Systems and methods are disclosed for microscale pharmacokinetics. Various organs and their interactions with drug compounds can be simulated in vitro by use of microscale compartments that can be interconnected by microscale channels. Cells or cellular materials associated with the organs can be cultured in such compartments to allow interactions with drug compounds in one or more fluidic flows. Such fluidic systems can include, by way of examples, gastrointestinal flow, blood flow, bile flow, urinary flow, and brain fluid flow. Interactions between fluidic systems can be simulated by a microscale permeable member. In one example, blood-biliary interaction can be simulated by a microscale permeable material having hepatocytes bound to a permeable substrate via a binder.

It is an object of the present invention to provide a combination of a functional assessment of renal function together with biomarker results in order to improve assessment of patient at risk of or having, an acute kidney injury. A loop diuretic such as furosemide inhibits luminal active chloride transport throughout the thick ascending limb of Henle, thereby preventing sodium reabsorption and resulting in natriuresis and increased urine flow. Loop diuretic-induced increases in urine output might be a method to assess the integrity of the renal tubular function in the setting of early AKI, and so a kidney's response, or lack thereof, to a diuretic challenge as a clinical assessment of tubular function can identify patients with severe tubular injury before it is clinically apparent (e.g. a rise in creatinine).

The unique characteristic sounds produced by urine as it impacts the surface of the water in a toilet are used to monitor men's urinary flow pattern and its dynamics. By detecting the intensity at selected acoustic frequencies, it is possible to accurately and precisely measure the urine flow rate. Techniques for analyzing urine flow and its dynamics employ sound levels that are detected at two or more distinct frequency regions or channels of the sound spectrum. One frequency region that is designated the measurement channel is where the sound measurement intensity strongly depends on urine flow levels. Another frequency region that is designated the reference channel is where the sound measurement intensity is not dependent on urine flow levels. By using a combination of measurements from the measurement channel and the reference channel, the urine-flow monitoring apparatus compensates for variations in operating conditions and other factors during use.
