Abstract
Ornamental fish is one of Indonesia’s export commodities with destination countries dominated by Japan, Singapore, America, China, England, Korea, and Malaysia. This paper aims to provide an overview of the potential development, problems, and challenges of ornamental fish farming in Depok City. The research was conducted in August 2020 in Bojongsari District, Depok City, West Java Province. Data collected in the form of primary data and secondary data. The survey method was used in this research, with interview techniques using a questionnaire, in-depth interviews, and focus group discussion to stakeholders. Data analysis used simple statistical analysis and qualitative descriptive. The results showed that Depok City is one of the areas with the third-largest potential for ornamental fish in Indonesia, with its center in Bojongsari District. There are two types of ornamental fish farming in Bojongsari, namely hatchery, and nursery of ornamental fish. The dominant types of ornamental fish commodities are neon tetra, cardinal, and red nose. The problems in the development of ornamental fish farming include; a) technical problems, namely limited land; availability and quality of broodstock; limited fish seeds; quantity and quality of water (decrease in water quality); disease b) socio-cultural problems, namely the limited number of fish breeders; difficulty accepting new technology; marketing still depends on demand; access to price information at the exporter level; the workforce still comes from within the family and depends on the business owner; Human resources related to farming techniques; and financial management. So that it takes solutions related to problems and challenges through government policies in fostering and mentoring business actors, both technology assistance, as well as business management and socio-cultural behavior.

Abstract
This study was conducted to analyze the millennial consumer behavior (MCB), purchase intention (PI) and purchase decision (PD) on fisheries-based functional foods (F3) in the form of fish oil, spirulina, processed fish food, and others through e-commers Tokopedia. Data were collected from 144 millennials consumer in Java Island who have known or bought F3 through Tokopedia. Structural Equation Modeling (SEM) was used to test the effect of purchase attitude (PA), subjective norm (SN), perceived behavioral control (PBC) on PI and PD. The empirical results show that there is a positive and significant relationship of PA, SN, PBC on PI. Also, PBC and PI to PD. Theory of Planned Behavior (TPB) has been proven to effectively explain the MCB on purchasing F3 at Tokopedia, the explanatory power is 57.5% for PI and 9% for PD. The most effective effect on PI come from SN, with total effect 35.4%, while PD mostly determined by PBC through PI. Tokopedia and F3 vendors need to pay more attention and adjustment of marketing strategy to increase PI and PD of MCB on purchasing F3.
Phytochemical analysis and antimicrobial activities of mangrove plant (Rhizophora apiculata) against selected fish pathogenic bacteria
Authors: Laith A A 
Published: April 2021

Abstract

Rhizophora apiculata leaf extracts were tested on the isolated growth of S. agalactiae and E. coli and extraction of the bioactive compounds were performed using Soxhlet extraction technique with methanol (MtOH) as the organic solvent. The presence of various phytochemicals in bioactive constituents of the plant was detected using standard chemical procedures. The Kirby-Bauer test was used for the antibacterial assay, and an in vitro assay was conducted for minimum inhibitory concentration (MIC) and minimum bacterial concentration (MBC). Brine shrimp lethality assay evaluated the toxicity of R. apiculata. Antibiotic susceptibility test showed high rates of E. coli resistance to neomycin and sensitivity to tetracycline and amoxycilin, while S. agalactiae showed sensitivity to all antibiotics. Inhibition zones of R. apiculata leave extract against the microorganisms recorded in the range of 2-9 mm. Increasing the inhibition zone is dependent on increasing plant extract concentrations. The (MIC) testing range of R. apiculata was 6.25 mg/ml to 12.5 mg/ml against S. agalactiae and E. coli, respectively. The MBC/MIC ratio of S. agalactiae demonstrated to be bactericidal, and the MBC/MIC ratio of E. coli was bacteriostatic. R. apiculata recorded an LC50 value of 81 mg/ml. The findings of this study reveal the valuable metabolites found in mangrove leaves. The most important secondary metabolites are alkaloids, terpenoids and tannins as well as saponins and steroids, but not flavonoids. This study suggests that Rhizophora apiculata has the potential to be a valuable candidate in the discovery of antimicrobial compounds against fish pathogens.

