    Abstract: An adapter allows the interconnection of a sensor originating from one manufacturer to be coupled with conventionally incompatible monitors originating from other manufacturers to form a properly functioning pulse oximetry system. The adapter matches a sensor driver in a monitor to the current requirements and light source configuration of a sensor. The adapter also matches a sensor's light detector signal level to the dynamic range requirements of a monitor preamplifier. Further, the adapter provides compatible sensor calibration, sensor type and security information to a monitor. The adapter may have a self-contained power source or it may derive power from the monitor, allowing both passive and active adapter components. The adapter is particular suited as an adapter cable, replacing a conventional patient cable or sensor cable as the interconnection between a sensor to a monitor in a pulse oximetry system.

    Abstract: Described are photochromic organic resin compositions and the impact resistant polymerizates and coating compositions made therefrom. The organic resin composition comprises the reaction product of at least one polyol having greater than 1.0 hydroxyl groups; at least one polyisocyanate having greater than 1.0 isocyanato groups; and at least one polyamine curing agent having greater than 1.0 amino groups. The polymerizates are made photochromic either by the addition of organic photochromic compounds to the reactants used to form the polymerizate or by methods that imbibe or transfer the photochromic compounds into the polymerizate. Optically clear photochromic and impact resistant articles such as ophthalmic lenses and articles having photochromic coatings prepared from the photochromic organic resin compositions are also described.

    Abstract: A keratin hydrogel which can be used as a wound dressing and cell scaffolding. The keratin hydrogel is formed from clean, washed hair by partially oxidizing a significant percentage of disulfide linkages to form cysteic acid groups, while some disulfide linkages remain intact. The partially oxidized hair is treated with a reducing agent, thereby reducing most of the remaining disulfide linkages to cysteine-thioglycollate disulfide and cysteine groups. A soluble fraction of hair is collected and oxidized, such that the reduced sulfur groups are allowed to reform disulfide linkages, thereby binding the keratin together. The cysteic acid groups remain, providing hydrophilic sites within the hydrogel. A higher degree of partial oxidation results in a greater abundance of hydrophilic cysteic acid groups in the hydrogel.

    Abstract: Novel bacterial isolates of B. thuringiensis are disclosed which have enhanced toxicity with respect to previously resistant or insufficiently susceptible insect species, including, but not limited to, Plutella xylostella, Spodoptera frugiperda and Spodoptera exigua, as well as certain secondary pests such as Trichoplusia ni. Such isolates may be characterized by their possession of a particular subset of the genes coding for the various B. thuringiensis &dgr;-endotoxin proteins and by a characteristic plasmid profile, or array, known to be associated therewith. Also disclosed are a method for the efficient identification of such bacterial isolates utilizing generalized or, alternatively, gene-specific DNA probes; cloned or synthesized nucleotide sequences which are useful in the preparation of those probes; compositions containing an insecticidally effective amount of a bacterial isolate of the invention in combination with an acceptable carrier; and a method for the use thereof in the control or eradication of insect pests.
