[Artisanal Surgery in the Early 17th Century. The Practice Journal of a Barber-Surgeon in Münster]

This paper presents and analyzes the practice journal of a barber-surgeon in the town of Münster, in Northern Germany, in which he recorded about 950 cases he treated between 1602 and 1614. Based on this source, it examines the clientele and the fees of a German barber-surgeon in the early seventeenth century, and looks at the injuries and complaints for which patients sought his treatment.

Genetic continuity and change among the Indigenous peoples of California

Before the colonial period, California harboured more language variation than all of Europe, and linguistic and archaeological analyses have led to many hypotheses to explain this diversity1. We report genome-wide data from 79 ancient individuals from California and 40 ancient individuals from Northern Mexico dating to 7,400-200 years before present (BP). Our analyses document long-term genetic continuity between people living on the Northern Channel Islands of California and the adjacent Santa Barbara mainland coast from 7,400 years BP to modern Chumash groups represented by individuals who lived around 200 years BP. The distinctive genetic lineages that characterize present-day and ancient people from Northwest Mexico increased in frequency in Southern and Central California by 5,200 years BP, providing evidence for northward migrations that are candidates for spreading Uto-Aztecan languages before the dispersal of maize agriculture from Mexico2-4. Individuals from Baja California share more alleles with the earliest individual from Central California in the dataset than with later individuals from Central California, potentially reflecting an earlier linguistic substrate, whose impact on local ancestry was diluted by later migrations from inland regions1,5. After 1,600 years BP, ancient individuals from the Channel Islands lived in communities with effective sizes similar to those in pre-agricultural Caribbean and Patagonia, and smaller than those on the California mainland and in sampled regions of Mexico.

Diseases of Africans, an African disease: transformations of quijila between Central West Africa and Minas Gerais, in Brazil, in the seventeenth and eighteenth centuries

This article discusses the origin of quijila/kijila in Central West African culture, more particularly in the cultural universe of the Imbangala (Jaga) and the Ambundu and Kimbundu populations who lived in the Portuguese regions of Angola and the Congo in the seventeenth and eighteenth centuries. Following this, it investigates how the concept of quijila was structured, comprehended, and transformed, both in Africa, where it was basically a food prohibition, but whose applications and meanings varied; and in Brazil, to where it was transported in the 1700s, and where it transformed into a disease which attacked blacks, especially Africans of various origins, being framed as such in the Hippocratic-Galen universe characteristic of that time.

Antoni van Leeuwenhoek 1723-2023: a review to commemorate Van Leeuwenhoek's death, 300 years ago : For submission to Antonie van Leeuwenhoek journal of microbiology

In the 300 years since Van Leeuwenhoek died, some of the details around his life and his work have provided material for discussion or dispute. As archives and libraries are being scanned and technology improves, information is becoming more readily available. This review therefore aims to take a new look at some of those discussions, and Van Leeuwenhoek's possible experimental methods. Digital photography has made it possible to show exactly what can be seen through his simple microscopes, and how he could have obtained his results by, for example, modifying his microscopes and lighting. Equally, the completion of the series known as the Collected Letters, begun in 1931 with volume 1 published in 1939 and to be completed in 2023, allows researchers to see complete letters in English and modern Dutch. Theories about experimental methods can be tested and the results recorded photographically. Additionally, new, non-destructive techniques such as neutron tomography have improved the evaluation of the authenticity of surviving microscopes.

The history of Danish neuroscience

The history of Danish neuroscience starts with an account of impressive contributions made at the 17th century. Thomas Bartholin was the first Danish neuroscientist, and his disciple Nicolaus Steno became internationally one of the most prominent neuroscientists in this period. From the start, Danish neuroscience was linked to clinical disciplines. This continued in the 19th and first half of the 20th centuries with new initiatives linking basic neuroscience to clinical neurology and psychiatry in the same scientific environment. Subsequently, from the middle of the 20th century, basic neuroscience was developing rapidly within the preclinical university sector. Clinical neuroscience continued and was even reinforced during this period with important translational research and a close co-operation between basic and clinical neuroscience. To distinguish 'history' from 'present time' is not easy, as many historical events continue in present time. Therefore, we decided to consider 'History' as new major scientific developments in Denmark, which were launched before the end of the 20th century. With this aim, scientists mentioned will have been born, with a few exceptions, no later than the early 1960s. However, we often refer to more recent publications in documenting the developments of initiatives launched before the end of the last century. In addition, several scientists have moved to Denmark after the beginning of the present century, and they certainly are contributing to the present status of Danish neuroscience-but, again, this is not the History of Danish neuroscience.

