Stratification of centrifuged amoeba nuclei investigated by electron microscopy [PDF]

open access: yes, 1968
Study establishes a relationship between radioresistance and the nucleolar stratification characteristics of various amoeba species. Two species of fresh water amoeba are studied with the electron microscope.

Short-Range Structural Transformations in Water at High Pressures

open access: yes, 2011
We report results of molecular dynamics simulations of liquid water at the temperature T=277 K for a range of high pressure. One aim of the study was to test the model Amoeba potential for description of equilibrium structural properties and dynamical ...

Analytic varieties with finite volume amoebas are algebraic [PDF]

open access: yes, 2011
In this paper, we study the amoeba volume of a given $k-$dimensional generic analytic variety $V$ of the complex algebraic torus $(\C^*)^n$. When $n\geq 2k$, we show that $V$ is algebraic if and only if the volume of its amoeba is finite. In this precise

Molecular Simulations of Polymer‐based Drug Nanocarriers: From Physical and Structural Properties to Controlled Release

open access: yesAdvanced Healthcare Materials, EarlyView.
Polymer‐based drug delivery systems can effectively overcome the limitations of free drugs in terms of solubility, stability, and plasma half‐life, yet their development has traditionally relied on time‐consuming trial‐and‐error approaches. This review highlights recent advances in applying molecular simulation to the design of polymer‐based drug ...

Giant Virus-Eukaryote Interactions as Ecological and Evolutionary Driving Forces

open access: yesmSystems, 2021
Giant DNA viruses of eukaryotes are notable for their extraordinary genome size and coding capacity. Once thought to be oddities in the virus world, these elusive microbes have turned out to be widely occurring in marine, freshwater, and terrestrial ...

Marine Bacteria Display Different Escape Mechanisms When Facing Their Protozoan Predators

open access: yesMicroorganisms, 2020
Free-living amoeba are members of microbial communities such as biofilms in terrestrial, fresh, and marine habitats. Although they are known to live in close association with bacteria in many ecosystems such as biofilms, they are considered to be major ...

The Moduli Space of Harnack Curves in Toric Surfaces

open access: yes, 2020
In 2006, Kenyon and Okounkov computed the moduli space of Harnack curves of degree $d$ in $\mathbb{C}\mathbb{P}^2$. We generalize to any projective toric surface some of the techniques used there. More precisely, we show that the moduli space $\mathcal{H}

Identification of Naegleria fowleri proteins linked to primary amoebic meningoencephalitis [PDF]

open access: yes, 2017
Naegleria fowleri (N. fowleri) causes primary amoebic meningoencephalitis, a rapidly fatal disease of the central nervous system. N. fowleri can exist in cyst, flagellate or amoebic forms, depending on environmental conditions.