Published: April 2021

Abstract
Textile dyes are a combination of organic compounds, chromophores, and auxochromes as activators of chromophore work and binders between colors and fibers. In the industry, a large amount of waste of textile dye is produced daily. Before discharge into the environment, the waste must be processed so does it contain less amount of dyes. Removal of textile dye can be carried out using an adsorption process, one of which uses adsorbents derived from chitin and chitosan. This study aims to provide an overview of the impact of different concentrations of acid solutions used in the manufacture of adsorbents from shrimp waste and their capacity as textile dye adsorbents. The method used in this study is the article review method by comparing the results of the published articles. The gathered result showed that several dyes could be eliminated using chitin and chitosan, such as rhodamine B, methylene orange, methylene blue, direct black 38, procion red, methylene violet, reactive red, direct blue 78, indigo carmine dye. This overview might provide a platform to prepare better chitin-based adsorbent to eliminate dyes used in the industry

Published: April 2021

Abstract
Catfish (Pangasius pangasius) is one of popular freshwater fisheries commodities and its growth relatively fast. Fish growth and survival were affected by feed. The high-quality feed is expensive so it can be added with alternative feed ingredients such as Seligi leaf flour. Seligi leaf flour has 11.53% protein and 15.48% crude fibre. However, high crude fiber can be overcome by fermentation using probiotics. This study aims to determine the use of Seligi leaf flour fermentation (Phyllanthus buxifolius) in feed on fat retention and energy retention of catfish (Pangasius pangasius). This study used an experimental method with a completely randomized design (CRD) consisting of four treatments (0%, 2%, 4%, and 6%) with five replications. Data analysis used Analysis of Variance (ANOVA) and continued with Duncan’s Multiple Range Test. The results of the research that had been carried out were significant differences (P <0.05) on fat retention and energy retention of catfish. The highest fat retention and energy retention was in P2 treatment, while the lowest fat retention and energy retention was in P0 treatment.
Structures and functions of carbohydrate-active enzymes of chitinolytic bacteria Paenibacillus sp. str. FPU-7
Authors: Itoh Takafumi 
Published: April 2021

ABSTRACT
Chitin and its derivatives have valuable potential applications in various fields that include medicine, agriculture, and food industries. Paenibacillus sp. str. FPU-7 is one of the most potent chitin-degrading bacteria identified. This review introduces the chitin degradation system of P. str. FPU-7. In addition to extracellular chitinases, P. str. FPU-7 uses a unique multimodular chitinase (ChiW) to hydrolyze chitin to oligosaccharides on the cell surface. Chitin oligosaccharides are converted to N-acetyl-d-glucosamine by β-N-acetylhexosaminidase (PsNagA) in the cytosol. The functions and structures of ChiW and PsNagA are also summarized. The genome sequence of P. str. FPU-7 provides opportunities to acquire novel enzymes. Genome mining has identified a novel alginate lyase, PsAly. The functions and structure of PsAly are reviewed. These findings will inform further improvement of the sustainable conversion of polysaccharides to functional materials.

Abstract
The Kisspeptin/Kiss1r system is a key regulator of reproduction by stimulating gonadotrophin-releasing hormone and luteinizing hormone release, and in vitro studies have shown that Kisspeptin can modulate angiogenesis and immune function, factors that are also essential for reproduction However, there are no studies on the expression of Kisspeptin/Kiss1r at the maternal-fetal interface in domestic cats and its relationship with angiogenic and immunological mediators. Thus, our objective was to evaluate the spatiotemporal expression profile of Kisspeptin/Kiss1r and angiogenic and immunological mediators in the uterus and placenta of domestic cats during pregnancy. Uterus and placenta samples were collected from cats in mid pregnancy (N = 6) and late pregnancy (N = 6), in addition to uterus from non-pregnant cats in diestrus (N = 7), to evaluate protein and gene expression of kisspeptin (Kiss1), kisspeptin receptor (Kiss1r), vascular endothelial growth factor (VEGF), tyrosine kinase receptor (Flk-1), placental growth factor (PLGF), interferon gamma (INFγ), migration inhibiting factor (MIF), tumor necrosis factor (TNFα), interleukins (IL6 and IL10) by immunohistochemistry and quantitative polymerase chain reaction. Pregnancy increased the uterine expression of Kiss1 and Kiss1r, especially at the late pregnancy, in addition to upregulating INFy, MIF, Vegf, Il10, and Tnf and downregulating Plgf. Higher placental expression of Kiss1r and Plgf mRNA occurred at the late pregnancy, while the expression of Kiss1, VEGF, Flk-1, INFy, TNFα, Il6, and IL10 was higher in the mid of pregnancy. A positive correlation between Kiss1 and Tnf was observed in the placenta, while Kiss1r had a negative correlation with Infγ, Il6, and Il10. The findings reveal that Kisspeptin/Kiss1r and angiogenic and immunological mediators at the maternal-fetal interface of pregnant cat have a gene correlation and are modulated by the gestational age. These data suggest possible functional links of Kisspeptin in placental angiogenesis and immunology.
Telenutrition for Inflammatory Bowel Disease: A Tipping Point for Dietary Wellness
Authors: Elamin Sami , Cohen Jonah 
Published: April 2021

