The timeline of the COVID-19 pandemic lists the articles containing the chronology and epidemiology of SARS-CoV-2, [1] the virus that causes the coronavirus disease 2019 and is responsible for the COVID-19 pandemic. The first human cases of COVID-19 occurred in Wuhan, People's Republic of China, on or about 17 November 2019. [2]
Mitochondrial biogenesis is the process by which cells increase mitochondrial numbers. [ 1 ] [ 2 ] It was first described by John Holloszy in the 1960s, when it was discovered that physical endurance training induced higher mitochondrial content levels, leading to greater glucose uptake by muscles.

SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV. [105] Like the SARS-related coronavirus implicated in the 2003 SARS outbreak, SARS‑CoV‑2 is a member of the subgenus Sarbecovirus (beta-CoV lineage B). [106] [107] Coronaviruses undergo frequent recombination. [108]
Based on the patient's travel history and symptoms, healthcare professionals suspected this new coronavirus. A clinical specimen was collected and sent to CDC overnight, where laboratory testing yesterday confirmed the diagnosis via CDC's Real-time Reverse Transcription-Polymerase Chain Reaction (rRT-PCR) test."
The World Health Organization declared JN.1 a "variant of interest" Tuesday — a designation that applies to variants that are driving new cases and have genetic changes that could help them ...

What are COVID-19 symptoms? Some of the symptoms of COVID-19 include: Fever or chills. Cough. Shortness of breath or difficulty breathing. Fatigue. Muscle or body aches. Headache. Loss of taste or ...
Mitochondrial replication is controlled by nuclear genes and is specifically suited to make as many mitochondria as that particular cell needs at the time. Mitochondrial transcription in humans is initiated from three promoters, H1, H2, and L (heavy strand 1, heavy strand 2, and light strand promoters). The H2 promoter transcribes almost the ...
