Authors: Manfrini Gisele Cristina , Heidemann Ivonete Teresinha Schülter Buss , Costa Francisco da Silva , Silva Harrysson Luiz da , Lopes Sara Mendes Boeira
Published: July 2023

Resumo O artigo tem como objetivo compreender os impactos psicossociais vivenciados por trabalhadores de saúde após situação de desastre no estado de Santa Catarina, na região Sul do Brasil. Para tal, realizou-se estudo qualitativo de múltiplos casos e entrevistas narrativas com profissionais de serviços de saúde mental, atenção primária à saúde e gestores municipais em Itajaí, Blumenau e Rio do Sul. A análise das narrativas seguiu as etapas do método de Fritz Schütze. Descreveram-se os impactos psicossociais sobre a saúde e o trabalho dos entrevistados, afetados direta e/ou indiretamente pelo desastre natural ocorrido em 2008 na região, e subsequentes eventos de menor intensidade. Nos três casos, os impactos foram percebidos semelhantemente, ainda que as consequências do evento na rede municipal tenham sido enfrentadas de formas diferentes em cada localidade. Os resultados revelam a importância da promoção da saúde no trabalho e do desenvolvimento de habilidades pessoais, a resiliência frente a situações adversas e a necessidade de educação contínua e permanente.
Daily care in the life of female relatives of children attended in a CAPSi in Santos
Authors: Bisi Carolina Claudio , Nakamura Eunice
Published: July 2023

Abstract Children’s mental health has gained notorious space in Brazilian and international research. It’s known that childcare, besides requiring certain specificities, requires a consolidated support network, and one of these caregivers is the family. In the care provided by the family, a process of feminization is noticed: mothers, grandmothers, sisters, or other family members are markedly more present in groups for family members offered by the CAPSi (Children’s Psychosocial Attention Center). This article presents some results of a scientific initiation research, whose objectives were to identify and understand which are the daily care practices performed by women family members, caregivers of children assisted in a CAPSi in the municipality of Santos and the support received inside and outside the service. The qualitative research used as technique in-depth interviews, with semi-structured script, carried out by telephone, for listening to these women, identified from the information given by professionals of the service. In the women’s reports, we identified native categories related to care: routine, normal, and support. These categories were mentioned by the women to define the daily care of the children. We noticed that the daily routine of care characterizes it as “normal” for these women, and is not considered a burden in their lives or even problematized.
Usos y apropiaciones del sistema de salud privado por parte de los migrantes chinos en Argentina
Authors: Incaurgarat María Florencia
Published: July 2023

Resumen El presente artículo aborda las formas de apropiación de los migrantes chinos respecto al sistema de salud argentino, haciendo hincapié en el sistema privado en contraposición al de salud pública. Este caso se enmarca en un trabajo de campo etnográfico multisituado realizado con migrantes chinos principalmente en la ciudad de Mar del Plata, pero también en la ciudad de Buenos Aires. También una estancia de investigación realizada en la ciudad de Hangzhou, provincia de Zhejiang, China, posibilitó dar cuenta de las formas de apropiación del sistema de salud local en el país de origen. En suma, aquí se retrata una baja apropiación general del sistema de salud local por parte de los migrantes, tanto público como privado, salvo en el caso de urgencias, primando la autoatención al interior del grupo del grupo migrante. La diferenciación en los usos y apropiaciones del sistema de salud público y privado reside en que se acude al primero prioritariamente para acciones de prevención primaria como son los controles del desarrollo infantil y del embarazo, como así también para padecimientos menores. Por el contrario, los migrantes suelen recurrir al sistema de salud privado ante casos de mayor complejidad y gravedad, mostrando una priorización del uso del tiempo bajo una lógica de costo-beneficio.
Wild, Indigenous, Lame, Invalid: Anti-Ableist Epistemologies of the South
Authors: Pino-Morán Juan Andrés , Rodríguez-Garrido Pía , Lapierre Michelle
Published: July 2023

Abstract The aim of the article was to present a first approach to an epistemological proposal that reflects on and deals with the construction and legitimation of knowledge generated from abject, abnormal, or crippled corporeities geopolitically located in the South. It pays special attention to the sex-gender-ability system in the social and epistemological organization of knowledge. In this development, we identify a positionality and wasted wealth for regional social analysis and transformation as a result of a modern colonial order. Hence, this proposal is inscribed within the Latin American critical thinking to reflect on those other places of abject enunciation.
A influência dos determinantes sociais na vida de mulheres negras no Centro de Atenção Psicossocial do tipo álcool e outras drogas em Caucaia, Ceará
Authors: Azevedo Uly Castro de , Gomes Daiane Daine de Oliveira
Published: July 2023

