Round ligament varicosities diagnosed as inguinal hernia during pregnancy: A case report and series from two regional hospitals in Japan.

Round ligament varicosities (RLV) are not well-known and they are usually caused by pregnancy. Although the groin swelling of RLV mimics an inguinal hernia, it is difficult to distinguish between them through clinical examination alone, and there have been few published reports on this topic, especially from Asia.


Persistent homology of time-dependent functional networks constructed from coupled time series.

We use topological data analysis to study "functional networks" that we construct from time-series data from both experimental and synthetic sources. We use persistent homology with a weight rank clique filtration to gain insights into these functional networks, and we use persistence landscapes to interpret our results. Our first example uses time-series output from networks of coupled Kuramoto oscillators. Our second example consists of biological data in the form of functional magnetic resonance imaging ...

Arc - An endogenous neuronal retrovirus?

The neuronal gene Arc is essential for long-lasting information storage in the mammalian brain and has been implicated in various neurological disorders. However, little is known about Arc's evolutionary origins. Recent studies suggest that mammalian Arc originated from a vertebrate lineage of Ty3/gypsy retrotransposons, which are also ancestral to retroviruses. In particular, Arc contains homology to the Gag polyprotein that forms the viral capsid and is essential for viral infectivity. This surprising con...


Lifestyle predictors for non-participation and outcome in the second round of faecal immunochemical test in colorectal cancer screening.

To reduce colorectal cancer (CRC) mortality through population-based screening programmes using faecal tests, it is important that individuals continue to participate in the repeated rounds of screening. We aimed to identify lifestyle predictors for discontinuation of faecal immunochemical test (FIT) screening after the first round, as well as lifestyle predictors for colorectal neoplasia detected in the second-round FIT screening.

The contribution of homology arms to nuclease-assisted genome engineering.

Designer nucleases like CRISPR/Cas9 enable fluent site-directed damage or small mutations in many genomes. Strategies for their use to achieve more complex tasks like regional exchanges for gene humanization or the establishment of conditional alleles are still emerging. To optimize Cas9-assisted targeting, we measured the relationship between targeting frequency and homology length in targeting constructs using a hypoxanthine-guanine phosphoribosyl-transferase assay in mouse embryonic stem cells. Targeting...

Analysis of the influence of the transducer and its coupling layer on round window stimulation.

In this work, a finite element study is proposed to evaluate the effects of the transducer and its coupling layer on the performance of round window (RW) stimulation.

An analysis of equine round pen training videos posted online: Differences between amateur and professional trainers.

Natural Horsemanship is popular among many amateur and professional trainers and as such, has been the subject of recent scientific enquiry. One method commonly adopted by Natural Horsemanship (NH) trainers is that of round pen training (RPT). RPT sessions are usually split into a series of bouts; each including two phases: chasing/flight and chasing offset/flight offset. However, NH training styles are heterogeneous. This study investigated online videos of RPT to explore the characteristics of RPT session...

Outdoor Cultivation of Marine Diatoms for Year-Round Production of Biofuels.

Biofuel production using microalgae is believed to have the advantage of continuous year-round production over crop plants, which have strong seasonality. However, actual year-round production of microalgal lipids using outdoor mass cultivation has rarely been demonstrated. In our previous study, it was demonstrated that the oleaginous diatom, Fistulifera solaris, was culturable in outdoor bioreactors from spring to autumn, whereas biomass and lipid production in winter failed because F. solaris did not gro...

Clinical activity of eribulin in advanced desmoplastic small round-cell tumor.

Desmoplastic small round-cell tumor is a rare but highly aggressive tumor occurring mainly in adolescents and young adults. Prolonged progression-free survival has been documented in patients who have undergone aggressive multimodality therapy - that is, multiagent intensive chemotherapy, debulking surgery, and radiation therapy. Eribulin is a microtubule-dynamics inhibitor, and it has recently been shown to be active in liposarcomas. In preclinical models, eribulin activities have also been shown to occur ...

Pinniped Diphyly and Bat Triphyly: More Homology Errors Drive Conflicts in the Mammalian Tree.

Homology is perhaps the most central concept of phylogenetic biology. At difficult to resolve polytomies that are deep in the Tree of Life, a few homology errors in phylogenomic data can drive spurious phylogenetic results. Feijoo and Parada (2017) assembled three phylogenomic data sets for mammals and reported methodological discrepancies and unexpected results that contradict the monophyly of well-established clades in Pinnipedia and Yangochiroptera. Examination of Feijoo and Parada's (2017) data sets rev...

Portal vein branching order helps in the recognition of anomalous right-sided round ligament: common features and variations in portal vein anatomy.

This study aimed to evaluate the common features and variations of portal vein anatomy in right-sided round ligament (RSRL), which can help propose a method to detect and diagnose this anomaly.

Diagnostic Utility of Pax8, Pax2, and NGFR Immunohistochemical Expression in Pediatric Renal Tumors.

