A recording device that is coupled to a book. The recording device records, saves and plays back a plurality of discrete messages. An archival control disables and enables the device, thus permitting the user to ensure that no new messages will be accidentally recorded over existing saved messages.

Hydrocarbon stapling of apolipoprotein mimetic peptides increases the helicity of the peptides, enhances their ability to promote cholesterol efflux by multiple mechanisms and makes them resistant to proteolysis. Hydrocarbon stapled amphipathic helical peptides are useful in the treatment of cardiovascular diseases and other disorders.

A method for producing a polycarbonate article having improved ultraviolet protection, the method comprising extruding a substrate comprising polycarbonate; impregnating an ultraviolet radiation absorber into a surface of the substrate to form an interlayer; and laminating a weatherable film onto the interlayer of the substrate. This method allows a weatherable acrylic film to be uniformly applied to the substrate to provide long term anti-yellowing performance. Articles made by this dual-layer process have excellent weathering performance for extended periods of time and can be employed in the production of commercial signs.

A compact, smooth surfaced, flexible and formable, elongate apparatus that has a hair-clog snagging end portion for insertion into drains for snagging and removing the common hair clogs that exist in the upper portion of drains typically around the drain pop-up mechanism and drain trap. The elongate shaft (10) may be bent along it's complete length into any shape and remain fixed in that shape to accommodate compact storage as well as forming a grasping and twisting handle for the shaft while it is in the drain or bending the hair-snagging end of the shaft for easier insertion and navigation within the drain. The hair-clog snagging portion, which is at the distal end of the shaft, is in the form of a pad (12), which maximizes the surface area of hair hooking members (38). The hair-snagging pad consists of the hook portion of hook and loop fasteners and contains a multitude of miniature, hook formed, polymeric elements which aggressively entangle hair-clogs for quick retrieval from the drain without dismantling the drain and without using dangerous chemicals in the drain.

The methods of the present invention allow for the measurement of ribonucleotide reductase (RR) activity, an important enzyme in the de novo DNA synthesis pathway. Ribonucleotide reductase converts all four ribonucleotides to their deoxy form and is a rate-controlling step in this pathway. Biosynthetic pathways of deoxyribonucleotides (dN) have received considerable attention in the context of anti-proliferative chemotherapy. Inhibitors of various steps in dN biosynthesis, including inhibitors of RR are among the most useful chemotherapeutic agents in cancer, viral infections, and other therapeutic uses. DNA synthesis from the dN salvage pathway is also an important component to DNA replication. The relative contributions from RR vs. salvage pathways are critical to the actions and effectiveness of chemotherapeutic agents that act on nucleoside metabolic pathways. Until now, however, it has not been possible to study these metabolic processes in vivo. Disclosed within are methods of measuring RR activity in vivo and in vitro which find use, among other things, in drug discovery, development, and approval.
摘要:
Cooking appliances, cooking assemblies, and cooking assembly components that improve heat distribution are provided. In one embodiment, a cooking assembly has a sear grid including a radiant panel having an undulating shape. The panel defines at least one generally parabolic dome with a radiused peak to allow liquids at the peak to be rapidly heated by the burner. The dome has sides extending away from the peak with a generally increasing slope to cause liquids flowing down the sides of the dome to accelerate. In another embodiment, a double U-shaped burner is provided. A U-shaped burner has a base for positioning at the front of the cooking assembly and a pair of legs that extend toward the rear of the cooking assembly. A second U-shaped connecting tube is positioned to connect the U-shaped burner base to the front of the cooking assembly housing.
