Intraaortic Balloon Counterpulsation: A Review

The intraaortic balloon counterpulsation pump (IABP) was successfully placed in 54 patients from 1972 to January 1978. Total overall survival was 46% (25/54). In the past 3 years survival was doubled (54% — 21/39) compared to the initial experience from 1972 through 1975 (27% — 4/15). Eleven percent (6/54) of the patients died after the IABP was removed, 19% (10/54) became balloon-dependent, and 24% (13/54) had either a poor response or no re sponse to IABP. Indications for IABP were cardiogenic shock secondary to myocardial infarction (CS-MI), preinfarction angina, postoperative cardiopulmonary bypass dependency (CPBD), the most common indication, or post cardi otomy cardiogenic shock. Preoperative prophylactic placement of the balloon was used in 7 patients with a 57% (4/7) survival. None of the 10 patients treated for CS-MI survived to discharge. Fifty-one percent (18/35) of CPBD patients were long-term survivors. Complications including difficulty passing the device (15/54), thrombosis (6/54), minor dissection (3/54), or combinations of these problems occurred in 41% (22/54) of the patients. Hemodynamic and metabolic parameters were also reviewed. Early recognition of cardiogenic shock and prompt placement of the IABP are essential to insure decreased morbidity and increased survival in these critically ill patients.
A novel training sequence applied to DCS-based channel estimation

Studies have indicated that the distributed compressed sensing based (DCS-based) channel estimation can decrease the length of the reference signals effectively. In block transmission, a unique word (UW) can be used as a cyclic prefix and reference signal. However, the DCS-based channel estimation requires diversity sequences instead of UW. In this paper, we proposed a novel method that employs a training sequence (TS) whose duration time is slightly longer than the maximum delay spread time. Based on proposed TS, the DCS approach perform perfectly in multipath channel estimation. Meanwhile, a cyclic prefix construct could be formed, which reduces the complexity of the frequency domain equalization (FDE) directly. Simulation results demonstrate that, by using the method of simultaneous orthogonal matching pursuit (SOMP), the required channel overhead has been reduced thanks to the proposed TS.
The Influence of Body Mass Index on Functional Outcomes, Satisfaction, and Return to Work After Single-level Minimally-invasive Transforaminal Lumbar Interbody Fusion: A Five-year Follow-up Study

Study Design. Retrospective study using prospectively collected registry data. Objectives. To evaluate the effect of obesity on patient-reported outcome measures of pain, disability, quality of life, satisfaction, and return to work after single-level minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF). Summary of Background Data. MIS-TLIF is an appealing alternative for obese patients with potentially lower complication risk. However, there is limited data investigating the influence of obesity on outcomes 5 years after MIS-TLIF. Methods. Prospectively collected registry data of 296 patients who underwent single-level MIS-TLIF at a single institution were reviewed. Patients had complete 2- and 5-year follow-up data. Patients were stratified into control (<25.0 kg/m2), overweight (25.0–29.9 kg/m2), and obese (≥30.0 kg/m2) groups. Outcomes assessed were visual analogue scale for back pain, leg pain, Oswestry Disability Index, Short-form 36, North American Spine Society score for neurogenic symptoms, return to work (RTW), return to function (RTF), satisfaction, and expectation fulfilment. Length of operation, length of stay, and comorbidities were recorded. Results. Among the patients, 156 (52.7%) had normal weight, 108 (36.5%) were overweight, and 32 (10.8%) were obese. There was no difference in length of operation or hospitalization (P > 0.05). All three groups had comparable preoperative scores at baseline (P > 0.05). At 5 years, the control group had significantly higher PCS compared with the overweight (P = 0.043) and obese groups (P = 0.007), although the change in scores was similar (P > 0.05). The rate of MCID attainment, RTW, RTF, expectation fulfilment, and satisfaction was comparable. Conclusion. Nonobese patients had better physical well-being in the mid-term, although obese patients experienced a comparable improvement in clinical scores. Obesity had no impact on patients’ ability to RTW or RTF. Equivalent proportions of patients were satisfied and had their expectations fulfilled up to 5 years after MIS-TLIF. Level of Evidence: 3

Characterization of the Multi-Drug Resistance Gene cfr in Methicillin-Resistant Staphylococcus aureus (MRSA) Strains Isolated From Animals and Humans in China

