  1. [The roots of Cha and Gambir]
    Sugiyama S

    PMID: 17152831
    This article attempts to trace the origin of tea. The author believes the ancient Chinese tea, "chia", is either Jicha (water extract from the pith of Acacia catechu that grows naturally in the mountainous border between the Yunnan province of China and southern Asian countries) or Jicha-Kagikazura (water extract from the young branches and leaves of Uncaris gambir, originally found in India/Sri Lanka). Both were pulverized after being kiln-dried and then mixed with water to produce a thick suspension, or tea. Although the drink is bitter and has an astringent property, it has a particular flavor with a refreshing after-taste. Its components with medicinal properties include tannin, catechin, and various flavonoids, making us believe it was worthwhile for the people at the time to consume the drink regularly. Generally speaking, tea cultivation in China flourished south of the Yangzi Jiang River including the present Zhejiang and Anhui provinces. Depending on the regions, there were words for tea in various languages, including the names of places where particular teas were grown. In addition to the names that appear in the famous Chajing book, it is interesting to note Da Fang pronounced tea as "TAH". Because the area south of the Yangzi Jiang has traditionally been active in foreign trade since the ancient and middle ages. People in this region consumed various foreign originated teas as well. This included Gambir, which was introduced to southern Asia (including present Malaysia and Indonesia) and was consumed as an herbal tea under names such as Guo Luo or Ju Luo teas. Paan, from India, also uses Gambir paste and was a popular chewing refreshment to prevent diseases caused by miasma as well as to keep one's mouth clean. The name A-sen-yaku used in Japan was taken from the plant name Acasia, and Gambir was used to dye Buddhist monks' Ke-Ra bags to a blackish yellow color. The Daikanwa dictionary states the Ra in the name, which means thin silk, was later replaced with "A". The official name for Ji-cha [Er Cha] in modern China is "Gaiji-cha", [Hal-Er Cha], which comes from the name of a variety of tea made by the Ai-Ni tribal subgroup of the ethnic Ha-Ni in Yunnan province. The [see character in text] character is pronounced "ni", which is a homophony of [character in text]. Based on these facts, "Ai-Ni" should be considered the same as "Hai-Ni". Because the ethnic groups in Yunnan province used primitive and tough tea leaves, which were eaten instead of being infused in water, the leaves were first fermented by being buried in the ground. Even today, people of these ethnic groups prefer fungus-fermented black tea with a particular flavor. In contrast, the ethnic Hans used and still use improved and softer young shoots of tea leaves to prepare mainly green tea. It has recently been discovered that Acapsia, as well as Gambir, has anti-oxidant properties, and that consumption over time is effective against many lifestyle-related adult diseases. It may be well worthwhile to cast fresh light upon ancient tea drinking customs.

    PMID: 11613284
    Among the issues of medical exchanges, medicaments are more often encountered than medical issues, based on ancient Chinese literatures, early in the Han-Jin Dynasties, Thailand, Malaysia, Indonesia, and Brunei had exchanges with China, also in Sui-Tang Dynasties. In the Song-Yuan Dynasties, ancient Singapore and the Philippines also incorporated in exchanges of medicament and goods. In the Ming-Qing dynasties, these 6 Asian countries had even more close contact with China, especially in trades and medical exchanges among the masses, carried out in a large scale thus, promoting the advent and development of TCM in Asiana Regions.

  3. Fulltext The significance of pyrogenic polycyclic aromatic hydrocarbons in Borneo peat core for the reconstruction of fire history
    Kong SR, Yamamoto M, Shaari H, Hayashi R, Seki O, Mohd Tahir N, et al.
    PLoS One, 2021;16(9):e0256853.
    PMID: 34495997 DOI: 10.1371/journal.pone.0256853
    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.

  4. The prehistoric peopling of Southeast Asia
    McColl H, Racimo F, Vinner L, Demeter F, Gakuhari T, Moreno-Mayar JV, et al.
    Science, 2018 07 06;361(6397):88-92.
    PMID: 29976827 DOI: 10.1126/science.aat3628
    The human occupation history of Southeast Asia (SEA) remains heavily debated. Current evidence suggests that SEA was occupied by Hòabìnhian hunter-gatherers until ~4000 years ago, when farming economies developed and expanded, restricting foraging groups to remote habitats. Some argue that agricultural development was indigenous; others favor the "two-layer" hypothesis that posits a southward expansion of farmers giving rise to present-day Southeast Asian genetic diversity. By sequencing 26 ancient human genomes (25 from SEA, 1 Japanese Jōmon), we show that neither interpretation fits the complexity of Southeast Asian history: Both Hòabìnhian hunter-gatherers and East Asian farmers contributed to current Southeast Asian diversity, with further migrations affecting island SEA and Vietnam. Our results help resolve one of the long-standing controversies in Southeast Asian prehistory.

