Predictive models for dysphagia in older adults
Introduction: Dysphagia is a common condition among older adults, closely linked to aging and neurodegenerative diseases. It can lead to malnutrition, frailty, and aspiration pneumonia, thereby impairing quality of life and clinical outcomes. Although various interventions may improve swallowing function, early identification of high-risk individuals remains challenging. Existing predictive models show inconsistent performance and lack systematic…

Neurocranial abnormalities in the Middle Pleistocene Homo erectus fossils from Hexian, China
The Middle Pleistocene Homo erectus cranium from Hexian (Hexian 1, PA 830), in central eastern China, has been studied fairly extensively with respect to its evolutionary position. However, analysis of a series of neurocranial abnormalities identified on the Hexian fossil has never been attempted. Here, we present the first study of these abnormalities identified on the Hexian cranium, including (1) multiple breakages (including cracking) that fr…

Understanding and assessing uncertainty of observational climate datasets for model evaluation using ensembles
In climate science, observational gridded climate datasets that are based on in situ measurements serve as evidence for scientific claims and they are used to both calibrate and evaluate models. However, datasets only represent selected aspects of the real world, so when they are used for a specific purpose they can be a source of uncertainty. Here, we present a framework for understanding this uncertainty of observational datasets which distingu…
Diachronic changes in craniofacial morphology among the middle–late Holocene populations from Hehuang region, Northwest China
OBJECTIVES: This study analyzes craniofacial shape variation in the Hehuang region of Northwest China within a population genetic framework, and takes a diachronic approach to explore the relationship betwee cultural discontinuity and biological continuity/discontinuity in the Hehuang region during the middle to late Holocene. MATERIALS AND METHODS: The sample comprises 76 adult skulls from five archaeological sites, ranging from 4,500 to 1,530 B…
Late Pleistocene archaic human crania from Xuchang, China
Morphological mosaics in early Asian humans Excavations in eastern Asia are yielding information on human evolution and migration. Li et al. analyzed two fossil human skulls from central China, dated to 100,000 to 130,000 years ago. The crania elucidate the pattern of human morphological evolution in eastern Eurasia. Some features are ancestral and similar to those of earlier eastern Eurasian humans, some are derived and shared with contemporaneo…
Early Pleistocene hominin deciduous teeth from the Homo antecessor Gran Dolina‐TD6 bearing level (Sierra de Atapuerca, Spain)
This study expands the list of plesiomorphic features of H. antecessor, and provides some information on the evolutionary status of this species. However, the identification of some advanced traits evinces a step towards the derived morphology of European Pleistocene teeth. The study of the deciduous dentition confirms the mosaic pattern of H. antecessor morphology revealed in previous studies of this hominin sample
A mandible from the Middle Pleistocene Hexian site and its significance in relation to the variability of Asian Homo erectus
Mandibular and dental features indicate that the Hexian mandible and teeth differ from northern Chinese H. erectus and European Middle Pleistocene hominins, but show some affinities with the Early Pleistocene specimens from Africa (Homo ergaster) and Java (H. erectus), as well as the Middle-Late Pleistocene mandible from Penghu, Taiwan. Compared to contemporaneous continental Asian hominin populations, the Hexian fossils may represent the surviva…
Dental Scratches and Handedness in East Asian Early Pleistocene Hominins
The current study aims to characterise dental scratches found on an East Asian hominin upper left central incisor (I1) and lower left lateral incisor (I2) from the Early Pleistocene (Meipu site, Yunxian County), and infer the preference for handedness of these two individuals by quantifying the orientation of dental scratches. The labial surfaces of these two teeth were observed and imaged using light microscopes and/or scanning electron microsco…
Micro-CT Imaging and Analysis of Enamel Defects on the Early Late Pleistocene Xujiayao Juvenile
Dental pathologies and enamel defects in East Asian hominins have rarely been reported. Here, we systematically document and describe a suite of enamel defects in the Xujiayao juvenile maxilla, an East Asian hominin from the early Late Pleistocene that may represent an unknown hominin lineage. In addition, we determine the chronology of growth disruptions represented by matched linear enamel hypoplasias, evaluate the long-held hypothesis that the…
The protective effects of cassava ( Manihot esculenta crantz ) leaf flavonoid extracts on liver damage of carbon tetrachloride injured mice

Craniofacial variation between southern and northern Neolithic and Modern Chinese
Previous studies propose that the Yangtze River is the geographic boundary separating northern and southern Chinese populations. In order to test this hypothesis, 19 Neolithic and 15 Modern human cranial samples from north of the Qinling Mountain Range, south of the Yangtze River and in between were chosen for morphometric analysis. Our results indicate that cranial variation exists in Holocene Neolithic and Modern northern and southern Chinese. …

HIV prevention for injection drug users in China and Vietnam
A pattern of serious injection drug user (IDU) driven HIV epidemics in Asia, with emerging evidence of generalization through heterosexual transmission, indicates the need for interventions focusing on both drug- and sex-related risk reduction. In a cross-border HIV prevention project for IDUs in northern Vietnam and southern China, peer educators disseminated risk reduction information to IDUs in the community and provided 20,000-25,000 sterile …
Endocranial cast of HexianHomo erectus from South China
In this paper, we present data on the morphological features and linear measurements for the Hexian Homo erectus and other comparative endocasts, in order to highlight variation during human brain evolution. The endocast of Hexian was reconstructed in 1982, and an endocranial volume of 1,025 ml was estimated. The geological age is about 412 ka, or roughly contemporaneous with the Zhoukoudian (ZKD) specimens. There are some differences between Hex…
New Tooth of Peking Man Recognized in Laboratory at Uppsala University
Peking Man, originally named Sinanthropus pekinensis and now known as Homoerectus pekinensis, was among the best documented extinct hominids before the catastrophic lossof almost all the material in 1941. The only diagnostic specimens to survive from the originalexcavations are some teeth in the paleontological collections of Uppsala University, Sweden(PMU). Here we report on the discovery of a new tooth in the PMU collection with notes on thehis…

Brief communication
The frequency and form of the middle trigonid crest (MTC) in lower permanent molars is reported for 1,131 dental casts of Bushman (San), Bantu, Solomons, Hawaiians, Pima, Eskimo, Navajo, Chinese, and American whites. The MTC occurs most often on the first molar. We found very little intra‐trait variation, so observations were scored on a present‐absent basis. The MTC is most frequent in the African samples and rare in those of the other populatio…
