Efficacy of standardized novel Boswellia serrata extract in the dextran sodium sulfate-induced colitis model - potential use in gut health management

Background: Objective of this study was to evaluate anti-inflammatory properties of a novel standardized Boswellia serrata extract–bsRx (developed using natural excipients and designed to have specific ratio of its major actives, viz. AKBA and BBA) in dextran sodium sulfate (DSS)-induced IBD model in BALB/c mice.Methods: Animals (BALB/c mice) in control (CL) group were administered vehicle; DSS-induced colitis group (DSS group), 2.5 % DSS; and Boswellia serrata group (BS group) received DSS, for inducing colitis, together with a novel standardized extract of Boswellia serrata (41 mg/kg, 4.1 mg/ml solution in distilled water) for 10 days. Reference group (SS group) received DSS with sulfasalazine (30 mg/kg, 3.0 mg/ml suspension in distilled water) for 10 days. Clinical assessment for disease activity index (DAI), histopathological examination and hematological assessments were performed.Results: Treatment with Boswellia serrata showed significant reduction in the DAI score on day 10 compared to the DSS group (2.49±0.93 versus 3.63±0.55, p≤0.05). Body weight (18.54±2.21 gm versus 17.05±3.53 gm) and colon length (6.8±0.9 cm versus 7.6±0.6 cm, p≤0.05) also improved in the BS group compared to DSS group, respectively. Histological scoring of colitis was lower in the BS group (10.1±1.37). There was no difference in leukotriene levels between groups (p>0.05).Conclusions: Treatment with novel Boswellia serrata extract improved colon length, DAI and histological scoring index in DSS-induced colitis in IBD mice models. Our results indicate the promising potential of novel Boswellia extract in IBD and gut health management

Comparison of artifacts between paste and collodion method of electrode application in pediatric EEG

Objectives: Children pose challenges to obtain quality EEG data due to excessive artifact. Collodion is used in EEG electrodes due to its water resistance and strong adhesive qualities. This study was done to evaluate differences in artifacts between the collodion and paste method. Methods: 115 subjects (children age \u3e 3 years) were randomized into paste and collodion groups and artifacts evaluated at baseline and every hour over 30s increments. Age, sleep state, and number of electrodes with artifact were also documented. T-test was performed to determine differences in the various parameters between the two groups. Results: 61 subjects were in the paste group and 54 in the collodion group. Mean of total seconds of artifact from 0 to 24h were 41.8s in paste group versus 30.3s in collodion group (P=0.02). Children \u3e 11 years old had less artifact than younger children from 0 to 24h (24.3 versus 41.2s, P=0.03), and from 24 to 48h (33.1 versus 43.1s, P=0.03). There was a significant effect of sleep vs. awake state recordings on artifact from 0 to 24h (30.3 versus 50.2s, P=0.01). Conclusion: Electrode problems are common with both collodion and paste in prolonged AEEG monitoring. However, for studies less than 24h, collodion may be a better alternative. Significance: Our study provides evidence that in some cases collodion may be a better alternative to paste in terms of decreased artifacts

High density linkage mapping of genomic and transcriptomic SNPs for synteny analysis and anchoring the genome sequence of chickpea

This study presents genome-wide discovery of SNPs through next generation sequencing of the genome of Cicer reticulatum. Mapping of the C. reticulatum sequenced reads onto the draft genome assembly of C. arietinum (desi chickpea) resulted in identification of 842,104 genomic SNPs which were utilized along with an additional 36,446 genic SNPs identified from transcriptome sequences of the aforementioned varieties. Two new chickpea Oligo Pool All (OPAs) each having 3,072 SNPs were designed and utilized for SNP genotyping of 129 Recombinant Inbred Lines (RILs). Using Illumina GoldenGate Technology genotyping data of 5,041 SNPs were generated and combined with the 1,673 marker data from previously published studies, to generate a high resolution linkage map. The map comprised of 6698 markers distributed on eight linkage groups spanning 1083.93 cM with an average inter-marker distance of 0.16 cM. Utility of the present map was demonstrated for improving the anchoring of the earlier reported draft genome sequence of desi chickpea by ~30% and that of kabuli chickpea by 18%. The genetic map reported in this study represents the most dense linkage map of chickpea , with the potential to facilitate efficient anchoring of the draft genome sequences of desi as well as kabuli chickpea varieties

