Optical-disk-based imaging system to be used as an optical microscope
Authors: Shima Takayuki , Fujimaki Makoto , Awazu Koichi 
Published: June 2016

Abstract
An optical disk surface is scanned spirally by laser light, as in the case of digital versatile discs, and a reflectance image is formed by rearranging the scanned intensity results. A prototype system is developed for imaging with a rotary encoder equipped to precisely control the disk rotation angle. We measured Escherichia coli dispersed on an optical disk sample surface and successfully obtained an image that is identical to that obtained using an optical microscope. The system is advantageous as an optical sensor for detecting sub-micrometer- to micrometer-order substances on a large-area surface.

Published: June 2016

Abstract
A two-dimensional simulation on a VHF H2 plasma (60 MHz) was performed using the plasma hybrid code, and plasma parameters were examined as a function of pressure for different discharge gaps. It was found that as the pressure increased, the H3
+ and H+ densities as well as the electron density had a maximum at a certain pressure, and the maximum shifted to high pressures as the discharge gap decreased. On the other hand, the H2
+ density decreased with the increase in pressure, independent of the discharge gap. The axial profiles of the H+, H2
+, and H3
+ densities showed that dominant ions were H3
+ in our pressure range.
Numerical study of breakdown pattern induced by an intense microwave under nitrogen and argon gases
Authors: Takahashi Masayuki , Ohnishi Naofumi 
Published: June 2016

Abstract
Filamentary plasma induced by microwave beam irradiation was reproduced in nitrogen and argon by combining fluid or particle plasma models with electromagnetic wave propagation. Transport coefficients used in the fluid model are estimated from particle simulation to maintain consistency of the breakdown structure between the fluid and particle models. A discrete structure was obtained using the one-dimensional (1D) fluid model, because a standing wave is generated in front of the plasma when the incident microwave beam is reflected by the overcritical plasma, which agrees with the breakdown structure obtained using the 1D particle model. A 2D plasma filament was also reproduced using the fluid model in nitrogen and argon. Reflection of the incident microwave in argon becomes stronger than that in nitrogen because of the denser argon plasma. Change in filament shape is induced in argon because the electric field is deformed at the plasma tip owing to stronger wave reflection from the neighboring filament. The propagation speed of the plasma front becomes larger in argon breakdown because of the larger ionization frequency and the larger diffusion coefficient.
Graphene on C-terminated face of 4H-SiC observed by noncontact scanning nonlinear dielectric potentiometry
Authors: Yamasue Kohei , Fukidome Hirokazu , Tashima Keiichiro , Suemitsu Maki , Cho Yasuo 
Published: June 2016

Abstract
We studied graphene synthesized on the C-terminated face (C-face) of a 4H-SiC substrate by noncontact scanning nonlinear dielectric potentiometry. As already reported by other researchers, multilayer graphene sheets with moiré patterns were observed in our sample, which indicates the existence of rotational disorder between adjacent layers. We found that the potentials of graphene on the C-face are almost neutral and significantly smaller than those observed on the Si-terminated face (Si-face). In addition, the neutrality of potentials is not affected by various topographic features underlying the multilayer graphene sheets. These results indicate that graphene on the C-face of SiC is decoupled or screened from the underlying structures and substrate, unlike graphene on the Si-face.

Published: June 2016

ObjectivesLearning ultrasound‐guided regional anesthesia skills, especially needle/ beam alignment, can be especially difficulty for trainees, who can often become frustrated. We hypothesized that teaching novices to orient the transducer and needle perpendicular to their shoulders will improve performance on a standardized task, compared to holding the transducer and needle parallel to the shoulders.MethodsThis study compared the effects of transducer orientation on trainees' ability to complete a standardized ultrasound‐guided nerve block simulation. The time to task completion and percentage of the attempt time without adequate needle visualization were measured. Participants were right‐handed healthy adults with no previous ultrasound experience and were randomly assigned to training in either transducer and needle alignment in a coronal plane, parallel to the shoulders (parallel group) or transducer and needle alignment in a sagittal plane, perpendicular to the shoulders (perpendicular group). Participants used ultrasound to direct a needle to 3 targets in a standardized gelatin phantom and repeated this task 3 times. Their efforts were timed and evaluated by an assessor, who was blinded to group assignment.ResultsData were analyzed on 28 participants. The perpendicular group was able to complete the task more quickly (P < .001) and with a smaller proportion of time lost to inadequate needle visualization (P < .001).ConclusionsUltrasound‐guided regional anesthesia trainees complete a standardized task more quickly and efficiently when instructed to hold the transducer and needle in an orientation perpendicular to their shoulders.

