Abstract: A smoke detector system includes a smoke detector sensor and oxygen sensor mounted to a housing.

Abstract: A sensor apparatus includes a metal oxide semiconductor (“MOS”) sensor with a gas-sensing surface normally having a first sensitivity to a first species of flammable gas and a second sensitivity to a second, different species of flammable gas. A selective sensitivity-enhancement layer is disposed on the gas-sensing surface such that the first sensitivity becomes increased and the second sensitivity remains substantially unchanged.

Abstract: A sensor apparatus includes a metal oxide semiconductor sensor and a housing having an internal chamber in which the sensor is disposed. The housing includes at least one window for the ingress of a gas into the internal chamber from an atmosphere exterior to the housing. A gas-selective barrier is disposed across the at least one window.

Abstract: A fire detection system includes a detection tube and a sensing device. The detection tube contains a sensing fluid having a first physical condition and a second physical condition. The sensing fluid is in the first physical condition below a temperature threshold, and is in the second physical condition above the temperature threshold. The sensing fluid is at least partially liquid in the first physical condition. The sensing device is movable to open in response to a transition of a portion of the sensing fluid from the first physical condition to the second physical condition.

Abstract: A fire suppression cylinder includes a valve at an outlet of a canister, and a control for the valve. The canister receives a liquid suppressor agent and a pressurized gas. A feature within a portion of the canister will receive the liquid suppressor agent. The feature increases the formation of gas bubbles within the liquid suppressor agent.

Abstract: Prostate cancer comes in various forms and has proven difficult to treat. Provided herein are various methods and compositions for treating all forms of prostate cancers with dopa decarboxylase (DDC) inhibitors. These dopa decarboxylase inhibitors include carbidopa (?-Methyl-dopahydrazine), MFMD (?-monofluoromethyldopa), NSD-1015 (3-hydroxybenzylhydrazine), Methyldopa (L-?-Methyl-3,4-dihydroxyphenylalanine) or benserazide, and the inhibitors may be used in combination. DDC inhibitors may also be used to inhibit the progression of prostate cancer to androgen-independence and neuroendocrine prostate cancer.

Abstract: It has now been determined that antisense therapy which reduces the expression of TRPM-2 provides therapeutic benefits in the treatment of cancer. In particular, such antisense therapy can be applied in treatment of prostate cancer and renal cell cancer. Addition of antisense TRPM-2 ODN to prostatic tumor cells in vivo is effective for delaying the onset of androgen independence. Thus, prostate cancer can be treated in an individual suffering from prostate cancer by initiating androgen-withdrawal to induce apoptotic cell death of prostatic tumor cells in the individual, and administering to the individual a composition effective to inhibit expression of TRPM-2 by the tumor cells, thereby delaying the progression of prostatic tumor cells to an androgen-independent state in an individual Combined use of antisense TRPM-2 and taxanes synergistically enhances cytotoxic chemosensitivity of androgen-independent prostate cancer.

Abstract: The present invention is directed to compositions that are useful in the prevention and treatment of common cold and influenza-like symptoms due to respiratory tract viral infections. These compositions comprise a guaiacol component, and a mucoadhesive polymer wherein the pH of the composition is about 5.5 or less.

Abstract: The present invention provides anti-microbial foam dispensing hand-sanitizer devices. The devices provide ease and convenience of use, require no water for use, and have improved residue reduction. Also provided are kits and methods of use.

Abstract: The present invention is directed to methods of preventing and treating respiratory tract viral infections by administering compositions to areas of the respiratory tract such as the nasal cavity, wherein the compositions provide for the encapsulation, inactivation, and/or removal of viruses and/or viral strains associated with the common cold and influenza. The methods of encapsulation, inactivation, and removal of cold and influenza viruses have been shown to create and maintain environments that are hostile to the viruses to result in effective prevention and treatment of cold and influenza-like symptoms.

Abstract: An automatic chromosome analysis system is provided wherein a suitably prepared slide with chromosome spreads thereon is placed on the stage of an automated microscope. The automated microscope stage is computer operated to move the slide to enable detection of chromosome spreads on the slide. The X and Y location of each chromosome spread that is detected is stored. At the conclusion of this searching operation, the computer directs the microscope to again sequence through the chromosome spread locations in response to the stored X and Y locations. At this time an operator can view these spreads to determine which ones are worthwhile and which ones are not. He is provided with an accept-reject switch. The microscope stage thereafter again sequences through only the accepted chromosome spreads, and this time a digital photograph of each of the chromosome spreads is made and entered into the computer storage.
