Answer:
Thin and Thick filament.
Explanation:
The actin and myosin are the important proteins of the muscles. These proteins shows striations of the skeletal and cardiac muscle, when observed under the microscope.
Actin protein is the major constituent of the thin filament. Thin filament is 7 nm in diameter and made of globular proteins. Myosin protein is the major constituent of the thin filament. This filament is 15 nm in diameter.
Thus, the actin comprise of thick filament and myosin comprise of thin filament.
Hydrogen bonds rely on polar and covalent bonds because the hydrogen will have a very slight positive proton charge because of the negative electrons being pulled more towards the other element. Because of this proton positive charge, the hydrogen will be attracted to other electronegative charges. This is information on a polar covalent bond. This explains why this is really reliable for hydrogen's usage.
Background- In patients with intracranial artery stenosis, a long-term advantage of dual antiplatelet therapy (DAPT) over single antiplatelet therapy (SAPT) for the prevention of recurrent stroke has not been proven. We studied patients with intracranial arterial stenosis who were enrolled in the Cilostazol Stroke Prevention Study for Antiplatelet Combination trial, a randomized controlled trial in high-risk Japanese patients with ischemic stroke, to compare the efficacy and safety of DAPT with cilostazol and clopidogrel or aspirin to those of SAPT with clopidogrel or aspirin. Techniques and Outcomes In patients with ischemic stroke with symptomatic or asymptomatic intracranial arterial stenosis of at least 50% in a major intracranial artery, we compared the vascular and hemorrhagic events between DAPT and SAPT.
Patients were divided into two groups: 275 were given DAPT, while 272 were given SAPT. In contrast to SAPT, which had a higher risk of serious or life-threatening bleeding, DAPT had a lower risk of ischemic stroke (hazard ratio [HR], 0.47; 95% CI, 0.23-0.95); and a composite of stroke, myocardial infarction, and vascular mortality (HR, 0.48; 95% CI, 0.26-0.91). Conclusions In patients with intracranial artery stenosis following stroke, DAPT using cilostazol was superior than SAPT using clopidogrel or aspirin for the prevention of recurrent stroke and vascular events without raising bleeding risk.
<h3>What is
stroke?</h3>
When anything prevents blood flow to a portion of the brain or when a blood artery in the brain bursts, a stroke, also known as a brain attack, happens. The brain either ages or suffers harm in both scenarios. A stroke may result in permanent brain damage, chronic disability, or even fatality.
