Portobiliary fistulas are rare but may lead to life-threatening complications. Biliary plastic stent-induced portobiliary fistulas during endoscopic retrograde cholangiopancreatography have been described. Herein, we present a case of portal cavernography and recurrent hemobilia after endoscopic retrograde cholangiopancreatography in which a portobiliary fistula was detected in a patient with portal biliopathy. This likely indicates a change in clinical presentation (from bilhemia to hemobilia) after biliary drainage that was successfully treated by placement of a fully covered, self-expandable metallic stent.

A 44-year-old woman underwent sleeve gastrectomy, which was complicated by a leak. She was treated with two sessions ofendoscopic internal drainage using plastic double-pigtail stents. Her clinical evolution was favorable, but four months after the initialstent placement, she became symptomatic, and a gastrobronchial fistula with the proximal end of the stents invading the diaphragmwas diagnosed. She was treated with antibiotics, plastic stents were removed, and a partially covered metallic esophageal stent wasplaced. Eleven weeks later, the esophageal stent was removed with no evidence of fistula. Inappropriate stent size, position, stentingduration, and persistence of low-grade inflammation could explain the patient’s symptoms and provide a mechanism for gradualmuscle rupture and fistula formation. Although endoscopic internal drainage is usually safe and effective for the management ofpost-laparoscopic sleeve gastrectomy leaks, close clinical and radiological follow-up is mandatory.
Evaluation of dietary sources of protein on growth performance in pigs
Mohana Devi, S.,Devi, US,Kim, IH INSTITUTE OF AGRICULTURAL FOOD INFORMATION 2014 VETERINARNI MEDICINA -PRAHA- Vol.59 No.5
<P>A 6-week trial was conducted to investigate the effects of animal skin protein sources from swine and cattle on growth performance, body condition and blood characteristics in growing pigs. A total of 96 pigs (23.50 ± 0.61 kg) were randomly allotted into four dietary treatment groups as follows: (1) basal diet (BD); (2) basal diet with 1.5% hydrolysed render meal (HRM); (3) basal diet with 1.5% swine skin meal (SSM); (4) basal diet with 1.5% cattle hide meal (CHM). There were six replicate pens per treatment with four pigs per pen. The average daily gain (ADG) was improved in response to SSM treatment compared with other treatments (P < 0.05). Pigs fed with HRM, SSM and CHM diets showed increases in average daily feed intake (ADFI) and decreased gain-to-feed (G : F) ratios compared with pigs fed with BD (P < 0.05). There were no differences in dry matter (DM), nitrogen (N), and energy (E) digestibility among treatments. The backfat thickness and lean percentage of pigs was unaffected by the treatments. Similarly, there was no difference in blood characteristics among treatments. In conclusion, the supplementation of SSM in growing pig diets improved the growth rate and Feed Intake (FI), but its usage in swine diets is limited by the poor protein quality. </P>
Genetic Diversity among Indian Oak Tasar Silkworm, Antheraea proylei J. Revealed by ISSR Markers
Devi, Kanghujam Ibsorani,Ponnuvel, Kangayam M.,Singh, Laishram Somen,Singh, Kangjam Chaoba,Dutta, Karabi Korean Society of Sericultural Science 2012 International Journal of Industrial Entomology Vol.24 No.2
The Indian Oak Tasar silkworm, Antheraea proylei J. is a beneficial insect with great economic importance in India for its silk production. In this study, six populations of Antheraea proylei and A. frithi Moore (as an out group) were subjected to inter simple sequence repeat (ISSR) marker analysis in order to assess its genetic diversity. Fifteen ISSR primers produced 91 markers among different breeds of A. proylei and A. frithi of which 89 are polymorphic, generating 97.8% polymorphism. The dendrogram constructed using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) and cluster analysis made using Nei's genetic distance resulted in the formation of one major group containing four sub-groups separating the breeds. This result suggests that ISSR amplification is potentially useful for molecular characterization of oak tasar silkworm genotypes.
Temporal multifractal analysis of extreme events in the crude oil market

The ‘crude oil price’ has been one of the integral components of rising globalization. This paper delves into the static and dynamic multifractal analysis of daily prices of Brent crude oil for the period of 33 years (1987–2020) using the multifractal detrended fuctuation analysis. We discuss the results and limitations of the static multifractal analysis of historical data of crude oil. The crude oil market contains much more complexity in its dynamics that needs to be examined to draw inferences. These are important for socio-economic and political policy formulation at the global level. Thus the temporal multifractal analysis of historical data of crude oil is performed to understand such complexity. Further, the efect of extreme events on the multifractal properties of the crude oil market is also investigated. It is shown that multifractal spectra evolve through diferent shapes with time and the multifractal asymmetry coefcient can be used as an indicator in the detection of extreme events.
V-SUPER VERTEX OUT-MAGIC TOTAL LABELINGS OF DIGRAPHS
Devi, Guruvaiah Durga,Durga, Morekondan Subhash Raja,Marimuthu, Gurusamy Thevar Korean Mathematical Society 2017 대한수학회논문집 Vol.32 No.2
Let D be a directed graph with p vertices and q arcs. A vertex out-magic total labeling is a bijection f from $V(D){\cup}A(D){\rightarrow}\{1,2,{\ldots},p+q\}$ with the property that for every $v{\in}V(D)$, $f(v)+\sum_{u{\in}O(v)}f((v,u))=k$, for some constant k. Such a labeling is called a V-super vertex out-magic total labeling (V-SVOMT labeling) if $f(V(D))=\{1,2,3,{\ldots},p\}$. A digraph D is called a V-super vertex out-magic total digraph (V-SVOMT digraph) if D admits a V-SVOMT labeling. In this paper, we provide a method to find the most vital nodes in a network by introducing the above labeling and we study the basic properties of such labelings for digraphs. In particular, we completely solve the problem of finding V-SVOMT labeling of generalized de Bruijn digraphs which are used in the interconnection network topologies.
