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.

If you shine light of high enough energy on to a metal, electrons will be emitted from the metal.

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].

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.

All Women are at risk of getting Cervical Cancer. It often affect women over age 30.

Long-lasting infection with certain types of human papillomavirus (HPV) are the main cause of cervical cancer.

HPV is a virus that is passed from one person to another during sex.

A Thread 🚺

More than half of sexually active people might have HPV at some point in their lives, but few women will get CERVICAL CANCER.

Early Screening tests & the HPV vaccine can help prevent cervical cancer.

When cervical cancer is diagnosed early, it is highly treatable &....

associated with long survival and good quality of life.

Most (almost all) cervical cancers are caused by HPV.

There are many types of HPV.
Some HPV types can cause changes on a woman’s CERVIX that can lead to cervical cancer as time goes on, WHILE other types can cause genital

or skin WARTS . HPV is so common that most people get it at some time in their lives.

HPV usually causes no symptoms so you can’t tell that you have it. For most women, HPV might be SELF LIMITING (ie it will go away on its own); However, if it doesn't, there are a chances that

over time it may result to cervical cancer.

OTHER FACTORS CAN INCREASE YOUR RISK of CERVICAL CANCER —
•Having HIV/AIDS
•Smoking.
•Using Oral contraceptives (birth control pills) for a long time (5+ years)
•Having birth to many children (4+ yrs).
•Having many sexual partners

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.

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

1/23 We haven't had a lot to celebrate during this pandemic. But achieving the milestone of offering vaccine to the over 70s, health and care workers and the most clinically vulnerable just before target date is a huge cause for celebration, given the scale of the achievement.

2/23 When Margaret Keenan got her first jab in Coventry on December 8th last year, who’d have thought that, by Valentine’s Day, we’d have vaccinated over fourteen million people across the UK in just ten short weeks? Amazing, extraordinary and truly, really, world class!

3/23 I’ve been struck by how much joy and relief has been brought to those doing the vaccinations and those receiving them. A GP told me yesterday that nothing had given him greater pleasure in his long career. And that the patient's relief was sometimes overwhelming.

4/23 It's vital to recognise the extraordinary contribution of the staff and volunteers who have made this happen. One of my close family had their jab yesterday and was in awe of the volunteer standing outside in the freezing cold for a four hour shift meeting and greeting.

5/23 What I wanted to share in this thread was the slightly untold story of some of the extraordinary challenges the NHS has had to overcome to deliver this target. Requiring superhuman effort from NHS leaders and staff, way beyond the call of duty. Five challenges set out below.
