摘要:
Macrolide resistance associated with macrolide efflux (mef) in Streptococcus pneumoniae has been defined with respect to the genetic structure and dissemination of a novel mefE-containing chromosomal insertion element. The mefEgene is found on the 5′-end of a 5.5 kb or 5.4 kb insertion designated mega (macrolide efflux genetic assembly) found in at least four distinct sites of the pneumococcal genome. The element is transformable and confers macrolide resistance to susceptible S. pneumoniae. The first two open reading frames (ORFs) of the element form an operon composed of mefE and a predicted ATP-binding cassette homologous to msrA. Convergent to this efflux operon are three ORFs with homology to stress response genes of Tn5252. Mega is related to the recently described mefA-containing element Tn1207.1, but lacks genes necessary for transposition and has unique termini and insertion sites. Macrolide resistance due to mega has rapidly increased by clonal expansion of bacteria containing it and horizontally by transformation of previously sensitive bacteria.

A brachytherapy device for the provision of brachytherapy is disclosed. The brachytherapy device has at least one source lumen located outside a movable surface of the device. The source lumen may be secured to the movable outer surface in a manner whereby relative movement of the source lumen relative to the movable outer surface is permitted. The brachytherapy device is inserted into a body cavity. After insertion, the movable surface is moved to position the at least one source lumen closer to the tissue boundary of the cavity. One or more sources of radiation are then placed within the at least one source lumen to provide a customizable treatment. Also disclosed are methods for providing brachytherapy via body cavities.

The present invention is directed to a system for allowing animals to self administer drugs via intranasal absorption. The system comprises an aerosol dispersing apparatus (1) connected to a source of pressurized air (5) for ejecting a pharmaceutical composition contained in a reservoir (8) out of the aerosol dispersing apparatus nozzle head (3) and into a sensing chamber (12) when a sensor (16) detects the presence of an animal in the sensing chamber (12). The system can be used to study the addictiveness of new drugs as well as providing a model system for small animals, such as the mouse, to studying behavioral and physiological responses to addictive drugs.

A computer-implemented method of representing user's navigational path in a web environment includes steps of enabling a user to successively display a plurality of pages of a web site or a web application; maintaining a full breadcrumb path that includes a link to each of the plurality of pages previously displayed to the user; displaying a shortened breadcrumb path on a currently displayed page of the plurality of pages, the shortened breadcrumb path including fewer links than the full breadcrumb path, and displaying the full breadcrumb path only when requested by the user. A computer-implemented method of representing a user's current location within a hierarchical structure of a web site or web application includes steps of maintaining a hierarchical map of the web site or web application; generating a web page that has a predetermined level within the hierarchical map; displaying a hierarchical structure selector on the web page, and when the displayed hierarchical structure selector is selected by a user, displaying an indication of the predetermined level and a link to each hierarchically higher level of the generated web page.

Wearable headlight devices and related methods are provided and can include a luminaire that can include a housing having a luminaire vent therein for receiving cooling air and a light source contained within the housing. An air moving device can be located outside of the luminaire for facilitating cooling air intake through the luminaire vent. An exhaust tube can be connected to the luminaire and the air moving device to facilitate air flow of the cooling air between the luminaire and the air moving device.

摘要:
Methods, systems, and devices are described for determining compliance with a listing of persons banned from conducting financial transactions. Words appearing in a listing of a banned person and a financial transaction may be compared with defined words appearing in a database. Common words appearing in both the listing of the banned person and the database, and the transaction record and the database, may be identified, thereby identifying a first and second set of common defined words. The listing of the banned person is linked with countries based on the first set of common defined words and/or phrases and the transaction record is linked with countries based on the second set of common defined words and/or phrases. The countries may then be compared. Based on the outcome, the financial transaction may be permitted or suspended.
