Hypertensive Disorders of Pregnancy: Overview and Current Recommendations.

Hypertensive disorders of pregnancy include chronic hypertension, gestational hypertension, preeclampsia-eclampsia, and chronic hypertension with superimposed preeclampsia. These disorders are an important cause of maternal and fetal morbidity and mortality. Although advances in effective treatments have been made, current research has yet to identify a biochemical or diagnostic imaging marker to reliably predict preeclampsia. Despite current guidelines that address diagnosis and management of hypertensive ...

Sensitivity and specificity of a lateral flow immunoassay (LFI) in serum samples for diagnosis of melioidosis.

Culture is the gold standard for the diagnosis of melioidosis, an infection caused by Burkholderia pseudomallei. Here we evaluate a lateral flow immunoassay (LFI) to detect B. pseudomallei capsular polysaccharide (CPS) in serum samples.

New Diagnostic Possibilities for Neonatal Sepsis.

Progress in neonatal care has decrease morbidity and mortality due to neonatal sepsis (NS). Although diagnosis of sepsis continues to rely on blood culture, this method is too slow and limited by false-negative results. There are numerous sepsis biomarkers that have been evaluated for the early diagnosis of NS, but, to date, there is no single ideal biomarker, though novel biomarkers are becoming more sophisticated and specific in their clinical applications. This review provides an overview of the current ...

Circulating APP, NCAM and Aβ serve as biomarkers for Alzheimer's disease.

Alzheimer's disease (AD) is the most common neurodegenerative disease and the early diagnosis and intervention are important for valid treatment of AD. However, there are few biomarkers for the diagnosis and monitoring of AD. In the present study, circulating APP, NCAM, Aβ40, and Aβ42 were measured in order to identify which marker or combination of markers could be useful, cost-effective and noninvasive biomarkers for diagnosing and continuously monitoring AD. The results showed that circulating APP, NCA...

LncRNA CCAT1 promotes the progression of preeclampsia by regulating CDK4.

Preeclampsia is one of the leading causes of maternal and perinatal deaths. This study mainly explored the mechanism of long non-coding RNA (lncRNA) CCAT1 expression in the placenta of preeclampsia patients and its effect on the progression of preeclampsia.

High sensitive and multiple detection of Acute Myocardial Infarction Biomarkers based on a dual-readout Immunochromatography Test Strip.

Immunochromatography test strip (ICTS) displayed high advantages in screening acute myocardial infarction (AMI) biomarkers. However, the low sensitivity and nonquantitative results seriously limited its clinical application. Herein, we designed a high sensitive, quantitative and dual-readout ICTS for assaying multiple AMI biomarkers based on magnetic nanoparticles (MNPs) quenching the fluorescence of Cy5, which was labeled on capture antibodies on test (T) lines. The changes of fluorescent intensity caused ...

Early-onset preeclampsia predisposes to preclinical diastolic left ventricular dysfunction in the fifth decade of life: An observational study.

Systemic inflammation, endothelial dysfunction and deficient vascularization of either uterus or myocardium are mechanistic hallmarks of early-onset preeclampsia and heart failure with preserved ejection fraction (HFpEF). HFpEF is especially prevalent in elderly women and preceded in middle age by preclinical left ventricular (LV) diastolic dysfunction. To detect if preeclampsia predisposes to HFpEF at later age, echocardiographic indices of LV function and of LV structure and biomarkers of systemic inflamm...

Celastrol attenuates symptoms of preeclampsia in rats by inhibiting matrix metalloproteinase-9.

Preeclampsia is reported in pregnant women around the world and often causes maternal/fetal mortality and morbidity. In the current study, we assessed the efficacy of celastrol on a rat preeclampsia model induced by N-nitro-L-arginine methyl ester hydrochloride (L-NAME). Pregnant rats were administered L-NAME to establish preeclampsia. A total of 48 animals were randomly assigned into 4 groups (n=12 each): control, control plus celastrol treatment (control+celastrol), preeclampsia, and preeclampsia plus cel...

Plasma and CSF biomarkers for the diagnosis of Alzheimer's disease in adults with Down syndrome: a cross-sectional study.

Diagnosis of Alzheimer's disease in Down syndrome is challenging because of the absence of validated diagnostic biomarkers. We investigated the diagnostic performance of plasma and CSF biomarkers in this population.