We investigated cfr-positive and -negative MRSA strains isolated from animals and humans in different geographical areas of China, from 2011 to 2016. Twenty cfr-positive strains (15.6%) were identified from 128 MRSA strains including 17 from food animals and three from humans. The resistance rates and prevalence of the tested antibiotic resistance genes (ARGs) in the cfr-positive MRSA isolates were higher than that in the cfr-negative MRSA isolates. All cfr-positive MRSA isolates were co-carrying fexA and ermC, and had significantly higher optrA incidence rate vs. the cfr-negative isolates (P < 0.05). In addition, multilocus sequence typing (MLST) assays showed that ST9 and spa-type t899 were the most prevalent ST and spa types in the study strains. However, all of the 20 cfr-positive and 10 randomly selected cfr-negative MRSA isolates were clonally unrelated as determined by pulsed-field gel electrophoresis (PFGE) analyses. Importantly, the cfr gene was successfully transferred to a recipient Staphylococcus aureus strain RN4220 from 13 of the 20 cfr-positive MRSA isolates by electroporation. Among these 13 cfr-positive MRSA isolates, two different genetic contexts surrounding cfr were determined and each was associated with one type of cfr-carrying plasmids. Of note, the predominant genetic context of cfr was found to be a Tn558 variant and locate on large plasmids (∼50 kb) co-harboring fexA in 11 of the 13 MRSA isolates. Furthermore, the cfr gene was also identified on small plasmids (∼ 7.1 kb) that co-carried ermC in two of the 13 MRSA isolates. Our results demonstrated a high occurrence of multi-drug resistance in cfr-positive MRSA isolates, and the spread of cfr might be attributed to horizontal dissemination of similar cfr-carrying transposons and plasmids.
RT States: systematic annotation of the human genome using cell type-specific replication timing programs

The replication timing (RT) program has been linked to many key biological processes including cell fate commitment, 3D chromatin organization and transcription regulation. Significant technology progress now allows to characterize the RT program in the entire human genome in a high-throughput and high-resolution fashion. These experiments suggest that RT changes dynamically during development in coordination with gene activity. Since RT is such a fundamental biological process, we believe that an effective quantitative profile of the local RT program from a diverse set of cell types in various developmental stages and lineages can provide crucial biological insights for a genomic locus. In the present study, we explored recurrent and spatially coherent combinatorial profiles from 42 RT programs collected from multiple lineages at diverse differentiation states. We found that a Hidden Markov Model with 15 hidden states provide a good model to describe these genome-wide RT profiling data. Each of the hidden state represents a unique combination of RT profiles across different cell types which we refer to as “RT states”. To understand the biological properties of these RT states, we inspected their relationship with chromatin states, gene expression, functional annotation and 3D chromosomal organization. We found that the newly defined RT states possess interesting genome-wide functional properties that add complementary information to the existing annotation of the human genome.

Diverse, Novel Mycoviruses From the Virome of a Hypovirulent Sclerotium rolfsii Strain

Sclerotium rolfsii, which causes southern blight in a wide variety of crops, is a devastating plant pathogen worldwide. Mycoviruses that induce hypovirulence in phytopathogenic fungi are potential biological control resources against fungal plant diseases. However, in S. rolfsii, mycoviruses are rarely reported. In a previous study, we found a hypovirulent strain carrying a diverse pattern of dsRNAs. Here, we utilized the RNA_Seq technique to detect viral sequences. Deep sequencing, RT-PCR and Sanger sequencing validation analyses revealed that this strain harbors various new viral species that show affinity to the distinctly established and proposed families Benyviridae, Endornaviridae, Fusariviridae, Hypoviridae, and Fusagraviridae. Moreover, some viral sequences that could not be assigned to any of the existing families or orders were also identified and showed similarities to the Alphavirus, Ourmiavirus, phlegivirus-like and Curvularia thermal tolerance virus-like groups. In addition, we also conducted deep sequencing analysis of small RNAs in the virus-infecting fugal strain. The results indicated that the Dicer-mediated gene silencing mechanism was present in S. rolfsii. This is the first report of viral diversity in a single S. rolfsii fungal strain, and the results presented herein might provide insight into the taxonomy and evolution of mycoviruses and be useful for the exploration of mycoviruses as biocontrol agents.
Managing Incompatible Impacts of Organizational Values on Knowledge Sharing

At any given time the two rival organizational values cooperation and competition coexist in any team and/or organization in different intensities and mix, depending on both internal factors (e.g., culture, task dimensions of accuracy and speed) and external factors (e.g., market and competitive forces). However, determining that desirable intensity and mix of these two values seems to be a challenging task in the current literature and no explicit method currently exists for measuring factors that may lead to determination of such desirable mix. Considering the crucial impacts of these values on organizational behaviours, this in turn may result in loss of efficiency and productivity in organizations. In this study a systematic review of current literatures in the areas of knowledge management, social psychology, organizational studies and Computer-Supported Cooperative Systems (CSCW) studies, is used to uncover a research theme for analysing the impacts of the two rival organizational values competition and cooperation on knowledge sharing behaviours through promotive interaction between individuals. Supporting the IT-culture conflict theory, this study is considered as a research theme which investigates the impact of culture on IT application and use. More specifically, by combining the goal interdependency theory of conflict , social learning theory, the internal organizational forces of competition and cooperation and the awareness net analysis, the present study deeply investigate the term tension between cooperative and competitive values and their impact on organizational behaviours. It then introduces factors that can assist in finding an optimal mix of the cooperative and competitive values in organizations at any given time. The present study also relates the above optimal mix/tension with the organization’s reward structure , the task dimensions of ‘speed’ and ‘accuracy’ , group characteristics and organizational climate in order to draw inferences for attaining an optimal level of process awareness for individuals while performing their tasks within an organization.
Mise en place d'un nouveau système d'obtention de viande d'impala au Zimbabwe : comparaison avec les systèmes existants : amélioration des conditions de production

