On the Effectiveness of Group Cognitive-behavioral Intervention of the Spouses on the Reversion Prediction of the People in Methadone Therapy

AbstractProblem setting: Lack of the necessary skills and unsuitable relationship between spouses, are concerned as factors of continuation in addiction. This research has been done in order to define the effectiveness of group cognitive-behavioral intervention of the spouses on the reversion prediction of the people in methadone therapy. Method: 70 addicted people who had come to “Omid Desertion Center” in Iran-lahijan, were studied by DASS21, and RPS standard measures and CRQ, WRQ, CRI, and AQ questionnaires in this research. Among these people, 30 addicted subjects, who had the criterion for this study, were selected randomly and put into two groups of experimental and controlled group, each with 15 people. The experimental group was in an experiment of cognitive-behavioral intervention for 12 sessions of 90minutes. At the end, both groups were assessed by the same mentioned questionnaires one more time months, they answered to the RPS standard measure. The data were analyzed by the co-variance (ANCOVA, MANCOVA) statistical method. The results: The results showed a significant difference between the two groups in reversion prediction of the people in theory and the management of stress, anger and worry, and coping skills (problem focused) and not significant in coping skills (emotion focused) and negotiation and solving the probl ems in their spouses. Conclusion: The results of the study show that group cognitive – behavioral intervention on the spouses is an effective method for reversion prediction of the people in methadone therapy

Tinidazol antibiotic degradation in aqueous solution by zero valent iron nanoparticles and hydrogen peroxide in the presence of ultrasound radiation

The purpose of this study was to investigate the efficiency removal of the antibiotic Tinidazol by hybrid system of ultrasonic/nZVI/H₂O₂ (US/nZVI/H₂O₂) in aquatic environment. It examined the effect of variables such as concentration of antibiotic, nZVI and H₂O₂, frequency of US and pH. Also the performance of system in removal of COD and electrical energy consumed by the ultrasonic bath was investigated. Findings showed the best efficiency (93 %) for system in pH 3, concentration hydrogen peroxide of 1M, amount of 0,2 g of zero valent iron nanoparticles and 130 kHz radiation frequency. According to the results US/nZVI/H₂O₂ method can be good performance in removal of antibiotics Tinidazol and similar pollutants

Solubilization capacity of surfactant due to its different chain length of lipophile and hydrophile

The aim of the study is to look at the influence of different chain length of hydrophile and lipophile of the surfactants to their solubilization capacity. The solubilization capacity of surfactants with different chain lengths of lipophile and hydrophile has been performed by preparing somesolubilization form formulas, using several kinds of lipophilic chain length, i.e. cetyl (C-16), stearyl (C-18), and oleyl (C=18 with unsaturated chain) alcohols and ethyleneoxyde chain length of 2, 10 and 20 respectively. After preparation, the solubilited forms were then stored at temperature of 25O and 45OC, and observed if there were any solubilization occurred. The results have showed that it needs an optimum length of ethyleneoxyde to have better solubilization; at certain longer ethylenoxyde the longer the length of lipophilic chain, the more solubilization would be, therefore, unsaturated hydrocarbon chain caused diminution of solubilization; whatever the surfactant used as an agent of solubilization, storage at a higher room temperature would facilitate the solubilization to occur.Key words : surfactant, solubilizatio

Heterogeneous determinants of quality of life in different phenotypes of Parkinson's disease

Objectives Health-related quality of life (HRQoL) is considered a very important outcome indicator in patients with Parkinson's disease (PD). A broad list of motor and non-motor features have been shown to affect HRQoL in PD, however, there is a dearth of information about the complexity of interrelationships between determinants of HRQoL in different PD phenotypes. We aimed to find independent determinates and the best structural model for HRQoL, also to investigate the heterogeneity in HRQoL between PD patients with different phenotypes regarding onset-age, progression rate and dominant symptom. Methods A broad spectrum of demographic, motor and non-motor characteristics were collected in 157 idiopathic PD patients, namely comorbidity profile, nutritional status, UPDRS (total items), psychiatric symptoms (depression, anxiety), fatigue and psychosocial functioning through physical examination, validated questionnaires and scales. Structural equation model (SEM) and multivariate regressions were applied to find determinants of Parkinson's disease summary index (PDSI) and different domains of HRQoL (PDQ-39). Results Female sex, anxiety, depression and UPDRS-part II scores were the significant independent determinants of PDSI. A structural model consisting of global motor, global non-motor and co-morbidity indicator as three main components was able to predict 89 of the variance in HRQoL. In older-onset and slow-progression phenotypes, the motor domain showed smaller contribution on HRQoL and the majority of its effects were mediated through non-motor features. Comorbidity component was a significant determinant of HRQoL only among older-onset and non-tremor-dominant PD patients. Fatigue was not a significant indicator of non-motor component to affect HRQoL in rapid-progression PD. Conclusions Our findings showed outstanding heterogeneities in the pattern and determinants of HRQoL among PD phenotypes. These factors should be considered during the assessments and developing personalized interventions to improve HRQOL in PD patients with different phenotypes or prominent feature. © 2015 Fereshtehnejad et al

Two new xanthones from Artocarpus obtusus

Two new xanthones, pyranocycloartobiloxanthone A (1) and dihydroartoindonesianin C (2), were isolated from the stem bark of Artocarpus obtusus Jarrett by chromatographic separation. Their structures were determined by using spectroscopic methods and comparison with known related compounds. Pyranocycloartobiloxanthone A (1) showed strong free radical scavenging activity by using DPPH assay as well as cytotoxicity towards K562, HL-60, and MCF7 cell lines

