1Golgi protein-73:A biomarker for assessing cirrhosis and prognosis of liver disease patients显示文摘BACKGROUND Reliable biomarkers of cirrhosis,hepatocellular carcinoma(HCC),or progression of chronic liver diseases are missing.In this context,Golgi protein-73(GP73)also called Golgi phosphoprotein-2,was originally defined as a resident Golgi type II transmembrane protein expressed in epithelial cells.As a result,GP73 expression was found primarily in biliary epithelial cells,with only slight detection in hepatocytes.However,in patients with acute or chronic liver diseases and especially in HCC,the expression of GP73 is significantly up-regulated in hepatocytes.So far,few studies have assessed GP73 as a diagnostic or prognostic marker of liver fibrosis and disease progression.AIM To assess serum GP73 efficacy as a diagnostic marker of cirrhosis and/or HCC or as predictor of liver disease progression.METHODS GP73 serum levels were retrospectively determined by a novel GP73 ELISA(QUANTA Lite®GP73,Inova Diagnostics,Inc.,Research Use Only)in a large cohort of 632 consecutive patients with chronic viral and non-viral liver diseases collected from two tertiary Academic centers in Larissa,Greece(n=366)and Debrecen,Hungary(n=266).Aspartate aminotransferase(AST)/Platelets(PLT)ratio index(APRI)was also calculated at the relevant time points in all patients.Two hundred and three patients had chronic hepatitis B,183 chronic hepatitis C,198 alcoholic liver disease,28 autoimmune cholestatic liver diseases,15 autoimmune hepatitis,and 5 with other liver-related disorders.The duration of follow-up was 50(57)mo[median(interquartile range)].The development of cirrhosis,liver decompensation and/or HCC during follow-up were assessed according to internationally accepted guidelines.In particular,the surveillance for the development of HCC was performed regularly with ultrasound imaging and alpha-fetoprotein(AFP)determination every 6 mo in cirrhotic and every 12 mo in non-cirrhotic patients.RESULTS Increased serum levels of GP73(>20 units)were detected at initial evaluation in 277 out of 632 patients(43.8%).GP73-seropositivity correlated at baseline with the presence of cirrhosis(96.4%vs 51.5%,P<0.001),decompensation of cirrhosis(60.3%vs 35.5%,P<0.001),presence of HCC(18.4%vs 7.9%,P<0.001)and advanced HCC stage(52.9%vs 14.8%,P=0.002).GP73 had higher diagnostic accuracy for the presence of cirrhosis compared to APRI score[Area under the curve(AUC)(95%CI):0.909(0.885-0.934)vs 0.849(0.813-0.886),P=0.003].Combination of GP73 with APRI improved further the accuracy(AUC:0.925)compared to GP73(AUC:0.909,P=0.005)or APRI alone(AUC:0.849,P<0.001).GP73 levels were significantly higher in HCC patients compared to non-HCC[22.5(29.2)vs 16(20.3)units,P<0.001)and positively associated with BCLC stage[stage 0:13.9(10.8);stage A:17.1(16.8);stage B:19.6(22.3);stage C:32.2(30.8);stage D:45.3(86.6)units,P<0.001]and tumor dimensions[very early:13.9(10.8);intermediate:19.6(18.4);advanced:29.1(33.6)units,P=0.004].However,the discriminative ability for HCC diagnosis was relatively low[AUC(95%CI):0.623(0.570-0.675)].Kaplan-Meier analysis showed that the detection of GP73 in patients with compensated cirrhosis at baseline,was prognostic of higher rates of decompensation(P=0.036),HCC development(P=0.08),and liver-related deaths(P<0.001)during follow-up.CONCLUSION GP73 alone appears efficient for detecting cirrhosis and superior to APRI determination.In combination with APRI,its diagnostic performance can be further improved.Most importantly,the simple GP73 measurement proved promising for predicting a worse outcome of patients with both viral and nonviral chronic liver diseases.Nikolaos K Gatselis Tamás Tornai Zakera Shums Kalliopi Zachou Asterios Saitis Stella Gabeta Roger Albesa Gary L Norman Mária Papp George N Dalekos 2020World Journal of Gastroenterology2020,26,34:21
2H pylori (CagA) and Epstein-Barr virus infection in gastric carcinomas:Correlation with p53 mutation and c-Myc,Bcl-2 and Bax expression显示文摘AIM: To investigate the interrelationship between H pylori and Epstein-Barr virus (EBV) infection in the gastric carcinogenesis having in focus the p53 mutation and the c-Myc, Bcl-2 and Bax expression. METHODS: seventy-one gastric carcinoma tissues were assessed by polymerase chain reaction (PCR) for H pylori and in situ hybridization for EBV. c-Myc, Bcl-2 and Bax expression were detected by immunohistochemistry and single-stranded conformational polymorphism (SSCP) for p53 mutation. RESULTS: The positivity rates for H pylori and EBV were 94.4% and 8.45%, respectively. The majority of the cases displayed only the H pylori presence. All