Abstract
BACKGROUND The supraspinatus muscle, one of the four rotator cuff muscles, initiates abduction of the arm, simultaneously stretching the articular capsule at the glenohumeral joint, and also contributes to exorotation of the arm. In the present study we aimed to evaluate the age-specific normative values for morphometric parameters of the supraspinatus muscle in human fetuses at varying ages and to elaborate their growth models. MATERIALS AND METHODS Using anatomical dissection, digital image analysis (NIS Elements AR 3.0) and statistics (Student's t-test, regression analysis), the length, width, circumference and projection surface area of the supraspinatus muscle were measured in 34 human fetuses of both sexes (16 males, 18 females) aged 18-30 weeks of gestation. RESULTS Neither sex nor laterality differences were found in numerical data of the supraspinatus muscle. In the supraspinatus muscle its length and projection surface area increased logarithmically, while its width and circumference grew proportionately to gestational age. The following growth models of the supraspinatus muscle were established: y = -71.382 + 30.972 × ln(Age) ± 0.565 for length, y = -2.988 + 0.386 × Age ± 0.168 for greatest width (perpendicular to superior angle of scapula), y = -1.899 + 0.240 × Age ± 0.078 for width perpendicular to the scapular notch, y = -19.7016 + 3.381 × Age ± 2.036 for circumference, and y = -721.769 + 266.141 × ln(Age) ± 6.170 for projection surface area. CONCLUSIONS The supraspinatus muscle reveals neither sex nor laterality differences in its size. The supraspinatus muscle grows logarithmically with reference to its length and projection surface area, and proportionately with respect to its width and circumference.

Abstract
The kinetics and dynamics of the stiff and flexible tines with the duckfoot and the coulter after impact with stones embedded in compacted soil were examined. The beak of the duckfoot was positioned in the axis of the row of stones embedded in the soil at the depth of stones thickness. The coulter covered the stone or impact the edge of the stone halfway along its length. The tools worked at a speed of 0.83–2.22 m·s−1 and a working depth of 0.05–0.10 m. The results of specific parameters were compared to the response of the tools to loads in soil without stones. For both soil conditions, the kinetics of the flexible tine was 24 times more reactive, and the dynamic loads were two times lower than for the stiff tine. The responses of both tines were suppressed along with the working depth because of the more favorable place of impact of the duckfoot beak with the stone. Along with the working speed, for a stiff tine, the specific accelerations decreased significantly, by ten times, and the specific forces increased slightly, by 1.6 times. Among the two systems of setting the coulter, the impact of the cutting edge of the coulter with the stone in the middle of its length was more unfavorable than the work of the coulter covering the stone.

Abstract
Lignocellulose is an abundant substrate for biogas production; however, for efficient utilization, proper pre-treatment is required to enhance the biomethane yield and hydrolysis rate significantly. Phenolic compounds from dissolved lignin, produced during alkali pre-treatment, have inhibitory effects on the anaerobic digestion; however, the possible inhibitory effects of solid lignin have not gathered enough interest. Especially, the effect of solid lignin on methanogenesis remains a knowledge gap. In this study, kraft lignin was used as a model solid lignin substrate for its co-digestion with microcrystalline cellulose. A new approach of modelling biomethane production curves using smoothing splines was developed to describe the long-term inhibitory effects of solid lignin on hydrolysis and methanogenesis. The method gives possibility to describe long-term inhibitory effects by using batch instead of continuous test data. Results revealed that kraft lignin showed mild inhibitory effects on methanogens. However lignin impact combined with volatile fatty accumulation can prolong hydrolysis and reactor recovery start-up by 47.3% and 75.3%, respectively. For small dosages of solid lignin adaptation of methanogens is possible.

Abstract
The aim of this study was to investigate the pressure agglomeration process of wheat straw (WS) and the blends of WS with calcium carbonate (CC) or cassava straw (CS) with a ratio of 6% wt./wt. from seven separate fractions with sizes in the range of 0.21-2.81 mm. The agglomeration was performed at a moisture of 30% wb and a material temperature of 78 °C, with a dose of 0.1 g, in a die of diameter 8 mm and height 80 mm. The effects of the process were evaluated based on the compaction parameters and the pellets' density, tensile strength, and water absorption. The incorporation of additives into the WS improved the pellet process and quality. Refined results were achieved after adding CC, as compared to those achieved after adding CS, and the preferred particle size was in the range of 1.00-1.94 mm. This was because, under the given conditions, the back pressure in the die chamber significantly increased, allowing the achievement of a single pellet density of 800 kg·m-3. The pellets were resistant to compressive loads and cracked only at tensile strength of 6 MPa and a specific compression work of 6.5 mJ·mm-2. The addition of CC to the WS improved the strength of the adhesive and the cohesive bonds between the particles. The water absorption for the uncrushed pellets was considerably less than that for crushed pellets, which results in the safer storage of uncrushed pellets and excellent moisture absorption of crushed pellets. The addition of CC to the WS offers benefits in the form of pellet strength with a high water absorption capability. Notably, a study of crushed pellet litter under broiler rearing conditions and an analysis of the operational costs of using WS additives are required for implementing this study.

