PDMS filter structures for size-dependent larval sorting and on-chip egg extraction of C. elegans

Martinus Gijs, Hüseyin Baris Atakan, Furkan Ayhan

C. elegans-based assays require age-synchronized populations prior to experimentation to achieve standardized sets of worm populations, due to which age-induced heterogeneous phenotyping effects can be avoided. There have been several approaches to synchro ...

Extending the Concept of Predicting Fish Acute Toxicity In Vitro to the Intestinal Cell Line RTgutGC

Kristin Schirmer, Hannah Inka Schug, Jenny Maner

Testing chemicals for fish acute toxicity is a legal requirement in many countries as part of environmental risk assessment. To reduce the number of fish used, substantial efforts have been focused on alternative approaches. Prominently, the cell viability ...

Remodeling of peripheral nerve ensheathment during the larval-to-adult transition in Drosophila

Soumya Banerjee, Kumar Vishal

Over the course of a 4-day period of metamorphosis, the Drosophila larval nervous system is remodeled to prepare for adult-specific behaviors. One example is the reorganization of peripheral nerves in the abdomen, where five pairs of abdominal nerves (A4-A ...

Scleractinian coral morphogenesis : searching for stem cells and precursors of the skeletogenic calicodermis

Agathe Eliette Marie Lecointe

Metamorphosis is a crucial step in the life cycle of a scleractinian coral: The swimming coral larva, the planula, settles, and metamorphoses into a sessile calcifying primary polyp, which subsequently grows into an adult colony. Importantly, morphogenesis ...

Oral transfer of chemical cues, growth proteins and hormones in social insects

Laure Menin, Oksana Riba Grognuz, Daniel Ortiz Trujillo, Laurent Keller

Social insects frequently engage in oral fluid exchange trophallaxis between adults, and between adults and larvae. Although trophallaxis is widely considered a food-sharing mechanism, we hypothesized that endogenous components of this fluid might underlie ...

dHb9 Expressing Larval Motor Neurons Persist Through Metamorphosis to Innervate Adult-Specific Muscle Targets and Function in Drosophila Eclosion

Soumya Banerjee

The Drosophila larval nervous system is radically restructured during metamorphosis to produce adult specific neural circuits and behaviors. Genesis of new neurons, death of larval neurons and remodeling of those neurons that persistent collectively act to ...

Silver nanoparticles inhibit fish gill cell proliferation in protein-free culture medium

Kristin Schirmer, Laura Sigg, Renata Behra, Yang Yue

While short-term exposures of vertebrate cells, such as from fish, can be performed in defined, serum-free media, long-term cultures generally require addition of growth factors and proteins, normally supplied with a serum supplement. However, proteins are ...

From Embryo to Adult: Hematopoiesis along the Drosophila Life Cycle

Bruno Lemaitre, Elodie Julie Virginie Ramond

Studies on Drosophila hematopoiesis have thus far focused on the embryonic and larval origin of hemocytes, the fly blood cells. In this issue of Developmental Cell, Ghosh et al. (2015) identify adult hematopoietic hubs containing progenitors that can diffe ...

Toxicity of silver nanoparticles to a fish gill cell line: Role of medium composition

Kristin Schirmer, Laura Sigg, Renata Behra, Yang Yue

In aqueous solutions, silver nanoparticle (AgNP) behavior is affected by a variety of factors which lead to altered AgNP size and toxicity. Our research aims to explore the effect of media composition on citrate-coated AgNP (cit-AgNP) behavior and toxicity ...

Inverse kinematics and reflex based controller for body-limb coordination of a salamander-like robot walking on uneven terrain

Auke Ijspeert, Kamilo Andres Melo Becerra, Tomislav Horvat, Robin Thandiackal, Konstantinos Karakasiliotis, Laura Deanne Fleury

Search and rescue (SAR) missions are being carried out by several types of robots. They include ground, marine and air vehicles depending on the terrain and mission to be tackled. A particular niche for SAR activities are shallow waters. They present high ...

Biomimetic Pieris rapae’s Nanostructure and Its Use as a Simple Sucrose Sensor

Philippe Renaud, David Vincent Bonzon, Rodrigo Martinez Duarte

iomimetics often provides efficient ways to create a product incorporating novel properties. Here we present the replication of the Pieris rapae butterfly optical structure. This butterfly has white wings with black spots. The white coloration is produced ...
