Predictions from standard epidemiological models of consequences of segregating and isolating vulnerable people into care facilities
Authors: Hickey Joseph , Rancourt Denis G.
Published: October 2023

Objectives

Since the declaration of the COVID-19 pandemic, many governments have imposed policies to reduce contacts between people who are presumed to be particularly vulnerable to dying from respiratory illnesses and the rest of the population. These policies typically address vulnerable individuals concentrated in centralized care facilities and entail limiting social contacts with visitors, staff members, and other care home residents. We use a standard epidemiological model to investigate the impact of such circumstances on the predicted infectious disease attack rates, for interacting robust and vulnerable populations.

Methods

We implement a general susceptible-infectious-recovered (SIR) compartmental model with two populations: robust and vulnerable. The key model parameters are the per-individual frequencies of within-group (robust-robust and vulnerable-vulnerable) and between-group (robust-vulnerable and vulnerable-robust) infectious-susceptible contacts and the recovery times of individuals in the two groups, which can be significantly longer for vulnerable people.

Results

Across a large range of possible model parameters including degrees of segregation versus intermingling of vulnerable and robust individuals, we find that concentrating the most vulnerable into centralized care facilities virtually always increases the infectious disease attack rate in the vulnerable group, without significant benefit to the robust group.

Conclusions

Isolated care homes of vulnerable residents are predicted to be the worst possible mixing circumstances for reducing harm in epidemic or pandemic conditions.
Abstract 6306: Genomic analysis markers of stemness in oral cancer progression
Authors: Unger Gretchen , Wuertz Beverly G , Gaffney Patrick , Ondrey Frank G
Published: October 2023

Introduction: In clinical cancer treatment there is an continuing effort to identify limited gene sets from high dimensional data to predict risk, treatment response, etc. Oral carcinogenesis is a multistep process of mutations, disordered growth, and the development of invasion. In the oral cancer milieu, inflammation and stemness has been demonstrated to be cooperative during carcinogenesis. We hypothesized that differences in inflammation, stemness, and EMT might distinguish lesion and adjacent normal mucosa in our RNA Seq data on preneoplastic lesions. Once candidate genes are identified they might be applied to other oral mucosal specimens to identify risk for malignancy development.

Materials and Methods: We collected lesion and adjacent normal mucosal tissues from 16 subjects with high risk leukoplakia and early oral cancer (T1N0 and T2N0). Sequencing libraries were generated using the Illumina Truseq Stranded mRNA library prep kit. Sequencing was performed on an Illumina Hiseq 3000 instrument with paired-end 75bp read and sequenced to an overall depth of 30 million reads per sample.

Results: After developing a biospecimen collection procedure that functions in the senior author’s clinic flow, we were able to isolate sequenceable total RNA from 100% of the specimens we collected. We identified several hundred differentially expressed genes between lesion and adjacent normal. With regard to stemness, inflammation, and EMT we multiple candidate genes that could be incorporated into a limited gene set for further studies. Aldehyde dehydrogenase family members were of particular interest in the stemness candidate genes, for example. ALD 1A1 and ALD 3B1, were significantly upregulated in lesion versus normal (P< 0.02).

Conclusions: We conclude there are differentially expressed inflammatory, EMT, and stemness in oral preneoplastic specimens. We have identified multiple candidate genes that could be assembled into a limited gene panel (12-24 genes) for further studies of oral cancer risk in mucosal lesions

Published: October 2023

Laboratory skills are an important aspect of natural sciences in schools and higher education, often linked to psychomotor aspects of learning. Several studies have developed several methods that can be used to evaluate laboratory skills, for example, the use of observation sheets equipped with rubrics. However, often using this method requires a longer learning time. Therefore, there is a need for research that examines how to evaluate students' basic laboratory skills. This research aims to analyze students' basic laboratory skills using pictorial-based instruments. This research method uses descriptive qualitative. This instrument is equipped with pictures that provide visualization. The basic laboratory skills are focused on experiments on making standard solutions from solids, making standard solutions from concentrated solutions, and acid-base titrations. Based on the analysis, it was found that the basic laboratory skills of science students in the experiment of making standard solutions from solids contained six basic skills, including selecting tools, weighing solids, transferring solids into a beaker, putting them in a volumetric flask, marking the solution, reading the meniscus mark. In the experiment of making a standard solution, there are five basic skills, namely selecting tools, taking the stock solution, transferring it into a volumetric flask, marking the solution, and reading the meniscus mark. The titration experiment consists of 8 skills, including selecting equipment, taking the analyte solution, taking the titrant solution, adding a titration indicator, using the titration technique, observing the endpoint of the titration, reading the meniscus, and calculating the solution's concentration.

