"Introduction: Cardiac coronary dominance plays a significant role in different clinical conditions and diseases of the heart. As the people of developing and developed nations are having global coronary artery diseases, it is mandatory to have knowledge of coronary artery diseases including cardiac coronary dominance. The aim of this study is to find out the prevalence of the right coronary artery dominance in cadaveric human hearts in a medical college. Methods: A descriptive cross-sectional study was conducted among all 52 preserved hearts as well as the heart isolated from cadavers obtained from the teaching hospital. The study was conducted from 24th June, 2020 to 24th December, 2020 after obtaining ethical clearance from the Institutional Review Committee (Reference number: 2306202004). All cadaveric heart specimens were laelled with numbers and photographed for easy description of anatomical variation related to the coronary artery. Data were entered into Microsoft Excel 2007 and analysed using Statistical Package for the Social Sciences version 20.0. Point estimate at 90% Confidence Interval was calculated along with frequency and proportion for binary data. Results: Out of 52 undissected isolated cadaveric hearts, the right cardiac dominance was found in 42 (80.76%) (71.77-89.75 at 90% Confidence Interval). The mean diameter of the right coronary artery was found to be 4.06±0.55 mm. Conclusions: The prevalence of right cardiac dominance in isolated cadaveric hearts was similar to the studies done in a similar setting. Keywords: cardiac; coronary arteries; dominance."

Background Even if 3D angiographic images of preoperative contrast-enhanced computed tomography (CT) are created, the coronal and axial sections can be unclear, and thus, it is difficult to achieve projection awareness similar to that of actual laparoscopic images. In recent years, the technology of analyzing and applying medical images has advanced, and surgical simulation and navigation have been widely used to improve the safety of surgical operations. It is important to understand pelvic anatomy in the area of rectal cancer, and use of the SYNAPSE VINCENT makes it possible to simulate the anatomy before surgery, which is very useful in educating surgeons and their assistants. Materials and methods An important objective in surgery is to understand the anatomy of the external/internal iliac arteries and lymph nodes in lateral lymph node dissection (LLD) for rectal cancer. In this study, we explored the accuracy and usefulness of SYNAPSE VINCENT images of pelvic anatomy (especially vascular anatomy) analyzed preoperatively in two cases of LLD for rectal cancer in our department. Results The patients were two men aged 73 and 57 years, respectively. Both patients underwent robotic abdominal perineal resection and LLD with neoadjuvant chemoradiotherapy. The operating times for LLD were 138 and 106 min, estimated blood loss was less than 10 mL and 20 mL, and the harvested lymph nodes were nos. 21 and 22, respectively. The SYNAPSE VINCENT could be used for simulation and navigation before and during surgery. For experienced surgeons, the system helped them carry out operations more accurately. Conclusion In the future, surgical support using virtual reality, augmented reality, and mixed reality based on medical images will be useful and is expected to improve the safety, accuracy, and efficiency of surgery, which is extremely useful for both young and skilled surgeons preparing for difficult operations.

The morphometry and morphology of the components of extrahepatic biliary tree show extensive variations. A beforehand recognition of these variations is very crucial to prevent unintended complications while performing surgeries in this region. This study was conducted to analyze the configuration of the extrahepatic biliary tree and its possible variations, as well as measure the components that limit the cystohepatic triangle. Articles were searched in major online indexed databases (Medline and PubMed, Scopus, Embase, CINAHL Plus, Web of Science and Google Scholar) using relevant key words. A total of 73 articles matched the search criteria of which 55 articles were identified for data extraction. The length of left and right hepatic duct in majority of studies was found to be >10 mm. A wide range of diameters of hepatic ducts were observed between 5-43 mm. The average length of cystic duct is around 20 mm. The length and diameter of the common bile duct are 50-150 mm and 3-9 mm respectively. The most frequently observed pattern of insertion of cystic duct into common hepatic duct is right lateral, rarely anterior, or posterior spiral insertion can present. The results of this study will provide a standard reference range which instead will help to differentiate the normal and pathological conditions.

"Background: The arterial anatomy of the face is extremely variable. Despite numerous cadaver dissections and anatomical descriptions, the exact location of the superficial facial arteries remains unpredictable. This ignorance is a determining factor in the pathophysiology of intravascular filler injections, potentially causing skin necrosis and blindness. Objectives: The main objective of this study is to evaluate the accuracy of an augmented reality (AR) application that visualizes the individual arterial anatomy of the face. Methods: A workflow was developed during which a magnetic resonance angiography (MRA) mapped the superficial arteries of the face. The images were further processed into an AR image that was visualized on the patient's face using a specifically designed smartphone application. The accuracy of the AR image and the position of each individual artery were analyzed using duplex ultrasound (US). Results: A total of 216 facial arteries were visualized in 20 patients. The superficial temporal (100%), supratrochlear (92.5%), facial (75%), and angular (82.5%) arteries were visualized the most. The inferior labial (17.5%), dorsal nasal (22.5%), and supraorbital (42.5%) arteries were the most difficult to visualize through MRA. The average deviation between the artery visible on the AR image and the location assessed by US was 0.30 mm (standard deviation = +/- 0.66 mm). There were no complications reported. Conclusions: The combination of a risk-free MRA to map the individual arteries of the face and the processing into an AR image may be considered as a useful and accurate tool during dermal filler injections to potentially minimize the risk of intravascular filler injections."

