Topographic Analysis of the Periorbital Region Including Orbicularis Oculi Muscle Based on Ultrasonography Interpretation.
J Cosmet Dermatol
January 2025
Division in Anatomy and Developmental Biology, Department of Oral Biology, Human Identification Research Institute, BK21 FOUR Project, Yonsei University College of Dentistry, Seoul, South Korea.
Objective: Ultrasonographic examination is easy, fast, safe, and used in various fields; however, its application to the facial area has been limited. Complex anatomical structures are mixed within thin, soft tissues in the facial region; therefore, understanding their structural characteristics is crucial. This study aimed to use ultrasonography to obtain information on the layered structure and soft tissue thickness of the eye area around the orbicularis oculi muscle and provide guidance for clinical practice.

Department of Anatomy, School of Medicine, Faculty of Health Sciences, National and Kapodistrian University of Athens, Greece.
Purpose: To evaluate the impact of the temporal bone styloid process (SP) angulation on the carotid arteries (CA), both internal and external carotid arteries (ICA and ECA). The SP topographical variability and the clinical significance will be further discussed.
Materials: One hundred computed tomography angiographies (CTAs) (200 sides of 50 male and 50 female patients) were retrospectively studied.
Neuronal segmentation in cephalopod arms.
Nat Commun
January 2025
Committee on Development, Regeneration and Stem Cell Biology, The University of Chicago, Chicago, IL, USA.
Prehensile arms are among the most remarkable features of the octopus, but little is known about the neural circuitry controlling arm movements. Here, we report on the cellular and molecular organization of the arm nervous system, focusing on its massive axial nerve cords (ANCs). We found that the ANC is segmented.

Invest Ophthalmol Vis Sci
January 2025
State Key Laboratory of Ophthalmology, Optometry, and Visual Science, Eye Hospital, Wenzhou Medical University, Wenzhou, China.
Purpose: Changes associated with Alzheimer's disease (AD) may have measurable effects on the retina, which may facilitate early detection due to the eye's accessibility. Retinal pathology and the regulation of serine racemase (SR) were investigated in the retinas of APP(SW)/PS1(∆E9) mice.
Methods: SR in the retinas and the content of D-serine in the aqueous humor were analyzed.
The Topographic Map of the Midfoot: Implication for Improving Safety of Dorsal Approach of Midfoot Surgeries.
J Am Acad Orthop Surg Glob Res Rev
January 2025
From the Department of Anatomy, School of Medicine, Marmara University, Basibuyuk Yolu, Maltepe, Istanbul, Turkey (Dr. Ismailoglu, Dr. Sehirli, and Dr. Ayingen); the Department of Anatomy, School of Medicine, Acibadem Mehmet Ali Aydinlar University, Atasehir, Istanbul, Turkey (Dr. Bayramoglu and Dr. Savasan); and the Department of Orthopedic Surgery, Faculty of Medicine, Acibadem Mehmet Ali Aydinlar University, Atasehir, Istanbul, Turkey (Dr. Kocaoglu).
Purpose: The surgical approach for midfoot injuries classically requires dual dorsal incision and identification of the neurovascular structures that are susceptible to injury during the surgery. The aim of this study was to map the topographic anatomy of the dorsum of the foot along with tarsal joints for the dorsal approach of midfoot surgery that would facilitate the surgery and minimize the risk of neurovascular injuries for surgeons who specially focus on foot and ankle injuries.
Methods: The dorsum of the foot was evaluated in 12 feet injected with latex containing a red colorant to visualize the arterial vessels.
