    The da Vinci surgical system was developed by Intuitive Surgical Inc. in the United States as an endoscopic surgical device to assist remote control surgeries. In 1998, the Da Vinci system was first used for cardiothoracic procedures. Currently a combination of robot-assisted internal thoracic artery harvest together with coronary artery bypass grafting (CABG) through a mini-incision (ThoraCAB) or totally endoscopic procedures including anastomoses under robotic assistance (TECAB) are being conducted for the treatment of coronary artery diseases. With the recent advances in catheter interventions, hybrid procedures combining catheter intervention with ThoraCAB or TECAB are anticipated in the future.On the other hand, with the decrease in number of coronary artery bypass surgeries, the share of valvular surgeries is expected to increase in the future. Among them, mitral valvuloplasty for mitral regurgitation is anticipated to be conducted mainly by low-invasive procedures, represented by minimally invasive cardiac surgery( MICS) and robot-assisted surgery. Apart from the intrinsic good surgical view, robotic-assisted systems offer additional advantages of the availability of an amplified view and the easy to observe the mitral valve in the physiological position. Thus, robotic surgical surgeries that make complicated procedures easier are expected to accomplish further developments in the future. Furthermore, while the number of surgeries for atrial septal defects has decreased dramatically following the widespread use of Amplatzer septal occluder, robotic surgery may become a good indication for cases in which the Amplatzer device is not indicated. In Japan, clinical trial of the da Vinci robotic system for heart surgeries has been completed. Statutory approval of the da Vinci system for mitral regurgitation and atrial septal defects is anticipated in the next few years. PMID:25138939

    Robot-assisted surgery using the da Vinci surgical system has attracted attention because of excellent operability without shaking by joint forceps under the clear vision of a three-dimensional high-definition camera in lung cancer surgery. Although this form of advanced medical care is not yet approved for insurance coverage, it is at the stage of clinical research and expected to be useful in hilar exposure, lymph node dissection, and suturing of the lung parenchyma or bronchus. Lung cancer surgery with the da Vinci system has the advantage of combining thoracotomy and minimally invasive surgery in video-assisted thoracic surgery. However, safety management, education, and significant cost are problems to be resolved. Several important issues such as sharing knowledge and technology of robotic surgery, education, training, development of new instruments, and acquisition of advanced medical insurance are discussed for the future development of robotic surgical systems.

    Robotic operational systems improve accuracy, control of and skilful management of surgical procedures up to levels unachievable by a human factor itself. A surgeon is also allowed to conduct the types of miniinvasive procedures, which cannot be conducted using contemporary technologies. High degree of the procedure's safety can be achieved. Currently, the robotic surgical systems are used in top clinics worldwide and the concept of the robotic operating theatre is considered to become standard for some procedures in future. In October 2005, a multispecialist robotic centre was opened in the Hospital Na Homolce, which then created a new qualitative standard in the miniinvasive surgical management. The authors present the initial group of patients, who were operated from November 2005 to January 2006 with employement of the da Vinci robotic system, listing its pros and cons. PMID:16805339

    Robot-assisted minimally invasive surgery has become common in recent years. We used the da Vinci surgical system and managed anesthesia in 6 cases of bilateral internal mammary artery dissection and construction of a composite graft using the radial artery. To ensure vision inside the thoracic cavity, endoscopic robotic surgery employs the inflation of the thoracic cavity with carbon dioxide, producing a pneumothorax and turning the thoracic cavity into a positive pressure chamber. Thus, marked acidosis and circulatory changes manifest during anesthetic management. Although robotic surgery is considered "minimally invasive, such surgery involves a number of problems in terms of anesthetic management, and these problems must be examined. PMID:20169956

    Leonardo Da Vinci's anatomical drawings continue to attract the attention of the medical community. One of the intriguing aspects of these drawings is Da Vinci's use of right-to-left mirrored writing. Many hypotheses have been proposed to explain his mirrored writing. This article presents a new explanation that takes into consideration the drawing material used and Da Vinci's known innovative ability. A collection of his anatomical drawings is currently on display in Boston at the Museum of Fine Arts. PMID:8333692

  12. Depth asymmetry in da Vinci stereopsis.

    PubMed

    Häkkinen, J; Nyman, G

    1996-12-01

    We investigated processes that determine the depth localization of monocular points which have no unambiguous depth. It is known that horizontally adjacent binocular objects are used in depth localization and for a distance of 25-40 min arc monocular points localize to the leading edge of a depth constraint zone, which is an area defined by the visibility lines between which the points in the real world must be. We demonstrate that this rule is not valid in complex depth scenes. Adding other disparate objects to the scene changes the localization of the monocular point in a way that cannot be explained by the da Vinci explanation of monocular-binocular integration. The effect of additional disparate objects is asymmetric in depth: a crossed object does not affect the da Vinci effect but an uncrossed object biases the depth localization of monocular objects to uncrossed direction. We conclude that a horizontally adjacent binocular plane does not completely determine the depth localization of a monocular point and that depth spreading from other binocular elements biases the localization process.

    Purpose: To evaluate the feasibility of using the da Vinci robotic system for radioactive seed placement in the wedge resection margin of pigs' lungs. Methods and materials: Video-assisted thoracoscopic wedge resection was performed in the upper and lower lobes in pigs. Dummy {sup 125}I seeds embedded in absorbable sutures were sewn into the resection margin with the aid of the da Vinci robotic system without complications. In the 'loop technique,' the seeds were placed in a cylindrical pattern; in the 'longitudinal,' they were above and lateral to the resection margin. Orthogonal radiographs were taken in the operating room. For dose calculation, Variseed 66.7 (Build 11312) software was used. Results: With looping seed placement, in the coronal view, the dose at 1 cm from the source was 97.0 Gy; in the lateral view it was 107.3 Gy. For longitudinal seed placement, the numbers were 89.5 Gy and 70.0 Gy, respectively. Conclusion: Robotic technology allows direct placement of radioactive seeds into the resection margin by endoscopic surgery. It overcomes the technical difficulties of manipulating in the narrow chest cavity. With the advent of robotic technology, new options in the treatment of lung cancer, as well as other malignant tumors, will become available.

    The study of the human form is fundamental to both science and art curricula. For vertebrates, perhaps no feature is more important than the skeleton to determine observable form and function. As Leonard da Vinci's famous Proportions of the Human Figure (Virtruvian Man) illustrates, the size, shape, and proportions of the human body are defined by bones and their articulations. In this unit that focuses on the human skeleton, students are introduced to these concepts by asking them both to study da Vinci's drawing and build their own model of the human skeleton. Units on animal camouflage and architecture are also presented to further support the art and science connection.

    A system for real-time ultrasound (US) elastography will advance interventions for the diagnosis and treatment of cancer by advancing methods such as thermal monitoring of tissue ablation. A multi-stream graphics processing unit (GPU) based accelerated normalized cross-correlation (NCC) elastography, with a maximum frame rate of 78 frames per second, is presented in this paper. A study of NCC window size is undertaken to determine the effect on frame rate and the quality of output elastography images. This paper also presents a novel system for Online Tracked Ultrasound Elastography (O-TRuE), which extends prior work on an offline method. By tracking the US probe with an electromagnetic (EM) tracker, the system selects in-plane radio frequency (RF) data frames for generating high quality elastograms. A novel method for evaluating the quality of an elastography output stream is presented, suggesting that O-TRuE generates more stable elastograms than generated by untracked, free-hand palpation. Since EM tracking cannot be used in all systems, an integration of real-time elastography and the da Vinci Surgical System is presented and evaluated for elastography stream quality based on our metric. The da Vinci surgical robot is outfitted with a laparoscopic US probe, and palpation motions are autonomously generated by customized software. It is found that a stable output stream can be achieved, which is affected by both the frequency and amplitude of palpation. The GPU framework is validated using data from in-vivo pig liver ablation; the generated elastography images identify the ablated region, outlined more clearly than in the corresponding B-mode US images.

    Robot-assisted laparoscopic radical prostatectomy (RALRP) using the da Vinci surgical system is the current state-of-the-art treatment option for clinically confined prostate cancer. Given the limited field of view of the surgical site in RALRP, several groups have proposed the integration of transrectal ultrasound (TRUS) imaging in the surgical workflow to assist with accurate resection of the prostate and the sparing of the neurovascular bundles (NVBs). We previously introduced a robotic TRUS manipulator and a method for automatically tracking da Vinci surgical instruments with the TRUS imaging plane, in order to facilitate the integration of intraoperative TRUS in RALRP. Rapid and automatic registration of the kinematic frames of the da Vinci surgical system and the robotic TRUS probe manipulator is a critical component of the instrument tracking system. In this paper, we propose a fully automatic registration technique based on automatic 3-D TRUS localization of robot instrument tips pressed against the air-tissue boundary anterior to the prostate. The detection approach uses a multiscale filtering technique to identify and localize surgical instrument tips in the TRUS volume, and could also be used to detect other surface fiducials in 3-D ultrasound. Experiments have been performed using a tissue phantom and two ex vivo tissue samples to show the feasibility of the proposed methods. Also, an initial in vivo evaluation of the system has been carried out on a live anaesthetized dog with a da Vinci Si surgical system and a target registration error (defined as the root mean square distance of corresponding points after registration) of 2.68 mm has been achieved. Results show this method's accuracy and consistency for automatic registration of TRUS images to the da Vinci surgical system. PMID:23674418

    The novel The Da Vinci Code, by Dan Brown has been on best-seller lists for over two years. An examination of Brown's previous novels reveals a well-designed plot line shared by all four novels that not only makes them good "thrillers" but also creates a mythological structure to the novels that draws on common unconscious fantasies in the same way that fairy tales do. One aspect of this mythological structure is the use of evil conspiracies (and benign ones as well) for the protagonist to overcome. In addition, The Da Vinci Code presents a religious theme involving legends about Mary Magdalene. This theme touches on the role of a feminine aspect to divinity in allowing for an erotic connection with the divine. PMID:16448349

    2013-01-01

    For several of Leonardo da Vinci's paintings, such as The Virgin and Child with St Anne or the Mona Lisa, there exist copies produced by his own studio. In case of the Mona Lisa, a quite exceptional, rediscovered studio copy was presented to the public in 2012 by the Prado Museum in Madrid. Not only does it mirror its famous counterpart superficially; it also features the very same corrections to the lower layers, which indicates that da Vinci and the 'copyist' must have elaborated their panels simultaneously. On the basis of subjective (thirty-two participants estimated painter-model constellations) as well as objective data (analysis of trajectories between landmarks of both paintings), we revealed that both versions differ slightly in perspective. We reconstructed the original studio setting and found evidence that the disparity between both paintings mimics human binocular disparity. This points to the possibility that the two Giocondas together might represent the first stereoscopic image in world history. PMID:24303752

    Intraoperative tracking of laparoscopic instruments is a prerequisite to realize further assistance functions. Since endoscopic images are always available, this sensor input can be used to localize the instruments without special devices or robot kinematics. In this paper, we present an image-based markerless 3D tracking of different da Vinci instruments in near real-time without an explicit model. The method is based on different visual cues to segment the instrument tip, calculates a tip point and uses a multiple object particle filter for tracking. The accuracy and robustness is evaluated with in vivo data.

    We have previously reported on the importance of appropriate robot-arm settings and replacement of instrument ports in robot-assisted thoracic surgery, because the thoracic cavity requires a large space to access all lesions in various areas of the thoracic cavity from the apex to the diaphragm and mediastinum and the chest wall. (1 - 3) Moreover, it can be difficult to manipulate the da Vinci Surgical System using only arms No. 1 and No. 2 depending on the tumor location. However, arm No. 3 is usually positioned on the same side as arm No. 2, and sometimes it is only used as an assisting-arm to avoid conflict with other arms ( Fig. 1 ). In this report, we show how robot-arm No. 3 can be used with maximum effectiveness in da Vinci-assisted thoracic surgery. [Figure: see text]. PMID:26011219

    Objective: To define the learning curve for daVinci-assisted laparoscopic radical prostatectomy (DLP) at our institution. Methods: The data from 170 patients who underwent DLP between August 2002 and December 2004 by a single surgeon (MTG) were reviewed. Operative time, hemoglobin decrease, conversion to open procedure, positive margin rates, complications, length of stay (LOS), length of catheterization, continence, and erectile function were analyzed. Results: Hemoglobin decrease (p=0.11), positive margin rates (p=0.80), and early urinary continence (p=0.17) did not significantly correlate with surgical experience. A trend towards lower complications (p=0.07) and an earlier return of erectile function (p=0.09) was noted with increased experience with DLP. Operative time, hospital stay, catheterization time, and open conversion showed significant association with patient sequence. Median operative time for the first 60 and the last 110 patients was 323.5 and 239.5 minutes (p=<0.0001), respectively. Median LOS for the aforementioned groups was 53 and 51 hours (p=0.009). Length of catheterization declined significantly between the first 60 and the remaining 110 patients, 14 as compared to 11.5 days (p=<0.0001). Eight open conversions occurred, six were in the first 30 patients (p=0.03). Conclusion: As an indicator of the learning curve, the operative time in our series showed no correlation with sequence after the 60 th patient. Thus, despite the advantages of robotics, the learning curve to efficient performance of daVinciassisted laparoscopic radical prostatectomy is long. Oncological and functional outcomes should not be affected during the learning curve.

    PubMed

    Harsch, H E

    1994-02-01

    In view of the fact that as a child Sigmund Freud was looked after by two mothers--his actual mother and a nursemaid--it is hardly surprising that traces of this pre-oedipal situation, fraught as it was with traumatisation and loss, should be discernible in the works of the creator of psychoanalysis. Freud's continued preoccupation with the Oedipus myth, his interest in "great men" like da Vinci and Michelangelo, and finally his identification with the figure of Moses are pointers not only to the paternal dimension (as long suggested by Freud's biographers) but also to the maternal dimension and its significance for Freud's life and work. The author demonstrates that those mythical and historical figures which Freud identified with--Oedipus, da Vinci, Michelangelo, Moses--themselves all had two mothers and sublimated this traumatic experience into outstanding achievements, the same being true of Freud himself "who solved the famous riddle and was a most powerful man".

    Background and Objectives: Robot-assisted laparoscopic surgery is often taught with the surgical mentor at the surgeon console and the trainee at the patient's bedside. The da Vinci dual console (Intuitive Surgical, Sunnyvale, California) allows a surgical mentor to teach with both the mentor and the trainee working at a surgeon console simultaneously. The purpose of this study is to evaluate the effectiveness of the dual console versus the single console for teaching medical students robotic tasks. Methods: Forty novice medical students were randomized to either the da Vinci single-console or dual-console group and were taught 4 knot-tying techniques by a surgical mentor. The students were timed while performing the tasks. Results: No statistically significant differences in mean task times were observed between the single- and dual-console groups: interrupted stitch with a 2-handed knot (300 seconds for single vs 294 seconds for dual, P = .59), interrupted stitch with a 1-handed knot (198 seconds for single vs 212 seconds for dual, P = .88), figure-of-8 stitch with a 2-handed knot (261 seconds for single vs 219 seconds for dual, P = .20), and figure-of-8 stitch with a 1-handed knot (200 seconds for single vs 199 seconds for dual, P = .53). Conclusion: No significant difference was observed in performance time when teaching knot-tying techniques to medical students using the da Vinci dual console compared with the single console. More research needs to be performed on the utility of the da Vinci dual console in surgical training. PMID:25392618

    Introduction and Objectives. To demonstrate the safety and efficacy of the robot-assisted partial nephrectomy (RAPN) technique in an Australian setting. Methods. Between November 2010 and July 2014, a total of 76 patients underwent 77 RAPN procedures using the Da Vinci Surgical System© at our institution. 58 of these procedures were performed primarily by the senior author (PB) and are described in this case series. Results. Median operative time was 4 hours (range 1.5–6) and median warm ischaemic time (WIT) was 8 minutes (range 0–30) including 11 cases with zero ischaemic time. All surgical margins were clear with the exception of one patient who had egress of intravascular microscopic tumour outside the capsule to the point of the resection margin. Complications were identified in 9 patients (15.8%). Major complications included conversion to open surgery due to significant venous bleeding (n = 1), reperfusion injury (n = 1), gluteal compartment syndrome (n = 1), DVT/PE (n = 1), and readmission for haematuria (n = 1). Conclusion. This series demonstrates the safety and efficacy of the RAPN technique in an Australian setting when performed by experienced laparoscopic surgeons in a dedicated high volume robotic centre.

    It is estimated that around the year 1480 Leonardo da Vinci painted Saint Jerome in the Wilderness, representing the saint during his years of retreat in the Syrian dessert where he lived the life of a hermit. One may interpret Leonardo's Saint Jerome in the Wilderness as St. Jerome practicing self-chastisement with a stone in his right hand, seemingly punching his chest repeatedly. The stone, the lion and a cardinal's hat are conventionally linked to the saint. A skull was also almost always present with the image of the saint symbolically representing penance. With careful analysis of the painting one can identify the skull which is hidden in an arc represented as a lion's tail. The image is of a hemicranium (midline sagittal view) showing the intracranial dura, including the falx and tentorium, and venous system with the sinuses and major deep veins. This may have been the first time when the intracranial sinuses and the major deep venous vessels were illustrated. PMID:23971176

    We present here the organization of the recently-constituted da Vinci European BioBank (daVEB, https://www.davincieuropeanbiobank.org/it). The biobank was created as an infrastructure to support the activities of the Fiorgen Foundation (http://www.fiorgen.net/), a nonprofit organization that promotes research in the field of pharmacogenomics and personalized medicine. The way operating procedures concerning samples and data have been developed at daVEB largely stems from the strong metabolomics connotation of Fiorgen and from the involvement of the scientific collaborators of the foundation in international/European projects aimed to tackle the standardization of pre-analytical procedures and the promotion of data standards in metabolomics.

    The application of AES algorithm in the digital cinema system avoids video data to be illegal theft or malicious tampering, and solves its security problems. At the same time, in order to meet the requirements of the real-time, scene and transparent encryption of high-speed data streams of audio and video in the information security field, through the in-depth analysis of AES algorithm principle, based on the hardware platform of TMS320DM6446, with the software framework structure of DaVinci, this paper proposes the specific realization methods of AES algorithm in digital video system and its optimization solutions. The test results show digital movies encrypted by AES128 can not play normally, which ensures the security of digital movies. Through the comparison of the performance of AES128 algorithm before optimization and after, the correctness and validity of improved algorithm is verified.

    Following the discovery of discoloration on some pages of the Atlantic Codex (AC) of Leonardo da Vinci kept in the Biblioteca Ambrosiana in Milan, some investigations have been carried out to verify the presence of microorganisms, such as bacteria and fungi. To verify the presence of microorganisms a noninvasive method of sampling has been used that was efficient and allowed us to highlight the microbial facies of the material that was examined using conventional microbiological techniques. The microclimatic conditions in the storage room as well as the water content of the volume were also assessed. The combined observations allowed the conclusion that the discoloration of suspected biological origin on some pages of AC is not related to the presence or current attack of microbial agents.

    The present study was conducted to examine whether the thumb rule of Leonardo da Vinci could be an objective method in the determination of the natural and artistic proportions of human face. In this study, a sample of 400 subjects (200 male and 200 female, 22-25 years old) was used. Measurements were made of the length of thumb, the length of ear, the approximate distances between the hair line and the glabella or eyebrows, between the glabella or eyebrows and the tip of the nose and the distance between the nose and the chin, and the distance between the ear and the lateral aspect of the eye. The results obtained in the males and females showed significant (p < 0.01) correlations between the length of thumb and the proportions of the face examined in the study. Additionally, the height of the face was found to be almost three times the length of the thumb. However, the measurements obtained from female subjects were on average smaller than those taken from males. The results obtained in this experiment could be of value in understanding of the evaluation of the face for the people working in plastic surgery or art. PMID:8782316

    Purpose To report our initial clinical cases of robotic laparoendoscopic single-site (R-LESS) partial nephrectomy (PN) performed with the use of the novel Da Vinci R-LESS platform. Materials and Methods Three patients underwent R-LESS PN from November 2013 through February 2014. Perioperative and postoperative outcomes were collected and intraoperative difficulties were noted. Results Operative time and estimated blood loss volume ranged between 100 and 110 minutes and between 50 and 500 mL, respectively. None of the patients was transfused. All cases were completed with the off-clamp technique, whereas one case required conversion to the conventional (multiport) approach because of difficulty in creating the appropriate scope for safe tumor resection. No major postoperative complications occurred, and all tumors were resected in safe margins. Length of hospital stay ranged between 3 and 7 days. The lack of EndoWrist movements, the external collisions, and the bed assistant's limited working space were noticed to be the main drawbacks of this surgical method. Conclusions Our initial experience with R-LESS PN with the novel Da Vinci platform shows that even though the procedure is feasible, it should be applied in only appropriately selected patients. However, further improvement is needed to overcome the existing limitations. PMID:24955221

    The author discusses a previously unknown early sixteenth-century renaissance handmade anatomical miniature skull. The small, naturalistic skull made from an agate (calcedonia) stone mixture (mistioni) shows remarkable osteologic details. Dr. Saban was the first to link the skull to Leonardo. The three-dimensional perspective of and the search for the senso comune are discussed. Anatomical errors both in the drawings of Leonardo and this skull are presented. The article ends with the issue of physiognomy, his grotesque faces, the Perspective Communis and his experimenting c. 1508 with the stone mixture and the human skull. Evidence, including the Italian scale based on Crazie and Braccia, chemical analysis leading to a mine in Volterra and Leonardo's search for the soul in the skull are presented. Written references in the inventory of Salai (1524), the inventory of the Villa Riposo (Raffaello Borghini 1584) and Don Ambrogio Mazenta (1635) are reviewed. The author attributes the skull c. 1508 to Leonardo da Vinci. PMID:24853982

  2. How did Leonardo perceive himself? Metric iconography of da Vinci's self-portraits

    Some eighteen portraits are now recognized of Leonardo in old age, consolidating the impression from his bestestablished self-portrait of an old man with long white hair and beard. However, his appearance when younger is generally regarded as unknown, although he was described as very beautiful as a youth. Application of the principles of metric iconography, the study of the quantitative analysis of the painted images, provides an avenue for the identification of other portraits that may be proposed as valid portraits of Leonardo during various stages of his life, by himself and by his contemporaries. Overall, this approach identifies portraits of Leonardo by Verrocchio, Raphael, Botticelli, and others. Beyond this physiognomic analysis, Leonardo's first known drawing provides further insight into his core motivations. Topographic considerations make clear that the drawing is of the hills behind Vinci with a view overlooking the rocky promontory of the town and the plain stretching out before it. The outcroppings in the foreground bear a striking resemblance to those of his unique composition, 'The Virgin of the Rocks', suggesting a deep childhood appreciation of this wild terrain. and an identification with that religious man of the mountains, John the Baptist, who was also the topic of Leonardo's last known painting. Following this trail leads to a line of possible selfportraits continuing the age-regression concept back to a self view at about two years of age.

