Assessment of Correlation between Genetic Taste Perception Hormonal Fingerprint and Dental Caries Incidence in Schoolgoing Children: An In Vivo Study.

Background: Genetic predilection toward sweeter cariogenic foods mediated by the TAS2R38 gene, tested by phenylthiourea [phenylthiocarbamide (PTC)] compounds. Some individuals find it extremely bitter whereas some find it completely tasteless, being classified as a taster and a nontaster respectively. A majority of nontasters prefer foods with sweeter and stronger flavors, thus making them more susceptible to dental caries. Genetic taste perception is greatly influenced by prenatal androgen exposure represented by hormonal fingerprint, that is, ratio of second to fourth digit lengths (2D:4D ratio), thus making it a precise biomarker to quantify an individual's genetic taste perception and in turn their caries susceptibility. Aim: To find a correlation of genetic taste perception with the hormonal fingerprint and dental caries prevalence in children. Materials and methods: A total of 96 children were selected at random for the study and divided into two groups based on their gender. A genetic taste perception test was carried out using PTC strips, and they were classified as tasters and nontasters. Then, the hormonal fingerprint was recorded by calculating the ratio of the index finger and ring finger. Following this, decayed, missing, and filled teeth index (DMFT) was recorded. Results: A strong positive correlation was observed among nontasters, with a preference for sweeter foods associated with a high caries index. Conversely, no relationship was found between genetic taste perception and the hormonal fingerprint. Conclusion: The present study positively demonstrates an association of genetic taste perception and dental caries due to an increased preference for sweeter foods among nontasters. Although no correlation was found between the genetic taste perception, the hormonal fingerprint, and the dental caries status of an individual.

The Rare Case Presentation of Adult-Onset Fulminant Subacute Sclerosing Panencephalitis in a 24-Year-Old Male.

Subacute sclerosing panencephalitis (SSPE) is a late effect of measles in children. Its features include seizures, a gradual loss of physical and cognitive function, and finally death. Despite the absence of a definitive cure for this disorder, a regimen combining intrathecal interferon-α (IFN-α) and daily oral isoprinosine has demonstrated effectiveness. We present the case of a 24-year-old male with spastic seizure epilepsy. He exhibited progressive weakness, frequent postural instability, and recurrent generalized tonic-clonic seizures. Increased measles antibody concentrations in the cerebrospinal fluid (CSF), prominent amplitude spikes on the electroencephalogram (EEG), and heightened fluid-attenuated inversion recovery (FLAIR) signals on brain magnetic resonance imaging (MRI) suggested a diagnosis of SSPE.

Comparative Evaluation of Antimicrobial Efficacy of Triple Antibiotic Paste Herbal Combination and Camphorated Monochlorophenol as Intracanal Medicaments against Enterococcus faecalis in Deciduous Molars: An In Vivo Study.

Aim: Compare the efficacy of triple antibiotic paste (TAP), herbal extracts, and camphorated monochlorophenol (CMCP) as intracanal medicaments against Enterococcus faecalis (E. faecalis) in deciduous molars. Materials and methods: A total of 60 samples were collected from canals of first and second molars of 4-10-year-old children, with more than two-thirds root length, and fitting the inclusion criteria. Samples were collected at three intervals-S1 was collected just after access opening, S2 was collected after biomechanical preparation (BMP) and irrigation, and just before placement of medicament. Randomization was done to place the medicaments into three groups: group I-CMCP, group II-TAP, and group III-herbal combination. Sample S3 was taken 48 hours after removal of medicament from the canals. The collected samples were transported via Amies media to the laboratory, where they were anaerobically incubated for 24 hours. Growth of E. Faecalis was observed, and manual counting of the colony-forming unit (CFU) was done. The change in CFU in all samples was calculated, and the results were statistically analyzed. Results: The results show that there is a change from S1 (TAP = 118.67 ± 122.48, herbal = 109.07 ± 106.43; CMCP = 110.73 ± 120.53) to S2 (TAP = 34.13 ± 63.47; herbal = 27.67 ± 39.39; CMCP = 16.40 ± 26.32) and S3 (TAP = 12.33 ± 24.82; herbal = 4.73 ± 12.78; CMCP = 3.40 ± 7.12). It is seen that there is a significant difference seen from S1 to S2 in all three groups (p ≤ 0.05) using repeated measure analysis of variance (ANOVA) test. This shows that all three medicaments were effective in reducing bacterial counts of E. Faecalis from sample S1 (pre) to S3 (post) significantly after exposure to root canal bacterial flora for 48 hours (2 days). The pairwise comparison of the change in CFU within each group, S1-S3, also shows significant changes. There is a significant decrease in CFU seen from S1 to S2 and S1 to S3 but not from S2 to S3 for all three groups, which was evaluated using the post hoc Bonferroni test. It was also observed that in between the canals, although there was a change from S1 to S3 in terms of the CFU, there was no significant difference in the decrease in the bacterial count when intercanal comparison was made. There was, however, a change that was seen to be significant when values from each canal were compared from S1 to S3. Conclusion: All three medicaments have successfully shown a decrease in the numbers of E. faecalis, which the study aimed at checking. Although the effect varied intergroups, it was mild, so herbal alternatives could be used instead of antibiotics and CMCP. Also, because the local application is effective in controlling interappointment flare-ups, the medicaments can be successfully given without having to prescribe systemic antibiotics.

