Photocatalysis remains a promising solution for water treatment due to its efficiency, sustainability, and ability to degrade a wide range of contaminants. This study explores the green synthesis of zinc oxide (ZnO/GS) doped with varying weight percent of nitrogen (N) as a photocatalyst. ZnO/GS was synthesized via co-precipitation with zinc nitrate hexahydrate and papaya leaf extract in an aqueous solution, which will be further doped using urea as nitrogen doping. Characterization techniques, including FESEM, EDX, FTIR, and XRD, were employed to analyze the morphology, structural characteristics, surface, and pore volumes of nitrogen-doped green synthesized zinc oxide (N-ZnO/GS). The photocatalytic performance of these samples was evaluated through the photodegradation of methylene blue dye under visible light irradiation. The sample with 10wt%, which is 1 g of dopant, exhibited the optimal results, indicating a homogeneous surface and high crystallinity of N-ZnO/GS synthesized via co-precipitation, demonstrating the best photodegradation efficiency in the photocatalysis process. The findings suggest potential applications in environmental remediation through the degradation of organic pollutants, enhancing wastewater treatment efficacy.

Brazilian agriculture faces the challenge of adopting sustainable practices that reduce costs and mitigate environmental impacts. The use of cover crops stands out as an efficient alternative to improve soil conditions and increase the productivity of subsequent crops. This study aimed to evaluate the effects of different cover crops on the productivity and phytotechnical characteristics of corn. The experiment was carried out in a completely randomized design, with four replicates, considering the following treatments: sorghum (Sorghum sp.), brachiaria (Brachiaria ruziziensis), crotalaria (Crotalaria juncea), fallow and no cover. The production of green mass of the covers, plant height, stem diameter, number of grains per ear, 1000-grain weight and productivity were evaluated. Sorghum showed the highest biomass production (96,498.5 kg ha⁻¹), while fallow was the least efficient. Cover crops provided better corn performance in height, number of leaves, stalk diameter, productivity and thousand-grain weight, compared to areas without cover or fallow. Sunn hemp stood out for biological nitrogen fixation, while brachiaria and sorghum reduced weed infestation and improved water retention. In fallow or uncovered areas, corn had a stalk diameter up to 6.42 mm smaller and productivity reduced by up to 3,827.47 kg ha⁻¹, compared to the best treatments. The results demonstrate the benefits of cover crops, promoting sustainable management and increasing corn productivity and resilience, especially in regions with edaphoclimatic challenges.

The first Algerian implantation of artificial reefs in Oran coastline was carried out on an experimental basis with the main objective to diversify and increase fishing potentialities along the Algerian coasts. University Oran1 Ahmed BENBELLA, the marine ecology association Barbarous, the Directorate of Fisheries and Fishery Resources of Oran (DPRH), and the Ministry of Fisheries and Fish Resources (MPRH) sought to direct fishing to a more sustainable fishing with more appropriate resource management. To this end, an artificial reef was implanted in order to increase biodiversity and fish biomass. O.R.1 (Oran Reef one) consisted of 68 modules, with  two structures of 34 modules; each structure had a superposed form to create a chaotic structure (one to the East, and one to the West), with a total surface of 15 m2. Immersion was at 30m depth on a sandy substrate, with the immersion campaign lasting for 4 months, from April to July 2015. The scientific monitoring of the artificial reef allowed the authors to follow the evolution of structures (e.g., siltation) and biomass estimation of fauna and flora inhabiting the structure. After six months of immersion, monitoring in and around both structures reported the presence of more than 37 species, distributed among algae, mollusks gastropods, sponges and fish. Also, it was noticed that the number of species inventoried near the reef had been increasing since the beginning of monitoring, especially the biomass of fish such as red porgy, common two-banded seabream, black head seabream, amberjacks, scorpionfish, rainbow wrasse, and comber.
HighlightsThe study successfully located and marked the submerged reef by installing measuring devices to facilitate future management efforts. After six months of scientific monitoring, the findings revealed significant ecological and economic improvements. The overall richness of the reef increased by a factor of 9.25, indicating substantial ecological recovery. Additionally, the number of fish species observed on the reef has grown, accompanied by a notable recruitment of new individuals. Furthermore, the biomass of three economically valuable fish species increased by approximately 35 kilograms, yielding an economic benefit of 26,100 Algerian dinars per kilogram, equivalent to 144.73 euros per kilogram. These results underscore the reef's ecological recovery and its potential economic contribution to local fisheries.
Deciphering the anticancer potential of Lannea coromandelica targeting apoptosis signal-regulatory kinase 1 via advanced computational biology approaches
Authors: Ahmed Sheikh Sunzid , Rahman M Oliur
Published: February 2025