Le Zimbabwe souffre de malnutrition et particulierement d'un manque de proteines animales. Pour contribuer a resoudre ce probleme, le CIRAD a developpe deux projets en association avec les collectivites locales qui utilisent la faune sauvage et particulierement l'impala (Aepyceros melampus) afin de fournir de la viande de brousse de bonne qualite sanitaire, vendue a un prix assez bas pour etre accessible a tout le monde. Ainsi, la viande d'impala est obtenue, soit par la chasse de troupeaux sauvages presents en abondance dans certaines zones, soit par leur elevage extensif au sein d'un ranch communal. L'analyse des performances de chasse au ranch a permis de montrer que la chasse de nuit etait pour le moment la meilleure technique mais qu'elle ne suffisait pas pour satisfaire pleinement les objectifs. La mise en place d'une boucherie fixe et de protocoles sanitaires ont permis d'executer toutes les etapes allant de l'abattage jusqu'a la vente dans le respect de l'hygiene. Toutefois, dans ces deux systemes, il a fallu s'adapter a la situation et aux besoins locaux. La comparaison de ces deux projets montre que le ranch permet un meilleur controle sanitaire de la viande et une meilleure gestion des troupeaux.
Weddings and Thai Women: The Construction of Weddings and the Portrayal of Thai Women Through Wedding Stories in Thai Wedding Magazines

Thai wedding magazines have been a primary resource for Thai women seeking wedding planning information. This study analyses the construction of weddings and investigates the portrayal of brides within the context of Thai wedding magazines by combining textual analysis and visual research methods. It investigates the social arrangements indicated in these magazines and the associated wedding ideology represented. Data for analysis is based on three magazines (Wedding Guru, We, and Love Wedding Magazine). There were twenty-two magazine issues and one MANUSYA: Journal of Humanities Regular 20.1, 2017 2 hundred and thirty-two stories in total, covering the period from November 2014 – October 2015. These magazines are targeted at women in their 20s and older. The study reveals how Thai wedding magazines formulate the meaning of weddings and the role of Thai wedding magazines in the transmission of particular ideas about desirable weddings in Thai society, while also reinforcing notions of what constitutes the ideal life for women. Findings in terms of the content indicate that weddings and women as brides in Thai wedding magazines are constructed only in positive ways. That is to say, weddings and the act of becoming a bride are constructed as examples of an already achieved ‘ideal’ life.
Prominencia H*: una muestra de español de Cuba

The dialectal variability of the toneme and the invariance of the pre-toneme (L*+H) are observed elsewhere, a general rule for Spanish dialects. With the aim of determine the tonal taxonomy, the pre-toneme invariance and the toneme variability, the speaker's tonal space is segmented in tonal micro-spaces according to psycho-phonetic thresholds, JND: 1.50 semitone. Two Cuban Spanish corpora are acoustically analyzed: one, read texts emitted by three male informants, and two, a broadcasting material produced by three male informants in a political debate, semi-spontaneous speech. The recorded material is segmented in intonational phrases, and paroxytone pitch accents are selected for analysis. The findings show a high degree of tonal variability in the pre-toneme (monotonal H* and H* in bi-tonal combinations) and certain invariance in the toneme. The findings are similar to the obtained in Buenos Aires, in Peninsular, and in Insular Spanish discourses and opposed to the obtained in laboratory corpora.
An Online Travelling Wave Fault Location Method for Unearthed-Operated High-Voltage Overhead Line Grids

In this paper, a single-ended travelling wave-based fault location algorithm is presented with reference to HV (i.e., 60 kV) overhead unearthed operated lines. The main novelty of this contribution lies in the method of calculating the speed of the earth mode component of the travelling wave, which exploits the earth mode impedance and capacitance, and of simplifying the fault location procedure. The developed procedure has been applied to a real double-circuit overhead line modeled by EMTP-rv, whereas the fault location algorithm has been implemented in a MATLAB environment. In order to validate the proposed method, a sensitivity analysis has been performed by varying the fault position, the fault resistance and the fault inception angle. The proposed approach has proven to be independent of all these parameters.
MADPTM: Mix zones and dynamic pseudonym trust management system for location privacy

