RESULTS: (1) The highest occupied molecular orbital (HOMO) consisted mainly of the orbitals in phenyl group and N1 atom; the lowest unoccupied molecular orbital (LUMO) of the molecules was contributed from phenyl group and C11 atom. While the HOMO energies did not show any recognizable relationship with activity, the LUMO energies showed a decreased tendency with increasing activity. The active compounds showed lower LUMO energies. (2) The carbon atom (C11) had the most positive net atom charge. The most active compound had the most positive charge on this carbon, but had the lower charges on the carbonyl oxygen (O12) which was the most negative charge atom. (3) The bond order of carbon-oxygen bond (C11-O10) was invariant across the series of the compounds. (4) Compounds with too high or too low total dipole moment had lower activities, while the most active one had a lower molecular polarizability. CONCLUSION: A molecular model was suggested to explain the possible mode of action by which these compounds inhibit acetylcholinesterase.  (+info)

A 3D computer-aided design system applied to diagnosis and treatment planning in orthodontics and orthognathic surgery. (2/779)

The purpose of this article is to describe a newly developed 3D computer-aided design (CAD) system for the diagnostic set-up of casts in orthodontic diagnosis and treatment planning, and its preliminary clinical applications. The system comprises a measuring unit which obtains 3D information from the dental model using laser scanning, and a personal computer to generate the 3D graphics. When measuring the 3D shape of the model, to minimize blind sectors, the model is scanned from two different directions with the slit-ray laser beam by rotating the mounting angle of the model on the measuring device. For computed simulation of tooth movement, the representative planes, defined by the anatomical reference points, are formed for each individual tooth and are arranged along a guideline descriptive of the individual arch form. Subsequently, the 3D shape is imparted to each of the teeth arranged on the representative plane to form an arrangement of the 3D profile. When necessary, orthognathic surgery can be simulated by moving the mandibular dental arch three-dimensionally to establish the optimum occlusal relationship. Compared with hand-made set-up models, the computed diagnostic cast has advantages such as high-speed processing and quantitative evaluation on the amount of 3D movement of the individual tooth relative to the craniofacial plane. Trial clinical applications demonstrated that the use of this system facilitated the otherwise complicated and time-consuming mock surgery for treatment planning in orthognathic surgery.  (+info)

Following a brief overview of the enzyme structure and function, the article focuses on a number of peptide and non-peptide based HIV-protease inhibitors that are in current clinical use. These drugs are discussed both with respect to their efficacy in treatment of AIDS, and to problems related to insurgence of viral resistance and side effects seen to date in patient populations.  (+info)

Effect of polishing on cyclic fatigue strength of CAD/CAM ceramics. (4/779)

The biaxial flexural strength and cyclic fatigue biaxial flexural strength of CAD/CAM ceramics polished with #220, 400, 600 and 1000 diamond pads were measured in an effort to determine the effect of surface roughness on fatigue behavior of dental ceramics. The surface roughness was improved after polishing with a smaller diamond grain pad. The flexural strengths of the specimens polished with #220, 400, 600 and 1000 diamond pad were 75.2, 76.6, 82.2, and 83.3 MPa, respectively; the fatigue flexural strength of those with #220, 400, 600 and 1000 were 53.0, 58.1, 60.0, and 61.5 MPa, respectively. Both the flexural and fatigue flexural strengths increased with improvement of surface profile. These results suggest the importance of polishing of dental ceramics for not only the static strength but also the cyclic fatigue strength.  (+info)

Influence of filler content and gap dimension on wear resistance of resin composite luting cements around a CAD/CAM ceramic inlay restoration. (5/779)

We investigated the influence of filler content and gap dimension on the wear resistance of composite luting cement around CAD/CAM ceramic inlay restorations. Experimental hybrid dual-cured composite luting cements containing 60, 70, 72, 74 and 80 wt% of silanated barium-silica fillers were used for cementing CAD/CAM ceramic inlay into the cavity. The specimens involving inlay-cement-tooth interfaces were subjected to a three-body wear test. The relation between the interfacial gap dimension and wear loss was also investigated using 60, 70 and 80 wt% filled cements. The cements containing more than 70 wt% filler presented significantly higher wear resistance than 60 wt% filled cement. There was a positive linear relationship between gap dimension and wear loss, and the inclination of the regression line decreased with increasing filler content. These results indicated that the higher filler content of the cement increased the wear resistance and this desirable influence appeared more remarkably in the wider horizontal gap dimension.  (+info)

