Acupuncture for Depression: A Critique of the Evidence Base
Authors: Schroer Sylvia , Adamson Joy 
Published: November 2010

SUMMARY Aim: The aim of this review is to examine the evidence for acupuncture's effectiveness as a depression intervention. Unlike other reviews, which consider methodological concerns relevant to all experimental evaluations, this review focuses on the scope of studies, and uses a PICO (patients, intervention, comparison, and outcome) structure to determine what can potentially be learned from primary studies that have already been screened for methodological quality by reviewers. Discussion: The review identified a number of study limitations. (i) Patients: majority of trial reports have not described a rationale for the selection of patients or inclusion/exclusion criteria. Prognostic indicators were not reported and there were also concerns about the generalizability of study populations. (ii) Intervention: most trials investigate poorly rationalized standardized acupuncture protocols thus quality of care may be an issue and generalizability to routine clinical practice is a main concern. In trials using other methods generalizability is also poor. (iii) Comparisons: concerns were raised about using therapeutically inappropriate acupuncture. (iv) Outcomes: short‐term focus and the narrow range of outcomes explored. According to more recent systematic review evidence it is probable the shortcomings identified in the PICO review have not been addressed by subsequent research. The concept of model validity, proposed by other researchers, is discussed, and suggestions put forward about complex intervention evaluation methods, which may be better suited to evaluating acupuncture care. Conclusion: Uncertainty remains about the value of acupuncture care, as it is routinely practiced in the West, and this uncertainty has not been resolved by trials to date. Existing evaluations may however be useful for guiding decisions about the value of specific techniques for patients with depression.

Background and purposeThe purpose of this study was to assess the initial post-market experience of the device and how it is compared with the Penumbra Pivotal trial used to support the 510k application.MethodsA retrospective case review of 157 consecutive patients treated with the Penumbra system at seven international centers was performed. Primary endpoints were revascularization of the target vessel (TIMI score of 2 or 3), good functional outcome as defined by a modified Rankin scale (mRS) score of ≤2 and incidence of procedural serious adverse events. Results were compared with those of the Penumbra pivotal trial.ResultsA total of 157 vessels were treated. Mean baseline values at enrollment were: age 65 years, NIHSS score 16. After use of the Penumbra system, 87% of the treated vessels were revascularized to TIMI 2 (54%) or 3 (33%) as compared with 82% reported in the Pivotal trial. Nine procedural serious adverse events were reported in 157 patients (5.7%). All-cause mortality was 20% (32/157), and 41% had a mRS of ≤2 at 90-day follow-up as compared with only 25% in the Pivotal trial. Patients who were successfully revascularized by the Penumbra system had significantly better outcomes than those who were not.ConclusionInitial post-market experience of the Penumbra system revealed that the revascularization rate and safety profile of the device are comparable to those reported in the Pivotal trial. However, the proportion of patients who had good functional outcome was higher than expected.

Published: November 2010

ObjectiveThe stent-assisted coiling technique has expanded the applicability of endovascular treatment for wide-neck intracranial aneurysms. However, the stability of the deployed stent has been questioned. We present this case to demonstrate intraprocedural migration of the deployed stent and subsequent management.Clinical presentationA 59-year-old female patient presented with dizziness and fatigue. Imaging, including CT and MR angiography, revealed a 7×6.5 mm wide-neck basilar tip aneurysm.InterventionStent-assisted coiling was attempted. After deployment of the stent, the distal portion of the stent migrated into the aneurysm sac, and then stabilized. Since attempted coiling without an assistance device was unsuccessful, the balloon-assisted coiling technique was applied. Near-total obliteration of the basilar tip aneurysm was accomplished.ConclusionThe stability of a deployed stent should be confirmed to exclude the possibility of intraprocedural stent migration. If stent migration into the target aneurysm occurs, the balloon-assisted coiling technique through the deployed stent is a feasible and valuable tool for successful coil embolization.

