Surgery in space requires enhancing the user's skills under the expert physician's remote guidance. Therefore, the Surgical Engineering Society, with Bioastronautics and Space Mechatronics Research Group have worked on a collaborative study from 2020 to 2021, resulting in the proposed project named "SP-LAP" which is a Medical Robot, defined as a Surgical Laparoscopic Simulation Platform integrated with multi-degree-of-freedom (multi-DOF) system. The analysis is focused on the mechanical design, telemedicine assistance, surgical training and human factors, considering aerospace engineering fundamentals. It has been chosen to evaluate the surgical performance and to develop the technical-clinical validation tests at Mars Analog Desert.

Surgical robotics is the new age of minimally invasive procedures, for this reason, it is important to acquire fundamental skills using training and simulation. Therefore, a research study was developed to present the design of 2 robotic arms, which are used into SP-LAP training platform for remote control haptic manipulation in order to magnify natural eye-hand-instrument alignment, boost motor dexterity and minimally invasive, enhance ergonomics, ensure feasibility, safety, and patient risk reduction. The proposed medical robotic manipulator has 3 degrees of freedom (DOF), 4 links and 3 joints, which have 9 DOF in combination with the multi-DOF system, to promote the application for new surgical techniques and approaches, based on the ergonomics during triangulation. In conclusion, the analysis is focused on mechanical 3D design and kinematics. The next step of the project is to evaluate adding 2 DOF more, and also work on the mechatronic integration of sensors and actuators, and then, perform test and validation of the cyber-physical system.

Automatic identification of a person's individuality is an important issue today. Brain Computer Interfaces (BCI) which uses EEG as a modality is a promising area for cognitive biometrics. A BCI system could be used to recognise a sequence (say letters, colours or images) by the user. This sequence could form a 'BrainWord', which could be used for authentication in a multimodal environment with other technologies for high security applications. In this work, we studied several variations of the well-known P300 BCI paradigm. The influence of irrelevant stimuli during a task was studied by considering the popular Rapid Serial Visual Paradigm (RSVP). The variation in spatial locations of the presentation stimuli during a task was studied, by designing a Spatially Varying Paradigm. Comparison of classification accuracies and bit rates for eight participants from a BCI perspective, highlights that RSVP paradigm could be exploited effectively for biometrics.

Integrating entrepreneurial thinking into engineering education is a growing area of interest. Existing programs have created content for courses offered during the normal semester where traditional modes of assessment, such as grading, have been used to evaluate learning. Within this research the authors explore another style of offering entrepreneurship and design within engineering education. The authors present their findings and experience in offering designbased immersive learning experiences that are outside of the traditional classroom setting. This paper evaluates whether students involved in the designbased immersive learning experiences developed knowledge pertaining to design and entrepreneurship as evidenced through comparative analysis of student reflections and authoritative literature in the subject area.

THE occasion of this meeting of the Boston Surgical Society is for the presentation of the Henry Jacob Bigelow Gold Medal. Tradition and custom, however, have decreed that some scientific contribution shall be made at every meeting of the Society. In consequence, the distinguished surgeon who will receive the Bigelow Medal, Dr. Frank H. Lahey, has been asked to present a paper. We are fortunate in that he has chosen thyroid surgery as his subject. He is well known to all in this audience and needs no further introduction. I have the honor of presenting Dr. Frank H.

THE AIM OF THE STUDY: Is evaluating the possibility of integrating ICG-fluorescent cholangiography into the general safety system for laparoscopic cholecystectomy to prevent damage to the extrahepatic bile ducts by working out the methodological aspects of navigation technologies. MATERIALS AND METHODS: The analysis of literature data on various approaches to improve the perioperative identification of anatomical structures during laparoscopic cholecystectomy, including the ICG-fluorescent cholangiography, was carried out. This program was implemented during the provision of elective surgical care to 24 patients with cholelithiasis who underwent laparoscopic cholecystectomy with ICG-fluorescent navigation. RESULTS AND DISCUSSION: The developed program included: preoperative assessment of the anatomy of the biliary tree using MRCP; intraoperative technique of safe laparoscopic cholecystectomy with mandatory application of the concept of «critical view of safety» (CVS), which allows the most effective identification of the necessary anatomical structures; the use of ICG-fluorescent cholangiography, which allows to improve the control of anatomical structures at all stages of the operations. CONCLUSIONS: The first experience of using ICG-fluorescent cholangiography testifies to the high informative value of the method, the possibility and prospects of integrating the technology into a comprehensive safety system during laparoscopic cholecystectomy.