The Procera abutment--the fifth generation abutment for dental implants. (6/779)

The Branemark dental implant has undergone progressive development in terms of both the implant body itself and the components connecting the implant to the prosthesis. Many screw and abutment designs have been developed, with various degrees of success. About 15 years ago, CAD (computer-assisted design)-CAM (computer-assisted manufacture) technology was introduced to dentists. More recently CAD-CAM has been used in the manufacture of abutments for implants. This article reviews currently available techniques for creating the Procera custom abutment (Nobel Biocare, Goteborg, Sweden) and outlines appropriate applications for this type of implant.  (+info)

Application of secondary structure prediction in antisense drug design targeting protein kinase C-alpha mRNA and QSAR analysis. (8/779)

AIM: To optimize the design of antisense drug targeting protein kinase C-alpha (PKC-alpha) mRNA and obtain better antisense drugs than ISIS3521 that is undergoing clinical trials. METHODS: RNAstructure (version 3.21, 1999) was utilized to predict the optimal and suboptimal secondary structures of human PKC alpha mRNA (GenBank, X52479), and 29 antisense phosphorothioate oligodeoxynucleotides (S-ODN) targeting the secondary structural elements, 3 partly matched S-ODN and 1 scrambled 3521 were designed. ISIS3521 was set as positive control. Mean (n = 3-5) 50% inhibitory effects on proliferation of A549 cells (IC50) of S-ODN were evaluated. Free energies (delta G degree 37) relating to the target secondary structural elements were calculated according to the nearest neighbor model. The quantitative structure-activity relationship (QSAR) analysis through multiple regression was obtained by SPSS. RESULTS: Three S-ODN; (5'-AGCCCA-GCCGCTTGGCTGGG-3', 5'-AGGAGTGCAGCTGC-GTCAAG-3', 5'-TCAGAGGG-ACTGATGACTTT-3') had lower IC50[(48 +/- 7), (50 +/- 4), (64 +/- 2.7) nmol.L-1, respectively] than that of ISIS3521 [(81 +/- 25) nmol.L-1]. The number of bases comprising the target secondary structural element bulge loop, internal loop, and knot, the free energy of S-ODN (delta G degree 37S), and reaction (delta G degree 37R) were important parameters in QSAR equation. In the multiple regression, R was 0.68, P = 0.0193. Not tally with the equation, two S-ODN (5'-TCAAATGGAGG-CTGCCCGGC-3', 5'-AAAACGTCAGCCATGGTCCC-3') with favorable target structures and delta G degree 37 did not behave good activities. CONCLUSION: Computer aided design was helpful to obtain S-ODN with better in vitro effect than current positive drug. The degree of instability of secondary structural elements and delta G degree 37 were important factors for drug activity. Other important factors needed for further investigation.  (+info)

In todays global and digital world, computer-aided design (CAD) can facilitate communication among design team members and make engineers more efficient. To meet the needs of the modern design team it is important that CAD models be formulated in a manner that is easily understood and that they can easily be altered. This work examines the role of an incentive to produce models quickly on feature selection, order, and organization (design intent). The role of design intent on model perception and the time required to alter a model is also investigated. The incentive to produce designs quickly is shown to have a negative effect on model attributes associated with proper design intent. Feature selection and organization are shown to affect model perception. The overall rating of a model is shown to be correlated with the time required to alter it. The importance of design intent on the perception of, and alteration time for, CAD models is shown.. Copyright © 2009 by ASME ...
Detection of chemical signals is critical for cells in nature as well as in synthetic biology, where they serve as inputs for designer circuits. Important progress has been made in the design of signal processing circuits triggering complex biological behaviors, but the range of small molecules recognized by sensors as inputs is limited. The ability to detect new molecules will increase the number of synthetic biology applications, but direct engineering of tailor-made sensors takes time.. Here we describe a way to immediately expand the range of biologically detectable molecules by systematically designing metabolic pathways that transform nondetectable molecules into molecules for which sensors already exist. We leveraged computer-aided design to predict such sensing-enabling metabolic pathways, and we built several new whole-cell biosensors for molecules such as cocaine, parathion, hippuric acid, and nitroglycerin..

