#1
Juen Mei Ding, Richard A A Kanaan
OBJECTIVES: Unexplained neurological symptoms (UNS) are common presentations in neurology but there is no consensus as to what they should be called. This is important, as patient acceptance is a predictor of outcome and there is evidence that patients are unhappy with the terms used. Patient understanding of these terms may be limited, however, and, once explained, the terms may seem more or less offensive. We sought to elicit patients' views of 7 frequently used terms for UNS, and whether these changed once definitions were provided...

New neutral and zwitterionic chiral NNO-donor scorpionate ligands (1 and 2) have been designed to obtain new mononuclear and dinuclear NNO-heteroscorpionate aluminium complexes. Reaction of 1 with [AlR3] (R = Me, Et) in a 1:1 or 1:2 molar ratio afforded the neutral mononuclear alkyl complexes [AlR2(2-bpzappe)], R = Me (3), Et (4) and bimetallic complexes [{AlR2(2-bpzappe)}(µ-O){AlR3}], R = Me (5), Et (6). By reaction of complexes (36) with PhCH2Br, mononuclear and dinuclear zwitterionic aluminium complexes [AlR2(2-bbpzappe)]Br, R = Me (7), Et (8), and [{AlR2(2-bbpzappe)}(µ-O){AlR3}]Br, R = Me (9), Et (10), were synthesised...

Advances in thin film growth technologies make it possible to obtain ultra-thin perovskite oxide films and open the window for controlling novel electronic phases for use in functional nanoscale electronics, such as switches and sensors. Here, we study the thickness-dependent transport characteristics of high-quality ultrathin Nd0.9Sr0.1NiO3 (Sr-NNO) films, which were grown on LaAlO3 (0 0 1) single-crystal substrates by using pulsed laser deposition method. Thick Sr-NNO films (25 unit cells) exhibit metallic behavior with the electrical resistivity following the T ( n) (n  <  2) law corresponding to a non-Fermi liquid system, while a temperature driven metal-insulator transition (MIT) is observed with films of less than 15 unit cells...

PURPOSE: To compare the chromatic pupillary light responses (PLR) in healthy subjects with those from patients with diseases of the outer or inner retina under various stimulus conditions, and to ascertain the parameters required to optimally distinguish between disease and control groups. METHODS: Fifteen patients with retinitis pigmentosa (RP), 19 patients with optic nerve disease (ON), and 16 healthy subjects were enrolled in this prospective study. ON included optic neuritis (NNO) and non-arteritic anterior ischemic optic neuropathy (NAION)...

OBJECTIVE: To illuminate the pathophysiology of acute rhinosinusitis (ARS) with sequential monitoring of inflammatory biomarkers during an ARS episode and to clarify their diagnostic usability in bacterial ARS. STUDY DESIGN: Inception cohort study with 50 conscripts with ARS.

BACKGROUND: Primary Ciliary Dyskinesia (PCD) is rare and its features in Israel have not been described. AIMS: to assess prevalence utilizing state-of-the-art diagnostic techniques, and describe clinical features, diagnostic and management practices in Israel. METHODS: A national multicenter study from 2012 to 2013 recruited patients diagnosed or suspected of having PCD. Diagnosis was verified using: nasal Nitric Oxide (nNO); High-speed Video Microscope Analysis (HVMA); Transmission Electron Microscopy (TEM) of cilia; Immuno-fluorescence staining (IF) for ciliary proteins, and genetic analysis...

The new dinucleating redox-active ligand (L(H4) ), bearing two redox-active NNO-binding pockets linked by a 1,2,3-triazole unit, is synthetically readily accessible. Coordination to two equivalents of Pd(II) resulted in the formation of paramagnetic (S=1/2 ) dinuclear Pd complexes with a κ(2) -N,N'-bridging triazole and a single bridging chlorido or azido ligand. A combined spectroscopic, spectroelectrochemical, and computational study confirmed Robin-Day Class II mixed-valence within the redox-active ligand, with little influence of the secondary bridging anionic ligand...

