  • Dose-dependent and independent temporal patterns of gene responses to ionizing radiation in normal and tumor cells and tumor xenografts. (uchicago.edu)
  • The immune system controls it once it wakes up and starts making more copies of itself, and they take care of those new copies, but even the immune system doesn't do anything about that long-term sleeping form of the virus. (thenakedscientists.com)
  • Autoimmune hepatitis is liver inflammation that occurs when your body's immune system turns against liver cells. (sparrow.org)
  • When diagnosed and treated early, however, autoimmune hepatitis often can be controlled with drugs that suppress the immune system. (sparrow.org)
  • Just why the body turns against itself is unclear, but researchers think autoimmune hepatitis could be caused by the interaction of genes controlling immune system function and exposure to particular viruses or drugs. (sparrow.org)
  • These viruses included rotaviruses, enteric adenoviruses, Norwalk and Norwalk-like viruses (NLVs). (ijbiotech.com)
  • Cidofovir is an anti-viral drug that is effective against several viruses, including the human papilloma virus (HPV), which is implicated in the onset of cervical cancer. (cancerlive.net)
  • Recently, an article entitled Mechanisms of APOBEC3 mutagenesis in human cancer cells published in the sub-journal of "Nature" elaborated on the mechanism of action and confirmed the possibility of monkeypox virus prevention and treatment. (medicaltrend.org)
  • The researchers knocked out APOBEC3A and APOBEC3B genes from a series of cancer cell lines, and found that these cancer cell lines developed APOBEC3-related mutations over time, and that APOBEC3B is a cytosine deaminase targeting linear and hairpin structures. (medicaltrend.org)
  • The development of safe and efficient liver-specific gene delivery approaches offers new perspectives for the treatment of liver disease, in particular, liver cancer. (elsevierpure.com)
  • In another study published in the New England Journal of Medicine, the majority of 528 monkeypox patients exhibited systemic clinical features, including fever (62%) , lethargy (41%) , myalgia (31%) , and Headache (27%) , of which 41% were human immunodeficiency virus (HIV) -infected. (medicaltrend.org)
  • Among those, RNA viruses such us human immunodeficiency virus (HIV) and hepatitis C virus (HCV) are two of the main challenges for the global health in the 21st century. (hindawi.com)
  • When most people hear the word "virus," they think of disease-causing (pathogenic) viruses such as the common cold, influenza, chickenpox, human immunodeficiency virus (HIV), SARS-CoV-2 and others. (medicinenet.com)
  • Now researchers have found the novel virus for the first time in Swiss ticks. (sciencedaily.com)
  • Human parechovirus is a harmless virus which is encountered by most infants and displays few symptoms. (sciencedaily.com)
  • Signs and symptoms of autoimmune hepatitis vary from person to person and may come on suddenly. (sparrow.org)
  • Later, a trigger like stress, sunlight, or something else, may reactivate the virus and lead to new symptoms. (medicinenet.com)
  • An incubation period refers to the time between exposure to a virus (or other pathogen) and the emergence of symptoms. (medicinenet.com)
  • This paper describes the construction of 10 mutant HSV-1 viruses with deletion and insertion mutations in Vmw110. (microbiologyresearch.org)
  • Novel IL31RA gene mutation and ancestral OSMR mutant allele in familial primary cutaneous amyloidosis. (hiroshima-u.ac.jp)
  • Mutant virus vhs-1 (a gift of G. ... manufacturer's instructions. (moam.info)
  • The vaccinia virus, which British physician Edward Jenner used almost 200 years ago in his pioneering vaccinations against smallpox, is now used as a vector to carry the herpes or hepatitis viral coat gene into cultured mammalian cells. (biologywriter.com)
  • Diagnosing unexplained hepatitis remains a challenge, as exemplified by 74 cases of acute hepatitis of unknown etiology reported in children in the United Kingdom, 3 cases in Spain, and up to 5 possible cases in Ireland ( 5 ). (cdc.gov)
  • In the 1970s, the causes of acute non-bacterial gastroenteritis were identified and several viruses associated with the stools of patients suffering from gastroenteritis correlated with their clinical disease. (ijbiotech.com)
  • Other acute viral conditions, such as fulminant viral hepatitis, are also being studied. (institutimagine.org)
  • Viruses are the causative agent of multiple infectious diseases and are one of the leading causes of mortality in poor-resource countries. (hindawi.com)
  • Mice get this sleeping form of herpes, just like we do. (thenakedscientists.com)
  • The same trend was observed in other studies employing Lactobacillus as probiotics in mice infected with influenza viruses. (news-medical.net)
  • We are continuing our work on using CRISPR/Cas technology to cleave viral genomic DNA as a possible approach to the treatment of chronic diseases caused by human viruses, concentrating at present on Human Papilloma Virus 16 (HPV16), which causes malignant cervical, anal and head-and-neck cancers, as well as on HIV-1, the cause of AIDS.
