    El campo de la arquitectura incluye diferentes aspectos que la afectan, entre ellos, los factores que contribuyen a la percepción sensorial de los espacios arquitectónicos. Entre estos factores podemos encontrar la luz, el calor, el olor y el sonido. En cuanto al sonido los arquitectos y los diseñadores no han puesto mucho énfasis en su presencia como factor determinante del diseño de los espacios arquitectónicos. En la UAM-A se ha desarrollado un laboratorio enfocado a estudiar el sonido en el ámbito de la arquitectura, el urbanismo y el diseño, y este laboratorio es el Laboratorio de Análisis y Diseño Acústico (LADAc) de la División de Ciencias y Artes para el Diseño. Este artículo describe el trabajo de investigación que este laboratorio está desarrollando para lograr una relación significativa entre el sonido y la arquitectura

    Uno de los ejes curriculares del plan de estudios de la licenciatura en Arquitectura de la Universidad Autónoma Metropolitana unidad Azcapotzalco (UAM-A) es el correspondiente al de Expresión Arquitectónica. Actualmente cuenta con 5 unidades de enseñanza aprendizaje (UEA) como apoyo al mejoramiento de capacidades en la expresión gráfica de ideas y conceptos arquitectónicos. Al inicio de la línea, en una etapa de aprendizaje, desarrollo de conocimientos y habilidades, el alumno debe experimentar el dibujo a mano alzada a través del empleo de diversos medios, sustratos y técnicas, continuando con el manejo de instrumentos de dibujo y posteriormente enfrentarse al uso de herramientas digitales que lo ayuden a profundizar en los conocimientos y habilidades adquiridas. Este trabajo refuerza la importancia del lenguaje gráfico arquitectónico, además de mostrar el proceso de transición hacia la enseñanza-aprendizaje mediada por tecnologías digitales en el marco del Programa Emergente de Enseñanza Remota (PEER), implementado por la UAM-A durante el trimestre 20-I. El PEER (2020) se ideó como un proyecto en apoyo a los estudiantes y profesores durante el proceso de enseñanza-aprendizaje a partir del empleo de recursos tecnológicos a distancia en respuesta a la emergencia sanitaria suscitada. A fin de evidenciar el aprendizaje adquirido a lo largo de la realización de cada una de las prácticas y ejercicios propuestos, se solicitó la realización de un ejercicio diagnóstico al iniciar el curso, mismo que tendrían que repetir después de 9 semanas, pero ahora aplicando los conocimientos y habilidades adquiridas a lo largo del curso

    Worldwide, canine mammary cancer (CMC) is the most frequent type of neoplasia in female dogs, and it is three times more frequent in dogs than in humans. In Colombia, CMC is the second most frequent type of cancer, after skin neoplasia. Genetics is one of the most important factors involved in any type of cancer, and the genetic basis of this disease is reflected through line breeding due to changes in allelic frequencies that are traceable using molecular markers. This study aimed to detect single nucleotide polymorphisms (SNPs) associated with CMC in blood samples collected from collected from healthy and CMC female dogs at Diego Villegas Toro Veterinary Hospital of Universidad de Caldas (Manizales, Colombia). We designed primers using Primer-BLAST and Primer3, and gene fragments from HER2, MUC1, ESR1, and BRCA1 were amplified to identify SNPs through genome mapping using the UCSC Genome Institute genome browser. We used the genome of Canis lupus familaris Boxer breed [GCF_000002285.3, (CanFam 3.1)] as a reference to compare the gene fragments and SNPs. We associated SNPs with the CMC and control groups by testing odds ratios (OR) through Fisher’s exact tests to determine an association or risk for CMC. We detected two SNPs for ESR1, three for MUC1, six for HER2, and one for BRCA1. MUC1 was the only gene to display an SNP in an exonic region that resulted in an amino acid substitution (Pro>Thr). No significant differences based on the OR were found, though the majority of SNPs, with the exception of four, were found in females with CMC. We report a novel molecular marker for HER2 that amplifies exons 25–26 and introns 24-25, and highlight the importance of conducting further studies on MUC1 and elucidating the role of introns and splicing in candidate genes associated with CMC.Diljem svijeta, tumor mliječne žlijezde kuja (CMC) najčešća je skupina neoplazija kuja te je tri puta učestalija u pasa nego u ljudi. U Kolumbiji, CMC je bio druga najčešća vrsta tumora, nakon neoplazija na koži. Nadalje, genetika je jedan od najvažnijih čimbenika uključenih u bilo koju vrstu tumora, a genetska baza ove bolesti održava se kroz linijski uzgoj uslijed promjena alelnih frekvencija, koje se mogu pratiti preko molekularnih markera. Ova studija imala je za cilj detektirati polimorfizme jednog nukleotida (SNP-e) povezane s CMC-om u uzorcima krvi prikupljenih od kuja s CMC-om i zdravih kuja u veterinarskoj bolnici Diego Villegas Toro Sveučilišta Caldas (Manizales, Kolumbija). Dizajnirali smo početnice uporabom Primer-BLAST i Primer3 te su fragmenti gena HER2, MUC1, ESR1 i BRCA1 pojačani za identifikaciju SNP-a preko mapiranja genoma uporabom preglednika genoma Instituta za genom Sveučilišta Santa Cruz u Kaliforniji (UCSC). Rabili smo genom Canis lupus familaris pasmine bokser [GCF_000002285.3, (CanFam 3.1)] kao referencu za usporedbu fragmenata gena i SNP-a. Povezali smo SNP-e s CMC-om i kontrolnim skupinama testiranjem omjera izgleda (OR) pomoću Fisherovih egzaktnih testova za određivanje povezanosti ili rizika od CMC-a. Detektirali smo dva SNP-a za ESR1, tri za MUC1, šest za HER2 i jedan za BRCA1. MUC1 je bio jedini gen koji je pokazao SNP u regiji egzona što je rezultiralo supstitucijom aminokiseline (Pro>Thr). Nismo pronašli značajne razlike na temelju OR-a, premda je većina SNP-a, izuzev četiri, pronađena u kuja s CMC-om. Prijavljujemo novi molekularni marker za HER2 koji pojačava egzone 25 - 26 i introne 24 - 25 te naglašavamo važnost provođenja dodatnih studija na MUC1, kao i pojašnjenja uloge introna i izrezivanja u gena kandidata poveznih s CMC-om

