Article Synopsis
- The lower urinary tract, consisting of the bladder and urethra, develops from the cloaca, with the bladder forming from the urogenital sinus and the urethra extending into the genital tubercle.
- Engineering a fully functional bladder lining is challenging, and the urethral epithelium's immune roles are under-researched, highlighting the need for a better understanding of the epithelial and mesenchymal interactions that drive development.
- This study identified specific genes involved in bladder and urethra development in mice, revealing differences in gene expression patterns related to sex and offering insights for future regenerative therapies.
Expanding Soil Invertebrate Knowledge in Panama: The Genus (Collembola, Entomobryidae) in the Parque Natural Metropolitano as a Study Case.
Insects
November 2024
Department of Evolutionary Biology, Ecology and Environmental Sciences, Universitat de Barcelona, 08028 Barcelona, Spain.
Panama, located in the heart of the Mesoamerican hotspot, harbors an extraordinary species diversity across the Tree of Life. The Collembola species of the genus play an important role in soil biological processes such as decomposition, being used to monitor soil health and functional parameters. However, the limitation of morphological characters and molecular resources hampers the evaluation of local soil diversity.

December 2024
Faculty of Medicine, Dokuz Eylul University, Izmir, Turkey.
Article Synopsis
- The study examines the superficial palmar branch of the radial artery (SUPBRA) to improve techniques for reconstructing palmar skin, focusing on its anatomy and harvesting methods.
- Researchers dissected 19 male hand specimens to gather detailed anatomical data, including dimensions and positions of key structures related to SUPBRA, analyzing how best to utilize this flap in reconstruction efforts.
- Results indicated that the SUPBRA has adequate dimensions for viability in surgical applications, with specific measurements and the identification of critical vascular contributions that ensure successful use in cases of hand injury.
Anatomical Insights: Two Case Reports on Protostylid Variants and Literature Synthesis.

Protostylids are an anatomical variant of the paramolar tubercle, which refers to the presence of an additional cusp in the buccal surfaces of maxillary and mandibular bicuspids and molars. This structure, first reported by Dahlberg in 1950, is found in low frequencies and plays a significant role in dental anthropology. This anatomical variant, if present poses a threat to dental caries and periodontal diseases and hence requires early diagnosis and preventive dental care.

The posterior cruciate ligament (PCL) is the strongest ligament of the knee and plays an important role in stabilizing the knee joint posteriorly. PCL tears are common injuries in sports injuries and traffic accidents; however, clinical outcomes after PCL reconstruction have not yet met clinicians' expectations, with a high postsurgery failure rate reported. Suture tape augmentation and supplementary fixation have shown ideal biomechanical properties in early studies.
