Kaplan-Meier survival functions (PROC LIFETEST) were performed initially to illustrate differences in the duration of lesions between primi- and multiparous cows and between three different stages in lactation at onset (stage 1: 0–120 DIM; stage 2: 121–240 DIM; stage 3: > 240 DIM).
In a prospective design he could show that 'the social course (of schizophrenia) is determined by individual stage at illness onset and by early illness course' [ 70].
To recognize leaves that were at a comparable developmental stage at the onset of the experiment, the main stem below the 10th internode from the upper leaf was marked on all the plants at the onset of treatments.
Longitudinal gene expression analyses were obtained at different time points within a week from spinal cord compression injury and at a pre-symptomatic stage, at disease onset and end-stage in the G93A SOD1 mutant rats.
It is interesting that, although the expression of fezf2 in the forebrain starts from the early patterning stage, its effect on Wnt/β-catenin signalling only becomes apparent from the tailbud stage at the onset of neuronal differentiation.
All 59 consecutive children over the age of 1 year with stage 4 neuroblastoma at onset observed at the Istituto Nazionale Tumori of Milan during the study period were enrolled.
In the late stages, at the onset of symptoms, the first generation tumours recapitulated the invasive features of the parent tumours like previously reported, but were largely devoid of angiogenesis and necrotic areas.
Kaplan-Meier survival functions and Cox proportional hazard regression were performed to estimate the duration and analyse differences in the duration of lesions between primi- and multiparous cows and between different stages in lactation at onset of the lesion.
These include the expression profiles of pooled thoracic cord samples at 30 minutes, 4 hours, 24 hours and 7 days from injury, at 30 minutes and 4 hours from sham-operation and the expression profile of pooled SOD1 G93A mutant thoracic cord samples and of pooled wild type (WT) littermates at a pre-symptomatic stage (10 weeks of age), at onset and at end-stage disease.
Though we observed a slight but significant reduction in the percentage of activated microglia and astrocytes at onset stage, neither survival nor motor performance of double transgenic mice differ from those of single transgenic ALS mice (Figure 4 5).
