Thus, co-localization

analysis can be performed using only a single detection channel. Furthermore, the proteins were used to tag the RNA-binding protein AtGRP7 (Arabidopsis thaliana glycine-rich RNA-binding www.selleckchem.com/products/gm6001.html protein 7) in transgenic Arabidopsis plants. Because the new reversibly photoswitchable fluorescent proteins show an increase in signal strength during each photoactivation cycle, we were able to generate a large number of scans of the same region and reconstruct 3-D images of AtGRP7 expression in the root tip. Upon photoactivation of the AtGRP7:rsFastLIME-s fusion protein in a defined region of a transgenic Arabidopsis root, spreading of the fluorescence signal into adjacent regions was observed, indicating that movement from cell to cell can be monitored. Our results demonstrate that rsFastLIME-s, bsDRONPA-s, and PADRON C-s are versatile fluorescent markers in plants. Furthermore, the proteins also show strong fluorescence in mammalian cells including COS-7 and HeLa cells.”
“Pediatric facial fractures account for only 5% of all facial fractures, with even a much lower incidence in children younger than 5 years (1%-1.5%). The evolution of principles in the management PLX3397 solubility dmso of pediatric facial fractures and the differences in management between adult and

pediatric patients have been well documented in the literature. Pediatric facial fracture selleck chemical management presents unique challenges because

it might affect growth in the area specific to the trauma segment. Children are, in several ways, at a regenerative advantage: greater osteogenic potential, faster healing rate, primary dentition that is thereby temporary, and the capacity for significant dental compensation. Perhaps because of this, complications such as infection, malunion, nonunion, and postinjury malocclusion are relatively rare compared with the adult population. In this article, we will focus on different approaches to complications that arise after pediatric fracture management.”
“The ability to impute mental states to others, or Theory of Mind (ToM), has been the subject of hundreds of neuroimaging studies. Although reviews and theta-analyses-of these studies have concluded that ToM recruits a coherent brain network, mounting evidence suggests that this network is an abstraction based on pooling data from numerous studies, most of which use different behavioral tasks to investigate ToM. Problematically, this means that no single behavioral task can be used to reliably measure ToM Network function as currently conceived. To make ToM Network function scientifically tractable, we need standardized tasks capable of reliably measuring specific aspects of its functioning. Here, our goal is to validate the Why/How Task for this purpose.

Some well characterized biochemical pathways, such as those associated with von Hippel-Lindau disease, are aberrantly regulated in RCC and are associated with histological subtype, but the understanding of these pathways contributes little to the clinical management of patients with RCC. Gene expression and sequencing studies have increased our understanding of the genetic basis of the disease but have failed to establish any unified classification to improve molecular stratification or to predict which patients are FK228 likely to relapse or respond to targeted therapy. Instead, they have served to highlight that

RCC is heterogeneous at histological, morphological, and molecular levels, and that novel approaches are required to resolve the complexity of RCC prognostication and prediction of treatment response.”
“To investigate whether the reported fitness cost of virulence at the AvrLm4 locus in Leptosphaeria maculans is common to other loci, near-isogenic (NI) isolates differing at AvrLm1 locus were produced in vitro. Fitness of virulent (avrLm1)

or avirulent (AvrLm1) isolates on Brassica napus without the corresponding R (resistance) gene Rlm1 was investigated in controlled environment (CE) and field experiments. Results indicate that there is a measurable fitness cost for avrLm1 compared to AvrLm1 isolates in terms of number of lesions, size of lesions, distance grown through leaf tissue towards the petiole in CE experiments and systemic growth from leaf lesions to stems in field experiments. There were differences in fitness cost between the AvrLm1 and AvrLm4 loci. There was a cultivar GSK3326595 cost effect Ralimetinib in vivo on fitness cost of virulence at the AvrLm1 locus but not at the AvrLm4 locus. In CE experiments, the optimal temperature for leaf infection was greater for AvrLm4 isolates than for AvrLm1 isolates. Field experiment results suggest that on the same host AvrLm4 isolates

are more fit than AvrLm1 isolates in warmer seasons. The fitness cost at the AvrLm4 locus was generally greater than at the AvrLm1 locus, suggesting that the corresponding R gene Rlm4 may be more suitable than Rlm1 for redeployment in commercial cultivars after an interval of a few years.”
“Humans have the capacity to evaluate the success of cognitive processes, known as metacognition. Convergent evidence supports a role for anterior prefrontal cortex in metacognitive judgements of perceptual processes. However, it is unknown whether metacognition is a global phenomenon, with anterior prefrontal cortex supporting metacognition across domains, or whether it relies on domain-specific neural substrates. To address this question, we measured metacognitive accuracy in patients with lesions to anterior prefrontal cortex (n = 7) in two distinct domains, perception and memory, by assessing the correspondence between objective performance and subjective ratings of performance.

