Roundworm News and Research

RSS

Roundworm infection, or toxocariasis, is a zoonotic disease — a disease that can be transmitted from animals to humans. Dogs and cats are the definitive hosts for the roundworm species that commonly cause human disease.

Researchers explore why women have ubiquitous survival advantage than men

Women live longer than men. This simple statement holds a tantalizing riddle that Steven Austad, Ph.D., and Kathleen Fischer, Ph.D., of the University of Alabama at Birmingham explore in a perspective piece published in Cell Metabolism on June 14.

Smell or taste of food can shorten lifespan by affecting sensory neurons

Animals can perceive changes in many environmental factors such as temperature and the taste or smell of foods. This is achieved by specialized nerve cells called sensory neurons. Interestingly, sensory neurons have been known to control the rate of aging in various animals, including the tiny free living roundworm C. elegans.

Glial cells can modulate specific nerve endings in the brain, find Rockefeller scientists

More than half of our brains are made up of glial cells, which wrap around nerve fibers and insulate them--similarly to how the plastic casing of an electric cable insulates the copper wire within--allowing electrical and chemical impulses to travel faster.

GHIT Fund invests in two innovative malaria eradication tools

The Global Health Innovative Technology Fund (GHIT Fund) announced today that it’s investing US$1,383,785 in a pair of innovative malaria eradication tools—a vaccine that could block transmission of two species of the deadly disease and a rapid field test that can reveal a malaria infection in minutes.

Study uncovers role of small RNAs in fine-tuning egg development

All multicellular organisms that reproduce sexually rely on eggs to support early life. Researchers at University of California, San Diego School of Medicine and Ludwig Cancer Research used the tiny roundworm C. elegans as a model to better understand how eggs enable embryonic development, using only the materials already present in them.

Researchers link AFD activity to sensory responses and behavior

When the surrounding environment makes us uncomfortable, we are inclined to move to a more agreeable one. Studies have shown that animals do the same. They organize sequences of movements to migrate to preferred environments. Understanding how environmental information is converted to sensory information in the brain is vital for a deeper understanding of animal behavior and human perception.

Role of dietary restriction in lifespan extension

The role of dietary restriction in extending lifespan is the subject of research being conducted at the MDI Biological Laboratory in Bar Harbor, Maine, by visiting scientist Markus Schosserer, Ph.D., of the biotechnology department at the University of Natural Resources and Life Sciences, Vienna, in Austria.

Real maple syrup shows promise in protecting brain health

As part of a two-day symposium at the annual meeting of the American Chemical Society, a group of international scientists shared promising results of 24 studies exploring the beneficial effects of natural products on the prevention of neurodegenerative diseases, particularly Alzheimer's disease.

Animal study shows link between oxygen-sensing neurons and fat-burning circuit

A new study in animal models, led by scientists at The Scripps Research Institute (TSRI), is the first to show that oxygen sensing in the brain has a role in metabolism and sensing an organism's internal state.

Genes vital for age-related cognitive declines in memory identified in adult worm neurons

Researchers from Princeton University have identified genes important for age-related cognitive declines in memory in adult worm neurons, which had not been studied previously. The research, published in the journal Nature, could eventually point the way toward therapies to extend life and enhance health in aging human populations.

Rutgers scientists uncover biological pathways that provide insight into tiny cell bubbles

Rutgers scientists have uncovered biological pathways in the roundworm that provide insight into how tiny bubbles released by cells can have beneficial health effects, like promoting tissue repair, or may play a diabolical role and carry disease signals for cancer or neurodegenerative diseases like Alzheimer's.

Roundworm infection increases fertility among women in the Amazon

Parasitic worms can live inside humans gaining nourishment from the food we ingest (roundworms) or from our blood (hook worms), whilst being safe from predators. Although roundworm infections are generally symptomless they are not something any of us would choose to have. However, it has recently been found that infection with roundworm increases a woman's fertility.

New anti-malarial ‘biobricks' could pave way for easier, cost-effective production of artemisinin drug

Students from Trinity College Dublin have successfully created anti-malarial ‘biobricks', which could pave the way for easier and more cost-effective production of the key drug artemisinin.

Targeting invasive cells could be a new strategy to treat metastatic cancer, say Stony Brook researchers

Most cancer drugs are designed to target dividing cells, but a new study by Stony Brook University researchers suggests that targeting invasive cells may be a new strategy to treat metastatic cancer.

Immune system linked to death of motor neurons in Amyotrophic lateral sclerosis

A previously unknown link between the immune system and the death of motor neurons in Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, has been discovered by scientists at the CHUM Research Centre and the University of Montreal. The finding paves the way to a whole new approach for finding a drug that can cure or at least slow the progression of such neurodegenerative diseases as ALS, Alzheimer's, Parkinson's and Huntington's diseases.

GBD analysis shows over 95% of global population has health problems

Just one in 20 people worldwide (4·3%) had no health problems in 2013, with a third of the world's population (2·3 billion individuals) experiencing more than five ailments, according to a major new analysis from the Global Burden of Disease Study (GBD) 2013, published in The Lancet.

Space Aging study may help identify novel genes linked to longevity

The plot of many a science fiction TV series or movie revolves around the premise that people traveling long distances in space age more slowly than their counterparts on Earth. Now, tiny worms who spent time aboard the International Space Station could help humans understand more about the effects of aging in space for real.

Serotonin and TGF-beta pathways link diet to health and ageing

Diet exerts a major impact on health and ageing. The nervous system plays an important role in this process but, thus far, how food signals are interpreted by the nervous system has been a mystery.

Study reveals how cell's protein quality control mechanism helps combat neurodegenerative diseases

A molecular pathway known to suppress tumors appears to also be a major player in clearing cells of damaged proteins implicated in neurodegenerative diseases such as ALS and certain types of dementia, new research in roundworms and human cells suggests.
