Materials and methods Example
Materials and methods
Materials. Culture media were obtained from Life Technologies
(Gaithersburg, MD). Okadaic acid was purchased from Alexis Company
(Läufelfingen, Switzerland). Antibodies to MEK1/2 and phosphorylated
MAPK were purchased from New England Biolabs (Beverley, MA).
Materials described first
Suppliers/locations given
Induction of cell death. Cell death was induced as described previously [15].
Briefly, cell death was induced by adding okadaic acid (0-300 nM, Alexis Co.)
after washing slice cultures in serum-free medium.
Clear subheadings
Refs used to save space
Light and electron microscopy. Cultures were fixed in 2.5% glutaraldehyde
and 1% formaldehyde, treated with 1% OsO4 in 0.1 M phosphate buffer, pH
7.4, dehydrated in a graded series of ethanol and propylene oxide, and flatembedded in an epoxy resin (Durcupan ACM, Fluka, Neu-Ulm, Germany).
Semithin sections were stained with toluidine blue, and ultrathin sections
were stained with 1% uranyl acetate for 20 min and 1% lead citrate for
2 min.
Enough information to
reproduce the experiment
Statistics. For statistical analysis, 2-tailed Student’s t test was used to assess
the significance of mean differences. Differences were considered significant
at a P value of 0.05 or less.

Results Example
Results
Okadaic acid induces death of dentate gyrus neurons selectively.
Hippocampal slice cultures treated with OA (1–300 nM) showed selective
cell death of neurons in the dentate gyrus, but neurons in the CA1–3 regions
were largely unaffected. Cell death occurred in a time- and dose-dependent
manner. Propidium iodide staining of treated slides indicated….
Electron microscopy revealed a number of ultrastructural changes in
hippocampal pyramidal neurons, particularly those in the CA3 region, in
slices treated with 300 nM OA for 24 h (Fig 3). These changes included slight
nuclear aggregations (arrow in Fig 3A), accumulation of mitochondria
around nuclei (arrowheads in Fig 3B) and an increased amount of
endoplasmic reticulum (Fig 3C). As shown in Figure 4, the nuclei of
pyramidal neurons in the CA1 and CA3 regions…
Involvement of MAPK signaling in the effect of OA. Compared with slices
treated with medium only and treated slices at 0 h, slices treated with 300
nM OA showed increasing levels of phosphorylated MAPK at 4 h, 8 h, 16 h
and 24 h, with no corresponding change in the levels of total MAPK. This
increase was prevented in slices that were co-incubated with a protein
kinase inhibitor. In addition, the levels of phosphorylated Tau were higher in
OA-treated slices than in control slices…

pathogenesis of M. pneumoniae-associated CNS disease, development of
more reliable serologic assays, and defining the role of quantitative PCR in
distinguishing acute infection from asymptomatic carriage and prolonged
post-infection shedding”

“The Clinical Trial Service Unit has a staff policy of not
accepting honoraria or other payments from the
pharmaceutical industry, except for the reimbursement of
costs to participate in scientific meetings. Coordinating centre
members of the writing committee (R Collins, J Armitage, S
