From the Egyptian Book of the Dead to the doctrine of the Greek philosopher Aristotle, ancient secular and religious cultures throughout the world often considered the heart — and not the brain — to be the home of the emotions, cognition and even the soul. Brandt and Huppert reflect on the reasons behind this belief.

Urbanization is one of the most important settlement shifts in human history and has been the focus of research within bioarchaeology for decades. However, there have been limited attempts to synthesize the results of these studies in order to gain a broader perspective on whether or how urbanization affects the biology, demography, and behavior of humans, and how these potential effects are embodied in the human skeleton. This paper outlines how bioarchaeology is well-suited to examine urbanization in the past, and we provide an overview and examples of three main ways in which urbanization is studied in bioarchaeological research: comparison of (often contemporaneous) urban and rural sites, synchronic studies of the variation that exists within and between urban sites, and investigations of changes that occur within urban sites over time. Studies of urbanization, both within bioarchaeology and in other fields of study, face a number of limitations, including a lack of a consensus regarding what urban and urbanization mean, the assumed dichotomous nature of urban versus rural settlements, the supposition that urbanization is universally bad for people, and the assumption (at least in practice) of homogeneity within urban and rural populations. Bioarchaeologists can address these limitations by utilizing a wide array of data and methods, and the studies described here collectively demonstrate the complex, nuanced, and highly variable effects of urbanization.

Before the 20(th) century many deaths in England, and most likely a majority, were caused by infectious diseases. The focus here is on the biggest killers, plague, typhus, smallpox, tuberculosis, cholera, typhoid, dysentery, childhood infections, pneumonia, and influenza. Many other infectious diseases including puerperal fever, relapsing fever, malaria, syphilis, meningitis, tetanus and gangrene caused thousands of deaths. This review of preventive measures, public health interventions and changes in behavior that reduced the risk of severe infections puts the response to recent epidemic challenges in historical perspective. Two new respiratory viruses have recently caused pandemics: an H1N1 influenza virus genetically related to pig viruses, and a bat-derived coronavirus causing COVID-19. Studies of infectious diseases emerging in human populations in recent decades indicate that the majority were zoonotic, and many of the causal pathogens had a wildlife origin. As hunter-gatherers, humans contracted pathogens from other species, and then from domesticated animals and rodents when they began to live in settled communities based on agriculture. In the modern world of large inter-connected urban populations and rapid transport, the risk of global transmission of new infectious diseases is high. Past and recent experience indicates that surveillance, prevention and control of infectious diseases are critical for global health. Effective interventions are required to control activities that risk dangerous pathogens transferring to humans from wild animals and those reared for food.

In this article I trace a history of the most ubiquitous visual symbol of madness: the staff. First, I argue that the staff, in its variants (such as the pinwheel) and with its attachments (such as an inflated bladder), represents madness as air. It thus represents madness as an invisible entity that must be made visible. Secondly, I claim that the staff – being iconic of other ‘unwanted’ categories such as vagabonds – represents the insane as outsiders. Also in this case, the staff serves the purpose of making madness visible. Through this interpretation I show that the urge to make madness visible outlives icons of insanity such as the staff, making it a constant presence in popular culture and medical practice.

Ginseng started to emerge as an international medicinal material during the Joseon Dynasty. This paper examines ginseng as a tribute presented to the Ming royal family by Joseon Dynasty. Joseon Dynasty presented peeled and dried ginseng (white ginseng) to the emperor. The Ming Dynasty demanded chosam (natural ginseng) with no peeling in 1602. By the request of Joseon Dynasty during the period of Lord Gwanghae, the presented ginseng was again changed to pasam (boiled and dried ginseng). Although Nurhachi of the Jurchen (女眞) is known to have invented this method of processing pasam, Joseon was exporting pasam to the Ming Dynasty earlier than that. As such, the Nurhachi theory of the invention of the pasam should be reexamined. Joseon Dynasty presented ginseng to each emperor and heir to the throne through its envoys. The total amount of ginseng sent to the royal family of the Ming Dynasty during the Joseon Dynasty is estimated to be approximately 664 to 880 geuns (斤) per year in the fifteenth century, 300 to 500 geuns in the sixteenth century, and about 160 to 360 geuns in the 17th century. When the Japanese Invasion of Korea occurred in 1592, the Joseon government informed the Ming Dynasty of the miserable situation of the Joseon people and chose to reduce the tribute. However, even after the war, the amount of tribute ginseng in Joseon continued to be small. This is because the medical industry in the Ming Dynasty grew significantly, and medical books prescribing Joseon ginseng increased, and the rich people of the Ming Dynasty loved ginseng so much that they imported Joseon ginseng at high prices. Local residents of Guangdong, China, a major customer base of Joseon ginseng, also used ginseng as a preventive medicine for JangGi. From the fifteenth to the seventeenth centuries, the amount of ginseng that Joseon tributed to the Ming Dynasty continued to decrease, and the ginseng processing method also moved in the direction of reducing the burden of processing. This was caused by changes in the environment surrounding the use of ginseng, including changes in the international situation at the time, growth of the medical industry, increasing interest in ginseng by the people of the Ming, and economic considerations of the Joseon government. The two countries sought changes in the ginseng tribute through an agreement.

