Summary
Hyperthermia, using heat to treat infections, shows promise against antibiotic-resistant bacteria and biofilms. This approach offers new ways to combat challenging bacterial infections, especially those on implants.
Area of Science:
- Biomedical Engineering
- Infectious Diseases
- Therapeutic Technologies
Background:
- Bacterial infections pose significant clinical challenges, exacerbated by rising antibiotic resistance.
- Bacterial biofilms are notoriously difficult to eradicate with conventional treatments.
- Current antibiotic therapies are becoming less effective against resistant bacterial strains.
Purpose of the Study:
- To review the potential of hyperthermia as a therapeutic strategy against bacterial infections.
- To explore various thermal modalities for combating bacterial biofilms and antibiotic-resistant organisms.
- To highlight the clinical challenges posed by biofilm infections, particularly in soft tissues and on biomedical implants.
Main Methods:
- Review of existing literature on bacterial biofilms and their response to hyperthermia.
- Analysis of thermal treatment modalities including radiofrequency, ultrasound, and microwave thermotherapy.
- Evaluation of hyperthermia's efficacy when combined with photothermal and magnetic nanoparticles (NP).
Main Results:
- Hyperthermia can ablate bacteria or sensitize them to antimicrobial agents.
- Various thermal modalities demonstrate potential for controlling bacterial growth and biofilm formation.
- Nanoparticle-based hyperthermia offers targeted approaches for infection mitigation.
Conclusions:
- Hyperthermia presents a promising alternative or adjunct therapy for bacterial infections, especially those involving biofilms and antibiotic resistance.
- Further research into thermal modalities is crucial for developing effective treatments for challenging infections.
- Hyperthermia holds significant potential for mitigating bacterial infections and improving patient outcomes.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

03:03mTOR Signaling and Cancer Progression
4.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...

01:30Bacterial Signaling
41.3K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

00:43Bacterial RNA Polymerase
32.9K
Unlike eukaryotes, bacteria use a single RNA Polymerase (RNAP) to transcribe all genes. The different subunits of bacterial RNAPhave distinct functions. The multisubunit structure of the bacterial RNAP helps the enzyme to maintain catalytic function, facilitate assembly, interact with DNA and RNA, and self-regulate its activity.
In most genes, the transcription site is a single base present upstream of the coding sequence. Though RNAP is a catalytically efficient enzyme, it does not recognize...

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