EBV positive cases were also H pylori positive. None infectious agent was observed in 5.55% of the cases. The intestinal type tumor was more frequent in the co-infected and non-infected groups. The female predominated in the non-infected group showing statistical significance (70.4% vs 29.6%, P=0.039). The Bcl-2 was only detected in the group exclusively infected by H pylori. However, c-Myc and Bax were detected in the three groups but with a low frequency in the co-infected group. Mutation of p53 was present in all groups, with the highest frequencies in the H pylori positive groups. CONCLUSION: The frequency of H pylori infection in gastric carcinomas was high. The presented data indicated that gastric carcinogenesis has different pathways depending of the presence of the two investigated infectious agents, suggesting a possible involvement of H pylori with apoptotic process. The low expression of c-Myc and Bax in the EBV-positive groups suggests that EBV may inhibit the expression of these proteins. Nevertheless, p53 mutation shows to be a relevant alteration, independent of both infectious agents.Valeska Portela Lima Marcos Antonio Pereira de Lima Angela Rosa André Márcia Valéria Pitombeira Ferreira Marcos Aurélio Pessoa Barros Sílvia Helena Barem Rabenhorst 2008World Journal of Gastroenterology2008,14,6:17
3Diabetes-related alterations in the enteric nervous system and its microenvironment显示文摘Gastric intestinal symptoms common among diabetic patients are often caused by intestinal motility abnormalities related to enteric neuropathy. It has recently been demonstrated that the nitrergic subpopulation of myenteric neurons are especially susceptible to the development of diabetic neuropathy. Additionally, different susceptibility of nitrergic neurons located in different intestinal segments to diabetic damage and their different levels of responsiveness to insulin treatment have been revealed. These findings indicate the importance of the neuronal microenvironment in the pathogenesis of diabetic nitrergic neuropathy. The main focus of this review therefore was to summarize recent advances related to the diabetes-related selective nitrergic neuropathy and associated motility disturbances. Special attention was given to the findings on capillary endothelium and enteric glial cells. Growing evidence indicates that capillary endothelium adjacent to the myenteric ganglia and enteric glial cells surrounding them are determinative in establishing the ganglionic microenvironment. Additionally, recent advances in the development of new strategies to improve glycemic control in type 1 and type 2 diabetes mellitus are also considered in this review. Finally, looking to the future, the recent and promising results of metagenomics for the characterization of the gut microbiome in health and disease such as diabetes are highlighted.Mária Bagyánszki Nikolett Bódi 2012World Journal of Diabetes2012,3,5:11
4Interrelationship between chromosome 8 aneuploidy,C-MYC amplification and increased expression in individuals from northern Brazil with gastric adenocarcinoma显示文摘AIM: To investigate chromosome 8 numerical aberra- tions, C-MYC oncogene alterations and its expression in gastric cancer and to correlate these findings with histo- pathological characteristics of gastric tumors. METHODS: Specimens were collected surgically from seven patients with gastric adenocarcinomas. Immu- nostaining for C-MYC and dual-color fluorescence in situ hybridization (FISH) for C-MYC gene and chromosome 8 centromere were performed. RESULTS: All the cases showed chromosome 8 aneu- ploidy and C-MYC amplification, in both the diffuse and intestinal histopathological types of Lauren. No significant difference (P < 0.05) was observed between the level ofchromosome 8 ploidy and the site, stage or histological type of the adenocarcinomas. C-MYC high amplification, like homogeneously stained regions (HSRs) and double minutes (DMs), was observed only in the intestinal-type. Structural rearrangement of C-MYC, like translocation, was observed only in the diffuse type. Regarding C-MYC gene, a significant difference (P < 0.05) was observed between the two histological types. The C-MYC protein was expressed in all the studied cases. In the intestinal- type the C-MYC immunoreactivity was localized only in the nucleus and in the diffuse type in the nucleus and cytoplasm. CONCLUSION: Distinct patterns of alterations between intestinal and diffuse types of gastric tumors support the hypothesis that these types follow different genetic path- ways.Danielle Queiroz Calcagno Mariana Ferreira Leal Aline Damaceno Seabra Andre Salim Khayat Elizabeth Suchi Chen Samia Demachki Paulo Pimentel Assumpcao Mario Henrique Girao Faria Silvia Helena Barem Rabenhorst Márcia Valéria Pitombeira Ferreira Marília de Arruda Cardoso Smith Rommel Rodríguez Burbano 2006World Journal of Gastroenterology2006,12,38:9
