Exercise hormone could have a therapeutic effect on COVID-19 patients

A study conducted by researchers at São Paulo State University suggests that irisin, a hormone secreted from muscles in response to exercise, could have a therapeutic effect on COVID-19 patients.

Research provides insight into how muscles and fat tissue communicate to improve fitness

Why does exercise training make you more fit? It's well established that exercising enhances insulin sensitivity and improves our metabolism that, in turn, increases exercise performance. But the biological mechanisms underlying this adaptation are not fully understood.

Keto diet could be beneficial for elderly COVID-19 patients

A recent study by researchers at Yale School of Medicine, New York University Langone Health and Washington University School of Medicine, claims that the ketogenic diet (high fat, low carbohydrate diet) is capable of mitigating clinical outcomes of coronavirus disease 2019 (COVID-19) in elderly people by improving immune-metabolic functions and reducing inflammation. The study is currently available on the bioRxiv* preprint server.

Ghrelin may help protect the elderly population from muscle loss

The hormone, ghrelin, may help protect the elderly population from muscle loss, according to a study being presented at e-ECE 2020. The study found that administering a particular form of ghrelin to older mice helped to restore muscle mass and strength.

Estradiol appears to help in female SARS-CoV-2 infection

A new study published on the preprint server medRxiv in August 2020 shows that the risk of infection is high for pre-menopausal women but the risk of death is much higher for men in the same age group and throws light on the protective nature of estradiol therapy in post-menopausal women.

Study shows how aging fat cells lead to lifestyle diseases

No matter how much we try and fight it, aging is a part of life. High cholesterol, diabetes, and fatty liver, the collection of conditions referred to as lifestyle diseases, all become more commonplace as we get older.

Bioluminescent molecule in fireflies shines light on mitochondrial activity

The mitochondria provide energy for our cells, yet their role in many diseases is still poorly understood. Thanks to a bioluminescent molecule, scientists at EPFL can observe them at work in living mammals.

Study: Oats and rye brans reduce weight gain, hepatic inflammation

In a newly published experimental study, the consumption of dietary fibre from oat and rye brans supported the growth of beneficial gut microbiota, which in turn ameliorated cholesterol metabolism, enhanced gut barrier function and reduced hepatic inflammation.

BMI should be assessed in management of COVID-19 patients

A new study published on the preprint server medRxiv* in June 2020 reports that obesity is a risk factor of composite poor outcome of COVID-19 disease. On the other hand, COVID-19 patients with 'composite poor outcome' have higher BMI. Therefore, BMI should be assessed in the management of COVID-19 patients, and special attention should be given to patients with obesity.

Novel vaccine that removes aged immune cells mitigates metabolic disorders in obese mice

Aging is a multifaceted process that affects our bodies in many ways. In a new study, researchers from Osaka University developed a novel vaccine that removes aged immune cells and then demonstrated an improvement of diabetes-associated metabolic derangements by vaccinating obese mice.