Published: June 2016

BackgroundOur objective was to assess the influence of shiftwork on change in endothelial function.MethodsThis longitudinal study was conducted in 188 police officers (78.2% men). Shiftwork status (day, afternoon, night) was assessed objectively using daily Buffalo, NY payroll work history records. Brachial artery flow‐mediated dilation (FMD) was assessed using ultrasound. Mean change in FMD% between 2004–2009 and 2010–2015 was compared across shiftwork using analysis of variance/covariance.ResultsOverall, mean FMD% decreased from 5.74 ± 2.83 to 3.88 ± 2.11 over an average of 7 years among all officers; P < 0.0001. Effect modification by gender was significant. Among men (but not women), those who worked day shifts had a smaller mean (±SE) decrease in FMD% (−0.89 ± 0.35) compared with those who worked the afternoon (−2.69 ± 0.39; P = 0.001) or night shifts (−2.31 ± 0.45; P = 0.020) after risk factor adjustment.ConclusionsLarger declines in endothelial function were observed among men who worked afternoon or night shifts. Further investigation is warranted. Am. J. Ind. Med. 59:1001–1008, 2016. Published 2016. This article is a U.S. Government work and is in the public domain in the USA

Published: June 2016

BackgroundWe aimed to determine the association between work, health, and lifestyle with regular use of pain medication due to musculoskeletal disorders in the general working population.MethodsCurrently employed wage earners (N = 10,024) replied to questions about health, work, and lifestyle. The odds for regularly using medication for musculoskeletal disorders were modeled using logistic regression controlled for various confounders.ResultsPain intensity increased the odds for using pain medication in a dose–response fashion. With seated work as reference, the odds for using pain medication were 1.26 (95%CI: 1.09–1.47) for workers engaged in standing or walking work that is not strenuous and 1.59 (95%CI: 1.39–1.82) for workers engaged in standing or walking work with lifting tasks or heavy and fast strenuous work.ConclusionsWorkers with higher levels of physical activity at work are more likely to use pain medication on a regular basis for musculoskeletal disorders, even when adjusting for pain intensity, lifestyle, and influence at work.

AbstractThe number of circulating tumor cells (CTCs) in blood is strongly correlated with the progress of metastatic cancer. Current methods to detect CTCs are based on immunostaining or discrimination of physical properties. Herein, a label‐free method is presented exploiting the abnormal metabolic behavior of cancer cells. A single‐cell analysis technique is used to measure the secretion of acid from individual living tumor cells compartmentalized in microfluidically prepared, monodisperse, picoliter (pL) droplets. As few as 10 tumor cells can be detected in a background of 200 000 white blood cells and proof‐of‐concept data is shown on the detection of CTCs in the blood of metastatic patients.
Rhodium‐Catalyzed Enantioselective Silylation of Cyclopropyl C−H Bonds
Authors: Lee Taegyo , Hartwig John F. 
Published: June 2016

AbstractHydrosilyl ethers, generated in situ by the dehydrogenative silylation of cyclopropylmethanols with diethylsilane, undergo asymmetric, intramolecular silylation of cyclopropyl C−H bonds in high yields and with high enantiomeric excesses in the presence of a rhodium catalyst derived from a rhodium precursor and the bisphosphine (S)‐DTBM‐SEGPHOS. The resulting enantioenriched oxasilolanes are suitable substrates for the Tamao–Fleming oxidation to form cyclopropanols with conservation of the ee value from the C−H silylation. Preliminary mechanistic data suggest that C−H cleavage is likely to be the turnover‐limiting and enantioselectivity‐determining step.