Pediatric renal tumors (PRT) with small round blue or spindle cell morphology can be diagnostically challenging and only a limited number of immunohistochemical markers have been documented to help in the diagnosis: paired box (Pax) 2 and nerve growth factor receptor (NGFR) positivity have been demonstrated in Wilms tumor (WT) and clear cell sarcoma of the kidney (CCSK), respectively. However, the immunohistochemical expression of these markers in other PRT remains unknown. This study investigated Pax8, Pax...

Role of Multislice CT Imaging in Predicting the Visibility of the Round Window in Pediatric Cochlear Implantation.

High-resolution computed tomography (HRCT) magnifies the role of preoperative imaging for detailed inner and middle ear anatomical information and enhances more efforts for better dependent correlation and measurements of round window (RW).

On the Mechanism of Homology Search by RecA Protein Filaments.

Genetic stability is a key factor in maintaining, survival, and reproduction of biological cells. It relies on many processes, but one of the most important is a homologous recombination, in which the repair of breaks in double-stranded DNA molecules is taking place with a help of several specific proteins. In bacteria, this task is accomplished by RecA proteins that are active as nucleoprotein filaments formed on single-stranded segments of DNA. A critical step in the homologous recombination is a search f...

ProtDec-LTR2.0: an improved method for protein remote homology detection by combining pseudo protein and supervised Learning to Rank.

As one of the most important tasks in protein sequence analysis, protein remote homology detection is critical for both basic research and practical applications. Here, we present an effective web server for protein remote homology detection called ProtDec-LTR2.0 by combining ProtDec-Learning to Rank (LTR) and pseudo protein representation. Experimental results showed that the detection performance is obviously improved. The web server provides a user-friendly interface to explore the sequence and structure...

Round and Oval Window Anatomic Variability: Its Implication for the Vibroplasty Technique.

Synthesis of a new series of aryl/heteroarylpiperazinyl derivatives of 8-acetyl-7-hydroxy-4-methylcoumarin with low nanomolar 5-HT1A affinities.

We synthesized a series of aryl/heteroarylpiperazinyl derivatives of 8-acetyl-7-hydroxy-4-methylcoumarin and evaluated their antidepressant-like activity. We used a fast, microwave-assisted synthesis protocol and (1)H, (13)C NMR and HRMS spectrometry to confirm the structure of all compounds. We also used radioligand binding assays to determine the affinities towards 5-HT1A and 5-HT2A receptors and performed molecular docking studies to rationalize obtained results. Among the evaluated compounds seven displ...

Sarcomas With CIC-rearrangements are a Distinct Pathologic Entity With Aggressive Outcome: A Clinicopathologic and Molecular Study of 115 Cases.

CIC-DUX4 gene fusion, resulting from either a t(4;19) or t(10;19) translocation, is the most common genetic abnormality detected in EWSR1-negative small blue round cell tumors. Following their discovery it was debated if these tumors should be classified as variants of Ewing sarcoma (ie, atypical Ewing sarcoma) or as a stand-alone pathologic entity. As such the WHO classification temporarily grouped the CIC-rearranged tumors under undifferentiated sarcomas with round cell phenotype, until further clinical e...

Guaiac-based faecal occult blood testing was used. All individuals invited to the three first consecutive screening rounds were included in the analysis. Results There were 346,...

Aberrant Expression of FLI-1 in Melanoma.

FLI-1 (Friend leukemia integration site 1) nuclear transcription factor has been proposed as a suitable tool in the differential diagnosis of small round cell sarcomas. It has also been described as nuclear marker of endothelial differentiation. Expression of FLI-1 has been demonstrated in Ewing's sarcoma/ primitive neuroectodermal tumor (ES/PNET) and vascular neoplasms. In the present study, we describe two cases of metastatic melanoma with small round blue cell morphology that showed strong nuclear expres...

Evolution of stinginess and generosity in finite populations.

In iterated continuous games, the cooperative investment in a given round is determined by the initial investment and the reciprocation rate, which describe the investment in the first round and the dependence of current investment on the partner's last move, respectively. These two traits usually intertwine during evolution. However, their coevolution is not fully explored. In this paper, we thereby study their coevolution in the iterated continuous public goods games. We find that the reciprocation rate p...

Electrospinning of gelatin with tunable fiber morphology from round to flat/ribbon.

The electrospinning of gelatin with tunable fiber morphology from round to flat/ribbon was shown, and the detailed studies were conducted to correlate the fiber morphology with electrospinning process parameters and gelatin concentration in electrospinning solution. Particularly, variations in the applied voltage and the concentration of gelatin led to the transition of fiber shape from round to flat/ribbon. The formation of flat-shaped fibers was attributed to rapid evaporation of the solvent (formic acid)...

The Combined Use of Proteomics and Transcriptomics Reveals a Complex Secondary Metabolite Network in Peperomia obtusifolia.

Peperomia obtusifolia, an ornamental plant from the Piperaceae family, accumulates a series of secondary metabolites with interesting biological properties. From a biosynthesis standpoint, this species produces several benzopyrans derived from orsellinic acid, which is a polyketide typically found in fungi. Additionally, the chiral benzopyrans were reported as racemic and/or as diastereomeric mixtures, which raises questions about the level of enzymatic control in the cyclization step for the formation of t...
