Direct recordings were made of electrical signals emanating from the muscles in a rabbit's residuum. The signals were transmitted via wires attached on one end to the muscles, and on the other to an external recording system. The cable was held in a titanium tube inside a pylon that had been transcutaneously implanted into the residuum's bone. The tube was surrounded by porous titanium cladding to enhance its bond with the bone and with the skin of the residuum. This study was the first known attempt to merge the technology of direct skeletal attachment of limb prostheses with the technology of neuromuscular control of prostheses, providing a safe and reliable passage of the electrical signal from the muscles inside the residuum to the outside recording system.

Dinosaur locomotor biomechanics are of major interest. Locomotion of an animal affects many, if not most, aspects of life reconstruction, including behaviour, performance, ecology and appearance. Yet locomotion is one aspect of non-avian dinosaurs that we cannot directly observe.

Climate change is imposing multiple stressors on marine life, leading to a restructuring of ecological communities as species exhibit differential sensitivities to these stressors. With the ocean warming and wind patterns shifting, processes that drive thermal variations in coastal regions, such as marine heatwaves and upwelling events, can change in frequency, timing, duration, and severity. These changes in environmental parameters can physiologically impact organisms residing in these habitats.

Background: Advances in technology and affordability of ultrasound (US) have expanded its use in the evaluation of musculoskeletal injuries. However, US accuracy for diagnosing anterior cruciate ligament (ACL) injuries remains inconsistently reported in the literature.
Hypothesis/purpose: Systematically review the literature and perform a meta-analysis to statistically evaluate the accuracy of US in diagnosing ACL tears.

Objectives: This study aims to assess the alterations in condylar positioning in adult skeletal Class I patients with unilateral posterior crossbite after microimplant-assisted rapid palatal expansion (MARPE) treatment.
Methods: This retrospective study involving 30 participants (10 males, 20 females) average age 22.9 ± 4.
Objectives: To examine tooth root length and root volume in cone beam computed tomography (CBCT) images in patients with skeletal Class II and III anomalies who have undergone single-jaw (SJ) and double-jaw (DJ) orthognathic surgery, and to compare the changes between jaws with and without osteotomy.
Materials And Methods: This study was conducted on the archive records of a total of 60 adults: 36 women and 24 men with an average age of 21.1 ± 3.
