Abstract
Seitz, LB, Mina, MA, and Haff, GG. Postactivation potentiation of horizontal jump performance across multiple sets of a contrast protocol. J Strength Cond Res 30(10): 2733–2740, 2016—This study determined whether a postactivation potentiation (PAP) effect could be elicited across multiple sets of a contrast PAP protocol. Fourteen rugby league players performed a contrast PAP protocol comprising 4 sets of 2 paused box squats accommodated with bands alternated with 2 standing broad jumps. The rest period between the squats and the jumps and between the sets was 90 seconds. A control protocol with standing broad jumps only was performed on a separate session. A standing broad jump was performed ∼2 minutes before each protocol and served as a baseline measurement. Standing broad jump distance was significantly greater (4.0 ± 3.4% to 5.7 ± 4.7%) than baseline during the 4 sets of the contrast PAP protocol with the changes being medium in the first, second, and fourth sets (effect size [ES]: 0.58, 0.67, and 0.69, respectively) and large for the third set (ES: 0.81). Conversely, no PAP effect was observed in the control protocol. Additionally, the stronger players displayed a larger PAP effect during each of the 4 sets of the contrast PAP protocol (Cohen's d: 0.28–1.68) and a larger mean effect across these 4 sets (Cohen's d: 1.29). Horizontal jump performance is potentiated after only 90 seconds of rest after an accommodating exercise, and this PAP effect can be elicited across 4 sets. Additionally, the PAP response is largely mediated by the individual's strength level. These results are of great importance for coaches seeking to incorporate PAP complexes involving horizontal jumps in their training programs.

Inference and Analysis of Population Structure Using Genetic Data and Network Theory
Authors: Greenbaum Gili , Templeton Alan R , Bar-David Shirli 
Published: February 2016

AbstractClustering individuals to subpopulations based on genetic data has become commonplace in many genetic studies. Inference about population structure is most often done by applying model-based approaches, aided by visualization using distance-based approaches such as multidimensional scaling. While existing distance-based approaches suffer from a lack of statistical rigor, model-based approaches entail assumptions of prior conditions such as that the subpopulations are at Hardy-Weinberg equilibria. Here we present a distance-based approach for inference about population structure using genetic data by defining population structure using network theory terminology and methods. A network is constructed from a pairwise genetic-similarity matrix of all sampled individuals. The community partition, a partition of a network to dense subgraphs, is equated with population structure, a partition of the population to genetically related groups. Community-detection algorithms are used to partition the network into communities, interpreted as a partition of the population to subpopulations. The statistical significance of the structure can be estimated by using permutation tests to evaluate the significance of the partition’s modularity, a network theory measure indicating the quality of community partitions. To further characterize population structure, a new measure of the strength of association (SA) for an individual to its assigned community is presented. The strength of association distribution (SAD) of the communities is analyzed to provide additional population structure characteristics, such as the relative amount of gene flow experienced by the different subpopulations and identification of hybrid individuals. Human genetic data and simulations are used to demonstrate the applicability of the analyses. The approach presented here provides a novel, computationally efficient model-free method for inference about population structure that does not entail assumption of prior conditions. The method is implemented in the software NetStruct (available at https://giligreenbaum.wordpress.com/software/).
A General Approximation for the Dynamics of Quantitative Traits

Published: February 2016

AbstractSelection, mutation, and random drift affect the dynamics of allele frequencies and consequently of quantitative traits. While the macroscopic dynamics of quantitative traits can be measured, the underlying allele frequencies are typically unobserved. Can we understand how the macroscopic observables evolve without following these microscopic processes? This problem has been studied previously by analogy with statistical mechanics: the allele frequency distribution at each time point is approximated by the stationary form, which maximizes entropy. We explore the limitations of this method when mutation is small (4Nμ &lt; 1) so that populations are typically close to fixation, and we extend the theory in this regime to account for changes in mutation strength. We consider a single diallelic locus either under directional selection or with overdominance and then generalize to multiple unlinked biallelic loci with unequal effects. We find that the maximum-entropy approximation is remarkably accurate, even when mutation and selection change rapidly.

