Digging in sand crabs: coordination of joints in individual legs.
Sand crabs use their multi-jointed legs to dig into sand. Combined movement and electromyogram (EMG) analyses showed that the pattern of intra-leg coordination in the legs of two sand crabs of different families (Blepharipoda occidentalis and Emerita analoga) is similar in legs 2 and 3, but very different in leg 4. For example, the sequence of proximal joint movements in legs 2 and 3 is elevati...
متن کاملDigging Deeper Into Hepatitis C Virus Outbreaks
Methods for investigating outbreaks of hepatitis C virus (HCV) have evolved since the discovery of the virus in 1989. Early investigations focused on epidemiological evidence such as likelihood of exposure, risk factors, temporal information, and serological evidence to identify members of an outbreak [1–3]. Streamlined nucleic acid sequencing methods provided an important means of verifying su...
متن کاملHemograms and myelograms of healthy female mice of C-57 brown and CFW strains.
I N the course of quantitative studies of experimental blood dyscrasias in laboratory mice, two inbred strains of mice were studied to establish normal values in young adult females. The data include mean and standard deviations of leucocyte count, differential count, erythrocyte count, hemoglobin and hematocrit determinations, and reticulocyte count of peripheral blood; differential count of m...
متن کاملNematodes Infect, But Do Not Manipulate Digging By, Sand Crabs, Lepidopa benedicti
We examined sand crabs (Lepidopa benedicti) for endoparasites, and found the only parasite consistently infecting the studied population were small nematodes. Because many nematodes have complex life cycles involving multiple hosts, often strongly manipulating their hosts, we hypothesized that nematodes alter the behavior of their sand crab hosts. We predicted that more heavily infected crabs w...
متن کاملHEMATOPOIESIS Increased Fetal and Extramedullary Hematopoiesis in Fas - Deficient C 57 BL / 6 - lpr / lpr Mice
In this study, we examined the consequences of Fas deficiency on hematopoiesis in C57BL/6-lpr/lpr mice. We found a striking extramedullary increase in hematopoietic progenitor cells, comprising erythroid and nonerythroid lineages alike. These modifications preceded the lymphadenopathy, because early progenitors (colony-forming units-spleen [CFUS] day 8) were already augmented in day-18 fetal li...
