Abstract
Introduction COVID-19 has disrupted the global health care system since March 2020. Lung cancer (LC) patients (pts) represent a vulnerable population highly affected by the pandemic. This multicenter Italian study aimed to evaluate whether the COVID-19 outbreak had an impact on access to cancer diagnosis and treatment of LC pts compared with pre-pandemic time. Methods Consecutive newly diagnosed LC pts referred to 25 Italian Oncology Departments between March and December 2020 were included. Access rate and temporal intervals between date of symptoms onset and diagnostic and therapeutic services were compared with the same period in 2019. Differences between the 2 years were analyzed using the chi-square test for categorical variables and the Mann–Whitney U test for continuous variables. Results A slight reduction (−6.9%) in newly diagnosed LC cases was observed in 2020 compared with 2019 (1523 versus 1637, P = 0.09). Newly diagnosed LC pts in 2020 were more likely to be diagnosed with stage IV disease (P < 0.01) and to be current smokers (someone who has smoked more than 100 cigarettes, including hand-rolled cigarettes, cigars, cigarillos, in their lifetime and has smoked in the last 28 days) (P < 0.01). The drop in terms of new diagnoses was greater in the lockdown period (percentage drop −12% versus −3.2%) compared with the other months included. More LC pts were referred to a low/medium volume hospital in 2020 compared with 2019 (P = 0.01). No differences emerged in terms of interval between symptoms onset and radiological diagnosis (P = 0.94), symptoms onset and cytohistological diagnosis (P = 0.92), symptoms onset and treatment start (P = 0.40), and treatment start and first radiological revaluation (P = 0.36). Conclusions Our study pointed out a reduction of new diagnoses with a shift towards higher stage at diagnosis for LC pts in 2020. Despite this, the measures adopted by Italian Oncology Departments ensured the maintenance of the diagnostic-therapeutic pathways of LC pts. The COVID-19 outbreak had an impact on access to lung cancer (LC) diagnosis and treatment. A slight reduction (−6.9%) in newly diagnosed LC cases was observed in 2020 compared with 2019. Newly diagnosed LC pts in 2020 were more likely to be diagnosed with stage IV disease. The Italian Oncology Departments ensured the maintenance of the diagnostic-therapeutic pathways of LC pts. A reverse migration from high-volume to low-volume cancer centers was noted during the pandemic.

Abstract
Two new N-salicylidene-N'-aroylhydrazines ligands have been prepared: N-4-diethylaminosalicylidene-N'-4-nitrobenzoyl-hydrazine (L(1)) and N-4-diethylaminosalicylidene-N'-4-(4-nitrophenylethylidene)-benzoyl-hydrazine (L(2)). The ligands are properly functionalized with strong electron donor-acceptor groups and are of potential interest in second-order nonlinear optics (NLO). Dimeric copper(II) and palladium(II) complexes with L(1) and L(2) have been prepared, and, starting from these, mononuclear acentric adducts with pyridine as a further ligand have been prepared and characterized. The X-ray structures of three adducts are also reported. The NLO activity of the adducts has been determined by EFISH measurements giving mubeta values up to 1500 x 10(-48) esu for an incident wavelength of 1.907 microm.

Abstract
The crystal structures of sodium 4-([4-[N,N-bis(2-hydroxyethyl)amino]phenyl]diazenyl)benzoate 3.5-hydrate, Na+*C17H18N3O4-*3.5H2O, (I), and potassium 4-([4-[N,N-bis(2-hydroxyethyl)amino]phenyl]diazenyl)benzoate dihydrate, K+*C17H18N3O4-*2H2O, (II), are described. The results indicate an octahedral coordination around sodium in (I) and a trigonal prismatic coordination around potassium in (II). In both cases, coordination around the metal cation is achieved through O atoms of the water molecules and hydroxy groups of the chromophore. The organic conjugated part of the chromophore is approximately planar in (I), while a dihedral angle of 30.7 (2) degrees between the planes of the phenyl rings is observed in (II).

Abstract
The pentapeptide Boc-Val-delta Phe-Gly-delta Phe-Val-OME, containing two dehydro-phenylalanine (delta Phe) residues, has been synthesized and its structure investigated. In the crystalline state, the molecule adopts a right-handed 3(10)-helical conformation stabilized by two intramolecular hydrogen bonds between CO of Val1 and NH of delta Phe4, and between CO of delta Phe2 and NH of Val5, respectively. NMR measurements are consistent with the presence of 3(10)-helical structures also in acetonitrile and dimethylsulphoxide solution: the distances between backbone protons estimated from NOE connectivities are in overall agreement with those observed in the solid state; the chemical shifts of the amide protons show the smaller temperature coefficients for the NHs that in solid state are involved in intramolecular hydrogen bonds. The CD spectra in acetonitrile, chloroform, methanol and dimethylsulphoxide display exciton couplets of bands corresponding to the delta Phe electronic transition at 280 nm; the sign of the bands is consistent with the presence of helical structures having a prevalent left-handed screw sense. Addition of 1,1,1,3,3,3-hexafluoro-propan-2-ol gives rise to the gradual appearance of a couplet of opposite sign, suggesting the helix reversal from left-handed sense to right-handed sense. The conformational behaviour is discussed on the basis of the specific sequence of the peptide.

