Nanoscale gold pillars strengthened through dislocation starvation [PDF]

open access: yes, 2006
It has been known for more than half a century that crystals can be made stronger by introducing defects into them, i.e., by strain-hardening. As the number of defects increases, their movement and multiplication is impeded, thus strengthening the ...

Lipid Catabolism in Starved Yak Is Inhibited by Intravenous Infusion of β-Hydroxybutyrate

open access: yesAnimals, 2020
Lipid is the chief energy source for starved animals. β-hydroxybutyrate (BHBA) is the main ketone body produced by lipid decomposition. In Chinese hamster ovary (CHO) cell experiment, it was found that BHBA could be used not only as an energy ...

Polyphosphate granule biogenesis is temporally and functionally tied to cell cycle exit during starvation in Pseudomonas aeruginosa [PDF]

open access: yes, 2017
Polyphosphate (polyP) granule biogenesis is an ancient and ubiquitous starvation response in bacteria. Although the ability to make polyP is important for survival during quiescence and resistance to diverse environmental stresses, granule genesis is ...

Effects of Starvation on the Physiology and Liver Transcriptome of Yellowcheek (Elopichthys bambusa)

open access: yesFishes, 2023
Anthropogenic and extreme climate disasters cause ecological changes in natural rivers and lakes, increasing the risk of starvation in yellowcheek (Elopichthys bambusa).

Autophagy processes are dependent on EGF receptor signaling [PDF]

open access: yes, 2018
Autophagy is a not well-understood conserved mechanism activated during nutritional deprivation in order to maintain cellular homeostasis. In the present study, we investigated the correlations between autophagy, apoptosis and the MAPK pathways in ...

Proteomic Study of Mitochondria-Associated Endoplasmic Reticulum in Saccharomyces cerevisiae under Different Nutritional Conditions

open access: yesZhipu Xuebao
The mitochondrial-associated endoplasmic reticulum membrane (MAM) is an essential component of eukaryotic cells. It is involved in many critical cellular functions, such as bioenergetics, mitophagy, apoptosis, and calcium signaling, regulating cellular ...

The Metabolic Regulation of Amino Acid Synthesis Counteracts Reactive Nitrogen Stress via Aspergillus nidulans Cross-Pathway Control

open access: yesJournal of Fungi
Nitric oxide (NO) is a natural reactive nitrogen species (RNS) that alters proteins, DNA, and lipids and damages biological activities. Although microorganisms respond to and detoxify NO, the regulation of the cellular metabolic mechanisms that cause ...

Starvation Stress Causes Body Color Change and Pigment Degradation in Acyrthosiphon pisum

open access: yesFrontiers in Physiology, 2019
The pea aphid, Acyrthosiphon pisum (Harris), shows body color shifting from red to pale under starvation in laboratory conditions. These body color changes reflect aphid’s adaptation to environmental stress. To understand the color-shifting patterns, the

A Model Construction of Starvation Induces Hepatic Steatosis and Transcriptome Analysis in Zebrafish Larvae

open access: yesBiology, 2021
Hepatic steatosis caused by starvation, resulting in non-alcoholic fatty liver disease (NAFLD), has been a research topic of human clinical and animal experiments.
