Isolation of the left common carotid or left innominate artery from the aortic arch is rare. A six week malformed infant with a right aortic arch had isolation of a left innominate artery and connection to the pulmonary artery by a left ductus arteriosus. A right ductus arteriosus had been ligated. Another infant with a right aortic arch and ostium primum atrial septal defect was shown to have an aberrant left subclavian artery arising from the lower descending aorta. The left common carotid artery filled retrogradely and drained into the pulmonary artery by a left ductus arteriosus. This abnormality has not been reported before.

Therapeutic Dilemma of a Juxtapapillary Retinal Capillary Hemangioma.
Cureus
December 2024
Department of Ophthalmology and Visual Science, Ophthalmology Clinic, Hospital Universiti Sains Malaysia, Universiti Sains Malaysia, Kubang Kerian, MYS.
A juxtapapillary retinal capillary hemangioma (JRCH) is a rare vascular hamartoma located on the optic nerve head or adjacent region. While often associated with von Hippel-Lindau (VHL) disease, JRCHs can also occur as an isolated condition, presenting unique therapeutic challenges and risks of visual impairment. We report a case of a 50-year-old Malay gentleman with diabetes mellitus who presented with a non-progressive superior visual field defect in his left eye for three months.

Department of Cardiovascular Surgery, Kobe University, Kobe, Hyogo, Japan.
Purpose: In totally endoscopic off-pump left atrial appendage (LAA) closure and surgical ablation, securing the operative field is sometimes difficult in some patients because of a narrow working space caused by an elevated diaphragm or ventricles. In this study, we aimed to investigate the effectiveness of a method that facilitates securing the operative field using an artificial pneumothorax.
Methods: We analyzed 71 consecutive patients who underwent totally endoscopic off-pump LAA closure and bilateral pulmonary vein isolation.

State Key Laboratory of Developmental Biology of Freshwater Fish, Engineering Research Center of Polyploid Fish Reproduction and Breeding of the State Education Ministry, College of Life Sciences, Hunan Normal University, Changsha 410081, China.
Background: Genomic data have unveiled a fascinating aspect of the evolutionary past, showing that the mingling of different species through hybridization has left its mark on the histories of numerous life forms. However, the relationship between hybridization events and the origins of cyprinid fishes remains unclear.
Results: In this study, we generated de novo assembled genomes of 8 cyprinid fishes and conducted phylogenetic analyses on 24 species.
Robot-assisted Endodontic Retreatment: A Case Report with Clinical Considerations.

Electronic address:
Introduction: Fiber posts present significant challenges for nonsurgical endodontic retreatment, as improper removal may result in iatrogenic root perforation or even root fracture. Recently, robotic technology has attracted considerable attention in dentistry and active dental robotic (ADR) systems can perform procedures based on preset instructions, minimizing reliance on the dentist's experience. This case report describes the application of an ADR system for fiber post removal through an existing zirconia crown.

Illicit drugs are often made in less-than-sterile environments and can be stored in ways which can be detrimental to any DNA present, such as whether they are exposed to UV radiation. Previously, analysis of how exposure to UV impacted DNA for forensic applications has been in controlled laboratory conditions isolating a single component of UV radiation and often on DNA-rich samples such as bloodstains or saliva. To evaluate DNA persistence in more realistic conditions, capsules, such as those used to distribute controlled substances, were manually made and then packed into ziplock bags.
