Streszczenie
Obecnie dolegliwości bólowe kręgosłupa lędźwiowo-krzyżowego stanowią istotny problem zdrowotny, społeczny i ekonomiczny. Celem pracy była ocena dolegliwości bólowych dolnego odcinka kręgosłupa i nawyków ruchowych u osób prowadzących siedzący tryb życia, wynikający z charakteru wykonywanej pracy zawodowej.
Badania przeprowadzono w okresie od listopada 2010 do lutego 2011. Materiał badawczy stanowiły 2 grupy osób: 57 pracowników biurowych (w tym 40 kobiet i 17 mężczyzn) oraz 43 kierowców autobusów i taksówkarzy (wyłącznie mężczyźni). W pierwszej grupie prze- dział wiekowy mieścił się w granicach od 21 do 60 lat, a w drugiej między 21, a 63 lat. Narzędzie badawcze stanowiła autorska ankieta składająca się z czterech części. Pierwsza i druga część zawierała pytania dotyczące danych osobowych oraz informacji na temat wykonywanej pracy. W trzeciej zapytano o ewentualne dolegliwości bólowe dolnego odcinka kręgosłupa, natomiast w czwartej o nawyki ruchowe, znajomość profilaktyki i sposób spędzania czasu wolnego.
Uzyskane wyniki świadczą o częstszym występowaniu dolegliwości bólowych dolnego odcinka kręgosłupa wśród kierowców (62,8%). Problem ten dotyczy również częściej osób z wysokim nieprawidłowym BMI (25 i powyżej). Więcej nieprawidłowości w postawie ciała pojawiało się w grupie pracowników biurowych niż wśród kierowców.

Neuroplasticity in rehabilitation after central nervous system damages – computational models
Authors: Mikołajewska Emilia , Mikołajewski Dariusz 
Published: September 2013

AbstractIncreasing survival rates in severe illnesses and traumatic injuries can lead to an increase in the number of disabled people with central nervous system (CNS) damages. Motor training after CNS damage is an important part of neurorehabilitation. It can partially reverse the loss of cortical representation after lesion thanks to neuroplasticity. Patients may regain some motor functions in the months following damage due both to spontaneous recovery and physical therapy interventions targeted at further improvement of function. The neural correlates of motor training after CNS damage have been investigated in animals with motor cortex lesions and in humans using fMRI, TMS, etc. However it is hard to fully explain all mechanisms of neuroplasticity. One of ways to increase knowledge and clinical experience is developing of computational models. To refine a lot of hypotheses existing in the area of CNS neuroplasticity there are useful computational models of lesions and following recovery due to neurorehabilitation. The models based on artificial neural networks are novel solution, but in some cases can provide effectivity and biological plausibility.This article aims at investigating the extent to which the available opportunities are being exploited, including models as a first step in the development of adaptive and cost-effective rehabilitation methods tailored to individuals with CNS deficits.
Rehabilitation protocol of „runner’s knee” (Iliotibial Band Syndrome - ITBS) – a case study
Authors: Biernat Ryszard , Czaprowski Dariusz 
Published: September 2013

AbstractIntroduction:„Runner’s knee”, in other words Iliotibial Band Syndrome (ITBS) is the second, after PFPS, in terms of incidence frequency overuse injury amongst runners - 8.5 %. It is the most common cause of lateral knee pain. It mainly occurs in middle aged athletes, in the second decade of life. Cyclists, skiers, weight lifters, soccer and tennis players are next groups, where this clinical entity occurs. ITBS is typical overuse injury which results from cyclic friction (or compression) of iliotibial band on lateral epicondyle of femur. Training errors are main risk factors. Biomechanical disorders leading to this entity are: weakness of gluteus medius, lack of functional hip mobility, weakness of knee flexors and extensors, shortness of hip adductors, limited hip internal rotation. Improper saddle height, frame size or incorrect pedal position can cause ITBS among cyclists.Case study:Professional cyclist was referred to Rehabilitation Centre, complaining about severe pain located at lateral side of the right knee, lasting from 4 months. The pain was described as burning, sharp, increasing during biking, finally disabling him to continue sports activity. After biomechanical analysis we introduced functional re-education training correcting disbalances, the causes of injury. The role of tri-planar, eccentric exercises rotating the pelvis is underlined. After 7 weeks of aggressive, functional rehabilitation resumed sports activity without pain and functional limitations.Conclusions:An early diagnosis of ITBS allows for shorter rehabilitation time. It’s necessary to precisely determine biomechanical disorders leading to ITBS. 7-week rehabilitation, with functional, three dimensional exercises is effective mean of ITBS treatment. We recommend to continue this kind of exercises for 6-12 months to prevent injury recurrence
The automorphism groups of foliations with transverse linear connection
Authors: Zhukova Nina , Dolgonosova Anna 
Published: September 2013

