Dietary Inclusion of Garlic (Allium Sativum) Extract Enhances Growth and Resistance of Rohu (Labeo Rohita) Against Motile Aeromonas Septicaemia
Authors: Paul SI , Rahman MM , Salam MA , Surovy MZ , Islam T
Published: March 2022

Motile Aeromonas septicaemia (MAS) caused by Aeromonas spp. is one of the major fish diseases that causes substantial losses in the aquaculture industry. The present study was conducted to screen the in vitro inhibitory effects of garlic extracts on Aeromonas veronii isolated from MAS, evaluate the effects of dietary inclusion of garlic extracts on growth and prevention of MAS in Labeo rohita. In vitro antibacterial activities of garlic aqueous and organic solvent extracts (ethyl acetate, methanol, ethanol, and acetone) were screened by disc diffusion assay. The minimum inhibitory concentrations (MICs) of ethyl acetate and methanol extracts were determined by using a quantitative bioassay method. Four groups of fish were fed garlic ethyl acetate extract at the rate of 0 (T1, control), 6.25 (T2), 12.50 (T3), and 25.00 (T4) mg/kg feed with three replications for 90 days. The fish fed with different concentrations of garlic extracts were artificially challenged with the high virulent A. veronii strain B55. In this study, ethyl acetate extract of garlic inhibited all the A. veronii strains (A22, B7, B9, B19, B27, B36, B55, F143, K743, and L1324) with the maximum inhibition zones. The MICs of ethyl acetate and methanol extracts were obtained 31.25 and 62.5 μg/ml, respectively. The final weight gain of L. rohita was obtained 28.21±0.51, 31.33±0.76, 40.05±0.76, and 34.82±0.51 g in the treatments T1, T2, T3, and T4, respectively. The growth of ethyl acetate extracts-fed fish were significantly (p < 0.05) higher compared to the control. The specific growth rate was also found significantly higher in the T3, T4, and T2 relative to control. The fish fed garlic extracts enriched feed at 12.5, and 25 mg/kg developed resistance against MAS, while all the control fish died with expressions of distinct disease symptoms. Therefore, garlic ethyl acetate extracts could be used for growth enhancement and prevention of MAS in L. rohita.

Established Rice Ratoon for Improving Cropping Intensity and Income
Authors: Neogi MG , Miah MAH , Biswas JC , Uddin AKMS , Rashid MM
Published: March 2022

Transplanted aman rice suffers from frequent flash flood damage in northern Bangladesh and thus grain yield decreases. An experiment was conducted at the RDRS Farm, Rangpur, Bangladesh to evaluate production opportunity and income generation from growing ratoon rice in between boro and aman seasons during May to July in fallow land as additional harvests. Ratoon seedlings of ACI-2 boro hybrid rice was transplanted and tested against the performance of conventional transplanted BR11 and BRRI dhan46. BR11 gave higher grain yield and profit than ratoon cropping. However, ratoon crop required only 75-80 days for maturity. Thus, it would be possible to incorporate rice ratoon cropping in fallow lands immediately after harvest of boro rice in April- May as additional crop. After harvests of the ratoon rice, farmers can grow traditional aman varieties as conventional practice. If ratoon of ACI-2 (hereafter ratoon rice)-BRRI dhan46 cropping system is practiced then total grain yield from the system was 8.42 t ha-1, which was almost double than conventional BR11 or BRRI dhan46 cultivation. Total net income of boro and ratoon rice-BRRI dhan46 system was also higher (Tk 55,090 ha-1) compared to traditional BR11 aman rice cultivation (Tk 35,802 ha-1). The overall result indicated that just immediate after boro rice harvests, growing rice from ratoon seedlings of ACI-2 followed by BRRI dhan46 in aman season provided higher net profit than traditional cultivation of BR11. The result also implies that growing rice by using ratoon seedlings can ensure three harvests (boro rice-ratoon rice-aman rice) in the same year instead of growing two traditional rice (boro rice-aman rice) crops in a year with additional net profit of Tk 19,288 ha-1 year-1. Moreover, use of rice ratoon seedlings might help farmers in intensification of crop in flash flood prone areas of the country.

