Pinto, Paulo Henrique Viana,Rodrigues, Caio Henrique Pinke,Rozatto, Juliana Rodrigues,da Silva, Ana Maria Bettoni Rodrigues,Bruni, Aline Thais,da Silva, Marco Antonio Moreira Rodrigues,da Silva, Ricar Korean Academy of Oral and Maxillofacial Radiology 2021 Imaging Science in Dentistry Vol.51 No.3

Purpose: Using images in the facial image comparison process poses a challenge for forensic experts due to limitations such as the presence of facial expressions. The aims of this study were to analyze how morphometric changes in the face during a spontaneous smile influence the facial image comparison process and to evaluate the reproducibility of measurements obtained by digital stereophotogrammetry in these situations. Materials and Methods: Three examiners used digital stereophotogrammetry to obtain 3-dimensional images of the faces of 10 female participants(aged between 23 and 45 years). Photographs of the participants' faces were captured with their faces at rest (group 1) and with a spontaneous smile (group 2), resulting in a total of 60 3-dimensional images. The digital stereophotogrammetry device obtained the images with a 3.5-ms capture time, which prevented undesirable movements of the participants. Linear measurements between facial landmarks were made, in units of millimeters, and the data were subjected to multivariate and univariate statistical analyses using Pirouette^® version 4.5 (InfoMetrix Inc., Woodinville, WA, USA) and Microsoft Excel^® (Microsoft Corp., Redmond, WA, USA), respectively. Results: The measurements that most strongly influenced the separation of the groups were related to the labial/buccal region. In general, the data showed low standard deviations, which differed by less than 10% from the measured mean values, demonstrating that the digital stereophotogrammetry technique was reproducible. Conclusion: The impact of spontaneous smiles on the facial image comparison process should be considered, and digital stereophotogrammetry provided good reproducibility.

Rodrigues Flinta,Gupta Prakash,Khan Afzal Parvez,Chatterjee Tulika,Sandhu Nimrat Kaur,Gupta Latika 대한의학회 2023 Journal of Korean medical science Vol.38 No.12

Plagiarism is one of the most frequent forms of research misconduct in South and East Asian countries. This narrative review examines the factors contributing to research misconduct, emphasizing plagiarism, particularly in South, East and Southeast Asian countries. We conducted a PubMed and Scopus search using the terms plagiarism, Asia, South Asia, East Asia, Southeast Asia, research misconduct and retractions in January of 2022. Articles with missing abstracts, incomplete information about plagiarism, publication dates before 2010, and those unrelated to South, East, and Southeast Asian countries were excluded. The retraction watch database was searched for articles retracted between 9th January 2020 to 9th January 2022. A total of 159 articles were identified, of which 21 were included in the study using the database search criteria mentioned above. The review of articles identified a lack of training in scientific writing and research ethics, publication pressure, permissive attitudes, and inadequate regulatory measures as the primary reasons behind research misconduct in scientific publications. Plagiarism remains a common cause of unethical publications and retractions in regions of Asia (namely South, East and Southeast). Researchers lack training in scientific writing, and substantial gaps exist in understanding various forms of plagiarism, which heavily contribute to the problem. There is an urgent need to foster high research ethics standards and adhere to journal policies. Providing appropriate training in scientific writing among researchers may help improve the knowledge of different types of plagiarism and promote the use of antiplagiarism software, leading to a substantial reduction in the problem.

