Epitope of antiphospholipid antibodies retrieved from peptide microarray based on R39-R43 of β2-glycoprotein I.

Background: Antiphospholipid antibody (aPL) syndrome (APS) is an autoimmune disease characterized by the presence of antiphospholipid antibodies and thromboembolic or pregnancy complications. Although cryptic epitope R39-R43 belonging to beta-2-glycoprotein 1 (β2GP1) has been identified as the main antigenic determinant for aPLs, we have recently demonstrated that the epitope is a motif determined by the polarity, rather than by the sequence or charge of amino acids.

Objective: In the present study, we wanted to identify the association of residues needed to obtain the highest aPL affinity.

Tau proteins play a significant role in a variety of degenerative neurologic conditions. Postmortem neuropathology studies of victims of repeat and severe head trauma have defined a unique spatial expression of neurologic tauopathies in these individuals, known as chronic traumatic encephalopathy. Established and newly developed radiotracers are now being applied to head injury populations with the intent of diagnosis and disease monitoring.

Imaging Atherosclerosis by PET, With Emphasis on the Role of FDG and NaF as Potential Biomarkers for This Disorder.

Molecular imaging has emerged in the past few decades as a novel means to investigate atherosclerosis. From a pathophysiological perspective, atherosclerosis is characterized by microscopic inflammation and microcalcification that precede the characteristic plaque buildup in arterial walls detected by traditional assessment methods, including anatomic imaging modalities. These processes of inflammation and microcalcification are, therefore, prime targets for molecular detection of atherosclerotic disease burden.

Quantifying the cooling effect of rain events on outdoor thermal comfort in the southern coastal stations of the Caspian Sea.

Purpose: Positron emission tomography (PET) has been widely utilized in the study of traumatic brain injury (TBI) for decades. While most applications of PET have attempted to assess neuronal function after TBI, more recently, novel radiotracers have sought to image biomarkers in the context of TBI and chronic traumatic encephalopathy (CTE).

Methods: This review will begin with an overview of TBI and CTE along with the acute and chronic pathophysiological consequences of TBI.

Evolving Role of PET in Detecting and Characterizing Atherosclerosis.

Cardiovascular molecular imaging has focused on assessing myocardial perfusion and ventricular ejection fraction. These modalities target late downstream effects of the atherosclerotic disease process; this calls for a change of focus toward methods that can detect early arterial wall changes before macrocalcifications become visible on computed tomography angiography and provide a better understanding of the disease process. We summarize current knowledge on PET in atherosclerosis and highlight pertinent questions relating to the early detection of atherosclerosis.

Pre-treatment partial-volume-corrected TLG is the best predictor of overall survival in patients with relapsing/refractory non-hodgkin lymphoma following radioimmunotherapy.

The role of fluorodeoxyglucose-positron emission tomography (FDG-PET) has been well established in assessment of lymphoma, including non-Hodgkin lymphoma (NHL). The aim of this study was to compare changes and survival predictive values of various quantification parameters of FDG-PET/CT in patients with relapsing/refractory lymphoma before and after radioimmunotherapy (RIT). Data from 17 patients with relapsing/refractory NHL, treated with targeted RIT after chemotherapy/radiotherapy, were retrospectively collected.

The Role of PET in Evaluating Atherosclerosis: A Critical Review.

Atherosclerosis is a common age-related disorder and is the major cause of morbidity and mortality in the developed countries. Structural imaging techniques, such as CT and MRI, have been of limited value in early detection of atherosclerotic plaques, and therefore, there is a dire need for techniques that are highly sensitive and specific for this purpose. Over the past decade, PET imaging with FDG and NaF has been tested for detection and characterization of atherosclerotic plaques in the major coronary arteries.

F-NaF and F-FDG as molecular probes in the evaluation of atherosclerosis.

The early detection of atherosclerotic disease is vital to the effective prevention and management of life-threatening cardiovascular events such as myocardial infarctions and cerebrovascular accidents. Given the potential for positron emission tomography (PET) to visualize atherosclerosis earlier in the disease process than anatomic imaging modalities such as computed tomography (CT), this application of PET imaging has been the focus of intense scientific inquiry. Although F-FDG has historically been the most widely studied PET radiotracer in this domain, there is a growing body of evidence that F-NaF holds significant diagnostic and prognostic value as well.
