Analysis of factors associated with maintenance discontinuation in implant patients (2015)

Maintenance following implant treatment is essential to ensure long-term stability. Accordingly, the objective of this study was to investigate the factors leading patients to discontinue maintenance following implant treatment. Among the 729 patients that underwent implantation at the Department of Oral Implantology, Osaka Dental University Hospital from January 2008 to December 2012, 41 patients were excluded from the study. Exclusion criteria comprised patients without a superstructure attachment, those who only underwent maxillary sinus floor augmentation procedures and those who discontinued visiting the hospital prior to superstructure attachment. Treatment was discontinued in 181 patients. The rate of discontinuation was 26.6 %. The odds ratio (OR) in the adjustment model was 1.552 (95 % CI 1.078-2.236) in males when compared with females. When compared with those who were 30-64 years old, the OR was 5.818 (95 % CI 3.017-11.220) in those 29 years old or younger and 1.561 (95 % CI 1.021-2.386) in those 65 years old or older. Moreover, when compared with those with a O'Leary's Plaque Control Record of all teeth and superstructures (PCR) level of 20 % or less following superstructure attachment, the OR was 2.113 (95 % CI 1.471-3.035) in those with a PCR level of 20 % or more following superstructure attachment. It is highly important to decrease maintenance discontinuation, especially in patients aged 29 years old or younger with a PCR level of 20 % or more following superstructure attachment. Moreover, a support system must be developed to enable patients with difficulties visiting the hospital to continue their maintenance program.
Wideband Antennas for Microwave Brain Stroke Imaging (2018)

In this paper, a monopole antenna designed to operate in a matching medium is described. The dimensions of the antenna is optimized with Multi-Objective Particle Swarm Optimization (MOPSO) to obtain the desired reflection coefficient and gain characteristics. All simulations are performed with HFSS in an automated manner by the PSO algorithm via Matlab. The reflection coefficient of the antenna is tested by embedding it to the characterized matching medium. The dielectric properties of the medium is verified with the well known open ended coaxial probe measurement technique. The antenna will be tested with a phantom material mimicking the brain tissues and the results of the microwave imagine algorithm will be presented.
Internalized plans for communication-sensitive robot team behaviors (2004)

Autonomous teams of robots operating in a dynamic, adversarial environment stand to benefit from using all available resources. But how can knowledge be used to construct a plan that does not interfere with the robots ability to react to its environment? In this research we distill abstract representation into a plan usable by a reactive behavior-based architecture. This plan is then exploited to enhance the performance of a team of robots tasked with maintaining communications while performing reconnaissance. Utilizing multiple plans in serial and in parallel is shown via simulation to be a promising method for increasing mission performance. We conclude that the utility of these internalized plans warrants further investigation as a method for imbuing reactive agents with a priori knowledge.

Human ASH-1 Promotes Neuroendocrine Differentiation in Androgen Deprivation Conditions and Interferes With Androgen Responsiveness in Prostate Cancer Cells (2013)

In summary, the present data support previous evidence that the acquisition of a neuroendocrine phenotype is linked to androgen responsiveness profiles and suggest a pivotal role of hASH-1 transcription factor, whose activity might be explored as a potential therapeutic target in prostate cancer, with special reference to hormone refractory disease.
Noncontact atomic force microscopy study of the spinel MgAl<sub>2</sub>O<sub>4</sub>(111) surface (2012)

Based on high-resolution noncontact atomic force microscopy (NC-AFM) experiments we reveal a detailed structural model of the polar (111) surface of the insulating ternary metal oxide, MgAl(2)O(4) (spinel). NC-AFM images reveal a 6√3×6√3R30° superstructure on the surface consisting of patches with the original oxygen-terminated MgAl(2)O(4)(111) surface interrupted by oxygen-deficient areas. These observations are in accordance with previous theoretical studies, which predict that the polarity of the surface can be compensated by removal of a certain fraction of oxygen atoms. However, instead of isolated O vacancies, it is observed that O is removed in a distinct pattern of line vacancies reflected by the underlying lattice structure. Consequently, by the creation of triangular patches in a 6√3×6√3R30° superstructure, the polar-stabilization requirements are met.
The Size and Shape of the Optic Disc in Normal Human Eyes (1990)

