Opis:
Multiple sclerosis (MS) is the most common autoimmune disease affecting the central nervous system, characterized by the presence of scattered foci of demyelination in the brain and spinal cord. Magnesium (Mg) has a significant influence on the nervous system and the immune system. The aim of this study was to evaluate the influence of the concentration of Mg in the serum on the ability status of patients with MS. The study group consisted of 101 adults with diagnosed relapsing remitting MS. All participants were investigated on the Expanded Disability Status Scale. The control group included 41 people. The concentration of Mg in the serum was determined by the flame atomic absorption spectrometry method. The patients completed a survey and a 24-hour dietary interview. In patients with MS, the percentage of respondents with normal magnesium content was significantly lower than in the control group (p < 0.05). The study proved that patients with normal Mg serum concentration levels were in better clinical condition, particularly with respect to the function of the pyramidal tract (p = 0.007) and sphincters (p = 0.002), than patients with inadequate levels of Mg in the serum. External factors such as gender, smoking, immunomodulating medications or dietary supplements of Mg were found to have no effect on the concentration of Mg in the serum of MS patients. The results of our study suggest that an abnormal concentration of Mg in the serum of MS patients should be recognized and corrected, as this may improve the health status of people with MS.

Opis:
Introduction:S100 calcium-binding protein B (S100B) is a biochemical marker of astroglial damage. Purpose: To assess the pathophysiological implications of S100B concentrations in blood plasma and cerebrospinal fluid of patients with neurodegenerative central nervous system disorders. Materials and Methods: In this study, we determined and compare S100B concentrations in blood plasma and cerebrospinal fluid obtained from subjects diagnosed with Alzheimer's disease (n=20), amyotrophic lateral sclerosis (n=12), multiple sclerosis (n=40) and the reference group (n=20), using enzyme-linked immunosorbent assay. Results: Concentrations of S100B in plasma collected from patients diagnosed with Alzheimer's disease (252,38±183,50 pg/mL) and multiple sclerosis (164,92±250,14 pg/mL) were above laboratory standards, but in patients with amyotrophic lateral sclerosis (53,96±56,92 pg/mL) and the reference group (2,12 pg/mL) were below laboratory norms (N>75 pg/mL). Concentrations of S100B in plasma collected from patients with Alzheimer's disease (252,38±183,50 pg/mL) were significantly higher than in patients with amyotrophic lateral sclerosis (53,96±56,92 pg/mL) (p<0,029). Concentrations of S100B in CSF collected from the reference group (546,96±236,62 pg/mL) and from patients with Alzheimer's disease (587,53±189,57 pg/mL), amyotrophic lateral sclerosis (404,41±179,56 pg/mL), multiple sclerosis (462,03±146,01 pg/mL) were very similar, and none of pairwise comparisons reached statistical significance. Conclusions: Results of our studies indicate the importance of S100B protein concentration assessment in blood in central nervous system disorders differential diagnostics.

Opis:
In the paper the application of multicore optical fibres in phased-locked high power lasers is presented. The manufacturing and properties of multicore active optical fibres were presented. The thermally stable aluminosilicate glass doped with $Nd^{3+}$ (0.5 mol%) ions were melted and used as cores in manufactured multicore optical fibres. Two configurations of double clad multicore optical fibres with the circular array containing 15 and 30 $Nd^{3+}$ doped cores on ring inside a large pump clad were realized. Absorption and luminescence spectra of obtained glasses and fibres were presented. An external plane mirror located at certain distance of the array forms the basic Talbot cavity. The possibilities of mode selection and phase-locking by using Talbot resonator applied to fabricated multicore fibres were investigated.

