Shopping online or locally - an individual choice

Apr 26 2021 - 00:04
Boundary conditions of shopping, such as shipping costs or travel time, are of central importance for individual store choices. Assessment of purchasing security, environmental protection aspects, and work conditions also come into play when deciding between online and local. This is found by a microeconometrical, representative study at Karlsruhe Institute of Technology (KIT) funded by the German Research Foundation. Some of its results are now reported in Papers in Applied Geography and Raumforschung und Raumordnung.

Cell adaptation in critically ill could be difference between life and death

Apr 26 2021 - 00:04
The study showed that the cells of people who survived critical illness (ie two or more organs failing) produced energy in a different way to those who did not survive. The behaviour of critically ill cells looks similar to how cells adapt to limited oxygen levels (hypoxia). The work took place before the COVID-19 pandemic, but findings are relevant to patients on ventilators experiencing low oxygen levels or multiple organ failure.

Study looked at how nurses view touch as a form of care

Apr 26 2021 - 00:04
Touching patients while providing care is an important and unavoidable aspect of the nursing profession. Nurses can also transform touch into a useful therapeutic tool to improve patients'-- and their own--wellbeing. That is the topic of a study, "'Permission to Touch': Nurses' Perspectives of Interpersonal Contact during Patient Care," published in the Western Journal of Nursing Research. Through focus groups and interviews, participants said they found touch and massage helpful when providing patient care.

Pain patients and healthcare providers want CDC opioid guideline revoked

Apr 26 2021 - 00:04
The opioid prescribing guideline released by the Centers for Disease Control and Prevention in 2016 has failed to reduce addiction and overdoses, significantly worsened the quality of pain care in the United States and should be revoked, according to a large new survey of patients and healthcare providers.

Football Fitness gives an important boost to health in women treated for breast cancer

Apr 26 2021 - 00:04
The University of Southern Denmark (SDU), Rigshospitalet and the University of Copenhagen have come together to study the effects of Football Fitness on various health parameters and self-rated health following treatment for breast cancer.The study concludes, that Football Fitness strengthens bones and muscles as well as improving balance in women treated for breast cancer. This in turn reduces the risk of various established long-term consequences of the medical treatment the women have undergone.

Genome sequencing delivers hope and warning for the survival of the Sumatran rhinoceros

Apr 26 2021 - 00:04
A study led by researchers at the Centre for Palaeogenetics in Stockholm shows that the last remaining populations of the Sumatran rhinoceros display surprisingly low levels of inbreeding. The genomes from 21 modern and historical rhinoceros' specimens were sequenced to investigate the genetic health in rhinos living today and ones that recently became extinct. With less than 100 individuals remaining, the Sumatran rhinoceros is one of the most endangered mammal species in the world.

Close monitoring for heart risk needed if breast, prostate cancer treatment includes hormones

Apr 26 2021 - 00:04
Patients with breast and prostate cancers who are treated with hormonal therapies have an increased risk of heart attack and/or stroke as they age.The increased likelihood of a heart attack or stroke is greater in patients who already have two or more cardiovascular risk factors such as high blood pressure, high cholesterol, obesity, smoking or a family history of heart disease or stroke.The longer the duration of hormonal therapy, the higher the risk of cardiovascular disease.

Study examines association between lifestyle patterns and BMI in early childhood

Apr 26 2021 - 00:04
A new Australian study reveals that changes in lifestyle patterns were longitudinally associated with concurrent changes in body mass index (BMI) z scores, and maternal pre-pregnancy BMI, maternal dietary patterns and television viewing time are significant determinants, according to a paper published online in Obesity, The Obesity Society's (TOS) flagship journal. This is the first study that used multi-trajectory modeling to examine the longitudinal relationship between concurrent changes in lifestyle patterns and BMI z scores in early childhood.

More than half of generation Z gay, bisexual teenage boys report being out to parents

Apr 26 2021 - 00:04
A majority of gay and bisexual Generation Z teenage boys report being out to their parents, part of an uptick in coming out among young people that researchers have noted in recent decades, according to research published by the American Psychological Association. However, stigma and religious beliefs still prevent some young people from disclosing their sexual identity.

Chinese hazelnut: The newest piece in the hazelnut genome puzzle

Apr 25 2021 - 00:04
Hazelnut is widely grown for its rich oleic acid content and flavor. However, owing to the unavailability of high-quality genetic resources for hazelnut, crop improvement has remained a significant challenge. A new study published in Horticulture Research presents a high-quality whole genome analysis of Chinese hazelnut, along with identification of several genes underlying economically important traits like oil content and disease resistance. These findings can lead to improvements in hazelnut yield worldwide.

Biophysicists found an Achilles heel of a cancerogenic virus

Apr 25 2021 - 00:04
The team identified a fundamental pattern in the work of the human proteins and determined the structure of their complex with a functional fragment of the papillomavirus oncoprotein. Using these data, the team suggested a way to affect the stability of the studied protein complex, which could be further developed into a therapeutic approach against papillomavirus infections.

In-cell nano-3D printer: Synthesizing stable filaments from in-cell protein crystals

Apr 25 2021 - 00:04
Scientists at Tokyo Institute of Technology (Tokyo Tech) have pioneered a novel method for producing supramolecular protein assemblies from protein crystals. Their approach involves strategically introducing mutations in a protein monomer to create disulfide bonds (S-S) between the building blocks of protein crystals at very specific sites. After isolating the protein crystals from the cells and dissolving them, these bonds create uniform, stable filaments. Such protein assemblies could find applications in molecular storage, drug delivery, and catalysis.