Rodrigues Flinta,Ziade Nelly,Jatuworapruk Kanon,Caballero-Uribe Carlo V,Khursheed Tayyeba,Gupta Latika 대한의학회 2023 Journal of Korean medical science Vol.38 No.40

Vaccine hesitancy poses a significant global health challenge, fueled by misinformation and anti-vaccination campaigns on social media platforms (SMPs). This study examines the influence of social media on coronavirus disease 2019 (COVID-19) and non-COVID-19 vaccination in Asia during the peri-pandemic period. Through a comprehensive analysis of available literature, we aim to elucidate the role of SMPs in shaping vaccination attitudes and behaviors. The findings highlight the detrimental impact of social media on vaccination efforts and provide insights into addressing vaccine hesitancy during this critical period. A narrative review was conducted by searching the PubMed, Scopus, and Google Scholar databases from inception to May 26, 2022. Only English-language articles involving human participants from Asian countries were included in this review. Out of the 228 articles identified through the database search, 14 articles were included in the final analysis. The prevalence of COVID-19 vaccine hesitancy or negative attitudes towards COVID-19 vaccines in Asian countries was found to be high, ranging from 20% to 55% across countries. Notably, reliance on SMPs for vaccine-related information was associated with a higher likelihood of COVID-19 vaccine hesitancy. This trend coincided with the proliferation of misinformation and conspiracy theories that portrayed COVID-19 vaccines as harmful during the pandemic. Similar patterns were observed for other types of vaccines, including polio, measles mumps and rubella, and diphtheria-tetanus-pertussis vaccines. The use of SMPs was also found to be associated with increased fear among caregivers in Asian countries, as well as a 3–4 times higher likelihood of delayed immunization. SMPs negatively impact vaccine intent in Asia due to misinformation and anti-vaccination campaigns during the pandemic. However, they can be a powerful tool for healthcare providers and policymakers to promote informed decisionmaking. Efforts should focus on leveraging SMPs to disseminate reliable information and combat hesitancy, fostering a well-informed and vaccinated population in Asia.

Boundary Conditions and Fire Behavior of Concrete Filled Tubular Composite Columns

Rodrigues, Joao Paulo C.,Correia, Antonio J.M.,Kodur, Venkatesh Council on Tall Building and Urban Habitat Korea 2018 International journal of high-rise buildings Vol.7 No.4

Concrete-filled steel tubular (CFST) members are commonly used as composite columns in modern construction. However, the current guidelines for members' fire design (EN1994-1-2) have been proved to be unsafe in case the relative slenderness is higher than 0.5. In addition, the simplified design methods of Eurocode 4 are limited to circular and square CFST columns, while in practice columns with rectangular and elliptical hollow sections are being increasingly used because of their architectural aesthetics. In the last years a large experimental research has been carried out at Coimbra University on the topic. They have been tested concrete filled circular, square, rectangular and elliptical hollow columns with restrained thermal elongation. Some parameters such as the slenderness, the type of cross-section geometry as well as the axial and rotational restraint of the surrounding structure to the column have been tested in order to evaluate their influence on the fire resistance of such columns. In this paper it is evaluated the influence of the boundary conditions (pin-ended and semi-rigid end-support conditions) on the behavior of the columns in case of fire. In these tests it could not be seen a marked effect of the tested boundary conditions but it is believed that the increasing of rotational stiffness increases the fire resistance of the columns.

Rodrigues Diogo Moreira,Petersen Rodrigo Lima,Montez Caroline,Barboza Eliane Porto 대한영상치의학회 2022 Imaging Science in Dentistry Vol.52 No.1

Purpose: This cross-sectional study evaluated and categorized the tomographic sagittal root position (SRP) of the maxillary anterior teeth in a Brazilian population. Materials and Methods: Cone-beam computed tomographic scans of 420 maxillary anterior teeth of 70 patients (35 men and 35 women, mean age 25.2±5.9 years) were evaluated. The SRP was classified as class I, II, III, or IV. In class I, the root is positioned against the buccal cortical plate; in class II, the root is centered in the middle of the alveolar housing; in class III, the root is positioned against the palatal cortical plate; and in class IV, at least two-thirds of the root engage both the buccal and palatal cortical plates. Results: In total, 274 teeth (65.2%) were class I, 39 (9.3%) were class II, 3 (0.7%) were class III, and 104 (24.8%) were class IV. The frequency distribution over the teeth groups was different from the overall analysis. Important differences were found in the frequencies of classes I, II, and IV compared to other populations. Sex was not associated with the SRP classes (P= 0.307). Age distribution was significantly different over the classes (P= 0.004). Conclusion: The findings of this study on the distribution of SRP classes among the Brazilian population compared to other populations demonstrate that the SRP should be analyzed on a case-by-case basis for an accurate treatment plan in the maxillary anterior area.