AbstractThe category of foliations is considered. In this category morphisms are differentiable maps sending leaves of one foliation into leaves of the other foliation. We prove that the automorphism group of a foliation with transverse linear connection is an infinite-dimensional Lie group modeled on LF-spaces. This result extends the corresponding result of Macias-Virgós and Sanmartín Carbón for Riemannian foliations. In particular, our result is valid for Lorentzian and pseudo-Riemannian foliations.

Abstract
BAYANAL code in geotechnical design based on Eurocode 7. Geotechnical problems that are characterized by a high degree of complexity and uncertainty with respect to the input data are solved recently, using the Bayesian analysis (for instance the problem of a cautious estimation of the geotechnical characteristic parameters according to the Eurocode 7 requirements). The applicability of the Bayesian approach to geotechnics via a simple examples related to determination of characteristic values of geotechnical parameters for design structures is in the paper addressed. In order to select the characteristic parameters for the geotechnical design a new numerical code called BAYANAL was developed. Example of applying the BAYANAL code to analyse the DMT tests demonstrates that it is a powerful and promising tool in evaluation of ground properties and geotechnical parameters.

Published: September 2013

AbstractObjective:To search the English language literature for original research addressing the effect of cryotherapy on motor performance and recovery.Data Sources:We searched MEDLINE, the Physiotherapy Evidence Database, SPORT Discus, Pubmed, and the Cochrane Reviews database, from 1976 to 2009 to identify randomized clinical trials of cryotherapy, systematic reviews, original articles and methods of cryotherapy. Key words used were cryotherapy, return to participation, cold treatment, ice, injury.Data Synthesis:Brief review including assessment of cryotherapy as a tool of performance and a recovery method.Conclusions:Most studies suggest that a short rewarming time would be beneficial (a couple minutes), which is very reasonable in sports. Also, cooling techniques differ in its result accordingly to the procedures and objectives used. Finally, the type of tissue cooled plays a large role (ie. Joint vs. Muscle).

Published: September 2013

The biochemical composition (proteins, lipid, ash and moisture) of different parts of the body (gill, meat, egg) of fattened and natural mud crab Scylla serrata was determined. Twenty four samples of S. serrata (12 from wild & 12 from fattening farm) of different sizes and sexes (half of the sample is male) were used in this study. The mean protein and lipid contents are significantly (p<0.05) higher in fattened crabs than natural in natural crabs regardless of size and sexes. Moisture and ash were higher in natural crab than in fattened ones. The highest and lowest moisture content was noticed in gills and eggs in both natural and fattened crabs. Protein and lipid contents were comparatively higher in eggs than in other body parts. Female crabs contained high protein and lipid than males in both natural and fattened crabs. From the results of this study it may considered that fattened crab might be comparatively superior to natural crabs as they appear to provide higher levels of protein and fat for human nutrition.

Imbalance in Life Table: Effect of Infant Mortality on Lower Life Expectancy at Birth
Authors: Fazle Rabbi A. M. 
Published: September 2013

Life expectancy at birth is a well-known demographic measure of population longevity. Rationally, life expectancy at birth should be higher than life expectancy at any particular age. However, historically, lower life expectancy at birth is observed than that of age one, which diminishes the feature of life expectancy at birth as a prominent indicator of longevity. High infant and child mortality rates result in lower values of life expectancy at birth than at older ages. This imbalance in life table disappears only when the crossover occurs and it happens when the inverse of the infant mortality becomes equal to the life expectancy at age one. For Matlab Health and Demographic surveillance system of Bangladesh, life expectancy at age one is still higher than life expectancy at birth. Required infant mortality rate to achieve crossover suggests further decline in infant mortality for Matlab HDSS to attain crossover of life expectancy at birth and age one.

