Fused tetanus is when there is no relaxation of the muscle fibers between stimuli and it occurs during a high rate of stimulation. [5] A fused tetanic contraction is the strongest single-unit twitch in contraction. [6] When tetanized, the contracting tension in the muscle remains constant in a steady state. This is the maximal possible ...
Summation, which includes both spatial summation and temporal summation, is the process that determines whether or not an action potential will be generated by the combined effects of excitatory and inhibitory signals, both from multiple simultaneous inputs (spatial summation), and from repeated inputs (temporal summation).
The EMA also initiated an assessment for all COVID‑19 vaccines used in the EU for immune thrombocytopenia (ITP), described as low blood platelet levels that could lead to bruising and bleeding, as a possible side effect, whilst also stating that up to this point no link with any COVID‑19 had been established.

Several studies found only weak signs of adaptive evolution early in the COVID-19 pandemic. [c] Kang et al. wrote that SARS-CoV-2 had exhibited relatively little genetic variation by 2021. [47] Tai et al. wrote that population expansion rather than positive selection explained the mutation frequency spectrum during the early pandemic. [49]
Kimberly Walton, a spokesperson for the Texas Health Resources system, declined to answer questions about Salinas’ case, but said that doctors order drug tests if there is a concern about ...
An estimated one-third of developers surveyed in 2020 by the GDC stated that COVID-19 caused a delay of the games they were working on, a combination of the pandemic and the remote working conditions. [134] By 2021, this had increased to 44% by 2021 in a subsequent GDC survey. [135] Some games that were delayed included:
