The function of γδ T cells in humoral immune responses.

Purpose: The purpose of this review is to discuss the role of γδ T cells played in humoral immune responses.

Background: The γδ T cell receptor (γδ TCR) recognizes antigens, including haptens and proteins, in an MHC-independent manner. The recognition of these antigens by γδ TCRs crosses antigen recognition by the B cell receptors (BCRs), suggesting that γδ T cells may be involved in the process of antigen recognition and activation of B cells.

A Preliminary Study of the Effects of Venous Drainage Position on Arterial Blood Supply and Venous Return within the Conjoined Flap.

Background: Conjoined flap viability is associated with arterial blood supply and venous return. This study aimed to assess the effects of venous drainage position on arterial blood supply and venous return within the conjoined flap.

Methods: Fifty-four rats were divided randomly into three groups (n = 18 per group).

catena-Poly[[(2,9-dimethyl-1,10-phenanthroline-κN,N')cobalt(II)]-μ-malonato-κO,O:O,O].

In the title compound, [Co(C(3)H(2)O(4))(C(14)H(12)N(2))](n), the Co(II) ion is in a distorted octa-hedral coordination being chelated by a 2,9-dimethyl-1,10-phenanthroline mol-ecule (dmphen) and two carboxyl-ate groups of two malonate ligands The malonate ligand acts in a bridging mode, forming coordination chains along [100]. π-π stacking inter-actions between dmphen ligands [inter-planar distances = 3.414 (4) and 3.

catena-Poly[4,4'-bipyridinium [[diaqua-disulfatocadmium(II)]-μ-4,4'-bipyridine-κN:N'] dihydrate].

The title compound, {(C(10)H(10)N(2))[Cd(SO(4))(2)(C(10)H(8)N(2))(H(2)O)(2)]·2H(2)O}(n), consists of anionic chains of the Cd complex, diprotonated 4,4'-bipyridinium cations and uncoordinated water mol-ecules. In the anionic chain, the Cd atom lies on a center of inversion in an octa-hedral geometry. The midpoint of the coordinated bipyridine also resides on a center of inversion, as does the non-coordinated bipyridinium counterion.