The discovery of several waterlogged plant remains in a Middle Ages context (1330-1360 AD) in Sassari (NS, Sardinia, Italy) enabled the characterisation of archaeological plum fruit stones and watermelon and grape seeds through computer image analysis. Digital seed/endocarp images were acquired by a flatbed scanner and processed and analysed by applying computerised image analysis techniques. The morphometric data were statistically elaborated using stepwise linear discriminant analysis (LDA), allowing comparisons among archaeological remains, wild populations and autochthonous cultivars. Archaeological samples of plum were compared with 21 autochthonous cultivars of Prunus domestica from Sardinia, while archaeological watermelon seeds were compared with 36 seed lots of Citrullus from Europe, Africa and Asia. Moreover, archaeological grape seeds were compared with 51 autochthonous traditional cultivars of Vitis vinifera subsp. vinifera from Sardinia, 16 cultivars from Tuscany, six cultivars from Liguria, and eight cultivars from Catalonia (Spain). Archaeological plum remains showed morphological affinity with five cultivars of Sardinia. Seed features of the archaeological watermelon remains demonstrated affiliation with a proper sweet dessert watermelon, Citrullus lanatus, and similarity with some Sardinian cultivars. Regarding the archaeological remains of grape, morphometric comparisons showed a high similarity with autochthonous cultivars from Catalonia and Liguria. This study provides new information about ancient fruit cultivated and consumed during the Middle Ages in Sardinia.

This paper is concerned with the role of human institutions as generators of architectural form, with reference to the writings and works of Peter Behrens, Jorn Utzon, and Louis Kahn. In contrast with the narrow functionalist approach promoted by some of their contemporaries, these architects regarded human institutions as living entities that ought to have a determinative influence on the design of the buildings constructed to house them. The paper considers these architects’ assumptions regarding the concept of ‘institution’ within a broad social and political context and offers some suggestions for a more systematic investigation in that respect.The paper begins with a brief outline of functionalist theory, then turns to the theatre as a primary cultural activity and the prominent place it held in Behrens’s thinking during the opening years of the 20th century. Affinities are explored between Behrens’s concept of the theatre and Utzon’s subsequent treatment of the theatre as a central civic institution in his design for the Sydney Opera House. A parallel is seen in Louis Kahn’s insistence that an architectural project should begin with a vision of the human institution which the project is to serve, a perception of their role that was present in utopian and radical schemes from the 19th century onwards. The concluding sections of the paper raise some questions about the doctrines of Behrens, Utzon, and (especially) Kahn, by considering how institutions are adapted to their socio-political settings and how they affect architectural outcomes in practice.

Since it was established that the early hominins of the Cradle of Humankind in South Africa ate 13C-enriched foods that may have included sedges with C4 photosynthetic pathways, much work has focused on the reconstruction of hominin dietary ecologies in both southern and eastern Africa. Through the years emphasis was placed on Cyperus papyrus as a possible source, even inspiring an ‘aquatic diet’ hypothesis for all hominins. Baboon feeding habits and sedge regimes observed in South Africa’s ‘Lowveld’ have provided a proxy for the dietary ecology of the southern ‘Highveld’ hominins, and from the Cradle of Humankind sedges, amongst other plants, have been collected for nutritional studies. To date, however, there has been no attempt to compile an inventory of the sedge species currently growing in the demarcated area of the Cradle of Humankind. Here I list 29 Cyperaceae taxa currently recorded as growing in the Cradle of Humankind. I show that, contrary to previous inference, most of them have C4 photosynthetic pathways and do not need aquatic ecologies or permanent wetland settings. I discuss and provide photographic records for the six species identified as current baboon and human foodplants, and highlight Cyperus esculentus as a possible nutritious and prolific C4-sedge-USO food source for southern African hominins based on its energy, protein and fat/lipid profile.

What role did migration play in the making of modern Britain? We now have a good sense of how ethnicity, class, religion and gender structured immigrants' experience and what impact they had on Britain's culture, society and economy. But as Nancy Green pointed out almost two decades ago, scholars of migration must focus on exit as well as entry. Such a call to study ‘the politics of exit’ is especially apposite in the case of the UK. For in every decade between 1850 and 1980 (with the exception of the 1930s), the UK experienced net emigration year on year. This article analyses this outflow of migrants to reveal a new vision of the UK as an ‘emigration state’. The article employs this concept to make a new argument about the formation of migration policy in the UK and offers a revised account of the geographical boundaries of the modern British state.

Moving ‘out’ to be ‘in’: the suburbanization of London Jewry, 1900–1939

Abstract Between 1900 and 1939, Jewish Londoners departed the East End for the suburbs. Relocation, however, was not always the result of individual agency. Many Jews became the object of institutional strategies to coerce and persuade them to disperse away from inner-city areas. Simultaneous to this was the emergence of a dominant pro-suburban rhetoric within and beyond Jewish cultural circles, which aimed to raise aspirations towards middle-class lifestyles. This striking suburban ‘urge’ amongst London Jewry, managed by the community's elite institutions and leaders, was far more than a phenomenon running parallel to wider British society. As this article argues, it was a decisive response to an insidious culture of intolerance and antisemitism.
