Descending projections from the dysgranular zone of rat primary somatosensory cortex processing deep somatic input.
We examined this issue by using the rodent somatic system as a model. In rat SI, deep somatic input is processed mainly in the dysgranular zone (DSZ) enclosed by the cutaneous barrel subfields. By using biotinylated dextran amine (BDA) as anterograde tracer, we characterized the topography of cortic...
Recruitment of progenitor cells by an extracellular matrix cryptic peptide in a mouse model of digit amputation.
Biologic scaffolds composed of extracellular matrix (ECM) have been used successfully in preclinical models and humans for constructive remodeling of functional, site-appropriate tissue after injury. The mechanisms underlying ECM-mediated constructive remodeling are not completely un...
Functional micro-ultrasound imaging of rodent cerebral hemodynamics.
We present a new method to investigate microvascular hemodynamics in living rodent brain through a focal cranial window based on high-frequency ultrasound imaging. The method has a temporal resolution of 40ms, and a 100μm in-plane and 600μm through-plane spatial resolution. We use a commercially a...
Targeted mini-strokes produce changes in interhemispheric sensory signal processing that are indicative of disinhibition within minutes.
We evaluated the effect of mini-strokes over short timescales (<2 h) where cortical rewiring is unlikely by monitoring sensory-evoked activity throughout much of both cortical hemispheres using voltage-sensitive dye imaging. Blockade of a single pial arteriole within the C57BL6J mouse forelimb somat...
Comparison of conventional and alternative arthroscopic approaches to the palmar/plantar pouch of the equine distal interphalangeal joint.
The novel lateral/medial approach to the DIPJ significantly decreases the risk of inadvertent penetration of the DFTS and NB. Potential relevance: The novel lateral/medial approach to the DIPJ is an effective technique to gain access to the palmar/plantar pouches, and is particularly advantageous fo...
High-field magnetic resonance imaging investigation of distal border fragments of the navicular bone in horses with foot pain.
There is an association between distal border fragments and other pathological MRI abnormalities of the navicular bone. Potential relevance: Distal border fragments are part of navicular disease, but their contribution to pain and lameness remains to be clarified. © 2010 EVJ Ltd....
Experimental assessment of nutrition and bone growth's velocity effects on Harris lines formation.
Harris lines (HL) are radio-opaque transverse lines traditionally associated with stressors that halt or decelerate growth in humans. Harris lines' status as a stress marker is, however, questionable because their association to illness and deficient growth is low and they commonly form in the absenc...
Changes in hoof surface strain distribution in response to moderate exercise in Standardbreds.
To quantify changes in hoof wall strain distribution associated with exercise and time in Standardbreds.
A mini-cap for simultaneous EEG and fMRI recording in rodents
We introduce both a new EEG mini-cap and a protocol to obtain whole scalp EEG recordings simultaneously with 7 T fMRI signals in rodents. We provide methodological protocol to evaluate a number of problems emerging from the particulars of using rodents in simultaneous EEG and fMRI recording. The qua...
Type IV Monteggia fracture in a cat.
A one-year-old neutered male cat was referred for a grade IIIA open radius and ulna fracture. The mid-diaphyseal radial and ulnar fractures were associated with lateral radio-humeral and radio-ulnar dislocations. From these abnormalities, a diagnosis of type IV Monteggia fracture was...