This study presents the first synthesis and characterization of a new high energy compound [1,2,3,4]tetrazino[5,6-e][1,2,3,4]tetrazine 1,3,6,8-tetraoxide (TTTO). It was synthesized in ten steps from 2,2-bis(tert-butyl-NNO-azoxy)acetonitrile. The synthetic strategy was based on the sequential closure of two 1,2,3,4-tetrazine 1,3-dioxide rings by the generation of oxodiazonium ions and their intramolecular coupling with tert-butyl-NNO-azoxy groups. The TTTO structure was confirmed by single-crystal X-ray.

The study aimed to assess the effects of Sphenopalatine ganglion (SPG) acupuncture on nasal ventilation function and autonomic nervous system in health volunteers. 39 healthy subjects were randomly assigned to either active SPG acupuncture group (AA group) or sham-SPG acupuncture group (SA group). All subjects were assessed for self-reported nasal ventilation, nasal patency (nasal airway resistance (NAR) and nasal cavity volume (NCV), exhaled nasal nitric oxide (nNO), and neuropeptides (substance P(SP), vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY)) in nasal secretions at baseline, 30 minutes, 2 hours, and 24 hours after acupuncture...

Potassium carbonate-promoted coupling reactions between 3-diazoindolin-2-imines and nucleophiles were tested. By respectively applying 2-naphthalenols and 2-arylacetates as nucleophiles, 3-azoindoles and 3-hydrazonoindolin-2-imines were obtained in excellent yields. Moreover, 3-azoindol-2-amines could be used as NNO pincer ligands for boron and resulted in the formation of hexacycleborofluorides with their absorption around 580 nm in dichloromethane.

The potent and selective cyclin-dependent kinase 2 (CDK2) inhibitor NU6027 (6-cyclohexylmethoxy-5-nitroso-2,4-diaminopyrimidine) was used as the lead for the synthesis of a series of analogues in order to provide further insight into the structure-activity relationships for 2,4-diaminopyrimidine CDK2 inhibitors. Aliphatic amino substituents were introduced at position 2. The use of linear or less sterically hindered amines gave rise to compounds endowed with slightly better activity than the lead; on the other hand, the compounds were less active if a bulkier amino substituent was used...

In patients undergoing off-pump coronary artery bypass surgery (OPCAB), it is important to attenuate myocardium injury during the surgery. The present study aimed to observe the cardioprotection induced by sevoflurane induction and maintenance compared with propofol intravenous anesthesia, and to detect its potential protection against acute myocardial injury with sensitive biomarkers. In total, 36 patients undergoing OPCAB were randomly assigned into two groups, receiving sevoflurane (n=18) or propofol (n=18) as the induction and maintenance anesthetic agent...

Mononuclear Co(II), Ni(II), Cu(II) and Zn(II) complexes of an unsymmetric Schiff base ligand, 3-(-(3-(-3,5-dichloro-2-hydroxybenzylideneamino)propylimino)methyl)quinoxalin-2(1H) -one (L) were synthesized and characterized by various analytical and spectral techniques. The molar conductance values of metal complexes indicate non-electrolytic behavior of the metal complexes. The Schiff base act as tetra dentate ONNO donor ligand in Co(II), Ni(II), Zn(II) complexes and tridentate NNO donor in Cu(II) complex. Thermal stabilities of the newly synthesized compounds were determined by thermal analysis...

Recently, reduced Nasal nitric oxide (nNO) nNO levels have been reported in children with adenoidal hypertrophy predisposing to chronic nasosinusal inflammation. Given the strict anatomic and physiopathologic link between the nasopharyngeal and middle ear compartments, and considering the high prevalence of otitis prone children among those affected with chronic adenoiditis, we designed a study aimed to test any possible difference in nNO levels between non-allergic children with and without recurrent acute otitis media (RAOM) associated with chronic adenoiditis...

A potentially symmetrical NNN pyrrolido-functionalized pincer ligand, HL = 2,5-bis(phenylazo)-1H-pyrrole, reacts with [Rh(I)Cl(PPh3)3] in toluene in the presence of air, affording an emerald crystalline solid of the composition [Rh(III)(L(O))Cl(PPh3)2]. A spontaneous C-H oxyfunctionalization of the aromatic ring with atmospheric oxygen leads to phenoxido functionalized organic transformation at room temperature. X-ray diffraction and MASS spectral analyses authenticate the unsymmetrical NNO coordination of the title ligand with a dangling phenylazo moiety...
