Everyday products carry environmental chemicals that may be making us fat by interfering with our hormones, according to research presented in Barcelona at the European Society of Endocrinology annual meeting, ECE 2018. Following recommendations on how to avoid these chemicals could help minimise exposure and potentially reduce the risk of obesity and its complications.
MAYWOOD, IL - A Loyola Medicine study has found that new ultrasound guidelines can reliably identify pediatric patients who should be biopsied for thyroid cancer.
The study by radiologist Jennifer Lim-Dunham, MD, and colleagues was presented May 18 during the Society for Pediatric Radiology's annual meeting in Nashville.
Thyroid cancer is a common cause of cancer in teenagers, and the incidence is increasing for reasons that are unclear. Adolescents have a 10-fold greater incidence than younger children, and the disease is five times more common in girls than boys.
PHILADELPHIA - Dogs born June through August are at higher risk of heart disease than those born other months, rising in July to 74 percent higher risk, according to a study published this week in Scientific Reports from researchers at the Perelman School of Medicine at the University of Pennsylvania. A correlation to outdoor air pollution may be the culprit.
The birth month difference in risk was marginal among breeds that are genetically predisposed to the disease, suggesting that heart disease acquired later in life may be birth season dependent among all dog breeds.
Turning genes on and off is an intricate process involving communication between many different types of proteins that interact with DNA.
Hospitalized patients who experience acute kidney injury face a 44 percent greater risk of heart failure during their first year after leaving the hospital, according to new Kaiser Permanente research published today in the Clinical Journal of the American Society of Nephrology.
Most people are familiar with A, B, AB and O blood types, but there are hundreds of additional blood group "antigens" on red blood cells - substances that can trigger the body's immune response - that differ from person to person. Each year, up to 16 deaths reported to the Federal Drug Administration are attributed to mismatches in red blood cell antigens that are not related to differences in A, B and O blood groups. Currently, no method is available that can determine all blood antigens.
An automated system that uses robots has been designed to rapidly produce human mini-organs derived from stem cells. Researchers at the University of Washington School of Medicine in Seattle developed the new system.
The advance promises to greatly expand the use of mini-organs in basic research and drug discovery, according to Benjamin Freedman, assistant professor of medicine, Division of Nephrology, at the UW School of Medicine, who led the research effort.
PITTSBURGH, May 17, 2018 - Smoking tobacco from a waterpipe, also known as a hookah, accounted for over half of the tobacco smoke volume consumed by young adult hookah and cigarette smokers in the U.S., a new University of Pittsburgh School of Medicine analysis discovered.
Montreal, May 17, 2018 - A new study led by a team at the Research Institute of the MUHC (RI-MUHC) in Montreal has revealed that pregnant women with rheumatoid arthritis (RA) may be able to use certain RA drugs without possible increased health risks to their unborn babies. The research findings are published today in the journal Arthritis & Rheumatology.
Lenses and mirrors with freeform surfaces enable designers to focus light within optical devices that are lighter, more compact, and more effective than ever before.
But until now, determining which freeform surfaces will work best - if at all - in a given configuration of mirrors and lenses has been a time-consuming and often expensive process of trial and error.
It doesn't have to be that way anymore.
Boulder, Colo., USA: Research undertaken in South Africa's Kruger National Park (KNP) has shown that some of the world's most sensitive and valuable riverine habitats are being destroyed due to an increasing frequency of cyclone-driven extreme floods.
Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have successfully generated controlled electron pulses in the attosecond range. They used optical travelling waves that are formed by laser pulses of varying wavelengths. The movements of electrons in atoms were revealed using attosecond free-electron pulses. The findings of the researchers from Erlangen have been published in the acclaimed journal Physical Review Letters (DOI: 10.1103/PhysRevLett.120.103203).
Researchers in Germany have discovered that colon cancers are often resistant to existing drug treatments because they are composed of two different cell types that can replace each other when one cell type is killed. The study, which will be published May 16 in the Journal of Experimental Medicine, suggests that combination therapies targeting both cell types at once may be more effective at treating colorectal cancer, the third highest cause of cancer-related death in the United States.
The scientists of the Lobachevsky University and the Institute of Low Temperatures and Structural Research in Wroclaw (Poland) conducted unique studies of oscillation properties using modern methods of optical spectroscopy.
COLUMBUS, Ohio - Many studies have shown that both minority and women scientists face disadvantages in reaching the highest levels of their careers.
So it would make sense that minority women would face a "double bind" that would particularly disadvantage them.
But a new study using a massive database of scientific articles suggests that minority women actually face what might be called a "one-and-a-half bind." They are still worse off than other groups, but their disadvantage is less than the disadvantage of being black or Hispanic plus the disadvantage of being a woman.
