This case report presents an atypical transverse cervical artery with its detailed anatomy, morphogenesis, and association with the high arch-shaped subclavian artery. The atypical arteries, related arteries, and adjacent cervical and brachial plexuses were macroscopically examined in a 98-year-old Japanese female cadaver donated to The Nippon Dental University for medical education and research. The atypical deep branch of the transverse cervical artery originated from the internal thoracic artery and passed through between the C5 and C6 roots, in close contact with the C5 and C6 junction, to reach the dorsal side of the brachial plexus.

Forensic gemstone analysis faces many challenges. One of the most critical aspects of gemological research is the classification of a gemstone. It is necessary to understand the mineral species, purity, origin, and identification of treatments to identify and classify a gem correctly, as well as assign a monetary value to it.

Background: Congenital coronary artery anomalies (CAAs) are a significant cause of sudden cardiac death and a key factor in determining athletes' eligibility for competitive sports. Their prevalence varies with diagnostic modalities and may present as asymptomatic or with life-threatening ischemic or arrhythmic events. This case series highlights the diverse manifestations of CAAs and the clinical approaches used to determine sports eligibility.

Purpose: An anomalous aortic origin of the coronary artery (AAOCA) is a rare congenital heart disease. Some high-risk anatomical structures are at risk of inducing cardiogenic shock or even sudden death. This article summarizes our surgical experience with AAOCA in paediatric patients.

So far, the striking sign reversal in the near-ambient slope of the gap temperature dependence of colloidal CsPbCl perovskite nanocrystals (NCs) compared to its Br counterpart remains unresolved. Pure bromide NCs exhibit a linear gap increase with increasing temperature, to which thermal expansion and electron-phonon interaction equally contribute. In contrast, the temperature slope for the chlorine compound gap is clearly negative.