Resumo O objetivo deste artigo é analisar os determinantes sociais de saúde que incidem na vida das mulheres negras em acompanhamento biopsicossocial no Centro de Atenção Psicossocial (Caps), do tipo álcool e outras drogas (AD), em Caucaia, Ceará. Trata-se de um estudo qualitativo, com coleta de dados realizada através de entrevistas semiestruturadas e análise realizada por meio da análise de conteúdo de Bardin. Utilizou-se da pesquisa bibliográfica, documental e de campo. Buscou-se identificar como se dá o acesso dessa população ao direito à saúde e analisar possíveis implicações de ser mulher negra e fazer uso de álcool e/ou outras drogas. Como resultado, foi possível perceber que esse grupo populacional tem maiores dificuldades para realizar o tratamento especializado, por conta do racismo institucional, por sofrerem uma forte pressão social para evitar o acompanhamento e ainda por serem as responsáveis, em sua maioria, pelos cuidados materno-familiares - tarefas domésticas, cuidar de filhos e companheiro(a).
Uma cidadania da fertilidade - as políticas de saúde da mulher como tecnologias de produção do sexo e do gênero
Authors: Rosa Hevelyn , Cabral Cristiane da Silva
Published: July 2023

Resumo Este artigo analisa como as principais políticas públicas brasileiras de saúde da mulher, desde 2000, definem e caracterizam seu público-alvo. Marcando uma articulação entre distintos conjuntos de agentes, campos disciplinares e tecnologias de governo, as políticas operam representando e conformando o sujeito a quem se destinam. No campo da saúde da mulher, essa operação também é viabilizada mediante a modulação do sexo e do gênero, especificamente a reiteração de códigos responsáveis por designar a “natureza” da mulher. Trata-se de uma pesquisa documental realizada através da perspectiva antropológica de análise de documentos, que investigou as peças documentais da Política Nacional de Atenção Integral à Saúde da Mulher (2004), da Rede Cegonha (2011) e documentos correlatos. Os temas da fertilidade e da reprodução têm se mostrado persistentes no conjunto de ações em saúde da mulher, formando os núcleos que concentram esforços e verbas estatais. A mulher constituída pelas políticas de saúde tem maiores chances de acessar seus direitos de cidadania por meio de sua função como potencial reprodutora. Identifica-se a complexidade da construção de um sujeito de direitos, mesmo quando esteve imbuída de um certo ideário emancipatório, presente nos interstícios do Estado.

Published: July 2023

RESUMO Estações de tratamento de esgoto (ETE) com processos anaeróbios estão consolidadas na América Latina. Suas diversas características favoráveis tornam-nas uma opção atrativa para regiões de clima quente, mas existem ainda restrições, como as relacionadas às emissões gasosas difusas. Nesse contexto, o presente trabalho objetivou o desenvolvimento da ferramenta computacional Balanço de Energia e Carbono em ETE Anaeróbias (BECarbon0), com base na compilação, em planilha eletrônica, de equações e coeficientes da literatura especializada, que permite comparar diferentes cenários e alternativas tecnológicas para o manejo de emissões gasosas em ETE que empregam reatores anaeróbios de fluxo ascendente e manta de lodo (UASB). Possibilita-se assim que projetistas e tomadores de decisão avaliem aspectos de recuperação de energia e gestão da pegada de carbono. Por fim, apresenta-se um estudo de caso fictício com três cenários cujos resultados apontam para a possibilidade de redução da pegada de carbono total da ETE em 82% se comparada à configuração normalmente adotada no Brasil.
Brightness of point application of fluorescent quinine tracer for surface waters
Authors: de Lima João Luís Mendes Pedroso , Zehsaz Soheil , Tavares Jean Leite , de Lima Maria Isabel Pedroso
Published: July 2023

