Recently discovered interleukin 29 (IL-29) has antiviral properties and its production is induced by herpes viruses. This study was aimed at analyzing the effect of non-surgical periodontal treatment on IL-29 levels in gingival crevicular fluid (GCF) of chronic and aggressive periodontitis patients. A total of 60 participants were divided into healthy group (group 1; n=20), chronic periodontiti...

We denote by LS[N ](t, k, v) a large set of t-(v, k, λ) designs of size N , which is a partition of all k-subsets of a v-set into N disjoint t-(v, k, λ) designs and N = ( v−t k−t ) /λ. We use the notation N(t, v, k, λ) as the maximum possible number of mutually disjoint cyclic t-(v, k, λ)designs. In this paper we give some new bounds for N(2, 29, 4, 3) and N(2, 31, 4, 2). Consequently we presen...
