Systems and methods are provided for processing and analyzing signals reflecting, physiologic processes and events in a monitored subject, especially cardio-pulmonary signals. The input signals are analyzed by in a physiological domain by creating structured data representing the physiological events reflected in the signals. Preferably, first, primitive event objects are created representing physiologically-significant portions of these input signals; second, the primitive event objects are grouped into primary event objects representing actual physiologic processes and events. Next, all objects are stored in databases, and organized in containers for efficient searching. Information may be retrieved by creating view objects which associate physiologic event objects having selected properties specified directly in physiological terms. This invention includes methods for performing the above analysis, systems and program products for carrying out these methods, and databases configured with the stored objects and views.

A systems biology approach is used to characterize and relate the intestinal (gut) microbiome of a host organism (e.g. a human) to physiological processes within the host. Information regarding the types and relative amounts of gut microflora is correlated with physiological processes indicative of e.g., a patient's risk of developing a disease or condition, likelihood of responding to a particular treatment, for adjusting treatment protocols, etc. The information is also used to identify novel suitable therapeutic targets and/or to develop and monitor the outcome of therapeutic treatments. An exemplary disease/condition is the development of hepatic encephalopathy (HE), particularly in patients with liver cirrhosis.

The present invention is the universal unmedicamental system to treat the snore and obstructive sleep apnea and recover of the normal breathing during sleep. The invention includes the device, which ensures the fixation of the tongue in a putting forward beyond the mouth position. As a result, the tongue's pharyngeal part pushes forward in the mouth, releasing besides the throat and excluding the tongue from a system of obstruction to the air's passing through the throat. This increases the throat's capacity, depriving the other throat's structures of the possibility to provoke the partial or complete obstruction to the air's passing through the throat during the physiological process of breathing in the time of the sleep.
