Anesthesia and analgesia for common research models of adult mice. Lab Anim Res 2022; 38:40. [PMID: 36514128 PMCID: PMC9746144 DOI: 10.1186/s42826-022-00150-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 11/23/2022] [Accepted: 12/06/2022] [Indexed: 12/15/2022] Open
Abstract
Anesthesia and analgesia are major components of many interventional studies on laboratory animals. However, various studies have shown improper reporting or use of anesthetics/analgesics in research proposals and published articles. In many cases, it seems "anesthesia" and "analgesia" are used interchangeably, while they are referring to two different concepts. Not only this is an unethical practice, but also it may be one of the reasons for the proven suboptimal quality of many animal researches. This is a widespread problem among investigations on various species of animals. However, it could be imagined that it may be more prevalent for the most common species of laboratory animals, such as the laboratory mice. In this review, proper anesthetic/analgesic methods for routine procedures on laboratory mice are discussed. We considered the available literature and critically reviewed their anesthetic/analgesic methods. Detailed dosing and pharmacological information for the relevant drugs are provided and some of the drugs' side effects are discussed. This paper provides the necessary data for an informed choice of anesthetic/analgesic methods in some routine procedures on laboratory mice.

Effects of a collagen hyaluronic acid silk-fibroin patch with the electroconductive element polyaniline on left ventricular remodeling in an infarct heart model. J Biomed Mater Res B Appl Biomater 2022; 110:1651-1666. [PMID: 35099115 DOI: 10.1002/jbm.b.35026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Revised: 01/13/2022] [Accepted: 01/18/2022] [Indexed: 11/10/2022]
Abstract
Biodegradable cardiac patches have been able to induce improvement in left ventricular (LV) remodeling. A novel scaffold patch made with collagen and silk-fibroin (COL-SF) was further associated to polyaniline (PANi) to increase conductivity. Thus, this study investigated the safety of the association of PANi to a patch, and the improvement in LV remodeling in a myocardial infarct (MI) rat model. Wistar rats underwent MI induction. MI was confirmed with echocardiographic and after 2 weeks, animals (n = 10/group) were randomized into: (a) COL-SF hyaluronic acid patch, (b) PANi hyaluronic acid patch, (c) MI Control (just repeat thoracotomy). Healthy animals were also followed. Echocardiography was performed at pre-treatment, and at 2-, 4-, and 8-weeks post-treatment. Hearts underwent hemodynamic evaluation on Langendorff apparatus and histology for LV thickness and percent of infarct size. Liver, kidneys, and blood samples were evaluated for biochemical, hematological, oxidative stress, and histology. There was a tendency of lower %infarct size in patched animals. LV thickness was higher in the patched animals than controls. Functional echocardiographic indices %Fractional shortening and %LV ejection fraction decreased in the MI control group, but not in the patched animals. PANi presented higher %LVEF versus MI control. PANi presented higher liver transaminases; no morphological changes were observed in histology. Elevation of antioxidant markers was observed. COL-SF and PANi patches were able to induce better remodeling features compared to MI controls on %infarct size and LV thickness and have not presented echocardiographic worsening. Polyaniline may present a slight improvement on LV remodeling, despite associated to signs of hepatotoxicity and pro-oxidant effect.

In vivo demonstration of a novel non-invasive model for inducing localized hypothermia to ameliorate hepatotoxicity. Sci Rep 2021; 11:18620.

Abstract
Moderate hypothermia (32 °C) has been previously shown to ameliorate drug-induced liver injuries in vitro. However, there are concerns regarding its clinical relevance as it remains a challenge to perform selective liver cooling in a non-invasive manner. To reconcile this dilemma, we propose the use of pulsed cooling for regional hypothermic conditioning in liver. This involves intermittent cooling applied in pulses of 15 min each, with a one-hour recovery interval between pulses. Cooling is achieved by applying ice packs to the cutaneous region overlying the liver. Through an in vivo C57BL/6NTac mouse study, we demonstrated the feasibility of attaining localized hypothermia close to the liver while maintaining core body temperature. This has successfully ameliorated acetaminophen-induced liver injury based on the liver function tests, liver histology and total weight change. Collectively, we provide a proof of concept for pulsed external localized cooling as being clinically actionable to perform induced selective hypothermia.

