Abstract
In minimally invasive surgery, a higher degree of accuracy is required by surgeons both for current and for future applications. This could be achieved using either a manipulator or a robot which would undertake selected tasks during surgery. However, a manually-controlled manipulator cannot fully exploit the maximum accuracy and feasibility of three-dimensional motion sequences. Therefore, apart from being used to perform simple positioning tasks, manipulators will probably be replaced by robot systems more and more in the future. However, in order to use a robot, accurate, up-to-date and extensive data is required which cannot yet be acquired by typical sensors such as CT, MRI, US or common x-ray machines. This paper deals with a new sensor and a concept for its application in robot-assisted minimally invasive surgery on soft tissue which could be a solution for data acquisition in future.

Abstract
There is an increasing necessity for surgeons and engineers to work together in order to target future technological developments at clinical need and cost-effectiveness. This is a report of two linked meetings with these objectives, held at the Institute of Mechanical Engineers, London, UK. The two meetings were organized by the same faculty members and held on consecutive days. Delegates included surgeons, academic mechanical engineers, researchers and industrial representatives. The programme was made up of varied presentations by surgeons and engineers as well as open discussion of the topics covered. Delegates were updated on the current state of surgical robotics in the UK in four surgical specialties; urology, neurosurgery, orthopaedics and ENT. This included clinical and experimental evidence, together with discussion of future advances. Minimally invasive surgery, real-time imaging and the development of more compact and cost effective surgical robots were identified as key areas for future research.

Abstract
PURPOSE OF REVIEW The use of robotics in urologic surgery has seen exponential growth over the last 5 years. Existing surgical robots operate rigid instruments on the master/slave principle and currently allow extraluminal manipulations and surgical procedures. Flexible robotics is an entirely novel paradigm. This article explores the potential of flexible robotic platforms that could permit endoluminal and transluminal surgery in the future. RECENT FINDINGS Computerized catheter-control systems are being developed primarily for cardiac applications. This development is driven by the need for precise positioning and manipulation of the catheter tip in the three-dimensional cardiovascular space. Such systems employ either remote navigation in a magnetic field or a computer-controlled electromechanical flexible robotic system. We have adapted this robotic system for flexible ureteropyeloscopy and have to date completed the initial porcine studies. SUMMARY Flexible robotics is on the horizon. It has potential for improved scope-tip precision, superior operative ergonomics, and reduced occupational radiation exposure. In the near future, in urology, we believe that it holds promise for endoluminal therapeutic ureterorenoscopy. Looking further ahead, within the next 3-5 years, it could enable transluminal surgery.

Abstract
Social intelligence in robots has a quite recent history in artificial intelligence and robotics. However, it has become increasingly apparent that social and interactive skills are necessary requirements in many application areas and contexts where robots need to interact and collaborate with other robots or humans. Research on human-robot interaction (HRI) poses many challenges regarding the nature of interactivity and 'social behaviour' in robot and humans. The first part of this paper addresses dimensions of HRI, discussing requirements on social skills for robots and introducing the conceptual space of HRI studies. In order to illustrate these concepts, two examples of HRI research are presented. First, research is surveyed which investigates the development of a cognitive robot companion. The aim of this work is to develop social rules for robot behaviour (a 'robotiquette') that is comfortable and acceptable to humans. Second, robots are discussed as possible educational or therapeutic toys for children with autism. The concept of interactive emergence in human-child interactions is highlighted. Different types of play among children are discussed in the light of their potential investigation in human-robot experiments. The paper concludes by examining different paradigms regarding 'social relationships' of robots and people interacting with them.

Abstract
In the development of high throughput screening (HTS) as a central paradigm of drug discovery, fluorescence has generally been adopted as the favored methodology. Nevertheless, luminescence has maintained a prominent position among certain assay formats, most notably genetic reporters. Recently, there has been growing partiality for luminescent assays across a wider range of applications due to their sensitivity, broad linearity, and robustness to library compounds and complex biological samples. This trend has been fostered by the development of several new assay designs for diverse targets such as kinases, cytochrome p450s, proteases, apoptosis, and cytotoxicity. This review addresses recent progress made in the use of bioluminescent assays for HTS, highlighting new detection capabilities brought about by engineering luciferase genes, enzymes, and substrates. In genetic reporter applications, modifications to the luciferase genes have improved assay sensitivity by substantially increasing expression efficiency and enhanced response dynamics by reducing expression lifetime. The performance of assays based on detection of ATP and luciferin has been enhanced by modifications to the luciferase enzyme that increase its chemical and physical stability. Detection of ATP allows rapid analysis of cell metabolism and enzymatic processes coupled to ATP metabolism. Because luciferins are not naturally associated with mammalian physiology, assays for luciferin detection utilize synthetic derivatives designed to yield luminescence only when coupled with specific target enzymes. Finally, new methods for modulating the specific activity of luciferases are leading to the development of intracellular biosensors for dynamic detection of physiological processes.