Abstract Fluorescent tracers have been widely used in hydrology. Recently, quinine started to be used as a fluorescent tracer for estimating the velocity of surface sheet flows over various soil surface conditions and environments. In the present work, the visibility of the fluorescent tracer (quinine) was assessed for various applications’ forms of the tracer (liquid, ice cube with quinine and soaked sponge). The brightness intensity of all tracer forms was estimated for different hydraulic conditions (hydrostatic, linear, and rotational flows) and for clear water, and water with medium and high suspended sediment loads. Results show that, when used as a flow velocity tracer, liquid quinine solution has to be applied carefully into the water and should better be used on sheet flows, shallow overland flows or shallow still waters. Its visibility in deep and muddy flows is insufficient for surface velocity estimations. The sponge soaked with quinine solution, which partially floats, is better visible in clear waters or low-medium suspended sediment loads, regardless of the water depth. However, for high turbulence and rotational flows, the soaked sponge sinks and is no longer visible. The ice cubes showed better visibility in all tested flow water depths and suspended sediment loads, although, in very shallow depths (of millimetres), ice cubes cannot be used because they might not follow adequately the fluid motion, which also applies to the sponge.
As práticas letivas na educação física durante a pandemia: expectativas e realidades ,
Authors: Silva Nuno Miranda e , Dinis Sónia Pereira
Published: July 2023

Resumo As restrições da pandemia desafiaram as caraterísticas de proximidade e contacto físico da Educação Física (EF), o que poderá ter levado à reinvenção da disciplina. Contudo, no contexto português, temos pouco conhecimento da medida dessas limitações, em particular na relação de interdependência entre as práticas letivas de ensino, avaliação e aprendizagem. E a reconfiguração dessas práticas não nasceu do vazio, mas decorreu de expectativas de entidades a montante, que afetaram a ação dos docentes. Porém, também se conhece pouco acerca da relação entre esse aconselhamento e a realidade do terreno, em face ao que estava previsto nos programas para condições de normalidade. Esse conhecimento será relevante para a intervenção e intencionalidade educativa do pós-pandemia e, no objetivo de preencher este vazio, implementamos uma investigação para aceder às práticas letivas de ensino, avaliação e aprendizagem aconselhadas pelas entidades representativas da EF e adotadas pelos professores, em função do período pandémico. Inscreve-se no paradigma interpretativo, com abordagem qualitativa e na modalidade de estudo interpretativo de base, com os dados recolhidos por análise documental e entrevista com guião semiestruturado e tratados por análise de conteúdo. Os resultados sugerem que as práticas letivas foram desagregadas e perderam reciprocidade; e que as expectativas das entidades foram desajustadas face às necessidades dos professores no contexto. Assim, a EF, sensível à situação pandémica, dessensibilizou-se, devido à perda de relações entre o ensino, a avaliação e a aprendizagem; e desprojetou-se, porque perdeu elementos do seu projeto curricular e a sua projeção educativa; o que pode contribuir para consolidar a marginalização da EF e aconselha à reconexão entre o ensino, a avaliação e a aprendizagem.
Incorporating symmetrical and asymmetrical dispersal into Ecological Niche Models in freshwater environments
Authors: Parreira Micael Rosa , Tessarolo Geiziane , Nabout João Carlos
Published: July 2023

Abstract: Aim Ecological niche models (ENMs) are based mainly on environmental (mostly climatic) and occurrence data to predict the potential distribution of species. In freshwater habitats, species dispersal is not restricted only by physical barriers but also by the directional movement of the hydrographic network, which can be considered through spatial predictors. Here, we aim to evaluate the effect of including asymmetrical and symmetrical spatial predictors in the potential geographic distribution of a freshwater fish in the Tocantins-Araguaia River basin, Brazil. Methods For this, we built models with seven variable sets representing the climatic and spatial models, as well as their interactions. Results We found that the overall best models (higher evaluation and lower variation among modeling methods) are those built using AEM (asymmetrical dispersal [i.e., dispersal along the river flow path]), either alone or in combination with environmental variables (ENV). Moreover, the inclusion of asymmetrical dispersal variables, taking into account dispersal limitations of species, decreased the overprediction to climatically suitable but disconnected areas through rivers. Conclusions Therefore, future ENM studies, especially those using species groups with directional dispersal, should consider the inclusion of asymmetrical spatial predictors to increase the model’s accuracy and ecological reality.