  3. The mother relationship and artistic inhibition in the lives of Leonardo da Vinci and Erik H. Erikson.

    PubMed

    2008-12-01

    In four earlier articles, I focused on the theme of the relationship of melancholia and the mother, and suggested that the melancholic self may experience humor (Capps, 2007a), play (Capps, 2007b), dreams (Capps, 2008a), and art (Capps, 2008b) as restorative resources. I argued that Erik H. Erikson found these resources to be valuable remedies for his own melancholic condition, which had its origins in the fact that he was illegitimate and was raised solely by his mother until he was three years old, when she remarried. In this article, I focus on two themes in Freud's Leonardo da Vinci and a memory of his childhood (1964): Leonardo's relationship with his mother in early childhood and his inhibitions as an artist. I relate these two themes to Erikson's own early childhood and his failure to achieve his goal as an aspiring artist in his early twenties. The article concludes with a discussion of Erikson's frustrated aspirations to become an artist and his emphasis, in his psychoanalytic work, on children's play. PMID:19093682

    The increased distance between surgeon and surgical field is a significant problem in laparoscopic surgery. Robotic surgery, although providing advantages for the operator, increases this gap by completely removing force feedback. Enhancement with visual tools can therefore be beneficial. The goal of this preliminary work was to create a custom plugin for OsiriX to display volume-rendered images in the da Vinci surgeon's console. The TilePro multi-input display made the generated stereoscopic pairs appear to have depth. Tumor position, vascular supply, spatial location, and relationship between organs appear directly within the surgeon's field of view. This study presents a case of totally robotic right colectomy for cancer using this new technology. Sight diversion was no longer necessary. Depth perception was subjectively perceived as profitable. Total immersion in the operative field helped compensate for the lack of tactile feedback specific to robotic intervention. This innovative tool is a step forward toward augmented-reality robot-assisted surgery. PMID:22549904

    Introduction: While the effects of increasing body mass index on prostate cancer epidemiology and surgical approach have recently been studied, its effects on surgical outcomes are less clear. We studied the perioperative outcomes of obese (BMI >= 30) men treated with daVinci-assisted laparoscopic radical prostatectomy (DLP) and compared them to those treated with open radical retropubic prostatectomy (RRP) in a contemporary time frame. Method: After Institutional Review Board approval, we used the Mayo Clinic Radical Prostatectomy database to identify patients who had undergone DLP by a single surgeon and those who had undergone open RRP by a single surgeon between December 2002 and March 2005. Baseline demographics, peri- and post-operative courses, and complications were collected by retrospective chart review, and variables from the two cohorts compared using chi-square method and least-squares method of linear regression where appropriate. Results: 59 patients who had DLP and 76 undergoing RRP were available for study. Baseline demographics were not statistically different between the two cohorts. Although DLP had a significantly lower clinical stage than RRP (p=0.02), pathological stage was not statistically different (p=0.10). Transfusion rates, hospital stay, overall complications, and pathological Gleason were also not significantly different, nor were PSA progression, positive margin rate, or continence at 1 year. After bilateral nerve-sparing, erections suitable for intercourse with or without therapy at 1 year was 88.5% (23/26) for DLP and 61.2% (30/49) for RRP (p=0.01). Follow-up time was similar. Conclusion: For obese patients, DLP appears to have similar perioperative, as well as short-term oncologic and functional outcomes when compared to open RRP.

    The Very Large Telescope Interferometer (VLTI) is a complex system, made of a large number of separated elements. To prepare an early successful operation, it will require a period of extensive testing and verification to ensure that the many devices involved work properly together, and can produce meaningful data. This paper describes the concept chosen for the VLTI commissioning instrument, LEONARDO da VINCI, and details its functionalities. It is a fiber based two-way beam combiner, associated with an artificial star and an alignment verification unit. The technical commissioning of the VLTI is foreseen as a stepwise process: fringes will first be obtained with the commissioning instrument in an autonomous mode (no other parts of the VLTI involved); then the VLTI telescopes and optical trains will be tested in autocollimation; finally fringes will be observed on the sky.

    Surgery to transfer the axillary nerve and the nerve of the long head of the triceps presents two obstacles: 1) the access portals are not standardized and 2) the nerves are for their larger part approached through large incisions. The goal of this study was to explore the feasibility of an endoscopic microsurgical approach. The posterior aspect of a cadaver shoulder was approached through three communicating mini-incisions. The Da Vinci robot camera was installed on a central trocart, and the instrument arms on the adjacent trocarts. A gas insufflation distended the soft tissues up to the lateral axillary space. The branches of the axillary nerve and the nerve to the long head of the triceps brachii muscle were identified. The dissection of the axillary nerve trunk and its branches was easy. The posterior humeral circumflex veins and artery were dissected as well without any difficulty. Finding the nerve to the long head of the triceps brachii was found to be more challenging because of its deeper location. Robots properties allow performing conventional microsurgery: elimination of the physiologic tremor and multiplication of the movements. They also facilitate the endoscopic approach of the peripheral nerves, as seen in our results on the terminal branches of the axillary nerve and the nerve to the long head of the triceps brachii.

    We compare the first direct angular diameter measurements obtained on our closest stellar neighbour, Alpha Centauri, to recent model diameters constrained by asteroseismic observations. Using the VINCI instrument installed at ESO's VLT Interferometer (VLTI), the angular diameters of the two main components of the system, Alpha Cen A and B, were measured with a relative precision of 0.2% and 0.6%, respectively. Particular care has been taken in the calibration of these measurements, considering that VINCI is estimating the fringe visibility using a broadband K filter. We obtain uniform disk angular diameters for Alpha Cen A and B of UD[A] = 8.314 +/- 0.016 mas and UD[B] = 5.856 +/- 0.027 mas, and limb darkened angular diameters of LD[A] = 8.511 +/- 0.020 mas and LD[B] = 6.001 +/- 0.034 mas. Combining these values with the parallax from Soderhjelm (1999), we derive linear diameters of D[A] = 1.224 +/- 0.003 Dsun and D[B] = 0.863 +/- 0.005 Dsun. These values are compatible with the masses published by Thevenin et al.(2002) for both stars.

    First Instruments for the VLT Interferometer Summary A few months from now, light from celestial objects will be directed for the first time towards ESO's Very Large Telescope Interferometer (VLTI) at the Paranal Observatory (Chile). During this "First Light" event and the subsequent test phase, the light will be recorded with a special test instrument, VINCI (VLT INterferometer Commissioning Instrument). The main components of this high-tech instrument are aptly named MONA (a system that combines the light beams from several telescopes by means of optical fibers) and LISA (the infrared camera). VINCI was designed and constructed within a fruitful collaboration between ESO and several research institutes and industrial companies in France and Germany . It is now being assembled at the ESO Headquarters in Garching (Germany) and will soon be ready for installation at the telescope on Paranal. With the VLTI and VINCI, Europe's astronomers are now entering the first, crucial phase of an exciting scientific and technology venture that will ultimately put the world's most powerful optical/IR interferometric facility in their hands .

It will later be installed in "clean-room" conditions within the Interferometric Laboratory at the Paranal Observatory. This electronic photo was obtained for documentary purposes. VINCI (VLT INterferometer Commissioning Instrument) is the "First Light" instrument for the Very Large Telescope Interferometer (VLTI) at the Paranal Observatory (Chile). Early in 2001, it will be used for the first tests of this very complex system. Subsequently, it will serve to tune this key research facility to the highest possible performance. The VLTI is based on the combination of light (beams) from the telescopes at Paranal. Of these, the four 8.2-m Unit Telescopes are already in operation - they will soon be joined by three 1.8-m telescopes that can be relocated on rails, cf. PR Photo 43b/99. By means of a system of mirrors, the light from two or more of these telescopes will be guided to the central Interferometric Laboratory , at the center of the observing platform on Paranal. Information about the heart of this complex system, the Delay Lines that are located in the underground Interferometric Tunnel, is available with the recent ESO PR Photos 26a-e/00. The VLTI will later receive other front-line instruments, e.g. AMBER , MIDI and PRIMA. When fully ready some years from now, the VLTI will produce extremely sharp images. This will have a major impact on different types of exciting astronomical observations, e.g.: * the direct discovery and imaging of extra-solar planets comparable to Jupiter, * the discovery and imaging of low-mass stars such as brown dwarfs, * observations of star-forming regions and to better understand the physical processes that give birth to stars, * spectral analysis of the atmospheres of nearby stars, and * imaging the objects of the very core of our Galaxy and the detection of black holes in active nuclei of galaxies. The VINCI test instrument The new instrument, VINCI , will soon be delivered to Paranal by the Département de Recherche Spatiale (Department for Space Research), a joint unit of the Centre Nationale de la Recherche Scientifique (French National Centre for Scientific Research) and the Paris Observatory. VINCI is a functional copy of the FLUOR instrument - now at the IOTA (Infrared Optical Telescope Array) interferometer - that has been upgraded and adapted to the needs of the VLTI. FLUOR was developed by the Département de Recherche Spatiale (DESPA) of the Paris Observatory. It was used in 1991 at

    2002-01-01

    The purpose of this paper is to present the major results of the VINCI engine development program at mid-2002. The VINCI engine will power the Ariane 5 ESC-B upper stage and will contribute to provide a 12 t payload capability in geo-stationary transfer orbit to the Ariane 5 launch system. It will also provide a multiple firing capability and therefore the potential to perform a broad array of missions. The VINCI engine is a cryogenic expander cycle engine combining the required features of this cycle, i.e. high performance chamber cooling and high performance hydrogen turbopump, with proven design concepts based on the accumulated experience from previous European cryogenic engines such as the HM7 and the Vulcain. High performance along with a constant focus on reliability, low cost and simplicity of architecture are the design goals of the VINCI program. The proposed paper will recall how the engine design choices were made taking into account these sometimes potentially conflicting criteria and using design to cost methods. The paper will also present the major achievements of the program over the 2001 - 2002 period, i.e. the completion of the engine detailed design, the manufacturing of the first subsystems, the first component and subsystem tests.

    PubMed

    Ciseri, Lorenzo Montemagno

    2014-01-01

    This article analyses Leonardo's interest in monsters and deformed reality, one of the lesser known aspects of his vast and multifaceted output. With the possible exception of his studies of physiognomy, relevant drawings, sketches and short stories represent a marginal aspect of his work, but they are nevertheless significant for historians of teratology. The purpose of this study is to provide a broad overview of the relationship between Leonardo and both the literature on mythological monsters and the reports on monstrous births that he either read about or witnessed personally. While aspects of his appreciation and attention to beauty and the pursuit of perfection and good proportions are the elements most emphasised in Leonardo's work, other no less interesting aspects related to deformity have been considered of marginal importance. My analysis will demonstrate that Leonardo approached the realm of monstrosity as if he considered abnormality a mirror of normality, deformity a mirror of harmony, and disease a mirror of health, as if to emphasise that, ultimately, it is the monster that gives the world the gift of normality. Two special cases of monstrosity are analysed: the famous monster of Ravenna, whose image was found among his papers, and a very rare case of parasitic conjoined twins (thoracopagus parasiticus) portrayed for the first time alive, probably in Florence, by Leonardo himself.

She was operated through a 2 cm long single midline umbilical incision using a new platform from Intuitive Surgical. The operative time was 45 minutes and the docking time was 15 minutes. Ovarian cystectomy using the da Vinci single-port system is feasible and effective. This new semi-rigid robotic surgery platform may increase access to the potential advantages of single-site surgery. Robotic systems designed specifically for single port approach have the potential of alleviating several of the limitations associated with traditional laparoscopic single-site surgery.

In the last few years this has led to strong promotion of the view that Panum's case is not based on a stereoscopic process involving double fusion, that only one line is fused, with the depth of the other one attributable either to fixation disparity or to occlusion cues. This view is refuted in two ways. First it is shown that when the separation of the two lines, considered as a disparity, is within the range of 'patent stereopsis', depth is perceived with a precision and accuracy indistinguishable from regular stereopsis. The predictions of nonstereoscopic theories concerning the effects of fixation are not borne out at small disparities. Second, very compelling Panum versions of orientation and curvature disparity are introduced, which are difficult to account for except by a process of double fusion. Finally it is shown that at large disparities the depth in Panum's case deviates from prediction more frequently than does regular stereoscopic depth. PMID:7617433

    This report describes a pair of brief, interactive classroom exercises utilizing Renaissance artists’ depictions of the brain to help increase student interest in learning basic neuroanatomy. Undergraduate students provided anonymous quantitative evaluations of both exercises. The feedback data suggest that students found both exercises engaging. The data also suggest that the first exercise increased student interest in learning more about neuroanatomy in general, while the second provided useful practice in identifying major neuroanatomical structures. Overall, the data suggest that these exercises may be a useful addition to courses that introduce or review neuroanatomical concepts. PMID:23805058

    The security challenges faced by users of the grid are considerably different to those faced in previous environments. The adoption of pilot jobs systems by LHC experiments has mitigated many of the problems associated with the inhomogeneities found on the grid and has greatly improved job reliability; however, pilot jobs systems themselves must then address many security issues, including the execution of multiple users' code under a common 'grid' identity. In this paper we describe the improvements and evolution of the security model in the ATLAS PanDA (Production and Distributed Analysis) system. We describe the security in the PanDA server which is in place to ensure that only authorized members of the VO are allowed to submit work into the system and that jobs are properly audited and monitored. We discuss the security in place between the pilot code itself and the PanDA server, ensuring that only properly authenticated workload is delivered to the pilot for execution. When the code to be executed is from a 'normal' ATLAS user, as opposed to the production system or other privileged actor, then the pilot may use an EGEE developed identity switching tool called gLExec. This changes the grid proxy available to the job and also switches the UNIX user identity to protect the privileges of the pilot code proxy. We describe the problems in using this system and how they are overcome. Finally, we discuss security drills which have been run using PanDA and show how these improved our operational security procedures.

    DART Bootstrap Services (dbs) is the first component of run-control for the DART Data Acquisition system -- the DA for the 96` round of experiments at Fermilab -- though it has potential usefulness as a powerful tool in other distributed applications. dbs is an rlogin session multiplexer. It allows a user, running a single program, to start up any number of remote login sessions, feed shell commands to them, and collect their output into a single (or multiple) log files (a server keeps the sessions open and collects their output). From this program, any session can be attached to interactively so it appears just like an rlogin session -- dbs becomes transparent. When finished with this interactive mode, the user can escape back to dbs and attach to a different session if so desired. Among many other useful features, dbs supplies a mechanism for cleanup (deletion) of all processes created under a session, allowing a fresh start.

    The processes of defining managerial roles and providing for delegation of authority are essential to any enterprise. At most large organizations, these processes are defined in policy manuals and through sets of standard operating procedures for many, if not all, business and administrative functions. Many of these staff-initiated, administrative functions require the routing of documents for approval to one or more levels of management. These employee-oriented, back office types of workflows tend to require more flexibility in determining to whom these documents should go to, while, at the same time, providing the responsible parties with the flexibility to delegate their approval authority or allow others to review their work. Although this practice is commonplace in manual, paper-based processes that exist in many organizations, it is difficult to provide the same flexibility in the more structured, electronic-based, workflow systems.

    The LHC experiments are today at the leading edge of large scale distributed data-intensive computational science. The LHC's ATLAS experiment processes data volumes which are particularly extreme, over 140 PB to date, distributed worldwide at over of 120 sites. An important element in the success of the exciting physics results from ATLAS is the highly scalable integrated workflow and dataflow management afforded by the PanDA workload management system, used for all the distributed computing needs of the experiment. The PanDA design is not experiment specific and PanDA is now being extended to support other data intensive scientific applications. PanDA was cited as an example of "a high performance, fault tolerant software for fast, scalable access to data repositories of many kinds" during the "Big Data Research and Development Initiative" announcement, a 200 million USD U.S. government investment in tools to handle huge volumes of digital data needed to spur science and engineering discoveries.

Expert systems will aid in the performance of the quality assurance and data accounting functions of the two SLDPF functional elements: the Spacelab Input Processing System (SIPS) and the Spacelab Output Processing System (SOPS). Prototypes were developed for each as independent efforts. The SIPS Knowledge System Prototype (KSP) used the commercial shell OPS5+ on an IBM PC/AT; the SOPS Expert System Prototype used the expert system shell CLIPS implemented on a Macintosh personal computer. Both prototypes emulate the duties of the respective QA/DA analysts based upon analyst input and predetermined mission criteria parameters, and recommended instructions and decisions governing the reprocessing, release, or holding for further analysis of data. These prototypes demonstrated feasibility and high potential for operational systems. Increase in productivity, decrease of tedium, consistency, concise historial records, and a training tool for new analyses were the principal advantages. An operational configuration, taking advantage of the SLDPF network capabilities, is under development with the expert systems being installed on SUN workstations. This new configuration in conjunction with the potential of the expert systems will enhance the efficiency, in both time and quality, of the SLDPF's release of Spacelab/AST data products.

    The electronic instrumentation of the Large Hadron Collider (LHC) cryogenic system is expected to receive a large radiation dose (>10 13 n cm -2 and 1-2 kGy (Si)) within 10 years of activity so all the electronic devices should tolerate this radiation level without a significant degradation. This paper focuses on the selection of a radiation tolerant 12-bit parallel input D/A converter suitable for the signal conditioners for cryogenic thermometry in the LHC. During an initial campaign, some candidate converters were irradiated to determine the most tolerant device. Once this was determined, a massive test was carried out. Some weak points of the selected device were addressed through the use of an external voltage source and a radiation tolerant operational amplifier. The tests show that a system consisting of an AD565 D/A converter, coupled to an external voltage reference and an OPA627 operational amplifier can tolerate a total radiation dose up to 5×10 13 n cm -2 and 2100 Gy (Si), thus satisfying the requirements set by CERN.

It supports initializing the front end data acquisition hardware, queueing and processing readout activation signals, cleaning up at the end of data acquisition, and transferring configuration parameters and statistical data between a ''Host'' computer and the readout processes. FEREAD is implemented as part of the PAN-DA software system and is designed to run on any Motorola 68k based processor board. It has been ported to the FASTBUS General Purpose Master (GPM) interface board and the VME MVME133A processor board using the pSOS/Microtec environment. 12 refs., 2 figs.

    As the main scientific tool at the Nuclear Research Institute (NRI), the Da Lat Nuclear Research Reactor is playing a special role in the development of nuclear application in Viet Nam. Reconstructed from the previous TRIGAMARK II, it has been operating since, 1984, totalling 13,500 hrs. Since November 1992 it has undergone a general inspection followed by a complete refurbishment in response to technical requirement for ensuring its reliability and safety. The reactor, shut down for main inspection and refurbishment tasks until March 1993, was put into operation alternately with the remaining refurbishment works. In pullet the renovation of its control and instrumentation system has been carried out. This has been thought necessary due to spare part procurement problems and the need to modernize the system for improving its reliability. Finally, a programme for reloading the reactor core is being implemented, in order to increase its reserve reactivity.

    Antibodies binding components of the Ro/La (or SSA/SSB) ribonucleoprotein particle are found in the sera of patients with systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS) as well as mothers who give birth to babies with neonatal lupus. Anti-La occurs in a subset of sera that contain anti-Ro, and anti-La is found more commonly in sera of patients with SS than in sera from SLE patients. The fine specificity of autoantibodies binding 60 kDa has been studied extensively. Recent data have suggested that there are disease-specific epitopes which identify patients with either SLE or SS. Alternatively, other data suggest that the B cell epitopes of 60kDa Ro vary according to the presence of anti-La. The present study was undertaken to determine whether binding of putative disease-specific 60 kDa Ro epitopes is associated with the diagnosis of SLE vs SS, or instead associated with the presence of anti-La. Anti-60 kDa Ro positive sera from 24 SLE patients and 44 SS patients were studied for antibodies binding two epitopes of 60 kDa Ro. We find the epitope defined by residues 171-190 is associated with anti-60 kDa Ro without anti-La, regardless of diagnosis. Meanwhile, binding of the epitope defined by residues 215-232 is not commonly found in anti-60 kDa Ro sera, especially in those sera with both anti-60 kDa Ro and anti-La. Thus, the fine specificity of antibody binding to 60 kDa Ro varies according to the presence of anti-La, not to the diagnosis of either SLE or SS. PMID:11530996

    Cerebrospinal fluid (CSF) serves buoyancy. The buoyancy thought to play crucial role in many aspects of the central nervous system (CNS). Weightlessness is produced mainly by the CSF. This manuscript is purposely made to discuss its significance which thought contributing towards an ideal environment for the CNS to develop and function normally. The idea of microgravity environment for the CNS is supported not only by the weightlessness concept of the brain, but also the noted anatomical position of the CNS. The CNS is positioned in bowing position (at main cephalic flexure) which is nearly similar to an astronaut in a microgravity chamber, fetus in the amniotic fluid at early gestation, and animals and plants in the ocean or on the land. Therefore, this microgravity position can bring us closer to the concept of origin. The hypothesis on 'the origin' based on the microgravity were explored and their similarities were identified including the brainwaves and soul. Subsequently a review on soul was made. Interestingly, an idea from Leonardo da Vinci seems in agreement with the notion of seat of the soul at the greater limbic system which has a distinctive feature of "from God back to God".

    Recent growth of daVinci Robotic Surgical System as a minimally invasive surgery tool has led to a call for better training of future surgeons. In this paper, a new virtual reality simulator, called RoSS is presented. Initial results from two studies - face and content validity, are very encouraging. 90% of the cohort of expert robotic surgeons felt that the simulator was excellent or somewhat close to the touch and feel of the daVinci console. Content validity of the simulator received 90% approval in some cases. These studies demonstrate that RoSS has the potential of becoming an important training tool for the daVinci surgical robot.

