Review of the effects of manufactured nanoparticles on mammalian target organs

open access: yesJournal of Applied Toxicology, 2018
Nanotechnology had matured significantly during the last two decades as it has transitioned from bench top science to applied technology. Even though the issue of safety of nanotechnology has been raised nearly one decade ago, the rapid progress in ...

Involvement of UDP-Glucuronosyltransferases and Sulfotransferases in the Excretion and Tissue Distribution of Resveratrol in Mice. [PDF]

open access: yes, 2017
Resveratrol is a naturally occurring polyphenolic compound with various pharmacological activities. It is unknown whether the expression of metabolizing enzymes correlates with resveratrol levels in organs and tissues.

Personalised organs-on-chips: functional testing for precision medicine

open access: yesLab on a Chip, 2018
Organs-on-chips can be ‘personalised’ so they can be used as functional tests to inform clinical decision-making for specific patients.

Plasticity of differentiated cells in wound repair and tumorigenesis, Part II: Skin and intestine [PDF]

open access: yes, 2018
Recent studies have identified and begun to characterize the roles of regenerative cellular plasticity in many organs. In Part I of our two-part Review, we discussed how cells reprogram following injury to the stomach and pancreas.

C:N:P stoichiometry in China's forests: From organs to ecosystems

open access: yes, 2018
Summary Ecological stoichiometry connects different levels of biology, from the gene to the globe, by scaling up elemental ratios (e.g., carbon [C], nitrogen [N], and phosphorus [P]). Thus, ecological stoichiometry could be a powerful tool for revealing

Organ‐on‐a‐Chip for Cancer and Immune Organs Modeling

open access: yesAdvanced Healthcare Materials, 2019
Bridging the gap between findings in preclinical 2D cell culture models and in vivo tissue cultures has been challenging; the simple microenvironment of 2D monolayer culture systems may not capture the cellular response to drugs accurately.

Ultrasonic biomedical measuring and recording apparatus [PDF]

open access: yes, 1974
A train of ultrasonic pulses is beamed into the body of an animal. Organs intercepted by the beam reflect echo pulses following each transmitted pulse. An electronic gate with a variable width and a variable time delay relative to the transmitted pulse ...

Transplantation of the heart after circulatory death of the donor: time for a change in law? [PDF]

open access: yes, 2015
Procurement of organs has always been conducted according to the dead donor rule, that is, after death of the donor — but this practice is being challenged. Introduction Australia has an increasing shortfall in transplantable hearts.

Iron overload in thalassemia: different organs at different rates.

open access: yesHematology. American Society of Hematology. Education Program, 2017
Thalassemic disorders lie on a phenotypic spectrum of clinical severity that depends on the severity of the globin gene mutation and coinheritance of other genetic determinants.

The extraction of the new components from electrogastrogram (EGG), using both adaptive filtering and electrocardiographic (ECG) derived respiration signal [PDF]

open access: yes, 2015
Electrogastrographic examination (EGG) is a noninvasive method for an investigation of a stomach slow wave propagation. The typical range of frequency for EGG signal is from 0.015 to 0.15 Hz or (0.015–0.3 Hz) and the signal usually is captured with ...
