Abstract
Sleep holds significant importance for maintaining health and aiding in illness recovery. Its deprivation impacts all human organ systems, from cognitive function, social interaction, and work capacity to cellular regeneration and immune function. Therefore, sleep plays a crucial role in our body and maintaining health and well-being. Given its importance and close relationship with the neurodevelopment and growth of children and adolescents, this topic is highly significant in pediatric and adolescent health consultations. Family physicians, due to their proximity and understanding of the individual within their family, have the prerogative to contribute to family literacy, empower them, and significantly enhance the quality of life and overall health.

Abstract
INTRODUCTION Neurocysticercosis (NCC), a possible cause of epilepsy with limited epidemiological data in the Dominican Republic, is endemic in four provinces in the country's south-western region. This study aimed to determine the association between NCC and epilepsy among people living in these endemic regions, and to obtain preliminary data on the prevalence of NCC in these provinces. PATIENTS AND METHODS A case-control design was used, consisting of 111 patients with epilepsy with unknown causes, and 60 controls without epilepsy or NCC. The diagnosis of NCC was based on computed tomography and magnetic resonance imaging of the skull, as well as Western immunoblotting for serum antibodies using Taenia solium, following the criteria of Del Brutto et al. RESULTS. NCC was found in 27% of the epileptic patients (n = 30/111) and in 5% of the controls (n = 3/60); the probability of the epileptic patients having NCC was seven times higher than the controls (odds ratio = 7.04, 95% confidence interval: 2.04-24.18; p < 0.001). The participants' sociodemographic characteristics, including their age, sex, level of education, occupation, and province of residence presented no statistical significance in terms of their association with NCC. CONCLUSIONS This study suggests that NCC is strongly associated with epilepsy in the south-western region of the Dominican Republic, and highlights the need for public health measures to improve the prevention, diagnosis and treatment of both diseases.

Abstract
The Brazilian Midwest is responsible for 54.3% of the country's soybean production. Adequate storage technologies are essential to maintain physical, physiological, and sanitary seed qualities while also minimizing deterioration processes and consequent germination and vigor declines. In this context, the aim of the present study was to evaluate the physiological potential and physical qualities of soybean seeds stored under different environmental conditions and storage bag depths. Assays were carried out in September 2021 employing Foco 74i77 RSF IPRO cultivar seeds stored from April to August 2021 under three conditions, as follows: chilled at an average temperature of ≤20 °C, at an average temperature of ≤25 °C using a with blanket, and in without blanket warehouse structure at an average temperature of ≥25 °C with no with blanket. A completely randomized 3x3 factorial experimental design was applied, comprising three storage environments and three bag positions (top, middle, and bottom), with three replication each. Physical, physiological, and biochemical tests were performed on the stored seeds. The findings indicate better seed preservation in the chilled environment or when using a with blanket, with significant differences noted for seeds stored the middle of the storage bag. Therefore, soybean seed storage in a chilled environment or using a with blanket aids in slowing down the seed deterioration processes, preserving physiological quality and vigor compared to a conventional storage environment. Additionally, the quality of soybean seeds stored under these conditions in the middle of storage bags is maintained.