    This research represents a randomized blinded pilot study to evaluate the acceptability and validity of a da Vinci robotic virtual reality simulator platform tested during a pediatric robotic surgery post-graduate course during the annual American Urological Association meeting in June 2007. Course enrollees performed robotic skills tasks on the da Vinci robot and on an offline dV-Trainer and course participant demographic and performance data were analyzed. The majority of learners believed that VR simulation is useful for teaching robotic skills, they believed that the offline trainer can teach robotic skills comparable to a dry lab robotics skills station, and the offline trainer was able to discriminate between experts and novices of robotic surgery, thereby meeting criteria for face, content, and construct validities. This is the first reported acceptability study of a VR robotic surgery simulator as compared to the da Vinci robot system. PMID:18391295

In 1489, da Vinci began investigating human anatomy, including an examination of human tendons, muscles, and the skeletal system. He continued this line of inquiry later in life, identifying what he called ?the four powers?movement, weight, force, and percussion??and how he thought they worked in the human body. His approach, by the way, was very modern?analyzing nature through anatomy, developing models for interpretation, and transferring this knowledge to bio-inspired machines. PMID:26186054

    A method of generating a multi-band spectrum is proposed using a digital-to-analog (D/A) converter. The multi-band spectrum is useful for the slow-beam-extraction from a synchrotron using the method of radio frequency (RF)-knockout. Data for the spectrum are calculated in advance to be saved in the memory of a D/A converter, and are output synchronized with external clocks. An experiment showed that a multi-band spectrum of 10 bands could be generated with a total bandwidth of about 16.4 MHz and each bandwidth less than 45 kHz. Beam simulation with this method showed that an RF signal from a D/A converter could be effectively used for the control of uniform spill structure.

    We have analyzed antibody (Ab) reactivities of patients with limited systemic sclerosis (SSc) and anti-centromere Ab, patients with diffuse SSc and anti-topoisomerase 1 (anti-topo 1) Ab, patients with diffuse SSc without anti-topo 1 or anti-centromere Ab and age- and gender-matched healthy controls with normal human tissue and endothelial cell (EC) antigens. IgG reactivities with tissue antigens differed significantly between patients with anti-topo 1 Ab and patients with anti-centromere Ab. One 100-kDa band identified as topoisomerase 1 in macrovascular and microvascular EC extracts was recognized by IgG from patients with anti-topo 1 Ab and 50% of patients without specific Ab. IgG from patients with limited SSc and anti-centromere Ab, but not those of other patients or controls specifically recognized a 80-kDa band only in microvascular EC. Our results indicate that Ab from patients with limited or diffuse SSc with or without anti-topo 1 Ab exhibit specific and mutually exclusive reactivity patterns. PMID:15183145

    The value of laparoscopic surgery for rectal cancer is still controversially discussed. Robotics offers the opportunity to leave the limitations of conventional laparoscopy behind us. The three-dimensional visualization and the superior dexterity by wristed instruments should be particularly helpful in complex laparoscopic procedures in confined spaces such as the small pelvis. Colorectal resections using the Da Vinci® system are well established and becoming increasingly more standard procedures. Nerve-sparing total mesorectal excision in patients with rectal cancer, total mesocolic excision in patients with right-sided colon cancer and rectopexy in patients with pelvic floor insufficiency are the most promising indications. The prospective randomized ROLARR study has been evaluating the application of the Da Vinci® system in laparoscopic rectal cancer surgery since 2011. Besides the currently available clinical data the perioperative and intraoperative logistics and strategy will be presented in detail. PMID:23942962

    After more than a decade of development, the role of robotic rectal cancer surgery has been established. However robotic right hemicolectomy has just commenced. For rectal cancer surgery, the Da Vinci system is more flexible, accurate, and stable than traditional laparoscopy. The robotic surgery is safe and efficient, and protects the pelvic autonomic nerve function better. At the same time, robotic surgery is easy to learn, promoting its popularization. In robotic right hemicolectomy, the surgery suitable for Da Vinci system is also improved. Da Vinci system is not perfect. High cost is a major obstacle to the wide applications. Lack of tactile feedback and limited mobility of robotic arms also should not be ignored. The next generation of robotic system may make up for these deficiencies through a number of new technologies. The combination of robotics with single port laparoscopic techniques and multi-organ resections is expected to expand the advantages of robotic surgery in colorectal cancer and promote its development.

    The tobacco mosaic virus (TMV) replicase complex contains virus- and host-encoded proteins. In tomato, one of these host proteins was reported previously to be related serologically to the GCD10 subunit of yeast eIF-3. The yeast two-hybrid system has now been used to show that yeast GCD10 interacts selectively with the methyltransferase domain shared by the 126 and 183 kDa TMV replicase proteins. These findings are consistent with a role for a GCD10-like protein in the TMV replicase complex and suggest that, in TMV-infected cells, the machinery of virus replication and protein synthesis may be closely connected.

    Many methods for microvascular anastomoses exist, including use of magnifying loupes (x 2.5, x 3.5, x 4.5, x 6), but the operating microscope remains the gold standard. The authors present the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA) as an alternative method for performing microvascular anastomoses. The da Vinci robot has fully articulating microinstruments with six degrees of freedom, the ability to filter tremor, the capability to perform telesurgery, and the advantage of 3-D visualization. It offers full and dynamic control over the operating camera, allowing variable positioning and the ability to scale down movements. Its drawbacks include initial high cost, lack of haptic feedback, decreased participation of the first assistant, and lack of widespread availability. In this feasibility study, multiple microanastomoses were performed in canine tarsal and superficial femoral vessels. PMID:16425123

    Innovative techniques have a really magical attraction for physicians as well as for patients. The number of robotic-assisted procedures worldwide has almost tripled from 80,000 procedures in the year 2007 to 205,000 procedures in 2010. In the same time the total number of Da Vinci surgery systems sold climbed from 800 to 1,400. Advantages, such as three-dimensional visualization, a tremor-filter, an excellent instrument handling with 6 degrees of freedom and better ergonomics, together with aggressive marketing led to a veritable flood of new Da Vinci acquisitions in the whole world. Many just took the opportunity to introduce a new instrument to save a long learning curve and start immediately in the surgical master class.If Da Vinci sacrocolpopexy is compared with the conventional laparoscopic approach, robotic-assisted sacrocolpopexy shows a significantly longer duration of the procedure, a higher need for postoperative analgesics, much higher costs and an identical functional outcome without any advantage over the conventional laparoscopic approach. Although the use of robotic-assisted systems shows a significantly lower learning curve for laparoscopic beginners, it only shows minimal advantages for the experienced laparoscopic surgeon. Therefore it remains uncertain whether robotic-assisted surgery shows a significant advantage compared to the conventional laparoscopic surgery, especially with small reconstructive laparoscopic procedures such as sacrocolpopexy.

    Previously, we generated attenuated variants of pepper mild mottle virus by replacing residue 649 in the 126-kDa replicase protein with various amino acids. Here, we examined the biological properties of the 16 variants that caused either mild mosaic or no mosaic. All but one (A649N) of the mild-mosaic-inducing strains replicated at higher levels in pepper plants and systemically moved at higher rates into the upper non-inoculated leaves than the no-mosaic strains. C1421, previously selected for practical use, not only caused mild symptoms but also had an especially high replication rate in pepper plants and spread more efficiently into the upper non-inoculated leaves.

    The Production and Distributed Analysis System (PanDA) plays a key role in the ATLAS distributed computing infrastructure. All ATLAS Monte-Carlo simulation and data reprocessing jobs pass through the PanDA system. We will describe how PanDA manages job execution on the grid using dynamic resource estimation and data replication together with intelligent brokerage in order to meet the scaling and automation requirements of ATLAS distributed computing. PanDA is also the primary ATLAS system for processing user and group analysis jobs, bringing further requirements for quick, flexible adaptation to the rapidly evolving analysis use cases of the early datataking phase, in addition to the high reliability, robustness and usability needed to provide efficient and transparent utilization of the grid for analysis users. We will describe how PanDA meets ATLAS requirements, the evolution of the system in light of operational experience, how the system has performed during the first LHC data-taking phase and plans for the future.

  12. Functions of the 126- and 183-kDa proteins of tobacco mosaic virus.

    PubMed

    Lewandowski, D J; Dawson, W O

    2000-05-25

    Tobacco mosaic virus produces two proteins that contain domains similar to the methyltransferase (MT) and helicase (HEL)-like domains of the replicase-associated proteins of other RNA viruses. The more abundant 126-kDa protein contains only the MT and HEL-like domains, whereas the 183-kDa readthrough protein additionally contains the polymerase domain. We examined the functions of these proteins by constructing a bipartite system to express the 126- and 183-kDa proteins from separate RNAs. Mutants expressing the 183-kDa protein recognized promoters for negative- and positive-stranded RNA synthesis, transcribed subgenomic mRNAs, capped RNAs, synthesized proteins, moved cell to cell within the plant, and replicated defective RNAs (dRNAs). The principal function of the 126-kDa protein was to increase the rate of replication approximately tenfold. The 126-kDa protein appeared to function primarily in cis, and production of the 126-kDa protein in trans did not enhance replication of the helper virus. dRNAs producing a functional 126-kDa protein were replicated efficiently by helper viruses that produced only the 183-kDa protein but not by wild-type virus, suggesting that efficient replication required the 183-kDa protein to form a heterodimer with the 126-kDa protein already bound to the target dRNA.

    Background and Objectives: Our objectives were to compare the utility of learning a suturing task on the virtual reality da Vinci Skills Simulator versus the da Vinci Surgical System dry laboratory platform and to assess user satisfaction among novice robotic surgeons. Methods: Medical trainees were enrolled prospectively; one group trained on the virtual reality simulator, and the other group trained on the da Vinci dry laboratory platform. Trainees received pretesting and post-testing on the dry laboratory platform. Participants then completed an anonymous online user experience and satisfaction survey. Results: We enrolled 20 participants. Mean pretest completion times did not significantly differ between the 2 groups. Training with either platform was associated with a similar decrease in mean time to completion (simulator platform group, 64.9 seconds [P = .04]; dry laboratory platform group, 63.9 seconds [P < .01]). Most participants (58%) preferred the virtual reality platform. The majority found the training “definitely useful” in improving robotic surgical skills (mean, 4.6) and would attend future training sessions (mean, 4.5). Conclusion: Training on the virtual reality robotic simulator or the dry laboratory robotic surgery platform resulted in significant improvements in time to completion and economy of motion for novice robotic surgeons. Although there was a perception that both simulators improved performance, there was a preference for the virtual reality simulator. Benefits unique to the simulator platform include autonomy of use, computerized performance feedback, and ease of setup. These features may facilitate more efficient and sophisticated simulation training above that of the conventional dry laboratory platform, without loss of efficacy. PMID:23925015

  2. Hemispheric differences in the mesostriatal dopaminergic system

    2014-01-01

    The mesostriatal dopaminergic system, which comprises the mesolimbic and the nigrostriatal pathways, plays a major role in neural processing underlying motor and limbic functions. Multiple reports suggest that these processes are influenced by hemispheric differences in striatal dopamine (DA) levels, DA turnover and its receptor activity. Here, we review studies which measured the concentration of DA and its metabolites to examine the relationship between DA imbalance and animal behavior under different conditions. Specifically, we assess evidence in support of endogenous, inter-hemispheric DA imbalance; determine whether the known anatomy provides a suitable substrate for this imbalance; examine the relationship between DA imbalance and animal behavior; and characterize the symmetry of the observed inter-hemispheric laterality in the nigrostriatal and the mesolimbic DA systems. We conclude that many studies provide supporting evidence for the occurrence of experience-dependent endogenous DA imbalance which is controlled by a dedicated regulatory/compensatory mechanism. Additionally, it seems that the link between DA imbalance and animal behavior is better characterized in the nigrostriatal than in the mesolimbic system. Nonetheless, a variety of brain and behavioral manipulations demonstrate that the nigrostriatal system displays symmetrical laterality whereas the mesolimbic system displays asymmetrical laterality which supports hemispheric specialization in rodents. The reciprocity of the relationship between DA imbalance and animal behavior (i.e., the capacity of animal training to alter DA imbalance for prolonged time periods) remains controversial, however, if confirmed, it may provide a valuable non-invasive therapeutic means for treating abnormal DA imbalance.

    We propose a novel system for image guidance in totally endoscopic coronary artery bypass (TECAB). A key requirement is the availability of 2D-3D registration techniques that can deal with non-rigid motion and deformation. Image guidance for TECAB is mainly required before the mechanical stabilization of the heart, thus the most dominant source of non-rigid deformation is the motion of the beating heart. To augment the images in the endoscope of the da Vinci robot, we have to find the transformation from the coordinate system of the preoperative imaging modality to the system of the endoscopic cameras. In a first step we build a 4D motion model of the beating heart. Intraoperatively we can use the ECG or video processing to determine the phase of the cardiac cycle. We can then take the heart surface from the motion model and register it to the stereo-endoscopic images of the da Vinci robot using 2D-3D registration methods. We are investigating robust feature tracking and intensity-based methods for this purpose. Images of the vessels available in the preoperative coordinate system can then be transformed to the camera system and projected into the calibrated endoscope view using two video mixers with chroma keying. It is hoped that the augmented view can improve the efficiency of TECAB surgery and reduce the conversion rate to more conventional procedures.

    Purpose of review Robot-assisted laparoscopic surgery in urology has gained immense popularity with the Da Vinci system but a lot of research teams are working on new robots. The purpose of this paper is to review current urologic robots and present future developments directions. Recent findings Future systems are expected to advance in two directions: improvements of remote manipulation robots and developments of image-guided robots. Summary The final goal of robots is to allow safer and more homogeneous outcomes with less variability of surgeon performance, as well as new tools to perform tasks based on medical transcutaneous imaging, in a less invasive way, at lower costs. It is expected that improvements for remote system could be augmented reality, haptic feed back, size reduction and development of new tools for NOTES surgery. The paradigm of image-guided robots is close to a clinical availability and the most advanced robots are presented with end-user technical assessments. It is also notable that the potential of robots lies much further ahead than the accomplishments of the daVinci system. The integration of imaging with robotics holds a substantial promise, because this can accomplish tasks otherwise impossible. Image guided robots have the potential to offer a paradigm shift.

    2014-01-01

    During Run 1 at the Large Hadron Collider from 2009-2013, the ATLAS experiment successfully met the computing challenge of accumulating, managing and analyzing a volume of data now exceeding 140 PB, processed at over 100 sites around the world, and accessed by thousands of physicists. This accomplishment required nimbleness and flexibility in the distributed computing infrastructure, both hardware and software, as the operational computing model evolved during the run based on experience. A critical enabler for this evolution was PanDA, the ATLAS workload management system used for production and distributed analysis. PanDA's capabilities were utilized and extended to dynamically and intelligently distribute data and processing workloads across ATLAS resources based on data popularity and resource availability, thereby 'flattening' an originally hierarchical computing model, in order to use resources more efficiently. A new round of PanDA development now taking place will continue to evolve the model for bett...

    2011-01-01

    Although it has been almost a decade since the implementation of robotic colorectal surgery, this modality remains under development. The aim of this study is to briefly describe, based on a literature review, the current role of robotic surgery of the colon and rectum. This emerging technique has revealed some benefits such as an improvement in visualization in 3D, image magnification up to 10 times the actual size, and better maneuverability with wrist-like movements offered by the da Vinci® Surgical System. This system is composed of the robotic console in which the surgeon performs the movements to be accomplished by the robot. The latter presents up to three articulated arms for instrumentation as well as the camera arm. Even though the safety and feasibility of robotic colon surgery has been demonstrated, there is no complete manifestation of the advantages of this technique due to the wide surgical field in the abdominal cavity and freedom of movement achieved with other minimally invasive techniques. Robotic rectal surgery represents a different scenario since the advantages of the da Vinci® system are maximally expressed in the confined pelvic cavity. Consequently, in some specialized centers, the robotic modality represents the first therapeutic choice for resectable rectal cancer. Robotic-assisted laparoscopy has demonstrated to be a feasible and safe approach in colorectal surgery and presents some advantages over other techniques in regards to perioperative outcomes. Nonetheless, costs and availability represent the main limitations of this technology. PMID:21951893

    Molecular dynamics simulations were carried out to investigate the anionic structures of the molten CaO-SiO2-P2O5 system. The results show that the average first nearest-neighbor distances for Si-O and P-O pairs are 1.61 and 1.53 Å, respectively. As expected, above 98 pct P and 95 pct Si show fourfold coordination and form tetrahedral structures. Due to the high basicity, nonbridging oxygen occupies a predominant position in Si and P tetrahedron. Based on the oxygen number of different types, the structures of both Si and P tetrahedron were classified as Q 0, Q 1, Q 2, Q 3, and Q 4, where the superscript referred to the number of bridging oxygen atoms. With the substitution of P2O5 for SiO2, Q 0 decreased and other type of Q i units increased. For Si tetrahedron, Q 2 and Q 3 show most notable change, for P tetrahedron, Q 1and Q 2 show the most notable change. The change of Q i units for Si tetrahedron is larger than that for P tetrahedron. The concentration of free oxygen decreases remarkably with the increase of P2O5 content. The Si-O-P linkage is energetically more favorable than Si-O-Si and P-O-P linkages. P ion has a tendency to promote the polymerization of phosphosilicate melts.

    Robotic surgery was launched in Japan in 2000.In particular, the development of the da Vinci S Surgical System was a major breakthrough. It was introduced in Japan for the first time through our hospital in January 2009. Since then, the number of surgical robots used has been dramatically increasing, with up to approximately 160 robots all over the country. To date, we have performed more than 500 robotic surgeries, including 180 gastrectomies, at our hospital. Our data suggest that compared with the conventional laparoscopic approach, the use of the da Vinci Surgical System in minimally invasive gastrectomy for gastric cancer might improve short-term outcomes, particularly in terms of preventing postoperative local complications. Thus, we believe that use of surgical robots become increasingly beneficial for more extensive resections and operations that require more advanced skills, even though a couple of issues remain to be solved, such as long operative time, high cost, and limited experience and evidence. In this article, the current status and future perspectives regarding robotic gastrectomy for gastric cancer are presented based on our experience and a review of the literature. PMID:25434438

    The da Vinci S surgical system (Intuitive Surgical) was approved as a medical device in 2009 by the Japanese Ministry of Health, Labour and Welfare. Robotic surgery has since been used in gastrointestinal, thoracic, gynecological, and urological surgeries. In April 2012, robotic-assisted laparoscopic radical prostatectomy (RALP) was first approved for insurance coverage. Since then, RALP has been increasingly used, with more than 3,000 RALP procedures performed by March 2013. By July 2014, 183 institutions in Japan had installed the da Vinci surgical system. Other types of robotic surgeries are not widespread because they are not covered by public health insurance. Clinical trials using robotic partial nephrectomy and robotic gastrectomy for renal and gastric cancers, respectively, have recently begun as advanced medical treatments to evaluate health insurance coverage. These procedures must be evaluated for efficacy and safety before being covered by public health insurance. Other types of robotic surgery are being evaluated in clinical studies. There are several challenges in robotic surgery, including accreditation, training, efficacy, and cost. The largest issue is the cost-benefit balance. In this review, the current situation and a prospective view of robotic surgery in Japan are discussed. PMID:25763120

    Radical prostatectomy remains the standard treatment for long term cure of clinically localized prostate cancer, offering excellent oncologic outcomes, with cancer-specific survival approaching 95% at 15 years after surgery. The introduction of the "da Vinci Robotic Surgical System" (Intuitive Surgical, Sunnyvale, CA, USA) has been another important step toward a minimally invasive approach to radical prostatectomy. Technologic peculiarities, such as three-dimensional vision, wristed instrumentation with seven degrees of freedom of motion, lack of tremor, a 10x-magnification and a comfortable seated position for the surgeon has added value to the surgeon and patient. In this first part of a two article series, we describe preoperative patient preparation and positioning protocols for robot assisted radical prostatectomy (RARP) that are currently used in our institution (University of Montreal Hospital Center (CHUM)-Hopital St-Luc). We use the four-arm da Vinci Si Surgical System. Our experience with RARP is now over 250 cases with the senior surgeon having performed over 1200 RARPs and we have continually refined our technique to improve patient outcomes. PMID:24128839

    USF is a cellular factor involved in the transcriptional regulation of several cellular and viral promoters. Purified USF from HeLa cells (HeLa USF) consists of 43- and 44-kDa polypeptides which show independent binding to a specific DNA element. A cDNA encoding the 43-kDa species has been previously cloned. We show here that the purified form of bacterially expressed 43-kDa USF (i) exists in solution as a dimer whose formation is greatly favored under reducing conditions, (ii) binds to its cognate DNA sequence in a manner indistinguishable from that of HeLa USF, and (iii) is as efficient as HeLa USF in stimulating transcription from target promoters in a reconstituted cell-free system. Additional data indicate that the 44-kDa component of HeLa USF is immunologically unrelated to the 43-kDa polypeptide but is associated with it in HeLa cell extracts. These results suggest that the 43-kDa component possesses an intrinsic DNA binding and transcriptional activation potential and that the 44-kDa USF component of the natural USF complex may have some regulatory role.

    Our recent studies have shown that the difference in basal pain sensitivity to mechanical and thermal stimulation between Dark-Agouti (DA) rats and a novel congenic DA.1U rats is major histocompatibility complex (MHC) genes dependent. In the present study, we further used DA and DA.1U rats to investigate the role of MHC genes in formalin-induced pain model by behavioral, electrophysiological and immunohistochemical methods. Behavioral results showed biphasic nociceptive behaviors increased significantly following the intraplantar injection of formalin in the hindpaw of DA and DA.1U rats. The main nociceptive behaviors were lifting and licking, especially in DA rats (P<0.001 and P<0.01). The composite pain scores (CPS) in DA rats were significantly higher than those in DA.1U rats in both phases of the formalin test (P<0.01). Electrophysiological results also showed the biphasic increase in discharge rates of C and A? fibers of L5 dorsal root in the two strains, and the net change of the discharge rate of DA rats was significantly higher than that of DA.1U rats (P<0.05). The mechanical thresholds decreased after formalin injection in both strains (P<0.01), and the net change in the mechanical threshold in DA was greater than that in DA.1U rats (P<0.05). The expression of RT1-B, representation of MHC class II molecule, in laminae I-II of L4/5 spinal cord in DA rats was significantly higher than that in DA.1U rats in the respective experimental group (P<0.05). These results suggested that both DA and DA.1U rats exhibited nociceptive responses in formalin-induced pain model and DA rats were more sensitive to noxious chemical stimulus than DA.1U rats, indicating that MHC genes might contribute to the difference in pain sensitivity.

    Robotic surgery is a surgical procedure that adds a computer ?technology-enhanced device to the interaction between a surgeon and a patient during a surgical operation. This technology assumes a degree of control previously only reserved for the surgeon (Herron & Marohn, 2008). The surgeon sits at a console, typically in the operating room, directing and controlling the movements of one or more robotic arms. This technology has taken off in the United States during the past few years. Da Vinci® Surgical System, the leading robotic technology manufactured by Intuitive Surgical, Inc. (2014), has become the first robotic surgical platform commercially available in the United States to be cleared by the U.S. Food and Drug Administration. Use of robotic surgery has seen rapid growth. From 2007-2010, the number of robotic surgeries worldwide has almost tripled, and da Vinci robots have been installed in 1,400 hospitals in the United States, an increase of 75% (Barbash & Glied, 2010).?.

