摘要:
The present invention provides novel MDCK-derived adherent non-tumorigenic cell lines that can be grown in the presence or absence of serum. The cell lines of the present invention are useful for the production of vaccine material (e.g., viruses). More specifically, the cell lines of the present invention are useful for the production of influenza viruses in general and ca/ts influenza viruses in particular. The invention further provides methods and media formulations for the adaptation and cultivation of MDCK cells such that they remain non-tumorigenic. Additionally, the present invention provides methods for the production of vaccine material (e.g., influenza virus) in the novel cell lines of the invention.

An equilateral foot bed and a system using the equilateral foot bed are provided for treating foot injuries and deformities, while allowing the patient to remain ambulatory. Embodiments include a foot bed having a first portion and a second portion, the second portion having a greater thickness than the first portion. The portions of differing thickness support, align and cushion portions of the foot. The foot bed is selectively usable in either a left foot-receiving or a right foot-receiving configuration.

An endotracheal intubation device having a curvable portion and internal optics or a viewing device which facilitate the insertion of an endotracheal tube into a patient. The curvable portion comprises a portion of the tubular element having one or more sets of slits to provide flexibility. The curvable portion curves in a controlled manner from a fully straight configuration.

The present invention relates to novel MDCK cells which can be to grow viruses, e.g., influenza viruses, in cell culture to higher titer than previously possible. The MDCK cells can be adapted to serum-free culture medium. The present invention further relates to cell culture compositions comprising the MDCK cells and cultivation methods for growing the MDCK cells. The present invention further relates to methods for producing influenza viruses in cell culture using the MDCK cells of the invention.

A gaming system for playing a restricted-access progressive game comprises a database containing data, including a list of players having access to the restricted-access progressive game. The system includes a gaming terminal with a connection port for coupling the gaming terminal to the data-base. The gaming terminal has a player-identification device providing player information. The information is compared with data in the database to determine whether the restricted-access progressive game can be activated and game information displayed at the gaming terminal. A method of operating the progressive game comprises receiving a player-identification input at the gaming terminal and transmitting a player-identifier signal from the gaming terminal to a remotely located controller that determines accessibility to the progressive game. The method further includes receiving, at the gaming terminal, a progressive game accessibility signal from the remotely located controller and, if the signal is positive, allowing a player to conduct the progressive game.

The present invention is directed to a harvester of influenza virus from fertilized chicken eggs in a continuous manner comprising a control panel, a connector having three openings, a pipette, a peristaltic pump, and a sample reservoir. In another embodiment, the harvester comprises a pipette gun having a retrieving button and an aspiration button instead of the control panel. The present invention is also directed to a method of harvesting the influenza virus using the pipette gun.

A mobile that is constructed from modular components. The mobile is particularly suited for displaying pictures (i.e. photographs) and updating pictures from time to time. The modular components include display envelopes, a modular support, a hanger, and a suspension medium (i.e. thread). Each of the display envelopes are capable of simultaneously displaying two pictures. The display envelopes are suspended from the modular support via the suspension medium. The hanger is centrally located along the length of the modular support and facilitates hanging the modular support and the associated display envelopes from an external structure. The modular support and interconnected display envelopes are optimally balanced by the alignment of the hanger. In particular, the modular support and the associated display envelopes are balanced by longitudinally sliding the hanger along the modular support.

In a preferred embodiment, a pair of tap shoes each having toe and heel taps, associated with each tap there being an audio-pickup transducer mounted one adjacent each tap, connected by signal-carrying wiring to a common electronic radio-wave transmitter and power-source mechanism that receives and sends the signal received from the respective transducers to a radio-wave receiver and amplifying and speaker mechanism spaced-away from the tap shoes such that tapping sounds of the taps on a hard surface are received, amplified and broadcast through speakers.
摘要:
A picture frame includes four legs delineating a rectangular opening and coupling members joining the adjacent ends of the legs, each leg including a longitudinal outer web, a high front flange and a low rear flange projecting upwardly from the web front and rear edges and coplanar legs projecting toward each other from the flanges to form confronting channels and each coupling member includes a corner angle section with arms terminating at their ends in mutually perpendicular faces and rectangular tongues offset from the edges of and projecting from the ends faces into sliding engagement with the channels of adjacent frame legs, the front and peripheral faces of the end sections being coplanar with the leg front flange front faces.
摘要:
A picture frame has a lip for supporting the front of a picture and at least one groove. Resilient means, such as spring clips, have tongues for insertion into the groove. The clips support the rear of the picture and can hold pictures of varying thickness. A second groove can be disposed behind said first groove for holding extra thick pictures, such as canvasses.
