Microvascular basis for growth of small infarcts following occlusion of single penetrating arterioles in mouse cortex.

Small cerebral infarcts, i.e. microinfarcts, are common in the aging brain and linked to vascular cognitive impairment.

Estimation of unsteady aerodynamics in the wake of a freely flying European starling (Sturnus vulgaris).

Wing flapping is one of the most widespread propulsion methods found in nature; however, the current understanding of the aerodynamics in bird wakes is incomplete. The role of the unsteady motion in the flow and its contribution to the aerodynamics is still an open question. In the current study, the wake of a freely flying European starling has been investigated using long-duration high-speed Particle Image Velocimetry (PIV) in the near wake.

Targeted Occlusion of Individual Pial Vessels of Mouse Cortex.

Targeted photothrombosis is a method to occlude individual arterioles and venules that lie on the surface of the cerebral cortex. It has been used to study collateral flow patterns within the pial vascular network following occlusion of single surface vessels (Schaffer ., 2006; Blinder .

Heat Stress and Injury Prevention Practices During Summer High School Football Training in South Texas.

The purpose was to describe practice conditions influencing the risk of heat stress to athletes in summer football training in South Texas high schools, and to compare these conditions to ACSM recommendations for heat stress/injury risk reduction in this population. Thirty (=30) high school summer football practices were observed. Wet bulb globe temperature (WBGT) was measured before/after practices and practices were observed for: duration/structure; athlete clothing; and rest break frequency/duration/content.
