A systematic literature review of the efficacy, effectiveness, and safety of filgrastim.

Purpose: Filgrastim (NEUPOGEN) is the originator recombinant human granulocyte colony-stimulating factor widely used for preventing neutropenia-related infections and mobilizing hematopoietic stem cells. This report presents findings of a systematic literature review and meta-analysis of efficacy and safety of originator filgrastim to update previous reports.

Methods: A literature search of electronic databases, congress abstracts, and bibliographies of recent reviews was conducted to identify English-language reports of clinical trials and observational studies evaluating filgrastim in its US-approved indications up to February 2015.

Multi-laboratory validation of a standard method for quantifying proanthocyanidins in cranberry powders.

Background: The objective of this study was to validate an improved 4-dimethylaminocinnamaldehyde (DMAC) colorimetric method using a commercially available standard (procyanidin A2), for the standard method for quantification of proanthocyanidins (PACs) in cranberry powders, in order to establish dosage guidelines for the uropathogenic bacterial anti-adhesion effect of cranberry.

Results: Commercially available cranberry samples were obtained (five from U.S.

Determination of total procyanidins in selected chocolate and confectionery products using DMAC.

A simple, specific, high-throughput colorimetric method based on the reaction of 4-dimethylaminocinnamaldehyde (DMAC) with flavan-3-ols was developed to determine total procyanidins in selected cacao-based products. Extracts of defatted samples were dispensed into a 96-well plate and reacted with DMAC. The absorbance of the reaction products was measured at 640 nm and compared to commercially available procyanidin B2 as a standard.

Novel high-throughput assay for antioxidant capacity against superoxide anion.

A novel high-throughput assay for measuring antioxidant capacity against superoxide anion has been developed and validated. In this assay, hydroethidine (HE), a fluorescent probe, is oxidized by superoxide anion generated by xanthine and xanthine oxidase and increases its fluorescence intensity. Therefore, the inhibition of loss of HE's fluorescence intensity in the presence of antioxidant is an index of antioxidant capacity.

Cyr61 is up-regulated in prostate cancer and associated with the p53 gene status.

Cysteine-rich 61 (Cyr61) is a member of the CCN protein family that has been implicated in diverse biological processes such as cell adhesion, proliferation, angiogenesis, and tumorigenesis. Altered expression of Cyr61 is found to be associated with human cancers. Here we show that Cyr61 was up-regulated in prostate cancer cell lines and tumor tissues.

Simultaneous proteomic profiling of four different growth states of human fibroblasts, using amine-reactive isobaric tagging reagents and tandem mass spectrometry.

In general, permanent growth arrest due to exhaustive cell replication can be induced prematurely by either stress or overexpression of selected oncogenes. In an attempt to examine key proteins involved in achieving premature senescence, and how they differ from those in serially passaged, replicatively exhausted cells, we used a novel proteomic profiling approach, isobaric tagging for relative and absolute quantitation (iTRAQ), to perform simultaneous four-way comparison of replicatively senescent fibroblasts, oxidatively stressed prematurely senescent fibroblasts, and their young replicating and quiescent counterparts. Two hundred and forty proteins were identified and quantified simultaneously; data analysis reveals: (1) groups of proteins whose expressions are uniformly either up- or down-regulated in all three growth arrest states; (2) signature proteins which may serve as candidate proteomic markers to differentiate the quiescent state from permanent growth arrest by either exhaustive replication or stress induction and (3) that while oxidative stress-induced, prematurely senescent fibroblasts morphologically resemble their replicatively exhausted counterparts, they exhibit different protein expression patterns.

Estimating cardiorespiratory fitness in well-functioning older adults: treadmill validation of the long distance corridor walk.

Objectives: To determine criterion validity of the 400-m walk component of the Long Distance Corridor Walk (LDCW) and develop equations for estimating peak oxygen consumption (VO2) from 400-m time and factors intrinsic to test performance (e.g., heart rate (HR) and systolic blood pressure (SBP) response) in older adults.

Self-referred whole-body CT imaging: current implications for health care consumers.

Purpose: To conduct an empirical analysis of self-referred whole-body computed tomography (CT) and develop a profile of the geographic and demographic distribution of centers, types of services and modalities, costs, and procedures for reporting results.

Materials And Methods: An analysis was conducted of Web sites for imaging centers accepting self-referred patients identified by two widely used Internet search engines with large indexes. These Web sites were analyzed for geographic location, type of screening center, services, costs, and procedures for managing imaging results.

Physiological and pathological implications of semicarbazide-sensitive amine oxidase.

Semicarbazide-sensitive amine oxidase (SSAO) catalyzes the deamination of primary amines. Such deamination has been shown capable of regulating glucose transport in adipose cells. It has been independently discovered that the primary structure of vascular adhesion protein-1 (VAP-1) is identical to SSAO.
