, apoptosis and expression of AKT, ERK, and p21 were determined and compared.

Atypical function of a centrosomal module in WNT signalling drives contextual cancer cell motility.

Centrosomes control cell motility, polarity and migration that is thought to be mediated by their microtubule-organizing capacity. Here we demonstrate that WNT signalling drives a distinct form of non-directional cell motility that requires a key centrosome module, but not microtubules or centrosomes. Upon exosome mobilization of PCP-proteins, we show that DVL2 orchestrates recruitment of a CEP192-PLK4/AURKB complex to the cell cortex where PLK4/AURKB act redundantly to drive protrusive activity and cell motility.

A feed forward loop enforces YAP/TAZ signaling during tumorigenesis.

In most solid tumors, the Hippo pathway is inactivated through poorly understood mechanisms that result in the activation of the transcriptional regulators, YAP and TAZ. Here, we identify NUAK2 as a YAP/TAZ activator that directly inhibits LATS-mediated phosphorylation of YAP/TAZ and show that NUAK2 induction by YAP/TAZ and AP-1 is required for robust YAP/TAZ signaling. Pharmacological inhibition or loss of NUAK2 reduces the growth of cultured cancer cells and mammary tumors in mice.

[Subhabitat selection and differences of diet composition for Acanthogobius ommaturus in the Dongtan wetland of the Yangtze estuary, China].

We examined the temporal and spatial variation in the abundance and diet composition of Acanthogobius ommaturus at three subhabitats (mudflat, salt marsh, and creek) of the Dongtan wetland of Yangtze Estuary with monthly field samplings from July 2015 to June 2016. The results showed that the samples of A. ommaturus were mainly composed of young individuals in the period of June-November, whereas no fish was collected during the other months.

Nutritional Composition and Bioactive Constituents of Artificial Culture of Ophiocordyceps longissima (Ascomycetes).

In this study, the compositions of Ophiocordyceps longissima mycelia, synnemata, and fruiting bodies were first analyzed in order to clarify its chemical basis for development as a health food or medicine. We found that the contents of crude protein, polysaccharides, and macroelements were highest in mycelia, whereas effective components, including mannitol, ergosterol, adenosine, inosine, Zn, and Se, were lowest in mycelia. Polysaccharide, mannitol, and ergosterol levels in synnemata (2.
