Abstract
OBJECTIVE: To evaluate tensile bond strengths of 2 dentin bonding agents containing solvents on Nd:YAG and Er,Cr:YSGG laser-etched dentin surface. METHOD AND MATERIALS: Occlusal enamel of 146 molars was removed, and exposed surfaces were ground with a diamond bur to produce bur-cut dentin surfaces. Of those teeth, 120 were assigned to 3 groups of 40 samples in which dentin was conditioned with Er,Cr:YSGG laser, Nd:YAG laser, and 37% orthophosphoric acid (control). Each group was further divided into 2 subgroups, acetone- and ethanol-containing bonding agents, and 4-mm-long x 4-mm-wide composite rods were bonded to all specimens using a Plexiglas mold. Tensile bond strength testing of 120 samples was performed at a crosshead speed of 0.5 mm/min using a 50-kgf load cell. The remaining 26 samples were examined under SEM to evaluate the adaptation/penetration of the bonding materials and the alterations in mineral content. Data were analyzed using 1-way ANOVA and Kruskal-Wallis tests; P < .05 was considered statistically significant. RESULTS: The difference between the mean tensile bond strength values obtained with bonding agents was statistically significant in the control group. The bond strength values of the acetone-containing agent in this group were found to be higher than the ethanol-containing agent (P < .001). When compared with Nd:YAG laser, bond strength values obtained with Er,Cr:YSGG laser were higher (P < .001). The bond strength values obtained in the acid-etched group were highest for both bonding agents and demonstrated statistical significance (P < .001). CONCLUSION: Although in this study laser etching is more influential than the solvent type on bond strengths of dentin bonding agents, it cannot be considered as an alternative to conventional acid etching.

Abstract
OBJECTIVES: As the bond strength of composite resin to Er,Cr:YSGG laser-irradiated dentin has not yet been evaluated, the objectives of this study were to investigate the tensile bond strength and to analyze the resin-dentin interface among bur-cut/acid-etched, Er,Cr:YSGG laser-ablated/acid-etched and Er,Cr:YSGG laser-ablated human dentin. METHODS: Crown dentin disks prepared from extracted human third permanent molars were used for the observation of surface morphological changes by scanning electron microscope (SEM). The laser energy parameters were 3.5 W and 20 Hz with water spray (air pressure level, 80%; water pressure level, maximum level). Another group of crown dentin disks were prepared for composite resin restoration and observation of resin-dentin bond interface after demineralization in 6N hydrochloric acid (HCl) for 1 min and deproteinization in 1% sodium hypochlorite solution (NaOCl) for 10 min. The tensile bond strengths of the three groups were measured by a universal testing machine at a crosshead speed of 0.5 mm/min. Fracture types at the dentin-resin interface were analyzed using the digital stereoscopic microscope and fractured surfaces of the debonded specimens were examined by SEM. RESULTS: All three groups showed that the treated surfaces were free of dentin debris and smear layer. The peritubular dentin protruded from the surrounding intertubular dentin after laser irradiation. The dentin-resin interface treated with Er,Cr:YSGG laser irradiation and acid etching demonstrated numerous resin tags converging into a bulge and then diverging again. The length of resin tags was greater than 100 microm. The tensile bond strengths of bur-cut/acid-etched, laser-ablated/acid-etched and laser-ablated human dentin were 5.37+/-1.51, 5.17+/-1.41 and 3.29+/-0.86 MPa, respectively. No statistical significance was found between the bur-cut/acid-etched and laser-ablated/acid-etched groups. The predominant fracture modes of bur-cut/acid-etched, laser-ablated/acid-etched and laser-ablated human dentin were Type 1 (50%), Type 2 (70%) and Type 1 (70%), respectively. SIGNIFICANCE: Er,Cr:YSGG laser irradiation affects adversely adhesion of resin to dentin but acid etching following laser irradiation could increase the tensile bond strength as high as that of bur-cut/acid-etched human dentin.

