Mechanisms involved in lipid accumulation and apoptosis induced by 1-nitropyrene in Hepa1c1c7 cells

2011

International audience; 1-Nitropyrene (1-NP) is a nitro-polycyclic aromatic hydrocarbon (nitro-PAH) present in diesel exhaust and bound to particular matter in urban air. We show that 1-NP and the referent PAH benzo(a)pyrene (BP) induce apoptosis and a lipid accumulation dependent on cytochrome P450 1A1-metabolites in mouse hepatoma cells, whereas 1-amino-pyrene had no effect. The caspase inhibitor, N-benzyloxycarbonyl-Val-Ala-Asp(O-Me) fluoromethyl ketone (Z-VAD-fmk), inhibits 1-NP-induced apoptosis, but failed to alter 1-NP-triggered lipid accumulation determined by Nile red staining. We further show that cholesterol and fatty acid contents are modified after nitro-PAH exposure and that 1…

Cerebrospinal fluid glucose and lactate concentrations after traumatic brain injury

2021

El estudio del metabolismo cerebral mediante el uso de la microdiálisis en el paciente con traumatismo craneoencefálico (TCE) ha puesto de manifiesto que un descenso a nivel cerebral en la concentración de glucosa o un ascenso de los niveles de lactato son marcadores de alteraciones en el metabolismo cerebral. Aun así, la microdiálisis no es una técnica de uso rutinario en la práctica clínica habitual en el momento actual y existen pocos datos y estudios acerca de las concentraciones de glucosa y lactato en líquido cefalorraquídeo (LCR) de estos pacientes. Este estudio analiza la relación entre los niveles de glucosa y lactato en LCR y el pronóstico de los pacientes tras el TCE. In patients…

LIPOCORISTOMA DELL’ANGOLO PONTO-CEREBELLARE: UN NUOVO NOME PER UNA VECCHIA CONOSCENZA

2019

SCOPO DEL LAVORO: I lipochoristomi sono rari tumori benigni (0.1% di tutti i processi espansivi dell’angolo ponto-cerebellare) che in passato si riteneva derivassero dalle cellule della primitiva meninge e pertanto venivano definiti come lipomi dell’angolo ponto-cerebellare (o del condotto uditivo interno). Oggigiorno sono più propriamente definiti come "coristomi lipomatosi" (o lipocoristomi) poiché si è dimostrato che originano dal tessuto mesenchimale proprio del nervo vestibolo-cocleare. Scopo del presente lavoro è quello di presentare dei casi di lipocoristoma alla luce dei dati oggi riportati nella più recente letteratura. MATERIALI E METODI: Saranno presentati casi di pazienti con ri…

99mTechnetium-Mercaptoacetyltriglycin (MAG3) zum Nachweis von Nierenveränderungen nach extrakorporaler Stoßwellenlithotripsie

1992

Extracorporeal shock wave lithotripsy (ESWL) has become the treatment of choice for urinary calculi. 117 patients were studied prospectively with 99mTc mercaptoacetyltriglycine (MAG3) before and after ESWL. 79 (66%) of the 119 kidneys treated had abnormal findings. Of these 63/119 (53%) had abnormal scans. 41 (65%) had focal lesions with a delayed intrarenal transport. The remaining 22 had a diffuse delay of intrarenal transport. A loss of relative renal function of 3% and more compared to the pretreatment values was observed in 50/119 (42%) patients. 99mTc MAG3 should be done routinely together with radiologic tests (CT or MRI) before and after ESWL to select the patients at risk for post …
