title: The Effect of Supplementing Tea Polyphenols on Yolk Cholesterol and Production Performance of Laying Hens During the Egg-laying Period

description: ABSTRACT This study aimed to investigate the effect of supplementing 300 mg/kg tea polyphenols (TP) on yolk cholesterol content and production performance of laying hens during the egg-laying period. A total of 600 Roman laying hens aged 24 weeks were randomly divided into two dietary treatment groups. The feeding experiment lasted for 48 weeks. Layers fed basal diet supplemented with 0 (control group) and 300mg/kg TP (TP group) diet, respectively. The yolk cholesterol content, laying performance, and egg quality were determined at 28, 38, 48, 58, and 68 weeks of age. The yolk cholesterol content in the TP group was significantly decreased at 28-68 weeks of age (p&lt;0.01), compared to the control group. There was a significant increase in laying rate in the TP group at 38 weeks of age (p&lt;0.05), compared to the control group, while no significant differences during the other laying periods were obtained (p&gt;0.05). The FCR significantly decreased in the TP group at 38 weeks of age whereas AEW significantly increased in the TP group at 58 weeks of age (p&lt;0.05). Similarly, the eggshell thickness and eggshell strength in the TP group significantly increased (p&lt;0.05), compared with the control group at 38 weeks of age. The albumen height and Haugh unit significantly increased at 28 weeks of age (p&lt;0.05). In conclusion, the results showed that the diet supplemented with 300 mg/kg TP had positive effects on production performance of layers during the egg-laying period, and could lessen yolk cholesterol content significantly at 28-68 weeks of age.

title: Continuous or interval aerobic exercise training reduces daily fructose intake in female Wistar rat

description: ABSTRACT: Objctive: Fructose consumption has increased worldwide. Excessive fructose intake has been a risk factor for the increased metabolic syndrome disorder incidence. This study aimed to investigate the possible influence of two different exercise training methods, continuous and interval, on fructose intake. Methods: Thirty two-months-old female Wistar rats were divided into six groups: sedentary + water ; sedentary + fructose ; continuous training + water ; interval training + water ; continuous training + fructose ; interval training + fructose . Fructose was given in drinking water (10%). Continuous (40 minutes at 40% maximal speed) or interval training (28 minutes, 1 minute at 70%; 3 minutes at 35% maximal speed) sessions were carried out 3 days/week for 8 weeks. Results: Fructose consumption decreased food intake with a concomitant increase in fluid intake. Continuous and interval training did not modify food intake but progressively reduced fructose ingestion. In the 8th week, interval training + fructose and continuous training + fructose groups drank less fructose solution, 35% and 23%, respectively, than sedentary + fructose group. Conclusion: The findings indicate that both continuous and interval aerobic exercise training seem to modulate food behavior, possibly by mitigating the craving for sweetness, with interval training being more effective in reducing fructose intake than continuous exercise.

title: THE STRATEGIC FIT’S EFFECTIVENESS IN THE COMPETITIVE MARKET: FOCUS ON SMALL BUSINESSES IN AN EMERGING COUNTRY

description: ABSTRACT This study analyzes how small businesses in an emerging country improve performance through strategic fit according to the intensity of market competition. It explores small businesses’ prospector or defender strategies in an environment of intense market competition. Data were collected from 107 small businesses in Vietnam, and PLS-SEM was used to assess the research model. The results showed that only prospector businesses improve performance in intense market competition. This study contributes to the literature fourfold. First, it extends the current knowledge of strategic fit by addressing the mediating effects of strategic behavior. Second, it contributes to the growing literature on contingency theory in small businesses’ strategic management. Third, this research offers a deeper understanding of the unique characteristics of emerging countries that jeopardize the effectiveness of using a defender strategy. Fourth, this study overcomes limitations observed in the literature regarding using single-item constructs to operationalize strategy variables.

title: Food insecurity and financial aid among university students: Pre-Covid-19 scenario of a public university in southeastern Brazil

