(n.) A variety of carnelian, of a rich reddish yellow or brownish red color. See the Note under Chalcedony.
Example Sentences:
(1) It is proposed that all SARDs act on some aspect of the central reaction in the ongoing immune response where antigen presentation to T helper cells results in interleukin 2 production and the generation of activated T cells.
(2) The effects produced by a single agent in vivo and in vitro are not always the same so a single mode of action, for example through possession of a thiol group, cannot explain the effects of all SARDs.
(3) Review of the known activity of SARDs on different cell types at various anatomical sites suggest that in fact different SARD drugs act in differing and sometimes conflicting ways.
(4) Whether these findings explain the low incidence of SARD with cuprammonium cellulose plate dialyzers that do not contain potting material is a matter for continued study and experimentation.
(5) Plasma, bronchoalveolar lavage fluids (BAL), and lung parenchyma were analyzed for vitamin E and polyunsaturated fatty acid (PUFA) concentrations in three groups of patients routinely receiving oxygen therapy--two with adult respiratory distress syndrome (ARDS and SARDS), a third with pneumonia (PNEU), as well as a fourth group of patients receiving little or no oxygen therapy (OTHER).
(6) However, none of the SARDs examined could scavenge O2- at concentrations reported in patients' plasma.
(7) This approach for combination therapy whereby a second SARD is given to patients already established on a single SARD, appears to minimise the toxicity which is a problem when 2 SARDs are started simultaneously.
(8) "These instruments were not invented by Greece, nor did investment banks discover them just for Greece," said Christophoros Sardelis, who was chief of Greece's debt management agency when the contracts were conducted with Goldman Sachs.Such contracts were also used by other European countries until Eurostat, the EU's statistic agency, stopped accepting them later in the decade.
(9) During the first year none of the reactions were serious although 9 of the 29 patients (31%) given D-penicillamine and 3 of the 9 patients receiving aurothiomalate developed side-effects requiring withdrawal of the second SARD.
(10) A gas chromatographic system with wide-bore capillary columns and synchronized accumulating radioisotope detector (SARD) was developed.
(11) The site of action of SARDs within the body--whether at the level of synovial inflammation or of the systemic immune response--is largely undetermined.
(12) Since many drugs, particularly the slow-acting anti-rheumatic drugs (SARDs) used in RA, may alter O2- metabolism, the effects of SARDs on SSA were also studied.
(13) The performance of wide-bore capillary columns was good and the correspondence of the resolution obtained with SARD and that with mass detection was excellent.
(14) This open study examined the safety of adding a second slow-acting anti-rheumatic drug (SARD) - D-penicillamine or sodium aurothiomalate - to the therapy of 38 rheumatoid patients already established on sulphasalazine.
(15) The slow acting anti-rheumatic drugs (SARDS) are a chemically heterogeneous group.
(16) The SSA of the plasma, PB-PMN, JF and JF-PMN were significantly higher in patients treated with SARDs than those without.
