Tick-borne encephalitis (TBE) is a viral infectious disease that is transmitted by a bite from an infected tick and can progress to death. (who.int)

Approximately 1% of all cases of acute arthritis are thought to have a viral etiology. (medscape.com)

Rider says that when DRACO detects a cell with double-stranded RNA, it activates a so-called cellular 'suicide switch,' in much the same way that human cells are programmed to self-destruct if they begin to grow out of control. (voanews.com)

The nucleocapsids form with more newly synthesized RNA molecules, assembling like a puzzle. (futurelearn.com)

Short primers of DNA matching the complementary strand of the viral DNA template stick together, functioning as an artificial start site for DNA synthesis. (mayo.edu)

We show that knock-down of each single gene from multiple target vectors is achieved at an efficiency comparable to that obtained after transduction using single target viral vectors. (ejbiotechnology.info)

[ 1 ] The disease is usually a benign and inconsequential viral illness unless exposure occurs in utero. (medscape.com)

The viral nucleic acid can be single-or double-strand DNA or RNA. (biopharminternational.com)

The reported incidence of viral pneumonia (see the image below) has increased during the past decade. (medscape.com)
Depending on the virulence of the organism, as well as the age and comorbidities of the patient, viral pneumonia can vary from a mild, self-limited illness to a life-threatening disease. (medscape.com)
Viral pneumonia decreases in frequency in healthy young and middle-aged adults, but it then increases substantially among the elderly. (medscape.com)

The drug - known by the acronym DRACO - works by chemically targeting viral-infected cells and prompting them to self-destruct, eliminating the disease in the process. (voanews.com)

Removing viral contaminants from animal cell-culture derived biologicals is a major challenge of downstream purification because it involves laborious and time-consuming techniques that result in increased manufacturing costs. (biopharminternational.com)

Targeting one single gene can lead to the development of escape mutants or may be insufficient to silence redundant pathways. (ejbiotechnology.info)

Viral meningitis can occur in people of all present nonspecific symptoms, such as headache, ages, but it is more common in children5,6. (bvsalud.org)
A nonspecific viral prodrome is followed. (msdmanuals.com)

Later, it synthesizes a complementary strand of DNA using the previous DNA as a template. (futurelearn.com)

To convert RNA into DNA, they have a special enzyme, called reverse transcriptase, which gives the name to the family. (futurelearn.com)

DDX58/RIG-I, a sensor of cytoplasmic viral RNA and toll-like receptors (TLR) 3, 7, and 8, which bind RNA in endosomes, are conserved in pangolins. (frontiersin.org)
