A Retrospective Study of 23 Cases: Are Lichenoid Lesions of the Labial Mucosa Induced?

Background Lichen planus (LP) is a pathology that affects the skin and the mucosa. The lips are rarely involved but represent a diagnostic challenge in those cases. Oral lichenoid lesions (OLL) are defined as lesions that resemble oral lichen planus (OLP) but do not fully meet the clinical and/or histologic criteria for OLP.

Climate impact of an optimised gas treatment on old landfills.

It is a well-established fact that the quality and quantity of landfill gas (LFG) start declining after a landfill is closed to further waste intake. Conventional gas treatment and utilisation systems such as flares and gas-driven engines require a certain quality of LFG: specifically, a sufficient methane concentration. Various measures are utilised to maintain the necessary quality of LFG, including a turn-down of gas extraction rates and a shutdown of low-quality gas wells, resulting in a decline of LFG production.

Synthesis and evaluation of antitumor activity of 9-methoxy-1H-benzo[f]chromene derivatives.

Herein, a series of aryl-substituted derivatives of 3-amino-1-aryl-9-methoxy-1H-benzo[f]chromene-2-carbonitriles (4a-4q) were designed and synthesized via reaction of 7-methoxy-2-naphthol with a mixture of appropriate aromatic aldehydes and malononitrile under microwave conditions. Among the tested benzochromene, the known compound 4e and four novel compounds 4f, 4j, 4k, 4m exhibited the highest cytotoxicity towards a panel of six human cancer cell lines MDA-MB-231, A549, HeLa, MIA PaCa-2, RPMI 7951, and PC-3. Compound 4j with 2,4-dichloro substitution on the pendant phenyl ring exhibited the highest broad-spectrum cytotoxicity towards all tested cancer cell lines.

Using Registry Data to Support National Quality Forum Endorsement of Quality Measures for Home-Based Medical Care.

Homebound older adults receiving home-based medical care (HBMC) are high-need, high-cost patients. National Quality Forum (NQF)-endorsed quality measures for this population are lacking. The objective is to describe the reliability and validity testing of 2 new quality measures for such patients to support NQF endorsement.

Modeling of motional EPR spectra using hindered Brownian rotational diffusion and the stochastic Liouville equation.

Electron paramagnetic resonance (EPR) spectra of molecular spin centers undergoing reorientational motion are commonly simulated using the stochastic Liouville equation (SLE) with a rigid-body hindered Brownian diffusion model. Current SLE theory applies to specific spin systems such as nitroxides and to high-symmetry orientational potentials. In this work, we extend the SLE theory to arbitrary spin systems with any number of spins and any type of spin Hamiltonian interaction term, as well as to arbitrarily complex orientational potentials.

Testing the feasibility of augmented digital skin imaging to objectively compare the efficacy of topical treatments for radiodermatitis.

Introduction: Radiation-induced dermatitis (RID) is routinely graded by visual inspection. Inter-observer variability makes this approach inadequate for an objective assessment of the efficacy of different topical treatments. In this study we report on the first clinical application of a new image-analysis tool developed to measure the relevant effects quantitatively and to compare the effects of two different topical preparations used to treat RID.

Enhanced detection of Rickettsia species in Ixodes pacificus using highly sensitive fluorescence in situ hybridization coupled with Tyramide Signal Amplification.

Ixodes pacificus is a host of many bacteria including Rickettsia species phylotypes G021 and G022. As part of the overall goal of understanding interactions of phylotypes with their tick host, this study focused on molecular detection of rickettsiae in ovarian and midgut tissue of I. pacificus by fluorescent in situ hybridization (FISH), PCR, and ultrastructural analysis.

Prospective mid-term results of a consecutive series of a short stem.

A large number of short stem prostheses for hip -arthroplasty have been introduced in the past years. Although there is a large increase of publications about short stems, there is still little data available about survival and revision rates. We report prospectively on the outcome of 84 consecutive NANOS® short stem prostheses in 81 patients.

Increased DNA integrity in colorectal cancer.

Background: Blood-based DNA integrity, defined as the relation of long to small fragments of cell-free circulating DNA, is known to be increased in various types of cancers. Since different DNA fragments and formulae are used by different researchers, conflicting results on the relevance of this marker for cancer diagnosis have been reported.

Patients And Methods: Sera from 24 patients with colorectal cancer, 11 patients with benign gastrointestinal diseases, and 24 healthy individuals were investigated.

Diagnostic relevance of plasma DNA and DNA integrity for breast cancer.

Levels of ALU 115, ALU 247, DNA integrity ([1, 2]) and of the tumour markers CA 15-3 and CEA were analysed in the blood of 152 patients. Plasma levels of ALU 115 and ALU 247 were significantly higher in patients with locally confined (LBC; N = 65), metastatic breast cancer (MBC; N = 47), and benign diseases (N = 12) than in healthy controls (p < 0.001 for all comparisons).

Circulating plasma DNA and DNA integrity in breast cancer patients undergoing neoadjuvant chemotherapy.

Background: In breast cancer patients undergoing neoadjuvant chemotherapy before surgery, biomarkers for predicting response to therapy are urgently required.

Patients And Methods: In 65 patients with locally confined breast cancer who had completed the course of chemotherapy until surgery, plasma DNA biomarkers obtained before and during therapy were evaluated concerning (early) estimation of therapy response. Levels of repetitive ALU 115 and ALU 247 elements as well as DNA integrity calculated according the formulas of Umetani (1) and Wang (2) were correlated with changes in histopathological staging at surgery and compared with conventional tumor markers CEA and CA 15-3.

