Abstract Background: The purpose of this review is to systematically evaluate the effects of an essential-oil mouthwash compared to a chlorhexidine mouthwash with respect to plaque and parameters of gingival inflammation.Methods: PubMed databases were searched for studies up to and including may 2015. A comprehensive search was designed and the articles were independently screened. Articles that evaluated the effects of the essential oil mouthwash compared to chlorhexidine mouthwash were included. A meta-analysis was performed, and weighted mean differences were calculated.Results: A total of 17 unique articles were found, of which 11 articles met the eligibility criteria. A meta-analysis of long-term studies (duration > 3 months) showed that the essential oil mouthwash provided significantly better effects regarding prophylactic plaque control than chlorhexidineConclusion: In long-term use, the standardized formulation of essential oil mouthwash is more reliable than chlorhexidine mouthwash.

Abstract Background This examiner-blind, stratified, parallel study aimed to evaluate the anti-gingivitis efficacy of a non-aqueous (anhydrous) 0.454% w/w stannous fluoride toothpaste (‘Test’) versus a sodium monofluorophosphate toothpaste (‘Control’) in people with clinically-confirmed mild-moderate gingivitis. Plaque-induced gingivitis can progress to irreversible periodontitis if left untreated. This can be controlled by an effective oral hygiene regimen such as one including toothbrushing with a toothpaste containing the chemotherapeutic agent stannous fluoride. Long-term studies over 4–12 weeks have shown the efficacy of stannous fluoride; however, shorter term studies are needed to examine if the effects on measures of gingivitis and plaque control occur sooner. Methods Eligible participants were randomised to 3 weeks’ twice-daily brushing (for 1 min) with Test or Control toothpastes. The primary efficacy variable was between-treatment difference in Bleeding Index (BI) at 3 weeks; secondary variables were between-treatment differences in number of bleeding sites, modified Gingival Index (MGI), and Turesky modification of the Quigley–Hein Plaque Index (TPI) at Weeks 2 and 3. Results A statistically significant (p < 0.0001) lower BI score was reported for Test (n = 65) versus Control (n = 65) groups at Week 2 (mean difference: − 0.07 [95% CI − 0.9, − 0.05]; 32.7% difference) and Week 3 (mean difference: − 0.06 [95% CI − 0.8, − 0.04]; 29.2% difference). The Test group also demonstrated statistically significant lower (all p < 0.0001 versus Control) number of bleeding sites (Weeks 2/3 mean difference [95% CI]: − 10.04 [− 12.3, − 7.5]/ − 8.2 [− 11.1, − 5.3] sites; 33.0%/29.3% difference); MGI score (Weeks 2/3 mean difference [95% CI]: − 0.09 [− 0.13, − 0.06]/ − 0.10 [− 0.14, − 0.06]; 4.3%/4.7% difference); overall TPI score (Weeks 2/3 mean difference [95% CI]: − 0.45 [− 0.55, − 0.35/ − 0.42 [− 0.53, − 0.30] difference; 16.0%/15.1% difference) and interproximal TPI score (Weeks 2/3 mean difference [95% CI]: − 0.42 [− 0.52, − 0.30]/ − 0.41 [− 0.52, − 0.29]; 14.6%/14.1% difference). Both toothpastes were generally well tolerated. Conclusion Three weeks’ twice-daily brushing with the 0.454% w/w stannous fluoride Test toothpaste compared to the Control toothpaste led to statistically significant lower gingival bleeding, gingival inflammation and plaque levels in adults with mild-moderate gingivitis. These results indicate that plaque and gingivitis-reducing benefits of 0.454% w/w stannous fluoride may be seen from 2 weeks’ use.

The influence of the COVID-19 pandemic on human-pet interactions within New Zealand, particularly during lockdown, was investigated via two national surveys. In Survey 1, pet owners (n = 686) responded during the final week of the five-week Alert Level 4 lockdown (highest level of restrictions—April 2020), and survey 2 involved 498 respondents during July 2020 whilst at Alert Level 1 (lowest level of restrictions). During the lockdown, 54.7% of owners felt that their pets’ wellbeing was better than usual, while only 7.4% felt that it was worse. Most respondents (84.0%) could list at least one benefit of lockdown for their pets, and they noted pets were engaged with more play (61.7%) and exercise (49.7%) than pre-lockdown. Many respondents (40.3%) expressed that they were concerned about their pet’s wellbeing after lockdown, with pets missing company/attention and separation anxiety being major themes. In Survey 2, 27.9% of respondents reported that they continued to engage in increased rates of play with their pets after lockdown, however, the higher levels of pet exercise were not maintained. Just over one-third (35.9%) of owners took steps to prepare their pets to transition out of lockdown. The results indicate that pets may have enjoyed improved welfare during lockdown due to the possibility of increased human-pet interaction. The steps taken by owners to prepare animals for a return to normal life may enhance pet wellbeing long-term if maintained.

