Mesenchymal Stromal/Stem Cell Therapy Improves Salivary Flow Rate in Radiation-Induced Salivary Gland Hypofunction in Preclinical in vivo Models: A Systematic Review and Meta-Analysis.

Background: Mesenchymal stromal/stem cells (MSCs) have been suggested for salivary gland (SG) restoration following radio-induced salivary gland damage. This study aimed to determine the safety and effectiveness of MSC therapy on radio-induced SG damage and hypofunction in preclinical in vivo studies.

Methods: PubMed and EMBASE were systematically searched for preclinical in vivo interventional studies evaluating efficacy and safety of MSC treatment following radio-induced salivary gland damage published before 10th of January 2022.

Reporting of 3Rs Approaches in Preclinical Animal Experimental Studies-A Nationwide Study.

The 3Rs aim to refine animal welfare, reduce animal numbers, and replace animal experiments. Investigations disclose that researchers are positive towards 3Rs recommendations from peers. Communication of 3Rs approaches via primary preclinical animal experimental literature may become a fast-forward extension to learn relevant 3Rs approaches if such are reported.

Comparison of the neuromuscular effects of two infusion rates of rocuronium in anesthetized pigs.

Background: Neuromuscular blocking agents are frequently administered to pigs used for research. In humans, administration of the drugs is not without risk and may result in accidental awareness under general anaesthesia and postoperative residual neuromuscular blockade that can lead to serious respiratory complications. Despite the extensive administration, the pharmacodynamics of neuromuscular blocking agents are not thoroughly studied in pigs.

Reporting quality in preclinical animal experimental research in 2009 and 2018: A nationwide systematic investigation.

Lack of translation and irreproducibility challenge preclinical animal research. Insufficient reporting methodologies to safeguard study quality is part of the reason. This nationwide study investigates the reporting prevalence of these methodologies and scrutinizes the reported information's level of detail.

Mesenchymal stromal/stem cell therapy for radiation-induced salivary gland hypofunction in animal models: a protocol for a systematic review and meta-analysis.

Background: Salivary gland (SG) hypofunction (objectively reduced saliva flow rate) and xerostomia (subjective sensation of dry mouth) are common and burdensome side effects of radiotherapy to the head and neck region. Currently, only sparse symptomatic treatment is available to ease the discomfort of xerostomia. The objective of this study is to assess the effect of mesenchymal stem cell (MSC) therapy on SG function after radiation-induced injury.

Transition of Farm Pigs to Research Pigs using a Designated Checklist followed by Initiation of Clicker Training - a Refinement Initiative.

Implementation of 3R initiatives is important. To refine the life of laboratory pigs, we focused on the time period prior to inclusion of animals in experiments. We improved the checklist during the development.

Remote ischemic postconditioning for neuroprotection after newborn hypoxia-ischemia: systematic review of preclinical studies.

Background: Hypoxic-ischemic encephalopathy (HIE) is a major contributor to death and disability worldwide. Remote ischemic postconditioning (RIPC) may offer neuroprotection but has only been tested in preclinical models. Various preclinical models with different assessments of outcomes complicate interpretation.

High doses of ANP and BNP exacerbate lipolysis in humans and the lipolytic effect of BNP is associated with cardiac triglyceride content in pigs.

Drugs facilitating the cardioprotective effects of natriuretic peptides are introduced in heart failure treatment. ANP and BNP also stimulate lipolysis and increase circulating concentrations of free fatty acids (FFAs); an aspect, however, thought to be confined to primates. We examined the lipolytic effect of natriuretic peptide infusion in healthy young men and evaluated the effect in a porcine model of myocardial ischemia and reperfusion.

The evidence for the physiological effects of lactate on the cerebral microcirculation: a systematic review.

Lactate's role in the brain is understood as a contributor to brain energy metabolism, but it may also regulate the cerebral microcirculation. The purpose of this systematic review was to evaluate evidence of lactate as a physiological effector within the normal cerebral microcirculation in reports ranging from in vitro experiments to in vivo studies in animals and humans. Following pre-registration of a review protocol, we systematically searched the PubMed, EMBASE, and Cochrane databases for literature covering themes of 'lactate', 'the brain', and 'microcirculation'.

A Preclinical Study of Casein Glycomacropeptide as a Dietary Intervention for Acute Mania.

Background: Casein glycomacropeptide is a peptide that lacks phenylalanine, tyrosine, and tryptophan. This profile may enable it to deplete phenylalanine, tyrosine, and tryptophan, and subsequently the synthesis of dopamine and serotonin in the brain. Dopamine- and serotonin-depleting amino acid mixtures have shown promise as acute antimanic treatments.

Systematic evaluation of skeletal fractures caused by induction of electroconvulsive seizures in rat state a need for attention and refinement of the procedure.

Objective: Electroconvulsive therapy (ECT) is one of the most efficient treatments for major depression. Electroconvulsive seizures (ECS), the animal model of ECT, is widely used to study both mechanisms of action and adverse effects of ECT. As the treatment itself serves as an instant anaesthetic and anaesthetic agents may affect memory functions and behaviour, ECS is traditionally administered without muscle relaxation and anaesthesia.

Natriuretic peptides in cardiometabolic regulation and disease.

In the 30 years since the identification of the natriuretic peptides, their involvement in regulating fluid and blood pressure has become firmly established. Data indicating a role for these hormones in lifestyle-related metabolic and cardiovascular disorders have also accumulated over the past decade. Dysregulation of the natriuretic peptide system has been associated with obesity, glucose intolerance, type 2 diabetes mellitus, and essential hypertension.

Increased N-terminal CgA in circulation associated with cardiac reperfusion in pigs.

Aim: Acute myocardial infarction causes neurohumoral activation characterized by increased sympathetic activity. CgA is a protein released during sympathoadrenal stress from neuroendocrine tissue. Recently, increased CgA concentrations in circulation have been reported and suggested to be an independent predictor of mortality after acute myocardial infarction.

Natriuretic peptides as therapy in cardiac ischaemia/reperfusion.

Natriuretic peptides elicit vasodilation, increased sodium excretion and concomitant diuresis, and counteract the RAAS. In the heart itself, natriuretic peptides may also act anti-inflammatory and antifibrotic. This has led to the pursuit of natriuretic peptides and chemically modified peptides as adjunctive therapy in myocardial ischaemia.