Published: July 2023

Agricultural waste shows promise for use in lightweight building materials. The combination of a geopolymer and wheat straw (WS) is adopted to produce a kind of eco-friendly lightweight composite. Using WS pretreated with sodium hydroxide (NaOH) and sodium metasilicate (Na2SiO3) solutions, the influence of WS on the properties of the geopolymer–WS composite (GWSC) is investigated. The pretreated WS avoids the retarding effect of the untreated WS on the hydration of the geopolymer and even presents an accelerating effect. Increasing the content of pretreated WS generally results in a reduction in apparent density and strength. A GWSC with an apparent density of 1000–1500 kg/m3 can be prepared, corresponding to a 28-day compressive strength between 5 and 25 MPa. The water absorption linearly increases with the increase in the pretreated WS content, while an appropriate amount of the pretreated WS can enhance the water resistance of the GWSC. A WS/fly ash ratio lower than 8% can produce a GWSC with qualified thermal insulation performance. Alkaline treatment, particularly sodium hydroxide treatment, significantly improves the bonding strength between the fiber and the geopolymer matrix. In addition, pretreated WS saturated with sodium hydroxide and sodium metasilicate solutions is beneficial to the fluidity of the geopolymer–WS mixture and could act as an internal curing agent for enhancing the hydration of the geopolymer.

Published: July 2023

Bamboo is a naturally sustainable material that has been used in construction for a very long time. Investigations on the feasibility of using bamboo for reinforcing concrete have been carried out by various researchers. However, the lack of construction codes and design procedures for bamboo-reinforced concrete (BRC) structures is preventing structural engineers and construction firms from using bamboo in construction. The aim of this work was therefore to review various BRC structural elements, including beams, columns, slabs and walls, in order to develop guidelines for using them confidently.

As a high-contact service sector with limited capacity for remote work, the US leisure and hospitality sector—which includes restaurants, bars, hotels, museums, and movie theaters—was hit particularly hard by the COVID-19 pandemic. In the first two months of the pandemic, leisure and hospitality lost over 8 million jobs, nearly half its employment (Figure 1, solid red line).
Your Friends, Your Credit: Social Capital Measures Derived from Social Media and the Credit Market
Authors: Bricker Jesse , Li Geng
Published: July 2023

Chetty et al. (2022a) introduced an array of social capital measures derived from Facebook friendships and found that one of these indicators, economic connectedness (EC), predicted upward income mobility well. Bricker and Li (2017) proposed the average credit score of a community's residents as an indicator of local social trust. We show in this paper that the average credit scores are robustly correlated with EC, negatively correlated with the friending-bias measure introduced in Chetty et al. (2022b), and predict economic mobility to a comparable extent after controlling for EC. The consistency and complementarity between these two indicators, despite being derived from individuals' activities in distinct contexts, underscore trust as a crucial component of social capital and provide insights that are useful for understanding the formation and accumulation of social capital.
Why Does the Yield Curve Predict GDP Growth? The Role of Banks
Authors: Minoiu Camelia , Schneider Andres , Wei Min
Published: July 2023

We provide evidence on the effect of the slope of the yield curve on economic activity through bank lending. Using detailed data on banks' lending activities coupled with term premium shocks identified using high-frequency event study or instrumental variables, we show that a steeper yield curve associated with higher term premiums (rather than higher expected short rates) boosts bank profits and the supply of bank loans. Intuitively, a higher term premium represents greater expected profits on maturity transformation, which is at the core of banks’ business model, and therefore incentivizes bank lending. This effect is stronger for exante more leveraged banks. We rationalize our findings in a portfolio model for banks.
Rusya'nın Orta Doğu Politikası: Putin Dönemi
Authors: YALÇINKAYA Alaeddin , DOĞAN Soner
Published: July 2023

