Recent developments in therapeutic applications of atomic and nuclear radiations
In recent years, the major 'challenge' of radiation treatment is to deliver large enough doses to the most resistant cancer cells to provide a high probability of local control while minimising the dose to normal tissues and hence reducing complications. With recent developments in 'imaging' the metabolic or functional status of cancers, the position of tumours relative to surrounding normal ...

Mesoscopic studies on toxic effect of doxorubicin on rat cardiac muscles
The anthracycline antibiotic doxorubicin (DOX) is one of the most effective anti-tumour agents used to treat human malignancies. Long-term treatment with DOX is limited by its cardiotoxicity. The purpose of the present study was to evaluate the cardiotoxic effect of DOX using nanoscale. Twelve adult male rats were divided into two groups: control group, group 2A, DOX one week (DOX 1wk), group2B, ...

Gold nanoparticle–based platforms as cancer–targeted molecules delivery systems
Cancer is a major cause of deaths. More recently, drug delivery systems (DDSs) using gold nanoparticles (GNPs) have been widely developed in cancer therapy for their easily synthesised, functionalised, better biocompatible, and low toxicity properties. Gold nanoparticle–based platforms as cancer–targeted molecules delivery to tumour tissues have been proposed as an effective strategy by ...

Nanodrug potential in cancer therapy: efficacy/toxicity studies in cancer cells
The interest of nanotechnology to find a more effective approach for drug delivery is growing fast. Nanoparticles as drug vehicles potentially improve the pharmacokinetic and pharmacodynamic properties of various types of drugs, and provide a tool to visualise molecules and tumour target cells that otherwise cannot be detected through conventional imaging. However, there are many aspects of ...

Cancer stem–like cells photothermolysed by gold nanorod–mediated near–infrared laser irradiation
Several studies have recently identified CD133 as a marker of cancer stem–like cells (CSCs) for various tumours. Such findings make CD133 a potential molecular target for tumour–selective therapeutic approach. In this study, fluorescence–tagged CD133 monoclonal antibody (anti–CD133) was conjugated to gold nanorods (GNRs), which are one of the anisotropic nanomaterials that can absorb ...

Triiodophenyl acrylate–based microbeads find important use in the medical field
Preparation of polymeric micro– and nanoparticles has significantly become an effective approach for achieving efficient drug targeting to tumour tissues. A promising solution could be the use of a radio–opaque polymeric system carrying iodine groups. In this context, radio–opaque polymeric microparticles based on methyl methacrylate (MMA) and an 2,4,6–triiodophenyl acrylate (TIPA) were ...

Montreal-developed probe could be breakthrough in finding cancer (Montreal CTV News)
A fibre-optic probe can detect errant cancer cells within healthy tissue during brain tumour surgery with close to 100 per cent accuracy and sensitivity, reducing the risk of recurrence and thereby increasing a patient’s survival time, say the Canadian researchers who developed the device. The hand-held, pen-like instrument, known as a Raman spectroscopy probe, is able to differentiate ...

The correlation of hypersensitivity for HRS/IRR and the 'inverse' dose-rate effect – its potential influence on LDR brachytherapy: a review
The 'Inverse' Dose-Rate Effect (IDRE) has been extensively studied (Leonard, 2000; 2007a; Leonard and Lucas, 2008a?b). We here consolidate these results. We have shown a correlation between Hyper-radiosensitivity and the Induced Radioresistance effect (HRS/IRR), and IDRE has the same threshold and transition behaviours. This supports a conclusion that IDRE is the dose-rate manifestation of ...

Non–covalent surface integration: optimising a novel technique for preparing targeted polymeric nanoparticles for cancer therapeutics
Targeting anticancer drugs to their specific molecular targets is a major challenge in cancer therapy. However, advances in biomedical and protein engineering have led to novel nanoparticle targeting approaches. In this study, we used a novel non–covalent insertion of a homo–bifunctional spacer for targeted delivery of drugs to various cancer cells. Functionalised blank nanoparticles for antibody ...

WHO report on diesel fumes puts sharp focus on need for effective monitoring
The World Health Organisation this month reclassified the dangers of diesel exhaust fumes, upgrading the risk from probably carcinogenic to a definite cause of cancer. The WHO report is based on the findings of research on workers in high risk areas, and puts a sharp focus on the need for effective monitoring in industries such as mining, rail, transportation, construction, power generation and ...

Delivering a precision medicine programme at scale
The Covid-19 pandemic highlighted the disparity between those who succumbed to severe illness while others remained relatively unaffected, underscoring the urgent need to shift the healthcare industry’s focus from a one-size-fits-all approach to more personalised healthcare. Personalised medicine promises to transform healthcare with treatments tailored to a patient’s unique genetic ...

The Crucial Role of Cytokines in Biomedical Research and Drug Development
Low Endotoxin Cytokines Matters Organoid culture, CAR-T cell therapy, stem cell therapy, and other topics have become broadly discussed among biomedical researchers. In fact, it is not difficult to see that these advanced technologies are all related to cell culture. In order to maintain efficient growth, proliferation, and differentiation during in vitro cell culture, many cell cultures require ...
