Parental knowledge and attitudes toward HIV preventive treatment for their adolescent children

HIV pre-exposure prophylaxis (PrEP), a daily regimen of two medications in a single pill, could prevent many new HIV infections, especially in at-risk populations. For example, research shows PrEP could prevent around 70 percent of new HIV infections in adolescent cisgender sexual minority males (ASMM) and transgender and gender diverse adolescents (TGDA), populations that are disproportionately affected by the disease. However, despite growing awareness of PrEP among ASMM/TGDA, uptake of the treatment is still less than 5 percent. A new study published in the journal Sexuality Research and Social Policy looks ...

Texas A&M researchers discover new circuit element

Dr. H. Rusty Harris, associate professor in the Department of Electrical and Computer Engineering at Texas A&M University, has identified a new circuit element known as a meminductor. A circuit element is an electrical component used to help direct and control the flow of electricity through an electrical circuit. The classical three are known as the resistor, capacitor and inductor. Two additional circuit elements, the memristor and the memcapacitor, were only discovered in the past 15 years. These newer circuit elements are known as the mem- versions of their classical counterparts, and their current and voltage properties are dependent ...

Endocrine Society alarmed by Texas court ruling banning mifepristone

WASHINGTON—The Endocrine Society is deeply concerned about a Texas ruling that reverses the U.S. Food and Drug Administration’s (FDA) approval of mifepristone, a drug used to treat Cushing’s syndrome and to end pregnancy safely and effectively. Last week, two conflicting federal court decisions in Texas and Washington state left access to mifepristone unclear for both the treatment of Cushing’s syndrome and for medical abortions. The Texas court ruled to ban mifepristone, taking away the FDA's authority to regulate the safety of medications. The judge paused ...

Mint flavor makes vape juice more toxic, damaging to lungs

PITTSBURGH, April 10, 2023 – Adding mint flavor to e-cigarette liquids produces more vapor particles and is associated with worse lung function in those who smoke, report researchers from the University of Pittsburgh in Respiratory Research today. Using a specially designed robotic system that mimics the mechanics of human breathing and vaping behavior, researchers showed that commercially available e-cigarette liquids containing menthol generate a greater number of toxic microparticles compared to menthol-free juice. An accompanying analysis of patient records from a cohort of e-cigarette smokers revealed that menthol vapers took shallower breaths and ...

View interpolation networks for reproducing the material appearance of specular objects

With the spread of Internet shopping nowadays, purchasing products online has become possible and common. However, in many cases, because users are presented with few photographs of products and cannot actually hold the products, they may be unable to perceive the material of the products. In this study, we proposed view interpolation networks for reproducing material appearances. We implemented U-Net, an existing image transformation network, and a network that used additional information in the middle layer of U-Net. The networks were trained to generate images from the intermediate ...

Unrolling a rain-guided detail recovery network for singleimage deraining

Rain streaks of different shapes, sizes, and directions obscure image background scenes, resulting in image degradation, including intensity fluctuation, color distortion, or even content alteration. Such degradation impairs the visual quality of an image and leads to undesirable performance of many outdoor computer vision systems that require high-quality images. Therefore, image deraining must be performed, and effective deraining methods should be developed. In this study, we addressed the problem of single-image rain removal. We propose a novel unrolling rain-guided detail recovery network ...

Impact of coronavirus on states’ fertility rates tracked with economic, social, and political divides

Experts have found that at the start of the COVID-19 outbreak in early 2020, Americans chose not to become pregnant as they grappled with stay-at-home restrictions, anxiety, and economic hardship. Now, a new study led by researchers at NYU Grossman School of Medicine shows that some states actually experienced steeper decreases in fertility than others. The findings revealed that nine months after the pandemic began, there were 18 fewer births a month per 100,000 women of reproductive age across the U.S. compared with the year ...

New therapy harnesses patients’ blood cells to fight tumors

Adoptive cell therapy (ACT) has become a promising immunotherapy tool to help treat advanced melanoma. The therapy, which harnesses immune cells collected from the patient’s own tumors, could provide a new treatment option to cancer patients, potentially bypassing radiation therapies and harsh chemotherapy drugs. For the first time, Northwestern University scientists have discovered it is possible to isolate a tumor’s attack cells non-invasively from blood, rather than from tumors. The finding opens the door for ACT to treat harder-to-reach cancer types and makes it a more viable option ...

Prior treatments influence immunotherapy response in advanced melanoma

Research led by scientists at UCLA Jonsson Comprehensive Cancer Center found that responses to a type of immunotherapy called PD-1 checkpoint blockade in patients with advanced melanoma depended on whether or not they had previously received another immunotherapy – CTLA-4 blockade – as well as other factors. Their findings, based on analysis of seven data sets generated over the past decade, which included results of tumor biopsies from more than 500 patients, are published in Cancer Cell. “In our large set of data, features that have been used to predict response ...

Trees in areas prone to hurricanes have strong ability to survive even after severe damage

As their plane flew low on its approach to land at the airport on the island of Dominica, researchers from Clemson and Harvard universities looked out the window to see miles of forests with trees that looked like matchsticks. It was nine months after the island in the West Indies had taken a direct hit from Category 5 Hurricane Maria. But when the researchers actually got into the forests and examined the trees more closely, they discovered that while 89% of the trees sustained damage — 76% of which had major damage —only 10% were immediately killed. Many of the trees had resprouted. “These ...

Temperature is stronger than light and flow as driver of oxygen in US rivers

UNIVERSITY PARK, Pa. — The amount of dissolved oxygen in a river is a matter of life or death for the plants and animals living within it, but this oxygen concentration varies drastically from one river to another, depending on their unique temperature, light and flow. To better understand which factor has the greatest impact on the concentration of dissolved oxygen, researchers at Penn State used a deep learning model to analyze data from hundreds of rivers across the United States. Oxygen concentration is an important measure of water quality because fish and other aquatic organisms require dissolved oxygen to breathe, according to Wei Zhi, assistant ...

Easy and quick binding of targeting molecule and radiotracer to drug nanocarrier for cancer therapy

BIRMINGHAM, Ala. – An ideal nanovesicle to fight cancer would have three functionalities: 1) a precision-targeting molecule to preferentially bind it to surface markers on cancer cells, 2) a strongly bound radionuclide signal that would allow a PET scan to locate the vesicles in the body, and 3) the ability to carry and release a drug treatment, such as a chemotherapy, at the cancer tumor. It would also meet two other requirements — having a simple and facile method of manufacture, and being biocompatible and biodegradable in the body. A University of Alabama at Birmingham team has now described a tiny polymersome that — in initial preclinical ...

Light pollution may extend mosquitoes’ biting season

COLUMBUS, Ohio – A new study’s finding that urban light pollution may disrupt the winter dormancy period for mosquitoes that transmit West Nile virus could be considered both good news and bad news. The good news is that the disease-carrying pests may not survive the winter if their plans to fatten up are foiled. The bad news is their dormancy period, known as diapause, may simply be delayed – meaning they’re biting humans and animals longer into the fall. “We see the highest levels ...

Can alcohol-associated burn injuries impair cognitive function?

The relationship between alcohol use and burn injuries is a negative one in multiple ways. Not only are about 50% of adults who sustain burn injuries intoxicated at the time of injury, suggesting that alcohol use may have contributed to the incident, but alcohol use among burn-injured patients is associated with more severe complications, delayed recovery, and increased morbidity and mortality. “Return to work or normal life can be impaired or delayed for burn-injured patients who use alcohol,” says Elizabeth Kovacs, PhD, vice chair of research and professor of GI, trauma, and endocrine surgery ...