Abstract
STATEMENT OF PROBLEM: CAD-CAM restorative materials are popular because they have high esthetic value and short fabrication time. Unfortunately these materials are brittle and tend to fracture under heavy occlusal load. PURPOSE: The purpose of this in vitro study was to investigate the tensile bond strengths of 5 luting agents to 2 CAD-CAM restorative materials and enamel. Material and methods One hundred truncated cones, with a 3-mm diameter bonding surface and 5-mm diameter base, were fabricated with Dicor MGC (n=50) or Cerec Vitablocs Mark II (n=50) with the Cerec system. Enamel surfaces of the crowns of 100 freshly extracted noncarious, anterior teeth, stored in 0.9% saline solution with 0.25% sodium azide (NaN(3)) as disinfectant, were prepared with sandpaper disks (320-grit size) on the Buehler Variable Speed Grinder-Polisher. The bonding surfaces of the Dicor MGC or Cerec Vitablocs Mark II truncated cones from each of the 2 tests systems were airborne particle abraded, chemically etched, and cemented on the prepared enamel surface of the tooth specimens with 5 luting agents: Vita Cerec Duo Cement, EnForce, Panavia 21, C&B Metabond, and Fuji Duet. All specimens were thermocycled 1000 times, in 5 degrees C and 55 degrees C water with a dwell time of 30 seconds in each temperature. Tensile force (MPa) was applied perpendicular to the bonding surfaces of the specimens with a universal testing machine until fracture. Fracture patterns were examined with a microscope at original magnification x10. The differences in the tensile bond strengths were analyzed with the Tukey-Kramer test (alpha=.05). RESULTS: The mean tensile bond strengths of Dicor MGC bonding to enamel with luting agents in descending order in MPa were EnForce (10.12 +/- 2.25), Panavia 21 (7.28 +/- 1.77), Cerec Duo (5.32 +/- 1.65), Fuji Duet (3.73 +/- 1.78), and C&B Metabond (3.11 +/- 1.11). EnForce had a significantly higher bond strength than C&B Metabond, Fuji Duet, Cerec Duo, and Panavia 21 (P=.05). The mean tensile bond strengths of Cerec Vitablocs Mark II bonding to enamel with luting agents in descending order in MPa were as follow: Fuji Duet (11.51 +/- 2.79), EnForce (9.44 +/- 2.03), C&B Metabond (8.98 +/- 3.29), Cerec Duo (8.66 +/- 4.71), and Panavia 21 (5.10 +/- 2.49). Within this group, there was no significant difference between Fuji Duet and EnForce, but the bond strength of Fuji Duet was significantly higher than that of C&B Metabond, Panavia 21, and Cerec Duo (P=.05). The mean tensile strength of all the luting agents bonded to Cerec Vitablocs Mark II and enamel (8.74 MPa) was higher than Dicor MGC and enamel (5.91 MPa). CONCLUSION: In this in vitro study; within the Dicor MGC group, the mean bond strength of Panavia 21 with enamel was significantly higher than C&B Metabond, Panavia 21, Cerec Duo, and Fuji Duet. Within the Cerec Vitablocs Mark II group, the mean bond strength of Fuji Duet was significantly higher than C&B Metabond, Panavia 21, and Cerec Duo but was not significantly higher than EnForce.

Abstract
A model was developed that simulated photosynthesis, growth and allocation in tree seedlings. The model was parameterized with data from experiments on seedlings of sycamore (Acer pseudoplatanus L.), Sitka spruce (Picea sitchensis (Bong) Carr.) and young birch trees (Betula pendula Roth.). In these experiments, CO2 concentration ([CO2]) and nutrient addition rate were varied. Parameters quantifying nutrient uptake, translocation and starch synthesis were fitted, based on data from control treatments. Elevated [CO2] and low-nutrient treatments were then used to test the predicted response of growth and allocation against observations. The model accurately predicted total seedling growth in the elevated [CO2] treatments. A response of growth to elevated [CO2] was seen in the birch and sycamore experiments, but not in the Sitka spruce, because of photosynthetic down-regulation. Predictions of allocation were reasonably accurate in the birch and Sitka spruce experiments, but were notably poorer in the sycamore experiments, possibly because of differences in sink strength between root and shoot. In the birch and sycamore experiments, little change in allocation with elevated [CO2] was observed or predicted. This was ascribed to the relative values of K(Tc) and K(Tn), the translocation coefficients that determine the sensitivity of allocation to carbon and nitrogen uptake rates, respectively. Growth and allocation in the low-nutrient treatments were poorly predicted by the model. In Sitka spruce, it was suspected that the photosynthetic parameters measured in August 1994 had been higher earlier in the season, before nutrients became depleted. In sycamore, the discrepancies were thought to relate to differences in sink strength between root and shoot that could not be described by the model.