5Is autoimmune hepatitis a frequent finding among HCV patients with intense interface hepatitis?显示文摘AIM:To evaluate the overlap of autoimmune hepatitis in hepatitis C virus(HCV)-infected patients with intense interface hepatitis.METHODS:Among 1759 patients with hepatitis C submitted to liver biopsy,92(5.2%) presented intense interface hepatitis.These patients were evaluated regarding the presence of antinuclear antibody(ANA),anti-smooth muscle antibody(SMA) and anti-liver/kidney microsomal antibody(LKM-1),levels of γ-globulin and histological findings related to autoimmune hepatitis(plasma cell infiltrate and presence of rosettes).RESULTS:Among patients with hepatitis C and intense interface hepatitis there was a low prevalence of autoantibodies(ANA=12%,SMA=5%,LKM-1=0%) and the median γ-globulin level was within the normal range.Typical histological findings of autoimmune disease were observed in only two cases(2%).After applying the score for diagnosis of autoimmune hepatitis,only one patient was classified with a definitive diagnosis of autoimmune hepatitis.Since overlap with autoimmune hepatitis was not the explanation for the intense necroinflammatory activity in patients with chronic hepatitis C we sought to identify the variables associated with this finding.The presence of intense interface hepatitis was associated with more advanced age,both at the time of infection and at the time of the biopsy,and higher prevalence of blood transfusion and alcohol abuse.CONCLUSION:Although possible,overlap with autoimmune hepatitis is a very rare association in HCV-infected patients with intense interface hepatitis,an unusual presentation which seems to be related to other host variables.Rosilene G Badiani Vitória Becker Renata M Perez Carla AL Matos Lara B Lemos Valéria P Lanzoni Luis Eduardo C Andrade Alessandra Dellavance Antonio Eduardo B Silva Maria Lucia G Ferraz 2010World Journal of Gastroenterology2010,16,29:7
6Intestinal alkaline phosphatase in the colonic mucosa of children with inflammatory bowel disease显示文摘AIM:To investigate intestinal alkaline phosphatase(iAP) in the intestinal mucosa of children with inflammatory bowel disease(IBD).METHODS:Colonic biopsy samples were taken from 15 newly diagnosed IBD patients and from 10 healthy controls.In IBD patients,specimens were obtainedboth from inflamed and non-inflamed areas.The iAP mRNA and protein expression was determined by reverse transcription-polymerase chain reaction and Western blotting analysis,respectively.Tissue localization of iAP and Toll-like receptor(TLR) 4 was investigated by immunofluorescent staining.RESULTS:The iAP protein level in the inflamed mucosa of children with Crohn's disease(CD) and ulcerative colitis(UC) was significantly decreased when compared with controls(both P < 0.05).Similarly,we found a significantly decreased level of iAP protein in the inflamed mucosa in CD compared with non-inflamed mucosa in CD(P < 0.05).In addition,the iAP protein level in inflamed colonic mucosa in patients with UC was decreased compared with non-inflamed mucosa in patients with CD(P < 0.05).iAP protein levels in the non-inflamed mucosa of patients with CD were similar to controls.iAP mRNA expression in inflamed colonic mucosa of children with CD and UC was not significantly different from that in non-inflamed colonic mucosa with CD.Expression of iAP mRNA in patients with noninflamed mucosa and in controls were similar.Co-localization of iAP with TLR4 showed intense staining with a dotted-like pattern.iAP was present in the inflamed and non-inflamed mucosa of patients with CD,UC,and in control biopsy specimens,irrespective of whether it was present in the terminal ileum or in the colon.However,the fluorescent signal of TLR4 was more pronounced in the colon compared with the terminal ileum in all groups studied.CONCLUSION:Lower than normal iAP protein levels in inflamed mucosa of IBD patients may indicate a role for iAP in inflammatory lesions in IBD.Based on our results,administration of exogenous iAP enzyme to patients with the active form of IBD may be a therapeutic option.Kriszta Molnár dám Vannay Beáta Szebeni Nóra Fanni Bánki Erna Sziksz ron Cseh Hajnalka Gyrffy Péter László Lakatos Mária Papp András Arató Gábor Veres 2012World Journal of Gastroenterology2012,18,25:5
