First record of nucleus migration in premeiotic antherial cells of Saccharum spontaneum L. (Poaceae)
Authors: Singh Chandra Bhanu , Singhal Vijay Kumar , Kapoor Manish 
Published: May 2023

The occurrence of nucleus migration is reported for the first time in a clone (2n = 64) of ‘Thatch’ grass (Saccharum spontaneum L.) of the family Poaceae. Usually, its premeiotic antherial cells are thin walled, uninucleate and without any trace of chromosome individuality. However, the cells of those anthers that had been affected from flood water stress conditions were anucleated to hexanucleated in varying frequencies. Out of 2567 cells analyzed, two and three cells were noticed to be connected to each other through a well-defined cytoplasmic channel. The nuclei were observed at various stages of their migration in interconnected cells. The remaining cells exhibited a mosaic of anucleate to hexanucleate cells in varying frequencies with a dominance of binucleated condition (43.75%). The anucleate ‘ghost’ cells were much smaller in size than the uninucleate, binucleate and multinucleate cells showing insignificant variation among themselves. The anucleate, binucleate and multinucleate cells appeared to be resulted due to nucleus migration through cytoplasmic channels between two cells. The presence of a nucleus in donor cell united with recipient cell having four nuclei of different sizes, diminutive anucleate cell in the neighbourhood of uninucleate/trinucleate cell or connected with cytoplasmic channel/pentanucleate cell, and disorganizing cytoplasmic channel attached with binucleate/ tetranucleate cell witnessed the accomplishment of nucleus migration. This rare phenomenon of nucleus migration seemed to be triggered by flood water induced stress and facilitated by feeble cell wall. The variation in sizes of nuclei in multinucleate cells might be due to the transfer of nucleus/nuclei of different size(s). The prominent features of nucleus migration distinguishing it from the cytomixis have been discussed in detail. The syncytes resulted due to nucleus migration might have generated the pollen grains with different genetic constitution resulting into the origin of new intraspecific aneuploids/ polyploids for better adaptability.
El poder masculino en el marco de la feminización de enfermería en la academia

Published: May 2023

En la actualidad, se ha incentivado de sobre manera -en el discurso de las políticas públicas y gubernamentales-, la importancia de igualdad y equidad entre hombres y mujeres. Esto ha traído aparejado la propuesta de reconfiguraciones profundas respecto a los roles que tradicionalmente se asumían derivados de la condición de género; el cuidado no ha quedado fuera del radar de estas transformaciones, pues se trata de una actividad generizada; históricamente el cuidado se ha visto como un asunto “de las mujeres”, incluso cuando se ejerce de forma profesional.
Si bien la Enfermería ha sido una profesión feminizada, en los últimos veinte años las Universidades de México que ofertan estos programas de Licenciatura han visto incrementar la presencia masculina dentro de sus matrículas y plantas docentes, y aunque si bien la inclusión de los hombres en el cuidado puede representar una oportunidad, es necesario analizar como esta condición modifica el escenario del cuidado y de forma más específica los contextos en los que se ejerce y educa para el cuidado profesional, en virtud de las conductas observadas de las propias mujeres en torno al empoderamiento que otorgan a los varones en espacios de toma de decisiones por esta característica de género e invisibilizando la preparación académica y otros componentes importantes para el desarrollo de liderazgo para la potencialización de las funciones sustantivas de la Universidad.
Cabe hacer mención que esta revisión y reflexión se deriva de un contexto particular en donde se devela la existencia de un retroceso ideológico gremial que resta al protagonismo de las mujeres en la toma de decisiones institucionales, así como en el desarrollo académico y de investigación, situaciones que urgen a la formulación de propuestas que permitan erradicar las desigualdades e inequidades y democratizar el poder de las instituciones reconociendo la capacidad, desarrollo profesional y de investigacion de hombres y mujeres en el ámbito educativo de enfermería.

