Explanations for such accidents have included single consideration of the role of poor sleep and negative psychological trait and state variables. In this study, we examined whether and to what extent sleep, general health, and aggression can concomitantly predict driving behavior. Methods: A total of 360 male traffic offenders (driving under substance use; mean age: 31years) participated in this study. They completed the questionnaires covering sociodemographic, sleep-related, and behavior-related variables. In addition, their visual and acoustic reaction times were objectively tested. Results: Poor sleep, poor general health, and higher aggression scores were associated with self-rated poor driving behavior. Poor sleep was directly associated with poor driving behavior and indirectly via poor general health and aggression. In contrast, visual and acoustic reaction times were unrelated to sleep, general health, aggression, or self-rated driving behavior. Conclusion: To our knowledge, this is the first study in Iran to assess concomitantly poor sleep, poor general health, and higher aggression scores as independent predictors of poor driving behavior among a larger sample of substance-abusing traffic offenders. Furthermore, visual and acoustic reaction times were unrelated to sleep, general health, aggression, and driving behavior. Finally, importantly, poor sleep predicted both directly and indirectly poor driving behavior. Keywords: driving behavior, sleep, aggression, general health, reaction time

Abstract

BACKGROUND: Stomach cancer is a major health problem in many countries. Understanding the current burden of stomach cancer and the differential trends across various locations is essential for formulating effective preventive strategies. We report on the incidence, mortality, and disability-adjusted life-years (DALYs) due to stomach cancer in 195 countries and territories from 21 regions between 1990 and 2017. METHODS: Estimates from GBD 2017 were used to analyse the incidence, mortality, and DALYs due to stomach cancer at the global, regional, and national levels. The rates were standardised to the GBD world population and reported per 100 000 population as age-standardised incidence rates, age-standardised death rates, and age-standardised DALY rates. All estimates were generated with 95% uncertainty intervals (UIs). FINDINGS: In 2017, more than 1·22 million (95% UI 1·19-1·25) incident cases of stomach cancer occurred worldwide, and nearly 865 000 people (848 000-885 000) died of stomach cancer, contributing to 19·1 million (18·7-19·6) DALYs. The highest age-standardised incidence rates in 2017 were seen in the high-income Asia Pacific (29·5, 28·2-31·0 per 100 000 population) and east Asia (28·6, 27·3-30·0 per 100 000 population) regions, with nearly half of the global incident cases occurring in China. Compared with 1990, in 2017 more than 356 000 more incident cases of stomach cancer were estimated, leading to nearly 96 000 more deaths. Despite the increase in absolute numbers, the worldwide age-standardised rates of stomach cancer (incidence, deaths, and DALYs) have declined since 1990. The drop in the disease burden was associated with improved Socio-demographic Index. Globally, 38·2% (21·1-57·8) of the age-standardised DALYs were attributable to high-sodium diet in both sexes combined, and 24·5% (20·0-28·9) of the age-standardised DALYs were attributable to smoking in males. INTERPRETATION: Our findings provide insight into the changing burden of stomach canc

Abstract

The infrared (IR) spectra of [H.sub.2]O + NO, HDO + NO, and [D.sub.2]O + NO, isolated in solid neon at low temperature is investigated by neon matrix-isolation method combined with IR absorption spectroscopy. The structure of the second observed 1:1 [H.sub.2]O-NO complex has resulted from columbic attractions between water and nitric oxide and it could be stabilized only in matrix, probably by interaction between NO, water and [(Ne).sub.n].

Abstract

The infrared spectra of the CH3Cl:NO complex isolated in solid neon are investigated detecting most of the vibrational modes of the complex and on the basis of DFT calculations, different geometries are explored for the complex. The weak interaction between NO and CH3CI in CH3Cl:NO is responsible for small shifts of the vibrational mode frequencies of both CH3CI and NO molecules and the most stable structure is of C1 symmetry.

