The female of A. rebecae sp. nov. also has a similar trapezoidal atrium, and copulatory duct paths (Fig. 28E–F), but it differs from that of A. franciscoi sp. nov. by the notched hood and smaller size (7.23 ±1.1). Anyphaena sofiae sp. nov. shares similar copulatory duct paths and spermathecal proportions with both species, but differs by the oval atrium and copulatory ducts extending beyond the hood (Fig. 36E–F). Etymology The species epithet is dedicated to Francisco Rivera, father of the first author.

Cardiovascular implantable electronic devices in hemodialysis patients: an updated review
No full textCardiovascular diseases are the leading life-threatening complications in hemodialysis patients. In this scenario, both tachy-arrhythmias and brady-arrhythmias are involved with related hemodialysis and nonhemodialysis-dependent mechanisms; moreover, those arrhythmias usually occur in different time intervals before sudden cardiac death (SCD). Furthermore, current evidence shows that the presence of advanced chronic kidney disease (CKD) reduces the benefits of implantable cardioverter--defibrillators (ICDs), which increases the risk of both arrhythmic and nonarrhythmic death, especially in patients with advanced stages of heart failure. Notably, patients with advanced CKD show a more severe degree of heart failure compared with mild CKD patients. However, the benefits of the ICD implantation in the primary prevention of hemodialysis patients is still controversial, and by now, no significant benefits have emerged compared with nonhemodialysis-dependent CKD patients. In secondary prevention, hemodialysis patients with ICD implantation have higher mortality rates compared with nonhemodialysis-dependent CKD patients with ICD. On the other hand, most articles include hemodialysis patients with reduced left ventricular ejection fraction, neglecting those with preserved systolic function. This review focuses on the epidemiology of SCD in the setting of hemodialysis and the current evidence on ICD implantation in patients on hemodialysis therapy analyzing novel strategies, which might reduce the risk of ICD placing

The female of A. franciscoi sp. nov. also has a similar trapezoidal atrium and copulatory duct paths (Fig. 17E–F), but differs from that of A. rebecae sp. nov. by the central part of the atrium being convex and its larger size (9.6 ± 1.1). The females of A. sofiae sp. nov. share with both species similar copulatory duct paths and spermathecae proportions, but differ by the oval atrium and copulatory ducts extending beyond the hood (Fig. 36E–F). Males can be differentiated by the presence of the following features: median apophysis hook-shaped and with a ventral transparent lamella, ventral tegular projection distal section widest, middle section constricted, retrolateral border with a transparent cuticular edge,prolateral border with a basal protuberance (Figs 29A–B, D, 30 A–B, D), RTA posterior branch roughly squared with a spine-shaped process on its anterior border (Figs 29D, F, 30D). Ventral tegular projections with broad middle sections and translucent retrolateral edges are also present in A. zorynae and A. zuyelenae Durán-Barrón, Pérez & Brescovit, 2016 (Durán-Barrón et al. 2016: figs 5, 9, 12, 16), A. pectorosa and A. pacifica (Platnick 1974: figs 51, 55, 59, 63), A. porta sp. nov.

Figuraciones sesgadas: teatralidad, intermedialidad y yo autoral en Cristina Rivera Garza
No full textIn the work of Mexican writer Cristina Rivera Garza (Matamoros, 1964), strategies of autofiction in lyric and narrative are frequently used. Although author itself has scrutinized on the affordances and contradictions of writings of the self, especially in her essay The Restless Dead (2020), scholarship hasn’t work on it enough. In this article I study how self-representation are mediated through intermedial references in Rivera Garza’s books. In the first section, after discussing the relevance of self-representation as a problem in the lyric, I analyze its forms in both La más mía (1998) and La imaginación pública (2015) to locate a critical reflection on the self. In the second section, I consider the reference to author’s grandmother in Autobiografía del algodón (2020) as an oblique thinking on writing and its material conditions.A lo largo de la obra de la escritora mexicana Cristina Rivera Garza (Matamoros, 1964) con frecuencia aparecen estrategias de la autoficción narrativa y lírica. Aunque la propia autora ha reflexionado sobre las posibilidades y contradicciones de las escrituras del yo, especialmente en Los muertos indóciles (2013), la crítica se ha ocupado poco de este problema. En este artículo propongo mostrar que en la obra de Rivera Garza las figuraciones del yo aparecen mediadas por referencias intermediales. En el primer apartado, tras discutir la pertinencia de pensar la autoficción en la lírica, analizo su presencia en el libro La más mía (1998) y en La imaginación pública (2015) para identificar los reflejos críticos del yo. En el segundo, analizo la referencia a la fotografía de la abuela de la autora en Autobiografía del algodón (2020) como una reflexión oblicua sobre la escritura y sus condiciones materiales

Fibroblast growth factor 23 and parathyroid hormone predict extent of aortic valve calcifications in patients with mild to moderate chronic kidney disease
No full textCardiac valve calcifications are present in dialysis patients and regarded as dependent on a deranged mineral metabolism. Few data are available for patients with chronic kidney disease (CKD) not on dialysis. This study evaluates the potential association between the extent of cardiac valve calcification and levels of intact parathyroid hormone (i-PTH), phosphorus, calcium, 25-OH vitamin D, fibroblast growth factor 23 (FGF-23), Klotho and C-reactive protein (CRP) simultaneously measured in patients with mild to moderate CKD