    Objective To discuss the feasibility of single-site robotic surgery for benign gynecologic tumors and early stage gynecologic cancers. Methods In this single institution, prospective analysis, we analyzed six patients who had undergone single-site robotic surgery between December 2013 and August 2014. Surgery was performed using the da Vinci Si Surgical System. Patient characteristics and surgical outcomes were analyzed. Results Single-site robotic surgery was performed successfully in all six cases. The median patient age was 48 years, and the median body mass index was 25.5 kg/m2 (range, 22 to 33 kg/m2). The median total operative time was 211 minutes, and the median duration of intracorporeal vaginal cuff suturing was 32 minutes (range, 22 to 47 minutes). The median duration of pelvic lymph node dissection was 31 minutes on one side and 27 minutes on the other side. Patients' postoperative courses were uneventful. The median postoperative hospital stay was 4 days. No postoperative complications occurred. Conclusion When used to treat benign gynecologic tumors and early stage gynecologic cancers, the single-site da Vinci robotic surgery is feasible, safe, and produces favorable surgical outcomes.

    With the introduction of the da Vinci robotic surgical system (Intuitive Surgical, Mountain View, CA) into minimally invasive cardiac surgery, the outlook of performing coronary artery bypass operations "closed chest" became a reality. Between May 1999 and July 2000 this wrist-enhanced instrumentation was used in 143 patients (107 men, 36 women, median age 63 10.3 y). Thirteen patients suffering from coronary artery disease (CAD) were treated as totally endoscopic coronary artery bypass (TECAB), 79 patients underwent a minimally invasive direct coronary artery bypass procedure, and 35 patients were treated using the robotic-enhanced Dresden Technique. Preoperative survival was 100%. All patients in the TECAB group were operated upon via a three- or four-point stab incision using the da Vinci robot for internal mammary artery takedown and for performance of anastomoses. These new robotic-enhanced surgical techniques promote an optimistic way of thinking about the further development of these procedures and its application in patients suffering from CAD.

    Adult subjects drew the visual projection of two models. One model was a trapezoid placed in the frontoparallel plane. The other was a tilted rectangle which displayed the same projective shape on a frontoparallel plane as the trapezoid. The drawing conditions were varied in two ways: the model remained available for inspection during the drawing task or it was masked after initial inspection; the subjects drew on paper placed flat on the table or on a vertical glass pane placed in front of the model (ie on a da Vinci window). The results were that (i) the projective shape of the frontoparallel trapezoid was reproduced accurately whereas that of the tilted rectangle was systemically distorted in the direction of its actual physical dimensions; (ii) when subjects drew on paper, the presence or absence of a view of the model made no difference to the amount of distortion; (iii) drawing on a da Vinci window improved accuracy even when the model was hidden. These findings provide information about the relative roles of object-centred knowledge, perceptual abilities, and depiction skills in drawing performance. PMID:8552463

    Summary In Gram negative bacteria, thiol oxidoreductases catalyze the formation of disulfide bonds (DSB) in extracytoplasmic proteins. In this study, we sought to identify DSB-forming proteins required for assembly of macromolecular structures in Legionella pneumophila. Here we describe two DSB forming proteins, one annotated as dsbA1 and the other annotated as a 27-kDa outer membrane protein similar to Com1 of Coxiella burnetii, which we designate as dsbA2. Both proteins are predicted to be periplasmic, and while dsbA1 mutants were readily isolated and without phenotype, dsbA2 mutants were not obtained. To advance studies of DsbA2, a cis-proline residue at position 198 was replaced with threonine that enables formation of stable disulfide-bond complexes with substrate proteins. Expression of DsbA2 P198T-mutant protein from an inducible promoter produced dominant-negative effects on DsbA2 function that resulted in loss of infectivity for amoeba and HeLa cells and loss of Dot/Icm T4SS-mediated contact hemolysis of erythrocytes. Analysis of captured DsbA2 P198T-substrate complexes from L. pneumophila by mass spectrometry identified periplasmic and outer membrane proteins that included components of the Dot/Icm T4SS. More broadly, our studies establish a DSB oxidoreductase function for the Com1 lineage of DsbA2-like proteins which appear to be conserved among those bacteria also expressing T4SS. PMID:21375592

  12. The Evolution of Dopamine Systems in Chordates

    2011-01-01

    Dopamine (DA) neurotransmission in the central nervous system (CNS) is found throughout chordates, and its emergence predates the divergence of chordates. Many of the molecular components of DA systems, such as biosynthetic enzymes, transporters, and receptors, are shared with those of other monoamine systems, suggesting the common origin of these systems. In the mammalian CNS, the DA neurotransmitter systems are diversified and serve for visual and olfactory perception, sensory–motor programming, motivation, memory, emotion, and endocrine regulations. Some of the functions are conserved among different vertebrate groups, while others are not, and this is reflected in the anatomical aspects of DA systems in the forebrain and midbrain. Recent findings concerning a second tyrosine hydroxylase gene (TH2) revealed new populations of DA-synthesizing cells, as evidenced in the periventricular hypothalamic zones of teleost fish. It is likely that the ancestor of vertebrates possessed TH2 DA-synthesizing cells, and the TH2 gene has been lost secondarily in placental mammals. All the vertebrates possess DA cells in the olfactory bulb, retina, and in the diencephalon. Midbrain DA cells are abundant in amniotes while absent in some groups, e.g., teleosts. Studies of protochordate DA cells suggest that the diencephalic DA cells were present before the divergence of the chordate lineage. In contrast, the midbrain cell populations have probably emerged in the vertebrate lineage following the development of the midbrain–hindbrain boundary. The functional flexibility of the DA systems, and the evolvability provided by duplication of the corresponding genes permitted a large diversification of these systems. These features were instrumental in the adaptation of brain functions to the very variable way of life of vertebrates. PMID:21483723

    Purpose In this study, we report our initial experience with robot-assisted laparoscopic partial cystectomy (RLPC) in urachal diseases. Materials and Methods Two men and two women with a mean age of 51.5±9.3 years underwent RLPC between June 2009 and December 2009. In each case, a single surgeon using the da Vinci-S robotic system (Intuitive Surgical, Sunnyvale, CA, USA) used a transperitoneal approach with a 0° robotic camera. After careful observation of the intravesical portion of the mass, the mass was excised by use of monopolar scissors circumferentially. The bladder was closed in two layers with watertight running sutures made with 2-0 Vicryl. Results The mean operative time was 198 minutes (range, 130-260 minutes), the mean console time was 111 minutes (range, 70-150 minutes), and the mean estimated blood loss was 155 ml. The urethral catheter was removed on postoperative day 7 after a normal cystogram, and the surgical drain was removed on postoperative day 2.5 (range, 2-3 days). The mean hospital stay was 6 days (range, 4-7 days). There were no major complications. The pathology report revealed that one patient had a urachal cystadenoma, two patients had a urachal cyst, and one patient had a patent urachus. Conclusions Our initial experience with RLPC for benign urachal disease is that it is a safe and feasible treatment modality. However, more cases are required to confirm the efficacy of RLPC.

    Natural organic matter from the aquatic environment passing a 1 kDa filter has been hypothesized to not contribute appreciably to hydrophobic organic compound (HOC) partitioning; however, to our knowledge this limit has not been verified experimentally for any sorbate/sorbent system. Presently, colloidal organic carbon (COC) < 1 kDa approached 70% of the total COC (<1.5 ?m) mass in primary effluent (PE) from a municipal wastewater treatment plant. Partitioning of HOCs 1,2,4,5-tetrachlorobenzene, pentachlorobenzene, and hexachlorobenzene to COC for both 1.5 ?m and 1 kDa filtrates of PE was investigated using the gas-stripping technique. Contrary to the hypothesis, significant HOC-COC partitioning to the 1 kDa filtrate was observed with organic carbon-normalized partitioning coefficients (logKCOC) of 4.30, 4.36, and 3.74 for 1,2,4,5-TeCB, PeCB, and HCB, respectively. Further, partitioning to COC < 1 kDa dominated the overall partitioning of the three chlorobenzenes in the 1.5 ?m filtrate, and the partitioning behavior did not follow the trend based on hydrophobicity (KOW). The results show that significant partitioning of HOC may occur to OC < 1 kDa and highlights the need for further experiments with other HOCs and COC characterization to better understand and explain the observed partitioning.

    The impairment of protein degradation via the ubiquitin-proteasome system (UPS) is present in sporadic Parkinson's disease (PD), and might play a key role in selective degeneration of vulnerable dopamine (DA) neurons in the substantia nigra pars compacta (SN). Further evidence for a causal role of dysfunctional UPS in familial PD comes from mutations in parkin, which results in a loss of function of an E3-ubiquitin-ligase. In a mouse model, genetic inactivation of an essential component of the 26S proteasome lead to widespread neuronal degeneration including DA midbrain neurons and the formation of alpha-synuclein-positive inclusion bodies, another hallmark of PD. Studies using pharmacological UPS inhibition in vivo had more mixed results, varying from extensive degeneration to no loss of DA SN neurons. However, it is currently unknown whether UPS impairment will affect the neurophysiological functions of DA midbrain neurons. To answer this question, we infused a selective proteasome inhibitor into the ventral midbrain in vivo and recorded single DA midbrain neurons 2 weeks after the proteasome challenge. We found a selective increase in the mean in vivo firing frequencies of identified DA SN neurons in anesthetized mice, while those in the ventral tegmental area (VTA) were unaffected. Our results demonstrate that a single-hit UPS inhibition is sufficient to induce a stable and selective hyperexcitability phenotype in surviving DA SN neurons in vivo. This might imply that UPS dysfunction sensitizes DA SN neurons by enhancing 'stressful pacemaking'. PMID:25059097

    From the Colosseum to the Roman aqueducts, Italy has historically been admired, envied, and imitated for its feats in advanced engineering. Beginning with Leonardo da Vinci?s military tanks and extending through today in such diverse arenas as high-performance automobiles and technical textiles, Italy has remained at the forefront of cutting-edge engineering. And in the world of biomedical engineering, Italy continues the legacy established by da Vinci in 1489 when he began his pioneering investigations of human physiology. So, it is perhaps unsurprising that Milan should be the setting for the 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, which will be held 25?29 August at the Milan Conference Center.

  12. Origin of the DA and non-DA white dwarf stars

    NASA Technical Reports Server (NTRS)

    Shipman, Harry L.

    1989-01-01

    Various proposals for the bifurcation of the white dwarf cooling sequence are reviewed. 'Primordial' theories, in which the basic bifurcation of the white dwarf sequence is rooted in events predating the white dwarf stage of stellar evolution, are discussed, along with the competing 'mixing' theories in which processes occurring during the white dwarf stage are responsible for the existence of DA or non-DA stars. A new proposal is suggested, representing a two-channel scenario. In the DA channel, some process reduces the hydrogen layer mass to the value of less than 10 to the -7th. The non-DA channel is similar to that in the primordial scenario. These considerations suggest that some mechanism operates in both channels to reduce the thickness of the outermost layer of the white dwarf. It is also noted that accretion from the interstellar medium has little to do with whether a particular white dwarf becomes a DA or a non-DA star.

    Robotic surgical system provides many unique advantages which might compensate the limitations of usual laparoscopic surgery. By using robotic surgical system, we performed robot-assisted laparoscopic pancreaticoduodenectomy (PD). A Sixty-two year old female patient with an ampullary mass underwent robot assisted PD due to imcomplete treatment of endoscopic ampullectomy. The removal of specimen and reconstruction were performed through small upper midline skin incision. Robot working time was about 8 hours, and blood loss was about 800 ml without blood transfusion. She returned to an oral diet on postoperative day 3. Grade B pancreatic leak was noted during the postoperative period, but was successfully managed by conservative management alone. We successfully performed da Vinci-assisted laparoscopic PD, and robot surgical system provided three-dimensional stable visualization and wrist-like motion of instrument facilitated complex operative procedures. More experiences are necessary to address real role of robot in far advanced laparoscopic pancreatic surgery. PMID:22148130

    Background: Serological diagnosis, based on antigenic fractions of the parasite can be used for the early diagnosis of human fascioliasis. The current study aimed to evaluate the efficacy of a 27 kDa immunodominant antigen of Fasciola hepatica adult worms, in an indirect enzyme-linked immunosorbent assay (ELISA) system for serological diagnosis of human fascioliasis. Materials and Methods: The immunodiagnosis of human fascioliasis, using a 27 kDa immunodominant antigen, purified from F. hepatica somatic antigens (SAs), was evaluated by Western blotting and ELISA with sera samples of human fascioliasis patients, healthy controls and patients with other parasitic infections. Results: Using western blotting, from 12 sera of fascioliasis patients, 11 sera (91.6%) detected the 27 kDa subunit. None of 30 samples from healthy controls or 32 sera from nonfascioliasis patients reacted with the 27 kDa antigen. Accordingly, sensitivity and specificity of the system was found to be 91.6% and 100%, respectively. The 27 kDa antigen was purified from the SAs and was used in an indirect ELISA system. Of 15 sera of fascioliasis patients, all (100%) were found to be positive by ELISA whereas only 4 cases (6.25%) of nonfascioliasis patients or healthy controls were false-positive by this system. Accordingly, the sensitivity and specificity of the test were 100% and 93.6%, respectively. Conclusion: Findings of this study demonstrated that both Western blotting and the indirect ELISA, based on the 27 kDa subunit of F. hepatica SA, are reliable methods for serodiagnosis of human fascioliasis.

    PanDA (Production and Distributed Analysis) is the workload management system of the ATLAS experiment, used to run managed production and user analysis jobs on the grid. As a late-binding, pilot-based system, the maintenance of a smooth and steady stream of pilot jobs to all grid sites is critical for PanDA operation. The ATLAS Computing Facility (ACF) at BNL, as the ATLAS Tier1 center in the US, operates the pilot submission systems for the US. This is done using the PanDA 'AutoPilot' scheduler component which submits pilot jobs via Condor-G, a grid job scheduling system developed at the University of Wisconsin-Madison. In this paper, we discuss the operation and performance of the Condor-G pilot submission at BNL, with emphasis on the challenges and issues encountered in the real grid production environment. With the close collaboration of Condor and PanDA teams, the scalability and stability of the overall system has been greatly improved over the last year. We review improvements made to Condor-G resulting from this collaboration, including isolation of site-based issues by running a separate Gridmanager for each remote site, introduction of the 'Nonessential' job attribute to allow Condor to optimize its behavior for the specific character of pilot jobs, better understanding and handling of the Gridmonitor process, as well as better scheduling in the PanDA pilot scheduler component. We will also cover the monitoring of the health of the system.

    Essential components of animal behaviour are modulated by dopaminergic (DA) and noradrenergic circuitry. In this study, we reveal at cellular resolution the complete set of projections ('projectome') of every single type of DA and noradrenergio neurons in the central nervous system of zebrafish larvae. The most extensive DA projections are established by posterior tubercular otp-dependent neurons, with individual somata integrating the ascending DA system, the descending diencephalospinal, as well as the endohypothalamic circuitry. These findings suggest a major role in the modulation of physiology and behaviour for otp-dependent DA neurons, which correlate with the mammalian A11 group. We further identified an endogenous subpallial DA system that not only provides most of the local DA projections, but also connects to the ventral diencephalon. The catecholaminergic projectome map provides a framework to understand the evolution and function of these neuromodulatory systems. PMID:21266970

    Abstract The introduction of robotic surgical systems and their integration into minimally invasive procedures have changed the landscape of laparoscopic surgery dramatically. Intuitive Surgical's da Vinci Surgical System was first approved by the Food and Drug Administration for cardiothoracic procedures in the late 1990s. This trend quickly spread through other surgical specialties, with urologists as one of the frontrunners in adoption. Subsequently, pediatric urologists have adopted robot-assisted procedures in selected centers, performing procedures such as pyeloplasty for ureteropelvic junction obstruction, partial and complete nephrectomy, and both intravesical and extravesical ureteral reimplantation. In this article, we will discuss technical considerations related to patient positioning and port placement in pediatric robot-assisted surgery. PMID:24548088

    Today mini invasive surgery has the chance to be enhanced with sophisticated informative systems (Computer Assisted Surgery, CAS) like robotics, tele-mentoring and tele-presence. ZEUS and da Vinci, present in more than 120 Centres in the world, have been used in many fields of surgery and have been tested in some general surgical procedures. Since the end of 2003, we have performed 70 experimental procedures and 24 operations of general surgery with ZEUS robotic system, after having properly trained 3 surgeons and the operating room staff. Apart from the robot set-up, the mean operative time of the robotic operations was similar to the laparoscopic ones; no complications due to robotic technique occurred. The Authors report benefits and disadvantages related to robots' utilization, problems still to be solved and the possibility to make use of them with tele-surgery, training and virtual surgery.

    Resection of retroperitoneal tumors is usually perfomed using the anterior retroperitoneal approach. Our report presents an innovative method utilizing a robotic surgical system. A 50-yr-old male patient visited our hospital due to a known paravertebral mass. Magnetic resonance imaging showed a well-encapsulated mass slightly abutting the abdominal aorta and left psoas muscle at the L4-L5 level. The tumor seemed to be originated from the prevertebral sympathetic plexus or lumbosacral trunk and contained traversing vessels around the tumor capsule. A full-time robotic transperitoneal tumor resection was performed. Three trocars were used for the robotic camera and working arms. The da Vinci Surgical System® provided delicate dissection in the small space and the tumor was completely removed without damage to the surrounding organs and great vessels. This case demonstrates the feasibility of robotic resection in retroperitoneal space. Robotic surgery offered less invasiveness in contrast to conventional open surgery. PMID:21218046

    We present a detailed model atmosphere analysis of the strength and geometry of the magnetic field in cool, hydrogen-line (DA) white dwarfs using offset dipole models. We show in particular that most stars in our sample can only be accounted for if they are unresolved double white dwarf systems, one of which even consists of two magnetic DA stars. Our results also suggest that the magnetic field in these cool white dwarfs cannot have a fossil origin, and must be somehow generated by some mechanism that remains unexplained at this stage.

  1. Robotic-Assisted Minimally Invasive Surgery for Gynecologic and Urologic Oncology

    PubMed Central

    2010-01-01

    Executive Summary Objective An application was received to review the evidence on the ‘The Da Vinci Surgical System’ for the treatment of gynecologic malignancies (e.g. endometrial and cervical cancers). Limitations to the current standard of care include the lack of trained physicians on minimally invasive surgery and limited access to minimally invasive surgery for patients. The potential benefits of ‘The Da Vinci Surgical System’ include improved technical manipulation and physician uptake leading to increased surgeries, and treatment and management of these cancers. The demand for robotic surgery for the treatment and management of prostate cancer has been increasing due to its alleged benefits of recovery of erectile function and urinary continence, two important factors of men’s health. The potential technical benefits of robotic surgery leading to improved patient functional outcomes are surgical precision and vision. Clinical Need Uterine and cervical cancers represent 5.4% (4,400 of 81,700) and 1.6% (1,300 of 81,700), respectively, of incident cases of cancer among female cancers in Canada. Uterine cancer, otherwise referred to as endometrial cancer is cancer of the lining of the uterus. The most common treatment option for endometrial cancer is removing the cancer through surgery. A surgical option is the removal of the uterus and cervix through a small incision in the abdomen using a laparoscope which is referred to as total laparoscopic hysterectomy. Risk factors that increase the risk of endometrial cancer include taking estrogen replacement therapy after menopause, being obese, early age at menarche, late age at menopause, being nulliparous, having had high-dose radiation to the pelvis, and use of tamoxifen. Cervical cancer occurs at the lower narrow end of the uterus. There are more treatment options for cervical cancer compared to endometrial cancer, however total laparoscopic hysterectomy is also a treatment option. Risk factors that increase the risk for cervical cancer are multiple sexual partners, early sexual activity, infection with the human papillomavirus, and cigarette smoking, whereas barrier-type of contraception as a risk factor decreases the risk of cervical cancer. Prostate cancer is ranked first in men in Canada in terms of the number of new cases among all male cancers (25,500 of 89,300 or 28.6%). The impact on men who develop prostate cancer is substantial given the potential for erectile dysfunction and urinary incontinence. Prostate cancer arises within the prostate gland, which resides in the male reproductive system and near the bladder. Radical retropubic prostatectomy is the gold standard treatment for localized prostate cancer. Prostate cancer affects men above 60 years of age. Other risk factors include a family history of prostate cancer, being of African descent, being obese, consuming a diet high in fat, physical inactivity, and working with cadium. The Da Vinci Surgical System The Da Vinci Surgical System is a robotic device. There are four main components to the system: 1) the surgeon’s console, where the surgeon sits and views a magnified three-dimensional image of the surgical field; 2) patient side-cart, which sits beside the patient and consists of three instrument arms and one endoscope arm; 3) detachable instruments (endowrist instruments and intuitive masters), which simulate fine motor human movements. The hand movements of the surgeon’s hands at the surgeon’s console are translated into smaller ones by the robotic device and are acted out by the attached instruments; 4) three-dimensional vision system: the camera unit or endoscope arm. The main advantages of use of the robotic device are: 1) the precision of the instrument and improved dexterity due to the use of “wristed” instruments; 2) three-dimensional imaging, with improved ability to locate blood vessels, nerves and tissues; 3) the surgeon’s console, which reduces fatigue accompanied with conventional laparoscopy surgery and allows for

    The PAN-DA data acquisition software system encompasses support for a variety of front end processors including the Struck General Purpose Master (GPM), the Fermilab Smart Crate Controller (FSCC), and the Motorola MVME133-A VME single board computer. PAN-DA provides support for the remote control of these processors through its Remote Procedure eXecution (RPX) software. This software runs over serial lines, and in some PAN-DA environments, over the Ethernet and TCP/IP as well. Experiments E791 and E771 have successfully used RPX software in both FSCC software development and data collection during the 1990--1991 fixed target run at Fermilab. RPX software has facilitated development and testing of the Fermilab Silicon Strip Detector readout system, for which the FSCC is an integral component. RPX based control and monitoring of the GPM and the MVME133-A are essential parts of the PAN-DA data acquisition system used by E687 and E773 during the 1990--1991 run. 6 refs., 2 figs.