We studied the size, shape, and configuration of connective tissue of the optic disc in normal eye-bank eyes from 60 adults. The mean vertical and horizontal disc diameters were 1.88 and 1.77 mm, respectively. These figures are larger than most estimates of disc diameter using clinical image analysis methods. Within our sample, larger eyes did not have larger discs. The normal variation in disc diameter is sufficient to explain the normal variation in cup-disc ratio. The optic discs of blacks were larger and more oval than those of whites, though the axial lengths of the eyes in the two groups were not significantly different. Women's eyes and discs were smaller than those of men, possibly explaining the smaller cup-disc ratio in women. Larger optic discs and optic nerves have more optic nerve fibers than do smaller discs and nerves. Oblique insertions of the disc were detected in 18% of eyes. These were predominantly centered in the inferior disc and were more commin in white women.
Application of top surface imaging process to 157-nm lithography (2001)

A top surface imaging (TSI) process with a very thin imaging resist is one of the approaches for 100-nm or smaller pattern fabrication. We have been evaluating the different types of bilayer silylation processes for 193nm lithography, such as the bilayer silylation process without applying any wet-development and an improved bilayer silylation process that applies the vapor phase silylation treatment after alkaline wet-development of the top layer (SILYAL). We have been trying to apply these TSI processes to 157nm lithography and could successfully fabricate sub-100-nm fine resist patterns with high aspect ratios. We confirmed the lithographic high performance of these bilayer silylation processes and 157-nm lithography. In this paper, we describe the current status and progress in these silylation processes for 157nm lithography.

Lasso the power of the Internet. (1997)

News about the Internet is everywhere. The reality, however, is that the Internet is neither a passing fad nor a false alarm. It is a dynamic new way for healthcare organizations to disseminate and retrieve information, conduct market research, communicate with broad provider networks, educate consumers and sell products and services.
Studies on the Protease of Pseudomonas (1960)

The extracellular proteinase of Ps. myxogenes sp. is constitued with Ca as an essential component as shown in the previous paper1). This paper deals with a study concerning the step of incorporation of Ca in the synthesizing reaction of the proteinase of the bacteria. A protein or peptide substance constituted from Ca is not found within the cells of the bacteria which have been shaken in the presence of a carbon source and Ca ion, while the proteinase is accumulated at the extracellular site. As it is sure that nitrogen material within the cells (which has been assumed to be a more complicated substance than amino acid, which is a precursor substance) contributes to the enzyme synthesis, the above result might suggest that Ca is not incorporated at the precursor state in the enzyme synthesis, or even if the incorporation really does occur at that state, the precursor substance is immediately secreted in the medium. However, we have not found the precursor material which is secreted in the medium where the material is activated auto-catalytically as seen in Streptococcal proteinase6). Accordingly, it is difficult to consider the latter case to occur. The total amount of organic nitrogen material secreted in the medium containing a carbon source by shaking the bacterial cells aerobically, is found to be identical in both the presence or absence of Ca ion, but the secreted protein content is remarkably diminished (to almost one-fifth) in the absence of Ca ion. Further, it is clear that the removal of Ca from the enzyme molecule, by treatment with EDTA at 50°C, results not only in inactivation of the enzymatic action but also exhibits the autosplitting phenomenon of the enzyme protein. These results may lead to the assumption that Ca-free proteinase would be secreted in the medium regardless of the existence of Ca ion, and the enzyme is accumulated when it is stabilized by the constitution of Ca ion in the medium, whereas the auto-splitting phenomenon of the enzyme would take place in absence of the Ca ion. Therefore, the incorporation of Ca in the proteinase synthesis by the bacteria is considered to occur in the completely synthesized Ca-free proteinase secreted in the medium. The author wishes to express his sincere thanks to Prof. H. Katagiri of Kyoto University for his constant guidance and encouragement throughout this work. Thanks are also due to Mr. E. Masuo of this Laboratory for his assistance.
A digitally controlled 5GHz analog phase interpolator with 10GHz LC PLL (2007)

This paper describes a 5GHz Analog Phase Interpolator (API) for clock synthesis and clock data recovery dedicated to multi-gigabit/s serial link applications. The system includes a 10GHz LC Phase Locked Loop for clock generation and an Analog Phase Interpolator implemented with Current Mode Logic (CML) offering better phase noise and speed performances compared to CMOS logic. It has been implemented in ST’s 65nm RfCMOS technology. The core of the API occupies a silicon area of 0.09x 0.17mm2 and dissipates less than 22.56mW from a 1.2V voltage supply.
A high throughput architecture for the H.264/AVC CAVLC encoder (2012)