Opis:
In the article the cooperative energy transfer in GeO₂-GaO-BaO glass system doped with $Yb^{3+}//Tb^{3+}$ under 980 nm laser diode excitation was investigated. The influence of $Tb^{3+}$ concentration on the luminescent properties was determined. Measured strong luminescence at 489, 543, 586, 621 corresponds to $\text{}5D_4 \rightarrow \text{}^7 F_{J} $ (J = 6, 4, 3) transitions and luminescence at 381, 415, 435 nm results from $\text{}5 D_3, \text{}^5 G_6 \rightarrow \text{}^7 F_{J}$ (J = 6, 5, 4) transitions. Mechanism and energy diagram involved in observed emission were discussed. The highest upconversion emission intensity was obtained in the germanate glass doped with 0.7Yb₂O₃/0.7Tb₂O₃.

Opis:
In the article there are presented two different series of glass: fluorophosphate with molar composition: $65P_2O_5-8Al_2O_3-$ $2BaO-5BaF_2-6ZnF_2-$ $5Na_2O-$ $6MgF_2-3B_2O_3$ and antimony glasses $40Sb_2O_3-$ $3Al_2O_3-$ $57SiO_2$ doped with $Nd^{3+}$ and $Yb^{3+}$ ions. Dopant contents influence efficient spatial overlapping of emission level for neodymium and absorption level for ytterbium was analyzed. While exciting the produced glasses with a laser diode (λ = 808 nm) a broad luminescence spectrum (Δλ = 100 nm) has been obtained in both cases in the vicinity of 1 μm, being the superposition of the following transitions: $\text{}^4F_{3//2} \rightarrow {\text{}^4I_{11//2}}$ for $Nd^{3+}$ and $\text{}^2F_{5//2} \rightarrow {\text{}^2F_{7//2}}$ for $Yb^{3+}$. Based on the luminescence measurements the probability of non-radiative energy transfer was described. Because of a small difference in energy ( ≈1190 $cm^{-1}$) between the laser levels of neodymium and ytterbium the resonant process of energy transfer has been obtained.

Opis:
The paper presents luminescence properties of telluride glass doped with $Yb^{3+}//Tm^{3+}$ ions. Strong blue emission at 477 nm corresponding to the transition $\text{}^1 G_4 \rightarrow \text{}^3 H_6$ in thulium ions was measured under the excitation of a 976 nm diode laser. The dependence of the upconversion emission upon the thulium ions concentration was studied in order to determine the optimal ion content. The results showed that intensity of upconversion emission enhances, with the increase of $Tm^{3+}$ content up to 0.1 mol.%. The most effective energy transfer $Yb^{3+} \rightarrow Tm^{3+}$ occurs in the glassy matrix with molar ratio of dopant 1 $Yb^{3+}$ : 0.1 $Tm^{3+}$. Double-clad optical fibre was made of glass with the highest upconversion intensity at the wavelength of λ = 477 nm (TGPF101). As a result of optical excitation (λ = 976 nm) of the produced optical fibre, an additional emission line, which was not noticed in the glass, was observed at the wavelength of 351 nm corresponding to the $\text{}^1 D_2 \rightarrow \text{}^3 H_6$ transition.

Opis:
In the paper the beam quality of the phase-locked multicore fibre lasers was investigated. The beam quality factor (BQF) of the coherently combined beam of the multicore fibre lasers should be determinate as the laser optical output power in a central peak far-field bucket divided by the total optical output power radiating from the effective near-field. Classical $M^2$ factor is not proper for evaluating the beam quality of phase-locked multicore fibre lasers because it degrades with the increasing number of cores. The beam quality factor of the manufactured multicore fibres equals: 7-core hexagonal structure fibre (BQF = 0.71, V = 2.4), 5-core (BQF = 0.70, V = 2.4), 30-core circular structure of core optical fibre laser possesses the lowest beam quality factor (BQF = 0.48, V = 2.4). However, the angular divergence of the central peak is reduced in proportion to the number of cores generating mutually coherent radiation. Numerical simulation shows that standard deviation of the phase error below 15° has an inconsiderable impact on the laser beam quality. The luminescence spectra of the fabricated constructions: 5-core, 7-core and 30-core double clad multicore optical fibres doped with $Nd^{3+}$ were measured.
