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

The territorial behavior of the red-whiskered bulbul, Pycnonotus jocosus, was studied in the semiwild habitat of a bird farm compound in the District of Chana, Songkhla Province, the south of Thailand. The male and female birds were bred and reared in the farm till they reached maturity following which they were released to the wild. A mating pair was later formed and their territory established in the farm area. A decoy was used to simulate a natural intruder to the defended area. Ten test stations were sited in the four cardinal points of the compass and with reference to the farmhouse. The

Introduction: Hypertrophic and keloid scars arise from abnormal healing processes in fibrous tissue where tissue repair and regeneration control mechanisms do not work well. The standard treatment is an intralesional steroid injection with triamcinolone acetonide (TA). This method is effective, but there are some side effects include hypopigmentation and tissue atrophy. The nanofat method has been applied to various skin conditions with fewer side effects. Therefore, the use of nanofat with its regenerative properties can be expected to yield better results.