Authors: Rasmi Y. , Seyed-Mohammadzad M. H. , Raeisi S. 
Published: September 2013

Cytotoxin-associated gene A (CagA) may induce a persistent systemic inflammatory response in cardiac syndrome X (CSX). We aimed to evaluate relationship of CagA status and high sensitivity C-reactive protein (hs-CRP) in CSX patients. Sixty CSX patients and 60 gender matched controls were enrolled. Plasma samples were tested in terms of the presence of IgG antibody to Helicobacterpylori (anti-H. pylori) and CagA (anti-CagA) using ELISA method. Also, plasma level of hs-CRP was measured by ELISA method. CSX patients were detected to have significantly higher plasma hs-CRP level in comparison with the control ones (3.64 ± 3.07 vs. 0.54 ± 0.49, µg/ml, P = 0.0001). Plasma levels of hs-CRP in CSX patients with anti-CagA+ were significantly higher than those in anti-CagA(-) (CSX: 4.66±3.63 vs. 2.58±1.95 µg/ml, P = 0.011). Also, plasma levels of hs-CRP in the controls with anti-CagA+ were significantly higher than those in anti-CagA- (1.05±0.68 vs. 0.32±0.31 µg/ml, respectively, P = 0.004). The present data suggested that CagA status was probably associated with susceptibility to severe CSX by causing inflammation. The evidence for this hypothesis indicated that levels of hs-CRP increased in anti-CagA+ patients compared to the anti-CagA- ones.

Authors: Uzma G 
Published: September 2013

Mixed Ni-Zn ferrites (x = 0.66, 0.77, 0.88, 0.99) were prepared by the double sintering ceramic method. Locally available low cost Fe2O3 with 0.5wt% of Si additive was used for this purpose to reduce the process price markedly and to improve the properties of the ferrite produced. Micro structural and micro hardness properties along with density and porosity have been investigated. Hardness increases with increase in metal contact, x of NixZn1-xFe2O4. SEM and optical micrograph shows very similar morphology of the particles with the amount of Si (0.5 wt %), must be low enough to prevent growth of large grains. © 2013 JSR Publications.

A vertex v is a boundary vertex of a vertex u if for all The boundary graph B(G) based on a connected graph G is a simple graph which has the vertex set as in G. Two vertices u and v are adjacent in B(G) if either u is a boundary of v or v is a boundary of u. If G is disconnected, then each vertex in a component is adjacent to all other vertices in the other components and is adjacent to all of its boundary vertices within the component. Given a positive integer m, the mth iterated boundary graph of G is defined as A graph G is periodic if for some m. A graph G is said to be an eventually periodic graph if there exist positive integers m and k >0 such that We give the necessary and sufficient condition for a graph to be eventually periodic.

Published: September 2013

The study measures the relationship between physico-chemical variables with the cell density of phytoplankton in nursery, growout and broodstock ponds of fish. This study was conducted at Natore Government Fish Farm in Bangladesh from January to June, 2012. The observed physico-chemical variables like water temperature, transparency, dissolved oxygen, pH, ammonia-nitrogen, total alkalinity and total hardness were found within the standard ranges. Phytoplankton belonging to bacillariophyceae, chlorophyceae, cyanophyceae and euglenophyceae were found among the ponds but euglenophyceae with highest abundance was recorded in almost all the ponds. Total abundance of different groups of phytoplankton was recorded as mean (±SD) cell density (cell/l) (62.77±2.16)×104, (47.22±0.69)×104, and (77.12±3.42)×104 in nursery pond, growout pond and broodstock pond, respectively. Overall phytoplankton abundance was more in broodstock pond than in others. Total phytoplankton density has exhibited significantly positive correlation with dissolved oxygen (DO) and inverse relation with water temperature, pH, ammonia-nitrogen and total alkalinity in case of nursery pond. For growout pond, total phytoplankton density has exhibited significantly positive correlation with temperature and transparency, and significantly negative correlation with other physico-chemical characteristics. In case of broodstock pond, total phytoplankton density has no significant relationship with any physico-chemical variables of water.

