OBJECTIVE High-mobility group box-1 (HMGB1) protein is a nuclear DNA-binding protein released from necrotic cells, inducing inflammatory responses and promoting tissue repair and angiogenesis. Diabetic human and mouse tissues contain lower levels of HMGB1 than their normoglycemic counterparts. Deficient angiogenesis after ischemia contributes to worse outcomes of peripheral arterial disease in ...

DWYER, C. M., and HANKEN, J . 1990. Limb skeletal variation in the Jemez Mountains salamander, Plethodon neomexicanus. Can. J. Zool. 68: 1281-1287. We examine limb skeletal variability in Plethodon neomexicanus, a geographically isolated species of plethodontid salamander endemic to the Jemez Mountains of New Mexico, U . S . A. Data are derived from a series of 25 specimens prepared as whole mo...

The hip region is examined to determine what aspects of musculoskeletal anatomy are precociously developed in primate species with highly specialized modes of locomotion. Muscles of the hind limb were removed and weighed in each specimen, and the hip joint of selected specimens was studied in stained serial sections. No perinatal differences among species are evident, but in adults, the hip joi...

Objective: The aim of this work was to explore the therapeutic effect of bone marrow-derived mesenchymal stem cells transplantation in SD rats’ ischemic hind limb. Methods: Ligation of the abdominal aorta beneath the renal artery, the lumbar artery and the iliolumbar artery, was performed to obtain the hindlimb ischemia model in female SD rats. Amplified and purified bone marrow-derived mesench...

The role of sensory feedback in the early ontogeny of motor coordination remains a topic of speculation and debate. On E20 of gestation (the 20th day after conception, 2 days before birth), rat fetuses can alter interlimb coordination after a period of training with an interlimb yoke, which constrains limb movement and promotes synchronized, conjugate movement of the yoked limbs. The aim of thi...

Safflower yellow (SY) is the safflower extract and is the one of traditional Chinese medicine. The aim of the present work was to investigate the effect of SY on spinal cord ischemia reperfusion injury (SCIRI) in rabbits. The models of spinal cord ischemia reperfusion (SI/R) were constructed, and the degree of the post-ischemic injury was assessed by means of the neurological deficit scores and...

Measurements of laser-stimulated action potentials in the sciatic nerve of leopard frogs (Rana pipiens) are made using two infrared lasers. The dorsal sides of the frog's hind limbs are exposed to short-pulsed 1540- and 1064-nm wavelengths at three separate spot sizes: 2, 3, and 4 mm. Energy density thresholds are determined for eliciting an action potential at each experimental condition. Resu...

This report presents the use of feed forward ANNs with accelerated Back propagation and Support Vector Regression to predict the joint angles of walking cats using the EMG signals obtained from several muscles of the cat hind and fore limbs. The MATLAB software was used with NN and SVM tools. The results have demonstrated that, both methods can be effectively used to predict the joint angles, i...

A comparative histologic survey was conducted on the dorsal root, sciatic, tibial and medial plantar nerves of 90- and 110-week-old B6C3F1 female mice reared in either solid-floor cages covered in sawdust or wire-mesh-floor cages. Age-related peripheral nerve lesions, characterized by axonal degeneration and remyelination, were present in all nerves surveyed, and were especially prominent in th...