Computer-aided design (CAD) of sporting equipment requires knowledge of the mechanical properties of proposed materials. The mechanical properties of composite materials are often not as simple to obtain as those of conventional materials, in which case micro-mechanical modelling could be used in conjunction with CAD software. A micro-mechanical model was used to predict the flexural modulus of composite materials, based on the assumption of partial interfacial adhesion between composite components. It was found that the partial adhesion model was both practical and consistently accurate. The partial adhesion model accounted for adhesion between components by considering an effective shear value at the interface. The model was compared to experimental data for glass, wood and carbon-fibre reinforced polyethylene. It was shown that the adhesion coefficient ranged between 0.1 for carbon fibre, 0.5 for glass fibre and 0.8 for the wood fibre composites. It was shown that using micro-mechanical ...

This thesis presents a new computer-aided linkage design and simulation system for task driven path generation problem. Mechanism design is considered a mixture of science and art. The former is about utilizing computers to rigorously sizing a mechanism in meeting a set of design requirements. And the latter is about taking advantage of designers experience to narrow down design domain and speed up the design process. The ultimate goal of the presented design system is to incorporate both science and art into the linkage design process by (1) developing an automatic design framework based on library searching and optimization techniques and (2) developing an interactive design framework based on advanced human-computer interfaces. To enable the design automation framework, we first built a library of open and closed planar curves generated by commonly used planar linkages. We then turned the classical linkage path generation problem into a library searching problem together with a local ...

The role of structural activities and other solution searching activities in design learning and problem solving have been identified in laboratory studies of problem solving and also in case studies of design teaching.. In laboratory studies, students have solved creative problems collaboratively under various communication conditions. The case studies follow students working on the same problem under two conditions one group is taught using traditional face-to-face teaching while the other group is additionally supported by a textbased web board. This paper review findings from three experiments from which we can see that students producing above average solutions involved more structural activities than the mediocre cases. These successful cases engaged in textual expression of their design solutions. Computer tools for design should therefore support multiple representations of design work ...

Mandibular sagittal split osteotomy (SSO) is an operation performed for the correction of mandibular deformities. In this operation, sharp rotary tools are used during osteotomies and this can induce some complications. For example, if the inferior alveolar nerve is damaged, paralysis of the teeth, the lateral side of the tongue, and the corner of the lip can occur. To decrease the occurrence of such possible complications, we designed and manufactured a novel computer-assisted, patient-specific SSO guide and soft tissue retractor in our previous study. And, we first tested this apparatus on a cadaveric bone in vitro. Now, in this study, a surgical application of the instrument, which was designed and manufactured according to the requirements of the mandibular sagittal split osteotomies, was performed. This paper gives and discusses the results obtained from in vivo application of the apparatus.. ...
Genetically-encoded biosensors offer a wide range of opportunities to develop advanced synthetic biology applications. Circuits with the ability of detecting and quantifying intracellular amounts of a compound of interest are central to whole-cell biosensors design for medical and environmental applications, and they also constitute essential parts for the selection and regulation of high-producer strains in metabolic engineering. However, the number of compounds that can be detected through natural mechanisms, like inducible transcription factors, is limited; expanding the set of detectable compounds is therefore highly desirable.. Here, we present the SensiPath webserver, accessible at http://sensipath.micalis.fr.. SensiPath implements a strategy to enlarge the set of detectable compounds by screening for multi-step enzymatic transformations converting non-detectable compounds into detectable ones. The SensiPath approach is based on the encoding of reactions through signature descriptors to ...

0047] The invention is directed to a method for designing a modeled object within a session of a computed-aided design system interacting with a database, e.g. a PLM database. A session keeps track of operations performed by the user on the system and provides for the user a working environment with a specific user context. The method according to the invention comprises detecting a designing operation performed by the user, the designing operation being applied to an initial modeled object within the session. Then, a signature is computed from a set of properties of the initial modeled object and/or a set of properties of the session. Next, modeled objects having the closest signatures to the signature of the initial modeled object within the session are retrieved in the database; the closeness of the signature of a modeled object with the signature of the initial modeled object may be determined with the distance between the two signatures. Thus, the modeled objects, whose respective ...

