We give an explicit description of the coefficients of the formal power series (1− x)(1− x)(1 − x)(1− x)(1 − x)(1− x) · · ·. In particular, we show that all the coefficients are equal to −1, 0 or 1. The Fibonacci numbers are defined by the recurrence relation Fn+2 = Fn+1+ Fn for n ≥ 0, and the initial conditions F0 = 0, F1 = 1. Consider the infinite product A(x) = ∏ k≥2(1− x k) = (1− x)(1 − x)(...

Chronic kidney disease (CKD) is characterized by progressive interstitial fibrosis and tubular atrophy, leading to failure. There no effective treatment for fibrosis, current medications at best reduce the rate of function deterioration. Accumulation fibronectin (FN) in tubulo-interstitium occurs outset tubulo-interstitial fibrotic lesions contain FN isoforms notably extra domain A-spliced vari...

BACKGROUND Fibronectin (FN) undergoes fragmentation in periodontal disease sites and in poorly healing diabetic wounds. The biologic effects of FN fragments on wound healing remain unresolved. This study characterized the pattern of FN fragmentation and its effects on cellular behavior compared to intact FN. METHODS Polyclonal antibodies were raised against FN and three defined recombinant se...

In this paper, we show that for any positive integer k, the set {( φ(Fn+1) φ(Fn) , φ(Fn+2) φ(Fn) , . . . , φ(Fn+k) φ(Fn) )

Background: Bone mineral density (BMD) changes during the course of rheumatoid arthritis (RA). The present study was designed to investigate the status of BMD in patients with RA treated with anti-rheumatic drugs. Methods: BMD at the femoral neck (FN-BMD) and lumbar spine (LS-BMD) were measured by dual energy x-ray absorptiometry (DXA) method using Norland densitometer. Disease activity (DA) wa...

The role of endogenously synthesized fibronectin (FN) in assembly was studied with cells lacking or expressing FN. Cells were cultured as homogeneous or mixed populations on surfaces coated with different matrix proteins. Compared with FN-expressing cells, FN-null cells poorly assembled exogenous plasma FN (pFN) when adhered to vitronectin or the recombinant cell-binding domain (III(7-10)) of F...
