Bladder cancer is one of the most common cancers worldwide, with a high rate of recurrence and poor outcomes as a result of relapse. Bladder cancer patients require lifelong invasive monitoring and treatment, making bladder cancer one of the most expensive malignancies. Lines of evidence increasingly point to distinct genetic and epigenetic alteration patterns in bladder cancer, even between the different stages and grades of disease. In addition, genetic and epigenetic alterations have been demonstrated to play important roles during bladder tumorigenesis...

REVIEW
Jia-Fong Jhang, Hann-Chorng Kuo
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a heterogeneous syndrome which is usually characterized by urinary frequency, nocturia, and bladder pain. Several pathomechanisms have been proposed, including uroepithelial dysfunction, mast cell activation, neurogenic inflammation, autoimmunity, and occult urinary tract infections. It is possible that an inflammatory process alters regulation of urothelial homeostasis and results in dysfunction of the bladder epithelium. Different phenotypes of IC/BPS have been explored including Hunner and non-Hunner type IC, hypersensitive bladder, and bladder pain both with and without functional somatic syndrome...

BACKGROUND: White globe appearance (WGA) refers to a small white lesion of globular shape underneath cancerous gastric epithelium that can be clearly visualized by magnifying endoscopy with narrowband imaging (M-NBI). WGA has been reported to be a novel endoscopic marker that is highly specific in differentiating early gastric cancer (GC) from low-grade adenoma, and has a significantly higher prevalence in early GCs than in noncancerous lesions. However, interobserver agreement in detecting WGA and whether training intervention can improve diagnostic accuracy are unknown...

A 59-year-old woman with a painful right knee that became locked in extension after a trivial trauma was seen at the emergency room. This was caused by unloaded hyperextension in bed. She was diagnosed with a superior dislocation of the patella. A closed reduction was performed, but a recurrent episode was seen within a week. An arthroscopy was performed, in which the causative osteophytes were removed. In the 12-month follow-up after treatment, no recurrence was seen. A superior dislocation of the patella is caused by patellofemoral osteophytes that interlock...

Mastitis is positioned as the most vital ailment in dairy cows in light of conventional cost examinations. The aim of the present study was to evaluate the diagnostic value of different acute phase proteins (APPs), pro-inflammatory cytokines, and oxidative stress biomarkers in healthy cows and in those with clinical or subclinical mastitis and to localize APP gene expression in the milk of mastitic cows. Therefore, 20 subclinical mastitic cows with positive California Mastitis Test (CMT) results and no clinical signs of mastitis, 15 clinically mastitic cows, and 15 healthy cows with negative CMT results and somatic cell count (SCC) of <600,000 cells/mL were selected...

Intracranial tuberculoma is an uncommon presentation of tuberculosis, and its occurrence in an intraventricular location is very rare. It is usually confused with glioma, parasitic cyst, and craniopharyngioma. Few case reports exist in the literature on this entity. We report a case of tuberculoma at the foramen of Monro in a 7-year-old child and review the literature in terms of diagnostic dilemma.

The incidence of invasive fungal disease (IFD) has varied during the last decades. However, over the years, we have observed a progressive reduction of mortality, mainly due to wider use of prophylactic antifungal therapy (i.e., new azoles, such as posaconazole), the development of new and more effective antifungal drugs (lipid compounds of amphotericin B, candins, and azoles of the previous generation) and improvement of diagnostic tools. Based on a number of international studies across three decades, the attributable mortality rate for IFD and invasive aspergillosis (IA) among patients with acute myeloid leukemia (AML) has progressively declined...

Galactomannan (GM) assay is commonly used as an early diagnostic tool for invasive fungal infection (IFI) in high-risk hematology patients. False positivity is frequently observed in GM with the use of piperacillin/tazobactam. The usage of generic drugs over the original brand has a significant cost advantage. The aim of this study was to assess the performance of GM test among patients receiving original and generic piperacillin/tazobactam formulations. The study included 85 adult patients; 62.4% were male with hematological malignancy currently receiving piperacillin/tazobactam...