CAD/CAM is a field of dentistry and prosthodontics using CAD/CAM (computer-aided design and computer-aided manufacturing) to improve the design and creation of dental restorations, especially dental prostheses, including crowns, crown, veneers, inlays and onlays, fixed bridges, dental implant restorations, dentures (removable or fixed), and orthodontic appliances. There exists a misconception that the CAD/CAM process is complicated and time-consuming. However, the CAD/CAM system is simple to operate, versatile, and precise. All-ceramic restorations can be designed and milled chair side, with the added advantage of elimination of traditional impressions and temporaries, and the patient leaves the appointment in about an hour with the final restoration in place. Dental CAD/CAM is approaching 20 years of clinical experience and has a proven track record on all relevant aspects of clinical performance, including fit, longevity and survival rates, sensitivity, strength, and wear.

The rapid prototyping technology used in medicine is defined as either subtractive or additive depending on the printing method used.1 The only subtractive technique used in medical applications is milling, in which the shape of the model is milled from a block of material (either polyurethane or other foam product). Although low in cost, milling is limited in producing models that define surface anatomy alone with overall poor geometric accuracy.. The most common additive technologies used in medicine are selective laser sintering, fused deposition modeling, multijet modeling/3D printing, and stereolithography. Selective laser sintering (3-D Systems Inc, Rock Hill, SC) uses a high-power laser (eg, carbon dioxide laser) to fuse small particles of plastic, metal, or ceramic powders into a 3D object. The laser selectively fuses a pattern into the surface of a thermoplastic powder bed by scanning cross sections generated from the computer-aided design file of the computerized 3D surface model. ...

A tooth that has been structurally damaged by decay or trauma sometimes needs to be crowned or "capped" so that it can look good and function properly again. A crown is a durable covering that is custom-made to fit over the entire tooth from the gum line up. Crown fabrication traditionally takes place in a dental laboratory. But these days, theres a much more convenient alternative: same-day crowns made right here in the dental office.. Advanced dental technology known as Computer-Aided Design/Computer-Aided Manufacturing, or CAD/CAM, allows us to fabricate laboratory-grade crowns and other dental restorations in minutes. Its an amazing innovation when you consider that traditionally, crowns take two or three visits and just as many weeks of waiting. Now you can have a restored tooth without the wait.. Best of all, studies have shown that CAD/CAM tooth restorations are just as successful as crowns made with traditional materials and techniques. And the amazingly lifelike appearance of a ...
These need two or more visits and include inlays, onlays, porcelain and resin veneers, crowns, and bridges. These are constructed with gold, base metal alloys, ceramics, porcelain fused to metal or specially formulated composites. At the first visit, a dentist will prepare the tooth and make an impression of the area that will be restored. At the second visit, the dentist will cement the new restoration into the prepared area. Some offices use newer technologies called CAD/CAM (computer-aided design/computer-aided manufacturing) that allows them to produce the indirect restoration in the office and deliver it at the same appointment. This saves the patient a return visit.. For an indirect restoration, a dentist may use an all-porcelain, or ceramic, material. This material looks like natural tooth enamel in color and translucency. Another type of indirect restoration may use porcelain that is fused to metal, which provides additional strength. Gold alloys are used often for crowns, foundations ...

Complex glenoid bone deformities present the treating surgeon with a complex reconstructive challenge. Although glenoid bone loss can be encountered in the primary setting (degenerative, congenital, post-traumatic), severe glenoid bone loss is encountered in most revision total shoulder arthroplasties. Severe glenoid bone loss is treated with various techniques including hemiarthroplasty, eccentric reaming, and glenoid reconstruction with bone autografts and allografts. Despite encouraging short- to mid-term results reported with these reconstruction techniques, the clinical and radiographic outcomes remain inconsistent and the high number of complications is a concern. To overcome this problem, more recently augmented components and patient specific implants were introduced. Using the computer-aided design and computer-aided manufacturing technology patient-specific implants have been created to reconstruct the glenoid vault in cases of severe glenoid bone loss.In this article we describe a patient
Micro- and nano-structuring have been highlighted over several decades in both science and engineering fields. In addition to continuous efforts in fabrication techniques, investigations in scalable nanomanufacturing have been pursued to achieve reduced feature size, fewer constraints in terms of materials and dimensional complexity, as well as improved process throughput. In this study, based on recent micro-/nanoscale fabrication processes, characteristics and key requirements for computer-aided design and manufacturing (CAD/CAM) systems for scalable nanomanufacturing were investigated. Requirements include a process knowledge database, standardized processing, active communication, adaptive interpolation, a consistent coordinate system, and management of peripheral devices. For scalable nanomanufacturing, it is important to consider the flexibility and expandability of each process, because hybrid and bridging processes represent effective ways to expand process capabilities.

