Trichinella spiralis: Mere Co-Existence or Carcinogenic Parasite For Oral Squamous Cell Carcinoma? [PDF]

Journal of Clinical and Diagnostic Research, 2015
Trichinella spiralis is a parasite which is usually seen in pork-eaters. Most of the trichinosis infections cause little or no symptoms. We report a rare case of a middle aged North Indian male who presented with a painless ulcer in right buccal mucosa ...

Caenorhabditis elegans as a valuable model for the study of anthelmintic pharmacodynamics and drug-drug interactions: The case of ivermectin and eprinomectin

Frontiers in Pharmacology, 2022
Caenorhabditis elegans is a free-living nematode that has been validated for anthelmintic drug screening. However, this model has not been used to address anthelmintic dose-response-time and drug-drug interactions through matrix array methodology ...

Inhibition of Ferroptosis Delays Aging and Extends Healthspan Across Multiple Species

Advanced Science, EarlyView.
This study identifies ferroptosis as a key driver of cellular senescence, with its inhibition delaying aging and extending healthspan across species. During senescence, ferroptosis worsens, increasing oxidative stress and lipid peroxidation, which accelerate aging.

Coelomocytes: Biology and Possible Immune Functions in Invertebrates with Special Remarks on Nematodes

International Journal of Zoology, 2009
All metazoans are exposed to a wide range of microbes and have evolved complex immune defenses used to repel infectious agents. Coelomocytes play a key role in the defense reactions of most invertebrates.

Multi-environment model estimation for motility analysis of Caenorhabditis Elegans [PDF]

, 2010
The nematode Caenorhabditis elegans is a well-known model organism used to investigate fundamental questions in biology. Motility assays of this small roundworm are designed to study the relationships between genes and behavior. Commonly, motility analysis is used to classify nematode movements and characterize them quantitatively. Over the past years,

Bioinspired Mechanisms and Actuation of Soft Robotic Crawlers

Advanced Science, EarlyView.
Researchers have been developing soft materials and robotic crawlers inspired by soft‐bodied animals to mimic effective crawling in complex environments. This review explores the state‐of‐the‐art in soft crawlers, highlighting the interaction between materials, crawling mechanisms, actuation, and applications. The review concludes by providing insights

Structures and functions of cilia during vertebrate embryo development

Molecular Reproduction and Development, Volume 89, Issue 12, Page 579-596, December 2022., 2022
Abstract Cilia are hair‐like structures that project from the surface of cells. In vertebrates, most cells have an immotile primary cilium that mediates cell signaling, and some specialized cells assemble one or multiple cilia that are motile and beat synchronously to move fluids in one direction.

Pan-phylum In Silico Analyses of Nematode Endocannabinoid Signalling Systems Highlight Novel Opportunities for Parasite Drug Target Discovery

Frontiers in Endocrinology, 2022
The endocannabinoid signalling (ECS) system is a complex lipid signalling pathway that modulates diverse physiological processes in both vertebrate and invertebrate systems.

A CNN Framenwork Based on Line Annotations for Detecting Nematodes in Microscopic Images [PDF]

arXiv, 2020
Plant parasitic nematodes cause damage to crop plants on a global scale. Robust detection on image data is a prerequisite for monitoring such nematodes, as well as for many biological studies involving the nematode C. elegans, a common model organism. Here, we propose a framework for detecting worm-shaped objects in microscopic images that is based on ...

Navigation of C. elegans in three-dimensional media: roll maneuvers and planar turns [PDF]

, 2016
Free-living nematode Caenorhabditis elegans is a powerful genetic model, essential for investigations ranging from behavior to neuroscience to aging, and locomotion is a key observable used in these studies. However, despite the fact that in its natural environment C. elegans moves in three-dimensional (3D) complex media (decomposing organic matter and
