Ghana Medical Journal , 2011,
Abstract: Objective: To determine the prevalence of female genital schistosomiasis in riparian communities in the Volta basin of Ghana, Design: The study was a cross-sectional study conducted among women 15-49 years in the Volta Basin. Urinary schistosomiasis prevalence was determined using microscopy. A structured questionnaire was also administered to collect information on the demography, obstetric history and reproductive health experiences. Cervical punch biopsy was collected from women who consented to be screened for FGS. Descriptive statistics was used to determine frequency of occurrence, chi squared and logistic regression to identify associated variables Results: Urinary schistosomiasis prevalence among the women was 24.8% while 10.6% of them diagnosed with FGS. More FGS diagnosed women (57.7%, p value =0.04%) were observed to report copious discharge, vaginal itch (80.8%, p=0.042) and lower abdominal pain (66.7%, p= 0.041) compared to FGS negative women. The predominant abnormal observation of the lower genital tract made was erythematous cervix (18.8%). Conclusion: The study confirms the reproductive health symptoms associated with FGS and recommends awareness creation on FGS among women in endemic communities to facilitate early treatment.

Abstract: Objectives: To investigate Toxoplasma infection among pregnant women in relation to exposure to infection risk, age and pregnancy-related risk factors. Design and Methods: This cross-sectional study involved 294 pregnant women attending ante-natal clinic in Accra who consented to participate. Personal and Toxoplasma infection risk related data were obtained by questionnaire interviews. Venous blood was safely drawn from each participant and spun to obtain sera. Each of the 159 randomly selected serum samples was tested for specific anti-Toxoplasma (anti-T. gondii) antibodies IgG, IgA and IgM using a commercial ELISA kit (Calbiotech Inc., CA). ELISA results were correlated with exposure to possible infection risk factors as well as age and pregnancy-related risk factors. Results: The 159 women aged 15-40 years in their first, second and third trimesters, numbered 29, 70 and 60, respectively. An overall anti-T. gondii antibodies IgG, IgA and IgM seroprevalence of 92.5% (147/159) was recorded, with 4.1% (6/147) of them having anti- IgG only. The remaining 88.7% (141/159) had anti- Toxoplasma antibodies IgG, IgA and IgM in various combinations and consisted of 17.7% (25/141) in their first, 44.0% (62/141) in their second, and 38.3% (54/141) in their third, trimesters. Twelve women (7.6%) were seronegative for all 3 antibodies Conclusions: Seroprevalence was high among the women and exposure to contact with cats’ faeces was found to be the major T. gondii infection risk factor. Age and pregnancy-related risk factors did not have association with T. gondii infection within the limitations of this study.
Ad Alta : Journal of Interdisciplinary Research , 2011,
Abstract: The paper deals with searching for meteors in digital astronomical images.Hough transformation for searching for straight lines was used. Four functions werecreated on the basis of this method for various types of meteoric snaps. Graphic UserInterface (GUI) for handling of functions and the database of snaps was created on thebasis of MATLAB. MATLAB tool Image Processing Toolbox was used for imageprocessing as well.

Valdivia compact Abelian groups
Wieslaw Kubi
Mathematics , 2007, DOI: 10.1007/BF03191818
Abstract: Let R denote the smallest class of compact spaces containing all metric compacta and closed under limits of continuous inverse sequences of retractions. Class R is striclty larger than the class of Valdivia compact spaces. We show that every compact connected Abelian group which is a topological retract of a space from class R is necessarily isomorphic to a product of metric groups. This completes the result of V. Uspenskij and the author, where a compact connected Abelian group outside class R has been described.
Fra?ssé sequences: category-theoretic approach to universal homogeneous structures

Mathematics , 2007,
Abstract: We develop category-theoretic framework for universal homogeneous objects, with some applications in the theory of Banach spaces, linear orderings, and in topology of compact spaces.
Injective objects and retracts of Fra?ssé limits
Wieslaw Kubi
Mathematics , 2011, DOI: 10.1515/forum-2012-0081
Abstract: We present a purely category-theoretic characterization of retracts of Fra\"iss\'e limits. For this aim, we consider a natural version of injectivity with respect to a pair of categories (a category and its subcategory). It turns out that retracts of Fra\"iss\'e limits are precisely the objects that are injective relatively to such a pair. One of the applications is a characterization of non-expansive retracts of Urysohn's universal metric space.
Banach-Mazur game played in partially ordered sets
Wieslaw Kubi
Mathematics , 2015,
Abstract: We present a version of the Banach-Mazur game, where open sets are replaced by elements of a fixed partially ordered set. We show how to apply it in the theory of Fraisse limits and beyond, obtaining simple proofs of universality of certain objects and classes.
