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.

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.

So where are we at with this virus people?

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.

Transduction is the process by which foreign DNA is introduced into a cell by a virus or viral vector.

Viral vectors are tools commonly used by molecular biologists to deliver genetic material into cells.

Viruses have evolved?

specialized molecular mechanisms

to efficiently

transport their genomes

inside the cells they infect.

Delivery of genes, or other genetic material, by a vector is termed transduction and the infected cells are described as transduced.

A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another.

Did the paedophiles create the virus?

I think so!

Is Joe Biden the paedophiles choice?

Jury’s out.

Scumbags

Lock them all up and f their vaccine.

Laughter is the best medicine. It can relax muscles. It also gives exercise to body and helps relax joints.

It is possible to laugh on same joke many times but only very pure heart people can do it

Today's world, laughter is very unnatural. It is only to impress others. But real feeling laughter is missing. Only innocent people r able to laugh really.

#LaughterThread

It is not zaruri to create laughter by insulting others.

In early days people used to create laughter by situation. That is always more comedy than just Paxi type insulting laughter.

Laughter like a child helps to cure blood pressure, thyroid n liver issues. It also improve memory

is ADHD a mental illness ?

a thread

ADHD is a neurodevelopmental disorder - people with it are born with it and it cannot be altered because it's part of their brain structure and is seen on brain scans. ADHD is also linked to premature births and hypothyroidism during pregnancy, among other things

from the WHO website: "neurodevelopmental disorders are disabilities in the functioning of the brain that can affect behaviour, memory and/or ability to learn."

neurodevelopmental disorders are not caused by external/environmental factors. you cannot *develop* these conditions

mental illness is a general term for a health problem that significantly affects how someone feels/thinks/behaves. mental illnesses cause suffering to those who experience them, as well as often their loved ones. ADHD does not directly cause suffering.

neurodevelopmental disorders are not mental illnesses. ADHD however, does make it more likely for a person to experience mental illness. ADHD can cause dysfunction and stress, but more often than not this comes from lack of accommodation rather than the symptoms themselves.

While #Tulane school of medicine is rightfully being exposed for its contemporary racism towards faculty, staff, students (and patients) due to the racist firing of Dr. Princess Dennar, it’s important to call out the deeply anti-Black history of this school, specifically... 1/

The way #Tulane became a private institution (originally was a public university) at the end of Reconstruction to avoid having to desegregate. The school charter says it was founded for “white men” only... but there’s more (much more) to this story... 2/

cw: medical racism

Tulane’s school of medicine rose to national prominence for its collection of human “specimens” in their anatomy museum “rivaled only by Harvard”. How did it acquire these “specimens” you might ask?

The collection was “curated” by a Dr. Edward Souchon... 3/

Dr. Souchon was mentored by the late James Marion Sims, the “father of modern gynecology”, who himself had started collecting body parts, organs, and skeletal remains from enslaved Black people during slavery. Souchon continued “curating” his own collection in horrific ways. 4/

The Souchon Collection grew over several decades, eventually touring the state as a traveling “public health” exhibit- nearly all of the body parts stolen, harvested and illicitly acquired from formerly enslaved and poor Black people via Charity Hospital. 5/

Pathways to Public Policy Careers for those interested and looking for global opportunities

Public policy is made when a governing body attempts to address an issue of widespread public concern, such as health care. The process often runs in cycles and can take years.

■After new laws are created, Policy Implementation occurs, often involving federal agencies, state and local governments, bureaucratic entities, and NGOs. Courts get involved as laws and policies are challenged on a variety of fronts.

■Analysis and Evaluation occurs throughout the cycle and involves many players. Policies may be changed — and the cycle begins again.

What is the best advice for someone pursuing a career in public policy?

People often find their way to public policy careers because of an

interest in a particular substantive area. Public policy work can be found in virtually any subject area.

Your ears should perk up when you hear the words “Center for,” “Institute,” “Association,” and “Foundation” because they represent potential employers.

Public policy majors work in the public, private, and nonprofit sectors, such as a government agency or advocacy group.

Continuing education, such as a certification or fellowship, can also advance your career as someone interested in public policy and politics.

THIS IS A CATCHY & ATTENTION-GRABBING TITLE

Today, the Province will likely announce what zone of the reopening framework we'll shift into as of Tuesday. Whatever is announced, though, doesn't change what we need to do. Why?

Kindly read these 14 tweets & we'll tell you. (1/14)

Fun fact: COVID-19 does not follow us on Twitter. COVID doesn't know, or particularly care, if we're in the Red or Orange zone.

The behaviours of the virus do not depend on the current ‘zone’ of public health restrictions. And, to be perfectly candid, neither should ours. (2/14)

Once upon a time we used to say #WeAreInThisTogether in our messaging. Here's the thing: we are, but we aren't. Not everyone is experiencing this pandemic the same.

Nurses, doctors, paramedics & healthcare workers have experienced things much differently than most of us. (3/14)

Some people have been home & isolated for months, while others haven't been able to stop working.

Business owners & hospitality workers have been on a rollercoaster of openings & closures.

Students, parents, teachers & school staff have had to adapt to going from online (4/14)

to in-person learning (and back again) numerous times.
And this virus has disproportionately affected some groups more than others.

But there's the thing: while our experiences of this pandemic haven't been shared, we do have a shared goal.

And we can reach it together. (5/14)
