From Membrane Composition to Antimicrobial Strategies: Experimental and Computational Approaches to AMP Design and Selectivity

open access: yesSmall, EarlyView.
Antimicrobial peptides (AMPs) are promising candidates for next‐generation antibiotics, acting through mechanisms such as membrane disruption and intracellular targeting. This review examines how variations in bacterial membrane composition critically influence AMP activity.

Hydrogenase Mediated Biosynthesis of Catalytically Active Cu Nanoparticles

open access: yesSmall, EarlyView.
Shewanella oneidensis MR‐1 biosynthesized cell‐supported, catalytically active Cu‐nanoparticles (CuNPs). Hydrogen is the only electron donor that supports Cu(II) bioreduction to CuNPs, with hydrogenase deletion mutants indicating involvement of the periplasmic [NiFe] hydrogenase, HyaB.

Evaluation of two candidate molecules—TCTP and cecropin—on the establishment of Trypanosoma brucei gambiense into the gut of Glossina palpalis gambiensis

open access: yesInsect Science, EarlyView.
This study investigates the potential of enhancing the resistance of Glossina palpalis gambiensis to Trypanosoma brucei gambiense to mitigate the transmission of Human African Trypanosomiasis. We successfully cloned genes encoding proteins of interest in Sodalis strains, resulting in recombinant Sodalis (recSodalis) that were micro‐injected into the L3

Extraction and structural study of hemicellulose B from tall fescue (Festuca arundinacea) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Chemistry at Massey University [PDF]

open access: yes, 1971
1.1 Hemicellulose The structural carbohydrates are mixtures of polysaccharides which together with lignin, constitute the cell wall. Usually they are divided into three fractions: pectic substances, hemicellulose and cellulose.1 Pectins, widely ...

Anti‐melanogenic effects of Medicago sativa seed extracts on melanocytes

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Our study demonstrated that two types of alfalfa seed extract: alfalfa ethanol precipitate (AEP) and alfalfa ethanol supernatant (AES) inhibited melanogenesis through the downregulation of tyrosinase expression, following the inactivation of CREB, b‐catenin and ERK signalling pathway in α‐melanocyte‐stimulating hormone (α‐MSH)‐stimulated B16F10 mouse ...

A bacterial gene-drive system efficiently edits and inactivates a high copy number antibiotic resistance locus. [PDF]

open access: yes, 2019
Gene-drive systems in diploid organisms bias the inheritance of one allele over another. CRISPR-based gene-drive expresses a guide RNA (gRNA) into the genome at the site where the gRNA directs Cas9-mediated cleavage.
