Evaluation of the Efficacy of a Neem Extract-Based Herbal Ointment, Herbal Antioxidant, and Propolis on Oxidative Stress Related to Oral Ulcers: An Interventional Animal Study.

Unlabelled: Traumatic oral ulcers are one of the most commonly encountered oral ulcers. Their healing may be delayed due to factors like the presence of opportunistic infectious microbes in the oral cavity, secondary trauma from sharp edges of teeth, and the systemic condition of the patient.

Aim: To compare the efficacy of a newly developed neem extract containing herbal ointments (propolis and  in enhancing the wound contraction of traumatic oral ulcers and to determine the relationship between oxidative stress and oral ulcers.

Cyanobacteria and microalgae growing on monuments of UNESCO World Heritage site Champaner Pavagadh, India: biofilms and their exopolysaccharide composition.

The present study investigated the biofilm organisms growing on selected monuments of the Champaner Pavagadh complex (Gujarat, India), which is a UNESCO World Heritage Site. The cyanobacteria and microalgae were isolated from biofilms collected through non-destructive methods. The identification of these biological organisms was done using micro-morphological characters and confirmed by 16S rRNA gene sequencing.

A majority of uninfected adults show preexisting antibody reactivity against SARS-CoV-2.

Preexisting cross-reactivity to SARS-CoV-2 occurs in the absence of prior viral exposure. However, this has been difficult to quantify at the population level due to a lack of reliably defined seroreactivity thresholds. Using an orthogonal antibody testing approach, we estimated that about 0.

Antibody reactivity to SARS-CoV-2 is common in unexposed adults and infants under 6 months.

Background: Pre-existing antibody reactivity against SARS-CoV-2 in unexposed people is a potentially important consideration for COVID-19 severity and vaccine responses. However, it has been difficult to quantify due to a lack of reliable defined background titers in unexposed individuals.

Methods: We measured IgG against multiple SARS-CoV-2 antigens, SARS-CoV and other circulating coronavirus spike proteins using a highly sensitive multiplex assay, and total SARS-CoV-2 spike-specific antibodies (IgG/M/A) using a commercial CLIA assay in 276 adults from the Vancouver area, Canada between May 17th and June 19th 2020.

Continuation of Buprenorphine to Facilitate Postoperative Pain Management for Patients on Buprenorphine Opioid Agonist Therapy.

Background: Acute pain management in patients on buprenorphine opioid agonist therapy (BOAT) can be challenging. It is unclear whether BOAT should be continued or interrupted for optimization of postoperative pain control.

Objectives: To determine an evidence-based approach for pain management in patients on BOAT in the perioperative setting, particularly whether BOAT should be continued or interrupted with or without bridging to another mu opioid agonist and to identify benefits and harms of either perioperative strategy.

Scanning electron microscopic evaluation of smear layer removal at the apical third of root canals using diode laser, endoActivator, and ultrasonics with chitosan: An study.

Aim: The aim of this study was to compare the effect of diode laser, endoActivator, and passive ultrasonics for smear layer removal at the apical third from root canals with 0.2% chitosan.

Materials And Methods: A total of 40 mandibular premolars were decoronated to establish a working length of 12 mm and shaped with ProTaper rotary files up to size F3.

A comparative evaluation of shear bond strength of composite resin to pulp chamber dentin treated with sodium thiosulfate and proanthocyanidin: An study.

Aim: Based on the importance of coronal sealing right after endodontic treatment, this study aimed to evaluate the difference of shear bond strength to pulp chamber dentin treated with sodium thiosulfate and proanthocyanidin (PA).

Materials And Methods: Fifteen extracted mandibular molar teeth were decoronated at the level of cementoenamel junction horizontally. The individual teeth were then sectioned mesiodistally to expose the pulp chamber dentin using a diamond disc.

The Contribution of Indian Endodontists in Rotary Endodontics to Pubmed Database, from 2000-2017.

