Regulation of vacuolar H+-ATPase activity by the Cdc42 effector Ste20 in Saccharomyces cerevisiae [PDF]

open access: yes, 2012
In the budding yeast Saccharomyces cerevisiae, the Cdc42 effector Ste20 plays a crucial role in the regulation of filamentous growth, a response to nutrient limitation.

Cytoplasmic streaming in plant cells: the role of wall slip

open access: yes, 2012
We present a computer simulation study, via lattice Boltzmann simulations, of a microscopic model for cytoplasmic streaming in algal cells such as those of Chara corallina.

The role of Lambda in the cosmological lens equation [PDF]

open access: yes, 2008
The cosmological constant Lambda affects cosmological gravitational lensing. Effects due to Lambda can be studied in the framework of the Schwarzschild-de Sitter spacetime.

Ciliados (Protozoa) de sedimentos secos de una charca temporaria de la Argentina [PDF]

open access: yes, 2009
Temporary ponds represent special environments that are inhabited by organisms adapted to changing environmental conditions. Ciliates are able to survive complete loss of water in these transient habitats through cyst formation. Nevertheless, ciliates

On lensing by a cosmological constant

open access: yes, 2009
Several recent papers have suggested that the cosmological constant Lambda directly influences the gravitational deflection of light. We place this problem in a cosmological context, deriving an expression for the linear potentials which control the ...

Toxoplasma effectors targeting host signaling and transcription [PDF]

open access: yes, 2017
Early electron microscopy studies revealed the elaborate cellular features that define the unique adaptations of apicomplexan parasites. Among these were bulbous rhoptry (ROP) organelles and small, dense granules (GRAs), both of which are secreted during

Targeting the hard to reach: Challenges and novel strategies in the treatment of intracellular bacterial infections: Targeting intracellular bacteria [PDF]

open access: yes, 2016
Infectious diseases continue to threaten human and animal health and welfare globally, impacting millions of lives and causing substantial economic loss. The use of antibacterials has been only partially successful in reducing disease impact.

Pathogen-host reorganization during Chlamydia invasion revealed by cryo-electron tomography [PDF]

open access: yes, 2014
Invasion of host cells is a key early event during bacterial infection, but the underlying pathogen-host interactions are yet to be fully visualised in three-dimensional detail.

Toxoplasma gondii Syntaxin 6 is required for vesicular transport between endosomal-like compartments and the Golgi Complex [PDF]

open access: yes, 2013
Apicomplexans are obligate intracellular parasites that invade the host cell in an active process that relies on unique secretory organelles (micronemes, rhoptries and dense granules) localized at the apical tip of these highly polarized eukaryotes ...