[Brief introduction on compilation and editions of Yang ke xuan cui]

Yang ke xuan cui («») is a surgical work compiled by Chen Wenzhi () of the Ming Dynasty. There are few of research on the completion and author of the book. Based on the evidences in the local chronicles, the prefaces and postscripts of the book, it has been verified that the book was originally completed no later than 1591, and Chen Wenzhi passed away no later than 1623. After investigating the 6 editions collected by 8 institutions, a collection of 11 books in total, by comparing the characteristics and circulation relationship of each edition, two systems of circulation were sorted out: block-printed edition of Xu Xi () and review edition of Xu Dachun ().

Entwined African and Asian genetic roots of medieval peoples of the Swahili coast

The urban peoples of the Swahili coast traded across eastern Africa and the Indian Ocean and were among the first practitioners of Islam among sub-Saharan people1,2. The extent to which these early interactions between Africans and non-Africans were accompanied by genetic exchange remains unknown. Here we report ancient DNA data for 80 individuals from 6 medieval and early modern (AD 1250-1800) coastal towns and an inland town after AD 1650. More than half of the DNA of many of the individuals from coastal towns originates from primarily female ancestors from Africa, with a large proportion-and occasionally more than half-of the DNA coming from Asian ancestors. The Asian ancestry includes components associated with Persia and India, with 80-90% of the Asian DNA originating from Persian men. Peoples of African and Asian origins began to mix by about AD 1000, coinciding with the large-scale adoption of Islam. Before about AD 1500, the Southwest Asian ancestry was mainly Persian-related, consistent with the narrative of the Kilwa Chronicle, the oldest history told by people of the Swahili coast3. After this time, the sources of DNA became increasingly Arabian, consistent with evidence of growing interactions with southern Arabia4. Subsequent interactions with Asian and African people further changed the ancestry of present-day people of the Swahili coast in relation to the medieval individuals whose DNA we sequenced.

Advances in Microscopy Tech Offer Better Views

Microscopes have come a very long way since the 1600s when Henry Power, Robert Hooke, and Anton van Leeuwenhoek began publishing the first views of plant cells and bacteria. The major inventions of contrast, electron, and scanning tunneling microscopes didn't arrive until the 20th century, and the men behind them all earned Nobel Prizes in physics for their efforts. Today, innovations in microscopy are coming at a fast and furious rate with new technologies providing first-time views and information about biological structures and activity, and opening up new avenues for disease therapies.

Physico-mathematics and the life sciences: experiencing the mechanism of venous return, 1650s-1680s

This article deals with physico-mathematical approaches to anatomy in post-Harveyan physiology. But rather than looking at questions of iatromechanics and animal locomotion, which often attracted this approach, I look at the problem of how blood returned to the heart - a part of the circulation today known as venous return but poorly researched in the early modern period. I follow the venous return mechanisms proposed by lesser-known authors in the mechanization of anatomy, such as Jean Pecquet (1622-1674) and Nicolaus Steno (1638-1686), alongside the more famous Giovanni Alfonso Borelli (1608-1679). Their mechanisms differed only in small details. Yet, these minor differences highlight significant aspects of the mechanization of the life sciences in the seventeenth century. First, they relied more on observations than hitherto acknowledged, even if only indirectly. Second, their mechanisms drew more from the physico-mathematical disciplines than from the trending corpuscularian philosophies of their time. Finally, these mechanisms led to a more accurate understanding of the circulation that remains valid today, thus revealing their cognitive benefits. In short, through the single problem of how blood returned to the heart, this article portrays the increasing complexity of anatomy in the early modern period.

A Short History of Plant Light Microscopy

When the microscope was first introduced to scientists in the 17^th century, it started a revolution. Suddenly, a whole new world, invisible to the naked eye, was opened to curious explorers. In response to this realization, Nehemiah Grew, an English plant anatomist and physiologist and one of the early microscopists, noted in 1682 "that Nothing hereof remains further to be known, is a Thought not well Calculated". Since Grew made his observations, the microscope has undergone numerous variations, developing from early compound microscopes-hollow metal tubes with a lens on each end-to the modern, sophisticated, out-of-the-box super-resolution microscopes available to researchers today. In this Overview article, I describe these developments and discuss how each new and improved variant of the microscope led to major breakthroughs in the life sciences, with a focus on the plant field. These advances start with Grew's simple and-at the time-surprising realization that plant cells are as complex as animals cells, and that the different parts of the plant body indeed qualify to be called "organs", then move on to the development of the groundbreaking "cell theory" in the mid-19^th century and the description of eu- and heterochromatin in the early 20^th century, and finish with the precise localization of individual proteins in intact, living cells that we can perform today. Indeed, Grew was right; with ever-increasing resolution, there really does not seem to be an end to what can be explored with a microscope. © 2022 The Authors.

