Microbial functional diversity and redundancy: moving forward
Authors: Ramond Pierre , Galand Pierre , Logares Ramiro
Published: July 2024

Microbial functional ecology is expanding as we can now measure the traits of wild microbes that affect ecosystem functioning. Here, we review techniques and advances that could be the bedrock for a unified framework to study microbial functions. We then explore the technical, ecological, and evolutionary processes that could explain environmental patterns of microbial functional diversity and redundancy. Next, we suggest reconciling microbiology with biodiversity-ecosystem-functioning studies by testing the significance of microbial functional diversity and redundancy for the efficiency, resistance, and resilience of ecosystem processes. A better understanding of how microbiomes affect ecosystems is crucial to predicting their functioning in a changing planet.

Quiasma óptico: El lugar de las imágenes.
Authors: Bucari Agustín
Published: July 2024

El Artículo plantea los usos de las imágenes técnicas por parte de artistas, tanto en su dimensión pedagógica como en su rol ante la producción visual dentro de sus archivos. La circulación de las imágenes desde la cultura impresa, tanto libros como revistas, postales y otros tipos de materialidades gráficas, tienen una presencia sustancial en los ámbitos de producción de los artistas modernos. Por supuesto que no nos referimos por caso único al collage, sino, el lugar de las imágenes y sus modelos, en particular aquellas que se replican en el ámbito expandido de la cultura y las nuevas estéticas modernas –biocentrismo, estética del ingeniero, Gesamtkunstwerk, Gestalt- sobre la conquista del misterio de la naturaleza (visible-invisible, interno-externo), como son las nuevas técnicas de visualización moderna (microscopio electrónico, rayos X, entre otros) y reproducción de imágenes (fotografía, fotograbado, etc.)
Frente a ello se presentan dos casos de artistas Latinoamericanos, en los cuales las imágenes técnicas son puentes para converger prácticas artísticas y científicas, en proyectos integradores entre Arte, Vida y Espíritu. Para ello el artículo se centrará en el análisis de las prácticas de montaje de los artistas Xul Solar y Juan Batlle Planas, y de forma satelital de algunas de sus obras. Con el objetivo de contraponer sus formas de pensamiento visual no discursivo, las procedencias de sus fuentes, la continuidad en las temáticas seleccionadas en algunos de los libros de sus bibliotecas personales, documentos y escritos, y así, finalmente, dar hipótesis generales de la matriz de dicho pensamiento en sus obras plásticas sentando las bases para un futuro análisis iconológico crítico comparado.

Summary. The objectives of the study are to perform a bibliometric analysis of scientific works of Russian authors on the organization of provision, delivery and training in first aid (FP), published in Russian over the past 20 years. Material and research methods. In September 2023, a search was made in the electronic library eLIBRARY.RU for publications of the type “journal articles” under the heading 76.00.00 “Medicine and Healthcare” containing the term “first aid” in the title, abstract or keywords (search query: ” first* help*”) and published in January 2003 – August 2023. In the process of screening the search results, Russian-language publications were selected that touched on the topic of PP, the first authors of which were affiliated with Russian institutions. The following were excluded: duplicates; publications not related to first aid; historical and journalistic materials; publications on veterinary medicine; works without specifying the affiliation of the authors; normative legal acts; articles in all languages except Russian. To save bibliographic records and create a catalog of publications, the bibliographic information management program Zotero (Corporation for Digital Scholarship, USA; version 6.0.26) was used. Research results and their analysis. The search identified 1459 bibliographic records. During the screening, 608 publications were excluded. Thus, the sample for analysis included 851 publications. During the study, a clear trend towards an increase in the annual number of publications on PP was revealed – linear regression: R2=0.898, p<0.001. A statistically significant increase in the annual number of publications by Russian authors in Russian devoted to first aid issues was noted. In the last five years, this figure ranged from 66 to 105 publications per year, compared with one to 26 publications per year during the first ten years of the period studied (2003–2012). The increase in the annual number of published works indicates a gradual increase in the interest of Russian authors in the topic of first aid.

