Multisession Anodal Transcranial Direct Current Stimulation Enhances Adult Hippocampal Neurogenesis and Context Discrimination in Mice
Authors: Yu Ting-Hsuan , Wu Yi-Jen , Chien Miao-Er , Hsu Kuei-Sen
Published: December 2022

Transcranial direct current stimulation (tDCS) is a promising noninvasive neuromodulatory treatment option for multiple neurologic and psychiatric disorders, but its mechanism of action is still poorly understood. Adult hippocampal neurogenesis (AHN) continues throughout life and is crucial for preserving several aspects of hippocampal-dependent cognitive functions. Nevertheless, the contribution of AHN in the neuromodulatory effects of tDCS remains unexplored. Here, we sought to investigate whether multisession anodal tDCS may modulate AHN and its associated cognitive functions. Multisession anodal tDCS were applied on the skull over the hippocampus of adult male mice for 20 min at 0.25 mA once daily for 10 d totally. We found that multisession anodal tDCS enhances AHN by increasing the proliferation, differentiation and survival of neural stem/progenitor cells (NSPCs). In addition, tDCS treatment increased cell cycle reentry and reduced cell cycle exit of NSPCs. The tDCS-treated mice exhibited a reduced GABAergic inhibitory tone in the dentate gyrus compared with sham-treated mice. The effect of tDCS on the proliferation of NSPCs was blocked by pharmacological restoration of GABABreceptor-mediated inhibition. Functionally, multisession anodal tDCS enhances performance on a contextual fear discrimination task, and this enhancement was prevented by blocking AHN using the DNA alkylating agent temozolomide (TMZ). Our results emphasize an important role for AHN in mediating the beneficial effects of tDCS on cognitive functions that substantially broadens the mechanistic understanding of tDCS beyond its well-described in hippocampal synaptic plasticity.

SIGNIFICANCE STATEMENTTranscranial direct current stimulation (tDCS) has been shown to effectively enhance cognitive functions in healthy and pathologic conditions. However, the mechanisms underlying its effects are largely unknown and need to be better understood to enable its optimal clinical use. This study shows that multisession anodal tDCS enhances adult hippocampal neurogenesis (AHN) and therefore contributes to enhance context discrimination in mice. Our results also show that the effect of tDCS on AHN is associated with reduced GABAergic inhibition in the dentate gyrus. Our study uncovers a novel mechanism of anodal tDCS to elicit cognitive-enhancing effects and may have the potential to improve cognitive decline associated with normal aging and neurodegenerative disorders.

In brief

The endocrine and immunological disruption induced by hyperthyroidism could alter gestation, placenta, and fetal development. This study suggests an immunological role of thyroid hormones in gestation.

Thyroid dysfunctions lead to metabolic, angiogenic, and developmental alterations at the maternal–fetal interface that cause reproductive complications. Thyroid hormones (THs) act through their nuclear receptors that interact with other steroid hormone receptors. Currently, immunological regulation by thyroid status has been characterized to a far less extent. It is well known that THs exert regulatory function on immune cells and modulate cytokine expression, but how hyperthyroidism (hyper) modulates placental immunological aspects leading to placental alterations is unknown. This work aims to throw light on how hyper modulates immunological and morphological placental aspects. Control and hyper (induced by a daily s.c. injection of T4 0.25 mg/kg) Wistar rats were mated 8 days after starting T4 treatment and euthanized on days 19 (G19) and 20 (G20) of pregnancy. We removed the placenta to perform qPCR, flow cytometry, immunohistochemistry, Western blot and histological analysis, and amniotic fluid and serum to evaluate hormone levels. We observed that hyper increases the fetal number, fetal weight, and placental weight on G19. Moreover, hyper induced an endocrine imbalance with higher serum corticosterone and changed placental morphology, specifically the basal zone and decidua. These changes were accompanied by an increased mRNA expression of glucocorticoid receptor and monocyte chemoattractant protein-1, an increased mRNA and protein expression of prolactin receptor, and an increase in CD45+ infiltration. Finally, by in vitro assays, we evidenced that TH induced immune cell activation. In summary, we demonstrated that hyper modulates immunological and morphological placental aspects and induces fetal phenotypic changes, which could be related to preterm labor observed in hyper.

