The catalogue of the Westhoff collection of Chinese materia medica (c. 1870): Evidence of interaction between a Chinese medicine practitioner and the Dutch in Indonesia.

ETHNOPHARMACOLOGICAL RELEVANCE: The Westhoff collection of Chinese materia medica (c. 1870) at the Utrecht University Museum in Utrecht, the Netherlands, contains an original, handwritten catalogue, which was putatively ascribed to a Chinese medicine practitioner. It provides a detailed record of the Chinese names, plant parts, preparations, and applications of the specimens contained in glass bottles, which probably reflects the physician's personal interpretation of Chinese medicine in Indonesia at the end of the 19th century. Such individual catalogues can reveal historical changes and regional variations in the use of traditional Chinese medicine, which can lead to a better understanding of the history and development of this field. AIM OF THE STUDY: We addressed the following questions: 1) What are the contents of the Westhoff catalogue? 2) What medicinal preparations and applications were recorded in the catalogue, and which ones are dominant? 3) How similar is the use of Chinese materia medica in Westhoff catalogue compared to the modern Chinese Pharmacopeia? 4) What other specific information is contained in the Westhoff catalogue? MATERIALS AND METHODS: The catalogue had been digitized previously, and all handwritten Dutch text has been transcribed and translated into English. The information for each entry was summarized and analyzed, the medicinal applications were compared to modern Chinese pharmacopeia or other monographs on Chinese materia medica. RESULTS: The catalogue contains 436 entries, for which 395 corresponding specimens still exist in the Westhoff collection of Chinese materia medica. Each entry contains a serial number, a Chinese name, a phonetic Dutch transcription of the Chinese name, a description of the plant, animal, or mineral origin of the medicinal product, the preparation method, and the medical indication for which it should be used. The dominant preparation method is decoction (79% of the entries). The most frequently mentioned applications are fever, skin diseases, strengthening and wounds. Around 80% of the medicinal applications in the catalogue were also listed for the same CMM in modern monographs. The catalogue also sheds light on typical characteristics of popular medicine, their geographic origin, and social aspects of traditional Chinese medicine in Indonesia around 1870. CONCLUSIONS: The Westhoff catalogue is a valuable record of Chinese materia medica and its practice in a specific time and space. It reflects an individual physician's interpretation of Chinese medicine, shows the difficulties in the interpretation of cultural-bound health issues between the Dutch and the Chinese, and provides evidence that traditional Chinese medicine spread not only in East Asia but also to the distant Western world.

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

Yang ke xuan cui («¼) 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 ().

Einkorn genomics sheds light on history of the oldest domesticated wheat.

Einkorn (Triticum monococcum) was the first domesticated wheat species, and was central to the birth of agriculture and the Neolithic Revolution in the Fertile Crescent around 10,000 years ago1,2. Here we generate and analyse 5.2-Gb genome assemblies for wild and domesticated einkorn, including completely assembled centromeres. Einkorn centromeres are highly dynamic, showing evidence of ancient and recent centromere shifts caused by structural rearrangements. Whole-genome sequencing analysis of a diversity panel uncovered the population structure and evolutionary history of einkorn, revealing complex patterns of hybridizations and introgressions after the dispersal of domesticated einkorn from the Fertile Crescent. We also show that around 1% of the modern bread wheat (Triticum aestivum) A subgenome originates from einkorn. These resources and findings highlight the history of einkorn evolution and provide a basis to accelerate the genomics-assisted improvement of einkorn and bread wheat.

From Passos the Indian to Doctor Chernoviz: experiments to cure leprosy in nineteenth-century Pará. / Do índio Passos ao doutor Chernoviz: experiências de cura da lepra no Pará do século XIX.

This article analyzes an experiment to cure leprosy using the assacu plant (Hura crepitans L.) conducted in Santarém, Pará, in 1847, by an Indigenous man named Antonio Vieira dos Passos. The experiment was later repeated in other Brazilian provinces and abroad. This article establishes relationships between medical practices in other parts of the country while focusing on the dialog between official and Indigenous medicine. Newspaper articles and official documents of the time show that Indigenous knowledge of medicinal plants was widely recognized and utilized by physicians wishing to incorporate it into the official therapeutic repertoire.

O artigo analisa uma experiência de cura da lepra com assacu (Hura crepitans L.), realizada em Santarém, Pará, em 1847, por um indígena chamado Antonio Vieira dos Passos. A experiência passou a ser realizada nas demais províncias do Brasil e também no exterior. Por essa razão, o artigo estabelece relações com práticas médicas realizadas em outras partes do país, tendo como foco o diálogo entre a medicina oficial e a medicina indígena. A análise de matérias de jornais e documentos oficiais revelou que os saberes indígenas sobre o uso de plantas medicinais eram amplamente reconhecidos e utilizados pelos médicos com a intenção de incorporá-los em seu repertório terapêutico.