description: ABSTRACT: Objective: To estimate the prevalence of food insecurity among beneficiary and non-beneficiary university students of financial aid and associated factors. Methods: A cross-sectional study, with a probabilistic sample of 100 university students, was conducted at a federal university located on the coastal city of São Paulo in southeastern Brazil. The data made it possible to address sociodemographic aspects, food security and food quality markers. Data analysis involved descriptive statistics, Fisher’s exact association test and Mann-Whitney comparisons of means were used to investigate the prevalence of food insecurity between groups and associations with covariables at 5%. Results: The results revealed significant differences between groups. Receiving financial aid was associated with more vulnerability to facing food insecurity: 94% have some level of food insecurity (p=0.001); non-white skin color (p=0.019); overseeing one’s own income (p=0.001); the amount of money available to stay at the university (p=0.030). According to food quality markers, both groups often consumed ultra-processed foods (unhealthy quality marker). In contrast, most (92.3%) were concerned with consuming healthy foods. Conclusion: The pre-Covid-19 scenario reveals that despite receiving financial aid, a large part of students faced food insecurity in the three months prior to the study. Therefore, food insecurity should be recognized as a public health concern among university students, and adequate resources should be made available to avoid the occurrence of dropouts and assist in breaking the intergenerational cycle of social exclusion and the human right to food.

title: SOIL PHOSPHORUS TEST USING A LOW-COST SPECTROPHOTOMETER AND MACHINE LEARNING

description: ABSTRACT Phosphorus concentration is one of the main attributes determined in laboratory analyses of soil samples collected in the field. The objective is to develop a soil phosphorus test using a low-cost spectrophotometer and a machine learning technique. For reflectance measurements, a low-cost system consisting of a Sparkfun AS7625x spectrophotometer and an Arduino Uno is used. Ion exchange resins under standard saturated solutions and modified conditions are used to extract phosphorus ions from the soil samples. Reflectance and phosphorus concentrations determined by the reference method are used in the training and testing of a machine learning. A modification procedure of the ion-exchange resin saturation solution allows the establishment of a strong correlation between the reflectance in 18 spectral bands and P concentration of the soil samples. The obtained model uses five reflectance of the modified resins at wavelengths of 410, 460, 560, 705, and 645 nm to predict the phosphorus concentration. This model presents an R2t accuracy of 0.97 in the training stage with an R2v of 0.96, RMSEv of 9.05, and ratio of prediction to deviation) of 3.81 in the test step.

title: Morpho-agronomic and leaf anatomical traits in Coffeacanephora genotypes

description: ABSTRACT: Genetic variability is the basis for coffee genetic breeding. This study evaluated the potential of leaf anatomy and morpho-agronomic traits in studies of genetic variability in C. canephoracultivars. Ten genotypes were distributed in randomized block designs with three replicates. Significant differences among genotypes were detected by F-test (P &lt; 0.05) for 13 of 15 evaluated traits. These results evidenced the heterogeneity of the studied cultivars, which is essential in composition of genetic basis in breeding programs. The Scott-Knott test detected variability among genotypes, grouped into up to four mean groups. Leaf anatomy traits presented the largest variations. Five out of seven leaf anatomy traits presented heritability higher than 80%, with emphasis on stomatal density (95.69%) and stomatal pore length (92.72%). Positive correlations were observed among morpho-agronomic and anatomic traits. Cluster analysis used the Mahalanobis general distance (D2) as a measure of genetic dissimilarity and divided the genotypes into two distinct groups. The inclusion of leaf anatomic traits to characterize C. canephoragenotypes may assist plant breeders with better genetic discrimination and with greater security in plant selection when composing cultivars.

title: SEED EMERGENCE AND DEVELOPMENT OF Caesalpinia pulcherrima L. SW. AND Cassia grandis L. F. IN ORGANIC SUBSTRATES

description: ABSTRACT The addition of adequate proportions of organic residues to formulate substrates with soil, render positive results on germination and seedling growth by providing benefits to the physical and chemical attributes of the soil. Determining an adequate proportion of such residues is essential to obtain seedlings exhibiting morphophysiological quality. This study aims to evaluate seed emergence and the development of Caesalpinia pulcherrima (L.) Swartz and Cassia grandis L. f. seedlings in organic substrates. The experiment was set in a completely randomized design arranged in 2 x 3 x 5 factorial scheme, consisting of two soil classes (Oxisol and Entisol), three types of organic substrate (COP (organic compost from tree pruning + cattle and goat manure), CLU (urban waste compost), RES (residue from the extraction of sisal fiber) and five percentages of organic residues (0, 20, 40, 60, 80). The percentage of emergence and emergence speed of seeds, plant height, number of leaves, root length and dry mass were determined. The species showed better results for these variables when adding organic residues to the substrate. The addition of 80% COP or CLU to the substrate provided higher mean values for percentage of emergence in seeds of Caesalpinia pulcherrima, and the substrate constituted by only soil provided higher dry mass in seedlings of this species. The combination of 50% COP and 50% soil (Oxisol and Entisol) resulted in higher means for the percentage of seed emergence, velocity of emergence and biomass production in Cassia grandis L. f. seedlings.