Published: December 2022

This paper presents and reflects on a teaching proposal for the initial training of History teachers designed in a public university in Argentina, which has historical time as its axis and which is part of a final postgraduate project, of the University of Córdoba, Faculty of Philosophy and Humanities, defended this year. The theoretical framework that supports it and the design of the didactic sequence itself, designed for future colleagues in training, are presented. Next, we ask ourselves about its relevance, in a new epochal context, such as the post-pandemic, based on the following questions: what temporal categories are essential to learn in initial teacher training, so that later their students are able to understand and interpret the current world and make decisions accordingly?; In times of immediacy and uncertainty, what relevance do present-future relationships have in teacher training and in secondary level classrooms, in which most future teachers will have to work?It is assumed that this article will be a contribution to the training of teachers, at the higher level, and also to other colleagues in Social Sciences, interested in the problem of historical time in school.
La enseñanza de la identidad, desde las localidades a la nacionalidad: el caso de Marcovia en Honduras
Authors: Guevara Pineda Erick José
Published: December 2022

The didactic debates around the “national identity” during the bicentennial established the need to create a project that would establish the basic principles for teaching it. Through an active methodology of the students with the social environment. Some of the original elements of this exercise synthesized in a descriptive narrative evidencing the relevance of dosing identity in the execution of actions for the community. Regarding the valuation of the why? Or what for? It is established that knowledge starts from an action that should not necessarily be memorizing information, on the contrary, linking the student with actors of social relevance, as well as making him/her reflect, question, act, are authentic learning experiences that will finally give him/her the sought-after belonging to a social-human purpose in the same way as its meaning before society.
Reflexiones sobre el impacto de las prácticas discriminatorias en la construcción de la ciudadanía en estudiantes con discapacidad física del Colegio Nocturno de Cartago, Costa Rica

This article aims to reflect on the impact of discriminatory practices in the construction of citizenship in students with physical disabilities at Colegio Nocturno de Cartago, through the application of a workshop. To do this, it incorporated the participants’ experiences within the educational system. Elements such as their daily life, disability, and discriminatory practices that they might live were considered in data analysis. In the methodology, the workshop is divided into a sentence complete activity, and the development of a drawing journal. The results showed that the proposed citizenship from the Ethics, Aesthetics and Citizenship Program works as a homogenizing conceptualization that moves away from the different identities that make up the student community. In addition, the urgency of incorporating aspects such as disability, gender, and discrimination into the study of citizenship construction was evident in the workshop.
CBC Mode of MPF Based Shannon Cipher Defined Over a Non-Commuting Platform Group

Published: December 2022

Commonly modern symmetric encryption schemes (e.g. AES) use rather simple actions repeated many times by defining several rounds to calculate the ciphertext. An idea we previously offered was to trade these multiple repeats for one non-linear operation. Recently we proposed a perfectly secure symmetric encryption scheme based on the matrix power function (MPF). However, the platform group we used was commuting. In this paper, we use a non-commuting group whose cardinality is a power of 2 as a platform for MPF. Due to the convenient cardinality value, our scheme is more suitable for practical implementation. Moreover, due to the non-commuting nature of the platform group, some “natural” constraints on the power matrices arise. We think that this fact complicates the cryptanalysis of our proposal. We demonstrate that the newly defined symmetric cipher possesses are perfectly secure as they were previously done for the commuting platform group. Furthermore, we show that the same secret key can be used multiple times to encrypt several plaintexts without loss of security. Relying on the proven properties we construct the cipher block chaining mode of the initial cipher and show that it can withstand an adaptive chosen plaintext attack.

Hiu Macan 3 surveillance vessel is one of the Directorate General of Marine and Fisheries Resources Surveillance's supervisory vessels which plays an important role in marine surveillance in Eastern Indonesia. In support of monitoring activities, a reliable electrical system is needed and very careful maintenance methods are needed. To support these activities, a generator usage schedule is applied, either during operation or while leaning at the port. The main generator can be used to supply all the ship's electrical needs. The use of the main generator can be optimized to supply all the ship's electricity needs because the daily load percentage is still 33.79%, although this is still within the normal limits. If there is a problem with the main generator, a backup generator can be used, but only for lighting, navigation, and auxiliary engines. The maintenance schedule is required by performing daily, weekly, monthly, and overhaul maintenance. From the analysis carried out, the largest total daily electric power is 41.56 kVA and electrical energy is 310,676 kWh.