Electrical impedance measurements can identify red blood cell-rich content in acute ischemic stroke clots ex vivo associated with first-pass successful recanalization.

Background: Electrochemical impedance spectroscopy can determine characteristics such as cell density, size, and shape. The development of an electrical impedance-based medical device to estimate acute ischemic stroke (AIS) clot characteristics could improve stroke patient outcomes by informing clinical decision making. Objectives: To assess how well electrical impedance combined with machine learning identified red blood cell (RBC)-rich composition of AIS clots ex vivo, which is associated with a successfully modified first-pass effect. Methods: A total of 253 clots from 231 patients who underwent thrombectomy in 5 hospitals in France, Japan, Serbia, and Spain between February 2021 and October 2023 were analyzed in the Clotbase International Registry. Electrical impedance measurements were taken following clot retrieval by thrombectomy, followed by Martius Scarlet Blue staining. The clot components were quantified via Orbit Image Analysis, and RBC percentages were correlated with the RBC estimations made by the electrical impedance machine learning model. Results: Quantification by Martius Scarlet Blue staining identified RBCs as the major component in clots (RBCs, 37.6%; white blood cells, 5.7%; fibrin, 25.5%; platelets/other, 30.3%; and collagen, 1%). The impedance-based RBC estimation correlated well with the RBC content determined by histology, with a slope of 0.9 and Spearman's correlation of r = 0.7. Clots removed in 1 pass were significantly richer in RBCs and clots with successful recanalization in 1 pass (modified first-pass effect) were richer in RBCs as assessed using histology and impedance signature. Conclusion: Electrical impedance estimations of RBC content in AIS clots are consistent with histologic findings and may have potential for clinically relevant parameters.

Corrigendum to Contractility defects hinder glycoprotein VI-mediated platelet activation and affect platelet functions beyond clot contraction [Research and Practice in Thrombosis and Haemostasis Volume 8, Issue 1, January 2024, 102322].

Contractility defects hinder glycoprotein VI-mediated platelet activation and affect platelet functions beyond clot contraction.

Background: Active and passive biomechanical properties of platelets contribute substantially to thrombus formation. Actomyosin contractility drives clot contraction required for stabilizing the hemostatic plug. Impaired contractility results in bleeding but is difficult to detect using platelet function tests. Objectives: To determine how diminished myosin activity affects platelet functions, including and beyond clot contraction. Methods: Using the myosin IIA-specific pharmacologic inhibitor blebbistatin, we modulated myosin activity in platelets from healthy donors and systematically characterized platelet responses at various levels of inhibition by interrogating distinct platelet functions at each stage of thrombus formation using a range of complementary assays. Results: Partial myosin IIA inhibition neither affected platelet von Willebrand factor interactions under arterial shear nor platelet spreading and cytoskeletal rearrangements on fibrinogen. However, it impacted stress fiber formation and the nanoarchitecture of cell-matrix adhesions, drastically reducing and limiting traction forces. Higher blebbistatin concentrations impaired platelet adhesion under flow, altered mechanosensing at lamellipodia edges, and eliminated traction forces without affecting platelet spreading, α-granule secretion, or procoagulant platelet formation. Unexpectedly, myosin IIA inhibition reduced calcium influx, dense granule secretion, and platelet aggregation downstream of glycoprotein (GP)VI and limited the redistribution of GPVI on the cell membrane, whereas aggregation induced by adenosine diphosphate or arachidonic acid was unaffected. Conclusion: Our findings highlight the importance of both active contractile and passive crosslinking roles of myosin IIA in the platelet cytoskeleton. They support the hypothesis that highly contractile platelets are needed for hemostasis and further suggest a supportive role for myosin IIA in GPVI signaling.

