Drug-induced photosensitivity: Photoallergic and phototoxic reactions.

Drug-induced photosensitivity refers to the development of cutaneous disease due to the interaction between a given chemical agent and sunlight. Photosensitivity reactions can be classified as phototoxic or photoallergic. Sometimes, there is an overlap between these two patterns, making their distinction particularly difficult for the clinician. We review the drugs that have been implicated as photosensitizers, the involved mechanism, and their clinical presentations. The main topical agents that cause cont...

Neoadjuvant approach for nonsmall cell lung cancer: overview of the current issues.

Despite the large numbers of studies, role of neoadjuvant chemotherapy and neoadjuvant chemoradiotherapy is debated. This approach would increase resectability in locally advanced patients, and improve surgical outcome in resectable patients. Thus, an overview of recent literature is relevant to highlight the current issues.

Synthesis, Structure, Band Gap, and Near-Infrared Photosensitivity of a New Chalcogenide Crystal, (NH4)4Ag12Sn7Se22.

A new chalcogenide crystal, (NH4)4Ag12Sn7Se22 (FJSM-STS), has been solvothermally synthesized. The crystal structure, which is composed of arrays of [Sn3Se9]n(6n-) chains interconnecting [SnAg6Se10]n(10n-) and [Ag3Se4]n(5n-) layers, is unprecedented among the reported A/Ag/Sn/Q (A = cation; Q = S, Se, and Te) compounds. Optical absorption together with theoretical calculations of the band structure indicate a direct band gap of 1.21 eV for FJSM-STS, which is close to the ideal band gap to maximize the photo...

Multifunctional biomaterial coatings: synthetic challenges and biological activity.

A controlled interaction of materials with their surrounding biological environment is of great interest in many fields. Multifunctional coatings aim the simultaneous modulation of several biological signals. They can consist of various combinations of bioactive, and bioinert components as well as of reporter molecules to improve cell-material contacts, prevent infections or to analyze biochemical events on the surface. However, specific immobilization and particular assembly of various active molecules are...

An overview of the biological metal uptake pathways in Pseudomonas aeruginosa.

Biological metal ions, including Co, Cu, Fe, Mg, Mn, Mo, Ni and Zn ions, are necessary for the survival and the growth of all microorganisms. Their biological functions are linked to their particular chemical properties: they play a role in structuring macromolecules and/or act as co-factors catalyzing diverse biochemical reactions. These metal ions are also essential for microbial pathogens during infection: they are involved in bacterial metabolism and various virulence factor functions. Therefore, during...

Dipeptidyl peptidase 9 substrates and their discovery: current progress and the application of mass spectrometry-based approaches.

The enzyme members of the dipeptidyl peptidase 4 (DPP4) gene family have the very unusual capacity to cleave the post-proline bond to release dipeptides from the N-terminus of peptide/protein substrates. DPP4 and related enzymes are current and potential therapeutic targets in the treatment of type II diabetes, inflammatory conditions and cancer. Despite this, the precise biological function of individual DPPs, other than DPP4, and knowledge of their in vivo substrates remains largely unknown. For many year...

Getting a grip on glycans: A current overview of the metabolic oligosaccharide engineering toolbox.

This review discusses the advances in metabolic oligosaccharide engineering (MOE) from 2010 to 2016 with a focus on the structure, preparation, and reactivity of its chemical probes. A brief historical overview of MOE is followed by a comprehensive overview of the chemical probes currently available in the MOE molecular toolbox and the bioconjugation techniques they enable. The final part of the review focusses on the synthesis of a selection of probes and finishes with an outlook on recent and potential up...

An overview of topic modeling and its current applications in bioinformatics.

With the rapid accumulation of biological datasets, machine learning methods designed to automate data analysis are urgently needed. In recent years, so-called topic models that originated from the field of natural language processing have been receiving much attention in bioinformatics because of their interpretability. Our aim was to review the application and development of topic models for bioinformatics.

An Overview of Fat Grafting.

Optical coherence tomography and confocal laser endomicroscopy in pulmonary diseases.

Current imaging techniques (X-ray, computed tomography scan, ultrasound) have limitations in the identification and quantification of pulmonary diseases, in particular, on highly detailed level. The purpose of this review is to provide an overview of the current knowledge of innovative light- and laser-based imaging techniques that might fill this gap.

Anti‑cytokine therapy for psoriasis - not only TNF‑α blockers. Overview of reports on the effectiveness of therapy with IL‑12/IL‑23 and T and B lymphocyte inhibitors.

TNF‑α inhibitors - infliximab, etanercept and adalimumab - can be used in the treatment of psoriasis vulgaris and psoriatic arthritis, along with other inhibitors of proinflammatory cytokines, such as interleukin‑12 (IL‑12) and IL‑23. This paper presents the results of research on the use of biological drugs other than the tumor necrosis factor blockers (TNF‑α), namely inhibitors of IL‑12 and IL‑23 (ustekinumab), T‑cell inhibitors (alefacept and efalizumab), B‑cell inhibitors (rituximab)...

Low-dose radiation may be a novel approach to enhance the effectiveness of cancer therapeutics.

It has been generally accepted that both natural and man-made sources of ionizing radiation contribute to human exposure and consequently pose a possible risk to human health. However, accumulating evidence has shown that the biological effects of low-dose radiation (LDR) are different from those of high-dose radiation. LDR can stimulate proliferation of normal cells and activate their defense systems, while these biological effects are not observed in some cancer cell types. Although there is still no conc...

Effects of Mindfulness on Diabetes Mellitus: rationale and overview.

Diabetes mellitus (DM) is an emerging global healthcare problem and its prevalence is increasing at an alarming rate. Despite improvements in both medical and pharmacological therapies, a complex medical condition may demand a diversified approach, such as: drug therapy, healthy diet and behavior exercises, diabetes education programs, adherence to medical treatment and active participation of the patients in their lifestyle changes, such as stress management. The concept of mindfulness is here defined as t...

Continuous electroencephalographic-monitoring in the ICU: an overview of current strengths and future challenges.

In ICUs, numerous physiological parameters are continuously monitored and displayed. Yet, functional monitoring of the organ of primary concern, the brain, is not routinely performed. Despite the benefits of ICU use of continuous electroencephalographic (EEG)-monitoring (cEEG) is increasingly recognized, several issues nevertheless seem to hamper its widespread clinical implementation.

The Role of Nutrition in Frailty: An Overview.

Inadequate nutritional intake is an important modifiable risk factor for frailty. Existing evidence supports the importance of adequate dietary quantity and especially quality to ensure sufficient intakes of energy, protein and micronutrients. However, to date no nutritional intervention or supplementation concept has emerged as being effective for the prevention or treatment of frailty. Further research, including specifically the group of frail older persons and those at risk of frailty, and focussing on ...