    Mango fruit has become increasingly popular in recent years. We report on 2 patients who developed anaphylactic reactions after the ingestion of fresh mango. Allergy to mango was confirmed by a positive skin prick test result and positive cellular allergen stimulation test results. Neither of the patients had detectable mango-specific immunoglobulin (Ig) E levels. Results were validated by sodium dodecyl sulfate polyacrylamide gel electrophoresis immunoblotting and analyzed using Quantiscan.We identified 2 major allergens with a molecular weight of 27 kDa in both patients, in addition to a 15 kDa allergen in 1 patient and a 32 kDa allergen in the other. Currently available IgE systems seem to be lacking these mango allergens and as such are probably unsuitable for diagnosing type 1 sensitization to mango. Skin prick testing with fresh mango fruit therefore seems to be a much more reliable test method for clinical practice. PMID:19123442

    2007-01-01

    The foundation of surgical robotics is in the development of the robotic arm. This is a thorough review of the literature on the nature and development of this device with emphasis on surgical applications. We have reviewed the published literature and classified robotic arms by their application: show, industrial application, medical application, etc. There is a definite trend in the manufacture of robotic arms toward more dextrous devices, more degrees-of-freedom, and capabilities beyond the human arm. da Vinci designed the first sophisticated robotic arm in 1495 with four degrees-of-freedom and an analog on-board controller supplying power and programmability. von Kemplen's chess-playing automaton left arm was quite sophisticated. Unimate introduced the first industrial robotic arm in 1961, it has subsequently evolved into the PUMA arm. In 1963 the Rancho arm was designed; Minsky's Tentacle arm appeared in 1968, Scheinman's Stanford arm in 1969, and MIT's Silver arm in 1974. Aird became the first cyborg human with a robotic arm in 1993. In 2000 Miguel Nicolalis redefined possible man-machine capacity in his work on cerebral implantation in owl-monkeys directly interfacing with robotic arms both locally and at a distance. The robotic arm is the end-effector of robotic systems and currently is the hallmark feature of the da Vinci Surgical System making its entrance into surgical application. But, despite the potential advantages of this computer-controlled master-slave system, robotic arms have definite limitations. Ongoing work in robotics has many potential solutions to the drawbacks of current robotic surgical systems. PMID:25484945

    Purpose The da Vinci® robot system has been used to perform complex reconstructive procedures in a minimally invasive fashion. Robot-assisted laparoscopic radical prostatectomy has recently established as one of the standard cares. Based on experience with the robotic prostatectomy, its use is naturally expanding into other urologic surgeries. We examine our practical pattern and application of da Vinci® robot system in urologic field. Patients and Methods Robotic urologic surgery has been performed during a period from July 2005 to August 2008 in a total of 708 cases. Surgery was performed by 7 operators. In our series, radical prostatectomy was performed in 623 cases, partial nephrectomy in 43 cases, radical cystectomy in 11 cases, nephroureterectomy in 18 cases and other surgeries in 15 cases. Results In the first year, robotic urologic surgery was performed in 43 cases. However, in the second year, it was performed in 164 cases, and it was performed in 407 cases in the third year. In the first year, only prostatectomy was performed. In the second year, partial nephrectomy (2 cases), nephroureterectomy (3 cases) and cystectomy (1 case) were performed. In the third year, other urologic surgeries than prostatectomy were performed in 64 cases. The first robotic surgery was performed with long operative time. For instance, the operative time of prostatectomy, partial nephrectomy, cystectomy and nephroureterectomy was 418, 222, 340 and 320 minutes, respectively. Overall, the mean operative time of prostatectomy, partial nephrectomy, cystectomy and nephrourectectomy was 179, 173, 309, and 206 minutes, respectively. Conclusion Based on our experience at a single-institution, robot system can be used both safely and efficiently in many areas of urologic surgeries including prostatectomy. Once this system is familiar to surgeons, it will be used in a wide range of urologic surgery. PMID:19108011

    2012-09-01

    The mesolimbic dopaminergic system (ML-DA) allows adapted interactions with the environment and is therefore of critical significance for the individual's survival. The ML-DA system is implicated in reward and emotional functions, and it is perturbed in schizophrenia, addiction, and depression. The ML-DA reward system is not only recruited during wakeful behaviors, it is also active during sleep. Here, we introduce the Reward Activation Model (RAM) for sleep and dreaming, according to which activation of the ML-DA reward system during sleep contributes to memory processes, to the regulation of rapid-eye movement (REM) sleep, and to the generation and motivational content of dreams. In particular, the engagement of ML-DA and associated limbic structures prioritizes information with high emotional or motivational relevance for (re)processing during sleep and dreaming. The RAM provides testable predictions and has clinical implications for our understanding of the pathogenesis of major depression and addiction. PMID:22669078

    Transoral robotic-assisted lingual tonsillectomy seems to confirm good tolerability with efficient results in both adult and pediatric populations, and the complication rate is usually dependent on the specific procedure and not related to the use of the robotic techniques. In these clinical reports, a 44-year-old woman (patient 1) and a 49-year-old woman (patient 2) were referred to our clinic with long-term complaints of dysphagia, snoring, and globus sensation. The patients were diagnosed with a lingual tonsillar hypertrophy, and lingual tonsillectomy was performed through transoral robotic surgery using the robotic da Vinci surgical system. After 2 months of uneventful follow-up, the patients returned with dysphagia, and examination of the patients revealed a cicatricial synechia surrounding the oropharynx. We report 2 cases of oropharyngeal stenosis that occurred during the late postoperative period after transoral assisted lingual tonsillectomy with epiglottoplasty. Possible risk factors and treatment alternatives were also discussed. PMID:25901674

    A 49-year-old woman was referred to our department for increased schwannoma of the right neck and mediastinum. We chose a robot-assisted endoscopic approach to minimize the operative trauma. After exposure of the thyroid through the right axilla, the neck tumor was resected using the da Vinci Surgical System. A mini-thoracotomy was then made in the left third intercostal space through the axillary incision, robotic instruments were introduced across the thoracic cavity, and the tumor was excised circumferentially using the robot. Histopathological examination of both specimens revealed schwannomas. This procedure has benefited the patient with good cosmetic results and allowed her to rapidly resume her daily activities.

    Robotically assisted totally endoscopic coronary artery bypass surgery has emerged as a feasible and efficient alternative to conventional full sternotomy coronary artery bypass graft surgery in selected patients. This minimally invasive approach using the daVinci robotic system allows fine intrathoracic maneuvers and excellent view of the coronary arteries. Both on-pump and off-pump operations can be performed to treat single and multivessel disease. Hybrid approaches have the potential of offering complete revascularization with the “best of both worlds” from surgery (internal mammary artery anastomosis in less invasive fashion) and percutaneous coronary intervention (least invasive approach). In this article we review the indications, techniques, short and long term results, as well as current developments in totally endoscopic robotic coronary artery bypass operations. PMID:24251021

    Pre-coccygeal ganglioneuroma is a rare clinical entity that presents incidentally or with non-specific symptoms. We present a case of a 25 year old housewife who was incidentally diagnosed with pre-coccygeal ganglioneuroma while getting investigated for primary infertility. The patient had no specific complaints except for irregular menstruation which had started 8 months back. Magnetic resonance imaging (MRI) was suggestive of a presacral and pre-coccygeal lesion. Resection of the tumor was done through the anterior approach using the da Vinci Si robotic system. Two robotic arms and one assistant port were used to completely excise the tumor. Robotic excision of such a tumor mass located at a relatively inaccessible area allows enhanced precision and 3-dimentional (3D) view avoiding damage to important surrounding structures.

    As minimally invasive surgery has become common in head and neck surgery, the role of robotic surgery has expanded from thyroid surgery and transoral robotic surgery (TORS) of the oropharynx and supraglottic to other areas. Surgeons have advanced the limits of TORS, adapting lasers to the Da Vinci robot for glottic cancer, and combining existing techniques for transoral supraglottic laryngectomy and hypopharyngectomy to perform transoral total laryngectomy. Skull base approaches have been reported with some success in case reports and cadaver models, but the current instrument size and configuration limit the applicability of the current robotic system. Surgeons have reported reconstruction of the head and neck via local and free flaps. Using the previously reported approaches for thyroidectomy via modified facelift incision, neck dissection has also been reported. Future applications of robotic surgery in otolaryngology may be additionally expanded, as several new robotic technologies are under development for endolaryngeal work and neurotology. PMID:24069577

  4. Enhancing nurse mobility in Europe: a case for language skills.

    The recognition of professional qualifications in all European Union (EU) member states for nurses is covered by both sectoral and general systems directives, yet in reality, few nurses take up their rights as European citizens to live and work in another EU country. One of the main reasons for this is a lack of linguistic skills. This article argues that the nursing profession should be taking a more active role in enabling nurses to move freely around Europe by encouraging language acquisition. It is argued that there are political, social, economic, professional and individual reasons why this should be so. The author gives a brief account of a pilot project which is currently under way to help improve (albeit in a small way) this situation. The project, which has been granted financial support of 100,000 ECU from the European Commission's new training programme, Leonardo da Vinci, will create a multimedia language pack in four languages aimed specifically at nurses.

    Robotics has been commonly employed in numerous industrial fields for several decades. However, the application of this technology to surgery is a recent innovation. It provides new possibilities for facilitating specific surgical tasks, especially in the field of laparoscopy. We report a case of laparoscopic radical prostatectomy completed with the help of a remotely controlled da Vinci robot. This system offered a user friendly surgical platform and enhanced surgical dexterity. Operating time was 420 minutes and the hospital stay was 4 days. The bladder catheter was removed after 3 days. One week later, the patient was fully continent. Pathologic examination showed a pT3a tumor, with negative margins. Robotically assisted laparoscopic radical prostatectomy is feasible. Further developments in this field of technology may have new applications in laparoscopic telesurgery. PMID:11064890

    Written five centuries after the first studies of Leonardo da Vinci and half a century after A.N. Kolmogorov's first attempt to predict the properties of flow, this textbook presents a modern account of turbulence, one of the greatest challenges in physics. "Fully developed turbulence" is ubiquitous in both cosmic and natural environments, in engineering applications and in everyday life. Elementary presentations of dynamical systems ideas, probabilistic methods (including the theory of large deviations) and fractal geometry make this a self-contained textbook. This is the first book on turbulence to use modern ideas from chaos and symmetry breaking. The book will appeal to first-year graduate students in mathematics, physics, astrophysics, geosciences and engineering, as well as professional scientists and engineers.

    The occurrence and characteristics of vortices in flows are explored comprehensively, including historical observations and representations dated several millenia BC. Attention is given to the development of the scientific concept of vortices, and the basic concepts and kinematics of vortices are reviewed, as are the properties of simple vortices. The genesis and behavior of vorticity is traced through separation, instability, and turbulence. Fluid flow in a rotating system is explored, as are stratification in the ocean and atmosphere, circulations in the atmosphere, ocean, and earth, and the features of single vortices in the atmosphere and oceans. Hurrican formations are investigated, together with extraterrestrial vortices in planetary atmospheres, stars, and galaxies. A plethora of photographs and illustrations is presented, including drawings by Leonardo da Vinci.

    2013-01-01

    Background and Objectives: Giant paraesophageal hernia accounts for 5% of all hiatal hernias, and it is commonly seen in elderly patients with comorbidities. Some series report complication rates up to 28%, recurrence rates between 10% and 25%, and a mortality rate close to 2%. Recently, the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) has shown equivocal benefits when used for elective surgeries, whereas for complex procedures, the benefits appear to be clearer. The purpose of this study is to present our preliminary experience in robotic giant paraesophageal hernia repair. Methods: We retrospectively collected data from patients who had a diagnosis of giant paraesophageal hernia and underwent a paraesophageal hernia repair with the da Vinci Surgical System. Results: Nineteen patients (12 women [63.1%]) underwent surgery for giant paraesophageal hernia at our center. The mean age was 70.4 ± 13.9 years (range, 40–97 years). The mean American Society of Anesthesiologists score was 2.15. The mean surgical time and hospital length of stay were 184.5 ± 96.2 minutes (range, 96–395 minutes) and 4.3 days (range, 2–22 days), respectively. Nissen fundoplications were performed in 3 cases (15.7%), and 16 patients (84.2%) had mesh placed. Six patients (31.5%) presented with gastric volvulus, and 2 patients had other herniated viscera (colon and duodenum). There were 2 surgery-related complications (10.5%) (1 dysphagia that required dilatation and 1 pleural injury) and 1 conversion to open repair (partial gastric resection). No recurrences or deaths were observed in this series. Conclusion: In our experience robotic giant paraesophageal hernia repair is not different from the laparoscopic approach in terms of complications and mortality rate, but it may be associated with lower recurrence rates. However, larger series with longer follow-up are necessary to further substantiate our results. PMID:24398199

    2012-01-01

    Background Currently, data are not available concerning a safe insufflation pressure that provides a proper view of the surgical field without adverse metabolic and hemodynamic changes in humans undergoing the robot-assisted thyroidectomy bilateral axillo-breast approach (BABA) using the da Vinci robotic surgical system. The purpose of this study was to determine the optimal carbon dioxide (CO2) insufflation pressure in patients with various benign and malignant thyroid diseases when using the da Vinci robotic surgical system. Methods A total of 32 patients underwent thyroid surgery at 6 (n = 15), 9 (n = 15), and 12 (n = 2) mmHg. The partial pressure of carbon dioxide (PaCO2), pH, cardiac output, heart rate, and mean arterial pressure were measured at baseline, 30 min and 1, 1.5, and 2 hours after CO2 insufflation, and 30 min after desufflation. Results CO2 insufflation of 12 mmHg caused severe facial subcutaneous emphysema, hypercarbia, and acidosis during robot-assisted thyroidectomy with BABA. The study was stopped before completion for the patients’ safety in accordance with the study protocol. Applying 6- or 9- mmHg of CO2 insufflation pressure caused increases in PaCO2 and decreases in arterial pH. However, vital signs were stable and pH and PaCO2 were within the physiologic range during the surgery in the 6- and 9-mmHg groups. Conclusions We propose that a CO2 insufflation pressure under 10 mmHg in robot-assisted thyroidectomy with BABA is the optimal insufflation pressure for patient safety. PMID:23017080

    2012 DA14 made an extremely close approach within 0.00023 AU (0.09 lunar distances) on February 15, 2013. This was the closest encounter known in advance by a near-Earth asteroid with an absolute magnitude brighter than 25. We took advantage of this opportunity to image 2012 DA14 at Goldstone on February 16, 18, and 19 as the asteroid was receding from Earth. The imaging started at 00:46 UTC, slightly more than five hours after the closest approach, when the asteroid was at a distance of 0.00088 AU (0.34 lunar distances). The echoes were extraordinarily strong and we obtained some of the highest signal-to-noise ratios for any near-Earth asteroid ever observed at Goldstone. The images achieved resolutions as fine as 3.75 m x 0.00625 Hz that spatially resolve 2012 DA14 into a few dozen pixels; however, due to the diminutive dimensions of the asteroid, even this extremely high resolution is insufficient to show detailed surface features. The images indicate that 2012 DA14 is an asymmetric, angular, and elongated object with major axes of roughly 40 x 20 meters. The sequence of images obtained on February 16 spans 7.8 hours, during which the orientation of the asteroid appeared to complete close to one full rotation, suggesting that the rotation period is somewhat longer than ~8 hours. Radar speckle tracking with the Very Large Array and elements of the Very Long Baseline array show that 2012 DA14 has a relatively low obliquity and constrain the amplitude of any non-principal axis wobble after the flyby to be < 30 degrees. 2012 DA14 is among the smallest near-Earth asteroids ever spatially resolved by radar and it highlights the substantial scientific potential of the new chirp imaging system at Goldstone.

    Import of proteins into mitochondria involves the cooperation of protein translocation systems in the outer and inner membranes. We have identified a 45-kDa protein at the protein import site of the yeast mitochondrial inner membrane. This 45-kDa protein could be crosslinked to a partly translocated precursor, which cannot be imported across the inner membrane when the matrix is depleted of ATP. In addition, an antibody against this protein strongly inhibited protein import into right-side-out inner-membrane vesicles. The 45-kDa protein accounts for only 0.1% of mitochondrial protein and appears peripherally attached to the outer face of the inner membrane. The properties of this protein suggest that it is a component of the protein import system of the mitochondrial inner membrane. PMID:1465421

    A hybrid machine learning methodology and system for classification that combines classical random forest (RF) methodology with discriminant analysis (DA) techniques to provide enhanced classification capability. A DA technique which uses feature measurements of an object to predict its class membership, such as linear discriminant analysis (LDA) or Andersen-Bahadur linear discriminant technique (AB), is used to split the data at each node in each of its classification trees to train and grow the trees and the forest. When training is finished, a set of n DA-based decision trees of a discriminant forest is produced for use in predicting the classification of new samples of unknown class.

    Prostate tumours are among the most frequently diagnosed solid tumours in males (a total of 192,280 new cases in the USA in 2009); since the approval of the PSA test by the Food and Drug Administration in 1986, incidence has risen significantly, particularly in the '90s; furthermore the spread of the PSA test has led to an increased frequency of cancer diagnosis at the localised stage. The standard treatment for tumour of the prostate is retropubic radical prostatectomy (RRP) which however is not morbidity-free, e.g. intraoperative bleeding, urinary incontinence and erectile dysfunction. This is why the interest of the scientific community has turned increasingly to mini-invasive surgical procedures able to achieve the same oncological results as the open procedure, but which also reduce the impact of the treatment on these patients' quality of life. The first step in this direction was laparoscopic prostatectomy described by Schuessler in 1992 and standardised by Gaston in 1997. However, the technical difficulty inherent in this procedure has limited its more widespread use. In May 2000 Binder and Kramer published a report on the first robot-assisted prostatectomy (RARP) using the Da Vinci system (da Vinci TM, Intuitive Surgical, Sunnyvale, CA, USA). From the original experience, RARP, which exploits the advantages of an enlarged, three-dimensional view and the ability of the instruments to move with 7 degrees of freedom, the technique has spread enormously all over the world. At the time of writing, in the USA, RARP is the most common therapeutic option for the treatment of prostate tumour at localised stage. In the present study we describe the RARP technique proposed by dr. Vipul Patel, head of the Global Robotic Institute (Orlando Fl). PMID:20940698

  14. PanDA: A New Paradigm for Distributed Computing in HEP Through the Lens of ATLAS and other Experiments

    2014-01-01

    Experiments at the Large Hadron Collider (LHC) face unprecedented computing challenges. Heterogeneous resources are distributed worldwide, thousands of physicists analyzing the data need remote access to hundreds of computing sites, the volume of processed data is beyond the exabyte scale, and data processing requires more than a billion hours of computing usage per year. The PanDA (Production and Distributed Analysis) system was developed to meet the scale and complexity of LHC distributed computing for the ATLAS experiment. In the process, the old batch job paradigm of computing in HEP was discarded in favor of a far more flexible and scalable model. The success of PanDA in ATLAS is leading to widespread adoption and testing by other experiments. PanDA is the first exascale workload management system in HEP, already operating at a million computing jobs per day, and processing over an exabyte of data in 2013. We will describe the design and implementation of PanDA, present data on the performance of PanDA a...

    Delvotest SP NT DA is designed to test milk for the presence of antibacterial substances, such as antibiotics. The test is made of an agar gel containing bacterial spores and a color indicator. The milk sample is added onto the agar gel, and the test is incubated at 64 degrees C. The principle of the test is based on the diffusion of possible inhibitory substances that may be present in the milk sample into agar. This reduces growth and acid production by the test organism, and delays or prevents the agar from changing color from purple to yellow. The Delvotest Accelerator is an automated system in which the plates containing the milk to be analyzed are placed for incubation. The Accelerator automatically detects the end of the incubation and reads the results. A sample containing antibiotic will be noted as "positive." A sample without antibiotics or with antibiotics at concentrations below detection level will be noted as "negative." The present report includes all technical details about the Delvotest SP NT DA, and the results of the validation study. The validation study demonstrates that the Delvotest SP NT DA conforms to the product performance claims and confirms the robustness of the test. The Delvotest SP NT DA is, therefore, granted Performance Tested Method certification. PMID:22468368

    É amplamente reconhecido que as pessoas em geral têm grande fascínio e interesse pela Astronomia. Por outro lado, o conteúdo dessa área incluído no ensino formal está longe de ser abrangente e suficiente para suprir a demanda. Esse interesse permite aperfeiçoar a divulgação e o ensino não formal de Astronomia através da mídia aliando a adequação do conteúdo à expectativa das pessoas. A reforma do Currículo Básico da Escola Pública da maioria dos Estados brasileiros tem introduzido Astronomia desde a pré-escola até o Ensino Médio. Num estudo realizado com 1180 alunos do Ensino Médio de seis escolas estaduais, revelou-se através da aplicação de um formulário contendo questões que abordavam conhecimentos básicos em Astronomia, como foram adquiridos tais conhecimentos e à infra-estrutura da escola. Para 66,1% dos entrevistados o professor já fez alguma apresentação a respeito de Astronomia. O presente estudo revelou também que 54,4% dos alunos entrevistados adquiriram seus conhecimentos astronômicos na escola, 18,4% através da televisão e 27,1% afirmaram que seus conhecimentos foram obtidos através de outros tipos de mídia (internet, livros didáticos, filmes e revistas). Embora o estudo revele claramente que há certo equilíbrio no meio em que os alunos obtiveram seus conhecimentos astronômicos, a mídia busca não somente sua difusão, mas a disponibilização desse conhecimento de maneira correta, que às vezes, não é atingido, apresentando conceitos sem fundamentação e incorretos. Por outro lado, no dia-a-dia escolar, é comum encontrar professores que vêm para as aulas com concepções prévias, que podem diferir substancialmente das idéias a serem ensinadas, dificultando o aprendizado de futuros conceitos científicos. Uma avaliação criteriosa, avaliando as dificuldades dos professores em determinar o sentido correto dos conceitos e observando a metodologia que utilizam no ensino, poderá proporcionar uma melhor compreensão sobre as concepções alternativas, presentes no ensino de Astronomia.

