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
RAMOT at Tel Aviv University Ltd. posted this:Immunotherapy for Stroke and Cognition in a Cerebral Amyloid Angiopathy Animal ModelCerebral amyloid angiopathy (CAA) is due to amyloid accumulation in the vessel walls leading to hemorrhagic stroke, and cognitive impairment. 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.

UNIVERSIDAD DE ALICANTE posted this:Novel and simple procedure for dispersing graphene derivatives in chemically curable resins.The Laboratory of Adhesion and Adhesives of the University of Alicante and the company Dental Global Training, have developed a new procedure to incorporate efficiently graphene derivatives (nanofibers, nanosheets, nanoparticles) in chemically cured resins by using an in situ polymerization technique. The method is very simple and fast, it provides an excellent dispersion of the graphene derivatives in both the solid components of the resin and in the cured polymer matrix, and is entirely friendly with the environment. The novel method does not require the use of organic solvents nor water, ultrasounds, and high pressure/temperature. The resulting resin composites show excellent mechanical properties, good wear resistance, easy manipulation and increase the insolubility in oral fluids, and therefor they have special interest in applications in odontology, traumatology and non-medical applications too (automobile, construction, civil engineering, aeronautics, space engineering, electronics and optics). It is looking for companies interested in acquiring this technology for its commercial exploitation.

RAMOT at Tel Aviv University Ltd. posted this:Harnessing inhibitory RNA based- nanoparticles for therapeutic intervention in blood cancersModulating T cells functions by down regulating specific genes using RNA interference (RNAi) holds tremendous potential in advancing targeted therapies in many immune related disorders including cancer, inflammation, autoimmunity and viral infections. Hematopoietic cells, in general, and primary T lymphocytes, in particular, are notoriously hard to transfect with small interfering RNAs (siRNAs). Herein, we describe a novel strategy to specifically deliver siRNAs to murine CD4+ T cells using targeted lipid nanoparticles (tLNPs). To increase the efficacy of siRNA delivery, these tLNPs have been formulated with several lipids designed to improve the stability and efficacy of siRNA delivery. The tLNPs were surface functionalized with anti-CD4 monoclonal antibody (mAb) to permit delivery of the siRNAs specifically to CD4+ T lymphocytes. Ex vivo, tLNPs demonstrated specificity by targeting only primary CD4+ T lymphocytes and no other cell types. Systemic intravenous administration of these particles led to efficient binding and uptake into CD4+ T lymphocytes in several anatomical sites including the spleen, inguinal lymph nodes, blood and the bone marrow. Silencing by tLNPs occur in a subset of circulating and resting CD4+ T lymphocytes. Interestingly, we show that tLNPs internalization and not endosome escape is a fundamental event that takes place as early as one hour after systemic administration that determine tLNPs efficacy. Taken together, these results suggest that tLNPs may open new avenues for the manipulation of T cell functionality and may help to establish RNAi as a therapeutic modality in leukocyte-associated diseases.

Fundació URV posted this:NEW PROCEDURE FOR OBTAINING MONOLAYERS OF FUNCTIONALIZED NANOPARTICLESThis new procedure (not described in the bibliography) allows the manufacture of monolayers of metal nanoparticles linked by molecules of organic compounds. As you can see in Specifications, this procedure consists in two successive processes. One of the main advantages of this technology is the minimization of impurities in the functionalized monolayer compared to commonly used techniques. Besides, the manufacture of Schotty diode with this new procedure has been shown for the first time. In the same line, this procedure allows the use of monolayers of metal nanoparticles for metabolite detection. These are two unique and differents aspects of this technology in relation to other known used techniques.
