1可逆热致变色油墨的色度学特性研究显示文摘本文研究了活化温度为31℃的3种含隐色染料基的热致变色油墨的色度学特性。这3种油墨具有相似的颜料粒径分布和同等厚度且对氧等离子体腐蚀相对稳定的微胶囊壳。油墨颜色与温度、引起颜色滞后的样品热史两个因素有关。比较脱色和着色过程,在CIELAB色空间中所观测的滞后环面积决定了样品上色差的大小。同一样品所能达到的最大色差是由样品不同的热史和温度决定。4个特征温度描述了引起颜色滞后的2个化学反应。当冷却到低于活化温度时,脱色状态的稳定性超过10h。热致变色效应的可逆性随着最高加热温度约呈线性降低。Rahela Kular Moja Frikovec Nina Hauptman Alenka Vesel Marta Klanjek Gunde 柳玲 2010中国印刷与包装研究2010,2,3:6
2Pentadecapeptide BPC 157 resolves suprahepatic occlusion of the inferior caval vein, Budd-Chiari syndrome model in ratsPentadecapeptide BPC 157 resolves suprahepatic occlusion of the inferior caval vein, Budd-Chiari syndrome model in rats显示文摘BACKGROUND Recently,as a possible therapy resolving solution,pentadecapeptide BPC 157 therapy,has been used in alleviating various vascular occlusion disturbances.BPC 157 was previously reviewed as novel mediator of Robert cytoprotection and endothelium protection in the stomach,and gut-brain axis,beneficial therapy in gastrointestinal tract,with particular reference to vascular recruitment,ulcerative colitis and tumor cachexia,and other tissues healing.Here we raised new hypothesis about BPC 157 therapy in the Budd-Chiari syndrome in rats,rapid bypassing of the suprahepatic inferior caval vein occlusion,and rats recovery with the active and effective pharmacotherapy treatment.AIM To investigate Budd-Chiari syndrome model(inferior caval vein suprahepatic occlusion)resolution,since BPC 157 resolves various rat vascular occlusion.METHODS We assessed the activated bypassing pathways between the inferior and superior caval veins and portocaval shunt,counteracted caval/portal hypertension,aortal hypotension,venous/arterial thrombosis,electrocardiogram disturbances,liver and gastrointestinal lesions(i.e.,stomach and duodenum hemorrhages,in particular,congestion).Rats with suprahepatic occlusion of the inferior vena cava by ligation were medicated at 1 min,15 min,24 h,or 48 h post-ligation.Medication consisted of 10μg/kg BPC 157,10 ng BPC 157 or 5 m L/kg saline,administered once as an abdominal bath or intragastric application.Gross and microscopic observations were made,in addition to assessments of electrical activity of the heart(electrocardiogram),portal and caval hypertension,aortal hypotension,thrombosis,hepatomegaly,splenomegaly and venography.Furthermore,levels of nitric oxide,malondialdehyde in the liver and serum enzymes were determined.RESULTS BPC 157 counteracted increased P wave amplitude,tachycardia and ST-elevation,i.e.,right heart failure from acute thrombotic coronary occlusion.The bypassing pathway of the inferior vena cava-azygos(hemiazygos)vein-superior vena cava and portocaval shunt occurred rapidly.Even with severe caval portal hypertension,BPC 157 antagonized portal and caval hypertension and aortal hypotension,and also reduced refractory ascites.Thrombosis of portal vein tributaries,inferior vena cava,and hepatic and coronary arteries was attenuated.In addition,there was reduced pathology of the lungs(severe capillary congestion)and liver(dilated central veins and terminal portal venules),decreased intestine hemorrhagic lesions(substantial capillary congestion,submucosal edema and architecture loss),and increased liver and spleen weight.During the period of ligation,nitric oxide-and malondialdehyde-levels in the liver remained within normal healthy values,and increases in serum enzymes were markedly reduced.CONCLUSION BPC 157 counteracts Budd Chiari syndrome in rats.Slaven Gojkovic Ivan Krezic Borna Vrdoljak Dominik Malekinusic Ivan Barisic andreja Petrovic Katarina Horvat Pavlov Marijan Kolovrat Antonija Duzel Mario Knezevic Katarina Kasnik Kovac Domagoj Drmic Lovorka Batelja Vuletic Antonio Kokot Alenka Boban Blagaic Sven Seiwerth Predrag Sikiric 2020World Journal of Gastrointestinal Pathophysiology2020,11,1:2
