Abstract:
Seroprevalence among blood donors is a major public health problem, both in developed and developing countries, in its magnitude. The aim of this study was to determine the seroprevalence of hepatitis B in blood donors. This is a descriptive study carried out in the city of Mbuji-Mayi at the General Hospital of Dipumba in blood donors (family, volunteer and remunerated) recorded from 01/to31/December 2016; the data were collected in a transverse fashion. The following observations were made: During the study period, 1584 blood donors were registered. After analyzing the data, the seroprevalence of hepatitis B in blood donors was 2.2%, 77.8% were male (sex ratio M/F 3.5 and voluntary donors were 50.4%.

Abstract:
Objectives: The objective of this work was to analyze the etiologies of maternal deaths occurring in a tertiary hospital. Methodology: This is a descriptive cross-sectional study with retrospective data collection of maternal deaths that occurred in the reference provincial hospital Jason Sendwe from 2013 to 2015. All cases of maternal deaths in line with the definition of World Health Organization have been included. Data were analyzed by the software Epi info and Excel 2010 7.1.4.0. Results: Seventy seven (77) maternal deaths were identified during the study period. 74.03% of deaths occurred direct obstetric causes. Bleeding with 61.04% was the leading cause of maternal death followed by eclampsia (31.58%). Indirect causes were dominated by heart disease (30.0%). Note that 75.32% of deaths had occurred within 24 hours of admission. Conclusion: haemorrhage, eclampsia and infections are the main causes of maternal deaths in our study. The reduction of maternal deaths happens through access to emergency medication, transfusion and anesthetic and surgical teams in hospitals but also through the involvement of religious leaders, traditional and any community to better understand the population obstacles to reducing maternal mortality.

Abstract:
Vaginal haemorrhages outside pregnancy in women of childbearing age are a major public health problem in both developed and developing countries. The purpose of this study was to determine the frequency and causes of vaginal haemorrhage outside pregnancy. This is a descriptive study conducted in the city of Mbuji-Mayi at Bonzola General Hospital, registered from 01 to 31 December 2017; the data were collected transversally. The following observations were made during the study period; 174 women of childbearing age were registered. After analyzing the data, the incidence of vaginal haemorrhage in women of childbearing age was 15.8% and the main causes were: cervical cancer: 32.7% and uterine myoma 22.5%.
Pairings of Sheaves of $\mathcal{A}$-Modules through Bilinear $\mathcal{A}$-Morphisms
A. Mallios,PP Ntumba
Mathematics , 2008,
Abstract: It is proved that for any free $\mathcal{A}$-modules $\mathcal{F}$ and $\mathcal{E}$ of finite rank on some $\mathbb{C}$-algebraized space $(X, \mathcal{A})$ a \textit{degenerate} bilinear $\mathcal{A}$-morphism $\Phi: \mathcal{F}\times \mathcal{E}\longrightarrow \mathcal{A}$ induces a \textit{non-degenerate} bilinear $\mathcal{A}$-morphism $\bar{\Phi}: \mathcal{F}/\mathcal{E}^\perp\times \mathcal{E}/\mathcal{F}^\perp\longrightarrow \mathcal{A}$, where $\mathcal{E}^\perp$ and $\mathcal{F}^\perp$ are the \textit{orthogonal} sub-$\mathcal{A}$-modules associated with $\mathcal{E}$ and $\mathcal{F}$, respectively. This result generalizes the finite case of the classical result, which states that given two vector spaces $W$ and $V$, paired into a field $k$, the induced vector spaces $W/V^\perp$ and $V/W^\perp$ have the same dimension. Some related results are discussed as well.
Abstract Geometric Algebra. Orthogonal and Symplectic Geometries
PP Ntumba,Ac Orioha
Mathematics , 2008,
Abstract: Our main interest in this paper is chiefly concerned with the conditions characterizing \textit{orthogonal and symplectic abstract differential geometries}. A detailed account about the sheaf-theoretic version of the \textit{symplectic Gram-Schmidt theorem} and of the \textit{Witt's theorem} is also given.
