Are there sex-based differences in brain development during early childhood?

2023-03-22
(Press-News.org) New research published in Human Brain Mapping reveals sex differences and developmental changes in the brain’s white matter—which provides communication between different parts of the brain—in healthy, typically developing infants and 5-year-olds.

The results, which highlighted sexual dimorphism in brain structure during development with significant detectable differences in multiple regions at the age of 5 years, agree with prior studies showing earlier brain development in females.

Also, changes in white matter asymmetry patterns occurred during early childhood, and in 5-year-olds the pattern already resembled adult-like patterns.

“We observed sex differences in white matter microstructure of 5-year-olds that may, in light of previous literature, be a transient feature during brain development,” said corresponding author Venla Kumpulainen, MSc, MD, of the University of Turku, in Finland. “More investigations are required to examine whether these findings associate with developmental cognitive and emotional differences between girls and boys.”

Boosting the effects of a particular microRNA may benefit patients with cervical cancer

2023-03-22
Dysregulation of microRNAs, which are molecules involved in controlling gene expression, can promote tumor formation and progression. A study in The FASEB Journal found that the miR-145 microRNA can suppress the growth of cervical cancer cells. miR-145 was expressed at lower than normal levels in human cervical cancer cells, and lower levels correlated with more advanced clinical stages of cervical cancer in patients.  Experiments in cells and mice revealed the mechanisms behind miR-145 effects and pointed to potential targets that could be ...

Changing temperatures increase pesticide risk to bees

Changing temperatures increase pesticide risk to bees
2023-03-22
Temperature influences how badly pesticides affect bees’ behaviour, suggesting uncertain impacts under climate change, according to a new study. The findings indicate that future extreme temperature events under climate change could increase the impact of pesticides on bee populations and their pollination services. Certain pesticides, particularly a class called neonicotinoids, are known to impact bees and other important insects, and are thought to be contributing to population declines. However, bees’ reported responses to this threat across the world often seem to vary, suggesting other interacting factors ...

Research reveals substantial human cost of international COVID-19 travel and border restrictions

2023-03-22
Findings paint a bleak picture of little or no financial and health support from governments for their citizens stuck overseas. At least two-thirds of those stranded aboard experienced financial distress and moderate-to-severe levels of depression—a rate that is substantially higher than the general population and health care professionals in the pandemic. **Note: the release below is a special early release from the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2023, Copenhagen, 15-18 April).

New animal welfare scoring system could enable better-informed food and farming choices

New animal welfare scoring system could enable better-informed food and farming choices
2023-03-22
Cambridge University scientists have come up with a system of measuring animal welfare that enables reliable comparison across different types of pig farming. This means that animal welfare can now, for the first time, be properly considered alongside other impacts of farming to help identify which farming systems are best. This is vital for improving animal welfare in livestock production, at a time when demand for meat is rising globally and the way animals are farmed is changing - with concerns about the welfare of intensive and indoor systems. Animal welfare assessments could also enable consumers to be better informed when choosing what to eat. Britain ...

Science journals update guidelines after study highlights incomplete reporting of research

2023-03-22
Several scientific journals have amended their submission guidelines after an analysis identified numerous research studies that had been published with crucial information missing. The finding emerged from an analysis by academics at the University of Cambridge, which reviewed reports from trials evaluating new school-based programmes to increase the amount of children’s physical exercise. It found that 98% of these reports left out key details about how teachers had been trained to deliver the interventions. The trial reports ...

Study shows ‘obesity paradox’ does not exist: waist-to-height ratio is a better indicator of outcomes in patients with heart failure than BMI

2023-03-22
New research has debunked the idea that there is an “obesity paradox”, whereby patients with heart failure who are overweight or obese are thought to be less likely to end up in hospital or die than people of normal weight.   The study, which is published in the European Heart Journal [1] today (Wednesday), shows that if doctors measure the ratio of waist to height of their patients, rather than looking at their body mass index (BMI), the supposed survival advantage for people with a BMI of 25kg/m2 or more disappears.   The “obesity paradox” relates to counter-intuitive findings suggesting that, although people are at greater risk of developing ...

The devil is in the details: Re-imagining fertilizer precursor synthesis

The devil is in the details: Re-imagining fertilizer precursor synthesis
2023-03-22
Osaka, Japan – The Haber–Bosch reaction helps feed the world by converting nitrogen into ammonia, a fertilizer precursor. However, its carbon footprint is huge: this one reaction is the source of nearly 2% of global carbon emissions. Now, in a study recently published in ACS Energy Letters, researchers from Osaka University have helped re-imagine this reaction to improve the sustainability of the chemical industry. Replacing the Haber–Bosch reaction with a more sustainable alternative has been an active area of research for many years. These efforts have led to a globally well-established electrochemical reaction for ammonia ...

Unmasking the secret of broadly neutralising COVID-19 therapeutic antibodies

2023-03-22
The rapid evolution and emergence of new SARS-CoV-2 variants, such as the Omicron variant, renders it highly capable of evading the host immunity. At the same time, vaccines based on original wild-type strain of SARS CoV-2 shows reduced protection against newer variants, particularly for the Omicron variant. This results in break-through infections among those vaccinated and highly infectious among non-vaccinated individuals. Thus, it remains uncertain whether new emerging variants of the COVID-19 disease can escape the protective immune response ...
