In this study, we determined the number of peripheral blood circulating tumor cells (CTCs) pre- and post-NK in patients with stage Ⅳ non- small cell lung cancer (NSCLC) as a reference for understanding the relevance of any changes to the efficacy of NK cells therapy. The patients were given one to three courses of immunotherapy.CTC numbers and CTC-related gene expression were measured in the peripheral blood of 31 patients with stage Ⅳ NSCLC at 1day before and 7 and 30 d after NK cells therapy using magnetic activated cell sorting (MACS) and fluorescence activated cell sorting (FACS) combined with real-time quantitative PCR (RT-qPCR)...

Lung cancer is one of the most common causes of cancer-related death in the world. The large number of lung cancer cases is non-small cell lung cancer (NSCLC), which approximately accounting for 75% of lung cancer. Over the past years, our comprehensive knowledge about the molecular biology of NSCLC has been rapidly enriching, which has promoted the discovery of driver genes in NSCLC and directed FDA-approved targeted therapies. Of course, the targeted therapies based on driver genes provide a more exact option for advanced non-small cell lung cancer, improving the survival rate of patients...

Near-infrared fluorescence (NIRF) dyes have recently emerged as promising tools for non-invasive imaging of different types of cancers. Here, we explored the potential utility of a NIRF DZ-1 dye, with dual imaging and tumour targeting functions, in hepatocellular carcinoma (HCC). We showed the preferential uptake of DZ-1 by HCC cells in vitro and in derived subcutaneous/orthotopic tumour xenografts, accompanied by a minimal effect on normal cells. DZ-1 simplified tumour growth profiling as well, since we were able to correlate NIRF signals with tumour volume and/or tumour-emitting luminescence in mice...

BACKGROUND: Echinococcosis is a serious, zoonotic, parasitic disease with worldwide distribution. According to a epidemiological survey in 2012 in China, there are 20,000 infected patients and more than 50 million people at the risk. As the dog is the main, definitive host, the Government of China encourages monthly praziquantel treatment of every dog. However, this is difficult to achieve in geographically challenging areas, such as the Tibetan plateau, where there are also many dogs without owners...

BACKGROUND: Pancreatoduodenectomy is a surgical procedure used to treat diseases of the pancreatic head and, less often, the duodenum. The most common disease treated is cancer, but pancreatoduodenectomy is also used for people with traumatic lesions and chronic pancreatitis. Following pancreatoduodenectomy, the pancreatic stump must be connected with the small bowel where pancreatic juice can play its role in food digestion. Pancreatojejunostomy (PJ) and pancreatogastrostomy (PG) are surgical procedures commonly used to reconstruct the pancreatic stump after pancreatoduodenectomy...

Inhibition of the bromodomain of the transcriptional regulator CBP/P300 is an especially interesting new therapeutic approach in oncology. We recently disclosed in vivo chemical tool 1 (GNE-272) for the bromodomain of CBP that was moderately potent and selective over BRD4(1). In pursuit of a more potent and selective CBP inhibitor we used structure-based design. Constraining the aniline of 1 into a tetrahydroquinoline motif maintained potency and increased selectivity 2-fold. Structure-activity relationship studies coupled with further structure-based design targeting the LPF shelf, BC loop and KAc regions allowed us to significantly increase potency and selectivity, resulting in the identification of non-CNS penetrant 19 (GNE-781; TR-FRET IC50 = 0...

This paper describes a novel method for displaying data obtained by three-dimensional medical imaging, by which the position and orientation of a freely movable screen are optically tracked and used in real time to select the current slice from the data set for presentation. With this method, which we call a "freely moving in-situ medical image", the screen and imaged data are registered to a common coordinate system in space external to the user, at adjustable scale, and are available for free exploration...

College students who perceive their parents to hold permissive views about their alcohol use engage in heavier drinking. However, few studies have assessed perceived parental permissibility of alcohol use (PPP) longitudinally across the later college years, and few have assessed variation in changes in PPP and whether or not these changes differentially predict drinking. This study assessed whether PPP changed across college and used two approaches to determine whether PPP predicted binge drinking frequency and peak drinking...

The nitrogen-vacancy (NV) centers in diamond are among the most thoroughly investigated defects in the solid state of matter; however, our understanding of their properties upon far-UV excitation of the host matrix is limited. The knowledge is crucial for the identification of NV as the carrier of extended red emission (ERE) bands detected in a wide range of astrophysical environments. Here, we report a study on the photoluminescence spectra of NV-containing nanodiamonds excited with synchrotron radiation over the wavelength range of 125 - 350 nm...

