Background: Differentiating oligodendrocyte precursor cells (OPCs) into oligodendrocytes could be improved by inhibiting signaling pathways such as Wnt and Notch. 9-cis-retinoic acid (9-cis-RA) and 1,25-dihydroxyvitamin D3 (1,25[OH]2D3) can ameliorate oligodendrogenesis. We investigated whether they could increase oligodendrogenesis by inhibiting the Wnt and Notch signaling pathways.Methods: Co...

conclusions our study demonstrated that almost all ghq and msscq parameters were lower in ra patients, which indicates lower quality sexual life in ra patients. we recommend further consideration for the treatment and care of these patients. patients and methods in this case-control study, two groups of females (87 ra patients and 89 controls) were randomly selected from the rheumatology clinic...

conclusions our findings suggest that there is an association between the mthfr c677t polymorphism and susceptibility for the development of ra. results our results showed significant differences between the groups with respect to mthfr c677t genotype (p = 0.015) and allele frequencies (0.004). statistical analysis showed that there is no relation between gender, age, and ra risk. however, we fo...

Rheumatoid arthritis (RA) is a chronic disease, the etiology of which has yet to be clarified, which causes activation of proinflammatory pathways that bring about joint and systemic inflammation. In recent years, the pathophysiology of CNS involvement that can occur in RA has attracted a great deal of attention. Emphasis has focused on the possibility that CNS involvement occurs due to bl...

in nonnegative integers x, y and integers u, v ∈ {0, 1}. Note that the choice of x and y uniquely determines the choice of u and v, so we will usually refer to a solution (x, y). The Case (ra, sb) = 1 There are only a finite number of cases with N > 3 solutions to Equation (P) [23]. There are at least five infinite families of cases with N = 3 solutions to (P), as well as a number of anomalous ...