The dwindling availability of land has resulted in an increase in the price of residential houses every year, moreover cities with relatively denser populations have an increase in house prices of more than 20% each year. The design of residential houses by utilizing used containers will save material, transportation, and construction costs, so it is hoped that this alternative can be developed to become a sustainable solution. The research was conducted by designing a 2-storey container house with a building area of 172.8 m2 using the SketchUp2022 software and then calculating the estimation cost analysis. The results of the estimation costs show that conatainer house needs cost of IDR 565,476,007.90 or IDR 2,827,380.04/m2 included tax.  So that container house can savings of 19.22% - 43.45% when compared to the average price of conventional houses in Indonesia of IDR 4,500,000.00 - IDR 6,000,000.00 per m2 .

Published: October 2023

During the current administration, the construction sector, especially toll road infrastructure in Indonesia, has increased. This will increase the amount of cement production to meet construction needs. Even though the cement industry is one of the contributors to gas emissions. In addition, the plantation sector can be optimized as an alternative construction material. Such as palm shell waste (POFA), which contains the same content as cement. The fisheries sector can also be optimized as an alternative construction material. such as green mussel shells which have the same content as cement, which is pozzolanic. Based on these problems, the purpose of this research is to optimize palm oil shell waste and green mussel shells as cement substitution materials in CTB to reduce gas emissions. The method used is research and experimentation by partially substituting cement by 10% and 20% using POFA. 5% and 10% use green mussel shell waste which will later be compared with the CTB Job mix formula which complies with the general specifications by testing the compressive strength of concrete and analysis of CTB work unit prices per 1 m3. The results of this study revealed that the highest compressive strength of 5.5 MPa occurred in 20% POFA substituted CTB and 10% green mussel shells. This compressive strength is higher than Normal CTB. However, from the results of price analysis it can be seen that 20% POFA substitution CTB and 10% green mussel shells require a 3.7% higher cost than the Normal CTB price or a difference of Rp.19,792.22.

Published: October 2023

Background The position of the eyebrows is critical when planning blepharoptosis surgery. However, insufficient scholarly attention has been paid to the details of postoperative eyebrow height changes at each anatomical landmark. This study investigated the effect of blepharoptosis surgery on brow height and evaluated the change in brow position.Methods After a retrospective review of 247 patients, this study analyzed 53 patients (106 eyelids) who underwent levator and Müller’s complex advancement between March 2010 and January 2022. Brow heights were measured from the distance between the upper brow margin of each landmark and horizontal line of pupillary center on a digital photograph.Results The mean change of eyebrow lowering was 1.54 mm (P<0.001) at the medial canthus, 1.29 mm (P<0.001) at the medial limbus, 1.44 mm (P<0.001) at the center of the pupil, 1.40 mm (P<0.001) at the lateral limbus, 1.15 mm (P=0.001) at the lateral canthus, and 0.75 mm (P=0.021) at the lateral eyebrow end. The brow change was most prominent at medial canthus and least prominent at the lateral brow end. The preoperative brow position was only statistically significant factor predicting brow height descent after surgery according to multiple linear regression analysis (R2=0.305, B=–0.375, P<0.001).Conclusions The eyebrows lowered in most patients after blepharoptosis surgery. The preoperative brow position is the most important factor in predicting the change in brow height after blepharoptosis surgery.
Modified cervicofacial transposition flap: a case report of aesthetic considerations after resection of a huge facial squamous cell carcinoma
Authors: Kim Young Jun , Cheon Ji Seon , Choi Min Hyub , Choi Woo Young
Published: October 2023

