A study in cocaine-addicted rats reports long-lasting increases in the number of neurons that produce orexin—a chemical messenger important for sleep and appetite—that may be at the root of the addiction
Sun Tzu, the general of ancient China, wrote in his enduring military treatise "The Art of War" of the importance of knowing one's enemy. The idea resonates strongly with Athena Aktipis, a scholar of many titles at Arizona State University who studies cooperation among living things
Schizophrenia, an often severe and disabling psychiatric disorder, affects approximately 1 percent of the world's population. While research over the past few years has suggested that desynchronization of neurons may be the cause of its neuropsychiatric symptoms, including memory disorders, hyperactivity, and hallucinatory phenomena, the cellular origin of such desynchronization remains poorly understood
University of Otago researchers have helped characterize a genetic variant that enables new understanding of why some people are at risk of gout, a painful and debilitating arthritic disease
An international research team led by Wolfgang Weninger has discovered a previously unknown virus that acts as a "driver" for certain kidney diseases (interstitial nephropathy). This "atypical" virus, which the scientists named "MKPV" (for Mouse Kidney Parvovirus), belongs to the family of parvoviruses. The results of the study have now been published in the leading international journal Cell
Our study was designed to compare the diagnostic efficacies of integrated 99mTc-HYNIC-PEG4-E[PEG4-c(RGDfK)]2 (99mTc-3PRGD2) single-photon emission computed tomography (SPECT) images and computed tomography (CT) images in lymph node metastasis in the patients with esophageal cancer.??????
The combination of a new sequencing technique and machine learning can speed up the diagnosis of diseases in newborns and reduce false-positive results, Yale researchers and their collaborator's report
Cerebral palsy (CP) is the most common physical disability originating in childhood. Approximately 2 of every 1000 babies born acquire this condition that results from abnormal development or damage to the brain. Since CP affects a child's ability to control his or her muscles, physical activity can be difficult or even impossible
Many eye diseases, including diabetic retinopathy and macular degeneration, exhibit an increased permeability of blood vessels in the macula (central) portion of the retina leading to abnormal fluid accumulation and vision loss
Poor maternal bonding is more common for children born to women who are denied access to abortion, according to a study published online Sept. 4 in JAMA Pediatrics
Think of it as a cancer therapy zag instead of a zig. While many groups are developing cancer therapies to target proteins and pathways that are highly active in cancer cells, a team of investigators from Brigham and Women's Hospital and Boston Children's Hospital, with collaborators at Memorial Sloan Kettering Cancer Center, is taking a new approach that allows them to go after what is not there
As we go about our daily lives, we are exposed to many different chemicals that could have negative effects on our hormones. These hormonal changes have been linked to several adverse health outcomes such as breast cancer and cardiovascular disease
