Abstract
The paper analyzes the imaging properties of the light sword optical element (LSOE) applied as a contact lens to the presbyopic human eye. We performed our studies with a human eye model based on the Gullstrand parameterization. In order to quantify the discussion concerning imaging with extended depth of focus, we introduced quantitative parameters characterizing output images of optotypes obtained in numerical simulations. The quality of the images formed by the LSOE were compared with those created by a presbyopic human eye, reading glasses and a quartic inverse axicon. Then we complemented the numerical results by an experiment where a 3D scene was imaged by means of the refractive LSOE correcting an artificial eye based on the Gullstrand model. According to performed simulations and experiments the LSOE exhibits abilities for presbyopia correction in a wide range of functional vision distances.

Abstract
We present results of numerical analysis of the Strehl ratio characteristics for the light sword optical element (LSOE). For comparison there were analyzed other optical imaging elements proposed for compensation of presbyopia such as the bifocal lens, the trifocal lens, the stenopeic contact lens, and elements with extended depth of focus (EDOF), such as the logarithmic and quartic axicons. The simulations were based on a human eye's model being a simplified version of the Gullstrand model. The results obtained allow to state that the LSOE exhibits much more uniform characteristics of the Strehl ratio comparing with other known hitherto elements and therefore it could be a promising aid to compensate for the insufficient accommodation range of the human eye.

Abstract
Objective Chronic obstructive pulmonary disease (COPD) is characterized by irreversible progressive airflow limitation related to tobacco smoking. This limitation is caused by chronic inflammation of the airways and lung parenchyma and is associated with increased activity of parasympathetic system. The most effective bronchodilators in COPD are muscarinic receptor antagonists (MRA), which reverse, at least in part, compromised respiratory function. MRA also contribute to control inflammatory processes via interactions with inflammatory signaling molecules. The use of the long-acting cholinolytic bronchodilatator - tiotropium, with high affinity to M3 receptors, is suggested as a first line maintenance treatment in COPD patients. Materials and methods In this study we assessed M3 receptor protein expression in induced sputum of 27 stable COPD patients before and after therapy consisting of 18 μg once daily tiotropium for 12 weeks. Lung function tests including spirometry, lung volumes, and DLCO were performed before and after therapy in all COPD patients. The patients were subjected to the sputum induction procedures before and after therapy. Sputum cells were isolated, sample-specific cell profiles were characterized, and the cells were processed to isolate pure cytosolic fractions. Cytosolic M3 protein and HDAC2 levels and nuclear acetylated histone H3 (AcH3) expression was quantified using specific antibodies against human proteins and Western blot with enhanced luminescence detection. Results Therapy significantly increased the mean forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) volume (P < 0.05). The mean expression of M3 protein was higher by 37% after therapy (P < 0.05), HDAC2 expression was not altered, while AcH3 level was increased by about 90% (P < 0.01), compared with the corresponding data before therapy. HDAC2 expression before therapy was positively correlated with AcH3 expression (r = 0.74), while after therapy no correlation was detected. FEV1, FCV, and cytosolic M3 protein expression did not correlate with other biochemical parameters tested. Conclusions Twelve weeks of tiotropium therapy in COPD patients improves clinical indices of lung function and involves alterations in sputum cell chromatin acetylation and also increased cholinergic M3 receptor internalization.

Abstract
Objective Immunophilin FKBP51 assists polypeptide folding, participates in glucocorticoid actions and may play a role in glucocorticoid resistance. FKBP51 is altered in patients with asthma, but its role in chronic obstructive pulmonary disease (COPD) characterized by dysregulation of several pro/antiinflammatory genes is less clear. Methods We assessed changes in nuclear/cytosolic FKBP51 protein using SDS-PAGE/WB and FKBP51 mRNA by qRT-PCR in cells isolated from induced sputum of stable COPD patients treated with formoterol/budesonide or formoterol/budesonide/theophylline for 4 wk. Results Expression of FKBP51 was higher in formoterol/budesonide/theophylline-treated patients, compared with formoterol/budesonide group in both cytosolic and nuclear fractions by about 57% and 31%, respectively (P < 0.001, P < 0.01). FKBP51 mRNA was only slightly, but not significantly, higher in patients on formoterol/budesonide/theophylline. Conclusions Increased FKBP51 in COPD patients treated with formoterol/budesonide/theophylline may be important in altering signaling from corticosteroid receptors.

