REVIEW
Ryan Patel, Carlota Montagut-Bordas, Anthony H Dickenson
Neuropathic pain remains poorly treated for large numbers of patients and little progress has been made in developing novel classes of analgesics. To redress this issue, ziconotide (Prialt(TM) ) was developed and approved as a first in class synthetic version of ω-conotoxin MVIIA, a Cav 2.2 peptide blocker. Unfortunately, the impracticalities of intrathecal delivery, low therapeutic index and severe neurological side effects associated with ziconotide has restricted its use to exceptional circumstances. Ziconotide exhibits no state or use dependent block of Cav 2...

The purpose of the present study is to explore the effects of a lipid-lowering drug atorvastatin, a three-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor, in the treatment of erectile dysfunction (ED) in a rat model of atherosclerosis (AS) and the possible mechanisms underneath. A high-cholesterol diet was administrated to Sprague-Dawley rats in an attempt to induce an ASED model, which was later confirmed by abdominal aorta histopathology and erectile function evaluation. ASED rats were further assigned to non-treatment group, atorvastatin low-dose treatment group (5 mg kg(-1)  day(-1) ), high-dose group (10 mg kg(-1)  day(-1) ) and sildenafil (1...

Overactive bladder is a common symptom complex with health related quality of life impacts on the individual as well as utilising health resources. Antimuscarinic therapy has been the mainstay of treatment and is well supported within the literature and guidelines. However, compliance is poor due to lack of efficacy and adverse events leading to the development of novel therapies. Mirabegron, the B3-adrenoreceptor agonist has emerged as an evidence-based alternative first or second line therapy. Two decades after its first clinical application for overactive bladder, intravesical botulinum toxin is now an important part of any clinician's armamentarium for refractory cases...

Nano eye-drops are a new type of ophthalmic treatment with increased potency and reduced side effects. Compounds in conventional eye-drops barely penetrate into the eye because the cornea, located at the surface of eye, has a strong barrier function for preventing invasion of hydrophilic or large-sized materials from the outside. In this work, we describe the utility of nano eye-drops utilising brinzolamide, a commercially available glaucoma treatment drug, as a target compound. Fabrication of the nanoparticles of brinzolamide prodrug increases the eye penetration rate and results in high drug efficacy, compared with that of commercially available brinzolamide eye-drops formulated as micro-sized structures...

BACKGROUND: Health insurance funds in Germany are obliged to offer family doctor-centred health care models (Hausarztzentrierte Versorgung, "HzV"). The participation is voluntary for the insured persons. Participants agree to utilise outpatient specialist care only if their family doctor or general practitioner ("gatekeeper") refers them to a specialist. The aim of this programme is to both strengthen the role of general practitioners and to avoid unnecessary specialist visits and double examinations...

REVIEW
Duncan Ayers, Jo Vandesompele
Innate and acquired chemoresistance exhibited by most tumours exposed to conventional chemotherapeutic agents account for the majority of relapse cases in cancer patients. Such chemoresistance phenotypes are of a multi-factorial nature from multiple key molecular players. The discovery of the RNA interference pathway in 1998 and the widespread gene regulatory influences exerted by microRNAs (miRNAs) and other non-coding RNAs have certainly expanded the level of intricacy present for the development of any single physiological phenotype, including cancer chemoresistance...

There are several new treatment options for patients whose asthma remains uncontrolled on free-dose and fixed-dose combinations of inhaled corticosteroids plus long-acting β2-agonists (ICS+LABA). In order to evaluate the likely impact of these treatments, we assessed the effect of uncontrolled asthma on healthcare and patient burden within the UK among adult patients treated with ICS+LABA. Data obtained from 2010-2011 UK National Health and Wellness Surveys identified 701 patients treated with ICS+LABA. Patients with not well-controlled asthma (Asthma Control Test™ score <20) were compared with well-controlled asthma (score ≥ 20) patients on multiple measures...

Ruxolitinib is a dual janus kinase 1 (JAK1)/JAK2 inhibitor used to treat splenomegaly and symptoms associated with myelofibrosis (MF). Current therapeutic options for symptomatic MF include supportive care, myelosuppressive therapy (such as hydroxycarbamide) and janus kinase (JAK) inhibitors (in particular ruxolitinib). Allogeneic stem cell transplantation remains the only potentially curative treatment for MF, and younger transplant-eligible patients should still be considered for allogeneic stem cell transplantation; however, this is applicable only to a small proportion of patients...

BACKGROUND: Topical photodynamic therapy (PDT) is a non-invasive light based therapy used to treat non-melanoma skin cancer (NMSC) and dysplasia. During PDT, the light sensitive molecule protoporphyrin IX (PpIX) is activated, resulting in the production of singlet oxygen, which subsequently leads to cell death. PpIX is metabolised from a topically applied pro-drug and the strong fluorescence signal associated with PpIX can be utilised as an indicator of the amount of PpIX present within the tumour tissue...

AIM: Liver-enriched microRNA-122 (miR-122) is a novel circulating biomarker for drug-induced liver injury (DILI). To date, miR-122 has been measured in serum or plasma venous samples. If miR-122 could be measured in capillary blood obtained from a finger prick it would facilitate point-of-care testing, such as in resource-limited settings that have a high burden of DILI. METHODS: In this study, in healthy subjects, miR-122 was measured by PCR in 3 capillary blood drops taken from different fingers and in venous blood and plasma (N = 20)...

Innovative methods and materials have been developed to overcome limitations associated with current drug delivery systems. Significant developments have led to the use of a variety of materials (as excipients) such as inorganic and metallic structures, marking a transition from conventional polymers. Inorganic materials, especially those possessing significant porosity, are emerging as good candidates for the delivery of a range of drugs (antibiotics, anticancer and anti-inflammatories), providing several advantages in formulation and engineering (encapsulation of drug in amorphous form, controlled delivery and improved targeting)...