7New serological markers in pediatric patients with inflammatory bowel disease显示文摘The spectrum of serological markers associated with inflammatory bowel disease(IBD)is rapidly growing.Due to frequently delayed or missed diagnoses,the application of non-invasive diagnostic tests for IBD,as well as differentiation between ulcerative colitis(UC)and Crohn’s disease(CD),would be useful in the pediatric population.In addition,the combination of pancreatic autoantibodies and antibodies against Saccharomyces cerevisiae antibodies/perinuclear cytoplasmic antibody(pANCA)improved the sensitivity of serological markers in pediatric patients with CD and UC.Some studies suggested that age-associated differences in the patterns of antibodies may be present,particularly in the youngest children.In CD,most patients develop stricturing or perforating complications,and a significant numberof patients undergo surgery during the disease course.Based on recent knowledge,serum antibodies are qualitatively and quantitatively associated with complicated CD behavior and CD-related surgery.Pediatric UC is characterized by extensive colitis and a high rate of colectomy.In patients with UC,high levels of antiCBir1 and pANCA are associated with the development of pouchitis after ileal pouch-anal anastomosis.Thus,serologic markers for IBD can be applied to stratify IBD patients into more homogeneous subgroups with respect to disease progression.In conclusion,identification of patients at an increased risk of rapid disease progression is of great interest,as the application of early and more aggressive pharmaceutical intervention could have the potential to alter the natural history of IBD,and reduce complications and hospitalizations.Márta Kovács Katalin Eszter Müller Mária Papp Péter László Lakatos Mihály Cs?ndes Gábor Veres 2014World Journal of Gastroenterology2014,20,17:4
8Alleviated mucosal and neuronal damage in a rat model of Crohn's disease显示文摘AIM:To establish a rat model suitable to investigate the repetitive relapsing inflammations(RRI)characteristic to Crohn’s disease.METHODS:Colitis was induced by 2,4,6-trinitrobenzenesulfonic acid(TNBS).RRI were mimicked by repeating administrations of TNBS.Tissue samples were taken from control,once,twice and three times treated rats from the inflamed and adjacent non-inflamed colonic segments at different timepoints during the acute intestinal inflammation.The means of the ulcerated area were measured to evaluate the macroscopic mu-cosal damage.The density of myenteric neurons was determined on whole mounts by Hu C/Hu D immunohistochemistry.Heme oxygenase-1(HO-1)expression was evaluated by molecular biological techniques.RESULTS:TNBS-treated rats displayed severe colitis,but the mortality was negligible,and an increase of body weight was characteristic throughout the experimental period.The widespread loss of myenteric neurons,and marked but transient HO-1 up-regulation were demonstrated after the first TNBS administration.After repeated doses the length of the recovery time and extent of the ulcerous colonic segments were markedly decreased,and the neuronal loss was on a smaller scale and was limited to the inflamed area.HO-1 m RNA level was notably greater than after a single dose and overexpression was sustained throughout the timepoints examined.Nevertheless,the HO-1protein up-regulation after the second TNBS treatment proved to be transient.Following the third treatment HO-1 protein expression could not be detected.CONCLUSION:Experimentally provoked RRI may exert a protective preconditioning effect against the mucosal and neuronal damage.The persistent up-regulation of HO-1 m RNA expression may correlate with this.Petra Talapka Lajos István Nagy Alexandra Pál Marietta Zita Poles Anikó Berkó Mária Bagyánszki László Géza Puskás éva Fekete Nikolett Bódi 2014World Journal of Gastroenterology2014,20,44:3
9The potential application of red mud and soil mixture as additive to the surface layer of a landfill cover system显示文摘Red mud, the by-product of aluminum production, has been regarded as a problematic residue all over the world. Its storage involves risks as evidenced by the Ajka red mud spill,an accident in Hungary where the slurry broke free, flooding the surrounding areas. As an immediate remediation measure more than 5 cm thick red mud layer was removed from the flooded soil surface. The removed red mud and soil mixture(RMSM) was transferred into the reservoirs for storage. In this paper the application of RMSM is evaluated in a field study aiming at re-utilizing waste, decreasing cost of waste disposal and providing a value-added product. The purpose was to investigate the applicability of RMSM as surface layer component of landfill cover systems. The field