Malongitubus: a possible pterobranch hemichordate from the early Cambrian of South China

Abstract. Malongitubus kuangshanensis Hu, 2005 from the early Cambrian Chengjiang Lagerstätte of China is redescribed as a pterobranch and provides the best evidence to demonstrate that hemichordates were present as early as Cambrian Stage 3. Interpretation of this taxon as a hemichordate is based on the morphology of the branched colony and the presence of resistant inner threads consistent with the remains of an internal stolon system. The presence of fusellar rings in the colonial tubes cannot be unambiguously proven for Malongitubus, probably due to early decay and later diagenetic replacement of the thin organic material of the tubarium, although weak annulations are still discernible in parts of the tubes. The description of M. kuangshanensis is revised according to new observations of previously reported specimens and recently collected additional new material. Malongitubus appears similar in most features to Dalyia racemata Walcott, 1919 from the Cambrian Stage 5 Burgess Shale, but can be distinguished by the existence of disc-like thickenings at the bases of tubarium branching points in the latter species. Both species occur in rare mass-occurrence layers with preserved fragmentary individuals of different decay stages, with stolon remains preserved as the most durable structures. Benthic pterobranchs may have occurred in some early Cambrian shallow marine communities in dense accumulations and provided firm substrates and shelter for other benthic metazoans as secondary tierers.
Aggressive Driving in Young Motorists

Road rage is an increasingly prevalent expression of aggression in our society. Its dangers are apparent and understanding its causes may shed light on preventative measures. This study involved a fifteen-minute survey administered to 147 undergraduate students at a North Eastern suburban university. The survey consisted of a demographics section, questions regarding financial investment in respondents’ vehicles, experience driving, habits of driving, experiences witnessing role models driving, and an evaluation of road rage behavior using the Driving Vengeance Questionnaire. The study found no significant differences in driving aggression between respondents who were financially invested in their vehicle compared to those who were not, or between respondents who drove in heavy traffic hours compared to those who did not, suggesting internal factors correlate with aggressive driving habits. The study also found significant differences in driving aggression between males versus females, those with more points on their license versus fewer points, and those who witnessed parents driving aggressively very often versus rarely or never. Additional studies can investigate how witnessing parents driving aggressively is related to future driving behaviors. Keywords—Aggression, college, driving, road rage.
A Study on the Strategy of Chinese-English Consecutive Interpreting of Beijing Historical and Cultural Speeches

Historical and cultural speeches are considered a challenge in Chinese to English interpretation, as each language describes the world in a different way. Therefore, Beijing historical and cultural speeches are believed to have high level of difficulty in terms of interpretation. This study was aimed at investigating the strategies used in interpreting Beijing historical and cultural speeches. Based on the literature review, two models of interpretation are established, and three cases of interpreting strategy of Beijing historical and cultural speeches based on the models are analyzed.
Incident Angle of Saltating Particles in Wind-Blown Sand

Incident angle of saltating particles plays a very important role in aeolian events. In this paper, the incident angles of sand particles near the sand bed were measured in wind tunnel. It reveals that the incident angles range widely from 0° to 180° and thereby the means of angles are larger than published data. Surprisingly, it is found the proportion that angles of 5°–15° occupy is far below previous reports. The measuring height is probably the most important reason for the measurement differences between this study and previous investigations.
Collaborative Data Analytics with DataHub

While there have been many solutions proposed for storing and analyzing large volumes of data, all of these solutions have limited support for collaborative data analytics, especially given the many individuals and teams are simultaneously analyzing, modifying and exchanging datasets, employing a number of heterogeneous tools or languages for data analysis, and writing scripts to clean, preprocess, or query data. We demonstrate DataHub, a unified platform with the ability to load, store, query, collaboratively analyze, interactively visualize, interface with external applications, and share datasets. We will demonstrate the following aspects of the DataHub platform: (a) flexible data storage, sharing, and native versioning capabilities: multiple conference attendees can concurrently update the database and browse the different versions and inspect conflicts; (b) an app ecosystem that hosts apps for various data-processing activities: conference attendees will be able to effortlessly ingest, query, and visualize data using our existing apps; (c) thrift-based data serialization permits data analysis in any combination of 20+ languages, with DataHub as the common data store: conference attendees will be able to analyze datasets in R, Python, and Matlab, while the inputs and the results are still stored in DataHub. In particular, conference attendees will be able to use the DataHub notebook - an IPython-based notebook for analyzing data and storing the results of data analysis.
In vitro and in vivo quality of leukoreduced apheresis platelets stored in a new platelet additive solution