Published: June 2024

Purpose. The research is aimed at substantiation of the effective method for mining thin slope ore bodies occurring in soft unstable host rocks by optimizing the breaking process, while determining the patterns of blast energy impact on the disturbed mass by explosive charges with controllable density, taking into account the geomechanical rock mass state. Methods. The research uses a comprehensive approach, including analysis of literature sources, practical experience of mining the slope ore bodies in difficult mining-geological conditions, modeling of the energy characteristics of blasts and wave action on the mass using software, as well as conducting experimental-industrial tests in the Akbakai mine. Findings. An innovative method for effective and safe ore mining from thin slope ore deposits in masses with weakened host rocks has been substantiated and developed. It implies the use of a new construction and location in the blast-holes of a charge consisting of mixed low-density explosives with widely controllable characteristics and with which the blast-holes are charged in two layers with different densities of explosives and detonated at different delay intervals. The optimum delay intervals have been determined, which improve the conditions for controlling the blast energy by changing the direction of the blast action vector towards the newly outcropped surfaces formed in the rock mass after the blasting the first stage charges. The main factors influencing the ore delivery range when mining thin slope ore bodies with blast delivery system have been revealed and methods for increasing this process efficiency are proposed. Originality. New parameters of drilling and blasting operations have been determined for the conditions of mining thin slope ore bodies of the Akbakai deposit: a rational charge construction with controllable blast characteristics has been deve-loped; the optimum range of blast-hole charging density with mixed low-density explosives and delay intervals have been substantiated; a new exponential dependence of the ore delivery range on the specific blasting agent consumption and the angle of the ore body occurrence has been revealed. Practical implications. Practical significance is in increasing the efficiency of blast breaking of minerals, improving the quality of blast delivery of broken ore to loading sites while maintaining the host rock mass continuity and reducing the ore mass dilution, eliminating the formation of large-sized pieces that complicate the blast delivery of the broken ore.

Published: June 2024

Purpose. The research aims to determine the parameters for the overlying stratum caving zones above the mined-out space during repeated mining of pillars at the Zhomart Mine of the Zhaman-Aybat field for the purpose of predicting hazardous zones of influence of mining operations. Methods. Research includes an analysis of the results of previous in-situ studies conducted using seismic surveys, as well as modeling with the Examine2D software to determine the stress-strain state of the overlying stratum mass. The elastic and strength characteristics of an anisotropic mass are used for modeling, taking into account the generalized Hoek-Brown criterion with the Geological Strength Index (GSI) based on a geomechanical description of the mass quality. Comparative analysis of modeling results with seismic survey results is conducted to confirm the effectiveness of the developed methodology. Findings. The research provides an opportunity to determine the overlying stratum caving parameters, such as the caving arch height and the condition for complete undermining of the overlying stratum at the Zhaman-Aybat field at different spans of the mined-out space (from 50 to 350 with a step of 50 m, reaching the maximum span of 370 m). Originality. . It has been determined that the caving arch height depends on the outcrop span and increases exponentially (hcav = 16.473 e0.008Le). In addition, the condition of the earth’s surface complete undermining has been identified depending on the depth of the site to be gotten. Practical implications.The research results can be used to develop a normative document for calculating the earth’s surface shear during the repeated mining of pillars at the Zhomart Mine of the Zhaman-Aybat field. The data obtained will also be useful in planning repeated mining and predicting the earth’s surface shear to avoid negative impacts of mining operations on surface structures.

Published: June 2024

Purpose is to identify vertical displacements of the “soil basem strengthened with piles or micropiles based upon drilling-mixing technology” system relying upon parametric analysis of strain state of the mentioned system, and arrangement of the strengthening elements. Methods. Mathematical modeling took place for twelve finite-element models using the computing complex SCAD intended to analyze strength of structures by means of finite-element method. Numerical analysis was carried out with variation of elastic-strain modulus of vertical reinforcing elements and change in distance between them (3d and 6d of micropiles). Findings. Results of parametric analysis have been obtained for a model without a micropile (non reinforced soil base); a model with a single micropile; a model with two micropiles where distance between them is 1.5 m, i.e. 3d of micropiles; and a model with two micropiles where distance between them is 3.0 m, i.e. 6d of micropiles. The performed comparative analysis has made it possible to obtain the results proving the hypothesis by the authors as for the specific nature of vertical displacement formation of the “soil base strengthened with piles or micropiles based upon drill-mixing technology” system. Originality. It has been identified for the first time that basing upon the standardized document for the auger or displacement piles, it is impossible to decrease efficiently vertical displacements while approaching micropiles since distance between the micropiles is 3d for elements, developed on the basis of the drilling-mixing, is minimal. Practical implications. The obtained results of a strain state may become the keystone for the development of the genera-lized strain theory of the composite “soil base strengthened with piles or micropiles based upon drilling-mixing technology” system as a medium differing in minor changes of strain characteristics.