The in vitro suppressive properties of several polyphenols were first tested and compared for dendritic cells (DCs) production of inflammatory cytokines. A combination of the polyphenols, quercetin and piperine, were then encapsulated into reconstituted oil bodies

(OBs) in order to increase their stability. Our results showed that administration of low dose reconstituted polyphenol OBs inhibited LPS-mediated inflammatory cytokine secretion, including IL-6, IL-23, and IL-12, while increasing IL-10 and IL-1R alpha production. Mice treated with the polyphenol-containing reconstituted OBs (ROBs) were partially protected from dextran sodium sulfate (DSS)-induced colitis and associated weight loss, while selleck inhibitor mortality and inflammatory scores revealed an overall anti-inflammatory effect that was likely mediated by impaired DC immune responses. Our study indicates that the administration of reconstituted quercetin and piperine-containing OBs may represent an effective and potent anti-inflammatory strategy to treat acute intestinal inflammation.”
“Nitrogen (N)-doped ZnO thin films have been deposited on Si (100) substrates by pulsed laser deposition under different N(2) pressures. The optical

and magnetic properties of N-doped ZnO films have been studied with photoluminescence, Raman spectroscopy, and vibrating sample magnetometer. Photoluminescence and Raman studies reveal that Epigenetics inhibitor N(2) pressure affected the defects of N-doped ZnO films. Under 10 Pa N(2) pressure, N substitutes O and forms N(O) acceptor. Zn interstitials are main compensating donors. Under higher N(2) pressures, N not only substitutes O but also forms N(2)O molecules in N-doped ZnO films. Zn antisizes are compensating donors. In additional, Zn vacancies are formed and the concentration increases with increasing N(2) pressure. Magnetic properties of these films show that there are two distinct ferromagnetic mechanisms: the origin of ferromagnetism in the ZnO:N-10 Pa film is Zn

interstitial, while Zn vacancy leads to ferromagnetism in the ZnO:N-50 Pa film. (c) 2010 American Institute of Selleckchem JPH203 Physics. [doi:10.1063/1.3468690]“
“The first synthesis of polyamido-saccharides (PASs) from a galactose (gal)-derived beta-lactam sugar monomer is reported. The polymers are prepared using a controlled anionic ring-opening polymerization and characterized by NMR, optical rotation, IR, and GPC. Galactose-derived PASs display high solubility in aqueous solutions and are non-cytotoxic to HepG2, CHO, and He La cell lines. To evaluate whether gal-derived PASs are recognized by the gal-specific lectin present on human hepatocytes, cellular uptake of rhodamine-labeled polymers is assessed using flow cytometry and fluorescence microscopy. On the basis of these results, the polymers are taken into cells via endocytosis that is not dependent on the gal-specific receptor on hepatocytes.

Low

response to clopidogrel has been associated with increased risk of stent thrombosis and ischemic events, particularly in the context of stable heart disease treated PCI32765 by percutaneous coronary intervention.\n\nObjective: To stratify medium-term prognosis of an acute coronary syndrome (ACS) population by platelet aggregation.\n\nMethods: We performed a prospective longitudinal study of 70 patients admitted for an ACS between May and August 2009. Platelet function was assessed by ADP-induced platelet aggregation using a commercially available kit (Multiplate (R) analyzer) at discharge. The primary endpoint was a combined outcome of mortality, non-fatal myocardial infarction, or unstable angina, with a median follow-up of 136.0 (79.0-188.0) days.\n\nResults: The median value of platelet aggregation was 16.0 U (11.0-22.5 U) with a maximum of 41.0 U and a minimum of 4.0

