In treating HIV infections, the protein is administered alone or in conjunction with conventional AIDS therapies. Also provided are processes for purifying the protein, DNA sequences encoding the protein, and recombinant DNA methods for expressing the protein.

Abstract: New proteins, termed GAP 31, obtainable from the seeds of Gelonium multiflorum, and DAP 30 and DAP 32, obtainable from the leaves or seeds of Dianthus caryophyllus, or the above proteins produced by recombinant means, are useful for treating HIV infections. In treating HIV infections, the protein is administered alone or in conjunction with other anti-HIV therapeutics. Also provided are processes for purifying the proteins, DNA sequences encoding the proteins, hosts expressing the proteins, recombinant DNA methods for expressing the proteins, and antibodies specific for the proteins.

Abstract: A shading device of LCD projecting plate has a pair of shading board being capable of being adjusted to shade the rest projecting areas which are uncovered by the plate and to project the drawing or letters on the optical glass to a wall or a screen clearly whenever used with any projectors.

Abstract: Peptides which exhibit improved broad spectrum antimicrobial activity are designed and synthesized based on the peptide sequences of magainin or PGS peptides. The modified peptide analogues are synthesized by replacing low helical potential amino acid residues with high helical potential residues and modifying the two termini in order to enhance the amphiphilic structures as well as to prolong antimicrobial activity by lowering their susceptibility to protease degradation. For example, low propensity residues within a strategic region of magainin II, e.g. Ser.sup.8, Gly.sup.13 and Gly.sup.18 are modified with Ala which is known to have high propensity. Amidation of Ser.sup.23, and acylation of Gly.sup.1 with acetyl or beta-alanyl and substitution of Gly.sup.1 with beta-alanine are carried out in order to lower the susceptibility to exopeptidase action.

Abstract: A two-stage catalytic hydroconversion process using a large-pore catalyst in the first stage reactor and a small-pore catalyst in the second stage reactor in the two-stage process for hydroconversion of coal or petroleum asphaltene feed materials to produce distillate liquid fuels. The large-pore catalyst is characterized by having pore diameters larger than 1000.ANG. occupying a major portion of the catalyst total pore volume of 0.2 to 1.0 cc/gm, and the small-pore catalyst is characterized by having pore diameters smaller than 1000.ANG. occupying a major portion of the catalyst total pore volume.

Abstract: Disclosed is an improved process for the emulsion polymerization of ethylenically unsaturated monomers in the presence of a polymerization is conducted in the presence of from about 0.02 to about 2.0 percent by weight of the total monomer content, of a hydrophobically modified hydroxyethylcellulose.

Abstract: The compounds of the invention are symmetrical dimers of enkephalin polypeptides comprising enkephalin polypeptide monomers linked at the C-termini thereof with a difunctional amino bridging group. The compounds are useful as investigative tools for probing the opiate receptor membranes, particularly as radiolabelled ligands for exploring the delta opiate receptor, and also have particular use as narcotic and/or analgesic agents.

Abstract: An improved catalyst for a coal liquefaction process; e.g., the H-Coal Process, for converting coal into liquid fuels, and where the conversion is carried out in an ebullated-catalyst-bed reactor wherein the coal contacts catalyst particles and is converted, in addition to liquid fuels, to gas and residual oil which includes preasphaltenes and asphaltenes. The improvement comprises a catalyst selected from the group consisting of the oxides of nickel molybdenum, cobalt molybdenum, cobalt tungsten, and nickel tungsten on a carrier of alumina, silica, or a combination of alumina and silica. The catalyst has a total pore volume of about 0.500 to about 0.900 cc/g and the pore volume comprises micropores, intermediate pores and macropores, the surface of the intermediate pores being sufficiently large to convert the preasphaltenes to asphaltenes and lighter molecules. The conversion of the asphaltenes takes place on the surface of micropores.

Abstract: Structure for foldable baby carriage comprises: a pair of four bar linkages each having a seat tube, a back tube with its lower end connected to the rear end of the said seat tube and its upper end extending upward, an arm rest member with its rear end pivoted to the middle portion of the said seat tube and its front end extending forward, and a front leg extending downward with its upper end pivoted to the front end of the said arm rest and its middle portion pivoted to the middle of the said seat tube; two cross frames, the one with its upper ends pivoted to the front ends of the seat tubes and its lower ends pivoted to the lower ends of front legs, and the other with its lower ends pivoted to the rear ends of the seat tubes and its upper ends to the middle portions of the back tubes; two rear legs extending downward each with its upper end pivoted to the middle portion of the arm rest and its middle portion passing through a sliding sleeve pivoted to the rear end of the said seat tube; and two pairs of twi

Abstract: A carriage, chair, or similar structure is described having two cross frames which are interpivotally connected by means of a two axis pivot joint and which are held in their unfolded position at a fixed angle with respect to each other by rigid brace members pivotally connected to the sides of the frames and characterized in that the said brace members each comprise three sections, the middle sections provide horizontal rests for arms. The carriage, chair, or similar structure also incorporates a two piece toggle bar, and three piece knuckle strut disposed in front to serve both as a support member for the carriage structure and as a rest or support member for the object, e.g., a passenger, to be placed in the structure.

Abstract: A cobalt promoted nickel catalyst supported on refractory material and a process employing said catalyst for the production of hydrogen-containing gases, such as synthesis gas, reducing gas or town's gas, or for the production of methane-enriched gases, such as pipe-line gas.
