Abstract
We report on the commissioning of a full aperture backscatter diagnostics station for the kilojoule, nanosecond high repetition rate L4n laser operating at a wavelength of 527 nm at the Extreme Light Infrastructure (ELI) - Beamlines, Dolni Brezany, Czech Republic. Light scattered back from laser-plasma interaction into the cone of the final focusing lens is captured and split into different channels to measure the signatures of laser plasma instabilities from stimulated Brillouin scattering, stimulated Raman scattering, and two plasmon decay with respect to back scattered energy, its spectrum, and its temporal profile. The performance was confirmed in a commissioning experiment with more than 800 shots at laser intensities ranging from 0.5 × 1013 to 1.1 × 1015 W cm-2. These diagnostics are permanently installed at ELI Beamlines, and can be used to understand the details of laser-plasma interactions in experiments with kJ and 527 nm light. The large number of shots that can be collected in an experimental campaign will allow us to study the details of the laser-plasma interaction with a high level of confidence.

Abstract
OBJECTIVES The goal of this study was to develop sample preparation method and validate the HPLC method for precise determination of paclitaxel (Ptx) in PLGA submicron particles conjugated with protein vector molecule. METHODS Ptx loaded PLGA submicron particles were formulated by a single emulsification method. PLGA submicron particles were conjugated with alpha fetoprotein third domain (rAFP3d) via standard carbodiimide technique. The obtained conjugate was analyzed using 1525 binary pump and 2487 UV-VIS detector system (Waters, USA) and Reprosil ODS C-18 analytical column with the dimensions of 150mm×4.6mm ID×5μm (Dr. Maisch GmbH, Germany). Sample preparation method was developed utilizing guard cartridge with С18 stationary phase (Phenomenex, USA). HPLC method was validated according to the international conference on harmonization guidelines. RESULTS Efficient sample preparation was achieved using 4% of DMSO pre-dissolution, following by 10min of centrifugation at 4500g. Ptx determination was performed using acetonitrile/0.1% phosphoric acid (50:50 v/v) mobile phase at a flow rate of 1.0mL/min, injection volume of 10μL, and at 227nm. The developed method showed linearity, accuracy and precision in the range from 0.03 to 360μg/mL, with LOD and LOQ values of 0.005 and 0.03μg/mL, respectively. The intra- and inter-day precisions presented RSD values of lower than 2%. CONCLUSION The validated method was successfully applied to calculate Ptx encapsulation efficacy and drug loading in the developed formulation.

Abstract
In this work, we investigate the magnetic structures of (Fe1-xMnx)2AlB2 solid-solution quaternaries in the x = 0 to 1 range using x-ray and neutron diffraction, magnetization measurements, and mean-field theory calculations. While Fe2AlB2 and Mn2AlB2 are known to be ferromagnetic (FM) and antiferromagnetic (AFM), respectively, herein we focused on the magnetic structure of their solid solutions, which is not well understood. The FM ground state of Fe2AlB2 becomes a canted AFM at x ≈ 0.2 , with a monotonically diminishing FM component until x ≈ 0.5 . The FM transition temperature (T C ) decreases linearly with increasing x . These changes in magnetic moments and structures are reflected in anomalous expansions of the lattice parameters, indicating a magnetoelastic coupling. Lastly, the magnetocaloric properties of the solid solutions were explored. For x = 0.2 the isothermal entropy change is smaller by 30% than it is for Fe2AlB2, while the relative cooling power is larger by 6%, due to broadening of the temperature range of the transition.

Abstract
Psilocin and psilocybin are psychoactive components of mushrooms of the genus Psilocybe and many others (Panaeolus, Inocybe, Pluteus etc.). In our republic, several species of Psilocybe with a high content of these components can be found. In the present study, we give a semiquantitative content of psilocin and psilocybin in some of our mushrooms in dry substance (Psilocybe semilanceata, Psilocybe bohemica, Psilocybe arcana, Psilocybe cyanescens, Panaeolus acuminatus sensu Ricken, Inocybe haemacta and Pluteus salicinus). For quantification, the GC/MS instrumentation was applied. Psilocin and psilocybin were silylated by the derivatization agent N-methyl-N-trimet-hylsilyltrifluoroacetamide. As an internal standard, 5-methoxytryptamin was used. The results of this study prove the presence of at least three species of Psilocybe with a high content of psychoactive components growing in our republic: Psilocybe semilanceata, Psilocybe bohemica and Psilocybe arcana.

