Chronic Lymphocytic Leukemia: A Review Of Front-Line Treatment Options, With A Focus On Elderly Cll Patients, Alma O'Reilly, James Murphy, Sarah Rawe, Mary Garvey
Chronic Lymphocytic Leukemia: A Review Of Front-Line Treatment Options, With A Focus On Elderly Cll Patients, Alma O'Reilly, James Murphy, Sarah Rawe, Mary Garvey
Articles
Chronic lymphocytic leukemia (CLL) remains the most prevalent form of leukemia in the Western world, with no cure to date. Ongoing and essential research into this heterogeneous disease has led to a number of new treatment options becoming available to CLL patients in the past decade. The present review presents the recent developments in the field of CLL treatment, with the main focus on elderly patients and CLL patients with coexisting comorbidities. The review discusses the current treatment regimens that provide the most promising outcomes for patients in this subgroup, with a number of important clinical trials summarized. These clinical …
Toxicology Of Engineered Nanoparticles: Focus On Poly(Amidoamine) Dendrimers, Pratap Naha, Sourav Prasanna Mukherjee, Hugh Byrne
Toxicology Of Engineered Nanoparticles: Focus On Poly(Amidoamine) Dendrimers, Pratap Naha, Sourav Prasanna Mukherjee, Hugh Byrne

Engineered nanomaterials are increasingly being developed for paints, sunscreens, cosmetics, industrial lubricants, tyres, semiconductor devices, and also for biomedical applications such as in diagnostics, therapeutics, and contrast agents. As a result, nanomaterials are being manufactured, transported, and used in larger and larger quantities, and potential impacts on environmental and human health have been raised. Poly(amidoamine) (PAMAM) dendrimers are specifically suitable for biomedical applications. They are well-defined nanoscale molecules which contain a 2-carbon ethylenediamine core and primary amine groups at the surface. The systematically variable structural architecture and the large internal free volume make these dendrimers an attractive option for drug …

There is an unmet need for methods to help in the early detection of cervical precancer. Optical spectroscopy-based techniques, such as Raman spectroscopy, have shown great potential for diagnosis of different cancers, including cervical cancer. However, relatively few studies have been carried out on liquid-based cytology (LBC) pap test specimens and confounding factors, such as blood contamination, have been identified. Previous work reported a method to remove blood contamination before Raman spectroscopy by pretreatment of the slides with hydrogen peroxide. The aim of the present study was to extend this work to excessively bloody samples to see if these could …

Raman spectroscopy is a powerful tool that has the potential to be used as a screening method for cervical cancer. It is a label-free, low-cost method providing a biochemical fingerprint of a given sample. The objective of this study was to address patient-to-patient variability contributed by hormonal effects due to the menstrual cycle, the use of hormone-based contraceptives (HC) and the onset of menopause, and to determine if these changes would affect the ability to successfully identify dyskaryotic cells. Raman spectra were recorded from unstained ThinPrep cervical samples (45 cytology negative and 15 high-grade dyskaryosis (high-grade squamous intraepithelial lesion, HSIL) …

The dissolution of microporous silica nanoparticles (NP) in aqueous environments of different biologically relevant pH was studied in order to assess their potential as drug delivery vehicles. Silica NPs, loaded with fluorescein, were prepared using different organosilane precursors (tetraethoxysilane, ethyl triethoxysilane or a 1:1 molar ratio of both) and NP dissolution was evaluated in aqueous conditions at pH 4, pH 6 and pH 7.4. These conditions correspond to the acidity of the intracellular environment (late endosome, early endosome, cytosol respectively) and gastrointestinal tract (‘fed’ stomach, duodenum and jejunum respectively). All NPs degraded at pH 6 and pH 7.4, while no …

Due to the side-effects caused by regular chemotherapy, the development of drug delivery systems that can specifically target cancer cells and deliver the therapeutic dose is required. In this study, a folate-derivative of β-cyclodextrin has been studied as a vehicle for targeting folate receptors (FR) and delivering the chemotherapeutic drug methotrexate (MTX). FRs can be considered key cell membrane targets since they are commonly over-expressed in cancer cells and play an important role in cancer development and progression. Cyclodextrins (CDs) are cyclic oligosaccharides with a unique structure that allows them to form inclusion complexes with guest molecules, increasing their aqueous …

Infectious diseases remain one of the leading causes of morbidity and mortality worldwide. The WHO and CDC have expressed serious concern regarding the continued increase in the development of multidrug resistance among bacteria. Therefore, the antibiotic resistance crisis is one of the most pressing issues in global public health. Associated with the rise in antibiotic resistance is the lack of new antimicrobials. This has triggered initiatives worldwide to develop novel and more effective antimicrobial compounds as well as to develop novel delivery and targeting strategies. Bacteria have developed many ways by which they become resistant to antimicrobials. Among those are …