    Childhood and adolescent cancer survivors (CACS) are a high-risk population for non-communicable diseases and secondary carcinogenesis. The Environmental and Community Health Program for Longitudinal Follow-up of CACS in the region of Murcia, Spain, is an ongoing pioneering program that constitutes a model for social innovation. This study aims to present the program tools and protocol as a whole, as well as a profile of the incidence, survival, and spatiotemporal distribution of childhood cancer in the region of Murcia, Spain, using 822 sample cases of cancer diagnosed in children under 15 years of age (1998-2020). While the crude incidence rate across that entire period was 149.6 per 1 million, there was an increase over that time in the incidence. The areas with a higher standardized incidence ratio have shifted from the northwest (1998-2003) to the southeast (2016-2020) region. Overall, the ten-year survival rate for all tumor types was 80.1% over the entire period, increasing the five-year survival rate from 76.1 (1998-2003) to 85.5 (2014-2018). CACS living in areas with very poor outdoor air quality had lower survival rates. Furthermore, integrating environmental health into clinical practice could improve knowledge of the etiology and prognosis, as well as the outcomes of CACS. Finally, monitoring individual carbon footprints and creating healthier lifestyles, alongside healthier environments for CACS, could promote wellbeing, environmental awareness, and empowerment in order to attain Sustainable Development Goals for non-communicable diseases in this population.This research was supported by the Environment, Survival and Childhood Cancer Project, Spanish Federation of Parents of Children with Cancer (FFIS-CCE-2019-11); Environmental Health Profile for Children Project funded by Sociedad Pediatria Sureste Esp.

    Fibromyalgia has a significant impact on the lives of patients; symptoms are influenced by psychological factors, such as psychological flexibility and catastrophizing. The objective of this study was to determine the importance of these variables in moderating the association between the severity and impact of fibromyalgia symptoms. A total of 187 patients from a general hospital population were evaluated using the Combined Index of Severity of Fibromyalgia (ICAF), the Fibromyalgia Impact Questionnaire (FIQ), the Acceptance and Action Questionnaire-II (AAQ-II), and the Pain Catastrophizing Scale (PCS). A series of multiple regression analyses were carried out using the PROCESS macro and decision tree analysis. The results show that psychological flexibility modulates the relation between severity and the impact of fibromyalgia symptoms. Catastrophism has residual importance and depends on the interaction with psychological flexibility. Interaction occurs if the severity of the disease is in transition from a mild to a moderate level and accounts for 40.1% of the variance in the sample. These aspects should be considered for evaluation and early intervention in fibromyalgia patients