3Female competition for availability of males in insects:the Nezara viridula(Linnaeus,1758)model显示文摘Multimodal communication in solitary stinkbugs enables them to meet,mate and copulate.Many plant-dwelling species exchange information during the calling phase of mating behavior using substrate-borne vibratory signals.A female-biased gender ratio induces rivalry and competition for a sexual partner.Female competition for males,first described among Heteroptera in three stinkbug species,revealed species specific differences and opened the question of plasticity in individually emitted temporal and frequency signal characteristics during calling and rival alternation.To address this question and gain an insight into the mechanisms underlying stinkbug female rivalry,we compared the characteristics of alternated signals in the southern green stinkbug Nezara viridula(Linnaeus,1758)(Hemiptera:Pentatomidae).Compared to male rivalry,female rivalry is more complex,lasts longer and runs through successive phases by a combination of different song types.The male pheromone triggers alternation between females,producing song pulses that occasionally overlap each other.One female initiates the rivalry by changing individual pulses into pulse trains of three different types.The competing female alternates with pulses of changed temporal characteristics at lower levels of rivalry and by varying the frequency characteristics of pulse trains at higher levels.During female rivalry,the male either stops responding or occasionally emits calling and courtship signals in response to the female that has produced signals of steady temporal characteristics.Female rivalry shows complex and species specific patterns of information exchange at different levels with a broad-range variation of temporal and frequency characteristics of,until now,unidentified vibratory emissions.Andrej Cokl Alenka Zunic Kosi Raul Alberto Laumann Meta Virant-Doberlet 2020Insect Science2020,27,4:1

16Pentadecapeptide BPC 157 resolves Pringle maneuver in rats,both ischemia and reperfusion显示文摘BACKGROUND The Pringle maneuver[portal triad obstruction(PTO)]provides huge disturbances during ischemia and even more thereafter in reperfusion.Contrarily,a possible solution may be stable gastric pentadecapeptide BPC 157,with already documented beneficial effects in ischemia/reperfusion conditions.Recently,BPC 157,as a cytoprotective agent,successfully resolved vessel occlusions in rats(ischemic colitis;deep vein thrombosis,superior anterior pancreaticoduodenal vein;bile duct cirrhosis)through rapid collateral vessel recruitment to circumvent vessel occlusion.Thereby,medication BPC 157 regimens were administered as a single challenge before and during ischemia or,alternatively,at various time points during reperfusion.AIM To introduce BPC 157 therapy against pringle maneuver-damage.METHODS In deeply anesthetised rats,the portal triad was clamped up for 30 min.Rats then underwent reperfusion for either 15 min or 24 h.Medication[(10μg,10 ng/kg)regimens,administered as a single challenge]picked(a)ischemia,PTO period[at 5 min before(ip)or at 5 or 30 min of ligation time(as a bath to PTO)]or(b)reperfusion,post-PTO period[at 1 or 15 min(bath during surgery)or 24 h(ip)reperfusion-time].We provided gross,microscopy,malondialdehyde,serum enzymes,electrocardiogram,portal,caval,and aortal pressure,thrombosis and venography assessments.RESULTS BPC 157 counteracts electrocardiogram disturbances(increased P wave amplitude,S1Q3T3 QRS pattern and tachycardia).Rapidly presented vascular pathway(portal vein-superior mesenteric vein-inferior mesenteric vein-rectal veins-left ileal vein-inferior caval vein)as the adequate shunting immediately affected disturbed haemodynamics.Portal hypertension and severe aortal hypotension during PTO,as well as portal and caval hypertension and mild aortal hypotension in reperfusion and refractory ascites formation were markedly attenuated(during PTO)or completely abrogated(reperfusion);thrombosis in portal vein tributaries and inferior caval vein or hepatic artery was counteracted during portal triad obstruction PTO.Also,counteraction included the whole vicious injurious circle[i.e.,lung pathology(severe capillary congestion),liver(dilated central veins and terminal portal venules),intestine(substantial capillary congestion,submucosal oedema,loss of villous architecture),splenomegaly,right heart(picked P wave values)]regularly perpetuated in ischemia and progressed by reperfusion in Pringle rats.CONCLUSION BPC 157 resolves pringle maneuver-damage in rats,both for ischemia and reperfusion.Marijan Kolovrat Slaven Gojkovic Ivan Krezic Dominik Malekinusic Borna Vrdoljak Katarina Kasnik Kovac Tamara Kralj Domagoj Drmic Ivan Barisic Katarina Horvat Pavlov Andreja Petrovic Antonija Duzel Mario Knezevic Ivan Mirkovic Antonio Kokot Alenka Boban Blagaic Sven Seiwerth Predrag Sikiric 2020World Journal of Hepatology2020,12,5:1