study was carried out in two steps: in lysimeters and in field plots. The RMSM was mixed at ratios ranging between 0 and 50% w/w with low quality subsoil(LQS) originally used as surface layer of an interim landfill cover. The characteristics of the LQS + RMSM mixtures compared to the subsoil(LQS) and the RMSM were determined by physical–chemical, biological and ecotoxicological methods. The addition of RMSM to the subsoil(LQS) at up to 20% did not result any ecotoxic effect, but it increased the water holding capacity. In addition, the microbial substrate utilization became about triple of subsoil(LQS) after 10 months. According to our results the RMSM mixed into subsoil(LQS) at20% w/w dose may be applied as surface layer of landfill cover systems.Eva Ujaczki Viktória Feigl Mónika Molnár Emese Vaszita Nikolett Uzinger Attila Erdélyi Katalin Gruiz 2016Journal of Environmental Sciences2016,28,6:3
10Tensile and fracture properties of an Mg-RE-Zn alloy at elevated temperatures显示文摘Magnesium alloy EZ10(Mg-RE-Zn) was deformed in tension at temperatures from 20 up to 520 °C. A rapid decrease of the yield and tensile strength with temperature was observed at temperatures higher than 300 °C. On the other hand, ductility of samples rapidly increased in the same temperature range. Light microscopy and scanning electron microscopy was used to reveal the reason for these behaviours. Intermetallic particles in grain boundaries are responsible for excellent mechanical properties at lower temperatures. Diffusional processes occurring at temperatures higher than 300 °C significantly influenced the deformation mechanism as well as the fracture character.TROJANOVZuzanka DONI Tibor LUK Pavel PALEK Peter CHALUPOV Mária TILLOV Eva BASTOVANSKY Ronald 2014Journal of Rare Earths2014,32,6:3

12Structural and molecular features of intestinal strictures in rats with Crohn's-like disease显示文摘AIM: To develop a new rat model we wanted to gain a better understanding of stricture formation in Crohn's disease(CD).METHODS: Chronic colitis was induced locally by the administration of 2,4,6-trinitrobenzenesulfonic acid(TNBS). The relapsing inflammation characteristic to CD was mimicked by repeated TNBS treatments. Animals were randomly divided into control, once, twice and three times TNBS-treated groups. Control animals received an enema of saline. Tissue samples were taken from the strictured colonic segments and also adjacent proximally and distally to its 60, 90 or 120 d after the last TNBS or saline administrations. The frequency and macroscopic extent of the strictures were measured on digital photographs. The structural features of strictured gut wall were studied by light- and electron microscopy. Inflammation related alterations in TGF-beta 2 and 3, matrix metalloproteinases 9(MMP9) and TIMP1 m RNA and protein expression were determined by quantitative real-time PCR and western blot analysis. The quantitative distribution of caspase 9 was determined by post-embedding immunohistochemistry.RESULTS: Intestinal strictures first appeared 60 d after TNBS treatments and the frequency of them increased up to day 120. From day 90 an intact lamina epithelialis, reversible thickening of lamina muscularis mucosae and irreversible thickening of the muscularis externa were demonstrated in the strictured colonic segments. Nevertheless the morphological signs of apoptosis were frequently seen and excess extracellular matrix deposition was recorded between smooth muscle cells(SMCs). Enhanced caspase 9 expression on day 90 in the SMCs and on day 120 also in myenteric neurons indicated the induction of apoptosis. The m RNA expression profile of TGF-betas after repeated TNBS doses was characteristic to CD, TGF-beta 2, but not TGF-beta 3 was up-regulated. Overexpression of MMP9 and down-regulation of TIMP1 were demonstrated. The progressive increase in the amount of MMP9 protein in the strictures was also obvious between days 90 and 120 but TIMP1 protein was practically undetectable at this time.CONCLUSION: These findings indicate that aligned structural and molecular changes in the gut wall rather than neuronal cell death play the primary role in stricture formation.Petra Talapka Anikó Berkó Lajos István Nagy Lalitha Chandrakumar Mária Bagyánszki László Géza Puskás éva Fekete Nikolett Bódi 2016World Journal of Gastroenterology2016,22,22:3

