Formulation and evaluation of a novel functional cereal containing avocado seed flour
Authors: Koeswanto Arief , Kusuma Karissa
Published: November 2023

Celiac disease is the most common food-sensitive enteropathy in humans, caused by consumption of wheat gluten and linked to proteins found in barley, rye, and oats. A gluten-free diet is the only known cure for celiac disease. Most low gluten foods on the market are high in starch but low in other nutrients, functional ingredients, and health benefits. Avocado is a tropical fruit with a high annual growth rate (19.09%). A large amount of solid seed residue, approximately 21-30% of the fruits, is commonly discarded. Avocado seeds contain a variety of nutrients, including phenolic compounds (flavonoids, polyphenols), fiber, reducing sugars, pentosan, arabinose, and protein, as well as a high starch content of 29.6%. To reduce the levels of sap in avocado seeds, several pre-treatment stages were carried out. The bitter taste of the sap will affect the taste of the final product. Avocado seeds can be ground into flour with a high antioxidant content that is low gluten. Avocado Seed Flour (ASF) is a low-protein flour that can be used to make dough for dry food ingredients such as biscuits and pastries because low-protein flour absorbs less water, making the dough crisper and more resistant to storage. The goal of this study is to create a nutritious and functional low gluten diet cereal formula by replacing wheat flour with ASF.  Cereals with the least amount of ASF were described as having a high grain percentage and crunchiness, whereas cereals with medium and high ASF levels were described as having a darker color and bitterness. Contrary to popular belief, the ASF content of gourmet cereals with the highest ASF content was lower than that of cereals with the lowest content.

Published: November 2023

Background: Knowledge of the concept of pain anxiety is necessary to provide better services in the care of patients suffering from various types of pain. Therefore, the aim of this study was to precept and learn more about the concept of pain anxiety. Methods: This study was analyzed using Rogers’ evolutionary concept analysis approach for articles published from 1975 to 2023. Valid databases, including Google Scholar, CINAHL, Scopus, PubMed, Web of Science, and ProQuest, were used to search for sources. Articles or sources published in the field of nursing and medicine were included in the study, and the existing articles were sorted according to the year of publication to determine the changes in the concept over time. The text of each article was re-read, and related phrases were identified based on their appropriateness, and finally, a new definition of pain anxiety was explained. Results: Pain anxiety indicates cognitive, emotional, behavioral, and physiological reactions to the anticipation and experience of pain, which refers to future fears and concerns about pain. This type of anxiety appears with different words and phrases that represent fear, worry, discomfort, panic, and anger. The antecedents of pain anxiety include chronic pain, procedures such as dressing changes, and injuries such as fractures and burns. The consequences of this concept include physical and psychological problems, such as worsening pain. The word "pain-related fear" can be utilized as an alternative concept. To provide an example of pain anxiety, we can refer to a patient who has no history of surgery, and after performing the first debridement and dressing, avoids debridement and changing the dressing in the following days. Conclusion: This analysis provides a dynamic definition of pain anxiety that may be useful to promote interaction and enhance understanding of concepts.

Authors: Rezaei Mohammad , Amiri Fatemeh , Razaghi Mahta , Mohammadi Farshid
Published: November 2023

Background: Blood transfusion has some complications known as transfusion-related reactions. Accurate identification and recording of these reactions is more important for their management and prevention. This study aimed to evaluate blood transfusion-related reactions in blood recipients in patients in Hamadan Besat hospital during 2020-2022. Methods: In this cross-sectional study, the data of 400 patients who had complications after receiving blood and blood components were collected in terms of hemolytic and non-hemolytic blood transfusion reactions. Data were collected from patients’ medical records and standard blood transfusion checklists and analyzed by SPSS version 26 software using the chi-square test and Fisher’s exact test. Results: Red blood cell (RBC), 70.25%, random donor platelet (RDP), 10.3%, and fresh frozen plasma (FFP), 9.5%, were the most transfused blood components. Blood transfusion reactions were allergic reactions (53.5%), febrile non-hemolytic transfusion reaction (FNHTR) (24%), dyspnea (10.25%), hemolytic reactions (HR) (4.5%), hypotension (4.25%), transfusion-associated cardiovascular overload (TACO) (1.75%), and other reactions (2.75%). A significant relationship was also observed between receiving components containing RBC, including whole blood (WB0), RBC concentrate, and leukoreduced RBC, and the incidence of FNHTR (P=0.001). Conclusion: Based on the findings of the present study, allergic reaction and FNHTR were the most common complications after blood transfusions. Blood transfusion-related reactions could be predicted, managed, and possibly prevented by considering the relationship between the type of reaction and the type of transfused blood components.

