Alternative Approaches and Plant‐Based Remedies for Livestock Health Management Among the Batswana of Southern Africa: A Review

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
ABSTRACT Due to limited access to, and the high cost of conventional veterinary services, Batswana communities often rely on ethnoveterinary practices for livestock health management. This review provides an in‐depth analysis on the ethnoveterinary uses, biological properties and safety assessment of plants utilised in livestock husbandry. A systematic

Making Blank Faces Expressive: Chemical Approaches to the Modification of Chemically Inert Peptides

open access: yesJournal of Peptide Science, Volume 32, Issue 3, March 2026.
As an alternative to the conventional approach, which combines amino acid monomers in a one‐by‐one fashion to peptide derivatives, the chemical modification of existing peptides has attracted significant attention in recent years. However, such approaches generally target the reactive functional groups in cysteine and lysine residues, particularly in ...

Treatment of pediatric epilepsy

open access: yesPediatric Investigation, Volume 10, Issue 1, Page 86-100, February 2026.
Anti‐seizure medications are the first‐line treatment for the vast majority of children with epilepsy, with the advantages of non‐invasive wide adaptability. Surgery is the main treatment for drug‐resistant epilepsy and lesion‐related epilepsy, which can cure some cases of epilepsy in children. A ketogenic diet is often an add‐on therapy.

Enantioselective Diels−Alder Reactions with N-Hydroxy-N-phenylacrylamide

open access: yes, 2016
The use of hydroxamic acids as templates for Lewis acid catalyzed enantioselective Diels−Alder reactions has been examined. A very simple chiral Lewis acid, prepared by mixing optically pure binaphthol with 3 equiv of trimethylaluminum, catalyzes the [4 +

Pipecolic acid as a diagnostic marker of pyridoxine-dependent epilepsy.

open access: yes, 2005
Pyridoxine-dependent epilepsy, although described some decades ago, may still be an underdiagnosed disorder. We have recently described isolated pipecolic acid elevations in the plasma and/or CSF of three patients with pyridoxine-dependent epilepsy with ...