"Following Anne Lister: Continuity and queer history before and after the late nineteenth century"

This article addresses the question of whether Anne Lister can be considered a lesbian through a reassessment of how the modern period is conceptualized within the history of sexuality. Returning to the original texts that first defined the history of sexuality project, the article emphasized that those texts indicate that the mechanisms of biopower and identity formation based on cultural texts undergo their most significant shift in the late seventeenth and early eighteenth centuries, rather than in the late nineteenth. The formation of sexuality as a disciplinary mechanism, and identities based on it, originated in the late nineteenth century, but many of the mechanisms through which this occurred were in operation earlier. Much of what is now known about gender and sexuality in the eighteenth and early nineteenth centuries was unknown at the time that the history of sexuality project was first formulated, leading to a starker divide being drawn between the late nineteenth century and earlier periods than is warranted. This article argues that the example of Anne Lister can lead to a better appreciation of the continuities in how cultural texts shaped understandings of desire from the early eighteenth century forward.

Overview of Dioscorides' recipes in Croatian books of folk recipes

The aim of this paper is to present an overview of Dioscorides' recipes from his work De materia medica which are found in Croatian folk medicine preserved in books of folk recipes called ljekaruše. The particularities of five published and analysed Croatian books of folk recipes from the 17 th and 18 th century are examined. Recipes with drugs of herbal and animal origin, which are most often mentioned in Croatian books of folk recipes, and which were available in folk medicine at the time, are compared with those from Dioscorides' work. Many herbal drugs described in books of folk recipes are today used in contemporary phytotherapy, and modern biomedical research reveals new bioactive substances and confirms new and potential biological activities in medicinal plants used in folk medicine, which is the basis for further study of De materia medica by Dioscorides and ethnomedicinal collections. Croatian books of folk recipes are a valuable resource for multidisciplinary study, including for medicinal and pharmaceutical historians, philologists and ethnologists.

Thomas Willis' legacy on the 400th anniversary of his birth

To celebrate the 400^th anniversary of the birth of Thomas Willis, his main contributions to the development of neurosciences, in particular neurology, are presented. Willis coined the term neurology and contributed significantly to the field of neuroanatomy, with the description of the arterial circle-located at the base of the brain-, which bears his name. He also described the striatum and cranial nerves. Furthermore, as a clinical neurologist, Willis participated in the description of various diseases, including myasthenia gravis and restless legs syndrome.

The Beginnings of English Paracelsian Lexicography: Two Collections of Words from Elizabethan Cambridge

This article identifies the first two collections of Paracelsian words to have been printed in England: a body of 153 new and rare words, or new senses of existing words, dispersed in the third edition of Thomas Thomas's Latin-English Dictionarium of 1592, and a list of forty-three words forming part of Joseph Hall's Latin prose satire Mundus alter et idem, published in 1605. The Paracelsian material in the Dictionarium has been practically unknown until now, and the Paracelsian material in Mundus alter et idem has been insufficiently studied. Both collections of words are edited here, with discussion of their sources and the principles on which they were selected, and with discussion of their influence for the period of more than half a century when they were the only collections of Paracelsian words printed in England.

The medieval cell doctrine: Foundations, development, evolution, and graphic representations in printed books from 1490 to 1630

The medieval cell doctrine was a series of related psychological models based on ancient Greco-Roman ideas in which cognitive faculties were assigned to "cells," typically corresponding to the cerebral ventricles. During Late Antiquity and continuing during the Early Middle Ages, Christian philosophers attempted to reinterpret Aristotle's De Anima, along with later modifications by Herophilos and Galen, in a manner consistent with religious doctrine. The resulting medieval cell doctrine was formulated by the fathers of the early Christian Church in the fourth and fifth centuries. Printed images of the doctrine that appeared in medical, philosophical, and religious works, beginning with "graphic incunabula" at the end of the fifteenth century, extended and evolved a manuscript tradition that had been in place since at least the eleventh century. Some of these early psychological models just pigeonholed the various cognitive faculties in different non-overlapping bins within the brain (albeit without any clinicopathologic evidence supporting such localizations), while others specifically promoted or implied a linear sequence of events, resembling the process of digestion. By the sixteenth century, printed images of the doctrine were usually linear three-cell versions with few exceptions having four or five cells. Despite direct challenges by Massa and Vesalius in the sixteenth century, and Willis in the seventeenth century, the doctrine saw its most elaborate formulations in the late-sixteenth and early-seventeenth centuries with illustrations by the Paracelsan physicians Bacci and Fludd. Overthrow of the doctrine had to await abandonment of Galenic cardiovascular physiology from the late-seventeenth to early-eighteenth centuries.

