Gut microbiota Turicibacter strains differentially modify bile acids and host lipids

open access: yesNature Communications, 2023
Bacteria from the Turicibacter genus are prominent members of the mammalian gut microbiota and correlate with alterations in dietary fat and body weight, but the specific connections between these symbionts and host physiology are poorly understood.

A robust subspace based approach to feedforward control of broadband disturbances on a six-degrees-of-freedom vibration isolation set-up [PDF]

open access: yes, 2005
The contribution of this paper is twofold. First, the paper introduces a novel hybrid vibration isolation approach which uses a combination of passive and active vibration control techniques to provide additional design freedom.

Genetic and phenotypic divergence in an island bird: isolation by distance, by colonization or by adaptation? [PDF]

open access: yes, 2014
Discerning the relative roles of adaptive and nonadaptive processes in generating differences among populations and species, as well as how these processes interact, is a fundamental aim in biology.

Not reimbursing islet transplantation creates discrimination against patients with type 1 diabetes [PDF]

open access: yesCellR4, 2019
In this commentary reviewing the activity of the University of Geneva islet transplantation program, the author argues that health care coverage of the procedure will stop discrimination against a subset of patients with type 1 diabetes in need of beta ...

Sensor-fault tolerance using robust MPC with set-based state estimation and active fault isolation [PDF]

open access: yes, 2014
In this paper, a sensor fault-tolerant control (FTC) scheme using robust model predictive control (MPC) and set theoretic fault detection and isolation (FDI) is proposed.

Chemistry, Biological Activities and In Silico Bioprospection of Sterols and Triterpenes from Mexican Columnar Cactaceae

open access: yesMolecules, 2020
The Cactaceae family is an important source of triterpenes and sterols. The wide uses of those plants include food, gathering, medicinal, and live fences. Several studies have led to the isolation and characterization of many bioactive compounds.

Insulin-producing organoids engineered from islet and amniotic epithelial cells to treat diabetes

open access: yesNature Communications, 2019
Islet transplantation is a feasible approach to treat type I diabetes, however inflammation and poor vascularisation impair long-term engraftment. Here the authors show that incorporating human amniotic epithelial cells into islet organoids improves ...
