yet been addressed by longitudinal magnetic resonance (MR) spectroscopic experiments. Therefore, we longitudinally characterized cerebral metabolite changes in 15 healthy individuals by proton magnetic resonance spectroscopy ((1)H-MRS) subsequent to the ingestion of a standard beverage (mean peak blood alcohol concentration (BAC): 51.43 +/- 10.27 mg/dL). Each participant was examined before, over 93.71 +/- 11.17 mins immediately after and 726.36 +/- 94.96 mins (12.11 +/ -1.58 h) past per os alcohol exposure. Fronto-mesial and cerebellar ethanol concentrations over time were similar as determined by the LCModel analysis of spectral data. Alcohol-induced changes of fronto-mesial creatine, choline, glucose, inositol and aspartate levels at 5.79 +/- 2.94 [corrected] mins upon ingestion as well as cerebellar choline and inositol levels at 8.64 +/- 2.98 [corrected] mins past exposure. Closely associated with ethanol concentrations, supratentorial creatine, choline, inositol and aspartate levels decreased after ethanol administration, whereas glucose levels increased. Similarly, infratentorial choline and inositol concentrations were negatively correlated with ethanol levels over time. There were no changes in N-acetyl-aspartate levels upon alcohol exposure. Furthermore, no influence of ethanol on brain water integrals was detected. Ethanol consumption may directly increase oxidative stress and the neuronal vulnerability to it. In addition, our results are compatible with ethanol-induced cell membrane modifications and alternative energy substrate usage upon alcohol exposure.", "keywords" : [ { "otype" : "Keyword", "mtid" : 52, "link" : "/api/keyword/52", "label" : "Adult", "published" : true, "oldId" : 52, "snippet" : true }, { "otype" : "Keyword", "mtid" : 56, "link" : "/api/keyword/56", "label" : "Female", "published" : true, "oldId" : 56, "snippet" : true }, { "otype" : "Keyword", "mtid" : 61, "link" : "/api/keyword/61", "label" : "Middle Aged", "published" : true, "oldId" : 61, "snippet" : true }, { "otype" : "Keyword", "mtid" : 62, "link" : "/api/keyword/62", "label" : "Male", "published" : true, "oldId" : 62, "snippet" : true }, { "otype" : "Keyword", "mtid" : 65, "link" : "/api/keyword/65", "label" : "Humans", "published" : true, "oldId" : 65, "snippet" : true }, { "otype" : "Keyword", "mtid" : 4905, "link" : "/api/keyword/4905", "label" : "Time Factors", "published" : true, "oldId" : 4905, "snippet" : true }, { "otype" : "Keyword", "mtid" : 8249, "link" : "/api/keyword/8249", "label" : "Young Adult", "published" : true, "oldId" : 8249, "snippet" : true }, { "otype" : "Keyword", "mtid" : 9384, "link" : "/api/keyword/9384", "label" : "Ethanol/*pharmacology", "published" : true, "oldId" : 9384, "snippet" : true }, { "otype" : "Keyword", "mtid" : 15664, "link" : "/api/keyword/15664", "label" : "Magnetic Resonance Spectroscopy", "published" : true, "oldId" : 15664, "snippet" : true }, { "otype" : "Keyword", "mtid" : 1003763, "link" : "/api/keyword/1003763", "label" : "Longitudinal Studies", "published" : true, "oldId" : 1003763, "snippet" : true }, { "otype" : "Keyword", "mtid" : 1085465, "link" : "/api/keyword/1085465", "label" : "Central Nervous System Depressants/*pharmacology", "published" : true, "oldId" : 1085465, "snippet" : true }, { "otype" : "Keyword", "mtid" : 1483985, "link" : "/api/keyword/1483985", "label" : "Brain/*drug effects/enzymology/*metabolism", "published" : true, "oldId" : 1483985, "snippet" : true } ], "digital" : null, "printed" : null, "sourceYear" : 2018, "packet" : "362763", "foreignEdition" : true, "foreignLanguage" : true, "fullPublication" : true, "conferencePublication" : false, "nationalOrigin" : true, "missingAuthor" : false, "oaType" : "NONE", "oaCheckDate" : "2024-02-19", "oaFree" : false, "oaByAuthor" : { "otype" : "Admin", "mtid" : 10003132, "link" : "/api/admin/10003132", "label" : "Balázs András (MTMT Központ, admin)", "familyName" : "Balázs", "givenName" : "András", "published" : true, "oldId" : 10003132, "snippet" : true }, "citationCount" : 26, "citationCountUnpublished" : 0, "citationCountWoOther" : 26, "independentCitCountWoOther" : 24, "nationalOriginCitationCount" : 0, "foreignEditionCitationCount" : 26, "doiCitationCount" : 25, "wosCitationCount" : 26, "scopusCitationCount" : 20, "wosScopusCitationCount" : 26, "wosScopusCitationCountWoOther" : 26, "wosScopusIndependentCitationCount" : 24, "wosScopusIndependentCitationCountWoOther" : 24, "independentCitationCount" : 24, "selfCitationCount" : 2, "unhandledCitationCount" : 0, "citingPubCount" : 26, "independentCitingPubCount" : 24, "citingPubCountWoOther" : 26, "independentCitingPubCountWoOther" : 24, "unhandledCitingPubCount" : 0, "citedPubCount" : 2, "citedCount" : 2, "ratings" : [ { "otype" : "SjrRating", "mtid" : 5810301, "link" : "/api/sjrrating/5810301", "label" : "sjr:D1 (2009) Scopus - Neurology (clinical) JOURNAL OF CEREBRAL BLOOD FLOW AND METABOLISM 0271-678X 1559-7016", "listPos" : 30, "rankValue" : 0.1, "type" : "journal", "ratingType" : { "otype" : "RatingType", "mtid" : 10002, "link" : "/api/ratingtype/10002", "label" : "sjr", "code" : "sjr", "published" : true, "snippet" : true }, "subject" : { "otype" : "ClassificationExternal", "mtid" : 2728, "link" : "/api/classificationexternal/2728", "label" : "Scopus - Neurology (clinical)", "published" : true, "oldId" : 2728, "snippet" : true }, "ranking" : "D1", "calculation" : "DIRECT", "published" : true, "oldId" : 5810301, "snippet" : true } ], "ratingsForSort" : "D1", "hasCitationDuplums" : false, "userChangeableUntil" : "2019-01-31T22:59:00.000+0000", "publishDate" : "2018-10-02T07:43:53.000+0000", "directInstitutesForSort" : "", "ownerAuthorCount" : 1, "ownerInstituteCount" : 2, "directInstituteCount" : 0, "authorCount" : 5, "contributorCount" : 0, "hasQualityFactor" : true, "link" : "/api/publication/3404551", "label" : "Biller A et al.
