Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

Animal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Computer simulation of protein systems [PDF]

, 1984
Ligand binding to dihydrofolate reductase (DHFR) is discussed. This is an extremely important enzyme, as it is the target of several drugs (inhibitors) which are used clinically as antibacterials, antiprotozoals and in cancer chemotherapy. DHFR catalyzes

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Soluble oligomerization provides a beneficial fitness effect on destabilizing mutations

, 2012
Mutations create the genetic diversity on which selective pressures can act, yet also create structural instability in proteins. How, then, is it possible for organisms to ameliorate mutation-induced perturbations of protein stability while maintaining ...

The Plasmodium falciparum, Nima-related kinase Pfnek-4: a marker for asexual parasites committed to sexual differentiation [PDF]

, 2012
<b>Background</b> Malaria parasites undergo, in the vertebrate host, a developmental switch from asexual replication to sexual differentiation leading to the formation of gametocytes, the only form able to survive in the mosquito vector ...

Vibrational Structure of Dihydrofolate Bound to R67 Dihydrofolate Reductase [PDF]

Journal of Biological Chemistry, 2001
R67 is a Type II dihydrofolate reductase (DHFR) that catalyzes the reduction of dihydrofolate (DHF) to tetrahydrofolate by facilitating the addition of a proton to N5 of DHF and the transfer of a hydride ion from NADPH to C6. Because this enzyme is a plasmid-encoded DHFR from trimethoprim-resistant bacteria, extensive studies on R67 with various ...

Green Synthesis of ZnO Nanoparticles From Spirulina platensis: Antimicrobial and Cytotoxic Evaluation With Molecular Docking Studies

ChemistryOpen, EarlyView.
Algal‐extract‐derived ZnO nanoparticles show shape anisotropy and are bio capped by phytochemicals. These green‐synthesized NPs strongly inhibit S. aureus and K. pneumoniae biofilms. Molecular docking suggests stable binding of surface biomolecules to microbial targets, highlighting synergistic antibacterial mechanisms.

Antimalarial flavonoid glycoside from Carica papaya with inhibitory potential against Plasmodium falciparum dihydrofolate reductase thymidylate synthase: an in-silico study

Universa Medicina
BACKGROUND Carica papaya is traditionally used to treat malaria. The mechanism of action of the active constituents may be determined by molecular docking.
