Flagellar membrane association via interaction with lipid rafts [PDF]

open access: yes, 2009
The eukaryotic flagellar membrane has a distinct composition from other domains of the plasmalemma. Our work shows that the specialized composition of the trypanosome flagellar membrane reflects increased concentrations of sterols and saturated fatty ...

Engineering Bacterial Secretion Systems for Enhanced Tumor Imaging and Surgical Guidance

open access: yesAdvanced Materials, EarlyView.
This study presents a novel contrast agent platform, Streptavidin Associated Salmonella (SAS), for fluorescence image guided surgery. SAS selectively colonizes tumors and secretes streptavidin, enabling precise delineation of invasive tumor margins with prolonged signal retention.

Scanning Electron Microscopy of the Rainbow Trout (Salmo gairdneri Richardson) Spermatozoon [PDF]

open access: yes, 1976
The scanning electron microscope was used to determine the morphology of the rainbow trout (Salmo gairdneri Richardson) spermatozoon. The spermatozoon is approximately 32 μm long and consists of a head, mitochondrial collar, and flagellum.

Cell body rocking is a dominant mechanism for flagellar synchronization in a swimming alga

open access: yes, 2013
The unicellular green algae Chlamydomonas swims with two flagella, which can synchronize their beat. Synchronized beating is required to swim both fast and straight.

Escherichia coli EHEC Germany outbreak preliminary functional annotation using BG7 system [PDF]

open access: yes, 2011
We have annotated the European outbreak E. coli EHEC genome sequenced by BGI (6-2-2011) and assembled with MIRA by Nick Loman (6-2-2011 ). Our system BG7, Bacterial Genome annotation of Era7 Bioinformatics, predicts ORFs and annotates them based on ...

A Flagellum-specific Calcium Sensor

open access: yesJournal of Biological Chemistry, 2005
The flagellar calcium-binding protein (FCaBP) of the flagellated protozoan Trypanosoma cruzi associates with the flagellar membrane via its N-terminal myristate and palmitate moieties in a calcium-modulated, conformation-dependent manner. This mechanism of localization is similar to that described for neuronal calcium sensors, which undergo calcium ...

Bacterial‐Based Molecular Communication: Simulation of a Fixed and Receding Receiver Scenarios in Varied Viscosities and Environmental Conditions

open access: yesAdvanced Theory and Simulations, EarlyView.
This study presents a robust 3D simulation for BBMC, focusing on both fixed and receding receiver scenarios across various conditions. Key parameters such as D, Q, u, and d are tested at different values to assess the performance and reliability of BBMC in applications like drug delivery, addressing critical challenges in nanoscale communication with ...

The ATM Kinase Inhibitor AZD0156 Is a Potent Inhibitor of Plasmodium Phosphatidylinositol 4‐Kinase (PI4Kβ) and Is an Attractive Candidate for Medicinal Chemistry Optimization Against Malaria

open access: yesAngewandte Chemie, EarlyView.
AZD0156, an ATM kinase inhibitor in clinical development, shows promising multistage antiplasmodial activity by targeting Plasmodium falciparum phosphatidylinositol 4‐kinase (PfPI4Kβ). With an improved specificity profile relative to other PfPI4Kβ inhibitors and moderate efficacy in a P.

Localized Activation of Bending in Proximal, Medial and Distal Regions of Sea-Urchin Sperm Flagella [PDF]

open access: yes, 1973
Spermatozoa from the sea urchin, Colobocentrotus atratus, were partially demembranated by extraction with solutions containing Triton X-100 at a concentration which was insufficient to solubilize the membranes completely.

Modelling the Mechanics and Hydrodynamics of Swimming E. coli

open access: yes, 2015
The swimming properties of an E. coli-type model bacterium are investigated by mesoscale hy- drodynamic simulations, combining molecular dynamics simulations of the bacterium with the multiparticle particle collision dynamics method for the embedding ...