Traditionally, a reduction in floating behavior or immobility in the Porsolt forced swim test (FST) is employed as a predictor of antidepressant efficacy. However, over the past several years, our studies of alcohol withdrawal-induced negative affect consistently indicate the coincidence of increased anxiety-related behaviors on various behavioral tests with reduced immobility in the FST. Further, this behavioral profile correlates with increased mGlu5 protein expression within limbic brain regions. As the role for mGlu5 in anxiety is well established, we hypothesized that the reduced immobility exhibited by alcohol-withdrawn mice when tested in the FST might reflect anxiety, possibly a hyper-reactivity to the acute swim stressor...

Long noncoding RNAs (lncRNAs) have important roles in various biological processes. Our previous work has revealed that dedifferentiation of retinal pigment epithelium (RPE) cells contributes to the pathology of age-related macular degeneration (AMD). Herein, we show roles of lncRNAs in RPE differentiation. We used microarray to identify lncRNA expression profiles in human induced pluripotent stem cells (hiPSCs) and hiPSC-derived RPE cells. A total of 217 differentially expressed lncRNAs along with the differentiation were initially identified, among which 13 lncRNAs showed a consistent fold change of over 2...

BACKGROUND: Alzheimer disease (AD) is a very challenging experience for all those affected. Unfortunately, detection of Alzheimer disease in its early stages when clinical treatments may be most effective is challenging, as the clinical evaluations are time-consuming and costly. Recent studies have demonstrated a close relationship between cognitive function and everyday behavior, an avenue of research that holds great promise for the early detection of cognitive decline. One area of behavior that changes with cognitive decline is language use...

Interfacing light-sensitive semiconductors with graphene can afford high-gain phototransistors by the multiplication effect of carriers in the semiconductor layer. So far, most devices consist of one semiconductor light-absorbing layer, where the lack of internal built-in field can strongly reduce the quantum efficiency and bandwidth. Here, we demonstrate much improved graphene phototransistor performances using an epitaxial organic heterostructure composed of perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) and pentacene as the light-absorbing layer...

RANKL/RANK/OPG axis is important in bone metabolism regulation, and becomes a popular research area in bone diseases. RANKL is a critical part of RANKL/RANK/OPG axis, and widely required in bone metabolism research. However, the yield of recombinant soluble human RANKL (hRANKL) in Escherichia coli is much lower than mouse RANKL (mRANKL). In this study, by adjusting and stabilizing the pH value of LB medium at 7.5, lowering the inducing temperature to 16 ℃ and optimizing the lysis program, the yield of soluble hRANKL increased by approximately 5 to 12-fold over the non-adjusted group...

Rapidly proliferating tumors are exposed to a hypoxic microenvironment due to their density, high metabolic consumption, and interruptions in blood flow due to immature angiogenesis. Cellular responses to hypoxia promote highly malignant and metastatic behavior, as well as a chemotherapy-resistant state. In order to better understand the complex relationships between hypoxic adaptations and cancer progression, we studied the dynamic proteome responses of glioblastoma cells exposed to hypoxia via an innovative approach: quantification of newly synthesized proteins using heavy stable-isotope arginine labeling combined with accurate assessment of cell replication by quantification of the light/heavy arginine ratio of peptides in histone H4...

We present a heuristic control theory model that describes smoking under restricted and unrestricted access to cigarettes. The model is based on the allostasis theory and uses a formal representation of a multiscale opponent process. The model simulates smoking behavior of an individual and produces both short-term ("loading up" after not smoking for a while) and long-term smoking patterns (e.g., gradual transition from a few cigarettes to one pack a day). By introducing a formal representation of withdrawal- and craving-like processes, the model produces gradual increases over time in withdrawal- and craving-like signals associated with abstinence and shows that after 3 months of abstinence, craving disappears...

Aflatoxins (AFs) are a class of carcinogens, associated with liver cancers, that exist in foodstuffs. There are extremely low maximum limits of AFs in foodstuffs (0.025-20 μg·kg(-1)). Quick and sensitive detection of such low concentration of AFs in foodstuffs is dominated by the efficiency and selectivity of the AF enrichment process, which is extremely challenging although substantial efforts have been made in recent decades. Here we design and synthesize a multilayer nanoarchitecture composed of a broad-spectrum aflatoxin monoclonal antibody shell, chitosan middle layer, and magnetic bead core (denoted AF-mAb/CTS/Fe3O4)...