Abstract
Propofol can be potentially beneficial in oxidative stress related malignancies as neurodegenerative diseases and traumatic brain injury but its signalling pathways are poorly understood. In this study effect of propofol on astroglial signalling in oxidative stress was evaluated. Ten days old cultures of rat astroglial cells were treated for 1 hour with t-butyl hydroperoxide (tBHP) to induce oxidative stress following by 1 hour propofol. We measured cytotoxicity, changes in cell growth and apoptosis as well as alterations in expression and acetylation of chromatin core H3 and H4 histone proteins and changes in native and phosphorylated cAMP-response-element-binding protein (CREB). tBHP induced limited cytotoxicity, increased apoptosis, decreased glutamine synthetase and enolase activities, decreased nuclear CREB, CREB-P and histone proteins but unchanged cytosolic CREB and histone acetyltransferase (HDAC) expression. Propofol clearly protected the cells against tBPH-induced toxicity, normalized alterations in cell growth, restored to some extent glial enzyme activities and reduced apoptotic cell numbers. Also, propofol restored H3 but not H4 expression/activation, but was without effect on decreased nuclear CREB expression/activation. These data show that oxidative stress in cultured astroglia significantly affects nuclear CREB and histone proteins and point to the protective role of propofol.

Abstract
The paper presents first experiments with a refractive light sword optical element (LSOE). A refractive version of the LSOE was prepared in photoresist by gray scale photolithography. Then we examined chromatic aberrations of the produced element and compared them with those corresponding to two different lenses. For this purpose we performed two experiments, the first one where white light illumination was used and the latter one by the help of monochromatic illumination with three different wavelengths. The obtained results lead to the conclusion that the refractive LSOE does not exhibit significant chromatic aberrations and can be successfully used for imaging with extended depth of focus in polychromatic illumination.

Abstract
The paper presents imaging properties of modified lenses with the radial and the angular modulation. We analyze three following optical elements with moderate numerical apertures: the forward logarithmic axicon and the axilens representing the radial modulation as well as the light sword optical element being a counterpart of the axilens with the angular modulation. The abilities of the elements for imaging with extended depth of focus are discussed in detail with the help of structures of output images and modulation transfer functions corresponding to them. According to the obtained results only the angular modulation of the lens makes possible to maintain the acceptable resolution, contrast and brightness of the output images for a wide range of defocusing. Therefore optical elements with angular modulations and moderate numerical apertures seem to be especially suitable for imaging with extended focal depth.

Abstract
Initial results are reported of a Polish-Finnish project to verify electron dose distributions calculated by treatment planning systems (TPSs), CadPlan v.6.3.2 and Theraplan v.3.5, which use different electron beam dose distribution algorithms. Treatment of gross tumour volumes representing lung and parotid cancer was simulated in an Alderson anthropomorphic phantom with thermoluminescent detectors (TLDs) (Li(2)B(4)O(7):Mn,Si) placed at selected measurement points inside its volume. The observed discrepancy between relative values of dose calculated and measured by TLDs at each of the measurement points and those calculated by the different TPSs at the same points is discussed.

Abstract
A new theoretical model of the Lau effect is presented. The transmittance of a diffraction grating can be expressed in an equivalent form as the sum of transmittances of thin cylindrical lenses. Therefore it is possible to explain the Lau effect on the basis of the well-known imaging properties of lenses. According to the given approach, the Lau fringes are created by overlapped images of the first grating that are formed by a set of lenses corresponding to the second grating in the setup. The theory leads to an exhaustive description of the Lau-effect parameters. In particular, one can indicate the shape of the Lau fringes and localize planes of the fringes dependent on the axial distance between gratings and their periods.