Abstract
delta-Selective antagonism of [L-Tic2]-peptides, including the simple dipeptide Tyr-L-Tic-NH2, is linked to the Tyr-Tic-"recognition site". In order to gain further information on the conformational preferences of the Tyr-Tic-moiety we have undertaken a structural study of a cyclic analog, the diketopiperazine of Tyr-Tic. A conformational study of cyclo[-Tyr-Tic-], that is almost devoid of opioid activity, can also be useful to discriminate between the role of the two aromatic rings and of the basic nitrogen in determining antagonism. The structure of cyclo[-Tyr-Tic-] has been solved in a DMSO/water solution at 278 K by NMR spectroscopy and in the solid state by X-ray diffraction methods. The two informations are almost identical, with an arrangement of the aromatic rings rather different from that of the putative bioactive conformation of the parent linear dipeptide. This difference points to the importance of conformational effects and is in agreement with the hypothesis that the positive center may be not essential for antagonism.

Abstract
The crystal and molecular structure of the peptide Boc-L-Ala-delta Phe-delta Phe-NHMe, containing two consecutive dehydro-phenylalanine (delta Phe) residues, has been solved by x-ray diffraction. Two independent molecules, X and Y, are present in the crystallographic unit. Their conformation corresponds approximately to an incipient 3(10)-helix stabilized by two intramolecular hydrogen bonds. The (phi, psi) torsion angles, however, have negative and positive signs in the two molecules X and Y, respectively. Therefore, in spite of the presence of an amino acid residue of the L configuration, the two helical molecules have opposite screw senses, even though the right-handed helix is less distorted than the left-handed one in correspondence of the L-Ala residue. The CD spectra in various solvents exhibit exciton bands originating from dipole-dipole interaction between the delta Phe side chains. Addition of DMSO to the chloroform solution produces, as a first step, a strong increasing of the CD bands, which are then progressively canceled by increasing DMSO concentration. The nmr data parallel the behavior observed in the CD spectra. In CDCl3 solution, the temperature coefficients of the NH resonances are consistent with the involvement of the last two amide protons of the sequence in intramolecular hydrogen bonds, but only negligibly small nuclear Overhauser effects (NOE) are observed. Addition of 5% DMSO-d6 allows the observation of diagnostic NOEs. CD and nmr data indicate that the solid state structure is retained in solution, and are consistent with the presence of right-handed and left-handed conformers, with a prevalence of the more stable right-handed one.

Abstract
The dehydropeptide Ac-delta Phe-L-Ala-delta Phe-NH-Me, containing two dehydro-phenylalanine (delta Phe) residues, crystallizes from methanol/water in space group P2(1)2(1)2(1), with a = 12.508 (2), b = 12.746 (1) and c = 15.465 (9). In the crystalline state, the peptide chain assumes a right-handed 3(10)-helical conformation stabilized by two intramolecular hydrogen bonds, between the N-terminal acetyl group and the NH of delta Phe3, and between the CO of delta Phe1 and the NH of the C-terminal methylamide group, respectively. The two consecutive 10-membered rings formed by the hydrogen bonds have torsion angles quite close to the standard values for type III beta-bends. delta Phe1 is located in the (i + 1) position of the first beta-bend, while delta Phe2 is located in the (i + 2) position of the other beta-bend. In the crystal, the molecules are linked head to tail by intermolecular hydrogen bonds to form long helical chains. The axes of the helices are parallel to the c axis, but neighboring helices run in antiparallel directions. This crystal packing is similar to the packing motifs frequently observed in Aib-containing peptides.

Abstract
The dehydropeptide Ac-delta Phe-L-Val-delta Phe-NH-Me, containing two dehydrophenylalanine (delta Phe) residues, crystallizes from methanol/water in space group P212121, with a = 12.622 (1), b = 12.979 (1), and c = 15.733 (1) A. In the solid state, the molecular structure is characterized by the presence of two intramolecular hydrogen bonds which form two consecutive beta-bends. The (phi, psi) torsion angles of the three residues are very similar and close to the standard values of type III beta-bends, so the molecular conformation corresponds to an incipient right-handed 3(10)-helix, only slightly distorted. In the crystal, the molecules are linked by head-to-tail hydrogen bonds, thus forming continuous helical columns packed in antiparallel mode. There are no lateral hydrogen bonds; the only interactions are hydrophobic contacts between the apolar side chains of neighboring helical columns.

