Allogeneic fetal stem cell transplantation to child with psychomotor retardation: A case report [PDF]
Srpski Arhiv za Celokupno Lekarstvo, 2016 Introduction. The consequences of autologous and allogeneic stem cell transplantation (stem cells of hematopoiesis), applied in adults and children suffering from leukemia or some other malignant disease, are well-known and sufficiently ...

Computational Geometry, 2007 The paper is focused on the so called localization problem which can be characterised as a determination of certain topological features within a space. While the topology, and especially the homology gives the information about the existence of the topological features and attributes, the information about their location cannot be directly known.

Homology operations in symmetric homology [PDF]
Homology, Homotopy and Applications, 2014 The symmetric homology of a unital associative algebra $A$ over a commutative ground ring $k$, denoted $HS_*(A)$, is defined using derived functors and the symmetric bar construction of Fiedorowicz. In this paper we show that $HS_*(A)$ admits homology operations and a Pontryagin product structure making $HS_*(A)$ an associative commutative graded ...

Distinct roles for two RAD51-related genes in Trypanosoma brucei antigenic variation [PDF]
, 2005 In Trypanosoma brucei, DNA recombination is crucial in antigenic variation, a strategy for evading the mammalian host immune system found in a wide variety of pathogens.

An interpretation of E n -homology as functor homology [PDF]
Mathematische Zeitschrift, 2010 We prove that E_n-homology of non-unital commutative algebras can be described as functor homology when one considers functors from a certain category of planar trees with n levels. For different n these homology theories are connected by natural maps, ranging from Hochschild homology and its higher order versions to Gamma homology.

Role of hydrophobic interaction in hapten-antibody binding [PDF]
, 1977 The precipitation reaction of bovine serum albumin coupled with p-azophenylleucine with homologous antibody was inhibited by several structurally related haptens. The isobutyl group substituent on alpha-carbon atom of the leucine residue contributed more

Canadian Journal of Mathematics, 2003 AbstractFor complex projective manifolds we introduce polar homology groups, which are holomorphic analogues of the homology groups in topology. The polar k-chains are subvarieties of complex dimension k with meromorphic forms on them, while the boundary operator is defined by taking the polar divisor and the Poincaré residue on it. One can also define

Ultrastructural analysis of chromatin in meiosis I plus II of rye (Secale cereale L.) [PDF]
, 2004 Scanning electron microscopy (SEM) proves to be an appropriate technique for imaging chromatin organization in meiosis I and II of rye (Secale cereale) down to a resolution of a few nanometers.
