The heart is the driving force of circulating blood in the body and pumps blood to the entire body by repeating contraction and relaxation of the heart muscles continuously. Human stem cells are used in the clinical therapies of a dead heart, which happens when a blood vessel is clogged or whole or a part of heart muscles is damaged. The clinical use of human bone marrow-derived mesenchymal stem cells (BM-MSCs) have been expanded but failure of the transplanted stem cells in the heart still remains a problem. Recently, an international joint research team of POSTECH, Seoul St.
Though many negative repercussions of human immunodeficiency virus infection can be mitigated with the use of antiretroviral therapy (ART), one area where medical advances haven't made as much progress is in the reduction of cognitive impacts. Half of HIV patients have HIV-associated neurocognitive disorders (HAND), which can manifest in a variety of ways, from forgetfulness and confusion to behavior changes and motor deficiencies.
HOUSTON - (March 27, 2020) - One nanotube could be great for electronics applications, but there's new evidence that two could be tops.
Rice University engineers already knew that size matters when using single-walled carbon nanotubes for their electrical properties. But until now, nobody had studied how electrons act when confronted with the Russian doll-like structure of multiwalled tubes.
MAYWOOD, IL--Large events are cancelled, restaurants and non-essential businesses are closed, and in many states, residents have been asked to shelter in place, all to limit the spread and impact of the COVID-19 virus. But are strict and early isolation and other preventative mandates really effective in minimizing the spread and impact of a disease outbreak?
URBANA, Ill. - Pigs have better feed conversion rates with copper in their diets, but until now, scientists didn't fully understand why. Existing research from the University of Illinois shows copper doesn't change fat and energy absorption from the diet. Instead, according to new research, the element seems to enhance pigs' ability to utilize fat after absorption, resulting in increased energy utilization of the entire diet.
As the COVID-19 pandemic unfolds, inaccurate medical information has flooded social media and other channels. One potentially lethal example is that patients who take renin-angiotensin system (RAS) blockers, particularly angiotensin II type 1 receptor blockers (ARBs), may be more susceptible to the virus.
In a study published online yesterday focused on the medical products industry - which includes medical devices, pharmaceuticals and biologics - a group of researchers found that, compared to firms with all-male boards, firms with female directors announced high-severity product recalls 28 days sooner. This is a 35% reduction in the time between when a firm was first made aware of the defect and when the firm decided to recall the defective product.
Researchers have developed a triad of innovative tools to engineer low-pH-tolerant yeast Issatchenkia orientalis for production of valuable bioproducts from renewable biomass.
A paper published in Metabolic Engineering outlines the study's three-pronged approach and its importance to the field of sustainable chemical production.
WASHINGTON--A plant-based diet can help prevent and manage asthma, while dairy products and high-fat foods raise the risk, according to a new review published in Nutrition Reviews.
Asthma is a common chronic condition in which the airways become narrow and inflamed--sometimes leading to difficulty with breathing, coughing, wheezing, and shortness of breath.
UNIVERSITY of Huddersfield experts have made stark warnings about the impact of coronavirus on local authorities. A major increase in mortality rates and staff absences will mean a struggle to issue death certificates, leading to a bottleneck in burials and cremations, with mortuaries filled beyond capacity.
Aminoglycoside antibiotics are critically important for treating several types of infections with multi-resistant bacteria. A completely new resistance gene, which is likely to counteract the newest aminoglycoside-drug plazomycin, was recently discovered by scientists in Gothenburg, Sweden.

The remaining "bound water" on cotton surfaces cross-link single fibers of cotton, causing hardening after natural drying, according to a new study conducted by Kao Corporation and Hokkaido University. This provides new insight into unique water behaviors on material surfaces and helps us develop better cleaning technologies.