AbstractV‐shaped Tröger′s base core has been investigated as a central linking unit in the synthesis of new charge‐transporting materials for optoelectronic applications. The studied molecules have been synthesized in two steps from relatively inexpensive starting materials, and demonstrate high glass transition temperatures, good stability of the amorphous state, and comparatively high hole drift mobility (up to 0.011 cm2 V−1 s−1).
Melamine binding with arachidonic acid binding sites of albumin is a potential mechanism for melamine‐induced inflammation
Authors: Rajpoot Meenakshi , Bhattacharyya Rajasri , Banerjee Dibyajyoti , Sharma Anil 
Published: June 2016

AbstractMelamine adulteration of food is a public health concern. It has been seen that melamine causes disease in many organs. Melamine‐induced kidney disease is a well‐recognized clinicopathological entity. Inflammation is thought to be important in melamine‐induced pathology. Melamine is expected to bind with albumin because it has a positive charge. Albumin binds arachidonic acid. So if binding of melamine with albumin takes place, it has the potential to displace arachidonic acid from the albumin bound state. This phenomenon may be the source of mediators of inflammation in the melamine exposure state. This aspect is investigated in the present study by docking and molecular dynamics simulation. It is observed that melamine binds with some known arachidonic acid binding sites of albumin. This can lead to formation of more free arachidonic acid. It is also observed that melamine does not bind with extracellular signal regulated kinase 2 (ERK2). Therefore, the signal transduction mediated process involving ERK2 is not a likely mechanism of melamine‐induced inflammation. Therefore, we think that an increased free arachidonic acid level may contribute more to inflammation in the melamine exposure state.

AbstractMassivholzplatten erfahren eine vielfältige Verwendung im Bauwesen als tragendes und nichttragendes Konstruktionselement, aber auch als Gestaltungs‐ und Funktionselement. Grundgedanke der hier vorgestellten Untersuchungen war die Übernahme raumklimabeeinflussender Funktionen durch mehrlagige Massivholzplatten (SWP), indem Heiz‐ und Kühlelemente in die Mittellagen der Massivholzplatten eingebracht werden. Es wurden zunächst dreilagige Massivholzplatten mit unterschiedlichem Lagenaufbau hinsichtlich ihrer Biegefestigkeiten und ihrer Formstabilität im Differenzklima untersucht. Dabei zeigte sich gegenüber den Referenzmustern eine Abnahme der Biegefestigkeit und der Formstabilität. Weiterführende Untersuchungen zur Optimierung der Wärmeübertragung wurden mit Hilfe hygrothermischer Prüfungen vorgenommen. Im Ergebnis der ermittelten Aufheizkurven und Wärmestromdichten konnten Platten mit hoher Dichte in der Decklage bei spiralförmiger Verlegung der Verrohrung, einem Rohrabstand von 80 mm und einer Überdeckung von 4 mm als Optimum herausgearbeitet werden.Investigations on multi‐layer solid wood panels with heating and cooling elements. Multi‐layer solid wood panels are used in civil engineering as construction element as well as design‐ and functional element. The fundamental idea of this industry driven project was the integration of climatic‐control functions (cooling/heating) with fluid filled elements in multi‐layer solid wood panels. Solid wood panels with different design were tested on bending strength and dimensional stability under changing climatic conditions. They show, in relationship to a reference element, a degreasing of bending strength and dimensional stability. Further investigations on optimizing heat transfer were carried out with hygrothermal tests. An evaluation of heating curves shows that panels with high density top layer, and pipes designed in spiral curse, increase the heating performance. The optimal pipe dis‐tance was found to be 80 mm, with a covering layer of 4 mm thickness.

