Functional Magnetic Resonance Imaging (fMRI) is at present one of the most used methodologies for functional brain exploration, both in clinical and research settings. fMRI can noninvasively measure neural activity by using specific experimental paradigms. Often, these paradigms require the stimulation of the subject to perform sensorimotor tasks: in the past, the stimuli have been administered manually for investigating fundamental aspects of tactile perception and somatosensory processing. Nowadays, the use of mechatronic devices to stimulate the subject during fMRI studies is growing, also to assure reproducibility, control, and monitoring of task performances...

Heartburn is the most specific symptom of gastroesophageal reflux disease (GERD). In clinical practice, heartburn relief by a proton pump inhibitor (PPI) trial does suffice to confirm GERD. However, an objective diagnosis of GERD is required before anti-reflux endoscopic or surgical interventions, independently from PPI response. Thus, since normal findings at upper endoscopy are detected in the majority of patients with heartburn, reflux monitoring is often required. When traditional catheter-based or wireless pH tests are used, reflux episodes are conventionally identified by pH drops below 4...

Mild cognitive impairment (MCI) is common in patients with Parkinson's disease (PD) and should be recognized early because it represents a predictor of PD-related dementia and worse disease course. Diagnostic criteria for PD-related MCI (PD-MCI) have recently been defined by a Movement Disorders Society (MDS) task force. The present study explored which neuropsychological tests perform best for a level II (i.e., comprehensive neuropsychological assessment) diagnosis of PD-MCI according to the MDS task force criteria in Italian-speaking PD patients...

Antiphospholipid antibody syndrome is an autoimmune disease characterized by the presence of so-called antiphospholipid antibodies and clinical manifestations such as recurrent thromboembolic or pregnancy complications. Although the main antigenic determinant for antiphospholipid antibodies has been identified as the beta-2-glycoprotein 1 (β2GP1), the precise epitope recognized by antiphospholipid antibodies still remains largely unknown. In the present study, we wanted to identify a sequence in the domain I of β2GP1 able to induce the proliferation of CD4+ T cells isolated from antiphospholipid antibody syndrome patients but not from healthy donors and to interact with antiphospholipid antibodies...

BACKGROUND: Articular infection is an orthopedic challenge due to its difficult diagnosis and devastating results. Various diagnostic studies exist: culture, ESR, CRP, count of leukocytes, among others, but none is specific, they all take more than 30 minutes to complete, and require complex infrastructure. In this study, we determine the sensitivity and specificity of the leukocyte esterase for detection of an infectious process joint in Mexican population. MATERIAL AND METHODS: During November 2015 to April 2016, we obtained synovial fluid from two groups of patients: one with a diagnosis of synovial joint infection with or without implant, and the control group, without infection but with degenerative pathology of the knee...

Cyprinid herpesvirus 2 (CyHV-2) is the main pathogen responsible for causing haematopoietic necrosis disease in Carassius auratus gibelio. Although many nucleic acid-based diagnostic methods have been applied, no stable and sensitive immunological diagnostic approaches have been reported. In this study, to detect CyHV-2 in clinical samples using immunological methods, recombinant ORF72 protein (pORF72), encoded by the CyHV-2 ORF72 gene, was used as a capture antigen to identify blood and tissues infected with CyHV-2...

Background: Hepatocellular carcinoma (HCC) is a common malignancy that occurs secondary to viral hepatitis B and C cirrhosis under the influence of environmental factors. In early stages, clinical diagnosis is often difficult and distinguishing HCC from cirrhosis and other hepatic masses by conventional tests is frequently not feasible. Physicians usually depend on measuring serum alpha-fetoprotein (AFP), but this marker has low sensitivity and specificity. The aim of this research was to determine any role of serum cytokeratin-18(Ck-18) as a marker for diagnosis of HCC in patients with liver cirrhosis...

BACKGROUND: Long bone posttraumatic osteomyelitis (PTOM) is a relatively common complication following surgical fixation of open fractures. There is a lacking consensus on ideal strategies for diagnostic evaluation of long bone PTOM. While open bone biopsy and culture is considered the 'gold diagnostic standard,' its cost and invasiveness are often prohibitive and have prompted the search for alternate diagnostic methods. OBJECTIVE: To evaluate the sensitivity and specificity of various diagnostic modalities relative to open bone biopsy and culture for the detection of long bone PTOM...