Platelet mechanosensing as key to understanding platelet function.

PURPOSE OF REVIEW: This review highlights how the perception of platelet function is evolving based on recent insights into platelet mechanobiology. RECENT FINDINGS: The mechanosensitive ion channel Piezo1 mediates activation of free-flowing platelets under conditions of flow acceleration through mechanisms independent of adhesion receptors and classical activation pathways. Interference with the initiation of platelet migration or with the phenotypic switch of migrating platelets to a procoagulant state aggravates inflammatory bleeding. Mechanosensing of biochemical and biophysical microenvironmental cues during thrombus formation feed into platelet contractile force generation. Measurements of single platelet contraction and bulk clot retraction show promise to identify individuals at risk for hemorrhage. SUMMARY: New findings unravel novel mechanotransduction pathways and effector functions in platelets, establishing mechanobiology as a pivotal component of platelet function. These insights highlight limitations of existing treatments and offer new potential therapeutic approaches and diagnostic avenues based on mechanobiological principles. Further extensive research is required to distinguish between core hemostatic and pathological mechanisms influenced by platelet mechanosensing.

Environmental tobacco smoke and children's health: a bibliometric and altmetric analysis of 100 most cited articles.

BACKGROUND: Exposure to environmental tobacco smoke (ETS) is arguably the most ubiquitous and hazardous, even at very low levels, starting in early life. The objective of this study was to describe the state of research and future trends on ETS exposure and Children's Health (CH) topics with bibliometrics and altmetrics. METHODS: An electronic search was performed in Scopus database on January 31, 2023. Consensus was arrived on 100 most-cited articles by two reviewers. These papers were then cross matched with citations harvested from Web of Science (WoS) and Google Scholar. Altmetric Attention Score (AAS) and Dimension counts were also collected. Analysis and network visualization of authors, countries, and keywords were generated using VOSviewer software. RESULTS: Among a total of 1107 articles published on ETS and CH, the 100 top-cited articles appeared in 54 journals, with Pediatrics (n = 12) contributing a maximum number of articles. The time period between 2000 and 2009 accounted for 44% of all publications. With respect to the research design employed across these studies, cross-sectional design took precedence over others accounting for approximately 40%. Predominantly, articles focused on childhood asthma; however, current research trends have shifted towards emerging fields such as children's oral health and DNA methylation. Twitter, policy documents, and news outlets were the main platforms where outputs were discussed. The AAS was not associated with journal impact factor or access type. Weak correlations were observed between AAS and citation count in Scopus, WoS, and Google Scholar (r = 0.17 to 0.27) while a positive association existed between dimension count and the number of citations across all three databases (r = 0.84 to 0.98). CONCLUSION: This study demonstrates the evolution, digital dissemination and research hotspots in the field of ETS and CH, predicting the possible future research directions. High-quality studies with more specific exposure classification are warranted to better understand the relationship between ETS and CH.

Identifying ex vivo acute ischemic stroke thrombus composition using electrochemical impedance spectroscopy.

