Inkjet printer prediction under complicated printing conditions based on microscopic image features.

A novel technique is introduced to predict the printer model used to produce a given document. Samples containing only a few letters printed under varying conditions (i.e.

Giant tortoise genomes provide insights into longevity and age-related disease.

Giant tortoises are among the longest-lived vertebrate animals and, as such, provide an excellent model to study traits like longevity and age-related diseases. However, genomic and molecular evolutionary information on giant tortoises is scarce. Here, we describe a global analysis of the genomes of Lonesome George-the iconic last member of Chelonoidis abingdonii-and the Aldabra giant tortoise (Aldabrachelys gigantea).

Role of the Fibrinogen Degradation Products and D-Dimer in the Differential Diagnosis of Pulmonary Tuberculosis and Community-Acquired Pneumonia.

Background: Differential diagnosis between pulmonary tuberculosis (TB) and community acquired pneumonia (CAP) is often difficult. Pulmonary TB could induce a systemic hypercoagulable state. The present study aims to investigate whether fibrinogen degradation products (FDP) and D-dimer play a diagnostic role for pulmonary TB.

Hypoxia promotes mitochondrial glutamine metabolism through HIF1α-GDH pathway in human lung cancer cells.

Drug-resistance is common in human lung cancer therapy. Hypoxia remarkably contributes to drug-resistance in lung cancer but the underlying mechanism remains elusive. Here we demonstrate that hypoxia-induced glutamine metabolism is involved in drug resistance in lung cancer cells.

Amplicon Indel Hunter Is a Novel Bioinformatics Tool to Detect Large Somatic Insertion/Deletion Mutations in Amplicon-Based Next-Generation Sequencing Data.

Amplicon-based targeted next-generation sequencing assays are used widely to test for clinically relevant somatic mutations in cancer. However, accurate detection of large insertions and deletions (indels) via these assays remains challenging. Sequencing reads that cover these anomalies are, by definition, different from the reference sequence, and lead to variable performance of alignment algorithms.

Poly-L-Arginine Acts Synergistically with LPS to Promote the Release of IL-6 and IL-8 via p38/ERK Signaling Pathways in NCI-H292 Cells.

Major basic protein (MBP) derived from activated eosinophil can exacerbate atopic asthma induced by lipopolysaccharide (LPS). The pharmacological function of MBP can be mimicked by poly-L-arginine (PLA), however, the potential signaling mechanisms of LPS-PLA-induced release of the inflammatory cytokines interleukin (IL)-6 and IL-8 remain unclear. In the present study, airway epithelia NCI-H292 cell lines were treated with LPS and/or PLA.

Hypoxia-induced autophagy mediates cisplatin resistance in lung cancer cells.

Hypoxia which commonly exists in solid tumors, leads to cancer cells chemoresistance via provoking adaptive responses including autophagy. Therefore, we sought to evaluate the role of autophagy and hypoxia as well as the underlying mechanism in the cisplatin resistance of lung cancer cells. Our study demonstrated that hypoxia significantly protected A549 and SPC-A1 cells from cisplatin-induced cell death in a Hif-1α- and Hif-2α-dependent manner.

Reversed expression of GRIM-1 and GRP78 in human non-small cell lung cancer.

Gene associated with retinoid and interferon-induced mortality 1 (GRIM-1) acts as a tumor growth suppressor via apoptosis induction. However, GRIM-1 expression in human non-small cell lung cancer (NSCLC) and its potential interaction with another apoptosis-associated protein-glucose-regulated protein 78 (GRP78)-are as yet unknown. Using 40 surgical specimens, we showed significantly lower expression of GRIM-1 in NSCLC at both protein and messenger RNA (mRNA) levels compared with that in normal tissues (P < .

Host sex-specific parasites in a functionally dioecious fig: a preference way of adaptation to their hosts.