The cheek, a highly visible and significant aspect of an individual’s appearance, is situated adjacent to several structures involved in facial expressions, including the eye, mouth, and surrounding facial muscles. Consequently, aesthetic reconstruction for large cutaneous defects of the cheek remains a challenge for plastic surgeons. We experienced a case of an 83-year-old woman with a large (7×10 cm) facial defect following the removal of squamous cell carcinoma. We elevated a cervicofacial skin flap containing the superficial layer of the superficial musculoaponeurotic system and a blood supply via the dermal plexus in a random pattern. Through this method, we achieved aesthetically favorable reconstruction of a large facial defect using a cervicofacial transposition skin flap. By avoiding extensive dissection, we achieved adequate coverage for even a quite sizable facial defect, with a short recovery time. This method prevented facial nerve injury and made it possible to simultaneously obtain an aesthetically favorable outcome.

Relativistic effects on the chemistry of heavier elements: why not given proper importance in chemistry education at the undergraduate and postgraduate level?
Authors: Das Ankita , Das Udita , Das Ruhi , Das Asim K.
Published: October 2023

Relativistic effects are important to understand the chemistry of heavier elements across the periodic table (PT). Three important relativistic effects are: contraction of s- and p-orbitals (direct relativistic effect), expansion of d- and f-orbitals (indirect relativistic effect) and spin–orbit (SO) coupling to split the p-, d- and f-orbitals. Each of these effects is approximately proportional to Z
2 (Z = atomic number) for the valence shell electrons in many electron atoms and consequently, these relativistic effects dominantly control the properties of the heavier elements (mainly the 6th and 7th period elements). These aspects are not given the proper importance in most of the inorganic chemistry text books and in chemistry education at the university level.
Assessing the Importance of Sample Choice and Selectivity for Sex Segregation in College Majors: A Replication of Ochsenfeld (2016)
Authors: Patzina Alexander , Toussaint Carina
Published: October 2023

Ochsenfeld (2016) has found that a substantial part of sex segregation in higher education results from differences in vocational interests (i.e., preferences), while constraints (e.g., relative math grades) play only a minor role. We challenge the validity of these findings because earlier work employed a cross-sectional student sample and might therefore suffer from endogenous selection (i.e., post hoc rationalizations due to simultaneous reporting of majors and preferences) and postoutcome collider bias (i.e., conditioning on the outcome). Our replication study uses panel data (National Educational Panel Study, NEPS-SC4) that allow adjustment for the two sources of bias through the application of a pretransition preference measure and inverse probability weighting. Our analyses demonstrate the validity of prior research. Furthermore, our analysis indicates that the explanatory power of the overall model and the role of constraints for sex segregation in majors vary across the propensity of sample inclusion, thereby demonstrating the importance of sample composition for testing sociological theories.
Modulation of Trust in Borderline Personality Disorder by Script-Based Imaginal Exposure to Betrayal

Published: October 2023

Interpersonal and trust-related difficulties are central features of borderline personality disorder (BPD). In this study, we applied script-driven betrayal imagery to evoke mistrustful behavior in a social reinforcement learning task. In 21 BPD and 20 healthy control (HC) participants, we compared this approach to the standard confederate paradigm used in research studies. The script-driven imagery evoked a transient increase in negative affect and also decreased trusting behavior to a similar degree in both groups. Across conditions, we also replicated previously reported between-group differences in negative affect (increased in BPD) and task behavior (more sensitive to social cues in BPD). These results support the validity of script-driven imagery as an alternative social task stimulus. This script-driven imagery approach is appealing for clinical research studies on reinforcement learning because it eliminates deception, scales easily, and evokes disorder-specific states of social difficulty.
Accuracy and Bias in Facial Trustworthiness Appraisals in Borderline Personality Disorder
Authors: Miano Annemarie , Lustig Sophia , Meyerding Luca , Barnow Sven
Published: October 2023

Individuals with borderline personality disorder (BPD) have shown a negativity bias, whereas the general population has shown a positivity bias in their trustworthiness appraisal of others. We tested if individuals with BPD are more negative but also more realistic with their appraisals. Trustworthiness was objectified on an external criterion. The influence of childhood trauma was investigated. Facial photographs of peace prize laureates and sentenced murderers were presented. Participants with BPD and healthy controls (HC) rated the trustworthiness of the targets. Bias and sensitivity were measured using signal detection theory. The BPD group was more negatively biased compared to HC, but not more sensitive in discriminating between the two groups. When correcting for experienced childhood abuse and neglect, the authors found that group differences in bias disappeared. Individuals with BPD might not be more sensitive in discriminating between, on average, more or less trustworthy targets, but they have developed a negativity bias to ensure the detection of untrustworthiness.

