Recent Advances of VO in Sensors and Actuators.

Vanadium dioxide (VO) stands out for its versatility in numerous applications, thanks to its unique reversible insulator-to-metal phase transition. This transition can be initiated by various stimuli, leading to significant alterations in the material's characteristics, including its resistivity and optical properties. As the interest in the material is growing year by year, the purpose of this review is to explore the trends and current state of progress on some of the applications proposed for VO in the field of sensors and actuators using literature review methods.

Pseudomonas putida infection induces immune-antioxidant, hepato-renal, ethological, and histopathological/immunohistochemical disruptions in Oreochromis niloticus: the palliative role of titanium dioxide nanogel.

Background: Pseudomonas putida is a pathogenic bacterium that induces great losses in fishes, including Nile tilapia (Oreochromis niloticus). Currently, the application of nanomaterials in aquaculture practices has gained more success as it endows promising results in therapies compared to traditional protocols.

Objective: Therefore, the current perspective is considered the first report to assess the anti-bacterial efficacy of titanium dioxide nanogel (TDNG) against Pseudomonas putida (P.

Novel Tetrahydro-[1,2,4]triazolo[3,4-]isoquinoline Chalcones Suppress Breast Carcinoma through Cell Cycle Arrests and Apoptosis.

Chalcones are interesting anticancer drug candidates which have attracted much interest due to their unique structure and their extensive biological activity. Various functional modifications in chalcones have been reported, along with their pharmacological properties. In the current study, novel chalcone derivatives with the chemical base of tetrahydro-[1,2,4]triazolo[3,4-a]isoquinolin-3-yl)-3-arylprop-2-en-1-one were synthesized, and the structure of their molecules was confirmed through NMR spectroscopy.

Determinants of COVID-19 Vaccine Acceptance among Dental Professionals: A Multi-Country Survey.

Purpose: This study sought to investigate the acceptance rate and associated factors of COVID-19 vaccines among dentists and dental students in seven countries.

Material And Methods: A structured questionnaire prepared and guided by the report of the SAGE Working Group on Vaccine Hesitancy was distributed among groups of dentists and dental students in seven countries across four continents.

Results: A total of 1527 subjects (850 dentists and 677 dental students) participated in this survey.

Effect of Denture Adhesives on Adhesion of to Denture Base Materials: An Study.

Aim And Objective: This study aimed to investigate the adhesion of (CA) to the surface of the denture base using two different types of resins after exposure to denture adhesives (DAs).

Materials And Methods: Twenty-five samples of polymethyl methacrylate (PMMA) and 25 samples of urethane dimethacrylate (UDMA) (10 mm × 10 mm × 2 mm) were prepared and allocated to 10 groups (five samples in each group). For each type of denture base materials, four test groups were immersed for 30 days in four commercially available DAs in addition to water as control group.

Potential Effects of Anthocyanin-Rich Roselle ( L.) Extract on the Growth, Intestinal Histomorphology, Blood Biochemical Parameters, and the Immune Status of Broiler Chickens.

The potential effects of anthocyanin-rich roselle, L. extract (ARRE) on the growth, carcass traits, intestinal histomorphology, breast muscle composition, blood biochemical parameters, antioxidant activity, and immune status of broiler chickens were evaluated. In the present study, acidified ethanolic extract was reported to have a total anthocyanin content of about 359.

A Global Survey of COVID-19 Vaccine Acceptance Among Healthcare Workers.

Objectives: Even though several effective vaccines are available to combat the COVID-19 pandemic, wide disparities in vaccine distribution, and vaccine acceptance rates between high- and low-income countries appear to be major threats toward achieving population immunity. Our global descriptive study aims to inform policymakers on factors affecting COVID-19 vaccine acceptance among healthcare workers (HCWs) in 12 countries, based on income index. We also looked for possible predictors of vaccine acceptance among the study sample.

A Survey of Dentists' Perception of Chair-Side CAD/CAM Technology.

The application of computer-aided design and computer-aided manufacturing (CAD/CAM) technology in dentistry has rapidly expanded. This survey aimed to investigate attitudes and current practice of dentists in Riyadh, Saudi Arabia regarding chair-side CAD/CAM technology. An online questionnaire was prepared and sent to a convenience sample of dentists in Riyadh.

Could photodynamic therapy be utilized as a treatment modality for oral lichen planus?

Background: Oral lichen planus (OLP) is a chronic inflammatory disease. There is no standard treatment modality for OLP. Recently, photodynamic therapy (PDT) has been advocated as a new treatment modality for OLP.

The Perceptions of Dentists Working in Saudi Arabia of the Utility of Different Restoration Options for a Shortened Dental Arch in Patients of Different Ages.

Purpose: This study aimed to assess dentists' views of the utility of an unrestored shortened dental arch (SDA) compared to the utility of various prosthetic treatment options.

Materials And Methods: A total of 142 dentists working at four sites in Riyadh, Saudi Arabia, were interviewed and presented with 18 scenarios for patients of different ages with SDAs that lost molar teeth. Participants were asked to indicate on a standardized visual analog scale (VAS) how they would value the health of the patient's mouth if the SDAs were left unrestored or restored with five prosthetic dental restorations.

Reasons for choosing dentistry as a career among dental students in Saudi Arabia.

Objective: This study aimed to identify reasons and influential factors for choosing dentistry as a career among dental students in Saudi Arabia. The preferred field of dental specialty following graduation will also be investigated.
