Making tau amyloid models in vitro: a crucial and underestimated challenge
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

A Method of Classifying Simple Laced Root Systems [PDF]
A root system in which all roots have same norm is known as a simply laced root system. We present a simple method of classifying all simply laced root systems.

Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms
Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...

Pre-adaptation to anthropogenic disturbance is broadly considered key for plant invasion success. Nevertheless, empirical evidence remains scarce and fragmentary, given the multifaceted nature of anthropogenic disturbance itself and the complexity of ...

Evaluation of Diuretic Activity of Alcoholic Extract of Roots of Cissampelos Pareira in Albino Rats [PDF]
Background: In congestive heart failure, nephritis, toxemia of pregnancy, premenstrual tension and hypertension associated with oedema diuretic compounds are much helpful to relieve these conditions.

Locally Finite Root Supersystems [PDF]
We introduce the notion of locally finite root supersystems as a generalization of both locally finite root systems and generalized root systems. We classify irreducible locally finite root supersystems.

The Syntax of Roots and the Roots of Syntax [PDF]
AbstractThis volume brings together chapters that discuss the nature of roots, the core elements of word meaning. It looks not only at their syntax, but also their phonology, semantics, and morpho-phonological role (or lack thereof), insofar as these do turn out to bear on their interaction with syntax. To what degree these roots carry syntactic and/or

The S1025 peptide is the major antidote to the YrzI toxin, which we renamed here as SpyT (Small Peptide YrzI Toxin) and SpyA (Small Peptide YrzI Antitoxin) (1). Degradation of the toxin–antitoxin spyTA mRNA, either by a translation‐dependent cleavage by the endoribonuclease Rae1 (2) or by direct attack by 3′‐exoribonucleases (3), also contributes to ...

Explicit expressions for real roots of a quartic equation [PDF]
This short article presents explicit expressions for roots of a quartic equation that has all four real roots. Although a general expression for quartic roots is available on Wikipedia, an optimized and slightly shorter expression for only real roots is presented here.

On root frames in $\mathbb{R}^d$ [PDF]
\emph{A root frame} for $\mathbb{R}^d$ is a finite frame whose vectors form a root system. In this note we establish some elementary properties of this class of frames and prove that root frames constitute a subclass of scalable frames. In addition, we show that root frames are examples of a larger class of frames called \emph{eigenframes}.