Colorectal cancer (CRC) is one of the leading causes of cancer-related mortality globally. The rising expenses, significant side effects, and increasing resistance to traditional CRC treatments suggest the critical need for new and more effective therapeutic options. This study explored the anticancer potential of Lannea coromandelica  (Houtt.) Merr. phytocompounds targeting the promising apoptosis signal-regulatory kinase 1 (ASK1) protein using computational biology approaches including molecular docking, ADMET analysis, molecular dynamics (MD) simulation, and MM/GBSA calculations. Virtual screening of the 17 phytoconstituents identified two lead compounds: ellagic acid and physcion, with binding affinities of -9.6 kcal/mol and -9.3 kcal/mol, respectively. ADMET analysis revealed favorable pharmacokinetic, pharmacodynamic, and toxicity profiles for the lead compounds. MD simulations supported the stability and compactness of the two leads in comparison to the control drug erbitux for 200 ns. The lead compounds displayed fewer rotatable bonds compared to Erbitux, resulting in lower torsional flexibility and greater stability during the simulations. PCA-based essential dynamics analysis demonstrated highly similar global motions in phase space for both lead compounds and erbitux, indicating comparable dynamic properties. Free binding energy calculations identified ellagic acid (-69.20 kcal/mol) as the superior lead compound over physcion (-65.68 kcal/mol). These results may open new avenues for the development of novel drug candidates targeting colorectal cancer.

Authors: Akter Suma , Naznin Mohosina , Khan Md Harunor Rashid
Published: February 2025

Global demand for vegetable crops has surged in this era of globalization and increased health awareness. Due to its rich nutritional and chemical composition, tomato (Solanum lycopersicum L.) has become one of the most popular and widely consumed vegetables worldwide. In response, a field experiment was conducted in net house at the Department of Soil, Water, and Environment, University of Dhaka, Bangladesh, to evaluate the effects of organic fertilizers, both alone and in combination with mulching, on the nutrient content and biomass allocation of tomato plants. The results indicated that the application of organic fertilizers such as mustard oil cake (MOC), poultry manure (PM), and vermicompost (V) at higher rates (8 t ha⁻¹) significantly increased the nutrient contents (N, P, K, S, Ca, and Mg) in the leaves, stems, and roots of tomato plants in absence of mulching. However, applying these fertilizers at lower rates (4 t ha⁻¹) in combination with mulching also effectively enhanced nutrient content. Regarding biomass allocation, particularly the root-to-shoot ratio, a slight anomaly was observed. The highest root-to-shoot ratio was recorded in the control plot, suggesting that factors other than nutrient supply, such as root penetration depth, distribution in the soil, response to transient drought, initial root growth and also environmental or physiological conditions, might have influenced root weight. Therefore, variations in root-to-shoot ratios could be misleading from a physiological perspective. To meet the growing demand for high-yielding, fertilizer-responsive crops, there has been significant reliance on synthetic inputs, raising concerns about the long-term sustainability of agricultural systems. Thus, environmentally friendly farming methods are urgently needed to ensure sustainable food production. The combination of mulching and organic fertilizers presents an effective strategy for improving crop growth conditions, increasing yield, and enhancing product quality by mitigating unfavorable environmental conditions.

Published: February 2025

Salad vegetables are widely eaten raw in Bangladesh because of their high nutritional content and health benefits. However, contamination of salad vegetables with parasites poses a significant health risk. This study aimed to document the parasitic contamination of raw salad vegetables sold in local markets of Dhaka and the role of vendors’ hygiene practices in transmitting parasitic pathogens. 29.6% of the salad vegetables were contaminated with 8 different parasites. Ascaris sp. (20.4%) > Entamoeba sp. (13.0%) > Hymenolepis sp. (11.1%) > Cystoisospora sp. (5.6%) >Hookworm (3.7%), Trichuris trichiura (3.7%) > Taenia sp. (2.8%). Leafy vegetables (coriander 66.7%, mint 44.4%, lettuce 38.9%) were more contaminated than nonleafy vegetables (carrot 11.1%, Tomato 11.1%, cucumber 5.6%). The vendors’ hygiene practices: the habit of washing hands with soap and nail status, and infected vendors were proved to be the statistically significant contributing sources of observed parasitic contamination. The present study demonstrated the presence of infective stages of different pathogenic parasites on the surface of raw salad vegetables. It establishes a relationship between vendors’ hygiene practices and parasite transmission. Eating them may spread vegetable-borne diseases in Dhaka unless adequately cleaned and disinfected prior to consumption.