Abstract
Zinc and cadmium complexes of methyl 31-demethylbacteriopheophorbide-d18O-labeled specifically at the 131-oxo moiety were prepared. The FT-IR vibrational band of the 13-carbonyl group was shifted to a much lower wavenumber by their self-aggregation, similarly as in natural light-harvesting antennae.

Authors: Liu Shih-Hsien , Chen Fu-Shan , Lu Chung-Hsin 
Published: November 2010

Abstract
Thin CuInSe2 films were synthesized via selenizing Cu–In alloy-containing precursors. The alloy nanoparticles with CuIn and Cu2In were obtained via chemical reduction in ethylene glycol. Nanoparticles with a size around 40–60 nm were formed. The thin monophasic chalcopyrite CuInSe2 film with large grains was formed at 450 °C. Using the alloy nanoparticles for the coating process was demonstrated to be a potential way for preparing thin CuInSe2 films.

Published: November 2010

Abstract
Medication reactions, infectious etiologies, graft vs. host disease, serum sickness, and serum sickness-like reaction are the most common conditions that cause skin fever and rashes in immunosuppressed patients. In addition to this long list of diseases, severity of the primary disease and deterioration in the patient’s health status can make the diagnosis difficult. Furthermore, cutaneous and histological similarities in these mentioned conditions can be confounding. Here, we present a 16-year-old male patient with acute myeloid leukemia suffering from skin rashes and fever that appeared following a chemotherapy course leading to bone marrow suppression. We aim to discuss the differential diagnosis and share the diagnostic challenges that we already have experienced after immunoglobulin M-enriched polyclonal immunoglobulin.
Bestimmung des Nadelradius bei Tastschnittgeräten
Authors: Frühauf Joachim , Seifert Mario , Jeß Siegfried 
Published: November 2010

Zusammenfassung
Der vom Hersteller angegebene Nominalwert des Radius einer Tastnadelspitze weicht häufig stark vom tatsächlichen Radius ab. Für dessen Bestimmung eignet sich die Messung des Profils über eine scharfe Schneide (z. B. Rasierklinge). Bei der Auswertung dieses Profils wird der Abschnitt, der zur Radienbestimmung herangezogen wird, meist subjektiv festgelegt. Der Beitrag beschreibt eine Methode, die unter Einbezug der benachbarten geradlinigen Profilabschnitte (Konus der Nadel oder Flanken der Schneide) diesen Abschnitt auf iterativem Wege objektiv ermittelt und den Radius dafür bestimmt (Gauß-Kreis).

Authors: Ritterbusch Kai , Thurow Kerstin 
Published: November 2010

Zusammenfassung
Parallele Dosiervorgänge können in automatisierten Laboren nur schwer überwacht werden. Pipettoren benötigen beispielsweise spezielle Pipettenspitzen und elektrisch leitende Flüssigkeiten oder zusätzliche Ultraschallsensorik, die im Bewegungsbereich des Roboters untergebracht werden muss. In diesem Artikel wird eine Software vorgestellt, die es ermöglicht, mit Hilfe kommerziell erhältlicher optischer Systeme die parallele Dosierung von Mikrotiterplatten zu überwachen. Die Methode erreicht eine hohe Geschwindigkeit, ist platzsparend und wurde anhand umfangreicher Tests überprüft.

Zusammenfassung
Es wird ein neuartiger Kraft-Weg-Aufnehmer vorgestellt, welcher in Zukunft das dynamische Kalibrieren von Werkstoffprüfmaschinen ermöglicht. Das statische und dynamische Verhalten des Aufnehmers wurde untersucht und bewertet. Dabei wurden Messungen im Kraft- und Frequenzbereich bis 1,2 kN bzw. 1 kHz durchgeführt. Des Weiteren wurden die vorhandenen Kraftmesseinrichtungen dahingehend erweitert, dass eine gleichzeitige Kalibrierung der Kraft- sowie der Wegsensorik erfolgen kann. Dazu wurden Vorrichtungen konstruiert, welche das Kalibrieren der Wegsensorik mittels eines differenziellen Vibrometers ermöglichen.
Verwendung unterschiedlich abgestimmter faseroptischer Sensorelemente zur Neigungsbestimmung
Authors: Macheiner Klaus , Brunner Fritz K. 
Published: November 2010

