Morphological scaling relationships capture and describe organismal shape. We present a method to measure morphological scaling relationships across the natural range of body sizes in fully metamorphic insects. Using a simple diet manipulation we increase the distribution of trait sizes, permitting the accurate description of how shape and size co-vary.

Assessing Phagocytic Clearance of Cell Death in Experimental Stroke by Ligatable Fluorescent Probes

We present a new fluorescence technique for selective in situ labeling of active phagocytic cells, which clear off cell corpses in stroke. The approach is important for assessing brain reaction to ischemia because only a small proportion of phagocytes present in ischemic brain participate in clearance of cell death.

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Various murine models of middle cerebral artery occlusion (MCAO) are widely used in experimental brain research. Here, we demonstrate the model of transcranial permanent distal MCAO which produces consistent cortical infarction of a size corresponding to damage imposed by the majority of human ischemic strokes.

FAQs
The scale converts several observable neurological signs into standardized scores, reducing reliance on broad verbal descriptions such as “mild” or “severe” impairment. Assessing posture, movement, limb use, and coordination in a structured way allows researchers to compare animals, injury conditions, and treatment groups more consistently. This reproducibility strengthens interpretation of behavioral differences after cerebral ischemia or hemorrhage.
Posture, spontaneous movement, limb use, and coordination capture different aspects of neurological dysfunction. Abnormal posture may indicate asymmetric impairment, whereas reduced movement reflects broader functional limitation. Impaired limb use and poor coordination add information about motor control. Considering these domains together provides a more informative profile than relying on a single observable sign.
A behavioral score shows how neurological injury affects observable function, but it does not by itself identify the underlying tissue or molecular changes. Histological analysis can relate behavior to tissue damage, while imaging and molecular analyses provide complementary evidence about the injured brain. Combining these measurements helps researchers determine whether functional changes correspond to biological injury and treatment effects.
The magnitude of observed deficits provides an indication of functional impairment, while changes in scores over the course of an experiment can indicate recovery or persistent disability. Comparing behavioral results across animals or treatment groups helps reveal whether an intervention is associated with improved function. Interpretation remains strongest when score changes are evaluated together with tissue, imaging, or molecular findings.
After cerebral ischemia or hemorrhage is produced in an animal model, researchers assess the specified observable neurological signs, including posture, movement, limb use, and coordination. They then assign standardized scores and compare results across injury or treatment groups. This behavioral dataset can subsequently be related to histological, imaging, and molecular measurements to evaluate functional consequences and recovery.
The scale is useful when researchers need a functional outcome for judging whether an intervention changes neurological impairment after experimental stroke. Neuroprotective treatments can be evaluated through differences in behavioral deficits, while rehabilitative interventions can be examined through evidence of improved function over time. Relating these outcomes to brain injury measurements also helps assess translational potential.
