self-reported measures of dietary intake are prone to measurement error that may obscure the relationship of diet and disease. this review addresses strategies to decrease errors during collection of dietary data and statistical approaches to deal with measurement issues once the data are collected. examples from two us studies-- the women’s health initiative (whi) dietary modification trial a...
The Area under the ROC Curve (AUC) is a common index for evaluating the ability of the biomarkers for classification. In practice, a single biomarker has limited classification ability, so to improve the classification performance, we are interested in combining biomarkers linearly and nonlinearly. In this study, while introducing various types of loss functions, the Ramp AUC method and some of...

Alzheimer’s disease (AD) is the most popular type of dementia in elderly and is described by a progressive loss of cognitive capacity and severe neurodegeneration which typically begins with memory deficits. The major biomarkers of AD include total tau, phosphorylated-tau and 42 amino acid isoform of amyloid beta that reflect neurodegeneration and indicate the pathophysiological processes in AD...
background: given the high prevalence of type ii diabetes and its complications, the evidence regarding the beneficial effects of probiotic yogurt on some cardiovascular biomarkers in diabetic patients is worthy of investigation. aim: to investigate the effect of probiotic yogurt on blood glucose level and cardiovascular biomarkers in patients with type ii diabetes. method:this randomized, clin...
objective(s): nanosilver is one of the most widely used nanomaterials due to its strong antimicrobial activity. thus, because of increasing potential for exposure of human to nanosilver, there is an increasing concern about possible side effects of these nanoparticles. in this study, we tested the potential dermal toxicity of nanosilver bandage on serum chemical biomarkers in mice. materials a...
perhaps, due to the impact of post-traumatic stress disorder (ptsd) on biological markers of cardiovascular such as systolic and diastolic blood pressure, heart rate, body temperature, physiological response to reminders of trauma has become an essential part and hallmark of the diagnostic and statistical manual of mental disorders (fifth edition-dsm-5, american psychiatric association, 2013). ...
objective: heparin and enoxaparin possess anti-inflammatory properties. we compared the effects of these drugs on inflammatory biomarkers in patients with st-segment elevated myocardial infarction (stemi). method: thirty four patients with stemi randomly separated in two groups and received standard doses of heparin and enoxaparin. the serum concentration of serum amyloid a (saa), c-reactive pr...
conclusions changes in s100b protein, especially the levels of this dimer 48 hours after trauma can be used as marker to predict brain death. alongside other known prognostic factors such as age, gcs and diameters of the pupils, however, this factor individually can not conclusive predict the patient's clinical course and incidence of brain death. however, it is suitable to use gcs, ct scan, cl...
Bladder cancer is among the ten most common cancers and the ten main causes of cancer-related deaths in the world. Currently, bladder tumors are diagnosed and followed up using a combination of cystoscopy and cytology. In addition, bladder cancer often recurs and can progress if not closely monitored after initial treatment. Constant monitoring of the patient with cystoscopy, which is an invasi...
