Authors: Korsah Samuel 
Published: February 2025

Introduction: The effectiveness of the first-line malaria treatment has been affected by drug resistance and adverse side effects leading to a limited number of treatment options. This calls for the search for alternative antimalarial agents. The study evaluated the in vitro antimalarial activity of six plants frequently used in herbal antimalarial products in Ghana against chloroquine-sensitive strain (3D7) and chloroquine-resistant strain (DD2) of Plasmodium falciparum. Method: Aqueous extracts were prepared from the plants by decoction and freeze-dried. A fluorescence-based SYBR Green assay was used to evaluate the antimalarial activity of the extracts against Plasmodium falciparum strains 3D7 and DD2. Also, the cytotoxic e?ects (CC50) of the plant extracts against red blood cells were evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) rapid calorimetric assay technique. Results: Alstonia boonei, Cryptolepis sanguinolenta, and Azadirachta indica were the most effective mono-herbal extracts with IC50 of 8.64 ?g/mL, 6.12 ?g/mL, and 5.22 ?g/mL respectively against 3D7 lab strain and 8.47 ?g/mL, 5.12 ?g/mL and 5.22?g/mL respectively against DD2 lab strain. The aqueous extracts of Paullinia pinnata, Citrus aurantiifolia, and Tetrapleura tetraptera exhibited moderate activity against both lab strains with IC50 values of 24.72 ?g/mL, 34.89 ?g/mL and 14.94 ?g/mL respectively against 3D7 strain and 14.84 ?g/mL, 31.01 ?g/mL and14.74 ?g/mL respectively against DD2 strain. All plant extracts exhibited no cytotoxicity against RBC (?100 ?g/mL, except Cryptolepis sanguinolenta with CC50 92.7 ?g/mL). Moreover, except Paullinia pinnata, Citrus aurantiifolia and Tetrapleura tetraptera (with low selectivity index: SI < 10), all the plants displayed a good selectivity index (SI>10). Conclusion: All six frequently used antimalarial plants in monotherapy possess significant antimalarial activity against Plasmodium falciparum (3D7) and (DD2) strains. The data obtained from this study support the folkloric and frequent use of these plants in several herbal antimalarial products on the Ghanaian market.

Authors: Stuckey Julie , Snodgrass Lisa Lambert 
Published: February 2025

This pilot study uses a mixed-method convergent design to explore what formal policy and informal practices exist at Hispanic-serving institutions (HSIs) and emerging Hispanic-serving institutions (eHSIs) in states with restrictive, ambiguous, or no undocumented student legislation. These policies and practices can be used to increase equity access in a biased political environment. Data was collected in two phases. Student-facing staff and administration at HSIs and eHSIs in states with restrictive/ambiguous or no policies completed a mixed-methods survey. Individuals could then choose to participate in a semi-structured interview. Initial results reveal that formal policies are limited to clarifying federal or state legislation. In contrast, informal practices provide ways to provide information and support, professional development, or ways to manage student disclosure of status. Of special interest are “don’t ask, don’t tell” practices that exist when a student’s status is disclosed and the number of respondents who believe no undocumented students are enrolled at their institution. Recommendations include policy and professional development considerations.

A field experiment with onion var. BARI Piaz-1 was conducted in the research farm of Sher-e-Bangla Agricultural University, Dhaka, during the winter season (October to February) to find out the response of boron and calcium on seed yield and quality of onion. The experiment was carried out with four levels of boron viz. B0 (0 ppm), B1 (500 ppm), B2 (1000ppm) and B3 (2000 ppm); and three level of calcium viz. C0 (0 ppm), C1 (2500 ppm) and C2 (5000 ppm). This experiment was laid out in RCBD with three replications. The results showed that the treatments significantly influenced the plant height and number of leaves at all growth stages except harvesting time. At harvest, boron and calcium significantly increased the umbel per plot, flowers per umbel, fruits per umbel, fruit set (%), yield per plant, 1000-seed weight, seed yield per ha, germination and normal seedling percentage; and reduced the abnormal seedling percentage. Combined application of boron and calcium also significantly increased the all above parameters mentioned except abnormal seedling percentage of onion. The highest result of all parameters including yield showed from B3C2 but this treatment reduced production of abnormal seedling. Besides, combined of boron and calcium treatment B3C2 gave the highest plant height, leaf number and chlorophyll content. The application of 2000 ppm of boron together with 5000 ppm of calcium (B3C2) treatment gave the best performance showing the yield and quality of onion seed.

