Let n be the number of genotypes, m be the number of markers and l be the number of environments.
Linkage map coverage c was estimated as c = 1 - e -2dn/L, with d being the average distance of markers in the linkage map, n the number of markers, and L the length of the linkage map.
In conclusion, when compared with other risk factors (age, body size, bone turnover markers, and L-BMD[T]), al-BMD measurements showed a higher association with vertebral and long bone fractures than L-BMD and could successfully identify those patients who had sustained a fracture in the multivariate analysis.
The genome coverage of the linkage map (c) was next estimated by calculating c = 1 - e -2dn/L, where d is the average interval of markers, n is the number of markers, and L is the length of the linkage map estimated above.
Independence and uniqueness of DArT markers were evaluated by calculating the linkage index I k, l for each possible pair of markers k and l, according to the following formula: I k, l = 1 n ∑ | m k i − m l i | where n is the number of individuals, m ki the score (0/1) of individual i at marker k, and m li the score of individual i at marker l.
Liver tissue with metastases was additionally analyzed for cytokines, T cell markers and Fas/Fas-L expression using immunohistochemistry, immunofluorescence and RT-PCR.
By comparing amplified tumour DNA profiles with matching normal DNA, a tumour is classified as MSI-H when it shows instability in at least two of the five markers and MSI-L or MSS when it shows instability at one or none of the markers, respectively (Boland et al, 1998).
Dashed lines and markers L and M correspond to the width of deformation after 350 km of shortening.
(I – L ) Relative mRNA expression levels of M1 macrophage markers TNF1a, Itgax, and IL12b (I and J ) and the M2 macrophage marker Mgl2 (K and L ) assessed by quantitative PCR in epididymal adipose tissue of global Alk7 −/− (I and K ) and fat-specific Alk7 fx/fx:: Ap2 CRE (J and L ) knock-out mice after 16 weeks on HFD.
*FM-A: Full model - pedigree-based; FM-RR: Full model - ridge regression with marker data; FM-RRA: Full model - combined ridge regression with markers and pedigree data; FM-L: full model - the least absolute shrinkage and selection operator; FM-LA: full model – combined least absolute shrinkage and selection operator, and pedigree information.