Abstract
Abstract
Aims
The aim of this study was to determine the relationship between electrical and mechanical activation in heart failure (HF) patients and whether electromechanical coupling is affected by scar.
Methods and results
Seventy HF patients referred for cardiac resynchronization therapy or biological therapy underwent endocardial anatomo-electromechanical mapping (AEMM) and delayed-enhancement magnetic resonance (CMR) scans. Area strain and activation times were derived from AEMM data, allowing to correlate mechanical and electrical activation in time and space with unprecedented accuracy. Special attention was paid to the effect of presence of CMR-evidenced scar. Patients were divided into a scar (n = 43) and a non-scar group (n–27). Correlation between time of electrical and mechanical activation was stronger in the non-scar compared to the scar group [R = 0.84 (0.72–0.89) vs. 0.74 (0.52–0.88), respectively; P = 0.01]. The overlap between latest electrical and mechanical activation areas was larger in the absence than in presence of scar [72% (54–81) vs. 56% (36–73), respectively; P = 0.02], with smaller distance between the centroids of the two regions [10.7 (4.9–17.4) vs. 20.3 (6.9–29.4) % of left ventricular radius, P = 0.02].
Conclusion
Scar decreases the association between electrical and mechanical activation, even when scar is remote from late activated regions.

Abstract
BACKGROUND Evaluation of skin condition on the basis of parametrization and objective measurements of the parameters has become obligatory. The aim of this study was to assess sex-related changes in skin topography and structure using the skin testing equipment. MATERIALS AND METHODS The study was carried out on the group of 40 volunteers (20 females and 20 males) of the mean age 24 ± 3 years. The skin parameters were measured using 3 devices: Visioscan® VC 98 (skin topography), Visioline® VL 650 (skin macro relief) and Ultrascan UC22 (ultrasound imaging of the skin). All measurements were performed on the inner part of the left forearm. RESULTS The skin parameters measured revealed significant differences in skin surface and structure between females and males. The skin of all women subjects was more homogenous in its structure with the presence of more abundant superficial skin lines and wrinkles in comparison to male skin. The higher number of skin furrows in the skin of women is in agreement with literature reports claiming that men's skin has lower number of wrinkles which are deeper and more pronounced. Ultrasound imaging of the skin indicated greater thickness and lower density of the dermis of men subjects compared to those of females. CONCLUSION Non-invasive methods of skin testing using new and advanced equipment have provided a possibility of objective parametrization and evaluation of sex-related changes in skin topography and structure.

Abstract
Three crystal structures are presented of nematode thymidylate synthases (TS), including Caenorhabditis elegans (Ce) enzyme without ligands and its ternary complex with dUMP and Raltitrexed, and binary complex of Trichinella spiralis (Ts) enzyme with dUMP. In search of differences potentially relevant for the development of species-specific inhibitors of the nematode enzyme, a comparison was made of the present Ce and Ts enzyme structures, as well as binary complex of Ce enzyme with dUMP, with the corresponding mammalian (human, mouse and rat) enzyme crystal structures. To complement the comparison, tCONCOORD computations were performed to evaluate dynamic behaviors of mammalian and nematode TS structures. Finally, comparative molecular docking combined with molecular dynamics and free energy of binding calculations were carried out to search for ligands showing selective affinity to T. spiralis TS. Despite an overall strong similarity in structure and dynamics of nematode vs mammalian TSs, a pool of ligands demonstrating predictively a strong and selective binding to TsTS has been delimited. These compounds, the E63 family, locate in the dimerization interface of TsTS where they exert species-specific interactions with certain non-conserved residues, including hydrogen bonds with Thr174 and hydrophobic contacts with Phe192, Cys191 and Tyr152. The E63 family of ligands opens the possibility of future development of selective inhibitors of TsTS and effective agents against trichinellosis.