Abstract
Perfect storms abound in nursing and healthcare. How we plan for them and how we forecast effectively which ones will have tremendous impact on how we lead the profession is a challenge to anyone who is or will be a leader. This article focuses on key forecasts that contribute to creating perfect storms of the future. The "perfect storm" is a term found in multiple disciplines. The phrase denotes the condition that exists when events occur simultaneously with the result that this confluence has a greater impact than what could have resulted from a chance combination. Although perfect storms are rare, they have enormous impact when they occur, and if an alteration in any of the events occurs, the overall impact is lessened.

Abstract
OBJECTIVES To describe 2 new ways of assessing and inducing neuroplasticity in the human brain--transcranial magnetic stimulation (TMS) and robotics--and to investigate and promote the recovery of motor function after brain damage. DATA SOURCES We identified recent articles and books directly bearing on TMS and robotics. Articles using these tools for purposes other than rehabilitation were excluded. From these studies, we emphasize the methodologic and technical details of these tools as applicable for assessing and inducing plasticity. STUDY SELECTION Because both tools have only recently been used for rehabilitation, the majority of the articles selected for this review have been published only within the last 10 years. DATA EXTRACTION We used the PubMed and Compendex databases to find relevant peer-reviewed studies for this review. The studies were required to be relevant to rehabilitation and to use TMS or robotics methodologies. Guidelines were applied via independent extraction by multiple observers. DATA SYNTHESIS Despite the limited amount of research using these procedures for assessing and inducing neuroplasticity, there is growing evidence that both TMS and robotics can be very effective, inexpensive, and convenient ways for assessing and inducing rehabilitation. Although TMS has primarily been used as an assessment tool for motor function, an increasing number of studies are using TMS as a tool to directly induce plasticity and improve motor function. Similarly, robotic devices have been used for rehabilitation because of their suitability for delivery of highly repeatable training. New directions in robotics-assisted rehabilitation are taking advantage of novel measurements that can be acquired via the devices, enabling unique methods of assessment of motor recovery. CONCLUSIONS As refinements in technology and advances in our knowledge continue, TMS and robotics should play an increasing role in assessing and promoting the recovery of function. Ongoing and future studies combining TMS and robotics within the same populations may prove fruitful for a more detailed and comprehensive assessment of the central and peripheral changes in the nervous system during precisely induced recovery.

Abstract
This paper reports our progress in developing techniques for "parsing" raw motion data from a simple surgical task into a labeled sequence of surgical gestures. The ability to automatically detect and segment surgical motion can be useful in evaluating surgical skill, providing surgical training feedback, or documenting essential aspects of a procedure. If processed online, the information can be used to provide context-specific information or motion enhancements to the surgeon. However, in every case, the key step is to relate recorded motion data to a model of the procedure being performed. Robotic surgical systems such as the da Vinci system from Intuitive Surgical provide a rich source of motion and video data from surgical procedures. The application programming interface (API) of the da Vinci outputs 192 kinematics values at 10 Hz. Through a series of feature-processing steps, tailored to this task, the highly redundant features are projected to a compact and discriminative space. The resulting classifier is simple and effective.Cross-validation experiments show that the proposed approach can achieve accuracies higher than 90% when segmenting gestures in a 4-throw suturing task, for both expert and intermediate surgeons. These preliminary results suggest that gesture-specific features can be extracted to provide highly accurate surgical skill evaluation.

Abstract
Cancer is the leading cause of death in the United States among people younger than 85 years, and for the first time has surpassed heart disease as the number one killer. This worrisome statistic has resulted not from an increase in the incidence of cancer, but because deaths from heart disease have dropped nearly in half while the number of cancer-related deaths has remained about the same. This fact accentuates the need for a new generation of more effective therapies for cancer. In this review, the development of new therapies will be discussed in the context of advances in nanotechnologies related to cancer detection, analysis, diagnosis, and therapeutic intervention. First, several nanoanalytical methods, such as the use of quantum dots in detection and imaging of cancer, will be described. These techniques will be essential to the process of precisely describing cancer at the level of the cell and whole organism. Second, examples of how nanotechnologies can be used in the development of new therapies will be given, including methods that might allow for more efficient and accurate drug delivery and rationally designed, targeted drugs. Finally, a new initiative--the National Cancer Institute Alliance for Nanotechnology in Cancer--will be described and discussed with respect to the scientific issues, policies, and funding.

