The purpose of this study was to determine the intra and inter-assessor repeatability of a modified Rizzoli Foot Model for analysing the foot kinematics of ballet dancers. Six university-level ballet dancers performed the movements; parallel stance, turnout plié, turnout stance, turnout rise and flex-point-flex. The three-dimensional (3D) position of individual reflective markers and marker triads was used to model the movement of the dancers' tibia, entire foot, hindfoot, midfoot, forefoot and hallux. Intra and inter-assessor reliability demonstrated excellent (ICC ≥ 0...

Tumor resection causes damage in the head and neck which creates problems in swallowing, chewing, articulation, and vision, all of which seriously affect patients' quality of life. In this work, we evaluated the application of a free medial tibial flap in reconstruction of head and neck defects after tumor resection. We discussed the anatomy, surgical technique, and the advantages and disadvantages of the flap. We found several benefits for the flap, such as, it is especially effective for the defects that require thin-layer epithelium to cover or the separated soft tissue defect; a two-team approach can be used because the donor site is far away from the head and neck; and the flap is easy to integrate because of the subcutaneous fat layer of the free medial tibial flap is thin and the flap is soft...

Archaeognatha represent the oldest living lineage of true insects (=Ectognatha), which are remarkable, among others, for plesiomorphic genital morphology and complicated mating behaviour. I used scanning electron microscopy and He-ion microscopy to examine the ovipositor morphology of seven species, in order to describe the cuticle microsculpture. The species studied are characterised by different types of the ovipositor setation pattern, which are considered an important taxonomic feature for Archaeognatha...

The field of laparoscopic surgery has continued to grow exponentially over the years, prompting new innovative technologies. Despite substantial advancements, standard laparoscopic tools have undergone little design changes and fail to optimize mobility in limited spaces. Advancements in robotics have attempted to address this, allowing for increasing degrees of freedom and articulation of instruments. Even so, this system has proven to be cumbersome with questionable cost-effectiveness. In this study, we present the first use of a solely mechanical intuitively controlled articulating laparoscopic needle driver...

An academic health department (AHD) is a formal partnership between an academic institution and a governmental public health agency. Case studies have described the value of individual AHDs in the areas of student engagement, practice-based research, workforce development, and service. With growing interest in AHDs and the increasing importance of academic-practice linkages in both academic programs' and public health agencies' accreditation processes, articulating a research agenda focused on the AHD model can be useful for stimulating the research and practice fields to further develop the evidence base for AHDs...

Michal Icht, Boaz M Ben-David
The Hebrew IPA charts describe the sibilants /s, z/ as 'alveolar fricatives', where the place of articulation on the palate is the alveolar ridge. The point of constriction on the tongue is not defined - apical (tip) or laminal (blade). Usually, speech and language pathologists (SLPs) use the apical placement in Hebrew articulation therapy. Some researchers and SLPs suggested that acceptable /s, z/ could be also produced with the laminal placement (i.e. the tip of the tongue approximating the lower incisors)...

Tim Kasser
Psychobiography, the intense study of a particular person, has long existed at the fringes of mainstream psychology. This special section is comprised of two articles that take important steps to integrate psychobiography into the mainstream of psychology. Schultz and Lawrence (2017) do so by reviewing recent examples of how contemporary psychobiographers have used empirically supported methods and theories to reach conclusions about the individuals under study. Ponterotto and Reynolds (2017) do so by articulating important ethical issues relevant to the practice of psychobiography, a topic on which the American Psychological Association's current ethical code provides little guidance (American Psychological Association, 2017)...

Axial morphology was dramatically transformed during the transition from terrestrial to aquatic environments by archaeocete cetaceans, and again during the subsequent odontocete radiation. Here, we reconstruct the sequence of developmental events that underlie these phenotypic transitions. Archaeocete innovations include the loss of primaxial/abaxial interaction at the sacral/pelvic articulation and the modular dissociation of the fluke from the remainder of the tail. Odontocetes subsequently integrated lumbar, sacral, and anterior caudal vertebrae into a single torso module, and underwent multiple series-specific changes in vertebral count...

