A growing body of evidence has suggested that microRNAs (miRNAs) play a pivotal role in the development and progression of pancreatic cancer. miRNA-449a (miR-449a) has attracted particular interest due to its critical role in regulating cancer biology in numerous cancer types. However, whether miR-449a is involved in the regulation of pancreatic cancer development and progression remains unknown. In this study, we aimed to investigate the expression pattern and potential biological function of miR-449a in pancreatic cancer...

OBJECTIVES: Sexual dysfunction (SD) has been shown to be more prevalent among females with epilepsy (FWE) when compared with controls. Identified risk factors for SD among FWE include depression, antiepileptic drug (AED) type, epileptic lateralization, and temporal lobe involvement. Despite a huge population of FWE in sub-Saharan Africa and by extension Nigeria, there are limited studies on the effect of AEDs and epilepsy on sexual function among FWE in the region. We therefore studied predictors and patterns of SD among Nigerian FWE...

BACKGROUND: Breast cancer has the highest incidence in women of all cancers and its burden is expected to continue to increase worldwide, especially in middle-income countries such as Thailand. The southern region of Thailand is unique in that it is comprised of 30% Muslims, whereas the rest of Thailand is 95% Buddhist. Breast cancer incidence and survival differ between these religious groups, but the association between clinical subtype of breast cancer and survival has not yet been assessed...

IL-21 is a much studied cytokine that has been implicated in the regulation of TH1, TH2, TH17 and regulatory immune responses; its signalling is a promising therapeutic target for autoimmune, inflammatory and infectious diseases. Despite its biological importance, measuring IL-21 reliably has proved difficult. ELISAs are commonly used to measure cytokines in various biological samples. However, results obtained are only as good as the quality of the sample. Here, we show that when using fresh samples, a significant increase in IL-21 was measured in the intestinal homogenate of mice infected with the intestinal worm Heligmosomoides polygyrus...

Major depressive disorder (MDD) is the most common psychiatric comorbidity in patients with obsessive-compulsive disorder (OCD). Hypothalamic-pituitary-adrenal (HPA) axis abnormalities have been described in both disorders and might play a role in the association between them. We aimed to study the role of HPA axis activity in the comorbidity between OCD and MDD, while controlling for psychopathological dimensions such as anxiety and depressive symptoms. We studied 324 participants belonging to four diagnostic groups: 1) MDD (n = 101), 2) OCD with comorbid MDD (n = 33), 3) OCD without MDD (n = 52), and 4) healthy subjects (n = 138)...

Alzheimer's disease (AD) is the most common cause of dementia, characterized by progressive cognitive decline. The main disease hallmarks include amyloid beta aggregates and neurofibrillary tangles. Brain pathology is reflected in cerebrospinal fluid (CSF); the core biomarkers amyloid beta 1-42, total and phosphorylated tau protein levels are changed, relative to cognitively normal elderly. Still, there is a need for additional biomarkers which could identify disease more accurately and at an earlier stage, predict severity and be used in research settings...

Toxoplasma gondii, an obligate intracellular protozoan, is the causative agent of toxoplasmosis, which can cause serious public health problems. The current drugs used to treat toxoplasmosis have many limitations. This study evaluated the anti-T. gondii activity and potential mechanism of Licochalcone A (Lico A) in vitro and in vivo. The safe concentration of Lico A in HFF cells was determined by MTT cell viability assays. The presence of T. gondii was assessed by qPCR and Giemsa staining. Azithromycin and sulfadiazine, commonly used effective treatments, served as drug controls...

Silver nanomaterials are widely used in clinically approved devices, consumer goods, and over-the-counter nutraceutical products. Despite the increase in silver nanomaterial research, few investigations have specifically distinguished the biological effects resulting from silver nanoparticles (AgNPs) versus silver ions released from AgNPs. This is in part, due to the complex analytical methods required to characterize silver ion release from AgNPs in biological media. This study sought to analyze silver ion release from AgNPs in biological media, compare silver transport from soluble AgNO3 and AgNPs through ex vivo full thickness sinus human tissue explants and human nasal epithelium and determine fractional AgNP internalization by human nasal epithelial cells...

The incidence of Barrett cancer is increasing rapidly and current screening protocols often miss the disease at an early, treatable stage. Volumetric Laser Endomicroscopy (VLE) is a promising new tool for finding this type of cancer early, capturing a full circumferential scan of Barrett's Esophagus (BE), up to 3-mm depth. However, the interpretation of these VLE scans can be complicated, due to the large amount of cross-sectional images and the subtle grayscale variations. Therefore, algorithms for automated analysis of VLE data can offer a valuable contribution to its overall interpretation...

Mitochondrial dysfunction and oxidative stress are very prominent and early features in Parkinson's disease (PD) and in animal models of PD. Thus, antioxidant therapy for PD has been proposed, but in clinical trials such strategies have met with very limited success. Methylene blue (MB), a small-molecule synthetic heterocyclic organic compound that acts as a renewable electron cycler in the mitochondrial electron transport chain, manifesting robust antioxidant and cell energetics-enhancing properties, has recently been shown to have significant beneficial effects in reducing nigrostriatal dopaminergic loss and motor impairment in acute toxin models of PD...

We evaluated test-retest reliability of sputum viscoelastic properties in clinically stable patients with cystic fibrosis (CF). Data from a prospective, randomized crossover study was used to determine within-subject variability of sputum viscoelasticity (G', storage modulus and G", loss modulus at 1 and 10 rad s-1 ) and solids content over three consecutive visits. Precision of sputum properties was quantified by with in-subject standard deviation (SDws ), coefficient of variation (CV) and intraclass correlation coefficients (ICC)...

AIMS: Studies on omega-3 fatty acids, including docosahexaenoic acid (DHA), reveal diverging results: Their intake is recommended in cardiovascular disease and major surgery, while evidence argues against use in septic patients. DHA mediates its blood-pressure-lowering effect through Slo1 channels that are expressed on cardiovascular and immune cells. We hypothesised that conflicting effects of immunonutrition could be explained by the influence of omega-3 fatty acids on systemic blood pressure or immune effector cells through Slo1...

The pharmacological stimulation of AMP-activated protein kinase (AMPK) via metabolic enhancers has been proposed as potential therapeutic strategy for Duchenne muscular dystrophy (DMD). Metformin, a widely-prescribed anti-hyperglycemic drug which activates AMPK via mitochondrial respiratory chain, has been recently tested in DMD patients in synergy with nitric oxide (NO)-precursors, with encouraging results. However, preclinical data supporting the use of metformin in DMD are still poor, and its actions on skeletal muscle appear controversial...