    PMID: 1787417
    Belief in a golden age has provided mankind with solace in times of despair and with élan during the expansive periods of history. Dreamers imagine the golden age in the remote past, in paradise lost, free from toil and grief. Optimists put their faith in the future and believe that mankind, Prometheus-like, will master the arts of life through power and knowledge. Thus, the golden age means different things to different men, but the very belief in its existence implies the conviction that perfect health and happiness are birthrights of men. Yet, in reality, complete freedom from disease and from struggle is almost incompatible with the process of living.

  7. The 1996 Runme Shaw Memorial Lecture: malaria--past, present and future
    Warrell DA
    Ann Acad Med Singap, 1997 May;26(3):380-7.
    PMID: 9285035
    Falciparum malaria may have infected Homo sapiens (and perhaps H erectus) in the Asia Pacific region for more than 100,000 years. This estimate is based on the gene frequency of alpha-thalassaemia, the protection it affords against falciparum malaria and assumptions of untreated mortality from the infection. Up until the end of the 19th century, there was a high mortality from malaria in the coastal parts of Malaya, but the malaria control campaign, begun in 1901 at Klang, was described by Sir Ronald Ross as the first successful antimalarial work in the (then) British Empire. This was extended to Singapore in 1911. When the Far Eastern Association of Tropical Medicine held its Fifth Biennial Congress in Singapore in 1923, malaria was still a major killing disease in parts of Malaya and Sarawak. The mechanism of life-threatening malaria involves cytoadherence of parasitised erythrocytes in microvascular beds, a process enhanced by the products of macrophage activation induced by malarial pyrogen. Improvements in the chemotherapy of life-threatening falciparum malaria with chloroquine and quinine have been countered by the emergence of resistant strains. Artemisinin derivatives may become the treatment of choice during the coming decade. Apart from traditional anti-mosquito methods, control of malaria now involves the use of insecticide-impregnated bed nets, new entomological strategies, including genetic manipulation of mosquitoes and selective chemoprophylaxis. Antigenic diversity and antigenic variation of the malaria parasite have so far defeated attempts to produce an effective vaccine.

    PMID: 24595576
    Limonia acidissima or Hesperethusa crenulata is a common tree in Southeast Asia. It is indigenous to the Republic of Myanmar (formerly Burma) as well as India, Sri Lanka, Java, and Pakistan. In English, the common names for Limonia acidissima are sandalwood, wood-apple, elephant-apple, monkey fruit, and curd fruit tree. The plant has a number of different names in different languages including bal or bael in Assamese, bael in Bengali, kaitha in Hindi, belingai in Malaysia, and thanaka in Burmese. Unique to the Burmese people, thanaka has been used as a cosmetic product for over 2000 years. Mention of thanaka has been traced back to ancient Burmese lyrics, and relics of equipment used by ancient royalty to grind thanaka can be found in museums.

  9. Single, rapid coastal settlement of Asia revealed by analysis of complete mitochondrial genomes
    Macaulay V, Hill C, Achilli A, Rengo C, Clarke D, Meehan W, et al.
    Science, 2005 May 13;308(5724):1034-6.
    PMID: 15890885
    A recent dispersal of modern humans out of Africa is now widely accepted, but the routes taken across Eurasia are still disputed. We show that mitochondrial DNA variation in isolated "relict" populations in southeast Asia supports the view that there was only a single dispersal from Africa, most likely via a southern coastal route, through India and onward into southeast Asia and Australasia. There was an early offshoot, leading ultimately to the settlement of the Near East and Europe, but the main dispersal from India to Australia approximately 65,000 years ago was rapid, most likely taking only a few thousand years.

