Indeterminate Growth: Could It Represent the Ancestral Condition?

Indeterminate growth paths and stability

Indeterminacy in an economic growth model arises whenever the stable manifold has dimension greater than the number of predetermined initial conditions. The stability (indeterminacy) of transition paths in the Benhabib and Farmer (1996) model of growth is investigated, using both the Lyapunov method and numerical simulation techniques. The sensitivity of transient dynamics is analyzed with resp...

Airway Inflammatory Biomarker: Could It Tailor the Right Medications for the Right Asthmatic Patient?

Asthma is a heterogeneous disease, in which asthmatic patients present with different clinical phenotypes, variable endotypes, and different response to asthma medicines. Thus, we are faced with an asthma paradox; asthma is diagnosed subjectively by clinical history and treated with biologically active drugs. To solve this paradox, we need objective airway biomarkers to tailor the proper medica...

Meiosis: how could it work?

A physical connection between homologs is required for reductional segregation at the first division of meiosis. This connection is usually provided by one or a few well-spaced crossovers. A speculative overview of processes leading to formation of these crossovers is presented.

Could it be Lyme neuroborreliosis?

Subcutaneous emphysema of the leg: Could be a fatal condition

Gas in the leg is not always a gas gangrene. Abdominal infection with gas forming organisms may spread to the thigh & leg. We report a case of critically ill patient who presented to the emergency department with features suggestive of septic arthritis of the left hip. Assessment and further intervention revealed subcutaneous emphysema of the leg secondary to an infection of a previously asympt...
