Despite advances in heart failure (HF) treatment, risks remain high, linked to dysfunction in the NO-sGC-cGMP pathway which vericiguat aims to correct by enhancing cGMP levels, thus reducing oxidative stress and improving heart function. Clinical trials, including SOCRATES-REDUCED and VICTORIA, have shown vericiguat to be effective in patients with reduced ejection fraction (HFrEF), while its benefits for those with preserved ejection fraction (HfpEF) are still under investigation.
Alzheimer's disease (AD) significantly contributes to elderly mortality worldwide, with current treatments still under development. Stem cell therapy, offering advantages over drug therapies and other treatments, shows great promise. Four primary stem cell types are utilized in AD therapy: neural, mesenchymal, embryonic, and induced pluripotent stem cells, each with applications across cellular, animal model, and clinical levels. Research has predominantly focused on the cellular and animal model stages, with less progress at the clinical stage. Future research should broaden the types of stem cells studied, integrate cross-disciplinary approaches with other diseases, and aim for more timely and personalized stem cell therapies for AD.
Migraine, a severe headache disorder linked to the trigeminal vascular system, greatly affects individuals' lives. Despite the introduction of various treatments, not all patients see significant improvement. The success of CGRP-targeted therapies emphasizes the need for research into the mechanisms of migraine to develop effective treatments. This review highlights potential therapeutic targets such as PACAP, adenosine, DOR, potassium channels, TRP, and ASIC channels, suggesting that understanding these mechanisms could lead to new treatments and better patient care.
Monarch butterflies fly more than 2,000 miles from Canada to central Mexico each year, but only 30% survive the trip. Researchers have found that those with larger white spots on their wings are more successful and suggest that large white spots might have evolved to make wings more aerodynamic.
Reports of household cleaner ingestion in health behavior surveys during COVID-19 primarily come from problematic respondents, such as those who are inattentive, dishonest, or prone to systematically answering "yes" to all questions. These findings highlight the importance of employing methods in survey research to enhance measurement accuracy and prevent such respondents from compromising the validity of public health and medical studies.
This systematic review of 13 papers shows that most interventions aimed at reducing conspiracy beliefs are inneffective. However, this analysis suggested that interventions that occurred before participants were exposed to conspiracy beliefs, or attempts to develop critical thinking skills in participants, could potentially help counter conspiracy beliefs.
Ethnographic reports of 63 different foraging societies around the globe reveal that women had a key role in hunting. These conclusions upend the paradigm that women in foraging societies gathered whereas men hunted, and support a re-analysis of the division of labor in these cultures.
This study showed that sleep quality is the most influential effector on five aspects of quality of life: wellbeing, life satisfaction, subjective health, work stress and happiness. While sleep duration and social jetlag are undoubtedly important, they are less impactful on our quality of life than obtaining a good night’s sleep.
The first research stations in Antarctica were set up in the late 19th century, marking the beginning of a long history of scientific exploration on the continent. Over the years, numerous stations have been established, significantly advancing our knowledge of Antarctic ecosystems, climate, and geophysical processes, even in its most extreme environments. This particular study focuses on pollution and contamination patterns observed around Australia's Casey Station from 1997 to 2015. It reports elevated concentrations of metals, hydrocarbons, and polychlorinated biphenyls (PCBs), all exceeding recommended upper limits. The findings suggest that research stations in Antarctica could represent a moderate ecological threat to the marine ecosystems they are part of.
This study, which analyzed over 700,000 English news articles and utilized five major independent indexes of peacefulness, demonstrates that natural language processing (NLP) and machine learning techniques can predict a country's level of peacefulness based on the prevalence of certain words in its news publications. The findings pave the way for further research into whether this approach is applicable to news articles in other languages and to explore the social factors that determine the vocabulary used in media across various nations.
Data collected from over 11,000 stations monitoring the ocean indicate that the surface layer of our oceans is contaminated with approximately 82 to 358 trillion plastic particles. These particles collectively weigh between 1.1 and 4.9 million tonnes. The findings highlight the critical necessity of cutting down on worldwide plastic production and usage, alongside amplifying recycling efforts.
She is an icon in the field of biomaterilas. She was recently elected to the National Academy of Sciences. She was previously elected to the National Academy of Engineering and the National Academy of Medicine and is the first Johns Hopkins faculty member to be elected to all three National Academies.
Joule, a sister journal to Cell, is a home for outstanding and insightful research, analysis and ideas addressing a key global challenge: the need for more sustainable energy. Joule is a distinctive and forward-looking journal, bridging disciplines and scales of energy research. Joule connects all who are researching and analyzing the challenges — scientific, technical, economic, policy and social — of providing sustainable energy solutions. Joule spans scales of energy research, from fundamental laboratory research into energy conversion and storage up to impactful analysis at the global level. Joule will purposefully highlight and amplify the implications, challenges and opportunities of novel energy research for different groups working across the entire spectrum of the field.
