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.

Whole-brain imaging data provides insights into roundworm neural activity

Joint research led by Yu Toyoshima and Yuichi Iino of the University of Tokyo has demonstrated individual differences in and successfully extracted commonalities from the whole-brain activity of roundworms.

UTA biology professor awarded NIH grant for new super-resolution microscope

UTA will soon add a new piece of cutting-edge equipment to its already impressive and growing research armamentarium-;a type of super-resolution microscope (SRM) that allows biologists to see structures within a cell in even finer detail.

Diabetes drug promotes longevity by stimulating the body's production of ether lipids

Metformin, the most commonly used drug to treat type 2 diabetes, not only lowers blood sugar levels but has revealed to extend lifespan in C. Elegans -- an animal model that shares similar metabolic systems with humans and are often used to model human diseases.

Researchers pioneer a new method for fast miRNA amplification and detection

In the early 1990s, scientists who were studying the development of a roundworm identified a small RNA molecule that regulated the expression of specific genes.

New finding in roundworms upends classical thinking about animal cell differentiation

Researchers have spotted how specific proteins within the chromosomes of roundworms enable their offspring to produce specialized cells generations later, a startling finding that upends classical thinking that hereditary information for cell differentiation is mostly ingrained within DNA and other genetic factors.

Significance of mathematical modeling in understanding complex biological processes

Humans and animals detect different stimuli such as light, sound, and odor through nerve cells, which then transmit the information to the brain. Nerve cells must be able to adjust to the wide range of stimuli they receive, which can range from very weak to very strong. To do this, they may become more or less sensitive to stimuli (sensitization and habituation), or they may become more sensitive to weaker stimuli and less sensitive to stronger stimuli for better overall responsiveness (gain control). However, the exact way this happens is not yet understood.

Study: FER1L5 protein essential for sperm to undergo acrosome reaction and male fertility

Fertilization is the union of two cells: an egg and a sperm. Before the egg and the sperm fuse, an event known as the "acrosome reaction" needs to occur in the sperm.

Exposure to parasitic roundworm linked with lower lung-function and asthma in younger men

By looking at the exposure to the parasitic roundworm Ascaris lumbricoides/suum in Nothern Europe (Norway, Denmark and Estonia), the study finds that younger men exposed to Ascaris had a striking reduction in lung function and nearly five times higher odds of having asthma compared to the non-exposed.
