  • Patent number: 6747011
    Abstract: Derivatives of apoptolidin, including skeletal homologues, are potent and selective apoptosis-inducing agents which, unlike apoptolidin, do not undergo isomerization under physiological conditions. These compounds exhibit antitumor properties, often superior to those of apoptolidin, and as such can be used in the treatment of cancer and other hyperproliferative disorders.

  • Patent number: 5988569
    Abstract: A holder, mountable on the back of a truck tractor cab, has two electrical plug receptacles and two gladhand keepers. The gladhand keepers are vertically directed and angled with respect to the mounting surface of the cab, so that an operator can store in the keepers the hose-end gladhands associated with the tractor without climbing on, leaning over, or stretching across the frame of the truck behind the cab. The electrical plug receptacles are at an angle away from the surface, making it easier for an operator to insert the plugs into the electrical plug receptacle and thereby reducing wear to the cables.

  • Patent number: 5594750
    Abstract: A MWIR laser is provided having a novel n-type superlattice cladding layer comprising either InAs/AlAs.sub.0.16 Sb.sub.0.84 or In.sub.x Ga.sub.y Al.sub.1-x-y As/AlSb. The n-type superlattice cladding layer may comprise a Si selectively-doped (SD) InAs/AlAs.sub.0.16 Sb.sub.0.84 short-period superlattice (SPS) lattice-matched to an InAs substrate or a Si SD In.sub.x Ga.sub.y Al.sub.1-x-y As/AlSb SPS lattice-matched to a GaSb or InAs substrate. The advantages of the Si SD InAs/AlAs.sub.0.16 Sb.sub.0.84 SPS and Si SD In.sub.x Ga.sub.y Al.sub.1-x-y As/AlSb SPS include: (1) large dynamic range in the electron concentration in the Si-doped n-type cladding layer; and (2) strong hole confinement in the active region. Furthermore, the novel n-type superlattice cladding layer can be deposited without the use of tellurium (Te) which is not a preferred source material for MBE growth of III-V semiconductors.
