A method and apparatus for transporting radiopharmaceuticals. Typically, the apparatus is a two-part assembly, each part having an exterior shell, a radiation shield and a non-porous lining. Additionally, the assembled apparatus has a sealed internal chamber suitable for carrying a syringe or a sharps container containing a syringe. The internal chamber of the radiopharmaceutical pig is lined with a non-porous lining, typically a durable plastic, that prevents contamination of the radiopharmaceutical doses, the radiation shield, or the environment. Additionally, the non-porous lining can be quickly and easily cleaned and sterilized, avoiding the often difficult, to impossible, task of cleaning and sterilizing the radiation shield of the radiopharmaceutical pig. The non-porous lining is surrounded by a radiation shield that is typically comprised of elemental lead. The radiation shield prevents radiation from the radiopharmaceutical from contaminating the user or environment. The radiation shield is surrounded by an exterior shell that absorbs impact and prevents the radiopharmaceutical pig from breaking. Additionally, the exterior shell prevents environmental exposure to the potentially hazardous material of the radiation shield. Generally, a method of transporting a radiopharmaceutical by filling the container with a radiopharmaceutical, inserting the container into the internal chamber of the radiopharmaceutical pig having a non-porous lining, and assembling the radiopharmaceutical pig so the that the container is in the internal chamber and is encapsulated by the radiation shield, is also provided.

An environmentally sound apparatus and method for automatically extracting fluids such as lubricating fluids from a target reservoir such as a crankcase for a vehicle engine, and injecting the proper type and quantity of fresh fluid into the reservoir is disclosed. The apparatus includes one or more sources of lubricating fluid, a waste fluid tank, a pump, and a flow meter. A programmed microprocessor produces selected sequences of control signals to govern the flow of fluid among the fluid sources, the waste fluid tank, and the target reservoir in response to input identification information and signals produced by a flow monitoring pulse meter. Input identification information is compared with data in a stored database to determine the correct type and quantity of fresh fluid to inject. Operator identification information is compared with a stored operator database to determine what operations each operator is permitted to perform. A display and selection switches allows the operator to select from different procedure options. Evacuation, injection and clearing operations are initiated by an operator and executed automatically through status monitored sequences controlled by the microprocessor. All fluid exchange sequences are performed without exposing the operator or the environment to either waste or fresh fluid.

A biodegradable, bio-compatible material is described for use in wireless biosensors for point-of-care applications. The biosensor made from this biomaterial is capable of sensing environmental effects and as well as presence of bio-logical entities in the environment of concern simultaneously. Such a sensor can be used for evaluating point-of-care environmental preparedness for a specific patient through continuous monitoring of patient health performance due to environmental exposure. A two-tier network architecture is established for real-time monitoring (static case) that also provides warning of accumulated exposure. Wavelet analysis can be used to identify anomalies in the sensed data to initiate a warning.

Sets of genes are identified that show modulated activity in hyperpigmented sun-exposed (HE) and non-hyperpigmented sun-exposed (NHE) skin, when compared to non-hyperpigmented non-exposed (NHNE) skin. The modulated sets of genes reveal important information about the genetic changes that take place in skin as a result of environmental exposure and damage. The modulated sets of genes may be used to fabricate custom DNA microarrays for evaluating patients with skin diseases or disorders. The microarrays may also be used to screen new substances for treating skin diseases and disorders. The modulated gene sets, and substances that target them, may also be used to develop therapies for individuals who suffer from hypopigmentation, such as those with Fitzpatrick type I skin or vitiligo.

A test method that helps identify foods that may be causing a reaction in an individual involves the individual entering into a computer a daily log of all the foods they routinely eat and any reactions that they may experience. The reactions may be headaches, fatigue, physical pain, depression, etc. The test method can be done without the individual having to follow any prescribed diet. After recording several weeks or months of data, the computer analyzes the data to determine if any significant mathematical correlations exist between a reaction and any of the foods, whereby a high positive correlation may suggest that the food is perhaps related to the reaction. In addition to food items, the method can analyze the correlation of other influencing agents such as environmental exposures, inhalants, menses, and stress.