Petrology of Exposed Basement Rocks around Shintaku of North Central Nigeria
Authors: Odedede O. 
Published: September 2013

The study area is part of the Basement Complex of North Central Nigeria. The study aims at identifying the rock types and interpretation of the structural elements. The major rock units in the area comprises of porphyritic granite, gneiss and schist. Structural evidence shows that the rocks are deformed and where intruded by the granite. Petrographic analysis reveals the existence of feldspar phenocrysts in a groundmass of quartz and biotite. The granite is composed of quartz (25-35%), plagioclase (15-20%), orthoclase (10-20%), microcline (5-25%), biotite (15-20%) and other accessory minerals. The granites displayed a porphyritic texture while the schist and gneisses exhibit planar and linear structures. Variation in structural trend and mineralogical composition is due to the series of deformational activities which has affected the rocks during geologic time.

Published: September 2013

A number of furanose (2,4) and pyranose (5,7,9,11,13) acetates were prepared by direct acetylation method. For comparative antimicrobial studies sucrose octaacetate (14) was also prepared. All the compounds (1-14) were screened for in vitro antibacterial activity against ten human pathogenic bacteria viz. Bacillus subtilis, Bacillus cereus, Bacillus megaterium, Staphylococcus aureus, Escherichia coli, INABA ET (Vibrio), Pseudomonas species, Salmonella paratyphi, Salmonella typhi and Shigella dysenteriae. These compounds were also screened for in vitro antifungal activity against four pathogenic fungi viz. Aspergillus niger, Alternaria alternata, Curvularia lunata and Fusarium equiseti. The study revealed that the pyranose acetate derivatives (5,7,9,11,13) are more prone towards antimicrobial functionality than those of the furanose acetates (2,4) and sucrose octaacetate (14).

Published: September 2013

Objective.In patients with systemic sclerosis (SSc), sexual function is somewhat impaired. Our aim was to evaluate sexual function in women with SSc in comparison to controls, and to investigate the association with sociodemographic and disease characteristics, and physical and psychological variables.Methods.Forty-six women with SSc and 46 healthy women were assessed for sociodemographic characteristics and gynecological development and administered the Female Sexual Function Index (FSFI), Medical Outcomes Study Short Form-36 (SF-36), Health Assessment Questionnaire (HAQ), Hospital Anxiety and Depression Scale (HADS), Rosenberg Self-Esteem Scale, Coping Orientation to Problems Experienced-New Italian Version, and Functional Assessment of Chronic Illness Therapy-Fatigue Scale. Patients were also assessed for disease duration and subset, Female Sexual Function in SSc, Hand Mobility in Scleroderma test (HAMIS), Cochin Hand Functional Disability Scale, Mouth Handicap in Systemic Sclerosis Scale (MHISS), Disability Sexual and Body Esteem Scale (PDSBE); and fist closure, hand opening, and mouth opening.Results.In patients with SSc, only FSFI desire subscale score was significantly lower (p = 0.035) versus controls. Total FSFI score, similar to controls, was related with Medical Outcomes Study Short Form-36 mental component, HAQ (p = 0.022), MHISS (p = 0.038), and HAMIS (p = 0.037). In SSc, the main factors independently associated with sexual functioning were vaginal dryness [regression coefficient (B) = −0.72; p < 0.001], PDSBE (B = 0.42; p = 0.001), and HADS depression scale (B = −0.23; p = 0.035). Together, these variables explained 70% of the variance in the FSFI total score.Conclusion.In SSc, sexual function, although not different from controls, is influenced by specific disease-related and psychological concerns. Thus it should be included in patient evaluations and assessed in daily clinical practice.