Rolling circle amplification (RCA) is an isothermal amplification technique with high efficiency and perfect accuracy for nucleic acids detection. However, RCA technique suffers the limitation to detect short DNA or RNA molecules. For long nucleic acid molecules, enzymatic restriction as well as heat denaturation process is usually required, which makes the amplification not effective and strictly isothermal. In this article, a simple and efficient one-pot self-primed isothermal amplification (SIA) was developed for detection of genomic DNA directly based on the combination of nicking endonuclease assisted strand displacement amplification (SDA) and exponential RCA...

PURPOSE: There have been an increasing number of studies involving ultra-high-field 7T of intracranial pathology, however, comprehensive clinical studies of neuropathology at 7T still remain limited. 7T has the advantage of a higher signal-to-noise ratio and a higher contrast-to-noise ratio, compared to current low field clinical MR scanners. We hypothesized 7T applied clinically, may improve detection and characterization of intracranial pathology. MATERIALS AND METHODS: We performed an IRB-approved 7T prospective study of patients with neurological disease who previously had lower field 3T and 1...

OBJECTIVE: Preserving the facial nerve (FN) during surgery for large vestibular schwannomas (VSs) is challenging because of the unpredictable locations and morphological changes in the FN. Diffusion tensor imaging-based fiber tracking (DTI-FT) has been proposed to preoperatively visualize the FN. This study was performed to evaluate the efficacy of DTI-FT for predicting FN location and shape in patients with large VSs. METHODS: In this prospective study, imaging data from 30 consecutive patients with large VSs were obtained using 3-T magnetic resonance imaging...

Rose rosette disease caused by Rose rosette virus (RRV; genus Emaravirus) is the most economically relevant disease of Knock Out(®) series roses in the U.S. As there are no effective chemical control options for the disease, the most critical disease management strategies include the use of virus free clean plants for propagation and early detection and destruction of infected plants. The current diagnostic techniques for RRV including end-point reverse transcription-polymerase chain reaction (RT-PCR) and real-time PCR (RT-qPCR) are highly sensitive, but limited to diagnostic labs with the equipment and expertise; and is time consuming...

BACKGROUND: Soluble urokinase-type plasminogen activator receptor (suPAR) is a glycoprotein secreted during inflammation and infections. Moreover, increased levels of suPAR are observed after hypoxia and ischaemia. The aim of the study was to assess whether suPAR could represent a useful marker of acute pancreatitis (AP) severity. PATIENTS AND METHODS: We have observed a cohort of 126 prospectively enrolled patients. Based on the presence of persistent organ failure (more than 48 h) and local complications (diagnosis of moderate AP [MSAP]), patients were classified into three groups: mild AP (MAP), moderate and severe AP (SAP)...

Ezrin and Annexin seven (A7) have been suggested to be involved in several roles in cancers metastasis. However, the role of Ezrin and the effect of A7 on Ezrin expression in lymphatic metastatic hepatocellular carcinoma (LNM-HCC) have not been extensively explored yet. This study reports expression of Ezrin in high lymphatic metastasis (Hca-F >70%) and low metastatic metastasis (Hca-P <30%) HCC cell lines, and the effect of A7 on Ezrin expression. Real-Time PCR, Western blot, Subcellular fractionation, Immunocytochemistry and Immunofluorescence were used to investigate Ezrin expression in addition to migration and invasion behaviors of A7 up-regulated Hca-F cells, A7 down-regulated Hca-P and in their respective negative control (NC) cells...

Nutrition is a major environmental influence on human health. Epidemiological and interventional studies suggest a pathophysiological or therapeutic role, respectively, for nutrition in inflammatory rheumatic diseases (IRDs). Nevertheless, the associations between nutrition and IRDs are often weak and inconsistent, and the available clinical trials on nutrition are methodologically flawed. Experimental evidence is accumulating that micronutrients in the diet may influence intestinal and systemic immune responses via complex interactions involving the gut microbiota...
