Nanoparticle Fight Against Cancer

Authors: George Rajna
Comments: 69 Pages.

A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has introduced a novel targeted drug delivery system in the fight against cancer. [41] One day, hospital patients might be able to ingest tiny robots that deliver drugs directly to diseased tissue, thanks to research being carried out at EPFL and ETH Zurich. [40] A team of researchers at the Hebrew University of Jerusalem in Israel has now made such cascades in the lab by encapsulating three enzymes and enzyme cofactors in nanoreactors made from metal-organic framework nanoparticles.

Authors: George Rajna
Comments: 50 Pages.

Salk researchers have mapped the genomes and epigenomes of genetically modified plant lines with the highest resolution ever to reveal exactly what happens at a molecular level when a piece of foreign DNA is inserted. [32] MIT researchers have developed a way to dramatically enhance the sensitivity of nuclear magnetic resonance spectroscopy (NMR), a technique used to study the structure and composition of many kinds of molecules, including proteins linked to Alzheimer's and other diseases. [31] Electronegativity is one of the most well-known models for explaining why chemical reactions occur. [30] Innovations in microscale electronics, medicine, combustion and scores of other technologies depend on understanding and predicting the behavior of electricity on the smallest of length scales.

New Knowledge on Bacteria and Viruses

Authors: George Rajna
Comments: 54 Pages.

University of Otago research to better understand how bacteria and their viruses interact and evolve will enable future studies to exploit the use of bacteria and their viruses for potential biotechnology and health applications. [34] Researchers at Queen's University Belfast have developed a highly innovative new enzyme biomarker test that has the potential to indicate diseases and bacterial contamination saving time, money and possibly lives. [33] Medical physicist Dr. Aswin Hoffmann and his team from the Institute of Radiooncology—OncoRay at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have combined magnetic resonance imaging (MRI) with a proton beam, thus demonstrating for the first time that in principle, this commonly used imaging method can work with particle beam cancer treatments.

High–resolution Mapping of Dna/rna Hypermethylation and Hypomethylation Process in Human Cancer Cells, Tissues and Tumors Under Synchrotron Radiation

Authors: Alireza Heidari, Ricardo Gobato
Comments: 9 Pages. Trends in Res, 2019 doi: 10.15761/TR.1000131 Volume 2(1): 1-2

Changes in DNA/RNA hypermethylation and hypomethylation patterns are an important characteristic of human cancer cells, tissues and tumors. DNA/RNA hypermethylation and hypomethylation is a process by which methyl groups are added to the DNA/RNA molecule. DNA/RNA hypermethylation and hypomethylation was the initial epigenetic abnormality recognized in human cancer cells, tissues and tumors. In addition, DNA/RNA hypermethylation and hypomethylation have brought more heavy metals from human cancer cells, tissues and tumors under synchrotron radiation into the human healthy cells and caused more health in the human cells. Heavy metals are one of the most important environmental pollutants. The aim of present study is to be high–resolution mapping of DNA/RNA hypermethylation and hypomethylation process in human cancer cells, tissues and tumors under synchrotron radiation.

Cinematic View of Fly Brain

Authors: George Rajna
Comments: 52 Pages.

A new fly-through of the fly brain allows anyone to whizz past neurons and visit any of the 40 million synapses where neurons touch neuron. [33] Measuring optical blood flow in the resting human brain to detect spontaneous activity has for the first time been demonstrated by Wright State University imaging researchers, holding out promise for a better way to study people with autism, Alzheimer's and depression. [32] UCLA biologists report they have transferred a memory from one marine snail to another, creating an artificial memory, by injecting RNA from one to another. [31] Scientists at the Wellcome Trust/ Cancer Research UK Gurdon Institute, University of Cambridge, have identified a new type of stem cell in the brain which they say has a high potential for repair following brain injury or disease.

DNA Trace Ancient Ancestry

Authors: George Rajna
Comments: 37 Pages.

Scientists at the University of Sheffield studying ancient DNA have created a tool allowing them to more accurately identify ancient Eurasian populations, which can be used to test an individual's similarity to ancient people who once roamed the earth. [12] In new research, Hao Yan of Arizona State University and his colleagues describe an innovative DNA walker, capable of rapidly traversing a prepared track. [20] Just like any long polymer chain, DNA tends to form knots. Using technology that allows them to stretch DNA molecules and image the behavior of these knots, MIT researchers have discovered, for the first time, the factors that determine whether a knot moves along the strand or "jams" in place.

Ferent Equation of the Human Body

Authors: Adrian Ferent
Comments: 277 Pages. © 2014 Adrian Ferent

Ferent equation of the Human body Ferent equations of the Universe can be applied to any quantum system which contains Matter, Dark Matter and Spiritual Matter. This means Ferent equations of the Universe can be applied to our Milky Way galaxy, to our planet, to human body… Human body The human body is a quantum system composed of Matter, Dark Matter and Spiritual Matter. Spiritual body The aura is the energetic field that surrounds the human body as well as every organism and object in the universe. We see paintings of Christian saints with a circle of white or yellow light around their heads, or angels with their halos; this is the way how people imagined the energetic field of the human body. In Christianity, the apostle Paul introduced the concept of the spiritual body, (1 Corinthians 15:44), describing the resurrection body as ‘spiritual’. The aura is made up of several layers of subtle energy. The Spiritual body is made of Spiritual Matter evolving in time. The most general form of the time-dependent Ferent equation of the Human body. “Ferent equation of the Human body: “ Adrian Ferent Where: |Ψ(r,t)> – is the state vector of the Human body r and t are the position vector and time h – is the Planck constant a – is the Ferent constant s – is the Spiritual constant The Spiritual body is made of Spiritual Matter, composed of S spiritual elementary particles evolving in time. The time-dependent Ferent equation of the Human body, which gives a description of the Human body as quantum system, made of Matter, P elementary particles, Dark Matter, R elementary particles, and Spiritual Matter, S elementary particles, evolving in time. “Ferent equation of the Human body: “ Adrian Ferent Where: Ψ – the wave function of the Human body m1i – the mass of Matter elementary particle i m2j – the mass of Dark Matter elementary particle j m3k – the mass of Spiritual Matter elementary particle k r1P – the position of Matter elementary particle P r2R – the position of Dark Matter elementary particle R r3S – the position of Spiritual Matter elementary particle S The solution to the Ferent equations is the wave function: Ψ. The information about the quantum system is contained in the solution to Ferent equations, the wave function Ψ. The square of the absolute value of the wave function, | Ψ |2 is interpreted as a probability density. Ferent equations are Deterministic, because if I know the wave function at a moment in time I can determine the wave function later in time. The clerics are ignorant in science and the scientists are ignorant in spirituality. That is why science of spirituality is not accepted in universities, in peer-reviewed journals, as Nobel Prize… Scientists from the Pontifical Academy of Sciences were not able to discover a Transdisciplinarity equation or an equation to link Matter with Spiritual Matter. The greatest scientists tried to unify Science and Spirituality and to write a Transdisciplinarity equation without success. It is not easy to understand both Science and Spirituality. My Father helped me to understand Science and my Mother helped me to understand Spirituality. I am the first who discovered a Transdisciplinarity equation; the Ferent equation of the Soul. “Ferent equation of the Soul:” Adrian Ferent 162. I am the first who discovered the Ferent equation of the Human body
