Newly released study results present a strong case for lung cancer screening in New Zealand - particularly for Māori whose mortality rates are between three and four times higher than other ethnic groups.
Around 450 Māori are diagnosed with lung cancer each year and approximately 300 die from it.
First described in the 13th century in Russia, clubroot has been affecting worldwide brassica production, including canola, broccoli, and black mustard, since. Clubroot is so tenacious because the casual pathogen produces resting spores that can survive in infected soil for decades, surviving harsh environments like cold winters and hot summers. It is also easily transferable from field to field when farmers share equipment.
During the process of natural selection and evolution, many animals and plants, such as snakes, scorpions and sea anemones, have acquired the ability to produce venom, which is regarded as their strong weapon for self-defense and predation. Toxic peptides extracted from venom can specifically plays a key role in Acid-Sensing Ion Channel (ASIC), cell membrane surface receptors and proteins intensively involved in life activities.
New research is revealing how genetic differences in the fat in men's and women's bodies affect the diseases each sex is likely to get.
University of Virginia researchers Mete Civelek, PhD, Warren Anderson, PhD, and their collaborators have determined that differences in fat storage and formation in men and women strongly affect the activity of 162 different genes found in fat tissue. Further, 13 of the genes come in variants that have different effects in men and women.
CORVALLIS, Ore. - An Oregon State University study has identified four new species of parasitic, cockroach-killing ensign wasps that became encased in tree resin 25 million years ago and were preserved as the resin fossilized into amber.
What causes quasiparticle death?
In large systems of interacting particles in quantum mechanics, an intriguing phenomenon often emerges: groups of particles begin to behave like single particles. Physicists refer to such groups of particles as quasiparticles.
Understanding the properties of quasiparticles may be key to comprehending, and eventually controlling, technologically important quantum effects like superconductivity and superfluidity.
CLEVELAND, Ohio (September 28, 2020)--Although many women manage menopause symptoms with hormone therapy, increasing numbers of women are considering nonhormone options. Dr. Susan Reed from the University of Washington School of Medicine is a featured speaker during the 2020 Pre-Meeting Symposium of The North American Menopause Society (NAMS) and will discuss the latest advances in nonhormone hot flash management. One of the more promising drug developments targets the KNDy neuron complex.
CLEVELAND, Ohio (September 28, 2020)--Hormone therapy remains the best proven method for managing menopause symptoms such as hot flashes. Research continues, however, in the area to identify novel approaches to estrogen therapy that minimize any associated risks. Dr. Hugh Taylor from Yale School of Medicine will discuss some of the latest developments, including fetal estrogens, during the 2020 Pre-Meeting Symposium of The North American Menopause Society (NAMS).
CLEVELAND, Ohio (September 28, 2020)--As legislation relaxes regarding cannabis, it is being used to manage numerous chronic health conditions and mood symptoms. A new study indicates that a growing number of women are either using cannabis or want to use it for the management of bothersome menopause symptoms. Study results will be presented during the 2020 Virtual Annual Meeting of The North American Menopause Society (NAMS), which opens on September 28.
CLEVELAND, Ohio (September 28, 2020)--Women often complain of being more forgetful during the transition from premenopause to perimenopause to postmenopause. Such declines in memory after menopause appear independent of chronologic age. A new study sought to identify whether mitochondrial function might be a determinant of cognition during early postmenopause. Study results will be presented during the 2020 Virtual Annual Meeting of The North American Menopause Society (NAMS), opening on September 28.
Socioeconomic inequalities in premature deaths in Canada have increased over the last 25 years, according to new research published in CMAJ (Canadian Medical Association Journal.
With the summer heat becoming increasingly unbearable and prolonged over the years due to climate change, the cooling load in the summertime has also been on the rise. Insulation is currently the primary solution for blocking heat from entering a building, but by applying an additional material that can delay heat penetration, it can suppress the indoor temperature from rising and in turn lower the cooling load of the building.
Researchers have shown that over the past two thousand years, volcanoes have played a larger role in natural temperature variability than previously thought, and their climatic effects may have contributed to past societal and economic change.
Scientists from the University of Sheffield have found that although male and female birds have an almost identical set of genes, they function differently in each sex through a mechanism called alternative splicing.
What The Study Did: Researchers investigated the association between race and COVID-19 after accounting for age, sex, socioeconomic status and comorbidities.
Authors: L. Silvia Muñoz-Price, M.D., Ph.D., of the Medical College of Wisconsin in Milwaukee, is the corresponding author.