The real Theriac - panacea, poisonous drug or quackery?

ETHNOPHARMACOLOGICAL RELEVANCE

Theriac is considered the most popular cure-all multi-ingredient medicine and has been used for more than two millennia. It has also been used as one of the most important anti-epidemic drugs up to the 19th c., treated as an emergency medicine in case of e.g. bubonic plague.

AIM OF THE STUDY

Until now, no reliable information regarding the pharmacological effect of the treacle was available, including its possible toxic or narcotic properties. In order to change the state of knowledge in this matter we have selected the Theriac recipe that had been actually used for producing the treacle in 1630, which was confirmed by the official municipal documents of the time.

METHODS

The recipe was written in Latin, with the use of pre-Linnean nomenclature and then apothecary common names, which required translation into the modern scientific language in order to get reliable pharmacological conclusions. The information from historical sources has been compiled with the pharmacological data concerning the most potent compounds, which for the first time made it possible to calculate the amounts of active compounds in the doses taken by then patients.

RESULTS

Only two species included in Theriac can be harmful in humans: poppy and sea squill, but in both cases the calculated quantity of morphine and cardiac glycosides, respectively, were below toxic level. There are no indications, both from the historical and pharmacological point of view, for Theriac being toxic or narcotic in patients, when used as prescribed.

CONCLUSIONS

As for now, the most probable is that the treacle owed its postulated efficacy in the main indications to the placebo effect. Still, the results should be further confirmed by reconstructing the actual Theriac and subjecting it to modern tests and analyses.

Ca' Granda, Hortus simplicium: Restoring an Ancient Medicinal Garden of XV-XIX Century in Milan (Italy)

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.

Bioarchaeological insights into the last plague of Imola (1630-1632)

The plague of 1630-1632 was one of the deadliest plague epidemics to ever hit Northern Italy, and for many of the affected regions, it was also the last. While accounts on plague during the early 1630s in Florence and Milan are frequent, much less is known about the city of Imola. We analyzed the full skeletal assemblage of four mass graves (n = 133 individuals) at the Lazaretto dell'Osservanza, which date back to the outbreak of 1630-1632 in Imola and evaluated our results by integrating new archival sources. The skeletons showed little evidence of physical trauma and were covered by multiple layers of lime, which is characteristic for epidemic mass mortality sites. We screened 15 teeth for Yersinia pestis aDNA and were able to confirm the presence of plague in Imola via metagenomic analysis. Additionally, we studied a contemporaneous register, in which a friar recorded patient outcomes at the lazaretto during the last year of the epidemic. Our multidisciplinary approach combining historical, osteological and genomic data provided a unique opportunity to reconstruct an in-depth picture of the last plague of Imola through the city's main lazaretto.

Acupuncture, from the ancient to the current

Acupuncture is characterized by the insertion of a fine metal needle through the skin of the human body at an acupuncture point (acupoint) in Traditional Chinese Medicine (TCM). It is an ancient form of therapy, and has a long history of prosperity and decline. Due to the persistent efforts of TCM practitioners, a number of well-designed clinical trials regarding acupuncture have been published in the past decade. Besides, numerous basic researches aiming to reveal the mechanisms of acupuncture have also been conducted. Several scientific explanations have been obtained to interpret the arcane TCM theory. This review provides brief information of acupuncture, including its history, status, evidence, and mechanisms.

