During a normal pregnancy, oxidative stress enhances antioxidant mechanisms that are capable of reacting by way of enzyme activity and non-enzyme free radical deactivators. However, pregnancy is also a state in which this adaptation and balance may be easily disrupted.

In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighbouring particles of a continuous material exert on each other, while strain is the measure of the deformation of the material.

For example, when a solid vertical bar is supporting an overhead weight, each particle in the bar pushes on the particles immediately below it. When a liquid is in a closed container under pressure, each particle gets pushed against by all the surrounding particles.

The container walls and the pressure-inducing surface (such as a piston) push against them in (Newtonian) reaction.

These macroscopic forces are actually the net result of a very large number of intermolecular forces and collisions between the particles in those molecules. Stress is frequently represented by a lowercase Greek letter sigma (σ).

Residual stresses inside a plastic protractor are revealed by the polarized light.

2020 marks the start of the quantum dot revolution.

Completely ignoring the fact that "photocatalytic generation of reactive oxygen species (ROS) from quantum dots (QDs) has been widely reported."

Results: It was found that whereas singlet oxygen (1O2) was not produced by photoexcited QDs, superoxide anion(O2− )and hydroxyl radicals(OH) were generated by QDs, especially in the presence of a physiological concentration of electron donating agent including NADH.

Using cell metabolic activity assays and various probes of ROS generation, the formation of ROS in cellular environments was demonstrated.

Conclusion: Illumination of QD-treated cells and bacteria with light did affect viability. The above results, together with those of assays in the presence of various scavengers of specific ROS, indicate that the formation of ROS by QDs mainly proceeded via electron transfer.

Did the paedophiles create the virus?

I think so!

Is Joe Biden the paedophiles choice?

Jury’s out.

Lock them all up and f their vaccine.

This nonspecific cation channel opens when illuminated with blue light, depolarizing the cell [4, 6] to trigger action potentials cells with high temporal precision [5]. Since the initial discovery of ChR2, many modifications have been made to refine the kinetic properties.

For example, ChETA, engineered to address limitations of spike fidelity with ChR2, has faster temporal kinetics and can maintain reliable spike precision up to 200 Hz [7].

Halorhodopsins (NpHR), light-gated chloride pumps activated by yellow light, allow for temporally specific hyperpolarization with single spike precision [8–10].

Archaerhodopsin-3 (Arch), a yellow light-activated outward proton pump, is an increasingly popular tool for light-induced hyperpolarization to inhibit cellular activity. Arch recovers spontaneously from inactivation with a much shorter recovery time than NpHRs [11].

Arch currents continue to increase with increasing light intensity, while NpHRs saturate [11]. The increased light sensitivity of the ArchT variant, along with better membrane targeting, allows for improved neural silencing both at cell bodies and terminals [12].

A staple of anti-lockdown conspiracism in yoga/wellness is that public health measures are oppressive, authoritarian, and stifling what it means to be human. Masks suppress identity and speech. Vaccines assault the sovereign body. Influencers must rise up against tyranny! /1

Ironically, pandemic management in economies where yoga/wellness is lucrative has been a neoliberal, choose-your-own-adventure mess in which centre-right governments barter with public health to enact a patchwork of half-measures that punish the poor and marginalized. /2

The goal is not universal health rights, or protecting medical systems, or saving as many lives as possible. The goal is to return to business-as-usual, using public health as a pit stop on a productivity race off a cliff. The ice caps aren’t melting fast enough, I guess. /3

Right-leaning governments, like influencers, have assessed the COVID threat with the magical bias of limitless optimism. Then they work to normalize COVID casualties as a new cost of doing business. *This* is what alt-healthers and Qamoms call “socialist”, or “communist”. /4

Centre-right governments and wellness influencers share a goal: get back to the optimism of making productivity heroic and consumption virtuous, without any reflection on structural issues of injustice, or what universal health care funding and standards would look like. /5

UAMS has taken the extraordinary step of asking leadership across our health system to refrain from traveling over the coming holidays and report to work or be available if needed. Other hospitals in our state are considering similar measures.

Although the health care system in the state of Arkansas is stressed right now, it is holding up, and additional surge capacity exists. But that capacity is not infinite.  Every day, we become more and more concerned about our ability to manage what lies ahead.

As health professionals, we are doing all we can. However, one thing is certain. We can’t meet this challenge unless you are with us. As Secretary Jose Romero of the AR Dept. of Health has said, we are in the midst of a “surge within a surge” in this COVID-19 pandemic.
