Uveal melanoma (UM) is the most common primary intraocular malignancy in adults. The majority of the patients are Caucasian (97.8%) and aged 50-80 years. Choroidal melanoma is the predominant type (86.3%). The clinical presentation may range from no symptoms over various types of visual disturbances to visual loss. Examination includes slit-lamp biomicroscopy, indirect ophthalmoscopy and diagnostic testing, such as B-scan ultrasonography. A number of patients with posterior UM are treated with plaque radiation therapy or enucleation...

BACKGROUND: The number of people affected by Parkinson's disease (PD) is increasing in the United Kingdom driven by population ageing. The treatment of the disease is complex, resource intensive and currently there is no known cure to PD. The National Health Service (NHS), the public organisation delivering healthcare in the UK, is under financial pressures. There is a need to find innovative ways to improve the operational and financial performance of treating PD patients. The use of community services is a new and promising way of providing treatment and care to PD patients at reduced cost than hospital care...

Ankylosing spondylitis (AS) and axial spondyloarthritis (ax SpA) are chronic inflammatory diseases mainly involving the axial skeleton. Pharmacological treatments for AS and ax SpA usually include local glucocorticoid injections, NSAIDs and anti-TNFa agents. Since around 30% to 40% of patients are non responders or intolerant to anti-TNFa agents, we need new therapeutic options for AS and ax SpA. Areas covered: This review describes the new biological agents that can be used or are in development for AS or ax SpA as well as emerging synthetic targeted drugs...

Mitochondria are double-membrane-bound organelles involved mainly in supplying cellular energy, but also play roles in signaling, cell differentiation, and cell death. Mitochondria are implicated in carcinogenesis, and therefore dozens of lethal signal transduction pathways converge on these organelles. Accordingly, mitochondria provide an alternative target for cancer management. In this study, F16, a drug that targets mitochondria, and chlorambucil (CBL), which is indicated for the treatment of selected human neoplastic diseases, were covalently linked, resulting in the synthesis of a multi-mitochondrial anticancer agent, FCBL...

Von Hippel-Lindau (VHL)-associated hemangioblastomas (VHL-HB) arise in the central nervous system (CNS), and are a leading cause of morbidity and mortality in VHL disease. Currently, surgical resection is the most effective way to manage symptomatic VHL-HBs. Surgically unresectable VHL-HBs or those in frail patients are challenging problems. Therapies targeting oncologic and vascular endothelial growth factor (VEGF) pathways have failed to demonstrate tumor control. Our experience and previous reports on VHL-HB avidity to somatostatin analogues suggested somatostatin receptor (SSTR) expression in VHL-HBs, offering an alternative therapeutic strategy...

The association of pathogenic viruses with obesity has now been well-known in both human and animals. Globally, human obesity has become a serious problem leading to the emergence of multiple life-threatening diseases. Adenoviruses contribute a significant role in the induction of obesity by affecting various pathways. Due to impaired immunity, obese individuals are more prone to nosocomial infections leading to complications of obesity. In contrast, several other important factors contributing to human obesity are known...

INTRODUCTION: Successful outcomes in dental management for patients with inherited bleeding disorders require close collaboration between haematology teams and dentists. AIM: To review outcomes of an interdisciplinary pathway for dental procedures by assessing adequacy and appropriateness of haemostatic management. METHODS: Two hundred dental procedures in 30 patients with inherited bleeding disorders were included. A Dental Bleeding Risk Assessment and Treatment Tool (DeBRATT) was developed to identify four categories of bleeding risk (no risk, low, moderate and high risk of bleeding) in relation to the severity of the bleeding disorder and the invasiveness of dental procedure...

Gastroesophageal reflux disease (GERD) is a common disorder that has a well-established connection with obesity. To ameliorate the morbidity associated with obesity, bariatric procedures have become an established pathway to accomplish sustained weight loss. In some procedures, such as with the Roux-en-Y gastric bypass surgery, weight loss is also accompanied by the resolution of GERD symptoms. However, other popular bariatric surgeries, such as the sleeve gastrectomy, have a controversial impact on their effect on reflux...

Infectious diseases are transmitted when susceptible hosts are exposed to pathogen particles that can replicate within them. Among factors that limit transmission, the environment is particularly important for indirectly transmitted parasites. To try and assess a pathogens' ability to be transmitted through the environment and mitigate risk, we need to quantify its decay where transmission occurs in space such as the microclimate harbouring the pathogen. Hendra virus, a Henipavirus from Australian Pteropid bats, spills-over to horses and humans, causing high mortality...