Rusya, Sovyetler Birliği dağıldıktan sonra iç sorunlarla uğraştığı için Orta Doğu başta olmak üzere küresel sorunlara yeterli ilgiyi gösterememiştir. 2000’li yıllarda iktidarı ele geçiren Vladimir Putin, ülke içerisindeki sorunları kısa süre içerisinde çözerek, Rusya’nın SSCB dönemindeki etkinliğine ulaşması için dış politikada aktif arayış içerisinde olmuştur. Amerika’da yaşanan 11 Eylül saldırıları nedeniyle uluslararası arena da kaos durumunun ortay acıkmasıyla Putin, eski Sovyet Cumhuriyetleri başta olmak üzere SSCB’nin nüfuz kurduğu ülkeler ile ikili ilişkileri yeniden canlandırmaya başlamıştır. Putin, SSCB’nin yıkılmasıyla başlayan ABD’nin tek kutuplu süper güç modelini etkisiz hale getirmek ve Rusya’nın yeniden süper güç olduğunu hatırlatmak için çevre ülkelerde askeri operasyonlara başlamıştır. Bu kapsamda 2008 Gürcistan müdahalesi ve 2014’te Kırım'ın işgal edilmesi ile somut adımlar atmaya başlamıştır. Putin’in Orta Doğu politikası, Sovyetleri dönemindeki etki alanını genişletmek ve pasifleşen ilişkilerin yeniden canlanması için aktif diplomasi atağı başlatmıştır. 2011 yılında başlayan Arap Baharı olayları ile Rusya, Suriye, Mısır, Irak, Libya ve Körfez ülkeleriyle ikili ilişkileri yakınlaştırmıştır. Rusya’nın bu ülkelerde iktidardaki isimleri desteklemesi, ilgili devletler tarafından memnuniyetle karşılanmış ve ikili ilişkilere pozitif katkı sağlamıştır. Bu durum ise Putin’in Orta Doğu’daki nüfuzunu güçlendirmiştir. Bu çalışmada Putin'in Orta Doğu'da yeniden etkinlik kurma politikası incelenmiştir. Rusya’nın yakın çevre politikasını güçlendirdikten sonra Orta Doğu'da siyasi, askeri ve ekonomik etkinliğini geliştirmesi, yeni üsler kurması, vekâlet savaşları veya doğrudan müdahalelerle yeni dönemin belirleyici aktörleri arasına girmesi, öncelikle Sovyet sonrası Avrasyacı yaklaşımın genişletilmesi olarak değerlendirilmektedir. Jeopolitik avantajlarını bu süreçte ustaca kullanan Putin Rusya’sının stratejik dönüşümü, Realist büyük güç politikasını yeniden gündeme getirdiği sonucuna varılmaktadır.

Published: July 2023

Сrystal structure, piezoelectric and magnetic properties of solid solutions BiMn1-xFexO3 (x ≤ 0.4) prepared by solid-phase reactions from a stoichiometric mixture of simple oxides at high pressures and temperatures have been studied. The structure of the compounds is characterized by the concentration driven phase transition from the monoclinic structure to the orthorhombic structure at x ≈ 0.2; wherein the ordering dz2 of the orbitals of Mn3+ ions is destroyed, and the inhomogeneous magnetic state is stabilized. Solid solutions with 0.2 ≤ x ≤ 0.4 are characterized by a nonzero piezoelectric response, wherein both ferroelectric and magnetic domain structures exist, the ferroelectric switching voltage decreases with an increase of iron ions concentration, while the residual magnetization value decreases. The maximum value of the piezoresponse signal is observed in the compound BiMn0.7Fe0.3O3. The work clarifies the relationship between the chemical composition, the crystal structure, piezoelectric and magnetic properties of solid solutions BiMn1-xFexO3. The presence of both magnetic and electric dipole ordering indicates the perspectives for the practical usage of such materials.

The inability of organic coagulants to purify potable water to its best attainable quality
Authors: P Polasek  , CJ Wantenaar
Published: July 2023

Organic coagulants have gained increasing popularity over the past 30 years because they are considered cheaper and more user-friendly than traditional mineral hydrolysing coagulants. Regrettably, in-depth studies have not yet been conducted on their ability to purify water to a healthy palatable drinking quality which is risk-free for lifetime consumption in terms of the national standard for drinking water quality of various countries worldwide, and does not become a source of secondary pollution in the reticulation system. The objective of this paper is to provide information about the natural organic matter (NOM) removal efficiency attained at different waterworks purifying water with different organic coagulants, and to compare this with that attained using mineral coagulants. The findings presented in this article prove that organic coagulants are not an equivalent replacement for mineral coagulants, as the purified water is of an inferior quality which does not comply with the limits set by national standards of different countries worldwide.
Relationships between reference site quality and baetid mayfly assemblages in mountainous streams of the Luvuvhu catchment, South Africa
Authors: Pfananani Ramulifho  , Nick Rivers-Moore  , Stefan Foord
Published: July 2023