Batavia shipwreck timbers reveal a key to Dutch success in 17th-century world trade

Ocean-going ships were key to rising maritime economies of the Early Modern period, and understanding how they were built is critical to grasp the challenges faced by shipwrights and merchant seafarers. Shipwreck timbers hold material evidence of the dynamic interplay of wood supplies, craftmanship, and evolving ship designs that helped shape the Early Modern world. Here we present the results of dendroarchaeological research carried out on Batavia’s wreck timbers, currently on display at the Western Australian Shipwrecks Museum in Fremantle. Built in Amsterdam in 1628 CE and wrecked on its maiden voyage in June 1629 CE in Western Australian waters, Batavia epitomises Dutch East India Company (Verenigde Oostindische Compagnie, or VOC) shipbuilding. In the 17th century, the VOC grew to become the first multinational trading enterprise, prompting the rise of the stock market and modern capitalism. Oak (Quercus sp.) was the preferred material for shipbuilding in northern and western Europe, and maritime nations struggled to ensure sufficient supplies to meet their needs and sustain their ever-growing mercantile fleets and networks. Our research illustrates the compatibility of dendrochronological studies with musealisation of shipwreck assemblages, and the results demonstrate that the VOC successfully coped with timber shortages in the early 17th century through diversification of timber sources (mainly Baltic region, Lübeck hinterland in northern Germany, and Lower Saxony in northwest Germany), allocation of sourcing regions to specific timber products (hull planks from the Baltic and Lübeck, framing elements from Lower Saxony), and skillful woodworking craftmanship (sapwood was removed from all timber elements). These strategies, combined with an innovative hull design and the use of wind-powered sawmills, allowed the Dutch to produce unprecedented numbers of ocean-going ships for long-distance voyaging and interregional trade in Asia, proving key to their success in 17^th-century world trade.

Resolving Indigenous village occupations and social history across the long century of European permanent settlement in Northeastern North America: The Mohawk River Valley ~1450-1635 CE

The timeframe of Indigenous settlements in Northeast North America in the 15th-17th centuries CE has until very recently been largely described in terms of European material culture and history. An independent chronology was usually absent. Radiocarbon dating has recently begun to change this conventional model radically. The challenge, if an alternative, independent timeframe and history is to be created, is to articulate a high-resolution chronology appropriate and comparable with the lived histories of the Indigenous village settlements of the period. Improving substantially on previous initial work, we report here high-resolution defined chronologies for the three most extensively excavated and iconic ancestral Kanien'kehá꞉ka (Mohawk) village sites in New York (Smith-Pagerie, Klock and Garoga), and a fourth early historic Indigenous site, Brigg's Run, and re-assess the wider chronology of the Mohawk River Valley in the mid-15th to earlier 17th centuries. This new chronology confirms initial suggestions from radiocarbon that a wholesale reappraisal of past assumptions is necessary, since our dates conflict completely with past dates and the previously presumed temporal order of these three iconic sites. In turn, a wider reassessment of northeastern North American early history and re-interpretation of Atlantic connectivities in the later 15th through early 17th centuries is required. Our new closely defined date ranges are achieved employing detailed archival analysis of excavation records to establish the contextual history for radiocarbon-dated samples from each site, tree-ring defined short time series from wood charcoal samples fitted against the radiocarbon calibration curve ('wiggle-matching'), and Bayesian chronological modelling for each of the individual sites integrating all available prior knowledge and radiocarbon dating probabilities. We define (our preferred model) most likely (68.3% highest posterior density) village occupation ranges for Smith-Pagerie of ~1478-1498, Klock of ~1499-1521, Garoga of ~1550-1582, and Brigg's Run of ~1619-1632.

The significance of pyrogenic polycyclic aromatic hydrocarbons in Borneo peat core for the reconstruction of fire history

The reconstruction of fire history is essential to understand the palaeoclimate and human history. Polycyclic aromatic hydrocarbons (PAHs) have been extensively used as a fire marker. In this work, the distribution of PAHs in Borneo peat archives was investigated to understand how PAHs reflect the palaeo-fire activity. In total, 52 peat samples were analysed from a Borneo peat core for the PAH analysis. Pyrogenic PAHs consist of 2–7 aromatic rings, some of which have methyl and ethyl groups. The results reveal that the concentration of pyrogenic PAHs fluctuated with the core depth. Compared to low-molecular-weight (LMW) PAHs, the high-molecular-weight (HMW) PAHs had a more similar depth variation to the charcoal abundance. This finding also suggests that the HMW PAHs were mainly formed at a local fire near the study area, while the LMW PAHs could be transported from remote locations.

Melancholia Scytharum: the early modern psychiatry of transgender identification

Herodotus's enigmatic Scythian theleia nousos/morbus femininus and its Hippocratic interpretation interested many early modern authors. Its seeming dimension of transgender identification invited various medico-psychological and psychiatric reflections, culminating in nosologist de Sauvages' tentative 1731 term, melancholia Scytharum. This article identifies pertinent discussions and what turn out to have been entangled, tentative psychologizations in late-seventeenth through mid-nineteenth-century mental medicine: of 'effeminacy of manners' (mollities animi such as observed in London's Beaux and mollies) and male homosexuality (amour antiphysique/grec); of the mental masculinity of some women (viragines, Amazones); of ubiquitous attributions of impotence to sorcery (anaphrodisia magica); and lastly, of transfeminine persons encountered throughout the New World and increasingly beyond.