Zusammenfassung
In der Messtechnik sowie im Bau- und Vermessungswesen ist die Bestimmung von Neigungswinkeln insbesondere bei kinematischen Anwendungen eine herausfordernde Aufgabe. Die Ursachen dafür sind einerseits das unvermeidliche verzögerte Ansprechen des Sensors und andererseits die Problematik der Trennung von Neigung und Beschleunigung. In dieser Arbeit wird versucht, mit Hilfe von verschieden abgestimmten Sensorelementen auf faseroptischer Basis, die als Pendel eingesetzt werden, einen Beitrag zur realistischen Bestimmung von Neigungswinkeln zu leisten. Neben dem Sensorelement an sich, dessen Eignung für die Neigungsmessung experimentell gezeigt wird, steht die Kombination verschiedener Sensorelemente und die damit verbundene Auswertung im Zentrum des Beitrags. Simulationen zeigen deutlich die Vorteile des vorgeschlagenen Konzepts und deuten auf weitere interessante Anwendungsmöglichkeiten hin.
NanoNi@C: Hochempfindliche Funktionsschicht für Druck- und Kraftsensoren
Authors: Koppert Ralf , Göttel Dirk , Schultes Günter , Werner Ulf 
Published: November 2010

Zusammenfassung
Die Arbeit beschreibt die Entwicklung eines neuen Materials, das auf eine mechanische Belastung zehnmal empfindlicher reagiert als die heute genutzten metallischen DMS-Materialen. In diesem Kompositmaterial liegen mit Kohlenstoff umhüllte Nickelcluster mit einem Durchmesser zwischen 10 nm und 20 nm vor. Die Umhüllungen bestehen aus einigen gebogen Graphenlagen, die die Nickelcluster wie Zwiebelschalen umgeben. Elektronenmikroskopische Aufnahmen zeigten, dass die Metallcluster isoliert voneinander vorliegen, sich also nicht berühren, so dass der Stromtransport durch die Hüllen aus Kohlenstoff beeinträchtigt ist. Wird nun eine Dehnung oder Verzerrung dieses komplexen Materials zB durch einen äußeren Druck hervorgerufen, so beeinflusst dies den Stromtransport durch das Material, also seinen elektrischen Widerstand, sehr stark. Dies ermöglicht eine sehr empfindliche elektrische Messung des Drucks oder der Kraft. Neben einer um den Faktor elf erhöhten Dehnungsempfindlichkeit (k-Faktor bis zu 22) im Gegensatz zu herkömmlichen DMS-Materialen weisen diese Dünnschichten einen auf null einstellbaren Temperaturkoeffizienten des elektrischen Widerstands auf (TKR kleiner als ±25 ppm/K). Erste Prototypen in Form von Stahlmembran-Drucksensoren zeigen eindrucksvoll das Potenzial dieser Dünnschichten für Sensoranwendungen auf. Die hohe Dehnungsempfindlichkeit konnte bestätigt werden, auch viele weitere Sensorparameter wie zB das Kriechen, die Linearität der Kennlinie und das Signalrauschen konnten untersucht werden und liegen in für diese Sensoren typischen Bereichen.
Early Marine Survival of Coho Salmon in the Strait of Georgia Declines to Very Low Levels