<h3>VARIETIES OF ILEUS.</h3> The medical writers of classical antiquity, beginning with Hippocrates, applied the term ileus to pathologic conditions in the abdomen characterized by meteorism, pain, vomiting of bilious feculent matter and interference with the passage of feces and flatus. The essential cause was believed to be inflammation of the intestine or of the peritoneum and<i>"ex inflammatione resiccatur intestinum et constipatur ut neque flatum neque alimenta transmuttat. Venter durus fit et vomit interdum imprimis quidum pituitosa deinde vero biliosa, tandem etiam stercus."</i>¹According to Galen, inflammation produces a cessation of peristalsis, absolute constipation, or antiperistalsis with vomiting of fecal matter, or in brief, the disease called ileus. All through the middle ages the influence of the teaching of Hippocrates and Galen remained dominant. With the development of the anatomic school in the fifteenth and sixteenth centuries and the more careful postmortem examinations, varying anatomic conditions were recognized as the

an important purpose in the life of a professional organization such as the Biomedical Engineering Society.BMES journals offer a venue for novel research to be vetted and reviewed by respected biomedical engineers who frequently hold positions of significance in industry or academia.This rigorous process of peer-review in a BMES journal is an oft-sought mark of support for those engineers seeking promotion, advancement or recognition amongst their peers.While numbers of citations of a published article remain the greatest recognition of scholarly work, there is growing interest in article-based metrics such as ''numbers of downloads'' for a specific article, recognition as the ''most highly downloaded paper'' in a specified period, or post-publication reviews and commentary.Springer, the publisher for all BMES journals, currently lists the number of electronic downloads for the five most heavily downloaded articles summed over a 7, 30 or 90 day period (go to www.springer.comand search for Journal name of interest).This is not only a useful measure of real-time demand for material in all BMES journals, but also an increasingly important measure of interest in individual research articles.This metric helps editors to identify hot topic areas and shifting foci and also helps BME departments to highlight and identify exciting work coming from their institutions.

Polyelectrolyte multilayer (PEM) particles fabricated using the layer-by-layer (LbL) method provides the advantage of being highly customizable despite its simple assembly process. An array of sizes and materials can be selected for the particle template and polyelectrolyte multilayer to tailor for its anticipated purpose. Substances can be encapsulated within the core, in between the multilayer or coated on the outermost surface to provide added functionality of the resultant PEM particles. Biopolymers which are biocompatible and biodegradable are beneficial in biomedical applications of PEM particles such as carrier systems, bioreactors, biosensors, etc. The focus of this project is to bridge the gap between biomedical applications of PEM particles and delivery of active biomacromolecules through the systematic design and development of biodegradable PEM particles for nucleic acid delivery in a biological environment. Encapsulation of reporter plasmid DNA and siRNA within bio-relevant PEM particles (including PEM nanoparticles, microparticles and microcapsules) was explored as well as the interaction of these nucleic acid loaded PEM particles with HEK293T, FibroGRO and HTF cells. Furthermore, cytotoxic studies of the PEM particles were executed to determine the threshold levels for cellular applications. The long term goal is to develop the PEM particles as multifunctional tailor-made biodegradable drug carrier systems with controlled drug release and additional functionalities.

Abstract Background Across sub-Saharan Africa, there is a growing burden of vascular disease amidst inadequate training opportunities. In Kenya, most vascular care is delivered by Cardiothoracic, General and Orthopaedic surgeons with limited specialist vascular training. We aim to build capacity to recognise, assess, and manage patients with foot sepsis, and limb- or life-threatening vascular disease through structured fundamentals and advanced vascular skills training courses. Methods The inaugural Fundamentals course was held in September 2024, followed in September 2025 by Advanced Skills alongside the second Fundamentals course. Structured surveys were administered to participants in both years, with a 1-year follow-up survey distributed to the 2024 cohort to assess application of skills and longer-term impact. Results 56 participants were trained across the 3 courses, with all courses oversubscribed. Faculty numbers increased through a faculty development scheme alongside new regional trainers from Ethiopia and South Africa. All participants rated the courses as relevant to their practice and would recommend them to colleagues. At one-year follow-up, all respondents reported improved ability to assess and manage urgent vascular presentations, and to perform fasciotomies, minor, and major amputations. 91% had referred patients to a vascular surgeon; 27% attended the 2025 Advanced course, with the remainder planning to do so in the future. Conclusions The programme has demonstrated sustained engagement, faculty growth, and oversubscription, underscoring unmet training needs. In collaboration with SSK, COSECSA, and RCS Ed, these courses show potential to strengthen regional capacity in vascular surgery, with Kenya emerging as a training hub.

Come this way, honored Odysseus, great glory of the Achaians, and stay your ship, so that you can listen here to our singing; for no one else has ever sailed past this place in his black ship until he has listened to the honey-sweet voice that issues from our lips; then goes on, well-pleased, knowing more than ever he did; for we know everything that the Argives and Trojans did and suffered in wide Troy through the gods' despite.

THIS evening we meet to do honor to one of our own. Elliott Carr Cutler received his degree in 1913 from Harvard Medical School, where he was a member of the Boylston Medical Society, Alpha Omega Alpha Society and the Aesculapian Club. Thus, characteristically, at the start of his medical career he was a member of the school's literary society, its honor society and its social society. After graduation he went to the Peter Bent Brigham Hospital as surgical house officer. Before the United States entered World War I he was a member of the Harvard Unit, serving with the . . .
