Evaluation of ruminal outflow of protein and nitrogen fractions, and total and individual essential amino acid predictions, by nutritional models in dairy cattle

Journal of Dairy Science
: The objective was to evaluate the fit statistics for the predictions of ruminal outflow of protein fractions and EAA by the NRC, National Academies of Sciences, Engineering, and Medicine (NASEM), Cornell Net Carbohydrate and Protein System (CNCPS), and

Amino acid nutrition of dairy cows: invited review [PDF]

Animal Bioscience
Improving nitrogen (N) efficiency in dairy production systems is important due to environmental concerns and the economic cost of dietary protein. A substantial proportion of dietary N consumed by lactating dairy cows is not converted into milk protein ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Effects of reduced metabolizable protein diets supplemented with rumen-protected His under adequate Met and Lys supply on production, nutrient digestibility, N utilization, and manure ammonia emissions in lactating cows

Journal of Dairy Science
: Balancing for limiting AA may prevent reduced production when deficient MP is provided. The objective of the study was to determine the effects of rumen-protected (RP) His supplementation at different levels of MP when Lys and Met supplies meet the ...

Exogenous addition of histidine reduces copper availability in the yeast Saccharomyces cerevisiae

, 2014
The basic amino acid histidine inhibited yeast cell growth more severely than lysine and arginine. Overexpression of CTR1, which encodes a high-affinity copper transporter on the plasma membrane, or addition of copper to the medium alleviated this ...

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Histidine Metabolic Pathway Modifies the Relationships Between 6:2 Cl-PFESA Exposure and Preterm Birth

Toxics
Background: Evidence linking chlorinated polyfluoroalkyl ether sulfonic acids (Cl-PFESAs) to preterm birth (PTB) is limited, and their relationships with the metabolome remain unexplored. Aims: Our study aimed to explore the role of the metabolome in the

Carboplatin binding to histidine [PDF]

Acta Crystallographica Section F Structural Biology Communications, 2014
Carboplatin is a second-generation platinum anticancer agent used for the treatment of a variety of cancers. Previous X-ray crystallographic studies of carboplatin binding to histidine (in hen egg-white lysozyme; HEWL) showed the partial conversion of carboplatin to cisplatin owing to the high NaCl concentration used in the crystallization conditions ...

Histidine limitation alters plant development and influences the TOR network [PDF]

Plant growth depends on growth regulators, nutrient availability, and amino acid levels, all of which influence cell wall formation and cell expansion. Cell wall integrity and structures are surveyed and modified by a complex array of cell wall integrity

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.