In the time of the Renaissance, a major aspect of vision science was understanding how spatial information projected to the viewpoint of the observer, that is, visual perspective, which is one of the primary cues to depth perception. Perspective representation was thus an early form of virtual reality. Although accurate perspective representation was developed earlier in the 15th century, the first analytic perspective scheme was developed by Piero della Francesca, whose chef d’oeuvre is in the Church of San Francesco, Arezzo, in which the present lecture took place. The focus of the lecture was to evaluate some of the contributions of Piero della Francesca and his 15th-century contemporaries to the visual science, art and symbolism of his era, and its significance for the perception of depth structure from two-dimensional images.

This historical surgical retrospection focuses on the temporal de-escalation axillary surgery, focusing on the unceasing efforts of researchers toward new challenges, as documented by extensive studies and trials. Axillary surgery has evolved, aiming to offer the best oncologic treatment and improve the quality of life of women. Axillary lymph-node dissection (ALND) has been replaced by sentinel lymph-node biopsy (SLNB) in women with early clinically node-negative breast cancer, providing adequate axillary nodal staging information with minimal morbidity, and becoming the standard of care in the management of breast cancer. However, this is only the beginning. Strategies in defining systemic and radiotherapeutic treatments have gradually been optimized, offering increasingly refined and targeted breast cancer treatment tools. In recent years, the paradigm of completion ALND after a positive SLNB has been questioned, and several studies have led to revolutionary changes in clinical practice. Moreover, the increasingly pivotal role played by neoadjuvant chemotherapy (NAC) has had a profound effect on the extent of axillary surgery, paving the way to a more finite "targeted" procedure in women with node-positive breast cancer who convert to negative nodes clinically after NAC. The utility of SLNB itself and its subsequent omission in women with negative nodes clinically and breast conservative surgery is also under scientific evaluation. The changes over time in the surgical approach to breast cancer have been numerous and significant. The novel emerging perspective characterized by recent advances in biology and genetics, in dedicated axillary ultrasound imaging and chemotherapy regimens, is the present reality that points to the future of axillary node treatment in breast cancer.

Purpose The Primavera is considered amongst the greatest and controversial artistic masterpieces worldwide painted by renaissance artist Sandro Botticelli. The aim was to identify any underlying medical foundations for the painting. Methods Observational study. Results The painting reveals, a ‘butterfly’ malar rash, bilateral ptosis and a clear neck swelling consistent with a goitre in the figure of Flora. This could be explained by concomitant Graves’ disease and systemic lupus erythematosus, or other presentations of multiple autoimmune syndrome. Conclusion These findings highlight the likely presentation of the earliest pictorial depictions of thyroid disease with systemic lupus erythematosus and emphasize the exactitude of depiction demonstrated by Botticelli in renaissance era.