Forgotten Pediatrics: 8 Disturbing Windows on the Past.

The 75 years since Pediatrics was first published has witnessed an explosion of the scientific knowledge base informing child health. Yet, the path leading to the present has not been linear. We examine several articles that illustrate some of the unexpected twists and turns that have characterized our specialty's history. We hope that it will provide a reminder of the ever-changing nature of scientific knowledge and the need to continually re-evaluate how our own cultural assumptions shape medical practice.

A genetic history of continuity and mobility in the Iron Age central Mediterranean.

The Iron Age was a dynamic period in central Mediterranean history, with the expansion of Greek and Phoenician colonies and the growth of Carthage into the dominant maritime power of the Mediterranean. These events were facilitated by the ease of long-distance travel following major advances in seafaring. We know from the archaeological record that trade goods and materials were moving across great distances in unprecedented quantities, but it is unclear how these patterns correlate with human mobility. Here, to investigate population mobility and interactions directly, we sequenced the genomes of 30 ancient individuals from coastal cities around the central Mediterranean, in Tunisia, Sardinia and central Italy. We observe a meaningful contribution of autochthonous populations, as well as highly heterogeneous ancestry including many individuals with non-local ancestries from other parts of the Mediterranean region. These results highlight both the role of local populations and the extreme interconnectedness of populations in the Iron Age Mediterranean. By studying these trans-Mediterranean neighbours together, we explore the complex interplay between local continuity and mobility that shaped the Iron Age societies of the central Mediterranean.

Genomic inference of a severe human bottleneck during the Early to Middle Pleistocene transition.

Population size history is essential for studying human evolution. However, ancient population size history during the Pleistocene is notoriously difficult to unravel. In this study, we developed a fast infinitesimal time coalescent process (FitCoal) to circumvent this difficulty and calculated the composite likelihood for present-day human genomic sequences of 3154 individuals. Results showed that human ancestors went through a severe population bottleneck with about 1280 breeding individuals between around 930,000 and 813,000 years ago. The bottleneck lasted for about 117,000 years and brought human ancestors close to extinction. This bottleneck is congruent with a substantial chronological gap in the available African and Eurasian fossil record. Our results provide new insights into our ancestry and suggest a coincident speciation event.

Revealing the secrets of a 2900-year-old clay brick, discovering a time capsule of ancient DNA.

The recent development of techniques to sequence ancient DNA has provided valuable insights into the civilisations that came before us. However, the full potential of these methods has yet to be realised. We extracted ancient DNA from a recently exposed fracture surface of a clay brick deriving from the palace of king Ashurnasirpal II (883-859 BCE) in Nimrud, Iraq. We detected 34 unique taxonomic groups of plants. With this research we have made the pioneering discovery that ancient DNA, effectively protected from contamination inside a mass of clay, can successfully be extracted from a 2900-year-old clay brick. We encourage future research into this subject, as the scientific prospects for this approach are substantial, potentially leading to a deeper understanding of ancient and lost civilisations.

[Understanding the mode of transmission of malaria agents: an astonishing series of hypotheses, observations, research and controversy]. / Compréhension du mode de transmission des agents du paludisme: une étonnante suite d'hypothèses, d'observations, de recherches et de controverses.

In 1880, Laveran observed the causative agent of malaria. As early as 1884, he considered that mosquitoes could be responsible for the transmission of haematozoa, a hypothesis which resulted from the observation and reflection of an informed hygienist. But, as Laveran himself said, "the opinion that I defended was considered by most observers to be highly unlikely".Nearly 15 years after the discovery of the haematozoan, the elucidation of the mechanism of transmission still proved difficult to establish. A link with the existence of swamps had been established a long time before, but the true mode of transmission remained a mystery until the end of the 19th century. The implication, by Manson in 1877, of mosquitoes in the cycle of the Bancroftian filaria, then other observations of the same order, ended up attracting the attention of malariologists. Laveran himself was quickly convinced of the role of mosquitoes in carrying out the natural cycle and propagating Plasmodium, but this theory had as many detractors as supporters.In 1897, Ross showed the presence of oocysts on the stomach of mosquitoes previously gorged on a malaria patient, then in 1898, of sporozoites of bird plasmodia in mosquitoes. He was convinced that, through their bite, these insects were responsible for the transmission of human malaria agents, without being able to prove it. The results obtained by Ross were immediately confirmed in Italy by Grassi and his collaborators who, in November 1898, described the stages of Plasmodium in man and, through various experiments carried out in collaboration with British researchers, showed the role of Anopheles, a result far from being accepted by all. Skepticism persisted for a long time.An excellent protozoologist, Laveran was not an entomologist. He was however among the first defenders of the anopheline theory. He worked extensively on establishing the relationships between Anopheles mosquitoes and malaria and took a close interest in the environmental conditions of the transmission. In his mind, malaria fever should henceforth be classified as a preventable disease. An era of hope thus dawned: malaria prophylaxis, based on fight against mosquitoes, could begin.