[PMID: 37639824 DOI: 10.1016/j.aquatox.2023.106664] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 08/12/2023] [Accepted: 08/15/2023] [Indexed: 08/31/2023]
Abstract
Wildfires have emerged as a global ecological concern due to their wide-ranging off-site effects. One particular consequence is the adverse impact on aquatic environments, as wildfires are acknowledged as a significant source of aquatic contamination through ash runoffs containing toxic compounds. Yet, amphibian response to this source of contamination remains largely undocumented. This study assessed how ash runoffs from Eucalyptus sp. and Pinus sp. affect early aquatic life-stages of Xenopus laevis. Embryos and tadpoles were exposed, respectively, for 96 h and 14 days to serial concentrations (26.9% - 100%) of aqueous extracts of ashes (AEAs; 10 gL-1) composed of eucalypt (ELS) and pine (PLS) ashes. Mortality and development were monitored, and biometric data (snout-to-vent, tail and total length, and weight) measured. Sub-individual endpoints regarding oxidative stress (catalase-CAT; total glutathione-TG; lipid peroxidation-TBARS), neurotoxicity (acetylcholinesterase-AChE), transformation metabolism (glutathione-S-transferase-GST) and energetic metabolism (carbohydrate, lipid and protein content and O2 consumption), were also measured. The two AEAs induced no significant lethal effects on embryos or tadpoles. However, in general, AEAs caused a developmental delay in both life stages. Effects of AEAs on biometric endpoint were only reported for tadpoles, which showed a decreased body length (snout-to-vent, tail and total) and weight (embryos were not weighed), with PLS exerting higher effect than ELS. As for the sub-individual endpoints, embryos showed mostly no alterations on the activity of the monitored parameters, except for PLS, which reduced embryos' carbohydrate content (at ≥59.2%) and increased O2 consumption (at ≥35.0%). Regarding tadpoles, AEA exposure decreased the activity of CAT and GST (at ≥26.0%) and decreased carbohydrate (at ≥26.0%) and lipid (at ≥45.5%), whereas oxygen consumption increased (at ≥26.0%) only on PLS. Overall, the tested AEAs differentially affected amphibians across life-stages, indicating that plant coverage might affect ash toxicity.

Abstract
INTRODUCTION Consistent with the Bayesian brain hypothesis, the within-subject variability of pain intensity reports as captured with the Focused Analgesia Selection Test (FAST) might be a surrogate measure of the certainty in ascending noxious signals. The outcomes of a non-pain-related task, the rubber hand illusion, were hypothesized to reflect the same construct. This study aimed to explore whether within-subject differences in variability of pain intensity reports and the outcomes of the rubber hand illusion might be related. METHODS Nonclinical participants underwent the classic rubber hand illusion under synchronous (experimental) and asynchronous (control) conditions. Two outcomes were assessed: proprioceptive drift and feeling of ownership. Thereafter, participants underwent the FAST to assess the within-subject variability of pain reports in response to heat stimuli. Intraclass correlation (ICC) and the correlation coefficient (R2) were the main outcomes. Spearman's correlations were used to assess associations between the outcomes of the 2 tasks. RESULTS Thirty-six volunteers completed the study. Both FAST outcomes-ICC (Spearman's r = 0.355, p = 0.033) and R2 (Spearman's r = 0.349, p = 0.037)-were positively correlated with proprioceptive drift in the synchronous but not asynchronous conditions (p > 0.05). The subjective feeling of ownership and FAST outcomes did not correlate (p > 0.05). CONCLUSIONS The associations between the 2 tasks' outcomes imply that both tasks at least partly assess similar constructs. Current knowledge suggests that this construct represents the person's certainty in perceiving ascending sensory signals, or, in Bayesian terminology, the certainty of the likelihood.

Abstract
Footwear with or without custom foot orthotics have the potential to improve comfort, but the link with running performance needs further investigation. We systematically reviewed the association of footwear comfort on running economy in recreational runners. Nine electronic databases were searched from inception to March 2020. Eligible studies investigated both direct outcome measures of running performance (e.g. running speed) and/or physiological measures (e.g. running economy (RE)) alongside comfort for each footwear condition tested. Methodological quality was assessed using the "Effective Public Health Practice Project" (EPHPP). RE during submaximal running was the most common physiological outcome reported in 4 of the 6 eligible studies. The absolute difference in RE between the most and least comfortable footwear condition was computed, and meta-analysis was conducted using a random effect model. The most comfortable footwear is associated with a reduction in oxygen consumption (MD: -2.06 mL.kg-1.min-1, 95%CI: -3.71, -0.42, P = 0.01) while running at a set submaximal speed. There was no significant heterogeneity (I2 = 0%, P = 0.82). EPHPP quality assessment demonstrated weak quality of the studies, due to reporting bias and failing to disclose the psychometric properties of the outcome measures. It can be concluded with moderate certainty that improved RE in recreational athletes is associated with wearing more comfortable footwear compared to less comfortable footwear.HighlightsThis systematic review reports on the association of footwear comfort with running economy in recreational runners.Running economy during constant submaximal running is likely improved in recreational runners wearing more comfortable compared to less comfortable footwear.This finding is based on a meta-analysis, including four studies, showing a small but statistically significant decreased oxygen consumption at steady state speeds while wearing the most comfortable footwear.