The burden of selected digestive diseases in the United States

AbstractBackground & Aims: Gastrointestinal (GI) and liver diseases inflict a heavy economic burden. Although the burden is considerable, current and accessible information on the prevalence, morbidity, and cost is sparse. This study was undertaken to estimate the economic burden of GI and liver disease in the United States for use by policy makers, health care providers, and the public. Methods: Data were extracted from a number of publicly available and proprietary national databases to determine the prevalence, direct costs, and indirect costs for 17 selected GI and liver diseases. Indirect cost calculations were purposefully very conservative. These costs were compared with National Institutes of Health (NIH) research expenditures for selected GI and liver diseases. Results: The most prevalent diseases were non–food-borne gastroenteritis (135 million cases/year), food-borne illness (76 million), gastroesophageal reflux disease (GERD; 19 million), and irritable bowel syndrome (IBS; 15 million). The disease with the highest annual direct costs in the United States was GERD ($9.3 billion), followed by gallbladder disease ($5.8 billion), colorectal cancer ($4.8 billion), and peptic ulcer disease ($3.1 billion). The estimated direct costs for these 17 diseases in 1998 dollars were $36.0 billion, with estimated indirect costs of$22.8 billion. The estimated direct costs for all digestive diseases were $85.5 billion. Total NIH research expenditures were$676 million in 2000. Conclusions: GI and liver diseases exact heavy economic and social costs in the United States. Understanding the prevalence and costs of these diseases is important to help set priorities to reduce the burden of illness.GASTROENTEROLOGY 2002;122:1500-151

Development of a Pediatric Ebola Predictive Score, Sierra Leone1.

We compared children who were positive for Ebola virus disease (EVD) with those who were negative to derive a pediatric EVD predictor (PEP) score. We collected data on all children <13 years of age admitted to 11 Ebola holding units in Sierra Leone during August 2014-March 2015 and performed multivariable logistic regression. Among 1,054 children, 309 (29%) were EVD positive and 697 (66%) EVD negative, with 48 (5%) missing. Contact history, conjunctivitis, and age were the strongest positive predictors for EVD. The PEP score had an area under receiver operating characteristics curve of 0.80. A PEP score of 7/10 was 92% specific and 44% sensitive; 3/10 was 30% specific, 94% sensitive. The PEP score could correctly classify 79%-90% of children and could be used to facilitate triage into risk categories, depending on the sensitivity or specificity required

Highlights from the IceCube Neutrino Observatory

As IceCube surpasses a decade of operation in the full detector configuration, results that drive forward the fields of neutrino astronomy, cosmic ray physics, multi-messenger astronomy, particle physics, and beyond continue to emerge at an accelerated pace. IceCube data is dominated by background events, and thus teasing out the signal is the common challenge to most analyses. Statistical accumulation of data, along with better understanding of the background fluxes, the detector, and continued development of our analysis tools have produced many profound results that were presented at ICRC2023. Highlights covered here include the first neutrino observation of the Galactic Plane, the first observation of a steady emission neutrino point source NGC1068, new characterizations of the cosmic ray flux and its secondary particles, and a possible new era in measuring the energy spectrum of the diffuse astrophysical flux. IceCube is poised to make more discoveries and drive fields forward in the near future with many novel analyses coming online

A Two-Component Lateral Distribution Function for the Reconstruction of Air-Shower Events in IceTop

The surface component of the IceCube Neutrino Observatory, IceTop, consists of an array of ice-Cherenkov tanks measuring the electromagnetic signal as well as low-energy (∼ GeV) muons from cosmic-ray air showers. In addition, accompanying high-energy (above a few 100 GeV) muons can be observed in coincidence in the deep in-ice detector. A combined measurement of the low- and high-energy muon content is of particular interest for tests of hadronic interaction models as well as for cosmic-ray mass discrimination. However, since IceTop does not feature dedicated muon detectors, an estimation of the low-energy muon component of individual air showers is challenging. In this work, a two-component lateral distribution function (LDF), using separate descriptions for the electromagnetic and muon lateral distributions of the detector signals, is introduced as a new approach for the estimation of low-energy muons in air showers on an event-by-event basis. The principle of the air-shower reconstruction using the two-component LDF, as well as its reconstruction performance with respect to primary energy and number of low-energy muons will be discussed

TXS 0506+056 with Updated IceCube Data

Past results from the IceCube Collaboration have suggested that the blazar TXS 0506+056 is a potential source of astrophysical neutrinos. However, in the years since there have been numerous updates to event processing and reconstruction, as well as improvements to the statistical methods used to search for astrophysical neutrino sources. These improvements in combination with additional years of data have resulted in the identification of NGC 1068 as a second neutrino source candidate. This talk will re-examine time-dependent neutrino emission from TXS 0506+056 using the most recent northern-sky data sample that was used in the analysis of NGC 1068. The results of using this updated data sample to obtain a significance and flux fit for the 2014 TXS 0506+056 "untriggered" neutrino flare are reported