14Diabetes mellitus, revascularization and outcomes in elderly patients with myocardial infarction-related cardiogenic shock显示文摘Background The prognostic role of diabetes mellitus(DM)in elderly patients with myocardial infarction-related cardiogenic shock(MI-CS)remains controversial.Little information exists about the impact of intensive cardiac care unit(ICCU)and revascularization on outcomes of elderly patients with MI-CS.We aimed to assess the prognostic impact of DM according to age in patients with MI-CS,and to analyze the impact ICCU management and revascularization on in-hospital mortality in MI-CS patients at older ages.Methods Discharge episodes with diagnosis of CS associated with MI were selected from the Spanish National Health System’s Basic Data Set.Centers were classified according to their availability of ICCU.Main outcome measured was in-hospital mortality.Results A total of 23,590 episodes of MI-CS were identified,of whom 12,447(52.8%)were in patients aged≥75 years.The impact of DM on in-hospital mortality was different among age subgroups.While in younger patients,DM was associated to a higher mortality risk(0.52 vs.0.47,OR=1.12,95%CI:1.06–1.18,χ^2<0.001),this association became non-significant in older patients(0.76 vs.0.81,χ^2=0.09).Adjusted mortality rate of MI-CS aged≥75 years was lower in patients admitted to hospitals with ICCU(adjusted mortality rate:74.2%vs.77.7%,P<0.001)and in patients undergoing revascularization(74.9%vs.77.3%,P<0.001).Conclusions Prognostic impact of DM in patients with MI-CS was different according to age,with a significantly lower impact at older ages.The availability of ICCU and revascularization were associated with better outcomes in these complex patients.Miquel Gual Albert Ariza-Solé María García Márquez Cristina Fernández JoséL Bernal Francesc Formiga María-Isabel Barrionuevo JoséC Sánchez-Salado Victòria Lorente Júlia Pascual Isaac Llaó Oriol Alegre Angel Cequier Javier Elola 2020Journal of Geriatric Cardiology2020,17,10:2
15Involvement of serum retinoids and Leiden mutation in patients with esophageal, gastric, liver, pancreatic, and colorectal cancers in Hungary显示文摘AIM: To analyze the serum levels of retinoids and Leiden mutation in patients with esophageal, gastric, liver,pancreatic, and colorectal cancers.METHODS: The changes in serum levels of retinoids (vitamin A, α- and β-carotene, α- and β-cryptoxanthin,zeaxanthin, lutein) and Leiden mutation were measured by high liquid performance chromatography (HPLC)and polymerase chain reaction (PCR) in 107 patients (70 males/37 females) with esophageal (0/8), gastric (16/5), liver (8/7), pancreatic (6/4), and colorectal (30/21including 9 patients suffering from in situ colon cancer)cancer. Fifty-seven healthy subjects (in matched groups)for controls of serum retinoids and 600 healthy blood donors for Leiden mutation were used.RESULTS: The serum levels of vitamin A and zeaxanthin were decreased significantly in all groups of patients with gastrointestinal (GI) tumors except for vitamin A in patients with pancreatic cancer. No changes were obtained in the serum levels of α- and β-carotene,α- and β-cryptoxanthin, zeaxanthin, lutein in patients with GI cancer. The prevalence of Leiden mutation significantly increased in all groups of patients with GI cancer.CONCLUSION: Retinoids (as environmental factors)are decreased significantly with increased prevalence of Leiden mutation (as a genetic factor) in patients before the clinical manifestation of histologically different (planocellular and hepatocellular carcinoma, and adenocarcinoma) GI cancer.Gyula Mózsik Gy(o|¨)rgy Rumi András D(o|¨)m(o|¨)t(o|¨)r Mária Figler Beáta Gasztonyi El(?)d Papp Alajos Pár Gabriella Pár József Belágyi Zoltán Matus Béla Melegh 2005World Journal of Gastroenterology2005,11,48:2

17Neuroprotective agents effective against radiation damage of central nervous system显示文摘Ionizing radiation caused by medical treatments,nuclear events or even space flights can irreversibly damage structure and function of brain cells.That can result in serious brain damage,with memory and behavior disorders,or even fatal oncologic or neurodegenerative illnesses.Currently used treatments and drugs are mostly targeting biochemical processes of cell apoptosis,radiation toxicity,neuroinflammation,and conditions such as cognitive-behavioral disturbances or others that result from the radiation insult.With most drugs,the side effects and potential toxicity are also to be considered.Therefore,many agents have not been approved for clinical use yet.In this review,we focus on the latest and most effective agents that have been used in animal and also in the human research,and clinical treatments.They could have the potential therapeutical use in cases of radiation damage of central nervous system,and also in prevention considering their radioprotecting effect of nervous tissue.Mária Lalkovičová 2022Neural Regeneration Research2022,17,9:2
