Abstract: A method and system for efficient direct DMA for processing connection state information or other expediting data packets. One example is the use of a network interface controller to buffer TCP type data packets that may contain connection state information. The connection state information is extracted from a received packet. The connection state information is stored in a special DMA descriptor that is stored in a ring buffer area of a buffer memory that is accessible by a host processor when an interrupt signal is received. The packet is then discarded. The host processor accesses the ring buffer memory only to retrieve the stored connection state information from the DMA descriptor without having to access a packet buffer area in the memory.

Abstract: A method, computer readable medium, and a system for communicating with networked clients and servers through a network device includes establishing a plurality of direct memory access (DMA) channels across a host system bus over which a plurality of executing applications each having a respective application driver communicate with a network through a network device configured to receive and transmit network data packets. At a first port in the network device, a first network data packet destined for an executing application is received. A first DMA channel over which to transmit the first network data packet towards the destined executing application is identified, and the first network data packet is transmitted to the destination executing application over the designated DMA channel mapping to the first port.

Abstract: A method for the enumeration of micronucleated erythrocyte populations while distinguishing platelet and platelet-associated aggregates involves the use of a first fluorescent labeled antibody having binding specificity for a surface marker for reticulocytes, a second fluorescent labeled antibody having binding specificity for a surface marker for platelets, and a nucleic acid staining dye that stains DNA (micronuclei) in erythrocyte populations. Because the fluorescent emission spectra of the first and second fluorescent labeled antibodies do not substantially overlap with one another or with the emission spectra of the nucleic acid staining dye, upon excitation of the labels and dye it is possible to detect the fluorescent emission and light scatter produced by the erythrocyte populations and platelets, and count the number of cells from one or more erythrocyte populations in said sample.

Abstract: The present invention relates a method for assessing in vivo hematotoxicity. The method utilizes differential staining of nucleated and non-nucleated blood cells, and also differential labeling of cells with functional versus dysfunctional mitochondrial membrane potential. Quantitative analyses can be conducted on stained whole blood specimens, and is based on blood cells' fluorescent emission and light scatter properties following exposure to an excitatory light source. The ratio of certain cell populations can be readily measured. Furthermore, it is also possible to express cell population values in terms of number per unit volume. This invention can be used to evaluate the hematotoxicity of drugs, chemicals, radiation, and other exogenous agents, or the effects that a suspected protective agent may have on induced hematotoxicity. Furthermore, the matrix of measurements provided by this invention is useful in estimating radiation dose, i.e., retrospectively.

Abstract: The present invention relates a method for the enumeration of in vivo gene mutation. The method utilizes differential staining of GPI-anchor deficient erythrocyte populations to distinguish between wild-type and pig-a gene mutants. Quantitative analyses can be conducted on erythrocytes and/or reticulocytes, and is based upon fluorescent emission and light scatter following exposure to an excitatory light source. Counting of mutant erythrocytes or reticulocytes relative to the number of total erythrocytes or reticulocytes can be used to assess the DNA-damaging potential of an exogenous chemical agent, the DNA-damaging potential of an exogenous physical agent, the effects of an exogenous agent which can modify endogenously-induced DNA damage, and the effects of an exogenous agent which can modify exogenously-induced DNA damage. Kits for practicing the invention are also disclosed.
