MATERIAL AND METHODS: One hundred and twenty freshly-extracted human teeth were divided into four groups according to how the buccal surface to be bonded had been pre-conditioned: 1) acid-etched with 37% phosphoric acid, 2) sand-blasted with 50 microns aluminum-oxide, 3) matted with diamond burr, and 4) intact enamel used as control. Orthodontic metal brackets were bonded to the teeth using the same composite resin (Transbond XT) and self-etching primer (Transbond Plus Self-Etching Primer). Brackets were debonded within 6 hours or after thermal cycling for 2500 times (5 degrees C--37 degrees C--55 degrees C). Shear bond strength was measured on a testing machine at a crosshead speed of 3 mm/min. The bracket-failure interface was quantified according to the modified adhesive remnant index score (ARI). Data were analyzed using the two-way ANOVA test, Scheffe confidence interval of differences of means, and the chi-square test (p < 0.05). RESULTS: All the pre-conditioned groups showed significantly higher shear bond strength before and after thermal cycling than the control group. There was no significant correlation between thermal cycling and shear bond strength. The ARI scores revealed that the bond failed primarily on the adhesive-enamel interface in all groups before and after thermal cycling, with the exception of the acid-etched group, whose bonds failed mainly on the adhesive-bracket interface after thermal cycling. CONCLUSION: The authors recommend that the enamel be preconditioned before applying the self-etching primer when greater shear bond strength is desired.

In this method, no specific holder, such as the needle tip of microsyringe and the hollow fiber, is required for supporting the organic microdrop due to the using of organic solvent with low density and proper melting point. Furthermore, the extractant droplet can be collected easily by solidifying it in the lower temperature. 1-Dodecanol was chosen as extraction solvent in this work. A series of parameters that influence extraction were investigated systematically. Under optimal conditions, enrichment factors (EFs) for PAHs were in the range of 88-118. The limit of detections (LODs) for naphthalene, diphenyl, acenaphthene, anthracene and fluoranthene were 0.045, 0.86, 0.071, 1.1 and 0.66ngmL(-1), respectively. Good reproducibility and recovery of the method were also obtained. Compared with the traditional liquid-phase microextraction (LPME) and dispersive liquid-liquid microextraction (DLLME) methods, the proposed method obtained about 2 times higher enrichment factor than those in LPME. Moreover, the solidification of floating organic solvent facilitated the phase transfer. And most importantly, it avoided using high-density and toxic solvent in the traditional DLLME method. The proposed method was successfully applied to determinate PAHs in the environmental water samples. The simple and low-cost method provides an alternative method for the analysis of non-polar compounds in complex environmental water.

It is not clear whether or not diabetes produces an increase in bone mineral density or an increase in fracture rates. OBJECTIVE: The main objective of this study was to investigate whether type 2 DM produces a higher prevalence of vertebral, hip and non-vertebral fractures in obese postmenopausal Caucasian women. A secondary objective was to study the influence of DM in quantitative ultrasound measurements of the heel (QUS) and bone mineral density (BMD) measured by dual X-ray absorptiometry (DXA), in both lumbar spine (L2-L4) and proximal femur. METHOD: This study was a prospective cohort of 111 patients with type 2 DM and 91 control individuals (CTR) over age 65 and obese, recruited from 16 centers in Spain. MAIN OUTCOME MEASURES: Lateral dorsal and lumbar X-rays were performed to assess vertebral fractures. Hip and non-vertebral fractures were noted from medical records, written reports or Xray studies. QUS measurements were made of the calcaneus and BMD measurements of the lumbar spine (L2-L4) and proximal femur. RESULTS: Patients had higher BMD in the lumbar spine (L2-L4) than controls (0.979 g/cm2 vs 0.927 g/cm2, p=0.035), but we found no statistically significant differences in the proximal femur. QUS measurements showed similar values in both groups: BUA (69.3 dB/Mhz vs 66.7 dB/Mhz, p=0.291), SOS (1537 m/sg vs 1532 m/sg, p=0.249) and QUI (87.5 vs 83.7, p=0.153). No statistically significant differences were found in any case. There was no association between vertebral, hip and non-vertebral fractures and DM. The crude odds ratio, without adjusting was 1.045 (CI 95% 0.531 ; 2.059), and the adjusted odds ratio was 0.927 (CI 95% 0.461 ; 1.863). CONCLUSIONS: In obese postmenopausal Caucasian women, type 2 DM produces an increase in BMD of the lumbar spine without changes in BMD of the proximal femur or in QUS measurements of the heel. The prevalence of vertebral, hip and non-vertebral fractures did not increase in type 2 DM.

These compounds were included in the US Environmental Protection Agency's Priority Pollutants list. Direct hot water HS-SPME extraction and sonication organic extraction followed by HS-SPME were optimized using experimental designs. The first method was chosen for PAH determination. The validation of the proposed method was carried out by analyzing PAHs in the certified soil reference material RTC-CRM 123. The accuracy obtained for the PAHs was shown to be inside the prediction interval with the certified material. The optimized method was applied to the analysis of several superficial soils from Gipuzkoa (Basque Country, North Spain).

