Pro- and Anti-fibrogenic Functions of Gram-Negative Bacterial Lipopolysaccharide in the Liver

open access: yesFrontiers in Medicine, 2020
Extensive research performed over several decades has identified cells participating in the initiation and progression of fibrosis, and the numerous underlying inter- and intra-cellular signaling pathways.

Topological field theory of time-reversal invariant insulators [PDF]

open access: yes, 2008
We show that the fundamental time-reversal invariant (TRI) insulator exists in $4+1$ dimensions, where the effective-field theory is described by the $(4+1)$-dimensional Chern-Simons theory and the topological properties of the electronic structure are ...

Sapitinib Reverses Anticancer Drug Resistance in Colon Cancer Cells Overexpressing the ABCB1 Transporter

open access: yesFrontiers in Oncology, 2020
The efficacy of anti-cancer drugs in patients can be attenuated by the development of multi-drug resistance (MDR) due to ATP-binding cassette (ABC) transporters overexpression.

Restoring Blood Pressure in Hypertensive Mice Fails to Fully Reverse Vascular Stiffness

open access: yesFrontiers in Physiology, 2020
BackgroundHypertension is a well-established driver of vascular remodeling and stiffening. The goal of this study was to evaluate whether restoring normal blood pressure (BP) fully restores vascular stiffness toward that of normotensive controls ...

Inter-tissue convergence of gene expression during ageing suggests age-related loss of tissue and cellular identity

open access: yeseLife, 2022
Developmental trajectories of gene expression may reverse in their direction during ageing, a phenomenon previously linked to cellular identity loss. Our analysis of cerebral cortex, lung, liver, and muscle transcriptomes of 16 mice, covering development

Paired states of fermions in two dimensions with breaking of parity and time-reversal symmetries and the fractional quantum Hall effect [PDF]

open access: yes, 1999
We analyze pairing of fermions in two dimensions for fully gapped cases with broken parity (P) and time reversal (T), especially cases in which the gap function is an orbital angular momentum (l) eigenstate, in particular $l=\ensuremath{-}1$ (p wave ...

Lipolysis sensation by white fat afferent nerves triggers brown fat thermogenesis

open access: yesMolecular Metabolism, 2016
Objective: Metabolic challenges, such as a cold environment, stimulate sympathetic neural efferent activity to white adipose tissue (WAT) to drive lipolysis, thereby increasing the availability of free fatty acids as one source of fuel for brown adipose ...

Instructed knowledge shapes feedback-driven aversive learning in striatum and orbitofrontal cortex, but not the amygdala

open access: yeseLife, 2016
Socially-conveyed rules and instructions strongly shape expectations and emotions. Yet most neuroscientific studies of learning consider reinforcement history alone, irrespective of knowledge acquired through other means.

Chemical immobilisation of the wild Patagonian otter (Lontra provocax) and the North American mink (Neovison vison)

open access: yesAustral Journal of Veterinary Sciences, 2021
The Patagonian otter (Lontra provocax) is an endangered species endemic to southern Chile and Argentina. Most of its distribution range has recently been occupied by the American mink (Neovison vison).
