Let an count the number of 2-dimensional rook paths Rn,n from (0, 0) to (2n, 0). Rook pathsRm,n are the lattice paths from (0, 0) to (m+n,m−n) with allowed steps (x, x) and (y,−y) where x, y ∈ N+. In answer to the open question proposed by M. Erickson et al. (2010), we shall present a combinatorial proof for the recurrence of an, i.e., (n + 1)an+1 + 9(n − 1)an−1 = 2(5n + 2)an with initial condi...
aluminum base composite materials with variable properties which have been strengthened by alb 2 particles have been widely used. in this study, composites with variable properties of al-5%b and al-2%mg-2%b which are produced through centrifugal casting are investigated as far as their microstructure and hardness are concerned. the microstructure of these composite were studied by using metallo...
OBJECTIVES Neuromyelitis optica spectrum disorder (NMOSD) is a severe inflammatory disorder of the central nervous system (CNS) targeted against aquaporin-4 (AQP4). The origin and trafficking of AQP4-specific B cells in NMOSD remains unknown. METHODS Peripheral (n = 7) and splenic B cells (n = 1) recovered from seven NMOSD patients were sorted into plasmablasts, naïve, memory, and CD27-IgD- d...
Autoimmune lymphoproliferative syndrome (ALPS) caused by impaired FAS-mediated apoptosis of lymphocytes is characterized by lymphoproliferation, autoimmunity, but also an increased risk of invasive bacterial infection, notably following splenectomy. We surveyed a cohort of 100 ALPS patients (including 33 splenectomized) and found that 12 (10 splenectomized) had experienced 23 invasive bacterial...
Nitrogen stable isotope ratios (dN) have successfully been applied in the study of trophic linkages, as well as of human impacts in aquatic ecosystems. Anthropogenic wastewater input typically elevates dN values in dissolved inorganic nitrogen and this N enrichment subsequently propagates throughout the food chain. Bivalve mollusks are of interest for studies of this human influence since they ...
Introduction. Although commonly classified as a Negative Concord (NC) language since it readily allows single negation readings of Negative Concord Items (NCI) sequences (1c), French has widely been acknowledged to also tolerate Double Negation (DN) or Negative Discord, albeit as a marked option (De Swart, Corblin, 1996). This DN tolerance, diagnosed by Zeijlstra (2004) as a symptom of the stil...
Background and Aims: Substantial damage to the kidney tissue and diabetic nephropathy (DN) can be caused by chronic hyperglycemic conditions and exposure to a high level of blood glucose. In the current study, we explored the capability of adipose-derived mesenchymal stem cells (ADSCs) and Toll-like receptor-4-primed mesenchymal stem cells (TLR4-primed MSCs) on kidney regeneration, resolution ...
diabetic nephropathy is common in mazandaran and a significant number of patients under chornic hemodialysis are diabetics. the present study was designed to study the prevalence and predisposing factors of diabetic nephropathy (dn) in mazandaran. methods: during a 20 months period from june 1993 through december 1994, 490 (350 female, 140 male) cases of non-insulin dependent diabetes mellitus ...
