Engineers with the University of Cincinnati have created a tiny portable lab that plugs into your phone, connecting it automatically to a doctor's office through a custom app UC developed.
The lab the size of a credit card can diagnose infectious diseases such as coronavirus, malaria, HIV or Lyme disease or countless other health conditions like depression and anxiety.
The patient simply puts a single-use plastic lab chip into his or her mouth then plugs that into a slot in the box to test the saliva.
Tinder's meteoric rise in popularity has cemented its position as the go-to dating app for millions of young and not-so-young users. Although it is widely known as a platform to facilitate hookups and casual dating, some of the app's estimated 50 million+ worldwide users are employing it for something altogether different.
New Orleans, LA - Pooja Mehta, M.D., clinical assistant professor of obstetrics & gynecology at LSU Health New Orleans School of Medicine, was a member of a research team that found 13% of deaths occurring during or up to one year after pregnancy among Louisiana women in 2016-17 were homicides. Results are published online in JAMA Pediatrics, available here.
HOUSTON -- A study led by The University of Texas MD Anderson Cancer Center furthered understanding about mitochondria, the cell components known as the "powerhouse of the cell." Knowing more about the genome is crucial given that mitochondria play important roles in tumorigenesis.
Most cells in the tissues of most organisms proliferate through somatic cell division (mitosis). This is a continuous cycle where a single cell doubles its genetic information (chromosomes) and divides equally to create two copies of the original cell. In contrast, germ (egg and sperm) cells are produced through a special type of cell division called meiosis, which takes place in the gonads. This process begins like normal mitosis but switches after some time to create four genetically dissimilar germ cells that have half the original cell's genetic material.
NEW YORK -- The protein tau has long been implicated in Alzheimer's and a host of other debilitating brain diseases. But scientists have struggled to understand exactly how tau converts from its normal, functional form into a misfolded, harmful one. Now, researchers at Columbia University's Zuckerman Institute and Mayo Clinic in Florida have used cutting-edge technologies to see tau in unprecedented detail. By analyzing brain tissue from patients, this research team has revealed that modifications to the tau protein may influence the different ways it can misfold in a person's brain cells.
DURHAM, N.C. -- Biomedical engineers at Duke University have developed the most advanced disease model for blood vessels to date and used it to discover a unique role of the endothelium in Hutchinson-Gilford Progeria Syndrome. Called progeria for short, the devastating and extremely rare genetic disease causes symptoms resembling accelerated aging in children.
ANN ARBOR, Michigan -- Women with early stage breast cancer who test positive for an inherited genetic variant are not always receiving cancer treatment that follows current guidelines, a new study finds.
An inherited gene can increase risk of developing a second breast cancer, so strategies such as removing a woman's breasts or ovaries are intended to prevent a future cancer. But women who have already been diagnosed with breast cancer must also consider how best to treat the existing tumor.
In mammalian adult brains, neural stem cells are only present in few specific parts, so called niches. Only these niches are capable of generating new neurons. For the first time, researchers defined the proteome of these niches, the entire set of expressed proteins, and compared it to other regions of the brain. The findings help to identify key regulators for neurogenesis, an important step towards activating neurogenesis after brain injuries.
From plastics to pesticides, it seems like every week delivers fresh news about the dangers of endocrine disruptors--chemicals in the environment that alter the body's hormones and can lead to reproductive, developmental, neurologic and immune problems and cancer.
Industry regulation and individual consumer choice can reduce exposure to such chemicals, but there are few options to counteract damage that has already occurred.
Now new research conducted in worms suggests a path toward changing that.
Survival may more than double for adults with glioblastoma, the most common and deadly type of brain tumor, if neurosurgeons remove the surrounding tissue as aggressively as they remove the cancerous core of the tumor.
This discovery, reported in a retrospective study headed by researchers at UC San Francisco, is welcome news for those in the glioblastoma community, which celebrated its last breakthrough in 2005 with the introduction of the chemotherapy drug temozolomide.
Materials called perovskites show strong potential for a new generation of solar cells, but they've had trouble gaining traction in a market dominated by silicon-based solar cells. Now, a study by researchers at MIT and elsewhere outlines a roadmap for how this promising technology could move from the laboratory to a significant place in the global solar market.
The situation is extraordinary: there have only ever been four declarations of public health emergencies of international concern in the past and now there are two at the same time. Whilst the risks associated with the novel coronavirus are still unclear, people in the Democratic Republic of the Congo are still battling with an outbreak of the deadly Ebola virus which has been ongoing since 2018 and has already claimed over 2000 lives. One issue is the precise characterisation of the pathogen because the ebolaviruses, like lots of viruses, appear in various genetic forms.
Hip replacements, severe burns, spinal cord injuries, blast injuries, traumatic brain injuries--these seemingly disparate traumas can each lead to a painful complication during the healing process called heterotopic ossification. Heterotopic ossification is abnormal bone formation within muscle and soft tissues, an unfortunately common phenomenon that typically occurs weeks after an injury or surgery. Patients with heterotopic ossification experience decreased range of motion, swelling and pain.
An international study, in which the University of Granada (UGR) participated, has confirmed that intergroup contact between advantaged groups (ethnic majorities and cis-heterosexuals) and disadvantaged groups (ethnic minorities and sexual minorities) is not always positive as a strategy for reducing prejudice toward disadvantaged groups, contrary to the view traditionally defended in the Social Psychology field.
