We previously established the genetic locus of the rolled-leaf mutant, γ-rl, to chromosome 3. In this study, we performed a comparative genomic hybridization (CGH) analysis to identify the genes responsible for the γ-rl mutant phenotype. This was combined with RNA transcriptome sequencing (RNA-seq) to analyze differences in the mRNA expression in seeds 12 h after germination. Using the reference genome of the "indica type" rice from GenBank, we created a chip with 386,000 high density DNA probes designed to target chromosome 3...

Optical coherence tomography (OCT) is increasingly used to obtain objective measurements of the retinal nerve fiber layer (RNFL), optic nerve head, and macula for assessing glaucoma progression. Although OCT has been adopted widely in clinical practice, uncertainty remains concerning its optimal role. Questions include: What is the best structure to measure? What quantity of change is significant? Are structural changes relevant to the patient? How are longitudinal measurements affected by aging? How can changes resulting from aging be differentiated from true progression? How best should OCT be used alongside visual fields, and how often should OCT be performed? Recent studies have addressed some of these questions...

The term "subjective circadian amplitude" refers to the range or the distinctness of diurnal variations of arousal, that is, the awareness (or lack thereof) of difference between hyper- and hypo-activation phases, the ability to volitionally modulate one's own psychophysiological state, the strength of morning-evening preferences and flexibility of the rhythm or perceived stability of the circadian phase. The complexity of this construct is the source of difficulties in research and measurement. The psychometric features of distinctness subscales of the Chronotype Questionnaire and the Caen Chronotype Questionnaire are not satisfactory...

Fame and eminence, as traditionally measured, limit the definition of impact to the publication world. We add two types of impact to the traditional measures of fame and eminence. Many of the traditional measures of fame or eminence are based on social-network connections, whereby individuals appoint other people to positions of eminence. Editorial boards are one specific example. Eminence is also limited to number of publications, for example, with little regard for the impact of those publications at the societal level...

Background: Species living at high altitude are subject to strong selective pressures due to inhospitable environments (e.g., hypoxia, low temperature, high solar radiation, and lack of biological production), making these species valuable models for comparative analyses of local adaptation. Studies that examined high-altitude adaptation identified a vast array of rapidly evolving genes that characterize the dramatic phenotypic changes in high-altitude animals. However, how high-altitude environment shapes gene expression programs remains largely unknown...

BACKGROUND: In our contemporary world, while part of the fibers used in the paper industry is obtained from primary fibers such as wood and agricultural plants, the rest is obtained from secondary fibers from waste papers. To manufacture paper with high optical quality from fibers of recycled waste papers, these papers require deinking and bleaching of fibers at desired levels. High efficiency in removal of ink from paper mass during recycling, and hence deinkability, are especially crucial for the optical and printability quality of the ultimate manufactured paper...

Background: Dysfunctional regulation at immune checkpoints may lead to escape of the tumor cells and gives a scope to set in the unresolved Breast cancer (BC). The major anti-tumor retort is cell-mediated response which involves T lymphocytes. CTLA-4 (Cytotoxic T lymphocyte associated protein-4) with immune suppressive function and tolerance is associated with various autoimmune diseases and cancers including BC. The present study deals with CTLA-4 gene selected polymorphisms (rs11571317 C/T and rs3087243G/A) to explore their relation with breast cancer susceptibility and progression in BC patients...

There is little known about illness perception in patients with skin tumors. We conducted this study to investigate Iranian patients' understanding of skin tumors, and to evaluate their sun-protective behavior changes after treatment of skin cancer. Patients with a skin biopsy of basal cell carcinoma were asked to complete questionnaires. A total of 110 patients were enrolled in the study. Patients were mostly referred to our tumor clinic from rural areas. At the skin cancer perception investigation, 63% of patients did not consider their disease as a long-lasting situation...
