The origins and spread of domestic horses from the Western Eurasian steppes

This is the final version. Available on open access from Nature Research via the DOI in this recordData availability: All collapsed and paired-end sequence data for samples sequenced in this study are available in compressed fastq format through the European Nucleotide Archive under accession number PRJEB44430, together with rescaled and trimmed bam sequence alignments against both the nuclear and mitochondrial horse reference genomes. Previously published ancient data used in this study are available under accession numbers PRJEB7537, PRJEB10098, PRJEB10854, PRJEB22390 and PRJEB31613, and detailed in Supplementary Table 1. The genomes of ten modern horses, publicly available, were also accessed as indicated in their corresponding original publications57,61,85-87.NOTE: see the published version available via the DOI in this record for the full list of authorsDomestication of horses fundamentally transformed long-range mobility and warfare. However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of bridling, milking and corralling at Botai, Central Asia around 3500 BC. Other longstanding candidate regions for horse domestication, such as Iberia and Anatolia, have also recently been challenged. Thus, the genetic, geographic and temporal origins of modern domestic horses have remained unknown. Here we pinpoint the Western Eurasian steppes, especially the lower Volga-Don region, as the homeland of modern domestic horses. Furthermore, we map the population changes accompanying domestication from 273 ancient horse genomes. This reveals that modern domestic horses ultimately replaced almost all other local populations as they expanded rapidly across Eurasia from about 2000 BC, synchronously with equestrian material culture, including Sintashta spoke-wheeled chariots. We find that equestrianism involved strong selection for critical locomotor and behavioural adaptations at the GSDMC and ZFPM1 genes. Our results reject the commonly held association between horseback riding and the massive expansion of Yamnaya steppe pastoralists into Europe around 3000 BC driving the spread of Indo-European languages. This contrasts with the scenario in Asia where Indo-Iranian languages, chariots and horses spread together, following the early second millennium BC Sintashta culture

Современный взгляд на проблему постхолецистэктомического синдрома (по материалам Экспертного совета, состоявшегося 4 мая 2019 г. в городе Алматы, Казахстан)

