  • Publication number: 20090163933
    Abstract: An ear hair removal instrument including a head, at least a portion of which its outer surface is covered with cold wax. The head is shaped and sized to be receivable in the outer ear while preventing insertion into the middle ear. A handle is mounted at its distal end to the head. In use, the head of the instrument is inserted in the outer ear so that the cold wax disposed on the head comes into contact with the ear hair. While disposed in the outer ear, the ear hair in contact with the cold wax is extracted from its follicles by simultaneously rotating and pulling the instrument.

  • Publication number: 20030032774
    Abstract: This invention relates to opioid peptides, to pharmaceutical compositions containing the peptides, and to methods for controlling pain by administering the peptides or pharmaceutical compositions. The peptides have a high degree of selectivity for the &mgr;-opioid receptor. Although they are highly lipophilic, the peptides do not readily cross the blood brain barrier (BBB). Because the peptides act peripherally, they substantially avoid the side effects associated with central analgesic action.

  • Patent number: 6060451
    Abstract: A thrombin inhibitor comprising a first bulky hydrophobic portion interacting with the catalytic site of thrombin responsible for proteolysis and a second portion at least maintaining the hydrophobic and acidic character of amino acids 55 to 60 of native hirudin at the C-terminal non-catalytic region of N-acetyl-hirudin45-65. Between the first and second portions is a divalent linker moiety having a chain length of at least 10 carbon atoms. Connecting the first bulky hydrophobic portion and the linker is a peptidomimetic bond. Preferably, the bulky hydrophobic portion comprises at least one amino acid of D-configuration. The compounds are useful in the treatment of thrombotic disorders.

  • Patent number: 6057314
    Abstract: This invention relates to the discovery of heterocyclic competitive inhibitors of the enzyme thrombin, their preparation, and pharmaceutical compositions thereof. As well, this invention relates to the use of such compounds and compositions in vitro as anticoagulants and in vivo as agents for the treatment and prophylaxis of thrombotic disorders such as venous thrombosis, pulmonary embolism and arterial thrombosis resulting in acute ischemic events such as myocardial infarction or cerebral infarction. Moreover, these compounds and compositions have therapeutic utility for the prevention and treatment of coagulopathies associated with coronary bypass operations as well as restenotic events following transluminal angioplasty.