Published: October 2023

The brain is an organ that functions as a network of many elements connected in a nonuniform manner. In the brain, the neocortex is evolutionarily newest and is thought to be primarily responsible for the high intelligence of mammals. In the mature mammalian brain, all cortical regions are expected to have some degree of homology, but have some variations of local circuits to achieve specific functions performed by individual regions. However, few cellular-level studies have examined how the networks within different cortical regions differ. This study aimed to find rules for systematic changes of connectivity (microconnectomes) across 16 different cortical region groups. We also observed unknown trends in basic parametersin vitrosuch as firing rate and layer thickness across brain regions. Results revealed that the frontal group shows unique characteristics such as dense active neurons, thick cortex, and strong connections with deeper layers. This suggests the frontal side of the cortex is inherently capable of driving, even in isolation and that frontal nodes provide the driving force generating a global pattern of spontaneous synchronous activity, such as the default mode network. This finding provides a new hypothesis explaining why disruption in the frontal region causes a large impact on mental health.

Published: October 2023

Human startle disease is associated with mutations in distinct genes encoding glycine receptors, transporters or interacting proteins at glycinergic synapses in spinal cord and brainstem. However, a significant number of diagnosed patients does not carry a mutation in the common genesGLRA1,GLRB, andSLC6A5. Recently, studies on solute carrier 7 subfamily 10 (SLC7A10; Asc-1, alanine-serine-cysteine transporter) knock-out (KO) mice displaying a startle disease-like phenotype hypothesized that this transporter might represent a novel candidate for human startle disease. Here, we screened 51 patients from our patient cohort negative for the common genes and found three exonic (one missense, two synonymous), seven intronic, and single nucleotide changes in the 5′ and 3′ untranslated regions (UTRs) in Asc-1. The identified missense mutation Asc-1G307Rfrom a patient with startle disease and developmental delay was investigated in functional studies. At the molecular level, the mutation Asc-1G307Rdid not interfere with cell-surface expression, but disrupted glycine uptake. Substitution of glycine at position 307 to other amino acids, e.g., to alanine or tryptophan did not affect trafficking or glycine transport. By contrast, G307K disrupted glycine transport similar to the G307R mutation found in the patient. Structurally, the disrupted function in variants carrying positively charged residues can be explained by local structural rearrangements because of the large positively charged side chain. Thus, our data suggest thatSLC7A10may represent a rare but novel gene associated with human startle disease and developmental delay.

In this paper, we study the equiform Bishop formulae for the equiform timelike curves in 3-dimensional Minkowski space where the equiform timelike spherical curves are defined according to the equiform Bishop frame. We establish a necessary and sufficient condition for an equiform timelike curve to be an equiform timelike spherical curve. Furthermore, we give certain characterizations of equiform spherical curves in 3-dimensional Minkowski space, which are timelike with an equiform spacelike principal normal vector.

Kings and queens on mission: the image of God in God’s plan for disability
Authors: Deuel David , Grills Nathan
Published: October 2023

All people God has called and gifted should participate in mission. After all, he crowned us at creation and commissioned us to care for his creation. The Fall sabotaged the creation mission both relationally and practically. But God’s image abides unchanged. In Christ, God renews us in his mission to redeem people. Also, we are a kingdom of families being renewed. Family support empowers impairment in mission. Our understanding of God’s Image corrects misunderstandings about people with disability in mission. It also increases our capacity to appreciate God’s hand in mission blessing.
JAK2 exon 12 variants in vietnamese patients with JAK2 V617F-negative primary myelofibrosis
Authors: Thy Ngoc Nguyen , Manh Quyet Ha
Published: October 2023