Gallstone disease is revealed in 10–20% of the population with a clear tendency to affect the younger population. In a clinically manifested course, cholecystectomy remains the treatment of choice. Symptoms and signs persist or even become more severe after gallbladder surgery in 10-15% of cases (“postcholecystectomy syndrome”). Postcholecystectomy syndrome includes heterogeneous disorders of liver, pancreas, duodenum, sphincter of Oddi, etc. that can be associated with errors or negative consequences of surgical intervention. Often, symptoms may persist because of previously unrecognized chronic diseases of neighboring organs. The spectrum of effective conservative measures is rather limited. The Advisory Board was held on May 4, 2019, in Almaty (Kazakhstan) to re-estimate the definitions and categories related to the issue of the postcholecystectomy syndrome and to develop the diagnostic and treatment algorithm for patients with the postcholecystectomy dysfunction of the sphincter of Oddi. The statements discussed by the interdisciplinary team of gastroenterologists and surgeons were addressed to general practitioners, therapists, gastroenterologists, and surgeons. The Advisory Board emphasized that organic and functional biliary diseases manifest mainly by biliary pain, main characteristics of which were defined in the Rome IV consensus based on the statistical analysis of a large pool of clinical data. For a more accurate bile duct system assessment and the exclusion of cholelithiasis, the examination algorithm was proposed, which included abdominal ultrasound investigation, endoscopic ultrasound investigation of the pancreatobiliary area, and magnetic resonance cholangiopancreatography. Diagnostic algorithm for differentiation of functional biliary disorders from organic gastrointestinal pathology was developed. Sphincter of Oddi dysfunction may be considered as a postcholecystectomy syndrome manifestation in 1.5-3% of cases. Apart from rational nutrition, conservative management of functional gastrointestinal diseases implies  pharmacological therapy. The efficacy of non-steroidal anti-inflammatory drugs, prokinetics, nitrates, antispasmodics, calcium channel antagonists, botulinum toxin, and hymecromone was demonstrated in previous studies. Papillosphincterotomy is not effective in relieving biliary pain in cases of the sphincter of Oddi dysfunction. The proposed algorithm for the management of patients with the postcholecystectomy syndrome was presented.Желчнокаменная болезнь выявляется у 10–20% населения и имеет четкую тенденцию к «омоложению». При наличии клинических симптомов основным методом лечения остается холецистэктомия, после которой у 10–15% пациентов клинические проявления сохраняются либо усиливаются (для обозначения таких ситуаций применяют термин «постхолецистэктомический  синдром»). Постхолецистэктомический синдром объединяет неоднородные расстройства, включая  нарушения функции печени, поджелудочной железы, двенадцатиперстной кишки, сфинктера Одди  пр., которые могут быть связаны с погрешностями или последствиями хирургических манипуляций. Зачастую причиной сохранения жалоб оказываются ранее нераспознанные хронические заболевания других органов. Арсенал эффективных средств медикаментозной и  немедикаментозной коррекции относительно невелик. С целью стандартизировать определения и  категории, касающиеся проблемы постхолецистэктомического синдрома, и разработать алгоритм обследования и лечения пациентов с постхолецистэктомической дисфункцией сфинктера  Одди 4 мая 2019 г. в городе Алматы (Казахстан) состоялся совет экспертов – представителей  междисциплинарной команды из гастроэнтерологов и хирургов. Целевая аудитория – врачи общей  практики, терапевты, гастроэнтерологи, хирурги. Согласно решению Экспертного совета, основным  клиническим проявлением органических и функциональных заболеваний желчных путей  является билиарная боль, подробные характеристики которой были выделены в материалах IV Римского консенсуса на основании статистического анализа большого объема клинических данных. Для более точной оценки состояния протоковой системы и исключения желчнокаменной болезни в план обследования включают ультразвуковое исследование органов брюшной полости,  эндоскопическое ультразвуковое исследование панкреато-билиарной зоны, магнитно-резонансную  холангиопанкреатографию. Функциональные билиарные расстройства необходимо дифференцировать с органическими заболеваниями органов пищеварения; с этой целью  рекомендован план обследования пациентов. Дисфункцию сфинктера Одди можно рассматривать как вариант постхолецистэктомического синдрома; на долю таких случаев приходится 1,5–3%. Консервативное ведение при функциональных заболеваниях органов пищеварения, помимо  рационального питания, подразумевает лекарственную терапию. Показана эффективность  нестероидных противовоспалительных препаратов, прокинетиков, нитратов, спазмолитиков, антагонистов кальциевых каналов, ботулотоксина и гимекромона. Папиллосфинктеротомия при  дисфункции сфинктера Одди не обладает должной эффективностью в купировании билиарной  боли. Разработан алгоритм ведения пациентов при появлении билиарной боли и другой  симптоматики после холецистэктомии

The Origins and Spread of Domestic Horses from the Western Eurasian Steppes

Domestication of horses fundamentally transformed long-range mobility and warfare1. However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of bridling, milking and corralling2–4 at Botai, Central Asia around 3500 bc3. Other longstanding candidate regions for horse domestication, such as Iberia5 and Anatolia6, have also recently been challenged. Thus, the genetic, geographic and temporal origins of modern domestic horses have remained unknown. Here we pinpoint the Western Eurasian steppes, especially the lower Volga-Don region, as the homeland of modern domestic horses. Furthermore, we map the population changes accompanying domestication from 273 ancient horse genomes. This reveals that modern domestic horses ultimately replaced almost all other local populations as they expanded rapidly across Eurasia from about 2000 bc, synchronously with equestrian material culture, including Sintashta spoke-wheeled chariots. We find that equestrianism involved strong selection for critical locomotor and behavioural adaptations at the GSDMC and ZFPM1 genes. Our results reject the commonly held association7 between horseback riding and the massive expansion of Yamnaya steppe pastoralists into Europe around 3000 bc8,9 driving the spread of Indo-European languages10. This contrasts with the scenario in Asia where Indo-Iranian languages, chariots and horses spread together, following the early second millennium bc Sintashta culture11,12. © 2021, The Author(s).We thank all members of the AGES group at CAGT.
