Outlining key inflammation-associated parameters during early phase of an experimental gram-negative sepsis model in rhesus macaques(macaca mulatta)

Animal models and Experimental medicine 2019年第4期2卷 326-333页

The aim of this study was to identify inflammation-associated markers during the early phase of sepsis in rhesus macaque. Four rhesus macaques were given an intravenous dose of 1010 CFU/kg of E. coli. Blood samples were collected before, or 30 minutes, 2, 4, 6 and 8 hours after E. coli infusion. Physiological parameters, bacteremia, endotoxemia, C-reactive protein(CRP), procalcitonin(PCT), and plasma cytokines/chemokines were determined for each animal. Bacteremia was present in all animals from 30 minutes to 3 hours after E. coli infusion whereas endotoxin was detected during the full-time course. CRP and PCT levels remained at detectable levels during the whole experimental window suggesting an ongoing inflammatory process. Signature cytokines and chemokines such as TNF-α, mIP-1α, and mIP-1β peaked about 2 hours after E. coli infusion and decreased thereafter. Plasma IL-6, IL-12 p40, IFN-γ, and IL-1 Ra, as well as I-TAC, mIG, IP-10 and mCP-1, remained at detectable levels after 4 hours of E. coli infusion. This nonhuman primate model could be useful for the assessment of new therapeutics aiming to suppress key inflammatory markers throughout sepsis early phases.

AIm： To determine whether different intravitreal doses of quinupristin/dalfopristin lead to electroretinographic or histological changes in the rabbit retina over one month period after injection. mETHODS： Eighteen New Zealand white rabbits were divided into three treatment groups （groups 1 to 3） and different intravitreal doses of quinupristin/dalfopristin were tested in each group. The right eye was injected with the drug and the left eye received intravitreal injection of 5% dextrose water and served as control eye. The doses delivered to each group were 0.1 mg/0.1 mL, 1 mg/0.1 mL and 10 mg/0.1 mL. Simultaneous, bilateral, dark-adapted electroretinography and clinical images of both eyes were obtained in all groups before injection （baseline） and after 7, 14, 21 and 28d, followed by enucleation for histological examination. RESULTS： Subjects in the group 1 showed no signs of toxicity in the electroretinogram when compared with groups 2 and 3 （Kruskall-Wallis test, P=0.000）. By day 7, no electrical response to light stimuli was recorded in the treated eyes in groups 2 and 3, consistent with severe damage due to retinal toxicity. Light microscopy revealedno significant histopathological changes in the group 1, while rabbits in groups 2 and 3 had signs of granulomatous inflammation in most cases. CONCLUSION： Intravitreal 0.1 mg/0.1 mL doses of quinupristin/dalfopristin do not lead to electroretinographic or histological signs of retinal toxicity compared with 1 mg/0.1 mL and 10 mg/O.1 mL in this rabbit model.

manufacture of Industrial Refractory Crucibles Based on Clays from Burkina Faso

引用

Journal of minerals and materials Characterization and Engineering 2024年第2期12卷 79-90页

作者： Kassoum Barry Youssouf Sawadogo moustapha Sawadogo Brahima Sorgho mohamed Seynou Boubié guel Philippe Blanchart Lamine Zerbo Laboratory of molecular Chemistry and materials (LC2m) University Joseph KI-ZERBO Ouagadougou Burkina Faso Institute of Research for Ceramic (IRCER) European Ceramic Centre (CEC) Limoges France

In Burkina Faso, one of the three largest gold producers in West Africa, foundry activity is often paralyzed when basic equipment such as crucibles and cups are not available or should be imported. However, previous studies have shown the availability of kaolinite-rich clay resources that could be used for the local manufacture of silico-aluminous ceramic crucibles. This work allowed to manufacture industrial ceramic crucibles with local clays and then they were tested in foundry industry. The materials were manufactured from three (03) raw materials including two clays (SAB and ROU) and sand. The chemical and mineral analysis has shown that the raw materials are suitable for the formulation of refractory materials. The results of characterization of the materials formulated showed that the properties of use are appreciable. The porosity of the materials is relatively low (23 - 28 vol%) with a diametral compressive strength between 0.61 and 1.34 mPa. Crucibles sintered at 1250˚C with a stay of 2 hours have a mechanical strength capable of supporting the weight of the ores contained. These crucibles have a refractoriness under load (T0.5) above 1141˚C and resist chemical attacks. Tests were carried out in the industry at 1100˚C, and the results were satisfactory.

S-adenosyl-methionine decreases ethanol-induced apoptosis in primary hepatocyte cultures by a c-Jun N-terminal kinase activity-independent mechanism

引用

World Journal of Gastroenterology 2006年第12期12卷 1895-1904页

作者： maria del Pilar Cabrales-Romero Lucrecia márquez-rosado Samia FatteI-Fazenda Cristina Trejo-Solis Evelia Arce-Popoca Leticia Alemán-Lazarini Saúl Villa-Trevineo Department of Cell Biology Centro de Investigacién y Estudios Avanzados IPN Av. IPN No. 2508 México DF México Department of Neuroimmunology Instituto National de Neurologia y Neurocirugia MVS Insurgentes Sur 3877 Col La Fama DF México

AIm： To determine the role of c-Jun N-terminal kinase （JNK） activity in ethanol-induced apoptosis and the modulation of this signaling cascade by S-Adenosylmethionine （Adomet）. mETHODS： Primary hepatocyte cultures were pretreated with 100 IJmol/L SP600125, a selective JNK inhibitor, 1 mL/L DmSO or 4 mmol/L Adomet and then exposed to 100 mmo/L ethanol. Hepatocyte apoptosis was determined by the TUNEL and DNA ladder assays. JNK activity and its inhibition by SP600125 and Adomet were determined by Western blot analysis of c-jun phosphorylation and Bid fragmentation. SP600125 and Adomet effects on the apoptotic signaling pathway were determined by Western blot analysis of cytochrome c release and pro-caspase 3 fragmentation. The Adomet effect on glutathione levels was measured by EIIman＇s method and reactive oxygen species （ROS） generation by cell cytometry. RESULTS： The exposure of hepatocytes to ethanol induced JNK activation, c-jun phosphorylation, Bid fragmentation, cytochrome c release and pro-caspase 3 cleavage; these effects were diminished by SP600125, and caused a significant decrease in ethanol-induced apoptosis （P〈 0.05）. Adomet exerted an antioxidant effect maintaining glutathione levels and decreasing ROS generation, without a significant effect on JNK activity, and prevented cytochrome c release and pro-caspase 3 cleavage.CONCLUSION： The JNK signaling cascade is a key component of the proapoptotic signaling pathway induced by ethanol. JNK activation may be independent from ROS generation, since Adomet which exerted antioxidant properties did not have a significant effect on JNK activity. JNK pathway modulator agents and Adomet may be components of promising therapies for alcoholic liver disease （ALD） treatment.