Published: February 2025

A field experiment was carried out in Habiganj, Bangladesh, to evaluate the effects of various organic amendments, including rice straw plus cow dung composts (1:2 and 1:4 ratios), sawdust compost, rice husk compost, vermicompost, and tricho-compost on the yield attributes and protein content of BR 22 rice grown under natural field conditions. The experiment was structured with a completely randomized block design and included three replications. In subplots, organic amendments were applied at varying rates of 0, 5, and 10 tons per hectare. The application of these organic amendments significantly (p ≤ 0.05) improved various agronomic attributes of rice compared to the control plot. Tricho-compost (TC) at 5 and 10 t ha⁻1 ranked 1st and 2nd, respectively, in terms of tillers per hill (45 and 40 at the maximum tillering stage; 42 and 38 at harvest), productive tiller ratio (0.89 and 0.72), straw dry matter production (10.72 and 10.29 t ha⁻1), and grain yield (8.00 and 7.57 t ha⁻1). However, the highest protein content in grains (14.0%) was achieved with vermicompost at its higher dose (T3), followed by TC (T8) and rice husk compost (T13). The study concludes that locally available organic amendments of tricho-compost and vermicompost found to be significantly (p ≤ 0.05) improve rice yield and protein content, making them a viable option for sustainable rice production.

Published: February 2025

Biochemical activity and its stability of Oxalis corniculata L. leaf extracts in methanol, cyclohexane and water were investigated in this study. Preliminary phytochemical screening of the total phenolic and flavonoid contents for the methanolic extract were estimated as 18.63 ± 0.55 mg gallic acid equivalent and 6.46 ± 0.85 mg quercetin equivalents per gram of fresh leaf respectively. Maximum flavonoid content was observed in cyclohexane extract and the phenolics of aqueous extract were relatively stable as compared to the other extracts. The estimated total antioxidant capacity and the total reducing power of methanolic extract were the highest among the extracts, and were 12.33 ± 0.54 mg and 3.79 ± 0.37 mg ascorbic acid equivalent per gram of fresh leaf respectively. The IC50 values of DPPH free radical scavenging activity and hydrogen peroxide scavenging activity of the methanolic extract of fresh leaf were 10.14 ± 0.04 mg and 11.1 ± 0.01 mg, respectively. Such activities were absent or negligible in other extracts. Thin layer chromatographic studies detected the presence of at least two compounds with potent antioxidant activity. However, the phenolic and flavonoid contents, and all biochemical activities of the extracts were reduced after six months of preservation at -20oC. These data indicated that freshly prepared methanolic extract of O. corniculata could be the most potent, and such fresh preparation should be used to attain the desirable biochemical activities.

This study evaluated the effects of micronutrients (B, Fe and Zn) on the vegetative growth and shoot nutrients (K, Ca, Fe and Zn) status of chickpea (Cicer arietinum L.) grown under different moisture regimes (50%, Well-Watered; 25%, Mild-Stressed and 12.5%, Severe-Stressed) in greenhouse condition. Micronutrients were supplied alone and in combination as foliar spray to plants with severe-stressed condition. Results showed a significant decline in shoot height (p < 0.0001), fresh weight (p < 0.0001), dry weight (p < 0.0001) and relative water content (p = 0.0001) from well-watered to severe-stressed condition, although no remarkable change was observed after the application of micronutrients. Significant reduction in root fresh weight (p= <0.0001) and dry weight (p = 0.0071) was also seen in severe-stressed condition compared to that in the well-watered condition. Micronutrients were found to stimulate growth of root dry weight and root length under severe-drought condition. Significant increase of leaf area (p = <0.0001) and decrease of leaf chlorophyll content (p = <0.0001) were noted under severe-drought condition compared to that of well-watered condition. Concentrations of K, Ca, Zn and Fe increased in plant shoot tissue after the application of micronutrients although depending on the combination of treatments. Results thus indicated a promising role of micronutrient use in the amelioration of drought stress for the cultivation of chickpea.