Host-parasites interaction is a common phenomenon in nature. Diffusive coevolution might maintain stable cooperation in a fig-fig wasps system, in which the exploiter might diversify their genotype, phenotype, or behavior as a result of competition with pollinator, whereas the figs change flower syconia, fruits thickness, and syconia structure. In functionally dioecious Ficus auriculata, male figs and female figs contain two types of florets on separate plant, and share high similarities in outside morphology.

Pollinating fig wasp Ceratosolen solmsi adjusts the offspring sex ratio to other foundresses.

Local mate competition theory predicts that offspring sex ratio in pollinating fig wasps is female-biased when there is only one foundress, and increased foundress density results in increased offspring sex ratio. Information of other foundresses and clutch size have been suggested to be the main proximate explanations for sex ratio adjustment under local mate competition. Our focus was to show the mechanism of sex ratio adjustment in a pollinating fig wasp, Ceratosolen solmsi Mayr, an obligate pollinator of the functionally dioecious fig, Ficus hispida Linn.

Comparison of the genome sequences of "Candidatus Portiera aleyrodidarum" primary endosymbionts of the whitefly Bemisia tabaci B and Q biotypes.

"Candidatus Portiera aleyrodidarum" is the primary endosymbiont of whiteflies. We report two complete genome sequences of this bacterium from the worldwide invasive B and Q biotypes of the whitefly Bemisia tabaci. Differences in the two genome sequences may add insights into the complex differences in the biology of both biotypes.

Genome sequences of the primary endosymbiont "Candidatus Portiera aleyrodidarum" in the whitefly Bemisia tabaci B and Q biotypes.

"Candidatus Portiera aleyrodidarum" is the obligate primary endosymbiotic bacterium of whiteflies, including the sweet potato whitefly Bemisia tabaci, and provides essential nutrients to its host. Here we report two complete genome sequences of this bacterium from the B and Q biotypes of B. tabaci.

Expression and clinical significance of GRIM-19 in lung cancer.

We investigated the expression of gene associated with retinoid-interferon-induced mortality-19 (GRIM-19) in lung cancer, a recently discovered cell death regulatory gene. Over-expression of GRIM-19 potentially suppresses proliferation and promotes tumor cell apoptosis. However, the expression of GRIM-19 in human lung cancer has not yet been thoroughly investigated.

Enrichment of mRNA-like noncoding RNAs in the divergence of Drosophila males.

With the advent of transcriptome data, it has become clear that mRNA-like noncoding RNAs (mlncRNAs) are widespread in eukaryotes. Although their functions are poorly understood, these transcripts may play an important role in development and could thus be involved in determining developmental complexity and phenotypic diversification. However, few studies have assessed their potential roles in the divergence of closely related species.

Gene associated with retinoid-interferon-induced mortality-19 suppresses growth of lung adenocarcinoma tumor in vitro and in vivo.

Lung cancer is currently the leading cause of cancer-related death in the world. Signal transducers and activators of transcription 3 (STAT3) is a major oncogenic transcription factor involved in the development and progression of a number of human tumors including lung denocarcinoma. Gene associated with retinoid-interferon-induced mortality-19 (GRIM-19) is known to functionally interact with STAT3 and inhibit its transcriptional activity.

Evolution of sex-dependent gene expression in three recently diverged species of Drosophila.

Sexual dimorphism in morphological, physiological, and behavioral traits is pervasive in animals, as is the observation of strong sexual dimorphism in genomewide patterns of gene expression in the few species where this has been studied. Studies of transcriptome divergence show that most interspecific transcriptional divergence is highly sex dependent, an observation consistent with the action of sex-dependent natural selection during species divergence. However, few transcriptome evolution studies have been conducted between recently diverged species (<1 MY).

New insights into the phylogeny of fig pollinators using Bayesian analyses.

The interaction between figs and fig pollinators is one of the most species-specific mutualisms. Recently, phylogenies of both partners based on molecular data provided insights into a wide spectrum of co-evolutionary questions. However, for the phylogeny of fig pollinators, there are some discrepancies between different studies and left some relationships unresolved, especially for deep nodes.
