It is shown that every polyhedron in R3 with m edges can be guarded with at most 27 32m edge guards. The bound improves to 6m + 1 12 if the 1-skeleton of the polyhedron is connected. These are the first non-trivial upper bounds for the edge guard problem for general polyhedra in R3.

BACKGROUND Current cardiovascular magnetic resonance (CMR) methods, such as late gadolinium enhancement (LGE) and oedema imaging (T2W) used to depict myocardial ischemia, have limitations. Novel quantitative T1-mapping techniques have the potential to further characterize the components of ischemic injury. In patients with myocardial infarction (MI) we sought to investigate whether state-of the...

Background Insulin-like Growth Factor I (IGF-I) is a peptide involved in many processes the brain. Recently, we described how IGF-I modulates sleep behavior, response to stress, and its role cognition through cholinergic, orexinergic, locus coeruleus nuclei. Nonetheless, modulation of social behavior remains explored, especially during aging Alzheimer’s disease pathology. This study aims determ...

We present results from new, detailed computations of lithium production by hot bottom burning (HBB) in asymptotic giant branch (AGB) stars of intermediate mass (3.5 ≤ M ≤ 6M ). The dependence of lithium production on stellar mass, metallicity, mass loss rate, convection and overshooting are discussed. In particular, nuclear burning, turbulent mixing and convective overshooting (if any) are sel...

A series of new 1-[(2, 3-dichloroanilinomalonyl)]-3-(N-2’-cyanoethyl-N-2, 3-dichloroanilino)-5phenyl pyrazoline have been synthesized in 48 to 77% yield, by the reaction of N-cinnamoyl-N-2’cyanoethyl-2, 3-dichloroaniline with Ethyl-2-(2,3-dichloroanilido) acetohydrazide. Pyrazolines are yellow, cream and brown color solids, having high melting points. Identity of these products has been establi...

Methods and results Sequence comparison showed a comparable sequence identity of approximately 70% between the 2EF-hand pollen allergens (Timothy grass: Phl p 7; Alder: Aln g 4; Birch: Bet v 4; Turnip rape: Bra r 1; Lamb ́s quarter: Che a 3; Olive: Ole e 3) and a lower sequence identity of 44% with the 4EF-hand allergen from olive pollen (Ole e 8). While patients ́ IgE showed extensive cross-reac...

AIMS A safe total resection followed by adjuvant chemoradiotherapy should be the primary goal in the treatment of glioblastomas (GBMs) to enable patients the longest survival possible. 5-aminolevulinic acid (5-ALA)- and intraoperative MRI (iMRI)-assisted surgery, have been shown in prospective randomized trials to significantly improve the extent of resection (EOR) and subsequently survival of ...

Numbers of the form (6m+1)(12m+1)(18m+1) where all three factors are simultaneously prime are the best known examples of Carmichael numbers. In this paper we tabulate the counts of such numbers up to 10 for each n ≤ 42. We also derive a function for estimating these counts that is remarkably accurate.

This study was undertaken to survey impacts of bottom trawling on distribution and diversity of gastropods of the Bahrakan Fishing Area (BFA), of the northwestern coasts of the Persian Gulf. Gastropod samples were collected from depths of 6m and 10m at 18 randomly selected stations in three occasions, right before the opening of shrimp trawling seasonand two weeks and 3 months after the fish...

OBJECTIVES In rheumatoid arthritis (RA), low-dose glucocorticoids (GCs) demonstrate disease-modifying potential when added to DMARDs. Modified-release (MR) prednisone taken at bedtime (released 2am) is more effective than immediate-release (IR) GC taken in the morning. METHODS In an open-label observational study, 950 RA outpatients (mean age 57 ± 13 years; 75% females) treated with GCs and D...