Clinicopathological Significance of Vimentin and Cytokeratin Protein in the Genesis of Squamous Cell Carcinoma of Cervix

Cervical cancer is one of the commonest types of cancers worldwide especially in developing countries. Intermediate filaments protein family has shown a role in the diagnosis of various cancers, but a few studies are available about the vimentin and cytokeratin roles in the cervical cancer. This case control study aimed to interpret the expression of vimentin and cytokeratin proteins in the development and progression of cervical cancer and its correlation with clinicopathological features. The cytoplasmic expression of vimentin was observed in 40% of cases, but not in inflammatory lesions of cervix. It was noticed that vimentin expression was increasing significantly with high grade of the tumour. Cytokeratin expression was observed in 48.33% and it was noticed that the expression was 62.5% in well differentiated (G1), 45% in moderately differentiated (G2), and 41.66% in poorly differentiated carcinoma, yet statistically insignificant. The expression of vimentin and cytokeratin proteins was not significantly associated with age groups. The current findings concluded a possible role of vimentin in the development and progression of cervical cancer and vimentin marker will be useful in the diagnosis and grading of cervical cancer

Molecular and clinical analysis of Ellis-van Creveld syndrome in the United Arab Emirates

<p>Abstract</p> <p>Background</p> <p>Ellis-van Creveld (EvC) syndrome is an autosomal recessive chondrodysplastic condition with clinical manifestations that include short-limbs and ribs, postaxial polydactyly and dysplastic nails and teeth. In about two thirds of patients, mutations in either <it>EVC </it>or <it>EVC2 </it>genes have been found to be the underlying cause.</p> <p>Methods</p> <p>In this paper, we describe the molecular (DNA sequencing) and clinical analysis of six children diagnosed with EvC from four different families from the United Arab Emirates (UAE).</p> <p>Results</p> <p>All the children had the common clinical and radiological features of this syndrome. However, DNA sequence analysis of the genes shown to be involved (<it>EVC </it>and <it>EVC2</it>) revealed a novel splice site mutation (c.2047-1G>T) in intron 13 of <it>EVC2 </it>gene in one family. In addition, we confirm previous mutational analyses that showed a truncating mutation in exon 13 of <it>EVC </it>gene (c.1813C>T; p.Q605X) in the second family and a single nucleotide deletion (c.981delG; p.K327<it>fs</it>) in exon 8 of <it>EVC2 </it>gene in the third family. No mutations in the exons, splice sites or the promoter regions of either gene have been found in the index case of the fourth family who exhibited "EvC-like" features.</p> <p>Conclusions</p> <p>Given the small population size of UAE, our data illustrates further the molecular heterogeneity observed in EvC patients and excludes the possibility of a common founder effect for this condition in the UAE reflecting the current ethnic diversity of the country.</p

Operational experience with the GEM detector assembly lines for the CMS forward muon upgrade

The CMS Collaboration has been developing large-area triple-gas electron multiplier (GEM) detectors to be installed in the muon Endcap regions of the CMS experiment in 2019 to maintain forward muon trigger and tracking performance at the High-Luminosity upgrade of the Large Hadron Collider (LHC); 10 preproduction detectors were built at CERN to commission the first assembly line and the quality controls (QCs). These were installed in the CMS detector in early 2017 and participated in the 2017 LHC run. The collaboration has prepared several additional assembly and QC lines for distributed mass production of 160 GEM detectors at various sites worldwide. In 2017, these additional production sites have optimized construction techniques and QC procedures and validated them against common specifications by constructing additional preproduction detectors. Using the specific experience from one production site as an example, we discuss how the QCs make use of independent hardware and trained personnel to ensure fast and reliable production. Preliminary results on the construction status of CMS GEM detectors are presented with details of the assembly sites involvement

Malaria and Dengue mosquito vectors from Lao PDR show a lack of the rdl mutant allele responsible for cyclodiene insecticide resistance

The gamma-aminobutyric acid (GABA) receptor, RDL, plays important roles in neuronal signalling and is the target of highly effective insecticides. A mutation in RDL, commonly A296S, underlies resistance to several insecticides such as cyclodienes. Even though the use of cyclodienes has been banned, the occurrence of mutations substituting A296 is notably high in mosquitoes from several countries. Here we report a survey investigating the prevalence of the Rdl mutant allele in mosquitoes from Laos, a country where mosquito-borne diseases such as malaria and dengue fever are health concerns. Anopheles and Aedes mosquitoes were collected from twelve provinces in Laos. Adult bioassays on Ae. aegypti (Linnaeus) (Diptera: Culicidae) and Ae. albopictus (Skuse) showed that all the populations tested were susceptible to dieldrin (4%) following WHO protocols. Exon 7 from a total of 791 mosquitoes was sequenced to identify the amino acid encoded for at 296 of RDL. Only one of these mosquitoes, Anopheles maculatus rampae (Diptera: Culicidae) from Attapeu, carried the mutant allele being heterozygous for A296S. We therefore found a general lack of the Rdl mutant allele indicating that mosquitoes from Laos are not exposed to insecticides that act on the GABA receptor compared to mosquitoes in several other countries. Identifying the prevalence of the Rdl mutation may help inform the potential use of alternative insecticides that act on the GABA receptor should there be a need to replace pyrethroids in order to prevent/manage resistance