Abstract
Abstract
Background
Aortic stenosis (AS) is one of the main valvular heart diseases in developed countries. Degenerative fibrocalcific aortic stenosis is a progressive disease of the valve and ultimately of the myocardium, which can be fatal when symptomatic. There is no medical treatment that can halt or delay its progression. AS does not evolve linearly over time, and not every patient has the same progression rate.
Aims
The aim of this study is to 1) compare different mathematical models of aortic stenosis progression, 2) cluster patients into rapid and slow progressors and explore possible predictors, 4) evaluate the impact of different progression rates on cardiac structure and function, and 5) evaluate survival and optimal timing for follow-up and treatment.
Methods
We retrospectively studied consecutive patients with aortic peak velocities from 2012 to 2020. Follow-up echocardiograms, seriated biomarker assessment, and clinical records were consulted, providing a multiparametric data frame for longitudinal and dynamic modeling of aortic stenosis progression and its consequences.
Results
This study included 9583 studies from 752 patients with a median total follow-up of 4.26 years (interquartile range: 1.28 to 7.24 years). A logistic model was selected with the best accuracy to predict the rate of AS progression. Patients were categorized into slow and rapid progressors in a ratio of 5:1. Multiparametric analysis showed no association between these profiles and clinical variables. However, anti-hypertensive drugs before and after adjustment for blood pressure control (Calcium Channel Blockers, p=0.013, OR 0.50) were associated with slower progression. Meanwhile, elevated inflammatory markers (erythrocyte sedimentation rate, p=0.01) were associated with faster AS progression. Despite no survival difference between these groups, higher rates of valvular intervention were registered in rapid progressors (p<0.001). Moreover, faster progressors were associated with earlier cardiac damage (as demonstrated by early onset of moderate mitral and tricuspid valve regurgitation, left auricle dilation, and left ventricle hypertrophy, p<0.05).
Conclusions
These results can potentially modify follow-up times and deliver more personalized and individualized health care to different AS patients, thereby optimizing resources.

Abstract
OBJECTIVE The aim of the study was to investigate sleep characteristics, use of supplements, and training volume of recreational triathletes, and to verify possible associations with perceived performance drops and occurrence of injuries. MATERIALS AND METHODS Recreational triathletes (n=942) answered a questionnaire inquiring about their demographic characteristics, performance, injuries and training volume. RESULTS When comparing athletes who slept more (9-10 hours) with those who slept less, less sleep was associated with a higher prevalence of perceived performance drops. Regarding difficulties in initiating sleep, the absence of initiating difficulties (p<0.001) was a protective factor against perceived performance drops. Regarding weekly training volume, compared to those who trained more than 20 hours, training less than 3 hours (p<0.001), 3-5 hours (p<0.001), or 12-14 hours (p<0.001) were protective factors against perceived performance drops. Concerning training volume and injuries, we found that compared to those who trained more than 20 hours, training 18-20 hours (p<0.001), 15-17 hours (p<0.001), 12-14 hours (p<0.001), 6-8 hours (p<0.001), or 3-5 hours (p<0.001) were protective factors against injuries. CONCLUSIONS Triathletes with a lower sleep quantity and those who have difficulties initiating sleep frequently experience drops in performance. Training volumes can influence both performance and the likelihood of injuries.

