Muscular measuring stick
N ebulin acts as a measuring stick for the thin actin fi laments in muscle, say Bang et al. (page 905). Longer thin fi laments result in greater overlap with myosin thick fi laments and thus the ability of a muscle to bear greater loads. Distinct muscles have different biophysical properties and requirements, and the lengths of the many nebulin iso-forms have been suggested to correlate with th...
متن کاملMeasuring symmetry of moving stick creatures
This work summarizes various approaches to measuring symmetry of static and moving creatures. It outlines some problems with estimating symmetry of moving creatures: determination of the temporal direction of movement, aggregation of changing lifespan symmetry to a single value, and indeterminism of computer simulations.
متن کاملNew international measuring stick for defining obesity in non-Europeans.
Body mass index (BMI) is a useful way of classifying the degree of excess weight in an individual. Defining BMI cut points at which adverse cardiovascular outcomes, diabetes mellitus, and other comorbidities are more likely to occur affords clinically relevant guidelines for patient care. Expert panels from both the National Institutes of Health and the World Health Organization1–3 have develop...
متن کاملReceptor protein tyrosine phosphatase μ : measuring where to stick
We review here recent results on the structure and function of a receptor protein tyrosine phosphatase, RPTPμ. In addition to their intercellular catalytic domains which bear the phosphatase activity, the RPTPs are cell-surface-receptor-type molecules and in many cases have large extracellular regions. What role can these extracellular regions play in function? For RPTPμ, the extracellular regi...
متن کاملSepsis and the theory of relativity: measuring a moving target with a moving measuring stick
Sepsis is the subject of intense interest for clinicians, policy makers, patients, and researchers. Stakeholders around the world are striving to improve sepsis awareness and quality of care. The Surviving Sepsis Campaign, World Sepsis Day, and mandatory reporting rules are but a few examples of ongoing initiatives. All sepsis stakeholders need accurate data on sepsis incidence, characteristics...
