This research aims to find out the mistakes made by students and the factors that cause mistakes made by students in solving algebraic form problems in terms of Polya steps. This type of research is descriptive and qualitative. The sample used was 28 students with the sampling technique used being proportionate stratified random sampling. Data collection techniques are carried out by tests and interviews. Based on the analysis of student test results, error were obtained by students in each question item, namely, errors in understanding the problem, errors in drawing up plans, errors in implementing plan, and errors in re-examining. The results showed that the percentage of mistakes made by students in the whole question was 44% errors in understanding the problem with sufficient categories, 36% errors in drafting plans with low categories, errors in implementing plan by 33% with low categories, and errors in re-examining by 61% with high category. The cause of students' mistakes in solving algebraic form questions is that students are not careful in reading the questions and in writing down their work, do not understand the questions or prerequisite materials, both the nature, formulas, or procedures for working on the questions, the desire to answer briefly to things that are known and asked. As well as students are not used to re-examining.

The importance of the measles immunization vaccine for children up to the age of 9 months to prevent children from getting sick with measles or reduce the transmission rate in the surrounding environment, especially at the Gambir Health Center. This demand is still considered ineffective and there is often an oversupply of vaccines, which results in a buildup of vaccines in storage. The purpose of this study was to create a measles vaccine needs forecasting system using the Single Exponential Smoothing (SES) method. The model used to build this system is the Systems Development Life Cycle (SDLC) with stages of analysis, design, implementation, and trial. Data collection techniques use observation, interviews, or smart phones for shooting or sound recording. The analysis technique for system forecasting uses the SES method, while the system testing uses a Blackbox. Our findings show that the lowest MAPE value was obtained at 49.8%. The results of testing the system using a Blackbox that all components in this system are already functioning properly. With this system, it can make it easier for related parties to predict the number of measles vaccines in the new Gambir health center.

Published: December 2022

Diabetes mellitus, describes a group of metabolic diseases in which the person has high blood glucose (blood sugar), either because insulin production is inadequate, or because the body’s cells do not respond properly to insulin, or both. Patients with high blood sugar will typically experience polyuria (frequent urination), they will become increasingly thirsty (polydipsia) and hungry (polyphagia). The population of bacteria and microbes that live in our gut is called the gut microbiome. which are divided into two categories of useful (non-pathogenic) and harmful (pathogenic) bacteria. Disease occurs when the ratio of harmful to beneficial bacteria increases. It is known that these microbes play a role in various systems in the human body, including the immune system, allergies, inflammation in the body, and cancer. Escherichia coli bacteria (E. coli) is the most studied bacteria in the world. E coli, is a rod-shaped gram-negative bacterium that is commonly found in the lower intestine of warm-blooded animals. E. coli is also found in birds, fish and reptiles
Possible protective effects of two different doses of cyanocobalamin against methotrexate nephrotoxicity in rats
Authors: Alduboni Noor Mohammed , N Al-Shawi Nada 
Published: December 2022

Abstract
Nephrotoxicity is defined as rapid deterioration in kidney functions. It arises from direct exposure to drugs or their metabolites. Methotrexate is a famous chemotherapeutic drug with anti-inflammatory and immunosuppressive properties. A high-dose methotrexate-induced renal dysfunction can be life threatening. Cyanocobalamin, one of the forms of vitamin B12, acts as a coenzyme in the conversion of homocysteine to methionine in the cytosol, and the conversion of methylmalonyl-CoA to succinyl-CoA in the mitochondrion. This study is designed to examine the effect of cyanocobalamin in two different doses each co-administered with methotrexate at 20 mg/kg induced nephrotoxicity in rats through the involvement of Nrf2/keap1 molecular mechanism in this respect. Rats utilized in this study were randomized into 4 groups (ten rats per each group); Group 1- (Control) rats intraperitoneally injected with 0.5ml normal saline once daily for 7 consecutive days. Group 2- Rats intraperitoneally injected with 0.5ml normal saline once daily for 7 consecutive days; and at day 2, a single intraperitoneal dose of methotrexate (20mg/kg) is to be injected. Group 3- Rats intraperitoneally injected with a 0.5mg/kg cyanocobalamin once daily for 7 consecutive days, and at day 2, a single intraperitoneal dose of methotrexate (20mg/kg). Group 4- Rats intraperitoneally injected with a 2mg/kg cyanocobalamin once daily for 7 consecutive days, and at day 2, a single intraperitoneal dose of methotrexate (20mg/kg). Co-administration of cyanocobalamin at doses cyanocobalamin 0.5mg/kg and 2mg/kg with methotrexate showed significant reduction (P<0.05) in malondialdehyde, significant elevation (P<0.05) in reduced glutathione level, significant upregulation in renal Nrf2 expression and significant down regulation in renal keap1 expression each compared to corresponding levels in methotrexate-only treated group. In conclusion this study demonstrated that co-administration of cyanocobalamin at two different doses with MTX resulted in attenuation of its nephrotoxicity by the utilization of selected parameters.
Keywords: Nephrotoxicity, methotrexate, cyanocobalamin, malondialdehyde, glutathione, Nrf2, Keap1.

Published: December 2022

Since its first description as a cytotoxic agent, Olea europaea leaves extract gained significant popularity against human breast cancer, ethyl acetate extract of Olea europaea leaves obtained by acid hydrolysis method was evaluated in vitro as cytotoxic agent against new human breast cancer (AMJ13) cell line, using the MTT assay. One main pentacyclic triterpenoid; oleanolic acid, was isolated from leaves of Olea europaea by well-known two different methods, but not used for this compound before, the acidic hydrolysis method and basic acidic method. The presence of oleanolic acid was proved in both methods with qualitative and quantitative determination using high performance liquid chromatography (HPLC), which was active against breast cancer AMJ13 cell line with IC50 value of 0.8936 ?g/ml.