Farmers’ knowledge of using flood forecast information in fish farming: A case of rural Bangladesh
Authors: Shonia Sheheli  , Mst Sharmin Akter  , Md Anamul Haque  , Mohammad Maruf Hasan  
Published: February 2025

The effects of global climate change and extreme weather events are threatening Bangladesh's fish and aquaculture productivity. Given the negative consequences of climate change, both the national and international societies concur that mitigating the effects of climatic unpredictability and change requires the development of weather and climate services. Additionally, if forecasting data is expertly adapted to fish farmers' requirements, they may be better able to handle and adjust to climatic and climatic-induced stressors. The primary goal of the study was to determine how much fish farmers knew about using flood forecast information regarding fish farming. Three villages in the Union Islampur upazila, which is part of the Jamalpur district, were the sites of the study: Kulkandi, Chinaduli, and North-Bamna. A sample of 95 randomly chosen fish farmers (about 25% of the total population) out of 380 fish farmers provided the data. Focus groups, matrix ranking, and key informant interviews were among the qualitative and quantitative techniques used in the study's research methodology. In order to collect both quantitative and qualitative data, formal and semi-structured questionnaires were created. The majority of farmers (53.90%) had a medium level of knowledge, followed by high knowledge (31.57%), and poor knowledge (14.74%) about the use of forecast information in fish farming. Therefore, through a variety of interventions, including training, group discussions, demonstrations, and the distribution of printed materials, concerned authorities like the Department of Fisheries (DOF) should provide chances to increase the knowledge of fish farmers. Regression study revealed that farmers' knowledge regarding using forecast information in fish farming is positively impacted by their level of education, annual earnings from fish farming, organizational participation, and sources of flood forecast information. Therefore, while creating programs and making decisions, legislators, development practitioners, extension specialists, and others should consider these aspects.

Published: February 2025

Background: Squamous cell carcinoma in upper aerodigestive tract is most often caused by smoking. Smokers get laryngeal cancer, while chewers get mouth cancer. With the surge in smokeless tobacco use, it's important to determine if this differentiation influences clinical and pathological characteristics beyond site distribution.
Objective: The purpose of the present study was to assess any relation between tobacco smoking, oral intake of tobacco with betel leaf or tobacco powder and squamous cell carcinoma in upper aero digestive tract.
Methodology: This cross-sectional study was conducted in a single Diagnostic center at Dhaka, Bangladesh for a period of one year from July 2022 to June 2023 on patients presented with histopathologically established upper aerodigestive tract malignancies. Patients age, gender and involved site was taken from the patients report.
Results: Male were predominant than female. Male to female ratio was 3.3:1. Mean age of the patients was 59.26 ± 12.55 years of the male and 56.11 ± 13.13 years of the female. Cancer was more in female at 5th and 6th decade whereas cancer was found more in male at 6th and 7th decade. Most common location of the lesions was sub-glottis (27.6%) and tongue (20.0%). The most common causes of Upper Aerodigestive Tract cancer were smoking (76.2%) and smokeless tobacco using (54.1%). There was no association between smoke and smokeless tobacco with severity of carcinoma. Maximum cases of carcinoma were grade II but there was no significant difference in grade of carcinoma between tobacco smoker and tobacco non-smoker. There was no significant difference in grade of malignancy between tobacco user and non-user.
Conclusion: Smoke and/or smokeless tobacco user have increased risk of development squamous cell carcinoma in upper aerodigestive tract. However, there is no significant difference between incidence and grade of tumor among only smoker, smokeless tobacco user or both.