Authors: Mokri Pardis , Rahimian Zarif Bahareh , Mohammadi Azar Sirwan , Ebrahimi Bahram
Published: November 2023

Background: Bio-remediation methods of organic pollutants are promising due to their high efficiency, low cost, and green chemistry. These methods are effective alternatives to traditional elimination methods. Methods: Bacillus cereus PTCC 1015S strain was used to eliminate acid blue 113 (AB113) and acid orange 7 (AO7) from aqueous solutions. The bacteria were activated in the Luria Bertani Broth (MILLER) culture medium. The effective parameters such as incubation time and temperature, pH of dye solution, dye concentration, and the bacterial inoculation quantity on decolorization were investigated. Kinetic and thermodynamic studies were done to clarify the different aspects of the introduced method. Also, the reliability of the method to remove studied dyes was investigated in dye factory wastewater samples. Results: The first-order kinetic model was the best model to describe the kinetics of decolorization. The obtained thermodynamic data showed that the elimination process was endothermic (∆H0=+29.03, 30.53) while it was spontaneous (∆G0<0) for both studied dyes and so entropy change (∆S0=+109.63, 116.32) was an effective force in the decolorization. Under optimized conditions, B. cereus PTCC 1015S showed high average removal; 98.5 and 99.3 % for AB113 and AO7 respectively in dye model solutions. The removal efficiency was more than 85 % for both studied dyes in wastewater spiked samples. Conclusions: The B. cereus PTCC 1015 strain was capable of being exploited in the removal of AB113 and AO7 dye molecules as an affordable and eco-amiable method for the treatment of aqueous samples contaminated with the studied azo dyes.

Background: In the petrochemical industries, accidents are generally catastrophic which endanger human, environment and economic. In the industries, there is a wide range of flammable and toxic substances that affect health and safety of workers. They have also adverse effects on society. Numerical risk and impact assessment as well as design for protective layers against catastrophic events are necessary for designing process units. Methods: First, the occupational-process and environmental safety hazards were measured by hazard and operability (HAZOP) and environmental failure mode and effects analysis (EFMEA) techniques. Then, the risk was assessed using the layer and operability analysis (LOPA) method. Results: The results showed that a total of 50 safe and health items and 37 environmental risks were identified by HAZOP and EFMEA methods in Imam Khomeini Petrochemical Aromatic Unit. There were 17, 19 and 14 items with low, medium and high level risk, respectively. Conclusion: This study showed that the LOPA method is more comprehensive than hazard identification methods for the analysis of protective layers. The important actions were blockage of the excess gas to the flare and release the H2S gas. Also, evaluation of the environmental aspects of aromatic unit activities showed that air pollutant production in the power supply unit, waste disposal of reactor tank, waste disposal of condensate tank and reactor fire and explosion were at a high level risk.

Introduction: The leaves of Pluchea indica (L.) Less is empirically used to enhance milk production. This study aimed to evaluate the lactogenic effect of ethanolic extract of P. indica leaves (EPI) on milk production, prolactin, cortisol, oxytocin levels, and histological changes of mammary tissue in lactating rats and weight gain of their pups. Methods: Twenty-five lactating rats with six pups were randomized into five groups. The groups were control (reverse osmosis water), standard (domperidone 2.5 mg/kg BW), and EPI (250, 500, and 750 mg/kg BW). The daily treatments were administered by oral gavage, starting from the second day until day 15 of parturition. Milk production and the weight of the pups were measured daily. Serum prolactin, cortisol, and oxytocin levels in the lactating rats were determined by enzyme immunoassay. Histomorphological alterations of mammary tissues were investigated by hematoxylin and eosin-stained slides. Data were analyzed by one-way ANOVA tests and P<0.05 was considered significant. Results: The daily milk production in groups treated with domperidone and EPI at doses of 500 and 750 was significantly increased compared to the control group (P<0.05). Weight gain of the pups of dams that received domperidone and EPI at doses 500 and 750 mg/kg BW was significantly higher than controls (P<0.05). EPI 500 insignificantly increased both prolactin and oxytocin, insignificantly decreased cortisol levels, and insignificantly enhanced both numbers of alveoli and branching alveoli with milk secretion (P>0.05). Conclusion: Pluchea indica leaves revealed lactogenic activity in lactating rats.