Oak wood was highly appreciated and widely used for construction in past centuries. As population sizes expanded in some regions of Europe, local forests were depleted of high-quality timber. Therefore, regions of soaring economies were importing timber initially from the European market and eventually from other continents. Origin of archaeological or historical timber is usually identified by means of dendroprovenancing, i.e. statistical matching of tree-ring-width (TRW) series of timber of unknown origin with TRW reference datasets. However, this method has pitfalls and limitations and therefore alternative techniques are needed. Here, we used three different DNA analysis methods to investigate the potential of using ancient (a)DNA, extracted from oak timber derived from historical buildings and shipwrecks from a variety of countries. All the material had also been analysed dendrochronologically, so its dating and provenance is demonstrated. We included heartwood samples in this analysis, for which DNA extraction is especially challenging as it contains chemicals that inhibit DNA amplification. We succeeded in amplifying DNA for at least one marker from 56% of samples (including heartwood samples), yielding crucial information that allowed us to identify the potential source area of centuries old timber buildings in Latvia and Denmark and of 750-year-old shipwreck material from Germany. Our results prove the strong potential of DNA analyses for identifying timber origin to the regional scale, but by combining these with the dendrochronological results, we can control the exactitude of the aDNA approach and demonstrate a more nuanced examination of the timber sources for these historic structures.

OrbiSIMS is a recently developed instrument for label‐free imaging of chemicals with micron spatial resolution and high mass resolution. We report a cryogenic workflow for OrbiSIMS (Cryo‐OrbiSIMS) that improves chemical detection of lipids and other biomolecules in tissues. Cryo‐OrbiSIMS boosts ionization yield and decreases ion‐beam induced fragmentation, greatly improving the detection of biomolecules such as triacylglycerides. It also increases chemical coverage to include molecules with intermediate or high vapor pressures, such as free fatty acids and semi‐volatile organic compounds (SVOCs). We find that Cryo‐OrbiSIMS reveals the hitherto unknown localization patterns of SVOCs with high spatial and chemical resolution in diverse plant, animal, and human tissues. We also show that Cryo‐OrbiSIMS can be combined with genetic analysis to identify enzymes regulating SVOC metabolism. Cryo‐OrbiSIMS is applicable to high resolution imaging of a wide variety of non‐volatile and semi‐volatile molecules across many areas of biomedicine., Cryogenic OrbiSIMS decreases molecular fragmentation and expands the chemical space that is amenable to mass spectrometry imaging with high spatial and mass resolution. Semi‐volatile and non‐volatile molecules can now be imaged simultaneously in biological tissues.

The betaretrovirus Mouse Mammary Tumor Virus (MMTV) is the well characterized etiological agent of mammary tumors in mice. In contrast, the etiology of sporadic human breast cancer (BC) is unknown, but accumulating data indicate a possible viral origin also for these malignancies. The presence of MMTVenv-like sequences (MMTVels) in the human salivary glands and saliva supports the latter as possible route of inter-human dissemination. In the absence of the demonstration of a mouse-man transmission of MMTV, we considered the possibility that a cross-species transmission could have occurred in ancient times. Therefore, we investigated MMTVels in the ancient dental calculus, which originates from saliva and is an excellent material for paleovirology. The calculus was collected from 36 ancient human skulls, excluding any possible mouse contamination. MMTV-like sequences were identified in the calculus of 6 individuals dated from the Copper Age to the 17th century. The MMTV-like sequences were compared with known human endogenous betaretroviruses and with animal exogenous betaretroviruses, confirming their exogenous origin and relation to MMTV. These data reveal that a human exogenous betaretrovirus similar to MMTV has existed at least since 4,500 years ago and indirectly support the hypothesis that it could play a role in human breast cancer.

Purpose of review Leonardo Da Vinci possessed one of humanity's greatest minds, known for exploring the boundaries of art and science. The discipline of facial plastic surgery also relies on art and science for its advancement. This review focuses on key elements of Leonardo Da Vinci's work, and how they relate to concepts within facial plastic surgery. Recent findings Leonardo Da Vinci was a self-taught creative genius. Common themes that permeated his art were those of proportion, perspective, light and shadow, anatomy, and science. These principles are reflected in key aspects of facial plastic surgery, such as facial analysis, human gaze, facial subunits, surgery of the craniofacial skeleton, and evidence-based medicine. Summary Leonardo Da Vinci's approach to scientific inquiry and artistic beauty strikes a balance from which facial plastic surgeons have much to learn. In depth study of how Leonardo Da Vinci viewed the world furthers the analytical and creative sides of a facial plastic surgeon as well as informs their personal development.