Abstract
If all the signs are to be believed, then the twenty-first century will technologically be characterized by machine walking and its relevant products, which possess all chances to become real bulk goods in the course of the next decades. With several university institutes and with Honda and Sony from the industrial side, Japan is today and without any doubt the leading nation in research and development of walking machines. The US and Europe follow at some distance. Walking machines will influence all areas of daily and industrial life and, with the fast evolution of artificial intelligence, will become a real partner of human beings. All relevant technologies are highly interdisciplinary, they will push the future technologies of all technical fields. The special issue on this topic gives a selection of walking machine research and development including some aspects from biology.

Abstract
Honda has been doing research on robotics since 1986 with a focus upon bipedal walking technology. The research started with straight and static walking of the first prototype two-legged robot. Now, the continuous transition from walking in a straight line to making a turn has been achieved with the latest humanoid robot ASIMO. ASIMO is the most advanced robot of Honda so far in the mechanism and the control system. ASIMO's configuration allows it to operate freely in the human living space. It could be of practical help to humans with its ability of five-finger arms as well as its walking function. The target of further development of ASIMO is to develop a robot to improve life in human society. Much development work will be continued both mechanically and electronically, staying true to Honda's 'challenging spirit'.

Abstract
The rapid expansion of the field of minimally invasive surgery has been accompanied by a number of controversies. These novel surgical techniques offer benefits to the patient with regard to length of hospital stay, return to full activity, and cosmesis; also, they are often more cost-effective than open procedures. On the other hand, they are technically demanding, have a significant learning curve, and can be associated with high initial complication rates unless performed by experienced endoscopic surgeons. Telemedicine, which uses real-time video and information transfer, offers the potential to increase the availability of minimally invasive surgery through video-assisted surgery and through remote instruction. At present, remote communities, especially those within developed countries, can most immediately benefit from telesurgical approaches. Enthusiasm must be tempered by the issues of cost, security, surgeon liability and availability of the technology itself which have yet to be fully resolved. In this Review, the field of telemedicine, focusing specifically on telementoring and telesurgery, and its relevance to urology are discussed. From early experimental work to current clinical usage, the advantages of and problems in this evolving field are explored.

Abstract
BACKGROUND Over the last decade minimally invasive endourologic and laparoscopic techniques have become the first line therapies for primary UPJ obstruction. Robotic assisted laparoscopic pyeloplasty for the correction of ureteropelvic junction has achieved outcomes comparable to those of open and laparoscopic techniques. We present a comprehensive review of the current literature of robotic assisted pyeloplasty. METHODS We performed a systemic review of all the current literature examining demographic data, intra operative parameters and post-operative outcomes. RESULTS In most published series in the literature, the operative time ranges from 122 to 300 minutes and the operative time ranges from 27 to 77 ml. Most series considers subjective improvement in the symptoms and improved drainage on post-operative diuretic renal scan as the measures of success. The reported success rates vary from 89 to 100%. CONCLUSION Robotic pyeloplasty is a feasible alternative to laparoscopic pyeloplasty. Short-term results indicate equivalent outcomes with the laparoscopic procedure. Long-term studies are still needed to compare robotic and open pyeloplasty outcomes, and to define the role of robotic pyeloplasty in a cost prohibitive health care system.

Abstract
BACKGROUND In the past 20 years, the technical aspects of abdominal surgery have changed dramatically. Operations are now routinely performed by laparoscopic techniques utilizing small abdominal incisions, with less patient discomfort, earlier recovery, improved cosmesis, and in many cases reduced economic burden on the healthcare provider. These benefits have largely been seen in the application of laparoscopic techniques to relatively straightforward procedures. It is not clear whether the same benefits carry through to more complex abdominal operations, which are more technically demanding and for which current laparoscopic instrumentation is less well adapted. The aim of surgical robotics is to address these problems and allow the advantages of minimal access surgery to be seen in a greater range of operations. METHODS A literature search was performed to ascertain the current state of the art in surgical robotics for the abdomen, and the technologies emerging within this field. The reference lists of the sourced articles were also searched for further relevant papers. RESULTS Currently available robotic devices for abdominal surgery are limited to large, costly 'slave-master' or telemanipulator systems, such as the da Vinci (Intuitive Surgical, Sunny Vale, CA). In addition to their size and expense, these systems share the same limitation, by virtue of the fulcrum effect on instrument manipulation inherent in the use of ports by which external instruments gain access to the abdominal cavity. In order to overcome these limitations several smaller telemanipulator systems are being developed, and progress towards freely mobile intracorporeal devices is being made. CONCLUSIONS While current robotic systems have considerable advantages over conventional laparoscopic techniques, they are not without limitations. Miniaturisation of robotic components and systems is feasible and necessary to allow minimally invasive techniques to reach full potential. The ultimate extrapolation of this progress is the development of intracorporeal robotics, the feasibility of which has been demonstrated.