On the endomorphisms of some sheaves of functions
Patrice P. Ntumba
Mathematics , 2013,
Abstract: Given a $C^\infty$ real manifold $X$ and $\mathcal{C}^m_X$ its sheaf of $m$-times differentiable real-valued functions, we prove that the sheaf $\mathcal{D}^{m, r}_X$ of differential operators of order $\leq m$ with coefficient functions of class $C^r$ can be obtained in terms of the sheaf $\mathcal{H}om_{\mathbb{R}_X}(\mathcal{C}^m_X, \mathcal{C}^r_X)$ of morphisms of $\mathcal{C}^m_X$ into $\mathcal{C}^r_X$. The superscripts $m$ and $r$ are integers.
Cofibrations in the Category of Frolicher Spaces. Part I
B. Dugmore,PP. Ntumba
Mathematics , 2007,
Abstract: Cofibrations are defined in the category of Fr\"olicher spaces by weakening the analog of the classical definition to enable smooth homotopy extensions to be more easily constructed, using flattened unit intervals. We later relate smooth cofibrations to smooth neighborhood deformation retracts. The notion of smooth neighborhood deformation retract gives rise to an analogous result that a closed Fr\"olicher subspace $A$ of the Fr\"olicher space $X$ is a smooth neighborhood deformation retract of $X$ if and only if the inclusion $i: A\hookrightarrow X$ comes from a certain subclass of cofibrations. As an application we construct the right Puppe sequence.
On $\mathcal A$-Transvections and Symplectic $\mathcal A$-Modules
Patrice P. Ntumba
Mathematics , 2009,
Abstract: In this paper, building on prior joint work by Mallios and Ntumba, we show that $\mathcal A$-\textit{transvections} and \textit{singular symplectic }$\mathcal A$-\textit{automorphisms} of symplectic $\mathcal A$-modules of finite rank have properties similar to the ones enjoyed by their classical counterparts. The characterization of singular symplectic $\mathcal A$-automorphisms of symplectic $\mathcal A$-modules of finite rank is grounded on a newly introduced class of pairings of $\mathcal A$-modules: the \textit{orthogonally convenient pairings.} We also show that, given a symplectic $\mathcal A$-module $\mathcal E$ of finite rank, with $\mathcal A$ a \textit{PID-algebra sheaf}, any injective $\mathcal A$-morphism of a \textit{Lagrangian sub-$\mathcal A$-module} $\mathcal F$ of $\mathcal E$ into $\mathcal E$ may be extended to an $\mathcal A$-symplectomorphism of $\mathcal E$ such that its restriction on $\mathcal F$ equals the identity of $\mathcal F$. This result also holds in the more general case whereby the underlying free $\mathcal A$-module $\mathcal E$ is equipped with two symplectic $\mathcal A$-structures $\omega_0$ and $\omega_1$, but with $\mathcal F$ being Lagrangian with respect to both $\omega_0$ and $\omega_1$. The latter is the analog of the classical \textit{Witt's theorem} for symplectic $\mathcal A$-modules of finite rank.
An antibody present in everybody that attacks malaria infected erythrocytes  [PDF]
James Kennedy
Journal of Biomedical Science and Engineering (JBiSE) , 2013, DOI: 10.4236/jbise.2013.67A1001
Abstract: These malaria targeting antibodies are band 3 antibodies and they recognize a special configuration of a molecule called band 3 that is present on erythrocytes. The special band 3 configuration is present on the surface of senescent erythrocytes, malaria infected erythrocytes, the erythrocytes of certain hemoglobinnopathies such as sickle cell disease and on the erythrocytes of some metabolic disorders such as G6PD. Note that these hemoglobinopathies and metabolic disorders all aid in the survival of falciparum malaria to such an extent that their incidence is increased in falciparum endemic areas [1-3]. Though there are many adhesive molecules involved in the pathology of falciparum malaria and sickle cell anemia, the focus here is on the band 3 molecules.
