Background: Identifying individuals based on their height is of great importance, especially in cases such as accidents or burns where identifying individuals is challenging. Therefore, the aim of this study was to investigate upper extremity parameters in a population of Bushehr in a relative formulation to predict their stature using anatomical indices. Materials and Methods: The project involved men and women aged 18 to 50 who were themselves born and both they and two generations before them also lived there. The indices of arm, forearm, hand, upper extremity, and stature were measured in

Mouse digit amputation provides a useful model of bone growth after injury, in that the injury promotes intramembranous bone formation in an adult animal. The digit tip is composed of skin, nerves, blood vessels, bones, and tendons, all of which regenerate after digit tip amputation, making it a powerful model for multi-tissue regeneration. Bone integrity relies upon a balanced remodeling between bone resorption and formation, which, when disrupted, results in changes to bone architecture and biomechanics, particularly during aging. In this study, we used recently developed techniques to evalu

Background: Reconstruction of the medial collateral ligament (MCL) and posterior oblique ligament (POL) is necessary to restore stability in chronic lesions on the medial side of the knee. The Lind technique uses a single-strand, pedicled semitendinosus tendon autograft to perform continuous reconstruction of the MCL and POL. The LaPrade technique uses 2 free grafts: 1 graft for the MCL (double-strand semitendinosus tendon graft) and 1 graft for the POL (double-strand gracilis tendon graft). Purpose: To investigate the LaPrade and Lind techniques in restraining tibial translation and rotation

A total of 13 healthy older (ages 56–74) individuals were studied on two successive evenings. Prior to the first evening, the participants were in self-selected lighting conditions for the first 4–6 h of the day and then were in dim light (3 lux) until their scheduled bedtime. On the second day, individuals from Project A remained in the dim lighting conditions throughout the entire day but those in Project B were in more typical indoor l