  10. Revisiting Notechis scutatus venom: on shotgun proteomics and neutralization by the "bivalent" Sea Snake Antivenom
    Tan CH, Tan KY, Tan NH
    J Proteomics, 2016 07 20;144:33-8.
    PMID: 27282922 DOI: 10.1016/j.jprot.2016.06.004
    Recent advances in proteomics enable deep profiling of the compositional details of snake venoms for improved understanding on envenomation pathophysiology and immunological neutralization. In this study, the venom of Australian tiger snake (Notechis scutatus) was trypsin-digested in solution and subjected to nano-ESI-LCMS/MS. Applying a relative quantitative proteomic approach, the findings revealed a proteome comprising 42 toxin subtypes clustered into 12 protein families. Phospholipases A2 constitute the most abundant toxins (74.5% of total venom proteins) followed by Kunitz serine protease inhibitors (6.9%), snake venom serine proteases (5.9%), alpha-neurotoxins (5.6%) and several toxins of lower abundance. The proteome correlates with N. scutatus envenoming effects including pre-synaptic and post-synaptic neurotoxicity and consumptive coagulopathy. The venom is highly lethal in mice (intravenous median lethal dose=0.09μg/g). BioCSL Sea Snake Antivenom, raised against the venoms of beaked sea snake (Hydrophis schistosus) and N. scutatus (added for enhanced immunogenicity), neutralized the lethal effect of N. scutatus venom (potency=2.95mg/ml) much more effectively than the targeted H.schistosus venom (potency=0.48mg/ml). The combined venom immunogen may have improved the neutralization against phospholipases A2 which are abundant in both venoms, but not short-neurotoxins which are predominant only in H. schistosus venom.

    SIGNIFICANCE: A shotgun proteomic approach adopted in this study revealed the compositional details of the venom of common tiger snake from Australia, Notechis scutatus. The proteomic findings provided additional information on the relative abundances of toxins and the detection of proteins of minor expression unreported previously. The potent lethal effect of the venom was neutralized by bioCSL Sea Snake Antivenom, an anticipated finding due to the fact that the Sea Snake Antivenom is actually bivalent in nature, being raised against a mix of venoms of the beaked sea snake (Hydrophis schistosus) and N. scutatus. However, it is surprising to note that bioCSL Sea Snake Antivenom neutralized N. scutatus venom much more effectively compared to the targeted sea snake venom by a marked difference in potency of approximately 6-fold. This phenomenon may be explained by the main difference in the proteomes of the two venoms, where H. schistosus venom is dominated by short-neurotoxins in high abundance - this is a poorly immunogenic toxin group that has been increasingly recognized in the venoms of a few cobras. Further investigations should be directed toward strategies to improve the neutralization of short-neurotoxins, in line with the envisioned production of an effective pan-regional elapid antivenom.

  12. Phylogeny, historical biogeography, and diversification of angiosperm order Ericales suggest ancient Neotropical and East Asian connections
    Rose JP, Kleist TJ, Löfstrand SD, Drew BT, Schönenberger J, Sytsma KJ
    Mol Phylogenet Evol, 2018 05;122:59-79.
    PMID: 29410353 DOI: 10.1016/j.ympev.2018.01.014
    Inferring interfamilial relationships within the eudicot order Ericales has remained one of the more recalcitrant problems in angiosperm phylogenetics, likely due to a rapid, ancient radiation. As a result, no comprehensive time-calibrated tree or biogeographical analysis of the order has been published. Here, we elucidate phylogenetic relationships within the order and then conduct time-dependent biogeographical and diversification analyses by using a taxon and locus-rich supermatrix approach on one-third of the extant species diversity calibrated with 23 macrofossils and two secondary calibration points. Our results corroborate previous studies and also suggest several new but poorly supported relationships. Newly suggested relationships are: (1) holoparasitic Mitrastemonaceae is sister to Lecythidaceae, (2) the clade formed by Mitrastemonaceae + Lecythidaceae is sister to Ericales excluding balsaminoids, (3) Theaceae is sister to the styracoids + sarracenioids + ericoids, and (4) subfamilial relationships with Ericaceae suggest that Arbutoideae is sister to Monotropoideae and Pyroloideae is sister to all subfamilies excluding Arbutoideae, Enkianthoideae, and Monotropoideae. Our results indicate Ericales began to diversify 110 Mya, within Indo-Malaysia and the Neotropics, with exchange between the two areas and expansion out of Indo-Malaysia becoming an important area in shaping the extant diversity of many families. Rapid cladogenesis occurred along the backbone of the order between 104 and 106 Mya. Jump dispersal is important within the order in the last 30 My, but vicariance is the most important cladogenetic driver of disjunctions at deeper levels of the phylogeny. We detect between 69 and 81 shifts in speciation rate throughout the order, the vast majority of which occurred within the last 30 My. We propose that range shifting may be responsible for older shifts in speciation rate, but more recent shifts may be better explained by morphological innovation.