X-ray computed tomography for non-invasive dendrochronology reveals a concealed double panelling on a painting from Rubens' studio

Dating the wood from historical art objects is a crucial step to ascertain their production time, and support or refute attribution to an artist or a workshop. Dendrochronology is commonly used for this purpose but requires access to the tree-ring pattern in the wood, which can be hindered by preparatory layers, polychromy, wax, or integrated frames. Here we implemented non-invasive dendrochronology based on X-ray computed tomography (CT) to examine a painting on panel attributed to Rubens' studio and its presumed dating around 1636 CE. The CT images achieved a resolution of 37.3 micron and revealed a double panelling, which was concealed by oak strips covering all four edges. The back (visible) board is made of deciduous oak (Quercus subg. Quercus), the most common type of wood used in 17th-century Netherlandish workshops, and was dated terminus post quem after 1557 CE. However, the front (original) board used for the painting has been identified through examination of the wood anatomy as a tropical wood, probably Swietenia sp., a species seldom used in Netherlandish paintings, and remains undated. Its very presence attests the global character of 17th-century trade, and demonstrates the use of exotic species in Flemish studios. The date of the oak board refutes previous results and suggests that this board was trimmed to meet the size of the tropical one, having been glued to it for conservation purposes or with deceiving intentions to pretend that the painting was made on an oak panel. These revelations have opened new lines of art historical inquiry and highlight the potential of X-ray CT as a powerful tool for non-invasive study of historical art objects to retrieve their full history.

The Story of Blood for Shock Resuscitation: How the Pendulum Swings

Whole blood transfusion (WBT) began in 1667 as a treatment for mental illness with predictably poor results. Its therapeutic utility and widespread use were initially limited by deficiencies in transfusion science and antisepsis. James Blundell, a British obstetrician, was recognized for the first allotransfusion in 1825. However, WBT did not become safe and therapeutic until the early 20^th century with the advent of reliable equipment, sterilization and blood typing. The discovery of citrate preservation in World War I allowed a separation of donor from recipient and introduced the practice of blood banking. During World War II, Elliott and Strumia were the first to separate whole blood into blood component therapy (BCT), producing dried plasma as a resuscitative product for "traumatic shock". During the 1970s, infectious disease, blood fractionation and financial opportunities further drove the change from WBT to BCT with little supporting data. Following a period of high-volume crystalloid and BCT resuscitation well into the early 2000's, measures to avoid the resulting iatrogenic resuscitation injury were developed under the concept of damage control resuscitation. Modern transfusion strategies for hemorrhagic shock target balanced BCT to reapproximate whole blood. Contemporary research has expanded the role of WBT to therapy for the acute coagulopathy of trauma and the damaged endothelium. Many US trauma centers are now using WBT as a front-line treatment in tandem with BCT for patients suffering hemorrhagic shock. Looking ahead, it is likely that WBT will once again be the resuscitative fluid of choice for patients in hemorrhagic shock.

Examining the trade-offs between human fertility and longevity over three centuries using crowdsourced genealogy data

The evolution theory of ageing predicts that reproduction comes with long-term costs of survival. However, empirical studies in human species report mixed findings of the relationship between fertility and longevity, which varies by populations, time periods, and individual characteristics. One explanation underscores that changes in survival conditions over historical periods can moderate the negative effect of human fertility on longevity. This study investigates the fertility-longevity relationship in Europe during a period of rapid modernisation (seventeenth to twentieth centuries) and emphasises the dynamics across generations. Using a crowdsourced genealogy dataset from the FamiLinx project, our sample consists of 81,924 women and 103,642 men born between 1601 and 1910 across 16 European countries. Results from multilevel analyses show that higher fertility has a significantly negative effect on longevity. For both women and men, the negative effects are stronger among the older cohorts and have reduced over time. Moreover, we find similar trends in the dynamic associations between fertility and longevity across four geographical regions in Europe. Findings and limitations of this study call for further investigations into the historical dynamics of multiple mechanisms behind the human evolution of ageing.

