Erratum

The caption for figure 1 (p. 1497) of the report "Transformation by v-sis occurs by an internal autoactivation mechanism" by B. E. Bejcek et al. (29 Sept., p. 1496) was inadvertently not printed. The caption should have read, "Fig. 1. (A) Plasmid pSEB3 (B) Mutations used."     

Erratum

In the report "Similarity of synthetic peptide from human tumor to parathyroid hormone in vivo and in vitro," by N. Horiuchi et al. (11 Dec., p. 1566), the caption for figure 1 was inadvertently omitted. The figure is reprinted below with the caption. [See Fig. 1. in Source PDF].     

Erratum

In equation 6 of the Research Article "Effects of age on dopamine and seratonin receptors measured by positron tomography in the living human brain" by D. F. Wong et al. (21 Dec., p. 1393) C(p)(t) in the denominator of the last term should have been A(cb)(t). This does not affect the rest of the derivation. In the caption of figure 1, the first word, "Decrease," should have been "Change." The data in parts A and B of figure 3 should have been regraphed on common axes to facilitate comparison. A corrected figure 3 is shown below.     

Erratum

In the report "Malaria parasites adopt host cell superoxide dismutase" by A. S. Fairchild et al. (19 Aug., p. 764), the caption for figure 2 on page 765 was incorrect and should read as follows: "Comparison of host and parasite SOD's (9) by (A) polyacrylamide gel electrophoresis (8) and (B) isoelecteric focusing (7). Gels were stained for SOD activity (10), and bovine erythrocyte SOD (Sigma, type 1) was used as a reference [pI = 4.95 (13)]. Lane 1, rat-derived P. berghei SOD; lane 2, rat erythrocyte SOD (pI = 5.1); lane 3, mouse-derived P. berghei SOD; lane 4, mouse erythrocyte SOD (pl = 5.7); lane 5, bovine erythrocyte SOD." The pI's of mouse and rat erythrocyte SOD's cited in the text should also be corrected to the values given above.     

Erratum

Figure 1 in the report "Muscle fatigue and the role of transverse tubules" by C. P. Bianchi and S. Narayan (15 Jan., p. 296) was inadvertently transposed with figure 2 in the report "Sedimentation field flow fractionation of liposomes" by J. J. Kirkland et al. (p. 297). The figure legends are correct.     

Erratum

In the report "A plant leucine zipper protein that recognizes an abscisic acid element" by M. J. Guiltinan et al. (12 Oct., p. 267), figure 2 (p. 269) was incorrectly printed. The legend was correct. The correct figure appears below.     

Erratum

In the article by R. Hekinian et al. (28 Mar., p. 1433), in line 3 of the caption for Fig. 7 (p. 1440), "Fe-rich clay-like material" should have read "Fe-bearing opaline material."     

Erratum

Figure 2, part B (p. 100) in the report "Regulation of transendothelial neutrophil migration by endogenous interleukin-8" by A. R. Huber et al. (4 Oct., p. 99) was printed incorrectly. The correct figure (parts A, B, and C) appears below. [See figure in the pdf file].     

Corrections and clarifications

In the report "A link between cyclin A expression and adhesion-dependent cell cycle progression" by T. M. Guadagno et al. (3 Dec., p. 1572), figure 2B on page 1573 was incorrectly printed. The correct figure appears below. [See Figure in the PDF file].     

Erratum

In line 7 of the caption for table 1 (p. 1682) of the report "Association of transfer RNA acceptor identity with a helical irregularity" by William H. McClain et al. (23 Dec., p. 1679), ">/=20%" should have been "相似文献   

Erratum

In the Research Article "The cholinergic neuronal differentiation factor from heart cells is identical to leukemia inhibitory factor" by T. Yamamori et al. (15 Dec., p. 1412), figure 2 (p. 1414) was printed incorrectly. The correct figure appears below. See Table in the PDF file.     

Corrections and clarifications

In the article "Molecular basis of mammalian sexual determination: Activation of Müllerian inhibiting substance gene expression by SRY" by C. M. Haqq et al. (2 Dec., p. 1494), parts B and C of figure 1 were inadvertently interchanged. In figure 3A, the third, fourth, and fifth lanes should have been labeled "A(7) --> T," "A(7) -->C," and "A(7) --> G," respectively. In figure 5, the factor labeled "SRIF's" should have been labeled "SRYIF's."     

Corrections and clarifications

Figure 2C (p. 827) of the Report "Prevention of vertebrate neuronal death by the crmA gene" by V. Gagliardini et al. (11 Feb., p. 826) was incorrectly printed. The correctly printed figure is shown below.     

Erratum

The first sentence of the caption for the figure on page 525 accompanying Marcia Barinaga's Research News artide "Neuroscience models the brain" (2 Feb., p. 524) should have read, "Computer simulation by Kenneth D. Miller models formation of ocular dominance columns." The photo credit fbr the figure should have been to Kenneth D. Miller.     

Corrections and clarifications

Throughout the Research Article "Autoproteolysis in hedgehog protein biogenesis" by John J. Lee et al. (2 Dec., p. 1528) the word "disc" was incorrectly spelled "disk." In figure 4C (p. 1531), lane 9 should have been labeled "flu227," not "flu408."     

Erratum

In the report "Monoclonal antibodies in the lymphatics: Selective delivery to lymph node metastases of a solid tumor" by J. N. Weinstein et al. (28 Oct., p. 423), figure 2 was printed incorrectly. In the bar graph on the left, the captions under N = 13 and N = 4 were interchanged. The correct figure is printed below. [see figure source pdf.].     

Erratum

As published, figure 2 in the report "Disruption of the terrestrial plant ecosystem at the Cretaceous-Tertiary boundary, western interior" by R. H. Tschudy et al. (7 Sept., p. 1030) contained two errors. The break in the stratigraphic column should have been 3 m, and the iridium concentration should have been in parts per trillion. The correct figure is reproduced below. [see figure in source PDF].     

Erratum

In the report "Growth inhibitor from BSC-1 cells closely related to platelet type beta transforming growth factor" by Ronald F. Tucker et al. (9 Nov., p. 705), figures 1 and 2 on page 706 were incorrectly interchanged. The figure captions are correct.     

Corrections and clarifications

In the Research News article "Pot, heroin unlock new areas for neuroscience" by Marcia Barinaga (18 Dec., p. 1882), the diagram of the molecule anandamide on page 1883 was incorrect. The correct structure appears on page 1948 of the same issue, in figure 1A of the report "Isolation and structure of a brain constituent that binds to the cannabinoid receptor" by W. A. Devane et al. (p. 1946).