Abstract

The growing importance of secondary bonded complexes in modern coordination chemistry has given rise to an abundant literature in both experimental and theoretical coordination chemistry. We recently proposed an unified chemical model of secondary interaction enabling to understand the structures in terms of simple chemical rules and concepts. For some complexes the stoichiometry of the electrophilic moiety makes isomerism possible. The problems of isomerism and of the interconversion of isomers are addressed in the present. It is shown, that the reaction mechanisms discussed for pentacoordinated phosphorus derivatives are not suitable for complexes bound by a secondary interaction. The possibility of Berry's pseudo rotations is rejected for this class of systems. [ABSTRACT FROM AUTHOR]

Abstract

A study of the infrared spectra of nickel mononitrosyl complexes that were isolated in solid argon indicates the presence of two isomeric forms of NiNO. One has an end-on bent geometry, while the other has a cyclic structure, in which the NO ligand is more perturbed. Moreover, results of the density functional calculations of the structures and vibrational spectra of the two forms were in good agreement with the experimental values.

Abstract

Background: Transforming growth factor (TGF)-beta 2 signaling pathways and their receptors exert a pivotal role in behavior and fate of tumor cells. Therefore, these pathways are target of drug discovery researches. In this study, we evaluated the effects of the aqueous extract of Trachyspermum copticum (L.) link (carum) seeds on TGF-beta receptor 1 and 2 genes coding the heterodimer complex of receptor in MCF-7 cell line of human breast cancer. Methods: Non-cytotoxic concentrations of the extract determined by 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium bromide (MTT) test and cells treated with non-cytotoxic concentrations (5 and 40 µg/ml) of extract for 24 hours. Then, to evaluate the expression of TGF-beta receptors 1 and 2 genes at the level of transcription, real-time polymerase chain reaction (PCR) was performed (comparing the control group). Data were analyzed using REST® software and analysis of variance test. Level of significance was set at 0.05. Findings: Cells treated with concentration of 5 µg/ml of extract showed reduction in gene transcription levels to almost half (0.52) (P = 0.015); and in cells treated with concentration of 40 µg/ml of extract, gene transcription levels increased to 1.34 times (P = 0.066) comparing to control group. Treatment of cells with extract showed no meaningful changes in TGF-beta receptor 2 gene expression at the level of transcription (P = 0.148). Conclusion: Results suggest that treatment of MCF-7 cells with low concentration of aqueous extract of Trachyspermum copticum (L.) link seeds can affect the TGF-beta receptor 1 gene transcription, but not the TGF-beta receptor 2; and alter the microenvironment of tumor cell. Further studies have to be performed for conclusive evidence.

Abstract

The formation of Pd2N2 from the cocondensation of effusive beams of Pd and N2 in neon and argon matrices is evidenced by absorptions in the range of 2200–1800 cm-1. In argon, selective irradiation in the near-infrared and visible ranges leads to interconversions between three structures, distinguished by the stretching frequency of the diatomic N2: Bridged T-shaped (νNN at 1990 cm-1), side on (νNN at 2178 cm-1) and parallel (νNN at 1823 cm-1). For the first two structures, the νNN mode is also accompanied by another signal below 500 cm-1. An extra feature close to 490 cm-1, not sensitive to irradiation at λirr>400 nm and also assignable to a molecule with the same Pd:N2 stoichiometry (2:1), corresponds to a centrosymmetrical Pd–N–N–Pd structure with an inactive νNN mode close to 2141 cm-1, as deduced from the observation of a weak signal close to 2630 cm-1 associated with this species and assignable to the combination νNN+νPdN. All these experimental data and their structural implications are fully supported by theoretical calculations [density functional theory (DFT)]. On the basis of this comparative study, we have obtained a reliable theoretical description of the spectroscopic data using the metageneralized gradient approximation functional within the unrestricted DFT (UDFT) formalism for all spin multiplets. We have also searched a stable electronic solution for each multiplet (particularly for the singlet state), in order to account for the nondynamic correlations. [ABSTRACT FROM AUTHOR]

Abstract

For the first time the coexistence of a σ- and a π-complex in the C4H4O:HCl system has been observed, in the same supersonic expansion of a molecular jet seeded with argon (or helium) or in a flow-cooled cell at 240 K. This is an exception to the third of the Legon–Miller rules which claims the σ-structure to be the only one to exist. On the grounds of energetic considerations and band contour simulations, two observed bands at 2787.7 and 2795.5 cm-1 of the νs HCl stretching frequency are assigned to the two complexes, recorded as Fourier transform infrared spectra with a resolution between 0.2 and 0.5 cm-1. Complementary calculations show that the use of the standard second-order Mo\ller–Plesset perturbation theory may be erroneous for such a complex, due of the overestimation of the dispersion contribution with respect to the electrostatic term. It is finally established that only a balanced version of the second-order Mo\ller–Plesset perturbation method, spin-component scaled-MP2, or a higher level of theory like a coupled-cluster approach, can provide a reliable energetic analysis for this complex.