Ancient viral genomes reveal introduction of human pathogenic viruses into Mexico during the transatlantic slave trade

After the European colonization of the Americas, there was a dramatic population collapse of the Indigenous inhabitants caused in part by the introduction of new pathogens. Although there is much speculation on the etiology of the Colonial epidemics, direct evidence for the presence of specific viruses during the Colonial era is lacking. To uncover the diversity of viral pathogens during this period, we designed an enrichment assay targeting ancient DNA (aDNA) from viruses of clinical importance and applied it to DNA extracts from individuals found in a Colonial hospital and a Colonial chapel (16th-18th century) where records suggest that victims of epidemics were buried during important outbreaks in Mexico City. This allowed us to reconstruct three ancient human parvovirus B19 genomes and one ancient human hepatitis B virus genome from distinct individuals. The viral genomes are similar to African strains, consistent with the inferred morphological and genetic African ancestry of the hosts as well as with the isotopic analysis of the human remains, suggesting an origin on the African continent. This study provides direct molecular evidence of ancient viruses being transported to the Americas during the transatlantic slave trade and their subsequent introduction to New Spain. Altogether, our observations enrich the discussion about the etiology of infectious diseases during the Colonial period in Mexico.

Jacob Winslow (1669-1760): The surprising legacy of an anatomist

Jacob Winslow (1669-1760), a celebrated anatomist in his day, made his name publishing numerous medical treatises and writing the four-volume Anatomical exposition of the structure of the human body. He gives his name to the foramen of Winslow, and is credited with numerous significant findings in neuroanatomy and biomechanics. His life is characterised by meticulous devotion to his discipline and divided by a torturous religious conversion. In addition to his contributions to anatomy, he is famously remembered for his treatise on the uncertainty of the signs of death, which has influenced practices surrounding death down to the present day.

Cycles and circulation: a theme in the history of biology and medicine

We invite systematic consideration of the metaphors of cycles and circulation as a long-term theme in the history of the life and environmental sciences and medicine. Ubiquitous in ancient religious and philosophical traditions, especially in representing the seasons and the motions of celestial bodies, circles once symbolized perfection. Over the centuries cyclic images in western medicine, natural philosophy, natural history and eventually biology gained independence from cosmology and theology and came to depend less on strictly circular forms. As potent 'canonical icons', cycles also interacted with representations of linear and irreversible change, including arrows, arcs, scales, series and trees, as in theories of the Earth and of evolution. In modern times life cycles and reproductive cycles have often been held to characterize life, in some cases especially female life, while human efforts selectively to foster and disrupt these cycles have harnessed their productivity in medicine and agriculture. But strong cyclic metaphors have continued to link physiology and climatology, medicine and economics, and biology and manufacturing, notably through the relations between land, food and population. From the grand nineteenth-century transformations of matter to systems ecology, the circulation of molecules through organic and inorganic compartments has posed the problem of maintaining identity in the face of flux and highlights the seductive ability of cyclic schemes to imply closure where no original state was in fact restored. More concerted attention to cycles and circulation will enrich analyses of the power of metaphors to naturalize understandings of life and their shaping by practical interests and political imaginations.

Was Tiepolo's wife affected by Graves' disease?

Tiepolo (1696-1770) was an Italian Rococo painter and printmaker, and is now considered to be one of the most important members of the 18th-century Venetian school. The muse that lent her face to Cleopatra and inspired many Tiepolo's works was his beloved wife, Maria Cecilia Guardi. Because of her appearance, we cannot rule out that she suffered from Graves' disease, an autoimmune condition that is characterized by goiter, exophthalmos and restlessness.

A 40 years journey with fish spermatozoa as companions as I personally experienced it

When, in the 1980s, I became interested in the spermatology of fish under the light microscope, active spermatozoa were only visible thanks to their head presenting a sort of "tremor." This situation was quite frustrating given the lack of possible information regarding the motor part called flagellum. We decided to apply simple technologies, including photography. Due to the high speed of the moving fish flagellum, the microscope illumination used a pulsed light strobe combined with a dark field microscope to record the flagellum image despite its small diameter (< 0.5 μm). Then came high-speed cinematographic microscopy up to 200 fps, as well as video cameras. At the end of the 1990s, an automatic moving object video tracking system began to be commercialized (CASA) with main advantages such as (a) a large number of cells tracked, which greatly improves statistics, (b) computer assistance allowing an automatic analysis that provides many motility parameters. Nevertheless, CASA systems are still unable to provide information about fish sperm flagella that move fast. During the 1990s, analog video camera technologies allowed acquisition of flagellum images with high resolution for detailed analysis. Since the 2000s, the use of high-speed video cameras allows the acquisition of images at a much higher resolution and frequency, up to 10,000 frames per second. Since it became possible to visualize the flagella in motion, a noble function was added to that of a propeller: that of a rudder with what a spermatozoon responds to specific signals delivered by the egg for its guidance. In the future, one can wish that an automatic flagella movement analyzer will become functional. This brief anthology puts forward the large amount of progress accomplished during past 40-year period about spermatozoa movement analysis, especially in fish.