Aim: This study aimed at assessing the trends of publications of Indian Endodontists in the field of rotary Endodontics in the PubMed database from 2000-2017.

Methods: The date of publication was set from 1st January 2000 to 31st December 2017, wherein keywords entered in the advanced search were "Indian" AND "Dental" AND "Rotary Endodontics". From the collected articles the following criteria were noted: year of publication, the name of the journal, status of the journal, name of the first author, state of origin and the rotary Endodontic file system used.

Scanning Electron Microscopic Evaluation of Efficacy of 17% Ethylenediaminetetraacetic Acid and Chitosan for Smear Layer Removal with Ultrasonics: An Study.

Introduction: The main aim of root canal treatment is cleaning, shaping and then obturating three dimensionally to prevent reinfection. This includes chemicomechanical cleansing by instrumentation and the use of irrigating solutions. Therefore, the purpose of this study was to compare the smear layer removal from root canal dentine subjected to two root canal irrigants, 17% EDTA and 0.

Subclinical albuminuria is linked to gray matter atrophy in type 2 diabetes mellitus.

Objective: Microalbuminuria (MA), a marker of renal microvascular disease, is associated with brain atrophy and neurovascular changes in older adults with type 2 diabetes mellitus (DM). We evaluated the relationship between urine albumin-to-creatinine ratio (UACR) and regional brain volumes to determine whether subclinical albuminuria may indicate early structural brain changes in type 2 DM.

Materials/methods: We studied UACR and brain volumes in 85 type 2 DM patients (64.

Emergence delirium in children: a randomized trial to compare total intravenous anesthesia with propofol and remifentanil to inhalational sevoflurane anesthesia.

Background: Emergence delirium (ED) refers to a variety of behavioral disturbances commonly seen in children following emergence from anesthesia. Vapor-based anesthesia with sevoflurane, the most common pediatric anesthetic technique, is associated with the highest incidence of ED. Propofol has been shown to reduce ED, but these studies have been methodologically limited.

The effects of droperidol and ondansetron on dispersion of myocardial repolarization in children.

Objectives: To compare the effects of droperidol and ondansetron on electrocardiographic indices of myocardial repolarization in children.

Aim: To refine understanding of the torsadogenic risk to children exposed to anti-emetic prophylaxis in the perioperative period.

Background: QT interval prolongation is associated with torsades des pointes (TdP), but is a poor predictor of drug torsadogenicity.

The effect of age on the dose of remifentanil for tracheal intubation in infants and children.

Introduction: This study aimed to determine the age-specific bolus dose of remifentanil (ED(50)) to facilitate tracheal intubation without the use of neuromuscular blocking agents.

Methods: ASA 1-2 subjects were recruited into three groups of 0-3 months (group I), 4-12 months (group II), and 1-3 years (group III) of age. A sequential up-and-down design determined the remifentanil bolus dose, which was initially started at 3 mcg x kg(-1) and adjusted in 1 mcg x kg(-1) increments (range 1-6 mcg x kg(-1)).

The effect of a target controlled infusion of propofol on predictability of recovery from anesthesia in children.

Background: Emergence following termination of a general anesthetic depends on the effect site concentration (C(e)) of the drug declining to an awakening value (C(e)-awake). C(e)-awake has been described in adults, but is unknown in children.

Objectives: To determine C(e)-awake in children following a target-controlled infusion (TCI) of propofol and to assess a C(e)-driven TCI system's ability to predict times to emergence from anesthesia.

Target controlled infusion for kids: trials and simulations.

Target controlled infusion (TCI) for Kids is a computer controlled system designed to administer propofol for general anesthesia. A controller establishes infusion rates required to achieve a specified concentration at the drug's effect site (C(e)) by implementing a continuously updated pharmacokinetic-pharmacodymanic model. This manuscript provides an overview of the system's design, preclinical tests, and a clinical pilot study.
