Homology of pendrin, sodium-iodide symporter and apical iodide transporter.

We observed local homology between human pendrin and sodium/iodide symporter (NIS), that was absent in the NIS-homologous sodium/monocarboxylate transporter or apical iodide transporter (AIT) which, however, does not transport iodide. Thus, we analyzed the full proteins. They shared 63 identical and 66 similar residues (overall homology 14.4%, but 21% when omitting intervening sequences of 15 or more residues). Pendrin was more homologous to NIS (25%) than AIT (20%), particularly in the STAS domain (sulfate...

Surgical Anatomy of the Round Window - Implications for Cochlear Implantation.

The round window is an important portal for the application of active hearing aids and cochlear implants. The anatomical and topographical knowledge about the round window region is a prerequisite for successful insertion for a cochlear implant electrode.

Rhabdomyosarcoma, Ewing Sarcoma, and Other Round Cell Sarcomas.

Several recent advances have been made in the diagnosis and therapy of malignant small round cell tumors that affect children, particularly in rhabdomyosarcoma, Ewing sarcoma, and other round cell sarcomas. These advances have provided new insights into the pathologic, histologic, and genomic characterization of specific tumor subtypes, which has led to the identification of novel therapeutic targets and improved stratification of risk. This has, in turn, led to improved efficacy in clinical trials of new d...

PAX7 Immunohistochemical Evaluation of Ewing Sarcoma and Other Small Round Cell Tumors.

Ewing sarcoma is a small round cell tumor that affects bone and soft tissues. Although the detection of the specific fusion gene is a robust method of its diagnosis, immunohistochemistry may serve as a practical surrogate. Recent tissue microarray studies suggested that PAX7 is a novel marker, because it was consistently expressed in Ewing sarcoma, in addition to rhabdomyosarcoma and synovial sarcoma. Here, we evaluated the utility of PAX7 immunohistochemistry in whole-tissue sections of an expanded array o...

Assessing GPCR homology models constructed from templates of various transmembrane sequence identities: Binding mode prediction and docking enrichment.

GPCR crystal structures have become more readily accessible in recent years. However, homology models of GPCRs continue to play an important role as many GPCR structures remain unsolved. The new crystal structures now available provide not only additional templates for homology modelling but also the opportunity to assess the performance of homology models against their respective crystal structures and gain insight into the performance of such models. In this study we have constructed homology models from ...

Double cross finger flaps from the middle to the index or ring finger: A case series of 4 patients with an emphasis on donor finger morbidity.

The use of two cross finger flaps from one digit has not been previously reported and the technique raises concerns regarding donor finger morbidity. In this paper, the authors report on a case series of double cross fingers flaps harvested from the middle finger to reconstruct large defects in the adjacent index or ring finger; with an emphasis on documenting morbidity in the donor middle finger.

Locking Plate Fixation in a Series of Bicondylar Tibial Plateau Fractures Raises Treatment Costs Without Clinical Benefit.

To compare outcomes and costs between locking and nonlocking constructs in the treatment of bicondylar tibial plateau (BTP) fractures.

Environmental DNA (eDNA): A tool for quantifying the abundant but elusive round goby (Neogobius melanostomus).

Environmental DNA (eDNA) is revolutionizing biodiversity monitoring, occupancy estimates, and real-time detections of invasive species. In the Great Lakes, the round goby (Neogobius melanostomus), an invasive benthic fish from the Black Sea, has spread to encompass all five lakes and many tributaries, outcompeting or consuming native species; however, estimates of round goby abundance are confounded by behavior and habitat preference, which impact reliable methods for estimating their population. By integra...

In vitro screening, homology modeling and molecular docking studies of some pyrazole and imidazole derivatives.

A series of synthesized compounds based on pyrazole and imidazole skeletons prepared by palladium catalysts via a one-pot reaction was screened to determine their inhibitory potency against the pathogen fungus Fusarium oxysporum f.sp. albedinis (F.o.a) and four bacteria strains namely Micrococcus luteus, Bacillus subtilis, Staphylococcus aureus and Escherichia coli. The obtained result showed that these compounds exhibit an efficiency antifungal action. Whereas, they showed a very weak antibacterial activit...

SWISS-MODEL: homology modelling of protein structures and complexes.

Homology modelling has matured into an important technique in structural biology, significantly contributing to narrowing the gap between known protein sequences and experimentally determined structures. Fully automated workflows and servers simplify and streamline the homology modelling process, also allowing users without a specific computational expertise to generate reliable protein models and have easy access to modelling results, their visualization and interpretation. Here, we present an update to th...

