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 demonstrate epigenetic memory transmission via sperm

A new study suggests that if the epigenetics of sperm chromosomes are altered by the environment a father experiences, then this could affect offspring’s health.

Researchers identify series of molecules involved in regeneration of damaged nerves

Researchers at Nagoya University have identified the series of molecules involved in the regeneration of damaged nerves in roundworm, showing that it largely overlaps with the signals used by the intrinsic removal system to take up and process dying cells.

Study findings shed light on fundamental feature of nerve repair

Through a study of roundworm nerve cells with severed axons, researchers at Nagoya University showed that a signaling cascade that normally functions in promoting the phagocytosis of apoptotic cells also acts in inducing axon regeneration.

Research uncovers unexpected upside of E. coli

Best known as a pathogen that causes food poisoning or steals nutrients away from its host, the E. coli bacterium actually plays a critical role in promoting health by producing a compound that helps cells take up iron, new CU Boulder research shows.

Research identifies cell signaling pathways related to endocannabinoid system in worms

Like mammals, parasitic worms have an endocannabinoid system that may help the worm and the hosts it infects survive by reducing pain and inflammation in the host, according to a "wild" new discovery by an interdisciplinary research team at the University of California, Riverside.

Scientists turn to C. elegans for new model of peripheral neuropathy

Studying transthyretin amyloidoses-;a group of progressive nerve and cardiac degenerative diseases caused by the buildup of misfolded transthyretin proteins in the body-;has long been hampered by the lack of animal models of the disease.

Researchers report new way to map the inner workings of a living cell

Imaging tools like X-rays and MRI have revolutionized medicine by giving doctors a close up view of the brain and other vital organs in living, breathing people. Now, Columbia University researchers report a new way to zoom in at the tiniest scales to track changes within individual cells.

Mosquito screening found to be useful for tracking recurrence of lymphatic filariasis

To ensure elimination of the Wuchereria bancrofti, a parasitic roundworm that causes lymphatic filariasis, public health workers must follow up mass drug administration with careful monitoring for recurrence.

Rockefeller scientists shed new light on the neuroscience of sleep

A good night of sleep entails about eight hours of blissful immobility--a state of near paralysis that, though welcome at night, would be inconvenient during the day. In a recent paper published in Cell Reports, Rockefeller scientists shed new light on the transitions between a wakeful, active state and the stillness of sleep.

Scientists identify new inherited neurodevelopmental disease

Researchers have identified a new inherited neurodevelopmental disease that causes slow growth, seizures and learning difficulties in humans.

Gut microbes linked to severity of intestinal parasitic worm infections

A new study indicates that the kinds of microbes living in the gut influence the severity and recurrence of parasitic worm infections in developing countries.

Study reveals key function of ALS-linked protein

The protein FUS, whose mutation or disruption causes many cases of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), works as a central component of one of the most important regulatory systems in cells, according to a new study in Molecular Cell from scientists at Johns Hopkins Bloomberg School of Public Health.

Biologists discover new genetic pathway for injured nerve regeneration

On the hunt for genes involved in regenerating critical nerve fibers called axons, biologists at the University of California San Diego came away with a surprise: The discovery of a new genetic pathway that carries hope for victims of traumatic injuries-; from stroke to spinal cord damage.

Sleeping sickness actually caused by acceleration of biological clocks

Sleeping sickness could use a more encompassing moniker. An international study from the O'Donnell Brain Institute shows one of Africa's most lethal diseases is actually a circadian rhythm disorder caused by the acceleration of biological clocks controlling a range of vital functions besides sleep.

UT Southwestern researchers identify potential approach to suppress lethal parasitic infections

UT Southwestern Medical Center researchers have identified a chemical that suppresses the lethal form of a parasitic infection caused by roundworms that affects up to 100 million people and usually causes only mild symptoms.

Scientists one step closer to solving puzzle of how nerves can self-heal

Monash University scientists are one step closer to solving the riddle of how nerves can self-heal. The scientists from the Biomedicine Discovery Institute (BDI) have found signals in the tiny transparent roundworm that control the mechanism by which severed nerves self-heal.

Study elucidates how aerobic exercise protects the sick heart

Regular exercise is considered an important form of treatment for heart failure, a condition in which the heart is unable to pump enough blood to meet the body's needs.

Scientists map learning and memory center of fruit fly larva brain

A Johns Hopkins University mathematician and computer scientist joined an international team of neuroscientists to create a complete map of the learning and memory center of the fruit fly larva brain, an early step toward mapping how all animal brains work.

Hidden parasite: Raccoon roundworms may infect people more than previously assumed

The raccoon that topples your trashcan and pillages your garden may leave more than just a mess. More likely than not, it also contaminates your yard with parasites -- most notably, raccoon roundworms (Baylisascaris procyonis).

Tumorigenesis may be induced from neighboring tissues, study suggests

Current view is that cancer development is initiated from cells that acquire initial DNA mutations. These in turn provoke additional defects, and ultimately the affected cells begin to proliferate in an uncontrolled manner to develop primary tumors.
