Therapeutic Targeting of Arteriogenesis Following Ischemic Stroke
… leads to long term neurological deficits. Pial collaterals are a well-established determinant of patient outcome due to their unique ability to remodel into conductance arteries that can reroute blood back to the ischemic tissue. During development, pial collaterals arise within the pia mater …

Vascular Reactivity in Newly-Formed and Mature Arterialized Collateral Capillaries
… segments can arterialize and form functional collaterals following an ischemic event; however, in the early stages of development, vasodilation is impaired. We explored the mechanism of impaired vasodilation in arterialized collateral capillaries (ACCs) and pre-existing collaterals (PECs) by …

Mathematical Models of Major Arterial Occlusion
… artery occlusion and the role of leptomeningeal collaterals in restoring flow downstream of the occlusion. The effects of incorporating pulsatile blood flow and arterial distensibility are also examined. The model demonstrates that the leptomeningeal collaterals are critical to restoring blood …

An Electrophysiological Analysis of the Primary Input to the Cat Prepyriform Cortex
… supports the anatomical work of others showing collaterals leaving the tract to synapse with cortical cells, with the main axon sending collaterals along the length of the tract (divergence). Neurons were also activated with similar thresholds at points across the tract trajectory, indicative of …

From space to episodes : modeling memory formation in the hippocampal-neocortical system
… impose activity patterns on CA3, and recurrent collaterals and perforant path inputs are subject to graded Hebbian plasticity. Attractors are thus sculpted in CA3, and are associated with entorhinal activity patterns. In familiar environments, place fields are controlled by the way that …

The Contribution of Microfinance Institutions to Poverty Reduction at South District In Zanzibar
… to issue loans to needy potential customers and collaterals shouldn’t act as barrier. It was further recommended that MFIs need empowerment initiatives including special tax incentives, business and entrepreneurship skills, and special policies that focus to empower in providing loans to …

An Assessment of increased household income through the production of leather shoe for Umoja savings group at Mchikichini mtaa - Ilala municipal council Dar-es-salaam region.
… cannot meet the bank requirements including the collaterals applied. The project in this case the production of leather shoes, has increased the group income which were obtained after selling of the shoes. The project also attracted and retained customers and also promoted brand image for …

Small and Medium Enterprises Defaults’ in Commercial Banking in Tanzania:Case study in CRDB Bank (PLC)
… measures are going to be imposed against their collaterals pledged as security in their loans. Loan granting process is a procedure, where by all applicants have to follow all necessary procedures before loans are granted to them. Procedures are including but not limited to; to have business …

The Role of Age and Model Severity on Cortical Vascular Response Following Traumatic Brain Injury
… specialized network of arteriole vessels, called collaterals after trauma. We demonstrated that a repetitive mild TBI (rmTBI) can induce collateral remodeling in C57BL/6 but not CD1 mice; however, CCI injury had no effect on collateral changes in either strain. Together, these findings demonstrate …

Measurement of the effectiveness of enhanced external counterpulsation on heart rate variability for patients with myocardial ischemia
… formation of, small branches of blood vessels (collaterals) to create a natural bypass around narrowed or blocked arteries. It has been proved that rhythms can be markers of normal functional states. Even in the absence of external perturbations, the normal heartbeat is not characterized by …

Major Collateral Vessels Develop from Pre-existing Small Arteries through RAC2/NOX2 Independent Mechanisms
… collateral vessels in each species, these major collaterals displayed characteristics similar to large arteries experiencing flow-mediated outward remodeling, and important differences in vascular wall thickness were observed between rodents and pigs. Chapter II utilized Rac2-/- and Nox2-/- mice …

The Impacts of Arterial Occlusion, Sex, and Exercise on Arteriogenesis and Functional Vasodilation
… occlusion is not well defined, but immature collaterals may demonstrate impaired vasodilation in animal models, although this is potentially improved with exercise training. Furthermore, as females exhibit poorer physical function with ischemia and less improvement with therapeutic exercise, …

Circuit Dynamics of Adult Visual Cortex
… following weeks, the massive increase in axon collaterals was accompanied by a comparable rate of axonal elimination. Also, boutons increased their rate of appearance and elimination beyond the rates seen in normal cortex. These data indicate that the initial sprouting of axons followed by the …

ELECTROPHYSIOLOGICAL ANALYSIS OF THE RECURRENT RENSHAW CIRCUIT
… cord which includes recurrent motoneuronal collaterals, Renshaw cells and other interneurons, which, in turn, project to motoneurons. The project describes the use of a relatively new data processing technique, spike-triggered averaging, to study the effects of the single impulses of single …

Dynamic and Integrative Properties of the Primary Visual Cortex
… changes in the network of horizontal collaterals. The reorganization accompanies the brain's amazing ability to perceptually "fill-in", or "see", the lost visual input. We developed a computational model to simulate cortical reorganization and perceptual fill-in mediated by a plexus of …

Eph-mediated restriction of cerebrovascular arteriogenesis
… expression on ECs suppress the formation of pial collaterals during development and limits EC growth via suppression of p-Akt in vitro (2) EC-specific EphA4 ablation leads to increased collateral remodeling, enhanced blood flow recovery, tissue protection and improved neurological behavioral …

Neural processing of chemosensory information from the locust ovipositor
… eighth abdominal neuromere with some of their collaterals ascending to more anterior abdominal ganglia. The projecting interneurons of these respond only to one or two chemical substances (sugars or salts, or salts and acids together) with excitatory or inhibitory responses. The physiological …

Metamodeling Driven IP Reuse for System-on-chip Integration and Microprocessor Design
… IPs at all abstraction levels, and verification collaterals such as testbenches, simulators, and coverage monitors can be generated from these models, thereby enhancing reuse in verification.

Machine learning models for functional impairment risk prediction in ischemic stroke patients
… data from the Precise and Rapid Assessment of Collaterals with Multi-phase CT Angiography (PROVE-IT). The Modified Rankin Scale (mRS) score was used to assess the 90-day functional impairment status. The accuracy of machine-learning models such as random forest (RF), classification and …

The Impacts of Sex and Myogenic Cell Transplantation on Collateral Capillary Arteriogenesis
… treatments. Because patients with native collaterals have a better prognosis, promoting collateral arteriogenesis is a potential PAOD treatment. Additionally, female PAOD patients have a worse response to treatment and a worse prognosis compared to males, which could be due to impaired …
