in wistar rats, reproductive behavior is controlled in a neural circuit of ventral forebrain including the medial amygdala (me), bed nucleus of the stria terminalis (bnst) and medial preoptic area (mpoa) via perception of social odors. diabetes mellitus (dm) is a widespread metabolic disease that affects many organs in a variety of levels. dm can cause central neuropathies such as neuronal apop...

OBJECTIVE To devise a reliable, sensitive method to measure joint space in vivo during dynamic loading. Additionally, to determine if dynamic joint space changes were related to the severity of long-term cartilage damage. DESIGN Subjects were 23 adult foxhounds (18 experimental, 5 control). Experimental subjects had surgically transected cranial cruciate ligaments (CCL). Dynamic joint space w...

OBJECTIVE To determine the comparative prevalence, associations with selected patient characteristics, and clinical outcomes of medial and lateral compartment patellofemoral (PF) joint osteoarthritis (OA). METHODS Information was collected by questionnaires, clinical assessment, and radiographs from 745 eligible community-dwelling symptomatic adults age ≥50 years. PF joint space narrowing (JS...

This paper addresses the problem of obtaining a concise description of a physical environment for robotic exploration. We aim to determine the number of robots required to clear an environment using non-recontaminating exploration. We introduce the medial axis as a configuration space and derive a mathematical representation of a continuous environment that captures its underlying topology and ...

OBJECTIVE To evaluate foot and ankle function in a series of patients undergoing fibula microvascular free tissue transfer. STUDY DESIGN A nonrandomized, nonblinded analysis was performed using the ankle-hindfoot scale as well as radiographic analysis to determine donor site morbidity. RESULTS Overall, foot ankle function was deemed to be good in this series of patients. Average ankle-hindf...

Post-traumatic premature closure of the distal fibular growth plate is a rare entity leading to shortening of the lateral malleolus. We report on a 14-year old boy who presented with a 4-year history of worsening, diffuse discomfort and swelling of his left ankle, as well as fibular shortening and talar malreduction. He had sustained a distal tibial fracture 4 years earlier and had been treated...

We present a technique for organizing data in spatial databases with non-convex domains based on an automatic characterization using the medial-axis transform (MAT). We define a tree based on the MAT and enumerate its branches to partition space and define a linear order on the partitions. This ordering clusters data in a manner that respects the complex shape of the domain. The ordering has th...