Primary myelofibrosis is the severe form of myeloproliferative neoplasms that causes scar tissue in the bone marrow, leading to low production of blood cells and thus, life span shortening. Besides the most common variant JAK2 V617F, the association between these disorders with other variants in the JAK2 gene, especially the exon 12 variants have been poorly studied. In our research, the JAK2 exon 12 variants were detected by amplification and sequencing from genomic samples of five cases with V617F-negative primary myelofibrosis. Results showed that among 5/14 primary myelofibrosis patients with V617F-negative profile, only two patients carried exon 12 variants (JAK2 c.1592A>G p.H531R, and c.1613A>C p.H538P). In silico analysis indicated that the variant c.1613A>C p.H538P was novel and potentially pathogenic. The positioning demonstration by Missense3D tools indicated that this variant localized in the proximity to the pathogenic variant V617F, suggesting a potential effect on the enzymatic activity of Janus kinase 2. This initial data can be used as a genetic diagnostic criterion for myeloproliferative neoplasms. Nonetheless, the effect of p.H538P needs to be verified by further investigations.
Digital Literacy Level and Career Satisfaction of Academics

Published: October 2023

Technology affects educational institutions like every other field. Higher education institutions, which are the main source of new knowledge creation and dissemination, are now dominated by digital technologies. The acquisition of digital literacy skills, which is among the 21st-century competencies, is possible with the positive attitudes and skills of academics, who are instructors in higher education institutions, towards the use of digital technologies. As role models in strengthening digital literacy, academics should develop themselves in line with strategies that include elements of the digital age and more active learning, and be able to transfer these strategies to educational practices. Otherwise, it will not be possible to increase the quality of education and it is inevitable for academicians to experience career dissatisfaction with the feeling of failure. Despite the importance of the subject, digital literacy of academicians has not been adequately addressed in the literature and the relationship between academics' digital literacy levels and career satisfaction has not been focused. Based on this gap, in this study, the concept of "digital literacy" is handled specifically for academics working in universities operating in Istanbul, Turkey, and it is aimed to contribute to the literature by revealing the relationship between academics' digital literacy and career satisfaction. The cross-sectional survey method, a quantitative research technique, was utilized in the research as a data collection and analysis tool. For this purpose, the data collected through questionnaires from 304 academics with a simple random sampling method were analyzed. As a result of the analysis, it was found that academics' digital literacy explained the career satisfaction variable by 28.1% at a 0.01 significance level. Finally, the significant positive relationship between academics' digital literacy and career satisfaction can be interpreted as that academics who cannot develop digital literacy skills and transfer these skills to teaching environments will not be able to achieve career satisfaction by experiencing a sense of failure because they cannot provide an education in line with the expectations of the digital age. In addition, according to the research findings, it was found that the digital literacy and career satisfaction levels of the academicians differ according to age, working time, academic title, and having a personal web page.

ABSTRACT Permanent canines are essential for the preservation of the stomatognathic system, as they are part of the occlusal and aesthetic function and balance. During the normal development of occlusion, canines follow a long and complex trajectory until their eruption, that is, they are more likely to suffer disturbances during this process. Removal of the permanent canine should only be considered in extreme cases, where the canine itself is not susceptible to orthodontic traction. Orthodontic traction is the most indicated treatment due to the high morphofunctional and aesthetic value of the permanent canine. The aim of this study is to report a clinical case of traction surgery of the superior permanent canine included in the maxilla. A 13-year-old female patient attended the dental clinic at the Nilton Lins University accompanied by her guardian, referred by an orthodontistfor canine traction surgery. during the examIn the clinical analysis, tooth 13 was absent from the dental arch. The patient had a computed tomography scan, where it was possible to verify the actual position of the toothimpacted with the partially erupted crown on the alveolar ridge. After planning, surgery was performed to install an orthodontic button and adapt the ligature with a 0.30 mm wire. After the 10-month follow-up period, the presence of the tooth in arch, completely erupted, was observed, showing effectiveness in the proposed treatment. Therefore, the procedure for bonding the orthodontic device was performed satisfactorily without complications or intercurrences, making it possible to continue the orthodontic treatment. The patient remains under follow-up.