Effective population size reflects the history of population growth, contraction, and structuring. When the effect of structuring is negligible, the inferred trajectory of the effective population size can be informative about the key events in the history of a population. We used the IBDNe and DoRIS approaches, which exploit the data on IBD sharing between genomes, to reconstruct the recent effective population size in two population datasets of Russians from Eastern European plain: (1) ethnic Russians sampled from the westernmost part of Russia; (2) ethnic Russians, Bashkirs, and Tatars sampled from the Volga-Ural region. In this way, we examined changes in effective population size among ethnic Russians that reside in their historical area at the West of the plain, and that expanded eastward to come into contact with the indigenous peoples at the East of the plain. We compared the inferred demographic trajectories of each ethnic group to written historical data related to demographic events such as migration, war, colonization, famine, establishment, and collapse of empires. According to IBDNe estimations, 200 generations (~6000 years) ago, the effective size of the ancestral populations of Russians, Bashkirs, and Tatars hovered around 3,000, 30,000, and 8,000 respectively. Then, the ethnic Russians exponentially grew with increasing rates for the last 115 generations and become the largest ethnic group of the plain. Russians do not show any drop in effective population size after the key historical conflicts, including the Mongol invasion. The only exception is a moderate drop in the 17th century, which is well known in Russian history as The Smuta. Our analyses suggest a more eventful recent population history for the two small ethnic groups that came into contact with ethnic Russians in the Volga-Ural region. We found that the effective population size of Bashkirs and Tatars started to decrease during the time of the Mongol invasion. Interestingly, there is an even stronger drop in the effective population size that coincides with the expansion of Russians to the East. Thus, 15–20 generations ago, i.e. in the 16–18th centuries in the trajectories of Bashkirs and Tatars, we observe the bottlenecks of four and twenty thousand, respectively. Our results on the recent effective population size correlate with the key events in the history of populations of the Eastern European plain and have importance for designing biomedical studies in the region.

Health workers offer their skills and care to COVID-19 pandemic patients, just as St Roch offered healing to those stricken by bubonic plague during the Renaissance. This article interprets 3 works of art in light of Roch's story of illness and recovery and applies key insights of ethical, artistic, and clinical relevance to the COVID-19 pandemic.

This paper explores the heritage and the essential significance of worship of the twin Christian saints -St. Cosmas and St. Damian- in the history of medicine. These saints are well known in Western culture as one of the leading Christian saints to heal diseases, whose cults have spread to Europe through Byzantium, which have continued to spread widely to the present, starting from areas where Christianity had been proselytized. Although it is true that their life journeys have undergone many processes of embellishment and beautification over the course of time, the attributes that distinctively characterize the two saints exist apart from such mythical fabrications. This paper categorizes the characteristics of the two saints as being those of “professional doctors,” “ideal doctors,” and “holders of healing powers” as intermediaries of God, examining how these characteristics came to affect various medical organizations during the era when Medieval medicine was gradually transitioning toward a rational approach based on reason. In addition, it discusses how some of the practices of ancient temple medicine were transplanted into the Christian culture, the process by which it finally arrived at human doctors through the two saints, and how it affected the establishment of professional work ethics -albeit in nascent form- as their medical ethics came to be accepted and practiced by the Medieval guild of surgeons. Furthermore, the paper considers how the existence of the two saints has acquired symbolism in modern medicine, which has made remarkable progress in organ transplantation, and in particular, how it constitutes a significant part of the history of organ transplantation. It is not easy to objectify and attach meaning to an era that was substantially influenced by myths, legends, or religious events. This is because it is easy to fall into the trap of simplifying and passing judgment on the past based on the realities of the present day, without making efforts to understand the unique circumstances and contexts of the past. This is especially the case when the distinction between “religious events” and “medical events” is ambiguous, or when dealing with a social culture where religious influence was paramount. From a broader perspective, the study of St. Cosmas and St. Damian is not concerned with the rights or wrongs of religious myths amid the advancement of medicine and its adherence to science and reason, but with the attempt at a deep and broad understanding of human diseases and human conditions of being prone to such diseases throughout life.

