Analyzing the impact of ovulation-inducing agents on the quality of embryo

Analyzing the impact of ovulation-inducing agents on the quality of embryo
2024-04-22
Low birth rates have become a serious problem in many developed countries throughout the world, with Japan being a prime example. In Japan particularly, aging and stress have led to a massive rise in infertility, which now affects one in every 4.4 couples. To find a workaround this condition, many couples have now turned to assisted reproduction technologies (ARTs) and in vitro fertilization (IVF) for conception. However, even though ARTs and IVF methods are well-established and have been widely used for over four decades, birth rates post IVF in Japan are still critically low, peaking at a meager 10.2%. One of the reasons ...

In psychedelic therapy, clinician-patient bond may matter most

2024-04-22
COLUMBUS, Ohio – Drug effects have dominated the national conversation about psychedelics for medical treatment, but a new study suggests that when it comes to reducing depression with psychedelic-assisted therapy, what matters most is a strong relationship between the therapist and study participant. Researchers analyzed data from a 2021 clinical trial that found psilocybin (magic mushrooms) combined with psychotherapy in adults was effective at treating major depressive disorder. Data included depression outcomes and participant reports about their experiences ...

Family learning environments in Scandinavia: dimensions, types and socioeconomic profiles

Family learning environments in Scandinavia: dimensions, types and socioeconomic profiles
2024-04-22
Do children have regular bedtimes and do parents enforce strict screen time policies? And do parents take their children to museums so that they can learn from an early age? Or is everyday life more about having fun together, without clear rules and any ambition to ‘develop’ children in any particular way? Family life can be lived in many different ways, and what children bring with them from the home environment has a substantial impact on their opportunities and development later in life. A new study from the Department of Sociology, University of Copenhagen, and VIVE - The Danish Center for Social Science Research ...

People think 'old age' starts later than it used to, study finds

2024-04-22
Middle-aged and older adults believe that old age begins later in life than their peers did decades ago, according to a study published by the American Psychological Association. “Life expectancy has increased, which might contribute to a later perceived onset of old age. Also, some aspects of health have improved over time, so that people of a certain age who were regarded as old in the past may no longer be considered old nowadays,” said study author Markus Wettstein, PhD, of Humboldt University in Berlin, Germany.  However, the study, which was published in the journal Psychology and Aging, also found evidence that the trend of later perceived old age has slowed ...

Afib more common and dangerous in younger people than previously thought

2024-04-22
PITTSBURGH, April 22, 2024 – Atrial fibrillation (Afib), a common type of arrhythmia that is on the rise in people under the age of 65, is more dangerous in this increasingly younger population than previously thought, according to a new study published today in Circulation Arrhythmia and Electrophysiology and authored by physician-scientists at the UPMC Heart and Vascular Institute. The study, which is among the first to examine a large group of Afib patients younger than 65 in the U.S., found that these younger patients were more likely to be hospitalized for heart failure, stroke or heart ...

Same species, different sizes: rare evolution in action spotted in island bats

Same species, different sizes: rare evolution in action spotted in island bats
2024-04-22
A University of Melbourne researcher has spotted a rare evolutionary phenomenon happening rapidly in real time in bats living in the Solomon Islands. Dr Tyrone Lavery reports in a paper published in Evolution that two groups of leaf-nosed bats with vastly different body sizes that were thought to be separate species are an example of a rare type of parallel evolution. Parallel evolution is when different populations living in similar environments evolve similar features independently. The smaller bat, Hipposideros diadema, is found across its six main islands and many smaller islands. It is ...

New technology uncovers mechanism affecting generation of new COVID variants

2024-04-22
The SARS-CoV-2 virus that causes COVID has the unsettling ability of often generating variants of itself. Other viruses also mutate, but as SARS-CoV-2 quickly spread throughout the entire human population during the pandemic, killing millions, the virus’ dynamic evolution posed a serious problem: it repeatedly challenged our bodies’ immune response fighting the virus and hindered the process of getting updated vaccines ready. Understanding the genetic mechanism fueling SARS-CoV-2’s ability to generate variants can go a long way in keeping COVID at bay. In this study published in Nature Microbiology, researchers at Baylor College of Medicine and collaborating institutions developed ...