TEMA 15-2015: Beneficios de la colostomía en la calidad de vida del paciente con lesión medular crónica y ventajas de su realización por vía laparoscópica

Published: February 2016

<p>Las investigaciones recientes sugieren que el manejo de los problemas intestinales es una fuente importante de preocupación para los pacientes con lesión medular y puede alterar significativamente la calidad de vida. Los síntomas gastrointestinales más comunes hallados fueron estreñimiento e incontinencia fecal, reportado por 46% y 41%, respectivamente. Distensión abdominal se reportó en un 22% y el dolor gastrointestinal (dolor abdominal, rectal o anal) fue reportado por 33% de los pacientes. No es sorprendente que los síntomas gastrointestinales estén asociados con depresión, ansiedad, y deficiencias significativas en la calidad de vida en una parte significativa de las personas con lesión de médula espinal. Dada la gravedad de estos síntomas, varios autores han argumentado que las opciones quirúrgicas invasivas, incluyendo derivaciones intestinales (colostomía o ileostomía) o la creación de un Enema Anterógrado Continente de Malone (MACE), pueden proporcionar resultados superiores para determinados pacientes con disfunción intestinal neurogénica severa después de la lesión médular. Las ventajas de la colostomía laparoscópica resaltan, particularmente, la posibilidad de evitar una laparotomía amplia con todos sus riesgos. Algunos autores reportan menor formación de adherencias después de la laparoscopia lo que reduce riesgo de obstrucción y facilita la reconstrucción del tránsito en las colostomías temporales. La ventaja indiscutible es el acceso miniinvasivo a los pacientes.</p>

Published: February 2016

Background: Human periodontal ligament stem cells (hPDLSCs) are readily accessible and represent a promising source of mesenchymal stem cells (MSCs) for therapies. For expected clinical applications of stem cell therapies, prolonged maintenance of stemness of hPDLSCs after storage is crucial. Likewise, optimization of cell quality and standardization of manufacturing protocols require evaluation of hPDLSC characteristics after storage. The aim of this study is to evaluate maintenance of stemness of hPDLSCs isolated after prolonged storage of the periodontal ligament (PDL), by studying: 1) growth and proliferation; 2) immunophenotypes; and 3) differentiation capabilities of hPDLSCs.Methods: After extraction of premolars (N = 10), hPDLSCs were isolated immediately (n = 5) or after 1 week of tooth storage in growth medium (n = 5). Both groups were evaluated for: 1) colony formation; 2) proliferation; and 3) immunophenotypes. Osteogenic, adipogenic, and chondrogenic differentiation capabilities of hPDLSCs were evaluated at different times and by real‐time polymerase chain reaction (PCR).Results: Storing PDLs attached to teeth did not affect stemness of hPDLSCs. Colony formation and proliferation properties of hPDLSCs from PDLs harvested immediately after extraction or after storage for 1 week were comparable, and there were no significant differences in immunophenotypic markers between the two groups. Osteogenic, adipogenic, and chondrogenic differentiation capabilities of hPDLSCs were unaltered after PDL storage. Real‐time PCR analyses indicated that the expression of: 1) osteogenic (runt‐related transcription factor 2, alkaline phosphatase, and osteocalcin); 2) adipogenic (peroxisome proliferator‐activated receptor‐γ and lipoprotein lipase); and 3) chondrogenic (aggrecan, collagen Type 2, and collagen Type 10) differentiation markers were similar for both groups.Conclusion: Within the limitations of the study, hPDLSCs stored for 1 week maintain the important characteristics of MSCs.

Asumir esta mirada narrativa, transitada hace décadas pero nunca totalmente instalada en la enseñanza de la Historia, nos permite generar prácticas de aprendizaje significativas que interpelen a los estudiantes además de articular con discursos, literarios, cinematográficos, televisivos, de amplia circulación y potencia. De este modo, el presente artículo tiene como fin, revisitar y dar a conocer mi investigación y propuesta de trabajo para la enseñanza de la historia en el nivel secundario desde un enfoque narrativo.
Increasing Benzodiazepine Prescriptions and Overdose Mortality in the United States, 1996–2013
Authors: Bachhuber Marcus A. , Hennessy Sean , Cunningham Chinazo O. , Starrels Joanna L.

Objectives. To describe trends in benzodiazepine prescriptions and overdose mortality involving benzodiazepines among US adults. Methods. We examined data from the Medical Expenditure Panel Survey and multiple-cause-of-death data from the Centers for Disease Control and Prevention. Results. Between 1996 and 2013, the percentage of adults filling a benzodiazepine prescription increased from 4.1% (95% confidence interval [CI] = 3.8%, 4.5%) to 5.6% (95% CI = 5.2%, 6.1%), with an annual percent change of 2.5% (95% CI = 2.1%, 3.0%). The quantity of benzodiazepines filled increased from 1.1 (95% CI = 0.9, 1.2) to 3.6 (95% CI = 3.0, 4.2) kilogram lorazepam equivalents per 100 000 adults (annual percent change = 9.0%; 95% CI = 7.6%, 10.3%). The overdose death rate increased from 0.58 (95% CI = 0.55, 0.62) to 3.07 (95% CI = 2.99, 3.14) per 100 000 adults, with a plateau seen after 2010. Conclusions. Benzodiazepine prescriptions and overdose mortality have increased considerably. Fatal overdoses involving benzodiazepines have plateaued overall; however, no evidence of decreases was found in any group. Interventions to reduce the use of benzodiazepines or improve their safety are needed.
Comments: Macondo 5 Years Later
Authors: Donnelly John 
Published: February 2016

