Tackling the hurdle of tumor formation in stem cell therapies

EPHA2 marker in stem cells

•

ScienceDaily / 9min

Pluripotent stem cells (PSCs), which can virtually form any cell type, have great potential in the field of regenerative medicine. However, the growth of tumors after PSC transplantation remains to be an unresolved issue. Now, through extensive experiments, researchers have revealed a key role of EPHA2, a membrane protein, on stem cell function and tumor formation after PSC transplantation. Their

Traumatic brain injury strikes 1 in 8 older Americans

ScienceDaily / 9min

Some 13% of older adults are diagnosed with traumatic brain injury (TBI), according to a new study. These injuries are typically caused by falls from ground level. Researchers followed about 9,200 Medicare enrollees, whose average age was 75 at the start of the study, and found that contrary to other studies of younger people, being female, white, healthier and wealthier was associated with higher

Mediterranean diet tied to one-fifth lower risk of early death in women

In a new study that followed more than 25,000 initially healthy U.S. women for up to 25 years, researchers found that participants who had greater Mediterranean diet intake had up to 23% lower risk of all-cause mortality, with benefits for both cancer mortality and cardiovascular mortality.

New study reveals key protein that could help prevent excessive bone loss in osteoporosis

Key protein prevents osteoporosis bone loss

•

ScienceDaily / 10min

Osteoporosis is characterized by the weakening of bones, making them fragile and prone to breakage. Excessive activity of 'osteoclasts' or bone-absorbing cells leads to bone loss. Targeting osteoclast differentiation is therefore, a potential therapeutic strategy. In a new study, researchers have discovered a novel role of the Ctdnep1 phosphatase in suppressing osteoclast differentiation and bone

Tracing the evolution of ferns' surprisingly sweet defense strategy

ScienceDaily / 10min

Plants and the animals that eat them have evolved together in fascinating ways, creating a dynamic interplay of survival strategies. Many plants have developed physical and chemical defenses to fend off herbivores. A well-known strategy in flowering plants is to produce nectar to attract 'ant bodyguards.' Recent research explores the evolution of this same defense strategy in ferns.

New research platform assesses brain cancer mutations during surgery

ScienceDaily / 10min

Brain cancer is difficult to treat when it starts growing, and a prevalent type, known as a glioma, has a poor five-year survival rate. In a new study, researchers report on a new surgical platform used during surgery that informs critical decision-making about tumor treatment within minutes.

Study examines prescribing patterns of drug associated with cognitive impairment

ScienceDaily / 10min

A new study is one of the first explorations of prescribing patterns of tricyclic antidepressants for treatment of diabetic peripheral neuropathy at healthcare facilities predominantly serving diverse populations of low socioeconomic status. The current body of evidence, much of it established and confirmed in studies by scientists, supports the existence of a relationship between long-term use of

Advancing cancer detection by counting tiny blood-circulating particles

New method detects cancer accurately

•

ScienceDaily / 10min

A researcher is reporting a new method to detect cancer which could make cancer detection as simple as taking a blood test. With a 98.7% accuracy rate, the method has the potential to detect cancer at the earliest stage and improve treatment efficacy.

AIM algorithm enhances super-resolution microscope images in real time

When trying to measure molecular structures with nanometer precision, every bit of noise shows up in the data: someone walking past the microscope, tiny vibrations in the building and even the traffic outside. A new processing technique removes noise from optical microscope data in real time, allowing scientists to track individual molecules over 10 times more precisely than was possible before.

Generative AI to protect image privacy

ScienceDaily / 10min

Image privacy could be protected with the use of generative artificial intelligence. Researchers created a system which replaces parts of images that might threaten confidentiality with visually similar but AI-generated alternatives. Named 'generative content replacement,' in tests, 60% of viewers couldn't tell which images had been altered. The researchers intend for this system to provide a more

Researchers uncover surprising role of opioid receptors in gut development

ScienceDaily / 11min

Researchers have revealed a previously unknown function of opioid receptors in the development of the enteric nervous system (ENS), often referred to as the 'brain in the gut.' This discovery challenges conventional understanding of opioid receptors, shedding new light on their significance beyond pain management and addiction.