Four antagonistic potentials of soil fungi comprising three species of Aspergillus viz., A. flavus Link, A. fumigatus Fresenius, A. niger van Tieghem and species of Trichoderma viride Pers. were used against six important rice pathogenic fungi (i.e. Bipolaris oryzae (Breda de Haan) Shoemaker, Curvularia lunata (Wakker) Boedijn, Fusarium equiseti (Corda) Saccardo. Fusarium fujikuroi Nirenberg, Microdochium fisheri Hern.-Restr. and Crous. and Nigrospora oryzae (Berk. & Br.) for the purpose of biological control. In dual culture colony interaction out of four antagonistic fungi, T. viride showed the highest growth inhibition (87.15%) against Fusarium fujikuroi. The maximum inhibition (82.63%) of radial growth of the test pathogens were observed in case of T. viride owing to the volatile metabolites. On the other hand, the highest amount for the effect of non-volatile metabolites of T. viride on N. oryzae and F. fujikuroi at 20% concentration. The present investigation suggests that the isolates of Trichoderma is a biocontrol agent that can help control seed borne fungi in rice.

Published: February 2025

In today’s digitalized modern society people are getting affected by the practice of fast fashion buying and become the victims of post purchase indecisions and social media addictions. Understanding how young adults’ cognitive dissonance and sense of self-worth are related to fast fashion was one of the main goals of the current study. The present study also investigated whether any other factors, such as gender, social media addiction in terms of online shopping, educational background, and income, might have an impact on the study’s results. Women who purchase fast fashion are more likely than males to experience cognitive dissonance when making a purchase, according to the present study results. Fast fashion and cognitive dissonance following purchase are discovered to have a positive relationship. Regression analysis determined that fast fashion and social media can predict cognitive dissonance after making a purchase as well as three sources of self-worth: appearance, God’s love, and virtue. The results of the current study show a relationship between social media use and how it affects customer behaviour in the fast-fashion clothing sector, which may cause cognitive dissonance. Furthermore, there is evidence that social media use and rapid fashion have a negative impact on academic achievement, psychological health, and self-worth. Interestingly, the study shows that under this situation, women are more likely than males to experience cognitive dissonance. In conclusion, fast fashion plays a much greater role in our lives than we realize in terms of affecting our self-worth and cognitive dissonance and using of social media to for purchase purposes.

Introduction:The COVID-19 Pandemic has had a profound effect on the psychology of people around the world. It posed fear and anxiety to all, and pregnant women became more vulnerable. Various factors and the scarcity of treatment and hospital facilities during the lockdown worsened the mental state. 
Aim:The study was performed to assess pregnant women's psychological impact and anxiety during the COVID-19 pandemic using a preset validated questionnaire.
Methodology:This cross-sectional study was conducted among 553 pregnant women, who visited for antenatal care in the outpatient department of Obstetrics and Gynecology, Chittagong Medical College Hospital, and private chambers of researchers from October to December 2020.
The psychological impact of the COVID-19 pandemic on pregnant women was assessed by the Italian version of the Impact of Event Scale (IES-R) questionnaire. A score of >24 was taken as significant. A six-item short-form of the Spielberger State-Trait Anxiety Inventory (STAI-6) scale was used to measure anxiety, and a score >36 was considered significant. Data were analyzed with SPSS-22 using the Chi-square test (for categorical data) and t-test (for numerical data) as appropriate. The NOVA test was done to calculate the significance between the groups. The P values <0.5 were taken as significant.
Results: Among the participants(N-553), more than half (54%) of the participants had different grades (mild-27%, moderate-09%, and severe-18%) of psychological impact during the COVID-19 pandemic. The Mean (±SD) total IES-R score was 25.65(± 12.334) (range: 0-68); the STAI-6 score was above the cut-off value (i.e., > 36) [40.50 (± 15.027)] (range: 5-77). Severe IES-R scores were observed in women who attended private chambers than in government hospitals (p<0.001), and also in women among urban patients (p=0.001), middle-income group (p=0.001), and women who did not contact a doctor (p=0.001).
Conclusion: The study revealed that more than half of the pregnant women experienced psychological impact during pregnancy. A subset of them might be vulnerable to PTSD. Almost all of the pregnant women in the study developed anxiety during COVID-19. Identifying protective factors targeted to eliminate the psychological impact and anxiety of pregnant women is warranted.

