Data indicate that refrigerated osteochondral allografts can be maintained for up to 44 days with average chondrocyte viability of 67%, indicating less matrix staining in grafts refrigerated longer after harvest.

Findings show that PASMCs acutely exposed to hypoxia exhibit a marked increase in intracellular DCF fluorescence, suggestive of reactive oxygen or nitrogen species production.
Toxocara canis: failure to find IgE receptors (Fc epsilon R) on eosinophils from infected mice suggests that murine eosinophils do not kill helminth larvae by an IgE-dependent mechanism.

Eosinophils obtained by bronchoalveolar lavage from the lungs of mice infected with Toxocara canis were characterized by flow cytometry with respect to cytophilic antibodies and surface Fc receptors and may indicate different functional activities for mouse BAL eosInophils in helminth infections.

It is concluded that ANs enhance the adhesion of SRBCs to vascular endothelium by increasing red blood cell membrane externalization of PS.
Intracellular calcium puffs in osteoclasts.

It is concluded that [Ca(2+)](i) transients in osteoclast are increased in acid-secreting osteoclasts, and that the puffs occur mainly near the acid-transporting membrane.
Increased oxygen tensions influence subset composition of the cellular immune system in aged mice.
The suggestion is made that the immune system has a reserve capacity that can be influenced by oxygen and is theoretically capable of being pharmacologically manipulated to assist patients with altered immune systems to promote defense mechanisms or, under certain circumstances, reduce autoimmunity.
Rheumatoid arthritis: an immune complex disease? A review of the reaction of antigen with antibody to form immune complexes and the mechanisms by which they mediate tissue injury.
THE STRUCTURAL BASIS FOR BINDING OF COMPLEMENT BY IMMUNOGLOBULIN M

Structural considerations and sequence overlaps suggest that the amino-terminal side of the CH4 domain (24 amino acid residues) might be responsible for fixing C1.
Modulation of human T cell production of migration inhibitory lymphokines by cytokines derived from human leukocyte dialysates.

The amplifiers were found to increase LIF and MIF production by antigen- or alloantigen-stimulated human peripheral blood lymphocytes in a dose-dependent fashion and demonstrated that although antigen- Stimulated T4 and T8 cell subpopulations could produce LIF activity under the assay conditions employed, amplification of lymphokine production by modulator was only observed with the T4 subset.
