Effects of dietary inclusion of vitamin C on immune and antioxidant defence system in captive reared juvenile mahseer, Tor putitora (Hamilton, 1822)
No full textThe present trial was conducted to evaluate the effects of dietary L-ascorbyl-2-polyphosphate (vitamin C) on immune and antioxidant defence system in captive-reared juvenile mahseer (Tor putitora (Hamilton, 1822)). The experiment consisted of four treatments (3 replicates each), which received four semi-purified diets containing 0, 100, 200 and 300 mg.kg-1 of vitamin C. A total of 120 fish with an average initial body weight, 2.27 ± 0.01 g were distributed among 12 tanks (10 fish per tank). At the end of the 70-day experiment, all fish of each group were subjected to hypoxia stress for 48 h. Fish fed 300 mg.kg-1 vitamin C showed significantly increased (P < 0.05) serum lysozyme activity in response to hypoxia stress, followed by 200 and 100 mg.kg-1 vitamin C. Similar results were observed for glutathione peroxidase (GSH-Px), glutathione reductase (GSR) and superoxide dismutase (SOD) activity. After hypoxia, malondialdehyde (MDA) concentration was considerably reduced (P < 0.05) in fish fed 300 mg.kg-1 vitamin C. These results indicated that in stressful conditions feeding diets supplemented with 300 mg.kg-1 vitamin C would be better than 200 and 100 mg.kg-1 vitamin C, to obtain the optimum immune and antioxidant status of captive-reared juvenile mahseer.Quaid-i-Azam UniversityDepartment of Animal Sciences Faculty of Biological Sciences Quaid-i-Azam UniversityAquaculture Center São Paulo State University (UNESP), Via de Acesso Prof. Paulo Donato Castellane s/nAquaculture Center São Paulo State University (UNESP), Via de Acesso Prof. Paulo Donato Castellane s/
Effects of dietary selenium nanoparticles on physiological and biochemical aspects of juvenile Tor putitora
No full textA 70-day feeding trial was conducted to evaluate the effects of dietary supplementation of selenium nanoparticles (Se-NPs) on physiological and biochemical aspects of juvenile mahseer (Tor putitora) fish. Maintaining a 40% protein level, 2 different experimental diets supplemented with 0% Se-NPs and 0.68 Se-NPs mg kg(-1) were fed to triplicate groups of fish. The experiment was conducted in a semistatic condition consisting of 6 fiber tanks. The fish were first acclimatized, and then 30 fish per tank were randomly put into each fiber tank. At the end of the feeding trial, samples were collected from the fish and analyzed. Results obtained showed that the diet supplemented with Se-NPs significantly increased (P < 0.05) physiological aspects like red blood cell count, hemoglobin level, hematocrit values, and lysozyme activity as compared to the basal diet. Similarly, biochemical parameters including serum growth hormone levels, tissue total protein content, and glutathione peroxidase activity in liver and muscle tissues of T. putitora also significantly (P < 0.05) increased. Thus, dietary Se-NP supplementation at the rate of 0.68 mg kg(-1) diet has very beneficial effects on the physiobiochemical health aspects of juvenile T. putitora.Fisheries and Aquaculture Laboratory, Department of Animal Sciences, Faculty of Biological Sciences, Quaid-i-Azam University, Islamabad, PakistanQuaid I Azam Univ, Dept Anim Sci, Fisheries & Aquaculture Lab, Islamabad, PakistanQuaid I Azam Univ, Natl Ctr Phys, Islamabad, PakistanSao Paulo State Univ CAUNESP, Ctr Aquaculture, Sao Paulo, BrazilSao Paulo State Univ CAUNESP, Ctr Aquaculture, Sao Paulo, Brazi
Seri Rama and Maharaja Wana in Wayang Kulit Kelantan: Visual Analysis of Their Puppets
No full textWayang Kulit Kelantan, currently one of the two remaining shadow play forms in Malaysia, remains active in the northern part of peninsular Malaysia in particular the state of Kelantan, up till southern part of Thailand. It performs mainly a localized Malay folk version Hikayat Maharaja Wana derived from the famous Indian epic Ramayana, in contrast to the other literary version Hikayat Seri Rama.
The origin of Wayang Kulit Kelantan, although much has been debated, could have possibly derived from the pre-Islamic or archetypal prototype of Wayang Kulit Purwa of Java, following the Majapahit Empire’s collapse and the spread of Islam on that island in the 16th century (Ghulam-Sarwar, 2004, pp. 61-62). The introduction of the legendary nine saints (wali Songo) in Java (Ghulam-Sarwar, 1994, pp. 274-275) led to the migration of this proto shadow play from Java to Bali and other Indonesian islands as well as the Malay Peninsula. Strong influences of animism, Hinduism, traditional Javanese beliefs and Islam are evident in Wayang Kulit Kelantan performances (Ghulam-Sarwar, 1993, pp. 4-5), as well as in the conception of the epic’s characters and their visualization on leather puppets.