Authors: Kumar Sarath , Sanjeev Kavitha , Sundaramoorthy Nagarathinam , Mahalaxmi Sekar
Published: November 2023

Introduction: Ethylenediaminetetraacetic acid (EDTA), a widely used chelating agent, compromises the bond strength of resin-based sealers when used as a final irrigating solution. Hence, the push-out bond strength of AH Plus, a resin-based sealer, was analyzed when gallic acid, "a chelator" was used as a last irrigating solution. Methods: Forty human single-rooted teeth were accessed and randomly assigned into 4 groups (n = 10): EA (17% EDTA), MA (7% maleic acid), GA (10% gallic acid), and SA (saline). After irrigation, the root canals were coated with AH Plus sealer and obturated using gutta-percha. The root canals were sectioned horizontally into coronal, middle, and apical thirds for evaluating the push-out bond strength. A universal testing machine with a compressive loading of 1 mm/min was employed to test the samples. Results: An increased push-out bond strength was noted with GA in coronal one-third compared to EA and SA but not significant compared to MA (P > 0.05). Similar observations were seen in the middle one-third; however, it was statistically significant compared to all other groups (P < 0.05). Also, the difference between the groups in the apical one-third was not significant. SA showed the lowest push-out bond strength than experimental groups, which was significant in all three sections (P < 0.05). Conclusion: The final rinse of 10% gallic acid increased the push-out bond strength of AH Plus to the root dentin in all thirds of the root canal. Hence, gallic acid 10% might be an effective alternative solution in place of synthetic chelators.

Authors: Alimosazadeh Pedram , Ahmad Khan Mohd Sajjad , Sanei Seyed Javad
Published: November 2023

Introduction: Olive (Olea europaea L.) is one of the important agricultural and medicinal tree species. This study aimed to assess the antifungal efficacy of olive leaf extract (OLE) obtained from different cultivars and during different seasons against Candida albicans strains. Methods: OLE was prepared using four olive cultivars (‘Koroneiki’, ‘Mission’, ‘Rowghani’, and ‘Zard’) obtained in two seasons (spring and autumn) from Golestan province, North of Iran. The phenolic and oleuropein contents of vegetative leaves were measured by colorimetric and HPLC techniques, respectively. The antifungal capacities of OLEs were tested by agar well diffusion and the minimal inhibitory concentration (MIC) was evaluated by micro-dilution assay. Results: The findings of our study showed that the total phenolic (27.45-88.16 mg g-1) and oleuropein (3.64-18.13 mg g-1) contents varied in leaf extracts, respectively. The highest amount was found in ‘Koroneiki’ and ‘Zard’ (spring leaves) and the lowest in ‘Mission’ cultivars (autumn leaves). The inhibition zones and MIC ranged from 1.92 to 15.41 mm and from 6.07 to 27.20 mg mL-1 based on C. albicans strains, respectively. Relationship between total phenolic content as an independent variable (X) and inhibition zones or MIC as dependent variables (Y) fitted polynomial curves. Conclusion: The present study highlighted the phytochemical and anti-candidal efficacy of OLE derived from olive cultivars or the seasons of harvested leaves against C. albicans strains. It is suggested that ‘Koroneiki’ and ‘Zard’ cultivars, especially during the spring season, could be exploited to isolate potential broad-spectrum antifungal drugs.
Review on the use of artificial neural networks to determine the relationship between climate change and the occupancy rates of dams
Authors: Demirbaş Furkan , Elmaslar Özbaş Emine
Published: November 2023

