Study reveals high prevalence of post-pandemic fatigue and sleep disturbances

Disrupted sleep and anxiety may be an ongoing issue for many people after the pandemic, whether due to COVID-19 directly or to the stress and anxiety caused by the global pandemic, and may contribute to the fatigue commonly reported by people with Post-COVID-19 Syndrome (PCS, or 'long COVID').

Modifiable cardiovascular risk factors linked to unstable coronary artery plaques

Cardiovascular risk factors are linked to higher risk of heart disease, but it has been unknown how they are related to abrupt closure of the coronary arteries leading to heart attack and sudden cardiac death.

Chemotherapy leaves early genomic fingerprints in childhood tumors

Nearly half of childhood tumors treated with common types of chemotherapy showed detectable DNA changes linked to treatment within 18 months, according to a new international study led by The Hospital for Sick Children (SickKids).

RNA-based testing can improve detection of key lung cancer biomarkers

New research has shown that RNA-based testing can improve the detection and interpretation of clinically actionable genomic alterations leading to MET exon 14 skipping in lung cancer patients—important biomarkers that may be missed by DNA-only approaches.

Review expands the role of selenium metabolism in ferroptosis

For decades, selenium has been recognized as an essential micronutrient, and glutathione peroxidase 4 (GPX4)-a selenium-containing enzyme-has been widely regarded as the central guardian against ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation.

Time zone changes disrupt vital gut bacteria during travel

A dream holiday, an exotic destination, a long-haul flight, and finally some well-deserved rest. The problem is that many travelers arrive at their destination only to spend the first days of their vacation struggling with fatigue, sleep disturbances, low energy levels, and digestive issues.

New mechanism behind chemotherapy resistance in ovarian cancer discovered

Scientists at The Wistar Institute have identified a new mechanism behind the chemotherapy resistance that makes ovarian cancer so lethal.

Lifestyle changes improve MASLD by suppressing key molecular pathway

Lifestyle modification is the cornerstone of managing metabolic dysfunction-associated steatotic liver disease (MASLD), a growing cause of chronic liver disease worldwide.

Compact genetic switch enables targeted gene therapy for epilepsy

Epilepsy affects over 50 million people worldwide, making it one of the most common neurological disorders.

Study reveals unexpected mechanism driving extreme antibiotic resistance

A patient with a severe infection is prescribed a potent antibiotic. Hopes for improvement are high, but just after treatment is given, resistance to the drug increases thousands of times. How could this happen?

Proactive telehealth program helps cancer patients quit smoking

For patients diagnosed with cancer, continuing to smoke during treatment may shorten survival.

New bacterial control strategy helps revive failing last-line antibiotics

Antimicrobial resistance is one of the world's most alarming public health challenges, because the multidrug-resistant (MDR) gram-negative bacteria increasingly render even last-line antibiotics ineffective, leading to substantially higher mortality rates.

Short-term immunosuppressive therapy briefly restores autism-like brain changes in adult mice

A new mouse study led by UCLA Health suggests that inflammation during pregnancy can trigger autism-like changes in offspring, but also that those brain and behavior effects may be rapidly but temporarily reversible in adulthood with a short-term dose of the immunosuppressive drug rapamycin.

Emerging PPAR therapies offer new hope for primary biliary cholangitis

Primary biliary cholangitis is a rare autoimmune disease that affects the liver and can progress to cirrhosis. It occurs when the immune system attacks the small bile ducts within the liver. As a result, bile builds up, leading to inflammation and progressive liver damage. Although a first-line treatment exists, 40% of patients do not respond adequately to it or cannot tolerate it, so new treatment options need to be developed.

Dormant melanocytes found in vitiligo offer hope for future repigmentation therapies

Vitiligo is an autoimmune disease in which the body's immune system attacks and destroys melanocytes, the cells that produce the skin pigment melanin. Once the melanocytes are gone, the skin turns white, leading to the characteristic skin patches of the disease.

Study reveals regional disparities in Brazilian childhood leukemia mortality

An international study involving LMU found regional differences in childhood lymphoid leukemia mortality across Brazil.

Study finds greater social jetlag linked to a later eating pattern

In a 14-day study of 101 healthy UK adults, greater social jetlag was associated with a later distribution of energy intake, particularly greater late-evening intake among women. The effects were modest, varied by sex and day type, and did not establish whether total daily energy intake differed between groups.

Ancient immune protein C3 boosts cancer immunotherapy within tumors

An ancient molecule that existed long before the blood circulation system evolved, has been found to support cancer immunotherapy.

Spermidine boosts key cellular processes linked to aging in early research

This review finds that spermidine supports autophagy, mitochondrial function, and healthspan in experimental models, while observational studies link higher dietary intake to lower mortality. However, human trials have produced limited and mixed results, leaving its clinical role in healthy aging unresolved.

Thymulin curbs age-related inflammation and slows breast tumors in mice

Thymulin reduced age-associated inflammatory myeloid cells and slowed breast-tumor growth in aged mice by suppressing NF-κB signaling. The peptide also restored anti-PD-L1 responsiveness in aged mouse models, while human cell and tumor data supported an age-linked inflammatory myeloid profile.