Published: December 2022

Abstract The present study was focused on the incidence of ticks and tick-borne diseases (TTBD) in cross-bred cattle (Friesian x Sahiwal) of two farms (n = 2548) in district Lahore, Pakistan. We collected total of 572 ticks (adults and nymphs) and blood samples (10 ml) for microscopic i.e., blood smear test - Giemsa Stain (BST) and molecular analysis; Reverse Line Blot-General Primer-PCR (RLB-PCR) and Specie Specific Primer PCR (SP-PCR) from infested cattle (n = 100) from months of April to September. Results: The tick specie identified was Rhipicephalus microplus at both farms, with significant difference in infestations rate amongst both farms (p< 0.0001). The cross-bred cattle having higher ratio of Friesian blood and lower ratio of Sahiwal blood were mostly infested by ticks (p < 0.0458) and haemoparasites (p <0.474) and vice versa. The SP-PCR showed higher number of haemoparasites infection than BST, which revealed 16% T. annulata (p < 0.0001 and k value 0.485, 0.0001), 51% B. bigemina (p < 0.0001 and k value 0.485, 0.0001) and 15% A. marginale (p < 0.001 and k value 0.207, 0.001), respectively. The single infection with B. bigemina was 34% (n = 34/100) and A. marginale 6% (n = 6/100). The double infection with T. annulata/B. bigemina was 8% (n = 8/100) and B. bigemina/A. marginale 1% (n = 1/100). Whereas the triple infection with T. annulata/B. bigemina/A .marginale was 8% (n = 8/100). The phylogenetic study of isolated sequence of T. annulata revealed close homology to isolates from Iran (87%), B. bigemina to isolates from Cuba (94 to 100%) and A. marginale with isolates from Pakistan (99 to 98%).

Published: December 2022

Abstract The essence of food security centers on ensuring availability and accessibility of foods in adequate amounts and quality for all populations at all times for an active and healthy life. Microorganisms are tiny bioreactors, which represent sustainable resources and promising approaches to bridging the gap between food production and consumption globally via various biotechnological applications. This review focuses on plant-growth promoting bacteria (PGPB) which exert their potential impacts on increasing soil fertility, plant growth, and productivity through a variety of processes, including direct, indirect, and synergistic mechanisms. PGPB plays a substantial role in accelerating nutrients' availability such as (N, P), producing phytohormones such as gibberellins, IAA, and bioactive compounds against biotic and abiotic stressors. Recent advances in PGPB will be addressed as a sustainable approach to satisfy global food demand.

ABSTRACT Objective To evaluate the burden and psychological symptoms of informal caregivers of the elderly during the COVID-19 pandemic. Method Cross-sectional study with 50 caregivers from the Gerontology Outpatient Clinic in the interior of São Paulo, evaluated in 2021 via teleconsultation by the Hospital Anxiety and Depression Scale and the Zarit-Brief Burden Interview. Poisson’s multivariate regression was applied to the two instruments scores according to the set of characteristics of the participants. Results Psychological symptoms were highlighted in caregivers with longer time in exercise (p=0.01; p=0.001) and who lived in the same environment with the elderly (p=0.04; p=0.02). Burden was associated with age (p<0.001) and living with the elderly (p=0.001). Conclusion There is a need for interventions that attenuate psychological symptoms and burden in older caregivers, who live with the elderly and have been working for a longer time.

ABSTRACT The Bacillus thuringiensis bacterium has demonstrated an effective potential in the control of several agricultural pests, among them nematodes. This study aimed to standardize and establish a methodology of bioassays of B. thuringiensis and Meloidogyne incognita with the use of resorcinol, select B. thuringiensis strains toxic to M. incognita in vitro and molecularly identify the presence of the cry6 gene in B. thuringiensis strains. Second-stage juveniles were subjected to resorcinol doses, verifying that the concentration of 0.2 % did not cause mortality and provided the Cry6A toxin ingestion. Thereafter, 16 B. thuringiensis strains were tested in the presence or absence of resorcinol, resulting in mortality rates of 4-36 %. Among the B. thuringiensis strains analyzed for the presence of the cry6 gene, only one was detected (S1617).

