Human burials indicate climate-mediated shifts in South African agriculturalist demography after 2000 years ago

Scientific Reports
South Africa’s Iron Age (c. 250 CE – 1850 CE) was a period of socio-economic transitions. With the spread of Bantu-speaking peoples from western Africa, the region saw the development of settled agriculturalist societies, the rise of complex chiefdoms ...

Anatomical variations during mastoidectomy

Kafkas Journal of Medical Sciences, 2011
RESULTS: In 8 (2.6%) patients, the entrance to mastoid antrum was troublesome due to Korner septum. In three patients a dehiscence in the bony canal were noted which proned these patients to possible facial nerve injury. In 4 (1.3%) patients, dura was open to surgical cavity due to dehiscence of the tegmen timpany and in 3 (1%) patients, dura was as ...

Primate modularity and evolution: first anatomical network analysis of primate head and neck musculoskeletal system [PDF]

, 2018
Network theory is increasingly being used to study morphological modularity and integration. Anatomical network analysis (AnNA) is a framework for quantitatively characterizing the topological organization of anatomical structures and providing an ...

Fracture Resistance of Zirconia Oral Implants In Vitro: A Systematic Review and Meta-Analysis [PDF]

, 2020
Various protocols are available to preclinically assess the fracture resistance of zirconia oral implants. The objective of the present review was to determine the impact of different treatments (dynamic loading, hydrothermal aging) and implant features (

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Was human evolution driven by Pleistocene climate change? [PDF]

, 2014
Modern humans are probably a product of social and anatomical preadaptations on the part of our Miocene australopithecine ancestors combined with the increasingly high amplitude, high frequency climate variation of the Pleistocene.

Tumor mutational burden as a determinant of metastatic dissemination patterns

Molecular Oncology, EarlyView.
This study performed a comprehensive analysis of genomic data to elucidate whether metastasis in certain organs share genetic characteristics regardless of cancer type. No robust mutational patterns were identified across different metastatic locations and cancer types.

RaMBat: Accurate identification of medulloblastoma subtypes from diverse data sources with severe batch effects

Molecular Oncology, EarlyView.
To integrate multiple transcriptomics data with severe batch effects for identifying MB subtypes, we developed a novel and accurate computational method named RaMBat, which leveraged subtype‐specific gene expression ranking information instead of absolute gene expression levels to address batch effects of diverse data sources.