U (normal value according to the manufacturer: 53-122 U). After ROC curve analysis with respect to the combined endpoint (AUC 0.72), we concluded that a value of 18.5 U conferred a sensitivity of 75.0% and a specificity of 68% to that result. We therefore created CA4P cell line two groups based on that level: group A – platelet aggregation <18.5 U, n = 44; and group B – platelet aggregation >= 18.5 U, n = 26. The groups were similar with respect to demographic data (age 60.5 [49.0-65.0] vs. 62.0 [49.0-65.0] years, p = 0.21), previous cardiovascular history, and admission diagnosis. There were no associations between left ventricular ejection fraction, GRACE risk score, or length of hospital stay and platelet aggregation. The groups were also similar with respect to antiplatelet, anticoagulant, proton pump inhibitor (63.6 vs. 46.2%, p = MLN4924 price 0.15) and statin therapy. The variability in platelets and hemoglobin was also similar between groups. Combined event-free survival was higher in group A (96.0 vs. 76.7%, log-rank p<0.01). Platelet aggregation higher than 18.5 U was an independent predictor of the combined event (HR 6.75, 95% CI 1.38-32.90, p = 0.02).\n\nConclusion: In our ACS population platelet aggregation

at discharge was a predictor of medium-term prognosis. (C) 2011 Sociedade Portuguesa de Cardiologia. Published by Elsevier Espana, S.L. All rights reserved.”
“Ayurveda traces its origins to contributions of mythological and real physicians that lived millennia earlier. In many respects, Western medicine also had similar origins and beliefs, however, the introduction of anatomical dissection and progressive application of scientific evidence based practices have resulted in divergent paths taken by these systems. We examined the lives, careers, and contributions made by nine ancient Indian physicians. Ancient texts, translations of these texts, books, and biographical works were consulted to obtain relevant information, both for Indian traditional medicine as well as for Western medicine.

\n\nResults: Due to an acute bleeding situation in 143 patients, 7.9 +/- 5.8 units of packed red blood cells, 9.5 +/- 6.1units of fresh frozen plasma, 1740 +/- 1860 IU PPSB (Prothrombin-Proconvertin-Stuart Factor-Antihemophilic Factor B), 5.6 +/- 4 g fibrinogen, and 7.9 +/- 7.6 units of platelets were administered. A re-thoracotomy was necessary, despite maximal procoagulant therapy, in 55% of patients. The in-hospital mortality was 36% (51/2453 = 2%). Thrombotic complications occurred with a frequency ALK activation of 16% (mesenteric infarction, n = 9; stroke/transient ischemic attack, n = 3; myocardial infarction, n = 3; other, n = 8).\n\nConclusion: The proof of direct causality of the events in relation to the

administration of FVIIa is difficult because the temporal and therapeutic relationships with concomitant vasoconstrictive and procoagulant therapies were not obvious. However,

there remains a suspicion that a higher rate of mesenteric infarctions may be provoked by the administration of FVIIa.”
“OBJECTIVE: A number of researchers have suggested the use of sodium hyaluronate carboxymethyl cellulose (HA-CMC) membrane for preventing postoperative adhesion. This study evaluated the anti-adhesive effect and safety of a newly developed HA-CMC solution in thyroidectomy.\n\nMETHODS: Seventy-four patients who underwent thyroidectomy AEB071 were prospectively randomized. In the study group of 38 patients, 5 mL HA-CMC solution was applied to the operative field after thyroidectomy. The subjects were asked about adhesive symptoms using a four-item questionnaire at 2 weeks, 2 months and 6 months after surgery. In addition, three items on the appearance of neck wrinkles and scars were evaluated by a physician. Each item was scored BMS345541 from 0 to 10.\n\nRESULTS: The mean ( standard deviation) total adhesion score at each visit was 15.22 +/- 8.99, 10.42 +/- 8.41, and 7.24 +/- 5.83 for the control group and 19.29 +/-

9.71, 9.46 +/- 5.71, and 6.03 +/- 4.32 for the study group. Total adhesion scores for both groups decreased with time (p<0.001), but no significant differences were noted between the two groups (p>0.066). There were no complications related to the HA-CMC solution.\n\nCONCLUSION: The HA-CMC solution did not decrease subjective or objective postoperative adhesion in patients undergoing thyroid surgery, although it was biologically safe.