Abstract
BackgroundJuvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children and adolescents [1]. The manifestation of JIA may include joint swelling, tenderness, and painful limitation with joint movement. Only few studies have explored the effect of foot orthoses (FOs) alone in children with JIA [2,3]. These studies showed FOs can reduce pain in children with JIA, however, further research with larger sample sizes and longer follow-ups are needed [4]. Prescribing FOs on the same day of the initial assessment may promote early clinical and targeted intervention, which is the gold standard approach in paediatric rheumatology.ObjectivesThis single blinded multicentre randomised clinical trial (RCT) aims to investigate the effect of customised prefabricated FOs in reducing pain amongst children and adolescents with JIA.MethodsOverall, 66 children and adolescents with JIA presenting with foot symptoms were recruited from the Sydney Children’s Hospitals Network (Westmead and Randwick) and John Hunter Children’s Hospital (Newcastle). The primary outcome measure was pain with a minimal clinical significance of 8mm on the visual analogue scale (VAS). Participants were randomly allocated to receive either customised prefabricated or sham FOs. The trial intervention was a low-density Slimflex Simple device that was customised at chair-side. The control (sham) device was made of 2mm flat leather board with no corrective modifications. Standardised tests such as the Foot Posture Index, navicular drift and drop were used to identify biomechanical abnormalities. The FOs were worn for a total of 12 months, with data collected at baseline, 4 weeks, 3, 6 months and 12 months.ResultsReduction in self-reported pain was statistically and clinically significant at 4-weeks (p=0.018, -14.92 [-27.30, -2.55]) and 3 months (p=<0.001, -28.93 [-40.90, -16.96]) post intervention in favour of the trial group. The 6- and 12-month follow-ups were not statistically or clinically significant. Parent reported pain was statistically and clinically significant at the 3-month (p=<0.001, -21.92 [-33.16, -10.67]) in the reduction of pain in favour of the trial group. However, parent reported pain was not statistically significant at the 4-week, 6- and 12- month follow-ups. These results are similar to child reported pain with a p-value of less than 0.001 and average coefficients twice that of the clinical significance cut-off for VAS pain in paediatric rheumatology. The trial intervention was safe and tolerated well by participants with high compliance and adherence rates.ConclusionResults of this clinical trial indicate customised preformed FOs can be effective in reducing pain and in children with JIA experiencing foot and ankle symptoms. Significant clinical effects appear to be within the first 3-months of intervention prescription and reduce beyond 6 months. Overall, this podiatric intervention was safe, inexpensive, well tolerated and it can be easily implemented as part of the multidisciplinary paediatric rheumatology care.References[1]Ravelli A, Martini A.

Abstract
Copper (Cu) is an essential element for organism's metabolism, being controversially listed as a priority pollutant. Importantly, the toxicity of Cu has been linked to several cell death pathways. Thus, this study aimed to assess if macroautophagic pathways are triggered by Cu in zebrafish gill, the main target of waterborne pollutants. The electron microscopy findings indicated that Cu induced profound impacts on zebrafish gill structure and functions, being this tissue a biomarker sensitive enough to indicate early toxic effects. The findings also support a clear impairment of autophagy, througth the absence of phagossomes and the significant down-regulation mRNA transcript levels of microtubule-associated protein light chain 3 (LC3). The reduction of LC3 levels was often associated to an increase of apoptotic activation, indicating that the inhibition of macroautophagy triggers apoptosis in zebrafish gills. This study highlighted that the autophagic down-regulation might be affected through the activation of other cell death signaling pathway.