To be or not to be relevant: Comparing short- and long-term consequences across working memory prioritization procedures

Published: May 2023

AbstractPriority-based allocation of attentional resources has shown robust effects in working memory (WM) with both cue-based and reward-based prioritization. However, direct comparisons between these effects in WM are needed. Additionally, the consequences of WM prioritization for remembering in the long term remain unclear for both prioritization procedures. Here, we tested and compared the immediate and long-term memory (LTM) effects of cue-based versus reward-based retrospective prioritization of WM content. Participants encoded four memory items and were then indicated to prioritize one of the items through the presentation of either a retro-cue or a reward pattern. We then tested their immediate and delayed memory. The results of the first experiment showed better memory for prioritized than for unprioritized information in WM and LTM, but the WM effect was driven solely by the retro-cue, making it difficult to interpret any reward-based effects in LTM. In the second experiment, using a more explicit and meaningful reward-based manipulation, the results showed a prioritization benefit in WM for both prioritization procedures. In LTM, however, the prioritization effect was predominantly driven by the retro-cue manipulation. Taken together, we found that (1) the way in which attention is directed in WM impacts the size of the prioritization benefit in WM, (2) WM prioritization generally results in a prioritization effect in LTM, and (3) that the effect in LTM is more robust for cue-based prioritization. Exploratory analyses indicated that the LTM effect of cue-based prioritization reflected a cost in performance for noncued items rather than a benefit for cued items.

Abstract
Optical and near-IR photometry suggests that the carbon star DY Persei exhibits fadings similar to those of R Coronae Borealis (RCB) variables. Photometric surveys of the Galaxy and Magellanic Clouds uncovered new DY Per variables with infrared photometry identifying them with cool carbon stars, perhaps, with an unusual tendency to shed mass. In an attempt to resolve DY Per’s identity crisis—a cool carbon giant or a cool RCB variable?—we analyze a high-resolution IGRINS H&K-band spectrum of DY Per. The CO first-overtone bands in the K band of DY Per show a high abundance of 18O such that 16O/18O = 4 ± 1, a ratio sharply at odds with published results for regular cool carbon giants with 16O/18O ∼ 1000 but this exceptionally low ratio is characteristic of RCB variables and HdC stars. This similarity suggests that DY Per indeed may be a cool RCB variable. Current opinion considers RCB variables to result from the merger of a He onto a CO white dwarf; observed abundances of these H-deficient stars including the exceptionally low 16O/18O ratios are in fair accord with predicted compositions for white dwarf merger products. An H-deficiency for DY Per is not directly observable but is suggested from the strength of an HF line and an assumption that F may be overabundant, as observed and predicted for RCB stars.

Published: May 2023

ObjectiveAbnormal functional connectivity (FC) and structure in the brain are found in patients with fibromyalgia (FM). This study investigated FC and structural alterations of the visual cortical system, the emerging contributor to pain processing, in patients with FM.MethodsThirty pain-free participants and 26 patients with FM were enrolled. Clinical characteristics were evaluated using standardized scales. Structural and resting-state functional magnetic resonance imaging were conducted. Seed-based FC analyses, voxel-based morphometry, and surface-based morphometry were performed. The FC and cortical structure of the visual system were compared between the 2 groups. The correlation between functional and structural changes in the visual cortical system with clinical presentation in the FM group was analyzed.ResultsThe patients with FM showed increased FCs within visual networks, of which the FC between the visual medial network and the right lingual gyrus (LG) was positively correlated with the Fibromyalgia Impact Questionnaire (FIQ) score. However, the FM group showed decreased FCs from the visual occipital network (VON) to several regions, of which the FCs from the VON to the bilateral frontal orbital cortices were negatively correlated with the FIQ and Pittsburgh Sleep Quality Index scores. Cortical thickness of the lateral occipital cortex, LG, and pericalcarine in FM tended to increase.ConclusionAltered FCs and structure in the visual cortical system might be involved in the pathomechanisms and clinical presentation in FM. These findings could potentially support further studies that seek to find diagnostic methods and mechanism-based therapies in patients with FM.
À leur façon de s’habiller ce sont des barbares. Les Carthaginois stigmatisés par leurs ennemis dans la tradition classique
Authors: Ben Mansour Manel 
Published: May 2023