Abstract
Chronic cough is a common medical problem. The aim of the study was to analyze chronic cough causes in non-smoking patients and to search for demographic factors associated with different cough reasons. The etiology of cough was determined by medical history, diagnostic tests and response to specific treatment. Patients with significant abnormalities in the chest radiograph or spirometry were not included. The study included 131 non-smoking patients; median age 54 years, 77 % female. The most frequent causes of cough were gastroesophageal reflux disease (GERD) (62 %) and upper airway cough syndrome (UACS) (46 %). Cough variant asthma and non-asthmatic eosinophilic bronchitis (NAEB) were diagnosed in 32 (25 %) and 19 (15 %) patients, respectively. Other cough causes were found in 27 patients (21 %). Asthma was a significantly more common cause of chronic cough in women than in men (31 % vs. 3 %, p = 0.005). A reverse relationship was demonstrated for UACS (39 % vs. 67 %, p = 0.01). Patients with chronic cough aged >50 yrs were more likely to be diagnosed with less common cough causes. In conclusion, the most common chronic cough reasons are GERD and UACS. Asthma-related cough is diagnosed more frequently in females, while UACS-related cough is more frequent in males.

Abstract
INTRODUCTION In mammals, placenta separation at term may involve degradation of the extracellular matrix by matrix metalloproteinases (MMPs). The activity of MMPs is modulated by TIMPs. We hypothesized that the placentas of mares that deliver fetal membranes physiologically and those that retain fetal membranes (FMR) differ in terms of histology; mRNA expression of MMP-2 and MMP-9; protein expression of MMP-2, MMP-9, and TIMP-2; and the potential activity of both MMPs. METHODS Placenta biopsies were taken from mares (n = 9; 4 FMR, 5 controls) immediately after foal expulsion. Retention was defined as failure to expel all fetal membranes within 3 h of expulsion. All mares were monitored for time of expulsion. The degree of allantochorial/endometrial adhesion was determined in FMR mares, and biopsies from all mares were histologically examined. mRNA expression, protein immunolocalization, protein amount and potential enzyme activity were determined with RT-PCR, immunohistochemistry, Western Blotting and zymography, respectively. RESULTS FMR mares had strong to extremely strong allantochorial/endometrial adhesion, and significantly more connective tissue in the allantochorial villi than controls. The range of MMP-2 mRNA expression levels was more than 13 times greater in FMR mares than in controls. Protein content of both MMPs and TIMP-2 differed significantly between groups. The range of potential MMP-2 and MMP-9 activity was larger in FMR mares, and MMP-2 potential activity was 1.4 times higher in controls (P = 0.02). DISCUSSION These results indicate differences in extracellular matrix remodeling in FMR mares and controls, and suggest dysregulation of MMP expression and activation in FMR mares.

Abstract
By seeking new stable boron-containing nucleoside derivatives, potential BNCT boron delivery agents, a novel synthetic approach was tested, aimed at a boron attachment via a single bond to an aliphatic carbon of sp(3) hybridization. The latter allowed successful modification of deoxycytidine in the reaction with 2-(iodomethyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane of the deoxynucleoside amino group. For new compounds, detailed NMR, LDI HRMS (Laser Desorption/Ionization High-Resolution Mass Spectrometry) analyses along with in vivo phosphorylation studies, toxicity assays and DFT modelling are presented.

Abstract
Background Thymidylate synthase is a housekeeping gene, designated ancient due to its role in DNA synthesis and ubiquitous phyletic distribution. The genomic sequences were characterized coding for thymidylate synthase in two species of the genus Trichinella, an encapsulating T. spiralis and a non-encapsulating T. pseudospiralis. Methods Based on the sequence of parasitic nematode Trichinella spiralis thymidylate synthase cDNA, PCR techniques were employed. Results Each of the respective gene structures encompassed 6 exons and 5 introns located in conserved sites. Comparison with the corresponding gene structures of other eukaryotic species revealed lack of common introns that would be shared among selected fungi, nematodes, mammals and plants. The two deduced amino acid sequences were 96% identical. In addition to the thymidylate synthase gene, the intron-less retrocopy, i.e. a processed pseudogene, with sequence identical to the T. spiralis gene coding region, was found to be present within the T. pseudospiralis genome. This pseudogene, instead of the gene, was confirmed by RT-PCR to be expressed in the parasite muscle larvae. Conclusions Intron load, as well as distribution of exon and intron phases in thymidylate synthase genes from various sources, point against the theory of gene assembly by the primordial exon shuffling and support the theory of evolutionary late intron insertion into spliceosomal genes. Thymidylate synthase pseudogene expressed in T. pseudospiralis muscle larvae is designated a retrogene.