Cardiac remodeling is a significant issue involving molecular, cellular, and interstitial changes that affect the size, mass, integrity, and function of the heart following a myocardial infarction (MI). We hypothesized that therapy with mixed herbal extracts has a protective effect in mouse models of MI. The underlying mechanisms are thought to be protective against left ventricular (LV) remodeling through reduced collagen deposition. We therefore studied the effects of mixed herbal extracts commonly used in various ways in the belief that they have beneficial effects on cardiac disease. MI was induced by left anterior descending (LAD) coronary artery ligation in switch albino mice. Ethanol extracts of herbs Arjuna bark, oleander leaves, ginseng root, garlic, cardamom seeds and oregano leaves were prepared by ethanol extraction and rotary evaporation technique of dried herbs and then mixed the extracts to make a therapeutic cocktail. The mixture is then administered orally by lavage for 28 days. At the end of 28 days cardiac tissues were harvested and stored for histopathology analysis and assessment of SOD levels. Survival curve data over a period of 28 days showed significant (P<0.05) differences between groups and mortality was reduced in the herbal extract treated group. Heart mass especially ventricular and atrial space and ratio of ​​infarct to total heart area revealed better improvement in treated group compared to untreated group. Histopathological studies showed that the myocardium of the herbal extract treated group had fewer collagen fibers than the non-treated group. SOD activity levels were up-regulated in animals treated with herbal extracts indicating reduction of oxidative stress by herbal extract mixture. Hence, their effects reduce collagen deposition, reduce LV mass and prevent myocardial tissue damage, reduce structural changes and increase survival by their anti-stress effects. Mixed herbal tonic may provide a new therapeutic approach in ischemic cardiomyopathy and ischemic heart failure.

Published: June 2024

The experiment was conducted to compare the effect of different sources of lysine on growth performance, carcass yields and serum biochemical parameters in broiler. A total of 400 Arbor Acres straight run chicks were randomly assigned into 4 different treatment groups for five weeks. The treatment groups were; T1 (100% Ajinomoto lysine), T2 (100% CJ lysine), T3(100% Natural lysine) and T4(50% Ajinomoto + 50% Natural lysine). Each treatment consisted of four replicates and of each 25 chicks. Throughout the experiment body weight, body weight gain, feed intake and feed conversion ratio were recorded as growth performance. Carcass characteristics and blood biochemical profile were also taken after the end of feeding trial. The supplementation of different sources of lysine with feed had significant (P<0.05) effect on growth performances. Results showed that CJ lysine treated broilers had significantly (P<0.05) higher body weight and body weight gain at the end of the experiment compared to Ajinomoto and Natural lysine treated groups. FCR was improved significantly (P<0.05) in CJ lysine group (1.56) compare to the Ajinomoto group (1.69) and Natural lysine group (1.68). Abdominal fat weight showed significant (P<0.05) variation among different treatment groups. Based on the results of this study, it may be concluded that the supplementation of Ajinomoto lysine, CJ lysine and Natural lysine with feed could improve growth performance of broiler and CJ lysine could be considered as performance enhancer in broiler production.

Published: June 2024

Seventeen microsatellite loci from the non-recombining region of the human Y chromosome were typed using AmpFlSTR® Yfiler® PCR amplification systems in 404 male subjects belonging to the three largest ethnic groups in Bangladesh. A total of 150 haplotypes from the Chakma, 144 from the Tripura, and 110 from the Khasia were detected with a corresponding discrimination capacity of 73.885%, 65.563%, and 81.250%, respectively. The highest allele frequency of 0.828 was detected in DYS391 locus in the Tripuras, while the lowest allele frequency of 0.009 was detected at the same locus for the Chakma population. The highest gene diversity (0.964) was observed at DYS385a/b locus in the Khasias, while the lowest gene diversity (0.301) was detected at DYS391 locus in Tripuras population. The overall haplotype diversity for the studied populations was 0.986141. Both the Neighbour-Joining tree and pairwise genetic distances showed that Chakma lies closer to a clade consisting of Tripuras (Khagrachari, Bangladesh) and Tripuri (Tripura, India). In contrast, the Khasias demonstrated a close affinity with the Oraon (Chhattisgarh, India), followed by the Santals. The Y-STR haplotype matching probabilities within and between populations demonstrated that the Chakma, Tripura, and Khasia were 100% genetically distinct. The studied ethnic populations exhibited higher frequency for haplogroups L and Q as opposed to haplogroups R1a, H, and L found in the mainstream Bengali population. The Median-joining networking showed haplogroups L and R1a have the most compact clustering within populations, followed by haplogroups Q and H. The presence of haplogroup R1a suggests that Bengali may have originated through west-to-east migration, whereas haplogroups L and Q distribution in the studied tribes reveal a very significant affinity with the South-East Asian populations and may have shared a common ancestral origin with the Mongoloid stock populations.

