The Effect of Optimism Training on Emotional Problems and Life Satisfaction in Patients with Myocardial Infarction
Introduction: Acute myocardial infarction (MI) is one of the leading causes of death in the developed world. The purpose of the present research was to examine the effect of optimism training on reducing emotional problems and increasing satisfaction with life (SWL) in patients with MI.Methods: This research was a quasi-experimental one with the plan of the pre-test post-test control group. The statistical population included all patients with MI 40-65 years old who were treated in Kasra hospital in Karaj in 2019. The sample was 90 patients with MI assigned to the two groups experimental and control group randomly. Data were collected using the Depression Anxiety Stress Scales-21 (DASS-21) and the satisfaction with life scale (SWLS). The data were analyzed using the methods of Univariate and multivariate analysis of covariance.Results: The result showed that optimism training significantly decreases emotional problems and increases life satisfaction in the experimental group (P<0.01).Discussion: This finding has important implications as regards the education and mental health of patients with MI. Based on the results, it is necessary to pay more attention to two variables emotional problems and SWL in the design of interventions to reduce the psychological problems of patients with MI
The Relation between Lifestyle and High-risk Behaviors in Drivers Visiting the Cargo Terminal of Yazd
Background: Drivers are more exposed to unhealthy lifestyle due to their working conditions. Therefore, the present study was aimed to investigate the relation between lifestyle and high-risk behaviors in drivers visiting the Cargo Terminal of Yazd.
Methods: This cross-sectional study was carried out in 2017 in the Cargo Terminal of Yazd. Convenience sampling was performed. Data were collected using two questionnaires, a lifestyle and a researcher-made high-risk behaviors questionnaire. Data were analyzed by independent t-test, one-way ANOVA and Logistic Regression using SPSS version 22.
Results: The results indicated that 59.3% were smokers, 44.9% hookah users, 24% drug users, and 65.3% had relation with someone other than. There was a significant correlation between lifestyle and smoking and also drug use. Income and the number of days away from family showed a significant relation with all the high-risk behaviors. Marital status had a significant relation with hookah use and the relation with their wife. Also, education had a significant relation with hookah use and drug use.
Conclusion: Conducting intervention programs to prevent the use of various tobacco products and also the use of appropriate preventive measures to prevent the transmission of sexually transmitted diseases can play an important role in improving lifestyle and reducing high-risk behaviors in drivers.

Effect of the Molecular Size of Analytes on Polydiacetylene Chromism
The pH chromism of polydiacetylenes (PDAs) is examined with respect to the molecular size and acidity of acid analytes, along with the alkyl spacer length of primary-amine-functionalized diacetylene (DA) lipids. pH turns out to be an important parameter to charge amine headgroups of PDA but a change in pH does not necessarily result in a PDA color change. The molecular size of acid analytes is identified as another factor that can produce a configurational change in PDA amine headgroups, followed by perturbation of the ene–yne conjugated backbone. In addition, the length of a flexible alkyl spacer between the amine headgroup and the amide group of the diacetylene lipids is found to strongly affect the degree of PDA chromatic transition. The longer alkyl spacer shows a smaller chromatic transition from blue to red phase. The alkyl spacer seems to provide a certain degree of freedom to the amine headgroup, thus decreasing the transfer of headgroup steric effects to the PDA backbone. These correlations found for PDA chromism are applied to the development of a system that colorimetrically detects diethyl phosphate (DEP), a degraded nerve agent simulant. PDA liposomes show a selective chromatic transition upon binding with DEP compared to other acid analytes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71360/1/adfm_201000262_sm_supplfigs.pd
ChemInform Abstract: Synthesis, Structural Aspects, and Antimicrobial Activity Investigation of Novel Macrocyclic Amide-Containing Compounds.
SYNTHESIS AND CHARACTERIZATION OF MODEL METAL-METAL COMPLEXES OF DIACETYLENES .2.
Tetrakis (trephenylphosphine) Palladium (O) [Pd(PPh(3))(4)] and cis 1,6-bis(phenyl) hexa-1,5-diyn-3-ene (PhC=C-CH=CH-C=CPh):[L] have been synthesized and characterized. Addition of the diacetylene across the metal-metal bonds of previously prepared complexes of the general formula [Cp(2)M(2)(CO)(4)] (M=Mo, W) in toluene or dichloromethane at room temperature form 1:1 and 1:2 adducts of stable complexes (a-d). The IR of these complexes shows a semi-bridging carbonyl. The simplicity of the NMR spectra of H-1 and C-13{H-1} of these complexes shows a rapid interconvertion between CO groups. In all of the complexes, the alkyne bridges the two metal atoms, forming a quasi-tetrahedral M(2)C(2) moiety. The metal d-orbitals as well as an acceptor from carbonyl group ligands, act as donors to the carbonyl *pi-acceptor orbitals in a back-bonding fashion. The metallated products have been characterized by means of analytical data, IR, H-1, C-13{H-1}NMR, and mass spectroscopy

The compounds were characterized by elemental analyses, mass, FT-IR, H-1, and C-13 NMR spectral data. The 24-membered macrocycles have well organized symmetrical structures lacking any configurational isomerism. Ion transportation was carried out with macrocycle L (1) and L (4) against Na+, K+ and Ag+ cations. It showed a high propensity of binding with soft Ag+ cation that it undergoes configurational change during complexation. This phenomenon is not observed with hard cations, but K+ ion passes through the cavity while Na+ ions are retained. The antimicrobial activities of the compounds were evaluated using the disk diffusion method in dimethyl sulfoxide as well as the minimal inhibitory concentration dilution method, against several bacteria and yeast cultures. The results were compared with those of commercial antibiotic and antifungal agents. Structure activity relationships were also discussed.Fatih University Scientific Research CentreFatih University [P50021202_Y(2363)]; Trakya UniversityTrakya University [TUBAP-2010/174]We would like to extend our gratitude to the Fatih University Scientific Research Centre (Project-P50021202_Y(2363) and the Trakya University (Grant # TUBAP-2010/174) for their financial support.

Synthesis, spectroscopic characterization and density functional studies of a bis-benzimidazole derivative and of its complexes with palladium(II) halides
FT-Raman, FT-IR and NMR spectra, vibrational assignments and density functional studies of 1,3-bis(benzimidazol-2-yl)-2-thiapropane ligand and its Zn(II) halide complexes’
1,3-bis(benzimidazol-2-yl)-2-thiapropane (L) ligand and its zinc halide ZnX2 (X = Cl, Br, I) complexes have been synthesized. The compounds were characterized using the elemental analysis, molar conductivity, FT-Raman, FT-IR (mid i.r., far i.r.), H-1 and C-13 NMR spectra, and quantum chemical calculations performed with Gaussian 03 package program set. The optimized geometries and vibrational frequencies of the ligand and [Zn(L)Cl-2] complex were calculated using the DFT/ B3LYP method with a 6-31g(d) basis set. The geometry optimization of [Zn(L)Cl-2] yields a slightly distorted tetrahedral environment around Zn ion, while the molecule clearly reveals the Cs symmetry. The molar conductivity data reveals that the complexes are neutral. The ligand is bidentate, via two of the imine nitrogen atoms in the bis-imidazole ring units, and together with the monodentate coordination of the two halides to the metal centre
