BACKGROUND: Alterations in protein glycosylation have been related to malignant transformation and tumour progression. We recently showed that low mRNA levels of Golgi alpha-mannosidase MAN1A1 correlate with poor prognosis in breast cancer patients. METHODS: We analysed the role of MAN1A1 on a protein level using western blot analysis (n=105) and studied the impact of MAN1A1-related glycosylation on the prognostic relevance of adhesion molecules involved in breast cancer using microarray data (n=194)...

There is a significantly higher risk for type II diabetes in HIV-1 carriers, albeit the molecular mechanism for this HIV-related pathology remains enigmatic. The 52 amino acid HIV-1 p6 Gag protein is synthesized as the C-terminal part of the Gag polyprotein Pr55. In this context, p6 promotes virus release by its two late (L-) domains, and facilitates the incorporation of the viral accessory protein Vpr. However, the function of p6 in its mature form, after proteolytic release from Gag, has not been investigated yet...

INTRODUCTION: PMMA-augmentation of pedicle screws strengthens the bone-screw-interface reducing cut-out risk. Injection of fluid cement bears a higher risk of extravasation, with difficulty of application because of inconsistent viscosity and limited injection time. OBJECTIVE: To test a new method of cement augmentation of pedicle screws using radiofrequency-activated PMMA, which is suspected to be easier to apply and have less extravasations. METHODS: Twenty-seven fresh-frozen human cadaver lumbar spines were divided into 18 osteoporotic (BMD ≤ 0...

BACKGROUND: Chemotherapy medications place nurses at risk for occupational exposure, a primary nursing safety concern. No literature was available on adherence to following chemotherapy handling practices and nurses' perceptions of safe-handling practices. OBJECTIVES: The aims of the pilot study were to examine actual and subjective ambulatory oncology nurse adherence to chemotherapy safe-handling guideline recommendations that prevent chemotherapy exposure. METHODS: A prospective, comparative mixed-methods study was used to compare objective and subjective nurse behaviors of expected safe chemotherapy handling-specifically, micro-ethnography and questionnaires...

Providing optimal pain care for patients is essential to the work of nursing and a measure of patient satisfaction prompting some hospitals to offer pain management classes for clinicians. Although nurses generally do well on knowledge tests after attending a pain class, actual improvement in pain care for patients may not occur. The personal values of the clinician may be a key driver of pain-management decision making. Therefore, a segment on how clinicians' personal values influence pain care decisions was added to a large Midwestern hospital's pain management class...

BACKGROUND: A seven-item cancer-specific fall risk tool (Cleveland Clinic Capone-Albert [CC-CA] Fall Risk Score) was shown to have a strong concordance index for predicting falls; however, validation of the model is needed. OBJECTIVES: The aims of this study were to validate that the CC-CA Fall Risk Score, made up of six factors, predicts falls in patients with cancer and to determine if the CC-CA Fall Risk Score performs better than the Morse Fall Tool. METHODS: Using a prospective, comparative methodology, data were collected from electronic health records of patients hospitalized for cancer care in four hospitals...

Structural characterization of large multi-subunit protein complexes often requires integrating various experimental techniques. Cross-linking mass spectrometry (XL-MS) identifies proximal protein residues and thus is increasingly used to map protein interactions and determine the relative orientation of subunits within the structure of protein complexes. To fully adapt XL-MS as a structure characterization technique, we developed Xlink Analyzer, a software tool for visualization and analysis of XL-MS data in the context of the three-dimensional structures...

A possible solution for the oversupply of dredged sediments is their use as a raw material in brick production. Despite the fact that several examples (e.g., Agostini et al., 2007; Hamer and Karius, 2002; Xu et al., 2014) show that this application is feasible, some economic, technical and social limitations interfere with the development of a market of dredged materials in brick production in Flanders. While we describe the main characteristics of the supply side, we focus on the limitations and barriers from the demand side in the present study...

Glutathione S-transferases (GSTs) are phase II drug detoxifying enzymes that play an essential role in the maintenance of cell integrity and protection against DNA damage by catalyzing the conjugation of glutathione to a wide variety of exo- and endogenous electrophilic substrates. Glutathione S-transferase P1 (GSTP1), the gene encoding the pi-class GST, is frequently inactivated by acquired somatic CpG island promoter hypermethylation in multiple cancer subtypes including prostate, breast, liver, and blood cancers...

Increased proliferation rates as well as resistance to apoptosis are considered major obstacles for the treatment of patients with chronic myelogenous leukemia (CML), thus highlighting the need for novel therapeutic approaches. Since senescence has been recognized as a physiological barrier against tumorigenesis, senescence-based therapy could represent a new strategy against CML. DNA demethylating agent 5-aza-2'-deoxycytidine (DAC) was reported to induce cellular senescence but underlying mechanisms remain to be elucidated...

UNLABELLED: Coronary computed tomography angiography (CCTA) is of growing importance in noninvasive diagnosis of coronary artery diseases. The CT data allow evaluation not only of coronary arteries but also of adjacent anatomical territories. Our objective was to review, to analyze, and to quantify the spectrum and the prevalence of extracardiac findings (ECF) in CCTA. Therefore, we searched MEDLINE, EMBASE, and ISI Web of Science. Prior to quantitative analysis, we categorized the ECF of all included studies into clinically significant and clinically non-significant findings...

BACKGROUND: Care of the dying is a significant component of nursing practice particularly in hospitals. Nurses who work in certain areas like oncology, intensive care unit (ICU) face the care of the dying, more so than other units. OBJECTIVES: The survey was conducted to assess nurses' self-perception of their professional capability and comfort in the care of the actively dying. Determine if professional capability and comfort was associated with any of the six demographics characteristics (age, gender, clinical experience, education level, nursing unit, continuing education)...

The enzymatic control of the setting and maintenance of symmetric and non-symmetric DNA methylation patterns in a particular genome context is not well understood. Here, we describe a comprehensive analysis of DNA methylation patterns generated by high resolution sequencing of hairpin-bisulfite amplicons of selected single copy genes and repetitive elements (LINE1, B1, IAP-LTR-retrotransposons, and major satellites). The analysis unambiguously identifies a substantial amount of regional incomplete methylation maintenance, i...

MicroRNAs (miRNAs) represent a class of small (21-23 nucleotides) non-coding RNAs that emerged as key post-transcriptional gene regulators, implicated in numerous physiological and pathological processes. Currently, a main focus of miRNA research is related to the roles of miRNAs in cancer development. The biogenesis and modes of action of miRNAs have not been completely elucidated; however, miRNA-mediated translational repression is involved in the regulation of almost every cellular process. Thus, pathological alterations in miRNA expression signatures are commonly associated with disease development...

Glutathione-S-transferase P1 (GSTP1) gene is commonly silenced by CpG island promoter hypermethylation in prostate, breast, and liver cancers. However, mechanisms leading to GSTP1 repression by promoter hypermethylation in leukemia and its relationship with pathological alterations of the chromatin structure remain poorly understood. A panel of leukemia cell lines was analyzed for their GSTP1 expression, revealing cell lines with high, moderate or no detectable GSTP1 expression. Bisulfite sequencing, methylation-specific PCR and combined bisulfite restriction analysis revealed that GSTP1 promoter was completely methylated in transcriptionally inactive RAJI and MEG-01 cell lines...
