We Might Be Treating Schizophrenia All Wrong

Quote
A new study run by researchers in Japan and published earlier this year in Cell Reports Medicine suggests that for at least a significant portion of patients, the immune system is mistakenly attacking a protein in the brain—which may be the real mechanism giving rise to schizophrenic symptoms in the first place.

Scientists create synthetic mouse embryos, a potential key to healing humans
 
 
Quote
Stem cell researchers in Israel have created synthetic mouse embryos without using a sperm or egg, then grown them in an artificial womb for eight days, a development that opens a window into a fascinating, potentially fraught realm of science that could one day be used to create replacement organs for humans.The objective, scientists involved with the research said, is not to create mice or babies outside the womb, but to jump-start the understanding of how organs develop in embryos and to use that knowledge to develop new ways to heal people.

‘Miracle’ herpes treatment eradicates tumours in terminally-ill cancer patients  
 
Quote

 
  Terminally-ill cancer patients have seen their tumours completely eradicated or shrunk after being treated with a genetically-engineered version of the herpes virus.
Scientists at the Institute for Cancer Research in London have developed a new therapy which infects and destroys cancer cells while also rallying the immune system.
In early trials to assess the safety of the therapy, one quarter of patients with end-of-life cancer saw their tumours stop growing, shrink or disappear completely.
Krzysztof Wojkowski, 39, a builder from West London who had no treatment options left after developing a salivary gland tumour, has been cancer-free for two years since taking part in the trial at the Royal Marsden in London in 2020.
“I was told there were no options left for me and I was receiving end of life care,” he said. 
 
 
   “I had injections every two weeks for five weeks which completely eradicated my cancer.
“I’ve been cancer-free for two years now, it’s a true miracle, there is no other word to describe it. I’ve been able to work as a builder again and spend time with my family, there’s nothing I can’t do.”
    Virus causes cancer cells to burst The genetically engineered virus - called RP2 - is injected directly into the tumour where it multiplies, causing cancer cells to burst from within.
It also blocks a protein called CTLA-4 which dials down the immune system, and so gives the body more of a chance to fight off the cancer. In addition, the virus also produces molecules which spark the immune system into action against cancer.
The therapy was tested on 39 patients with cancers including skin, oesophageal and head and neck cancer who had exhausted all other treatments.
Results showed that around one quarter saw a benefit.
The herpes simplex virus is a common infection, which many people already carry latently without problems.
Researchers looked at patient biopsies before and after RP2 injections and found positive changes in the tumour’s “immune microenvironment” – the area immediately around the tumour. Injections led to more immune cells in the area, including CD8+ T-cells, and “switched on” genes linked to the “anti-cancer” immune response.
The team found that most side effects of RP2 were mild – some of the most common were fever, chills, and fatigue. None of the side effects were serious enough to require medical intervention.
Professor Kristian Helin, chief executive of The Institute of Cancer Research, London, said: “Viruses are one of humanity’s oldest enemies, as we have all seen over the pandemic. But our new research suggests we can exploit some of the features that make them challenging adversaries to infect and kill cancer cells.
“It’s a small study but the initial findings are promising. I very much hope that as this research expands we see patients continue to benefit.”
 Potential to become new treatment option Study leader Kevin Harrington, professor of biological cancer therapies at The Institute of Cancer Research, said: “Our study shows that a genetically engineered, cancer-killing virus can deliver a one-two punch against tumours – directly destroying cancer cells from within while also calling in the immune system against them.
“It is rare to see such good response rates in early-stage clinical trials, as their primary aim is to test treatment safety and they involve patients with very advanced cancers for whom current treatments have stopped working.
“Our initial trial findings suggest that a genetically engineered form of the herpes virus could potentially become a new treatment option for some patients with advanced cancers – including those who haven’t responded to other forms of immunotherapy.
“I am keen to see if we continue to see benefits as we treat increased numbers of patients.”
The research was presented at the 2022 European Society for Medical Oncology Congress (ESMO), and the team are hoping to move to bigger trials.

Anti-ageing scientists extend lifespan of oldest living lab rat
 
Quote

Scientists working on an experimental anti-ageing therapy claim to have broken a record by extending the lifespan of a lab rat called Sima.
Named after the Hindi word for “limit” or “boundary”, Sima is the last remaining survivor from a group of rodents that received infusions of blood plasma taken from young animals to see if the treatment prolonged their lives.Sima, who was born on 28 February 2019, has lived for 47 months, surpassing the 45.5 months believed to be the oldest age recorded in scientific literature for a female Sprague-Dawley rat, the researchers say. So far, Sima has outlived her closest rival in the study by nearly six months.

Ja imam problem sa aritmijama, naišao sam da bi kreatin trebalo da izbegavam, nije da sam planirao da ga uzimam svakako :)

Sa druge strane, poručio taurin i l-arginin jer mogu da pomognu kod aritmija, a onda vidim da ih i badibilderi cene, zbog drugih stvari naravno, nije baš rasprostranjeno u prodaji al vidim da ga nude ove radnje što nude suplemente za u teretanu.

Duža konzumacija kanabisa i promene u epigenomu:

In conclusion, we observed significant associations between recent and cumulative marijuana use with DNA methylation markers across time. We also observed cis-meQTLs and DMRs associated with marijuana use and biologically relevant pathways and diseases, suggesting potential shared genes between marijuana use and cellular proliferation, hormone signaling, and mental disorders. Additional studies are needed to replicate and verify the observed associations presented here. With the greater number of states legalizing marijuana for medical and recreational use, as well as the expected rise in its use, examining the association between marijuana and the epigenome may aid in elucidating the molecular and biological processes influencing downstream health conditions and may serve as potential biomarkers to identify recent and long-term marijuana use and intervene in the early stages of their related health outcomes.

An Aging Expert Thinks Humans Can Live for 20,000 Years. He's Not Crazy.

Naravno, sve je ovo teorija, jelte, na dugačkom štapu ali me jeste ponukalo da razmišljam, kada bismo zaista pristup terapiji koja popravlja svu štetu na DNK i zaustavlja starenje ćelija, kako bismo onda tretirali gubitak života u saobraćajnoj nesreći ili ubistvo? Verovatno bi nam stil života bio DRASTIČNO promenjen već i time što bismo na smrt gledali kao na izuzetak a ne pravilo.

Ha! Kruciforma je mnogo dramatilniji koncept, ona te oživljava kad umreš, dok ovo o čemu ovaj čovek priča opravlja ćelije i DNK tako de NE UMREŠ!!!!!!!!!!
