New data are presented on the distribution and frequency of self-sterility (SS) - predominantly pre-zygotic self-incompatibility (SI) systems in flowering plants hypothesis is tested that families with self-sterile taxa have higher net diversification rates (DRs) than those exclusively self-compatible using both absolute relative rate tests.Three major forms SI (where pollen rejected at stigmatic, stylar or ovarian interface) found to occur oldest plants, times divergence >100 million years...

Recent progress in the analysis of whole genome sequencing data has resulted emergence paleogenomics, a field devoted to reconstruction ancestral genomes. Ancestral karyotype reconstructions have been used primarily illustrate dynamic nature evolution. In this paper, we demonstrate how they can also be study individual gene families by examining evolutionary history relaxin hormones (RLN/INSL) and family peptide receptors (RXFP). Relaxin are members insulin superfamily, implicated regulation...

Background: Psoriasis is a chronic inflammatory condition that predominantly affects the skin and associated with extracutaneous disorders, such as bowel disease arthritis. Changes in gut immunology microbiota are important drivers of proinflammatory disorders could play role pathogenesis psoriasis. Therefore, we explored whether psoriasis Central Asian cohort alterations select immunological markers and/or gut. Methods: We undertook case-control study stool samples collected from...

Conservation aquaculture provides a means for promoting environmental stewardship, useful both in the context of restoring native species and limiting production invasive species. Aquaculture lampreys is relatively recent endeavor aimed primarily at producing animals to support restoration declining populations. However, Laurentian Great Lakes, where sea lamprey Petromyzon marinus are invasive, ability acquire reliable source certain life stages would be significant benefit those controlling...

This study was designed to compare the work flow efficiency of manual measurements 5 fetal parameters with a novel technique that automatically measures these from 2-dimensional sonograms. prospective included 200 singleton pregnancies between 15 and 40 weeks' gestation. Patients were randomly allocated either (n = 100) or automatic biometry. The measurement performed using commercially available software application. A digital video recorder captured all on-screen activity associated...

Routine ultrasound exam in the second and third trimesters of pregnancy involves manually measuring fetal head brain structures 2-D scans. The procedure requires a sonographer to find standardized visualization planes with probe place measurement calipers on interest. process is tedious, time consuming, introduces user variability into measurements. This paper proposes an automatic (AFHB) system for automatically anatomical from 3-D volumes. searches volume hierarchy resolutions by focusing...

There is ample theoretical and experimental evidence that angiosperms harbouring self-incompatibility (SI) systems are likely to respond global changes in unique ways relative taxa with other mating systems. In this paper, we present an updated database on the prevalence of SI across examine relationship between presence latitude, biomes, life-history traits management conditions evaluate potential vulnerability climate change habitat disturbance.

3D ultrasound imaging has been increasingly used in clinics for fetal examination. However, manually searching the optimal view of face volumes is cumbersome and time-consuming even expert physicians sonographers. In this paper we propose a learning-based approach which combines both 2D information automatic fast detection from volumes. Our applies new technique - constrained marginal space learning mesh detection, boosting-based profile to refine pose. To enhance rendering face, an carving...

In this paper, we present a novel probabilistic framework for automatic follicle quantification in 3D ultrasound data. The proposed robustly estimates size and location of each individual ovarian by fusing the information from both global local context. Follicle candidates at detected locations are then segmented database guided segmentation method. To efficiently search hypothesis high dimensional space multiple object detection, clustered marginal learning approach is introduced. Extensive...

Abstract Schistosoma mansoni ( Sm ) infection has been linked with an increased risk of HIV acquisition in women. Therefore, defining the mechanism(s) by which alters susceptibility might lead to new prevention strategies. Here, we analyze impact standard therapy HIV-uninfected + Ugandan adult women on genital and mucosal systemic immunology. Schistosomiasis treatment induces a profound reduction entry into cervical blood CD4+ T cells that is sustained for up two months, despite transient...

Abstract Sea lamprey undergo programmed genome rearrangement (PGR) in which ∼20% of the is jettisoned from somatic cells during embryogenesis. Although role PGR embryonic development has been studied, germline-specific region (GSR) gonad unknown. We analysed RNA-sequence data 28 sea gonads sampled across life-history stages, generated a genome-guided de novo superTranscriptome with annotations, and identified genes (GSGs). Overall, we 638 GSGs that are enriched for reproductive processes...

Background and Aims A vast quantity of empirical evidence suggests that insufficient or quality pollen may lead to a reduction in fruit set, particular for self-incompatible species.This study uses an integrative approach combines field research with marker gene analysis understand the factors affecting reproductive success widely distributed species, Prunus virginiana (Rosaceae).† Methods Twelve patches P. within three populations differed degree disturbance were examined.Two sites small...

In women, most HIV infections are acquired through penile-vaginal sex. Inflammation in the female genital tract (FGT) increases risk of acquisition and transmission, likely recruitment target cells disruption epithelial barrier integrity. Although sex may have important immune effects, impact receptive on correlates susceptibility is not well described.STI-free heterosexual couples were recruited to Sex, Couples Science (SECS) Study, with serial collection cervical secretions (CVS),...

The giant kangaroo rat, Dipodomys ingens (Heteromyidae), is an endangered rodent that inhabits approximately 3% of its estimated historic range. Its current distribution centered in two geographic areas, situated about 150 km apart, south‐central California. We sequenced a 293 base‐pair fragment at the 5' end control region 95 rats from nine localities to examine genetic structure extant populations. determine mutations this section follow negative binominal distribution, rather than...

The use of 3-D ultrasound data has several advantages over 2-D for fetal biometric measurements, such as considerable decrease in the examination time, possibility post-exam processing by experts and ability to produce views anatomies orientations that cannot be seen common exams. However, search standardized planes precise localization volumes are hard time consuming processes even expert physicians sonographers. relative low resolution volumes, small size fetus inter-volume position,...
