Singapore researchers discover protein that protects parathyroid glands from excessive growth, suggesting potential drug-based strategies to treat hyperparathyroidism and other relevant tumours.
In intramolecular SF (iSF), the strong coupling nature and confinement of diffusional separation of 1(TT) limits the extraction and harnessing of triplet energy. A series of iSF-capable dibenzopentalene derivatives (DBPs) have been synthesized and their photoinduced dynamics are monitored. Intramolecular singlet fission occurs in DBPs with consecutive 1(TT) separation in polycrystalline film with ~100% yield, suggesting the strong intermolecular coupling from the closely packing configuration in...

A research group led by Prof. XU Jie from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences has developed a surface acidity -- and selectivity-tunable manganese oxide catalyst using a surface modification technique.
Recently, Chengzhi Shi (now at Georgia Tech), Rongkuo Zhao, Sui Yang, Yuan Wang, and Xiang Zhang from the University of California, Berkeley and Long Yang, Hong Chen, and Jie Ren from Tongji University discover and experimentally observe the existence of acoustic spin in airborne sound waves.
Young Australians providing care for family members with mental illnesses, alcohol and drug addictions are struggling to keep up with their studies, according to new research.The study by Flinders University and UNSW found the problem will continue without improved flexibility in schools and personalised intervention programs.
Cancer therapies that use immune cells to trigger the body to attack tumors could be improved by a molecule that boosts their function, research from the University of Edinburgh suggests. Studies with mice have found the improved therapies produced a powerful anti-cancer immune response, which led to tumors shrinking.
Eight percent of the population suffer dysphagia or difficulty in swallowing food and this could rise to 80% among the elderly or in cases of neurodegenerative diseases. The University of the Basque Country's Texture Analysis Laboratory (LaTEX) has published a paper in the Food Hydrocolloids journal pointing to the poor standardization of thickened foods.
A perceived inability to act on symptoms could signify a life-threatening situation, according to research published today in the European Journal of Cardiovascular Nursing, a journal of the European Society of Cardiology (ESC). Most deaths from heart attack occur in the first few hours after the start of symptoms. Quick treatment is crucial to restore blood flow to blocked arteries and save lives.
Friends on social media such as Facebook can be a great source of comfort during periods of stress. However, if they don't receive any support offline, stressed users are at risk of developing a pathological dependence on the social networking site -- the so-called Facebook addiction. This is the result of a study conducted by a team of the Mental Health Research and Treatment Center at Ruhr-Universität Bochum (RUB), headed by Dr. Julia Brailovskaia.
Children and adolescents with long-term obesity have increased arterial stiffness by their late teens, a study of more than 3,000 children followed from age 9 to 17 shows. These results, in the researchers' view, call for more initiatives to reduce teenage obesity.
It is difficult for doctors to accurately assess avalanche victims who arrive at hospital suffering cardiac arrest: has the patient effectively suffocated, or is there a realistic prospect of survival if the patient is properly rewarmed? The correct initial assessment is crucial: it ensures that patients with a viable chance of survival are properly rewarmed, while also preventing unnecessary medical intervention in cases where survival is not possible.
Professor Dong-Woo Cho of Mechanical Engineering, Professor Jinah Jang of Creative IT Convergence Engineering, and Ms. Hyeonji Kim at POSTECH, collaborated with Professor Hong Kyun Kim of Ophthalmology at Kyungpook National University School of Medicine, 3D printed an artificial cornea using the bioink which is made of decellularized corneal stroma and stem cells. Because this cornea is made of corneal tissue-derived bioink, it is biocompatible, and 3D cell printing technology recapitulates the corneal microenvironment... Читать дальше...
A new Rutgers-led study finds that by adding a few subtle cues to prenatal care waiting rooms, such as photos of men and babies, and pamphlets and magazines aimed toward men, OBGYNS can get fathers more involved in prenatal care and increase healthier outcomes for women and infants.
'Subtle things, such as imagining how someone else would feel, can have a huge impact on creativity in general,' says UConn's Kelly Herd.
Common and rare SORLA single nucleotide polymorphisms have been associated with the development of Alzheimer's disease. So far, SORLA has been mainly studied in neurons, but the new study focused on SORLA's role in cancer cells. Led by Academy Professor Johanna Ivaska, researchers from the University of Turku in Finland observed that SORLA was highly expressed in HER2 positive cancers. Removing SORLA from cancer cells severely impaired the oncogenic fitness of HER2 positive cancers.
Research finds that people with substance-use problems who read a message describing addiction as a disease are less likely to report wanting to engage in effective therapies, compared to those who read a message that addiction behaviors are subject to change. The finding could inform future public and interpersonal communication efforts regarding addiction.
Wood-living beetles that use oak trees are a species-rich and threatened animal group in modern forestry and agriculture in southern Sweden. New research from the University of Gothenburg shows that management with conservation thinning can be an effective way to promote these beetles in the long term.
Based on the genetic and morphological data, researchers were able to say that the Blotched Rat Snake (Elaphe sauromates) is actually comprised of two different species and includes a cryptic species that has been named after the old kingdom of Urartu.
The mutual dependencies of many plant species and their pollinators mean that the negative effects of climate change are exacerbated. As UZH researchers show, the total number of species threatened with extinction is therefore considerably higher than predicted in previous models.
(Stockholm University) An international type model of a university alliance will be established between Karolinska Institutet, KTH and Stockholm University. The aim is to strengthen the development of the Stockholm region and to highlight the internationally distinguished research and education environment that the three universities constitute together. An agreement will be signed on May 27, 2019 that will make it easier for the three universities in the Swedish capital to enter into joint collaborations with universities around the world.
(Regenstrief Institute) Regenstrief Institute investigator Noll Campbell has received a five-year $3.3 million award from NIA to conduct first cause and effect trial to determine if stopping anticholinergics results in sustained improvements in cognition. If study finds that reducing or discontinuing use of these commonly prescribed drugs among current users improves brain health without adversely impacting other medical conditions, study will have identified a way to decrease an estimated 50,000 new cases of dementia annually in US.
(Johannes Gutenberg Universitaet Mainz) The German Research Foundation (DFG) has approved the extension of funding of the Transregional Collaborative Research Center "Waves to Weather" starting in July 2019. During this second funding period, the CRC/TRR 165 will be receiving some EUR 10 million. The consortium aims to understand and determine the limits of predictability of weather, which is challenging due to the chaotic nature of the atmosphere.
(University of Montreal) In his lab, UdeM professor Alexis Vallée-Bélisle is busy perfecting a biosensor that patients with kidney disease, heart disease or other chronic illnesses can use without leaving home.
The study analyzed the bone mineral density of 173 adults between 35 and 50 years old. Participants were scanned at the femoral hip and lumbar spine, using dual-energy X-ray absorptiometry, which is proven to be precise, while exposing patients to a minimal dose of radiation. Findings indicate more middle-aged adults should be scanned to understand their risk and establish a baseline for monitoring.
Supernovae bombarded Earth with cosmic energy starting as many as 8 million years ago, with a peak some 2.6 million years ago, initiating an avalanche of electrons in the lower atmosphere and setting off a chain of events that feasibly ended with bipedal hominins.