Abstract
The marine survival of juvenile coho salmon Oncorhynchus kisutch from the time they enter the Strait of Georgia in mid-May to the time of our trawl survey in mid-September declined from an average of about 15% in 1998 to approximately 1% in 2007. Early marine survival rates for juvenile coho salmon have been consistently low (&lt;5%) since 2002, and the rate of decline in early marine survival was greater for hatchery fish than for wild fish. This suggests that hatchery coho salmon are perhaps less able to survive than wild fish in the current marine ecosystem. The steady decline in total marine survival for coho salmon over the past four decades coincided with a warming of the Strait of Georgia, where both sea surface and sea bottom temperatures have increased by approximately 1°C since 1970. Another factor that appears to have contributed to the decline in early marine survival since the late 1990s is an increase in the number of days with an average sustained wind strength greater than 25 km/h. The linkage between wind strength and marine survival requires further study, but wind strength is known to affect the timing and level of primary productivity. The processes that caused the declining marine survival remain to be identified and may include factors associated with disease originating in both freshwater and salt water, metabolic stress, competition, and predation. The data suggest that coho salmon brood year strength is now mostly determined during the first 4 months spent in the Strait of Georgia. If the current low levels of marine survival continue, management initiatives to protect wild coho salmon will be urgently required, and it will be timely to critically evaluate the hatchery programs and policies.

Authors: Chang Chun-Shin , Bergeron Léonard , Chen Philip Kuo-Ting 
Published: November 2010

Background Late warping of dorsal cartilage onlay grafts is a problematic complication of current secondary rhinoplasty techniques in cleft lip patients. Material and Methods From May 2005 to December 2008, a total of 282 cleft patients had a secondary rhinoplasty performed at our center with a modified diced cartilage technique. Finely diced cartilage was injected over a cartilage framework, and no “sleeve” was used. Of those patients, 246 with a follow-up of more than 6 months were included in this retrospective study. Results The infection rate was 7.7%. In addition, 5.7% of patients complained of a bulbous tip. Cartilage warping, as seen with classic en bloc grafting of the dorsum, did not occur. Dorsal irregularity was seen in 8.5% of cases, and grafts were visible in 1.2% of cases. The reoperation rate was 8.1%. Conclusion This technique has greatly reduced the late cartilage warping seen with the classic cartilage bloc dorsal augmentation. Complications are low, comparable in occurrence to other techniques, and are easily manageable, making it our technique of choice.
Framework Geology, Petroleum Systems, and Play Concepts of the National Petroleum Reserve – Alaska
Authors: Bird Kenneth J. 
Published: November 2010

Abstract
The NPRA is a significant part of the north Alaskan petroleum province, a lightly explored region that is estimated to hold more than one-third of total U.S. undiscovered, technically recoverable, oil and natural gas resources based on the most recent U.S. Department of the Interior (USGS & MMS) estimates (Bird, 1999). The NPRA is a geologically complex region that includes prospective strata within passive margin, rift, and foreland basin sequences. Multiple source rock horizons have charged several regionally extensive petroleum systems. A variety of plays are present involving extensional and compressional structures and stratigraphic traps in shelf and turbidite systems.
Potential Reservoir Facies in the Nanushuk Formation (Albian-Cenomanian), Central North Slope, Alaska
Authors: LePain David L. , Kirkham Russell 
Published: November 2010

