Title: Thermosetting plastics from a natural resin
Inventor: ANASTASIOU DIMITRIOS EFTHYMIOU
IPC: C09F1/00
Filed: 2017-12-18
Abstract: The current invention describes the production process of full green (100% environmental friendly) thermosetting polymers by using the natural resin Chios Mastic as the main raw material (or the mastic produced in regions other than Chios or by using mastic colophony (mastic rosin)). This process consists of the fractionation of the mastic in the proper solvent, its epoxidation and its self-polymerization or its co-polymerization with hardeners. The product can be used as a metal adhesive or for other uses like the common uses of synthetic resins. Both the self- polymerization product and the whole production method are totally environmental friendly, since all the raw materials are either natural and renewable or can be fully recovered.

Inventor: OVED KFIR
IPC: G01N33/569
Filed: 2013-02-08
Abstract: Antibiotics (Abx) are the world s most misused drugs. Antibiotics misuse occurs when the drug is administered in case of a non bacterial infection (such as a viral infection) for which it is ineffective. Overall it is estimated that 40 70% of the worldwide Abx courses are mis prescribed. The financial and health consequences of Abx over prescription include the direct cost of the drugs as well as the indirect costs of their side effects which are estimated at >$15 billion annually. Furthermore over prescription directly causes the emergence of Abx resistant strains of bacteria which are recognized as one of the major threats to public health today. This generates an immediate need for reliable diagnostics to assist physicians in correct Abx prescription especially at the point of care (POC) where most Abx are prescribed. Accordingly some aspects of the present invention provide methods using biomarkers for rapidly detecting the source of infection and administrating the appropriate treatment.
