Abstract: Use of a disposable filtration capsule with a non-occluded membrane filter element in the place of a standard spiral wound cartridge allows for the more rapid and quantitative filtration, recovery, and quantitation of microorganisms in liquid, particularly surface waters, well water, tap water, and the like. The capsule allows a severe reduction in the water sample size tested, substantially minimizes risks of cross-contamination, and provides a leak-proof vessel for shipment. Risks of infection of laboratory personnel and time of analysis are both reduced. Costs of measuring contamination by microorganisms such as Giardia and Cryptosporidium is lowered significantly while increasing the accuracy and dependability of the measurement.

Abstract: New herbicidal active substance combinations consist of (a) an arylsulphonylaminocarbonyltriazolinone of formula (I), in which R1, R2, R3 and R4 have the meanings given in the description, and/or a salt of a compound of formula (I) ("active substance of group 1"); and (b) one or several compounds from a second group of certain known herbicides ("active substance of group 2"). These combinations show synergistic effects at certain weight ratios and may be used as selective herbicides in various useful plant cultures. Typical examples are active substance com-binations of the Na salts of the compounds of formula (I) wherein R1 = CH3, R2 = OC3H7, R3 a COOCH3, and R4 = H(I-1) or R1 = CH3, R2 = OCH3, R3 = OCF3 and R4 = H(I-2) as active substance of group I and metribuzin as active substance of group 2.

Abstract: The invention relates to cellulose fluff pulp products that are debondable into fluff with markedly lower energy input, to a process for making the products, and to absorbent products using the fluff. Most of the pulp products show no reduction in liquid absorbency rate from that of untreated fiber and significantly higher rates than pulps treated with the usual debonding agents. The products are made by adhering fine noncellulosic particles to the fiber surfaces using a retention aid. The fiber is preferably treated with the retention aid in an aqueous suspension for a sufficient time so that the retention aid is substantively bonded with little or none left free in the water. The fine particulate additive is then added and becomes attached and uniformly distributed over the fiber surfaces with very little particle agglomeration occurring. The fiber is most usually not refined or only very lightly refined before sheeting. However, it may be significantly refined to produce a product having a very high surface area. Kaolin clay is a preferred particulate additive. The treated pulp may be mixed with other fibers before sheeting or after it is debonded into a fluff. The fluff is highly advantageous in the absorbent portions of personal care products such as diapers or sanitary napkins.

Abstract: Various skin disorders, excluding acne are treated by topical application to the skin of a retinoid-composition including a retinoid in a dermatologically acceptable vehicle at such a concentration and applied in such a way as to induce desquamation of the skin to ameliorate the disorder. Preferably, the compositions contain greater than 0.1 weight percent tretinoin, and more preferably at least 0.2 weight percent tretinoin. The vehicle is preferably a solvent for the retinoid such as an alcohol/glycol or hydroalcoholic vehicle, but it is also possible to apply the retinoid in a non-solvent vehicle such as emulsifying or suspending the retinoid in a cream, dressing, gel, ointment or liquid polymer, with or without penetration enhancers. The treatment achieves rapid amelioration of skin disorders such as photodamaged skin, hyperpigmentation, rosacea, premalignant cancers including actinic keratoses , wrinkles, superficial scarring, epidermal atrophy and atypia, and keratosis pilaris, by daily or every other day application for about one to two months. Thereafter, the high strength applications may be tapered off, and the treated skin maintained with more conventional lower concentration compositions.

Title: Method for using an elevator installation
Inventor: FRIEDLI PAUL
IPC: B66B1/46
Filed: 2000-01-25
Granted: 2007-10-02
Abstract: This device allows an implicit or explicit input of destination calls on elevator installations. After a corresponding inquiry by a detector (5), an information transmitter (1) transmits data (6). This data (6) can contain direct information about the desired destination floor and/or serve as identification of the elevator user and thereby enable access to information about the destination floor which is stored in a memory (8). The memory (8) is contained in a processing unit (9) of an elevator control (10). Communication between the detector (5) and the information transmitter (1) takes place, for example, without contact. Using the received data (6) the destination floor is evaluated in the processing unit (9) and communicated to the elevator control (10). The assignment is communicated to the passenger on a display (18). The process of inputting a call takes place automatically and independent of the orientation of the information transmitter (1). To change the floor proposed by the processing unit (9) an input device (19) is provided which can also be used to choose the type of preselection of the destination floor.

Title: Targeted liposome gene delivery
Inventor: CHANG ESTHER H
IPC: C12N15/88
Filed: 1998-11-19
Granted: 2011-07-19
Abstract: Targeted ligand-liposome-therapeutic molecule complexes (vectors) for the systemic delivery of the therapeutic molecule to various target cell types including cancer cells such as squamous cell carcinoma of the head and neck, breast and prostate tumors. The preferred ligands, folate and transferrin, target the liposome complex and facilitate transient gene transfection. The systemic delivery of complexes containing DNA encoding wild-type p53 to established mouse xenografts markedly sensitized the tumors to radiotherapy and chemotherapy. The combination of systemic p53 gene therapy and conventional radiotherapy or chemotherapy resulted in total tumor regression and long term inhibition of recurrence. This cell-specific delivery system was also used in vivo to successfully deliver, via intravenous administration, small DNA molecules (oligonucleotides) resulting in chemosensitivity and xenograft growth inhibition. Other therapeutic molecules, including intact viruses, can be encapsulated in a complex and targeted in accordance with the invention.
