Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Buckling of a beam extruded into highly viscous fluid
, 2014 Inspired by microscopic paramecies which use trichocyst extrusion to propel themselves away from thermal aggressions, we propose a macroscopic experiment to study the stability of a slender beam extruded in a highly viscous fluid.

Biological Sciences in Space, 1988 This review briefly describes four physical and two physiological hypotheses that have been proposed on the mechanism of negative gravitaxis or geotaxis of Paramecium. In the hydrostatic hypothesis (Verworn, 1889), the density of the rear part of Paramecium is greater than that of the rest of the organism so that the body axis is tilted anterior upward

Ecography, Volume 2025, Issue 5, May 2025.Biotic interactions play a fundamental role in shaping multitrophic species communities, yet incorporating these interactions into species distribution models (SDMs) remains challenging. With the growing availability of species interaction networks, it is now feasible to integrate these interactions into SDMs for more comprehensive predictions.

Gravitaxis of asymmetric self-propelled colloidal particles [PDF]
, 2014 Many motile microorganisms adjust their swimming motion relative to the gravitational field and thus counteract sedimentation to the ground. This gravitactic behavior is often the result of an inhomogeneous mass distribution which aligns the ...

Where is Memory Information Stored in the Brain? [PDF]
arXiv, 2021 Within the scientific research community, memory information in the brain is commonly believed to be stored in the synapse - a hypothesis famously attributed to psychologist Donald Hebb. However, there is a growing minority who postulate that memory is stored inside the neuron at the molecular (RNA or DNA) level - an alternative postulation known as ...

Folia Biologica, 2005 New stands of rare species of the Paramecium aurelia complex were found in Europe, i.e. P. pentaurelia and P. dodecaurelia in Italy and P. septaurelia in Germany. The species were identified by mating reactions with the standard strains of each species.

Algal Symbiont Diversity and Host Fitness Variation in Amoebozoan Photosymbiosis
Journal of Eukaryotic Microbiology, Volume 72, Issue 3, May/June 2025.ABSTRACT Photosymbioses, the symbiotic relationships between microalgae and non‐photosynthetic eukaryotes, are sporadically found in many eukaryotic lineages. Only a few taxa, such as cnidarians and ciliates hosting algal endosymbionts, have been actively studied, which has hindered understanding the universal mechanisms of photosymbiosis establishment.

Development of Antisense Tools to Study Bodo saltans and Its Intracellular Symbiont
MicrobiologyOpen, Volume 14, Issue 2, April 2025.Obligate symbioses present challenges for functional genetic analysis. This study shows that antisense inhibition cannot be used to investigate gene functions in the aquatic symbiosis between Bodo saltans and its bacterial symbiont. Our work stresses the importance of the development of alternative protocols to study the biology of both the ...