Resumo Introdução: A alta taxa de falha na maturação da fístula arteriovenosa é motivo de preocupação para o crescente número de pacientes em hemodiálise. Os fatores não vasculares não foram totalmente estudados em relação ao sucesso da maturação. Métodos: Estudo de coorte prospectivo, observacional de pacientes com DRC diálise ou pré-diálise encaminhados para a primeira criação de fístula arteriovenosa em um centro cirúrgico ambulatorial de Joinville, Brasil, de janeiro de 2021 a julho de 2021. Aspectos antropométricos, características sociodemográficas, comorbidades, além de fatores vasculares verificados pelo ultrassom Doppler. As variáveis associadas à maturação foram analisadas em modelos multivariados por regressão logística. Resultados: Dos 145 pacientes participantes, 88 (60,1%) eram homens, com idade mediana de 59 anos. Houve sucesso na maturação da fístula arteriovenosa em 113 (77,9%) pacientes. Fatores como aumento do IMC, hematócrito, circunferência do braço e valor das dobras cutâneas foram associados a menor chance de maturação da fístula arteriovenosa na análise univariada. Por outro lado, o maior diâmetro da veia e da artéria e fístulas na porção mais proximal do membro superior foram associados a maior sucesso de maturação. Na análise multivariada, tabagismo, maior dobra cutânea e circunferência do braço foram associados a menor chance de sucesso da maturação. O aumento da pressão arterial sistólica e o do diâmetro da veia foram associados a maior chance de sucesso. Conclusão: Além dos aspectos vasculares avaliados pela ultrassonografia Doppler, fatores relacionados à obesidade e/ou a aspectos nutricionais podem influenciar a maturação da fístula arteriovenosa.
Guarani kinship terms with a few twists
Authors: Testa Adriana Queiroz
Published: December 2022

Abstract This article seeks to organize, analyze, and elucidate longstanding gaps and controversies concerning Guarani kinship terminologies. It begins by cross-examining the earliest vocabulary records from the seventeenth century and Lafone-Quevedo’s translation and analyzing these sources, identifying major discrepancies in the latter’s rendition of the originals. This is followed by a review of current research, in which Guarani populations in Argentina, Brazil, and Paraguay are generally divided into distinct subgroups: Kaiowa, Mbya, and Nhandeva. The comparison of their respective terminologies offers a map of missing kintypes, overarching similarities among the three variants, as well as important divergences in nomenclatures identified as pertaining to the same subgroup. In an attempt to track some of the missing pieces to this kinship puzzle, new data on the Mbya terminology, acquired by combining ethnographic research and computational methods, establishes a complete set of kintypes, including those applied to distant genealogical positions. This terminology reveals generational skews that connect it to the seventeenth-century Guarani vocabulary, recuperating historical ties that were previously untraced, and elucidates divergences in the Kaiowa nomenclature. The article concludes that the Mbya and Kaiowa share the same semantic kinship structure, undeniably of the Iroquois type, challenging the prevailing tripartite divide.

Abstract Introduction Pain is one of the main symptoms prevalent in most pathologies. Transcutaneous Electrical Nerve Stimulation (TENS) represents not only a therapeutic measure, but also a mean to quantify the neurosensory and pain perception in patients with chronic pain. Objective To evaluate the relationship between sex and age with neurosensory thresholds (sensory threshold and tolerance threshold) in the application of therapeutic current in patients with chronic pain. Methods Forty-five patients with chronic pain (30 women and 15 men) aged between 24 and 87 years were selected. Each patient answered the Individual Questionnaire, McGill Pain Questionnaire (MPQ) and Beck Depression Inventory (BDI). Subsequently, the electric current was applied, through which the sensory and pain thresholds were analyzed, as well as the perception of activation of the neurosensory pathways for each individual. Data were analyzed using the SPSS 24.0 for Windows. Results There was no significant correlation (p > 0.05) between a possible depressive diagnosis and the perception of current by the sensory and pain thresholds. Regarding sex, there was a significant difference in sensory thresholds (p = 0.003) between men and women, while no statistical differences were observed between sexes for pain complaint and pain threshold (p > 0.05). For the correlational analysis, a significant correlation (p = 0.05) was identified between the variables BMI and pain tolerance threshold (r = 0.68) for females and age and sensory threshold (r = 0.65) for males. Conclusion The sex and age variables are important in the measurement of TENS parameters because they lead to significant differences in sensory and pain thresholds.