Ascorbic Acid Influences on Growth and Yield of Tomato
Authors: Rahman MA , Zakaria M , Mia MAB , Biswas MS
Published: March 2022

Reactive oxygen species (ROS) generated in various metabolic reactions in plants are mostly known for toxicity. Whereas ascorbic acid (AsA) involves in various physiological and biochemical processes; and acts as a ROS scavenger. Therefore, the experiment was conducted to investigate the effects of exogenous application of AsA on growth and yield of tomato plants. The ROS scavenger AsA was applied in the leaves of tomato plants in four treatment combinations (T1-Control; T2-0.5 mM; T3-2.0 mM and T4-4.0 mM) with three replications. Among the treatments, AsA at 4.0 mM (T4) efficiently increased leaf length (12%), inflorescence length (17%), and flower number (29%) than the untreated control plants. AsA at 0.5 and 2.0 mM also showed positive effects on the plant morphology to a lesser extent. Importantly, AsA at 4.0 mM increased yield by 18% than the control treatment. In physiochemical parameters, AsA at 4.0 mM (T4) was retained 64.07% higher chlorophyll content than the control plant even after 60 days of application. Exogenous application of AsA effectively reduced oxidative stress of the plant, which was attributed to the less accumulation of H2O2 and lipid peroxidation of membrane lipids. AsA at 4.0 mM decreased H2O2 and MDA accumulation by 39% and 45%, respectively, compared with the control plants. Therefore, exogenous application of AsA is a useful tool to enhance growth and yield of tomato under field conditions by lowering the accumulation of ROS and lipid peroxidation.

To study the growth and flowering of gladiolus by using different chemicals and PGR, an experiment was conducted at the research field of the Department of Horticulture, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur from September 2019 to May 2020. Medium sized (3.5-4.5 cm) corms of the variety BARI gladiolus-3 were planted at about 6-9 cm depth in a unit plot of 1.8 m X 1.2 m maintaining a spacing of 30 cm X 20 cm following Randomized Complete Block Design (RCBD) with 3 replications. Foliar spray with 3 levels of GA3 (150, 200 and 250 ppm), 2 levels of KNO3 (1 and 2%) and 2 levels of Ca(NO3)2 (1 and 2%) along with control (only tap water) was done at 30, 45 and 60 days after planting (DAP). Results revealed that although, the tallest plant (62.9 cm) was observed in T3; where, GA3 was applied at the highest concentration (250 ppm) but it was statistically at par with the height recorded in T2 (60.7 cm) and T4 (59.4 cm); where, GA3 was applied @ 200 ppm and KNO3 was applied @ 1%, respectively. Although, Spike length in T3 (85.7 cm) varied statistically with T2 (75.9 cm) but rachis length in T3 (57.4 cm) was statistically similar with T2 (56.8 cm). Floret length and breadth in T2 (11.3 cm and 11.3 cm, respectively) were higher than T3 (10.7 cm and 10.8 cm, respectively). Number of floret per spike was statistically similar in all treatments except T4 (12.7) and T7 (12.4). The highest leaf area was recorded in T5 (189.5 cm2); where, KNO3 was applied @ 2% and this was statistically similar to all other treatments except T6 (148.9 cm2); where Ca(NO3)2 was applied @ 1%. On overall consideration, gibberellic acid (GA3) @ 250 ppm may be used for better growth and flowering of gladiolus.

