  • Publication number: 20240092879
    Abstract: The present invention relates to a new composition of human recombinant antibody fragments in both single chain or Fab format, which is capable of completely neutralizing the venom of the scorpion Centruroides sculpturatus Ewing (C. sculpturatus. In particular the new composition comprises the scFv fragment 10FG2 (SEQ. ID. No: 1), which has broad cross-reactivity against various Mexican scorpion venom toxins, and the scFv fragment LR (SEQ. ID. No: 2), with more limited cross-reactivity. Alternatively, the new composition comprises the Fab 10FG2 fragment (SEQ. ID. No: 3 and SEQ.ID. No:4) and the Fab LR fragment (SEQ. ID. No: 5 and SEQ.ID. No 6). The two antibody fragments recognize independent epitopes, present in the two main toxins of the scorpion C. sculpturatus, so that they do not interfere with each other during their binding to the same, on the contrary the antibody fragments of the present invention complement the neutralizing activity.

  • Publication number: 20180282758
    Abstract: The present invention provides a method to obtain DNA constructs that encode 3-domain Cry toxins (also called Cry toxins, Bt toxins, or ?-endotoxins) lacking helix ?-1. These DNA constructs have been modified to encode proteins that kill insects that are resistant to the corresponding unmodified Cry toxins. The DNA constructs encoding the Modified 3-Domain Cry Toxins and the encoded Modified 3-Domain Cry Toxins are provided together with the molecular vectors and the host cell comprising said constructs and the recombinant methods to produce the Modified 3-Domain Cry Toxins. Additionally, compositions comprising the Modified 3-Domain Cry Toxins are disclosed. The resistance of the insects to unmodified Cry toxins is due to reduced toxin binding to the insects' midgut receptors. The invention further provides methods to overcome resistance in crop pests.

  • Patent number: 9927012
    Abstract: An improvement of a worm gear speed reducer is provided where the output gear is substituted by a threaded chain comprised of nut-like threaded bodies mounted on the extended rods of two parallel endless chains, thus the contact surfaces of the drive screw and the threaded chain are much greater than the contact surfaces of the worm gear reducer, and thus the load capacity and wear resistance are much higher. The screw applies the driving force at the centroid of the contact surface of the threaded chain. There are three embodiments which may be a roller screw, a ball screw or a plain translation screw. With the roller screw or the ball screw there is rolling contact and thus the efficiency of the present invention is higher than that of the worm gear reducer which permits it to be used as an amplifier.

  • Patent number: 9707159
    Abstract: Three adhesives formulated with Trimethylolpropane Trimethacrylate (TMPTMA) that do not contain BisGMA were developed, whereby the mutagenic and teratogenic risk by the release of bisphenol A is eliminated, and presented a better performance compared to the three commercial adhesives prepared with BisGMA (Adhesive A, Adhesive C and Adhesive B). The invention provides an adhesive used in one-step and provides a system which is formed by a primer and a slurry. The adhesives of the invention were compared with two commercial controls. They were physically characterized by assessing: hardening time, adhesion stress, elastic modulus, sorption and solubility at different pHs (6.8 and 7.7); by the obtained values premature detachments, white lesions below the appliance and microfiltration are avoided; its fluidity, film thickness were evaluated and were compared with those obtained from the three commercial adhesives. Storage stability and thermogravimetric analysis were assessed.