Li X, Yao Q, Li R, Jin Y. Isoflurane induces liver injury by modulating the expression of miR-125a-5p. Clin Res Hepatol Gastroenterol 2021; 45:101732. [PMID: 34139319 DOI: 10.1016/j.clinre.2021.101732] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 05/12/2021] [Accepted: 05/26/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND Isoflurane can cause hepatotoxicity, and microRNAs (miRNAs) are involved in the regulation of liver injury. Therefore, this study aimed to explore the effect of miR-125a-5p on isoflurane-induced liver injury. BASIC PROCEDURES Sprague-Dawley (SD) male rats and BRL-3A cells were exposed to isoflurane to construct animal and cell models. Serum alanine transaminase (ALT) and aspartate transaminase (AST) levels of rats were detected. RT-qPCR was performed for the measurement of miR-125a-5p levels. Cell proliferation and apoptosis were also detected. MAIN FINDINGS After isoflurane treatment, serum ALT and AST levels of rats increased in a time-dependent manner, and the differences reached significant levels from 3 days after isoflurane treatment. MiR-125a-5p levels increased significantly in the liver tissues of isoflurane-treated rats. MiR-125a-5p downregulation significantly attenuated isoflurane-induced increasing trend of serum ALT and AST levels in rats. In BRL-3A cells, isoflurane treatment significantly inhibited cell proliferation and promoted cell apoptosis, which was reversed by miR-125a-5p downregulation. PRINCIPAL CONCLUSIONS Isoflurane exposure significantly elevates the level of miR-125a-5p in the liver tissues of rats. Downregulation of miR-125a-5p may protect against isoflurane-induced liver injury through regulating liver cell proliferation and apoptosis. Dysregulation of miR-125a-5p might be a possible mechanism of isoflurane-induced liver injury.

Abstract
Surgery for patients with complicated liver cancer often results in a long exposure to anesthesia with an increase in side effects. Continued long-term exposure to isoflurane may promote liver cancer progression. Small ubiquitin-like modifier (SUMO) 2 and 3, also known as SUMO2/3, conjugates to substrate proteins when cells undergo acute stress. However, whether or not SUMO2/3 is involved in isoflurane-mediated liver cancer progression is unknown. In the present study, hepatocellular carcinoma (HCC) cells were exposed to 2% isoflurane for 12 h, followed by 36 h of drug withdrawal, and the formation of SUMO2/3 conjugates and cancer behavioral characteristics were studied. The results demonstrated that the formation of SUMO2/3 conjugates was significantly increased following HCC cells being exposed to isoflurane for 0.5 h, and continued to increase for 48 h, even after the drug had been withdrawn. Furthermore, isoflurane-exposed HCC cells exhibited increased proliferation and invasion activity during the subsequent observation period. SUMO specific protease 3 (SENP3), which inhibits the binding of SUMO2/3 to its target proteins, was overexpressed and it was discovered that isoflurane-induced SUMOylation was significantly inhibited, and accordingly, the proliferation and invasion abilities of HCC cells were decreased to a certain extent. These findings indicated that SUMO2/3 is involved in the progression of HCC cells, at least in the Hep3B cell line, induced by the anesthetic isoflurane, and that inhibition of SUMO2/3 may antagonize the response. These results provided a novel target for decreasing the adverse reactions occurring in patients with HCC during anesthesia, particularly those who are exposed to isoflurane for long periods of time.

