Abstract:

Objective: To determine the difference in effectiveness of positional release therapy (PRT) compared with therapeutic massage (TM) in treating trigger and tender points in the upper trapezius muscle. Background: Trigger points in the upper trapezius muscle are common and can be painful. Therapeutic massage is a more traditional treatment method for this condition while PRT is relatively new. Design and Setting: A randomized-group design was used to examine the differences between the 2 treatments for reducing pain and muscle tension. Subjects: Sixty healthy subjects (males = 24, females = 36;

Abstract:

Side effects of current chemotherapeutics limit their use in cancer therapy. Although many current drugs are highly toxic and potent, the effects they have on non-cancerous tissue are unbearable for patients. Targeting these drugs may provide a means to restrict their toxic effects to only cancer tissue while leaving healthy tissue unaffected. This approach requires that the drug is only available in cancer tissue, which has been achieved here by encapsulating drugs into liposomal nano-capsules which are capable of passively accumulating in cancerous tissue via the enhanced permeability and re

L'encapsulation de médicaments est un domaine florissant où les améliorations thérapeutiques potentielles sont importantes. À cet égard, la capacité de contrôler la libération du médicament à l´aide des ultrasons est séduisante car elle permet de localiser et gérer l´administration du médicament. Dans mon projet de thèse, j´ai étudié la possibilité d´utiliser de faibles intensités ultrasonores pour contrôler la libération du médicament. Pour ce faire, j´ai utilisé des émulsions pour encapsuler deux types de médicaments : le « paclitaxel », un médicament anticancéreux, et la « lévofloxacine »,

L'hyperthermie sera appliquée au niveau de la tumeur, afin d'améliorer l’efficacité thérapeutique et de réduire la toxicité systémique.

We have used a lipid-based nanoemulsion termed Lipid-Oil-Nanodroplets (LONDs) for the encapsulation and in vivo delivery of the poorly bioavailable Combretastatin A4 (CA4). Drug delivery with CA4 LONDs was assessed in a xenograft model of colorectal cancer. LC-MS/MS analysis revealed that CA4 LONDs, administered at a drug dose four times lower than drug control, achieved equivalent concentrations of CA4 intratumorally. We then attached CA4 L

Medical ultrasound imaging is ubiquitous in clinics due to its safety, low cost, portability, and imaging depth. The development of technologies to assist ultrasound in the diagnosis of diseases thus have a potentially broad clinical impact. More recently, photoacoustics has emerged as a complementary, high contrast modality for imaging optical absorption. Injectable dyes and nanoparticles locally amplify ultrasound and photoacoustic signal, helping to identify disease markers and track its progression.