Abstract
Inflammatory bowel disease (IBD), Crohn’s disease and ulcerative colitis, cause inflammation of the digestive tract. It is estimated that about three million Americans and, globally, over six million individuals, suffer from IBD. While most physicians, especially gastroenterologists, are experts in the function and pathology of the gastrointestinal tract, factors such as nutrition science education and training, bandwidth, culture, language, and the longitudinal nature of dietary care, represent some of the barriers to receiving optimal nutritional guidance. Remote dietary expert counseling, an emerging solution that has been further highlighted by the COVID-19 pandemic, can improve IBD patients’ nutritional status, avoid food triggers, and reduce the frequency and severity of exacerbations.
Mi china juventud: Childhood and Hybrid acts in Cuéntame cómo pasó
Authors: May Delphi Pearl 
Published: March 2021

Abstract
Since 1990, Spain has taken in over 200,000 Chinese immigrants. With these citizens often the targets of racist attacks and stereotypes, several filmic and televisual texts offer stereotypical representations of Chinese immigrants either as violent or as a model minority. Nevertheless, texts are emerging that offer more nuanced representations of this migrant body and construct complex characters whose identity struggles form part of Spain’s socio-cultural fabric. Cuéntame cómo pasó (La1, 2001 – present) is one of the first Spanish television programmes to represent a Spanish-Chinese immigrant child this way. This article analyses the Spanish-Chinese immigrant child’s construction within public service broadcasting, arguing that her character’s representation is informed by the channel’s public service responsibility. The analysis considers the notion that her character is the generator of ‘hybrid acts’ and is an agent of cross-cultural contact in her friendship group.

Abstract

OBJECTIVES
Tracheobronchomalacia (TBM) is characterized by collapse of trachea, bronchi or both, leading to dyspnoea, expiratory stridor, coughing or recurrent airway infections. Surgical treatment with aortopexy is warranted for severe TBM. We describe a modified aortopexy technique with aortic wall strap sutures that evenly distributes the traction force over the full width of the aortic arch. The aim of this study was to determine the outcomes of this modified anterior aortopexy technique.

METHODS
Retrospective chart review of all patients undergoing aortopexy with aortic wall strap sutures for TBM between January 2010 and June 2020 in 2 tertiary hospitals in the Netherlands.

RESULTS
Twenty-four patients [median age 9 months (interquartile range 2–117 months); 71% male] underwent aortopexy with the modified technique for TBM (52%), tracheomalacia (40%) or bonchomalacia (8%). Aortopexy was successful in 91.7%, defined as relief or decrease of respiratory symptoms and no need for respiratory support. Complications occurred in 8.3% and mortality was 4%.

CONCLUSIONS
Aortopexy with non-absorbable strap sutures seems an effective and safe treatment for severe TBM. This study supports the hypothesis that strap sutures provide a solid and reliable traction force, but future comparative studies should confirm the benefit of strap sutures over conventional techniques.

Abstract

OBJECTIVES
We sought to explore the efficacy of the endovascular repair of an ascending aortic aneurysm with aortic and mitral regurgitation by 2 novel valved stents.

METHODS
We established models of ascending aortic aneurysms combined with aortic and mitral regurgitation in 10 pig hearts, then implanted self-expanding aortic fenestrated and mitral valved stents via the transapical approach. We applied a fluoroscopy-guided in vitro setting to test the approach, then analysed continuous circulating flushing at 37°C. Finally, we determined operating times, echocardiography and changes of coronary flow as well as fenestration alignment with the coronary ostia.

