A microRNA network is the putative mediator of reductive stress in the heart

Posted: 06 Aug 2021 02:19 PM PDT

Last year, researchers reported that reductive stress -- an imbalance in the normal oxidation/reduction homeostasis -- caused pathological changes associated with heart failure in a mouse model. Now, researchers describe the putative molecular regulators of this pathological chronic reductive stress -- a microRNA network.

Trials reveal efficacy and safety of oral drug for treating anemia associated with kidney disease

Posted: 06 Aug 2021 02:19 PM PDT

Pooled results from phase 3 clinical trials demonstrate that roxadustat is efficacious and may be comparable to placebo in studies done to date for treating anemia in patients with chronic kidney disease who do not require dialysis.

Do vitamin D supplements offer kidney-related benefits for individuals with high diabetes risk?

Posted: 06 Aug 2021 02:19 PM PDT

In a clinical trial of individuals at high risk for developing type 2 diabetes, which is the leading cause of kidney disease, vitamin D supplementation did not have significant effects on kidney health. As participants were not selected according to baseline vitamin D levels, investigators cannot exclude a kidney benefit for individuals with vitamin D deficiency.

Face masks protect against aerosolized toxins from algal blooms, study finds

Posted: 06 Aug 2021 02:19 PM PDT

Intense blooms of toxic algae are becoming common occurrences along the coast of Florida and elsewhere. Results from a new study found that wearing the face mask everyone has become accustomed to during the COVID-19 pandemic may help protect against these airborne toxins too.

New device can diagnose COVID-19 from saliva samples

Posted: 06 Aug 2021 12:59 PM PDT

A new device can detect SARS-CoV-2 from saliva in about an hour. Researchers report that the diagnostic is just as accurate as PCR tests and can identify COVID-19 variants.

New drug combo shows early potential for treating pancreatic cancer

Posted: 06 Aug 2021 07:45 AM PDT

A team of researchers has developed an immunotherapy strategy that can eliminate pancreatic tumors in mice. The new therapy, a combination of three drugs that boost the body's immune defenses against tumors, is expected to enter clinical trials later this year.

Licensed drug could reduce SARS-CoV-2 infection by up to 70 per cent, lab study reveals

Posted: 06 Aug 2021 07:44 AM PDT

A licensed drug normally used to treat abnormal levels of fatty substances in the blood could reduce infection caused by the SARS-CoV-2 virus by up to 70 per cent, a new study in the laboratory reveals.

To do or not to do: Cracking the code of motivation

Posted: 06 Aug 2021 07:43 AM PDT

By manipulating the dopamine receptors of monkeys and studying their behavior, scientists reveal how our brain makes us feel motivated.

Histone deacetylase inhibitor gel shows promise for the treatment of patients with basal cell carcinoma

Posted: 06 Aug 2021 07:43 AM PDT

Remetinostat, a topical cream and first-in-class inhibitor of histone deacetylation, showed signs of clinical efficacy in patients with basal cell carcinoma.

Antibodies to SARS-CoV-2 remain stable, or even increase, seven months after infection

Posted: 06 Aug 2021 07:43 AM PDT

The levels of IgG antibodies against SARS-CoV-2 Spike protein remain stable, or even increase, seven months after infection, according to a follow-up study in a cohort of healthcare workers. The results also support the idea that pre-existing antibodies against common cold coronaviruses could protect against COVID-19.

Novel research identifies gene targets of stress hormones in the brain

Posted: 06 Aug 2021 07:43 AM PDT

Chronic stress is a well-known cause for mental health disorders. New research has moved a step forward in understanding how glucocorticoid hormones ('stress hormones') act upon the brain and what their function is. The findings could lead to more effective strategies in the prevention and treatment of mental health disorders.

Light therapy helps burn injuries heal faster by triggering growth protein

Posted: 06 Aug 2021 07:43 AM PDT

The research found that photobiomodulation -- a form of low-dose light therapy -- sped up recovery from burns and reduced inflammation in mice by activating a protein that controls cell growth and division.

Newly developed, bioinspired cell delivery vehicles

Posted: 06 Aug 2021 07:43 AM PDT

A research team has designed nanocontainers made of sugar and protein components. These containers are taken up by cells through natural processes and can thereby transport substances that normally cannot penetrate the cell membrane -- such as drugs or labelled substances for the investigation of cell functions -- into cells.

Scientists reverse a key hallmark of motor neurone disease in the laboratory

Posted: 05 Aug 2021 06:15 PM PDT

Scientists have studied how proteins accumulate in the wrong parts of brain cells in motor neurone disease, and have demonstrated how it might be possible, in some cases, to reverse this.

New study examines privacy and security perceptions of online education proctoring services

Posted: 05 Aug 2021 03:06 PM PDT

Educational institutions have had to transition to remote learning and exam taking. This has led to an increase in the use of online proctoring services to curb student cheating. In a first-of-its-kind study, researchers explored the security and privacy perceptions of students taking proctored exams.

The future of medicine is nearer thanks to researchers’ invention

Posted: 05 Aug 2021 03:06 PM PDT

Researchers recently unveiled their discovery of a new process for making RNA. The resulting RNA is purer, more copious and likely to be more cost-effective than any previous process could manage. This new technique removes the largest stumbling block on the path to next-generation RNA therapeutic drugs.

New drug molecules could prevent skin aging caused by sun exposure

Posted: 05 Aug 2021 11:11 AM PDT

Two new molecules that generate minute amounts of the gas hydrogen sulfide have been found to prevent skin from aging after being exposed to ultraviolet light found in sunlight. Sunburn is a major cause of premature aging in skin, and a primary risk factor for skin cancer, and other skin problems associated with aging. Now, an international research team has made inroads towards being able to reverse or delay this damage for the first time.

AI knows where your proteins go

Posted: 05 Aug 2021 08:54 AM PDT

Researchers have found that a machine learning algorithm can predict the location of actin-associated proteins in lamellipodia and other subcellular structures based solely on the location of actin itself. This approach could be useful for rapid analysis of microscopy images, and potentially as a substitute for using fluorescent stains to detect proteins within cells.

To advance human rights, consult neuroscience

Posted: 05 Aug 2021 07:44 AM PDT

Scholars found that brain science bolsters long-held notions that people thrive when they enjoy basic human rights such as agency, freedom from want, and freedom from fear.
