New strategy for reducing the EHL friction in steel contacts using additive-formed oleophobic boundary films

Friction 2021年第6期9卷 1346-1360页

In this study we present a mechanism for the elastohydrodynamic(EHD)friction reduction in steel/steel contacts,which occurs due to the formation of oleophobic surface boundary layers from common boundary-lubrication *** simple organic additives(amine,alcohol,amide,and fatty acid)with different molecular structures were employed as the model *** was found that the stronger chemisorption at 100℃,rather than the physisorption at 25℃,is more effective in friction reduction,which reaches 22%.What is more,EHD friction reduction was obtained in steel/steel contacts without use of the diamond-like carbon(DLC)coatings with their wetting or thermal effect,which was previously suggested as possible EHD friction reduction mechanism;yet about the same friction reduction of about 20%was obtained here—but with much simpler and less expensive technology,namely with the adsorbed oleophobic surface layers.A small variation in the additive’s molecular structure results in significant changes to the friction,indicating good potential in future EHD lubrication technology,where these additives could be designed and well optimised for notable reduction of the friction losses in the EHD regime.

Inflammatory bowel disease in liver transplanted patients

引用

World Journal of Gastroenterology 2017年第18期23卷 3214-3227页

作者： Tajana Filipec Kanizaj maja Mijic Department of Gastroenterology University Hospital MerkurSchool of MedicineUniversity of Zagreb University Hospital Merkur

Most common hepatobiliary manifestation of inflammatory bowel disease(IBD) are primary sclerosing cholangitis(PSC) and autoimmune hepatitis, ranking them as the main cause of liver transplantation(LT) in IBD setting. Course of pre-existing IBD after LT differs depending on many transplant related factors. Potential risk factors related to IBD deterioration after LT are tacrolimus-based immunosuppressive regimens, active IBD and cessation of 5-aminosalicylates at the time of LT. About 30% patients experience improvement of IBD after LT, while approximately the same percentage of patients worsens. Occurrence of de novo IBD may develop in 14%-30% of patients with PSC. Recommended IBD therapy after LT is equivalent to recommendations to overall IBD patients. Antitumor necrosis factor alpha appears to be efficient for refractory IBD. Due to potential side effects it needs to be applied with caution. In average 9% of patients require proctocolectomy due to medically refractory IBD or colorectal carcinoma. The most frequent complication in patients who undergo proctocolectomy with ileal-pouch anal anastomosis is pouchitis. It is still undeterminable if LT adds to risk of developing pouchitis in PSC patients. Annual colonoscopies are recommended as surveillance and precaution of colonic malignancies.

Language of plants: Where is the word?

引用

Journal of Integrative Plant Biology 2016年第4期58卷 343-349页

作者： maja impraga Junji Takabayashi Jarmo K.Holopainen Botanical Garden Faculty of Science Ghent University Department of Environmental Science University of Eastern Finland Center for Ecological Research Kyoto University

Plants emit biogenic volatile organic compounds（BVOCs） causing transcriptomic, metabolomic and behavioral responses in receiver organisms. Volatiles involved in such responses are often called ＂plant language＂. Arthropods having sensitive chemoreceptors can recognize language released by plants. Insect herbivores, pollinators and natural enemies respond to composition of volatiles from plants with specialized receptors responding to different types of compounds. In contrast, the mechanism of how plants＂hear＂ volatiles has remained obscured. In a plant-plant communication, several individually emitted compounds are known to prime defense response in receiver plants with a specific manner according to the chemical structure of each volatile compound. Further, composition and ratio of volatile compounds in the plant-released plume is important in plantinsect and plant-plant interactions mediated by plant volatiles. Studies on volatile-mediated plant-plant signaling indicate that the signaling distances are rather short, usually not longer than one meter. Volatile communication from plants to insects such as pollinators could be across distances of hundreds of meters. As many of the herbivore induced VOCs have rather short atmospheric life times, we suggest that in long-distant communications with plant volatiles,reaction products in the original emitted compounds may have additional information value of the distance to emission source together with the original plant-emitted compounds.