Editor's column
The Macondo explosion and oil spill occurred 5 years ago this month, freezing activity in the US Gulf of Mexico and putting the industry in a negative spotlight for weeks. But, in addition to drawn-out legal consequences, the accident spawned new technology, improved safety practices, and better operations awareness. Some of the improvements are still a work in progress.
On 20 April 2010, a blowout and explosion on the Deepwater Horizon rig on the Macondo prospect in the deepwater US Gulf of Mexico killed 11 crewmen. On 22 April, the rig sank, leaving the well gushing and causing the largest oil spill in US waters. The spill continued until 15 July when it was finally capped, and relief wells permanently sealed the well.
Five years later, the impact of the disaster is clearer. Despite fears from some in the oil and gas industry, the accident and resulting regulation did not greatly harm US offshore oil output. The government temporarily stopped drilling in the US Gulf but operators were able to obtain new drilling permits within a year. Now, several large new oil projects are on the horizon, including ones by Shell, ExxonMobil, Hess, and Chevron. The new projects, with a potential to produce close to 1 million B/D, promise to return the Gulf into a major source of US production, although the greatest threat now is not regulation stemming from the oil spill but from the recent steep drop in oil prices. In 2001, the Gulf of Mexico accounted for a fourth of US oil output, but production has dropped since then because of well decline and the drop in permits issued after Macondo. With the recent dramatic rise in onshore unconventional output in the US, the Gulf now accounts for only about 10% of US oil production.
But Macondo did hurt the industry’s reputation—the oil spill dominated news headlines for weeks. The recent concern about the safety of hydraulic fracturing operations and crude oil transport by pipeline or railcar stem in part from the fallout of the Macondo disaster. All of this plays into the industry’s “license to operate” in communities around the globe. Any dramatic, high news impact industry incident— upstream or downstream—heightens public awareness about industry operations and their potential impact.
The industry has, in fact, improved operations since Macondo: new technologies have been developed to prevent and arrest blowouts and spills, and the industry has improved engagement with the public. The Macondo incident has also transformed risk management in offshore operations, although there is still work to be done, according to DNV GL. The consultancy maintains that there are still lessons to be learned from Macondo; for one thing, companies are tempted to skirt long-term management of risk for shorter-term decisions about profitability. The worry is that sharply lower oil prices will lead to cost cutting and neglecting safety ideas, which will make the industry even more vulnerable when the next Macondo comes around. JPT
Dual-Drillpipe Method Shows Success in PMCD Wells With Cuttings Return
Authors: Aleksandersen Jostein , Vestavik Ola M. 
Published: February 2016

Technology Update
The Reelwell Drilling Method (RDM) is a new technology developed to solve certain drilling problems and improve the operation margin for various applications.
The technology uses a specially designed dual drillpipe (DDP), shown in Fig. 1, that has two flow channels, one for the flow of drilling fluid into the well down to the bit and the other for the return flow of fluid from the bottom of the well back to the surface.
Developed in Norway, the RDM has been field tested at various locations in the past several years. The technology has features for pressurized mud cap drilling (PMCD), managed pressure drilling (MPD), and extended reach drilling (ERD). The RDM enables
PMCD with cuttings return
MPD with a constant well pressure profile
ERD with reduced torque and drag, no equivalent circulating density (ECD) in the wellbore, and no cuttings in the hole
The DDP is available in 6?-in. steel and 5?-in. to 7½-in. aluminum pipe diameters. With a pressure rating of 5,000 psi, the DDP contains a concentric inner pipe with a stab-in connector and is handled in the same way as a conventional drillpipe.
The RDM can be adapted to a standard drilling rig, with the following tools and arrangements:
A top drive adapter—a swivel directing the fluid return through a second standpipe and mud hose
An inner pipe valve—a bottomhole assembly (BHA) tool for the isolation of the drillstring during connections
A flow control unit—a skid with a control valve system for flow and pressure control
A rotary control device—a standard tool at the blowout preventer for MPD The RDM uses standard BHA components and drill bits, and the tools operate on reduced flow rates.