Abstract

Three gas-phase diatomic trications Se23+, Te23+, and LaF3+ have been produced by Ar+ ion beam sputtering of Se, Te, and LaF3 surfaces, respectively. These exotic molecular ions were detected at noninteger m/z values in a magnetic sector mass spectrometer for ion flight times of >=13 μs that correspond to lower limits of their respective lifetimes. Se23+ and Te23+ were unambiguously identified by their characteristic isotopic abundances. Ab initio calculations of the electronic structures of Se23+, Te23+, and LaF3+ show that these molecular trications are metastable with respect to dissociation into fragment ions of Se2++Se+, Te2++Te+, and La2++F+, respectively. Their barrier heights are about 0.49, 0.29, and 0.53 eV, and the equilibrium internuclear distances (bond lengths) are about 0.23, 0.27, and 0.26 nm, respectively. The gas-phase diatomic dications Se22+ and Te22+ were also observed and unambiguously identified. They were found to be long-lived metastable molecules as well, whereas LaF2+ is thermochemically stable. © 2004 American Institute of Physics. [ABSTRACT FROM AUTHOR]

Abstract

Background: Nutrition is an important factor in plant growth and phytochemical compound. Application of natural fertilizers in medicinal plants production can improve their yield and medicinal indices. Objective: This study investigated the possibility of substituting chemical fertalizers by biofertalizer (Nitroxin, biophosPhorus and bioSulfur) in purple coneflower production. We compared vegetative yield and total phenolic compounds of purple coneflower in response to biofertalizers and chemical nitrogen. Methods: Experiment was conducted at field of Tarbiat Modares University on 2009-2010 growing seasons using a RCBD with three replications. Twelve experimental treatments included: chemical nitrogen as urea (C), biosulfur (S), biophosphorus (P) nitroxin(N), urea+biosulfur(CS), urea+biophosphorus(CP), urea+nitroxin(CN), biophosphorus+biosulfur(PS), Nitroxin+biosulfur(NS), nitroxin + biophosphorus(NP), integration of three biofertilizers (NPS) and the control (without fertalizers). Results: Treatments had significant effect (p≤ 0.05) on the number of lateral branches, number of flowers, diameter of flower, stem and root, plant height, root length, dry biological yeild, harvest index, plant nitrogen and phosphor content. NP treatment produced maximum leaf dry weight, biological yield, root length, root and stem diameter and number of lateral branches. Conclusion: Biofertilizers improved yield of purple coneflower. The NP treatment could be introduced as a superior treatment in quantitative traits. Also the PS treatment with the highest yield of root phenolic compound (%116 more than control) could be identified as the best nutritional system for quality. Therfore biofertilisers application can decrease the chemical fertilizer consumption and can bring us closer to the goals of sustainable agriculture.

Abstract

Objective(s) Isoniazid (INH) is one of the main first line drugs used in treatment of tuberculosis and development of resistance against this compound can result in serious problems in treatment procedures. Resistance to INH is mediated mainly by mutation in KatG gene that is coded for the catalase enzyme. The proportional method for detection of INH-resistance is time consuming due to the slow growth rate of Mycobacterium tuberculosis. In this study, we used PCR-RFLP approach for screening of common mutations in KatG gene for detection of INH resistance, and compared the results to minimal inhibitory concentration (MIC) in M. tuberculosis isolates. Materials and Methods Fifty M. tuberculosis isolates were subjected to study of which, 25 strains were INH-resistant and 25 strains were INH-sensitive. Results Of 25 INH-resistant strains, the mutation was identified in 56% and 20% in the KatG315 and KatG463 loci, respectively. In 24% of INH-resistant strains, no mutation was observed in the studied loci. INH MIC was

