Alon, Kleitman, Lipton, Meshulam, Rabin and Spencer (Graphs. Combin. 7 (1991), no. 2, 97-99) proved, that for any hypergraph F = fF1; F2; : : : ; Fd(q 1)+1g, where q is a primepower, and d denotes the maximal degree of the hypergraph, there exists an F0 F , such that jSF2F0 F j 0 (mod q). We give a direct, alternative proof for this theorem, and we also give an explicit construction of a hyperg...

The National Institute of Standards and Technology (NIST) recently published a Format-Preserving Encryption standard accepting two Feistel structure based schemes called FF1 and FF3. Particularly, FF3 is a tweakable block cipher based on an 8-round Feistel network. In CCS ̃2016, Bellare et. al. gave an attack to break FF3 (and FF1) with time and data complexity $O(Nˆ5\log(N))$, which is much lar...

OBJECTIVES Low levels of physical activity may have considerable negative effects on bone health in adolescence, and increasing screen time in place of sporting activity during growth is worrying. This study explored the associations between self-reported screen time at weekends and bone mineral density (BMD). DESIGN In 2010/2011, 1038 (93%) of the region's first-year upper-secondary school s...

A splitting of an additive Abelian group G is a pair (M; S), where M is a set of integers and S is a subset of G such that every nonzero element g 2 G can be uniquely written as m h for some m 2 M and h 2 S. Splittings of groups by the set M = ff1; : : :; kg are intimately related to tilings of the n{ dimensional Euclidean space. Further, such a splitting corresponds to a perfect shift code use...

RFamide-related peptide-3 (RFRP-3) and neuropeptide FF (NPFF) target two different receptor subtypes called FF1 (NPFF1R) FF2 (NPFF2R) that modulate several functions. However, the study of their respective role is severely limited by absence selective blockers. We describe here design a highly NPFF1R antagonist RF3286, which potently blocks RFRP-3-induced hyperalgesia in mice luteinizing hormon...

Neuropeptide FF1 and FF2 receptors (NPFF1-R and NPFF2-R), and their endogenous ligand NPFF, are one of only several systems responsible for mediating opioid-induced hyperalgesia, tolerance, and dependence. Currently, no small molecules displaying good affinity or selectivity for either subtype have been reported, to decipher the role of NPFF2-R as it relates to opioid-mediated analgesia, for fu...

The aim ofthis study was to examine whether f3-carotene protects against the immunosuppression seen with long-wave ultraviolet-light (UV-A) exposure. Free-living, healthy men, aged 19-39 y received 30 mg fl-carotene/d or a placebo while on a single-menu, low-carotenoid diet. After 28 d all subjects received 1 2 exposures to a UV-A/B light source over a 16d period. The total UV-A dose received r...

Previous work in our lab established that FF1b and FF1c are homologues of mammalian SF-1 and LRH in zebrafish. SF-1 was previously shown to interact with WT1 (Whim’s tumor 1) and SOX9 (SRY HMG box related gene 9) in regulation of the male sex determination pathway whereas LRH was shown to interact specifically with SHP (Small Heterodimer Partner). In this study, results of LexA yeast two-hybrid...