Climate change has the potential to raise temperatures, alter precipitation patterns, and alter how water resources are distributed globally. The occupancy rates of drinking water supplies may change as a result of these changes. For instance, dwindling water supplies may result from rising temperatures and diminishing precipitation. As a result, the occupancy rates of the reservoirs may drop, making it harder to deliver drinking water. Climate change, however, might highlight regional variations and result in wetter conditions in some places. The occupancy rates in the reservoirs could rise in this scenario. Heavy rains, however, can also result in additional issues like infrastructure damage and floods. Climate change-friendly actions must be taken to manage water supplies in a sustainable manner. In the management of water resources, dams are crucial. It has been observed that when a reliable estimate of a dam's flow is provided, data-based models can produce valuable findings for a variety of hydrological applications. It is obvious that one of the most important problems is the difficulty in getting utility and drinking water as a result of climate change and other things. The purpose of this study is to compile the works that can be offered as a result of the literature review on the impact of climate change on surface water resources and dams, given the importance of this topic. As a result of this study, we can deduce a link between the occupancy levels of the reservoirs used to supply drinking water and climate change. Climate change has the capacity to increase temperatures, modify precipitation patterns, and shift the distribution of water supplies. The relationship between climate change and water supplies is better understood thanks to this study.

Published: November 2023

This descriptive-qualitative study aims to discover factors that influence students' difficulties in solving non-routine problems. The researchers employed open-ended questions that had previously been developed by researchers, ensuring that they were valid, practical, and had potential effects. The researchers brought up this topic because non-routine questions can help students improve their mathematical skills. The study's approach consisted of three stages: preparation, implementation, and data analysis. The research subjects were 31 eighth-grade students from one of Belitang's junior high schools. Data was gathered through observation, interviews, and testing. Observation was utilized to collect data on the learning process, while interviews were used to understand more profoundly and directly about students' difficulties in addressing non-routine tasks. The test was then administered to assess students' ability to solve non-routine tasks. The data was evaluated qualitatively using descriptive analysis. Based on observation and interview data, several factors contributed to students' difficulty in solving non-routine problems, including the fact that students had never worked on non-routine problems during the learning process in class, and the teacher's book only contained routine problems. In relation to the foregoing, the exam results show that students' ability to solve non-routine problems remains poor, with as many as 58.07% receiving poor grades, 19.35% receiving moderate grades, and only 22.58% receiving good grades. With this research, it is envisaged that teachers will assign numerous non-routine tasks in class in the future, allowing students' mathematical abilities to be thoroughly developed.

Incorporating an LMS Learning Analytic into Proactive Advising: Validity and Use in a Randomized Experiment
Authors: Rust Matthew Michael , Motz Benjamin
Published: November 2023

This paper presents two studies examining the effectiveness of using learning analytics to inform targeted, proactive advising interventions aimed at improving student success. Study 1 validates a simple learning management system (LMS) learning analytic as predictive of end-of-term outcomes and persistence. Results suggest that this analytic measure, based on students’ activity in the LMS, has predictive utility for identifying students who might benefit from a proactive advising intervention. In Study 2, a randomized experiment with 458 undergraduate pre-major students, we test the hypothesis that an LMS-informed proactive advising intervention would improve end-of-term outcomes and persistence. Students in the treatment group exhibited, on average, an increase of nearly one-third of a grade point in their term GPAs, a reduction in DFWs earned, and an 80% higher likelihood of persisting compared to the control group. These findings provide strong evidence for the effectiveness of proactive advising interventions, where advisors’ efforts are targeted using learning analytics. They suggest that by transparently providing advisors with comprehensible insights, institutions might improve student outcomes and promote the use of data-informed interventions in academic advising.

ABSTRACT Background: The provision of adequate clean drinking water is a basic human need in every society. In Nigeria, like many developing countries, the provision of clean drinking water is not adequate. The introduction of sachet water is seen by many as a solution to the problem. This is because it is affordable where more than a litter of it is sold at ten Naira or even less. The availability and affordability of sachet water have made it a preferred choice for most people despite questions being raised about the purity and potential toxicity. Objectives: To evaluate the heavy metal contents of sachet water in Gombe, Nigeria. Methodology: Forty samples of sachets water were bought randomly from the streets of Gombe and were analyzed for heavy metals content (lead, cadmium, mercury, arsenic and nickel) using Atomic Absorption Spectrophotometer (AAS). The data obtained were analyzed for frequencies and percentages for qualitative data and minimum and maximum for quantitative data using the system for statistical package for the social sciences (SPSS) version 20.00 for windows. Results: None of the sachet water samples had the date of manufacture or expiry date while about 23% had no National agency for food and drug administration and control (NAFDAC) registration numbers. All the samples had lead levels above the WHO safety limits of 0.01mg/L. Mercury, cadmium and arsenic levels were higher than the safety limits in 23%, 15% and 5% of the samples respectively. No nickel was detected in all the samples. Conclusion: The majority of the sachet water in Gombe is contaminated with heavy metals lead, mercury and cadmium in concentrations above the WHO safety limits. Processes of water purification should be put in place to reduce the heavy metal contents of sachet water in Gombe. Keywords: Gombe, heavy metals, sachet water, toxicity

