Multiple approaches to understanding the taxonomic status of an enigmatic new scorpion species of the genus Tityus (Buthidae) from the biogeographic island of Paraje Tres Cerros (Argentina)

Andres Alejandro Ojanguren Affilastro (2017, [Artículo])

Tityus curupi n. sp., belonging to the bolivianus complex, is described from the biogeographically distinct area of Paraje Tres Cerros in north-eastern Argentina. We also present a molecular species delimitation analysis between Tityus curupi n. sp. and its sister species Tityus uruguayensis Borelli 1901 to confirm species integrity. Furthermore, a cytogenetic analysis is presented for these two species which contain different multivalent associations in meiosis, as a consequence of chromosome rearrangements, and the highest chromosome numbers in the genus. © 2017 Ojanguren-Affilastro et al.

Elevación del piso del seno maxilar con técnica transcrestal.

Introduction: the elevation of the transcrestal floor of the maxillary sinus consists of the vertical reconstruction of the atrophic alveolar ridge in an apical direction, with which it is possible to place the correct number and length of oral implants. Objective: to describe the procedure of a case of transcrestal maxillary sinus floor elevation with the placement of three dental implants. Clinical case: 62 year old female patient with missing teeth 16, 25 and 26. Treatment: three implants were placed to replace the missing teeth. Due to the decrease in height of the remaining alveolar ridge due to pneumatization of the maxillary sinuses, elevation of the sinus floor was planned with the transcrestal Summers¿s technique and placement of graft material. Results: by means of the grafts, sufficient height was achieved for the correct stability of the implants, each área had an average gain of 3 mm in bone height, with which length was obtained to give the implants adequate primary stability. Conclusion: sinus floor elevation with a transcrestal approach is a good alternative for rehabilitation with implants in the posterior edentulous sector, associated with pneumatization of the maxillary sinuses.

SON LAS COSAS DEL QUERER, CLANDESTINIZACIÓN DE LOS AFECTOS, LA SEXUALIDAD Y NUESTRAS IDENTIDADES DESDE LA PERSPECTIVA DE VARONES HOMOSEXUALES DE ORIGEN RURAL DE MICHOACÁN

Jaime Antonio Ferrerira Medina (2023, [Tesis de maestría])

"La homosexualidad en contextos rurales es un tema complejo que ha sido menos estudiado en comparación con las experiencias en entornos urbanos. Sin embargo, existen investigaciones y testimonios que arrojan luz sobre esta cuestión. Los contextos rurales se encuentran impregnados de una serie de discursos que ven la homosexualidad como pecaminosa, criminal y patológica, lo que influye en gran medida en la aceptación y visibilidad de personas homosexuales. Es a partir de esta premisa que el trabajo de investigación analiza ¿cuáles podrían ser las problemáticas a las que se encuentran varones homosexuales en contextos rurales?, tomando como caso las trayectorias afectivas y sexuales de varones originarios de localidades adscritas al Cinturón aguacatero -Berry en Michoacán".

Sexual harassment and stalking in female university students: negative emotions and coping with these forms of gender-based violence

Karla Jazmín Rodríguez Hernández ADRIANA RODRIGUEZ BARRAZA Maria Carolina Agoff (2023, [Artículo, Artículo])

Stalking and sexual harassment, as expressions of gender violence in the field of higher education, are very pressing problems as they have been exhibited by the protest movements that have arisen in Higher Education Institutions. The objective of this work is to analyze the narratives of university women who experienced stalking and/or sexual harassment in Higher Education Institutions in the municipalities of Tampico and Ciudad Madero in the state of Tamaulipas. The purpose was to learn about their experiences and their way of dealing with these forms of gender violence, using qualitative research and a phenomenological design. The technique used for data collection was the semi-structured interview. The selection of the informants was based on intentional sampling and the number of cases examined was guided by the saturation criterion, the total number of participants being thirteen. The analysis of the interviews shows that acts of stalking and sexual harassment provoke various emotions in women that can shed light on the problem of violence from the perspective of the victims, instead of considering only their own explanations, which are often rationalized or consistent with socially legitimized meanings. In sum, the study of emotions allows us to conclude that women within the university context suffer from a psychophysical discomfort that does not allow them to live a full university life.

