The effect of melatonin in functional heartburn: A randomized, placebo-controlled clinical trial

Open j.urnal of Gastroenterology 2014年第2期4卷 56-61页

Peters VA Medical Center Mount Sinai School of Medicine New York USA King’s County Hospital New York USA North Shore University Hospital at Forest Hills Forest Hills USA

Background: Melatonin is a safe and effective treatment for patients with functional pain and gastrointestinal disorders. Obj.ctive: To evaluate the efficacy and safety of melatonin for 3 months in patients with functional heartburn. Methods: In the randomized, placebo-controlled pilot study, patients with functional heartburn were treated with omeprazole 20 mg before breakfast and randomized to receive either melatonin 6 mg (n = 20), nortripty line 25 mg (n = 20), or placebo (n = 20) at bedtime for 3 months. Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQOL) scores were assessed at baseline and at the end of the study. Results: Melatonin improved GERD-HRQOL scores compared with nortriptyline (P = 0.0015) and placebo (P < 0.0001). Fewer adverse events were reported by patients receiving melatonin compared with those receiving nortriptyline or placebo. Conclusions: Melatonin was a safe and effective treatment for functional heartburn.

Remote Sensing of Selected Winter and Spring Host Plants of Tarnished Plant Bug (Heteroptera: Miridae) and Herbicide Use Strategies as a Management Tactic

American j.urnal of Plant Sciences 2015年第8期6卷 1313-1327页

Remote sensing was used in a series of experiments over a three-year period to obtain spectral reflectance data for studying differences in vegetation indices between grasses, broadleaf plants, and grass/broadleaf plant mixtures. Selected non-crop winter and spring host plants of tarnished plant bug, Lygus lineolaris, were planted in field-plot experiments. Multispectral reflectance data were aerially acquired with both a Real-Time Digital Airborne Camera System (RDACS) sensor and Geospatial Systems (Duncan Tech) MS-2100 multispectral camera. The following six vegetation indices of spectral reflectance were evaluated in this study: normalized difference vegetation index, ratio vegetation index, green normalized difference vegetation index, green vegetation index, green ratio vegetation index, and Ashburn vegetation index. Vegetation indices calculated with imagery data for the grasses and broadleaves differed significantly;there appeared to be more discriminating differences between vegetation indices for grasses and broadleaf plants when the indices were based on a combination of green and near infrared or green and red spectral bands than when the indices were based on red and near infrared spectral bands. Insect data from these studies confirm that tarnished plant bug prefers broadleaf host plants, but can use Italian ryegrass for food and reproduction. The narrow temporal window of host suitability for Italian ryegrass may limit its significance. Herbicide destruction of broadleaf host plants in early spring prevented the tarnished plant bug population increases that occurred in untreated plots. Findings of this study would be useful in site-specific vegetation management decisions in programs such as the prototypical area-wide tarnished plant bug management experiment conducted in the Delta region of Mississippi.

Dear Editor,Transcription factors （TFs） are proteins that regulate the expression of target genes by binding to specific cis-elements in pro-moter regions. Transcriptional regulators （TRs） a）so regulate the expression of target genes; however, they operate indirectly via interaction with the basal transcription apparatus （e.g., TFs）, or by altering the accessibility of DNA to TFs via chromatin remodeling. Another type of regulatory proteins, protein kinases （PKs）,

Predictors of Malignant Pathology and the Role of Trans-Thoracic Needle Biopsy in Management of Solitary Fibrous Tumors of the Pleura: A 30-Year Review of a Tertiary Care Center Patient Cohort

引用

Open j.urnal of Thoracic Surgery 2016年第4期6卷 57-69页

作者： Anna McGuire patrick j. Villeneuve Harman Sekhon Sebastien Gilbert Sudhir Sundaresan Donna E. Maziak Andrew E. j. Seely Farid M. Shamj.

Background: Solitary fibrous tumors of the pleura (SFTP) are rare neoplasms with unpredictable behavior. Lack of unifying criteria for benign or malignant SFTP has resulted in reports of SFTP exhibiting malignant behavior years after complete surgical resection (despite benign initial diagnosis). Additionally, the role of trans-thoracic needle biopsy in initial management of SFTP is unclear. Understanding predictors of malignancy identifies patients at unacceptably high risk for non-surgical primary therapy, and for recurrence despite complete surgical resection. Obj.ctives: The primary obj.ctives were to identify clinicopathological predictors of malignancy & recurrence in SFTP. The secondary aim was to determine the role of trans-thoracic needle biopsy in the management decision algorithm of SFTP. Methods: Retrospective chart review was conducted (j.n. 1983-Dec. 2013) at the Ottawa Hospital for pathologically confirmed SFTP. Data were collected on biopsy-related, clinical, histopathological & immunohistochemistry (IHC) variables. Appropriate tests of statistical inference were conducted for all variables. Results: Pathologically confirmed SFTP was identified in 26 cases. Transthoracic needle biopsy was conducted in 22 (84.6%);with 16 (72.7%) biopsies diagnostic of SFTP with IHC;3 (13.6%) being malignant. Primary management was surveillance in 3 and complete surgical resection in 23. Surgical pathology reported 15 (65.2%) benign and 8 (34.8%) malignant cases. Local recurrence occurred in 3 and distant recurrence in 1. Initial pathology was benign in 3 (75%) with recurrence. Clinicopathologic variables analyzed did not predict recurrent disease. IHC features did not differ between malignant & benign pathology significantly. Predictors of malignant pathology included: infiltrative cellular pattern (p = 0.042), nuclear crowding (p = 0.006), tumour necrosis (p 4 mitoses/ 10 high power field (p Conclusion: Because numerous variables analyzed did not predict recurrent di

It is now recognized that nanoscale particulate matter(PM)represents a substantial health hazard for our society,including PM from restaurant *** this study,we explored the use of a transient pulsed plasma in conj.nction with an applied DC bias to treat oil aerosols that closely resemble restaurant(i.e.,charbroiler)smoke *** polyaromatic olefin PAO-4 and soybean oil,we found that a three-order-of-magnitude reduction in particulates(i.e.,99.9%remediation)could be achieved with this ***,the plasma discharge was produced in a 4-in.-diameter cylindrical reactor with a 5-10 ns high voltage(30 kV)pulse generator together with applied DC bias voltages up to 10 *** distribution of nanoparticle sizes was measured using a scanning mobility particle sizer(SMPS)with diameter centered around 225 ***,the main mechanism of remediation occurs in a two-step process in which the oil nanoparticles are first ionized by the free electrons and free radicals in the plasma and then the charged particles are swept out to the sidewalls of the reactor by the applied DC *** believe this general approach opens up new degrees of freedom in the design of electrostatic oil aerosol pollution control devices.
