The Utility of Salivary Heme to Stratify Healthy Volunteers from Individuals with Gingivitis and Periodontitis: a Pilot Study
Authors: Sreenivasan Prem K. , Nandlal Bhojraj , Aruna Ganganna , Madhunapantula S. , McBain Andrew J. 
Published: March 2024

Summary
Gingival bleeding due to poor oral hygiene is reported globally. Assessment of blood in saliva may improve diagnostics, serve as an outcome measure in clinical trials and support patient education through point-of-care tests. This work analyzed salivary heme using a rapid test format and separately using a lateral flow immunoassay assay [LF] for chair-side implementation. Clinical examinations stratified adult subjects into healthy, gingivitis or periodontitis groups at baseline. Healthy subjects presented no periodontal pockets and whole mouth gingivitis scores of less than 1.0. Gingivitis subjects registered gingival index scores greater than 1.0. Included in the periodontal disease group were subjects with periodontal pockets greater than 4 mm. The rapid test is based on the peroxidase activity salivary heme converting a colourless probe to a coloured compound for spectrophotometric analysis. For the LF assay, saliva was placed in the test window of the device with reactions scored after room temperature incubation. Average salivary heme concentrations in the healthy, gingivitis and periodontal disease groups were 27, 201 and 326 nM respectively, by the rapid test, representing significant differences by analysis of variance and Tukey’s-multiple comparison tests (p<0.05). Similarly, results in the LF assay demonstrated increasing band intensity from the healthy to the periodontal disease groups and was quantifiable by image analysis. This pilot study emphasizes the potential efficacy of rapid heme measurement in investigations of oral health.

Effect of immediate dentin sealing on the fracture strength of lithium disilicate ceramic onlays
Authors: Saadeddin Nader , Ali Al-Khalil Manar , Al-Adel Omar 
Published: March 2024

Summary
This study aimed to evaluate the effect of immediate dentin sealing (IDS) on the fracture strength of ceramic onlays when compared with delayed dentin sealing (DDS). Twenty extracted human maxillary premolars were randomly divided into 2 groups according to the dentin sealing technique (n=10). A standardized mesio-occlusal-distal cavity was prepared with reduction of the palatal cusp. The dentin surfaces of the IDS group were immediately sealed after finishing the preparation (before taking impressions, temporization, and 14-day storage at 37°C) using a bonding system (ALL-BOND 3®, ALL-BOND 3® RESIN) and flowable composite (Te-Econom Flow). Impressions were made and temporary restorations were fabricated using PRO-V FILL®. The wax patterns were milled and the onlays were fabricated by heat-pressing technique (IPS e.max Press). After bonding the final restorations with resin cement (Variolink N), the specimens were thermocycled. Fracture strength was measured using a universal testing machine (Testometric M350-10KN) at 1 mm/min until failure occurred. Student's t-test was used to evaluate the results of the fracture strength test. The failure mode was examined using a stereomicroscope. The mean fracture strength in the IDS group (1335 ± 335 N) was statistically significantly higher than that for the DDS group (931 ± 274 N) (p < 0.05). Fracture of the restoration with a small portion of the tooth was the most frequent mode of failure. Within the limitation of this in vitro study, there was an improvement in the fracture strength of ceramic onlays with the use of IDS. However, the ceramic onlays were strong enough to withstand the physiological mastication force in both groups.