One of the encoding methods offered by H.264/AVC is context-based adaptive variable length coding (CAVLC). This paper presents a high throughput hardware implementation of the CAVLC encoder. A dual coefficient scanning phase is investigated and modified to improve the speed of the encoding phase. This improved scanning solution determines all the required data for the encoding phase to be completed in a minimized and constant number of clock cycles. The modified scanning phase approach offers significant throughput capabilities for CAVLC: At 200 MHz, the architecture is capable of encoding 1080p video files at 86 fps.
Anopheline salivary protein genes and gene families: an evolutionary overview after the whole genome sequence of sixteen Anopheles species (2017)

We provide here a comprehensive description, classification and evolutionary overview of the main anopheline salivary protein families and identify two novel candidate markers of human exposure to malaria vectors worldwide. This anopheline sialome catalogue, which is easily accessible as hyperlinked spreadsheet, is expected to be useful to the vector biology community and to improve the capacity to gain a deeper understanding of mosquito salivary proteins facilitating their possible exploitation for epidemiological and/or pathogen-vector-host interaction studies.
Effect of Asbestos on the Metabolism of Vasoactive Substances in Isolated Perfused Guinea Pig Lungs (1983)

The measurement of pulmonary metabolism of three vasoactive substances and quantitative assessment of changes in lung morphology were performed in a long-term study of asbestos-exposed guinea pigs. Animals received intratracheal injections of a single dose of a sterile suspension of Canadian chrysotile B (5 mg), while control animals received only saline. Six months after the treatment, the guinea pigs were sacrificed, the lungs removed, perfused via the pulmonary artery and the metabolism of vasoactive substances was assessed (in vitro) in a cascade superfusion system. At the end of the experiments, the lungs were fixed in a glutaraldehyde solution for microscopic examination. The tissue response consisted of both inflammatory reaction of terminal and respiratory bronchioles and diffuse alveolar septal infiltration with interstitial fibrosis. The reaction was characterized at six months by a progressive bronchiolitis obliterans with fibroblastic proliferation and collagen formation. The development of the disease did not cause significant changes in the metabolism of acetylcholine and bradykinin. However, the metabolism of prostaglandin E2 decreased with the appearance of the bronchiolitis obliterans. Our results showed that asbestos exposure may produce early biochemical changes resulting in altered lung metabolism of vasoactive substances; these modifications could contribute to the pathogenesis of asbestosis.
Loss of Somatostatin Receptor Subtype 2 in Prostate Cancer Is Linked to an Aggressive Cancer Phenotype, High Tumor Cell Proliferation and Predicts Early Metastatic and Biochemical Relapse (2014)

Somatostatin receptor subtype 2 (SSTR2) is the most frequently expressed SSTR subtype in normal human tissues. SSTR2 expression is differentially regulated in various tumor types and therapeutic somatostatin analogs binding to SSTR2 are in clinical use. In prostate cancers highly contradictory results in terms of SSTR2 expression and its consequences have been published over the past years. The aim of this study was to clarify prevalence and clinical significance of SSTR2 expression in prostate cancer. Therefore, quantitative immunohistochemistry (IHC) using a tissue microarray containing samples from 3,261 prostate cancer patients with extensive clinical and molecular cancer characteristics and oncological follow-up data was performed. IHC data was compared to publicly available Gene Expression Omnibus datasets of human prostate cancer gene expression arrays. While membranous SSTR2 staining was always seen in normal prostate epithelium, SSTR2 staining was absent in more than half (56.1%) of 2,195 interpretable prostate cancer samples. About 13% of all analyzed prostate cancers showed moderate to strong cytoplasmic and membranous SSTR2 staining. Staining intensities were inversely correlated with high Gleason grade, advanced pT category, high tumor cell proliferation (p<0.0001 each), high pre-operative PSA levels, (p = 0.0011) and positive surgical margins (p = 0.006). In silico analysis confirmed lower SSTR2 gene expression in prostate cancers vs. normal adjacent tissue (p = 0.0424), prostate cancer metastases vs. primary cancers (p = 0.0011) and recurrent vs. non-recurrent prostate cancers (p = 0.0438). PSA-free survival gradually declined with SSTR2 staining intensity (p<0.0001). SSTR2-negative cancers were more likely to develop metastases over time (p<0.05). In conclusion, most prostate cancers are indeed SSTR2-negative and loss of SSTR2 strongly predicts an unfavorable tumor phenotype and poor prognosis. Therefore, SSTR2 expression seems an important factor in the pathogenesis of prostate cancer and re-introduction of the receptor in SSTR2-negative prostate cancers may feature a promising target for novel gene therapy approaches.
O<sub>2</sub>availability modulates transmembrane Ca<sup>2+</sup>flux via second-messenger pathways in anoxia-tolerant hepatocytes (1997)

