Opis:
Extraordinary optical transmission and good focusing properties of a two-dimensional scattering structure is presented. The structure is made of Fresnel zone plates periodically arranged along two orthogonal directions. Each plate consists of two ring-shaped waveguides supporting modes that match the symmetry of a circularly polarized incident plane wave. High field concentration at the focal plane is obtained with the short transverse and long longitudinal foci diameters. Optical vortex excitation in a paraxial region of the transmitted field is also observed and analysed in terms of cross-polarisation coupling. The structure presented may appear useful in visualization, trapping and precise manipulations of nanoparticles.

Opis:
Optical lithography or photolithography is well-established optical tool for patterning of substrates, layers or photonic crystals. Therefore, the materials involved in these processes play an important role, especially for the possibility of their further advancements and optimisation. In this review article, we discuss on the role and significance of photoresist materials from various perspectives like their performance in photonic applications and their dependence on various physical and chemical parameters. Further, several emerging now two-dimensional materials like graphene has also been discussed from photonic point of view. We aim to give a short overview of recent developments of such materials in this field.
Fotolitografia jest dobrze znanym procesem pozwalającym na tworzenie wzorów na podłożach, warstwach czy kryształach fotonicznych. W związku z tym materiały wykorzystywane w tym procesie pełnią istotną rolę, zwłaszcza ze względu na dalszy możliwy rozwój dziedziny oraz optymalizację procesu. W tym artykule przeglądowym omawiamy rolę i znaczenie fotorezystu z różnych perspektyw, np. jego wydajność w zastosowaniach fotonicznych czy zależność od różnych parametrów fizycznych i chemicznych. Ponadto, omawiamy wiele powstających obecnie dwuwymiarowych materiałów, jak grafen, z punktu widzenia fotoniki. Naszym celem jest przedstawienie krótkiego przeglądu ostatnich osiągnięć w dziedzinie tego typu materiałów wykorzystywanych w fotolitografii.

Opis:
Introduction and objective. Systemic sclerosis [SSc; scleroderma] is a rare, connective tissue disorder affecting all organs and systems. The primary feature of this disease is a chronic, progressive fibrosis due to excessive production of collagen and other components. There are two subsets of systemic sclerosis: 1) diffused SSc (dSSc), 2) limited SSc (lSSc) and 3) scleroderma without sclerosis (SSSC). The presented review is an attempt to summarize recent data regarding environmental and occupational factors in SSc onset. State of knowledge. There are many factors to be taken under consideration with SSc onset, although a strong correlation has been established for only a few. The most distinct factors are: crystalline silica and organic solvents (such as white spirit, aromatic, aliphatic-chain, chlorinated solvents, ketones, welding fumes). For other factors, which include abstestos, air pollution, other chemicals, silicone breast implants, tobacco smoking, drug reactions, diet influence and exposure to heavy metals, the jury is still out, and their position in SSc onset needs further studies. Conclusions. Although the pathogenesis of scleroderma remains unclear, there is a marked correlation between the onset of SSc and certain environmental or occupational factors.

Opis:
Introduction and objective. Psoriasis isa quite common, chronic and immune-mediated skin disorder. The prevalence of psoriasis differs in various countries, but it is said to affect 2% of the world’s population in general. Psoriasis has many different clinical features but all lesions have the same characteristic: erythema, thickening and scale, although other clinical features are also connected, such as psoriatic arthritis, obesity and metabolic syndrome. All of these may lead to conditions impairing the quality of life. This review is an attempt to summarize recent data regarding environmental factors, together with epigenetic markers and processes playing an important role in psoriasis. State of knowledge. Many different environmental factors play a role in genetically predisposed patients. This is causes epigenetic alternations which may be a linking part in the whole process. Many studies have indicated a connection between psoriasis and various genes and antigens. The presence of HLA-Cw6 is common as well a strong link between its presence and the onset of psoriasis being observed. The main alternations are DNA methylation, histone’s modifications and the role of microRNA. Excessive reaction is usually not present without a triggering factor. Environmental factors are mostly rated, such as drugs, life style and habits (smoking, alcohol), diet, physical trauma (skin injury provoking Koebner phenomenon), stress, microorganism and infections. Conclusions. The correlation between pathogenesis of psoriasis and environmental risk factors, together with epigenetic alternations still require more investigation. Education about diet habits, nutrition, weight loss and healthy lifestyle seems to be important during the treatment of psoriasis.