Abstract
The analysis of the 74 cases of civil aviation accidents have been done from the period 1991-2000, in which 107 persons were killed. The Institute of Aviation Medicine has participated on the investigation of 86.5% crashes in the Czech republic. The majority of accidents happened in the period from april to september, 55.4% cases during weekend days. The male prevalence among bodies was significant, the average age of dead pilots was 43.5 years. Polytrauma was the most frequent cause of death. The medical cause of accident genesis was managed in one case. Heavy problem were almost 11% positive BAC of the investigated crew members. The positive toxicology findings of medical drugs in pilots were sporadic. The type of crashes and their collisions were also analysed.

Abstract
BACKGROUND Although the vaccine research and development network in the United States remains vibrant, its continued success requires maintaining harmonious interaction among its many components. Changing one component is likely to affect the system overall. An examination of case studies of the development of selected vaccines would allow an examination of the network as a whole. This article presents conclusions drawn from the case study review undertaken. OBJECTIVE Successful development of vaccines is a time-intensive process requiring years of commitment from a network of scientists and a continuum of regulatory and manufacturing entities. We undertook this work to shed light on how well the vaccine development system in the United States performs. METHOD The National Vaccine Advisory Committee examined the research and development pathways of several vaccines that reached licensure expeditiously (hepatitis B vaccine, Haemophilus influenzae type b conjugate vaccines); some that became licensed only after considerable delay (oral typhoid Ty21a vaccine, varicella vaccine); some that are at the point of imminent or recent licensure (reassortant Rhesus rotavirus vaccine, which was licensed by the Food and Drug Administration on August 30, 1998) or near submission for licensure (intranasal cold adapted influenza vaccine); and one for which clinical development is slow because of hurdles that must be overcome (respiratory syncytial virus vaccines). RESULTS Some common themes emerged from the reviews of these vaccine "case histories": the expediting influence of a strong scientific base and rationale; the need for firm quantitation of disease burden and clear identification of target populations; the critical role played by individuals or teams who act as "champions" to overcome the inevitable obstacles; availability of relevant animal models, high-quality reagents and standardized assays to measure immune response; the absolute requirement for well designed, meticulously executed clinical trials of vaccine safety, immunogenicity, and efficacy; postlicensure measurements of the public health impact of the vaccine and a track record of the vaccine's safety and acceptance with large-scale use; and the critical need for international collaborations to evaluate vaccines against diseases of global importance that are rare in the United States (eg, typhoid fever). It was clear that the critical step-up from bench scale to pilot lots and then to large-scale production, which depends on a small group of highly trained individuals, is often a particularly vulnerable point in the development process. CONCLUSIONS One fundamental lesson learned is that within the varied and comprehensive US vaccine development infrastructure, multiple and rather distinct paths can be followed to reach vaccine licensure. The National Vaccine Advisory Committee review process should be conducted periodically in the future to ascertain that the US vaccine development network, which has been enormously productive heretofore and has played a leadership role globally, is adapting appropriately to ensure that new, safe, and efficacious vaccines become available in a timely manner.

Abstract
In summary, dextran 40, when given after coronary stent placement, results in a marked decrease in hematocrit within 24 hours. Hematocrit often returns to near baseline levels within 48 hours of stopping dextran. This phenomenon most likely reflects dextran-related hemodilution. This hemodilutional decrease in hematocrit is often misinterpreted as acute blood loss and may result in blood transfusion in patients with low baseline hematocrit. However, far less aggressive anticoagulation regimens, which do not include dextran, are under investigation in patients undergoing coronary stent placement.

Abstract
When parents are faced with the realization that their child has a disability or chronic illness, life is significantly changed. There can be tremendous emotional and economic stress as families seek diagnosis and treatment and face a bewildering search for appropriate programs. Uncertainty about the future and frustration with the present often leave caregivers overwhelmed. For these fragile families, a philosophy of family-centered care in their community is important. Ideally, this seamless system should offer continuity of care from birth through the childhood years and bridge medical, educational, and social services. Only in this environment can we assure that we are saving not only the infant but also the family.