AbstractDie experimentelle Bewertung eines Stahlbetonbauteils mit der Gefahr eines möglichen spröden Schubversagens ist aufgrund der geringen Duktilität und damit Vorankündigung des Versagens bisher nicht durch die Richtlinie für Belas‐tungsversuche des DAfStb abgedeckt. Dieser Beitrag fasst die theoretischen und experimentellen Untersuchungen aus [1] zusammen, die durchgeführt wurden, um eine sichere experimentelle Tragsicherheitsbewertung bei vorwiegender Schubbeanspruchung zu ermöglichen. Um die spröden Versagensprozesse während des Versuchs zeitlich und räumlich besser auflösen zu können, wurde eine Kombination modernster Messverfahren eingesetzt. Es werden die Ergebnisse der experimentellen Untersuchungen berichtet und Empfehlungen für die experimentelle Versuchsdurchführung abgeleitet.Experimental Evaluation of the shear bearing safetyThe experimental evaluation of a reinforced concrete member with the danger of a brittle shear failure is yet not covered by the Guideline of the DAfStb for load testing because of the low ductile failure process. This paper describes the theoretical and experimental investigations carried out in [1] to allow a safe evaluation of the shear bearing safety in‐situ. For a high resolution of the beginning failure processes a combination of modern measuring techniques was applied. The results of the experimental investigations are shown and discussed. Finally advises are given for the experimental evaluation of the shear bearing safety during load testing of reinforced concrete members.

AbstractTigecycline (TGC) is an important antibiotic in treating various drug‐resistant bacteria. The dosage regimen for cerebral intraventricular TGC is still unknown. The aim of the study was to develop and validate liquid chromatography–tandem mass spectrometry (LC‐MS/MS) methods for the determination of TGC in human plasma and cerebrospinal fluid (CSF) to obtain an applicable regimen. The ion transitions under ESI positive model were performed at m/z 586.3 > 513.2 and m/z 595.3 > 514.3 for TGC and d9‐TGC internal standard (IS). For plasma and CSF samples, the calibration curve of TGC was linear within the ranges 25–2000 and 250–100,000 ng/mL; the IS normalized matrix effect was within the ranges 96.46–101.06% and 101.13–103.58%, respectively, for all. TGC was stable under all tested conditions. The patient received 1 mg intraventricular and 49 mg intravenous administration of TGC. The AUC0–12 in plasma and CSF calculated according to our noncompartment model were 4713 and 23,0238 h ng/mL, respectively. Given our findings cerebral intraventricular TGC may be a choice for clinicians to treat drug‐resistant Gram‐negative bacterial‐induced meningitis and the safety and efficacy of this administration route warrants further study.

AbstractAgents capable of eradicating bacterial biofilms are of great importance to human health as biofilm‐associated infections are tolerant to our current antibiotic therapies. We have recently discovered that halogenated quinoline (HQ) small molecules are: 1) capable of eradicating methicillin‐resistant Staphylococcus aureus (MRSA), methicillin‐resistant Staphylococcus epidermidis (MRSE) and vancomycin‐resistant Enterococcus faecium (VRE) biofilms, and 2) synthetic tuning of the 2‐position of the HQ scaffold has a significant impact on antibacterial and antibiofilm activities. Here, we report the chemical synthesis and biological evaluation of 39 HQ analogues that have a high degree of structural diversity at the 2‐position. We identified diverse analogues that are alkylated and aminated at the 2‐position of the HQ scaffold and demonstrate potent antibacterial (MIC≤0.39 μm) and biofilm eradication (MBEC 1.0–93.8 μm) activities against drug‐resistant Staphylococcus aureus, Staphylococcus epidermidis and Enterococcus faecium strains while demonstrating <5 % haemolysis activity against human red blood cells (RBCs) at 200 μm. In addition, these HQs demonstrated low cytotoxicity against HeLa cells. Halogenated quinolines are a promising class of antibiofilm agents against Gram‐positive pathogens that could lead to useful treatments against persistent bacterial infections.
