Oligocene palynological succession from the East Java Sea
Authors: Lelono Eko Budi , Morley Robert J. 
Published: June 2011

Abstract
Rich palynomorph assemblages have been obtained through a marine Oligocene succession from the East Java Sea (Indonesia) and provide the first instance of an independently dated Oligocene succession from SE Asia that has yielded a good quality palynological record. The succession has been independently dated by nannofossils and foraminifera.
The palynomorph succession suggests climatic control on Oligocene vegetation, on which basis a regionally applicable zonation is proposed. The Early Oligocene is characterized by common rain forest elements, suggesting an everwet, rain forest climate. The early part of the Late Oligocene contains much reduced rain forest elements with grass pollen, indicating a more seasonal climate, whereas for the latest Late Oligocene, rain forest elements return in abundance, suggesting a superwet rain forest climate. This palynological succession is similar to that from the Sunda Basin in the West Java Sea, allowing the Sunda Basin succession to be dated by correlation.

The study also extends the stratigraphic range of
Dacrydium
and
Casuarina
, two plant taxa previously thought to have dispersed from the Australian Plate into SE Asia at the time of the collision with Sunda, to well before the time of collision. A different means of dispersal for these taxa is proposed.
Pre-Cenozoic sedimentary section and structure as reflected in the JavaSPAN
TM
crustal-scale PSDM seismic survey, and its implications regarding the basement terranes in the East Java Sea

Abstract
A new long-offset, long-record crustal-scale seismic survey of 9600 km called JavaSPAN was acquired in the Java Sea and Makassar Strait. The East Java Sea is underlain by continental basement with a prolonged multiphase history of deposition punctuated by extensional and compressional events. This East Java Terrane is a major component of SE Sundaland lying between the Meratus suture, the contemporary Java arc, and the west Sulawesi orogenic belt, but is poorly constrained on the north under the North Makassar Basin and in Kalimantan. A Precambrian to Permo-Triassic sedimentary section up to some 8.5 km in thickness overlies crystalline basement in a number of fault blocks and synformal structures below a strong angular unconformity. A thin overlap assemblage of Cretaceous to early Cenozoic sediments overlies that unconformity. Middle Eocene to Neogene clastic and carbonate rocks overlie another angular unconformity that marks the initiation of a well known history of Palaeogene extension, sag, and Neogene inversion. The East Java Terrane rifted from the Bonaparte-Arafura sector of northern Australia in the Jurassic and accreted onto a magmatic arc on the SW flank of what is now Kalimantan in the Cretaceous.
The Java convergent margin: structure, seismogenesis and subduction processes
Authors: Kopp Heidrun 
Published: June 2011

Abstract
The Java margin is characterized by a distinct variation in lower to upper plate material transfer and recurring catastrophic tsunamogenic earthquakes. Both processes are closely linked to the subduction of oceanic basement relief resulting in varying degrees of fore-arc deformation. Tomographic models of refraction seismic profiles and reflection seismic lines in combination with high-resolution multibeam bathymetric data reveal the variability in the deep structure and deformation of the Java fore-arc. Shallow subduction processes are governed by the sediment supply in the trench as well as by the nature and fabric of the oceanic lithosphere. The deep structure of the fore-arc reveals a shallow upper plate crust–mantle transition, present along the entire Java margin section. The serpentinized fore-arc mantle wedge governs the depth extent of the seismogenic zone here, which is narrower compared to its Sumatran analogue. In addition, offshore central Java, high relief oceanic basement features potentially act as asperities as well as barriers to seismic rupture, limiting the possible magnitude of subduction thrust earthquakes. However, the potential for geohazards, in particular tsunamis, is high along the entire margin. This results from tsunamogenic earthquakes, ubiquitous splay faults and potentially tsunamogenic landslides, which further increase the risk of future tsunamis.
Subducting slab structure below the eastern Sunda arc inferred from non-linear seismic tomographic imaging
Authors: Widiyantoro S. , Pesicek J. D. , Thurber C. H. 
Published: June 2011

Abstract
Detailed P-wave speed velocity structure beneath the Sunda arc has been successfully imaged by applying a non-linear approach to seismic tomography. Nearly one million compressional phases from events within the Indonesian region have been used. These include the surface-reflected depth phases pP and pwP in order to improve the sampling of the upper-mantle structure, particularly below the back-arc regions. We have combined a high-resolution regional inversion with a low-resolution global inversion to minimize the mapping of distant aspherical mantle structure into the study region. In this paper, we focus our discussion on the upper mantle structure beneath the eastern part of the Sunda arc. The tomographic images confirm previous observations of a hole in the subducted slab in the upper mantle beneath eastern Java. The images also suggest that a tear in the slab exists below the easternmost part of the Sunda arc, where the down-going slab is deflected in the mantle transition zone. In good agreement with previous studies, the properties of the deflected slab show a strong bulk-sound signature.

