New miniaturized microscope offers unprecedented insight into nervous system function

A microscope about the size of a penny is giving scientists a new window into the everyday activity of cells within the spinal cord. The innovative technology revealed that astrocytes--cells in the nervous system that do not conduct electrical signals and were traditionally viewed as merely supportive--unexpectedly react to intense sensation.

Bacterial invasion of lungs can lead to inflammation in COPD

Chronic obstructive pulmonary disease (COPD) is a common smoking-related lung illness and the third leading cause of death in the United States. Scientists have long believed that inhaling toxic gases and particles from tobacco smoke causes inflammation of the small airways in the lungs, leading to the development of COPD. However, the theory doesn't explain why airway inflammation and disease progression continue even after the patient stops smoking.

Diabetic patients at risk for developing retinal diabetic neuropathy

A University of Iowa-led study of diabetes-related vision impairment holds good news -- and some bad news -- for patients with signs of these disorders.

Probiotic supplements may help treat post-menopausal osteoporosis

Probiotic supplements protected female mice from the loss of bone density that occurs after having their ovaries removed, researchers at Emory University School of Medicine and Georgia State University have shown.

Role of microRNAs in range of physiological activities

A group including scientists from the Florida campus of The Scripps Research Institute (TSRI) has been awarded a grant from the National Institute of Neurological Disorders and Stroke of the National Institutes of Health to study the role of microRNAs in a range of physiological activities, including memory, sleep, synapse function and movement.

ZOTEN nanoparticles can help develop natural immunity against genital herpes

An effective vaccine against the virus that causes genital herpes has evaded researchers for decades. But now, researchers from the University of Illinois at Chicago working with scientists from Germany have shown that zinc-oxide nanoparticles shaped like jacks can prevent the virus from entering cells, and help natural immunity to develop.

Novel spoken-language intervention could benefit children, adolescents with developmental disabilities

Sean Sawicki, who has fragile X syndrome, can be hard to understand and doesn't always have the attention span to carry on a sustained conversation. But a novel intervention developed by UC Davis MIND Institute researchers seems to be making a difference.

Musashi-2 protein regulates function, development of blood stem cells

Researchers at McMaster University's Stem Cell and Cancer Research Institute have made significant steps forward in understanding the stem cells of the human blood system after discovering how a key protein allows for better control and regeneration of these cells.

Latest popular diets have nutrient gaps

Paleo, high-protein, low-carb, gluten-free, vegetarian and vegan eating lifestyles have all exploded in popularity in the last few years. Whether people adopt these diets in order to lose weight or maintain overall wellness, consumers that follow them may be missing out on some essential nutrients. In the April issue of Food Technology Magazine, Linda Mila Ohr writes about the nutrient gaps in these various diets and how consumers can make sure they get the nutrients they need.

$Multidisciplinary experts assess effects of osteoporosis drugs on fracture healing$

Multidisciplinary experts assess effects of osteoporosis drugs on fracture healing

In people with osteoporosis, one fracture often leads to more fractures, and potentially a future of pain, disability, and poor quality of life. While studies have shown that such high-risk patients benefit from appropriate medication to reduce future fracture risk, more research is needed on the effect of osteoporosis medications on fracture healing.

Certain genetic markers linked with depression can also predict who may benefit from exercise

Call it personalized medicine for depression -- but the prescription in this case is exercise, which University of Florida Health researchers have found helps people with certain genetic traits.

Scientists build semantic atlas to show how human brain organizes language

What if a map of the brain could help us decode people's inner thoughts? Scientists at the University of California, Berkeley, have taken a step in that direction by building a "semantic atlas" that shows in vivid colors and multiple dimensions how the human brain organizes language. The atlas identifies brain areas that respond to words that have similar meanings.

Patients with impaired consciousness show uncontrolled communication between resting-state networks

An international research team has investigated interactions in different states of consciousness and has discovered that patients with severely impaired consciousness show a pathological or uncontrolled communication between resting-state networks.

Group of gamma-protocadherins linked with neurons help regulate growth of dendrites

When you think of a neuron, imagine a tree. A healthy brain cell indeed looks like a tree with a full canopy. There's a trunk, which is the cell's nucleus; there's a root system, embodied in a single axon; and there are the branches, called dendrites.

Scientists show how HIV enters female reproductive tract

Finding the vulnerable points where HIV enters the female reproductive tract is like searching for needles in a haystack. But Northwestern Medicine scientists have solved that challenge by creating a glowing map of the very first cells to be infected with a HIV-like virus.

Bonn researchers identify new technique to measure activity of brown fat cells

Brown fat cells can burn fat to generate heat. University of Bonn researchers have discovered a new method to measure the activity of brown fat cells in humans and mice. The researchers showed that microRNA-92a can be used as an indirect measure for the activity of energy consuming brown fat cells. They showed that a small blood sample was sufficient. Results were published in "Nature Communications," a well-known scientific journal.

Study reveals surprising results that may impair future therapeutic approaches in TGF-beta pathway

Researchers at Helmholtz Zentrum München describe how breast cancer cells challenged with a small-molecule inhibitor targeting specific invasive properties switch to an alternative mode-of-action, rendering them even more aggressive. The results may impair future therapeutic approaches in the TGF-beta pathway and are published in the journal 'Oncotarget'.

People's ability to smell declines with age

You not only pick up aromas through your nose, but also through your mouth while you chew your food. Some people simply can smell better than others and those may enjoy an enhanced flavor of foods. Unfortunately, for some, this ability decreases with age, report Tyler Flaherty and Juyun Lim of Oregon State University in the US in Springer's journal Chemosensory Perception.

Clinical study to evaluate safety of investigational cell therapy to treat chronic motor deficits after stroke

University Hospitals Case Medical Center is the first surgical site for a Phase 2b clinical trial study to further evaluate the safety and efficacy of an investigational cell therapy for the treatment of chronic motor deficit following an ischemic stroke.

New study on retroviral DNA could help improve treatments for HIV infection

When retroviruses such as HIV infect a cell, they first make a copy of their RNA genome in the form of DNA. The relatively short viral DNA strand then moves to the cell nucleus, where it inserts itself into the host cell's DNA.
