Our body’s fat metabolism plays a vital role in energy production in our body. A research team at the University of Basel, Switzerland, has discovered a molecular switch that regulates lipid metabolism in our cells. This switch controls the storage or conversion of lipids into energy. All organisms need energy to live. We get energy from various components of our food. Our body uses a part of this energy directly and stores the rest. While glucose serves as an immediately available energy source, fats are stored as energy reserve in form of lipid droplets within our cells. When the body needs energy from these fat stores, lipids are transported ...

Artificial intelligence can predict on- and off-target activity of CRISPR tools that target RNA instead of DNA, according to new research published in Nature Biotechnology. The study by researchers at New York University, Columbia Engineering, and the New York Genome Center, combines a deep learning model with CRISPR screens to control the expression of human genes in different ways—such as flicking a light switch to shut them off completely or by using a dimmer knob to partially turn down their activity. These precise gene controls could be used to develop new CRISPR-based therapies.  CRISPR is a gene ...

It’s estimated that around 25% of patients who have a cardiac arrest and receive cardiopulmonary resuscitation (CPR) in a normal hospital setting will survive. Those odds shoot up to 50% for patients who receive CPR during or in the immediate period following surgery, where they are closely monitored by specialists who know their medical history and can intervene without delay. But it’s unclear whether that trend applies to frail patients, who are often older and at a higher risk of experiencing CPR-related trauma and complications. Such uncertainty has led some doctors ...

Induced pluripotent stem (iPS) cells have a great impact on biology and medicine, and they are expected to improve regenerative medicine. Since 2014 when a sheet of retinal pigment epithelial cells derived from iPS cells was transplanted into patients with age-related macular degeneration, clinical trials have been conducted with various cell types derived from iPS cells. While iPS cells derived from healthy individuals have been used so far, it is expected that transplantation therapy using iPS cells can be enhanced through genetic modification in the future.   Therefore, we addressed this possibility by utilizing a Fabry disease mouse model, ...

The Ternary Space maps and digitally connect the urban physical and social ...

Bluetongue virus, an incurable cattle and sheep-killing disease, is spread by tiny flies once thought to disappear in winter. New research demonstrates that though they are harder to find when it’s cold, they remain active.  Bluetongue virus is common in cattle throughout most of the United States, particularly in the southwestern U.S. with nearly 20% of some California cattle herds infected. Due to concerns about spread of this virus, exports of U.S. cattle and cattle products to parts of Europe and Asia have been restricted to prevent contamination.   However, not all infected animals die. The main symptoms are elevated temperatures, lethargy, ...

Recurrent cystitis (RC) is a frequent infection of the urinary tract and bladder, which is highly prevalent among postmenopausal women. Under healthy circumstances, the human vagina is home to a host of beneficial intestinal bacteria, such as Lactobacilli. However, in the case of urinary tract infections (UTIs), there is a decrease in the abundance of Lactobacilli and an increase in pathogenic bacteria, such as Escherichia coli (E. coli). Previous studies have shown that changes in vaginal microbiota are a key underlying reason for the development of UTIs. Further, a few clinical trials have demonstrated the utility of Lactobacillus-containing vaginal ...

Amazon river dolphins are under threat from fishing and proposed new dams and dredging, research shows. Scientists used satellite tags to track eight dolphins in the Peruvian Amazon, to discover where they went in relation to fishing areas and proposed dams and dredging sites. On average, 89% of the dolphins’ home “range” (the area they live in) was used for fishing. Dolphins were found to be an average of 252km from the nearest proposed dam and 125km from the nearest proposed dredging site. While these are significant distances, the dolphins’ ranges ...

A study involving more than 745,000 adolescents from 41 countries across Europe and North America identified an increase in the amount of teenagers who underestimate their body weight.   Tracking data from 2002 to 2018, the peer-reviewed findings, published today in Child and Adolescent Obesity, demonstrate a noticeable decrease in those who overestimate their weight too.   The team of international experts, who carried out the research, warn these shifting trends in body weight perception could reduce the effectiveness of public health interventions aimed at weight reduction in young people.   “During this impressionable age, body weight perception ...

Babies and puppies have at least two things in common: aside from being newborns, they promote a positive emotional state in human mothers, leading them to articulate better when they speak. This finding is the result of research by an international team1 that included Alejandrina Cristia, a CNRS Researcher at the Laboratoire de sciences cognitives et psycholinguistique (LSCP) (CNRS/EHESS/ENS-PSL). Scientists studied the vocal behaviour of ten mothers to better understand why mothers articulate more when speaking to infants. Participants were asked to ...

COVID-19 vaccination helped reduce disparities in disease incidence between low- and high-income communities, according to a new analysis led by Cedars-Sinai investigators. While lower-income communities had lower vaccination rates than higher-income communities, the impact of vaccination on disease incidence was larger in lower-income communities. As a result, investigators say, vaccination led to reduced income-related disparities in COVID-19 incidence.  The findings were published today in the Morbidity and Mortality Weekly Report, a publication of the Centers for Disease Control and Prevention (CDC). “This study is a unique demonstration ...

Scientists have successfully tested a novel way of boosting honey bees’ immune systems to help them fend off deadly viruses, which have contributed to the major losses of the critical pollinator globally. In a new study, the research team, which includes entomologists with the University of Florida, the Agricultural Research Service-USDA, Louisiana State University and the University of Nebraska-Lincoln, showed that prompting honey bees’ cells to produce free radicals helped the bees weather a host of viruses. In fact, the treatment greatly reduced, and in some cases, nearly eliminated virus ...

Leesburg, VA, June 30, 2023—According to an accepted manuscript published in ARRS’ own American Journal of Roentgenology (AJR), using an automated deep-learning AI tool, as well as weight-based volumetric thresholds, might afford large-scale evaluation for splenomegaly on CT examinations performed for any indication. Noting that, historically, the standard linear splenic measurements used as a surrogate for splenic volume yielded suboptimal performance in detecting volume-based splenomegaly, “the ...

Leesburg, VA, June 30, 2023—According to an accepted manuscript published in ARRS’ own American Journal of Roentgenology (AJR), a deep learning-based model using initial chest radiographs predicted 30-day mortality in patients with community-acquired pneumonia (CAP), improving upon the performance of an established risk prediction tool (i.e., CURB-65 score). “The deep learning (DL) model may guide clinical decision-making in the management of patients with CAP by identifying high-risk patients who warrant hospitalization and intensive treatment,” concluded first author Eui Jin Hwang, MD, PhD, from the department of radiology at Seoul National ...

(Santa Barbara, Calif.) — The universe is expanding; we’ve had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate.  It’s no small feat to measure the rate at which objects move away from each other across vast distances. Since the discovery of cosmic expansion, its rate has been measured and re-measured with increasing precision, with some of the latest values ranging from 67.4 up to 76.5 kilometers per second per megaparsec, which relates the recession velocity (in ...
