“…Considering the highly skewed distribution of redox markers and contaminants, the magnitude of the associations was analyzed by means of robust regression based on the MM-estimator. 49 The covariates included were initially selected from among those most commonly used in the available literature. 19,50,51 Final covariate selection in the multivariable models was performed by using a combination of forward and backward stepwise methods.…”

The relationship between phthalates, a group of chemical pollutants classified as endocrine disruptors, and oxidative stress is not fully understood. The aim of the present hospital-based study was to explore the associations between circulating levels of 10 phthalate metabolites and 8 biomarkers of oxidative stress in adipose tissue. The study population (n = 143) was recruited in two hospitals in the province of Granada (Spain). Phthalate metabolite concentrations were analyzed by isotope diluted online-TurboFlow-LC−MS/MS in serum samples, while oxidative stress markers were measured by commercially available kits in adipose tissue collected during routine surgery. Statistical analyses were performed by MM estimators' robust linear regression and weighted quantile sum regression. Mainly, positive associations were observed of monomethyl phthalate (MMP), monoiso-butyl phthalate (MiBP), and mono-n-butyl phthalate (MnBP) (all low molecular weight phthalates) with glutathione peroxidase (GPx) and thiobarbituric acid reactive substances (TBARS), while an inverse association was found between monoiso-nonyl phthalate (MiNP) (high molecular weight phthalate) and the same biomarkers. WQS analyses showed significant effects of the phthalate mixture on GSH (β = −30.089; p-value = 0.025) and GSSG levels (β = −19.591; p-value = 0.030). Despite the limitations inherent to the cross-sectional design, our novel study underlines the potential influence of phthalate exposure on redox homeostasis, which warrants confirmation in further research.

Interdisciplinarity encourages students to make connections between different academic disciplines, fostering a deeper understanding of complex real-world problems. By integrating various subjects, students are able to develop critical thinking skills and apply their knowledge in practical ways. This approach not only enhances their learning experience but also prepares them for the challenges they may face in their future careers. In the paper, a strong connection between mathematics and mechanics has been demonstrated. It is important to note that the discussion of this topic is just scratching the surface of the many aspects that can be explored. This example highlights the principle of continuous learning and the endless possibilities for acquiring new knowledge in any field. The process of knowledge is infinite and always open to new contributions. By integrating knowledge from different disciplines, individuals can gain a holistic understanding of complex concepts and phenomena. This interdisciplinary approach fosters critical thinking skills and encourages creative problem-solving, enabling learners to tackle real-world challenges with a broader perspective. Additionally, the collaboration between disciplines promotes innovation and encourages the development of new ideas and solutions. This paper presents aspects regarding the application of the collinearity property in mechanics. The laws of motion of a rigid body, scalar functions of time are meant, which determine, in any moment of the motion, the position of the body in relation to a benchmark through the examples taken in the study were taken from point kinematics and rigid kinematics, also studying how the velocity and acceleration of the points of the solid body vary, in relation to the same reference system.