Classical algebraic geometry has been virtually ignored in computer-aided geometric design. However, because it deals strictly with algorithms, it is really more suited to this field than is modern algebraic geometry, which introduces abstractions far removed from the algorithmic nature of computer-aided design. This tutorial examines resultants, curve implicitization, curve inversion, and curve intersection. Discussion follows a series of examples simple enough for those with only a modest algebra background to follow.

DOI: 10.11607/jomi.3025 Purpose: Recent clinical studies have shown that implant placement is highly predictable with computergenerated surgical guides; however, the reliability of these guides has not been compared to that of conventional guides clinically. This study aimed to compare the accuracy of reproducing planned implant positions with computer-generated and conventional surgical guides using a split-mouth design. Materials and Methods: Ten patients received two implants each in symmetric locations. All implants were planned virtually using a software program and information from cone beam computed tomographic scans taken with scan appliances in place. Patients were randomly selected for computer-aided design/computer-assisted manufacture (CAD/CAM) guided implant placement on their right or left side. Conventional guides were used on the contralateral side. Patients underwent operative cone beam computed tomography postoperatively. Planned and actual implant positions were compared using ...

The development of freeze-form extrusion fabrication (FEF) process to fabricate three-dimensional (3D) ceramic parts with use of sacrificial material to build support sections during the fabrication process is presented in this paper. FEF is an environmentally friendly, additive manufacturing (AM) process that builds 3D parts in a freezing environment layer-by-layer by computer controlled extrusion and deposition of aqueous colloidal pastes based on computer-aided design (CAD) models. Methyl cellulose was identified as the support material, and alumina was used as the main material in this study. After characterizing the dynamics of extruding alumina and methyl cellulose pastes, a general tracking controller (GTC) was developed and applied to control the extrusion force in depositing both alumina and methyl cellulose pastes. The controller was able to reduce the time constant of the closed-loop system by more than 65% in comparison to the open-loop control system. Freeze-drying was used to ...
0055] Like the bone model from step 104, the prosthesis model from step 106 of method 100 (FIG. 1) may be a digital model that is designed using a suitable computer planning system having, for example, computer-aided design (CAD) software. The computer planning system may allow the designer to define or specify certain boundaries of the prosthesis model. For example, the computer planning system may allow the designer to define or specify the shape of an exposed surface or an articulating surface of the prosthesis model. The computer planning system may automatically define other boundaries of the prosthesis model. For example, the computer planning system may automatically define the shape of a bone-contacting surface of the prosthesis model as substantially a negative of the bone model so that the prosthesis model conforms to the bone model and is perfectly contoured to fit against the bone model. In this manner, once manufactured, a patient-specific, bone-contacting surface of the orthopaedic ...

Since the late 1950s, computers have been used to assist with the design and study of combat vehicle systems. The result has been a reduction in the amount of time and money required to take a system from the drawing board to full-scale production as well as increased efficiency in testing and evaluation. In 1979, the U.S. Army Ballistic Research Laboratory (BRL) (now the U.S. Army Research Laboratory [ARL]) expressed a need for interactive tools that could assist with the computer simulation and engineering analysis of combat vehicle systems and environments. When no existing computer-aided design (CAD) package was found to be adequate for this purpose, BRL software developers began assembling a suite of utilities capable of interactively displaying, editing, and interrogating geometric models. This suite became known as BRL-CAD. Now comprising almost a million lines of C code, BRL-CAD has become a powerful constructive solid geometry (CSG) modeling package that has been licensed at over 2,000 ...

