Grating inscription in a Ga-doped silica core fiber (∼5 wt. % Ga) has been demonstrated using ArF (193 nm) and KrF (248 nm) excimer lasers. In a comparative study with germanosilicate fiber with similar Ge concentration, a Ga-doped silica core fiber shows greater photosensitivity to an ArF excimer laser due to the higher absorbance in the region of 190-195 nm. In addition, the photosensitivity of a Ga-doped silica core fiber has been greatly enhanced with hydrogenation. Ga-doped fibers are poten...
Angiotensin II receptor blockers (ARBs) are widely used to treat hypertension and heart failure. Photosensitivity reactions are cutaneous adverse events due to exposure to a drug and either ultraviolet or visible radiation. Among the ARB class, this type of adverse drug reaction is labeled only for losartan.
The discovery of the first microRNA (miRNA) over 20 years ago has ushered in a new era in molecular biology. There are now over 2000 miRNAs that have been discovered in humans and it is believed that they collectively regulate one third of the genes in the genome. miRNAs have been linked to many human diseases and are being pursued as clinical diagnostics and as therapeutic targets. This review presents an overview of the miRNA pathway, including biogenesis routes, biological roles, and clinical approaches.
The elucidation of the interactions between a protein and a ligand or proteins is a key issue for understanding of functional processes of various proteins, enzymes and receptors in biological organisms, system biology and drug design. One of the most important matters in these problems is the accurate estimation of binding free energy between a protein and a ligand or proteins. In the present review, we overview various techniques and introduce a new technique for estimation of binding free energy calculat...
Glioma is the most common primary brain tumor, accounting for 30% to 40% of all intracranial tumors. About half of all gliomas in adults are glioblastomas. Patients with glioblastoma have a poor prognosis, with a median survival of one year despite aggressive therapy and a five year mortality of over 95%. Although considerable progress has been made in the technical proficiencies of surgical and radiation oncology, the overall impact of these advances on clinical outcomes has been disappointing. Recent e...
With the continuous development of biological experiment technology, more and more data related to uncertain biological networks needs to be analyzed. However, most of current alignment methods are designed for the deterministic biological network. Only a few can solve the probabilistic network alignment problem. However, these approaches only use the part of probabilistic data in the original networks allowing only one of the two networks to be probabilistic. To overcome the weakness of current approaches,...
In the field of small-molecule studies, vast efforts have been put forth in order to comprehensively characterize and quantify metabolites formed from complex mechanistic pathways within biochemical and biological organisms. Many technologies and methodologies have been developed to aid understanding of the inherent complexities within biological metabolomes. Specifically, mass spectroscopy imaging (MSI) has emerged as a foundational technique in gaining insight into the molecular entities within cells, tis...
With the rapid developments of nanotechnology, chances of exposing nanoscale particles to humans (e.g., workers and consumers) also increase correspondingly, which raises serious concerns on their biosafety. Entrance of nanoparticles into diverse biological environment endows them with new and dynamic biological identities as the so-called nanoparticle-protein corona. Therefore, understanding the role of these nanoparticle-protein coronas and resulting biological responses is crucial, as it helps to clarify...
Covering: 1980s-2014In this study, the biological properties of natural abietane-type diterpenoids with an aromatic C ring are reviewed. An overview of the synthetic studies of this group of abietanes, including dehydroabietic acid, callitrisic acid and ferruginol, is presented. The review contains about 160 references.
Motif mining has always been a hot research topic in bioinformatics. Most of current research on biological networks focuses on exact motif mining. However, due to the inevitable experimental error and noisy data, biological network data represented as the probability model could better reflect the authenticity and biological significance, therefore, it is more biological meaningful to discover probability motif in uncertain biological networks. One of the key steps in probability motif mining is frequent p...
The peak sodium current underlies excitability and conduction in heart muscle, but a late sodium current flowing after the peak contributes to maintaining and prolonging the action potential plateau, and also to intracellular sodium loading, which in turn increases intracellular calcium with consequent effects on arrhythmia and diastolic function. Late sodium current is pathologically increased in both genetic and acquired heart disease, making it an attractive target for therapy to treat arrhythmia, heart ...
L-Theanine (γ-glutamylethylamide) is a unique non-protein amino acid that is naturally found in tea plants. It contributes to the umami taste and unique flavor to green tea infusion, and thus its content in tea leaves highly impacts the tea quality and price. In addition to the graceful taste, it has been proved to have many beneficial physiological effects, especially promoting relaxation and improving concentration and learning ability. Based on these promising advantages, L-theanine has been commerciall...
We aim to give an overview of the recent progress in the knowledge of the genetic component of vasculitides.
Metabolomics is emerging as a powerful tool for studying metabolic processes and in recent years, the applications in the area of nutrition have risen rapidly. The present review gives an overview of the current applications in the field of nutrition and identifies areas in need of advancement.
Chagas disease, the American trypanosomiasis, is an important neglected tropical illness caused by the flagellate protozoan Trypanosoma cruzi (Kinetoplastida, Trypanosomatidae) and transmitted by insects of the subfamily Triatominae (Hemiptera: Reduviidae). Here we provide an overview on the current knowledge about Triatominae ecology, its association with human, T. cruzi infection and the immediate consequences of habitat fragmentation. We also discuss the geographic distribution of the species and the imp...
Biological systems respond to and interact with surfaces. Gas plasma provides a scalable surface treatment method for designing interactive surfaces. There are many commercial examples of plasma-modified products. These include well plates, filtration membranes, dispensing tools, and medical devices. This chapter presents an overview of gas plasma technology and provides a guide to using gas plasma for modifying surfaces for research or product development.
The reasons for delayed fracture healing or non-union formation are multifactorial. Mechanical factors are well known to influence the process of fracture healing. However, there is a lack of knowledge about the biological conditions that have to be achieved for adequate bone healing. Treatment of non-unions is still demanding and we have only poor options to stimulate the bone healing process. Therefore, it is important to optimise the biological conditions to avoid non-union formation. Beside patient-rela...
