Genes shed light on why men and women experience different depression symptoms

2023-03-17
(Press-News.org) Depression is widely reported to be more common in women than in men, with women twice as likely to receive a diagnosis than men. A new sex-specific study from McGill University has found that there are differences between male and female genes and how they relate to depression. In a study of more than 270,000 individuals, the researchers found that sex-specific prediction methods were more accurate in forecasting an individual’s genetic risk of developing depression than prediction methods that did not specify sex. The researchers found 11 areas of DNA that were linked to depression in females, and only one area in males. They also found that depression was specifically linked to metabolic diseases in females, an important aspect to consider when treating women with depression. Despite the biological processes involved in depression being similar in males and females, researchers found that different genes were involved for each sex. This information can be useful to identify future sex-specific treatments for depression.  "This is the first study to describe sex-specific genetic variants associated with depression, which is a very prevalent disease in both males and females. These findings are important to inform the development of specific therapies that will benefit both men and women while accounting for their differences,” says Dr. Patricia Pelufo Silveira, lead author and Associate Professor in the Department of Psychiatry. “In the clinic, the presentation of depression is very different for men and women, as well as their response to treatment, but we have very little understanding of why this happens at the moment.”

Breaking barriers in hepatitis C diagnosis and treatment for populations at risk

Breaking barriers in hepatitis C diagnosis and treatment for populations at risk
2023-03-17
A study with people who inject drugs evaluated a minimally invasive test based on dried blood spots (DBS) for the monitoring of hepatitis C virus (HCV) infection. The use of DBS samples for HCV RNA detection and genotyping was shown to effectively assess cure after treatment and to differentiate between reinfection and treatment failure. The results support the viability of decentralizing treatment and post-treatment monitoring for people who inject drugs, who frequently face challenges accessing the healthcare system. The study, which has been published in the Journal of Medical Virology, was carried out as part of a project with support from the "Conquering ...

Carbon nanotube films as ultrasensitive photodetectors: progress and challenges

Carbon nanotube films as ultrasensitive photodetectors: progress and challenges
2023-03-17
Semiconducting single-walled carbon nanotubes (s-SWCNTs) are being used to develop a third generation of optimized shortwave infrared photodetectors that will improve pixel size, weight, power consumption, performance and cost over photodetectors made from traditional materials.   Ultrasensitive shortwave infrared photodetectors, which detect a subset of shortwave infrared light wavelengths outside of the visual spectrum, have many potential applications, including night surveillance, navigation during poor weather conditions, fiber optic communications and semiconductor quality control.  Shortwave ...

Mountain forests are being lost at an accelerating rate, putting biodiversity at risk

Mountain forests are being lost at an accelerating rate, putting biodiversity at risk
2023-03-17
More than 85% of the world’s bird, mammal, and amphibian species live in mountains,  particularly in forest habitats, but researchers report in the journal One Earth on March 17 that these forests are disappearing at an accelerating rate. Globally, we have lost 78.1 million hectares (7.1%) of mountain forest since 2000—an area larger than the size of Texas. Much of the loss occurred in tropical biodiversity hotspots, putting increasing pressure on threatened species. Though their rugged location once protected mountain forests from deforestation, they have been increasingly exploited since the turn of ...

River deltas: Valuable and under threat

2023-03-17
The livelihoods of millions of people who live in river deltas, among the world’s most productive lands, are at risk. Created where large rivers meet the ocean and deposit their natural sediment load, river deltas are often just a few meters above sea level. And while they make up less than 0.5 % of the world’s land area, river deltas contribute more than 4 % of the global GDP, 3% of global crop production, and are home to 5.5 % of the world’s population. All of these values are highly vulnerable to imminent global environmental change, according to a new Stanford University-led study. “It is often not rising seas, but sinking land due to human activities that ...

Few Medicaid-participating primary care physicians providing longer-acting birth control methods

2023-03-17
WASHINGTON (March 17, 2023)— Medicaid beneficiaries face barriers in accessing medical care – and that includes contraceptive care. A new study finds that despite birth control being an essential health service, all primary care physicians that see them may not be offering Medicaid patients some of the most effective, longer-acting birth control methods. While nearly half (48%) of primary care physicians who treat Medicaid patients provided prescription contraception like the birth control pill, only 10% provided longer-acting methods like IUDs ...

Association of household opioid availability with opioid overdose

2023-03-17
About The Study: In this study of Oregon residents in households of at least two members, the findings suggest that household prescription availability is associated with increased odds of opioid overdose for others in the household, even if they do not have their own opioid prescription. These findings underscore the importance of educating patients about proper opioid disposal and the risks of household opioids.  Authors: Michelle A. Hendricks, Ph.D., of Comagine Health in Portland, Oregon, is the corresponding ...

Association of warm or cold air temperatures with lung function in young infants

2023-03-17
About The Study: Long-term heat and cold exposure from the second trimester until four weeks after birth was associated with newborn lung volumes, especially among female newborns, in this study of 343 mother-child pairs. The findings suggest an association between ambient temperature and newborns’ respiratory systems and underlines the vulnerability of pregnant women and their future children to climate change.  Authors: Ariane Guilbert, M.Sc., and Johanna Lepeule, Ph.D., of Universite Grenoble Alpes in La Tronche, France, are the corresponding authors.  To access the embargoed study: Visit our For The Media website at this link https://media.jamanetwork.com/  (doi:10.1001/jamanetworkopen.2023.3376) Editor’s ...

Another crystalline layer on crystal surface as a precursor of crystal-to-crystal transition

Another crystalline layer on crystal surface as a precursor of crystal-to-crystal transition
2023-03-17
Ice surfaces have a thin layer of water below its melting temperature of 0℃. Such premelting phenomenon is important for skating and snowflake growth. Similarly, liquid often crystallizes into a thin layer of crystal on a flat substrate before reaching its freezing temperature, i.e. prefreezing. The thickness of the surface layer usually increases and diverges as approaching the phase transition (such as melting and freezing) temperature. Besides premelting and prefreezing, whether similar surface phenomenon ...

Team discovers how TKI cancer drugs cause inflammatory side effects

Team discovers how TKI cancer drugs cause inflammatory side effects
2023-03-17
Tyrosine kinase inhibitors are a type of targeted cancer medicine that can attack specific types of cancer cells and prevent them from multiplying. Although these inhibitors, called TKIs, can be very useful in fighting certain cancers, they also cause serious inflammatory side effects that limit their use. A Japanese research team has discovered the underlying mechanism that causes this inflammation. "This study revealed the underlying mechanism by which the TKIs cause inflammation, and therefore provides the molecular basis that is essential to overcome the inflammatory-based ...