With water quality deteriorating rapidly at a global scale, river sections suited to serve as reference sites are being increasingly lost. It thus becomes critical to develop rapid methods to confirm that previously monitored sites continue meet the requirements of reliable reference sites. In the absence of pristine sites, 9 near-natural sites, as defined by the Kleynhans (1996) classification, were used as reference sites for the Luvuvhu River catchment to compare the quality of physico-chemical factors against a biological metric. Baetid mayfly community structure at a site was chosen as an index of water quality, since this family is common in all types of freshwaters, highly diverse and adapted to unpolluted running water. Baetid larvae were sampled monthly from stones-in-current biotopes across 9 sites for over 1 year, between December 2016 and January 2018. A Spearman’s correlation test was used to evaluate the relationship between physico-chemical factors and identify redundant variables. Water quality standards were measured against the national water quality guidelines for aquatic ecosystems. We used a generalized linear model to determine the effect of physico-chemical variables on baetid species, and canonical correspondence analysis to show the relationships between baetid species, sites, and physico-chemical variables. A total of 3 039 individuals belonging to 12 mayfly species were recorded. Our findings indicated that while the physico-chemical factors were highly variable, they were within favourable ranges to reflect reference site conditions. While water temperature was the most important driver of baetid community structure in general, as it negatively affected their abundances, a subset of species (Pseudoponnota sp., Pseudocloeon sp., Acanthiops varius and Demoulinia crassi) showed clear responses to changes in TDS and stream width. We conclude that specific baetid species show good potential as biological indicators of reference sites and chronic water temperature stress, making assessment of reference sites easier.
Workplace and non-workplace cannabis use and the risk of workplace injury: Findings from a longitudinal study of Canadian workers
Authors: Carnide Nancy , Landsman Victoria , Lee Hyunmi , Frone Michael R. , Furlan Andrea D. , Smith Peter M.
Published: July 2023

Objectives

Findings of previous studies examining the relationship between cannabis use and workplace injury have been conflicting, likely due to methodological shortcomings, including cross-sectional designs and exposure measures that lack consideration for timing of use. The objective was to estimate the association between workplace cannabis use (before and/or at work) and non-workplace use and the risk of workplace injury.

Methods

Canadian workers participating in a yearly longitudinal study (from 2018 to 2020) with at least two adjacent years of survey data comprised the analytic sample (n = 2745). The exposure was past-year workplace cannabis use (no past-year use, non-workplace use, workplace use). The outcome was past-year workplace injury (yes/no). Absolute risks and relative risks (RR) with 95% confidence intervals (CIs) were estimated between workplace and non-workplace cannabis use at one time point and workplace injury at the following time point. Models were adjusted for personal and work variables and were also stratified by whether respondents’ jobs were safety-sensitive.

Results

Compared to no past-year cannabis use, there was no difference in workplace injury risk for non-workplace cannabis use (RR 1.09, 95%CI 0.83–1.44). However, workplace use was associated with an almost two-fold increased risk of experiencing a workplace injury (RR 1.97, 95%CI 1.32–2.93). Findings were similar for workers in safety-sensitive and non-safety-sensitive work.

Conclusion

It is important to distinguish between non-workplace and workplace use when considering workplace safety impacts of cannabis use. Findings have implications for workplace cannabis use policies and substantiate the need for worker education on the risks of workplace cannabis use.
RNA extraction and quantitative PCR to assay inflammatory gene expression v1
Authors: HARDING OLIVIA
Published: July 2023

Real-time quantitative PCR (RT-qPCR) is a sensitive assay to determine the production of selected mRNA transcripts in various conditions. We required such an assay to demonstrate the effects of mitochondrial depolarization in the presence of Parkin, since we found that damaged mitochondria recruited the NF-kB effector complex molecules, NEMO and IKKb. We developed this protocol to test levels of NF-kB response genes in a cell model transiently over-expressing Parkin. With this technique we found significant upregulation of key pro-inflammatory genes normalized to a housekeeping gene, Gapdh.
Assessment of prepulse inhibition (PPI) of the acoustic startle reflex in rodents v1
Authors: Kich Giongo Franciele
Published: July 2023

The acoustic startle reflex is an automatic and involuntary response that occurs in humans and other animals when they are exposed to sudden and intense acoustic stimuli, such as loud noises. This response can be influenced by several factors, including the intensity and timing of the stimulus, the individual's state of alertness, and contextual factors. It can also be modulated by prior exposure to a weak prepulse shortly before the startling stimulus, a phenomenon known as prepulse inhibition (PPI). PPI reflects the brain's ability to filter out irrelevant or non-threatening sensory information, and is considered an important indicator of sensorimotor gating. In individuals with schizophrenia, both the startle response and prepulse inhibition are disrupted, which is believed to result from alterations in glutamatergic and dopaminergic neurotransmission. These deficits in sensorimotor gating may lead to sensory overload and the misinterpretation of sensory information. Here we describe a protocol to measure PPI in mice and rats using a startle chamber from Insight®️ (SP, Brazil).