AbstractBoth the innate and adaptive immune systems contribute to tumor immunosurveillance in mice and humans; however, there is a paucity of direct evidence of a role for natural killer (NK) cells in this important process. In this study, we investigated the intratumoral phenotypic profile and functions of NK cells in primary human tumor specimens of non–small cell lung carcinoma (NSCLC). We used in situ methods to quantify and localize NK cells using the NKp46 marker and we characterized their phenotype in blood, tumoral, and nontumoral samples of NSCLC patients. Intratumoral NK cells displayed a profound and coordinated alteration of their phenotype, with a drastic reduction of NK cell receptor expression specifically detected in the tumoral region. According to their altered phenotype, intratumoral NK cells exhibited profound defects in the ability to activate degranulation and IFN-γ production. We found that the presence of NK cells did not impact the clinical outcome of patients with NSCLC. Finally, we showed that tumor cells heterogeneously express ligands for both activating and inhibitory NK receptors. Taken together, our results suggest that the NSCLC tumor microenvironment locally impairs NK cells, rendering them less tumorcidal and thereby supportive to cancer progression.

Published: June 2011

Background—
Limited information exists on the intermediate-term graft patency and 5-year clinical outcomes of patients receiving saphenous vein grafts with multiple (m-SVG) versus single distal targets (s-SVG) during coronary artery bypass graft (CABG) surgery in the current era.

Methods and Results—
We studied the association of the use of m-SVG versus s-SVG conduits with 1-year SVG failure (defined as ≥75% angiographic stenosis) and 5-year clinical events (death; death or myocardial infarction [MI]; and death, MI, or revascularization) in 3014 patients undergoing their first CABG surgery enrolled in the Project of Ex-vivo Vein Graft Engineering via Transfection (PREVENT) IV. Of 3014 patients enrolled in PREVENT IV, 1045 (34.7%) had ≥1 m-SVGs during CABG. Vein graft failure at 1-year was higher for m-SVG compared with s-SVG (adjusted odds ratio 1.24, 95% confidence interval 1.03 to 1.48). At 5 years, the adjusted composite of death, MI (including perioperative MI), or revascularization (hazard ratio 1.15, 95% confidence interval 1.00 to 1.31) and death or MI (hazard ratio 1.21, 95% confidence interval 1.03 to 1.43) were significantly higher in patients receiving m-SVGs.

Conclusions—
In patients undergoing first CABG surgery, the use of m-SVG was associated with a higher 1-year vein graft failure rate and trends toward worse clinical outcomes. Additional studies are needed to better understand the most appropriate conduit to improve long-term graft patency and clinical outcomes of patients undergoing CABG surgery. In the meantime, these data should encourage the use of s-SVG over m-SVG when feasible.

Published: June 2011

Background—

In the Platelet Inhibition and Patient Outcomes (PLATO) trial, a prespecified subgroup analysis showed a significant interaction between treatment and region (
P
=0.045), with less effect of ticagrelor in North America than in the rest of the world.

Methods and Results—
Reasons for the interaction were explored independently by 2 statistical groups. Systematic errors in trial conduct were investigated. Statistical approaches evaluated the likelihood of play of chance. Cox regression analyses were performed to quantify how much of the regional interaction could be explained by patient characteristics and concomitant treatments, including aspirin maintenance therapy. Landmark Cox regressions at 8 time points evaluated the association of selected factors, including aspirin dose, with outcomes by treatment. Systematic errors in trial conduct were ruled out. Given the large number of subgroup analyses performed and that a result numerically favoring clopidogrel in at least 1 of the 4 prespecified regions could occur with 32% probability, chance alone cannot be ruled out. More patients in the United States (53.6%) than in the rest of the world (1.7%) took a median aspirin dose ≥300 mg/d. Of 37 baseline and postrandomization factors explored, only aspirin dose explained a substantial fraction of the regional interaction. In adjusted analyses, both Cox regression with median maintenance dose and landmark techniques showed that, in patients taking low-dose maintenance aspirin, ticagrelor was associated with better outcomes compared with clopidogrel, with statistical superiority in the rest of the world and similar outcomes in the US cohort.