RESUMO O estado de Minas Gerais é o maior produtor de minério de ferro e, consequentemente, de rejeito de minério de ferro (RMF) do Brasil. Esta atividade de grande impacto ambiental está no centro das discussões políticas e sociais atuais devido aos desastres com rompimento de barragens ocorridos nas cidades de Mariana (2015) e de Brumadinho (2019), ambas mineiras. Estes eventos põem em discussão os métodos de descarte do RMF e coloca em destaque a possibilidade de um uso mais sustentável para este resíduo. Uma das alternativas é a utilização do RMF como insumo na fabricação de componentes da construção civil. Este trabalho avaliou a viabilidade do uso de RMF como agregado miúdo em microconcretos para a produção de elementos vazados. Para isso, o RMF foi caracterizado por meio de ensaios físicos e químicos. A dosagem do microconcreto foi realizada com base no método ABCP com fc28 = 25 MPa e abatimento do tronco de cone entre 80 e 100 mm. Para a análise mecânica do microconcreto, foram moldados corpos de prova (10x20 cm) cilíndricos e realizados ensaios de resistência à compressão, absorção e índice de vazios, após 28 dias de cura. Para obter parâmetros de durabilidade, foram realizados ensaios de carbonatação natural aos 60, 120 e 180 dias, carbonatação acelerada aos 28 e 56 dias (teor de CO2 = 5%; Umidade Relativa = 65%), além de ensaio de ataque ácido (solução H2SO4 a 5%). O estudo apontou para a viabilidade da substituição do agregado miúdo por RMF na produção de microconcretos para elementos vazados, sem prejuízo para a sua durabilidade.
DESIGN AND IMPLEMENTATION OF EFFICIENT DIGITAL FILTERS USING LABVIEW
Authors: Dondapati Naresh
Published: December 2022

In digital signal processing, the purpose of a filter is to remove unnecessary components in the signal, such as random noise. An infinite impulse response (IIR) filter is an iteration-type filter. The current pattern resulting from the IIR filter is based on the current input and output patterns. Several methods are available to detect digital IIR filters. Filters are widely used in signal processing and communication device approaches such as in channel equalization; noise reduction; radar systems; audio, speech signal, video, and biomedical signal processing, and economical, electrocardiogram, electroencephalogram, electromyography, and electrical circuit analyses. In this study, we used the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software program to analyze the design and implementation of an efficient digital filter, the results of which are presented in this paper. The important objective of this task was to design and examine different IIR filters-namely, Chebyshev, Butterworth, and Elliptic filters-using LabVIEW for the simulation processes. LabVIEW is used by graphical programming environmental engineers to implement automated research, certification, and product testing systems. In this work, the LabVIEW graphical programming tool was used because it gives accurate results in real time compared to other available simulation tools.
Rendaku is not blocked by two nasal consonants: A reply to Kim (2022)
Authors: Kawahara Shigeto , Kumagai Gakuji
Published: December 2022

Rendaku is a morphophonological process in Japanese, in which the first consonant of the second element of compounds becomes voiced (e.g. /ao-sora/ → [ao-zora] ‘blue sky’). In a recent paper, Kim (2022) argues that the presence of two nasals—but not one nasal— in the second element reduces the probability of Rendaku application (e.g. /umi-kamome/ → [umi-kamome], *[umi-gamome] ‘seagull’). This claim has an important consequence for grammatical theories, as it would constitute a case in which the influences of two segments add up to block a phonological process, a pattern that is referred to as “super-additive counting cumulativity.” We have reexamined the empirical basis of this claim, and have found that there are only four relevant lexical items. Moreover, two of these items actually undergo Rendaku almost all the time, and there are thus only two items whose Rendaku is clearly blocked. The empirical basis of the theoretical claim based on Rendaku thus seems to be weak at best. With this, we move on to the main contribution of this paper, which is a new nonce-word experiment that aimed to resolve the conflicting results from the previous studies on this topic. The results of the current experiment show that the applicability of Rendaku is not reduced by the presence of two nasal consonants.

The research described here was aimed at illuminating the variation in the strengthening mechanism of Cr15Ni5 precipitation hardening stainless steel (15-5PH stainless steel) processed at aging temperatures ranging from 440–610 °C. The variation in the tensile property corresponding to different aging processes was measured, and the microstructure features were further characterized using a transmission electron microscope (TEM) and electron back-scatter diffraction (EBSD). Results indicated that the strength contribution induced by grain-refinement strengthening, precipitation strengthening and dislocation strengthening corresponding to different aging temperatures varying from 470–610 °C were determined to be distributed in strength ranges of 296–345 MPa, 0–469 MPa and 97–803 MPa, respectively. The strength increments caused by different combinations of precipitation strengthening and dislocation strengthening were crucial for determining the final mechanical properties of the studied 15-5PH stainless steel.