Abstract
BACKGROUND/OBJECTIVES Older patients with asthma or chronic obstructive pulmonary disease (COPD) are particularly susceptible to inhaler technique errors and poor clinical outcomes. Several factors may influence their risk, but most studies are inconsistent and contradictory. We developed a tool for the major predictors of individual risk in these patients. DESIGN, SETTING AND PARTICIPANTS In this multicentre, cross-sectional study, several demographic, socioeconomic and clinical characteristics were collected as potential predictors. Clinical features and inhaler technique performance were the main outcomes. Linear and logistic regression models were set up to identify significant variables. Subgroup analysis was performed according to age, cognitive performance and different types of inhalers. RESULTS We included 130 participants, mean age of 74.4 (± 6.4) years. Mean years of device use were 5.8 (± 7.3). Inhaler errors affected 71.6% (95% CI 64-78.5) and critical mistakes 31.1% (95% CI 24-38.8). There were respiratory comorbidities in 82.3% of participants, and 56.2% had moderate to severe disease. A predictive score of misuse probability was developed for clinical practice, including points attributable to cognitive score, adherence and having received previous education on a placebo device. Other significant variables of individual risk were having respiratory allergies or comorbidities, smoking status, depression and educational level. Worse performance was detected in cognitively impaired patients older than 75 years who were using dry powder inhalers (DPI). Lung function was associated with smoking load, incorrect dose activation and absent end pause after inhalation. CONCLUSIONS Individual risk assessment in older individuals should focus on inhaler technique performance (mainly on dose activation and end pause) and adherence, smoking, respiratory comorbidities and cognitive impairment. Placebo device training provided by doctors seems to best suit these patients.

Abstract
Abstract
Background
The Homeless People is marked by serious social vulnerability, related to the absence of human dignity. Requirements of personal and residential documents, reception and inadequate approaches are barriers to access these people. The creation of Street Medical Consultation (CnaR), based on the logic of harm reduction in association with the other services, is a strategy that seeks to expand access to the services of the Public Healthcare System (SUS) in Brazil. The research aimed to analyze the characteristics and vulnerabilities of this population, the performance of CnaR and its articulation with services from the health care and the social assistance care network.
Methods
Study of a qualitative approach using 8 semi-structured interviews and the Thematic Content Analysis method. The study scenario was the CnaR multiprofissional team in a city in the interior of São Paulo.
Results
Three categories were found: (1) Population in Street Situation - complexity of those who live on the street: prejudices, violence and barriers in society and health institutions constitute a process of invisibility. (2) CnaR's work in the perspective of harm reduction: it is organized to meet the clinical and alcohol and other drugs demands through fixed fields, mobile fields and team meeting. (3) Beyond CnaR - network relationships: bringing dynamics to relationships, being strengthened or weakened. Ignorance of the service and their performance also generates CnaR invisibility process. The strategies developed include coping, dialogue, building partnerships and the process of visibility and fighting for the rights of the Homeless Persons.
Conclusions
CnaR finds itself as an insufficient service to meet all the demands of this vulnerable population in isolation, needing the network to expand access to health and other goods. It is necessary to combat prejudice against this population among health professionals and develop more efficient intersectoral articulation.
Key messages
The Homeless People have serious vulnerability and need humanization, guaranteeing equity in assistance in all sectors of society, especially the health care and the social assistance. The Street Medical Consultation faces performance difficulties to guarantee access to the Homeless People within the intersectoral network, often being the sole responsible for this population.

Abstract
Introduction
Carnival is a popular festival that was introduced in Brazil from the European heritage. However, it was the enslaved African people who saw forms and processes of resistance for the construction of identity during this festive period. The reframing and resistance that blacks establish with carnival is the result of a cultural need to stay alive both as a subject and as a collective. This is how samba schools emerge in the urban peripheries of Rio de Janeiro as a form of artistic, cultural and leisure production. Associations acquire for themselves the role of the State in providing access to rights that many are denied, neglected or scrapped. In these schools, it is possible to observe a relationship of belonging and donation (”principle of gift”) on the part of their so-called community, they are passions and meanings that produce relationships of self-care reaffirmation of intersubjectivity.
Objective
This work aims to identify the carnival as a space for the production of projects, resistances and protagonisms and to analyze the meanings of the subjective processes of health, disease, care and carnival, through the narratives of a samba school community.
Methodology
This is an exploratory analysis of a qualitative approach in public health. A samba school was chosen from the special group of the capixaba carnival, which is located in a peripheral region. We will use it to define snowball technical sampling. The data will be collected through semi-structured interviews and on-site observations by the researcher. The data analysis methodology used will be discourse analysis.
Expected Results
It is expected to understand the different practices and processes of health, disease, care and carnival, among a peripheral community that is part of a samba school.
Key messages
This work aims to analyze health care about a cultural aspect of marginalized populations and how health policies are related to carnival. Impact on the production of knowledge about popular culture and health.

