The risk of mortality based on the characteristics of EHOF was evaluated. Survival of study groups was ...

UVA Health researchers have received $2.8 million to advance their development of a high-tech way to save heart and dialysis patients from the need for multiple surgeries. Researchers Lian-Wang Guo, PhD, and K. Craig Kent, MD, are pioneering a quick and gentle technique to “paint” tiny nanoparticles on transplanted veins to prevent the veins from becoming clogged in the future. This type of blockage often causes cardiovascular and dialysis patients to require repeated surgeries; approximately half of all heart ...

The human vascular system, a complex network of blood vessels, plays an essential role in maintaining health. Understanding the molecular mechanisms underlying vascular development is important for tackling age-related disorders. The Forkhead box O (FOXO1) transcription factor is crucial in processes related to aging, cellular metabolism, and apoptosis. Despite its significance, the comprehensive regulation of FOXO1 across the genome in endothelial cells (EC) has not been investigated.   In a new paper published in iScience in February 2024, a research team from Kumamoto University ...

Scope For decades, robotic systems have played a pivotal role in nurturing the growth of tissue-engineered constructs in controlled environments through the provision of mechanical stimulation. The importance of physical stresses in tissue maturation is not only intuitive from our own bodily experiences but is also supported by a growing body of mechanotransduction research. However, experimental studies have predominantly remained confined to basic in vitro setups, hampering our ability to produce functional grafts that can translate into clinical practice. Emerging evidence suggests that replicating physiological stresses more faithfully could further enhance the functionality of tissue ...

mRNA vaccines developed against the spike glycoprotein of severe acute respiratory syndrome type 2 coronavirus (SARS-CoV-2), displayed remarkable efficiency in combating coronavirus 19 (COVID-19). These vaccines work by triggering both cellular and humoral immune responses against the spike protein of the virus. Cellular immunity may play a more protective role than humoral immunity to variants of concerns (VOC) against SARS-CoV-2, as it targets the conserved regions of spike protein and possibly cross-reacts with other variants.   Since a single spike epitope is recognized by multiple T-cell clones, the ...

Climate change is driving both the loss of biodiversity and the need for clean, renewable energy. It is also shifting where species are expected to live in the future. Yet these realities are rarely considered together. Where can clean energy projects be built without impacting the future habitat ranges of threatened and endangered species? A study from the University of California, Davis, examines this question by overlaying renewable energy siting maps with the ranges of two species in the southwestern United States: the iconic and climate-vulnerable ...

In the space of just a few seconds, a person walking down a city block might check their phone, yawn, worry about making rent, and adjust their path to avoid a puddle. The smell from a food cart could suddenly conjure a memory from childhood, or they could notice a rat eating a slice of pizza and store the image as a new memory.    For most people, shifting through behaviors quickly and seamlessly is a mundane part of everyday life.    For neuroscientists, it’s one of the brain’s most remarkable capabilities. That’s because different activities require the brain to use different combinations of its many regions and billions of neurons. How ...

By Gretchen Schrafft, Science Communications Specialist, Robert J. & Nancy D. Carney Institute for Brain Science PROVIDENCE, R.I. [Brown University] — Imagine a busy restaurant: dishes clattering, music playing, people talking loudly over one another. It’s a wonder that anyone in that kind of environment can focus enough to have a conversation. A new study by researchers at Brown University’s Carney Institute for Brain Science provides some of the most detailed insights yet into the brain mechanisms that help people pay attention amid such distraction, as well as what’s ...

The body's inability to produce enough insulin or use it effectively often results in type 2 diabetes (T2D), a chronic disease affecting hundreds of millions of people around the globe. Disease management is crucial to avoid negative long-term outcomes, such as limb amputation or heart disease. To counteract adverse consequences, it is crucial that patients have good knowledge about the day-to-day management of the disease.  A team of researchers in Portugal has now assessed how many patients – both insulin-treated and not insulin-treated – have this crucial knowledge about T2D. They published their findings in Frontiers in Public Health. “Our main motivation ...

Smaller class sizes in schools are failing to increase the resilience of children from low-income families, according to a study published in the peer-reviewed International Journal of Science Education. Data on more than 2,700 disadvantaged secondary (high) school students shows that minimizing pupil numbers in classrooms does not lead to better grades. Reducing class sizes could even decrease the odds of children achieving the best results, say the study authors. The quantity of teachers also does not increase the odds of pupils from the poorest backgrounds achieving academically, despite concerns over staff shortages in schools. Instead, the researchers ...

Transition metal selenides have been considered to be a good choice for electrocatalytic water splitting. In addition, Metal-organic frameworks (MOFs) have been used to make catalysts with good electrocatalytic capabilities. Traditionally, the MOF-derived selenides are produced via the self-sacrificing MOF template methods. However, this strategy is high-energy consuming, and it is difficult to precisely control the structure and component homogeneity of the product during pyrolysis. A research group of Wang-ting Lu, Fan Yu, and Yun Zheng ...

How extreme weather and climate events change is an intriguing issue in the context of global warming. As IPCC AR6 points out, cold extremes have become less frequent and less severe since the 1950s, mainly driven by human-induced climate change. However, cold extremes could also exhibit robust interdecadal changes at regional scale.   A recent study by researchers from the Institute of Atmospheric Physics, Chinese Academy of Sciences, presents robust interdecadal changes in the number of extreme cold days in winter over North China during 1989–2021, and the findings have been published in Atmospheric and Oceanic Science Letters. ...

This paper's objective is to show that the network of frequent relationships that is established between agents in coworking environments, through weak ties, increases the generation of ideas. Thus, the present work argues that collaborative spaces can expand individuals' creativity, as they constitute a social hub for exchanging experiences and visions between individuals from different social and professional backgrounds [Blagoev et al. (2019)]. Through frequent relationships and weak ties, these social connections allow individuals to access different levels of insights and inspirations that make it possible to ...

The chance sighting of a dead snake beside a sandy track in remote Western Australia, and the investigation of its stomach contents, has led Curtin University researchers to record the first known instance of a spotted mulga snake consuming a pygmy spiny-tailed skink, raising concerns for a similar-looking, endangered lizard species. Lead researcher Dr Holly Bradley from Curtin’s School of Molecular and Life Sciences said the discovery of the partially digested pygmy spiny-tailed skink within the snake had implications for the vulnerable western spiny-tailed skink species. “Found about 300km east ...