Author gender identification for Urdu articles
No full textThis is an accepted manuscript of an article published by Springer in Lecture Notes in Computer Science on 21/09/2022. The accepted version of the publication may differ from the final published versionIn recent years, author gender identification has gained considerable attention in the fields of computational linguistics and artificial intelligence. This task has been extensively investigated for resource-rich languages such as English and Spanish. However, researchers have not paid enough attention to perform this task for Urdu articles. Firstly, I created a new Urdu corpus to perform the author gender identification task. I then extracted two types of features from each article including the most frequent 600 multi-word expressions and the most frequent 300 words. After I completed the corpus creation and features
extraction processes, I performed the features concatenation process. As a result each article was represented in a 900D feature space. Finally, I applied 10 different well-known classifiers to these features to perform the author gender identification task and compared their performances against state-of-the-art pre-trained multilingual language models, such as mBERT, DistilBERT, XLM-RoBERTa and multilingual DeBERTa, as well as Convolutional Neural Networks (CNN). I conducted extensive experimental studies which show that (i) using the most frequent 600 multi-word expressions as features and concatenating them with the most frequent 300 words as features improves the accuracy of the author gender identification task, and (ii) support vector machines outperforms other classifiers, as well as fine-tuned pre-trained language models and CNN. The code base and the corpus can be found at: https://github.com/raheem23/Gender_Identification_Urdu
An overview of the ongoing insights in selenium research and its role in fish nutrition and fish health
No full textIn the present review, the ongoing researches about selenium research in fish nutrition have been comprehensively discussed. Selenium research is getting popularity in fish nutrition as it is required for the normal growth and proper physiological and biochemical functions in fish. Its deficiency or surplus amounts create severe problems in fish. It is available as inorganic form, organic form, and nano form. In fish, most of the previous research is about the selenium requirements for fish by using only one selenium source mainly the inorganic one. Selenium shows maximum biological activity and bioavailability when it is supplied in proper form. However, to differentiate the more bioavailable and less toxic form of selenium, sufficient information is needed about the comparative bioavailability of different selenium forms in different fish species. In fish, important data about the new forms of selenoproteins is still scarce. Therefore, it is necessary to focus on the determination and elucidation of the new selenoproteins in fish through the utilization of recent approaches of molecular biology and proteomics. The adaptation of these new approaches will replace the old fashioned methodologies regarding the selenium research in fish nutrition. Moreover, the use of molecular biology and proteomics-based new approaches in combination with selenium research will help in optimizing the area of fish nutrition and will improve the feed intake, growth performance, and more importantly the flesh quality which has a promising importance in the consumer market.Sao Paulo State Univ, Ctr Aquaculture, Jaboticabal, SP, BrazilQuaid I Azam Univ, Dept Anim Sci, Islamabad, PakistanSao Paulo State Univ, Ctr Aquaculture, Jaboticabal, SP, Brazi
Genotyping-by-sequencing based intra-specific genetic map refines a ‘‘QTL-hotspot” region for drought tolerance in chickpea
No full textTo enhance the marker density in the "QTL-hotspot" region, harboring several QTLs for drought tolerance-related traits identified on linkage group 04 (CaLG04) in chickpea recombinant inbred line (RIL) mapping population ICC 4958 × ICC 1882, a genotyping-by-sequencing approach was adopted. In total, 6.24 Gb data from ICC 4958, 5.65 Gb data from ICC 1882 and 59.03 Gb data from RILs were generated, which identified 828 novel single-nucleotide polymorphisms (SNPs) for genetic mapping. Together with these new markers, a high-density intra-specific genetic map was developed that comprised 1,007 marker loci spanning a distance of 727.29 cM. QTL analysis using the extended genetic map along with precise phenotyping data for 20 traits collected over one to seven seasons identified 49 SNP markers in the "QTL-hotspot" region. These efforts have refined the "QTL-hotspot" region to 14 cM. In total, 164 main-effect QTLs including 24 novel QTLs were identified. In addition, 49 SNPs integrated in the "QTL-hotspot" region were converted into cleaved amplified polymorphic sequence (CAPS) and derived CAPS (dCAPS) markers which can be used in marker-assisted breeding.Deepa Jaganathan, Mahendar Thudi, Sandip Kale, Sarwar Azam, Manish Roorkiwal, Pooran M.

Prevotella intermedia ジペプチダーゼAの基質特異性の決定と新規オートプロセシング機構
No full textPrevotella intermedia, a gram-negative anaerobic rod, is frequently observed in subgingival polymicrobial biofilm from adults with chronic periodontitis. Peptidases in periodontopathic bacteria are considered to function as etiological reagents. Pre. intermedia OMA14 cells abundantly express an unidentified cysteine peptidase specific for Arg-4-methycoumaryl-7- amide (MCA). BAU17746 (locus tag, PIOMA14_I_1238) and BAU18827 (locus tag, PIOMA14_II_0322) emerged as candidates of this peptidase from the substrate specificity and sequence similarity with C69-family Streptococcus gordonii Arg-aminopeptidase. The recombinant form of the former solely exhibited hydrolyzing activity toward Arg-MCA, and BAU17746 possesses a 26.6% amino acid identity with the C69-family Lactobacillus helveticus dipeptidase A. It was found that BAU17746 as well as L. helveticus dipeptidase A was a P1-position Arg-specific dipeptidase A, although the L. helveticus entity, a representative of the C69 family, had been reported to be specific for Leu and Phe. The fulllength form of BAU17746 was intramolecularly processed to a mature form carrying the N-terminus of Cys15. In conclusion, the marked Arg-MCA-hydrolyzing activity in Pre. intermedia was mediated by BAU17746 belonging to the C69-family dipeptidase A, in which the mature form carries an essential cysteine at the N-terminus.長崎大学学位論文 学位記番号:博(医歯薬)甲第1215号 学位授与年月日:令和2年3月19日Author: Mohammad Tanvir Sarwar, Yuko Ohara-Nemoto, Takeshi Kobayakawa, Mariko Naito and Takayuki K.