In this article, I first explored the process and its characteristics of the reorganization of the medical institution in the early Chosun Dynasty. In the early Chosun Dynasty, medical institutions of Naeuiwon, Jeonuigam, Hyeminseo, Hwalinseo, Jesaengwon were operated. From the examining the history, members, and roles of these institutions, it can be said that Chosun was aimed at Minbon Thought(For the people) of Neo-Confucianism and a one-sided centralized system. To understand the meaning of the change process of these medical institutions, we should pay attention to the social structure and ruling ideology of the late Koryo period. In other words, the autonomy and publicness of the people expanded in the land system of Koryo, while on the other hand, it became important to overcome the inefficiency of Buddhism, which was a dominant ideology. The movement to reflect the strengthened status of the people into the public national system by taking the Neo-Confucianism as the dominant ideology has been strengthened, and the medical rights of all the people have been guaranteed. But it did not mean that the Minbon Thought(For the people) of NeoConfucianism put the people first. The reason why the medical institution was organized in the order of Naeuiwon → Jeonuigam → Hyeminseo → Hwalinseo was because the theory of essence and end(本末論) of Neo-Confucianism was projected. At the same time, this hierarchical structure was also coincided with the statusclass structure of Chosun, which peaked at the royal family as the highest ruling class. For this reason, the status of the medical institutions for the people, Hyeminseo and Hwalinseo was low.

The Indian Ocean Dipole (IOD) affects climate and rainfall across the world, and most severely in nations surrounding the Indian Ocean1–4. The frequency and intensity of positive IOD events increased during the twentieth century5 and may continue to intensify in a warming world6. However, confidence in predictions of future IOD change is limited by known biases in IOD models7 and the lack of information on natural IOD variability before anthropogenic climate change. Here we use precisely dated and highly resolved coral records from the eastern equatorial Indian Ocean, where the signature of IOD variability is strong and unambiguous, to produce a semi-continuous reconstruction of IOD variability that covers five centuries of the last millennium. Our reconstruction demonstrates that extreme positive IOD events were rare before 1960. However, the most extreme event on record (1997) is not unprecedented, because at least one event that was approximately 27 to 42 per cent larger occurred naturally during the seventeenth century. We further show that a persistent, tight coupling existed between the variability of the IOD and the El Nino/Southern Oscillation during the last millennium. Indo-Pacific coupling was characterized by weak interannual variability before approximately 1590, which probably altered teleconnection patterns, and by anomalously strong variability during the seventeenth century, which was associated with societal upheaval in tropical Asia. A tendency towards clustering of positive IOD events is evident in our reconstruction, which—together with the identification of extreme IOD variability and persistent tropical Indo-Pacific climate coupling—may have implications for improving seasonal and decadal predictions and managing the climate risks of future IOD variability. Coral records indicate that the variability of the Indian Ocean Dipole over the last millennium is strongly coupled to variability in the El Nino/Southern Oscillation and that recent extremes are unusual but not unprecedented.

The anatomical textbook in the late Middle Ages was one part of a greater pedagogical process that involved students’ seeing, hearing, reading, and eventually knowing information about the human body. By examining the role of the anatomical textbook and accompanying bodily images in anatomical learning, this article illuminates the complexity and self-consciousness of anatomical education in the medieval university, as professors focused on ways to enhance student memory of the material. Traditionally, the history of anatomy has been heavily influenced by the anatomical Renaissance of the late-sixteenth century, highlighting a focus on innovative medical knowledge and the scientific method. However, if we engage a pedagogical lens when looking at these medieval authors, it becomes quickly obvious that the whole point of university medicine was not to explore unknown boundaries and discover new ideas of medicine, but rather to communicate the current and established body of knowledge to those not familiar with it.

My essay focuses on Charles Rosenberg's provocative and enduring ideal type of epidemic drama in three acts, which he assembled from a vast knowledge of disease history that stretched from the end of the seventeenth century to his then-present pandemic, HIV/AIDS of the 1980s. Reaching back to the Plague of Athens, my essay elaborates on Rosenberg's dramaturgy by questioning whether blame, division, and collective violence were so universal or even the dominant "acts" of epidemics not only before the nineteenth century but to the present. Instead, with certain pandemics such as yellow fever in the Deep South or the Great Influenza of 1918–20, unity, mass volunteerism, and self-abnegation played leading roles. Finally, not all epidemics ended "with a whimper" as attested by the long early modern history of plague. These often concluded literally with a bang: lavish planning of festivals of thanksgiving, choreographed with processions, innumerable banners, commissions of paintings, ex-voto churches, trumpets, tambourines, artillery fire, and fireworks.

