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 reveal what cells respond to anesthesia in C. elegans

Physicians use inhalation anesthetics in a way that is incredibly safe for patients, but very little is known about the intricacies of how these drugs actually work in children and adults. Now, researchers have uncovered what cells respond to anesthesia in an organism known as the C. elegans, according to a new study from the Seattle Children's Research Institute. C. elegans is a transparent roundworm used often in research.

FLI, IZW partner to begin ageing research project in 2012

Jena`s Leibniz Institute for Age Research - Fritz Lipmann Institute (FLI) and Berlin`s Leibniz Institute for Zoo and Wildlife Research (IZW) from Germany are jointly starting a project for ageing research in 2012.

Considering varying extent to which genes are turned on or off can help develop personalised, predictive medicines

The vast majority of genetic disorders (schizophrenia or breast cancer, for example) have different effects in different people. Moreover, an individual carrying certain mutations can develop a disease, whereas another one with the same mutations may not. This holds true even when comparing two identical twins who have identical genomes. But why does the same mutation have different effects in different individuals?

Simple roundworm may serve as ideal skin wound healing lab model

The lowly and simple roundworm may be the ideal laboratory model to learn more about the complex processes involved in repairing wounds and could eventually allow scientists to improve the body's response to healing skin wounds, a serious problem in diabetics and the elderly.

Researchers gain insight on how roundworm's brain operates as it moves

Using new optical equipment, a team of 11 researchers put roundworms into a world of virtual reality, monitored both their behavior and brain activity and gained unexpected information on how the organism's brain operates as it moves.

Fred Hutchinson Cancer Research Center scientist wins NIH Director's Early Indpendence Award

Carissa Perez Olsen, Ph.D., a Weintraub Scholar in the Basic Sciences Division of Fred Hutchinson Cancer Research Center, is the recipient of the National Institutes of Health Director's Early Independence Award, announced today. She is among the first group of 10 junior U.S. investigators to receive the honor.

Freiburg researchers receive European Research Council Starting Grants

Marta Artal Sanz, Thomas Brox, Winfried Römer, and Oliver Schilling from the University of Freiburg have been selected for one of the most prestigious European grants for young researchers: The European Research Council (ERC) has awarded them a total of 5.8 million euros in ERC Starting Grants for new projects.

Scientists discover genetic switch to prevent neurodegenerative diseases

Scientists at Northwestern University report a surprising discovery that offers a possible new route for the treatment of neurodegenerative diseases. In a study of the transparent roundworm C. elegans, they found that a genetic switch in master neurons inhibits the proper functioning of protective cell stress responses, leading to the accumulation of misfolded and damaged proteins.

Flatworms provide new insight into organ regeneration, evolution of mammalian kidneys

Our bodies are perfectly capable of renewing billions of cells every day but fail miserably when it comes to replacing damaged organs such as kidneys. Using the flatworm Schmidtea mediterranea-famous for its capacity to regrow complete animals from minuscule flecks of tissue-as an eloquent example, researchers at the Stowers Institute for Medical Research demonstrated how our distant evolutionary cousins regenerate their excretory systems from scratch.

Scientists study how nervous system translates sensory information into coordinated motor output

Escape responses are some of the most studied behaviors by neurobiologists who want to understand how the brain processes sensory information. The ability to evade predators plays a vital role in the process of natural selection.

Heartworm medication Ivermectin prevents malaria transmission in Africa

A cheap, common heartworm medication that is already being used to fight other parasites in Africa could also dramatically interrupt transmission of malaria, potentially providing an inexpensive tool to fight a disease that kills almost 800,000 people each year, according to a new study published in the July edition of the American Journal of Tropical Medicine and Hygiene.

Study: Dyslexia gene controls cilia in brain neurons

Scientists at Karolinska Institutet in Sweden have discovered that a gene linked to dyslexia has a surprising biological function: it controls cilia, the antenna-like projections that cells use to communicate.

Research provides new insights into how cilia are assembled on the cell surface

Body cells detect signals that control their behavior through tiny hairs on the cell surface called cilia. Serious diseases and disorders can result when these cilia do not work properly.

DNA rearrangements in roundworm chromosomes offer insight into genome duplications in developing tumors

A study of DNA rearrangements in roundworm chromosomes may offer new insight into large-scale genome duplications that occur in developing tumors.

Unanticipated structure at chromosome ends could be key ingredient in biological 'elixir of life'

In stark contrast to normal cells, which only divide a finite number of times before they enter into a permanent state of growth arrest or simply die, cancer cells never cease to proliferate. Now, scientists at the Salk Institute for Biological Studies have uncovered an important clue to one of the mechanisms underlying cancer cell immortality.

Scientists develop new model for neurodegenerative disease

A team of scientists at the University of California, San Francisco has developed a new model for how inherited genes contribute to a common but untreatable and incurable neurodegenerative disease.

Study: Roundworm protein can suppress inflammation in patients with sepsis

Research by the University of Liverpool has found that systemic inflammation caused by sepsis can be suppressed by a protein which occurs naturally in a type of roundworm.

Scientists demonstrate that environmental lithium uptake promotes longevity

Professor Dr. Michael Ristow's team along with Japanese colleagues from universities in Oita and Hiroshima have demonstrated by two independent approaches that even a low concentration of lithium leads to an increased life expectancy in humans as well as in a model organism, the roundworm Caenorhabditis elegans.

Deactivation of CRTC1 protein increases lifespan

Substantial evidence suggests that lifespan is increased if an organism restricts its daily calorie intake, a spartan regime that some say works by just making life seem longer. A team of scientists from the Salk Institute of Biological Studies has discovered a molecular switch flipped by hunger that could not only make longevity more appetizing but identify drug targets for patients with aging-related diseases such as type II diabetes or cancer.

Researchers discover how Ras oncogene chooses a signaling pathway

The National Cancer Institute estimates that more than 43,000 Americans were diagnosed with pancreatic cancer last year and more than 36,000 died from the disease. Despite advances in genetic science showing that the Ras oncogene is mutated in virtually all pancreatic cancers, scientists have been frustrated by the complexity of the signaling pathways in humans, which make it difficult to pinpoint potential therapeutic targets.
