Evaluation of Microencapsulation of The UFV-AREG1 Bacteriophage in Alginate-Ca Microcapsules using Microfluidic Devices [PDF]

open access: yes, 2017
The indiscriminate use of antibiotics and the emergence of resistant microorganisms have become a major challenge for the food industry. The purpose of this work was to microencapsulate the bacteriophage UFV-AREG1 in a calcium alginate matrix using microfluidic devices and to study the viability and efficiency of retention. The microcapsules were added

Bioengineering a Patient‐Derived Vascularized Lung Tumor‐on‐Chip Model to Decipher Immunomodulation by the Endothelium

open access: yesAdvanced Healthcare Materials, EarlyView.
Most in vitro cancer models lack cellular diversity, functional complexity, and clinical relevance. This work highlights the generation of an innovative dynamic tetraculture with autologous patient‐derived cells within a vascularized tumor‐on‐chip, as well as the recapitulation of endothelial anergy features induced by the tumor microenvironment ...

Germany’s agri-biotechnology policy [PDF]

open access: yes, 2005
In Germany, the precautionary principle (PP) is a well-established legal principle in environmental law, especially for regulating agribiotechnology. This article uses the analytical concept of issue-framing to identify different views of the PP and how ...

Chemical contamination mediated regime shifts in planktonic systems [PDF]

open access: yesarXiv, 2020
Abrupt transitions leading to algal blooms are quite well known in aquatic ecosystems and have important implications for the environment. These ecosystem shifts have been largely attributed to nutrient dynamics and food web interactions. Contamination with heavy metals such as copper can modulate such ecological interactions which in turn may impact ...

Longer Acting Injectable: Continuous, Linear Release of a Progestin Contraceptive From an Oxidized Porous Silicon Host

open access: yesAdvanced Healthcare Materials, EarlyView.
Progestin drugs are loaded into a mesoporous silicon dioxide host by melt‐infiltration. Drugs that decompose at or close to their melting point can be loaded by the addition of cholesterol, which acts as a melting point suppressor. High mass loading of the drug is achieved, and dissolution of the composite is controlled by the nanoscale properties of ...

What You Don’t Know Can Hurt You: Micronutrient Content and Fungal Contamination of Foods in Developing Countries [PDF]

open access: yes
The negative effects of micronutrient deficiencies on human capital acquisition and economic productivity are well documented. A less well understood but potentially serious threat to human health in developing countries is the contamination of food ...

Low-cost spectrogram based counterfeit medicine detection [PDF]

open access: yesarXiv, 2019
Contaminated substances such as counterfeit medication and food contami-nated with pesticide residue is a pandemic of utmost urgency. Spectroscopy and chromatography methods are often used but are expensive and complex and as such a need exists for a device that can be easily operated in developing commu-nities. We present a hacked visible spectrometer

Engineered Chitosan‐Derived Nanocarrier for Efficient siRNA Delivery to Peripheral and Central Neurons

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces a novel chitosan‐based nanocarrier functionalized with a neurotropic protein for efficient siRNA delivery to neurons. The polyplexes demonstrate enhanced neuronal binding, retrograde transport, and PTEN silencing, promoting axonal outgrowth.

SHORT-TERM EFFECT OF DISPERSION OF RESIDUAL SLUDGE ON THE SOIL EUCALYPTUS CAMALDULENSIS DEHNH, TIARET (ALGERIA) [PDF]

open access: yes, 2018
Silvicultural upgrading of sewage sludge is an alternative to current solutions. It presents a lower risk of contamination of the human food chain than its use in agriculture.
