Abstract: A high temperature-resistant fire extinguishing robot, comprising: a high temperature-resistant robot chassis system and a high temperature-resistant turret system. The high temperature-resistant robot chassis system carries the high temperature-resistant turret system to perform movements and obstacle avoidance, provides the high temperature-resistant turret system with energy, and further comprises: a high temperature-resistant tract drive system, a thermal protection system, and a control and sensor system, the high temperature-resistant track drive system being arranged outside of the thermal protection system, and the control and sensor system being arranged within the thermal protection system.

Abstract: A high temperature-resistant wheel, comprising: an elastic hub assembly (1), which has a thermal insulation layer integrated therewith so as to insulate the elastic hub assembly (1) from exterior high temperatures; and a rigid wheel barbed ring (2), which has the elastic hub assembly (1) fastened inside and rotates together with the elastic hub assembly (1). A robot, which comprises the high temperature-resistant wheel.

Abstract: A method is described to identify secreted proteins identified with stages of malignancy of cancer. The proteins are initially identified by trapping them with a fluorescent protein containing vector that can insert in any gene. The secreted proteins are initially identified by their fluorescence. Secreted proteins identifying tumors with specific degrees of malignancy are isolated to determine if they can serve as markers of cancer progression.

Abstract: Immunocompromised rodents that have been modified to express a fluorescent protein in substantially all tissues are described. These rodents are useful as models for gene expression, tumor progression and angiogenesis. Also provided are model systems where heterologous tissues fluorescing in a first color are transplanted into hosts that have been modified to fluoresce in substantially all tissues with a second color.

Abstract: A method to follow the progress of tumor treatment in subjects utilizes bacteria that have been modified to express a fluorescent protein. The method can also monitor expression of genes associated with the bacteria that produce therapeutic agents during the course of treatment, optionally against a background of fluorescence generated by the tumor itself. The method permits visualization of the progress of treatment in live subjects so that treatments can be modified according to their efficacy.

Abstract: Methods of obtaining faithful expression libraries from tissue samples comprise extraction of RNA from intact tissue cultured in three-dimensional sponge-gel based histocultures.

Abstract: Infection by P. carinii can be treated by administering methioninase optionally in combination with additional therapeutic agents, such as antibiotics.

Abstract: A method to determine a total cysteine in biological fluids utilizes similarly treated portions of the fluid with a homocysteinase and a non-specific desulfurase.

Abstract: Methods for inhibiting the growth of tumor cells by combination treatment with a selenium-containing prodrug and an enzyme for which it is a substrate are described. The treatment also enhances the effect of anti-tumor agents.

Abstract: Living cells can be stably modified to emit different colors from the cytoplasm and nucleus, thus permitting analysis of the status of said cells and the effect of agents on said cells either by visual or instrumentally-aided observation. These observations may be made, if desired, in real time. In addition, rates of proliferation and drug sensitivities can be determined in vitro in real time by the use of cells modified to express a single fluorescent protein and observing fluorescence intensity as a function of time.

Abstract: Imaged animal models for coronavirus infection are described.

Abstract: Methods of recovering desired living cells contained in a tissue sample are based on separation based on fluorescence of a fluorescent protein produced by the desired cells.
