A randomized complete block (RCBD) study was designed to investigate the effects of cadmium (Cd) and copper (Cu) on the growth, bioaccumulation of the two heavy metals, metabolite content and antibacterial activities in Gyanura procumbens (Lour.) Merr. Nine treatments including (1) control (no Cd and Cu); (2) Cd 2 = cadmium 2 mg/L; (3) Cd 4 = cadmium 4 mg/L; (4) Cu 70 = copper 70 mg/L; (5) Cu 1...
ترکیب [cu(hpydc)(dmp)].5h2o (2) (که h2hpydc و dmp، به ترتیب گروههای 4-هیدروکسی پیریدین-2، 6-دی کربوکسیلیک اسید و 2، 9-دی متیل-1، 10-فنانترولین هستند) از روش انتقال پروتون سنتز و ساختار بلوری آن به روش بلورشناسی با پرتو-x تعیین شد. این ترکیب در سیستم بلوری تکمیل و گروه فضایی p2/c متبلور شده است و پارامترهای سلول واحد آن (4)8423/10 a =، (5) 4457/13 b =، (4) 6447/13 c = آنگستروم و (2) 004/90β = ...
Let Cd,k be the largest number of vertices in a Cayley graph of degree d and diameter k. We show that Cd,3 ≥ 3 16(d − 3) 3 and Cd,5 ≥ 25(d−7 4 ) 5 for any d ≥ 8, and Cd,4 ≥ 32(d−8 5 ) 4 for any d ≥ 10. For sufficiently large d our graphs are the largest known Cayley graphs of degree d and diameters 3, 4 and 5.
Although both the CD4 and CD8 molecules enhance antigen responsiveness mediated by the T cell receptor (TCR), it is not known whether CD4 and CD8 initiate similar or different intraceUular signals when they act as coreceptors. To characterize the early signals transmitted by CD4 and CDS, both CD4 and CDSo~ were expressed in the same murine T cell hybridoma. In the double positive transfectants,...
1144 The Journal of Clinical Investigation http://www.jci.org Volume 115 Number 5 May 2005 mal scarring (8). Some of the clinical features of EDS are actually evident in the families with ICH studied by Gensure et al. (6), and this makes sense. But the reason why some ICH patients also develop acute bone lesions at a specific age is not clear. The authors hypothesize that periosteum is only loo...