Authors: Mamun Sumaiya , Nahar Naznin , Ata Ullah Mohammad , Abduz Zaher Mohammad , Paul Trisha
Published: June 2024

Fish is a rich source of quality protein and fatty acids. Bangladesh's average daily fish consumption is 67.8 grams per people. Fish species are also prone to heavy metal contamination from their surrounding environment. The main objective of this research was to assess the degree of risk associated with the consumption of various fish species in Dhaka, Bangladesh. Three fish species—Tilapia (Oreochromis mossambicus), Shorputi (Systomus sarana), and Mola (Amblypharyngodon mola)—from three local markets in Savar Union, Dhaka, Bangladesh, were selected for analysis. The Kjeldahl technique, Folch method, and several formulae were used to determine the protein, fat, ash, and moisture content for the proximate analysis. The concentration of heavy metals was determined using Atomic Absorption Spectrophotometry (AAS). The estimated daily intake (EDI), target hazard quotient (THQ), total target hazard quotient (TTHQ), hazard index (HI), and cancer risk (CR) were used to evaluate the danger to human health. Tilapia had the highest moisture and lipid content, whereas Shorputi and Mola had the highest protein and ash contents, ranging from 20.77% to 18.16%, respectively. The mean concentration of heavy metals in fish was determined to be Pb>Ni>Cr>Cd in this study. Every fish species had extremely high levels of lead (Pb), with the Shorputi fish having the highest levels. Fish from the Shorputi species had the highest EDI value. Pb>Ni>Cr>Cd was the trace element EDI for adults. Among all species, only Pd had a THQ value higher than 1. The CR value across all species were within E-3 and E-6 range, while the HI value was >1. In conclusion, the highest average Pb concentrations were detected in Shorputi, while the highest amounts of Cd, Cr, and Ni were observed in Tilapia. The findings of this study recommended that the Bangladeshi government regularly assess the levels of dangerous heavy metal and metalloid contamination in the daily meals of its citizens in order to enforce regulatory limits and determine the likelihood of long-term exposure.

Published: June 2024

Background: This study investigates the prevalence and characteristics of E. coli resistance patterns, focusing on isolates from patients with urinary tract infections (UTIs), diarrheal illnesses, and healthy controls. Methods: The study collected and identified E. coli isolates from 36 individuals: 17 with UTIs (urine samples), 6 with diarrhea (stool samples), and 13 healthy controls (stool samples). Antimicrobial susceptibility testing (AST) was performed to assess resistance against ten antibiotics from eight classes. Fluoroquinolone resistance was further evaluated against four drugs (nalidixic acid, ciprofloxacin, ofloxacin, and moxifloxacin). Additionally, molecular analysis of quinolone resistance-determining regions (QRDRs) in gyrA, gyrB, parC, and parE genes was performed on two selected isolates (U44 and U46) by genome sequencing. Results: Chloramphenicol and meropenem displayed the highest efficacy (>70% sensitivity), while AZM, AML, NA and SXT showed the highest resistance. UTI isolates exhibited higher resistance than diarrheal and healthy control counterparts. Worryingly, 58% of isolates exhibited multidrug resistance (MDR), with most (13/21) originating from UTI patients. The presence of MDR E. coli in five healthy individuals suggests potential carriage and community transmission. Fluoroquinolone resistance was particularly alarming, with moxifloxacin showing the highest resistance (80.95%).  Molecular analysis confirmed mutations in all three fluoroquinolone resistance determining genes except gyrB. S84L and D87N dual mutations in the QRDR of gyrA was found in both isolates. S80I and S458A single mutations were observed in parC and parE, respectively. Conclusion: The study findings highlight the widespread prevalence of antibiotic resistance in E. coli and the urgent need for alternative treatment strategies.