DESIGN: Population-based prospective cohort study with 7 years' follow-up. SETTING: Self-administered questionnaires and school nurses' visits. PARTICIPANTS: A total of 2922 children of both sexes and mean age 11.6 years at recruitment, resident in the Stockholm region, Sweden. MEASUREMENTS: Tobacco use was self-reported at baseline and on six subsequent surveys. Subjects' height and weight were measured by school nurses during the first 4 years, self-reported thereafter. Overweight perception was self-reported at the age of 15 years. FINDINGS: Overweight and perception of overweight were not associated with subsequent uptake of either smoking or snus among males. Among females, overweight at baseline was associated with uptake of smoking [adjusted hazard ratio (HR) 1.34, 95% confidence interval (CI) 1.09-1.63], but not of snus. A similar pattern was found with overweight status during follow-up. Among girls with low-educated parents, overweight at baseline predicted the uptake of both snus and smoking. Among 15-year-old females who never used tobacco perceived overweight was associated with subsequent uptake of smoking (adjusted HR 1.71, 95% CI 1.20-2.46), but not of snus. CONCLUSIONS: In Sweden, adolescent girls with actual or perceived overweight are at increased risk to start smoking, while indications that this increased risk applies to smokeless tobacco (snus) are limited to girls of low socio-economic status.

METHOD AND MATERIALS: A cross-sectional study was conducted among patients who were specifically referred to the Dental Teaching Clinic in Irbid, Jordan for periodontal treatment. Self-administered questionnaire related to socio-demographic data and smoking habits was completed. The oral hygiene, gingival status, periodontal health and dental status of the participants was determined by using the plaque index of Silness and Loe [Acta Odontol Scand, 22 (1964), 121], the gingival index of Loe and Silness [Acta Odontol Scand, 21 (1963), 233], clinical attachment level (CAL) and decayed, missing and filled teeth (DMFT) index respectively. RESULT: The prevalence of smoking was greater in chronic periodontitis (CP) group (44.2%) than in either chronic gingivitis (CG) (27.4%) or AgP (29.9%) group. Self-reported perio-diseases in the close family was more prevalent (77%) among subjects diagnosed with AgP. The mean plaque scores were significantly higher for smoker than non-smoker in AgP group only (P = 0.04), with significantly greater plaque and gingival scores in CG and CP groups than AgP group (P = 0.012, 0.004). A significantly greater mean gingival scores were noted among CG and CP groups than AgP group (P = 0.004). The mean CAL was higher in smokers than in non-smokers in the three groups, with statistically significant differences in CP and AgP groups (P = 0.04, 0.01 respectively).The mean number of DMFT was significantly higher in smoker than in non-smoker of all age groups (P = 0.016, 0.043 and 0.01). However, mean DMFT was significantly greater in CP and CG than AgP groups. CONCLUSION: It was concluded that (i) higher plaque and gingival index among smokers in all groups; (ii) significant difference in the CAL between smoker and non-smoke in CP and AgP groups; (iii) significant increase in caries risk among smokers in all groups; (iv) smokers and non-smokers of AgP group had significantly lower mean DMFT scores than those of CG or CP groups.

Although many studies have examined the root responses to local N and P enrichments in the soil, less research was conducted on root responses to Mg patches. New roots of pre-grown Mg-insufficient and Mg-sufficient plants of Norway spruce (Picea abies [L.] Karst.) and Scots pine (Pinus sylvestris L.) seedlings were allowed to grow into four other pots of equal size, which were placed under the tree-bearing pot. Soils in the lower pots were either unfertilised, or supplied with Mg, or NPK or a mixture of NPKMg sources. Plants were harvested after 9 months of growth. Compared to the corresponding controls (Mg versus unfertilised and NPKMg versus NPK), Mg additions did not have a significant effect on either root dry matter, total root length (TRL) or specific root length (SRL), irrespective of tree species and plant Mg nutritional status. In contrast, NPK and NPKMg additions significantly increased the root dry matter and TRL in the nutrient-rich soil patch, and decreased SRL in Norway spruce. However, the observed root morphological changes did not occur in Scots pine. Root Mg concentrations were increased in Mg-rich soil patches, but those accumulations varied with tree species. Mg accumulation in a marked patch was measured only in newly grown roots of Mg-sufficient Norway spruce, whereas a more homogenous distribution of Mg concentration was observed for all newly grown roots in Mg-insufficient trees in the four soil treatments. In Scots pine, Mg accumulations occurred in both Mg-insufficient and Mg-sufficient plants. These results suggest that Mg patches in the soil may not lead to a local increase in root growth, but to Mg uptake and root Mg accumulation. Tree roots react differently to Mg patches in comparison to their response to N or P patches in the soil.

