Arthroscopic Posterior Cruciate Ligament Reconstruction Using a Pedicled Semitendinosus Autograft Through a Trans-Septal Approach: A Technical Note. [PDF]

Arthrosc Tech
Abstract Isolated posterior cruciate ligament (PCL) ruptures are relatively uncommon among knee ligament injuries. Operative management is recommended for patients with grade III posterior knee joint laxity. The complex anatomy of the PCL, particularly its course and insertion on the femur and the tibia, makes its reconstruction technically challenging.

Transillumination Instrument Facilitates Faster and More Accurate Dissection of Right Colon Segment for Oesophageal Reconstruction

Asian Journal of Surgery, 2010
Venous insufficiency of a right colon interposition in oesophageal reconstruction can be a fatal complication. The right colon segment could allow restoration of swallowing and speech in reconstruction of the entire oesophagus. The right colon segment is

Complex Refractive Index Determination Via Microspectroscopy Through Magnifying Optics: Challenges and Opportunities

Small Methods, EarlyView.
Microspectroscopy combines a standard optical microscope with a spectrometer to measure reflectance and transmittance of samples down to the microscale. A numerical formalism that explicitly accounts for the high numerical aperture of magnifying optics retrieves complex refractive indices.

Husbandry factors are associated with skin, gastrointestinal and ophthalmic disorders in leopard geckos (Eublepharis macularius)

Veterinary Record, EarlyView.
Abstract Background Research into disorders in captive reptiles is notably sparse in the UK, despite the popularity of various species as pets. This study aimed to survey and investigate risk factors for disorders of leopard geckos in the UK. Methods Medical records for leopard geckos presenting at three veterinary practices between 2019 and 2023 were ...
