SpxA1 and SpxA2 act coordinately to fine-tune stress responses and virulence in Streptococcus pyogenes [PDF]

, 2017
SpxA is a unique transcriptional regulator highly conserved among members of the phylum Firmicutes that binds RNA polymerase and can act as an antiactivator. Why some Firmicutes members have two highly similar SpxA paralogs is not understood.

The pathogen Moniliophthora perniciosa promotes differential proteomic modulation of cacao genotypes with contrasting resistance to witches´ broom disease [PDF]

, 2020
Background: Witches' broom disease (WBD) of cacao (Theobroma cacao L.), caused by Moniliophthora perniciosa, is the most important limiting factor for the cacao production in Brazil.

Specificity of resistance to oxidative stress [PDF]

Journal of Neurochemistry, 2002
AbstractTwo clonal nerve‐like cell lines derived from HT22 and PC12 have been selected for resistance to glutamate toxicity and amyloid toxicity, respectively. In the following experiments it was asked if these cell lines show cross‐resistance toward amyloid beta peptide (Aβ) and glutamate as well as toward a variety of additional neurotoxins ...

Use of elastic stability analysis to explain the stress-dependent nature of soil strength [PDF]

, 2015
The peak and critical state strengths of sands are linearly related to the stress level, just as the frictional resistance to sliding along an interface is related to the normal force. The analogy with frictional sliding has led to the use of a ‘friction

The neurobiology of the stress-resistant brain [PDF]

Stress, 2011
The 2010 Neurobiology of Stress Workshop brought together scientists from all over the world to share and discuss their results from studies examining the consequences of acute, repeated, and chronic stressor exposure on health and disease. Session IV entitled "The neurobiology of the stress-resistant brain" explored how we can intervene to promote ...

Environmental stress responses in Lactococcus lactis [PDF]

, 1999
Bacteria can encounter a variety of physical conditions during their life. Bacterial cells are able to survive these (often adverse) conditions by the induction of specific or general protection mechanisms. The lactic acid bacterium Lactococcus lactis is

Screening for stress-resistance mutations in the mouse [PDF]

Frontiers in Genetics, 2014
Longevity is correlated with stress resistance in many animal models. However, previous efforts through the boosting of the antioxidant defense system did not extend life span, suggesting that longevity related stress resistance is mediated by other uncharacterized pathways.

Comparative transcriptome analysis reveals important roles of nonadditive genes in maize hybrid An’nong 591 under heat stress

BMC Plant Biology, 2019
Background Heterosis is the superior performance of F1 hybrids relative to their parental lines for a wide range of traits. In this study, expression profiling and heterosis associated genes were analyzed by RNA sequencing (RNA-Seq) in seedlings of the ...

Ab initio and finite-temperature molecular dynamics studies of lattice resistance in tantalum [PDF]

, 2002
This manuscript explores the apparent discrepancy between experimental data and theoretical calculations of the lattice resistance of bcc tantalum. We present the first results for the temperature dependence of the Peierls stress in this system and the ...

Insulin resistance and surgical stress [PDF]

Medicinski podmladak, 2016
Surgical procedures are associated with stress reaction, that leads to inflammation and insulin resistance. Insulin resistance is protective mechanism developed in postoperative period, in order to protect sources of carbohydrate for glucose-dependent organs, such as brain.
