Oxycodone formulations are provided which produce substantially flat in vivo steady state plasma profiles. Tolerance levels associated with such profiles and tolerance levels associated with biphasic profiles are shown not to be statistically different. The substantially flat in vivo steady state plasma profiles are produced by dosage forms having substantially zero order in vitro release profiles. Such release profiles produce low single dose in vivo C_max levels which can reduce the probability of adverse side effects.

Skin conditioning compositions comprising a C4 to C30 monoalkyl-, dialkyl, monoalkanoyl- or dialkanoyl-substituted isohexide are found to exhibit a marked effect on skin hydration and barrier function homeostasis thereby improving skin appearances.

The invention specifies a method and system for leading a person suffering from “sympathetic predominance”, a specific symptom of which is “hypertension”, to breathe according to a certain pattern for the express purpose of positively altering the condition of sympathetic predominance (over activation), having the effect of bringing the autonomic nervous system into the state of balance, with consequent reductions in “tenseness”, blood pressure, muscular tightness, and emotional strain, as well as the alleviation of the myriad of subtle neuro-physiological consequences resulting from sympathetic predominance potentially including headaches, anxiety, sleep disorders, allergies, and other maladies that have yet to be attributed to this condition, thus leading to a general improvement in health, well being, and homeostasis. It accomplishes this by systematically reducing the breathing frequency with consequent increases in breathing depth, the ultimate goal being the realization and ongoing maintenance of 1 complete breathing cycle in 11.76 seconds or 5 complete breathing cycles in 58.8 seconds, the result being improved health, well being, and homeostasis.

A three-dimensional (3-D) culture “Petri-dish” for research in regenerative medicine, biotechnology and clinical translation is described. This 3-D perfusion culture dish is to advance in vitro culture tools from static 2-D to dynamic 3-D perfusion culture. Interwoven hollow fiber capillary membranes divide the “Petri-dish” culture space into a controllable 3-D pattern of different compartments, serving the functions of the organ's larger vasculature. These physically active scaffolds, which can be suitable for cell adhesion or cell aggregate immobilization, offer a supply of cells with high-performance mass exchange including gas supply and under perfusion conditions. In contrast to static and discontinuous medium supply, a dynamic culture can be achieved with continuous or alternating medium supply and integral oxygenation. They provide a more physiologic supply in the cell macro environment, including homeostasis of oxygen, pH, nutrition, soluble factors, and gradients of metabolites for the cells. Also, medium perfusion can be achieved. Consequently the invention was made for cultures at tissue density, especially stem cells and support cells, which strive to create their own stem cell niche.

Methods and compositions are provided for the protection of normal cells from cytoreductive therapy that target proliferating cells, by administering an inhibitor of Wnt signaling pathways. Wnt signaling is critically important for homeostasis of the epithelial lining of the adult intestine and other proliferating normal adult tissues.

An NMDA antagonist (such as ketamine) is administered with a safener (such as clonidine) in patients suffering from neurologic disorders other than pain. The ketamine is adminsitered at a dosage that causes slurred speech, for a span of several days. This treatment enables a patient's nervous system to return to a healthy “set point”, also called an improved stable neural homeostasis, in a manner similar to a broken bone healing itself if protected from jostling and reinjury by a cast. In at least some patients, this treatment can ease problems such as addictions to illegal or pain-killing drugs, nicotine, or alcohol, compulsive or criminal behavioral problems, severe depression, obsessive-compulsive disorders, phobias, etc. It may also provide some relief in some patients for problems such as chronic fatigue, chemical sensitivities, allergies, autoimmune disorders, and diabetes.

Ischemia-reperfusion injury commonly results from any surgical procedure requiring stopping of blood supply to an organ followed by reperfusion such as in heart bypass, angioplasty or organ transplant. The invention discloses a method to harness the innate power of repetitive transient ischemia in protecting organs against imminent ischemia-reperfusion, or any patho-physiological insults. This method of optimal remote ischemic preconditioning (ORIP) comprises of utilizing a pair of programmable pneumatic cuffs that inflate/deflate alternately occluding blood circulation to each of the limbs for pre-defined time intervals. The apparatus delivers maximal ORIP dose in shortest possible time either as an EMS procedure during patient transportation to hospital, as elective pre-surgery treatment, or in critical care for preventing multiple-organ-dysfunction-syndrome. ORIP can be self-administered and remotely monitored by clinician especially in chronic patients for homeostasis of malfunctioning target organs. ORIP may also be deployed as adjunct in angioplasty, gene/stem cell heart repair therapies.

The ANS of a subject is continuously monitored to obtain the sympathetic nervous system (SNS) and parasympathetic nervous system (PSNS) components of the autonomous nervous system while an external stimulus is applied to the subject having a frequency that sweeps across a frequency band. The stimulus may be a vibration, flickering light or sound. The ANS is determined to have entered into a state of homeostasis when the SNS component equals the PSNS component. The value of frequency that corresponds to the state of homeostasis is selected as the fundamental frequency of the subject for use in subsequent treatment protocols.

Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of alerting a user associated with an infusion device delivering fluid to the body of the user involves obtaining a measurement value for a physiological condition being influenced by the fluid, obtaining a current amount of active fluid in the body of the user, determining a homeostasis metric based at least in part on the current amount of active fluid and the measurement value for the physiological condition, and generating an alert based at least in part on the homeostasis metric.

Disclosed are embryoid bodies having a uniform size of approximately 415 nm and comprising genetically modified embryonic stem cells, and methods of making same. The genetically uniform embryoid bodies can be multiplexed as one embryoid body per well in a multiwell format, and used as a high to medium throughput screen for test agents that affect the development and homeostasis of animals, including humans. The genetic modification of the embryonic stem cells is a promoter-report-selection construct that enables the selection and detection of cells of a particular lineage in the EB, to determine the effects of a test agent.

The invention discloses a method for measuring liquid thermal conductivity coefficient and the device thereof. The invention adopts homeostasis hotline principle to measure liquid thermal conductivity coefficient. The calculation formula of the liquid thermal conductivity coefficient is used when different heat sources are applied under the condition of one dimensional conduction respectively deduced by Fourier heat conduction basic law. Then the heat generated by the heating resource which is transmitting heat. And the liquid thermal conductivity coefficient is calculated by measuring the temperature difference at particular points in heat conduction direction when heat balanced. High-temperature resistant coaxial double-layer pipes are used as outer pipes while heat stable heating tube used as inner pipes. Liquid to be measured is packed in the space between the inner and the outer pipes. The ratio of the length of the outer pipe to the external diameter of the outer pipe exceeds is greater than 10. The way of heating of the inner pipe adopts constant-temperature and uniform-speed circulating water or tempering wire and filled with high temperature resistant liquid at the same time. The former is suitable for common liquid and the latter for high temperature flammable liquid. The invention has the advantages of simple structure, large serviceable range and high accuracy rating, thus measuring the coefficients of heat conductivity of various liquids simply and precisely is possible.