BACKGROUND: Platelets (PLTs) stored in additive solutions (PASs) may reduce the risk of several plasma‐associated adverse transfusion reactions such as allergic reactions and potentially transfusion‐associated lung injury. The objective of this study was to determine the in vitro characteristics and the in vivo radiolabeled recovery and survival of apheresis PLTs (APs) stored in a new PAS and compare the latter to Food and Drug Administration (FDA) criteria.
High plasma C‐reactive protein (CRP) is related to low paraoxonase‐I (PON‐I) activity independently of high leptin and low adiponectin in type 2 diabetes mellitus

Objectives In type 2 diabetes mellitus, circulating C‐reactive protein (CRP) is increased, whereas the high density lipoprotein (HDL)‐associated, anti‐oxidative and anti‐inflammatory enzyme, paraoxonase‐I, is decreased. Both high CRP and low paraoxonase‐I activity may predict cardiovascular disease. It is unknown whether lower paraoxonase‐I activity contributes to higher CRP levels in diabetes. In type 2 diabetic and control subjects, we determined the relationship of CRP with paraoxonase‐I when taking account of plasma levels of pro‐ and anti‐inflammatory adipokines.
Variables with a negative impact on the quality of life of gays and lesbians in Spain: evaluation of homophobic and lesbophobic indicators to guide youth education

Background Despite the evidence about the negative impact of homophobic and lesbophobic attitudes on the quality of life of these individuals, the World Health Organisation (WHO) continues to report a lack of research and understanding regarding the health of gays and lesbians and LGTB people in general. There is a growing commitment in public health to understand and improve the health and well-being of LGTB people, and it is very important that professionals in social, educational and health care settings are adequately trained and informed to solve the problems that persist in this population. The aim of this study was to identify homophobic and lesbophobic attitudes in a Spanish youth population, analyzing the relationship of these attitudes with sociodemographic, cultural, political and personal variables. Methods A descriptive, cross-sectional study was carried out with 325 young people aged 18–30 years. The information was collected through the Modern Homophobia Scale of Raja & Stokes, in which sociodemographic and sociocultural variables were also gathered. The data were analyzed and correlations were estimated. Results The males showed a more negative attitude toward homosexual people compared to the females. The participants with a higher education level presented more positive attitudes toward homosexual people. Younger people with a heterosexual orientation had more negative attitudes toward homosexual people compared to those with a homosexual orientation. The participants with a stronger right-wing political tendency presented a greater percentage of negative attitudes toward LGTB people. Conclusion Variables such as education level, sexual orientation and political ideology may have a significant influence on the attitudes toward homosexual men and/or lesbian women. Different results were obtained as a function of sex, thus it is important to consider the gender perspective in future studies that tackle this topic.
Enabling large-scale wireless broadband

The vision is tantalizing: a high-performance, scalable, and widely deployed wireless Internet that facilitates services ranging from radically new and unforeseen applications to true wireless "broadband" to residences and public spaces at rates of 10s of Mb/sec. However, while high-speed wireless access is easy to achieve in an enterprise network via low-cost IEEE 802.11 (WiFi) access points, wireless technology in public spaces is in its infancy. "Hot spots" provide high-speed wireless access, but do so in very few isolated "islands" at immense costs. Likewise, while fixed wireless (e.g. LMDS) and 3G can provide ubiquitous coverage and 3G can support mobility, throughputs can often be two orders of magnitude slower than WiFi.In this paper, we formulate the challenges of building a high-performance, scalable and widely deployed wireless Internet along 10 premises. We make the case for the requirement of a fundamental new architecture based on beamforming antennas deployed on fixed, wire-powered Transit Access Points (TAPs) that form a multi-hopping wireless backbone with a limited number of wired ingress/egress points. To address scalability, deployability, and performance challenges we present distributed, opportunistic and coordinated resource management problems and a novel "network is the channel" framework that searches for fundamental information-theoretic tradeoffs between protocol overhead and capacity.
Coats' disease in Tanzania: first case report and literature review.

BACKGROUND Coats' disease is an exudative retinal detachment with vascular telangiectasis occurring mostly in male children, the age group most affected by retinoblastoma. OBJECTIVES Compare the differential diagnoses of Coats' disease Establish recommendation to early disease detection. MATERIALS AND METHODS A 3-year-old female child was referred to Muhimbili National Hospital (MNH), Tanzania, in September 2011. She had presented at the peripheral hospital with gradual onset of left eye leukocoria for 1 year and pain for 2 months. B-scan showed a mass in the left eye. A clinical diagnosis of retinoblastoma was made. Left eye enucleation was performed; the patient was referred to MNH, with the enucleated specimen. RESULTS Brain and orbits scan revealed no residual tumour. The globe measured 2 x 1.8 cm, the optic nerve stump measured 3 mm. A whitish mass filled the vitreous, with complete retinal detachment. Microscopy showed retinal gliosis, detachment with sub retinal PAS positive exudates, vacuolation and cholesterol clefts. Foreign body giant cells were present; telangiectatic thin-walled blood vessels were identified. Clinico-pathological findings were of stage 4 Coats' disease. CONCLUSION Coats' disease is an important differential diagnosis of retinoblastoma. Delay to detect Coats' disease leads to vision loss which necessitates eye enucleation as was in this child.
Response of Transplanted Aman Rice Varieties to Herbicides in Strip-Tilled Non-Puddled Soil