Background: High population density makes Bangladesh more vulnerable to a pandemic situation like COVID-19. It is evident from the scientific literature that proper nutritional practices might be effective in preventing various infections. The objective of this research work was to explore the nutritional as well as lifestyle practices among the urban-rural residents of Jashore district and to assess the association of those practices with their residential settings. Methods: It was a cross-sectional study where about 134 respondents (18-50 years) were selected by convenience sampling method from eight rural and seven urban areas of Jashore district in Bangladesh. Association between residence type and various concerned practices have been explored by Pearson chi-square test, binary and multinomial logistic regression analysis. Results: It was found from the results of binary and multinomial logistic regression that, the intake of vitamin D rich foods (OR: 3.45; 95% CI: 1.48,8.07), folic acid rich foods (OR:0.20; 95% CI:0.09,0.46), vitamin B12 rich foods (OR:0.11; 95% CI:0.02,0.52), iron rich foods (OR:0.23; 95% CI:0.08,0.66), and melatonin rich foods (OR:0.15; 95% CI:0.05,0.40) were significantly associated (P<.05) with residential area (urban and rural) of the respondents. On the other hand, no association was found (P>.05) between other immune-boosting nutrient-rich foods such as complex carbohydrates, polyunsaturated fatty acid, vitamin A, vitamin E, vitamin C, Pyridoxine, zinc and selenium rich foods and respondents’ residential area. Moroever, the association was not observed (P>.05) in case of supplement intake of various immune boosting nutrients and area. Among the lifestyle practices, no significant association was found regarding sleep patterns among the respondents but various daily physical movements (OR: 0.19; 95% CI:0.07,0.48) were found higher among the rural respondents. Conclusion: Daily intake of vitamin D rich foods was found higher among the urban respondents but daily intake of folic acid, vitamin B12, iron and melatonin rich foods were found higher among the rural residents. It was also observed that the physical activities were better maintained among the rural respondents than their urban counterparts.

Background: More than 200 viruses can cause respiratory tract infections. It is clinically indistinguishable to differentiate SARS-CoV-2 viral infections from other viruses that cause flu-like symptoms. This study was done to determine the infection and co-infection patterns of common respiratory tract viruses in patients with flu-like symptoms attending a fever clinic during the COVID-19 pandemic.
Methods: A total of 288 participants attending the Fever Clinic of Bangabandhu Sheikh Mujib Medical University having respiratory symptoms were enrolled in this cross-sectional study done from November 2021 to March 2022. Nasopharyngeal swabs were obtained for molecular detection of selected respiratory viruses by multiplex polymerase chain reaction.
Results: The study participants were aged 18 to 72 (mean 33.2) years. SARS-CoV-2 infection was 16.7% among the participants, while other respiratory viruses were 24.3% that included rhinovirus (14.6%) followed by adenovirus (5.6%) and parainfluenza viruses (3.5%). SARS CoV-2 and rhinovirus (29.4%), adenovirus and rhinovirus (23.5%), and rhinovirus and parainfluenza virus (17.6%) were the most common co-infections among them (n = 17).
Conclusion: Nearly 17% infections were caused by SARS-CoV-2. Rhinovirus infection was the second most common of other  upper respiratory viral infections. There is also evidence of co-infections between SARS-CoV-2 and other common upper respiratory tract viruses.

Empowering Bangladesh: A Study on Synergizing Renewable Energy and Smart Grid Technologies for Sustainable Development
Authors: Maruf Hasan , Nipun Murad Kabir , Khan Habeeb Faruk , Ahmed F A Sabbir , Md Moniruzzaman
Published: June 2024

This paper shows a study of the Smart Grid in Bangladesh, emphasizing the incorporation of renewable energy sources. Its aim is to provide an overview of global renewable energy demand and highlight the significance of a smart grid system in fostering sustainability and dropping CO2 emissions.The total renewable energy generation of Bangladesh stood at a meager 1.34% in 2009, representing its low comparative position with other nations. Unfortunately, there has been a little improvement over time, as the total renewable energy generation was 1.51% in 2014 and only slightly increased to 1.57% by 2019. To overcome the addressed issue, it requires massive potential of renewable energy sources to ensure a lucrative, secure, and high-quality supply. This can be achieved through effective monitoring and control mechanisms within the grid system.The integration of cutting-edge technologies such as bi-directional current flow, bi-directional communication systems, automatic working capacity, automatic control systems, and rear systems are required if the upgradation of the current power structure is needed. These advancements will contribute to the enhanced performance, reliability, and security of the renewable energy infrastructure. By embracing a smart grid system and optimizing the integration of renewable energy, Bangladesh can pave the way towards a sustainable future. This will not only boost the country's renewable energy generation but also play a vital role in mitigating CO2 emissions.
