Opis:
Lutein and zeaxanthin are naturally occurring xanthophylls, mainly present in green, leafy vegetables and egg’s yolk. Their presence is connected with blue spectrum light absorbance, including UV. This property, and fact, that these xanthophylls are accumulated by human eye’s macula, leads to eye’s protective functions of them including protection from age-related macular degeneration (AMD). Also, antioxidative features of lutein and zeaxanthin are boosting overall health of human body. Numerous studies proves anti-inflammatory and protective attributes of these compounds, based on many, different mechanisms. One of them is regulating redox potential in cells, and impact on expression of linked genes. In preventing of eye diseases, an important gene that is regulated by lutein and zeaxanthin is the Nrf2 gene, whose increased activity leads to optimizing the cellular response to reactive oxygen species (ROS) and preventing related diseases. Other research confirms antiproliferative properties of mentioned compounds in case of certain human cancer cell lines. There are e.g.: HepG2 (hepatitis cancer), MCF-7 (breast cancer), which treated in vitro with lutein solution showed reduction of cell growth. Lutein alone, during in vivo studies conducted on mice, exhibited also radioprotective properties, positively affecting the vitality of animals. Lutein provides also increasing of tolerance to UV radiation, reducing inflammatory processes in the skin and preventing oncogenesis. Low intake of lutein and zeaxanthin, associated with “western diet”, rich in simple carbohydrates and processed food, common in developed countries, including Poland, is linked with diabetes and obesity incidence. Assuming, lutein and zeaxanthin significantly affect the well-being of the human body, and their appropriate amount in diet can help reduce risk of many diseases. For supplementation, the optimized dosage of these xanthophylls includes doses of 10 mg for lutein and 2 mg for zeaxanthin, and it is recommended to consume along with fats or meals rich in fats.

Opis:
The aim of this study was to determine the effect of different vegetable protein sources in complete finisher diets on the fattening performance of pigs, carcass quality and the nutritional value of pork. A feeding trial was performed on 72 finishing pigs divided into 3 experimental groups, which were fed complete finisher diets containing the following sources of vegetable protein: group S – genetically modified soybean meal, group P – low-tannin pea ‘Albatros’ and 00-rapeseed meal, group B - high-tannin faba bean ‘Nadwiślański’ and 00-rapeseed meal. Performance was evaluated based on daily gains and feed efficiency for the fattening period from 65 to 105 kg body weight. Defined indicators for slaughter carcasses, chemical composition and fatty acid profile of m. longissimus dorsi lumborum were assessed. Significant decrease (by 5.1%) in the average daily gain of pigs was observed in group B. Backfat thickness was also significantly higher in the carcasses of group B pigs, in comparison with group S. The intramuscular fat content of m. longissimus dorsi lumborum was significantly lower in group P than in the remaining groups. The replacement of genetically modified soybean meal with low-tannin pea ‘Albatros’ contributed to a decrease in the concentrations of saturated fatty acids (P < 0.05) and an increase in the levels of unsaturated fatty acids in the intramuscular fat of m. longissimus dorsi lumborum. A more desirable UFAs / SFAs ratio and lower total cholesterol was observed in the meat of pigs fed a diet containing mixtures of seed peas and faba bean.

Opis:
The objective of this study was to determine the effect of dietary protein restriction in finishing pigs on the fat content, fatty acid profile, and atherogenic and thrombogenic indices of m. longissimus dorsi. A feeding trial was performed on 45 crossbred [(Polish Landrace x Polish Large White) x Duroc] finishing pigs with an average initial body weight of 65 kg. The animals were divided into experimental groups and were fed finisher diets with different levels of total protein and total lysine: group S-c- standard protein level, O – protein level reduced by 15% relative to the standard level, O+AA – protein level reduced by 15% and supplemented with crystalline lysine to the standard level. The intramuscular fat content, fatty acid profile and health-promoting properties of m. longissimus dorsi were determined. A 15% reduction in total protein levels in diets for finishing pigs insignificantly increased the intramuscular fat content of m. longissimus dorsi, but had no influence on the total concentrations of saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs). The supplementation of low-protein diets with crystalline lysine decreased the intramuscular fat content of m. longissimus dorsi, decreased the concentrations of margaric-oleic acid (C17:1) and gadoleic acid (C 20:1), and increased α–linolenic acid (C18:3) levels. Meat from pigs fed a low-protein diet supplemented with lysine was characterized by a lower (more desirable) n-6/n-3 PUFA ratio and provide more atherogenic and trombogenic properties.

Extreme ultraviolet (EUV) covers wavelength range from about 5 nm to 50 nm. That is why EUV is especially applicable for imaging and patterning on nanometer scale length. In the paper periodic nanopatterning realized by interference lithography and high resolution holographic nanoimaging performed in a Gabor in-line scheme are presented. In the experiments a compact table top EUV laser was used. Preliminary studies on using a laser plasma EUV source for nanoimaging are presented as well.

