Effects of online marketplace-sourced over-the-counter tooth whitening products on the colour, microhardness, and surface topography of enamel: an in vitro study.

Objectives: This study compared the whitening effect, microhardness, and enamel surface alterations of over-the-counter (OTC) tooth bleaching products with those of a dentist-prescribed at-home bleaching agent.

Materials And Methods: The products available on a popular online marketplace were comprehensively searched and then rated using a specific formula. The effects of the lowest-rated OTC agent (LRA) and the highest-rated OTC agent (HRA) were compared with those of a dentist-prescribed bleaching agent (DPA) on the enamel of extracted human teeth.

Acute Exposure to Bisphenol S Decreases In Vitro Right Atrial Contractility in Rats.

Aim/objective: Bisphenols are widely used in the manufacturing of polycarbonate material and epoxy resins which constitute the essential component of plastic. Bisphenol A (BPA) has been reported to produce toxicity on organs in both animal and human studies. Therefore, plastic manufacturers are replacing BPA with other analogues that are considered to be safe, and BPA-free products are now available in the market.

Toxicity of Bisphenol in Pregnant Females: First Review of Literature in Humans.

Bisphenol analogues are widely used in consumer products such as disposable dinnerware, canned food, personal care products, bottled beverages, and more, and dietary exposure is the main pathway. Bisphenol A is used to manufacture synthetic resins and commercial plastics in large quantities. According to epidemiological and animal studies, bisphenols disrupt the reproductive, immunological, and metabolic systems.

Pathogenesis of Cardiomyopathy Caused by Variants in , an Essential Pseudokinase in the Cardiomyocyte Nucleus and Sarcomere.

Background: encodes α-kinase 3, a muscle-specific protein of unknown function. loss-of-function variants cause cardiomyopathy with distinctive clinical manifestations in both children and adults, but the molecular functions of ALPK3 remain poorly understood.

Methods: We explored the putative kinase activity of ALPK3 and the consequences of damaging variants using isogenic human induced pluripotent stem cell-derived cardiomyocytes, mice, and human patient tissues.

Evaluation of immunocytochemistry on destained giemsa stained smears as an alternative to conventional technique.

Introduction: Protocol for immunocytochemical (ICC) staining in May-Grünwald Giemsa (MGG)-stained smears has been difficult to establish. It is the need of the hour to be able to use prestained slides for ICC in specific cases to deliver timely diagnoses and reduce inconvenience to patients.

Aims And Objectives: To evaluate and compare the use of MGG-stained smears for the purpose of ICC, after de-staining and saline rehydration to that of routine standard ICC.

Optimization of a stochastic model having erratic server with immediate or delayed repair.

The thought to put forward a queuing model proposed in this work was its pertinence in everyday life wherever we can see the uses of computing and networking systems. Industrial software developers and system managers can consider the results of the model to evolve their system for better results. Here we present a novel queueing model having erratic server with delayed repair and balking.

USG Guided Fine Needle Aspiration Cytology along with Immunocytochemistry to Diagnose Primary Malignant Mixed Mullerian Tumors: A Three-Year Study from a Tertiary Care Center.

Aims And Objectives: To study the diagnostic utility of fine-needle aspiration cytology (FNAC) and immunocytochemistry in diagnosing primary malignant mixed Mullerian tumors (MMMT).

Materials And Methods: A 3-year retrospective study carried out in a tertiary care hospital, which included all the gynecological patients who underwent USG-guided FNAC of their abdominopelvic masses.

Observations And Results: Out of the 324 total cases, 05 (1.

Evaluation of diallelic STR markers with inter-population allelic database for their usefulness in paternity trios in the Central Indian population.

Background: Most of the forensic DNA laboratories have migrated to new generation STR kits of 6 dye chemistry with more than 20 autosomal STRs. The population-specific databases of such STR markers are lacking in many regions.

Aim: To evaluate the effect of the inter-population database in 100 paternity trios with no inconsistencies at 23 STRs.

