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

<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>
Synthesis of Cu-Cu2S Hybrid Microplates and Their Photocatalytic Application

Copper (Cu) and copper-based nano/microparticles have recently triggered much research interest for the development of low-cost and high-performance catalysts that have industrial applications. However, oxidation of Cu to CuO is a commonly observed phenomenon when the sample is handled under ambient conditions. In this work, we reported an aqueous-phase synthesis of hybrid metal–semiconductor Cu-Cu₂S microparticles by using Cu microplates templates in a rapid surface sulfidation process while preventing the quick oxidation of Cu monometallic microparticles. The morphology and structure of hybrid Cu-Cu₂S were characterized by scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. The presence of metal and semiconductor in these hybrid structures contributes to improve the photocatalytic properties due to the synergistic effects between the two components.

The estimation of radioactivity level is vital for population health risk assessment and geological point of view and can be evaluated as rate of exhalation and source concentration (<sup>226</sup>Ra, <sup>232</sup>Th and <sup>40</sup>K). The present study deals with the soil samples for investigation of radionuclides content and exhalation rates of radon -thoron gas from different sites in northern Haryana, India. Absorbed dose and associated index estimated in the present study are the measures of environmental radioactivity to inhalation dose. Effective doses received by different tissues and organs by considering different occupancy and conditions are also measured. Exhalation rates of radon and thoron are measured with active scintillation monitors based on alpha spectroscopy namely scintillation radon (SRM) and thoron (STM) monitors respectively. Sample height was optimized before measurement of thoron exhalation rate using STM. Average values of radon and thoron exhalation are found 16.6 ± 0.7 mBqkg<sup>-1</sup>h<sup>-1</sup> and 132.1 ± 2.6 mBqm<sup>-2</sup>s<sup>-1</sup> respectively. Also, a simple approach was also adopted, to evaluate the thoron exhalation which accomplished a lot of challenges, the results are compared with the data obtained experimentally. The study is useful in the nationwide mapping of radon and thoron exhalation rates for understanding the environmental radioactivity status.

<P>In plants heme containing cytochrome P450 (P450) is a superfamily of monooxygenases that catalyze the addition of one oxygen atom from O2 into a substrate, with a substantial reduction of the other atom to water. The function of P450 families is attributed to chemical defense mechanism under terrestrial environmental conditions; several are involved in secondary and hormone metabolism. However, the evolutionary relationships of P450 genes in Panax ginseng remain largely unknown. In the present study, data mining methods were implemented and 116 novel putative P450 genes were identified from Expressed Sequence Tags (ESTs) of a ginseng database. These genes were classified into four clans and 22 families by sequence similarity conducted at amino acid level. The representative putative P450 sequences of P. ginseng and known P450 family from other plants were used to construct a phylogenetic tree. By comparing with other genomes, we found that most of the P450 genes from P. ginseng can be found in other dicot species. Depending on P450 family functions, seven P450 genes were selected, and for that organ specific expression, abiotic, and biotic studies were performed by quantitative reverse transcriptase-polymerase chain reaction. Different genes were found to be expressed differently in different organs. Biotic stress and abiotic stress transcript level was regulated diversely, and upregulation of P450 genes indicated the involvement of certain genes under stress conditions. The upregulation of the P450 genes under methyl jasmonate and fungal stress justifies the involvement of specific genes in secondary metabolite biosynthesis. Our results provide a foundation for further elucidating the actual function and role of P450 involved in various biochemical pathways in P. ginseng.</P>