Skull base meningiomas comprise s major part of brain meningiomas. They are difficult to treat because of proximity to major vital neuro-vascular structures which makes their surgical resection hazardous and fraught with a high rate of complications. Radiosurgery is considered as an alternative efficient way to treat them, which targets the tumor and its supplying vasculature. The standard treatment consists of tumor eradication and its supplying vessels through homogeneous dose of 201 rays of cobalt 60 source."n"nMethods: In a case-series study, we report 230 meningiomas referred to Iraninan Gamma Knife Center, treated by radiosurgery with type C Gamma Knife. Radio-surgery was performed at a mean dose of 15 Gy and 50% isodose."n"nResults: Two hundred and thirty of all meningioma cases refered to our institute were skull base lesions. Eighty (35%) were new case and the rest were previously treated microsurgically one or more times. None of the patients died after treatment and the most common post-operative complications were headache (30 patients) and peri-tumoral edema (12 patients)."n"nConclusion: Tumoral control is defined as reduced tumor volume or as no change in tumor volume. Tumor control was achieved in 218 (95%) patients. In those who were not treated microsurgically, clinical improvement was more pronounced. Thus when suitable (favorable tumor size and absence of progressive mass effect signs) the patients could be primarily treated with Gamma knife. Other patients could be managed complementarily with radiosurgery after they are treated surgically.

Abstract

Background and Objective: The aim of the study was to evaluate the clinical effects of a mouthwash containing Sage (Salvia officinalis) extracts on Streptococcus mutans (SM) causing dental plaque in school-aged children. Material and Methods: A double blind clinical trial study was conducted in a dormitory on 70 girls aged 11-14 years having the same socioeconomic and oral hygiene conditions. These students were randomly divided into 2 groups; the first group (N=35) using Sage mouthwash, and the second group (N=35) using placebo mouthwash without active any ingredients. At the baseline, plaque samples obtained from the buccal surfaces of teeth were sent to laboratory to achieve SM colony count. These tests were reevaluated after 21 days of using the mouthwashes. Statistical data analysis was performed using t-student tests with p

Abstract

Background: Discharge against Medical Advice (DAMA) is a problem for hospitals which may result in increasing readmissions, morbidities, inabilities, deaths and health care costs. This study, aimed to investigate the rate and causes of DAMA in Iranian hospitals. Methods: A systematic review and meta-analysis study was conducted in 2014. Required data were collected through searching for key words included: "Discharge Against Medical Advice", "Leaving against medical advice", "causes*", "hospital" and their Persian equivalents, over databases including PubMed, OVID, Google Scholar, Embase, Scopus, Magiran, scientific information database (SID). The reference lists of the articles, certain relevant journals and web sites in this field were also searched. Results: Out of 913 articles initially retrieved, finally 17 articles were incorporated into the study. There were 244858 individuals studied in the articles. Using a random effects model, the rate of DAMA in Iranian hospitals was estimated at 7.9% (6.3%-9.8%). While the highest rate of DAMA was associated with patients in departments of psychiatry (12%), the lowest rate was related to patients in departments of pediatrics (3.7). DAMA was in men more than women (P

Abstract

Quantum chemical calculations on the Li–C2H4 complex have been performed with coupled-cluster and density functional methods. For both methods the electronic ground state of the complex is calculated to be 2B2, with a C2v symmetry equilibrium structure, and the calculated binding energy is quite small (around 2 kcal/mol), and therefore very much basis set dependent. The vibrational spectrum has been calculated at the harmonic approximation, including 13C/12C, 7Li/6Li, and H/D isotopic substitutions. The agreement between experimental and calculated infrared frequencies is correct, except for the low frequency symmetric Li–C stretching mode. These calculations also allow to propose an assignment for the observed C–H/C–D stretching modes. The observed blue-shift of the symmetric CH2 bending mode as well as the red-shift of the antisymmetric CH2 bending, CD2 bending, and C–C stretching modes with respect to the free ethylene have been confirmed by the density functional calculations. The Na...C2H4 complex has been found to be unstable in its 2B2 electronic state. The study of the 2A1 electronic state for both Na...C2H4 and K...C2H4 complexes show that they are at most very weak van der Waals complexes. This result confirms the conclusions of matrix isolation experiments. © 1995 American Institute of Physics. [ABSTRACT FROM AUTHOR]
