Researchers identify new mechanism that impairs cancer cell proliferation and induces death

UAB and Vall d'Hebron researchers identified the mechanism by which inhibitors of the ERK5 protein kinase impair the proliferation of cancer cells and induce their death. The results, obtained using human cancer cell lines, demonstrate that ERK5 inhibition activates cytotoxic autophagy, a process that triggers cancer cell death, without affecting healthy cells. A combination of ERK5 inhibitors and chemotherapy could improve cancer treatment.

Do reactive oxygen species play a role in fighting COVID-19?

Serum-free thiols are known to reflect the activity of reactive oxygen species in the body, and researchers have been examining the difference in these thiols in COVID-19 patients.

Pandemic poses short- and long-term risks to babies, especially boys

The pandemic has created a hostile environment for pregnant people and their babies. Stress levels among expectant mothers have soared. Pregnant women with covid are five times as likely as uninfected pregnant people to require intensive care and 22 times as likely to die. Infected moms are four times as likely to have a stillborn child.

Research reveals the structure and function of a bifunctional protein that transports heme

Heme is an essential part of the protein hemoglobin, which colors human blood red. Heme also is crucial for cytochrome proteins, which power the cell. Humans, animals, plants and bacteria all use heme.

Researchers find a digital silver lining in failed COVID-19 drug trial

A clinical trial in which two test drugs failed to help patients with mild COVID-19 nevertheless had a silver lining: It proved the viability of a study model in which a medication's potential arrhythmic side effects are safely, effectively monitored without the participants ever setting foot in a hospital or clinic.

Cloth facemasks worn during exercise are unlikely to cause significant respiratory changes

A new study explored whether wearing masks either increased, reduced, or did not alter various respiratory variables.

Succinate receptor can be a potential target for cancer treatment

Cancer cells show unchecked rapid growth beyond tissue boundaries that is no longer stopped by normal control mechanisms. Due to this rapid growth, the metabolism of cancer cells is altered compared to that of cells that grow normally.

Trial identifies a drug that may benefit some patients hospitalized with COVID-19 pneumonia

A proof-of-concept trial led by the Universities of Birmingham and University Hospitals Birmingham NHS Foundation Trust has identified a drug that may offer benefit some patients hospitalized with COVID-19 pneumonia.

Researchers find muscle growth in some critically ill COVID-19 patients

Muscles appear to grow, rather than shrink, in some critically ill COVID-19 patients, finds new research being presented at Euroanaesthesia, the annual meeting of the European Society of Anaesthesiology and Intensive Care, held online this year.

As hospitals fill up, paramedics spend more time moving patients, less on emergencies

The night after Thanksgiving, a small ambulance service that covers a huge swath of southwestern Colorado got a call that a patient needed an emergency transfer from the hospital in Gunnison to a larger one with an intensive care unit 65 miles away in Montrose.

Gene key to excessive cell proliferation could be a potential target for fatal pulmonary hypertension

A gene that is overexpressed in some aggressive cancers also appears to be key to the excessive cell proliferation that thickens the walls of pulmonary arteries and ultimately causes the right ventricle of the heart to fail, scientists report.

New review examines the advances and future trends in sleep disorder measurement technology

Sleep disorders and insufficient sleep are major global problems contributing to, e.g., increased health care costs and sick leaves, and reduced quality of life. According to recent estimates, sleep apnea alone affects approximately 1 billion people worldwide, and up to half of the world’s population suffers from insomnia at some point in their lives.

Impact of exogenous antibody therapy by convalescent plasma against SARS-CoV-2

Researches have been investigating the possibility of using convalescent plasma to help patients recover from COVID-19.

Hyperbaric oxygen treatment quickly resolves severe breathing difficulties in COVID-19 patients

High pressure (hyperbaric) oxygen resolves severe breathing difficulties in COVID-19 patients much more quickly than standard therapy, taking an average of 3 rather than 9 days, reveal the results of a small comparative clinical trial published online in Emergency Medicine Journal.

Frequent cognitive impairments after 4-month follow-up in ICU COVID-19 patients

Results from a recent observational study published in the Journal Of The Neurological Sciences found that after a 4-month follow-up, ICU patients with severe COVID-19 illness were more likely to have mild cognitive impairment with features related to a diffuse encephalopathy than patients with mild infection who do not need a ventilator. Additionally, ICU patients experienced more significant impairment in executive function. All neurological deficits involve the peripheral nervous system.

Protein can protect the heart from damage following cancer treatment

Cancer treatment can be tough on the body, but for the patient to survive the cancer, it's often necessary to go through with the treatment anyway.

Evaluating the virucidal activity of blue LED light against SARS-CoV-2 infection

A new study provides some possible explanations to the mechanisms by which antiviral activity is exerted by blue LED light and indicated that the alteration of the SARS-CoV-2 spike protein requires the presence of photosensitizers.