Abstract
To determine whether neutrophils are involved in airway hyperresponsiveness after ozone exposure, we studied the effect of neutrophil depletion by cyclophosphamide treatment on ozone-induced airway hyperresponsiveness in seven dogs. Airway responsiveness to inhaled methacholine was determined by modified Astograph (7 Hz oscillation method), and the numbers of neutrophils in the peripheral blood, total cell counts and differential cell counts in BALF were measured before and after ozone exposure, and after ozone exposure of dogs undergoing cyclophosphamide treatment. Ozone exposure was carried out for 2 hrs at an ozone level of 3.07 +/- 0.01 ppm (mean +/- SE), and cyclophosphamide (10 mg/kg) was given intravenously daily for five days starting six days before ozone exposure. There was a significant increase in airway responsiveness to inhaled methacholine after ozone exposure in the seven dogs (p less than 0.001), and the numbers of neutrophils in the peripheral blood and the neutrophil counts in BALF increased significantly after ozone exposure (p less than 0.01). After ozone exposure of dogs undergoing cyclophosphamide treatment, the numbers of neutrophils in the peripheral blood decreased significantly (p less than 0.001) and the neutrophil counts in BALF did not increase, but the airway responsiveness to inhaled methacholine increased significantly (p less than 0.01). There was no significant correlation between the degree of the increase in airway responsiveness and the degree of the increase in neutrophil counts in BALF after ozone exposure. These results suggest that neutrophil infiltration into the airway is not necessary for an increase in airway responsiveness after ozone exposure in dogs.

Abstract
The crystal and molecular structure of the pentapeptide Boc-D-Ala-delta Phe-Gly-delta Phe-D-Ala-OMe, containing two dehydrophenylalanine residues, was determined by x-ray diffraction. The molecule crystallizes in the orthorombic P2(1)2(1)2(1) space group, with a = 10.439(3), b = 15.319(3) and c = 21.099(4) A. In the solid state, the conformation of the pentapeptide is characterized by the presence of two type III' beta-turns. Thus the peptide assumes a left-handed 3(10-helical conformation, the left sense being due to the D configuration of the alanine residues. The two unsaturated residues are located in the (i + 1) position of the first beta-turn and in the (i + 2) position of the second beta-turn, respectively. In the crystal, the helical molecules are linked head to tail by hydrogen bonds. Lateral hydrogen bonds are also formed between molecules related by a twofold screw symmetry. This gives rise to a typical mode of packing characterized by infinite helical "chains,' similar to the packing found in other oligopeptides that adopt a 3(10)-helical structure.

Abstract
To determine whether 5-lipoxygenase products are involved in hyperresponsiveness induced by ozone exposure, we studied the effect of a selective 5-lipoxygenase inhibitor, AA-861 on ozone-induced airway hyperresponsiveness in six dogs. Airway responsiveness to methacholine was measured by modified Astograph (7 Hz oscillation method) before and after ozone exposure, and TxB2 in plasma and in BALF, 6-keto-PGF1 alpha in BALF, numbers of neutrophils in the peripheral blood and differential cell counts in BALF were measured before and after ozone exposure. Ozone exposure was carried out for 2 hr at an ozone level of 3.04 +/- 0.01 ppm (mean +/- SE). There was a significant increase in airway responsiveness to methacholine after ozone exposure in the six dogs (p less than 0.01), and the numbers of neutrophils in the peripheral blood and the neutrophil counts in BALF increased significantly after ozone exposure (P less than 0.01). A selective 5-lipoxygenase inhibitor, AA-861 significantly inhibited the increase of airway responsiveness to methacholine induced by ozone exposure (p less than 0.05), and furthermore, the increase in the numbers of neutrophils in the peripheral blood and the neutrophil counts in BALF after ozone exposure were significantly inhibited by pretreatment with AA-861 (p less than 0.05). There was no significant change in the levels of TxB2 in plasma or in BALF, and also no apparent change in the levels of histamine was observed in BALF after ozone exposure. The levels of 6-keto-PGF1 alpha in BALF decreased after ozone exposure, but the decrease was not significant. These results suggest that 5-lipoxygenase products play an important role in the development of airway hyperresponsiveness and in the infiltration of neutrophils into the airway after ozone exposure in dogs.

Abstract
The conformation of tolylureas has been studied by means of X-ray diffraction, NMR spectroscopy, and semiempirical quantum-mechanical calculations. The flat shape of meta and para isomers allows a good interaction with the model sites for bitter and sweet taste, respectively, whereas the ortho isomer cannot fit the sites because of the relative arrangements of the aryl and amide planes and because of poor hydrophobic interactions. The consistency of the conformational results with the sweet taste model site, previously proposed by the authors, is emphasized by the good fit of dulcine, a sweeter para-substituted arylurea.