Published: October 2023

ABSTRACT Objective: The present study analyzed the biomechanical behavior of the generated stress on the external surface of the rehabilitation elements (implants, components and infrastructures) according to different occlusion patterns on a fixed partial denture on osseointegrated implants. Method: The experimental groups varied according to the location of the occlusal load applied to the Fixed partial denture, with a total occlusal load of 750N in all groups, opting for greater loads on the occlusal table of the molar in relation to the premolar. This evaluation was performed by the finite element method with simulations by the AnsysWorkbench 16.0 Software program. Results: The results analyzed for implants and their components showed that the more posterior the occlusal loading, the greater the stress developed (group 4), always in the connection area between the prosthetic component and the implant, as this location can induce greater screw loosening. The results analyzed for the infrastructures showed that the most distributed occlusal loading possible (group 1) is the best situation for generating less stress. However, even in group 3 which obtained the highest stresses in the critical area of the prosthetic connection, the zirconia flexural strength values generated were not worrisome. Conclusion: It can be concluded that the occlusal adjustment of Fixed partial dentures are preponderant and decisive factors for correct biomechanics and preservation of the system in the long term in order to avoid possible damage and/or failures, and exert significant and notorious differences in the behavior of all structures studied herein.

ABSTRACT The Apodi-Mossoró River Basin is important for the west region of the state of Rio Grande do Norte (RN), Brazil. The rapid increase in population and consequent need for space has resulted in anthropogenic actions, such as the segmentation of the river course within the municipality of Mossoró, RN. The objective of this study was to assess the effects of this segmentation on soils in alluvial environments. Soil collection points were defined in natural and anthropized areas in the Mossoró urban segment; soil profiles were described and collected; and samples of the soil 0-10 and 10-20 cm were collected. The samples were subjected to physical and chemical analyses to determine granulometry, density, aggregates, pH in water, available phosphorus (P), exchangeable bases, potential acidity, total organic carbon, nitrogen, and micronutrients (Cu and Zn). Maps of location and land use and cover were developed. The soil found in the natural area was classified as Neossolo Fluvico Psamitico eutrico, presenting typical physical and chemical characteristics of this soil class, with variable texture and P contents along the soil profile. The soil in the anthropized area was classified as Planossolo Haplico Carbonatico vertissolico, with Ap Horizon presenting a sandy loam texture, since it is a horizon formed due to anthropogenic activity in the environment. All horizons and profiles presented high pH. The evaluated areas formed different groups regarding soil physical and chemical attributes, with overlapping points that can be explained by anthropogenic actions, even in the environment considered natural.

ABSTRACT Technologies that improve water use efficiency (WUE) and increase crop yields are essential for the development of a responsible and productive agriculture. Therefore, the objective of this study was to evaluate economical planting beds with the use of mulching and application of different irrigation water depths as a water-saving technology, and determine the irrigation water depth that promote the optimal plant development and fruit yield and quality of two cherry tomato cultivars. The experiment was conducted at the Federal Rural University of Pernambuco, Serra Talhada, PE, Brazil. A randomized block experimental design with split-plots (5×2) was used, with plots consisting of five irrigation water depths (25%, 50%, 75%, 100%, and 125% of the crop evapotranspiration - ETc) and subplots consisting of two cherry tomato cultivars (Carolina and Yubi), with four replications, totaling 40 experimental units. The development of tomato plants was evaluated through biometric measurements of stem diameter, plant height, and canopy area. Additionally, the following variables were evaluated during fruit harvest: number of fruits, mean fruit weight, fruit diameter, fruit yield, WUE, titratable acidity, pH, and soluble solids content. The economical planting beds promoted increases in WUE. Irrigation water depths lower than 100% of ETc resulted in better plant development and higher fruit yield, number of fruits, and WUE for the evaluated cherry tomato plants. The cultivar Carolina exhibited higher production performance compared to Yubi.