Published: March 2022

Experiment was conducted to determine the changes of jute seed qualities under ambient storage condition over one year period. Jute seed produced from three genotypes (O-72, O-3820 and Acc.4311) sown on three dates (31 July, 15 August and 30 August) over four locations (Manikganj, Cumilla, Dinajpur and Jashore) and preserved in plastic containers at ambient condition. Seed qualities were assessed in the laboratory for every six months of storage. Results showed that fresh jute seed maintained 94 to 98% germination which declined with the advent of storage period. Irrespective of genotype, sowing date and location, germination capacity of jute seed remained more than 80% up to 6 months of storage at ambient condition. Afterwards, seed harvested from genotype Acc.4311 sown on 15 August at Manikganj maintained the highest germination (86%) after 12 months of storage. Seedling dry weight of all the genotypes also decreased over the storage period. However, rate of reduction of seedling dry weight was lower in seed harvested from the crop sown on 15 August which indicates that seed obtained from this time can maintain better seedling dry weight even after 12 months of storage. Contrary, electrical conductivity of seed electrolytes increased with the increase of storage period although it was the lowest (285 μ Scm-1) in seed of genotype Acc.4311 harvested from 15 August sowing at Manikganj. Considering different qualities of stored jute seed, the genotype Acc.4311 supposed to be promising for producing good quality seed sown on mid-August at Manikganj environment.

Two emaciated male northern elephant seal (NES) Mirounga angustirostris pups were admitted to The Marine Mammal Center (Sausalito, California, USA) and treated for malnutrition. Complete blood counts showed a progressive moderate to marked leukocytosis characterized by a predominance of large monomorphic mononuclear cells of probable lymphoid origin, frequently with flower-shaped nuclei. Both seals were euthanized due to suspected lymphoid neoplasia. At necropsy, most lymph nodes in both pups were markedly enlarged, some with distinct white nodules, the spleens were diffusely enlarged, and the intestinal mucosae were thickened. Histopathologic features consistent with disseminated large cell lymphoma were identified to varying degrees of severity in lymph nodes, bone marrow, liver, tonsils, spleen, liver, intestines, kidneys, lower urinary tract, and several other organs. Immunohistochemical staining of neoplastic cells was most consistent with B lymphocyte origin, with most cells staining positively for Pax 5 and CD20 with admixed small CD3-positive T lymphocytes and CD204-positive macrophages. PCR and sequencing identified a novel gammaherpesvirus, herein called miroungine gammaherpesvirus 3, from affected tissues. This virus is in a clade outside of named genera that utilize hosts in the suborder Caniformia. The present study is the first description of diffuse large B cell lymphoma with leukemic manifestation and concomitant detection of a novel gammaherpesvirus in free-living NESs. Further research regarding the prevalence of this new gammaherpesvirus and its associated pathogenesis in this species is indicated.

AIM: to improve the results of chronic anal fissure treatment.PATIENTS AND METHODS: the prospective randomized study included 176 patients divided in two groups. Eighty-eight patients underwent fissure excision in combination with injection of botulinum toxin type A (incobotulinum toxin) into the internal anal sphincter (main group, BTA), and 88 patients underwent anal fissure excision in combination with lateral subcutaneous sphincterotomy (control group, LIS).RESULTS: on the 30th day after surgery, spasm of internal anal sphincter, according to profilometry, persisted in 14.8% of patients of the main group (BTA) and 22.7% of patients in the control group (LSS) (p = 0.18), and on the 60th day in 20.4% and 14.8% of patients, respectively (p = 0.32). On the 60th day after surgery, the postoperative wound did not epithelialize in 14% of patients in the BTA group and 1% of the LSS group (p = 0.0006). On the 30th day after surgery, complaints of incontinence were noted by 32% of patients in the BTA group and 31% in the LSS group (p = 0.87), on the 60th day — 7% and 11% of patients, respectively (p = 0.29). The intensity of pain after surgery in the compared groups did not differ both after defecation and during the day (p > 0.05). Expansion of the surgery volume increases the chance of developing temporary anal sphincter incontinence (ASI) by 2.44 times on the 30th day of observation (p = 0.01) and by 3 times — on day 60 (p = 0.04). The use of BTA as a method of internal anal sphincter relaxation increases the chance of slowing down the epithelization of the postoperative wound by 13.7 times [p = 0.01], and the expansion of the surgery volume — by 3.47 times [p = 0.03].CONCLUSION: the use 40 U of botulinum toxin type A after anal fissure excision is not inferior to lateral subcutaneous sphincterotomy in elimination of spasm internal anal sphincter with a comparable incidence of temporary anal sphincter incontinence within 2 months after surgery. Neurotoxin serves as an alternative to sphincterotomy, however, in some cases, it requires the addition of a agent containing human recombinant epidermal growth factor to the postoperative management of patients.