We have known the accommodation phenomenon since 400 BC. Hypotheses about its mechanisms varied widely for two millennia. Early in the 17th century, when people became more aware of ophthalmic optics, Scheiner and Descartes were close to solving that accommodation worked by changes in the lens. Others rejected their idea, and people even denied the existence of accommodation because there was no clear proof. In the early 19th century, evidence accumulated for accommodation mechanisms studying bird, fish, insect, mammal and human eyes. On the discovery of muscle fibres in the ciliary body, attention shifted to its role in accommodation. Around 1850, came the proof that accommodation occurs by a change in the anterior lens curvature. Still for another 50 years, controversies remained about the exact changes in the lens and the precise accommodation mechanism. On looking back, this is not surprising because only late in the 20th century did it become clear that one cannot extrapolate from the multitude of accommodation mechanisms in the animal kingdom to human eyes.

An archaeoparasitological analysis of the soil samples from Nadym Gorodok site of Western Siberia has been carried out in this study. The archaeological site was dated as the 13 to 18th century, being characterized as permafrost region ensuring good preservation of ancient parasite eggs. Parasite eggs as Opisthorchis felineus, Alaria alata, and Diphyllobothrium sp. were found in the archaeological soil samples, which made clear about the detailed aspects of Nadym Gorodok people’s life. We found the Diphyllobothrium sp. eggs throughout the 14 to 18th century specimens, allowing us to presume that raw or undercooked fish might have been commonly used for the foods of Nadym Gorodok inhabitants and their dogs for at least the past 400 years. Our study on Nadym Gorodok specimens also demonstrate that there might have been migratory interactions and strong economic ties between the people and society in Western Siberia, based on archaeoparasitological results of Opisthorchis felineus in Western Siberia.

The status or role of Shanghan Lun (Treatise on Cold Damage Diseases) in Joseon is quite different compared to neighboring China and Japan. This is a unique aspect that distinguishes Joseon's medicine from other East Asian countries at that time. Prior studies have conducted research on non-professional books of Shanghan Lun; however, this study aims to analyze the transmission and utilization of professional books of Shanghan Lun. In the citations of medical books in the first half of Joseon period, the domestic introduction of professional books of Shanghan Lun used at the time occurred mostly from the mid-thirteenth century to the first half of the fifteenth century. In particular, the version of professional books of Shanghan Lun quoted in Euibangyoochui (Classified Collection of Medical Prescriptions) were centered on the Yuan edition. In other words, the acceptance of the theory of Cold Damage Diseases was based on the Yuan's medicine. Professional books of Shanghan Lun, which were published separately during the compilation or publication of Euibangyoochui, were intentionally selected. It is important to identify their characteristics. First of all, Shanghan Leishu (Classified Book of Cold Damage) was used as a textbook of Cold Damage in the first half of Joseon dynasty because the author of this book, Yang Shizhen and his practice acted as the basic text. The nature of Shanghan Leishu, which pursued the integration of "several symptoms of internal medicine" and "Cold Damage" instead of pursuing independent medicine of Cold Damage with different internal medicines, may have had some influence in forming the uniqueness of Joseon's medicine of Cold Damage. Shanghanfu (Harm Caused by Cold: A Poem) was an introduction for easy access to formal Cold Damage's content. Shanghanfu is presumed to be a medical book made out of prose poems, the core of Shanghanzhizhangtu. Non-professional books of Shanghanlun have also been cited in the first half of Joseon period's medical texts in relation to Cold Damage. However, these books were not used as textbooks in medical bureaucracy's education. The exclusion of major Cold Damage-related texts from the medical bureaucracy's education may have hampered the development of Joseon's Cold Damage medicine.