Background: Assessing admission blood pressure (BP) is crucial in predicting mortality community acquired pneumonia.
Methodology: This was a prospective longitudinal study at DMCH to explore hemodynamic predictors of the 30-day all-cause mortality, including deaths during hospital stay and after discharge in community-acquired pneumonia. Statistical analyses included the Z-proportion test, multivariate logistic regression, and ROC curve analysis. A p-value of less than 0.05 was considered statistically significant.
Results: The study's hospital mortality rate in community-acquired pneumonia was 14%. However, the all-cause mortality rate after 30 days of hospital admission increased to 22.6%. This was significantly associated with systolic blood pressure below 90 mmHg, diastolic pressure of 60 mm Hg or less, pulse of 40 mm Hg or less, and mean arterial pressure below 70 mm Hg (p<0.001). The multivariate logistic regression analysis indicated a significant association between blood pressure parameters and 30-day mortality in community-acquired pneumonia (CAP) patients. Systolic blood pressure (<90 mmHg) was found to be a significant predictor, with an Odds Ratio (OR) of 5.439 (95% CI: 1.565 to 18.895) and a p-value of 0.004. This suggests a significantly higher risk of mortality for subjects with systolic blood pressure below 90 mmHg compared to those with higher readings. However, diastolic blood pressure (<60 mmHg) did not show any significant association, as indicated by an OR of 0.871 (95% CI: 0.336 to 2.256) and a p-value of 0.775. Similarly, pulse pressure (<40 mmHg) did not exhibit any significant relationship with mortality, with an OR of 0.756 (95% CI: 0.090 to 6.377) and a p-value of 0.797. On the other hand, mean arterial pressure (<70 mmHg) emerged as another significant predictor, with an OR of 4.465 (95% CI: 1.280 to 15.579) and a p-value of 0.012. This suggests a significantly higher risk of mortality among subjects with mean arterial pressure below 70 mmHg compared to those with higher values.
Conclusion: Low systolic blood pressure (<90 mmHg) and mean arterial pressure (<70 mmHg) are associated with increased mortality risk in CAP patients.

Background: Snakebites are a neglected public health issue, particularly in rural tropical areas. In Bangladesh, Green Pit Viper bites are common, causing pain, swelling, and coagulopathy, leading to morbidity. Epidemiology of Green Pit Viper biting, frequency of coagulopathy and proper description of clinical features from Green Pit Viper bite is lacking.  This study aims to describe clinical features, coagulopathy patterns, pre-hospital management, and outcomes of patients admitted with Green Pit Viper bite in Chittagong Medical College Hospital. Method: This study was cross-sectional and observational, analyzing medical records and data from the Snakebite Clinic at Chittagong Medical College Hospital (CMCH) in Bangladesh from 1st May 2017 to 30th April 2018. Informed written consent was obtained from patients, and their epidemiological data and clinical findings were recorded in a predefined case report form. The swelling extent was measured by comparing it to the non-bitten limb, and a 20-minute whole blood clotting test (WBCT) was performed in all patients to detect and monitor coagulopathy. Lab coagulation profiles were used to confirm coagulopathy and its reversal. Statistical analysis was conducted using SPSS-23. Results: The study included 112 patients with a median age of 32 years, predominantly adult males from rural areas. Bites commonly occur during outdoor activities. Pre-hospital management practices were widespread, with tourniquets and herbal remedies being common. Swelling was the primary local effect. Notably, 43% of patients developed coagulopathy, often with delayed onset. Most patients reached the hospital within 5 hours of the bite. Coagulopathy reversal was observed, and the majority of patients improved. Conclusions: This study sheds light on Green Pit Viper bites in Bangladesh, emphasizing coagulopathy's significance and the need for specific antivenom.

Background: Dengue fever is a painful febrile illness caused by a mosquito-borne Arbovirus. Epidemic episodes often occur during the rainy season. Complete blood count (CBC) is essential in patients with dengue fever and serological tests are necessary to confirm it. This study aimed to evaluate the hematological changes in dengue fever patients in Jashore Medical College Hospital, Bangladesh. Methods: This prospective cross-sectional study was conducted in the Department of Medicine, Jashore Medical college Hospital, Bangladesh from July 2023 to Decembar 2023. The study involved 177 dengue fever patients identified through NS1 and/or IgM antibody tests. Purposive sampling was used for patient selection, and data analysis utilized SPSS version 23.0. Results: Analysis of hematological parameters on the 1st and 3rd days indicated significant shifts in platelet, leucocyte, neutrophil, and lymphocyte counts. Platelet count decreased from 99.67±96.17 x 109/L to 82.72±60.84 x 109/L (p=0.048). Leucocyte count rose from 6.43±3.01 x 109/L to 7.85±5.58 x 109/L (p=0.003), while neutrophil count decreased from 6.31±1.38 x 109/L to 5.44±1.36 x 109/L (p<0.001). Lymphocyte count also increased from 3.06±1.80 x 109/L to 3.78±1.19 x 109/L (p<0.001). No significant shifts were observed in hemoglobin (p=0.579) or hematocrit (p=0.639) levels. Conclusion: Among dengue fever patients, platelet and neutrophil counts decrease while leukocyte and lymphocyte counts increase significantly between the 1st and 3rd days. However, there are no significant shifts observed in hemoglobin or hematocrit levels in the same tenure.
