PPK was isolated and it was kinetically characterized in initial rate kinetic experiments. A rate equation was parameterized and used to simulate enzyme incubations

Fat quantification of 5 liver lobes (RML, LML, LLL, RL, CL) During the MRI sesssion at least one PRESS voxel was placed in each of those liver lobes to acquire PRESS data for later fat analysis. Acquisitions were without water suppression, so the fat peaks are relatively small.

The quantification was performed using lcmodel. The original MRI data are part of the MRI session assays (data files uploaded). Here you can find the additional analysis and the output of lcmodel: The "ps" in each exam ...

animals underwent a 60% PVL surgery and this MRI session was performed on post operation day 5 (POD5).

animals underwent a 60% PVL surgery and this MRI session was performed on post operation day 3 (POD3).

animals underwent a 60% PVL surgery and this MRI session was performed on post operation day 2 (POD2).

animals underwent a 60% PVL surgery and this MRI session was performed on post operation day 1 (POD1).

rats under control diet and no surgery to establish a baseline for fucntion, perfusion and fat content using MRI.

Abstract: Lung fibrosis, characterized by chronic and progressive scarring, has no cure. Hallmarks are the accumulation of myofibroblasts and extracellular matrix, as well as vascular remodeling. The crosstalk between myofibroblasts and vasculature is poorly understood, with ...

Abstract: N-Nitrosodimethylamine (NDMA) is an animal and probable human carcinogen. Here DNA adduct and high-resolution mutational spectra were correlated following administration of ...

Summary Glycogen is the principal carbon reserve in Synechocystis sp. PCC 6803. We reconstituted its biosynthetic pathway in vitro—GlgC (Glucose-1-phosphate adenylyltransferase), two glycogen synthase isoenzymes (GlgA1, GlgA2) and the branching enzyme GlgB—to define how supply, polymerisation and branching set flux and product structure. GlgA2 shows higher specific activity and cooperates with GlgB-generated branched primers, whereas GlgA1 has higher substrate affinity and responds more to primer ...

Abstract: Vaccine development for tuberculosis is a global priority. Our studies using Collaborative Cross (CC) mice show that genetic diversity influences the efficacy of BCG, the most widely used TB vaccine. BCG vaccination of CC042 mice reduces their lung bacillary burden and increases their survival following low-dose aerosol Mycobacterium tuberculosis infection ...

Abstract: Intravenous (IV) vaccination with Bacillus Calmette–Guerin (BCG) mediates sterilizing immunity against Mycobacterium tuberculosis (Mtb) in rhesus macaques but the cellular mechanisms ...

This study investigates how Fc-engineered antibodies affect Mycobacterium tuberculosis (Mtb) growth through antibody-dependent enhancement (ADE). We engineered 16 Fc variants with two distinct Fab regions (710 and 712), both targeting antigen85B (Ag85B), creating 32 total antibody variants. These variants were comprehensively profiled across five antibody effector functions: antibody-dependent neutrophil phagocytosis (ADNP), antibody-dependent monocyte phagocytosis (ADMP), antibody-dependent ...

Abstract: The incorporation of a functional perfusable microvascular network (MVN) is a common requirement for most organ on-chip-models. Long-term perfusion of MVNs is often required for the maturation of organ phenotypes and disease pathologies and to model the transport of cells and drugs entering ...
