| 1 | Is the schatzki ring a unique esophageal entity?显示文摘AIM:To study,whether the association of Schatzki rings with other esophageal disorders support one of the theories about its etiology.METHODS:From 1987 until 2007,all patients with newly diagnosed symptomatic Schatzki rings (SRs) were prospectively registered and followed.All of them underwent structured interviews with regards to clinical symptoms,as well as endoscopic and/or radiographic examinations.Endoscopic and radiographic studies determined the presence of an SR and additional morphological abnormalities.RESULTS:One hundred and sixty-seven patients (125 male,42 female) with a mean age of 57.1±14.6 years were studied.All patients complained of intermittent dysphagia for solid food and 113 (79.6%) patients had a history of food impaction.Patients experienced symptoms for a mean of 4.7±5.2 years before diagnosis.Only in 23.4% of the 64 patients who had endoscopic and/or radiological examinations before their first presentation to our clinic,was the SR previously diagnosed.At presentation,the mean ring diameter was 13.9±4.97 mm.One hundred and sixty-two (97%) patients showed a sliding hiatal hernia.Erosive reflux esophagitis was found in 47 (28.1%) patients.Twenty-six (15.6%) of 167 patients showed single or multiple esophageal webs;five (3.0%) patients exhibited eosinophilic esophagitis;and four (2.4%) had esophageal diverticula.Four (7%) of 57 patients undergoing esophageal manometry had nonspecific esophageal motility disorders.CONCLUSION:Schatzki rings are frequently associated with additional esophageal disorders,which support the assumption of a multifactorial etiology.Despite typical symptoms,SRs might be overlooked. | Michaela Müller Ines Gockel Philip Hedwig Alexander J Eckardt Kathrin Kuhr Jochem Knig Volker F Eckardt | 2011 | World Journal of Gastroenterology2011，17，23： | 2 |

| 4 | Triose phosphate export from chloroplasts and cellular sugar content regulate anthocyanin biosynthesis during high light acclimation显示文摘Plants have evolvedmultiple strategies to cope with rapid changes in the environment.During high light(HL)acclimation,the biosynthesis of photoprotective flavonoids,such as anthocyanins,is induced.However,the exact nature of the signal and downstreamfactors forHL induction of flavonoid biosynthesis(FB)is still under debate.Here,we show that carbon fixation in chloroplasts,subsequent export of photosynthates by triose phosphate/phosphate translocator(TPT),and rapid increase in cellular sugar content permit the transcriptional and metabolic activation of anthocyanin biosynthesis during HL acclimation.In combination with genetic and physiological analysis,targeted and whole-transcriptome gene expression studies suggest that reactive oxygen species and phytohormones play only a minor role in rapid HL induction of the anthocyanin branch of FB.In addition to transcripts of FB,sugar-responsive genes showed delayed repression or induction in tpt-2 during HL treatment,and a significant overlapwith transcripts regulated by SNF1-related protein kinase 1(SnRK1)was observed,including a central transcription factor of FB.Analysis of mutants with increased and repressed SnRK1 activity suggests that sugar-induced inactivation of SnRK1 is required for HL-mediated activation of anthocyanin biosynthesis.Our study emphasizes the central role of chloroplasts as sensors for environmental changes as well as the vital function of sugar signaling in plant acclimation. | Max-Emanuel Zirngibl Galileo Estopare Araguirang Anastasia Kitashova Kathrin Jahnke Tobias Rolka Christine Kühn Thomas Nägele Andreas S.Richter | 2023 | Plant Communications2023，4，1： | 1 |

| 6 | Harnessing coherence of area decomposition and semantic shared spaces for task allocation in a robotic fleet显示文摘Task allocation is a fundamental problem in multi-robot systems where heterogeneous robots cooperate to perform a complex mission.A general requirement in a task allocation algorithm is to find an optimal set of robots to execute a certain task.This paper presents the work that harnesses an area decomposition algorithm,and a space-based middleware to facilitate task allocation process in unstructured and dynamic environments.To reduce spatial interference between robots,area decomposition algorithm divides a working area into cells which are then dynamically assigned to robots.In addition,coordination and collaboration among distributed robots are realized through a space-based middleware.For this purpose,the space-based middleware is extended with a semantic model of robot capabilities to improve task selection in terms of flexibility,scalability,and reduced communication overhead during task allocation.In this way a framework which exploits the synergy of area decomposition and semantically enriched space-based approach is created.We conducted performance tests in a specific precision agriculture use case focusing on the utilization of a robotic fleet for weed control introduced in the European Project RHEA–Robot Fleets for Highly Effective Agriculture and Forestry Management. | Domagoj Drenjanac Slobodanka Dana Kathrin Tomic Lukas Klausner Eva Kühn | 2014 | Information Processing in Agriculture2014，1，1： | 1 |