Abstract
INTRODUCTION: Young adults in the military are aggressively targeted by tobacco companies and are at high risk of tobacco use. Existing antismoking advertisements developed for the general population might be effective in educating young adults in the military. This study evaluated the effects of different themes of existing antismoking advertisements on perceived harm and intentions to use cigarettes and other tobacco products among Air Force trainees. METHODS: In a pretest-post-test experiment, 782 Airmen were randomised to view antismoking advertisements in 1 of 6 conditions: anti-industry, health effects+anti-industry, sexual health, secondhand smoke, environment+anti-industry or control. We assessed the effect of different conditions on changes in perceived harm and intentions to use cigarettes, electronic cigarettes, smokeless tobacco, hookah and cigarillos from pretest to post-test with multivariable linear regression models (perceived harm) and zero-inflated Poisson regression model (intentions). RESULTS: Antismoking advertisements increased perceived harm of various tobacco products and reduced intentions to use. Advertisements featuring negative effects of tobacco on health and sexual performance coupled with revealing tobacco industry manipulations had the most consistent pattern of effects on perceived harm and intentions. CONCLUSIONS: Antismoking advertisements produced for the general public might also be effective with a young adult military population and could have spillover effects on perceptions of harm and intentions to use other tobacco products besides cigarettes. Existing antismoking advertising may be a cost-effective tool to educate young adults in the military.

Abstract
The asymmetric unit of the title compound, C(8)H(20)N(+).C(4)H(5)O(5) (-).1.36H(2)O, contains two independent ion pairs, with similar conformations, and three water mol-ecules of crystallization, one water mol-ecule haing a site-occupancy factor of 0.721 (5). Intra-molecular O-Hcdots, three dots, centeredO hydrogen bonds, involving the hydr-oxy groups and an O atom of each carboxyl-ate anion, generate five-membered rings involving S(5) ring motifs. In the crystal structure, mol-ecules are linked together by water mol-ecules through four-membered O-Hcdots, three dots, centeredO-Hcdots, three dots, centeredO-H inter-actions to form one-dimensional infinite chains along the a axis. Since the mol-ecules are also linked into one-dimensional infinite chains along the b axis, mol-ecular sheets parallel to the (001) plane are created. Overall, the crystal structure is stabilized by two intra-molecular O-Hcdots, three dots, centeredO hydrogen bonds, nine inter-molecular O-Hcdots, three dots, centeredO and ten C-Hcdots, three dots, centeredO hydrogen bonds.

Abstract
BACKGROUND: Acquiring 6-min walk test (6MWT) data from patients undergoing noninvasive mechanical ventilation due to chronic hypercapnic respiratory failure is limited. We aimed to assess whether the actual 6-min walk distance (6MWD) or the percent predicted 6MWD is a better reflection of the respiratory function of patients using home noninvasive ventilation (NIV) due to chronic hypercapnic respiratory failure. METHODS: This was a cross-sectional observational study. The 6MWT was performed in subjects using home NIV. Diagnoses were grouped as COPD, obesity hypoventilation syndrome (OHS), kyphoscoliosis, and parenchymal lung disease. Sex, age, and body mass index (BMI) were used to calculate ideal 6MWD. Male: 1,140 m - (5.61 x BMI) - (6.94 x age), and subtract 153 m for the lower limit of normal. Female: 1,017 m - (6.24 x BMI) - (5.83 x age), and subtract 139 m for the lower limit of normal. The 6MWD and percent-of-predicted 6MWD were compared relative to arterial blood gas, spirometry values, and diagnosis. RESULTS: The 6MWT was performed in 144 subjects, median (IQR) age 62 y (55-71 y). The male/female ratio, median (IQR) 6MWD, and percent-of-predicted 6MWD values were: COPD 32/6, 316 m (226-390 m), and 59.4% (42.5-68.9%); OHS 24/28, 303 m (240-362 m), and 73.0% (63.0-82.0%); kyphoscoliosis 16/7, 420 m (318-462 m), and 70.5% (56.0-75.2%); and parenchymal lung disease 19/12, 333 m (273-372 m), and 67.1% (46.7-74.7%). The correlation of percent-of-predicted 6MWD with spirometry and arterial blood gas values were better than with the actual 6MWD. CONCLUSIONS: The percent-of-predicted 6MWD was better correlated with respiratory function than actual 6MWD for subjects using home NIV due to chronic hypercapnic respiratory failure with COPD, OHS, kyphoscoliosis, and parenchymal lung disease.

