The Effect of Acetamiprid Administration on Bcl-2 Immunoreactivity in the Liver
2024
Gökhan Nur
This study aimed to show the effect of acetamiprid, a neonicotinoid insecticide, on B-cell lymphoma 2 (Bcl-2) gene expression, which plays an important role in apoptotic mechanisms in liver tissue. The study consisted of four groups in total, in which three doses of acetamiprid (5, 10, and 15 mg kg-1) were administered, together with the negative group, in which no substance was administered. Liver tissues resected from mice sacrificed by cervical dislocation after 14 days of acetamiprid administration by gavage were fixed in a 10% formaldehyde solution for histological and immunohistochemical analyses and blocked in paraffin after routine tissue follow-up, and sections were stained with haematoxylin-eosin and immunostaining. Histological analysis revealed normal liver tissue in the control group; whereas, sinusoidal dilatation, vasodilatation, and necrosis and steatosis in the parenchyma were found in the acetamiprid-treated group at an increasing rate depending on the dose amount. The immunoreactivity of Bcl-2 in liver tissue was observed in the sinusoidal epithelium. Bcl-2 immunoreactivity was observed severely in the control and 5 mg kg-1 groups and moderately in the 10 mg kg-1 and 15 mg kg-1 acetamiprid-treated groups. Bcl-2 immunoreactivity was observed homogenously in the region from the central vein to the Kiernan’s space. It was observed that acetamiprid used in the study showed a toxic effect on liver tissue, affected bcl-2 expression, an important biomarker in apoptotic pathways, and induced a dose-dependent decrease in bcl-2 immunoreactivity.

Promise Etim | Dominic Ekpo | Inemesit Edem Ekop | Joseph Edet Bassey | Okon Joe Ononokpono | Odudu Gabriel Udobong
A cassava starch extraction machine was designed and fabricated to perform a quadruplet action of grating, washing, sieving and separation. The study was necessitated based on concerns that most locally manufactured cassava processing machines are without provision for the extraction of starch. Food processors mainly depend on the manual pressing of cassava to obtain starch and this has significantly increased the cost of the product in the local market. Materials for construction were locally sourced and the machine was powered by a 2 hp electric motor through a v-belt-pulley transmission system and operating at a speed of 547 rpm. Fresh cassava tubers were harvested from Ikot Akpaden, a rural community in Mkpat Enin, Akwa Ibom, South-South of Nigeria, and used for the experiment. Results from the experiment showed that the quantity of wet starch extracted increased from 0.64 to 1.48 kg as the volume of water mixed with 2 kg of the product increased from 1 to 5 Liters. The rate of water usage and throughput capacity increased from 0.0005 to 0.0025 m3/kg and 35.29 to 46.75 kg/h respectively as volume of water increased. The optimum machine efficiency was 74%. The machine was fabricated at a cost of N 150,200 (equivalent of $100). Minimal time consumption, ease of operation and low production cost were some of the features that made the machine economically viable when compared to other conventional methods of extracting starch from cassava.

Hüseyin Fatih Atlı
Implementing the right strategies in the agricultural supply chain in the supply of seeds, pesticides, fertilizer, energy, fuel and agricultural mechanization tools and equipment has a great role in increasing agricultural productivity. The main purpose of the study is to rank and evaluate alternatives in choosing a sustainable fertilizer supplier in the agricultural supply chain by using AHP-F and ARAS-F techniques. In an environment of uncertainty and complex supply chain structure, multi-criteria decision making (MCDM) methods are widely used to solve supplier selection problems. In this study, the importance levels and weights of the criteria in the selection of sustainable fertilizer suppliers were measured by the AHP-F method. The criteria that are important for fertilizer supplier selection were evaluated by taking expert opinions, the uncertain and uncertain opinions of the decision makers were modeled with the AHP-F approach and the weights of the criteria were determined. Among the criteria, resource consumption (FSC05) has the highest weight. Then, alternative rankings were obtained with the ARAS-F method. Fertilizer supplier alternatives in the agricultural supply chain were ranked with the ARAS-F method, using the criterion weights found with AHP-F. In the ranking of alternatives, alternative fertilizer supplier FS03 ranked first with the highest value. This study provides a resource for businesses and other stakeholders to make decisions regarding sustainable fertilizer supplier selection.

2024
Gülşah Kanbur
Hemp plants are notable for their climate resilience, and hempseed meal (HSM) is a potential high-protein feed for poultry. However, HSM has high levels of the antinutritional factor phytic acid (PA). This study aimed to evaluate the effects of heat and soaking treatments on the protein and PA content of HSM. HSM was obtained through cold pressing of whole hempseed and then subjected to heat treatment at 70°C for 24 hours. Soaking treatments involved water, water-vinegar mix, and vinegar for 1, 7, and 24 hours, followed by drying and analysis of PA and protein content. Results indicated that heating increased PA content without affecting protein levels. Soaking duration did not significantly alter protein content but did affect PA levels, with 24-hour soaking significantly increasing PA compared to 1-hour and 7-hour durations. The soaking material also influenced PA content: water soaking increased PA, while a 1-hour vinegar-water mix and 7-hour vinegar soaking significantly reduced PA. The highest PA concentration occurred with 24-hour water soaking. The protein content was highest with 7-hour vinegar soaking. In conclusion, acidic soaking solutions, particularly vinegar and vinegar-water mix, effectively reduced PA in HSM without protein loss.

This study endeavors to elucidate the factors influencing protein preference and consumption patterns in the Ga South Municipality of Ghana. Understanding these determinants is pivotal for promoting environmentally sustainable and healthy dietary habits. Utilizing a random sampling approach, the study collected 150 meticulously structured questionnaires from a representative sample of municipality residents. It delved into the socio-cultural and economic factors shaping protein preferences and consumption behaviors, alongside investigating the impact of awareness, knowledge, and availability of protein sources on dietary choices. The findings unveiled that respondents partake of protein daily, albeit with variations in patterns based on sources: plant protein consumption occurred weekly, while animal protein was consumed daily. Moreover, respondents exhibited awareness of the nutritional benefits associated with protein consumption. While awareness for protein nutrition is high, the price remains a deterrent to accessing protein in Ga South Municipality. Calling on policymakers to support local food production and supply, invest in food literacy, and develop good transportation to reduce logistics bottlenecks that often create a massive difference between farm gate and market prices.