This work is based on the study of 150 majolica vases dated back to the mid XVII century that once preserved medicinal remedies prepared in the ancient Pharmacy annexed to the Ospedale Maggiore Ca’ Granda in Milan (Lombardy, Italy). The Hortus simplicium was created in 1641 as a source of plant-based ingredients for those remedies. The main objective of the present work is to lay the knowledge base for the restoration of the ancient Garden for educational and informative purposes. Therefore, the following complementary phases were carried out: (i) the analysis of the inscriptions on the jars, along with the survey on historical medical texts, allowing for the positive identification of the plant ingredients of the remedies and their ancient use as medicines, (ii) the bibliographic research in modern pharmacological literature in order to validate or refute the historical uses, (iii) the realization of the checklist of plants potentially present in cultivation at the ancient Garden, concurrently with the comparison with the results of a previous in situ archaeobotanical study concerning pollen grains. For the species selection, considerations were made also regarding drug amounts in the remedies and pedoclimatic conditions of the study area. Out of the 150 vases, 108 contained plant-based remedies, corresponding to 148 taxa. The remedies mainly treated gastrointestinal and respiratory disorders. At least one of the medicinal uses was validated in scientific literature for 112 out of the 148 examined species. Finally, a checklist of 40 taxa, presumably hosted in the Hortus simplicium, was assembled.

Leonardo da Vinci, the Renaissance polymath, is still recognized today—above all for his oil paintings and mechanical inventions. His anatomical studies have attracted less attention, even though he devoted over 30 years of his life to them. This paper outlines Leonardo's career and research methods and focuses on the importance of his medical images for anatomical research and teaching. Following a short presentation of the state of (dental) medicine in the early Renaissance period, it offers a description of five of his cranial drawings that show the anatomy of the teeth, the nervous and vascular system on inner and outer tables of the skull and the paranasal sinuses in great detail. Leonardo da Vinci had obviously discovered and depicted the maxillary sinus 150 years before the anatomist Nathaniel Highmore, who is usually credited with this discovery. Other anatomical drawings by Leonardo address the correct human dental formula and describe the morphology of the four types of teeth. His handwritten notes show that he recognized the connection between tooth form and function. Finally, this paper evaluates the influence of these discoveries and innovations on the development of dentistry and its establishment as a scientific discipline. There is no doubt that Leonardo da Vinci's preoccupation with the anatomy of the maxillofacial region influenced the development of anatomy and dentistry, even though he never published his anatomical research., Leonardo da Vinci, the Renaissance polymath, conducted detailed anatomical studies. His anatomical drawings and notes address the human dental formula, describe the morphology of the different types of teeth, and highlight the relationship between tooth shape and function. Leonardo described the maxillary sinus 150 years earlier than the anatomist Nathaniel Highmore. Finally, the paper discusses his influence on the development of dentistry.

Finding order in disorder is a hallmark of science and art. In the time of Leonardo da Vinci, the schism between science and art had yet to arise. In fact, Leonardo freely used scientific methods for his art and vice versa; for example, when he used his observations of turbulent, whirling water to guide his artistic imagination. Half a millennium later, a cornerstone of modern biology is the continuing search for order in dynamic processes. In neuroscience, the search has focussed on understanding complex spacetime brain dynamics. Recently, turbulence has been shown to be a guiding principle underlying the necessary information processing, supporting Leonardo's search for order in disorder. Here, we argue that Leonardo's seminal insights have ongoing relevance for modern neuroscience.

Journal of Preventive Medicine and Hygiene, Vol. 61 No. 1s1 (2020): Tuberculosis. The Never Ending Story: past, present and Future Challeng (Parte I)

This review traces the growing burden of cancer in India from antiquity. We searched PubMed, Internet Archive, the British Library, and several other sources for information on cancer in Indian history. Paleopathology studies from Indus Valley Civilization sites do not reveal any malignancy. Cancer-like diseases and remedies are mentioned in the ancient Ayurveda and Siddha manuscripts from India. Cancer was rarely mentioned in the medieval literature from India. Cancer case reports from India began in the 17th century. Between 1860 and 1910, several audits and cancer case series were published by Indian Medical Service doctors across India. The landmark study by Nath and Grewal used autopsy, pathology, and clinical data between 1917 and 1932 from various medical college hospitals across India to confirm that cancer was a common cause of death in middle-aged and elderly Indians. India’s cancer burden was apparently low as a result of the short life expectancy of the natives in those times. In 1946, a national committee on health reforms recommended the creation of sufficient facilities to diagnose and manage the increasing cancer burden in all Indian states. Trends from the Mumbai population-based cancer registry revealed a four-fold increase in patients with cancer from 1964 to 2012. Depending on the epidemiologic transition level, wide interstate variation in cancer burden is found in India. We conclude that cancer has been recognized in India since antiquity. India’s current burden of a million incident cancers is the result of an epidemiologic transition, improved cancer diagnostics, and improved cancer data capture. The increase in cancer in India with wide interstate variations offers useful insights and important lessons for developing countries in managing their increasing cancer burdens.