Abstract
The characteristic dimensions of Bessel beams are fully determined by the corresponding Bessel functions. We consider a way of obtaining a narrower diameter of the central core of a diffractive pattern generated by the Bessel beams. The method relies on superposition of two or more Bessel beams with appropriately chosen amplitudes and widths. The disturbing influence of the aperture's edges can be eliminated by addition of the proper amplitude filter.

Our approach enables one to define the limit of resolution of the object reconstruction and the light-intensity distribution in an output plane. The analysis takes into account a hologram aperture, a sampling aperture, and a curvature radius of spherical illumination. Theoretical results are confirmed by experimental verification.

Abstract
We show that the apodized annular-aperture logarithmic axicon preserves excellent uniformity of the on-axis intensity, energy flow, and lateral resolution. Numerical evaluation of the Fresnel diffraction integral leads to results very close to geometrical-optics predictions. Once again the geometrical law of energy conservation turns out to be a useful tool in designing axicons.

Abstract
The generation of diffractive elements of variable optical parameters and high diffraction efficiency is presented. It can be realized by a superposition of two conjugate kinoforms. In particular, the method gives rise to zone plates of variable focusing power as well as to circular and linear gratings of variable deflection angles. The theoretical description is illustrated by an experimental example of the blazed grating with a changeable period; some possible applications are mentioned.

The simple formula derived in the paper establishes a direct relationship between moire beat patterns and basic grids for minute displacements. The possibilities of finding a basic grid for a desired moire pattern are pointed out. The analysis is illustrated by several examples of Fresnel moire zone plate patterns and concentric equidistant circular moire patterns obtained by changes of scale and rotation. Possible advantages of the practical use of this element are outlined.

