CRISPR Interference of a Clonally Variant GC-Rich Noncoding RNA Family Leads to General Repression of var Genes in Plasmodium falciparum

open access: yesmBio, 2020
The human malaria parasite Plasmodium falciparum uses mutually exclusive expression of the PfEMP1-encoding var gene family to evade the host immune system. Despite progress in the molecular understanding of the default silencing mechanism, the activation

Elastic Interactions of Cells

open access: yes, 2002
Biological cells in soft materials can be modeled as anisotropic force contraction dipoles. The corresponding elastic interaction potentials are long-ranged ($\sim 1/r^3$ with distance $r$) and depend sensitively on elastic constants, geometry and ...

Interaction Proteomics

open access: yesBioscience Reports, 2005
The term proteome is traditionally associated with the identification of a large number of proteins within complex mixtures originating from a given organelle, cell or even organism. Current proteome investigations are basically focused on two major areas, expression proteomics and functional proteomics.

Calcium regulates the mycophagous ability of Burkholderia gladioli strain NGJ1 in a type III secretion system-dependent manner

open access: yesBMC Microbiology, 2020
Background A rice associated bacterium Burkholderia gladioli strain NGJ1 demonstrates mycophagy, a phenomenon wherein bacteria feed on fungi. Previously, we have reported that NGJ1 utilizes type III secretion system (T3SS) to deliver a prophage tail-like

Towards a refined classification of class I dithiol glutaredoxins from poplar: biochemical basis for the definition of two subclasses

open access: yesFrontiers in Plant Science, 2013
Glutaredoxins (Grxs) are small oxidoreductases particularly specialized in the reduction of protein-glutathione adducts. Compared to other eukaryotic organisms, higher plants present an increased diversity of Grxs which are organized into four classes ...

Flavor Changing Scalar Interactions

open access: yes, 1993
The smallness of fermion masses and mixing angles has recently been been attributed to approximate global $U(1)$ symmetries, one for each fermion type.

Neutrino interactions with nuclei

open access: yes, 2009
We present a model for neutrino-nucleus scattering in the energy region relevant for present and forthcoming neutrino-oscillation experiments. The model is based on the RPA treatment of the nuclear responses in the quasi-elastic and Delta-resonance ...

Neutrino Interactions in Matter :

open access: yes, 1993
If a fermion is travelling through a medium, it can have matter-induced magnetic and electric dipole moments. These contributions conserve chirality, and can be non-vanishing even for a Majorana neutrino.

Interaction Grammars [PDF]

open access: yesProceedings of the 18th conference on Computational linguistics -, 2000
Interaction Grammars (IG) are a new linguistic formalism which is based on descriptions of under-specified trees in the framework of intuitionistic linear logic (ILL). Syntactic composition, which is expressed by deduction in linear logic, is controlled by a system of polarized features.
