Obstructive Azoospermia in a Patient with VATER Association  [PDF]
Zhanyong Bing
Open Journal of Pathology (OJPathology) , 2012, DOI: 10.4236/ojpathology.2012.24030
Abstract: VATER association was first described in 1968 by Say and Gerald and is an association of congenital anomalies including V (vertebral defect), A (anal atresia), TE (tracheoesophegeal fistula), and R (radial dysplasia and renal defects). This report described a 26 year-old man with VATER association presented with infertility. Hormone tests including follicular stimulating hormone, luteinizing hormone and testosterone were normal. Semen analysis showed azoospermia. A testicular biopsy was performed and showed the presence of all of germinative components, germ cell sloughing, and mild hypospermatogenesis. The findings were compatible with obstructive azoospermia. No evidence of intratubular germ cell neoplasia unclassified was identified.
Multiple Circular Colouring as a Model for Scheduling  [PDF]
Bing Zhou
Open Journal of Discrete Mathematics (OJDM) , 2013, DOI: 10.4236/ojdm.2013.33029

In this article we propose a new model for scheduling periodic tasks. The model is based on a variation of the circular chromatic number, called the multiple circular colouring of the conflict graph. We show that for a large class of graphs, this new model will provide better solutions than the original circular chromatic number. At the same time, it allows us to avoid the difficulty of implementation when the fractional chromatic number is used.

Length of the Longest Path and Diameter in Orientations of Graphs  [PDF]
Bing Zhou
Open Journal of Discrete Mathematics (OJDM) , 2017, DOI: 10.4236/ojdm.2017.72007
Abstract: We say that a parameter p of directed graphs has the interval property if for every graph G?and orientations of G, p can take every value between its minimum and maximum values. Let λ be the length of the longest directed path. A question asked by C. Lin in [1] is equivalent to the question of whether λ has the interval property. In this note, we answer this question in the affirmative. We also show that the diameter of directed graphs does not have the interval property.
Measurement and Analysis of China’s Industrial Technical Efficiency  [PDF]
Bing Li
Journal of Financial Risk Management (JFRM) , 2018, DOI: 10.4236/jfrm.2018.71007
Abstract: This paper uses the stochastic frontier analysis to analyze the China’s technical efficiency on the basis of 280 cities from 1998 to 2015. The empirical results indicated that: the average technical efficiency of China’s industrial was increasing steadily in the past 18 years. The technical efficiency of east, middle and west regions are quite different: the east regions mean technical efficiency was higher than middle area about 27.3%, or higher than west area about 35.9%. In addition, the marketization process, R&D expenditure, education investment have a positive effect on the technical efficiency, but the FDI has a negative effect on eastern technical efficiency, which may due to the entry of FDI in eastern areas do not play a comparative advantage at the present stage.
Syntactic Ambiguity Resolution of Cantonese-English Bilinguals: Evidence from Prepositional Phrase and Adverb  [PDF]
Bing Bai
Open Journal of Modern Linguistics (OJML) , 2018, DOI: 10.4236/ojml.2018.83005
Abstract: Syntactic ambiguity resolution is influenced by multiple constraints. A sentence-picture matching task tested the attachment of prepositional phrase (PP) such as on the chair within an utterance like Mary ate the apple on the chair. PP attaching to NP2 (the apple) is called low attachment (LA), while PP attaching to V (ate) is called high attachment (HA). A comprehension task tested the attachment of adverb such as quickly within an utterance like the story Mary was reading quickly put her little sister into sleep. The checked adverbs attaching to the verb of the embedded clause (VEC) and to the verb of the main clause (VMC) were analyzed. Cantonese-English bilinguals were grouped according to their L2 proficiency. Results reflected that 1) both groups showed preference to HA for PP, 2) LP group showed preference to VMC for adverb attachment; 3) there is a large gap in LA between LP and HP, suggesting that syntactic ambiguity resolution involves interaction of all the information available. The relationship between language proficiency and parsing is not so definitely supported by the results.
Cross-species EST alignments reveal novel and conserved alternative splicing events in legumes
Bing-Bing Wang, Mike O'Toole, Volker Brendel, Nevin D Young
BMC Plant Biology , 2008, DOI: 10.1186/1471-2229-8-17
Abstract: Based on cognate EST alignments alone, the observed frequency of alternatively spliced genes is lower in Mt (~10%, 1,107 genes) and Lj (~3%, 92 genes) than in Arabidopsis and rice (both around 20%). However, AS frequencies are comparable in all four species if EST levels are normalized. Intron retention is the most common form of AS in all four plant species (~50%), with slightly lower frequency in legumes compared to Arabidopsis and rice. This differs notably from vertebrates, where exon skipping is most common. To uncover additional AS events, we aligned ESTs from other legume species against the Mt genome sequence. In this way, 248 additional Mt genes were predicted to be alternatively spliced. We also identified 22 AS events completely conserved in two or more plant species.This study extends the range of plant taxa shown to have high levels of AS, confirms the importance of intron retention in plants, and demonstrates the utility of using ESTs from related species in order to identify novel and conserved AS events. The results also indicate that the frequency of AS in plants is comparable to that observed in mammals. Finally, our results highlight the importance of normalizing EST levels when estimating the frequency of alternative splicing.Alternative splicing (AS) is an important cellular process that leads to multiple mRNA isoforms from a single pre-mRNA in eukaryotic organisms. Plant AS events used to be regarded as rare. However, a growing number of computational studies have now demonstrated that the frequency of alternatively spliced genes in plants is higher than previously estimated [1,2]. 20–30% of expressed genes are alternatively spliced in Arabidopsis thaliana (At) and rice (Oryza sativa, Os) as revealed by large scale EST-genome alignments [1,2]. A recent study using EST pairs gapped alignments (EST-EST) surveyed 11 plant species and suggested that overall AS frequencies vary greatly in different plant species, with some rates comparable to those