Human Gut Microbiome: A New Frontier in Cancer Diagnostics & Therapeutics.

The field of oncology is vast and ever-growing. The present cancer therapeutics is continually exhibiting various drawbacks, which opens the door for exploring better novel therapeutic techniques. One such emerging technique is the manipulation of gut microbiota to induce a positive curative effect in the body.

Acinic cell carcinoma of the parotid gland with neuroendocrine differentiation.

Acinic cell carcinoma (ACC) is a malignant salivary gland tumor characterized by tumor cells displaying acinar features. Usually presenting as a slow-growing tumor, ACC, however, may show dedifferentiation to a higher grade including neuroendocrine carcinoma. In addition, ACC may rarely show focal neuroendocrine differentiation without any frank evidence of neuroendocrine carcinoma.

Filamin C Cardiomyopathy Variants Cause Protein and Lysosome Accumulation.

Utility of fine needle aspiration cytology to diagnose intraoral lymphoma: 7 years study from a tertiary care center.

Objective: Fine needle aspiration (FNA) cytology has been successfully utilized in the preoperative diagnosis of oral masses. Lymphoma involving other sites has also been diagnosed frequently on FNA. Oral cavity lymphoma (OL) is rare and is clinically indistinguishable from other lesions of the mouth.

Expression of vascular endothelial growth factor, CD10, and factor 8 in phyllodes tumor: A 5-year study of 38 cases.

Introduction: Phyllodes tumor is a group of biphasic fibroepithelial tumors of the breast, graded as benign, borderline, and malignant. The grading of breast phyllodes remains a challenging task for the pathologists as the prognosis, and further treatment depends on it. In this study, an effort has been made to grade phyllodes tumor on the basis of immunohistochemistry.

Localized cutaneous infection caused by Scedosporium apiospermum: Report of a case diagnosed on cytology.

Scedosporium apiospermum (also known as Pseudallescheria boydii) is a ubiquitous filamentous fungus. This fungus is known as a cause of mycetoma, which may occur in a normal immune host following trauma and nonmycetoma-localized skin infections without grain production which are much rarer. However, in an immunocompromised host, S.

mutations in hiPSCs inform mechanisms for maldevelopment of the heart, pancreas, and diaphragm.

Damaging variants cause cardiac outflow tract defects, sometimes with pancreatic and diaphragmic malformations. To define molecular mechanisms for these diverse developmental defects, we studied transcriptional and epigenetic responses to loss of function (LoF) and missense variants during cardiomyocyte differentiation of isogenic human induced pluripotent stem cells. We show that GATA6 is a pioneer factor in cardiac development, regulating that activates and that with orchestrates outflow tract formation.

Expanding the clinical and genetic spectrum of ALPK3 variants: Phenotypes identified in pediatric cardiomyopathy patients and adults with heterozygous variants.

Introduction: Biallelic damaging variants in ALPK3, encoding alpha-protein kinase 3, cause pediatric-onset cardiomyopathy with manifestations that are incompletely defined.

Methods And Results: We analyzed clinical manifestations of damaging biallelic ALPK3 variants in 19 pediatric patients, including nine previously published cases. Among these, 11 loss-of-function (LoF) variants, seven compound LoF and deleterious missense variants, and one homozygous deleterious missense variant were identified.

Myosin Sequestration Regulates Sarcomere Function, Cardiomyocyte Energetics, and Metabolism, Informing the Pathogenesis of Hypertrophic Cardiomyopathy.

Background: Hypertrophic cardiomyopathy (HCM) is caused by pathogenic variants in sarcomere protein genes that evoke hypercontractility, poor relaxation, and increased energy consumption by the heart and increased patient risks for arrhythmias and heart failure. Recent studies show that pathogenic missense variants in myosin, the molecular motor of the sarcomere, are clustered in residues that participate in dynamic conformational states of sarcomere proteins. We hypothesized that these conformations are essential to adapt contractile output for energy conservation and that pathophysiology of HCM results from destabilization of these conformations.