The task of precipitation nowcasting is significant in the operational weather forecast. The radar echo map extrapolation plays a vital role in this task. Recently, deep learning techniques such as Convolutional Recurrent Neural Network (ConvRNN) models have been designed to solve the task. These models, albeit performing much better than conventional optical flow based approaches, suffer from a common problem of underestimating the high echo value parts. The drawback is fatal to precipitation nowcasting, as the parts often lead to heavy rains that may cause natural disasters. In this paper, we propose a novel interaction dual attention long short-term memory (IDA-LSTM) model to address the drawback. In the method, an interaction framework is developed for the ConvRNN unit to fully exploit the short-term context information by constructing a serial of coupled convolutions on the input and hidden states. Moreover, a dual attention mechanism on channels and positions is developed to recall the forgotten information in the long term. Comprehensive experiments have been conducted on CIKM AnalytiCup 2017 data sets, and the results show the effectiveness of the IDA-LSTM in addressing the underestimation drawback. The extrapolation performance of IDA-LSTM is superior to that of the state-of-the-art methods.

AbstractESA’s X-ray Astronomy Mission, XMM, scheduled for launch in 1998, is the second of four cornerstones of ESA’s long term science program Horizon 2000. Covering the range from about 0.1 to 10 keV, it will provide a high throughput of 5000 cm2 at 7 keV with three independant telescopes, and have a spatial resolution better than 30 arcsec. Broadband spectrophotometry is provided by CCD cameras while reflection gratings provide medium resolution spectroscopy (resolving power of about 400) in the range 0.3–3 keV. Long uninterrupted observations will be made from the 24 hr period, highly eccentric orbit, reaching a sensitivity approaching 10−15 erg cm−2 s−1 in one orbit. A 30 cm UV/optical telescope is bore-sighted with the x-ray telescopes to provide simultaneous optical counterparts to the numerous serendipitous X-ray sources which will be detected during every observation.

The shell growth of small coastal Mytilus edulis L. was measured at three different constant low salinities over short periods of time. Growth was significantly depressed in 6·4 and 16‰ S but not in 22·4‰ S. Fluctuating salinities between 0 and 32‰ S depressed growth whether the fluctuations were of sinusoidal or abrupt form. After 1 week of preconditioning to constant 32‰ S the growth of coastal (Bangor) mussels was better than estuarine (Conwy) mussels. However, after two weeks’ preconditioning to 32‰ S the estuarine mussels displayed the best growth. In the fluctuating regime, both coastal and estuarine mussels exhibited poor growth rates. The long-term response of the shell growth of coastal M. edulis was followed over a period of 44 days. Salinities in the range 1·8–9·6‰ S were lethal to the mussels within 10 days. In 12·8 and 16‰ S growth was initially delayed but recovered eventually. There was a gradual decline in the growth rate of the mussels exposed to the higher salinities (19·2–32‰) and an improvement in the growth of the mussels living in lower salinities (12·8 and 16‰) to levels nearly matching that of the high salinity animals by day 37. This suggests that acclimation of the shell growth of M. edulis to salinities in the 12·8–28·8‰ S range was achieved by the mussels during the experimental period.

Objective: The goal of this manuscript was to review the existing literature in regards to esthetic options to restore pulpotomized primary molars. Study design: A pubmed literature search has been performed and all relevant studies were assessed. Results: Two laboratory, 3 restrospective and 4 prospective clinical studies were found, reviewed and analyzed. Conclusions: Based on the limited information available, we concluded that tooth colored and bonded restorations showed promising results as alternative materials to replace stainless steel crowns after pulpotomies in primary molars. Hybrid composites tend to perform better than compomers. Resin modified glass ionomer cements demonstrated excellent marginal seal and retention. More long-term follow up studies are necessary until more definitive recommendations can be made.
