FEBS Letters, EarlyView.Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Contribution to evaluation of mechanical properties during impact loading [PDF]
Metalurgija, 2008 The paper analyzes the influence of the impact rate of up to 120 ms-1 with a constant energy on the relative compression of high-grade unalloyed steels, Cu and Zn, and the evaluation of energy consumed during the impact bending test at the impact rate of

Measurements of Strain-Rate Distributions on Material After Shpb Impact
Engineering Transactions, 2014 We have proposed a sophisticated novel method of the SHPB experiment to measure the local strain-rate distributions on a surface of the specimen by using mechanoluminescent materials combined with a high-speed camera and an image intensifier.

Effects of Heating Rate and Strain Rate on Phase Transformation in Micro-Grinding [PDF]
EPJ Web of Conferences, 2019 The phase transformation in the grinding process could have a significant impact on the processing performance of the products. Although grinding process can lead to high heating and strain rates, the current studies on the phase transformation typically

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

The microbiome in human skin aging
FEBS Letters, EarlyView.Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Strain-Rate and Stress-Rate Models of Nonlinear Viscoelastic Materials
MathematicsThe paper is devoted to the modeling of nonlinear viscoelastic materials. The constitutive equations are considered in differential form via relations between strain, stress, and their derivatives in the Lagrangian description.

High strain rate behaviour of polypropylene microfoams
EPJ Web of Conferences, 2012 Microcellular materials such as polypropylene foams are often used in protective applications and passive safety for packaging (electronic components, aeronautical structures, food, etc.) or personal safety (helmets, knee-pads, etc.).

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
