Smoking is recognized as a health problem worldwide and there is an established tobacco epidemic in Saudi Arabia as in many other countries, with tobacco users at increased risk of developing many diseases. This cross sectional study was conducted to assess the prevalence of oral mucosal, potentially malignant or malignant, lesions associated with tobacco use among a stratified cluster sample of adults in Jeddah, Saudi Arabia. A sample size of 599 was collected and each participant underwent clinical conventional oral examination and filled a questionnaire providing information on demographics, tobacco use and other relevant habits. The most common form of tobacco used was cigarette smoking (65.6 %) followed by Shisha or Moasel (38.1%), while chewing tobacco, betel nuts and gat accounted for 21-2%, 7.7%, and 5% respectively. A high prevalence (88.8%) of soft tissue lesions was found among the tobacco users examined, and a wide range of lesions were detected, about 50% having hairy tongue, 36% smoker's melanosis, 28.9% stomatitis nicotina, 27% frictional keratosis, 26.7% fissured tongue, 26% gingival or periodontal inflammation and finally 20% leukodema. Suspicious potentially malignant lesions affected 10.5% of the subjects, most prevalent being keratosis (6.3%), leukoplakia (2.3%), erythroplakia (0.7%), oral submucous fibrosis (0.5%) and lichenoid lesions (0.4%), these being associated with male gender, lower level of education, presence of diabetes and a chewing tobacco habit. It is concluded that smoking was associated with a wide range of oral mucosal lesions, those suspicious for malignancy being linked with chewable forms, indicating serious effects.

This work reports the synthesis and application of amphiphilic ionic liquid (IL) in the petroleum field. Theionic liquid was synthesized by etherification of octadecylamine with tetraethylene glycol followed byquaternization with p-toluene sulfonic acid. The chemical structure was confirmed by NMRspectroscopy. The surface activity, aggregation, adsorption, and the solubility of the ethoxylatedoctadecylammonium tosylate were investigated. The interfacial parameters between IL aqueoussolution and crude oil emulsions were determined from interfacial tension measurement. The resultsshowed the dependence of interfacial tension on the concentration, crude oil emulsion composition andchemical structure of the prepared amphiphiles. The mechanism of aggregation and adsorptionethoxylated octadecylammonium tosylate was proposed and confirmed at different interfaces. Thedemulsification and oil spill dispersion efficiencies were investigated at different amphiphileconcentrations. The performance of amphiphilic ILs revealed that their demulsification efficiencyreached 100% and the settling time required for efficient separation decreased with increment of watercontents of crude oil emulsions. Moreover, the prepared amphiphilic ILs achieved oil spill dispersionefficiency more than 80% at surfactant oil ratio (1:25).

The present work aims to reduce the water surface tension using dispersed organophilic clay minerals toincrease the adsorption water pollutants (organic and inorganic) into the clay galleries. Therefore,sodium montmorillonite (Na-MMT) was functionalized with amphphiles based on crosslinked nanogelpolymers of N-isopropylacrylamide (NIPAm), sodium 2-acrylamido-2-methylpropane sulfonate (Na-AMPS), acrylamide (AAm) and acrylamidopropyl)trimethylammonium chloride solution (APTAC) usingsurfactant free technique. The chemical interactions between nanogels and Na-MMT and their chemicalstructure were confirmed by FTIR analysis. The intercalation and exfoliation of Na-MMT were confirmedby wide-angle X-ray diffraction. The morphology of Na-MMT nanogel composites was investigated byTEM analysis. The adsorption capacities of the prepared Na-MMT nanogels for methylene blue dye,cobalt and nickel cations from water were investigated. The data indicated that the Na-MMT nanogelsreduced the surface tension of water and efficiently remove dye and metal ions from water.