Le monde savant moderne n’a pas manqué de noter que l’habit sert à construire l’identité. Conscients à leur tour que les identités s’expriment, entre autres, à travers les apparences, Plaute et Timée focalisent alors sur le goût vestimentaire punique afin de stigmatiser les Carthaginois et les dépeindre comme un peuple barbare et indolent. Il s’avère que le souci de barbariser les Carthaginois à travers l’accoutrement était un souci partagé. Ainsi, rien de surprenant si Diodore de Sicile insiste sur l’habillement en lambeaux porté par Himilcon après sa défaite devant les murailles de Syracuse ; détail qui n’est pas sans rappeler l’image de Xerxès I de retour à Suse dans les Perses d’Eschyle. Quant à Polybe, et sur un ton inhabituel chez lui, il préfère plutôt décrire la chlamyde de pourpre bariolée portée par le dernier dirigeant carthaginois Hasdrubal. Ainsi, et par de petites touches, il dépeint un général carthaginois efféminé exerçant un pouvoir absolu sur une cité endeuillée.
« Uberrima, fateor, mundi pars est Africa » : la saveur des Carthaginois dans l’Africa de Pétrarque
Authors: Cazeaux Mathilde 
Published: May 2023

Par le titre même d’Africa qu’il choisit pour son épopée à la gloire de Scipion, Pétrarque attire l’attention de son lectorat sur ses représentations de la terre d’Afrique, qui s’y manifeste surtout par ses habitants. À côté d’une représentation collective négative des Carthaginois, héritée des auteurs anciens, il façonne des personnages complexes, Hannibal, Sophonisbe, Magon et Hasdrubal le Chevreau. Ceux-ci sont plus que de simples faire-valoir de Scipion : ils donnent leur saveur au texte en incarnant l’humanité dans ses passions.
Les Ibères à l’école de l’Orient… mais quel Orient ? Quelques notes autour de la question phénicienne
Authors: Reimond Grégory 
Published: May 2023

Entre la fin du xixe et le début du xxe siècle, la découverte d’une nouvelle culture méditerranéenne, celle des Ibères, est avant tout le fait d’hommes de science pétris de culture classique. Qu’il s’agisse d’étudier leur grande sculpture en pierre ou leurs productions céramiques, les débats s’attachent d’abord à en démêler l’origine en partant du principe qu’un peuple « barbare » ne peut avoir donné naissance à lui seul à une culture matérielle originale. Il a nécessairement été éduqué par des voisins plus « civilisés ». Les discussions tournent en partie autour de la part qu’il convient de réserver aux influences grecques et phénico-puniques. Un tel dossier permet donc de saisir le regard que portent les érudits d’alors sur les mondes phéniciens et carthaginois, sur leur art et, partant, sur leur goût. Leurs discours s’élaborent dans un contexte bien particulier qui se reflète avec force dans la production historiographique d’alors : celui de La France juive d’Édouard Drumont et de l’affaire Dreyfus.
Age-Dependent Normalization Functions for T Lymphocytes in Healthy Individuals

