How innate immunity proteins kill bacteria and why they are not prone to resistance [PDF]
, 2017 Recent advances on antibacterial activity of peptidoglycan recognition proteins (PGRPs) offer some insight into how innate immunity has retained its antimicrobial effectiveness for millions of years with no frequent emergence of resistant strains. First,

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

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 ...

Starvation, Stress Resistance, and Cancer
Trends in Endocrinology & Metabolism, 2018 Cancer cells are characterized by dysregulation in signal transduction and metabolic pathways leading to increased glucose uptake, altered mitochondrial function, and the evasion of antigrowth signals. Fasting and fasting-mimicking diets (FMDs) provide a particularly promising intervention to promote differential effects in normal and malignant cells ...

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

Resistance to Epinephrine Stress in the Dog.
Experimental Biology and Medicine, 1950 Summary1. The repetitive daily administration of epinephrine in the dog results in a progressively diminished eosinopenic response.2. During the state of epinephrine resistance, there is neither a depletion of endogenous ACTH nor an exhaustion of the adrenal cortex.3. Adaptation of the organism to epinephrine stress with decreased tissue utilization of

Multiple-stress analysis for isolation of Drosophila longevity genes [PDF]
, 2004 Long-lived organisms tend to be more resistant to various forms of environmental stress. An example is the Drosophila longevity mutant, methuselah, which has enhanced resistance to heat, oxidants, and starvation.

Preference Test of Plutella xylostella Larvae upon DMNT Treatment
Bio-Protocol, 2021 We describe a method to test the preference of insects in response to (3E)-4,8-dimethyl-1,3,7-nonatriene (DMNT). We use a device that includes a horizontal glass tube, two grooves (with activated carbon), air flow, rubber stoppers/tubes, transparent ...