Opis:
The surface modification of polyethylene terephthalate (PET) polymer films has been performed by irradiation of extreme ultraviolet photons to investigate the effect of surface structuring on wettability control. For biomedical engineering applications, surface structuring and wettability control of PET films could enhance the polymer biocompatibility by promoting cell adhesion and consequently proliferation. The PET films are irradiated with laser plasma extreme ultraviolet source based on double stream gas puff target under different environments. The extreme ultraviolet modified PET film surfaces are characterized by atomic force microscopy and WCA goniometer. The extreme ultraviolet surface modification resulted in the formation of nano- and microstructuring on the polymer surfaces. The surface structuring consequently increased WCA making the PET surfaces more hydrophobic. The results demonstrate the direct relationship between surface roughness and hydrophobicity for extreme ultraviolet modified PET samples.

Opis:
In this work results of investigations concerning nanostructuring of polymers and some other solids using a laser-plasma extreme ultraviolet source are presented. The plasma radiation was produced using a gas puff target and focused with a gold-plated grazing incidence ellipsoidal collector. Decomposition process of polymers was investigated using a quadrupole mass spectrometer. Different kinds of micro- and nanostructures created in near-surface layers of the materials were investigated using scanning electron microscope. Forms of the structures depend on a particular material and the extreme ultraviolet exposure. In case of some polymers even a single shot is sufficient for creation of the visible changes in surface morphology. In case of inorganic solids visible changes require usually the exposure with tens or hundreds of extreme ultraviolet pulses.

Opis:
Laser plasma with temperature of the order of tens eV can be an efficient source of extreme ultraviolet (EUV). The radiation can be focused using different kind of optics, giving sufficient fluence for some applications. In this work we present results of investigations concerning applications of a laser plasma EUV source based on a double stream gas puff target. The source was equipped with two different grazing incidence collectors. One of them was a multifoil collector, the second one was an axisymmetrical ellipsoidal collector. The multifoil mirror was used mainly in experiments concerning micromachining of organic polymers by direct photo-etching. The experiments were performed for different polymers that were irradiated through a fine metal grid as a contact mask. The smallest element of a pattern structure obtained in this way was 5 μm, while the structure height was 50 μm giving an aspect ratio about 10. The laser-plasma EUV source equipped with the axisymmetrical ellipsoidal collector was used for surface modification of organic polymers and inorganic solids. The surface morphology after irradiation was investigated. Different forms of micro- and nanostructures were obtained depending on material and irradiation conditions.

Opis:
In this work we present recent results on nanoscale imaging in the extreme ultraviolet and soft X-ray spectral ranges, describing three novel imaging systems dedicated for high spatial resolution imaging of nanoscale objects with the extreme ultraviolet and soft X-ray radiations. The extreme ultraviolet and soft X-ray full field microscopes operate at 13.8 nm and 2.88 nm wavelengths and are capable of imaging of nanostructures with a sub-50 nm spatial resolution. A soft X-ray contact microscope operates in the "water-window" spectral range from 2.3 to 4.4 nm wavelength, to obtain images of an internal structure of the investigated object in a thin surface layer of soft X-ray light sensitive photoresist. The development of such compact imaging systems may, in the near future, be important from the point of view of new research related to biological, material science, and nanotechnology applications. Such preliminary applications are also shown in the studies of biological samples, including carcinoma cells, diatoms, and neurons.

During the last two decades, the development of laboratory scale extreme ultraviolet sources has been intensified due to growing interest in use of extreme ultraviolet photons for various applications in science and technology. In this study, we present a potential application of extreme ultraviolet sources for surface modification of polymers to be used as substrates for cancer cell identification. The surface modification of polytetrafluoroethylene (PTFE) polymer samples was performed by a lab scale compact laser-plasma extreme ultraviolet source based on a double-stream gas-puff target. The gas target was irradiated with a 3 ns/0.8 J Nd:YAG laser pulse at 10 Hz. Reference HCV29 non-malignant transitional epithelium and T24 bladder cancer cells adhesion and proliferation studies on pure and extreme ultraviolet sources modified PTFE surfaces were performed. The extreme ultraviolet modified surfaces demonstrated regular increase in cancer cell proliferation comparing to pristine sample. Initial results indicate that extreme ultraviolet treated substrates can facilitate the identification of cancer cells.

Photons were generated by various plasma sources providing nanosecond and sub-nanosecond pulses of extreme ultraviolet, soft X-ray and X-ray radiation. DNA strand breaks were determined by agarose gel electrophoresis. Higher radiation chemical yields of both single and double strand breaks were found using picosecond and nanosecond sources of extreme ultraviolet and X-ray radiation.

Opis:
Soft X-ray contact microscopy potentially allows imaging of wet living biological specimens at a spatial resolution higher than optical microscopy and without many of the constraints of scanning electron microscopy. In this paper, we present the development of a laboratory scale contact microscope that uses a laser produced plasma soft X-ray source. The source is based on a double-stream gas-puff target approach and it operates in the "water window" spectral range which enables to capture images of biological samples with a natural contrast. In the preliminary experiments the contact microscope system has been used for imaging of fixed and dried non-malignant HCV29 human bladder cell lines cultured on polymethyl methacrylate photoresists. The samples were exposed with 150 pulses of soft X-rays as an initial test to demonstrate the possibility of image formation. The soft X-ray contact images registered in the photoresists exhibit high resolution in the atomic force microscopy topography which indicates the potential application of soft X-ray contact microscopy in life science to examine small features as small as few tens of nm. The technique could also be used for living cell imaging with further optimization of the microscope system and development of a special specimen holder. The details of the soft X-ray contact microscopy technique and the experimental results are presented and discussed.