Published: May 2023

Abstract
Lymphocyte numbers naturally change through age. Normalization functions to account for this are sparse and mostly disregard measurements from children in which these changes are most prominent. In this study, we analyze cross-sectional numbers of mainly T lymphocytes (CD3+, CD3+CD4+, and CD3+CD8+) and their subpopulations (naive and memory) from 673 healthy Dutch individuals ranging from infancy to adulthood (0–62 y). We fitted the data by a delayed exponential function and estimated parameters for each lymphocyte subset. Our modeling approach follows general laboratory measurement procedures in which absolute cell counts of T lymphocyte subsets are calculated from observed percentages within a reference population that is truly counted (typically the total lymphocyte count). Consequently, we obtain one set of parameter estimates per T cell subset representing both the trajectories of their counts and percentages. We allow for an initial time delay of half a year before the total lymphocyte counts per microliter of blood start to change exponentially, and we find that T lymphocyte trajectories tend to increase during the first half a year of life. Thus, our study provides functions describing the general trajectories of T lymphocyte counts and percentages of the Dutch population. These functions provide important references to study T lymphocyte dynamics in disease, and they allow one to quantify losses and gains in longitudinal data, such as the CD4+ T cell decline in HIV-infected children and/or the rate of T cell recovery after the onset of treatment.
Deficiencies and Dysregulation of STAT Pathways That Drive Inborn Errors of Immunity: Lessons from Patients and Mouse Models of Disease
Authors: Toth Kelsey A , Schmitt Erica G , Cooper Megan A 
Published: May 2023

Abstract
The STAT family proteins provide critical signals for immune cell development, differentiation, and proinflammatory and anti-inflammatory responses. Inborn errors of immunity (IEIs) are caused by single gene defects leading to immune deficiency and/or dysregulation, and they have provided opportunities to identify genes important for regulating the human immune response. Studies of patients with IEIs due to altered STAT signaling, and mouse models of these diseases, have helped to shape current understanding of the mechanisms whereby STAT signaling and protein interactions regulate immunity. Although many STAT signaling pathways are shared, clinical and immune phenotypes in patients with monogenic defects of STAT signaling highlight both redundant and nonredundant pathways. In this review, we provide an overview of the shared and unique signaling pathways used by STATs, phenotypes of IEIs with altered STAT signaling, and recent discoveries that have provided insight into the human immune response and treatment of disease.

ABSTRACT

Background and Objectives:
EUS-guided tissue acquisition is routinely performed for the diagnosis of gastrointestinal tract and adjacent organ lesions. Recently, various types of needles have been developed. However, how the shape of the needle tip and echoendoscope tip angle affect puncturability, has not been clarified. The aim of this experimental study was to compare the puncturability of several 22-gauge EUS-FNA and EUS-guided fine-needle biopsy (EUS-FNB) needles, and to evaluate the effects of the needle tip shape and echoendoscope tip angle on tissue puncturability.

Materials and Methods:
The following six major FNA and FNB needles were evaluated: SonoTip® ProControl, EZ Shot 3 Plus, Expect™ Standard Handle, SonoTip® TopGain, Acquire™, and SharkCore™. The mean maximum resistance force against needle advancement was evaluated and compared under several conditions using an echoendoscope.

Results:
The mean maximum resistance force of the needle alone was higher for the FNB needles than for the FNA needles. The mean maximum resistance force of the needle in the echoendoscope with free angle demonstrated that the resistance forces were between 2.10 and 2.34 Newton (N). The mean maximum resistance force increased upon increases in angle of the tip of echoendoscope, particularly in the FNA needles. Among the FNB needles, SharkCore™ had the lowest resistance force (2.23 N). The mean maximum resistance force of the needle alone, the needle in the echoendoscope with free angle, and the needle in the echoendoscope with full-up angle for SonoTip® TopGain were all similar to that of Acquire™.

Conclusion:
SonoTip® TopGain had similar puncturability to Acquire™ in all tested situations. Regarding the puncturability, SharkCore™ is most suitable for insertion into target lesions, when tight echoendoscope tip angle is necessary.

ABSTRACT
As part of the aging process, fibrotic changes, fatty infiltration, and parenchymal atrophy develop in the pancreas. The pancreatic duct also becomes wider with age. This article provides an overview of the diameter of the pancreatic duct in different age groups and different examination methods. Knowledge of these data is useful to avoid misinterpretations regarding the differential diagnosis of chronic pancreatitis, obstructive tumors, and intraductal papillary mucinous neoplasia (IPMN).