Prokaryotic multicellularity: a nanopore array for bacterial cell communication.

The transition from unicellular to multicellular life, which occurred several times during evolution, requires tight interaction and communication of neighboring cells. The multicellular cyanobacterium Nostoc punctiforme ATCC 29133 forms filaments of hundreds of interacting cells exchanging metabolites and signal molecules and is able to differentiate specialized cells in response to environmental stimuli. Mutation of cell wall amidase AmiC2 leads to a severe phenotype with formation of aberrant septa in the distorted filaments, which completely lack cell communication and potential for cell differentiation.

Transition State Search Using a Guided Direct Inversion in the Iterative Subspace Method.

A transition state optimization method using a guided energy-represented direct inversion in the iterative subspace (gEn-DIIS) algorithm is introduced and compared with the quasi-Newton rational function optimization (RFO) method. A hybrid technique that employs a combination of RFO and guided DIIS methods at various stages of convergence is presented. A set of test molecules is optimized for comparison using the hybrid method with gEn-DIIS and the traditional RFO methods.

Cell wall amidase AmiC1 is required for cellular communication and heterocyst development in the cyanobacterium Anabaena PCC 7120 but not for filament integrity.

Filamentous cyanobacteria of the order Nostocales display typical properties of multicellular organisms. In response to nitrogen starvation, some vegetative cells differentiate into heterocysts, where fixation of N(2) takes place. Heterocysts provide a micro-oxic compartment to protect nitrogenase from the oxygen produced by the vegetative cells.

Circulating nucleosomes and biomarkers of immunogenic cell death as predictive and prognostic markers in cancer patients undergoing cytotoxic therapy.

Introduction: Immunogenic cell death markers are released from apoptotic and necrotic cells upon pathologic or therapeutic causes and stimulate the innate and adaptive immune system. Cell death products such as nucleosomes, damage-associated molecular pattern (DAMP) molecules such as the high-mobility group box 1 protein (HMGB1) and its receptor of advanced glycation end products (sRAGE) are supposed to play an essential role in driving this process. However, this immunogenic activation may have dual effects, either by sensitizing the immune system for more efficient tumor cell removal or by creating a favorable tumor microenvironment that facilitates tumor growth, proliferation and invasiveness.

Methodological and preanalytical evaluation of a RAGE immunoassay.

Background: Soluble receptor of advanced glycation end products (sRAGE) is a promising biomarker for the prognosis and the monitoring of cancer and of acute diseases such as trauma and sepsis.

Materials And Methods: We investigated the methodological characteristics of an ELISA for sRAGE (R&D Diagnostics) including intra- and inter-assay imprecision, dilution linearity and differences in various serum and plasma materials. Furthermore, the influence of various preanalytical factors such as time and storage temperature before and after centrifugation prior to definite deep freezing, as well as multiple freeze-thaw cycles, were tested.

Background: Soluble high-mobility group box 1 (sHMGB1) is a promising biomarker for the prognosis and the monitoring of cancer and of acute diseases such as trauma and sepsis.

Materials And Methods: We investigated the methodological characteristics of an ELISA for sHMGB1 (Shino-Test, Tokyo, Japan and IBL, Hamburg, Germany) including intra- and inter-assay imprecision, dilution linearity and differences in serum and plasma materials. Furthermore, the influence of various preanalytical factors such as time and storage temperature before and after centrifugation prior to definite deep freezing, as well as multiple freeze-thaw cycles were tested.

Integrating new approaches for clinical development: translational research and relative effectiveness.

Translational research and relative effectiveness are being incorporated into drug development programs to meet the demands for more robust evidence generation to support the value of new therapies. Translational research includes translating basic research into clinical practice, controlled clinical trials into potential clinical implications, evidence-based guidelines into routine clinical practice and standard practices into population health. These research concepts link with real-world outcomes, and feed into each other to improve the efficiency of research.

Integrating scientific and real-world evidence within and beyond the drug development process.

Newly developed healthcare treatments face a complex environment with many stakeholders who can accelerate or decelerate adoption, most notably the healthcare system payers. Understanding and integrating their needs earlier in clinical development will ensure a smoother transition from bench to bedside. This paper describes a new approach to shaping a more effective complementary process of 'value' evidence generation both in and outside the clinical drug development process.

A framework for pharmaceutical value-based innovations.

The rapidity of change and increasing complexity of today's healthcare environment dictates that pharmaceutical companies refine their drug development process to ensure that products provide maximal value to consumers. Innovation should receive the support and encouragement it deserves but the balance between cost of therapy and enhanced benefits to the end users, the patients, must not be compromised. The health or quality-of-life outcomes that therapies are likely to achieve need to be clearly stated for patients so they know what to expect before beginning treatment.

The morphogene AmiC2 is pivotal for multicellular development in the cyanobacterium Nostoc punctiforme.

Filamentous cyanobacteria of the order Nostocales are primordial multicellular organisms, a property widely considered unique to eukaryotes. Their filaments are composed of hundreds of mutually dependent vegetative cells and regularly spaced N(2)-fixing heterocysts, exchanging metabolites and signalling molecules. Furthermore, they may differentiate specialized spore-like cells and motile filaments.