Molecular heterogeneity of gelatin-binding proteins from human seminal plasma

引用

Asian Journal of Andrology 2010年第3期12卷 363-375,I0010页

作者： maja M. Kosanovic Miroslava M. Jankovic Department for Immunochemistry and Glycobiology Institute for the Application of Nuclear Energy-INEP University of Belgrade Banatska 31b Zemun-Belgrade 11080 Serbia

Defining the molecular characteristics of seminal plasma proteins is essential for understanding their function in physiological and pathological conditions. Starting from the predicted importance of human seminal plasma gelatin-binding proteins, comprising fibronectin （FN） and FN-related molecules, for male fertility, this study aims at gaining insight into their immuno-glycobiochemical properties. Human seminal plasma from subjects with normal semen parameters were separated on a gelatin-Sepharose column and analyzed by sodium dodecyl sulfate- polyacrylamide gel electrophoresis and immunoblotting using antibodies against distinct FN forms. Heterogeneity of the isolated molecular species was examined by protein chip arrays combined with surface-enhanced laser desorption/ionization time of flight mass spectrometry, on normal, metal and hydrophobic surfaces. Carbohydrate composition was investigated using mannose-, fucose- and sialic acid-specific plant lectins and galectin-1. The results obtained indicated a pattern of isolated proteins corresponding to that of known FN fragments, as confirmed by immunoreactivity. Among them heparin-binding ability was preferentially associated with low molecular mass species. As for posttranslational modifications, phosphorylation and glycosylation of distinct fragments were revealed. Lectin binding to fragments containing the gelatin-binding domain, particularly with Ricinus communis agglutinin I, was stronger than to fragments containing the cell-binding site of FN. A low level of sialylation and distinctive concanavalin A- and Lens culinaris agglutinin-reactive species were also observed. Galectin-1 did not interact with the isolated preparation. Resolving the molecular heterogeneity of normal human seminal plasma FN and gaining initial insight into possible similarities/differences with known FN molecular species may be considered a prerequisite step preceding challenging the clinical usefulness of these molecular properties.

Background This study systematically reviewed etiology, prevalence, treatment and outcome of Barrett's esophagus (BE) in the pediatric population. Methods PubMed? was searched for terms 'Barrett's esophagus' and 'children'. End points were age of patients, etiology, association with other syndromes, treatment, incidence of carcinoma and outcome. This review was conducted according to the PRISMA guidelines. Data were collected, entered and analyzed into a Microsoft Excel? spreadsheet database. Results Search revealed 278 articles published between 1984 and 2017, of which 18 met the inclusion criteria. There were 130 patients for analysis with a mean age 10.6 years (0.8–17.2 years). BE was diagnosed in 80 patients with confirmed gastroesophageal reflux (GER) only;further 20 patients were neurologically impaired and had GER, 13 after esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) repair with associated GER, 6 post-chemotherapy, 1 after post caustic burns, 1 after esophageal replacement with stomach, 1 after peptic esophageal stricture, 1 with secretory diarrhea, 1 with Fanconi anemia, 1 tetralogy of Fallot, and 5 healthy children. Regarding treatment, 26 were on medical treatment only, 16 had surgeries combined with medical treatment, 80 patients underwent surgery only, 1 was on diet management, 4 were on surveillance only and 2 were never treated for BE as death occurred because of associated conditions. Fundoplication was the most commonly performed surgery (82.2%). Adenocarcinoma was found in one 23-year-old patient. Mean follow-up was 3.45 years (10 months–13 years) and long-term outcome showed recurrences in 8 and esophago-mediastinal fistula and proximal esophagus ulcer in 1. There were 7 lethal outcomes which were not directly associated with BE. Conclusions Although BE is considered a premalignant condition;incidence of carcinoma in pediatric population is low. Long-term follow-up with endoscopies and biopsies seems to be advisable for