ABSTRACT Physalis angulata L. (Solanaceae), known as ‘camapu’, has pharmacological and agroindustrial potentials, but information on the ecophysiological aspects that influence germination is scarce. In this context, the objective was to evaluate the expression of the physiological potential of P. angulata seeds as a function of the maturation stage, temperature, substrate and light condition. Four experiments were conducted: in the first, the maturation stages (green calyx + fruit, yellow calyx + fruit and light brown calyx + fruit) were evaluated at temperatures of 25, 30 and 35 °C, separately; in the second, the interaction between the temperatures of 35, 40 and 45 °C and types of substrate (on paper, between paper and between vermiculite) was tested in a 3x3 factorial scheme (temperatures as the first factor and types of substrates as the second factor); in the third experiment, the effect of light (absence of light, white light, red and far-red light) was evaluated; and, in the fourth, increasing values of photoperiods (0, 8, 12 and 16 hours) were used. In all experiments, the design was completely randomized with four replicates of 50 seeds. Analysis of the results showed that there was no interaction between the temperatures and the substrates tested, demonstrating the isolated action of the factors. P. angulata seeds expressed better physiological potential when the calyx and fruit are yellow. In the germination test, the seeds should be sown between paper towels, under temperature of 35 °C and absence of light.

ABSTRACT This study aimed to understand mothers’ experiences of school closures due to social distancing measures imposed to combat the COVID-19 pandemic and its impacts on family ties and the perception of motherhood. Twenty middle-class women aged between 29 and 45 who accompanied their children to school activities at home during this period took part in the study. Individual semi-structured interviews were carried out remotely. The results showed that the pandemic has resulted in significant changes in family ties. The transition to remote classes has led to an accumulation of activities undertaken by mothers in the domestic context, resulting in overload and requiring extra dedication to their children’s education. In addition, the participants were reflective about the bond with their children and the values related to education. The overload experienced by the women was highlighted, with potential repercussions on the mental health and well-being of their families.

Resumo Introdução Estudos sugerem que a espessura diafrag-mática (ED) está associada à força muscular inspiratória e, consequentemente, à melhor eficiência ventilatória e mecânica. Por outro lado, doenças infecciosas como a COVID-19 podem impactar a estrutura e função do apa-relho respiratório. Objetivo Avaliar a associação entre a ED e o desempenho físico (DF) de atletas e os efeitos da infecção por COVID-19 sobre esses parâmetros. Métodos Trata-se de um estudo transversal envolvendo 63 atletas de diferentes modalidades esportivas, de ambos os sexos (feminino: 16,67 ± 5,03 anos, 52,09 ± 14,01 kg, 155,90 ± 13,86 cm; masculino 23,44 ± 9,65 anos, 72,24 ± 14,18 kg, 174,84 ± 6,84 cm), que foram submetidos à avaliação da ED por meio de ultrassom e, em seguida, ao teste de DF (Yo-Yo test) para determinar o consumo máximo de oxigênio (VO2max). Utilizou-se a correlação de Pearson para verificar a associação entre VO2max e ED, e o teste t de Student para diferenças entre atletas com diagnóstico positivo e negativo para COVID-19. O nível de significância foi ajustado em 5%. Resultados Não houve associação entre ED e DF (r = 0,30 e p = 0,22) e não houve diferença entre os atletas não infectados e infectados por COVID-19 em relação à ED (57,00 ± 0,26 vs 52,00 ± 0,25%; p = 0,91) e DF (43,88 ± 2,29 vs 38,34 ± 13,61 ml/kg/min; p = 0,69). Conclusão A ED não foi associada ao consumo máximo de oxigênio em atletas. Além disso, atletas infectados por COVID-19 não exibiram diferenças no VO2max e ED em relação aos não infectados.

Abstract: Aim This study aimed to evaluate whether the upper São Francisco River basin floodplain is still used as a nursery by migratory fish and present the current status of the area’s ichthyofauna after almost 40 years since the only survey was conducted in the region. Methods Sampling occurred in seven perennial lagoons and six temporaries from São Francisco River or its direct tributaries using gillnets and trawls. Temperature, pH, and transparency of each lagoon were measured. The estimated richness was calculated, and the fish assemblage from both perennial and temporary lagoons was compared using NMDS and ANOSIM. Results Forty species were captured, of which four were non-native and three were migratory. Although there was a low abundance of migratory species, most captured individuals were juveniles. Moreover, the perennial lagoons showed higher species richness. Conclusions After almost 40 years, the floodplain lagoons of the upper São Francisco basin remain important for the recruitment of migratory species and harbor an impressive proportion of fish fauna in the upper São Francisco area. However, the reduction of migratory species and the presence of non-natives may be a sign of the degradation of these environments, emphasizing the need for conservation measures in this area.
