lymph node (ln) metastasis is considered an important prognostic factor in patients with prostate cancer. the aim of this study was to determine the rate of ln metastasis among an iranian population who underwent radical prostatectomy (rp) with pelvic ln dissection (plnd). in a retrospective review of medical records, 450 rp cases were included and the data on ln metastasis were extracted from ...

Studiesof nuclearor atomic reactionsinvolving neon. argon, krypton, xenon, fluorine, sulfur, chlorine, nitrogen, and other elements as targets have required use of gas cells, differentially pumped chambers [l1, or compound solid targets (e.g. melamine). The large spatial extent of a gas cell target can cause severe geometrical problems, e.g . at small scattering angles where good angular resolu...

Proof. Consider the function class F = {f(·,x) | x ∈ P} as defined in (SP1), that is f(i,x) = fi(x). Since fi(·) each is assumed to be Lipschitz continuous with Lipschitz constant Li, we must have |fi(x)− fi(y)| ≤ LF ‖x− y‖, where LF ≡ max{L1, . . . , Ln}. Moreover, the index set P ∈ R for the function class F is assume to be bounded. Therefore all conditions for Lemma 2 are satisfied and hence...

Coordination-driven self-assembly of discrete nanosized molecular cages has become one of the most active areas of supramolecular chemistry.1 Over the past decade, extensive studies have been made on discrete molecular assemblies MxLy with various values of x and y.2 Among these metal-ligand clusters, the assembly of M2L4 tetragonal cage remains quite rare, although a few such d-block metal sup...

The synthesis of a new functionalised bis-macrocyclic ligand (L1) is described together with the corresponding Ln(III) complexes, Ln(2)- (Ln = Gd(III), Eu(III)). Phosphorescence measurements on Gd(2)- at 77 K allowed the ligand-centred triplet state ((3)pi-pi*) to be estimated at ca. 28500 cm(-1). Steady state and time-resolved measurements confirmed emission from the f-centred excited state ((...

For two subsetsW and V of a normed space X. The relative Kolmogorov n-width ofW relative to V in X is defined by Kn(W,V )X := inf Ln sup f∈W inf g∈V∩Ln ‖f − g‖X , where the infimum is taken over all n-dimensional subspaces Ln of X. For ∈ R+, defineW p (1 p ∞) to be the collection of 2 -periodic and continuous functions f representable as a convolution f (t)= c + (B ∗ g)(t), where g ∈ Lp(T ), T ...

This article reports the syntheses, characterization, structural description, together with magnetic and spectroscopic properties of two isostructural molecular magnets based on chiral ligand N,N′-bis((1,2-diphenyl-(pyridine-2-yl)methylene)-(R,R/S,S)-ethane-1,2-diamine), L1, general formula [Ln2(RR-L1)2(Cl6)]·MeOH·1.5H2O, (Ln = Ce (1) or Nd (2)). Multifrequency electron paramagnetic resonance (...

Six disubstituted ligands based upon 2-(2′-pyridinyl/pyrazinyl)quinoline-4-carboxylic acids have been synthesised, solvent-free, in one step from a range of commercially available isatin derivatives. These species behave as ancillary chelating for Ir(III) complexes the form [Ir(C^N)2(N^N)]PF6 (where C^N=cyclometalating ligand; N^N=2-(2′-pyridinyl/pyrazinyl)quinoline-4-carboxylic acids). An X-ra...

  Objective(s): Lupus nephritis (LN) is the main cause of mortality and disability in systemic lupus erythematosus (SLE) patients. Therefore, utilizing a reliable and non-invasive method for serial measurements of renal function seems to be necessary. The aim of this study was to evaluate the role of urinary lipocalin-2 as a biomarker of renal involvement in SLE patients.   Materi...
