    摘要: The present invention relates to improved diagnostic methods for early detection of a risk for developing type 2 diabetes mellitus in humans, and screening assays for therapeutic agents useful in the treatment of type 2 diabetes mellitus, by comparing the levels of one or more indicators of altered mitochondrial function. Indicators of altered mitochondrial function include enzymes such as mitochondrial enzymes and ATP biosynthesis factors. Other indicators of altered mitochondrial function include mitochondrial mass, mitochondrial number and mitochondrial DNA content, cellular responses to elevated intracellular calcium and to apoptogens, and free radical production. Methods of treating, and of stratifying, human patients as such methods relate to disclosed indicators of altered mitchondrial function are also provided.

    摘要: The present invention relates to genetic mutations in mitochondrial genes that segregate with diabetes mellitus. The invention provides methods for detecting such mutations, as a diagnostic for diabetes mellitus, either before or after the onset of clinical symptoms. Examples of specific mutations in the ATP synthase 8/6 sequence and tRNALys sequence are given. The invention also provides treatments for dysfunctions due to genes for mitochondrial functions that segregate with diabetes mellitus. Cybrid cell lines are described which are useful as model systems for the study of the mitochondrial metabolic disorders that are associated with diabetes mellitus, and for identifying therapeutic compounds and treatments for this disease.

    摘要: A specimen support for optical observation or analysis. The support comprises a disc-like member composed of a rigid material and having at least one unobstructed hole extending therethrough. When analyzing a liquid specimen, the disc is dipped in the liquid and the surface tension of the liquid will cause the liquid to bridge or span the hole. The support is then placed in a tray or holder and exposed to an infrared beam to generate an infrared spectrum.

    摘要: Tamper proof service bolts for sealing boxcars, automobile hoods, gates and other enclosures, as well as gas and electric meters, railroad switches and the like. In a first preferred embodiment the tamper proof service bolts are characterized by special head service bolts, each having a base member and a collar secured to the base member by means of a connecting bolt having a specialized head recess for receiving a corresponding tool which is required for removing the connecting bolt and the collar from the base member. In another preferred embodiment of the invention retainer clip service bolts are provided, wherein a retainer clip is adapted to mount on each base member and in the collar when the collar is fitted over the base member, to secure the collar on the base member. In still another preferred embodiment a sacrifice head service bolt is provided where the collar is fitted on the base member and a sacrifice head having a thin, frangible neck is threaded on the base member, such that the bottom element of the sacrifice head is countersunk in the collar when the top element of the sacrifice head is stripped from the bottom element at the frangible neck. A cross-thread nipple service bolt is also provided, wherein the base member is fitted with an upward-standing, threaded stud for engaging dissimilar threads in a cross-thread collar such that the threaded nipple is irreversibly cross-threaded into the cross-thread collar.

    摘要: A tamper-proof valve which includes a valve body fitted with a transverse bore, an entry port and outlet port communicating with the transverse bore and an inner body seat for receiving a tapered inner body having a notch adapted for manipulation in alignment with the entry port and outlet port in open configuration and transverse to the entry port and outlet port, in closed configuration. A plug is provided on the top of the inner body for seating one end of a spring which is slidably encased in a collet. A square key is also slidably disposed in one end of the collet and is adapted to seat in a key seat provided in a top valve assembly which mounts on the valve body. An allen screw having a tamper-proof tool receptacle is threaded in the top valve assembly in alignment with the key, such that a special tool may be inserted in the allen screw tool receptacle and the allen screw rotated in the clockwise direction (when viewing the valve body from the top) to seat against the key, compress the spring inside the collet, remove the key from the key seat located in the top valve assembly and facilitate rotation of the top valve assembly independently of the inner body. Rotation of the allen screw in the opposite, or counterclockwise direction allows the spring to force the key upwardly into the key seat and facilitate opening and closing the inner body and the valve body in concert.
