Abstract: A method of producing a transgenic monocotyledonous plant includes culturing a thin section explant from a monocotyledonous plant, such as sugarcane, wheat or sorghum, in the presence of an auxin and, optionally, a cytokinin, prior to transformation. Optimally, the thin section is oriented during this pre-transformation culture period of 1-6 days so that a basal surface is substantially not in contact with the culture medium. The cultured explant is then transformed followed by a rest period of 4-15 days in a culture medium without selection agent but comprising an auxin and, optionally, a cytokinin. After this rest period, transgenic plants are selectively propagated from the transformed plant tissue in the presence of a selection agent such as paromomycin sulphate or geneticin. This system provides rapid, efficient generation of transgenic monocotyledonous plants from transformed, non-callus tissue and thereby reduces the likelihood of somaclonal variation among transgenic progeny.

Abstract: A method of plant micopropagation is provided whereby a thin section of non-callus tissue obtained from a monocotyledonous plant, such as sugarcane, wheat or sorghum, is cultured in the presence of a cytokinin and/or an auxin. Optimal regeneration occurs when a basal surface of the thin section is oriented so as to be substantially not in contact with the culture medium. This micropropagation method produces mature monocotyledonous plants by either organogenic or embryogenic regeneration without substantial callus formation. By avoiding use of callus as a starting tissue, this method reduces the likelihood of propagated plants displaying somaclonal variation.

Abstract: A PCR-based method for the identification of species of the genus Eimeria, (commonly known as coccidia), is described. The method is genus-specific and utilizes either, or both, of two novel primer sets; designated WW1 (SEQ ID NO:31) and WW3r (SEQ ID NO:32), and, WW2 (SEQ ID NO:33) and WW4r (SEQ ID NO:34).

Abstract: An apparatus for supplying an enteral or parenteral fluid to a patient is a cooperative assembly of a rotary peristaltic pump and a fluid delivery set. The peristaltic pump has (a) a housing and (b) a peristaltic rotor projecting from the housing on a rotatable drive shaft. The housing has first and second receptacles for retaining and supporting the fluid delivery set. The fluid delivery set has (a) a drip chamber, or sight chamber, (b) a plurality of lengths or segments of flexible tubing, and (c) fluid connection elements therefor. The fluid delivery set defines a fluid pathway from a supply container of the enteral or parenteral fluid to a connector element adapted to be connected to a device for introducing the fluid into the patient. Preferably the fluid delivery set has a tension responsive pinch valve to prevent bolus feeding in the event that the fluid delivery set becomes displaced from the pump housing.

Abstract: A fluid delivery set has three lengths of flexible tubing. The first length of flexible tubing at one end is connectable to or integral with a supply container for enteral or parenteral fluid, and at the other end is connected to the inlet of a drip chamber. The second length of flexible tubing is connected at one end to the outlet of the drip chamber, and at the other end to the inlet of a retention/connector device that has about a 90.degree. bend therein. The third length of flexible tubing is connected at one end to outlet of the retention/connector device, and at the other end is connectable to or integral with a means for introducing an enteral or parenteral fluid into the body of a patient. Preferably, a tension responsive pinch valve is operatively associated with the second length of flexible tubing.

Abstract: Delay circuitry is used in a circuit to delay the transmission of groups of data until another circuit expects these groups of data. In one embodiment, emulating circuitry is used to emulate the timing of transmitter and receiver UART FIFOs. This emulating circuitry uses delays equal to the amount of time the UART FIFOs take to serially shift out data in the transmitter UART FIFO, and to serially shift in data in the receiver UART FIFO. This allows the modem chip to use a parallel-to-parallel FIFO buffer for the transmitter FIFO buffer and the receiver FIFO buffer.

Abstract: A mask value generator is used to produce a mask value for deencrypting encrypted instructions from a memory. This encryption mask generator can produce a encryption mask value from a seed value and a program counter value. The seed value can stored in a memory outside the core microprocessor. The encryption mask value can be used to deencrypt instructions in an "exclusive or" logic section.