Conclusions—
The regional interaction could arise from chance alone. Results of 2 independently performed analyses identified an underlying statistical interaction with aspirin maintenance dose as a possible explanation for the regional difference. The lowest risk of cardiovascular death, myocardial infarction, or stroke with ticagrelor compared with clopidogrel is associated with a low maintenance dose of concomitant aspirin.

Assisting the Elderly in Remaining Politically Active: A Focus on Russia and its International Legal Obligations
Authors: Riekkinen Mariya 
Published: June 2011

AbstractThis article focuses on the potential of the elderly as a distinct social group capable of changing the direction of state policies. As far as the elderly have special rights and, also, expectations that these rights will be protected, they are capable of generating their own political preferences. In effect, they can be identified as a special group empowered to take part in the conduct of public affairs. It is a known fact that the political views of citizens are formulated long before individuals come to vote at polling stations. The author will examine which opportunities are provided for the elderly by the Russian state, so that these people can freely discuss public policies and remain politically active for an extended period of time.
These issues are dealt with in the context of Russian international legal obligations. This study is based on the praxis of international treaty-monitoring bodies. Russian statutory law and its application by courts and administrative organs are also explored.

Seasonal dynamics and overwintering strategy of the tachinid fly (Diptera: Tachinidae), Ormia ochracea (Bigot) in southern California
Authors: Paur Jennifer , Gray David 
Published: June 2011

AbstractWe present the first data on the seasonal abundance of an acoustically orienting parasitoid fly, Ormia ochracea (Bigot), in southern California. Peak population abundance of the parasitoid lags peak population abundance of its primary local host species the field cricket Gryllus lineaticeps Stål, by about six weeks. We also examined pupal diapause as a potential overwintering mechanism. Taken together our results suggest (1) that O. ochracea lacks a highly effective pupal diapause, (2) that spring adult field cricket species are safe from the fly, and (3) that most of the late fall flies die without reproducing.
Maria Sibylla Merian (1647-1717): an early investigator of parasitoids and phenotypic plasticity
Authors: Todd Kim 
Published: June 2011

AbstractIn a time when science and technology were almost exclusively dominated by men, the European naturalist and biological illustrator, Maria Sibylla Merian (1647-1717), studied arthropods, particularly American and European insects. rough careful observations, she documented and lavishly depicted phenomena that today we call parasitoidism and phenotypic plasticity, making her one of the first to inquire into these topics. Merian's legacy emphasizes the inextricable link between the environment and organisms.
Ants as biological control agents in agricultural cropping systems
Authors: Drummond Frank , Choate Beth 
Published: June 2011

AbstractAnts positively impact agricultural systems by rapidly consuming large numbers of pest insects, disturbing pests during feeding and oviposition, and increasing soil quality and nutrients. The ability of ants to control pest species has been recognized since the year 300 A.D. and farmers continue to conserve and promote ant populations in agricultural systems worldwide. Naturally occurring ant species in milpas, mango, citrus, coconut, cashews, and cotton control many pest insects. Through judicious insecticide application and changes in management practices such as tillage, and other manipulations of vegetation and crop structure, beneficial ant populations are conserved in a variety of agroecosystems. The first recorded example of biological control was the manipulation of ants throughout citrus orchards in Asia. Augmentation continues in citrus, and methods of ant introduction have been developed in Malaysian and Indonesian cocoa plantations, as well as to control sweet potato and banana weevils in Cuba. Ant species have been formally incorporated into other integrated pest management programs for cashew in Australia, cocoa in Papua New Guinea, and mango in Australia and Vietnam. With efforts to reduce chemical pesticide input in agricultural systems, research evaluating the ability of generalist ant species to control pest insects must continue.
Effect of Acetabular Labrum Tears on Hip Stability and Labral Strain in a Joint Compression Model
Authors: Smith Matthew V. , Panchal Hemang B. , Ruberte Thiele Ramon A. , Sekiya Jon K. 
Published: June 2011