A constellation of medical conditions inclusive of central obesity, hyperglycemia, hypertension, and dyslipidemia is known as metabolic syndrome (MetS). The safest option in curtailing the progression of MetS is through maintaining a healthy lifestyle, which by itself, is a long-term commitment entailing much determination. A combination of pharmacological and non-pharmacological approach, as well as lifestyle modification is a more holistic alternative in the management of MetS. Vitamin E has been revealed to possess anti-oxidative, anti-inflammatory, anti-obesity, anti-hyperglycemic, anti-hypertensive and anti-hypercholesterolemic properties...

Home care, one of the services provided by the health system, requires health practitioners who are capable of understanding its specificities. This study aimed to build a substantive theory that describes experiences of home care teaching and learning during undergraduate degree courses in nursing, pharmacy, medicine, nutrition, dentistry and occupational therapy. A qualitative analysis was performed using the grounded theory approach based on the results of 63 semistructured interviews conducted with final year students, professors who taught subjects related to home care, and recent graduates working with home care, all participants in the above courses...

Understanding that conditions of health are dependent on more general nationwide factors relating to the level of development means admitting that 'sectorization' of health service is something that tends to limit the formation of knowledge. It also points to the importance of investigating the relationship between health and development, including issues about the processes that feed the persistence of the polarization between modernization and exclusion which has been a history of Brazil's contemporary development...

Engaging recent social science work examining the truth making claims of science and biomedicine, this paper explores how biology is being localised in Brazilian cancer genetics. It draws from ethnographic fieldwork in urban regions of southern Brazil working with and alongside patients, families and practitioners in cancer genetic clinics. It examines how different sorts of 'local biologies' are articulated in the context of research, clinical practice and among implicated patient communities and the way these can 'recursively' move across different spheres and scales of social action to extend and transform the meaning of the biological...

The basal non-mammaliaform cynodonts from the late Permian (Lopingian) and Early Triassic are a major source of information for the understanding of the evolutionary origin of mammals. Detailed knowledge of their anatomy is critical for understanding the phylogenetic transition toward mammalness and the paleobiological reconstruction of mammalian precursors. Using micro-computed tomography (μCT), we describe the internal morphology of the interorbital region that includes the rarely fossilized orbitosphenoid elements in four basal cynodonts...

S R Beardmore, E Lawlor, D W E Hone
In fossilised vertebrates, the presence of soft tissues is the most obvious way to determine aspects of anatomy and functional morphology; however, occurrences are rare and other lines of evidence must be sought to indicate its extent and strength. For example, pterosaurs possessed a large wing membrane that enabled powered flight but other tissues are not widely preserved. A semi-quantitative analysis comparing skeletal articulation and completeness of the pterodactyloid Pterodactylus and non-pterodactyloid pterosaur Rhamphorhynchus from Solnhofen-type deposits implies there were anatomical differences between soft-tissue structure and attachments articulating skeletal joints of each...

The American military is embarking on the 'Third Offset'-a strategy designed to produce seismic shifts in the future of warfare. Central to the approach is the conjoining of humans, technology, and machines to deliver a decisive advantage on the battlefield. Because technology will spread rapidly and globally, tactical overmatch will occur when American operators possess a competitive edge in cognition. Investigation of cognitive enhancing therapeutics is not widely articulated as an adjunct to the Third Offset, yet failure to study promising agents could represent a strategic vulnerability...

BACKGROUND: Injury or loss of the meniscus generally leads to degenerative osteoarthritic changes in the knee joint. However, the treatment options for symptomatic patients with total meniscectomy are limited. Therefore, we developed a novel, anatomically shaped, total meniscal implant made of polycarbonate urethane. PURPOSE: To evaluate the in vivo performance of this novel total meniscal implant. The assessment particularly focused on the implant's response to long-term physiological loading in a goat model and its chondroprotective capacity in comparison to clinically relevant controls...

Peri-prosthetic joint infection remains one of the most difficult and challenging complications following hip and knee arthroplasty for both patients and surgeons. Two-stage revision arthroplasty for infection remains the most popular option for the majority of patients and arguably the only option for some. The use antibiotic spacers and in particular articulating spacers has improved the quality of life for patients between stages. The spacers provides local delivery of high concentration antibiotics and provides many benefits to the soft tissues including maintaining soft tissue tension and range of movement...