    Deschampsia antarctica is an Antarctic hairgrass that grows on the west coast of the Antarctic peninsula. In this report, we have identified and characterized a transcription factor, D. antarctica C-repeat binding factor 7 (DaCBF7), that is a member of the monocot group V CBF homologs. The protein contains a single AP2 domain, a putative nuclear localization signal, and the typical CBF signature. DaCBF7, like other monocot group V homologs, contains a distinct polypeptide stretch composed of 43 amino acids in front of the AP2 motif. DaCBF7 was predominantly localized to nuclei and interacted with the C-repeat/dehydration responsive element (CRT/DRE) core sequence (ACCGAC) in vitro. DaCBF7 was induced by abiotic stresses, including drought, cold, and salinity. To investigate its possible cellular role in cold tolerance, a transgenic rice system was employed. DaCBF7-overexpressing transgenic rice plants (Ubi:DaCBF7) exhibited markedly increased tolerance to cold stress compared to wild-type plants without growth defects; however, overexpression of DaCBF7 exerted little effect on tolerance to drought or salt stress. Transcriptome analysis of a Ubi:DaCBF7 transgenic line revealed 13 genes that were up-regulated in DaCBF7-overexpressing plants compared to wild-type plants in the absence of cold stress and in short- or long-term cold stress. Five of these genes, dehydrin, remorin, Os03g63870, Os11g34790, and Os10g22630, contained putative CRT/DRE or low-temperature responsive elements in their promoter regions. These results suggest that overexpression of DaCBF7 directly and indirectly induces diverse genes in transgenic rice plants and confers enhanced tolerance to cold stress. PMID:26025521

    2014-01-01

    The ventral tegmental area (VTA) is a heterogeneous brain structure that serves a central role in motivation and reward processing. Abnormalities in the function of VTA dopamine (DA) neurons and the targets they influence are implicated in several prominent neuropsychiatric disorders including addiction and depression. Recent studies suggest that the midbrain DA system is composed of anatomically and functionally heterogeneous DA subpopulations with different axonal projections. These findings may explain a number of previously confusing observations that suggested a role for DA in processing both rewarding as well as aversive events. Here we will focus on recent advances in understanding the neural circuits mediating reward and aversion in the VTA and how stress as well as drugs of abuse, in particular cocaine, alter circuit function within a heterogeneous midbrain DA system.

    Data Assimilation techniques are essential elements in state-of-the-art development of models and their optimization with data in the field of groundwater, surface water and soil systems. They are essential tools in calibration of complex modelling systems and improvement of model forecasts. The OpenDA is a new and generic open source data assimilation environment for application to a choice of physical process models, applied to case dependent domains. OpenDA was introduced recently when the developers of Costa, an open-source TU Delft project [http://www.costapse.org; Van Velzen and Verlaan; 2007] and those of the DATools from the former WL|Delft Hydraulics [El Serafy et al 2007; Weerts et al. 2009] decided to join forces. OpenDA makes use of a set of interfaces that describe the interaction between models, observations and data assimilation algorithms. It focuses on flexible applications in portable systems for modelling geophysical processes. It provides a generic interfacing protocol that allows combination of the implemented data assimilation techniques with, in principle, any time-stepping model duscribing a process(atmospheric processes, 3D circulation, 2D water level, sea surface temperature, soil systems, groundwater etc.). Presently, OpenDA features filtering techniques and calibration techniques. The presentation will give an overview of the OpenDA and the results of some of its practical applications.

    Oleoylethanolamide (OEA) is an agonist of the peroxisome proliferator-activated receptor ? (PPAR?) and has been described to exhibit neuroprotective properties when administered locally in animal models of several neurological disorder models, including stroke and Parkinson's disease. However, there is little information regarding the effectiveness of systemic administration of OEA on Parkinson's disease. In the present study, OEA-mediated neuroprotection has been tested on in vivo and in vitro models of 6-hydroxydopamine (6-OH-DA)-induced degeneration. The in vivo model was based on the intrastriatal infusion of the neurotoxin 6-OH-DA, which generates Parkinsonian symptoms. Rats were treated 2 h before and after the 6-OH-DA treatment with systemic OEA (0.5, 1, and 5 mg/kg). The Parkinsonian symptoms were evaluated at 1 and 4 wk after the development of lesions. The functional status of the nigrostriatal system was studied through tyrosine-hydroxylase (TH) and hemeoxygenase-1 (HO-1, oxidation marker) immunostaining as well as by monitoring the synaptophysin content. In vitro cell cultures were also treated with OEA and 6-OH-DA. As expected, our results revealed 6-OH-DA induced neurotoxicity and behavioural deficits; however, these alterations were less severe in the animals treated with the highest dose of OEA (5 mg/kg). 6-OH-DA administration significantly reduced the striatal TH-immunoreactivity (ir) density, synaptophysin expression, and the number of nigral TH-ir neurons. Moreover, 6-OH-DA enhanced striatal HO-1 content, which was blocked by OEA (5 mg/kg). In vitro, 0.5 and 1 ?M of OEA exerted significant neuroprotection on cultured nigral neurons. These effects were abolished after blocking PPAR? with the selective antagonist GW6471. In conclusion, systemic OEA protects the nigrostriatal circuit from 6-OH-DA-induced neurotoxicity through a PPAR?-dependent mechanism. PMID:24169105

  4. Explaining caesarean section in Salvador da Bahia, Brazil.

    PubMed

    McCallum, Cecilia

    2005-03-01

    In Salvador da Bahia the caesarean section rate is excessive, as it is in Brazil as a whole. It is the standard form of delivery in private hospitals, though vaginal delivery still predominates in the public sector. This paper investigates the social context of these styles of childbirth, arguing that the connections between both sectors sustain this situation. Exploring the factors leading to the preference in private and insurance-funded maternity wards, it examines critically two diverging positions on the cause of the rate: that women's cultural preferences for abdominal birth lie behind it; or that obstetricians' self-interest is to blame. The paper critiques the theory of culture behind the first stance and questions the theoretical weight placed on individual action in the second. It argues that no particular social group is the principal cause of the excessive use of caesarean section to deliver babies. Rather, a host of factors converge in sustaining this practice. Finally, the paper stresses that the system as a whole, not any particular group, must be changed if the rate is to be lowered significantly. For this, political will is required. PMID:15787776

    Requirements of future space systems, including large space systems, that operate beyond the space shuttle are discussed. Typical functions required of propulsion systems in this operational regime include payload placement, retrieval, observation, servicing, space debris control and support to large space systems. These functional requirements are discussed in conjunction with two classes of propulsion systems: (1) primary or orbit transfer vehicle (OTV) and (2) secondary or systems that generally operate within or relatively near an operational base orbit. Three propulsion system types are described in relation to these requirements: cryogenic OTV, teleoperator maneuvering system and a solar electric OTV.

    Several clinical reports have suggested that there is a hyperactivation of the dopaminergic system in people with autism. Using rats exposed prenatally to valproic acid (VPA) as an animal model of autism, we measured dopamine (DA) levels in samples collected from the frontal cortex (FC) using in vivo microdialysis and HPLC. The basal DA level in FC was significantly higher

    The ability of affinity purified anti-52 kDa Ro/SSA antibody from patients without obstetric history of neonatal lupus to cause heart block using an experimental model was investigated. IgG-enriched fractions from sera of 20 systemic lupus erythematosus (SLE) and one Sjögren's syndrome (SS) all positives for anti-Ro/SSA antibodies as detected by CIE, were perfused on isolated whole rabbit hearts. Only six (29%) samples induced A-V block, five of them presenting low anti-Ro/SSA titre. All of them recognized the 52 kDa isoform on ELISA whereas only one had a concomitant binding to the 60 kDa protein. Moreover, affinity purified antibodies from two sera previously known to induce A-V block were obtained by affinity chromatography using a column containing the full-length 52 kDa Ro/SSA fusion protein. Paired eluate and effluent devoid of anti-52 kDa activity from the same patient were individually perfused in whole hearts. The ability to cause cardiac blockade was restricted to the affinity anti-52 kDa eluates. In addition, anti-52 kDa eluates from three IgG fractions that primarily failed to induce blockade remained ineffective. The present study has added to our knowledge that affinity anti-52 kDa Ro/SSA antibodies from mothers with healthy infants are capable of causing in vitro cardiac conduction disturbances. A prospective follow up of these patients will better delineate the clinical usefulness of this experimental model. PMID:9607636

    Desde a descoberta dos gradientes de abundância química em galáxias espirais, as regiões HII galáticas têm sido intensamente estudadas com o objetivo de determinar a forma do gradiente de abundância química na Via-Láctea. Entretanto, a forma do gradiente galático continua controversa e existem muitas regiões HII que continuam inexploradas. A região HII galática NGC 2579 é um objeto que aparece em imagens Ha, como uma pequena mancha brilhante de aproximadamente 2 segundos de arco de diâmetro a 20 segundos de arco ao leste de RCW 20, sendo NGC 2579 muitas vezes confundida com esta última. Apesar de seu alto brilho superficial, NGC 2579 é um objeto pouco estudado provavelmente por problemas de identificação deste objeto. Como parte de um projeto de reavaliação dos gradientes de abundância química das regiões HII na Via-Láctea, estamos realizando um estudo extensivo das propriedades físicas básicas como temperatura eletrônica, densidade eletrônica e composição química da região HII galática NGC 2579. Analisamos dados espectrofotométricos de fenda longa na faixa de 3700Å a 7750Å obtidos com o telescópio de 1.52 m do ESO, Chile, em 2002. Determinamos a temperatura eletrônica usando a razão entre as linhas do [OIII] (l4959+l5007/l4363) e a densidade eletrônica pela razão entre as linhas do [SII] (l6716/l6731). As abundâncias químicas do O, N, Cl, S, Ne e He foram determinadas. Realizamos um estudo de imagens fotométricas nas bandas UBVRI obtidas em 2000 no observatório astronômico San Pedro Mártir, México, para identificar e classificar as estrelas ionizantes de NGC 2579 e determinar a distância deste objeto.

    O principal objetivo deste trabalho é auxiliar o professor de Geografia em sala de aula no ensino de tópicos relacionados com a Cosmologia. A idéia deste trabalho surgiu quando foi constatado que o professor de Geografia tem dificuldades de ensinar este tópico. Esta constatação foi feita por uma das autoras ao lecionar este tópico no ensino fundamental e em discussões com outros professores de Geografia. Da mesma maneira que ocorria desde os tempos mais antigos, os alunos têm muito interesse em conhecer os fenômenos que ocorrem no Cosmo, porém os livros didáticos de Geografia utilizados em sala de aula não são ricos em informações sobre este assunto. Assim, o professor de Geografia tem poucas informações para discutir este assunto em sala de aula e não dá a devida importância para este tópico. Então, foi desenvolvido um material de apoio para professores de Geografia sobre a origem do Universo, sua evolução e seu possível futuro evolutivo segundo as mais recentes teorias, com base em perguntas feitas pelos alunos de ensino fundamental e as informações trazidas nos livros didáticos Não cabe a este material inovar e tão pouco trazer uma metodologia de ensino de Cosmologia. Neste material o professor de Geografia pode encontrará um banco de informações, que constitui no estabelecimento de conceitos, teorias e hipóteses, sobre a Cosmologia, em linguagem simples e de fácil entendimento. Para desenvolvê-lo, foram feitas pesquisas não exaustivas em livros e revistas científicas, compilação e discussão em forma cronológica das teorias aceitas sobre modelos cosmológicos. Portanto, este material será apresentado neste trabalho.

    After a scheduled maintenance and upgrade period, the world’s largest and most powerful machine - the Large Hadron Collider(LHC) - is about to enter its second run at unprecedented energies. In order to exploit the scientific potential of the machine, the experiments at the LHC face computational challenges with enormous data volumes that need to be analysed by thousand of physics users and compared to simulated data. Given diverse funding constraints, the computational resources for the LHC have been deployed in a worldwide mesh of data centres, connected to each other through Grid technologies. The PanDA (Production and Distributed Analysis) system was developed in 2005 for the ATLAS experiment on top of this heterogeneous infrastructure to seamlessly integrate the computational resources and give the users the feeling of a unique system. Since its origins, PanDA has evolved together with upcoming computing paradigms in and outside HEP, such as changes in the networking model, Cloud Computing and HPC. It ...

    We have previously demonstrated that low dose of inhaled dopamine (0.5-2 microg kg(-1) min(-1)) induces broncodilatacion in patients with acute asthma attack, suggesting that this dopamine effect is mediated by dopaminergic rather than by adrenergic receptors. To understand better these dopamine effect, rat tracheal smooth muscle was used as a model to evaluate the responses of beta2-, alpha1-, alpha2-adrenergic and DA1 and DA2 dopaminergic antagonists. Tracheal rings from male Sprague-Dawley rats (n = 90) were excised and placed in an organ bath containing modified Krebs-Ringer bicarbonate buffer at 37 degrees C, and gassed with O2 (95%) and CO2 (5%). Contractile responses were recorded with an isometric transducer in a polygraph (Letica, Spain). Contraction was induced by accumulative doses of acetylcholine (0.1, 0.3, 1, 3, 10 mM) or by electric field stimulation (10 Hz at 2 milliseconds), and accumulative doses of dopamine were added to the bath. Low concentration (0.1-0.3 mM) elicited a small initial contraction, followed by a marked relaxation. Cholinergic contraction was completely reversed at 6 mM of dopamine. This biphasic dopaminergic response was not blocked by incubation with beta2-adrenergic antagonist propranolol (0.1 microM), alpha1-antagonist, terazosin (0.1 mM), alpha2-antagonist, yohimbine (0.1 mM), or by DA2 antagonist metoclopramide (1-8 mM); DA1 antagonist SCH23390 (0.1 microM) produced a sustained increase of basal tone but did not block initial dopaminergic contraction and partially inhibited bronchodilator effect of dopamine. Dopaminergic relaxation in rat trachea is mediated by DA1 rather than by DA2 receptors; and adrenergic receptors are not involved in such dopamine-induced response. Finally, DA1 antagonist SCH23390 exerts intrinsic contractile activity on airway smooth muscle that deserves further research. PMID:20496460

    Human autoantibodies to intracellular antigens are often found in patients with systemic rheumatic diseases. Our laboratory and others have reported the cloning of the cDNAs for two protein autoantigens. The 60-kDa protein is a member of the RNA binding protein family containing an RNA binding motif and has been shown to be primarily responsible for direct interaction with hY-RNAs. The assignment of the 60-kDa autoantigen gene (SSA2) to 1q31 may allow further investigation of the genetic basis of human autoimmune diseases in which ss-A/Ro antibodies are observed. 14 refs., 1 fig.

    The current tendency of microsurgery is heading toward supermicrosurgery and microsurgery assisted by robotics. The aim of this work was to study the feasibility of a free hallux hemipulp transfer with a surgical robot in a cadaveric model. We used a human body. The intervention was realized by a Da Vinci SI® robot (Intuitive Surgical™, Sunnyvale, CA) in two stages: first taking off the medial hallux hemipulp, then transferring the hallux hemipulp to the radial thumb hemipulp. The intervention lasted 1 hour 59 minutes, exclusively with the Da Vinci SI® robot, without any interruption or outside intervention. Despite the absence of sensory feedback and an intervention 25% longer than in conventional microsurgery, we have demonstrated the feasibility of free hallux hemipulp transfer with a surgical robot. In the future, it is likely that the added benefits of the robot (physiological tremor suppression, user-friendly ergonomics, ultraprecise control of the instruments) will make the robot an indispensable tool for the surgeon.

    Objectives Current robotic training approaches lack criteria for automatically assessing and tracking (over time) technical skills separately from clinical proficiency. We describe the development and validation of a novel automated and objective framework for assessment of training. Methods We are able to record all system variables (stereo instrument video, hand and instrument motion, buttons and pedal events) from the da Vinci surgical systems using a portable archival system integrated with the robotic surgical system. Data can be collected unsupervised, and the archival system does not change system operation in any way. Our open-ended multi-center protocol is collecting surgical skill benchmarking data from 24 trainees to surgical proficiency, subject only to their continued availability. Two independent experts performed structured (OSATS) assessments on longitudinal data from 8 novice and 4 expert surgeons to generate ground truth for training and to validate our computerized statistical analysis methods in identifying ranges of operational and clinical skill measures. Results Objective differences in operational and technical skill between known experts and other subjects were quantified. Longitudinal learning curves and statistical analysis for trainee performance measures are reported. Graphical representations of skills developed for feedback to the trainees are also included. Conclusions We describe an open-ended longitudinal study and automated motion recognition system capable of objectively differentiating between clinical and technical operational skills in robotic surgery. Our results demonstrate a convergence of trainee skill parameters towards those derived from expert robotic surgeons over the course of our training protocol. PMID:22172215

    A biogeochemical forecasting system of the North and Baltic Seas is developed based on the HIROMB-BOOS circulation Model (HBM) coupled with the ERGOM ecosystem model and augmented by observational data assimilation (DA). The DA system is built within the Parallel Data Assimilation Framework (http://pdaf.awi.de). In the frame of ensemble based DA techniques, we consider various aspects and strategies of the biogeochemical state and parameter estimation when assimilating MODIS satellite chlorophyll "a" and NOAA's sea surface temperature observations. In particular, we discuss identification of crucial ecosystem parameters, assumed stoichiometry and scaling biogeochemical variables in the presence of non-Gaussianity.

    Few geomagnetic ground observations exist of the Earth's strongest core field anomaly, the South Atlantic Anomaly (SAA). The geomagnetic repeat station on the island Tristan da Cunha, located half-way between South Africa and South America at 37?? 05' S, 12?? 18' W, is therefore of crucial importance. We have conducted several sets of repeat station measurements during magnetically quiet conditions (Kp 2o or less) in 2004. The procedures are described and the results are compared to those from earlier campaigns and to the predictions of various global field models. Features of the local crustal bias field and the solar quiet daily variation are discussed. We also evaluate the benefit of continuous magnetic field recordings from Tristan da Cunha, and argue that such a data set is a very valuable addition to geomagnetic satellite data. Recently, funds were set up to establish and operate a magnetometer station on Tristan da Cunha during the Swarm magnetic satellite mission (2011-2014).

    The history of flow-visualization (FV) techniques is traced, and current methods are characterized, in a survey of recently published reviews and monographs. Consideration is given to the FVs used by da Vinci, Reynolds, and Prandtl; the differences between FV methods for liquids and for gases; FV of basic phenomena; FV of convective heat transfer and two-phase flow; and computer-aided FV. Typical FV results are presented graphically.

The dominant influence over political psychology in the next three decades became psychoanalytic theory. During this time period..., there was a tremendous growth in the prevalence of psychohistories.

    Previously, anatomists considered paranasal sinuses as a mysterious region of the human skull. Historically, paranasal sinuses were first identified by ancient Egyptians and later, by Greek physicians. After a long period of no remarkable improvement in the understanding of anatomy during the Middle Ages, anatomists of the Renaissance period-Leonardo da Vinci and Vesalius-made their own contribution. Nathaniel Highmore's name is also associated with the anatomy of paranasal sinuses as he was first to describe the maxillary sinus. PMID:24386595

    Variáveis Cataclísmicas são sistemas binários cerrados compostos de uma anã vermelha que transfere matéria para uma anã branca, em sistemas não magnéticos ocorre a formação de um disco de acresção em torno da anã branca. V3885 Sgr é uma variável cataclísmica classificada como sendo do tipo nova-like. É apresentado um estudo espectrofotométrico de V3885 Sgr de alta resolução temporal feito na região do visível. A região observada é centrada em Ha e abrange também a linha de HeI 6678. O primeiro resultado obtido neste estudo é a determinação do período orbital a partir de medidas da velocidade radial da linha de Ha como sendo 0,20716071(22) dias, resolvendo inconsistências quanto a esse valor na literatura e definindo uma efeméride a longo prazo para o sistema. Com este período e as medidas de velocidade radial do perfil de linha de Ha foi construído um diagrama de massas, através do qual restringimos as massas das componentes estelares do sistema e limitamos a inclinação orbital do sistema. Foram construídos diagramas de Greenstein para as linhas de Ha e HeI, onde os espectros médios em cada intervalo de fase são representados lado a lado em escala de cinza, indicando a existência de uma emissão intensa proveniente da parte posterior do disco. A partir da tomografia Doppler obtivemos perfis de emissividade radial para o disco tanto para a linha de Ha como para HeI. Os resultados obtidos são comparados com os de outros sistemas estudados com a mesma técnica. Serão apresentados também resultados da tomografia de flickering para o sistema.

    Human interaction environments (HIE) must be understood as any place where people carry out their daily life, including their work, family life, leisure and social life, interacting with technology to enhance or facilitate the experience. The integration of technology in these environments has been achieved in a disorderly and incompatible way, with devices operating in isolated islands with artificial edges delimited by the manufacturers. In this paper we are presenting the UniDA framework, an integral solution for the development of systems that require the integration and interoperation of devices and technologies in HIEs. It provides developers and installers with a uniform conceptual framework capable of modelling an HIE, together with a set of libraries, tools and devices to build distributed instrumentation networks with support for transparent integration of other technologies. A series of use case examples and a comparison to many of the existing technologies in the field has been included in order to show the benefits of using UniDA. PMID:22163700

  1. Autoantibody to the leucine zipper region of 52 kDa Ro/SSA binds native 60 kDa Ro/SSA: identification of a tertiary epitope with components from 60 kDa Ro/SSA and 52 kDa Ro/SSA.

    PubMed

    Anti-Ro (or SSA) is found in the sera of patients with autoimmune rheumatic illnesses. All patients with anti-Ro defined by precipitation bind a 60 000 Da antigen (60 kDa Ro), whereas some patients also bind a 52 000 Da molecule (52 kDa Ro). In general, antibody binding is directed against native 60 kDa Ro and denatured 52 kDa Ro. The mechanism by which anti-52 kDa Ro arises in the setting of anti-60 kDa Ro is unknown. Conflicting data exist as to the existence of a physical interaction between the two proteins in cells and as to cross-reacting antibodies. Antibodies were affinity purified from a peptide within the leucine zipper region of 52 kDa Ro. These purified antibodies binding the 197-207 peptide from 52 kDa Ro (anti-52LZ) bound native 60 kDa Ro as well as denatured 52 kDa Ro. In addition, anti-52LZ also bound up to four regions from the sequence of 60 kDa Ro and a single conformational epitope of 60 kDa Ro. Thus, these primary sites represent components of the tertiary epitope. We hypothesized that if this was the case, these peptides making up a tertiary epitope would show molecular interaction. In fact, peptides from 60 kDa Ro have a molecular interaction with the 52 kDa Ro peptide as well as full-length 52 kDa Ro when assessed by surface plasmon resonance. The leucine-zipper region peptide from 52 kDa Ro bound three of the four peptides from 60 kDa Ro. These data suggest that these two molecular species, 60 and 52 kDa Ro, form a conformational epitope. This relationship may explain why anti-52 kDa Ro is found in association with anti-60 kDa Ro. PMID:11251884

  2. Robotic surgery: urologic implications.

    Moran, Michael E

    2003-11-01

    Current medical robots have nothing in common with the anthropomorphic robots in science fiction classics. They are in fact, manipulators, working on a master-slave principle. Robots can be defined as "automatically controlled multitask manipulators, which are freely programmable in three or more spaces." The success of robots in surgery is based on their precision, lack of fatigue, and speed of action. This review describes the theory, advantages, disadvantages, and clinical utilization of mechanical and robotic arm systems to replace the second assistant and provide camera direction and stability during laparoscopic surgery. The Robotrac system (Aesculap, Burlingame, CA), the First Assistant (Leonard Medical Inc, Huntingdon Valley, PA), AESOP (Computer Motion, Goleta, CA), ZEUS (Computer Motion), and the da Vinci (Intuitive Surgical, Mountain View, CA) system are reviewed, as are simple mechanical-assist systems such as Omnitract (Minnesota Scientific, St. Paul, MN), Iron Intern (Automated Medical Products Corp., New York, NY), the Bookwalter retraction system (Codman , Somerville, NJ), the Surgassistant trade mark (Solos Endoscopy, Irvine, CA), the Trocar Sleeve Stabilizer (Richard Wolf Medical Instruments Corp., Rosemont, IL), and the Endoholder (Codman, Somerville, NJ).