Background Acetabular labrum tears are now commonly diagnosed in young and active patients. Because the role of the acetabular labrum is incompletely understood, it is critical to determine how these tears affect native hip biomechanics. Hypothesis Radial and circumferential labral tears significantly decrease hip stability and significantly alter strain patterns in the anterior and anterior-superior acetabular labrum. Study Design Controlled laboratory study. Methods Twenty-two human cadaveric hips without evidence of degeneration or dysplasia were assigned to a circumferential tear (n = 11) and a radial tear (n = 11) group. The hips were tested in a neutral position with an average compressive force of 25 N. In the circumferential tear group, the labral states were intact; 1-, 2-, and 3-cm circumferential tears; a 3-cm partial labrectomy; and a full labrectomy. In the radial tear group, the labral states were intact; a radial tear; a 1-, 2-, and 3-cm partial labrectomy; and a full labrectomy. The effect of labral injury on the stability ratio (peak dislocation force/compressive loads) and labral strain in the anterior and anterior-superior labrum was analyzed using repeated-measures analysis of variance. Results There was no significant difference in stability ratio after circumferential tears 3 cm or less in size compared with the intact labral state. Strain in the anterior and anterior-superior labrum was either unchanged or increased after circumferential labral tear. There was no significant difference in stability ratio after a radial tear or a 1-cm partial labrectomy compared with the intact labral state. A 2-cm partial labrectomy significantly decreased the stability ratio. Anterior and anterior-superior labral strain significantly decreased after a radial tear. Conclusion Under the influence of joint compression in a neutral hip position, the acetabular labrum continues to resist femoral head dislocation despite detachment from the acetabular rim. A radial tear in the acetabular labrum decreases adjacent labral strain, but removal of 2 cm or more of the acetabular labrum is needed before hip stability decreases. Clinical Relevance The findings suggest that the acetabular labrum continues to function to resist femoral head translation despite chondral-labral separation and that labral preservation, particularly with larger tears, may be important for maintaining hip stability. Further studies are needed to determine the effect of partial labral excision on the stability ratio with the hip in provocative positions such as extension, external rotation, and abduction.

Published: June 2011

Background Femoroacetabular impingement has become more widely recognized in the athletic patient population. The purpose of the present study was to review the clinical outcome after arthroscopic treatment of femoroacetabular impingement in a mixed population of high-level athletes. Hypothesis Arthroscopic treatment of femoroacetabular impingement results in significant improvement in clinical outcome and a high rate of return to play. Study Design Case series; Level of evidence, 4. Methods High-level athletes who underwent arthroscopic treatment of femoroacetabular impingement (rim trimming, labral refixation or debridement, femoral osteochondroplasty) with a minimum of 1-year follow-up were retrospectively identified. All patients completed hip-specific outcome scores (Modified Harris Hip Score [MHHS] and Hip Outcome Score [HOS]) at baseline and most recent follow-up. Results Forty-seven patients with an average age of 22.8 ± 6.2 years met the study criteria with a mean follow-up of 27.0 ± 5.5 months. Thirty-three patients (70.2%) were available for follow-up. The level of competition was 27.7% varsity high school, 53.2% college, and 19.1% professional athletes. There were statistically significant improvements in the mean MHHS score (preoperative, 68.6 ± 12.8; postoperative, 88.5 ± 17.7; P = .002) as well as the HOS score (preoperative, 78.8 ± 11.3; postoperative, 91.4 ± 14.0; P = .03). There was a significant improvement in the alpha angle, with 76.4° ± 14.5° preoperatively and 51.4° ± 11.7° postoperatively (P = .0003). Seventy-nine percent of patients were able to return to play after hip arthroscopy at a mean of 9.4 ± 4.7 months (range, 4-26 months); of those patients, 92.3% were able to return to the same level of competition. At 2-year follow-up, 73% of patients were able to return to play. Conclusion Arthroscopic treatment of femoroacetabular impingement in a mixed group of high-level athletes may result in a significant improvement in hip functional outcome: 78% of athletes were able to return to play at 1 year and 73% of athletes were able to play at 2-year follow-up.