Published: March 2024

Oral healthcare among the frail is an underestimated geriatric care element. While neglected oral health (OH) is a well-established risk factor for frailty, frailty can be a risk factor for subsequent OH problems.
The cross-sectional investigation nested into the SAPALDIA sub-cohort of citizens aged 52 years and older, aims to stimulate longitudinal research into aspects that accelerate poor OH among frail individuals. The hypothesis investigated was that (pre-) frail individuals are more likely to have missing teeth replaced with removable dental prostheses (RDP) resulting in difficulties with chewing.
The study included 1489 participants undergoing geriatric assessments and oral examination. The main predictor was frailty status (non-frail; pre-frail; frail), based on Fried’s frailty phenotype. The main outcomes of interest were non-functional dentition (presence of ≤ 19 natural teeth), presence of any RDP and self-reported difficulties with chewing.
Pre-frailty and frailty were not associated with the presence of ≤ 19 natural teeth, but were associated with a higher RDP prevalence. The presence of at least one complete denture (CD) had 1.71 fold and 2.54 folds higher odds among pre-frail and frail, respectively, compared to non-frail individuals. Frail individuals with CD reported chewing difficulties 7.8 times more often than non-frail individuals without CD.
The results are in line with the hypothesis that (pre-) frail individuals may be more likely to have tooth loss restored by RDPs. Future longitudinal research needs to assess potential barriers to oral hygiene and fixed dental prostheses among (pre-) frail and to study their oral health-related quality of life.
Les fantômes des esclaves nous murmurent à l’oreille : pas de futur sans reconnaissance du passé
Authors: Thermitus Tamara 
Published: March 2024

Comme le disait James Baldwin, « L’histoire n’est pas le passé, c’est le présent. Nous portons notre histoire en nous. » Ainsi, l’esclavage est inscrit dans l’ADN des corps noirs, il fait partie de leur histoire.
Ayant commencé sa vie d’artiste sous le nom de SAMO (Same Old Shit) patronyme illustrant les traumatismes du racisme marquant les âmes noires. Cet éternel jeune homme nous interpelle : comment parler du futur, lorsqu’on ne peut se débarrasser des fantômes du passé ?
En me fondant sur la Critical Race Theory, approche qui prend notamment en compte l’expérience du racisme anti-noir, j’analyserai certaines œuvres cruciales de Basquiat, porteuses de récits, pour appréhender la société. Ces œuvres nous parlent toujours en faisant de Basquiat un prophète.
Dans Water-Worshipper, (1984), il expose l’esclavage et rompt le silence en exposant les séquelles sociales écrasantes et implacables.
Et comment ignorer sa clairvoyance alors qu’il nous parle dans Defacment?(1983) de Michael Stewart qui est une illustration des traitements des corps noirs, cette œuvre nous parle aujourd’hui des noirs assassinés, de George Floyd.
Ce que nous enseigne Basquiat : pas de futur sans reconnaissance du passé.

Problème de Recherche : L’hypertension artérielle est une maladie chronique et multifactorielle. Elle atteint près du tiers de la population adulte en Tunisie et représente l’un des motifs de consultation les plus fréquents et un important facteur de risque des maladies cardiovasculaires et d’accidents vasculaires cérébraux.
Plusieurs facteurs organiques, psychologiques et environnementaux sont incriminés dans l’apparition et l’équilibre de l’hypertension artérielle. Parmi les facteurs psychosociaux, la dépression est présente chez 26,8% des patients hypertendus avec une lourde morbi-mortalité cardiovasculaire.
L’objectif de ce travail est d’étudier le lien entre l’équilibre tensionnel et la dépression masquée dans une population de patients hypertendus ambulatoire.
Processus d’investigation : Il s'agit d'une étude transversale descriptive prospective multicentrique. Trois cents deux patients hypertendus ambulatoires seront inclus. Les patients bénéficiant d’une mesure ambulatoire de 24 heures de la pression artérielle dans le cadre de l’évaluation de l’équilibre tensionnel rempliront un questionnaire en dialecte tunisien (score Patient Health Questionnaire-9 PHQ-9) pour dépister la dépression et évaluer sa sévérité. Les données socio environnementales, cliniques, thérapeutiques et pronostiques seront recueillies des dossiers médicaux. Les patients seront classés en deux groupes : HTA équilibrée versus non-équilibrée. Les scores PHQ-9 seront ensuite comparés entre les deux cohortes.
Plan de Recherche : Les considérations éthiques seront entreprises et respectées. Le consentement éclairé oral est recueilli pour chaque patient. L’étude se déroulera durant trois mois à partir du 15 août 2022.

