Fox Foundation Backs Inflazome Parkinson’S Project

Par
March 26, 2019



Irish start-up Inflazome has won $1 million in funding from the Michael J. Fox Foundation (MJFF) to help it develop a brain imaging probe for Parkinson's, as well as a new drug class for the disease.
The cash injection will be used to support a positron emission tomography (PET) imaging technique that will help Inflazome bring forward small molecule drugs that target NLRP3, a protein complex or 'inflammasome' thought to be involved in harmful inflammatory processes in Parkinson's and other neurodegenerative diseases.
Specifically, the money will be used to fund the development of a PET tracer that will be able to identify the presence of NLRP3 inflammasomes, which are part of the innate immune system and a defence against pathogens.
In some diseases, including Parkinson's, it is thought that the inflammasome starts to function incorrectly and becomes activated even when there is no pathogen to fight, leading to the destruction of neurons in the brain.
The hope is that giving drugs that block NLRP3 activation in the brain can prevent the loss of brain cells and, in turn, stop the loss of motor function that is the main symptom in Parkinson's. There are no medications on the market that prevent brain cell loss in Parkinson's patients, with current therapies focusing on managing symptoms.
Inflazome says the non-invasive PET tracer will be able to image inflammasome-driven inflammation in the brain and show whether its NLRP3-targeted drugs are binding to the inflammasomes as intended.
The PET tracer will also be used to select patients for inclusion in clinical trials "at the appropriate staging" of Parkinson's disease, says the biotech, and that should increase the chance of showing a positive result if the drugs are effective. It will also help Inflazome to determine what doses are needed for patients in larger clinical trials in the future.
Inflazome's founders – Matt Cooper of the University of Queensland in Brisbane and immunologist Luke O'Neill of Trinity College Dublin – have shown in previous studies that an NLRP3 inhibitor called MCC950 given orally once a day halted the development of Parkinson's in several animal models of the disease. That work was also funded by the MJFF.
MCC950 was originally a Pfizer drug tested for rheumatoid arthritis, but never advanced beyond phase 1 b development, according to a recent Nature article.
The biotech completed a €40 million (around $46m) second-round financing to take its NLRP3 inflammasome drugs into clinical trials to treat diseases characterised by chronic, low-level inflammation.

HTML5 Games On Android

Par
On my last hollidays, I made two HTML5 games, and published on android market. Nowadays javascript has powerful libraries for doing almost everything, and also there are several compilers from java or c code to javascript, converting opengl c code to html5 canvas, but definitely, javascript execution is slower than dalvik applications, and of course much slower than arm c libs. For improving the speed of sounds and images loader, I have used javascript asynchronous execution and scheduling priority has been controlled with setTimeout/setInterval which deprioritize or priorize a code block. This games are published on the android market here: Android Planets and here: Far Planet Related news Hacker Hardware Tools Pentest Tools Port Scanner Hacker Tools For Mac Tools Used For Hacking Hacker Techniques Tools And Incident Handling Easy Hack Tools Hacking Tools Kit Hacking Tools Usb Hacker Hardware Tools Hacker Tools Hardware Hack Tools For Windows Hacking Tools For G...

Abdominal pain after a motor vehicle accident

Par
CASE A 22-year-old man was brought to the ED complaining of abdominal pain after a rollover motor vehicle accident. He was the front seat passenger and was wearing a seat belt. Although he was trapped in the vehicle and it caught on fire, he did not suffer any cutaneous burns. History  The patient's past medical history was significant for attention-deficit hyperactivity disorder. He admitted to using tobacco and alcohol socially, but denied illicit drug use. He denied any medication use or drug allergies. A review of systems was positive for complaints of abdominal pain and anxiety. Physical examination  The patient's vital signs were: BP, 112/51 mm Hg; heart rate, 110 beats/minute; respirations, 23; SpO 2 , 95% on room air; and temperature, 37.4° C (99.3° F). On ED arrival, he was awake, alert, and oriented but appeared anxious and agitated. His pupils were equal, round, and reactive to light. His head was normocephalic with a 2-cm laceration on the left ear. The pati...