[Laveran and the French Academy of Medicine]. / Laveran et l'Académie nationale de médecine.

In November 1880, Alphonse Laveran, stationed at the Constantine military hospital, addressed to the Academy of Medicine a "Note on a new parasite found in the blood of several patients with malaria fever". Léon Colin, professor at the Val-de-Grâce school, is the rapporteur, but he is not convinced by these observations, nor by two additional notes sent by Laveran in December 1880 and October 1881. This skepticism is shared by other academicians such as Joseph Laboulbène and Émile Duclaux.Twelve years will be necessary for Laveran to overcome the disbelief of the French scientific community. Three fundamental books donated to the Academy testify to the tenacity with which he gradually succeeded in convincing most of his colleagues: Traité des fièvres palustres avec la description des microbes du paludisme in 1884, Des hématozoaires du paludisme in 1887, and Du paludisme et de son hématozoaire in 1891.Laveran was elected to the Academy of Medicine on December 26, 1893. His resignation from the Military Health Corps enabled him to participate assiduously in meetings and to intervene in debates concerning infectious and tropical diseases, hygiene and prophylaxis. Obtaining the Nobel Prize in 1907 for his work on malaria, trypanosomiasis and colonial diseases crowned his work while honoring the Academy. Laveran was elected vice-president for the year 1919 and president for 1920, the year of the centenary of the Academy, the celebration of which he organized to the detriment of his health. He died two years later, having fulfilled his duty to the end of his strength.

[Laveran and the eradication of malaria in Corsica]. / Laveran et l'éradication du paludisme en Corse.

The observation of miasmas and fevers was attested in the region of Biguglia, South of Bastia, in 1499, confirmed during the 17th century. Drainage works on the eastern coast were started in 1770, abandoned during the revolutionary period, restarted under the Second Empire, with few results on the endemic. Thus in 1875, 80% of the inhabitants of the eastern plain were considered on their appearance to suffer malaria. The rural population was miserable, the mortality high. However, it was not possible to distinguish the responsibility of malaria among the other fevers.In 1899 and following years, A. Laveran was in Corsica. He confirmed the presence of Anopheles in the localities where malaria was present. He encouraged the creation in Bastia in 1902 of the Corsican League against Malaria and he chaired it. The actions of this League were based on the fight against the larvae by chemical destruction, on the use of mosquito nets and on massive and free preventive "quininisation". A sanitation and development law for Corsica was passed in 1911. Initial results were observed, confirmed by Léger and Arlo (1913) [6]. After WW1, the activities started again, in particular by Sergent and Sergent. An antimalarial application station, subsidized by the Rockefeller Foundation, was created in Bastia in 1925, supported by the laboratory of parasitology of the Faculty of Medicine of Paris. Plasmodium falciparum was predominant, transmitted essentially by Anopheles labranchiae of the maculipennis complex, up to an altitude of 500 m. The role of population displacements, linked to pastoral practices, the absence of stables and therefore of zoonotic deviation of anopheles were underlined.The liberation of Corsica in October 1943 allowed the installation by the American army of numerous airfields on the eastern plain. An intense local mosquito control by DDT was then carried out, impressing the population. However, malaria prospered on the island with an acme of indices in 1947. From 1948, campaigns of spraying insecticide against adults, chemical control of larvae or use of larvivorous fish, treatment of patients in dispensaries led to very good results. Since 1953, malaria transmission is interrupted in Corsica excepted 30 indigenous cases in 1970-71. Currently, the situation in Corsica of an anophelism without malaria is considered to be under control with a low risk of resumption of a localized transmission.

[In the wake of Alphonse Laveran]. / Dans le sillage d'Alphonse Laveran.

Alphonse Laveran (Nobel Prize 1907) played a pioneering role in discovering the causative agent of malaria, a disease that has existed since time immemorial, and long emblematic of the miasma theory until the end of the 19th century. In 1880, this unknown military doctor discovered the role of a hematazoan in malaria, designated Plasmodium. This was the first protozoan to be discovered in an infectious disease, at a time when bacteria were mainly suspected. This major discovery led to the identification of the role of mosquitoes in the spread of malaria by Ronald Ross (Nobel Prize 1902) and Battista Grassi. The recurrence of malaria attacks over many years was for a long time an enigma only solved after the Second World War by the discovery of the exo-erythrocytic cycle of Plasmodium. Progress was then made in treatment, from cinchona bark, quinine and chloroquine, to the recent discovery of artemisinin in 1972 by the Chinese researcher Tu Youyou (Nobel Prize 2015).
