Regarding adaptive immunity to SARS-CoV-2, both T cells, and B cell producing neutralizing antibodies (nAbs) contribute some degree of clinical protection. The important role of neutralizing antibodies in protection of SARS-CoV-2 has been demonstrated by the results of passive transfer of nAbs to non-RBD epitopes on the spike (S) protein that was able to prevent severe SARS-CoV-2 infection in animal models. Regeneron has reported similar data in humans (passive vaccination). Convalescent plasma transformation has also shown an ability to dramatically improve clinical symptoms. Pizer/BioNTech (BNT162b2), is a lipid nanoparticle formulated nucleoside-modified mRNA that encodes the viral spike glycoprotein of SARS-CoV-2.

The non motor symptoms include constipation and REM sleep disorder (1,2) . Age is the biggest risk factor, and usually older adults are affected, It is a multifactorial disease with many environmental factors such as head injury well water consumption, and pesticide exposure and genetic mutations. The most important genes will be discussed in the following sections Sun, 07 Aug 2022 00:00:00 GMT http://dr.limu.edu.ly/handle/123456789/3994 2022-08-07T00:00:00Z http://dr.limu.edu.ly/handle/123456789/3986 Heart failure patient and anemia Idris, Basma Anemia: reduction of the total circulation red cell mass below normal limits Heart failure: heart is unable to pump blood at a rate sufficient to meet the metabolic demands Of the tissue Sun, 07 Aug 2022 00:00:00 GMT http://dr.limu.edu.ly/handle/123456789/3986 2022-08-07T00:00:00Z
