Esters in Australian geranium oil (Pelargonium hybrid)

open access: yes, 1999
This paper is the first detailed report of straight chain and branched esters in Australian geranium oil. Hydrodistillation of 41 samples of Australian-grown rose geranium (Pelargoniun hybrid) produced oils containing four detectable parent alcohols; 2 ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Nitrile oxides in medicinal chemistry .6. Enzymatic resolution of a set of bicyclic Delta(2)-isoxazolines.

open access: yes, 1996
Chymotrypsin selectively catalyzed the hydrolysis of a series of 3-ethoxycarbonyl-Delta(2)-isoxazolines 1-4, whereas lipase from Pseudomonas cepacia (lipase PS) was remarkably selective in hydrolysing the corresponding 3-hydroxymethyl-Delta(2)

Longitudinal Modulation of the Gut Microbiome and Growth Performance by Phytochemicals as Antibiotic Alternatives in Swine Production

open access: yesAnimal Research and One Health, EarlyView.
We conducted a longitudinal trial across nursery, growing, and finishing phases, showing that phytochemical supplementation as a potential antibiotic alternative reduced potential pathogens and promoted beneficial Lactobacillus amylovorus in the nursery phase, and enriched amino acid and carbohydrate metabolism pathways (prediction) during finishing ...

Carboxylesterases (EC 3.1.1). The source of variations in substrate specificity and properties of pig liver carboxylesterase

open access: yes, 1975
During the final stage of purification of pig liver carboxylesterase on CM-Sephadex, several enzyme activities are present in addition to the pig liver carboxylesterase reported from this laboratory (Horgan et al., 1969a).

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

open access: yesAnimal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Recent Advances in Virus–Host Interactions, Antiviral Bioactive Compounds, and Breeding for Disease Resistance of Porcine Epidemic Diarrhea Virus

open access: yesAnimal Research and One Health, EarlyView.
Basic research on the PEDV infection cycle and virus–host interactions advances the development of anti‐PEDV drugs and disease‐resistant breeding and helps strengthen disease prevention and control while reducing economic losses in the swine industry.

The Kinetics of Oxidation of Aldehydes to Acidsand Acid Anhydrides. II

open access: yes, 1956
Continuing our studies on the catalytic decomposition of peracids into acids and on the interaction of peracids with aldehydes into acids and acid anhydrides, we examined the influence of other mixed catalysts, i. e.

A new route to protected acyloins and their enzymatic resolution with lipases

open access: yes, 2004
A series of 16 different 3-acyloxy methyl ketones, the acyloin acetates and butyrates (±)-5, was synthesised by a straight-forward new method through alkylation of tert-butyl 2-acyloxyacetoacetates 3, followed by chemoselective dealkoxy-carbonylation of ...