Sepsis and identification of reliable biomarkers for postoperative period prognosis.

Sepsis is currently defined as the presence of organ dysfunction occurring as the result of a disturbed host response to a serious infection. Sepsis is one of the most common diseases, which cause mortality and a considerable absorber of healthcare resources. Despite progress in technology and improving knowledge of pathophysiology, the disease mechanism is still poorly understood. At present, diagnosis is based on non-specific physiological criteria and on the late identification of the pathogen. For these...

Autofluorescence-free Immunoassay using X-ray Scintillating Nanotags.

Auto-fluorescence background in complex biological samples is a major challenge in achieving high sensitivity of fluorescence immunoassays (FIA). Here we report an X-ray luminescence-based immunoassay for high-sensitivity detection of biomarkers using X-ray scintillating nanotags. Due to the weak scattering and absorption of most biological chromophores by X-ray excitation, a low-dose X-ray source can be used to produce intense scintillating luminescence from the nanotags for autofluorescence-free biosensin...

A tag SNP in syncytin-2 3-UTR significantly correlates with the risk of severe preeclampsia.

Preeclampsia is a disease that frequently complicates pregnancy and poses a serious threat to maternal and fetal health. The causes and pathogenic mechanisms of preeclampsia are poorly defined. Genetic predisposition could be an important etiological factor. Previous studies have demonstrated that syncytin-1 and syncytin-2, encoded by the genes ERVWE1 and ERVFRDE-1, are involved in the pathogenesis of preeclampsia.

Hypermethylation of delta-like homolog 1/maternally expressed gene 3 loci in human umbilical veins: insights into offspring vascular dysfunction born after preeclampsia.

Increasing epidemiological studies have confirmed the association between maternal preeclampsia and elevated blood pressure in their offspring. Though case-control or cohort studies have demonstrated long-term outcomes for the offspring of preeclampsia, it is still a question that how these changes were caused by genetic reasons or by preeclampsia itself.

Development of Polyclonal Antibody against Clenbuterol for Immunoassay Application.

Development of an immunoassay for clenbuterol (CLB) detection required an anti-CLB antibody as an important bioreceptor. In this study, we report our work on production and purification of a rabbit-derived polyclonal anti-CLB antibody. The antibody was then purified by nProtein A Sepharose affinity column and the antibody purity was confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis. The activities of purified antibody were evaluated based on high antibody titer deter...

Statistical and artificial neural network-based analysis to understand complexity and heterogeneity in preeclampsia.

Preeclampsia is a pregnancy associated disease. It is characterized by high blood pressure and symptoms that are indicative of damage to other organ systems, most often involving the liver and kidneys. If left untreated, the condition could be fatal to mother and baby. This makes it important to delineate the complexities associated with the disease at a molecular level that would help develop methods for early diagnosis. In microarray-based studies, Textoris et al. and Mirzakhani et al. have analyzed the t...

Cerebrospinal fluid biomarkers measured by Elecsys assays compared to amyloid imaging.

Levels of amyloid β peptide 42 (Aβ42), total tau, and phosphorylated tau-181 are well-established cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease, but variability in manual plate-based assays has limited their use. We examined the relationship between CSF biomarkers, as measured by a novel automated immunoassay platform, and amyloid positron emission tomography.

Chronic hypertension in pregnancy: the impact of ethnicity and superimposed preeclampsia on placental, endothelial and renal biomarkers.

Black ethnicity is associated with worse pregnancy outcomes in women with chronic hypertension. Pre-existing endothelial and renal dysfunction, and poor placentation may contribute but pathophysiological mechanisms underpinning increased risk are poorly understood. This cohort study aimed to investigate the relationship between ethnicity, superimposed pre-eclampsia and longitudinal changes in markers of endothelial, renal and placental dysfunction in women with chronic hypertension. Plasma concentrations of...

Maternal allergy as an isolated risk factor for early-onset preeclampsia: An epidemiological study.

Immunological mechanisms underlying the development of preeclampsia are well known, but no association to allergy has yet been demonstrated. The aim of this study was to assess the correlation between maternal pre-gestational allergy, and early-onset and late-onset preeclampsia, respectively. It was a retrospective cohort study including all women giving birth in the Norwegian cities of Stavanger (1996-2014) and Bergen (2009-2014). Pre-gestational asthma, allergy, other known risk factors for preeclampsia, ...
