Preclinical 1H MRS Study of a Porcine Model Shows Evidence and Mechanisms for Acute Neuronal Injury in Neonatal Cardiopulmonary Bypass (CPB) Surgery

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Congenital heart disease affects 1% of US births, with some infants requiring cardiothoracic surgery under cardiopulmonary bypass (CPB). Optimal surgical parameters to minimize neuronal injury are unknown. We used serial 1H MRS in a neonatal CPB porcine model to assess acute neuronal damage and associated injury mechanisms.

A fast ethanol assay to detect seed deterioration [PDF]

, 2012
The most common way to test seed quality is to use a simple and reliable but time- and space-consuming germination test. In this paper we present a fast and simple method to analyse cabbage seed deterioration by measuring ethanol production from ...

Repeatability of Metabolic Imaging With Hyperpolarized Pyruvate: Back‐to‐Back Neuroimaging and Blood Analysis

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose 13C MRI with hyperpolarized [1‐13C]pyruvate enables noninvasive imaging of metabolic pathways. Considering the high dose of pyruvate used in hyperpolarized 13C‐pyruvate studies, circulating 13C‐pyruvate and the resulting 13C‐lactate in plasma may influence subsequent pyruvate metabolism, yet the guidance on consecutive injections does ...

Rapid Metabolic Recovery Following Vigorous Exercise in Burrow-Dwelling Larval Sea Lampreys (\u3cem\u3ePetromyzon marinus\u3c/em\u3e) [PDF]

, 2001
Although the majority of the sea lamprey’s (Petromyzon marinus) life cycle is spent as a burrow-dwelling larva, or ammocoete, surprisingly little is known about intermediary metabolism in this stage of the lamprey’s life history.

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Pasteur effect in leukocyte energy metabolism of patients with mild, moderate, and severe COVID-19

Türk Biyokimya Dergisi
The Pasteur effect in cellular energy metabolism is defined as the switch to anaerobic glycolysis due to alterations in ambient oxygen concentration or inhibition of the electron transport chain (ETC) and oxidative phosphorylation.

Microglial Activation Under Hypoxic Conditions in Early Alzheimer's Disease: Can Natural SIRT1 Activators Be Therapeutic Allies in the Inflammation–Energy Axis?

Phytotherapy Research, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative condition characterized by a preclinical stage that typically lasts for decades. Early on during this time, microglia react to pathological changes and become protective and even transiently delay neurodegeneration.

Evaluation of a rapid method for measuring lactate in the venous blood of ruminants

Veterinary Record, EarlyView.
Abstract Background In cattle and small ruminants, blood lactate can predict recovery and survival in various diseases. Increased lactate concentration is associated with an unfavourable‐to‐poor prognosis. Different mobile rapid lactate measurement devices have been explored in different animal species.

NAD Metabolism in Cancer Therapeutics

Frontiers in Oncology, 2018
Cancer cells have a unique energy metabolism for sustaining rapid proliferation. The preference for anaerobic glycolysis under normal oxygen conditions is a unique trait of cancer metabolism and is designated as the Warburg effect.

Modeling the lung‒brain axis in critical illness: Multifactorial crosstalk through organoids and organ‐on‐a‐chip system

VIEW, EarlyView.
Patients in intensive care units often experience lung injuries, complicated by brain problems. Advanced laboratory tools, organoids, and organs‐on‐chips facilitated the study of multiorgan interactions, help us understand the communication between the lungs and brain.