  13. Palaeogenomic insights into the origins of French grapevine diversity
    Ramos-Madrigal J, Runge AKW, Bouby L, Lacombe T, Samaniego Castruita JA, Adam-Blondon AF, et al.

    The Eurasian grapevine (Vitis vinifera) has long been important for wine production as well as being a food source. Despite being clonally propagated, modern cultivars exhibit great morphological and genetic diversity, with thousands of varieties described in historic and contemporaneous records. Through historical accounts, some varieties can be traced to the Middle Ages, but the genetic relationships between ancient and modern vines remain unknown. We present target-enriched genome-wide sequencing data from 28 archaeological grape seeds dating to the Iron Age, Roman era and medieval period. When compared with domesticated and wild accessions, we found that the archaeological samples were closely related to western European cultivars used for winemaking today. We identified seeds with identical genetic signatures present at different Roman sites, as well as seeds sharing parent-offspring relationships with varieties grown today. Furthermore, we discovered that one seed dated to ~1100 CE was a genetic match to 'Savagnin Blanc', providing evidence for 900 years of uninterrupted vegetative propagation.

    PMID: 23835719 DOI: 10.1016/S2221-1691(13)60105-7
    The divine tree neem (Azadirachta indica) is mainly cultivated in the Indian subcontinent. Neem has been used extensively by humankind to treat various ailments before the availability of written records which recorded the beginning of history. The world health organization estimates that 80% of the population living in the developing countries relies exclusively on traditional medicine for their primary health care. More than half of the world's population still relies entirely on plants for medicines, and plants supply the active ingredients of most traditional medical products. The review shows the neem has been used by humankind to treat various ailments from prehistory to contemporary.

  15. Medicine has always been "Modern" and "Scientific" from ancient times to the present day
    Teppone M
    J Integr Med, 2019 Jul;17(4):229-237.
    PMID: 30967348 DOI: 10.1016/j.joim.2019.03.008
    Throughout human history, doctors and healers have gathered and refined the knowledge inherited from the previous generations. Different methods of effective therapy have been designed during various historical periods; when each was developed, it was considered "modern scientific medicine" for their time. Mankind has gone through natural and social disasters and survived; hence, history has proved there was no time when medical knowledge was erroneous or ineffective. Classic medicine has grown to be divided into narrow, specialized branches, causing it to lose its holistic approach and general view on health, sickness and therapeutic methods. Many of traditional medicine's effective methods have been forgotten and removed from the mainstream medicine. It would be good for modern medical education to incorporate the general knowledge of historically effective therapeutic modalities and study practical cases. Medical students should be taught how to choose a "good method" or "good medicine" independent of when that method or remedy was discovered. However, he has to keep in mind the primary goal of medicine: "I will use treatment to help the sick according to my ability and judgment…"(from Hippocratic Oath).

  17. Is Hinduism ambivalent about suicide?
    Vijayakumar L, John S
    Int J Soc Psychiatry, 2018 08;64(5):443-449.
    PMID: 29783869 DOI: 10.1177/0020764018777523
    BACKGROUND: Hinduism is one of the oldest religions in the world and has over 1.1 billion adherents comprising about 16% of the global population living mainly in India and Nepal. The stand of Hinduism on suicide has been ambiguous through the ages, on one hand, condemning general suicides, while condoning religious suicides on the other. This ambiguity is reflected in contemporary India and among the Indian diaspora.

    AIMS: To examine the stand of Hinduism as a religion in the context of suicide.

    METHOD: A selected review of literature covering the major Hindu religious texts, cultural practices and suicide.

    RESULTS: People who follow Hinduism have a suicide rate of about 21 per 100,000 population compared to the global average of 11.4. Hindu countries have higher rates of suicide compared to Islamic and Christian countries, but these rates are lower when compared to Atheist and Buddhist countries. This is reflected in the Indian diaspora as well with reports from Fiji, the Caribbean, Malaysia and the United Kingdom, indicating that suicide was disproportionately high among those of Indian origin. However, a strong faith in Hinduism acts as protective factor. The Hindu belief in karma fosters a sense of acceptance of the vicissitudes of life with equanimity, and the belief in the cycle of births and deaths renders suicide meaningless, as one's soul continues after death. Their religious beliefs makes the Hindus tolerate and accept hardships and calamities stoically.