In intelligent transportation systems, the messages transmitted and received from one vehicle to another vehicle may enhance location privacy scheme; falsification message forwarding collusion attack, timing, and transition attacks all are serious issues and must be addressed in event trust management. Without which, decision making on event message may endanger the whole transportation system and may even threat the human life. In addition, pseudonym expiry is another critical issue of location privacy. The time interval of decision waiting even has been the critical accident response time. In this paper, we proposed a new novel mix zones and dynamic pseudonym trust management system, called MADPTM, which aims to prevent against attackers under privacy‐enhanced road networks. On shortening the pseudonym expiry, we propose dynamic pseudonym trust management system, with the assistance of reported server. We performed a set of simulations under many trust attack models to evaluate the performance and efficiency of the proposed system. Our proposed MADPTM method proved to be highly resilient to various attacks, and simulation results verified that our method outperforms other existing methods.
Separación de carga en colisiones entre cristales de hielo y granizos esféricos

RESUMEN Mediciones experimentales de la corriente de cargado (CC) adquirida por un granizo esférico de 1cm de diámetro, creciendo por acreción de gotas de agua sobreenfriadas, debido a la acción del mecanismo de electrificación no-inductivo son presentadas en este trabajo. Las mediciones se llevaron a cabo en un rango de temperaturas de -7oC a -27oC y a valores de contenido efectivo de agua líquida (EW) y de velocidad de colisión (V) representativos de las condiciones de crecimiento seco del granizo. Se presenta un diagrama de signo de la CC en función de EW y de la temperatura ambiente. Se estimó una carga por colisión del orden de los fC. ABSTRACT Experimental measurements of the charging current (CC) on a spherical graupel of 1-cm diameter growing by accretion of supercooled droplets due to the non-inductive electrification mechanism are shown in the current work. The measurements were carried out at temperatures between -7oC and -27oC and for values of effective liquid water content (EW) and of collision velocities (V) representatives of dry growth regime of the graupel. Results are displayed in a charge sign diagram of a graupel as a function of ambient temperature and EW. A charge transfer per collision of a few fC was estimated.
Insulin Reduces Reaction of Follicular Granulosa Cells to FSH Stimulation in Women With Obesity-Related Infertility During IVF.

CONTEXT Women with obesity usually need larger doses of FSH for ovarian stimulation, resulting in poor outcomes; however, the mechanism is still unclear. OBJECTIVE To investigate the molecular regulation of FSH receptor (FSHR) expression associated with obesity. DESIGN Case-control study to improve in vitro fertilization (IVF) outcomes. PATIENTS Women with obesity (82) and women who were overweight (457) undergoing IVF and 1790 age-matched controls with normal weight from our reproductive medicine center. MAIN OUTCOME MEASURES FSHR expression was decreased in parallel with body mass index (BMI), whereas the estradiol (E2) level on the human chorionic gonadotropin (hCG) trigger day was significantly lower. RESULTS FSHR expression in human granulosa cells (hGCs), both mRNA (P = 0.02) and protein (P = 0.001) levels, was decreased in women who were overweight or obese. Both insulin (P < 0.001) and glucose (P = 0.0017) levels were positively correlated with BMI in fasting blood and follicle fluids (FFs) but not with FFs leptin level. We treated human granulosa-like tumor cells (KGN) cells with insulin; E2 production was compromised; the level of phosphorylated (p)-protein kinase B (p-Akt2) decreased, whereas p-glycogen synthase kinase 3 (GSK3) increased; and there were similar changes in hGCs from women with obesity. Stimulated hGCs from women with obesity with compound 21 (CP21), an inhibitor of GSK3β, resulted in upregulated β-catenin activation and increased FSHR expression. CP21 also increased the expression of insulin receptor substrate 1 and phosphatidylinositol 3-kinase (PI3K), as well as p-Akt2. CONCLUSIONS Women with obesity in IVF were associated with reduced FSHR expression and E2 production caused by a dysfunctional insulin pathway. Decreased FSHR expression in hGCs from women with obesity and insulin-treated KGN cells could be rescued by an inhibitor of GSK3β, which might be a potential target for the improvement of the impaired FSH-stimulation response in women with obesity.
Designing nearly tight window for improving time-frequency masking

Many audio signal processing methods are formulated in the time-frequency (T-F) domain which is obtained by the short-time Fourier transform (STFT). The properties of the STFT are fully characterized by window function, number of frequency channels, and time-shift. Thus, designing a better window is important for improving the performance of the processing especially when a less redundant T-F representation is desirable. While many window functions have been proposed in the literature, they are designed to have a good frequency response for analysis, which may not perform well in terms of signal processing. The window design must take the effect of the reconstruction (from the T-F domain into the time domain) into account for improving the performance. In this paper, an optimization-based design method of a nearly tight window is proposed to obtain a window performing well for the T-F domain signal processing.
