The effects of cracks on the movement of Ca+2 within gold refining residue [PDF]

, 1997
Gold refining residue is alkaline (pH> 9), saline (EC1:5: 800- 1100 mS/m) and sodic (ESP>60) (Ho et al., 1998). These chemical properties have a detrimental effect on residue physical properties (hydraulic conductivity, bulk density, porosity).

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Setting of Maximum Residue Limits (MRLs) for Pesticides in Foods

YAKUGAKU ZASSHI
Under the Food Sanitation Law, standards for the production and specifications of food ingredients for distribution may be established. Food that does not meet these standards is prohibited from being distributed. For pesticide residues in food, maximum residue limits (MRLs) are set for each pesticide and food type.

Targeted review of maximum residue levels (MRLs) for profenofos

, 2023
In accordance with Article 43 of Regulation (EC) 396/2005, EFSA received a request from the European Commission to review the existing maximum residue levels (MRLs) for the non‐approved active substance profenofos in view of the possible lowering of the ...

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

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 ...

Determination of proposed maximum residue limit of cypermethrin in starfruit (Averrhoa carambola)

, 2012
Residue trials of cypermethrin in starfruit (Averrhoa carambola) were conducted to estimate the maximum residue limit (MRL). Five trials were conducted at two commercial growers\u27 plots in Mantin, Negeri Sembilan.

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 ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

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 ...

Mathematical Expansion of the Tenson Limit Equation: Asymptotic Completeness and Information Residue Stability [PDF]

This paper develops a rigorous mathematical formulation of the Tenson Limit Equation, extending the original Tenson Equation ∇·(E + iI) = 0 by incorporating G¨ odel’s incompleteness theorem as an information residue term.