Abstract
Abstract
Trichinella spiralis is a parasitic nematode causing trichinellosis, a serious disease, and Caenorhabditis elegans is a free-living nematode, which is used as a model in parasitological studies. High levels of thymidylate synthase (EC 2.1.1.45; ThyA) and certain other enzymes involved in thymidylate biosynthesis were found throughout T. spiralis and C. elegans developmental cycles, including developmentally arrested forms, that is, T. spiralis muscle larva and C. elegans dauer larva. As ThyA activity is characteristic for cells that left the G0 phase of the cell cycle, an exceptional regulation of the cell cycle in nematodes is suggested, manifested by a global cell cycle arrest in developmentally arrested larvae of the two species. ThyA immunolocalization during development of T. spiralis and C. elegans revealed the presence of high enzyme levels not only in the developing embryos, where it was expected, but also in gonad primordia, egg and sperm cells, nerve ring and secretory cells, opening to T. spiralis esophagus and C. elegans pharynx, where it may point to those cell populations remaining cell cycle arrested.

Abstract
Crystal structures were solved of the binary complexes Trichinella spiralis and Caenorhabditis elegans thymidylate synthases with deoxyuridine monophosphate (dUMP), with crystals obtained by the vapor diffusion method in hanging drops. For the T. spiralis thymidylate synthase-dUMP complex, the diffraction data were collected at the BESSY Synchrotron to 1.9 Å resolution. The crystal belongs to the space group P1 with two dimers in the asymmetric unit (ASU). For the C. elegans TS-dUMP complex crystal, the diffraction data were collected at the BESSY Synchrotron to 2.48 Å resolution, and the crystal belongs to the space group P 32 2 1, with two monomers (one dimer) in the ASU. Structural comparisons were made of both structures and each of them with the corresponding mouse thymidylate synthase complex.

Abstract
The autoimmune reaction is recently suspected to play a role in the pathogenesis of chronic obstructive lung disease (COPD). As COPD is a systemic disease, the elements of an autoimmune response in circulatory system is of interest. It has been shown that regulatory T cells are important in the control of autoimmunity. There are some data on a role of adiponectin in the regulation of immune reactions. The objective of this study was to assess the elements of autoimmune reaction in the peripheral blood (PB) of patients with COPD. Twenty-eight patients with mild/moderate COPD and 20 healthy volunteers were investigated. Flow cytometry method with mixtures of monoclonal antibodies anti: CD14/CD45, CD3/CD19, CD4/CD25/CTLA4 and CD8/CD25 were used. Concentration of adiponectin was measured using ELISA method. We observed significantly lower proportion of CD4+/CD25+ as well as CD4+/CD25+ (high) cells in COPD patients than in healthy controls (15.3 versus 17.8% and 0.79 versus 1.54%, respectively, P < 0.05). The proportion of CTLA4+ cells in CD25+ cells and the mean fluorescence of CTLA4 on CD4+ cells were higher in patients than in healthy controls (10.4 versus 4.7%, P < 0.05, 189% versus 149%, non significant, respectively). We found significantly elevated concentration of adiponectin in patients when compared to healthy subjects (15.4 versus 8.5 μl/ml, P < 0.05). We found that the adiponectin/BMI ratio correlated with the decrease of FEV(1) %. The results of this study support the possible role of CD4/CD25/CTLA4 cells and adiponectin in the systemic inflammation in COPD.

Abstract
Thymidylate synthase (TS) of Trichinella spiralis, a parasitic nematode causing trichinellosis, was found to bind its own mRNA and repress translation of the latter, similar to its human counter-part [Chu, Koeller, Casey, Drake, Chabner, Elwood, Zinn and Allegra (1991) Proc. Natl. Acad. Sci. U.S.A. 88, 8977-8981]. However, in striking contrast with human TS, the parasite enzyme's interaction with mRNA was not affected by any of the substrate (deoxyuridylate or N(5,10)-methylenetetrahydrofolate) nor by the inhibitor (fluorodeoxyuridylate; used alone or in the presence of N(5,10)-methylenetetrahydrofolate) similar to that shown for the bifunctional enzyme from Plasmodium falciparum [Zhang and Rathod (2002) Science 296, 545-547]. Moreover, repression of the translation of the parasite enzyme was enhanced by the same ligands that were shown by others (Chu et al., 1991) to prevent human TS from impairing its translation. On comparing the capacity of TS to bind to its cognate mRNA, relative to its ability to inhibit its translation, the same enzyme preparation was active as translational repressor at a considerably lower protein/mRNA ratio, suggesting the two phenomena to be disconnected. Of interest is the fact that the presence of the enzyme protein N-terminal methionine proved to be critical for binding, but not for repression of its translation, indicating that mRNA binding requires a methionine or an adduct (i.e. methionine-histidine) at the N-terminus of TS, but that the translational repression effect does not. Notably, chicken liver dihydrofolate reductase, which is incapable of binding to T. spiralis TS mRNA, repressed the translation of TS.
