Known modulators of PKA activity include factors that either activate or inhibit AC (Adenylate Cyclase), resulting in an increase or decrease in cAMP (Cyclic Adenosine 3',5'-monophosphate) levels. The enzyme occurs naturally as a four-membered structure with two regulatory (R) and two catalytic (C) subunits.KA, once activated can phosphorylate several other substrates. The ADR-Alpha/Beta stimulation of cAMP-PKA phosphorylates several proteins related to excitation-contraction coupling like activation of RyR (Ryanodine Receptor), Pln (Phospholamban), CRP (C-Reactive Protein) but inhibits TnnI (Troponin-I).
If you feel like you canât get out of bed, donât. Serious fatigue, along with chills and body aches, are signs that you have the flu. So you need plenty of rest. Acetaminophen, naproxen, or ibuprofen can help with body aches.
Most people with the flu recover on their own without medical care. People with mild cases of the flu should stay home and avoid contact with others, except to get medical care. If you get the flu, your health care provider may prescribe medicine to help your body fight the infection and lessen symptoms. The main way to keep from getting the flu is to get a yearly flu vaccine. Good hygiene, including hand washing, can also help.