“Background: Optimal dosage for growth hormone (GH) therapy in short, prepubertal children born small for gestational age (SGA) is controversial. Methods: SGA OPTIMIS (NCT00249821) is a multicenter, open-label, parallel-group, pilot study of short children born SGA who had received recombinant human GH (r-hGH) (57 mu g/kg/day) for 3 years. Children were randomized 1: 1 to receive either 57 or 35 mu g/kg/day r-hGH during year 4. The primary endpoint was height gain during year 4.

asahii isolates were only available after

the patient died. In vitro antifungal susceptibility tests showed high caspofungin and amphotericin B minimal inhibitory concentrations (MICs) value for this Trichosporon strain (MICs, 16 mu g/ml, and > 32 mu g/ml, respectively). Fluconazole, itraconazole, and voriconazole exhibited low MICs in vitro (MICs, GDC973 4 mu g/ml, 0.5 mu g/ml, and <= 0.015 mu g/ml, respectively). Our experience strongly suggest that identification and antifungal susceptibility testing for T. asahii in neutropenic patients who may develop signs of infection in the presence of caspofungin as well as broadspectrum antibiotics treatment should not be overlooked.”
“American Indians/Alaska Natives (AIANs) compose a heterogeneous population that includes geographically distinct tribal communities, many with high

rates of ESRD. Regional features of dialysis care and mortality are unknown in this population. Here, we describe the structure of dialysis care and mortality of adult AIANs who initiated maintenance dialysis during 1995-2008 in different regions of the US. Overall, 13,716 AIANs received dialysis at 2054 facilities. Approximately 10% (n = 197) of these facilities provided care to two-thirds (n = 9011) of AIANs. AIANs from the Southwest and Alaska were concentrated VEGFR inhibitor in relatively few dialysis facilities whereas those in the Eastern US and Pacific Coast were distributed more diffusely. Despite comparably high rates of poverty, diabetes, and cardiovascular disease, annual mortality rates were lower in the Southwest (13.9%) compared with the Southern Plains (23.2%), Alaska (21.2%), Eastern US (20.0%), Northern Plains (20.8%), and Pacific Coast BKM120 chemical structure (22.0%). These regional differences were consistent over time and persisted after adjusting for sociodemographic and clinical variables and area-based poverty. In conclusion, regional differences in the structure of dialysis care and patient mortality exist among AIANs. Southwestern AIANs experience the highest concentration of dialysis care

and the lowest mortality. Our findings suggest that an area-based approach examining the care structure of relatively few dialysis facilities may delineate determinants of these differences and improve the quality of care to many AIAN communities.”
“Taxonomic characterization was performed on the putative N-2-fixing microbiota associated with the coral species Mussismilia hispida, and with its sympatric species Palythoa caribaeorum, P. variabilis, and Zoanthus solanderi, off the coast of Sao Sebastiao (Sao Paulo State, Brazil). The 95 isolates belonged to the Gammaproteobacteria according to the 16S rDNA gene sequences. In order to identify the isolates unambiguously, pyrH gene sequencing was carried out. The majority of the isolates (n = 76) fell within the Vibrio core group, with the highest gene sequence similarity being towards Vibrio harveyi and Vibrio alginolyticus. Nineteen representative isolates belonging to V. harveyi (n = 7), V.

The rats were randomly divided into (i) anesthesia-only as the control group; (ii) laparotomy-only as the open group; and (iii) CO2 pneumoperitoneum-only as the pneumoperitoneum group. To evaluate the gut immune system in a time-dependent manner, each group

was further divided into short- and long-time subgroups. s-IgA levels did not increase in the open group but significantly increased in the pneumoperitoneum group compared with the control group (p smaller than 0.05). In addition, s-IgA levels in the long-time subgroup significantly increased compared with the short-time subgroup of the pneumoperitoneum group (p smaller than 0.05). TLR4 levels steeply IPI-145 cost and gradually increased in the open and pneumoperitoneum groups, respectively. MDA levels in the pneumoperitoneum group increased during the early phase and were significantly higher than those in the open group at 24 h (p smaller than 0.05). This study demonstrated that s-IgA levels in stool increased in the pneumoperitoneum group compared with the open group, PRIMA-1MET manufacturer suggesting that CO2 pneumoperitoneum may cause transitory damage to the intestinal mucosa.”
“Lyme borreliosis is the most important vector-borne disease in the

