Of the many viruses screened, adenovirus 36 has been found to be a strong candidate virus that is associated with obesity, based on evidence in various model systems as well as clinical data. The mechanism of how the adenovirus could lead to obesity is not known and this paper proposes some new insights into how oxidative stress could be a possible mechanism of how adenovirus might lead to obesity. This paper reviews the relevant literature of both the effect of adenovirus on cells' anti-oxidant response and the link between obesity and oxidative stress.

"Our results suggest that oxidative stress may be partly responsible for the toxicity of adenovirus transduction."

"Concordantly, E1A sensitized cells to the cytotoxic effects of oxidative stress and enhanced the accumulation of reactive oxygen species in response to pro-oxidant challenge. These results demonstrate that expression of E1A impedes the cellular response to oxidative stress, including the induction of ferritin."

Research in Alzheimer disease has recently demonstrated compelling evidence on the importance of oxidative processes in its pathogenesis. Cellular changes show that oxidative stress is an event that precedes the appearance of the hallmark pathologies of the disease, neurofibrillary tangles, and senile plaques.

A viral infection that involves virus invasion, protein synthesis, and virion assembly is typically accompanied by sharp fluctuations in the intracellular levels of metabolites. Under certain conditions, dramatic metabolic shifts can result in various types of cell death. Here, we review different types of adenovirus-induced cell death associated with changes in metabolic profiles of the infected cells.

As evidenced by experimental data, in most cases changes in the metabolome precede cell death rather than represent its consequence. In our previous study, the induction of autophagic cell death was observed following adenovirus-mediated lactate production, acetyl-CoA accumulation, and ATP release, while apoptosis was demonstrated to be modulated by alterations in acetate and asparagine metabolism.

On the other hand, adenovirus-induced ROS production and ATP depletion were demonstrated to play a significant role in the process of necrotic cell death. Interestingly, the accumulation of ceramide compounds was found to contribute to the induction of all the three types of cell death mentioned above. Eventually, the characterization of metabolite analysis could help in uncovering the molecular mechanism of adenovirus-mediated cell death induction and contribute to the development of efficacious oncolytic adenoviral vectors.

Oxidative stress is involved in the pathogenesis of many diseases. Overexpression of antioxidant enzymes by gene therapy may protect tissues from oxidative damage. Because the reactive oxygen species hydrogen peroxide can diffuse across cell membranes, we hypothesized that overexpression of the antioxidant catalase within certain cells might protect neighboring cells.

To test this hypothesis, we transduced retinal pigment epithelial (RPE) cells in vitro and in vivo with adenovirus carrying the catalase gene (Ad.CMV.catalase). After transduction of only a subset of RPE cells in vitro, all cells in the culture were protected from exogenous hydrogen peroxide. Similarly, in vivo, eyes injected with Ad.CMV.catalase had high catalase levels in the RPE, which protected the adjacent

photoreceptors from light damage and reduced photoreceptor oxidative stress

as measured by the markers 4-hydroxynonenal and nitrotyrosine.

Opsins are a group of proteins made light- sensitive via the chromophore retinal (or a variant) found in photoreceptor cells of the retina.

Quantum effect

While in the retina, the nanoparticles are stimulated by visible light entering the eye – and if a quantum dot is stimulated while it is in close proximity to a neural cell, it triggers an action potential in that cell which is interpreted as vision by the brain.

Photosynthesis is a well-established source of reactive oxygen species (ROS) in plants. The photosynthetic electron transport chain (PET) operates in an aerobic environment; thus, regulatory systems are required to minimize ROS production.

Scientists have found that a virus can stimulate photosynthesis in bacterial hosts. The work, which was performed at the University of Kaiserslautern and Ruhr University Bochum was reported in the Journal of Biological Chemistry.

"a virus can stimulate photosynthesis in bacterial hosts."

Some bacteria are able to use a process called photosynthesis to convert energy from sunlight into another form of energy they can use to grow. Within the bacteria, structures known as photosystems are responsible for absorbing light and transferring the energy to other molecules.

God bless you all. 🙏🏻

"To be very specific, NPs either boost up the photosynthesis processes by improving LHC (Light Harvesting Complex) in plants or hinder their pathways by blocking ETC (Electron Transport Chain) and they affect photosynthetic rate by change in several genes and enzymes like Carbonic anhydrase, RUBISCO and PEP caboxylase."