Academic Editor: Md. Shafiqul Islam Sensitivity of crop cultivars may vary to commonly used herbicides resulting in potential yield loss and reduce farm profit. Transplanting of rice seedlings in striptilled non-puddled field is a new practice for which herbicide tolerant varieties need to select. Therefore, a study was executed at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during 2013 to evaluate the response of some popular transplanted aman rice varieties to different herbicides at their recommended rate and to select most tolerant aman rice variety or varieties for strip-tilled non-puddled transplanting. Twelve aman rice varieties (BR11, BRRI dhan33, BRRI dhan39, BRRI dhan44, BRRI dhan46, BRRI dhan49, BRRI dhan51, BRRI dhan52, BRRI dhan56, BRRI dhan57, BRRI hybrid dhan-4 and BINA dhan7) were examined in the study against six herbicides (2 pre-emergence: pyrazosulfuron-ethyl and butachlor; 1 early post-emergence: orthosulfamuron and 3 late post-emergence: acetochlor + bensulfuron methyl, butachlor + propanil and 2,4-D amine) along with one untreated manually weed-free control. The study revealed that aman rice varieties responded differentially to different herbicides. All rice varieties performed better in pyrazosulfuron-ethyl treated plots relative to the other herbicide treated plots and even than the control plots. Pyrazosulfuronethyl increased grain yield of all aman rice varieties by 0.6-32.6% over control and butachlor + propanil provided increased grain yield in all rice varieties by 2.025. 5% except BRRI hybrid dhan-4. The study also disclosed that BRRI dhan57 and BRRI hybrid dhan-4 gone through the yield loss by application of 2,4-D amine and BRRI dhan56 by application of butachlor and orthosulfamuron. Moreover, acetochlor + bensulfuron methyl made plants shorter and caused yield loss by 7.827. 1% in all aman rice varieties and BRRI dhan39 was the most susceptible variety to this herbicide. Therefore, the study concluded that all transplanted aman rice varieties were tolerant to the recommended rate of pyrazosulfuron-ethyl. BRRI dhan33, BRRI dhan46, BRRI dhan51 and Binadhan-7 were the tolerant aman rice varieties for strip-tilled non-puddled transplanting. All over, this study demands that breeder should undergo the herbicide sensitivity test before release of rice varieties.
Insulin receptor isoform switching in intestinal stem cells, progenitors, differentiated lineages and tumors: evidence that IR-B limits proliferation

Summary Despite evidence for the impact of insulin on intestinal epithelial physiology and pathophysiology, the expression patterns, roles, and regulation of insulin receptor (IR) and IR isoforms in the intestinal epithelium are not well characterized. IR-A is thought to mediate the proliferative effects of insulin or insulin growth factors (IGFs) in fetal or cancer cells. IR-B is considered to be the metabolic receptor for insulin in specialized tissues. This study used a novel Sox9-EGFP reporter mouse that permits isolation of intestinal epithelial stem cells (IESCs), progenitors, enteroendocrine cells and differentiated lineages, the ApcMin/+ mouse model of precancerous adenoma and normal human intestinal and colorectal cancer (CRC) cell lines. We tested the hypothesis that there is differential expression of IR-A or IR-B in stem and tumor cells versus differentiated intestinal epithelial cells (IECs) and that IR-B impacts cell proliferation. Our findings provide evidence that IR-B expression is significantly lower in highly proliferative IESCs and progenitor cells versus post-mitotic, differentiated IECs and in subconfluent and undifferentiated versus differentiated Caco-2 cells. IR-B is also reduced in ApcMin/+ tumors and highly tumorigenic CRC cells. These differences in IR-B were accompanied by altered levels of mRNAs encoding muscleblind-like 2 (MBNL2), a known regulator of IR alternative splicing. Forced IR-B expression in subconfluent and undifferentiated Caco-2 cells reduced proliferation and increased biomarkers of differentiation. Our findings indicate that the impact of insulin on different cell types in the intestinal epithelium might differ depending on relative IR-B∶ IR-A expression levels and provide new evidence for the roles of IR-B to limit proliferation of CRC cells.
Preoperative Values of Molecular Coagulation Markers Identify Patients at Low Risk for Intraoperative Haemostatic Disorders and Excessive Blood Loss