Transmembrane Ca(2+)-flux was studied from single isolated turtle hepatocytes by using a noninvasive Ca(2+)-selective self-referencing microelectrode. Cells in Ca(2+)-reduced culture medium demonstrated a vanadate- and lanthanum-inhibitable Ca(2+)-efflux of 4 x 10(-17) mol Ca2+. microns-2. s-1 continuously over 170 h. This flux diminished with 50 nM phorbol 12-myristate 13-acetate, a protein kinase C (PKC) activator, and was reinstated on PKC deactivation with sphingosine. Progressive hypoxia resulted in a reversible suppression of Ca2+ efflux to 90% of normoxic controls with an apparent Michaelis constant for oxygen of 145 microM. PKC activation was critical in this suppression, as anaerobic administration of sphingosine caused a Ca2+ influx and cell rupture. Hypoxia was also associated with an altered pattern of adenosine-mediated control over Ca2+ efflux. Adenosine (100 microM) elevated Ca2+ efflux twofold in normoxia, but neither adenosine nor the A1-purinoreceptor antagonist 8-phenyltheophylline altered the observed anaerobic suppression. Aerobic administration of 2-10 mM KCN failed to reproduce the anaerobic suppression; however, in conjunction with 10 mM iodoacetate, complete metabolic blockade caused a Ca2+ influx and cell rupture. These observations suggest modulatory control by oxygen over transmembrane Ca2+ efflux involving second-messenger systems in the hypoxic transition.

Design studies for a high-resolution, transportable neutron radiography/radioscopy system (1997)

A preliminary design has been developed for a high-resolution, transportable neutron radiology system (TNRS) concept. The primary system requirement is taken to be a thermal neutron flux of 106 n/(cm2-sec) with a L/D ratio of 100. The approach is to use an accelerator-driven neutron source, with a radiofrequency quadrupole (RFQ) as the primary accelerator component. Initial concepts for all of the major components of the system have been developed, and selected key parts have been examined further. An overview of the system design is presented, together with brief summaries of the concepts for the ion source, low energy beam transport (LEBT), RFQ, high energy beam transport (HEBT), target, moderator, collimator, image collection, power, cooling, vacuum, structure, robotics, control system, data analysis, transport vehicle, and site support. The use of trade studies for optimizing the TNRS concept are also described.
Drilling and Completion Strategies in Naturally Fractured Reservoirs (2000)

Abstract Traditional exploration drilling practices include targeting the structural crest; maintaining a vertical borehole; and drilling over-balanced for safety reasons. All three drilling practices may threaten success in naturally fractured reservoirs in which well and reservoir flow performance relies on flow through natural fractures. Depending on the deformation mechanism of folds, more folding related natural fractures may develop on the limb of the structure than on the crest. At typical depths, open fractures planes are likely to have a subvertical orientation; and a deviated borehole, drilled in a direction normal to the natural fractures, will intersect many more fractures than a vertical one. Over-balanced drilling can result in lost circulation of damaging drilling fluids and solids in the natural fractures. Cementing the fractured zones can further plug natural fractures, leaving little behind pipe to provide sought-after productivity from the natural fractures. This paper offers insight on drilling and completion strategies based on experiences in two South American locations with distinct structural styles. One is a Devonian gas discovery in Bolivia and the other a block southwest of Lake Maracaibo with both mature fields and exploration prospects of Cretaceous age. In both instances, the structural style and orientation provide a framework for borehole trajectory planning.