RESULTS
This approach resulted in a 100% overall technical success rate, excellent handling properties and precise positioning. The time taken to implant the 2 valved stents was 59 ± 12 min. Flow of the left and right coronary arteries did not significantly decrease after the stents were implanted (330.4 ± 12.06 ml/min vs 289.4 ± 5.29 ml/min, P &lt; 0.001; 376.8 ± 10.5 ml/min vs 350.0 ± 14.5 ml/min; P &lt; 0.001). We found no obvious regurgitation and perivalvular leakage; nor did the gradients of the aortic and mitral valves as well as of the left ventricular outflow tract increase significantly. The final angiographic examination and profile of the coronary opening confirmed the good position of the valved stents, the exclusion of the aneurysm and the patency of both coronary arteries.

CONCLUSIONS
These findings indicate the potential for combined transcatheter aortic root and mitral valve replacement in treating aortic root pathologies. In future, in vivo studies are expected to validate this approach and ascertain its durability.

Abstract

OBJECTIVES
To determine the incidence of bioprosthetic structural valve deterioration in dialysis patients undergoing aortic valve replacement compared to that in patients without dialysis.

METHODS
This single-centre retrospective observational study included 1159 patients who underwent aortic valve replacement using bioprosthetic valves for aortic stenosis and/or regurgitation at our institution between 2007 and 2017 [patients with dialysis (group D, n = 134, 12%) or without dialysis (group N, n = 1025, 88%)]. To adjust for potential differences between groups in terms of initial preoperative characteristics or selection bias, a propensity score analysis was conducted. The final sample that was used in the comparison included 258 patients, as follows: 129 patients with dialysis (group D) and 129 patients without dialysis (group N). The cumulative incidences of all-cause death, cardiac death and moderate or severe structural valve deterioration were estimated using the Kaplan–Meier method.

RESULTS
Operative mortality was significantly higher in group D than group N (9% vs 0%, P = 0.001). Kaplan–Meier analysis revealed that in group D, the incidence was significantly higher for all-cause death (P &lt; 0.001, 50% vs 18% at 5 years), cardiac death (P = 0.001, 18% vs 5% at 5 years) and moderate or severe structural valve deterioration (P &lt; 0.001, 29% vs 5% at 5 years) compared with group N.

CONCLUSIONS
The incidence of structural valve deterioration in dialysis patients undergoing aortic valve replacement was higher than that in patients without dialysis. Bioprosthetic valves should be carefully selected in dialysis patients undergoing aortic valve replacement.
Quadratic Hecke Sums and Mass Equidistribution
Authors: Nelson Paul D 
Published: March 2021

AbstractWe consider the analogue of the quantum unique ergodicity conjecture for holomorphic Hecke eigenforms on compact arithmetic hyperbolic surfaces. We show that this conjecture follows from nontrivial bounds for Hecke eigenvalues summed over quadratic progressions. Our reduction provides an analogue for the compact case of a criterion established by Luo–Sarnak for the case of the non-compact modular surface. The novelty is that known proofs of such criteria have depended crucially upon Fourier expansions, which are not available in the compact case. Unconditionally, we establish a twisted variant of the Holowinsky–Soundararajan theorem involving restrictions of normalized Hilbert modular forms arising via base change.
Talking about Death, Becoming Buddhist Families: A Case Study of Religious Parenting Education in Contemporary Taiwan
Authors: Heller Natasha 
Published: March 2021

AbstractReligious belief and practice affect how parents engage their children; the experience of parenting, in turn, can reshape religious ideas. Religious parenting resources serve to guide parents’ understanding of their relationship with their children and provide an important perspective on the family as a site of religious practice. Taking a special issue of a Taiwanese Buddhist journal as a case study to examine parenting strategies around the topic of death, I argue that conversations with their children about death provide parents an opportunity to re-write traditional scripts around death. Discussions around death also serve to re-orient the parent-child relationship to give greater weight to the child’s voice, and offer space for the parent to learn as well. These religious parenting materials provide new Buddhist perspectives on death and on how parents and children should relate.