Abstract Conventional laboratory investigations of haemostasis like prothrombin time and activated partial thromboplastin time are not useful in predicting and managing intra-operative bleeding complications. In order to establish a possible “perioperative reference range” for thrombin generation prothrombin fragment F1+2 (F1+2) and fibrin degradation (D-dimer) markers, we measured F1+2 and D-dimer concentrations before surgery (but after induction of anaesthesia), 30 minutes into surgery, 10 minutes after the event expected to induce the maximal activation of the haemostatic systems, 90 minutes after surgery and on postoperative days 1 and 2 in 226 consecutive patients. Samples were collected from arterial lines. Twenty patients developed a clinically defined, intraoperative disorder of haemostasis, 206 did not. Patients with an intraoperative disorder of haemostasis had significantly higher preoperative F1+2 and D-dimer concentrations. Preoperative values for F1+2 and D-dimer concentrations above the 75th percentile of patients without an intraoperative disorder of haemostasis indicated a 2.70 to 2.88 fold risk of developing an intraoperative disorder of haemostasis (odds ratios were 3.04, 3.12 and 3.29 for D-dimer, ELISA, F1+2, and D-dimer latex tests, respectively with 95% confidence intervals from 1.20 to 8.46) with negative predictive values of 94%, but positive predictive values of only 16% to 26%. These data suggest that preoperative determination of molecular markers might be helpful in identifying a group of patients at high risk for intraoperative disorder of haemostasis by exclusion of low risk patients. Validation of such an approach requires a prospective trial.
Proteomic analysis of aqueous humour from patients with acute corneal rejection.

PURPOSE To compare the basic proteomic composition of aqueous humour (AH) from patients with corneal rejection (patients) with AH from patients with cataract (controls). METHODS Aqueous humour was analysed for total protein concentration using Bradford's method and for protein composition using two-dimensional (2D) gel electrophoresis. Image analysis was used to detect protein spots in 2D gels that were increased by more than factor 2 in patients as compared with controls. Increased spots were identified by immunoblotting and mass spectrometry. RESULTS Aqueous humour from patients contained significantly higher total protein concentration than did AH from controls. A total of 31 spots were significantly increased in 2D gels from patients. The spots were derived from albumin, alpha1-antitrypsin, apolipoprotein J, cytokeratin type II, serin proteinase inhibitor and transthyretin. After correction of spot volumes by total protein concentrations, 10 spots derived from albumin, cytokeratin type II and alpha1-antitrypsin remained significantly increased. CONCLUSION The proteomic composition of AH differed significantly between patients and controls. The identified proteins suggest that the changes in AH are due to at least three different mechanisms: breakdown of the aqueous-blood barrier, enzymatic degradation, and liberation of locally synthesized proteins.
Antireflux Endoluminal Therapies: Past and Present

The basic principle of antireflux procedures employing endoscopic intervention aims to create a mechanical barrier to prevent primary pathophysiology in gastroesophageal reflux disease (GERD). We review, highlight, and discuss the past and present status of endoluminal therapy. Currently, there are 3 commonly employed anti-reflux endoluminal procedures: fundoplication or suturing techniques (EndoCinch, NDO, and EsophyX), intramural injection or implant techniques (enhancing lower esophageal sphincter (LES) volume and/or strengthening compliance of the LES-Enteryx and Gatekeeper), and radiofrequency ablation of LES and cardia. EndoCinch plication requires further study and modification of technique before it can be recommended because of durability issues. Esophynx, the transoral incisionless fundoplication, may reduce hiatal hernias and increase LES length. Preliminary studies have shown promising reduction in symptoms and medication use but evidence concerning safety and long-term durability is still pending. The safety issue with injection technique is the main concern as evident from the incidences of implant withdrawals after reported major adverse events. Future research with cautious monitoring is required before any new implant material can be recommended for commercial application. Radiofrequency ablation therapy is regaining popularity in treating refractory symptoms despite PPI use due to improved efficacy, durability, and safety after years of refinement of protocol.
Random Sampling for Continuous Streams with Arbitrary Updates

The existing random sampling methods have at least one of the following disadvantages: they 1) are applicable only to certain update patterns, 2) entail large space overhead, or 3) incur prohibitive maintenance cost. These drawbacks prevent their effective application in stream environments (where a relation is updated by a large volume of insertions and deletions that may arrive in any order), despite the considerable success of random sampling in conventional databases. Motivated by this, we develop several fully dynamic algorithms for obtaining random samples from individual relations, and from the join result of two tables. Our solutions can handle any update pattern with small space and computational overhead. We also present an in-depth analysis that provides valuable insight into the characteristics of alternative sampling strategies and leads to precision guarantees. Extensive experiments validate our theoretical findings and demonstrate the efficiency of our techniques in practice