Abstract
The extensive use of azole antifungal agents has promoted the resistance of Candida spp to these drugs. Candida glabrata is a problematic yeast because it presents a high degree of primary or secondary resistance to fluconazole. In Brazil, C. glabrata has been less studied than other species. In this paper, we compared the activity of three major classes of antifungal agents (azoles, echinocandins and polyenes) against fluconazole-susceptible (FS) and fluconazole-resistant (FR) C. glabrata strains. Cross-resistance between fluconazole and voriconazole was remarkable. Among the antifungal agents, the echinocandins were the most effective against FS and FR C. glabrata and micafungin showed the lowest minimal inhibitory concentrations.

Abstract
OBJECTIVE: There are limited data on the acute effects of water-pipe tobacco smoking, commonly known as water-pipe smoking (WPS), on cardiopulmonary parameters. This study evaluated the acute effects of a single 30-min session of WPS on carboxyhemoglobin (COHb) levels, pulmonary function test results, vital signs, fractional exhaled nitric oxide (Feno) levels, and exhaled breath condensate (EBC) cytokine levels in volunteers in a domestic, open-air, group smoking setting. METHODS: This prospective study evaluated the above-noted outcome parameters before and after 30 min of WPS. The primary outcome parameter was the change in COHb levels. RESULTS: Forty-five volunteers (30 men, 15 women), aged 32.35 ± 15.33 years, were recruited. After one session of WPS, the COHb levels rose significantly, from 1.47% ± 0.57% (median 1.4) to 9.47% ± 5.52% (median 7.4), P < .001. Systolic and diastolic BP levels significantly increased after smoking (systolic, 119.52 ± 12.07 mm Hg vs 131.98 ± 17.8 mm Hg; diastolic, 74.84 ± 7.89 mm Hg vs 82.98 ± 12.52 mm Hg, respectively; P < .001). Heart rates increased from 80.39 ± 9.92 beats/min to 95.59 ± 17.41 beats/min, P < .001; and respiratory rates increased from 14.36 ± 1.63 breaths/min to 16.68 ± 2.24 breaths/min, P < .001. There were decreases in forced expiratory flow between 25% and 75% of FVC, peak expiratory flow rate, Feno levels, percentage of eosinophils in peripheral blood, and 8-isoprostane levels in EBC. CONCLUSIONS: This study shows that one session of WPS causes acute biologic changes that might result in marked health problems. It adds to the limited evidence that WPS is harmful and supports interventions to control the continuing global spread of WPS, especially among youth.

Abstract
CONTEXT: Waterpipe tobacco smoking (WTS) has gained popularity, but its physiologic effects have not been extensively studied: rather, studies have focused on WTS's chronic effects or have evaluated limited respiratory/cardiac parameters. OBJECTIVE: We sought to characterize in a more detailed manner the acute effects of WTS on lung function and exercise capacity. METHOD: We recruited 24 healthy WTS males. We used a pilot single-group pre-test (abstained from WTS for ≥48 h) post-test (within 0.5 h of a 45-min WTS session) design. We performed spirometry, diffusing lung capacity and time-limited CPE testing (CPET; cycloergometer; 2-min 20-Watt warm-up and 25-Watt increase every 2-min for 10 min). RESULTS: Mean age was 20.4 years; Post-WTS, the following significant changes were observed: CO level increased from 3.7 ppm to 24.4; oxygen consumption decreased (from 1.86 L/min to 1.7); baseline respiratory rate increased (from 17.7 breath/min to 19.7); forced expiratory flow over the middle half of the forced vital capacity decreased (from 5.51 L to 5.29); and perceived exertion (measured by Borg scale) at mid and peak exercise increased. Baseline resting systolic blood pressure, pulse pressure, and pulse pressure product increased post-WTS (from 118.9 mmHg to 129.2; from 45.3 mmHg to 55.6; and from 9.9 mmHg/min to 11.1 post-WTS, respectively). During exercise, a decrease in oxygen pulse was observed post-WTS (from 10.89 ml/beat to 9.97), while the heart rate-oxygen consumption relationship increased post-WTS (from 3.52 beats/ml/kg to 3.91). CONCLUSION: Acute WTS appears to induce impairment in lung function and exercise capacity. Larger studies are warranted to further characterize the nature and extent of such impairment.
