Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms
FEBS Letters, EarlyView.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 ...

Lithium Abundances in the alpha Per Cluster [PDF]
, 2010 Lithium abundances are presented and discussed for 70 members of the 50 Myr old open cluster alpha Per. More than half of the abundances are from new high-resolution spectra. The Li abundance in the F-type stars is equal to its presumed initial abundance confirming previous suggestions that pre-main sequence depletion is ineffective for these stars ...

A note on the abundance conjecture [PDF]
Algebraic Geometry 2 (2015), no. 4, 476-488, 2014 We prove that the abundance conjecture for non-uniruled klt pairs in dimension $n$ implies the abundance conjecture for uniruled klt pairs in dimension $n$, assuming the Minimal Model Program in lower dimensions.

An Abundance of Nodulation Factors [PDF]
Chemistry & Biology, 2005 In this issue of Chemistry & Biology, Morón et al. [1] report that Rhizobium tropici CIAT899 produces different Nod factors in response to flavonoid induction under differing environmental conditions. This unanticipated environmental dependence has implications for altering or potentially improving the host-bacteria interaction in bean nodulation.

FEBS Letters, EarlyView.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 ...

When Youth Dialogue: A Pedagogic Framework for Changing the Conversation About Migration
Global Education Review, 2018 How should educators teach about one of the most complex and pressing issues of our times? This paper presents an empirically-grounded framework to help educators understand the opportunities and challenges of engaging youth around the topic of migration,

Brazilian Journal of BiologyThe study of parasite body size is an important approach to understand the different patterns of helminth community structure, once it is usually analysed using only numerical descriptors which do not capture size heterogeneity among parasite species. In

Role of servitization in transitioning from scarcity to abundance paradigm
Frontiers in Research Metrics and Analytics, 2022 Servitization refers to firms that sell an “outcome-as-a-service”, rather than just a physical product. In this study, we first examine how servitization has enabled companies such as Netflix to disrupt industries and transition from offering finite ...