A system for assessing energy usage reads read at least one computer-aided design (CAD) file relating to the architecture of a facility and extracts information from the CAD file for use in determining static energy characteristics corresponding to the architecture of the facility, acquires information for use in determining dynamic energy characteristics of the facility, and calculates a predicted energy usage of the facility based at least in part on the static and dynamic energy characteristics. The system further acquires data from at least one sensor configured to measure actual energy usage of the facility in real-time and calculates the actual energy usage of the facility. When the actual energy usage exceeds the predicted energy usage, the system transmits an alert to a user and determines corrective measures to reduce energy usage.
Most multimedia content today consists primarily of text, 2D images, video, and audio. Multimedia of the near future will additionally rely heavily on 3D graphics. The creation and use of 3D graphics in turn draws upon the two closely related disciplines of geometric design (the creation of the geometric objects), and computer graphics (the animation and display of the objects). These disciplines have been extraordinarily vibrant and diverse, with current applications including flight simulation, medical imaging, scientific visualization, computer-aided design, and entertainment. Results obtained in research laboratories over the past twenty years have given rise to a multi-billion dollar industry. The pending 3D graphics revolution is due in large part to impressive improvements in processor speeds and memory capacities. More impressive still are numerous algorithmic improvements that have opened up new application areas and have provided remarkable asymptotic reductions in both running time ...

Problems exist in image sequence processing that require an ordered set of object views. In some cases, multiple angled images are acquired in random order and the angle of view information is not available. When this occurs, the poses have to be put into proper order. For example, in databases containing images of an object or scene taken over a period of time, each image pose or angled-view with respect to the camera or scene is unknown. This is important to achieve a complete or partial three-dimensional reconstruction. Other applications exist in photogrammetry, machine vision, computer-aided design, and military intelligence. The main contribution of this thesis is an automated method for ordering images of random object views. This method uses Principal Component Analysis (PCA) and a confidence metric in eigenspace. The confidence measure is based on local curvature and correlation of the estimated pose trajectory in a multidimensional manifold. The use of the confidence metric is for detecting
Prefabrication - a decades-old concept for saving money and time in construction once dismissed as synonymous with low quality - is making a huge comeback in an era when advances in computer-aided design have reinvented the idea into an indispensable tool for some of the biggest commercial building projects.. The "prefab" concept blossomed in the 1950s, when it became shorthand for slapped-together housing erected as quickly as possible to meet the needs of the baby boom generation. For the first time, builders used components that were assembled in off-site workshops and shipped in on trucks in order to mass-produce millions of starter homes across the country. The results were often less-than-stellar, derided in popular culture as cookie-cutter and soulless - think Pete Seegers song "Little Boxes." Skip ahead to 2014, when multimillion-dollar apartment buildings, hospitals, massive data centers and commercial buildings of all types from major builders such as Opus Design Build and Mortenson ...

Thanks to Sandy for telling me about this.. COLUMBUS, Ohio - Seeking to improve on nature, scientists used a spice-based compound as a starting point and developed synthetic molecules that, in lab settings, are able to kill cancer cells and stop the cells from spreading.. The researchers are combining organic chemistry, computer-aided design and molecular biology techniques in developing and testing pharmaceutical compounds that can fight breast and prostate cancer cells. The synthetic molecules are derived from curcumin, a naturally occurring compound found in the spice turmeric.. Centuries of anecdotal evidence and recent scientific research suggest curcumin has multiple disease-fighting features, including anti-tumor properties. However, when eaten, curcumin is not absorbed well by the body. Instead, most ingested curcumin in food or supplement form remains in the gastrointestinal system and is eliminated before it is able to enter the bloodstream or tissues.. "Newer evidence describes how ...