Northern hemisphere. It is caused by Borrelia burgdorferi sensu lato bacteria transmitted to humans by the bite of hard ticks, Ixodes spp. Although antibiotic treatments are efficient in the early stage of the infection, a significant number of patients develop disseminated manifestations (articular, neurological,

and cutaneous) due to unnoticed or absence of erythema migrans, or to inappropriate treatment. Vaccine could be an efficient approach to decrease Lyme disease incidence. We have developed a proteomic approach based on a one dimensional gel electrophoresis followed by LC-MS/MS strategy to identify new vaccine candidates. We analyzed a disseminating clone and the associated wild-type strain for each major pathogenic Borrelia species: B. burgdorferi sensu stricto, B. garinii, and B. afzelii. We identified specific proteins and common proteins to the disseminating clones of the three main species. In parallel, we used a spectral counting check details strategy to identify upregulated proteins common to the clones. Finally, 40 proteins were found that could potentially be involved in bacterial virulence and of interest in the development of a new vaccine. We selected the three proteins specifically detected in the disseminating clones of the three Borrelia species and checked by RT-PCR whether they are expressed in mouse skin upon B. burgdorferi ss inoculation. Interestingly, BB0566 appears as a potential vaccine candidate. All MS data have been deposited in the ProteomeXchange with identifier PXD000876 ().”

The development of alendronate (ALN)-coated magnetite thus serves as a rapid initial screen for the ability of targeting ligands to enhance nanoparticle-antiretroviral drug biodistribution, underscoring the value of decorated magnetite particles as a theranostic IACS-10759 order tool for improved drug delivery.”
“In the DNA damage response, c-Abl tyrosine kinase is transiently accumulated in the nucleus and induces apoptosis; however, little is known about the mechanism underlying apoptosis induction via nuclear c-Abl. Here we demonstrate that the

expression of human pituitary homeobox 1 (Pitx1) transcription factor is increased after DNA damage. Notably, c-Abl controls augmentation of Pitx1 at the post-transcriptional level. Overexpression of c-Abl induces tyrosine phosphorylation of Pitx1, either directly or indirectly. We also show that, upon exposure to genotoxic stress, overexpression of Pitx1 is associated with marked induction of apoptosis that is independent of p53 status. Importantly, inhibition of c-Abl kinase activity substantially attenuates Pitx1-mediated apoptosis. These findings provide evidence that c-Abl participates in modulating Pitx1 expression in the apoptotic response to DNA damage.”
“In some psychiatric disorders 5-HT2A receptors play an important role. In order to investigate those in vivo there is an increasing

interest in obtaining a metabolically stable, subtype selective and high affinity radioligand for receptor binding studies using positron emission tomography (PET). CX-6258 concentration MCC950 Immunology & Inflammation inhibitor Combining the excellent in vivo properties of [C-11]MDL 100907 for PET imaging of 5-HT2A receptors and the more suitable half-life of fluorine-18, MDL 100907 was radiofluorinated in four steps using 1-(2-bromoethyl)-4-[F-18]fluorobenzene as a secondary labelling precursor. The complex reaction required an overall reaction time of 140 min and [+/-)-[F-18]MDL

100907 was obtained with a specific activity of at least 30 GBq/mu mol (EOS) and an overall radiochemical yield of 1-2%. In order to verify its binding to 5-HT2A receptors, in vitro rat brain autoradiography was conducted showing the typical distribution of 5-HT2A receptors and a very low non-specific binding of about 6% in frontal cortex, using ketanserin or spiperone for blocking. Thus, [F-18]MDL 100907 appears to be a promising new 5-HT2A PET ligand.”
“We varied the surface boundary-contour properties of binocular rivalry (BR) stimuli to measure the rivalry percept as a function of stimulus duration. Experiment 1 compared perception from BR stimuli with monocular boundary contour (MBC) and binocular boundary contour (BBC). We found global dominance is achieved with stimulus duration as short as 30 ms for the MBC rivalry stimuli, whereas it takes more than 150 ms for the BBC rivalry stimuli. This shows that global dominance can occur rapidly in the absence of a corresponding boundary contour in one half-image.

The development of five new reverse transcription real-time quantitative click here PCR (RT-qPCR) assays is described, which allow the detection of all known PepMV genotypes. The performance of the assays was evaluated on Peruvian, European tomato, Ch2 and US1 PepMV genotypes and optimised for both two- and one-step RT-qPCR detection formats. One-step RT-qPCR detected PepMV European tomato genotype particles at least two orders of magnitude more sensitively than ELISA. The method detected as little as one naturally infected seed among 5000 uninfected seeds. The genotype-specificity of the

five assays was compared using PepMV isolates representing all of the different genotypes. The following genotype combinations were all discriminated successfully: European tomato-Peruvian, Ch2, and US1. In addition to its application for diagnostic purposes, the genotype-specificity and the quantitative potential of the method, makes it very useful for epidemiological studies or for studies evaluating Danusertib resistance of plants to virus infection.