Aims: The American Cancer Society,s estimates for brain and spinal cord tumors in the United States for 2023, include both adults and children,25,400 malignant tumors will be diagnosed. The objective of this study was to analyze the epidemiological profile, risk factors for complications and death in the in-hospital postoperative period, in addition to describing the histological type of intracranial tumors most frequently operated on in a private Brazilian institution.
Study Design: Retrospective cohort study.
Place and Duration of Study: Biocor Instituto/Rede D’Or, from 2018 to 2021
Methodology: Data were collected from the medical records of patients who underwent surgery for intracranial tumors. The variables analyzed in this study were demographic characteristics (age, sex, and comorbidities), histological types of primary and secondary neoplasms, anatomical location of the lesions, neurological deficits at admission and post-surgical treatment (at discharge), whether the surgery was urgent or elective, whether it was a reoperation, and whether there were deaths or complications during hospitalization.
Results: Of 242 patients, 11 patients were excluded, and 231 patients were included in the analysis. The most common histological type was meningioma, accounting for 28% of cases. The histological type most associated with the risk of death was hemangioblastoma; however, it was also the histological type that presented the lowest incidence of cases. 39 patients (17%) had some complication in the in-hospital postoperative period, and 14 patients (6%) died.
Conclusions: Meningiomas constituted the majority of cases, accounting for 28% of the sample. The rate of complications and mortality was higher when compared to data from the international literature because this series analyzed brain metastases together with the excision of primary tumors. Concerning in-hospital deaths, hemangioblastoma emerged as the histological type most associated with the risk of death. It is noteworthy, however, that hemangioblastoma also exhibited the lowest incidence among the various histological types.
The Position of Children's Characters in Children's Animation Postcolonialism Studies
Authors: Zahrok Siti , Isnah Encik Savira , Marsudi Marsudi , Hendrajati Enie , Subali Edy , Wahyudin Wahyudin 
Published: March 2024

Children's literature has now begun to shift to digital media, known as children’s animation. Instead of children's literature being created for children, these works are written, edited and distributed by adults. This shows that adults (parents) have full power over the work that children will consume. Colonialism theory then questions what it means to write for children. This research appears with the real assumption of where the child is positioned in children’s cyber literature. The postcolonial approach is used to verify this assumption. The results show that children are treated as objects, a means to endure real problems faced by adults. It appears that writing for children in addition to exploring is also stuffing and imposing the will for the needs of adults: guiding children, training children through the process of reaching civilization which is again the power of adults to define it.
Interactions of Neutral and Cationic Transition Metals with the Redox System of Hydroquinone and Quinone: Theoretical Characterization of the Binding Topologies, and Implications for the Formation of Nanomaterials
Authors: Yi Hai‐Bo , Diefenbach Martin , Choi Young Cheol , Lee Eun Cheol , Lee Han Myoung , Hong Byung Hee , Kim Kwang S. 
Published: May 2006

AbstractTo understand the self‐assembly process of the transition metal (TM) nanoclusters and nanowires self‐synthesized by hydroquinone (HQ) and calix[4]hydroquinone (CHQ) by electrochemical redox processes, we have investigated the binding sites of HQ for the transition‐metal cations TMn+=Ag+, Au+, Pd2+, Pt2+, and Hg2+ and those of quinone (Q) for the reduced neutral metals TM0, using ab initio calculations. For comparison, TM0–HQ and TMn+–Q interactions, as well as the cases for Na+ and Cu+ (which do not take part in self‐synthesis by CHQ) are also included. In general, TM–ligand coordination is controlled by symmetry constraints imposed on the respective orbital interactions. Calculations predict that, due to synergetic interactions, silver and gold are very efficient metals for one‐dimensional (1D) nanowire formation in the self‐assembly process, platinum and mercury favor both nanowire/nanorod and thin film formation, while palladium favors two‐dimensional (2D) thin film formation.
