Antimicrobial chemotherapy and surgery are classical methods for treating infectious diseases. However, there is a need for alternative methods to cure infections caused by antibiotic-resistant pathogens, recurrent or chronic infections, and unreachable local infections in which the use of drugs or surgery is anatomically and physically restricted. Several microorganisms are known to be sensitive to mild hyperthermia, and this sensitivity is one of the potential benefits proposed for the host during an episode of fever...

The optimal light dose, heat generation, consequent heat spread, and an accurate thermal damage model, are key components of effective laser therapies. Recent advances in nanotechnology offer numerous possibilities on how to increase the efficacy of hyperthermia for tumour treatments. Gold nanoparticles are a promising candidate towards the achievement of this goal owing to their properties for efficiently converting light to heat. In this review, we summarise the numerical tools that are available for theoretical studies of gold-nanoparticle-mediated photo-thermal therapy...

This paper conducts the thermal analysis of magnetic fluid with superparamagnetic nanoparticles subjected to an alternating magnetic field. Magnetic fluid hyperthermia (MFH) provides a potential method for cancer treatment, which has fewer side effects than chemotherapy and radiotherapy. Superparamagnetic nanoparticles dispersed in water are suitable for safe application of MFH. A well-defined hyperthermia should only kill the cancer cells without injuring neighbouring normal tissue. A key factor for hyperthermia is to correctly control the alternating magnetic field-induced temperature of the magnetic fluid in the tumour...

The World Health Organization has approved magnetic nanoparticles (MNP) for use as a contrast agent for magnetic resonance imaging or tumor hyperthermia treatment. MNP are toxic over time after intra-testicular injection. A clear strategy to ameliorate the toxic side effects of MNP in normal tissues after medical application has not yet been developed. We used an extract of Echinacea purpurea (EP) as a natural source of antioxidant and free radical scavenging product for detoxification of MNP in testicular tissues...

LSD (lysergic acid diethylamide) was discovered almost 75 years ago, and has been the object of episodic controversy since then. While initially explored as an adjunctive psychiatric treatment, its recreational use by the general public has persisted and on occasion has been associated with adverse outcomes, particularly when the drug is taken under suboptimal conditions. LSD's potential to cause psychological disturbance (bad trips) has been long understood, and has rarely been associated with accidental deaths and suicide...

The use of targeted nanoparticles for magnetic hyperthermia (MHT) increases MHT selectivity, but often at the expense of its effectiveness. Consequently, targeted MHT is typically used in combination with other treatment modalities. This work describes an implementation of a highly effective monotherapeutic in vitro MHT treatment based on two populations of magnetic particles. Cells were sequentially incubated with two populations of magnetic particles: nonfunctionalized superparamagnetic nanoparticles and anti-CXCR4-functionalized particles...

Combination of multiple modalities has shown great potential in cancer treatment with improved therapeutic effects and minimized side effects. Here we fabricated a kind of doxorubicin encapsulated biomimetic nanovesicles (NVs) by a facile method with near-infrared dye insertion in the membrane for combinatorial photothermal and chemotherapy. With innate biomimetic properties, NVs enhanced the uptake by tumor cells while reduced the phagocytosis of macrophages. Upon laser irradiation, NVs can convert the absorbed fluorescent energy into heat for effective tumor killing...

Alleviation of tumor hypoxia has been the premise for improving the effectiveness of radiotherapy, which hinges upon the advanced delivery and rapid release of oxygen within the tumor region. Herein, we propose a "bubble-enhanced oxygen diffusion" strategy to achieve whole tumor oxygenation for significant radiation enhancement based on the "bystander effect". Towards this end, sub-50 nm CuS-modified and 64Cu labeled hollow mesoporous organosilica nanoparticles were constructed for tumor-specific delivery of O2-saturated perfluoropentane (PFP)...

Hyperthermia has been proposed as a promising treatment modality for its advantageous profiles such as mini/non-invasiveness, good tolerability, and cost-effectiveness. Quick development of nanotechnology in recent years has greatly broadened the application area of hyperthermia and endowed it with attractive new functions. Thermal sensitive nanostructures can absorb energy from an external source. They can control the therapeutic heating only in the targeted region without damage to normal tissues. They can also be loaded with therapeutic drugs and/or functionalized with imaging properties to construct multifunctional theranostic nanoplatforms...

Near-infrared photothermal therapy has been investigated extensively with regard to selective tumor eradication, yet its clinical translation has been limited due to the absence of FDA-approvable agents with effective phototherapeutic function and minimal systemic toxicity. In this work, we developed photothermally amplified therapeutic liposomes in an attempt to synergize chemotherapy and hyperthermia for effective cancer phototherapy. The anti-cancer drug cisplatin and the photothermal agent indocyanine green (ICG) were encapsulated in a thermo-sensitive liposomal formulation at the lipid/ICG ratio maximizing the ICG loading efficiency...
