Effects of a postbiotic, with and without a saponin-based product, on turkey performance.

Modern poultry production relies on an ability to prevent and mitigate challenges to bird health, while maintaining a productive bird. A number of different classes of biologics-based feed additives exist, and many have been tested individually for their impacts on poultry health and performance. Fewer studies have examined the combinations of different classes of products.

Data Analytics Approach for Rational Design of Nanomedicines with Programmable Drug Release.

Drug delivery vehicles can improve the functional efficacy of existing antimicrobial therapies by improving biodistribution and targeting. A critical property of such nanomedicine formulations is their ability to control the release kinetics of their payloads. The combination of (and interactions among) polymer, drug, and nanoparticle properties gives rise to nonlinear behavioral relationships and large data space.

Nanotherapeutic provides dose sparing and improved antimicrobial activity against Brucella melitensis infections.

New therapies are needed to treat chronic bacterial diseases and intracellular pathogens, in particular, are very difficult to manage. The use of nanotherapeutics represents an approach to exploit size and charge of biological membranes to overcome barriers for treatment of intracellular pathogens including Brucella melitensis. In this work, polyanhydride nanoparticles comprised of copolymers of sebacic acid, 1,6-bis(p-carboxyphenoxy)hexane, and 1,8-bis(p-carboxyphenoxy)-3,6-dioxaoctane were synthesized to encapsulate antimicrobial compounds doxycycline and rifampicin.

Polyanhydride Nanoparticle Delivery Platform Dramatically Enhances Killing of Filarial Worms.

Filarial diseases represent a significant social and economic burden to over 120 million people worldwide and are caused by endoparasites that require the presence of symbiotic bacteria of the genus Wolbachia for fertility and viability of the host parasite. Targeting Wolbachia for elimination is a therapeutic approach that shows promise in the treatment of onchocerciasis and lymphatic filariasis. Here we demonstrate the use of a biodegradable polyanhydride nanoparticle-based platform for the co-delivery of the antibiotic doxycycline with the antiparasitic drug, ivermectin, to reduce microfilarial burden and rapidly kill adult worms.

Nano-enabled delivery of diverse payloads across complex biological barriers.

Complex biological barriers are major obstacles for preventing and treating disease. Nanocarriers are designed to overcome such obstacles by enhancing drug delivery through physiochemical barriers and improving therapeutic indices. This review critically examines both biological barriers and nanocarrier payloads for a variety of drug delivery applications.