We report the solid-phase synthesis of 21 linear analogues of A and D, two nonselective antagonists of the vasopressor (V1) and antidiuretic (V2) responses to arginine vasopressin (AVP). A is Aaa-D-Tyr(Et)-Phe-Val-Asn-Abu-Pro-Arg-Arg-NH2 (where Aaa = adamantylacetyl at position 1). D is the des-Arg9 analogue of A. Nine new analogues of A (1-9) and 12 new analogues of D (10-21) were obtained. The following substitutions either alone or in combination were incorporated in A and/or in D: phenylacetic acid (Phaa) and tert-butylacetic acid (t-Baa) at position 1; D-Tyr2, D-Tyr(Me)2; Gln4; Arg6, Lys6, Orn6, MeAla7. The nine new analogues of A are (1) [Arg6], (2) [Lys6], (3) [Orn6], (4) [Phaa1,Lys6], (5) [Phaa1,Orn6], (6) [D-Tyr2], (7) [D-Tyr2,Arg6], (8) [Phaa1,D-Tyr2], (9) [Phaa1,D-Tyr2,Arg6]. The 12 new analogues of D are (10) [Arg6], (11) [Lys6], (12) [Orn6], (13) [Phaa1,Lys6], (14) [Phaa1,Gln4,Lys6], (15) [Phaa,D-Tyr(Me)2,Lys6], (16) [Phaa,D-Tyr(Me)2,Gln4,Lys6], (17) [Phaa1,D-Tyr2,Gln4,Lys6], (18) [t-Baa1,Lys6], (19) [t-Baa1,Gln4,Lys6], (20) [Arg6,MeAla7], (21) [t-Baa1,Arg6,MeAla7]. All 21 peptides were examined for agonistic and antagonistic potencies in AVP V2 and V1 assays in rats. With the exception of 6, the eight remaining new analogues of A are equipotent or more potent than A as V1 antagonists. Peptides 2-9 are less potent than A as V2 antagonists. Three, 4, 5, and 9, exhibit significant gains in anti-V1/anti-V2 selectivities (selectivity ratio = 41, 14, and infinite, respectively), compared to A (anti-V1, pA2 = 7.75 +/- 0.07; selectivity ratio = 0.44). Peptide 9 is unique in both series. It is a highly potent V1 antagonist (anti-V1 pA2 = 8.62 +/- 0.11 and is the first linear peptide to exhibit substantial antidiuretic agonism (4.1 +/- 0.2 units/mg). With the exception of 12, the remaining 11 analogues of D are 8-40 times more potent than D as V1 antagonists. Eight of these peptides exhibit significant gains in anti-V1/anti-V2 selectivities compared to D (anti-V1 pA2 = 7.43 +/- 0.06; selectivity ratio = 1.6).(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
We report the solid-phase synthesis of 12 desGly and 12 desGly(NH2) analogues of arginine-vasopressin (AVP), two highly selective antidiuretic (V2) agonists, four vasopressor (V1) antagonists, and five V2/V1 antagonists. The parent AVP agonists are (1) AVP, (2) 1-deamino[8-D-arginine]vasopressin (dDAVP), and (3) its 4-valine analogue, dVDAVP. The parent V1 antagonists are (4) [1-(beta-mercapto-beta,beta-pentamethylenepropionic acid)] arginine-vasopressin (d(CH2)5AVP), (5) d(CH2)5VDAVP, (6) [1-deaminopenicillamine,4-valine,8-D-arginine]vasopressin (dPVDAVP), and (7) d(CH2)5[Tyr(Me)]AVP. The parent V2/V1 antagonists are (8) d(CH2)5[D-Phe2,Ile4]AVP, (9) d(CH2)5[D-Phe2]VAVP, (10) d(CH2)5[D-Tyr(Et)2]VAVP, (11) d(CH2)5[Tyr(Et2]VAVP, and (12) d(CH2)5[D-Ile2,Ile4]AVP. All 24 analogues were tested for agonistic and antagonistic activities in in vivo rat vasopressor and rat antidiuretic assays. The desGly and desGly(NH2) analogues of 1-3 are either weak partial agonists or weak antagonists of the V1 responses to AVP. Except for desGly(NH2)AVP, which is a weak V2 agonist, the remaining desGly and desGly(NH2) analogues of 1-3 exhibit substantial V2 agonism and are thus highly selective V2 agonists. With antidiuretic activity of 321 units/mg, a resynthesized desGly(NH2)dVDAVP is equipotent with AVP as a V2 agonist. Thus our previously stated conclusion about the need for C-terminal CONH2 for V2 agonism is no longer valid. The four pairs of desGly/desGly(NH2) analogues of the V1 antagonists (4-7) all retained varying degrees of V1 antagonism and some exhibited striking enhancements in anti-V1/V2 selectivity. Thus the desGly/desGly(NH2) analogues of d(CH2)5Tyr(Me)AVP are highly potent V1 antagonists/weak V2 antagonists with anti-V1/V2 selectivities of 200 and 1200, respectively. The four pairs of desGly/desGly(NH2) analogues of the V2/V1 antagonists (8-11) exhibited enhancements, full retention, or slight diminishment of both V1 and V2 antagonism, with the desGly analogue being usually the more potent of each pair. The desGly and desGly(NH2) analogues of d(CH2)5[D-Ile2,Ile4]AVP (12) exhibited anti-V2/V1 selectivities of 46 and about 440, respectively. These are the most selective V2 antagonists reported to date. Many of these analogues could serve as useful pharmacological tools in studies on the roles of AVP in normal and pathophysiological circumstances.

Abstract
Vasopressin antagonists are valuable pharmacological tools for investigating physiological and behavioural functions of the nonapeptide arginine-vasopressin (AVP). The removal of glycinamide from the carboxy terminus of AVP drastically reduces its characteristic vasopressor and antidiuretic activities. In contrast to this we show here that removal of the carboxy-terminal glycinamide or the glycine at position 9 from several vasopressin antagonists makes little difference to their ability to block vasopressor and antidiuretic responses to AVP. These data demonstrate the critical structural requirements of the carboxy-terminal position for receptor activation, in contrast to the lack of such requirements for receptor binding. They also provide an avenue to a wide variety of antagonists substituted at the carboxy terminus (for example radiolabelled derivatives and affinity ligands) and suggest clues for the development of more potent and/or selective antagonists.
