99 results about "Retinitis" patented technology

Retinitis is inflammation of the retina in the eye, which can permanently damage the retina and lead to blindness. The retina is the part of your eye that is also known as the "sensing tissue." Retinitis may be caused by a number of different infectious agents. Retinitis, also called Retinitis pigmentosa, has a prevalence of one in every 2,500–7,000 people. This condition is one of the leading causes that leads to blindness in patients in the age range of 20–60 years old.

Normal Tissue Toxicity Reducing Microbeam-Broadbeam Radiotherapy, Skin's Radio-Response Immunotherapy and Mutated Molecular Apheresis Combined Cancer Treatments

Normal tissue complications limit curative broadbeam radiotherapy to tumors including lung cancer. Radiation retinitis causing blindness limits quality of life and long term survival for patients with ocular melanoma. This invention pertains to alternative, normal tissue sparing 100 to 1,000 Gy microbeam radiations with least normal tissue complications and concomitant radio-immunotherapy by innate immune response of epidermis and dermis to low dose radiation with 50 kV X-rays. Total body skin radiation with former airport passenger screening machines with 50 kV X-ray is disclosed. Microbeams are generated without contaminating scatter and neutron radiations from collinear gamma ray and electron beam produced by inverse Compton interaction with high energy laser and electron beam and from proton and carbon ion beams in tissue equivalent cylindrical collimators. Extracorporeal immunotherapy and chemotherapy and apheresis of mutated subcellular particles released into circulation in response to cancer-therapies are by clinical continuous flow ultracentrifugation combined chromatography.

Process for generating plasmin in the vitreous of the eye and inducing separation of the posterior hyaloid from the retina

A process for inhibiting vascular proliferation separately introduces components into the eye to generate plasmin in the eye in amounts to induce complete posterior vitreous detachment where the vitreoretinal interface is devoid of cortical vitreous remnants. The process administers a combination of lysine-plasminogen, at least one recombinant plasminogen activator selected from the group consisting of urokinase, streptokinase, tissue plasminogen activator, chondroitinase, pro-urokinase, retavase, metaloproteinase, and thermolysin and a gaseous adjuvant to form a cavity in the vitreous. The composition is introduced into the vitreous in an amount effective to induce crosslinking of the vitreous and to induce substantially complete posterior vitreous detachment from the retina without causing inflammation of the retina. The gaseous adjuvant material is introduced into the vitreous simultaneously with or after the lysine-plasminogen and recombinant plasminogen activator such as recombinant urokinase to compress the vitreous against the retina while the composition induces the complete posterior vitreous detachment.

Use of crispr/cas9 as in vivo gene therapy to generate targeted genomic disruptions in genes bearing dominant mutations for retinitis pigmentosa

Described herein are methods and compositions for genomic editing. Clustered regularly interspaced short palindromic (CRISPR) allows for highly selective targeting and alteration of genetic loci. Here, the Inventors demonstrate CRISPR as capable of being used in living animals to prophylactically prevent a genetic disease from manifesting. Targeting and disruption of mutated rhodopsin gene prevents progression of retinitis pigmentosa in the retinal cells of a transgenic rat model. Such techniques allow for treatment methods in subjects with dominant genetic mutations, often associated with lack of a gene product, or a toxic gene product. The described technology effectively abrogates deleterious effects due to the presence of a mutated gene copy allowing the normal function of the wild-type protein to prevent cell and vision loss. The efficacy of these in vivo mechanisms are widely extensible to similar dominant negative gene mutations causing disease, or other types of genetic disease.

Oral delivery of angiotensin converting enzyme 2 (ACE2) or angiotensin-(1-7) bioencapsulated in plant cells attenuates pulmonary hypertension, cardiac dysfunction and development of autoimmune and experimental induced ocular disorders

Emerging evidence indicates that diminished activity of the vasoprotective axis of the renin-angiotensin system, constituting angiotensin converting enzyme2 (ACE2) and its enzymatic product, angiotensin-(1-7) [Ang-(1-7)] contribute to pulmonary hypertension (PH). However, clinical success for long-term delivery of ACE2 or Ang-(1-7) would require stability and ease of administration to increase patient compliance. Chloroplast expression of therapeutic proteins enables their bioencapsulation within plant cells to protect from acids and gastric enzymes; fusion to a transmucosal carrier facilitates effective systemic absorption. Oral feeding of rats with bioencapsulated ACE2 or Ang-(1-7) attenuated monocrotaline (MCT)-induced increase in right ventricular systolic pressure, decreased pulmonary vessel wall thickness and improved right heart function in both prevention and reversal protocols. Furthermore, combination of ACE2 and Ang-(1-7) augmented the beneficial effects against cardio-pulmonary pathophysiology induced by MCT administration.Experiments have also been performed which indicate that this approach is also suitable for the treatment or inhibition of experimental uveitis and autoimmune uveoretinitis These studies provide proof-of-concept for a novel low-cost oral ACE2 or Ang-(1-7) delivery system using transplastomic technology for pulmonary and ocular disease therapeutics.