    2009-01-01

    Background Minimally invasive surgery has become more and more important in modern hospitals. In this context, increasingly more surgeons need to be trained to master the necessary laparoscopic surgical skills. The Fundamentals of Laparoscopic Surgery (FLS) training tool box has now been adopted by the Society of Gastrointestinal Endoscopic Surgeons (SAGES) as an official training tool. While useful, there are major drawbacks of such physical tool boxes including the need to constantly replace training materials, inability to perform objective quantification of skill and the inability to easily adapt to training surgeons on surgical robots such as the da Vinci® which provides high resolution stereo visualization. Methods To overcome the limitations of the FLS training tool box, we have developed a Virtual Basic Laparoscopic Skill Trainer (VBLaST™) system, which will allow trainees to acquire basic laparoscopic skill training through the bimanual performance of four tasks including peg transfer, pattern cutting, ligating loop and suturing. A high update rate of about 1 kHz is necessary to ensure continuous haptic interactions and smooth transitions. Results The outcome of this work is the development of an integrated visio-haptic workstation environment including two Phantom® Omni™ force feedback devices and a 3D display interface from Planar Systems, Inc whereby trainees can practice on virtual versions of the FLS tasks in 2D as well as in 3D, thereby allowing them to practice both for traditional laparoscopic surgery as well as that using the da Vinci® system. Realistic graphical rendering and high fidelity haptic interactions are achieved through several innovations in modeling complex interactions of tissues and deformable objects. Conclusions Surgical skill training is a long and tedious process of acquiring fine motor skills. Even when complex and realistic surgical trainers with realistic organ geometries and tissue properties, which are currently being developed by academic researchers as well as the industry, mature to the stage of being routinely used in surgical training, basic skill trainers such as VBLaST™ will not lose their relevance. It is expected that residents would start on trainers such as VBLaST™ and after reaching a certain level of competence would progress to the more complex trainers for training on specific surgical procedures. In this regard, the development of the VBLaST™ is highly significant and timely. PMID:18348181

    The faint (g = 16.9) hot white dwarf BOKS 53856 was observed by the Kepler Mission in short cadence mode during mid-2009. Analysis of these observations reveals a highly stable modulation with a period of 6.1375 hr and a 2.46% half-amplitude. The folded light curve has an unusual shape that is difficult to explain in terms of a binary system containing an unseen companion more luminous than an L0 brown dwarf. Optical spectra of BOKS 53856 show a T{sub eff} = 34,000 K, log g = 8.0 DA white dwarf. There are few, if any, known white dwarfs in this temperature range exhibiting photometric variations similar to those we describe. A magnetic spin-modulated white dwarf model can in principle explain the light curve, an interpretation supported by spectral observations of the H{alpha} line showing evidence of Zeeman splitting.

    Observations are reported which refine the binary ephemeris of the Feige 24 system, which contains a peculiar hot DA white dwarf and an M dwarf with an atmosphere illuminated by extreme ultraviolet radiation from the white dwarf. With the new ephemeris and a set of IUE high-dispersion spectra, showing phase-dependent redshifted C IV, N V, and Si IV resonance lines, the orbital velocity, and hence the mass (0.54 + or - 0.20 solar masses), and the gravitational redshift of the white dwarf (14.1 + or - 5.2 km/s) are determined independently. It is shown that the measured Einstein redshift is consistent with an estimated radius for the white dwarf obtained from a model atmosphere solid angle and a parallax measurement. This radius is twice the Hamada-Salpeter radius for the given mass and offers a prospect to investigate the presence of a massive hydrogen envelope in that white dwarf star.

    2010-10-20

    This final report details the components, functionality, costs, schedule and benefits of developing an Integrated Distribution Management System (IDMS) for power distribution system operation. The Distribution Automation (DA) and Supervisory Control and Data Acquisition (SCADA) systems used by electric power companies to manage the distribution of electric power to retail energy consumers are vital components of the Nation’s critical infrastructure. Providing electricity is an essential public service and a disruption in that service, if not quickly restored, could threaten the public safety and the Nation’s economic security. Our Nation’s economic prosperity and quality of life have long depended on the essential services that utilities provide; therefore, it is necessary to ensure that electric utilities are able to conduct their operations safely and efficiently. A fully integrated technology of applications is needed to link various remote sensing, communications and control devices with other information tools that help guide Power Distribution Operations personnel. A fully implemented IDMS will provide this, a seamlessly integrated set of applications to raise electric system operating intelligence. IDMS will enhance DA and SCADA through integration of applications such as Geographic Information Systems, Outage Management Systems, Switching Management and Analysis, Operator Training Simulator, and other Advanced Applications, including unbalanced load flow and fault isolation/service restoration. These apps are capable of utilizing and obtaining information from appropriately installed DER, and by integrating disparate systems, the Distribution Operators will benefit from advanced capabilities when analyzing, controlling and operating the electric system.

    Trans-esophageal echocardiography (TEE) is a standard component of patient monitoring during most cardiac surgeries. In recent years magnetic tracking systems (MTS) have become sufficiently robust to function effectively in appropriately structured operating room environments. The ability to track a conventional multiplanar 2D TEE transducer in 3D space offers incredible potential by greatly expanding the cumulative field of view of cardiac anatomy beyond the limited field of view provided by 2D and 3D TEE technology. However, there is currently no TEE probe manufactured with MTS technology embedded in the transducer, which means sensors must be attached to the outer surface of the TEE. This leads to potential safety issues for patients, as well as potential damage to the sensor during procedures. This paper presents a standard 2D TEE probe fully integrated with MTS technology. The system is evaluated in an environment free of magnetic and electromagnetic disturbances, as well as a clinical operating room in the presence of a da Vinci robotic system. Our first integrated TEE device is currently being used in animal studies for virtual reality-enhanced ultrasound guidance of intracardiac surgeries, while the "second generation" TEE is in use in a clinical operating room as part of a project to measure perioperative heart shift and optimal port placement for robotic cardiac surgery. We demonstrate excellent system accuracy for both applications.

  10. Photolabeling of a 150-kDa (Na + K + Cl) cotransport protein from dog kidney with a bumetanide analogue

    Haas, M.; Forbush, B. III

    1987-08-01

    (Na + K + Cl) cotransport is the major mechanism of salt transport across the apical membrane of the epithelial cells of the thick ascending limb of Henle's loop of mammalian kidney and the site of action of loop diuretics such as furosemide and bumetanide. We have identified a 150-kDa protein in membranes from dog kidney cortex that is photolabeled by a radiolabeled, benzophenone analogue of bumetanide, (/sup 3/H)4-benzoyl-5-sulfamoyl-3-(3-thenyloxy)benzoic acid ((/sup 3/H)BSTBA). Several pieces of evidence strongly suggest that this 150-kDa protein is at least part of the (Na + K + Cl) cotransport system. 1) Photoincorporation of (/sup 3/H)BSTBA into this protein is completely blocked by inclusion of 10 microM unlabeled bumetanide in the photolysis medium. 2) Photoincorporation of (/sup 3/H)BSTBA into this protein shows a saturable dependence on (/sup 3/H)BSTBA concentration, with a K 1/2 (approximately 0.1 microM) very similar to that for reversible (/sup 3/H)BSTBA binding to kidney membranes. 3) Photolabeling of this protein by (/sup 3/H)BSTBA requires the simultaneous presence of Na, K, and Cl in the photolysis medium. 4) When crude membranes from dog kidney cortex are centrifuged on sucrose density gradients, saturable (/sup 3/H)bumetanide binding and photoincorporation of (/sup 3/H)BSTBA in the 150-kDa region show a very similar distribution among the 15 gradient fractions collected. (/sup 3/H)BSTBA is also photoincorporated into at least two lower molecular mass proteins, the largest of which is approximately 50 kDa.

    From Leonardo da Vinci?s designs for ball bearings to the incredible engineering wizardry behind the Ferrari, the inventive, inquisitive, and ingenious spirit of the engineer has always lived?and thrived?in Italy. From education to research to product development, Italy has always been regarded as an engineering leader. But does this apply to biomedical engineering (BME)? Despite many successes, questions loom, as they do at engineering schools worldwide. Concerns such as whether BME programs are providing students with enough focused, practical, handson training remain at the forefront, as does the question of whether graduates will be able to find jobs in industry after university studies are over. Here, IEEE Pulse explores these topics with Riccardo Pietrabissa, president of the Gruppo Nazionale di Bioingegneria (National Bioengineering Group) and a full professor in the Department of Chemistry, Materials, and Chemical Engineering at Politecnico di Milano.

  4. Domain annotation of trimeric autotransporter adhesins—daTAA

    PubMed Central

    Szczesny, Pawel; Lupas, Andrei

    2008-01-01

    Motivation: Trimeric autotransporter adhesins (TAAs), such as Yersinia YadA, Neisseria NadA, Moraxella UspAs, Haemophilus Hia and Bartonella BadA, are important pathogenicity factors of proteobacteria. Their high sequence diversity and distinct mosaic-like structure lead to difficulties in the annotation of their sequences. These stem from the large number of short repeats, the presence of compositionally unusual coiled-coils, fuzzy domain boundaries and regions of seemingly low sequence complexity. Results: We have developed a workflow, named daTAA, for the accurate domain annotation of TAAs. Its core consists of manually curated alignments and of knowledge-based rules that enhance assignments made by sequence similarity. Compared to general domain annotation servers such as PFAM, daTAA captures more domains and provides more sensitive domain detection, as well as integrated and detailed coiled-coil assignments. Availability: The daTAA server is freely accessible at http://toolkit.tuebingen.mpg.de/dataa Contact: andrei.lupas@tuebingen.mpg.de Supplementary information: Supplementary data are available at Bioinformatics online.

    Prenatal stress exerts a strong impact on fetal brain development in rats impairing adaptation to stressful conditions, subsequent vulnerability to anxiety, altered sexual function, and enhanced propensity to self-administer drugs. Most of these alterations have been attributed to changes in the neurotransmitter dopamine (DA). In humans; dysfunction of dopaminergic system is associated with development of several neurological disorders, such as Parkinson disease, schizophrenia, attention-deficit hyperactivity disorder, and depression. Evidences provided by animal research, as well as retrospective studies in humans, pointed out that exposure to adverse events in early life can alter adult behaviors and neurochemical indicators of midbrain DA activity, suggesting that the development of the DA system is sensitive to disruption by exposure to early stressors. The purpose of this article is to provide a general overview of published studies and our own study related to the effect of prenatal insults on the development of DA metabolism and biology, focusing mainly in articles involving prenatal-restraint stress protocols in rats. We will also attempt to make a correlation between theses alterations and DA-related pathological processes in humans. PMID:22215534

    Master-slave manipulators enhance surgeons' dexterity and improve the precision of surgical techniques by filtering out surgeons' tremors and scaling the movements of surgical instruments. Among clinically available master-slave manipulators, the epoch-making system called "da Vinci" developed by Intuitive Surgical Inc. (Mountain View, CA, USA), equipped with 2 articulated joints at the tip of the surgical instruments allowing 7 degrees of freedom, mimics the movements of surgeons' wrists and fingers in the abdominal or thoracic cavity. Today advanced telecommunications technology provides us excellent motion images using only 3-ISDN telephone lines. Experienced surgeons at primary surgical sites have been able to perform complex procedures successfully by consulting specialists at remote sites. Because telecommunications costs have become lower each year, telementoring will be come a routine surgical practice in the near future. The usefulness of surgical telementoring has been greatly enhanced by the development of a technique to illustrate on video images from two directions. Moreover, remote advisory surgeons will be able to provide the optimal operative field to operating surgeons using robotic camera holders with voice-recognition systems. In the near future, when master-slave manipulators will also be coupled with telementoring systems, remote experts could actually perform complex surgical procedures. PMID:10773995

  16. Noradrenergic and dopaminergic systems in the central nervous system of the hedgehog (Erinaceus europaeus).

    1996-01-01

    The distribution of the noradrenaline (NA)- and dopamine (DA)-containing neuronal structures in the central nervous system of the hedgehog (Erinaceus europaeus), a phylogenetically old mammalian species, was immunocytochemically studied employing antibodies directed against the catecholamines (CA) themselves. Groups of DA cell bodies observed in this study were similar to those present in other species but the distributional map of the NA-containing cell bodies exhibited some peculiarities. Prominent among them were the absence of the A3 group and the paucity of CA cells in the A2 group. DA neurons in the hypothalamus, apart from the densely populated paraventricular and arcuate nuclei, were fewer and less widely distributed than in other species. In the hedgehog mesencepha- Ion, in contrast to what has been described in other species, the major DA cell group was present in the ventral tegmental area. CA immunoreactive fibers were widely distributed in the CNS of the hedgehog. However, similarly to what has been observed in other species, terminal fields of DA neurons were much more restricted when compared to those of the NA neurons. The neocortical DA projection system of the hedgehog appeared less developed but organized similar to that of the rat, and even less developed than that of the primates. The lack of profound regional and laminar variations in the density of cortical NA fibers in the hedgehog enhances the suggestion that the elaboration and differentiation of the NA cortical system parallels the phylogenetic development of the cortex. In the brainstem, interspecies differences in the distribution of the CA fibers were found to concern primarily some hypothalamic areas (medial preoptic area, suprachiasmatic nucleus, arcuate nucleus). Such differences in the thalamus concerned the NA innervation and they were notably present in the visual thalamic nuclei (dorsal lateral geniculate nucleus, lateral posterior thalamic nucleus). In the spinal cord, which was found to receive fewer CA afferents than those found in other species, the density of the DA fibers was much lower than that of the NA axons. In addition to the CNS areas that have been described in other species to receive catecholaminergic innervation, the present study showed that both types of catecholaminergic fibers are distributed in the choroid plexus and along the ventricular wall of the brain ventricles and the central canal of the hedgehog.

    Repeated stress engenders behavioral sensitization. The mesolimbic dopamine system is critically involved in drug-induced behavioral sensitization. In the present study we examined the differences between adolescent and adult rats in stress-induced behavioral sensitization to amphetamine and changes in dopamine (DA) and its metabolite levels in the mesolimbic system. Adolescent or adult rats were restrained for 2 h, once a day, for 7 days. Three days after the last exposure to stress, the animals were challenged with saline or amphetamine (1.0 mg/kg i.p.) and amphetamine-induced locomotion was recorded for 40 min. Immediately after the behavioral tests, rats were decapitated and the nucleus accumbens (NAcc), ventral tegmental area (VTA) and amygdala (AM) were removed to measure tissue levels of DA and its metabolites by HPLC. Exposure to repeated restraint stress promoted behavioral sensitization to amphetamine in both adult and adolescent rats. In adult rats, amphetamine administration increased DA levels in both the stress and control groups in the NAcc and VTA. In adolescent rats, amphetamine increased DA levels in the NAcc in rats exposed to stress. Furthermore, in the AM of adolescent rats in the control group, amphetamine increased the DA levels; however, amphetamine reduced this neurotransmitter in the rats that were exposed to stress. No alteration was observed in the dopamine metabolite levels. Therefore, stress promoted behavioral sensitization to amphetamine and this may be related to changes in DA levels in the mesolimbic system. These changes appear to be dependent on ontogeny.

  1. Extended space method for parameter identifiability of DAE systems.

    PubMed

    2014-09-01

    Mathematical models of physical systems often have parameters that must be identified from physical data. This makes the analysis of the parameter identifiability of the given model system an essential prerequisite. Thus far, several methods have been proposed for analyzing the parameter identifiability of ordinary differential equation (ODE) systems. But, to the best of our knowledge, the parameter identifiability of differential algebraic equation (DAE) systems has scarcely been analyzed as a specific topic. Traditional differential algebraic (DA) methods developed for ODE systems are often applied directly on DAE systems. These methods, however, are not always applicable, e.g., when the prime ideal condition is not satisfied by a DAE system. In this paper, we propose a novel method to analyze the identifiability of DAE systems, based on the concept of space extension, through which the algebraic and differential variables can be decoupled. Furthermore, an inherent, low-dimensional, regular ODE system can be obtained, which is the external equivalent of the original DAE system. Subsequently, the differential algebraic (DA) method can then be used to analyze the identifiability of the low-dimension ODE system. Theoretical analysis is also presented for the proposed method. Two examples, including a simplified interaction model and an isothermal reactor system, are presented to illustrate the detailed steps and effectiveness of the proposed method. PMID:24411933

    Ro60 kDa is a member of the Ro/LaRNP ribonucleoprotein complex and its major linear B cell epitope, corresponding to the region 169-190aa, has been found to be the initial target of the autoimmune response in patients with systemic lupus erythematosus. This sequence contains one serine and two arginine amino acid residues, which can potentially be modified post-translationally by phosphorylation or citrullination, respectively. The aim of this study was to develop an immunoassay for anti-Ro60 kDa epitope antibody detection and to investigate the changes in the antigenicity of the Ro60 kDa epitope when it is post-translationally modified, by either citrullination or phosphorylation. Peptide analogues corresponding to the unmodified form of the epitope, its phosphorylated form, and a form with both arginine residues citrullinated were synthesized. The peptide coating conditions were investigated and it was found that the use of highly hydrophilic surfaces increase the efficiency of the coating, as well as the sensitivity of the method for anti-peptide antibody detection. All peptides were tested by the optimized enzyme-linked immunosorbent assay (ELISA) against 119 sera from patients with primary Sjögren's syndrome, systemic lupus erythematosus and rheumatoid arthritis with anti-Ro/SSA reactivity, 20 sera from patients with systemic diseases without anti-Ro/SSA immune reactivity, as well as against 65 sera from normal individuals. A large proportion of the tested sera reacted against all three peptide analogues, although with a preference for the unmodified form of the epitope. In conclusion, post-translational modifications of the major Ro60 kDa B cell epitope can alter the autoantibody binding. PMID:16968399

    We present a portable, multimodal, nonlinear endo-microscopy probe designed for intraoperative oncological imaging. Application of a four-wave mixing noise suppression scheme using dual wavelength wave plates (DWW) and a polarization-maintaining fiber improves tissue signal collection efficiency, allowing for miniaturization. The probe, with a small 14 mm transversal diameter, includes a customized miniaturized two-axis MEMS (micro-electromechanical system) raster scanning mirror and micro-optics with an illumination laser delivered by a polarization-maintaining fiber. The probe can potentially be integrated into the arms of a surgical robot, such as da Vinci robotic surgery system, due to its minimal cross sectional area. It has the ability to incorporate multiple imaging modalities including CARS (coherent anti-Stokes Raman scattering), SHG (second harmonic generation), and TPEF (two-photon excited fluorescence) in order to allow the surgeon to locate tumor cells within the context of normal stromal tissue. The resolution of the endo-microscope is experimentally determined to be 0.78 µm, a high level of accuracy for such a compact probe setup. The expected resolution of the as-built multimodal, nonlinear, endo-microscopy probe is 1 µm based on the calculation tolerance allocation using Monte-Carlo simulation. The reported probe is intended for use in laparoscopic or radical prostatectomy, including detection of tumor margins and avoidance of nerve impairment during surgery.

    In July 2000, the da Vinci Surgical System (Intuitive Surgical, Inc) received Food and Drug Administration approval for intracardiac applications, and the first mitral valve repair was done at the East Carolina Heart Institute in May 2000. The system is now approved and used in many surgical specialties. With this disruptive technology and accepted use, surgeons and hospitals are seeking the most efficacious training pathway leading to safe use and responsible credentialing.One of the most important issues related to safe use is assembling the appropriate team of professionals involved with patient care. Moreover, proper patient selection and setting obtainable goals are also important.Creation and maintenance of a successful program are discussed in the article focusing on realistic goals. This begins with a partnership between surgeon leaders, hospital administrators, and industry support. Through this partnership, an appropriate training pathway and clinical pathway for success can be outlined. A timeline can then be created with periods of data analysis and adjustments as necessary. A successful program is attainable by following this pathway and attending to every detail along the journey. PMID:23528718

    FDA approved Da Vinci Surgical System in 2005 for gynecological surgery. It has been rapidly adopted and it has already assumed an important position at various centers where this is available. It comprises of three components: A surgeon's console, a patient-side cart with four robotic arms and a high-definition three-dimensional (3D) vision system. In this review we have discussed various robotic-assisted laparoscopic benign gynecological procedures like myomectomy, hysterectomy, endometriosis, tubal anastomosis and sacrocolpopexy. A PubMed search was done and relevant published studies were reviewed. Surgeries that can have future applications are also mentioned. At present most studies do not give significant advantage over conventional laparoscopic surgery in benign gynecological disease. However robotics do give an edge in more complex surgeries. The conversion rate to open surgery is lesser with robotic assistance when compared to laparoscopy. For myomectomy surgery, Endo wrist movement of robotic instrument allows better and precise suturing than conventional straight stick laparoscopy. The robotic platform is a logical step forward to laparoscopy and if cost considerations are addressed may become popular among gynecological surgeons world over. PMID:25598600

    Background The number of robotic operations performed with the da Vinci Surgical System has increased during the past decade. This system allows for greater maneuverability and control than hand-assisted laparoscopic procedures, resulting in less tissue manipulation and irritation. Methods We retrospectively analyzed the results of 100 consecutive robotic-assisted laparoscopic donor nephrectomies and compared them to our most recent 20 hand-assisted laparoscopic donor nephrectomies. Results Between May 2008 and June 2012, 120 laparoscopic donor nephrectomies were performed at Ochsner Clinic Foundation. Of those, 100 live kidney donors underwent robotic-assisted laparoscopic donor nephrectomies. Surgical time and hospital length of stay improved after the first 20 patients receiving robotic-assisted laparoscopic nephrectomies, which was considered the learning curve. Sixty percent of patients who underwent robotic-assisted laparoscopic donor nephrectomies were released on postoperative day 1 compared to 45% of patients who underwent hand-assisted laparoscopic techniques. Conclusion In our experience, robotic-assisted laparoscopic donor nephrectomy resulted in decreased postoperative length of stay that decreased the global cost of the procedure and allowed our institution to admit more patients.

  8. The Role of Robotic Surgery for Rectal Cancer: Overcoming Technical Challenges in Laparoscopic Surgery by Advanced Techniques.