In this work, PDMS films are treated with varying fluence of hydrogen ion beams (6 × 1017, 9 × 1017, and 12 × 1017 ions/cm2) for used in storage energy devices. XRD and FTIR were used to analyze the PDMS films. Furthermore, the SEM is employed to study the morphological alterations in treated PDMS films. Both XRD and FTIR result indicated that PDMS is chemically interacting after ion treatment. In addition, the dielectric parameters of PDMS films are measured using an LCR device in the frequencies 102–106 Hz. After PDMS exposed to 12 × 1017 ions/cm2, the dielectric constant of the PDMS increased from 23.4 to 44.8, and energy density increased from 1.01 × 10–4 to 1.92 × 10–4 J/m3, while the conductivity increased from 0.29 × 10–7 to 4.3 × 10–7 S/cm. Moreover, the real M′ decreased from 0.198 for PDMS to 0.165 for 6 × 1017 ions/cm2 and to 0.052 at 12 × 1017 ions/cm2, while the imaginary M″ is decreased from 0.205 to 0.155 for 6 × 1017 ions/cm2, and to 0.069 for 12 × 1017 ions/cm2. The studies indicated that the structure as well as electrical characteristics of the treated PDMS had been improved, which allowing being used these substances in different electronic instrumentations.

Background: To evaluate the effectiveness of Microlux/DL with and without toluidine blue in screening of potentially malignant and malignant oral lesions. Materials and Methods: In this diagnostic clinical trial clinical examination was carried out by two teams: 1) two oral medicine consultants, and 2) two general dentists. Participants were randomly and blindly allocated for each examining team. A total of 599 tobacco users were assessed through conventional oral examination (COE); the examination was then repeated using Microlux/DL device and toluidine blue. Biopsy of suspicious lesions was performed. Also clinicians opinions regarding the two tools were obtained. Results: The sensitivity and, specificity and positive predictive value (PVP) of Microlux/DL for visualization of suspicious premalignant lesions considering COE as a gold standard (i.e screening device) were 94.3%, 99.6% and 96.2% respectively, while they were 100%, 32.4% and 17.9% when considering biopsy as a gold standard. Moreover, Microlux/DL enhanced detection of the lesion and uncovered new lesions compared to COE, whereas it did not alter the provisional clinical diagnosis, or alter the biopsy site. On the other hand, adding toluidine blue dye did not improve the effectiveness of the Microlux/DL system. Conclusions: The Microlux/DL seems to be a promising adjunctive screening device.

Alumina-supported copper oxides catalysts were prepared using impregnation method and character-ized using XRD, SEM and BET. Catalytic activities in phenol removal from its aqueous solution (200 ppm)were studied using hydrogen peroxide as an oxidant under microwave irradiation. Effects of copper loadings, reaction temperatures (50 and 70 8C) and pH (5 and 9) were studied. The high loading samples (9–14 wt%) exhibited 97% phenol removal efficiency corresponding to 90% total organic carbon (TOC)value. Lower loading samples (1 wt%) showed significantly lower phenol removals and inferior catalyst stability. At similar levels of phenol degradations, there was higher proportion of high molecular weight products or intermediates on 14 than on 1 wt% copper/Al2O3.

Background: To evaluate the perception of cancer patients toward treatment services and influencing factors and to inquire about the use of complementary alternative medicine (CAM). Materials and Methods: Information was obtained through pre-tested structured questionnaires completed by cancer patients during treatment at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Results: Of 242 patients, 137 (64.6%) accepted to enter this study. Most were Saudi (n=93, 68%), female (n=80, 58%), educated at university (n=71, 52%), married (n=97, 72%) and with breast cancer (n=36, 26%). One-hundred (73%) patients were satisfied with the services provided; 61% were Saudi. Ninety-four (68%) respondents were satisfied with the explanation of their cancer. Twenty-eight (21.6%) patients received CAM, of them 54.0% received herbal followed by rakia (21.0%), nutritional supplements/vitamins (7.0%) and Zamam water (18.0%), with significant differences among them (p =0.004). Seven (5%) patients believed this therapy could be used alone; 34 (25%) patients believed it could be used with other treatments, regardless of whether they themselves used this therapy. Fifty-three (53%) satisfied patients felt they received enough support; 31 (58%) patients received support from family and friends; 22 (41.6%) patients received support from the health-care team. Patients who received information about their disease from their physicians and those who felt they had enough support were more satisfied. The patients who took alternative treatment were older age, mostly female and highly educated but values did not reach significance. Conclusions: We stress enhancing the educational and supportive aspects of cancer-patient services to improve their treatment satisfaction and emphasize the need for increasing the educational and awareness programs offered to these patients.