Rapid thermal annealing induced modification in structural and electronic structure properties of Ti_0.95Co_0.05O_2@?δ thin films

Rodrigues, E.C.,Sharma, S.K.,de Menezes, A.S.,Chae, K.H.,Gautam, S.,Aljawf, R.N.,Kumar, S. Pergamon Press 2016 Materials research bulletin Vol.83 No.-

Thin film of Ti<SUB>0.95</SUB>Co<SUB>0.05</SUB>O<SUB>2-δ</SUB> was deposited on Si (100) using PLD method and annealed in O<SUB>2</SUB> and N<SUB>2</SUB> environment. Raman spectra confirm that all the films have rutile structure. Surface morphology indicates that the surface roughness and grain size increase with annealing. The electronic structure studied by NEXAFS spectroscopy at O K, Ti L<SUB>3,2</SUB> and Co L<SUB>3,2</SUB>-edges revealed that peak intensities decrease significantly for the film annealed N<SUB>2</SUB> environment. The ligand-field splitting estimated from the energy difference between the t<SUB>2g</SUB> and e<SUB>g</SUB> features in O K-edge spectra were 2.71eV for as-deposited and O<SUB>2</SUB> annealed film, whereas reduced more than double (@?1.32eV) for the film annealed in N<SUB>2</SUB>. Atomic multiplet calculations and experimentally observed NEXAFS spectra at Co L<SUB>3,2</SUB>-edge and Ti L<SUB>3,2</SUB>-edge confirm that Co present in 2+ and Ti in +4 valence state, whereas the multiplet structures of O<SUB>2</SUB> annealed film looks similar to Co metal.

The Impact of Preoperative Myelopathy on Postoperative Outcomes among Anterior Cervical Discectomy and Fusion Procedures in the Nonelderly Adult Population: A Propensity-Score Matched Study

Rodrigues Adrian John,Schonfeld Ethan,Varshneya Kunal,Stienen Martin Nikolaus,Veeravagu Anand 대한척추외과학회 2023 Asian Spine Journal Vol.17 No.4

Study Design: Retrospective cohort study.Purpose: Anterior cervical discectomy and fusion (ACDF) is a common surgical intervention for patients diagnosed with cervical degenerative diseases with or without myelopathy. A thorough understanding of outcomes in patients with and without myelopathy undergoing ACDF is required because of the widespread utilization of ACDF for these indications.Overview of Literature: Non-ACDF approaches achieved inferior outcomes in certain myelopathic cases. Studies have compared patient outcomes across procedures, but few have compared outcomes concerning myelopathic versus nonmyelopathic cohorts.Methods: The MarketScan database was queried from 2007 to 2016 to identify adult patients who were ≤65 years old, and underwent ACDF using the international classification of diseases 9th version and current procedural terminology codes. Nearest neighbor propensity-score matching was employed to balance patient demographics and operative characteristics between myelopathic and nonmyelopathic cohorts.Results: Of 107,480 patients who met the inclusion criteria, 29,152 (27.1%) were diagnosed with myelopathy. At baseline, the median age of patients with myelopathy was higher (52 years vs. 50 years, p <0.001), and they had a higher comorbidity burden (mean Charlson comorbidity index, 1.92 vs. 1.58; p <0.001) than patients without myelopathy. Patients with myelopathy were more likely to undergo surgical revision at 2 years (odds ratio [OR], 1.63; 95% confidence interval [CI], 1.54–1.73) or are readmitted within 90 days (OR, 1.27; 95% CI, 1.20–1.34). After patient cohorts were matched, patients with myelopathy remained at elevated risk for reoperation at 2 years (OR, 1.55; 95% CI, 1.44–1.67) and postoperative dysphagia (2.78% vs. 1.68%, p <0.001) compared to patients without myelopathy.Conclusions: We found inferior postoperative outcomes at baseline for patients with myelopathy undergoing ACDF compared to patients without myelopathy. Patients with myelopathy remained at significantly greater risk for reoperation and readmission after balancing potential confounding variables across cohorts, and these differences in outcomes were largely driven by patients with myelopathy undergoing 1–2 level fusions.

