Angiotensin News and Research

RSS

Angiotensin is an oligopeptide in the blood that causes vasoconstriction, increased blood pressure, and release of aldosterone from the adrenal cortex. It is a powerful dipsogen. It is derived from the precursor molecule angiotensinogen, a serum globulin produced in the liver. It plays an important role in the renin-angiotensin system.

Electrical impulses may help reduce the complications of arterial hypertension

Why is COVID-19 more severe among adults than children?

Researchers in Switzerland and Australia have reviewed some of the mechanisms proposed regarding why coronavirus disease 2019 (COVID-19) is generally less severe among children than among adults.

COVID-19 may be linked to acute appendicitis in children

Researchers at the University of Virginia have recently presented a case series pointing to a potential association between infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the development of acute appendicitis in children.

Transmission dynamics of SARS-CoV-2 in children: an Indian case study

Researchers have studied the primary contacts of COVID-19 positive children in India in May 2020 and found all children to be asymptomatic, and only four of the parents became positive. Although this suggests lower transmission from children, no recommendations can be made yet on school reopening.

Topoisomerase 1 inhibition prevents SARS-CoV-2-induced inflammation and death in animal models

A new study indicates that the topoisomerase 1 (Top1) is intimately related to the lethal inflammation associated with SARS-CoV-2 infection in a large proportion of cases.

Low testosterone can increase risk of severe COVID-19 in males

Researchers from the USA and Saudi Arabia describe the direct correlation between testosterone levels, inflammatory cytokines, disease progression, and worse outcomes in male COVID-19 patients.

Can melatonin help prevent severe COVID-19?

A team of researchers at the University of Toronto in Canada has found that melatonin can be an adjuvant to augment the efficacy of anti-SARS-CoV-2 vaccines. They believe that the drug is a potential “silver bullet” to combat the COVID-19 pandemic.

New and sudden headaches may be a symptom of COVID-19

Researchers report a case of a young male patient who came in with a headache to an emergency room. He had increased intracranial pressure and tested positive for SARS-CoV-2, suggesting new headaches during the pandemic should not be ignored.
