Saleem, S. N., and Z. Hawass, "Computed Tomography Study of the Mummy of King Seqenenre Taa II: New Insights Into His Violent Death.", Frontiers in medicine, vol. 8, pp. 637527, 2021. Abstractseqenenre_frontiers_2021.pdf

Seqenenre-Taa-II, The Brave, (c.1558-1553 BC) ruled Southern Egypt during the occupation of Egypt by the Hyksos. The mummy was physically examined and X-rayed in the 1960s, which showed severe head wounds that have prompted various theories about the circumstances of his death. We postulated that Computed Tomography (CT) study of Seqenenre-Taa-II's mummy would give insights into the circumstances of his death. We examined Seqenenre's mummy using CT and compared the findings with the archaeological literature as well as with five Asian weapons found in Tell-el-Dabaa. CT findings indicate that Seqenenre died in his forties. The mummies deformed hands suggest that the King was likely imprisoned with his hands tied. CT images provided detailed analysis of Seqenenre's previously reported injuries to the forehead, right supra-orbital, nose-right orbit, left chick, and skull base. This study revealed additional craniofacial fractures in the right lateral side of the skull that had been concealed by the embalmers beneath layers of material. Analysis of the morphology of the injuries enabled a better understanding of the mechanism of trauma, possible number of the attackers, and their relative position to the King. The size and shape of the fractures correlated well with the studied Hyksos weapons. The lethal attack was aimed at the King's face, likely in an attempt to disgrace him. Mummification of Seqenenre's body was limited to evisceration without brain removal. The desiccated brain is shifted to the left side of the skull. This may indicate that the King's dead body stayed on its left side for some time-long enough for decomposition start before the mummification began. This suggests that the King likely died at a location distant from the funeral place, possibly on a battlefield. The embalmers attempted to conceal the King's injuries; the methods used suggest that the mummification took place in a royal mummification workshop rather than in a poorly equipped location. CT findings of Seqenenre's mummy helped us to better understand the circumstances of his violent death. His death motivated his successors to continue the fight to unify Egypt and start The New Kingdom.

Patients lacking PYCR2, a mitochondrial enzyme that synthesizes proline, display postnatal degenerative microcephaly with hypomyelination. Here we report the crystal structure of the PYCR2 apo-enzyme and show that a novel germline p.Gly249Val mutation lies at the dimer interface and lowers its enzymatic activity. We find that knocking out Pycr2 in mice phenocopies the human disorder and depletes PYCR1 levels in neural lineages. In situ quantification of neurotransmitters in the brains of PYCR2 mutant mice and patients revealed a signature of encephalopathy driven by excessive cerebral glycine. Mechanistically, we demonstrate that loss of PYCR2 upregulates SHMT2, which is responsible for glycine synthesis. This hyperglycemia could be partially reversed by SHMT2 knockdown, which rescued the axonal beading and neurite lengths of cultured Pycr2 knockout neurons. Our findings identify the glycine metabolic pathway as a possible intervention point to alleviate the neurological symptoms of PYCR2-mutant patients.

Abstract

OBJECTIVE: The goal of this study is to demonstrate the need for interdisciplinary consensus and inclusion of mummy radiology specialists in analyses of mummified remains.

MATERIALS: This study uses paleoimaging data for an ancient Egyptian mummy at the Museum of Human Anatomy "Filippo Civinini".

METHODS: This study demonstrates the benefit of evaluation of mummified remains in a multi-disciplinary interpretive team.

RESULTS: The authors propose a diagnosis of DISH, additional signs of undifferentiated spondyloarthropathy, and lumbarisation of S1.

CONCLUSIONS: The process of diagnosis by consensus is essential to the analysis of mummified remains, which are complexly altered through natural and anthropogenic processes in the millennia subsequent to the individual's death.

SIGNIFICANCE: Mummy paleoimaging and paleopathology lacks a unifying set of standards. We present an example of the value to be found in the multi-disciplinary diagnosis by consensus approach.

LIMITATIONS: We discuss numerous challenges to accurate and meaningful interpretation that radiography of mummified remains pose.

SUGGESTIONS FOR FURTHER RESEARCH: While the authors do not seek to impose any single set of standards, we do recommend a larger discussion on the topic of (culture-specific) standardisation in mummy paleoimaging and paleopathology. We further recommend the development of an international, multi-disciplinary panel of paleoimaging interpreters.

Akizu, et al., "Loss of Protocadherin-12 Leads to Diencephalic-Mesencephalic Junction Dysplasia Syndrome.", Annals of neurology, vol. 84, issue 5, pp. 638-647, 2018 Nov. Abstract

OBJECTIVE: To identify causes of the autosomal-recessive malformation, diencephalic-mesencephalic junction dysplasia (DMJD) syndrome.

METHODS: Eight families with DMJD were studied by whole-exome or targeted sequencing, with detailed clinical and radiological characterization. Patient-derived induced pluripotent stem cells were derived into neural precursor and endothelial cells to study gene expression.