Rapid Prototyping - The Heart of The Matter People come in all sizes and so do their heart arteries. Many doctors wish they could have custom fitted stents for their heart surgery patients. Currently, heart surgeons only have small, medium, and large heart stents to place in an artery. With rapid prototyping and manufacturing of custom stent sizes, patients can have better fitting stents and better outcomes from their angioplasty procedures.. Stent Market. A report by Research and Markets states that the global market for heart stents is expected to grow steadily until 2021. Authors of the report cite multiple reasons for the increase including an aging population, increasing metabolic diseases, and preferences for minimally invasive surgeries. Improvement in stent design and customized stents is also fueling growth.. Heart Stents. A heart stent, also known as a cardiac stent or coronary stent, is a tube placed in an artery, a blood vessel leading away from the heart. In this procedure called ...
Objectives: The primary objective was to assess the impact of two denture fabrication techniques, conventional and CAD/CAM, on oral health-related quality of life (OHRQoL) and patient satisfaction in complete denture wearers. The secondary objective was to compare the level of microorganisms present on complete dentures from the two fabrication techniques. Methods: Twenty-eight completely edentulous subjects (16 men and 21 women, age range from 49 to 87 years old.), who had been edentulous for at least 6 months, were wearing ill-fitting complete dentures, or unsatisfied with their existing complete dentures were recruited. Subjects were randomized to conventional and computer-aided design/ computer-aided manufacturing (CAD/CAM) treatment groups. Subjects in both groups were given the OHIP-EDENT (Oral Health Impact Profile for Edentulous Patients) and patient satisfaction questionnaires to record the data at baseline and at 1 month post-delivery of the new prostheses. Plaque samples were collected from

Large-pitch kagome-lattice hollow-core photonic crystal fibers (HC-PCFs) offer appealing optical properties for beam delivery and remote sensing. However, focusing their optical mode on a submicrometer spot can be challenging due to the large mode diameter and low numerical aperture of these fibers. Here, we demonstrate that a 30 μm latex microsphere directly set at the HC-PCF end-face provides an efficient means to focus the fiber mode down to a spot of 540 nm full width at half-maximum thanks to a photonic nanojet effect. The system is used for fluorescence imaging and direct laser writing on a thin absorbing layer. Potential applications include inspection of semiconductor wafers, photolithography, laser surgery, fluorescence sensing, or optical transfection.. © 2012 Optical Society of America.

The advent of 3D printing technologies promises to make microfluidic organ-on-chip technologies more accessible for the biological research community. To date, hydrogel-encapsulated cells have been successfully incorporated into 3D printed microfluidic devices. However, there is currently no 3D printed microfluidic device that can support multicellular spheroid culture, which facilitates extensive cell-cell contacts important for recapitulating many multicellular functional biological structures. Here, we report a first instance of fabricating a 3D printed microfluidic cell culture device capable of directly immobilizing and maintaining the viability and functionality of 3D multicellular spheroids. We evaluated the feasibility of two common 3D printing technologies i.e. stereolithography (SLA) and PolyJet printing, and found that SLA could prototype a device comprising of cell immobilizing micro-structures that were housed within a microfluidic network with higher fidelity. We have also ...
Collaboration with P. Viale, P. Leproux et V. Couderc XLIM - Photonics group, Limoges, France.. We have built a compact broad-band femtosecond spectrometer based on a probe light supercontinuum generated in a birefringent photonic crystal fiber (see the "experimental techniques" of GONLO). These micro-structured material systems can be tailored for very efficient generation of broadband "white-light" continua using only moderate laser pulse energies derived e.g. from a Titane-Saphire oscillator, rather than from an expensive multi-component amplified laser chain. Previous spectrometers of that kind where however limited to wavelengths , 550 nm or used 800 nm for excitation. The use of multi-channel detection with a CCD operated at 600 Hz read-out rate provides more precise spectral information, and a high signal-to-noise ratio. The ultrafast photo-isomerisation of Malachite Green (MG) is studied in a proof-of-principle experiment.. The system is based on a Ti:Sapphire oscillator with an extended ...
An improved image similarity method is introduced to recognize breast cancer, and it is incorporated into a computer-aided breast cancer detection system through Bayes Theorem. Radiologists can use the differences between the left and right breasts, or asymmetry, in mammograms to help detect certain malignant breast cancers. Image similarity is used to determine asymmetry using a contextual and then a spatial comparison. The mammograms are filtered to find the most contextually significant points, and then the resulting point set is analyzed for spatial similarity. We develop the analysis through a combination of modeling and supervised learning of model parameters. This process correctly classifies mammograms 84% of the time, and significantly improves the accuracy of a computer-aided breast cancer detection system by 71%.. ...
