NDI Foundation posted this:Strain of bacteriorhodopsin-BRBacteriorhodopsin (BR) is the newest biotechnological product that will make a revolution in many spheres of life: from medicine to defense. Data on the production of the BR in the world is hidden. From open sources - the only seller (and, possibly, producer) is an American company SIGMA, selling BR for research. We offer developed strain of BR. A method of producing allows to get BR in large quantities to several kg. The strain is certified and stored in special depositories. BR has unique qualities - the main one is - memory. For BR, it was necessary to find a special strain - producer of BR. Just several countries has the strain (USA, Russia, ..), other data hidden. We also developed such an unique strain.
RAMOT at Tel Aviv University Ltd. posted this:A novel behavioral bioassay for preclinical testing and characterization of CNS agentsOur team, including zoologists, statisticians, and computer scientists have developed a new hi-res bioassay for preclinical testing and characterization of CNS agents, extracting key animal-centered parameters of behavior via computerized tracking and measurement of free exploration. The features that distinguish our system and method from other existing systems and methods are: elaborate data preparation for analysis and a methodology that secures replicability of results across laboratories, and exposes active management of kinematic variables. Our measured parameters are carefully designed, animal-centered building blocks of behavior. They are selected on the basis of an in-depth understanding of the mouse’s functional world. These quite unexpected and unusual parameters reflect the animal’s cognitive and emotional state and its information processing capacity; therefore they are most prone to be affected by drugs that act on respective CNS structures that mediate these states. Unlike all other existing systems we expose and quantify the rich and highly organized developmental dynamics of self regulated behavioral growth. The dynamics of this process before and after genetic manipulation and/or pharmacological treatment can now be readily measured by our system, articulating the effects of potential CNS drugs on behavioral growth and decay processes.

RAMOT at Tel Aviv University Ltd. posted this:Oral Mucosa-derived Stem Cells: A Unique Population for the Prevention and Treatment of Ischemic Heart FailureStem cells (SC) are considered crucial building blocks for any regenerative strategy. Adult oral mucosa (OM) is a unique source for generating adult pluripotent stem cell (OPSC) populations. This uniqueness consists in the fact that 95% of the OM whole populations in culture (1st – 8th passages) express markers of embryonic and mesenchymal SC. Thus, in contradistinction to known sources which comprise very low numbers of SC, OPSC generation for clinical use is simple and cost effective and does not require cumbersome cost-consuming purification steps. The general objective is to lay the foundation for the development of a variety of products based on the pluripotency and simple and cost effective generation of billions of OPSC. The major aim of the proposed project is to develop a product for the treatment of ischemic heart failure (IHF). This product which will serve as a proof of concept was selected based on medicals needs, market cap and time to market. The specific aims of the proposal are: 1. To develop a cardiac product aimed at treating ischemic heart failure (IHF). The aim is to test the safety and therapeutic effect of OPSC on experimental IHF in a minipig model. 2. To strengthen the intellectual property by fully characterizing the profile of OPSC. The prevalence of IHF continuously increases (1 million new cases every year in the western world) and currently the market cap is estimated in the range of billions. Project ID : 10-2011-260

There are no available treatments to specifically reduce the risk of CAA. In this research we aim to assess brain tissue damage and cognitive impairment resulting from CAA in animal model and to investigate a novel approach to immune therapy. Methods: We have shown that nasal vaccination with a proteosome adjuvant (Protollin) that is well tolerated in humans, decreases amyloid plaques in an Alzheimer’s disease mouse model. It was recently reported that an overexpression of TGF-?1 under the control of an astrocyte promoter GFAP in mice results in CAA. TGF-?1 mice were nasally treated with Protollin on a weekly basis starting at the age of 13 months for three months. Following treatment animals were subjected for MRI and cognition analysis. Results: Here we show that nasal Protollin activates perivascular macrophage and potently decreases vascular amyloid in TGF-?1 mice. Using MRI we found that while PBS treated animals showed a significant enlargement of the lateral ventricles area, Protollin prevents further brain damage and prevents pathological changes in the blood-brain barrier. Vascular risk factors have been found to be associated with vascular dementia. Using an object recognition test and Y-maze, we found significant improvement in cognition with the Protollin treated group. Interpretation :Our study demonstrates that activation of macrophages by Protollin is a novel approach to reduce microhemorrhage, prevent stroke and improve cognition in a model of cerebral amyloid angiopathy.

Fundació URV posted this:A robust breast cancer computer-aided diagnosis systemWe analyze breast cancer in mammographies, ultrasonographies, magnetic resonance imaging (MRI) and thermographies. Our analysis includes mass/normal breast tissue classification, benign/malignant tumor classification in mammograms and ultrasound images, tumor detection in thermograms, mammogram registration and analysis of the evolution of breast tumors. We also quantify and visualize the evolution of breast tumors in patients undergoing medical treatment. While the previous works mainly focus on analyzing one type of breast images, we implement a robust CAD system for detecting, classifying and studying the evolution of breast cancer. This CAD system analyzes breast cancer in several types of medical images. To implement our CAD system, we use computer vision, pattern recognition and machine learning methods. We also need to collect a large scale breast cancer dataset from hospitals. This dataset should include mammograms, ultrasound, thermograms and MRI images for the same patients. Our CAD gives accurate diagnosis results because it gathers information from different sources.

RAMOT at Tel Aviv University Ltd. posted this:Novel Anti Bacterial DrugTwo non-toxic short peptides were conjugated to form a novel drug candidate. One of the peptides is a polymyxin-B or polymyxin-E analog (PMBN or PMEN, respectively) while the other is an immune cell chemotactic peptide (fMLF). The resultant new drug candidates (PMBN-fMLF or PMEN-fMLF) exhibit three antimicrobial activities: (a) it binds specifically to gram negative bacteria, thus enhancing penetration of antibiotics into the bacteria and (b) it promotes bacterial killing by blood phagocytes and (c) It binds to free LPS in the blood thus reduces effect on patients.

RAMOT at Tel Aviv University Ltd. posted this:GSK-3 Peptide Inhibitors for the Treatment of CNS Related DisordersNovel Glycogen synthase kinase 3 (GSK-3) inhibitors were developed. These inhibitors are substrate competitors that interact specifically with the GSK-3 substrate binding site. GSK-3, like other protein kinases, has a common structurally conserved catalytic domain that comprises the ATP-binding loop. The great majority of reported inhibitors developed to date are ATP-competitive compounds; however, such inhibitors demonstrate limited specificity, as the ATP-binding pocket is highly conserved among protein kinases. In contrast, the substrate binding site is more specific, and thus targeting inhibitors toward this domain yields more specific compounds. The strategy is based on exploiting the unique recognition motif of GSK-3 which comprises a phosphorylated residue and using molecular and computational analyses. Project ID : 10-2011-132

RAMOT at Tel Aviv University Ltd. posted this:Targeted filamentous bacteriophages as therapeutic agentsTargeted drug-carrying filamentous bacteriophages have been developed as a novel therapeutic approach for the treatment of infectious disease and cancer. The phages are genetically-modified to display an antibody or a targeting peptide as a targeting moiety on their surface and are used to deliver a cytotoxic drug to the target. The drug is linked to the phages by means of chemical conjugation through a labile linker subject to controlled release. In the conjugated state the cytotoxic drug is devoid of cytotoxic activity and is activated following its dissociation from the targeting phage at the target site in a temporally and spatially controlled manner.