Los pliegues de la memoria: huellas de la deportación y el exterminio desde los testimonios heredados de las mujeres yaquis.

ALMA YOLANDA GONZALEZ GOMEZ (2023, [Tesis de doctorado])

La presente tesis doctoral es el resultado de una investigación que rescató historias orales de mujeres yaquis sobre la deportación y el exterminio perpetrado contra la tribu durante el porfiriato y los años revolucionarios. El objetivo planteado consistió en identificar las huellas que preservan las mujeres yoeme de ese pasado traumático, con la finalidad de reconstruir una memoria/posmemoria a través de la cual se pueda analizar, comprender y explicar cómo ellas representan y resignifican en sus narrativas esa etapa histórica en el presente.

Se abordó esta temática debido a la invisibilización historiográfica sobre el genocidio yaqui y el silencio histórico de las mujeres yoeme, bajo la hipótesis de que ellas son quienes salvaguardan y repiten transgeneracionalmente las historias escuchadas de los familiares deportados, desaparecidos o reclutados en la leva.

Esta investigación cualitativa requirió dieciocho meses de trabajo de campo en las comunidades yaquis, donde se realizaron entrevistas a mujeres yoeme para integrar un corpus representativo de trece testimonios. La metodología para rescatar las narrativas partió de un enfoque etnográfico e interdisciplinar mediante la historia oral con apoyo en los marcos conceptuales de los estudios de memoria y posmemoria, así como en las nociones de violencia y genocidio, de duelo y giro afectivo/emocional.

Las conclusiones se remiten a los recuerdos individuales de la deportación y el genocidio yaqui como un pasado vivo en el que persiste el duelo inacabado por las muertes y el destierro forzado, el dolor de las ausencias y el odio hacia el yori, las cicatrices de guerra y las violaciones de ancestras, la esclavitud, la persecución, las penalidades de los traslados inhumanos y los regresos a su territorio ancestral, la ruptura social y familiar, entre otros.

Aunque las narrativas recabadas contienen disonancias respecto a los hechos históricos, éstas corresponden a las subjetividades propias de la historia oral recordada.

Aunado a la aportación de las memorias, esta tesis contribuye con un listado nominal inédito de 250 yaquis deportados en 1900 y hallazgos hemerográficos sobre la deportación.

An anion conductance, the essential component of the hydroxyl-radical-induced Ion current in plant roots

IGOR POTTOSIN ALBERTO ISAAC ZEPEDA JAZO JAYACUMAR BOSE (2018, [Artículo])

Oxidative stress signaling is essential for plant adaptation to hostile environments. Previous studies revealed the essentiality of hydroxyl radicals (HO•)-induced activation of massive K+ efflux and a smaller Ca2+ influx as an important component of plant adaptation to a broad range of abiotic stresses. Such activation would modify membrane potential making it more negative. Contrary to these expectations, here, we provide experimental evidence that HO• induces a strong depolarization, from −130 to −70 mV, which could only be explained by a substantial HO•-induced efflux of intracellular anions. Application of Gd3+ and NPPB, non-specific blockers of cation and anion conductance, respectively, reduced HO• induced ion fluxes instantaneously, implying a direct block of the dual conductance. The selectivity of an early instantaneous HO•-induced whole cell current fluctuated from more anionic to more cationic and vice versa, developing a higher cation selectivity at later times. The parallel electroneutral efflux of K+ and anions should underlie a substantial leak of the cellular electrolyte, which may affect the cell’s turgor and metabolic status. The physiological implications of these findings are discussed in the context of cell fate determination, and ROS and cytosolic K+ signaling