Abstract
The Albian-Cenomanian Nanushuk Formation is a thick regressive fluvialdeltaic-shelf succession that crops out in the foothills north of the Brooks Range and is present in the subsurface throughout most of the National Petroleum ReserveAlaska (NPRA). Three major facies assemblages are recognized in the Nanushuk Formation in outcrop at Rooftop Ridge and Ninuluk Bluff, and in the subsurface in the Grandstand, Square Lake 1, Wolf Creek 3, and Fish Creek 1 wells, including offshore, shoreface-delta-front, and bay fill assemblages. In the eastern NPRA and northern foothills belt, the shoreface-delta-front assemblage is the most common facies. Individual shoreface-delta-front deposits are arranged in coarsening-upward successions from 30 feet to over 100 feet thick that stack to form thicker regressive coarsening-upward successions bounded by distinct flooding surfaces. Sandstones of this assemblage are characterized by abundant storm wave-generated structures, suggesting that the shorezone in this area was significantly wave influenced, if not wave-dominated. Near the top of thicker regressive successions, shoreface-delta-front deposits lack appreciable mudstone and sandstones are amalgamated forming relatively thick bodies. Elements of the bay fill assemblage are present at the top of the Nanushuk Formation in outcrop at Ninuluk Bluff and in the subsurface in the Square Lake 1 well, where they are interpreted as an estuarine(?) complex. A possible sharp-based shoreface succession truncates the estuarine(?) complex at Ninuluk Bluff and is, itself, truncated by a major sequence-bounding unconformity at the base of the Seabee Formation (Turonian). This surface has also been recognized in the Square Lake 1 well and at Rooftop Ridge, demonstrating its regional extent.
Reservoir potential is greatest in the shoreface-delta-front assemblage where constant wave activity has winnowed fine-grained material and reduced the volume of ductile framework grains. Stacked amalgamated shoreface-delta-front sandstones in the Nanushuk Formation may form thick potential reservoir units. Possible shoreward pinchout in backshore and bay fill mudstones may provide opportunities for stratigraphic traps in the shoreface-delta-front assemblage. Thick sandstone accumulations in estuarine settings, such as recognized at Ninuluk Bluff, may represent secondary reservoir targets.
High Resolution Analysis of Petroleum Source Potential and Lithofacies of Lower Cretaceous Mudstone Core (Pebble Shale Unit and ?Grz of Hue Shale), Mikkelsen Bay State #1 Well, North Slope Alaska
Authors: Keller Margaret A. , Macquaker Joe H.S. 
Published: November 2010

Abstract
The Mikkelsen Bay State #1 well has one of the few completely cored Lower Cretaceous successions of the North Slope region between the NPRA and the ANWR. Forty-seven samples were collected over 30 m of section in this well to evaluate the variation in petroleum source potential and lithofacies, and to determine controls on their deposition. The sampled section includes the top Kemik Sandstone, the pebble shale unit, and possibly the basal Hue Shale (known as the gamma-ray zone or GRZ).
To determine lithofacies, unusually thin polished thin sections were prepared and analyzed using combined optical and backscattered electron imagery. The base of the studied succession, the upper part of the Kemik Sandstone, comprises medium to fine-grained sandstone and bioturbated muddy sandstones. These are abruptly overlain by burrow-mottled, thin (2-5 mm), relict-bedded, silt and pyrite-bearing clay and organic-rich (2-6% TOC) mudstones with rare “floating” sand grains (up to 500 microns) of the pebble shale unit and possibly basal Hue Shale. Lapilli tuffs begin to appear in the middle of the pebble shale, becoming more common near the top of the sampled core. Carbonate-dominated and clay-bearing pyrite-rich mudstones appear towards the top of the studied succession.
Forty-five samples were analyzed by Rock-Eval pyrolysis. These data can be divided into 3 units that are consistent with borehole geophysical log signatures and lithofacies. The lower unit, which is the upper part of the Kemik Sandstone, is a non-source interval that contains migrated hydrocarbons. The overlying mudstone succession comprises 2 distinct units which both contain primarily type II, oil-prone kerogens. The lower part of the pebble shale unit is just entering the oil window and hasn’t reached peak hydrocarbon generation, whereas the upper part of the pebble shale unit and possibly the lower part of the Hue Shale have generated hydrocarbons. The original S2, TOC, and HI values for this upper unit were probably closer to or greater than present values for the lower part of the pebble shale unit.
This high resolution study illustrates the dramatic variability in lithofacies and organic facies present over a short interval of the Lower Cretaceous mudstone succession of the North Slope. This variability is attributed to changes in sediment transport mechanisms (fluvial + storms versus ice-rafting); sediment provenance (detrital clay versus volcanic ash, and possibly north versus south source); position along the sediment transport path (silt to clay ratio); bottom water oxygen (episodically oxic versus anoxic); diagenesis; and organic productivity.