Until well in the 19th century, the Aristotelian concept of the scala naturae (ladder of nature) was the most common biological theory among Western scientists. It dictated that only humans possessed a rational soul that provided the ability to reason and reflect. Michel Eyquem de Montaigne (1533-1592) was the first philosopher influential enough to lastingly posit that animals are cognitive creatures. His view stirred a fierce controversy, with René Descartes (1596-1650) leading among his many adversaries. Only after it became accepted that animals and humans alike have cognitive abilities, did the research on the influence of conscious awareness and intention on the behavior of an animal become possible in the 20th century. We found the anatomist Andreas Vesalius (1515-1564) to have already rejected the Aristotelian view on the lack of the rational soul in animals in his 1543 opus magnum De Humani Corporis Fabrica Libri Septem. His observation "that there is a difference in size according to the amount of reason that they seem to possess: man's brain is the largest, followed by the ape's, the dog's, and so on, corresponding to the amount of rational force that we deduce each animal to have" resonated some 330 years later when Darwin concluded that "the difference in mind between man and the higher animals, great as it is, certainly is one of degree and not of kind." We conclude that Vesalius was instrumental in breaking with two millenniums of dominance of the concept of lack of animal cognition.

RÉSUMÉ L’histoire nous a appris que les émergences virales ne sont pas des phénomènes nouveaux. La variole, venue d’Asie, est probablement apparue en Europe dès le Ve siècle et la fièvre jaune a émergé en Amérique au XVIe siècle, importée d’Afrique par la traite des Noirs. La dengue est apparue au XVIIIe siècle simultanément en Asie du Sud-est, en Afrique et en Amérique du Nord. Quant à la « grippe espagnole », elle a tué, en 1918–1919, entre 25 et 40 millions de personnes dans le monde. La deuxième moitié du XXe siècle a été marquée par de nombreuses émergences virales dont celle du Sida en 1981. Mais, ce qui caractérise l’évolution récente des émergences virales, c’est que non seulement de nouveaux virus émergent de façon répétée, mais qu’ils ont de plus en plus tendance à envahir de nouveaux pays, voire d’autres continents, et de s’y installer de façon plus ou moins durable. Des exemples de cette situation épidémique nouvelle sont donnés avec les infections à virus Nipah, West Nile, de la fièvre de la Vallée du Rift, du SRAS, du monkeypox, de la grippe aviaire H5N1 et Chikungunya. Les causes, multiples et complexes, de ces émergences et réémergences sont brièvement analysées.

In 1708, Adam Christian Thebesius, a 22-year-old student at Leiden University, presented his graduate thesis, Disputatio medica inauguralis de circulo sanguinis in corde. More than a doctoral dissertation, this groundbreaking work opened new channels into the study of the human coronary venous system. Thebesius' theory about the vascular communication between the coronary arteries and the chambers of the heart helped to advance understanding of hemodynamic principles and to clarify the physiologic pathways of the coronary circulation. The following article—the third in a trilogy about Lower Silesian scientists—provides an overview of the life story and achievements of this Silesian physician and innovator, whose name was immortalized in 2 cardiac eponyms: the Thebesian veins and the Thebesian valve.

This paper integrates our knowledge from traditional Chinese medical texts and archeological findings to discuss parasitic loads in early China. Many studies have documented that several different species of eukaryotic endoparasites were present in early human populations throughout China. Nevertheless, comprehensive paleoparasitological records from China are patchy, largely due to taphonomic and environmental factors. An examination of early Chinese medical texts allows us to fill in some of the gaps and counteract apparent biases in the current archeoparasitological records. By integrating the findings of paleoparasitology with historic textual sources, we show that parasites have been affecting the lives of humans in China since ancient times. We discuss the presence and prevalence of three groups of parasites in ancient China: roundworm (Ascaris lumbricoides), Asian schistosoma (Schistosoma japonicum), and tapeworm (Taenia sp.). We also examine possible factors that favored the spread of these endoparasites among early humans. Therefore, this paper not only aims to reveal how humans have been affected by endoparasites, but also addresses how early medical knowledge developed to cope with the parasitic diseases.