BACKGROUND: Intra-procedural characterization of stroke thromboemboli might guide mechanical thrombectomy (MT) device choice to improve recanalization rates. Electrochemical impedance spectroscopy (EIS) has been used to characterize various biological tissues in real time but has not been used in thrombus. OBJECTIVE: To perform a feasibility study of EIS analysis of thrombi retrieved by MT to evaluate: (1) the ability of EIS and machine learning to predict red blood cell (RBC) percentage content of thrombi and (2) to classify the thrombi as "RBC-rich" or "RBC-poor" based on a range of cutoff values of RBC. METHODS: ClotbasePilot was a multicentric, international, prospective feasibility study. Retrieved thrombi underwent histological analysis to identify proportions of RBC and other components. EIS results were analyzed with machine learning. Linear regression was used to evaluate the correlation between the histology and EIS. Sensitivity and specificity of the model to classify the thrombus as RBC-rich or RBC-poor were also evaluated. RESULTS: Among 514 MT,179 thrombi were included for EIS and histological analysis. The mean composition in RBC of the thrombi was 36% ± 24. Good correlation between the impedance-based prediction and histology was achieved (slope of 0.9, R2 = 0.53, Pearson coefficient = 0.72). Depending on the chosen cutoff, ranging from 20 to 60% of RBC, the calculated sensitivity for classification of thrombi ranged from 77 to 85% and the specificity from 72 to 88%. CONCLUSION: Combination of EIS and machine learning can reliably predict the RBC composition of retrieved ex vivo AIS thrombi and then classify them into groups according to their RBC composition with good sensitivity and specificity.

Assessment of the Changes in the Salivary Profile and Its Clinical Correlation in Children with Acute Lymphoblastic Leukemia Undergoing Chemotherapy: A Follow-up Study.

Aim: To assess the changes in salivary profile and its clinical correlation in patients with acute lymphoblastic leukemia (ALL) undergoing chemotherapy. Materials and methods: Children who have been diagnosed with ALL undergoing chemotherapy at Bharati Hospital, Pune, were included in the study. Those children were included who fulfilled the following inclusion and exclusion criteria. Stimulated salivary samples were collected in sterile vials at 1-, 3-, and 6-month intervals and ware assessed for salivary pH and buffering capacity. Caries and oral manifestations were also checked at each interval. Results: A total of 25 children with ALL undergoing chemotherapy were included to participate in the study. The results were analyzed using Statistical Package for the Social Sciences software. There was a statistically significant difference in the change in salivary pH during the 1st and 6th months of chemotherapy (p-value of 0.001). Salivary buffering capacity was also found to be low in these patients during the 1st month of chemotherapy, which gradually increased during the entire course of chemotherapy (p-value of 0.011). Progression of dental caries was seen during the entire course of treatment. Conclusion: All the major changes were seen in the 1st month, that is, the induction phase of chemotherapy. Hence, we can say this is the most affected phase of chemotherapy. Clinical significance: The parents and children should be educated and motivated to maintain proper oral hygiene. Whenever possible, all preventive dental procedures should be undertaken before the start of chemotherapy to avoid future complications.

Year-round sustainable biomass production potential of Nannochloris sp. in outdoor raceway pond enabled through strategic photobiological screening.

Microalgae cultivation utilizes the energy of sunlight to reduce carbon dioxide (CO2) for producing renewable energy feedstock. The commercial success of the biological fixation of carbon in a consistent manner depends upon the availability of a robust microalgae strain. In the present work, we report the identification of a novel marine Nannochloris sp. through multiparametric photosynthetic evaluation. Detailed photobiological analysis of this strain has revealed a smaller functional antenna, faster relaxation kinetics of non-photochemical quenching, and a high photosynthetic rate with increasing light and temperatures. Furthermore, laboratory scale growth assessment demonstrated a broad range halotolerance of 10-70 parts per thousand (PPT) and high-temperature tolerance up to 45 °C. Such traits led to the translation of biomass productivity potential from the laboratory scale (0.2-3.0 L) to the outdoor 50,000 L raceway pond scale (500-m2) without any pond crashes. The current investigation revealed outdoor single-day peak areal biomass productivity of 43 g m-2 d-1 in summer with an annual (March 2019-February 2020) average productivity of 20 g m-2 d-1 in seawater. From a sustainability perspective, this is the first report of successful round-the-year (> 347 days) multi-season (summer, monsoon, and winter) outdoor cultivation of Nannochloris sp. in broad seawater salinity (1-57 PPT), wide temperature ranges (15-40 °C), and in fluctuating light conditions. Concurrently, outdoor cultivation of this strain demonstrated conducive fatty acid distribution, including increased unsaturated fatty acids in winter. This inherent characteristic might play a role in protecting photosynthesis machinery at low temperatures and in high light stress. Altogether, our marine Nannochloris sp. showed tremendous potential for commercial scale cultivation to produce biofuels, food ingredients, and a sustainable source for vegetarian protein.