Abstract
Abstract
Objective
To know the dynamic processes that involve the production of care for women in situations of violence.
Methods
Study of qualitative approach and cartographic inspiration based on the theoretical reference of Institutionalism that had as scenario a reference center for women in domestic violence located in Espírito Santo, Brazil. Six professionals who worked directly in the care of women participated in the research. Interventions were carried out, through seven workshops, using storytelling. The material production tools were narratives, the researcher's field diary and the collective field diary, which was built from the record and observation of all the participants in the study. The workshops were held at the center according to the availability of participants and lasted an average of 60 minutes. The meetings were recorded and later transcribed together with the notes of the field diaries, seeking, through a cartography, to give meaning to the experiences lived by the participants. Through the analysis of implication, it was possible to give visibility to the various relationships that constitute a certain reality, in which the researcher is involved.
Results
The study pointed out that violence crosses all women influencing the production of care offered by professionals at the reference center. The narratives multiplied senses contributing to the problematization of the care offered, providing the qualification of other ways of thinking/acting in health.
Conclusions
From an ethical-aesthetic-political paradigm it is possible to produce reflections that broaden the view of care for women in violent situations beyond biological issues, contributing with desirable productive processes in the prevention of violence and the promotion of health.
Key messages
It gives visibility to micropolitical processes and contributes to the construction of policies for women's health capable of welcoming differences and singularities. It shows innovation for the field of qualitative health research, broadening the view on the care of women in situations of violence beyond biological issues.

Abstract
Abstract
Background
A qualitative and exploratory study that analyzed the perspective of access to Integrative and Complementary Practices in Health (PICS) by listening users from a selected service of primary care of a municipality.
Objective
Analyze the access to PICS in a health public service of a municipality in a state of Brazil, from the perspective of users, as well as aimed at understand the needs and desires of health care these users in the search process and use of PICS, identifying facilitators and barriers in this trajectory.
Methods
The theoretical reference from Frenk on access was used, which systematizes the flow of events at the moment when the health need is perceived until the effectiveness of the care, besides the demand and entrance in the health services and the continuity of the treatment. The data collection was done by participant observation and semi-structured interview with 29 users of the service. The narratives were worked through the analysis of thematic content.
Results
The results indicated two groups of PICS: complex medical systems and therapeutic resources. There were differences in the organization of the offer with consequent influence on the different forms of access. It was registered the interest for the use of health care in a non-biomedical logic and a re-signification of the health-disease process in PICS users, contributing to the continuity of health production.
Conclusions
It was concluded that the current models of access analysis do not contemplate the diversities of access to the PICS, and the various possibilities of encounters with these practices allow the identification of the marginality of this care in all cases analyzed.
Key messages
Integrative and Complementary Health Practices gain national relevance as they contribute to the development of health promoting activities, focus on the individual, prevention and comprehensive care. However, considered a controversial topic in a hegemonically biomedical scenario, the incorporation of these new knowledge and practices in the health field occurs in a marginal way.

