Abstract: A portable electronic device may include a housing having a wall defining an opening in the housing and at least a portion of four side surfaces of the portable electronic device. The portable electronic device may further include a display at least partially within the housing, a front cover positioned in the opening in the housing and over the display, the front cover defining a front surface, a peripheral side surface extending from the front surface and at least partially surrounded by the wall of the housing, and a notch that, together with a portion of the wall of the housing, defines an acoustic port of the portable electronic device. The electronic device may further include an acoustic port cover positioned at least partially in the acoustic port and a speaker at least partially within the housing and configured to direct sound through the acoustic port cover.

Abstract: Methods are provided for detecting levels of low oxygen in a tissue of a mammalian subject by administering non-polar halogen compounds to the mammalian subject. Detection may be accomplished using imaging methods involving fluorescence immunohistochemical imaging of the halogen compound.

The invention further presents monoclonal antibodies highly specific for the claimed nitroaromatic compounds, the compounds' protein conjugates, the compounds' reductive byproducts, and adducts formed between the compounds and mammalian hypoxic cell tissue proteins. The invention is further directed to methods for detecting tissue hypoxia using immunohistological techniques, non-invasive nuclear medicinal methods, or nuclear magnetic resonance. Diagnostic kits useful in practicing the methods of claimed invention are also provided.

Abstract: The invention relates to the discovery that the concentration of free cysteine in mammalian tumor tissue is elevated compared with the concentration of free cysteine in non-tumor tissue of the same origin. Elevated levels of free cysteine is, in turn, correlated with resistance of tumors to antitumor therapy such as chemotherapy and radiation therapy. Therefore, the invention further relates to methods of detecting the presence of tumors in mammalian tissues, assessing the resistance of tumors to antitumor therapies as it relates to free cysteine concentration, and to the identification of compounds which affect free cysteine concentration in mammalian tissues.