ABSTRACT Background: Pumpkin (Cucurbita spp.), is one of the most popular vegetables consumed in the world, has been recently recognized as a functional food. Traditional crops including the pumpkins, which are rich in micronutrients, are not consumed widely by smallholder farmers in Africa. However, the cultivation of high yielding, nutrient-rich, multipurpose crops-like pumpkin is important in solving the problems of malnutrition and contributing to food security in Africa including Nigeria. Objectives: Therefore, this work aimed at producing Pumpkin pie from Pumpkin puree and wheat supplemented with some indigenous spices alongside butter. Methodology: Formulations into various formed were made using Pearson's method. The formulations were assayed for mineral, vitamin, antinutrient and amino acid composition using standard laboratory methods. A significant (P<0.05) difference was observed in Zn and Ca content of all the samples, with sample D recording the highest value for Zn (1.30±0.01) mg/g and Ca (0.47±0.01) mg/g. However, samples A and D had the least values for Na and Fe. An increasing and decreasing pattern was observed in all the vitamin contents(B1, B2, B6, B12 and C), moving from samples A through to D. Vitamin contents of samples B1 and B6 and higher than the RDA, while B2, B12 and C were below RDA. The overall antinutrient contents observed were generally low, with sample A having the lowest values for Phytate, Oxalate and tannins. The B, C and D are more enhanced in terms of essential amino acids compared to the control group (sample A). Conclusion: Pumpkin pie can be produced from pumpkin and its supplementation of the spices can boost the pie with essential amino acids, minerals, and vitamin composition. This shows the potential of using pumpkin pie as snacks in-between meals for the prevention of Protein Energy Malnutrition (PEM). Keywords: Butter, Cinnamon, Ginger, Pumpkin

Aims and Objectives:1. To determine the relative incidence of benign and malignant gastric outlet obstruction,2. To study the modes of
presentation of gastric outlet obstruction,3. To study the outcome of management of gastric outlet obstruction.Methods:The patients for this study
have been selected from Nellore Medical College, NELLORE from April 2022 to May 2023. In total, 50 in-patients of gastric outlet obstruction
have been studied. Inclusion Criteria:1. Patients presenting with gastric outlet obstruction who are treated on inpatient basis,2. Patients willing for
investigations and treatment. Exclusion Criteria:1. Patients aged 20 years and below,2. Pregnant females,3. Patient with recent history of any
abdominal surgeries. Observations: Out Of 50 cases,1. Gastric outlet obstruction secondary to carcinoma pyloric region – 26, Gastric outlet
obstruction secondary to cicatrized duodenal ulcer – 23, Gastric outlet obstruction secondary to corrosive ingestion – 1. All the patients were
subjected to a standard pre-operative treatment, which included stomach wash twice a day for three days prior to surgery. Conclusion: The
commonest causes of gastric outlet obstruction in adults are carcinoma stomach with antral growth producing gastric outlet obstruction (52%) and
cicatrised duodenal ulcer (46%), In the vast majority of cases, the diagnosis can be established clinically, Upper Gastro intestinal endoscopy should
be mandatory in all suspected cases of gastric outlet obstruction. It can diagnose the cause of obstruction very effectively than any other
investigative modality, Number of cases with cicatrised duodenal ulcer as the chief etiological factor for gastric outlet obstruction is diminishing
and the number of cases of antral carcinoma of stomach as the cause of gastric outlet obstruction is increasing, Effective treatment in carcinoma
stomach depends on early diagnosis
