The PHA-stimulated CD4+ blasts were cultured for 24h in 10% human recombinant IL - conditioned medium( Boehringer ). Cells were pelleted and infected with the primary isolates HIV - 1E80(provided by P. Clapham ),and HIV-1Ba-L,both of ... A set number of CD4+ cells(1x106 cells per vial )were incubated... The Horne-Osberg scores were consistent with our classification scheme: FASPS patients, 76.2+5.6(n=14); unaffected relatives,...

The peptid(KLAKLAK)induced considerable mitochondrial swelling at a concentration of 10µM(Fig.2a).Mild swelling was evident even at 3µM ( data not shown),1 % the concentration required to kill eukarytoic cells (approximately 300µM),as kdetermined by the letal concentration... The clinical sensitivity was significantly improved from 63 % (140/221) to 80 % (177/221) (p<0.001; Table 1). Exercise on 116106526 生物科 M1 科学英語 2014/10/15 Example 2 In American English, periods and commas are within quotation marks, like "this period." Other punctuation is "outside"! Avoid contractions; for example, write "do not" instead of "don't." The serial comma is preferred: "A, B, and C" instead of "A, B and C." Example 3 Use words rather than symbols. As an example, write the quantity "Magnetization," or "Magnetization, M," not just "M." Put units in parentheses. Do not label axes only with units. As in Fig. 1, for example, write "Magnetization (A/m)" or "Magnetization (A m1)," not just "A/m." Example 4 The abbreviation for "seconds" is "s," not "sec." Exercise on 116106526 生物科 M1 科学英語 2014/10/15 Do not mix complete spellings and abbreviations of units: use "Wb/m2" or "webers per square meter," not "webers/m2." When expressing a range of values, write "7 to 9" or "7-9," not “7~9.” A parenthetical statement at the end of a sentence is punctuated outside of the closing parenthesis (like this). (A parenthetical sentence is punctuated within the parentheses.)
