1,3,5-Triformylphloroglucinol Derived β-Ketoenamine-Linked Functional Covalent Organic Frameworks with Enhanced Crystallinity and Stability-Recent Advances.

Crystallinity, stability, and complexity are significant factors to consider in the design and development of covalent organic frameworks (COFs). Among various building blocks used, 1,3,5-triformylphloroglucinol (Tp) is notable for enhancing both crystallinity and structural stability in COFs. Tp facilitates the formation of β-ketoenamine-linked COFs through keto-enol tautomerism when reacted with aromatic amines.

Assessment of Various Factors Contributing to Unfavourable Oral Health Care Seeking Behaviour: A Cross-Sectional Study.

Background:  Access to effective oral health care is crucial for a good quality of life. Unfortunately, many individuals face barriers in accessing the necessary oral health care services. By examining various factors, we can gain a better understanding of the challenges faced by the population and work towards improving oral health care outcomes.

Urolithins: The Colon Microbiota Metabolites as Endocrine Modulators: Prospects and Perspectives.

Selective estrogen receptor modulators (SERMs) have been used in hormone related disorders, and their role in clinical medicine is evolving. Tamoxifen and raloxifen are the most commonly used synthetic SERMs, and their long-term use are known to create side effects. Hence, efforts have been directed to identify molecules which could retain the beneficial effects of estrogen, at the same time produce minimal side effects.

Permanent Anterior Teeth Fractures and its Impact on Oral Health-Related Quality of Life among 8-15-Year-Old Schoolchildren of Chennai City - A Cross-Sectional Survey.

Background: Tooth fracture is not only a distressing experience on the physical level of a child, but it may also have an effect on emotional and psychological levels. This study aims to assess the permanent anterior teeth fractures and their impact on Oral Health-Related Quality of Life (OHRQoL) among 8-15-year-old schoolchildren of Chennai city.

Materials And Methods: Thirty schools were randomly selected by stratified random sampling.

Association of COL1A2 (PvuII) gene polymorphism with risk and severity of dental fluorosis - A case control study.

Introduction: Dental fluorosis is a foremost public health problem in many countries, including India. Very few studies investigated gene polymorphism and risk of dental fluorosis. Genetic polymorphisms in Collagen Type I, alpha 2 (COL1A2) gene, found to be linked with bone pathogenesis, may affect the tooth formation resulting in the vulnerability to dental fluorosis.

Comparative evaluation of salt water rinse with chlorhexidine against oral microbes: A school-based randomized controlled trial.

Background: Mouth rinse that is natural, safe, cost-effective, readily available and culturally acceptable is required as an adjunct to routine tooth brushing to combat dental diseases. The aim of present study was to compare the effectiveness of salt water rinse with chlorhexidine mouth rinse in reducing dental plaque and oral microbial count.

Materials And Methods: The Minimum Inhibitory Concentration (MIC) of salt water against S.

Simulation of path delay multiplexing-based Fourier transform spectrometer for fiber Bragg grating interrogation.

A Fourier transform spectrometer (FTS) used for interrogating a fiber Bragg grating (FBG) consists of a scanning-type interferometer. The FTS has a broad wavelength range of operation and good multiplexing capability. However, it has poor wavelength resolution and interrogation speed.

Reconstructing the regulatory network controlling commitment and sporulation in Physarum polycephalum based on hierarchical Petri Net modelling and simulation.

We reconstruct the regulatory network controlling commitment and sporulation of Physarum polycephalum from experimental results using a hierarchical Petri Net-based modelling and simulation framework. The stochastic Petri Net consistently describes the structure and simulates the dynamics of the molecular network as analysed by genetic, biochemical and physiological experiments within a single coherent model. The Petri Net then is extended to simulate time-resolved somatic complementation experiments performed by mixing the cytoplasms of mutants altered in the sporulation response, to systematically explore the network structure and to probe its dynamics.

A simple rapid procedure for obtaining axenic cultures from monoxenic cultures of myxomycete plasmodia.

Axenic culture of myxomycete plasmodia has been attempted from time to time by various authors, but with very little success. From over 500 known species of myxomycetes, fewer than 20 species have been reported in axenic culture to date, including axenic myxamoebal cultures. In these cultures, the plasmodia required either complex media, or a killed bacterial supplement for growth.