Maxillary first molar with 7 root canals diagnosed using cone-beam computed tomography

Rodrigues, Evaldo,Braitt, Antonio Henrique,Galvao, Bruno Ferraz,da Silva, Emmanuel Joao Nogueira Leal The Korean Academy of Conservative Dentistry 2017 Restorative Dentistry & Endodontics Vol.42 No.1

Root canal anatomy is complex, and the recognition of anatomic variations could be a challenge for clinicians. This case report describes the importance of cone beam computed tomographyic (CBCT) imaging during endodontic treatment. A 23 year old woman was referred by her general dental practitioner with the chief complaint of spontaneous pain in her right posterior maxilla. From the clinical and radiographic findings, a diagnosis of symptomatic irreversible pulpitis was made and endodontic treatment was suggested to the patient. The patient underwent CBCT examination, and CBCT scan slices revealed seven canals: three mesiobuccal (MB1, MB2, and MB3), two distobuccal (DB1 and DB2), and two palatal (P1 and P2). Canals were successfully treated with reciprocating files and filled using single-cone filling technique. Precise knowledge of root canal morphology and its variation is important during root canal treatment. CBCT examination is an excellent tool for identifying and managing these complex root canal systems.

Genetic parameters for worm resistance in Santa Inês sheep using the Bayesian animal model

Rodrigues, Francelino Neiva,Sarmento, Jose Lindenberg Rocha,Leal, Tania Maria,de Araujo, Adriana Mello,Filho, Luiz Antonio Silva Figueiredo Asian Australasian Association of Animal Productio 2021 Animal Bioscience Vol.34 No.2

Objective: The objective of this study was to estimate the genetic parameters for worm resistance (WR) and associated characteristics, using the linear-threshold animal model via Bayesian inference in single- and multiple-trait analyses. Methods: Data were collected from a herd of Santa Inês breed sheep. All information was collected with animals submitted to natural contamination conditions. All data (number of eggs per gram of feces [FEC], Famacha score [FS], body condition score [BCS], and hematocrit [HCT]) were collected on the same day. The animals were weighed individually on the day after collection (after 12-h fasting). The WR trait was defined by the multivariate cluster analysis, using the FEC, HCT, BCS, and FS of material collected from naturally infected sheep of the Santa Inês breed. The variance components and genetic parameters for the WR, FEC, HCT, BCS, and FS traits were estimated using the Bayesian inference under the linear and threshold animal model. Results: A low magnitude was obtained for repeatability of worm-related traits. The mean values estimated for heritability were of low-to-high (0.05 to 0.88) magnitude. The FEC, HCT, BCS, FS, and body weight traits showed higher heritability (although low magnitude) in the multiple-trait model due to increased information about traits. All WR characters showed a significant genetic correlation, and heritability estimates ranged from low (0.44; single-trait model) to high (0.88; multiple-trait model). Conclusion: Therefore, we suggest that FS be included as a criterion of ovine genetic selection for endoparasite resistance using the trait defined by multivariate cluster analysis, as it will provide greater genetic gains when compared to any single trait. In addition, its measurement is easy and inexpensive, exhibiting greater heritability and repeatability and a high genetic correlation with the trait of resistance to worms.