At present, the disease is incurable and the molecular pathophysiology of DD is unknown. Surgery remains the most commonly used treatment for DD, but this requires extensive postoperative therapy and is associated with high rates of recurrence. Over the past decades, more indepth exploration of the molecular basis of DD has raised the hopes of developing new treatment modalities. This paper reviews the clinical presentation and molecular pathophysiology of this disease, as well as current and emerging treatment. It also explores the implications of new findings in the laboratory for future treatment.

Abstract: ate on the management of Dupuytren’s contracture Review (4979) Total Article Views Authors: Linda Vi, David B O’Gorman, Bing Siang Gan Published Date August 2010 Volume 2010:2 Pages 35 - 43 DOI: http://dx.doi.org/10.2147/ORR.S8592 Linda Vi1, David B O’Gorman2, Bing Siang Gan3 1Department of Physiology and Pharmacology, 2Hand and Upper Limb Centre, Lawson Health Research Institute, Departments of Surgery and Biochemistry, 3Hand and Upper Limb Centre, Lawson Health Research Institute, Departments of Surgery and Medical Biophysics, University of Western Ontario, London, Ontario, Canada Abstract: Dupuytren’s disease (DD) is a pathological condition of the palmar fascia that is characterized by the formation of tight collagenous disease cords leading to permanent finger contractures. The disease is most prevalent in Caucasian men, and its incidence increases with age advancement. The most common complaint from patients having DD is the impairment of normal hand function. At present, the disease is incurable and the pathophysiology of DD is unknown. The most common treatment for DD is surgery; however, this treatment is associated with a high rate of recurrence. More recently, researchers have begun to explore the molecular basis of DD in the hopes of developing new, more effective treatment for DD. This review will summarize the history and clinical presentation of the disease, highlight current and emerging molecular treatments, and explore the implications of these advancements for future work.