RESULTS: All patients showed biallelic mutations in the nonclustered protocadherin-12 (PCDH12) gene. The characteristic clinical presentation included progressive microcephaly, craniofacial dysmorphism, psychomotor disability, epilepsy, and axial hypotonia with variable appendicular spasticity. Brain imaging showed brainstem malformations and with frequent thinned corpus callosum with punctate brain calcifications, reflecting expression of PCDH12 in neural and endothelial cells. These cells showed lack of PCDH12 expression and impaired neurite outgrowth.

INTERPRETATION: DMJD patients have biallelic mutations in PCDH12 and lack of protein expression. These patients present with characteristic microcephaly and abnormalities of white matter tracts. Such pathogenic variants predict a poor outcome as a result of brainstem malformation and evidence of white matter tract defects, and should be added to the phenotypic spectrum associated with PCDH12-related conditions.

MRI has been increasingly used for detailed visualization of the fetus in utero as well as pregnancy structures. Yet, the familiarity of radiologists and clinicians with fetal MRI is still limited. This article provides a practical approach to fetal MR imaging. Fetal MRI is an interactive scanning of the moving fetus owed to the use of fast sequences. Single-shot fast spin-echo (SSFSE) T2-weighted imaging is a standard sequence. T1-weighted sequences are primarily used to demonstrate fat, calcification and hemorrhage. Balanced steady-state freeprecession (SSFP), are beneficial in demonstrating fetal structures as the heart and vessels. Diffusion weighted imaging (DWI), MR spectroscopy (MRS), and diffusion tensor imaging (DTI) have potential applications in fetal imaging. Knowing the developing fetal MR anatomy is essential to detect abnormalities. MR evaluation of the developing fetal brain should include recognition of the multilayered-appearance of the cerebral parenchyma, knowledge of the timing of sulci appearance, myelination and changes in ventricular size. With advanced gestation, fetal organs as lungs and kidneys show significant changes in volume and T2-signal. Through a systematic approach, the normal anatomy of the developing fetus is shown to contrast with a wide spectrum of fetal disorders. The abnormalities displayed are graded in severity from simple common lesions to more complex rare cases. Complete fetal MRI is fulfilled by careful evaluation of the placenta, umbilical cord and amniotic cavity. Accurate interpretation of fetal MRI can provide valuable information that helps prenatal counseling, facilitate management decisions, guide therapy, and support research studies.

Knowledge of the anatomy of the developing fetal brain is essential to detect abnormalities and understand their pathogenesis. Capability of magnetic resonance imaging (MRI) to visualize the brain in utero and to differentiate between its various tissues makes fetal MRI a potential diagnostic and research tool for the developing brain. This article provides an approach to understand the normal and abnormal brain development through schematic interpretation of fetal brain MR images. MRI is a potential screening tool in the second trimester of pregnancies in fetuses at risk for brain anomalies and helps in describing new brain syndromes with in utero presentation. Accurate interpretation of fetal MRI can provide valuable information that helps genetic counseling, facilitates management decisions, and guides therapy. Fetal MRI can help in better understanding the pathogenesis of fetal brain malformations and can support research that could lead to disease-specific interventions.

Saleem, S. N., and Z. Hawass, "Variability in Brain Treatment During Mummification of Royal Egyptians Dated to the 18th–20th Dynasties: MDCT Findings Correlated With the Archaeologic Literature", American Journal of Roentgenology, vol. 200, issue 4, pp. W336-W344, 2013. Abstract

OBJECTIVE. The objective of our study was to use MDCT to study brain treatment and removal (excerebration) as part of mummification of royal Egyptian mummies dated to the 18th to early 20th Dynasties and to correlate the imaging findings with the archaeologic literature.

MATERIALS AND METHODS. As part of an MDCT study of the Royal Ancient Egyptian Mummies Project, we analyzed CT images of the heads of 12 mummies dated to circa 1493–1156 BC (18th to early 20th Dynasties). We reconstructed and analyzed CT images for the presence of cranial defects, brain remnants, intracranial embalming materials, and nasal packs. We compared the CT findings of mummies dated to the 18th Dynasty with those dated to the 19th to early 20th Dynasties.

RESULTS. The Akhenaten mummy was excluded because of extensive postmortem skull fractures. CT showed that no brain treatment was offered to three mummies (Thutmose I, II, and III) who dated to the early 18th Dynasty and was offered to the eight mummies who dated later. The route of excerebration was transnasal in eight mummies; an additional suspected route was via a parietal defect. CT showed variable appearances of the intracranial contents. There were larger volumes of cranial packs and more variability in the appearances of the cranial packs in the royal mummies dated to the 19th to 20th Dynasties than in those dated to the 18th Dynasty.

CONCLUSION. MDCT shows variations in brain treatment during mummification of royal Egyptian mummies (18th–20th Dynasties). This study sets a template for future CT studies of the heads of ancient Egyptian mummies and focuses on the key elements of cranial mummification in this ancient era.
