Simulation of an Orthodontic System Using the Lingual Technique Based on the Finite Element Method.

The finite element method (FEM) is an advanced numerical technique that can be applied in orthodontics to study tooth movements, stresses, and deformations that occur during orthodontic treatment. It is also useful for simulating and visualizing the biomechanical behavior of teeth, tissues, and orthodontic appliances in various clinical scenarios. The objective of this research was to analyze the mechanical behavior of teeth, tissues, and orthodontic appliances in various clinical scenarios.

Therapeutic Role of Secondary Metabolites from Probiotic Strains for Ehrlich Solid Tumors in Mice.

Forty-four male albino EST mice were assigned into 7 groups and treated daily for 2 weeks, including the EST group, the EST mice that received SE-WC at a low or a high dose (0.5 ml *10 or 0.

Orthodontic System Modeled and Simulated with the Lingual Technique to Assess Tooth Forces.

CBCT (cone beam computed tomography) is an imaging investigation that provides three-dimensional (3D) images of craniofacial structures. The purpose of this study is to determine the mechanical behavior of an orthodontic system where the lingual treatment technique was used in a 25-year-old female patient from whom a set of CBCT scans was used. CBCT images were processed through software programs such as Invesalius, Geomagic, and Solid Works, to create models containing virtual solids.

Expert opinion on management of moderate-to-severe atopic dermatitis in Qatar.

Atopic dermatitis (AD), a chronic-relapsing inflammatory skin disorder, manifests with intense itching and eczematous lesions impairing quality of life. A heterogeneous population, and regional clinical practices for treating AD warrant the development of guidelines in Qatar. Therefore, guidelines for the management of moderate-to-severe AD in Qatar have been developed and discussed.

Mental wellbeing of frontline health workers post-pandemic: lessons learned and a way forward.

Objective: To assess the state of mental wellbeing among medical and dental frontline health workers as the COVID-19 pandemic transitions to an endemic phase and to determine what employer-provided intervention strategies these workers perceive as effective and desirable to improve their mental wellbeing.

Methods: An anonymous online survey distributed to frontline health workers in a hospitalist program of a tertiary care medical center and a university dental school in Minnesota in September 2022. The survey contained validated tools to measure depression severity, levels of perceived stress, and mental health status as well as questions to determine effective strategies to improve emotional wellbeing among these health workers.

Comparison of Preprosthetic Implant Complications and Failures Between Obese and Nonobese Patients.

Treatment of hyperprolactinemia: a systematic review and meta-analysis.

Background: Hyperprolactinemia is a common endocrine disorder that can be associated with significant morbidity. We conducted a systematic review and meta-analyses of outcomes of hyperprolactinemic patients, including microadenomas and macroadenomas, to provide evidence-based recommendations for practitioners. Through this review, we aimed to compare efficacy and adverse effects of medications, surgery and radiotherapy in the treatment of hyperprolactinemia.

Context: Osteoporosis and osteopenia are associated with increased fracture incidence.

Objective: The aim of this study was to determine the comparative effectiveness of different pharmacological agents in reducing the risk of fragility fractures.

Data Sources: We searched multiple databases through 12/9/2011.

The association of hypertriglyceridemia with cardiovascular events and pancreatitis: a systematic review and meta-analysis.

Background: Hypertriglyceridemia may be associated with important complications. The aim of this study is to estimate the magnitude of association and quality of supporting evidence linking hypertriglyceridemia to cardiovascular events and pancreatitis.

Neovascularization of the amniotic membrane as a biological immune barrier.

The clinical application of islet transplantation is limited due to the limited source and the morbidity of systemic immunosuppression to prevent rejection. The two problems can be solved by using encapsulated islets. We have used amniotic membranes as biocompatible natural immune barriers.

Genetic polymorphism by RAPD-PCR and phenotypic characteristics of isolated thermotolerant Bacillus strains from hot spring sources.

The polymerase chain reaction (PCR) based random amplified polymorphic DNA (RAPD) assay, morphological, physiological, biochemical and antimicrobial susceptibility test methods have been evaluated for use in the taxonomy of isolated thermotolerant Bacillus from Jordanian hot springs, with specific reference to strains Geobacillus stearothermophilus (ATCC 12980), Bacillus circulans (ATCC 4513) and Bacillus sphaericus (ATCC 14577). A RAPD assay has been optimized and is able to discriminate between numerous thermotolerant Bacillus strains. RAPD-PCR was found to give reproducible thermotolerant Bacillus strains classification of DNA fingerprints for 14 strains including 3 reference strains.

Motility of three strains of Proteus mirabilis (G9, P11 and PM5C) in liquid suspension under different environmental conditions.

The effect of compounds on the motility of Proteus mirabilis swarmer cells varies from one strain to another. The effect of compounds on the motility of swarmer cells is mainly at higher concentrations than the concentration used to inhibit swarming. Boric acid only affects the motility of strain G9 swarmer cells, whereas sodium deoxycholate prevented the motility of swarmer cells for three strains.

Effects of temperatures, pH-values, ultra-violet light, ethanol and chloroform on the growth of isolated thermophilic Bacillus phages.

Seven thermophilic Bacillus phages were characterized with reference to their host range, time of appearance, morphology of plaques, thermal inactivation, stability, lipid presence and inactivation by ultraviolet irradiation. Response surface methodology was adapted to describe the response of growth parameters to environmental changes. Most phages are susceptible to temperatures above 60 degrees C and inactivated immediately at 103 degrees C.