Abstract
Abstract
Introduction The excessive consumption of sodium is one of the main problems in public health and responsible for the loss of years of a healthy life. The salt added to the meals represents a large part of the salt ingested, and the collaborators/cooks responsible for its addition need careful analysis, and intervention adjusted to the analysed reality, its salt consumption and its perception of saltiness may influence the amount of salt added.
Objectives This study had as main objective to perceive the relationship between the perception of salt of the employees of the Food and Nutrition Unit and the amount of salt added in the meals that were confectioned.
Methodology An observational, analytical, cross-sectional study was conducted, in which 6 selected cooks from the IPSS’s of Águeda participated. In order to estimate the amount of salt added to the meals, 20 samples of meals prepared by the cooks were taken, and a quantitative assessment of average salt per meal was made using Flame Photometry. The cooks were also subjected to two taste sensitivity tests. The data treatment was performed using the statistical software SPSS, and a statistical significance level of 5% was considered.
Results A better perception of the salty taste was observed in the cooks of Institution B. Although there were no differences with statistical significance in the quantity of salt of the meals between the two institutions, the mean and maximum addition of salt in the cooked meals was higher in institution B, regardless of the cook evaluated.
Conclusion The perception of the salty taste of the cooks does not seem to determine the amount of salt added to the meals.

Experimental and DFT studies on the ultrasonic energy-assisted extraction of the phytochemicals of Catharanthus roseus as green corrosion inhibitors for mild steel in NaCl medium.

Abstract
Catharanthus roseus (Apocynaceae family) extract is rich in organic phytochemicals such as alkaloids, polyphenolic compounds, and flavonoids. It contains several functional entities such as fused heterocycles, and hydroxyl and carbonyl groups, which could be useful for corrosion inhibition of mild steel in NaCl environments. In the present work, ultrasonic energy was used to obtain the ethanolic extracts of root and stem which were then tested as corrosion inhibitors for mild steel in the presence of 3.5% NaCl. The corrosion inhibition process was studied by UV-visible spectroscopy, Fourier transform infrared spectroscopy, atomic force microscopy, weight loss, and electrochemical methods. After immersing in the corrosive medium, the microstructures of mild steel were investigated by scanning electron microscopy, X-ray diffraction, and ellipsometry. The extract of C. roseus showed excellent adsorption on mild steel surface as confirmed by DFT calculations. The results indicate that the extract of C. roseus acts as a mixed type corrosion inhibitor, where the stem extract is the most efficient inhibitor in 3.5% NaCl solution possibly due to the higher active area of stem phytochemicals. C. roseus phytochemicals are physisorbed on the 111 Fe surface, and the oxygen non-bonding electron chemisorbed on the polarized state 111 Fe surface.![]()

Abstract
Protein post-translational modifications (PTMs) that potentiate protein aggregation have been implicated in several neurological disorders, including Alzheimer's (AD) and Parkinson's disease (PD). In fact, Tau and alpha-synuclein (ASYN) undergo several PTMs potentiating their aggregation and neurotoxicity. Recent data posits a role for acetylation in Tau and ASYN aggregation. Herein we aimed to clarify the role of Sirtuin-2 (SIRT2) and HDAC6 tubulin deacetylases as well as p300 acetyltransferase in AD and PD neurodegeneration. We used transmitochondrial cybrids that recapitulate pathogenic alterations observed in sporadic PD and AD patient brains and ASYN and Tau cellular models. We confirmed that Tau protein and ASYN are microtubules (MTs)-associated proteins (MAPs). Moreover, our results suggest that α-tubulin acetylation induced by SIRT2 inhibition is functionally associated with the improvement of MT dynamic determined by decreased Tau phosphorylation and by increased Tau/tubulin and ASYN/tubulin binding. Our data provide a strong evidence for a functional role of tubulin and MAPs acetylation on autophagic vesicular traffic and cargo clearance. Additionally, we showed that an accumulation of ASYN oligomers imbalance mitochondrial dynamics, which further compromise autophagy. We also demonstrated that an increase in Tau acetylation is associated with Tau phosphorylation. We found that p300, HDAC6 and SIRT2 influences Tau phosphorylation and autophagic flux in AD. In addition, we demonstrated that p300 and HDAC6 modulate Tau and Tubulin acetylation. Overall, our data disclose the role of Tau and ASYN modifications through acetylation in AD and PD pathology, respectively. Moreover, this study indicates that MTs can be a promising therapeutic target in the field of neurodegenerative disorders in which intracellular transport is altered.
