Intermediate scattering function of an anisotropic active Brownian particle [PDF]

Scientific Reports 6, 36702 (2016), 2017
Various challenges are faced when animalcules such as bacteria, protozoa, algae, or sperms move autonomously in aqueous media at low Reynolds number. These active agents are subject to strong stochastic fluctuations, that compete with the directed motion.

The phagotrophic origin of eukaryotes and phylogenetic classification of Protozoa.

International Journal of Systematic and Evolutionary Microbiology, 2002
Eukaryotes and archaebacteria form the clade neomura and are sisters, as shown decisively by genes fragmented only in archaebacteria and by many sequence trees. This sisterhood refutes all theories that eukaryotes originated by merging an archaebacterium

Time‐Dependent Effect of Prophylactic Trimethoprim‐Sulfamethoxazole on the Incidence of Serious Infections in Antineutrophil Cytoplasmic Antibody–Associated Vasculitis: A Target Trial Emulation Study

Arthritis &Rheumatology, EarlyView.
Objective The objective of this study was to investigate the effect of prophylactic trimethoprim‐sulfamethoxazole (TMP‐SMX) on the incidence of serious infections in patients with antineutrophil cytoplasmic antibody–associated vasculitis (AAV). Methods This multicenter cohort study was designed to emulate a target trial that studied 296 patients with ...

Eukaryotic swimming cells are shaped by hydrodynamic constraints [PDF]

arXiv, 2023
Eukaryotic swimming cells such as spermatozoa, algae or protozoa use flagella or cilia to move in viscous fluids. The motion of their flexible appendages in the surrounding fluid induces propulsive forces that balance with the viscous drag on the cells and lead to a directed swimming motion.

Effects of macauba cake on profile of rumen protozoa of lambs

, 2017
The present study was conducted to determine the effects of the inclusion of macauba cake, from biodiesel processing, on profile of rumen protozoa of Santa Ines lambs. Twenty-four lambs were randomized in block design supplemented with macauba cake at 0,

Influence of rumen protozoa on methane emission in ruminants: a meta-analysis approach.

Animal, 2014
A meta-analysis was conducted to evaluate the effects of protozoa concentration on methane emission from ruminants. A database was built from 59 publications reporting data from 76 in vivo experiments.

Green Propolis Extract‐Mediated Synthesis of Biogenic Silver Nanoparticles: In Vitro Antileishmanial and Antibacterial Activities, Cytotoxicity and Ex Vivo Irritation Testing

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study describes the green synthesis, characterization, and biological evaluation of silver nanoparticles (AgNPs) obtained from green propolis (AgNPs‐PRO). Before nanoparticles synthesis, a hydroethanolic green propolis extract (GPE) was obtained through ultrasound‐assisted extraction and characterized by high‐performance liquid ...

Construction of luciferase-expressing Neospora caninum and drug screening

Parasites & Vectors
Background Neospora caninum is an apicomplexan parasite that is particularly responsible for abortions in cattle and neuromuscular disease in dogs. Due to the limited effectiveness of currently available drugs, there is an urgent need for new therapeutic

Effect of progressive inoculation of fauna-free sheep with holotrich protozoa and total-fauna on rumen fermentation, microbial diversity and methane emissions

FEMS Microbiology Ecology, 2014
Rumen methanogenesis represents an energy waste for the ruminant and an important source of greenhouse gas; thus, integrated studies are needed to fully understand this process.

Evaluation of Polar Substituted Schiff Bases and 1,2,3‐Triazole Hybrids as Anticancer Agents

Chemistry &Biodiversity, EarlyView.
ABSTRACT Polar substituted Schiff bases and 1,2,3‐triazole hybrids (2–6) were successfully synthesized by Schiff base condensation reaction between the previously synthesized triazole 1 and series of polar substituted amines. The chemical structures of the hybrids were confirmed using spectroscopies (NMR and FTIR), CHN elemental analysis and single ...
