La esencia de la comunicación consiste en algo tan mágico como trasladar una idea que existe en nuestra mente a la de otra persona. Y si lo que queremos es persuadir a alguien, tenemos que hacer un esfuerzo para lograr algo aún más parecido a la magia, que es conseguir que ese pensamiento surja en la cabeza de nuestro interlocutor como algo natural, sin que sea percibida cualquier intervención externa.De esto trata este libro sorprendente en el que, aprovechando el legado de algunos de los ilusionistas más prestigiosos se propone una serie de prácticas que harán más efectiva la forma de comun

The present article aims to initiate a conversation with Alena Rettová on her article "Post-Genocide, Post-Apartheid: The Shifting Landscapes of African Philosophy, 1994-2019" that was published in Modern Africa in the Summer of 2021. We identify several issues in her historical account of African philosophical thoughts that need polyphonic engagement in order to ensure that Africa's pluralistic intellectual heritage is not reduced to a monophonic one. We are intentional at being Rettová's intellectual dialogical partner on the reading of African philosophy, while bearing in mind that the ideologies of apartheid and genocide are still active. While we explore some key aspects of her work, we also acknowledge that African philosophy is constantly in the making and it would be problematic to use the yardstick of one context, in this case, the Western context, as a benchmark in order to account for the progression of philosophical thoughts in other philosophical contexts (Africa) without taking into account the historical peculiarities of each context.

"This edited collection focuses on the uncelebrated insights and perspectives of women of color in a world where systemic discrimination persists. It articulates new strategies and paradigms for recognizing their contributions to the broader struggles for freedom and equity of women in our world"--

While artificial insemination (AI) with frozen-thawed sperm results in low fertility rates in donkeys, the addition of seminal plasma, removed during cryopreservation, partially counteracts that reduction. Related to this, an apparent inflammatory reaction in jennies is induced following AI with frozen-thawed sperm, as a high amount of polymorphonuclear neutrophils (PMN) are observed within the donkey uterus six hours after AI. While PMN appear to select the sperm that ultimately reach the oviduct, two mechanisms, phagocytosis and NETosis, have been purported to be involved in that clearance. Remarkably, sperm interacts with PMN, but the presence of seminal plasma reduces that binding. As seminal plasma is a complex fluid made up of different molecules, including proteins, this study aimed to evaluate how different seminal plasma fractions, separated by molecular weight (100 kDa), affect sperm-PMN binding. Sperm motility, viability, and sperm-PMN binding were evaluated after 0 h, 1 h, 2 h, 3 h, and 4 h of co-incubation at 38 °C. Two seminal plasma fractions, including 30-50 kDa or 50-100 kDa proteins, showed the highest sperm motility and viability. As viability of sperm not bound to PMN after 3 h of incubation was the highest in the presence of 30-50 and 50-100 kDa proteins, we suggest that both fractions are involved in the control of the jenny's post-breeding inflammatory response. In conclusion, this study has shown for the first time that specific fractions rather than the entire seminal plasma modulate sperm-PMN binding within the donkey uterus. As several proteins suggested to be involved in the control of post-AI endometritis have a molecular weight between 30 and 100 kDa, further studies aimed at determining the identity of these molecules and evaluating their potential effect in vivo are much warranted ; This research was supported by the Ministry of Science and Innovation, Spain (Grants: RYC2014–15581 and AGL2017-88329-R), and the Regional Government of ...

This study sought to determine whether single layer centrifugation (SLC) of fresh donkey semen with Equicoll has any impact on sperm quality parameters and on the modulation of endometrial reaction following semen deposition using an in vitro model. Seventeen ejaculates from five jackasses were obtained using an artificial vagina and diluted in a skim-milk extender. Samples were either selected through SLC (Equicoll) or non-treated (control). Two experiments were performed. The first one consisted of incubating selected or non-selected spermatozoa at 38 °C for 180 min. Integrity and lipid disorder of sperm plasma membrane, mitochondrial membrane potential, and intracellular levels of calcium and reactive oxygen species were evaluated at 0, 60, 120, and 180 min. In the second experiment, polymorphonuclear neutrophils (PMN) isolated from jennies blood were mixed with selected and unselected spermatozoa. Interaction between spermatozoa and PMN was evaluated after 0, 60, 120, and 180 min of co-incubation at 38 °C. SLC-selection increased the proportions of spermatozoa with an intact plasma membrane and low lipid disorder, of spermatozoa with high mitochondrial membrane potential and with high calcium levels, and of progressively motile spermatozoa. In addition, selection through SLC augmented the proportion of phagocytosed spermatozoa, which supported the modulating role of seminal plasma proteins on sperm-PMN interaction. In conclusion, SLC of fresh donkey semen increases the proportions of functionally intact and motile spermatozoa, and appears to remove the seminal plasma proteins that inhibit sperm-PMN binding ; This research was supported by the Ministry of Science, Innovation and Universities, Spain (Grants: RYC-2014-15581 and AGL2017-88329-R), and the Regional Government of Catalonia (2017-SGR-1229).

Jenny shows a large endometrial reaction after semen influx to the uterus with a large amount of polymorphonuclear neutrophils (PMN) migrating into the uterine lumen. PMN act as a sperm selection mechanism through phagocytosis and NETosis (DNA extrudes and, together with proteins, trap spermatozoa). While a reduced percentage of spermatozoa are phagocytosed by PMN, most are found to be attached to neutrophil extracellular traps (NETs). This selection process together with sperm metabolism produces a large amount of reactive oxygen species (ROS) that influence the reproductive success. The present study aimed to determine the extracellular ROS production in both sperm and PMN. With this purpose, (1) donkey sperm were exposed to reductive and oxidative stresses, through adding different concentrations of reduced glutathione (GSH) and hydrogen peroxide (H2O2), respectively; and (2) PMN were subjected to NETosis in the presence of the whole semen, sperm, seminal plasma (SP) or other activators such as formyl-methionyl-leucyl-phenylalanine (FMLP). Extracellular ROS production (measured as H2O2 levels) was determined with the Amplex® Red Hydrogen Peroxide/Peroxidase Assay Kit. Donkey sperm showed more resilience to oxidative stress than to the reductive one, and GSH treatments led to greater H2O2 extracellular production. Moreover, not only did SP appear to be the main inducer of NETosis in PMN, but it was also able to maintain the extracellular H2O2 levels produced by sperm and NETosis ; I.Y.-O. was funded by the Secretary of Higher Education, Science, Technology and Innovation (SENESCYT), Ecuador (Scheme: Programa de Becas Internacionales de Posgrado 2019; Grant: CZ02-000507-2019).
