The present study aimed to determine the factors associated with the level of knowledge about antimicrobials and antimicrobial resistance among physicians in the city of Iquitos, in 2025. It was an observational, analytical, cross-sectional study with a relational and epidemiological (field) design. A total of 140 physicians from public and private health institutions in Iquitos were included during 2025. Data were collected through a survey, and the instrument used was a validated questionnaire. SPSS version 27.0 was employed for the analysis. Informed consent was obtained from all participants, ensuring anonymity of the information, and bioethical principles were applied. Seventy-five percent of participants showed an adequate level of knowledge about antimicrobials and antimicrobial resistance. Sociodemographic and training-related factors revealed that most were adults between 30 and 59 years old (74,3%), had 1 to 10 years of work experience (51,4%), held a medical specialty (55,0%), and worked in MINSA hospitals (55,0%). Likewise, the majority worked in a single institution (67,9%), had completed undergraduate studies at public universities (82,1%), pursued postgraduate studies at public universities (51,4%), and had not received specialized courses in antimicrobials (55,0%). A statistically significant association was identified between age group (p=0,031), work experience (p=0,029), specialty (p=0,049), and the level of knowledge about antimicrobials and antimicrobial resistance. The study concluded that physicians demonstrated adequate knowledge of antimicrobials and antimicrobial resistance.

The central purpose of the present study was to determine the association existing between cooperative work and academic achievement in the subject of Communication, specifically among fifth-cycle primary education students at Educational Institution N° 61014 “Horacio Zevallos Gámez” in Iquitos, during the 2024 academic year. The research was based on a non-experimental design approach, with a nature that progressed from descriptive to correlational. The sample population consisted of 101 students. For data collection, a questionnaire was used, whose reliability and relevance were ensured through expert judgment for its validation. The inferential data analysis yielded a Spearman's Rho correlation coefficient of 0.452, accompanied by a significance level of p=0.000. These findings allow for the conclusion and demonstration that the variables cooperative work and learning achievements in the area of Communication, in the previously cited group of students, maintain a statistically significant and positive relationship.

The research was carried out in the Loreto Region in a terrain with textural characteristics of clay loam, of low fertility, with medium content of organic matter whose purpose was to analyze the effects on Leaf Mustard (Brassica juncea L.) of 3 types of organic years: Poultry Manure (T4), Compost of Household Organic Solid Waste (T3), Compost of Compound Organic Matter (T2) and a control treatment without application of Organic Fertilizer (T1). Statistical design was used to study the results. of the BCA, Tukey's Test that led to important conclusions: Manure (T4) turned out to be the most effective organic fertilizer than the other organic fertilizers, promoting greater vegetative development and yield as can be seen in the results of 900 g per plant and 45,000 Kg/ha and an economic utility of S/.20,428.00.

The objective of the research was to study the behavior in agronomic characteristics and yield components among nine corn genotypes (6 varieties and three hybrids). Due to its approach, it was quantitative, prospective, explanatory level and experimental research design. The target population was 2,304 corn plants, distributed at a rate of 64 plants / genotype from which samples of 28 plants were taken for each genotype, making a total of 1,008 hard yellow corn plants belonging to the El Porvenir experimental station in Tarapoto. The experimental design was a Randomized Complete Block Design (DBCA) with four replications. The data obtained were analyzed through the R software and its graphical interface R Studio version 4.4.1. Graphical tests of homogeneity of variances, normality, independence and additivity were performed. Among the main conclusions obtained were that the hybrids of yellow hard corn, particularly Hybrid 1 and Hta4, demonstrated significant statistical superiority in grain yield. Although some varieties such as Marginal 28T and Nutrimaiz showed competitive values in specific morphological components (length and diameter of cob), this did not translate into higher grain yields, confirming that the final yield is more influenced by the joint effect of multiple components than by characteristics, recommending to prioritize the sowing of Hybrid 1 and Hta4 when the main objective is to maximize grain yield per hectare, but which must also consider economic aspects such as the cost of hybrid seed versus variety seed, as well as the possibility of reusing seeds in the case of varieties.

Objective: To quantify the phenolic compound content and evaluate the antioxidant potential in extracts from the leaves and bark of Prunus rotunda. Methodology: Total phenols, flavonoids, anthocyanins, and catechins in the leaf and bark extracts of P. rotunda were quantified using UV-Visible spectroscopy. Antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, calculating the inhibition percentage at concentrations of 1, 10, and 15 mg/mL. Results: The bark exhibited higher concentrations of total phenols (19118.74 mg/100g), flavonoids (35.596 mg/100g), and anthocyanins (24.604 mg/100g) compared to the leaves (13153.05 mg/100g, 25.680 mg/100g, and 19.819 mg/100g, respectively). However, the leaves showed a slightly higher content of catechins (0.073 mg/100g vs. 0.066 mg/100g in the bark). In terms of antioxidant activity, the bark displayed a higher inhibition percentage at lower concentrations, achieving an IC50=0.54 mg/mL, while the leaves only reached comparable inhibition levels at higher concentrations, with an IC50=8.17 mg/mL. Conclusion: The bark of P. rotunda stands out as a rich source of phenolic compounds with remarkable antioxidant activity.
