Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene

Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene

Bromination and chlorination of aromatic rings by electrophilic aromatic substitution reactions are easily achieved, but fluorination and iodination are difficult to achieve. Fluorine is so reactive that its reaction with benzene is difficult to control, resulting in poor yields of monofluoroaromatic products. To address this, Selectfluor reagent is used as a fluorine source in which a fluorine atom is bonded to a positively charged nitrogen.

Filtration and Urine Formation

Filtration and Urine Formation

The function of the kidneys is to filter, reabsorb, secrete, and excrete. Every day the kidneys filter nearly 180 liters of blood, initially removing water and solutes but ultimately returning nearly all filtrates into circulation with the help of osmoregulatory hormones. This process removes wastes and toxins but is also crucial to maintain water and electrolyte levels. Most of these functions are performed by the tiny but numerous nephrons contained within the kidneys.

Fluid Mosaic Model

Fluid Mosaic Model

Scientists identified the plasma membrane in the 1890s and its principal chemical components (lipids and proteins) by 1915. The model for plasma membrane structure, proposed in 1935 by Hugh Davson and James Danielli, was the first model to be widely accepted in the scientific community. The model was based on the plasma membrane's "railroad track" appearance in early electron micrographs. Davson and Danielli theorized that the plasma membrane's structure resembled a sandwich...

The Fluid Mosaic Model

The Fluid Mosaic Model

The fluid mosaic model was first proposed as a visual representation of research observations. The model comprises the composition and dynamics of membranes and serves as a foundation for future membrane-related studies. The model depicts the structure of the plasma membrane with a variety of components, which include phospholipids, proteins, and carbohydrates. These integral molecules are loosely bound, defining the cell’s border and providing fluidity for optimal function.

FISH - Fluorescent In-situ Hybridization

FISH - Fluorescent In-situ Hybridization

Fluorescence in situ hybridization, or FISH, was developed in the early 1980s and has quickly become one of the most widely used techniques in cytogenetics. Labeled probes are used to bind complementary DNA or RNA sequences on a chromosome or in a region within a cell. Earlier, the probes could only be obtained by cloning or reverse transcription of a DNA template. Currently, the probe oligonucleotides can be synthesized synthetically. Additionally, with the advancement of optical techniques,...

Modeling in Therapy

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
Participant Modeling
Participant modeling involves therapists demonstrating calm and effective behaviors in...

Area of Science:

Infodemiology and Infoveillance
Social Media Analysis
Public Health Communication

Background:

Social media can spread health misinformation but also reveal social factors behind negative beliefs.
Data mining is crucial in infodemiology for combating misinformation.
Limited research exists on fluoride misinformation specifically on Twitter, despite concerns about fluoridated products.

Purpose of the Study:

To analyze the topics and temporal frequency of "fluoride-free" tweets.
To understand the drivers and nature of antifluoridation discourse online.

Main Methods:

Utilized Twitter API to collect 21,169 "fluoride-free" tweets (May 2016-May 2022).
Applied Latent Dirichlet Allocation (LDA) topic modeling to identify key themes.
Analyzed topic similarity, manually reviewed representative tweets, and visualized temporal trends using Elastic Stack.

Main Results:

Identified three main topics: "healthy lifestyle," "natural/organic oral care products," and "recommendations for fluoride-free alternatives."
Topic 1 focused on health concerns and fluoride toxicity; Topic 2 on natural product preferences; Topic 3 on promoting fluoride-free products and water.
Tweet volume decreased from 2016-2019, then increased from 2020 onwards, correlating with health and natural product trends.

Conclusions:

Increased "fluoride-free" tweets are motivated by healthy lifestyle concerns and adoption of natural products, potentially fueled by misinformation.
Public health authorities, professionals, and policymakers need to address the spread of fluoride-free content online to mitigate potential population health risks.
