Levitt's CO breath test in the differential diagnosis of chronic isolated hyperbilirubinemia.

A key component of the differential diagnosis of isolated hyperbilirubinemia (HB) is distinguishing between hemolytic and non-hemolytic types. Routine hemolysis screening markers have unsatisfactory sensitivity and specificity. Erythrocyte (RBC) lifespan shortening, the gold standard marker of hemolysis, is seldomly measured due to the cumbersome and protracted nature of standard methods.

Red Blood Cell Lifespan Shortening in Patients with Early-Stage Chronic Kidney Disease.

Background: Although reduced red blood cell (RBC) lifespan has been reported to be a contributory factor to anemia in patients with end-stage chronic kidney disease (CKD), there are limited data regarding RBC lifespan in early-stage CKD. Serum erythropoietin (EPO) is considered a primary causative factor of renal anemia. The aims of this study were to compare the RBC lifespan, serum EPO levels, and other renal anemia indicators across CKD-stage groups of patients and to analyze the impacts of etiological factors on renal anemia.

[Validation and Evaluation of Diagnostic Efficiency of Genes Associated with Colorectal Cancer with Hyperglycemia].

Objective To verify the expressions of genes associated with colorectal cancer with hyperglycemia and evaluate their diagnostic values.Methods Tumor tissues,distal normal intestinal mucosa,and peripheral blood samples were harvested from 109 colorectal cancer patients and peripheral blood samples from 30 diabetes patients and 30 healthy volunteers. The mRNA expressions of glucose regulated protein 78 (GRP78),NADPH oxidase-1 (NOX1),carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5),heat shock protein 60 (HSP60),and histone deacetylase 1(HDAC1) were detected by real-time quantitative polymerase chain reaction.

Rapid CO breath test screening of drugs for protective effects on ribavirin-induced hemolysis in a rabbit model: a pilot study.

Hemolytic anemia is a major side effect of ribavirin antiviral treatment for chronic hepatitis C. Ribavirin dose reduction may compromise the antiviral response and erythropoietin can take several weeks to alleviate anemia. The purpose of the present study was to screen potentially protective drugs against ribavirin-induced hemolytic anemia in a rabbit model, using our modified CO breath test for measuring erythrocyte (RBC) lifespan, the gold standard diagnostic index of hemolysis.

A Modified Carbon Monoxide Breath Test for Measuring Erythrocyte Lifespan in Small Animals.

This study was to develop a CO breath test for RBC lifespan estimation of small animals. The ribavirin induced hemolysis rabbit models were placed individually in a closed rebreath cage and air samples were collected for measurement of CO concentration. RBC lifespan was calculated from accumulated CO, blood volume, and hemoglobin concentration data.

Marine natural products sourced from marine-derived Penicillium fungi.

Marine micro-organisms have been proven to be a major source of marine natural products (MNPs) in recent years, in which filamentous fungi are a vital source of bioactive natural products for their large metagenomes and more complex genetic backgrounds. This review highlights the 390 new MNPs from marine-derived Penicillium fungi during 1991 to 2014. These new MNPs are categorized based on the environment sources of the fungal hosts and their bioactivities are summarized.

High Blood Glucose Levels Correlate with Tumor Malignancy in Colorectal Cancer Patients.

BACKGROUND Research shows that type 2 diabetes mellitus (T2DM) affects the risk and prognosis of colorectal cancer (CRC). Here, we conducted a retrospective study to investigate whether the clinicopathological features of CRC patients correlate with their blood glucose levels. MATERIAL AND METHODS We enrolled 391 CRC patients hospitalized in our center between 2008 and 2013.

[Effects of coated controlled release urea combined with conventional urea on winter wheat growth and soil NO3- -N].

Field experiments were conducted to study the effects of different dosages coated controlled release urea (PCU60, 60 d release duration) combined with conventional urea (U) used as basal on the winter wheat grain yield, nitrogen (N) recovery rate, and soil NO3- -N content, etc. Five treatments were installed, i.e.

[Research and realization for certification of EHR based on ECC & SHA-1].

Using elliptic curve cryptosystem (ECC) and SHA-1 message digest algorithms to get the Electronic Health Record (EHR)'s digital finger print, then sending the digital finger print to another unattached organization through the internet, no information about the finger print will be stored on the local server. The system is designed to be a middleware and you can check out whether the EHR has been modified or not by using the finger print generated by the middleware, so as to ensure the EHR's originality and authenticity effectively.