Lanthanide-doped upconversion nanoparticles (UCNPs) are capable of converting near-infra-red excitation into visible and ultraviolet emission. Their unique optical properties have advanced a broad range of applications, such as fluorescent microscopy, deep-tissue bioimaging, nanomedicine, optogenetics, security labelling and volumetric display.

However, the constraint of concentration quenching on upconversion luminescence has hampered the nanoscience community to develop bright UCNPs with a large number of dopants. This review surveys recent advances in developing highly doped UCNPs, highlights the strategies that bypass the concentration quenching effect, and discusses new optical properties as well as emerging applications enabled by these nanoparticles.

Upconversion nanoparticles (UCNPs) are a unique class of optical nanomaterials doped with lanthanide ions featuring a wealth of electronic transitions within the 4f electron shells. These nanoparticles can up-convert two or more lower-energy photons into one high-energy photon1,2,3.

Lambda switching (sometimes called photonic switching, or wavelength switching) is the technology used in optical networking to switch individual wavelengths of light onto separate paths for specific routing of information.

In the 1980s, Nobel laureate Francis Crick suggested that light might have the right stuff for controlling neurons of different types, thanks to its ability to provide timed pulses with millisecond temporal precision. However, light penetrates only a few hundred microns into the surface of the brain, scattering without affecting signaling. The challenge became: How can we get the brain to respond to light? This question gave rise to the field of optogenetics, and the emerging idea of replacing electrical stimulation with a combination of optics and genetic modification.

In just over a decade, the discovery of numerous opsins with different specializations has allowed scientists and engineers to make rapid progress in mapping brain activity.

In the early 2000s, researchers Edward Boyden and Karl Deisseroth at Stanford University, USA, approached the problem by attempting to genetically encode brain cells with photosensitive properties. In 2004, they successfully confirmed that the opsin called channelrhodopsin, a microbial photosensitive protein derived from algae, could be transduced into neurons to control their electrical signaling, turning them on by opening neuronal ion channels in response to pulses of blue light.

@themac - I love the level of research that you have put into this thread. I would love to know what prompted you to include all these specific sources. I think I missed part of the thread. I am a biologist and am curious about your theories.

@themac I haven't researched as you have but based on my experiences teaching biology and biotechnology, I have chosen not to take this experimental vaccine. Have I been vaccinated before, of course, but the use of RNA in a vaccine troubles me. If we consider the mechanisms of gene regulation in cells, RNA molecules act in so many ways to alter gene expression. Most viruses have RNA as their genome and have developed so many tricks to incorporate their genetic material into the host's genome or take over the host's cellular machinery to replicate the viral particles. Whole families of ncRNAs or miRNAs exist that can silence gene expression through RNA interference or other regulatory actions. I look forward to reading more closely the references that you supplied. Molecular genetics and manipulation techniques are expanding rapidly in our current age. I want to discuss the nanoparticles more with you when I get caught up to speed.

Just found out that one of the ingredients of the vaccine listed on the package insert is the hormone HCG. If you don't know, HCG is the naturally occurring hormone produced by a WOMAN'S body when she becomes pregnant which makes it so a woman can't get pregnant again once she becomes pregnant; it stops ovulation until she gives birth and CAN continue being produced as long as she's breastfeeding.
We *know* that pregnant women who choose to take this NON-Vaccine are miscarrying in record numbers!
This hormone is also why the original release of the info on this TOXIN that there was a SEVENTY PERCENT RATE of STERILIZATION!
That's the ONLY REASON that this substance would be placed into this mRNA-carrying substance!
We *know* that injecting hormones into the ELDERLY human body can have devastating consequences!
The deaths from this poisonous cocktail are being grossly under-reported and misrepresented!
Gates' and the Cabal's ultimate goal is DEPOPULATION!

Loved this reply. 🙏🏻

The third trimester is the least accurate time to date a pregnancy. Estimates based on an ultrasound can be off by as much as three weeks, so doctors rarely adjust dates during the third trimester.

Conclusion: This study shows a significant correlation between hCG and fetal sex at third trimester of gestation only, possibly caused by a gender factor and a shift in synthesis and/or in metabolism of hCG from the second to the third trimester.