Comparison of the Influence of a Packaged Fruit Juice on the Bacterial Adhesion on a Glass Ionomer Cement and an Esthetic Restorative Material In Vitro.

Objective: The aim of this research was to evaluate and compare the effect of a packaged orange juice on the two most commonly used restorative materials in pediatric dentistry. Methodology: Fifteen samples each of 6 mm diameter and 2 mm thickness of a glass ionomer cement (GIC) and an esthetic restorative material were prepared using silicone rings. These were exposed to a packaged orange fruit juice and then placed in a standard culture of Streptococcus mutans. The bacterial adhesion to these samples was evaluated after exposure to the fruit juice for 1 day and for 7 days. Results: Results from the study show that there is a decrease in the colony forming unit (CFU) after exposure to the packaged fruit juice as opposed to the studies using carbonated acidic drinks, which have shown a consistent rise in the CFU due to a change in the surface morphology. Conclusion: Within the limitations of this study, it was seen that the consumption of fruit juice may not cause a deteriorating effect on the restorative materials considered. However, the results were not statistically significant and further research is necessary to come to a conclusion regarding the reduction in the bacterial count after exposure to the fruit juice. Clinical implications: With further research, such studies can help in improving the diet counseling practices. How to cite this article: Patel A, Belsare SP, Jajoo SS, et al.

A CBCT assessment of bone density changes after accelerated orthodontic retraction of canine by microosteoperforations.

AIM: The study was conducted to assess the changes in bone density before and after performing accelerated orthodontic maxillary canine retraction by microosteoperforations (MOPs). MATERIALS AND METHODS: Forty patients (120 cone-beam computed tomography [CBCT] images) within the age group of 15 to 25 years undergoing fixed orthodontic treatment with bilateral maxillary first premolar extraction were enrolled in this study. The right and left sides of the maxillary jaw in the same patients were selected as experimental and control sites. To accelerate the tooth movement, MOPs were performed distal to the canine root in the extraction space under local anesthesia with a miniscrew. Thereafter, the maxillary canine retraction was initiated using a NiTi closed coil spring. The CBCT images were taken and evaluated at the following time intervals: 1 week before MOPs(T0);1 week after MOPs(T1);3 weeks after MOPs(T2). RESULTS: A statistically significant reduction in bone density was observed at the center of resistance of canine on the experimental site (after MOPs) at 1 week and 3 weeks (T0-T1 = 0.000,0.115; T1-T2 = 0.0025,0.0117), whereas a statistically non-significant difference was found 1 week before and 3 weeks later in the control group. CONCLUSION: Accelerated orthodontics by MOPscan result in a substantial reduction in bone density during canine retraction, leading to an increase in the tooth movement rate, hence lowering the overall orthodontic treatment time.

Characterising acute ischaemic stroke thrombi: insights from histology, imaging and emerging impedance-based technologies.

Treatment of acute ischaemic stroke (AIS) focuses on rapid recanalisation of the occluded artery. In recent years, advent of mechanical thrombectomy devices and new procedures have accelerated the analysis of thrombi retrieved during the endovascular thrombectomy procedure. Despite ongoing developments and progress in AIS imaging techniques, it is not yet possible to conclude definitively regarding thrombus characteristics that could advise on the probable efficacy of thrombolysis or thrombectomy in advance of treatment. Intraprocedural devices with dignostic capabilities or new clinical imaging approaches are needed for better treatment of AIS patients. In this review, what is known about the composition of the thrombi that cause strokes and the evidence that thrombus composition has an impact on success of acute stroke treatment has been examined. This review also discusses the evidence that AIS thrombus composition varies with aetiology, questioning if suspected aetiology could be a useful indicator to stroke physicians to help decide the best acute course of treatment. Furthermore, this review discusses the evidence that current widely used radiological imaging tools can predict thrombus composition. Further use of new emerging technologies based on bioimpedance, as imaging modalities for diagnosing AIS and new medical device tools for detecting thrombus composition in situ has been introduced. Whether bioimpedance would be beneficial for gaining new insights into in situ thrombus composition that could guide choice of optimum treatment approach is also reviewed.

Comparative Evaluation of Water Sorption, Solubility, and Microhardness of Zirconia-reinforced Glass Ionomer, Resin-modified Glass Ionomer, and Type IX Glass Ionomer Restorative Materials: An In Vitro Study.