    2015-07-01

    The conventional laparoscopic approach to rectal surgery has several limitations, and therefore many colorectal surgeons have great expectations for the robotic surgical system as an alternative modality in overcoming challenges of laparoscopic surgery and thus enhancing oncologic and functional outcomes. This review explores the possibility of robotic surgery as an alternative approach in laparoscopic surgery for rectal cancer. The da Vinci® Surgical System was developed specifically to compensate for the technical limitations of laparoscopic instruments in rectal surgery. The robotic rectal surgery is associated with comparable or better oncologic and pathologic outcomes, as well as low morbidity and mortality. The robotic surgery is generally easier to learn than laparoscopic surgery, improving the probability of autonomic nerve preservation and genitourinary function recovery. Furthermore, in very complex procedures such as intersphincteric dissections and transabdominal transections of the levator muscle, the robotic approach is associated with increased performance and safety compared to laparoscopic surgery. The robotic surgery for rectal cancer is an advanced technique that may resolve the issues associated with laparoscopic surgery. However, high cost of robotic surgery must be addressed before it can become the new standard treatment. PMID:26130943

    Laparoscopic cholecystectomy is widely considered as the treatment of choice for acute cholecystitis. The safety of the procedure and its minimal invasiveness made it a valid treatment option for a patient not responding to antibiotic therapy. Our research shows that patients positively assess this treatment method, but the world's tendency is to turn to a more sophisticated method utilizing robot-assisted surgery as a gold standard. Providing patient with minimally invasive surgical procedures that utilize the state-of-the-art equipment like the da Vinci Robotic Surgical System underscores the commitment to high-quality patient care while enhancing patient safety. The advantages include minimal invasive scarring, less pain and bleeding, faster recovery time, and shorter hospital stay. The move toward less invasive and less morbid procedures and a need to re-create the true open surgical experience have paved the way for the development and application of robotic and computer-assisted systems in surgery in Poland as well as the rest of the world.

    Robotic laparoscopy in gynecology, which started in 2005 when the Da Vinci Surgical System (Intuitive Surgical Inc) was approved by the US Food and Drug Administration for use in gynecologic procedures, represents today a modern, safe, and precise approach to pathology in this field. Since then, a great deal of experience has accumulated, and it has been shown that there is almost no gynecological surgery that cannot be approached with this technology, namely hysterectomy, myomectomy, sacrocolpopexia, and surgery for the treatment of endometriosis. Albeit no advantages have been observed over conventional laparoscopy and some open surgical procedures, robotics do seem to be advantageous in highly complicated procedures when extensive dissection and proper anatomy reestablishment is required, as in the case of oncologic surgery. There is no doubt that implementation of better logistics in finance, training, design, and application will exert a positive effect upon robotics expansion in gynecological medicine. Contrary to expectations, we estimate that a special impact is to be seen in emerging countries where novel technologies have resulted in benefits in the organization of health care systems.

    Highlights: Black-Right-Pointing-Pointer Full-length 21.5-kDa MBP isoform is translocated to the nucleus. Black-Right-Pointing-Pointer We hypothesized that the exon-II-encoded sequence contained the NLS. Black-Right-Pointing-Pointer We mutated this sequence in RFP-tagged constructs and transfected N19-cells. Black-Right-Pointing-Pointer Abolition of two key positively-charged residues resulted in loss of nuclear-trafficking. Black-Right-Pointing-Pointer The 21.5-kDa isoform of classic MBP contains a non-traditional PY-NLS. -- Abstract: The predominant 18.5-kDa classic myelin basic protein (MBP) is mainly responsible for compaction of the myelin sheath in the central nervous system, but is multifunctional, having numerous interactions with Ca{sup 2+}-calmodulin, actin, tubulin, and SH3-domains, and can tether these proteins to a lipid membrane in vitro. The full-length 21.5-kDa MBP isoform has an additional 26 residues encoded by exon-II of the classic gene, which causes it to be trafficked to the nucleus of oligodendrocytes (OLGs). We have performed site-directed mutagenesis of selected residues within this segment in red fluorescent protein (RFP)-tagged constructs, which were then transfected into the immortalized N19-OLG cell line to view protein localization using epifluorescence microscopy. We found that 21.5-kDa MBP contains two non-traditional PY-nuclear-localization signals, and that arginine and lysine residues within these motifs were involved in subcellular trafficking of this protein to the nucleus, where it may have functional roles during myelinogenesis.

Most Shewanella genomes contain two nap operons: napEDABC and napDAGHB, which is an unusual feature of this genus. Two native, monomeric, 90 kDa nitrate reductase active proteins were resolved by hydrophobic interaction chromatography from aerobic cultures of Shewanella gelidimarina replete with reduced nitrogen compounds. The 90 kDa protein obtained in higher yield was characterized as NapA by electronic absorption and electron paramagnetic resonance spectroscopies and was identified by LC/MS/MS and MALDI-TOF/TOF MS as NapA from the napEDABC-type operon. The other 90 kDa protein, which was unstable and produced in low yields, was posited as NapA from the napDAGHB-type operon. Two napA genes have been sequenced from the napEDABC-type and napDAGHB-type operons of S. gelidimarina. Native NAP from S. putrefaciens was resolved as one NapA monomer and one NapAB heterodimer. Two amino acid substitutions in NapA correlated with the isolation of NAP as a NapA monomer or a NapAB heterodimer. The resolution of native, redox-active NapA isoforms in Shewanella provides new insight into the respiratory versatility of this genus, which has implications in bioremediation and the assembly of microbial fuel cells.

    Recorded in Da he wai ke (The External Medicine of Da He) in the Ming dynasty without a corresponding disease title in contemporary scholarly concepts of Traditional Chinese Medicine (TCM), Chiding disease was described as an acute symptomatic disease with inevitable serious conditions of convulsion-like or mania-like behavior, and as a refractory ailment. It was also considered as an alias of Hongsiding (namely the acute lymphangitis) in few ancient books. Matixiang, a Chinese herb for treatment of Chiding, was regarded as a nonsuch drug by Da he wai ke, and was considered as a take-then-cure drug by Chuang yang jing yan quan shu (Compendium for Experience in Sores Diseases). The present studies about Chiding and Matixiang show that: (1) the name of Chiding was first seen in Zhong zang jing (Master Hua's Classic of the Viscera) ; (2) Chiding was rarely mentioned in medical literature of the Song, Yuan and Qing Dynasty, but mostly seen in the Ming Dynasty; (3) Xinding and Huoyanding were found as synonyms of Chiding ; (4) the distinction between Chiding and Hongsiding (flaming sore) was revealed by comparison analysis of their etiology, affected part(s), symptoms, prognosis and syndromic pictures; (5) Chiding on the tongue is the same as "Tongue Ding" or "Sublingual Ding" in contemporary TCM and as "Sublingual Space Infection" in Western Medicine. Moreover, Chiding on the hands, feet or other skin parts could be classified as "Hands/Feet Ding" in contemporary TCM and as "Furuncle" (i.e., Acute Suppurative Folliculitis and Perifolliculitis or cellulites of the tongue) in Western Medicine; (6) Matixiang is probably deduced as Asarum forbesii Maxim., A. ichangense C. Y. Cheng et C. S. Yang, family Aristolochiaceae, or Valeriana jatamansi Jones., family Valerianaceae. PMID:23363849

    Since the introduction of Cyclosporine A (CsA) for immunosuppression in solid-organ transplantation, the rate of allograft rejection has decreased substantially. However, treatment with CsA induces neuropsychological complications in patients, including affective disorders such as anxiety, disorientation, depression, aggression, paranoia, and apathy. These CsA-induced affective side effects cannot be extensively studied in humans. Therefore, this study investigates the effects of intraperitoneal CsA (20 mg/kg) injections on the open-field behavior of male Dark Agouti (DA) rats 1, 6, 12, and 23 h after drug administration on 3 consecutive days. CsA induced an increase in emotionality in DA rats 6 h after injection, reflected by decreased ambulatory activity in the open field and increased defecation. In addition, a decrease in rearing activity was observed 12 h after CsA administration. These behavioral alterations are discussed in the view of changes in cytokine profiles induced by CsA.

    Sea lettuce (Ulva pertusa) is a nuisance species of green algae that is found all over the world. East-Asian species of the marine gastropod, the sea hare Aplysia kurodai, shows a clear feeding preference for sea lettuce. Compared with cellulose, sea lettuce contains a higher amount of starch as a storage polysaccharide. However, the entire amylolytic system in the digestive fluid of A. kurodai has not been studied in detail. We purified ?-amylases and ?-glucosidases from the digestive fluid of A. kurodai and investigated the synergistic action of these enzymes on sea lettuce. A. kurodai contain two ?-amylases (59 and 80 kDa) and two ?-glucosidases (74 and 86 kDa). The 59-kDa ?-amylase, but not the 80-kDa ?-amylase, was markedly activated by Ca2+ or Cl?. Both ?-amylases degraded starch and maltoheptaose, producing maltotriose, maltose, and glucose. Glucose production from starch was higher with 80-kDa ?-amylase than with 59-kDa ?-amylase. Kinetic analysis indicated that 74-kDa ?-glucosidase prefers short ?-1,4-linked oligosaccharide, whereas 86-kDa ?-glucosidase prefers large ?-1,6 and ?-1,4-linked polysaccharides such as glycogen. When sea lettuce was used as a substrate, a 2-fold greater amount of glucose was released by treatment with 59-kDa ?-amylase and 74-kDa ?-glucosidase than by treatment with 45-kDa cellulase and 210-kDa ?-glucosidase of A. kurodai. Unlike mammals, sea hares efficiently digest sea lettuce to glucose by a combination of two ?-amylases and two ?-glucosidases in the digestive fluids without membrane-bound maltase–glucoamylase and sucrase–isomaltase complexes.

    The Large Hadron Collider (LHC), operating at the international CERN Laboratory in Geneva, Switzerland, is leading Big Data driven scientific explorations. Experiments at the LHC explore the fundamental nature of matter and the basic forces that shape our universe, and were recently credited for the discovery of a Higgs boson. ATLAS and ALICE are the largest collaborations ever assembled in the sciences and are at the forefront of research at the LHC. To address an unprecedented multi-petabyte data processing challenge, both experiments rely on a heterogeneous distributed computational infrastructure. The ATLAS experiment uses PanDA (Production and Data Analysis) Workload Management System (WMS) for managing the workflow for all data processing on hundreds of data centers. Through PanDA, ATLAS physicists see a single computing facility that enables rapid scientific breakthroughs for the experiment, even though the data centers are physically scattered all over the world. The scale is demonstrated by the following numbers: PanDA manages O(102) sites, O(105) cores, O(108) jobs per year, O(103) users, and ATLAS data volume is O(1017) bytes. In 2013 we started an ambitious program to expand PanDA to all available computing resources, including opportunistic use of commercial and academic clouds and Leadership Computing Facilities (LCF). The project titled ‘Next Generation Workload Management and Analysis System for Big Data’ (BigPanDA) is funded by DOE ASCR and HEP. Extending PanDA to clouds and LCF presents new challenges in managing heterogeneity and supporting workflow. The BigPanDA project is underway to setup and tailor PanDA at the Oak Ridge Leadership Computing Facility (OLCF) and at the National Research Center "Kurchatov Institute" together with ALICE distributed computing and ORNL computing professionals. Our approach to integration of HPC platforms at the OLCF and elsewhere is to reuse, as much as possible, existing components of the PanDA system. We will present our current accomplishments with running the PanDA WMS at OLCF and other supercomputers and demonstrate our ability to use PanDA as a portal independent of the computing facilities infrastructure for High Energy and Nuclear Physics as well as other data-intensive science applications.

  8. A proteomic view on the developmental transfer of homologous 30 kDa lipoproteins from peripheral fat body to perivisceral fat body via hemolymph in silkworm, Bombyx mori

    PubMed Central

    2012-01-01

    Background A group of abundant proteins of ~30 kDa is synthesized in silkworm larval peripheral fat body (PPFB) tissues and transported into the open circulatory system (hemolymph) in a time-depended fashion to be eventually stored as granules in the pupal perivisceral fat body (PVFB) tissues for adult development during the non-feeding stage. These proteins have been shown to act anti-apoptotic besides being assigned roles in embryogenesis and defense. However, detailed protein structural information for individual PPFB and PVFB tissues during larval and pupal developmental stages is still missing. Gel electrophoresis and chromatography were used to separate the 30 kDa proteins from both PPFB and PVFB as well as hemolymph total proteomes. Mass spectrometry (MS) was employed to elucidate individual protein sequences. Furthermore, 30 kDa proteins were purified and biochemically characterized. Results One- and two-dimensional gel electrophoresis (1/2D-PAGE) was used to visualize the relative changes of abundance of the 30 kDa proteins in PPFB and PVFB as well as hemolymph from day 1 of V instar larval stage to day 6 of pupal stage. Their concentrations were markedly increased in hemolymph and PVFB up to the first two days of pupal development and these proteins were consumed during development of the adult insect. Typically, three protein bands were observed (~29, 30, 31 kDa) in 1D-PAGE, which were subjected to MS-based protein identification along with spots excised from 2D-gels run for those proteomes. Gas phase fragmentation was used to generate peptide sequence information, which was matched to the available nucleotide data pool of more than ten highly homologous insect 30 kDa lipoproteins. Phylogenetic and similarity analyses of those sequences were performed to assist in the assignment of experimentally identified peptides to known sequences. Lipoproteins LP1 to LP5 and L301/302 could be matched to peptides extracted from all bands suggesting the presence of full length and truncated or modified protein forms in all of them. The individual variants could not be easily separated by classical means of purification such as 2D-PAGE because of their high similarity. They even seemed to aggregate as was indicated by native gel electrophoresis. Multistep chromatographic procedures eventually allowed purification of an LP3-like protein. The protein responded to lipoprotein-specific staining. Conclusions In B. mori larvae and pupae, 30 kDa lipoproteins LP1 to LP5 and L301/302 were detected in PPFB and PVFB tissue as well as in hemolymph. The concentration of these proteins changed progressively during development from their synthesis in PPFB, transport in hemolymph to storage in PVFB. While the 30 kDa proteins could be reproducibly separated in three bands electrophoretically, the exact nature of the individual protein forms present in those bands remained partially ambiguous. The amino acid sequences of all known 30 kDa proteins showed very high homology. High-resolution separation techniques will be necessary before MS and other structural analysis can shed more light on the complexity of the 30 kDa subproteome in B. mori. A first attempt to that end allowed isolation of a B. mori LP3-like protein, the complete structure, properties and function of which will now be elucidated in detail. PMID:22369700

  9. The Hyaluronan Receptor for Endocytosis (HARE) Activates NF-?B-mediated Gene Expression in Response to 40–400-kDa, but Not Smaller or Larger, Hyaluronans*

    The hyaluronan (HA) receptor for endocytosis (HARE; Stabilin-2) binds and clears 14 different ligands, including HA and heparin, via clathrin-mediated endocytosis. HA binding to HARE stimulates ERK1/2 activation (Kyosseva, S. V., Harris, E. N., and Weigel, P. H. (2008) J. Biol. Chem. 283, 15047–15055). To assess a possible HA size dependence for signaling, we tested purified HA fractions of different weight-average molar mass and with narrow size distributions and Select-HATM for stimulation of HARE-mediated gene expression using an NF-?B promoter-driven luciferase reporter system. Human HARE-mediated gene expression was stimulated in a dose-dependent manner with small HA (sHA) >40 kDa and intermediate HA (iHA) <400 kDa. The hyperbolic dose response saturated at 20–50 nm with an apparent Km ?10 nm, identical to the Kd for HA-HARE binding. Activation was not detected with oligomeric HA (oHA), sHA <40 kDa, iHA >400 kDa, or large HA (lHA). Similar responses occurred with rat HARE. Activation by sHA-iHA was blocked by excess nonsignaling sHA, iHA, or lHA, deletion of the HA-binding LINK domain, or HA-blocking antibody. Endogenous NF-?B activation also occurred in the absence of luciferase plasmids, as assessed by degradation of I?B-?. ERK1/2 activation was also HA size-dependent. The results show that HA-HARE interactions stimulate NF-?B-activated gene expression and that HARE senses a narrow size range of HA degradation products. We propose a model in which optimal length HA binds multiple HARE proteins to allow cytoplasmic domain interactions that stimulate intracellular signaling. This HARE signaling system during continuous HA clearance could monitor the homeostasis of tissue biomatrix turnover throughout the body. PMID:23530033

    The solution structures of free Enzyme I (EI, ?128 kDa, 575×2 residues), the first enzyme in the bacterial phosphotransferse system and its complex with HPr (?146 kDa) have been solved using novel methodology that makes use of prior structural knowledge (namely, the structures of the dimeric EIC domain and the isolated EIN domain both free and complexed to HPr), combined with residual dipolar coupling (RDC), small (SAXS) and wide (WAXS) angle X-ray scattering and small angle neutron scattering (SANS) data. The calculational strategy employs conjoined rigid body/torsion/Cartesian simulated annealing, and incorporates improvements in calculating and refining against SAXS/WAXS data that take into account complex molecular shapes in the description of the solvent layer resulting in a better representation of the SAXS/WAXS data. The RDC data orient the symmetrically related EIN domains relative to the C2 symmetry axis of the EIC dimer, while translational, shape and size information is provided by SAXS/WAXS. The resulting structures are independently validated by SANS. Comparison of the structures of the free EI and the EI-HPr complex with that of the crystal structure of a trapped phosphorylated EI intermediate reveals large (?70-90°) hinge body rotations of the two subdomains comprising the EIN domain, as well as of the EIN domain relative to the dimeric EIC domain. These large-scale interdomain motions shed light on the structural transitions that accompany the catalytic cycle of EI. PMID:20731394

    Ectopic thyroid gland may be detected at any place between foramen caecaum and normal thyroid localization due to inadequacy of the embryological migration of the thyroid gland. It has a prevalence varying between 1/10.000 and 1/100000 in the community. Usually follow-up without treatment is preferred except for obstructive symptoms, bleeding, and suspicion of malignity. Main symptoms are dysphagia, dysphonia, bleeding, dyspnea, and obstructive sleep apnea. In symptomatic cases, the first described method in surgical treatment is open approach since it is a region difficult to have access to. However, this approach has an increased risk of morbidity and postoperative complications. Transoral robotic surgery, which is a minimally invasive surgical procedure, has advantages such as larger three-dimensional point of view and ease of manipulation due to robotic instruments. In this report, a case at the age of 49 who presented to our clinic with obstructive symptoms increasing within the last year and was found to have lingual thyroid and underwent excision of ectopic thyroid tissue by da Vinci surgical system is presented.

    In totally endoscopic coronary artery bypass surgery, intra-operative assessment of anastomotic quality is needed. We evaluated the endoscopic application of epicardial ultrasound to visualize the coronary anastomosis and detect a construction error. In 8 pigs (71-78kg), 16 internal mammary artery to left anterior descending coronary artery anastomoses were constructed conventionally, either correctly (n=8) or incorrectly with a suture cross-over construction error (n=8). A 13MHz mini-transducer (15x9x6mm) was introduced through a port and manipulated by the 'da Vinci' system. The chest was re-opened and scanning repeated manually. Postoperatively, macroscopic inspection served as reference and the intra-operative ultrasound images were scored as 'correct' or 'construction error' by two blinded observers. All anastomoses were scored accurately by both observers. One anastomosis constructed to be correct was scored as construction error, due to narrowing of the outflow corner and anastomotic orifice. Ultrasound images corresponded with macroscopic inspection. Closed-chest scan time was about 1.5 times longer than open-chest scan time, 176s (88-464) (median, range) versus 125s (75-314) (P=0.01), respectively. Closed-chest epicardial 13MHz ultrasound scanning required a median of 3min and enabled discrimination between correctly and incorrectly constructed coronary anastomoses. PMID:17670326

    Objectives. Robotic surgery enables to perform coronary surgery totally endoscopically. This report describes our experience using the da Vinci system for coronary artery bypass surgery. Methods. Patients requiring single-or-double vessel revascularization were eligible. The procedure was performed without cardiopulmonary bypass on a beating heart. Results. From April 2004 to May 2008, fifty-six patients were enrolled in the study. Twenty-four patients underwent robotic harvesting of the mammary conduit followed by minimal invasive direct coronary artery bypass (MIDCAB), and twenty-three patients had a totally endoscopic coronary artery bypass (TECAB) grafting. Nine patients (16%) were converted to open techniques. The mean total operating time for TECAB was 372 ± 104 minutes and for MIDCAB was 220 ± 69 minutes. Followup was complete for all patients up to one year. There was one hospital death following MIDCAB and two deaths at follow up. Forty-eight patients had an angiogram or CT scan revealing occlusion or anastomotic stenoses (>50%) in 6 patients. Overall permeability was 92%. Conclusions. Robotic surgery can be performed with promising results. PMID:20339505

    Cystic lesions of the spleen represent a rare entity with an overall incidence of 0.5% among splenectomies. They can remain asymptomatic in 30% to 60% of patients or may cause symptoms for secondary compression of adjacent structures. Peripheral cysts may be suitable for conservative treatment whereas splenectomy is the accepted procedure for bulky and/or central lesions. Laparoscopy is the standard approach for elective splenic surgery, but in the last decade, introduction of the da Vinci robotic system has represented a further improvement in minimally invasive surgery, thanks to 3-dimensional vision and more accurate motion control. Herein, we report a case of a mesothelial splenic cysts successfully treated by robotic splenectomy; some anatomical considerations and technical aspects of robotic procedures have been discussed: it is a feasible and safe approach, particularly indicated in the presence of anatomic features such as an enlarged pancreatic tail and a type II vascular pattern of splenic pedicle. In such patients, the choice of a robotic approach may decrease the risk of intraoperative bleeding, thereby representing a further improvement in laparoscopic techniques. PMID:21471791

    Music is often played in the operating room to increase the surgeon's concentration and to mask noise. It could have a beneficial effect on surgical performance. Ten participants with limited experience with the da Vinci robotic surgical system were recruited to perform two surgical tasks: suture tying and mesh alignment when classical, jazz, hip-hop, and Jamaican music were presented. Kinematics of the instrument tips of the surgical robot and surface electromyography of the subjects were recorded. Results revealed that a significant music effect was found for both tasks with decreased time to task completion (P = .005) and total travel distance (P = .021) as well as reduced muscle activations ( P = .016) and increased median muscle frequency (P = .034). Subjects improved their performance significantly when they listened to either hip-hop or Jamaican music. In conclusion, music with high rhythmicity has a beneficial effect on robotic surgical performance. Musical environment may benefit surgical training and make acquisition of surgical skills more efficient. PMID:20817638
