Investigation of Strength Properties for Concrete Containing Fine-Rubber Particles Using UPV.

Since the early 1990s, many studies were conducted to utilize waste tires as a replacement for natural coarse and fine aggregates in concrete, known as rubberized concrete or rubber-concrete. In this paper, an experimental study was performed on the strength properties of concrete containing fine-rubber particles as a replacement of fine aggregate, using destructive and non-destructive tests. Ultrasonic pulse velocity (UPV) tests were used to evaluate the strength property of rubber-concrete as a non-destructive test.

F-18 FDG PET/CT in NK/T-Cell Lymphoma that Progressed from Epstein-Barr Virus-Associated Hemophagocytic Lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) is a syndrome involving an uncontrolled immune response with variable triggers. HLH is rare but highly fatal, even with proper treatment; therefore, early recognition and diagnosis are crucial for management. Although the role of F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in HLH is poorly defined, it can provide valuable information on disease status and possible triggers.

Simulating dose reduction for myocardial perfusion SPECT using a Poisson resampling method.

Purpose: The purpose of this study was to determine the lowest Tl-201 dose that does not reduce the image quality of myocardial perfusion SPECT (MPS) by Poisson resampling simulation.

Methods: One hundred and twelve consecutive MPS data from patients with suspected or known coronary artery disease were collected retrospectively. Stress and rest MPS data were resampled using the Poisson method with 33%, 50%, 67%, and 100% count settings.

Hilar Choledochal Cyst Mimicking Biliary Atresia on Hepatobiliary Scintigraphy: a Case Report.

Hepatobiliary scintigraphy has been widely used for the differential diagnosis of neonatal cholestasis. Relatively good hepatic uptake with no evidence of excretion into the bowel for up to 24 h is a representative finding of biliary atresia. Hepatobiliary scintigraphy has very high sensitivity and moderate specificity.

Using the Chicken Chorioallantoic Membrane In Vivo Model to Study Gynecological and Urological Cancers.

Mouse models are the benchmark tests for in vivo cancer studies. However, cost, time, and ethical considerations have led to calls for alternative in vivo cancer models. The chicken chorioallantoic membrane (CAM) model provides an inexpensive, rapid alternative that permits direct visualization of tumor development and is suitable for in vivo imaging.

A Case of Radioactive Iodine Uptake Found in Artificial Eye.

Radioactive iodine (RAI) therapy is widely used as an adjunctive treatment in patients with differentiated thyroid cancer. Although I has high avidity in the functioning thyroid, and in differentiated thyroid cancer lesions, physiological and nonspecific uptake of I in healthy or benign tissue may contribute to false-positive findings on an I scan. Here, we present an interesting image of RAI uptake in the eye region post-RAI treatment, which has been identified as tear contamination in the artificial eye.

Anaplastic Oligodendroglioma Found as an Incidental Photopenic Lesion on 18F-FP-CIT PET/CT Image.

F-FP-CIT PET is a useful modality for imaging dopamine transporters. It has excellent resolution compared with I-beta-CIT SPECT and is widely used clinically for the evaluation of Parkinson disease. In general, the main focus of F-FP-CIT PET imaging is the basal ganglia, and it is important to observe whether F-FP-CIT uptake is normal in the putamen and caudate nuclei.

Extracting information from free-text electronic patient records to identify practice-based evidence of the performance of coronary stents.

Background And Objective: Percutaneous coronary intervention (PCI) using drug-eluting stents (DES) is an indispensable treatment for coronary artery disease. However, to evaluate the performance of various types of stents for PCI, numerous resources are required. We extracted clinical information from free-text records and, using practice-based evidence, compared the efficacy of various DES.

Synephrine inhibits eotaxin-1 expression via the STAT6 signaling pathway.

Citrus contain various flavonoids and alkaloids that have multiple biological activities. It is known that the immature Citrus contains larger amounts of bioactive components, than do the mature plants. Although Citrus flavonoids are well known for their biological activities, Citrus alkaloids have not previously been assessed.

An alternative to Western blot analysis using RNA aptamer-functionalized quantum dots.

To make full use both of optical properties of quantum dots (QDs) and of specific interactions between aptamers and their ligands of interest, we employed QD-conjugated RNA aptamer interactions with histidine tag. QDs offer revolutionary fluorescence performance due to their long-term photostability, brilliant colors, fixability, and narrow, symmetrical emission spectra, and aptamers are known to specifically bind to their target molecules, including metal ions, small molecules, and macromolecules. In this study, we have synthesized RNA aptamer-functionalized QDs, and demonstrated their application to specific protein detection, as an alternative to the conventional Western blot analysis.
