Quercetin is a natural occurring flavonoid. Quercetin exerts a direct pro-apoptotic effect on tumor cells by blocking the growth of several cancer cell lines at different phases of the cell cycle. Quercetin derivatives have attracted considerable attention for their cytotoxicity against human cancer cell lines. This project was aimed for pharmacophore mapping of NSCLC cells by focusing on finding the structure of the receptor. The compounds were of natural origin, which are known to act on the NSCLC protein and there are notable references of such compounds in scholarly literature.

At the beginning of August, the European Medicines Agency (EMA) published a report on a pilot project of a new accelerated path for drug approval (adaptive pathways). In this approval procedure, for a highly restricted population drugs are to be launched on the market faster based on less evidence. Further data on effectiveness, safety, and benefit for broader use are only to be generated after drug approval within everyday health care - as so-called real world data.
Intermittent parathyroid hormone treatment (iPTH) and mechanical loading through exercise have both been shown to stimulate bone formation. These osteoanabolic stimuli are partially mediated by G protein-coupled receptors. Previous studies have suggested that enhanced signalling through the Gαq/11 pathway inhibits the bone-building actions of PTH, however the influence of enhanced Gαq/11 pathway on exercise has not been reported in vivo.
Ocean acidification, rising temperatures, eutrophication and loss of oxygen: Life in the oceans has to cope with a variety of factors. How will plants and animals react when global climate change alters their environment? Laboratory and field experiments, observations at naturally extreme habitats and modelling approaches help researchers to evaluate the reactions of the ecosystem ocean.
A Japanese research group has determined the crystal structure of the JUNO protein, an egg surface protein essential for fertilization. These structure-based mutational analyses elucidated a mechanism of the interaction between egg (JUNO protein) and sperm (IZUMO1) on a molecular level. These studies will provide a framework toward an understanding of the fertilization mechanism.
In the journal, Nature Communications, a team of Danish researchers reports that they have developed a new class of artificial proteins. In the long term, the results could lead to better treatment of cancer and diabetes.
Nature has created a host of proteins, which come in many forms, and which have many functions in our body. They are the body's principal, and hardest working building blocks. For example, some of them provide our muscles with strength; while others make sure that our cells receive messages.
CINCINNATI - Patients with sickle cell anemia (SCA) develop heart complications and nearly a quarter die a sudden death. Now, researchers have linked malfunctioning molecular pathways to specific heart anomalies in SCA that result from progressive fibrosis and result in sudden death.
The luxury goods market for the ultra rich encompasses jewelry, cars, clothes, tableware, ornaments and much more. If luxury hotels, travel and other services are included alongside retail sales, this sector amounted to $1 trillion dollars in 2015. As such, there is a vast grey market for goods that mimic the priciest brands but sell to people who are less well off. Ian Phau and Min Teah of Curtin Business School, at Curtin University in Perth, Western Australia, explain how, "brand familiarity is postulated to be a mediator between perception of luxury and product evaluation.
Boston, MA--A new study from Brigham and Women's Hospital utilized claims data from more than 630,000 patients living in the state of California and found no significant differences in post-operative complications or mortality between African American patients and White patients who were treated in a universally insured military health system.
(BOSTON) -- When in dysfunction, the vascular endothelium -- the tissue that lines the blood vessels throughout our body's entire circulatory system -- plays a big role in the development of many human diseases, including diabetes, stroke, heart disease, viral infections and cancer. This is because endothelial cells are sensitive to blood flow and also interact with blood cells through molecules on their surface, so that blood coagulation and platelet function are modulated. In normal 'hemostasis', the endothelium prevents deadly blood loss and clot formation.
People who ate a diet high in nuts and legumes, low-fat dairy, whole grains, fruits, and vegetables and low in red and processed meat, sugar-sweetened beverages and sodium were at a significantly lower risk of developing chronic kidney disease over the course of more than two decades, new Johns Hopkins Bloomberg School of Public Health research suggests.
The White House wants to cut U.S. greenhouse gas (GHG) emissions by 80 percent by 2050, but the goal raises questions about one of the greatest sources of those pollutants, light-duty vehicles (LDVs). The Energy Department's National Renewable Energy Laboratory (NREL) has taken a close look at what specific combination of measures national experts have determined is needed to slash LDV emissions from 1,514 million metric tons (MMTs) to 303 MMTs of carbon dioxide (CO2) per year and meet this larger emissions-reduction goal.
ANN ARBOR, Mich. - As a childhood obesity expert and black woman, Susan Woolford, M.D., MPH, knows that some girls and women in the black community feel as if they have to choose between their health and their hair.
Gym class, school sports and other exercise routines bring important health benefits. But sweating also means potentially bad hair days and ruining time-consuming and costly hairstyles.
The prevalence of preterm birth - the birth of an infant prior to 37 weeks of pregnancy - is a significant health problem that has increased over the past two decades. According to the Centers for Disease Control and Prevention (CDC), preterm birth affects nearly 500,000 babies each year, or one of every eight born in the U.S. While medical care has improved survival rates for preterm infants, questions remain about ways to positively impact the neurodevelopmental outcomes of preterm infants.
HOUSTON - (Aug. 9, 2016) - Breast cancer tumors are complex and dynamic. They comprise a population of continuously dividing cells that carry different genetic mutations.