    CONCLUSION: In certain situations, the Hindu religion acts as a protective factor, whereas at other times, it may increase the risk of suicide. It is important to understand these different nuances in the Hindu religion in formulating a culturally appropriate suicide prevention strategy.

  18. Fulltext Genomic insights into the conservation status of the world's last remaining Sumatran rhinoceros populations
    von Seth J, Dussex N, Díez-Del-Molino D, van der Valk T, Kutschera VE, Kierczak M, et al.
    Nat Commun, 2021 Apr 26;12(1):2393.
    PMID: 33896938 DOI: 10.1038/s41467-021-22386-8
    Small populations are often exposed to high inbreeding and mutational load that can increase the risk of extinction. The Sumatran rhinoceros was widespread in Southeast Asia, but is now restricted to small and isolated populations on Sumatra and Borneo, and most likely extinct on the Malay Peninsula. Here, we analyse 5 historical and 16 modern genomes from these populations to investigate the genomic consequences of the recent decline, such as increased inbreeding and mutational load. We find that the Malay Peninsula population experienced increased inbreeding shortly before extirpation, which possibly was accompanied by purging. The populations on Sumatra and Borneo instead show low inbreeding, but high mutational load. The currently small population sizes may thus in the near future lead to inbreeding depression. Moreover, we find little evidence for differences in local adaptation among populations, suggesting that future inbreeding depression could potentially be mitigated by assisted gene flow among populations.

  19. Fulltext Genome of a middle Holocene hunter-gatherer from Wallacea
    Carlhoff S, Duli A, Nägele K, Nur M, Skov L, Sumantri I, et al.
    Nature, 2021 Aug;596(7873):543-547.
    PMID: 34433944 DOI: 10.1038/s41586-021-03823-6
    Much remains unknown about the population history of early modern humans in southeast Asia, where the archaeological record is sparse and the tropical climate is inimical to the preservation of ancient human DNA1. So far, only two low-coverage pre-Neolithic human genomes have been sequenced from this region. Both are from mainland Hòabìnhian hunter-gatherer sites: Pha Faen in Laos, dated to 7939-7751 calibrated years before present (yr cal BP; present taken as AD 1950), and Gua Cha in Malaysia (4.4-4.2 kyr cal BP)1. Here we report, to our knowledge, the first ancient human genome from Wallacea, the oceanic island zone between the Sunda Shelf (comprising mainland southeast Asia and the continental islands of western Indonesia) and Pleistocene Sahul (Australia-New Guinea). We extracted DNA from the petrous bone of a young female hunter-gatherer buried 7.3-7.2 kyr cal BP at the limestone cave of Leang Panninge2 in South Sulawesi, Indonesia. Genetic analyses show that this pre-Neolithic forager, who is associated with the 'Toalean' technocomplex3,4, shares most genetic drift and morphological similarities with present-day Papuan and Indigenous Australian groups, yet represents a previously unknown divergent human lineage that branched off around the time of the split between these populations approximately 37,000 years ago5. We also describe Denisovan and deep Asian-related ancestries in the Leang Panninge genome, and infer their large-scale displacement from the region today.

  20. Genetic, historical and linguistic perspectives on the origin of the Kelantanese Malays
    Loo KW, Gan SH
    Gene, 2014 Jul 15;545(1):1-4.
    PMID: 24815047 DOI: 10.1016/j.gene.2014.05.016
    The Kelantanese Malays who resided in the remote northeastern regions of the Malay Peninsula in the Kelantan state are believed to have a unique genetic signature. The objective of this review is to analyze the populational sub-structure of the Kelantanese Malays from historical, genetic and linguistic perspectives. Historical data suggest that the Semang were composed of the Jahai, Bateq and Kensiu sub-tribes, whereas the Senoi were composed of only the Temiar sub-tribe. The Mendriq sub-tribe is believed to be the first group of aborigines to land in Kelantan. Subsequently, genetic analysis showed that the Kelantanese Malays are an independent clade at the base of the phylogenetic tree and contain genetic material similar to that of the Semang, specifically the Jahai and the Kensiu sub-tribes. The genetic data are supported by the fact that the Aslian language, a branch of the Austroasiatic languages that is widely spoken by the Semang, was potentially transmitted through agricultural activities. However, the potential limitation of this mini-review is the lack of primary reliable sources covering the historical, linguistic and genetic features of the Kelantanese Malays.