The challenge that practicing dentists face every day is to decide which dental material is best suited for each dental treatment. New glass-ionomer cement (GIC) formulations have been introduced in order to overcome the drawbacks of conventional ones thereby catering to the needs of the pediatric population. Aim and objective: The study aimed to evaluate and compare water sorption, solubility, and microhardness of zirconia-reinforced glass ionomer, resin-modified glass ionomer, type IX glass ionomer cements. Materials and methods: 90 specimens were prepared in total of which 45 cylindrical specimens with dimensions of (6 × 4) mm and 45 disks with (10 × 2) mm were prepared from Zirconomer, RMGIC, and Type IX GIC restorative materials, each material having 30 specimens (15 disks, 15 cylinders). After taking the initial weight (W1), the 45 cylinders (15 of each material) were immersed in artificial saliva at 37°C for 28 days after which the weights W2 and W3 were weighed. The other 45 disks (15 of each material) were subjected to microhardness test under microhardness tester. Results were subjected to ANOVA and Tuckey's post hoc test. Results: Zirconomer showed the maximum resistance to water sorption and solubility followed by RMGIC and type IX GIC with a significant p value of < 0.001 difference. For microhardness, Zirconomer showed the highest value with a significant p value of < 0.001 difference. But, there was no significant difference between RMGIC and Type IX GIC depicting almost equal strength. Conclusion: Water sorption, solubility, and microhardness of Zirconomer were significantly high in comparison to the other groups and it can be used as a posterior restorative material for stress-bearing areas. Clinical Significance: As pediatric dentistry demands restorations to be completed frequently in less than ideal conditions, Zirconomer has shown to be better than RMGIC and conventional GIC probably because of the improvisation in the GIC properties.

Radicular Cyst Involving Deciduous Maxillary Incisor along with Bilateral Supernumerary Teeth: A Case Report.

Radicular cyst involving the deciduous dentition is rare. Most of the cases reported it with primary molar teeth with apical infection. But very rare literature is available regarding radicular cysts associated with primary incisors. Case report: A case of 9-year-old boy, who had bilaterally impacted supernumerary teeth, had developed a radicular cyst associated with a previously traumatized and intruded right upper primary lateral incisor is reported. Supernumerary teeth and intruded primary lateral incisor were removed along with enucleation of a radicular cyst. Conclusion: The importance of correct diagnosis and management of radicular cyst in pediatric patients is important as most of the radicular cysts of primary teeth go undiagnosed, which can affect the developing succedaneous tooth bud.

Comparative Evaluation of the Remineralization Potential of Fluoride-containing Toothpaste, Honey Ginger Paste and Ozone. An In Vitro Study.

Introduction: A drop in pH of the oral cavity results in demineralization, which, if continued, leads to loss of minerals from tooth structure, resulting in dental caries. A goal of modern dentistry is to manage noncavitated caries lesions noninvasively through remineralization in an attempt to prevent disease progression. Materials and methods: A total of 40 extracted premolar teeth were selected for the study. The specimens were divided into four groups, group I, the control group; group II, remineralizing agent as fluoride toothpaste; group III, the treatment material as ginger and honey paste; and group IV, the treatment material as ozone oil. An initial reading of surface roughness and hardness was recorded for the group (control group). Repeated treatment has continued lasting 21 days. This saliva was changed each day. Following the lesion formation procedure, the surface microhardness was measured for all specimens. The parameters were 200 gm force for 15 seconds with a Vickers indenter and the roughness of the demineralized area of each specimen was obtained by using the surface roughness tester. Results: Surface roughness was checked by using a surface roughness tester. Before starting the pH cycle, the baseline value for the control group was calculated. The baseline value for the control group was calculated. The surface roughness average value for 10 samples is 0.555 µm and the average surface microhardness is 304 HV; the average surface roughness value for fluoride is 0.244 µm and the microhardness is 256 HV, 0.241 µm, and 271 HV value for honey-ginger paste. For ozone surface roughness average value is 0.238 µm and the surface microhardness average mean value is 253 HV. Conclusion: The future of dentistry will rely on the regeneration of tooth structure. There is no significant difference seen between each treatment group. Considering the adverse effect of fluoride, we can consider honey-ginger and ozone as good remineralizing agents for fluoride.