An unusual case of lung abscess secondary to round pneumonia caused by recurrent strain and the role of occult metastases tumor.

Round pneumonia is an uncommon form of community-acquired pneumonia usually found in children. To this date, there has been no report on local pulmonary complications in this entity in adult patients. The present study reports a case of a 77-year-old male with lung abscess secondary to round pneumonia caused by recurrent infection accompanied by occult metastases tumor. Occult metastases may have played an important role in leading to cavity as in this present case. Further investigation regarding the rela...

Aptamers as biomarkers for neurological disorders. Proof of concept in transgenic mice.

The act of selecting aptamers against blood serum leads to deep libraries of oligonucleotide sequences that bind to a range of epitopes in blood. In this study we developed an enriched aptamer library by performing positive selection against a pool of blood serum samples from transgenic mice (P301S) carrying the human tau gene and counter selecting against pooled blood serum from negative segregant (wild type) mice. We demonstrated that a large proportion of the aptamer sequences observed with next generati...

Oocyte-Activating Capacity of Fresh and Frozen-Thawed Spermatids in the Common Marmoset (Callithrix jacchus).

The common marmoset (Callithrix jacchus) represents a promising nonhuman primate model for the study of human diseases because of its small size, ease of handling, and availability of gene-modified animals. Here, we aimed to devise reproductive technology for marmoset spermatid injection using immature males for a possible rapid generational turnover. Spermatids at each step could be identified easily by their morphology under differential interference microscopy: thus, early round spermatids had a round nu...

Application value of frozen-thawed mouse round spermatids in in vitro fertilization.

To investigate the application value of the frozen-thawed round spermatids of the mouse in in vitro fertilization (IVF).

Homology threading to generate RNA polymerase structures.

Homology threading is a powerful technology for generating structural models based on homologous structures. Here we use threading to generate four complex RNA polymerase models. The models appear to be as useful as x-ray crystal structures or cryo-electron microscopy structures to support research projects.

Neural Basis for Producing Temporal Order.

It has been proposed that a position in time can be discriminated in two ways. First, each position is either past, present, or future (A series). Second, each position is either before or after another (B series). In this review, we aim to infer how the two series are represented in the brain on the basis of findings from clinical, neurophysiological, and neuroimaging studies. We suggest that the precuneus and posterior cingulate cortex are critically involved in the A series. In the B series, we suggest t...

Invasion strategies in round goby (Neogobius melanostomus): Is bigger really better?

Few studies have systematically investigated mid- or long-term temporal changes of biological characteristics in invasive alien species considering the different phases of an invasion. We studied the invasion performance of one of the most invasive species worldwide, the round goby Neogobius melanostomus, from total absence over first occurrence until establishment from 2010 to 2015 in the upper Danube River. After an upstream movement of the invasion front of about 30 river km within four years, the patter...

Tracheal acid or surfactant instillation raises alveolar surface tension.

Whether alveolar liquid surface tension, T, is elevated in the acute respiratory distress syndrome (ARDS) has not been demonstrated in situ in the lungs. Neither is it known how exogenous surfactant, which has failed to treat ARDS, affects in situ T. We aim to determine T in an acid-aspiration ARDS model before and after exogenous surfactant administration. In isolated rat lungs, we combine servo-nulling pressure measurement and confocal microscopy to determine alveolar liquid T according to the Laplace rel...

A novel image-based system for risk stratification in patients with desmoplastic small round cell tumor.

Desmoplastic small round cell tumor (DSRCT) is an aggressive soft tissue sarcoma affecting children and young adults with 5-year overall survival (OS) of approximately 20%. Despite generally poor prognosis, long-term survival does occur. However, no evidence-based system exists to risk-stratify patients at diagnosis.

A low-complexity add-on score for protein remote homology search with COMER.

Protein sequence alignment forms the basis for comparative modeling, the most reliable approach to protein structure prediction, among many other applications. Alignment between sequence families, or profile-profile alignment, represents one of the most, if not the most, sensitive means for homology detection but still necessitates improvement. We aim at improving the quality of profile-profile alignments and the sensitivity induced by them by refining profile-profile substitution scores.

Causative factors, imaging findings, and CT course of round atelectasis.

To assess causative factors, associated imaging findings, and CT course of round atelectasis (RA).

Ultra-fast global homology detection with Discrete Cosine Transform and Dynamic Time Warping.

Evolutionary information is crucial for the annotation of proteins in bioinformatics. The amount of retrieved homologs often correlates with the quality of predicted protein annotations related to structure or function. With a growing amount of sequences available, fast and reliable methods for homology detection are essential, as they have a direct impact on predicted protein annotations.
