Viruela del mono: nuevo reto de salud mundial

Fernando Roger Esquivel Guadarrama (2024, [Artículo])

El virus de la viruela del mono ha tomado un papel protagónico en el universo de las enfermedades infecciosas en los últimos dos años. La preocupación por los brotes de este virus que surgieron en distintas partes del mundo colocaron esta enfermedad en el centro de la atención pública, porque se creía que no existía tratamiento o vacuna específica para ella. La buena noticia es que su letalidad no es muy alta y existen tratamientos y medidas de prevención alternativas, creadas originalmente para el virus de la viruela humana. En este artículo se exponen los aspectos más relevantes de este virus y el curso de la enfermedad que genera, así como las medidas de tratamiento y prevención más usadas en la actualidad.

The monkeypox virus has taken a leading role in the universe of infectious diseases in the last two years. Concern about out-breaks of this virus that emerged in different parts of the world placed this disease in the public spotlight, because it was believed that there was no specific treatment or vaccine for it. The good news is that its lethality is not very high and that there are alternative treatments and prevention measures, originally created for the human smallpox virus. This article presents the most relevant aspects of the virus and the course of the disease it generates, as well as the most commonly used treatment and prevention measures.

Re-establishment of the genus Pseudalbizzia (Leguminosae, Caesalpinioideae, mimosoid clade): the New World species formerly placed in Albizia

Following recent mimosoid phylogenetic and phylogenomic studies demonstrating the non-monophyly of the genus Albizia, we present a new molecular phylogeny focused on the neotropical species in the genus, with much denser taxon sampling than previous studies. Our aims were to test the monophyly of the neotropical section Arthrosamanea, resolve species relationships, and gain insights into the evolution of fruit morphology. We perform a Bayesian phylogenetic analysis of sequences of nuclear internal and external transcribed spacer regions and trace the evolution of fruit dehiscence and lomentiform pods. Our results find further support for the non-monophyly of the genus Albizia, and confirm the previously proposed segregation of

Hesperalbizia, Hydrochorea, Balizia and Pseudosamanea. All species that were sampled from section Arthrosamanea form a clade that is sister to a clade composed of Jupunba, Punjuba, Balizia and Hydrochorea. We find that lomentiform fruits are independently derived from indehiscent septate fruits in both Hydrochorea and section Arthrosamanea. Our results show that morphological adaptations to hydrochory, associated with shifts into seasonally flooded habitats, have occurred several times independently in different geographic areas and different lineages within the ingoid clade. This suggests that environmental conditions have likely played a key role in the evolution of fruit types in Albizia and related genera. We resurrect the name Pseudalbizzia to accommodate the species of section Arthrosamanea, except for two species that were not sampled here but have been shown in other studies to be more closely related to other ingoid genera and we restrict the name Albizia s.s. to the species from Africa, Madagascar, Asia, Australia, and the Pacific. Twenty-one new nomenclatural combinations in Pseudalbizzia are proposed, including 16 species and 5 infraspecific varietal names. In addition to the type species Pseudalbizzia berteroana, the genus has 17 species distributed across tropical regions of the Americas, including the Caribbean. Finally, a new infrageneric classification into five sections is proposed and a distribution map of the species of Pseudalbizzia is presented.

REAL TIME EMBBEDED RGB-D SLAM USING CNNS FOR DEPTH ESTIMATION AND FEATURE EXTRACTION

Marcos Renato Rocha Hernández (2023, [Tesis de maestría])

"A robust and efficient Simultaneous Localization and Mapping (SLAM) system is essential for intelligent mobile robots to work in unknown environments. For visual SLAM algorithms, though the theoretical framework has been well established for most aspects, feature extraction and association is still empirically de signed in most cases, and can be vulnerable in complex environments. Also, most of the most robust SLAM algorithms rely on special devices like a stereo camera or depth sensors, which can be expensive and give more complexity to the system, that is why monocular depth estimation is an essential task in the computer vision community. This work shows that feature extraction and depth estimation using a monocular camera with deep convolutional neural networks (CNNs) can be incorporated into a modern SLAM framework. The proposed SLAM system utilizes two CNNs, one to detect keypoints in each im age frame, and to give not only keypoint descriptors, but also a global descriptor of the whole image and the second one to make depth estimations from a single image frame, all using only a monocular camera."

Litsea glaucescens Kuth possesses bactericidal activity against Listeria monocytogenes

LAURA PATRICIA ALVAREZ BERBER SILVIA MARQUINA BAHENA (2023, [Artículo])

Litsea glaucencens Kuth is an aromatic plant used for food seasoning food and in Mexican traditional medicine. Among, L. glaucencens leaves properties, it has proven antibacterial activity which can be used against opportunistic pathogens like Listeria monocytogenes, a foodborne bacteria that is the causal agent of listeriosis, a disease that can be fatal in susceptible individuals. The aim of this work was to investigate the antibacterial activity of L. glaucescens Kuth leaf extracts against L. monocytogenes and to identify its bioactive components.

Pablo Palacio en la vanguardia

ANTONIO VLADIMIRO RIVAS ITURRALDE (2019, [Artículo])

Artículo número 9 de la Sección Tema. 14 páginas. tyvllii

Pablo Palacio (Loja, Ecuador, 1906-1947) es uno de los grandes escritores de la vanguardia en Hispanoamérica. Poco conocido hace años, las ediciones de su obra y los estudios sobre ella han ido creciendo en forma exponencial desde la década del 70. En medio del realismo social de la narrativa ecuatoriana y latinoamericana de los años veinte y treinta, Palacio se atrevió a crear una narrativa ambigua, diferente, de gran audacia formal, vanguardista. Descubrió por su propia cuenta el monólogo interior y escribió quizás la primera novela collage de la literatura hispanoamericana. Reivindicado, entre otros, por críticos como Jorge Ruffinelli, Antonio Cornejo Polar, José Miguel Oviedo y Julio Ortega, ha merecido ya la edición crítica de Archivos del Fondo en colaboración con la unesco.

Pablo Palacio (Loja, Ecuador, 1906-1947) is one of the great vanguardist writers of Latin America. Although little known a few years ago, his popularity has increased because of the growing editions of his works and the numerous studies dedicated to him. During the period of the social realism, Palacio dared a different, ambiguous, formally audacious, and vanguardist narrative. He discovered by his own the inner monologue and wrote the first collage novel in Latin American literature. Many foremost critics have vindicated his work, such as Jorge Ruffinelli, Antonio Cornejo Polar, José Miguel Oviedo and Julio Ortega, among others, and has been edited critically by Archivos del Fondo in collaboration with the UNESCO.

Efficiency of combating property violence in the Northwest region of Mexico

Martin Flegl Eva Selene Hernández Gress (2023, [Artículo, Artículo])

The situation of violence in Mexico shows an alarming trend as the number of committed crimes increased by 10.9% in 2021 compared to 2020. In fact, 75.6% of the Mexican population perceives the insecurity. Due to the above, it is necessary to strengthen public security to combat this trend. However, the resources allocated to the public security in Mexico are limited. Although there are studies that investigate what causes the violence in Mexico, so far there is no study that measures the efficiency of combating the violence related to budgetary, human, and material resources of the public security. This article investigates the efficiency of combating the property violence in 206 municipalities in the Northwest region of Mexico through the Data Envelopment Analysis. The results show a low efficiency (56.67%) with significant differences between the states in the region. Baja California is the state with the lowest efficiency (17.61%), whereas the highest efficiency is found in Durango (67.25%). For the last, the need to carefully plan changes in the police force and the public security infrastructure was noted to improve the efficiency and the level of security.