Salmonella is a significant food safety concern in commercial beef production, and some contamination is thought to occur by inclusion of Salmonella-infected peripheral lymph nodes (LN) in ground beef and through fecal contamination. Surveillance in processing plants assists packers in risk management of Salmonella by understanding seasonal trends and risks associated with different cattle types. Approximately 25 fecal samples and 20 LN were collected from animals representing each of five cattle types (cull beef cattle, cull dairy cows, conventional feedlot cattle, all-natural feedlot cattle raised without pharmaceuticals, and grass-finished cattle) and each of five climate regions (mixed-temperatures and dry, mixed-temperatures and humid, hot and humid, hot and dry, cold) during each of three seasons (summer, fall, winter) to better characterize Salmonella inputs into a commercial cattle processing facility. In total, 1,840 fecal samples and 1,550 LN samples were collected. Fecal samples and LN were cultured for Salmonella, and select isolates were serogrouped and screened for antimicrobial resistance. Conventional feedlot cattle had the highest LN Salmonella concentrations (1.17 log10 CFU/g LN) in this data set, while cull dairy cows had the highest fecal Salmonella concentrations (1.96 log10 CFU/g feces). Conventional feedlot cattle and cull dairy cows had the greatest Salmonella prevalence in both LN (32 and 18%, respectively) and feces (37 and 49%, respectively), while all-natural feedlot cattle had the lowest prevalence in the LN (3%) and feces (7%). As expected, Salmonella prevalence and concentration was lowest for all cattle types during winter compared to warmer seasons. When examined by climate region, a greater Salmonella prevalence in both feces and LN was observed in climate region 4 (hot-dry), than the other regions. Only 21 of 50 Salmonella isolates examined for antimicrobial susceptibility were identified as multidrug resistant (MDR); cull dairy cows were responsible for 48% of MDR isolates, cull beef cattle were responsible for 38%, and conventional feedlot, grass-fed, and all-natural feedlot cattle were each responsible for 4.8%. These results indicate that different production schemes, season, and climate region may influence which cattle are most likely to introduce Salmonella to the abattoir, allowing for greater risk awareness during the slaughter process.

Published: March 2022

Subtype classification is critical in the treatment of gliomas because different subtypes lead to different treatment options and postoperative care. Although many radiological- or histological-based glioma classification algorithms have been developed, most of them focus on single-modality data. In this paper, we propose an innovative two-stage model to classify gliomas into three subtypes (i.e., glioblastoma, oligodendroglioma, and astrocytoma) based on radiology and histology data. In the first stage, our model classifies each image as having glioblastoma or not. Based on the obtained non-glioblastoma images, the second stage aims to accurately distinguish astrocytoma and oligodendroglioma. The radiological images and histological images pass through the two-stage design with 3D and 2D models, respectively. Then, an ensemble classification network is designed to automatically integrate the features of the two modalities. We have verified our method by participating in the MICCAI 2020 CPM-RadPath Challenge and won 1st place. Our proposed model achieves high performance on the validation set with a balanced accuracy of 0.889, Cohen’s Kappa of 0.903, and an F1-score of 0.943. Our model could advance multimodal-based glioma research and provide assistance to pathologists and neurologists in diagnosing glioma subtypes. The code has been publicly available online at https://github.com/Xiyue-Wang/1st-in-MICCAI2020-CPM.