An international team led by researchers at the University of Toronto has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the cell cycle, which required a combination of deep learning and high-throughput microscopy. The team applied two convolutional neural networks, or algorithms, called DeepLoc and CycleNet, to analyze images of millions of live yeast cells. The result was a comprehensive map identifying where proteins are located and how they move and change in abundance ...

Pressure in the womb may influence facial development

2024-04-22
Physical cues in the womb, and not just genetics, influence the normal development of neural crest cells, the embryonic stem cells that form facial features, finds a new study led by UCL researchers. The study published in Nature Cell Biology found that an increase in hydrostatic pressure sensed by the embryo can hinder the healthy development of facial features in mouse and frog embryos and in human embryoids (cell structures grown in the lab from human stem cells), suggesting that differences in pressure might affect the risk of facial malformations. The ...

2024-04-22
Feedback loop that is melting ice shelves in West Antarctica revealed New research has uncovered a feedback loop that may be accelerating the melting of the floating portions of the West Antarctic Ice Sheet, pushing up global sea levels. The study, published in Science Advances, sheds new light on the mechanisms driving the melting of ice shelves beneath the surface of the ocean, which have been unclear until now. The West Antarctic Ice Sheet has been losing mass in recent decades, contributing to global sea level rise. If it were to melt entirely, global sea levels would rise by around five meters. It’s known that Circumpolar Deep Water (CDW), ...

How does aspirin help prevent colorectal cancer development and progression?

2024-04-22
Long-term daily use of aspirin can help to prevent the development and progression of colorectal cancer, but the mechanisms involved have been unclear. New research has revealed that aspirin may exert these protective effects by boosting certain aspects of the body’s immune response against cancer cells. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society. To investigate the effects of aspirin (a nonsteroidal anti-inflammatory drug) on colorectal cancer, investigators in Italy obtained tissue samples from 238 patients who underwent surgery for colorectal cancer in 2015–2019, 12% of whom were aspirin ...

3 in 5 parents play short order cook for young children who don’t like family meal
2024-04-22
While most parents of preschool and elementary aged children strive to give their children a balanced, nutritional diet, some of their strategies to promote healthy eating may backfire, a national poll suggests. A top example from the report: Three in five parents customize meals if their child doesn’t like what everyone else is eating. Meanwhile, one in eight parents require children to eat everything on their plate, according to the University of Michigan Health C.S. Mott Children’s Hospital National Poll on Children’s Health. And while just one in three believe the standard American diet is healthy for kids, few have tried alternative, potentially more nutritional ...

Japan’s premodern concept of nature at root of distinctive mindset in early childhood education

Japan’s premodern concept of nature at root of distinctive mindset in early childhood education
2024-04-22
Osaka, Japan — Observers of Japanese early childhood education and care have pointed to the mindset of educators watching over and waiting on preschoolers as being an intriguing tendency. This mimamoru approach has its roots in a premodern concept of nature, according to Professor Yosuke Hirota at the Graduate School of Literature and Human Sciences of Osaka Metropolitan University. Professor Hirota looked into the works of Sozo Kurahashi (1882-1955) and Kitaro Nishida (1870-1945) to see how this concept of nature from the past made its way into education in the present day. Kurahashi’s writing on ...

First Nations patients leave ED without completing treatment more than comparable non–First Nations patients

2024-04-22
First Nations patients in Alberta leave emergency departments (EDs) without completing treatment more often than comparable non–First Nations patients, due in part to anti-Indigenous racism expressed by providers, found new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.231019. Higher proportions of incomplete ED care for First Nations patients compared with non–First Nations patients occurred even in cases of serious diagnosis, and were found across all parts of Alberta.