METHODS: Eighty freshly extracted maxillary premolars were randomly divided into 4 groups (20 in each group). In all groups, the teeth were etched with 37% phosphoric acid for 20 seconds, and RMGIC (Fuji Ortho LC, GC Europe, Leuven, Belgium) was used for bracket bonding. In groups 1 and 3, the brackets were bonded directly to etched enamel surfaces; in groups 2 and 4, the etched enamel was covered with HFLCS (Pro Seal, Reliance Orthodontic Products, Itasca, Ill). Groups 1 and 2 received metal brackets, and groups 3 and 4 had ceramic brackets. The specimens were stored in distilled water at room temperature for 24 hours and subsequently tested in shear mode with a universal testing machine. After debonding, the teeth and the brackets were examined under a stereomicroscope (model SMZ-1B, Nikon, Osaka, Japan) at 20-times magnification to assess the residual adhesive on the tooth surfaces. RESULTS: Interaction between HFLCS and bracket type was not statistically significant (P = 0.15). Pretreatment with HFLCS did not cause a statistically significant change in the shear bond values of either metal or ceramic brackets (P = 0.38). Shear bond values of the ceramic brackets were higher than those of the metal brackets independent of HFLCS application (P <0.001). No significant differences were found in bond failure modes in the 4 groups. CONCLUSIONS: HFLCS application on enamel etched with 37% phosphoric acid did not affect the bond strength values and the bond failure modes of metal and ceramic brackets bonded with RMGIC. RESULTS: Interaction between HFLCS and bracket type was not statistically significant (P = 0.15). Pretreatment with HFLCS did not cause a statistically significant change in the shear bond values of either metal or ceramic brackets (P = 0.38). Shear bond values of the ceramic brackets were higher than those of the metal brackets independent of HFLCS application (P <0.001).

Using the terms 'Barrett's esophagus' and 'Barrett's esophagus, China' as key words, literatures published in Chinese and English journals were searched in Chinese data banks, as well as PubMed and ISI Web of Science from 1989 to 2007. An analysis was carried out with the standard inclusion and exclusion criteria. A total of 4120 cases were included in this study. BE was found in 2.44% of patients undergoing endoscopy for various symptoms of upper gastrointestinal tract diseases; the male : female ratio was 2.09 : 1, the average age of detection of BE was 53.15 years old, and 51% of patients with BE had typical symptoms for gastroesophageal reflux disease (GERD). The island-type BE was predominant (56.80%), and the occurrence of BE with special intestinal metaplasia (SIM) was 36.58%, but SIM was more common in tongue-type BE than island-type and circumferential-type BE (both P < 0.001), as well as in long segment BE (LSBE) than in short segment BE (SSBE) (P < 0.001). A total of 46.39% of patients had Helicobacter pylori infection. The mean length of follow up was 2 years in 492 patients. The incidence of adenocarcinoma was 0.61% patient-years of total follow up. In China, the endoscopic prevalence of BE is lower, but the average age of diagnosis is younger; a high proportion of H. pylori infection is found in patients with BE, and about half of the patients have no typical symptoms of GERD; the tongue-type BE and the LSBE are apt to SIM.

But does he really read it? Every year all over the world one million people try to stop smoking, but only for a few percent this attempt is successful. Giving up the habit of smoking is hard because it leads to biological and psychogenic addiction. The aim of this paper was to check which factors most motivated smokers to stop smoking? 50 active smokers, among them 5 former smokers, who have smoked at least 15 cigarettes a day for 15 years were classified to the preliminary study. Among them there were 23 women, which is 46% of the subjects and 27 men, which is 54% of the subjects. The average number of smoked cigarettes among present smokers was 18.4 pieces, and the former smokers smoked the average of 19 pieces daily. Present smokers smoke 8 years longer, i.e. 26.3 years than former smokers. Inscription placed on cigarette packages concerning the loss of health definitely influence smokers to make another attempt to stop smoking. This important concerns the appearance of lung cancer, the differences were statistically significant between former and present smokers (p < 0.03), women are afraid of lung cancer twice more often than men (p<0.02), also women more often were afraid of cardiovascular system diseases (chi2 = 2.013, p < 0.03) and painful death (chi2 = 7.729, p < 0.006). Over 80% of smokers declared that the raise of the price of cigarette package has a significant influence on further attempt to stop smoking. Among the subjects 20% declared that ad spots on TV positively influence giving up smoking. Other factors such as: chewing gum (only 11.1% willing to try again), tablets (only 8.9%), appearing cough (2.2%), unpleasant tobacco smell (2.2%), the loss of taste (0.0%), the improvement of life comfort (4.4%) at minimum extent motivated smokers to stop smoking. Unsuccessful attempt of giving up smoking should not discourage any smoker no his doctor to further fight for his health. In another attempt the arguments that most motivate the smoker to stop smoking are worth using again.
