Potentially Toxic Elements in Urban Dust of Tlaxcala, Mexico: Pollution Levels and Human and Ecological Risk Assessment

The city of Tlaxcala, located in central Mexico, is a small region with high industrial activity that releases potentially toxic elements (PTEs) into the environment. This study investigated the concentration, distribution, contamination levels, and human and ecological health ri...

N-Nitrosodiethanolamine Degradation in Water by Ag/TiO2 and Ag/SiO2 Under Natural Solar Light

On 304 stainless steel substrates, two combined systems based on silver particle semiconductors, Ag/TiO2 and Ag/SiO2, were formed. Such systems were applied in the photocatalytic degradation, profiting from sunlight, of nitrosamines, which are highly toxic substances, specificall...

Cleft Palate Surgery: Evolving Surgical Techniques and Reconstructive Principles for Oronasal Fistula and Velopharyngeal Dysfunction: A Narrative Review

Background Despite more than a century of surgical innovation, no single palatoplasty technique has demonstrated consistently superior outcomes across the spectrum of cleft palate phenotypes. Objective This review examines the historical evolution of cleft palate reconstruction a...

Recent Advances in Printing of SERS Substrates

Abstract Detection of trace chemicals, heavy metals, biomolecules, explosives, and threats such as nerve agents and narcotics is a challenging task. The selection criteria for candidate technology include sensitive detection capability with ultra-low limits of detection, unambigu...

2,4-Dichlorophenol Photodegradation by Novel Burtite-like Solid Solutions: Effect of Sn4 + and Al3 + Content on the Physicochemical Properties and Photocatalytic Performance

Abstract Nowadays, tailoring the physicochemical properties of novel photocatalysts is crucial for advanced environmental remediation technologies. Thus, in this work, novel solid solutions of burtite-like compounds with nominal Sn amounts of 5.3–27.8 mol % were synthesized. Mate...

Antifungal activity of Burkholderia sensu lato metabolites against coffee phytopathogens: evidence of chemical diversity

Abstract The environmental and health concerns associated with the widespread use of synthetic pesticides have intensified the search for sustainable alternatives to control phytopathogenic fungi. In this context, members of the Burkholderia sensu lato group have been recognized...

Block method: Reference-anchored peak fitting for tracking subtle chemical evolution in sequential XPS spectra

The Block Method is a refinement of spectral subtraction developed for the analysis of complex x-ray photoelectron spectroscopy data. In this method, the fitted spectrum of a reference sample is converted into a structured spectral block and used as an additional component during...

Measurements of the production of W$$^{\pm }$$ and Z$$^0$$ bosons in pp collisions at $$\sqrt{s} = 13$$ TeV

Abstract Measurements of the production of the W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons at midrapidity in pp collisions at $$\sqrt{s} = 13$$ s = 13 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons are detected via their (di)e...

ZnO/p-Si heterostructure for UV sensing and long-range IoT environmental monitoring

The development of low-cost photoconductive ultraviolet sensors with long-range wireless communication remains an attractive approach for environmental monitoring applications. In this work, a ZnO/p-Si photoconductive heterostructure was fabricated by spray pyrolysis and experime...

Study in silico and experimental of a double-pass Mach–Zehnder interferometer sensor for acetone detection as a biomarker of diabetes mellitus

Acetone detection through breath analysis has gained relevance, as it is a biomarker of diabetes mellitus, with optical fiber sensors being a promising alternative for constructing compact, inexpensive, and rapid measurement devices. Furthermore, the design of an in silico optica...

Oncoplastic Reconstruction of the Anterior Chest Wall Using a Latissimus Dorsi Myocutaneous Flap: A Case Report

Background: Dermatofibrosarcoma protuberans (DFSP) is an uncommon cutaneous fibroblastic neoplasm characterized by infiltrative growth, low metastatic potential, and a high risk of local recurrence following incomplete excision. Large or recurrent tumors of the anterior chest wal...

Differences related to sex in adolescent obese Zucker rats: locomotor activity and dendritic arborization of neurons in layer V of the primary motor cortex

Obesity is a metabolic disorder characterized by the accumulation of excess body fat, which has been linked to skeletal muscle and motor behavior changes. Despite the high prevalence of obesity among children and adolescents in Mexico, it has mostly been studied using adult obese...

APOS-SRR approach: a result of the networking of theories between APOS Theory and semiotic representation registers

Abstract The objective of this research was to formally articulate Action, Process, Object, and Schema (APOS) Theory and Semiotic Representation Registers (SRR) Theory through the Networking of Theories methodology. As a result, we propose an approach denominated APOS-SRR, an exp...

Interactive Playback Visualizer to Analyze Joint-Angle Co-Modulation with a Wavelet Approach: Application to Pose-Voice Relationships During Spontaneous Conversation

Deep visual recognition can turn ordinary video into interpretable motor knowledge, yet coordination among the joints of a single body during social interaction remains largely unexplored. We present an interactive playback visualizer that couples markerless pose estimation with...

Early-life overconsumption of a high-carbohydrate diet induces metaflammation and kidney injury without impairment of function in adult Wistar rats

Abstract Frequent consumption of sugary and calorie-dense foods and beverages during childhood may contribute to the development of metabolic syndrome (MetS) in adulthood, a risk that can manifest independently of overweight status. Metaflammation, a low-grade inflammation associ...

Pinoresinol as a Potential c-Myc Complex Modulator: An In Silico Study

The c-Myc oncoprotein is a central regulator of oncogenic transcriptional programs that remains challenging to inhibit directly, necessitating strategies that target c-Myc–associated protein complexes rather than the protein alone. This study conducted an in silico evaluation of...

From Structural Inequalities to Labor Precarity: Adoption of Digital and AI Tools in Latin American Journalism
