plays an essential role in pharyngeal cartilage development.

Neural crest cells constitute a distinct set of multipotent cells that undergo migration along predefined pathways, culmination in the differentiation into a plethora of cell types, including components of the pharyngeal cartilage. The neurocranium is composite structure derived from both cranial neural crest and mesoderm cells, whereas the pharyngeal skeletal elements-including the mandibular and branchial arches-are exclusively formed by craniofacial neural crest cells. Previous studies have elucidated the critical involvement of the chemokine signaling axis Cxcl12b/Cxcr4a in craniofacial development in zebrafish ().

The cardiovascular toxicity of clozapine in embryonic zebrafish and RNA sequencing-based transcriptome analysis.

Clozapine (CLZ) is the most prescribed medication for treating refractory schizophrenia but is associated with significant cardiovascular toxicity. This study aimed to investigate the cardiovascular toxicity induced by CLZ using zebrafish as a model animal. For this purpose, zebrafish developed to 80-h post-fertilization were exposed to different CLZ concentration solutions for 24 h followed by cardiac morphological observations in yolk sac edema, pericardial edema, and blood coagulation, in addition to increased SV-BA distance, functionally manifested as bradycardia, and decreased cardiac ejection fraction using the untreated embryos as control.

An Autopsy Analysis of a Patient With Long-Chain 3-Hydroxyacyl-CoA Dehydrogenase Deficiency Caused by Compound Heterozygous HADHA Gene Mutations.

Long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency is a rare mitochondrial disease characterized by lipid oxidation disorder. It is an autosomal recessive disease induced by a mutation in the HADHA gene, which encodes the LCHAD deficiency. The clinical manifestations of this disease are diverse, primarily affecting the heart, liver, and skeletal muscles.

Genetic Ablation of GIGYF1, Associated With Autism, Causes Behavioral and Neurodevelopmental Defects in Zebrafish and Mice.

Background: Autism spectrum disorder is characterized by deficits in social communication and restricted or repetitive behaviors. Due to the extremely high genetic and phenotypic heterogeneity, it is critical to pinpoint the genetic factors for understanding the pathology of these disorders.

Methods: We analyzed the exomes generated by the SPARK (Simons Powering Autism Research) project and performed a meta-analysis with previous data.

Exploring the genetic pathogenicity of aortic dissection from 72 Han Chinese individuals using next-generation sequencing.

Aortic dissection (AD) is a heterogeneous genetic disease with high morbidity and mortality. Although many genes predispose patients to AD, the pathogenic spectrum remains incomplete. This study aims to (a) investigate whether genotype differences exist between Stanford A and B AD individuals, and (b) broaden the pathogenic genetic spectrum of AD and reported novel variants of AD-associated genes.

Retrospective analysis of 172 cases of custodial deaths in China between 1999 and 2016: forensic experience in China.

Custodial deaths refer to the death of an individual who is in prison, a detention center, or a police station. The present study aims to retrospectively analyze cases of custodial deaths examined at Tongji Medico Legal Expertise Center in Hubei (TMECH). A total of 172 out of 5853 cases were screened at TMECH from January 1999 to December 2016.

Unexpected custodial death due to acute epiglottitis: A rare autopsy case report.

Rationale: Acute epiglottitis is a potentially life-threaten disease, which makes it more challenging to save the life for doctors. Unexpected deaths in custody are a primary cause of concern for the forensic community and doctor worldwide.

Patient Concerns: We present a case of a 44-year-old male detainee who was clinically suspected of dying of acute epiglottitis.

A Study on the Estimation of Postmortem Interval Based on Environmental Temperature and Concentrations of Substance in Vitreous Humor.

A method to determine postmortem interval (PMI) based on environmental temperature and the concentrations of vitreous humor (VH) molecules were explored. Rabbit carcasses were placed in a chamber at 5, 15, 25, or 35°C, and 80-100 μL of VH was collected with the double-eye alternating micro-sampling method every 12 h. A Roche DPPI biochemical analyzer was used to measure the concentrations of six substances in VH samples.

Retrospective analysis of 769 cases of sudden cardiac death from 2006 to 2015: a forensic experience in China.

Sudden cardiac death (SCD) is a major health challenge. The records of 769 autopsy cases of SCD examined at Tongji Medicolegal Expertise Center from January 2006 to December 2015 were retrospectively reviewed. The mean age of the cases was 46 years, excluding 27 victims in whom the exact age could not be confirmed.