Characteristics of Dietary Fatty Acids Isolated from Historic Dental Calculus of the 17th- and 18th-Century Inhabitants of the Subcarpathian Region (Poland)

Dental calculus analysis can be a valuable source of archaeological knowledge, since it preserves not only microbial and host biomolecules but also dietary and environmental debris, as well as metabolic products likely originating from dietary and craft activities. Here we described GC-MS analysis of a set of historic dental calculus samples from the front teeth of the mandibles of seven individuals found in 17th- and 18th-century graves in the city of Rzeszow, located in South-eastern Poland. We have found that only saturated fatty acids, which are characteristic for fats of animal origin, were present in the tested samples. Our preliminary results indicate that the diet of modern-period inhabitants of Rzeszow was rich in animal products, such as meat and dairy products.

Learning the Chymical Compromise: Paracelsian and Galenic Medicine in Marburg Disputations on Chymiatria

The chair of chymiatria created at the University of Marburg was among the earliest academic initiatives aiming to integrate chymistry into the medical curriculum. If its practical applications in pharmacy and its relationship with patronage have been examined by historians, the theoretical part of the chymiatria programme still remains to be explored. In the form of student disputations and dissertations held or presided over by Heinrich Petraeus, a professor of medicine at Marburg and Johannes Hartmann's son-in-law, "chymiatric" essays expounded various medical issues. Centred on pathology, therapy, and physiology, these theoretical explanations proposed a "hermetic-dogmatic" interpretation merging the views of Paracelsus and Galen. This article examines these disputations and their stance concerning the living body, sickness, and treatment, and how they shaped the status of chymistry as an art and a science on the verge of institutionalisation.

Protection against severe infectious disease in the past

Before the 20th 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.

That "Bulky Commodity, Tobacco"

Tobacco, like other popular commodities, both reflected the rhythms of early modern empires and contributed to them. People, goods, and ideas crossing the Atlantic Ocean often traveled as freight in vessels bound upon other business, and much of that was tobacco business. Using a variety of historical examples, the current article explores tobacco's economic, cultural, and labor-related worlds to show how one plant shaped institutions of human enslavement, altered colonial ecologies, offered new sensory possibilities, and ruined fortunes. Although now perhaps better known within medical contexts as a significant, preventable cause of death, tobacco as it is understood today is also a highly political, economic, and cultural product, characteristics that have shaped human relationships to the commodity over the centuries. The 17th and 18th centuries, for example, saw a dramatic rise in tobacco consumption in Europe alongside an influx of colonial natural products across the continent. The tobacco trade offered power and profit to some, exploitation and enslavement to others. It underwrote the rise of prominent merchant and political families while shaping the daily routines of countless enslaved men, women, and children tasked with growing the plant. Tobacco leaves also offered hopes of medical treatment and trustworthy business dealings, as well as a moment of respite on a long voyage. At every stage of its evolution into a global commodity, tobacco's meanings and roles changed, becoming more fully integrated into European empire and its structures of power and profit in the process.

Isaac Newton's 'De gravitatione et aequipondio fluidorum': its purpose in historical context

Few texts in the history of science and philosophy have achieved the level of interpretative indeterminacy as a short manuscript tract by Isaac Newton, known as 'De gravitatione'. On the basis of some new evidence, this article argues that it is an introductory fragment of some lectures on hydrostatics delivered in the of spring 1671. Taking seriously the possibility of a pedagogical purpose, it is then argued that the famous digression on space, far from articulating a sophisticated metaphysics that may have owed something to Henry More, was a simple piece of mixed-mathematical prolegomena designed to facilitate the subsequent geometrical argumentation. In this regard, Newton was doing the same as his mentor, Isaac Barrow, had done in his own mathematical lectures; both drew heavily on the explicitly anti-metaphysical approach of Pierre Gassendi. It is shown that More himself would have almost certainly opposed Newton's approach. The excesses of metaphysical readings of Newton's intentions are challenged; there is no warrant for reading the digression as directly relevant to the Principia.
