OBJECTIVE The aim of the present study was to assess the effectiveness of an UVA1 355 nm laser (Alba 355) for treatment of mild, moderate, and severe psoriasis. BACKGROUND DATA Psoriasis is an immune-inflammatory and proliferative skin disease. During the past few years, the instrumental treatment by UV radiation has been successfully described, either alone or in combination with topical and...

In this work porous commercially pure Ti substrates fabricated by spacer-holder technique (50 vol% NH4HCO3 and three range pores sizes, 100–200 μm, 250–355 μm 355–500 μm) were coated with two types of gelatinous materials, one as a linear polymer (non-crosslinked) another crosslinked. The role the crosslink, well morphology, size degree interconnectivity gelatins coatings on their tribo-mechani...

Cnidarians are the most primitive animals to possess a nervous system. This phylum is composed of the classes Scyphozoa (jellyfish), Cubozoa (box jellyfish), and Hydrozoa (e.g., Hydra, Hydractinia), which make up the subphylum Medusozoa, as well as the class Anthozoa (sea anemones and corals). Neuropeptides have an early evolutionary origin and are already abundant in cnidarians. For example, f...

Neutral vanadium oxide clusters are studied by photoionization time-of-flight (TOF) mass spectroscopy, electronic spectroscopy, and density functional theory (DFT) calculations. Mass spectra of vanadium oxide clusters are observed by photoionization with lasers of three different wavelengths: 118, 193, and 355 nm. Mechanisms of 118 nm single photon ionization and 193 and 355 nm multiphoton ioni...

We present a picosecond Fe K-edge absorption study of photoexcited ferrous and ferric hexacyanide in water under 355 and 266 nm excitation. Following 355 nm excitation, the transient spectra for the ferrous and ferric complexes exhibit a red shift of the edge reflecting an increased electron density at the Fe atom. For the former, an enhanced pre-edge transition is also observed. These observat...

BACKGROUND Toxoplasma gondii infection causes toxoplasmosis, an infectious disease with worldwide prevalence. The limited efficiency of drugs against this infection, their side effects and the potential appearance of resistant strains make the search of novel drugs an essential need. We examined Eurycoma longifolia root extract and fractions as potential sources of new compounds with high activ...