Abstract
Background: Hepatic dysfunction plays a major role in adverse outcomes in sepsis. Volatile anesthetic agents may protect against organ dysfunction in the setting of critical illness and infection. The goal of this study was to study the impact of Sepsis-inflammation on hepatic subcellular energetics in animals anesthetized with both Propofol (intravenous anesthetic agent and GABA agonist) and Isoflurane (volatile anesthetic i.e., VAA). Methods: Sprague-Dawley rats were anesthetized with Propofol or isoflurane. Rats in each group were randomized to celiotomy and closure (control) or cecal ligation and puncture “CLP” (Sepsis-inflammation) for 8 h. Results: Inflammation led to upregulation in hepatic hypoxia-inducible factor-1 in both groups. Rats anesthetized with isoflurane also exhibited increases in bcl-2, inducible nitric oxide synthase, and heme oxygenase-1(HO-1) during inflammation, whereas rats anesthetized with Propofol did not. In rats anesthetized with isoflurane, decreased mRNA, protein (Complex II, IV, V), and activity levels (Complex II/III,IV,V) were identified for all components of the electron transport chain, leading to a decrease in mitochondrial ATP. In contrast, in rats anesthetized with Propofol, these changes were not identified after exposure to inflammation. RNA-Seq and real-time quantitative PCR (qPCR) expression analysis identified a substantial difference between groups (isoflurane vs. Propofol) in mitogen-activated protein kinase (MAPK) related gene expression following exposure to Sepsis-inflammation. Conclusions: Compared to rats anesthetized with Propofol, those anesthetized with isoflurane exhibit more oxidative stress, decreased oxidative phosphorylation protein expression, and electron transport chain activity and increased expression of organ-protective proteins.

Abstract
Mitochondria are organelles that are essential for cellular homeostasis including energy harvesting through oxidative phosphorylation. Mitochondrial dysfunction plays a vital role in liver diseases as it produces a large amount of reactive oxygen species (ROS), in turn leading to further oxidative damage to the structure and function of mitochondria and other cellular components. More severe oxidative damage occurred in mitochondrial DNA (mtDNA) than in nuclear DNA. mtDNA dysfunction results in further oxidative damage as it participates in encoding respiratory chain polypeptides. In addition, mtDNA can leave the mitochondria and enter the cytoplasm and extracellular environment. mtDNA is derived from ancient bacteria, contains many unmethylated CpG dinucleotide repeats similar to bacterial DNA, and thus can induce inflammation to exacerbate damage to liver cells and distal organs by activating toll-like receptor 9, inflammatory bodies, and stimulator of interferon genes (STING). In this review, we focus on the mechanism by which mtDNA alterations cause liver injuries, including nonalcoholic fatty liver, alcoholic liver disease, drug-induced liver injury, viral hepatitis, and liver cancer.

Abstract
Studies on fluorinated inhalation anesthetics, including synthesis, physical chemistry and
pharmacology, have been summarized in this review. Retrospecting the history of inhalation anesthetics
revealed their increasing reliance on fluorine and ether structures. Halothane causes a rare but
severe immune-based hepatotoxicity, which was replaced by enflurane in the 1970s. Isoflurane replaced
enflurane in the 1980s, showing modest advantages (e.g. lower solubility, better metabolic
stability, and without convulsive predisposition). Desflurane and sevoflurane came into use in the
1990s, which are better anesthetics than isoflurane (less hepatotoxicity, lower solubility, and/or
markedly decreased pungency). However, they are still less than perfect. To gain more ideal inhalation
anesthetics, a large number of fluorinated halocarbons, polyfluorocycloalkanes, polyfluorocycloalkenes,
fluoroarenes, and polyfluorooxetanes, were prepared and their potency and toxicity were
evaluated. Although the pharmacology studies suggested that some of these agents produced anesthesia,
no further studies were continued on these compounds because they showed obvious lacking
as anesthetics. Moreover, the anesthetic activity cannot be simply predicted from the molecular
structures but has to be inferred from the experiments. Several regularities were found by experimental
studies: 1) the potency and toxicity of the saturated linear chain halogenated ether are enhanced
when its molecular weight is increased; 2) the margin of safety decreases and the recovery
time is prolonged when the boiling point of the candidate increases; and 3) compounds with an
asymmetric carbon terminal exhibit good anesthesia. Nevertheless, the development of new inhalation
anesthetics, better than desflurane and sevoflurane, is still challenging not only because of the
poor structure/activity relationship known so far but also due to synthetic issues.