BACKGROUND & AIMS: The severity of liver diseases is exacerbated by the death of hepatocytes, which can be induced by the sensing of Pathogen Associated Molecular Patterns (PAMPs) derived from the gut microbiota. The molecular mechanisms regulating these cell death pathways are poorly documented. In this study, we investigated the role of the Receptor Interacting Protein Kinase 1 (RIPK1), a protein known to regulate cell fate decisions, in the death of hepatocytes using two in vivo models of PAMP-induced hepatitis...

RNA interference has provided valuable insight into a wide range of biological systems and is a powerful tool for the analysis of gene function. The exploitation of this pathway to block the expression of specific gene targets holds considerable promise for the development of novel RNAi-based insect management strategies. In addition, there are a wide number of future potential applications of RNAi to control agricultural insect pests as well as its use for prevention of diseases in beneficial insects. The potential to synthesise large quantities of dsRNA by in-vitro transcription or in bacterial systems for RNA interference applications has generated significant demand for the development and application of high throughput analytical tools for the rapid extraction, purification and analysis of dsRNA...

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by periods of remission and periods of relapse. Patients often present with symptoms such as rectal bleeding, diarrhea and weight loss, and may require hospitalization and even colectomy. Long-term complications of UC include decreased quality of life and productivity and an increased risk of colorectal cancer. Mucosal healing (MH) has gained progressive importance in the management of UC patients. In this article, we review the endoscopic findings that define both mucosal injury and MH, and the strengths and limitations of the scoring systems currently available in clinical practice...

Insecticide resistance is a major obstacle to the management of disease-vectoring mosquitoes worldwide. The genetic changes and detoxification genes involved in insecticide resistance have been extensively studied in populations of insecticide-resistant, however few studies have focused on the resistance genes up-regulated upon insecticide exposure and the possible regulation pathways involved in insecticide resistance. To characterize the changes in gene expression during insecticide exposure, and to investigate the possible connection of known regulation pathways with insecticide resistance, we conducted RNA-Seq analysis of a highly-permethrin resistant strain of Culex quinquefasciatus following permethrin exposure...

Systemic lupus erythematosus (SLE) is a multi-organ disease of unknown etiology in which the normal immune responses are directed against the body's own healthy tissues. Patients with SLE often suffer from chronic pain. Currently, no animal studies have been reported about the mechanisms underlying pain in SLE. In this study, the development of chronic pain in MRL lupus-prone (MRL/lpr) mice, a well-established lupus mouse model, was characterized for the first time. We found that female MRL/lpr mice developed thermal hyperalgesia at the age of 13 weeks, and mechanical allodynia at the age of 16 weeks...

Adaptive immunity in intestinal inflammation may play a key role in the pathogenesis of Crohn's disease. In particular, interleukin (IL)-23 may be a key mediator in chronic intestinal inflammation by inducing the differentiation of naïve CD4+ T cells into Th17, with the production of several pro-inflammatory cytokines. Furthermore, IL-23 induces interferon-γ (IFN- γ) production from activated T cells, a critical cytokine in innate and adaptive immunity against infections. Areas covered: We aim to review the available data from literature regarding the role of IL-23, with a more specific focus on the recent progresses in the therapeutic modulation of this cytokine...

Protein aggregation is a hallmark of the major neurodegenerative diseases including Alzheimer's, Parkinson's, Huntington's and motor neuron and is a symptom of a breakdown in the management of proteome foldedness. Indeed, it is remarkable that under normal conditions cells can keep their proteome in a highly crowded and confined space without uncontrollable aggregation. Proteins pose a particular challenge relative to other classes of biomolecules because upon synthesis they must typically follow a complex folding pathway to reach their functional conformation (native state)...

In Parkinson's disease, motor signs have long been the main targets of the management of the disease. In recent years, non-motor disorders have elicited increasing interest. These disorders are under diagnosed and managed more difficultly than motor signs and are sometimes perceived as more disturbing by the patients. These signs are polymorphous, sometimes occurring before the motor symptoms but increase with the disease duration and complicating always the late stages. They may fluctuate as the motor signs, while being under the control of dopaminergic pathways, or be linked to the degeneration of other neuronal circuits...

Myeloproliferative neoplasms (MPNs) are clonal hematopoietic diseases that belong to the spectrum of myeloid malignancies (MyMs), which also include myelodysplastic syndromes (MDS), acute myeloid leukemia (AML), and chronic myelogenous leukemia (CML). While hematopoietic stem cell transplantation (HSCT) is a potentially curative therapeutic approach to many MyMs, the associated morbidity and mortality have necessitated the development of non-HSCT therapeutics for symptom management and disease course modification...