Spinocerebellar ataxia type 3 (SCA3) is a dominantly inherited cerebellar ataxia caused by the expansion of a polyglutamine (polyQ) repeat in the gene encoding ATXN3. The polyQ expansion induces protein inclusion formation in the neurons of patients and results in neuronal degeneration in the cerebellum and other brain regions. We used adeno-associated virus (AAV) technology to develop a new mouse model of SCA3 that recapitulates several features of the human disease, including locomotor defects, cerebellar-specific neuronal loss, polyQ-expanded ATXN3 inclusions, and TDP-43 pathology. We also found that neurofilament light is elevated in the cerebrospinal fluid (CSF) of the SCA3 animals, and the expanded polyQ-ATXN3 protein can be detected in the plasma. Interestingly, the levels of polyQ-ATXN3 in plasma correlated with measures of cerebellar degeneration and locomotor deficits in 6-month-old SCA3 mice, supporting the hypothesis that this factor could act as a biomarker for SCA3.

Published: March 2022

Enzyme catalysis, made tremendous progress over the last years in identification of new enzymes and new enzymatic reactivity’s as well as optimization of existing enzymes. However, the performance of the resulting processes is often still limited, e.g., in regard of productivity, realized product concentrations and the stability of the enzymes. Different topics (like limited specific activity, unfavourable kinetics or limited enzyme stability) can be addressed via enzyme engineering. On the other hand, there is also a long list of topics that are not addressable by enzyme engineering. Here typical examples are unfavourable reaction thermodynamics, selectivity in multistep reactions or low water solubility. These challenges can only be addressed through an adaption of the reaction system. The procedures of process intensification (PI) represent a good approach to reach most suitable systems. The general objective of PI is to achieve significant benefits in terms of capital and operating costs as well as product quality, waste, and process safety by applying innovative principles. The aim of the review is to show the current capabilities and future potentials of PI in enzyme catalysis focused on enzymes of the class of oxidoreductases. The focus of the paper is on alternative methods of energy input, innovative reactor concepts and reaction media with improved properties.

To study the relationship between matrix suction and conductivity in unsaturated granite residual soil and realize the matrix suction prediction of soil slope based on conductivity, laboratory and field tests are carried out on undisturbed soil at different depths of the Yandou village landslide in Sanming City, Fujian Province, China. Through physical and chemical property analysis, soil-water characteristic curves and electric parameter matrix suction prediction models for unsaturated granite residual soil at different depths of the target area are obtained. Based on the proposed model, the matrix suction distribution of on-site soil slope is predicted and the dynamic response law under the influence of artificial rainfall is studied. The results show that: (1) The transverse conductivity, average structure factor, average shape factor, and anisotropy coefficient of unsaturated soil are related to the soil saturation degree. By considering the above parameters, the comprehensive structure parameter Re is introduced and its functional relationship with matrix suction is established. (2) Under artificial simulated rainfall, the saturation, hysteresis of the conductivity parameters, and matrix suction response of the slope occurs, which is controlled by soil depth, permeability and rainfall intensity. The matrix suction is distributed in layers on the profile and its recovery rate is slower than saturation. The suction contour map shows a parabola shape with the opening downward. (3) The relationship between the conductivity parameters of the residual soil slope and matrix suction is further revealed and a new method to indirectly measure matrix suction is proposed. Its feasibility is verified based on field tests, which is of great significance to landslide monitoring and early warning.

Published: March 2022

It is challenging to deal with the optimal scheduling problem of the multi-regional integrated energy system (MIES) precisely and efficiently due to its multi-dimensional nonlinear characteristics. This article proposes an iterative linearization approach to solve the complicated and nonlinear MIES optimization problem with a well-balanced trade-off between accuracy and computation efficiency. In particular, the proposed approach is a combination of the modified piecewise linearization (PWL) tactic and the sequential linear programming (SLP) algorithm. The modified PWL method is developed to improve the speed-accuracy trade-off of the linearization, while the SLP algorithm is used to linearize the multi-dimensional nonlinear functions and narrow the approximation error iteratively. In this way, accurate but highly nonlinear formulations such as heat network models in the variable flow and variable temperature (VF-VT) mode can be considered in the optimization and solved efficiently. Finally, the effectiveness of the given approach is validated in a day-ahead optimal scheduling case of a four-region MIES.
