One of the Best approaches so far for COVID 19 vaccination and antibodies therapy < identifying the receptor-binding domain (RBD) in SARS-CoV-2 S protein and that the RBD protein bound strongly to human and bat angiotensin-converting enzyme 2 (ACE2) receptors. SARS-CoV-2 RBD exhibited significantly higher binding affinity to ACE2 receptor than SARS-CoV RBD and could block the binding and, hence, attachment of SARS-CoV-2 RBD and SARS-CoV RBD to ACE2-expressing cells, thus inhibiting their infection to host cells. SARS-CoV RBD-specific antibodies could cross-react with SARS-CoV-2 RBD protein, and SARS-CoV RBD-induced antisera could cross-neutralize SARS-CoV-2, suggesting the potential to develop SARS-CoV RBD-based vaccines for prevention of SARS-CoV-2 and SARS-CoV infection.

The World’s First Heartless Man

Doctors from the Texas Heart Institute have successfully replaced a patient’s heart with a device that keeps the blood flowing, thereby allowing him to live without a detectable heartbeat or even a pulse.

Here’s how it works:

The turbine-like device, that are simple whirling rotors, developed by the doctors does not beat like a heart, rather provides a ‘continuous flow’ like a garden hose.

Craig Lewis was a 55-year-old, dying from amyloidosis, which causes a build-up of abnormal proteins. The proteins clog the organs so much that they stop working, according to NPR.
*But after the operation, with the ‘machine’ as his heart’s replacement, Lewis’ blood continued to spin and move through his body.

However, when doctors put a stethoscope to his chest, no heartbeat or pulse can be heard (only a ‘humming’ sound)—which “by all criteria that we conventionally use to analyze patients”, Doctor Cohn said, he is dead.

This is proof that “human physiology can be supported without a pulse”.
With all the talk of replacing human organs with those of an animal and electronic hearts, it’s surprising that medical researchers overlooked taking a trip to the plumbing section of the hardware store for replacement parts!

Correct

As a cardiologist, do you agree with this statement?

To My dear colleagues : " Serologic screening studies have reported an increasing incidence of Coeliac disease ( CD ) to the magnitude of two- to fivefold over the past 50 years. This increase is multifactorial: a true rise in disease incidence over time, increasing awareness of CD among clinicians and the general population, and greater utilization of serological tests identifying patients with either atypical presentations or who are asymptomatic. Yet, population studies suggest that the majority of patients with CD remain undiagnosed.... lets be aware of microcytic anemia refractory to iron supplments!!! ,,, intense symptoms of IBS !!! ,,,,, negative serology postive response to glutten free diet!!! ,,, positive serology with no symptoms of CD,,,,, then you will find out that CD is very prevalent and picking up cases in daily practise is not uncommon in egypt..." we see only what we know ,,,,, dont we ???..........