“To retrospectively review patients who underwent transjugular and image-guided percutaneous biopsy and compare the relative risk of ascites, thrombocytopenia, and coagulopathy.\n\nFrom August 2001 through February 2006, a total of 238 liver biopsies were performed. The radiologist reviewed

all patient referrals for transjugular biopsy. These patients either underwent transjugular biopsy or were reassigned to percutaneous biopsy (crossover selleck group). Patients referred to percutaneous image-guided liver biopsy underwent this same procedure.

Biopsies were considered successful if a tissue diagnosis could be made from the samples obtained.\n\nA total of 36 transjugular biopsies were performed with 3 total (8.3%) and 1 major (2.8%) complications. A total of 171 percutaneous biopsies were performed with 10 (5.8%) total and 3 (1.8%) major complications. The crossover group showed a total of 4 (12.9%) complications with 1 (3.2%) major complication. Sample adequacy was 91.9% for transjugular and 99.5% for percutaneous biopsy.\n\nBoth transjugular and percutaneous liver biopsy techniques are efficacious and safe. Contraindications such as thrombocytopenia, coagulopathy, and ascites are indicators of greater complications but are not necessarily prevented by transjugular biopsy. Percutaneous biopsy more frequently yields a diagnostic specimen than transjugular biopsy.”
“Virus-induced gene silencing (VIGS) is an effective tool for studying the functions of plant genes, but only a few VIGS vectors available for woody plants were reported so far. Here we present an effective heterologous VIGS system in woody plants based on tobacco rattle virus (TRV) vectors. We first tested whether the TRV-vector can be directly applied to infect woody plant species, such as Vernicia fordii, Populus tomentosa Carr. and Camellia oleifera.

Though AL amyloidosis caused by plasma cell dyscrasia usually responses poorly to chemotherapy, this patient

“YU205, a bacteriolytic enzyme produced by Bacillus subtilis YU-1432 exhibited lytic activity against Porphyromonas gingivalis causing periodontal disease. GS-7977 chemical structure Specific activity and purification yield of YU205 were increased by 522.0 times and 21.9%, respectively by 80% acetone precipitation, followed by DEAE-Sepharose and CM-Sepharose column chromatography. The molecular mass of YU205 was estimated to be 29.0 kDa by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), and N-terminal SRT1720 sequencing identified fifteen amino acid residues, AQSVPYGISQIKAPA. YU205 was stabilized against thermal inactivation at 1 mM of CaCl(2). The essential amino acids for the lytic activity were deduced to be tyrosine, methionine, and serine. YU205 showed at least 23.4 times higher substrate specificity to P gingivalis than other proteolytic enzymes tested. These results suggest that the purified enzyme may have potential for the application to food or dental care products to prevent periodontal diseases.”
“Among the existing hashing methods, the Self-taught hashing (STH) is regarded as

the state-of-the-art work. However, it still suffers the problem of semantic loss, which mainly comes from the fact that the original optimization objective of in-sample data is NP-hard and therefore is compromised into the combination of Laplacian Eigenmaps (LE) and binarization. Obviously, the shape associated with the embedding of LE is

quite dissimilar to that of binary code. As a result, binarization of the LE embedding readily leads to significant semantic loss. To overcome this drawback, we combine the constrained nonnegative sparse coding and the Support Vector Machine (SVM) to propose a new hashing method, Selleckchem PF-562271 called nonnegative sparse coding induced hashing (NSCIH). Here, nonnegative sparse coding is exploited for seeking a better intermediate representation, which can make sure that the binarization can be smoothly conducted. In addition, we build an image copy detection scheme based on the proposed hashing methods. The extensive experiments show that the NSCIH is superior to the state-of-the-art hashing methods. At the same time, this copy detection scheme can be used for performing copy detection over very large image database. (C) 2012 Elsevier B.V. All rights reserved.”
“Deep sequencing has become a popular tool for novel miRNA detection but its data must be viewed carefully as the state of the field is still undeveloped.