Abstract
Police violence is reportedly common among those diagnosed with mental disorders characterized by the presence of psychotic symptoms or pronounced emotional lability. Despite the perception that people with mental illness are disproportionately mistreated by the police, there is relatively little empirical research on this topic. A cross-sectional general population survey was administered online in 2017 to 1,000 adults in two eastern U.S. cities to examine the relationship between police violence exposure, mental disorders, and crime involvement. Results from hierarchical logistic regression and mediation analyses revealed that a range of mental health conditions are broadly associated with elevated risk for police violence exposure. Individuals with severe mental illness are more likely than the general population to be physically victimized by police, regardless of their involvement in criminal activities. Most of the excess risk of police violence exposure related to common psychiatric diagnoses was explained by confounding factors including crime involvement. However, crime involvement may necessitate more police contact, but does not necessarily justify victimization or excessive force (particularly sexual and psychological violence). Findings support the need for adequate training for police officers on how to safely interact with people with mental health conditions, particularly severe mental illness.

Abstract
BACKGROUND Anesthesia is a major component of surgery and recently considered an important regulator of cell phenotypes. Here we aimed to investigate propofol, an anesthesia drug, in suppressing pancreatic cancer (PDAC), focusing on A disintegrin and metalloprotease 8, (ADAM8) as a molecular mediator. METHODS Quantitative real-time PCR and western blot were used to assess the change of ADAM8 expression in Panc1 PDAC cells treated with 5 or 10 μg/mL propofol, using cells treated with BB-94 inhibitor as controls. ADAM8 activity was measured through quantifying fluorescence release induced by PEPDAB013 decomposition. MTT assay, scratch wound assay and Matrigel invasion assay were used to investigate the proliferation, migration and invasion of the cells. Western blot and immunohistochemical analysis were used to quantify integrin β1, ERK1/2, MMP2 and MMP9 expression. RESULTS Propofol and BB-94 reduced ADAM8 expression, cell proliferation and migration of Panc1 cells. Tumor growth was inhibited by propofol and BB-94, concomitant with downregulation of integrin β1, ERK1/2, MMP2 and MMP9. ADAM8 is downregulated by propofol, leading to inhibition of pancreatic cancer proliferation and migration. CONCLUSION Pancreatic tumor growth is also inhibited by propofol and BB-94, which is attributed to suppression of ERK/MMPs signaling.

Abstract
This study aimed to detect the effect of sevoflurane anesthesia on liver injury through modulating IGF-1. The expression of IGF-1 and IGF-1R in liver tissues of sevoflurane-exposed rats was examined by qRT-PCR and Western blot. The expression levels of miR-214 in liver cells treated with different concentration of sevoflurane at different time points were detected by qRT-PCR. Enzyme-linked immunosorbent (ELISA) assay was used to analyze serum IGF-1 concentration in cell culture media. After pre-treatment with 100 nM miR-214 inhibitor followed by exposure to sevoflurane, the expression level of miR-214 and IGF-1 protein in liver cells was examined. Hematoxylin-Eosin (HE) staining and TUNEL assay was performed to analyze liver tissue necrosis and apoptosis. The expression levels of apoptosis-related proteins (caspase 3 and Bcl-xL) were examined using Western blot. The mRNA and protein expression level of IGF-1 and IGF-1R in rats was significantly down-regulated after 90 min exposure to sevoflurane. QRT-PCR results suggested that exposure to sevoflurane upregulated the expression level of miR-214 and decreased the concentration of IGF-1 in a dose and time dependent manner. Sevoflurane inhibited the expression of IGF-1 through up-regulating miR-214. IGF-1 inhibited the positive effect of sevoflurane on cell necrosis and apoptosis. Sevoflurane could induce liver injury by modulating IGF-1 expression via miR-214.
