Published: March 2018

A multidisciplinary science experiment was performed in K-12 classrooms focusing on the interconnection of technology with geology and chemistry. The engagement and passion for science of over eight hundred students across twenty-one classrooms, utilizing a combination of hands-on activities to study the relationships between Earth and space rock studies, followed by a remote access session wherein students remotely employed the use of a scanning electron microscope (SEM) and energy-dispersive spectroscopy (EDS) to validate their findings was investigated. Participants were from predominantly low-income minority communities, with little exposure to the themes and equipment used, despite being freely available resources. Students indicated greatly increased interest in scientific practices and careers, as well as a better grasp of the content as a result of the lab and remote access coupling format.
La polysémie poétique d’anabase chez Saint-John Perse : évocations, étymologie et botanique
Authors: Peigney Jocelyne 
Published: March 2018

Quand le nom « anabase », emprunt savant au grec, est d’un usage rare dans la langue littéraire, Saint-John Perse peut donner l’exemple de la création d’une polysémie qui croise les cheminements linguistiques, la documentation botanique et l’évocation poétique. Titre et hapax, si l’on accepte d’y voir les superpositions auxquelles invite l’écriture de Saint-John Perse, le mot devient annonce de l’aventure de l’œuvre et illustration multiple du monde qu’elle constitue.

Abstract
Turmeric is traditionally used as a spice and coloring in foods. Curcumin is the primary active ingredient in the turmeric, and compelling evidence has shown that it has the ability to inhibit inflammation. However, the mechanism mediating its anti-inflammatory effects are not fully understood. We report that curcumin inhibited caspase-1 activation and IL-1β secretion through suppressing LPS priming and the inflammasome activation pathway in mouse bone marrow–derived macrophages. The inhibitory effect of curcumin on inflammasome activation was specific to the NLRP3, not to the NLRC4 or the AIM2 inflammasomes. Curcumin inhibited the NLRP3 inflammasome by preventing K+ efflux and disturbing the downstream events, including the efficient spatial arrangement of mitochondria, ASC oligomerization, and speckle formation. Reactive oxygen species, autophagy, sirtuin-2, or acetylated α-tubulin was ruled out as the mechanism by which curcumin inhibits the inflammasome. Importantly, in vivo data show that curcumin attenuated IL-1β secretion and prevented high-fat diet–induced insulin resistance in wide-type C57BL/6 mice but not in Nlrp3-deficient mice. Curcumin also repressed monosodium urate crystal–induced peritoneal inflammation in vivo. Taken together, we identified curcumin as a common NLRP3 inflammasome activation inhibitor. Our findings reveal a mechanism through which curcumin represses inflammation and suggest the potential clinical use of curcumin in NLRP3-driven diseases.
Effect of At-home and In-office Bleaching on Marginal Microleakage in Composite Resin Restorations using Two Adhesive Systems
Authors: Klein Celso A , da Silva Douglas , Reston Eduardo G , Borghetti Diana LB , Zimmer Roberto 
Published: March 2018

ABSTRACT
Aim
The aim of this study is to assess marginal microleakage of cervical cavities restored with composite resins and two different adhesive techniques subjected to at-home and in-office bleaching.

Materials and methods
In this randomized, blind laboratory experiment, 60 bovine teeth recently extracted were collected and divided into six groups (n = 10 each group). The teeth received cervical cavity preparations (2 mm × 3 mm × 1 mm) with enamel margins. Two different adhesive systems were used (Single Bond 2 and Clearfil SE Bond), in addition to composite resin (Z250). Restored teeth received two different bleaching gels (Opalescence PF and Opalescence Boost). Teeth were thermocycled and analyzed under confocal laser scanning microscopy.

Results
No significant differences were observed (p > 0.05) in microleakage scores between the two groups not subjected to bleaching nor between the four groups that received bleaching treatment (p > 0.05), regardless of the gel and adhesive system employed. However, when comparing nonbleached with bleached teeth, those not subjected to bleaching showed statistically lower marginal microleakage scores (p < 0.05). Data were statistically analyzed using the Kruskal–Wallis test followed by Student–Newman–Keuls post hoc test, with significance set at 5%.

Conclusion
Marginal microleakage in composite resin restorations is influenced by the action of bleaching agents used both at-home and in-office, regardless of the adhesive system employed (total-etch or self-etch).

Clinical significance
Both at-home and in-office bleaching agents have an influence on the adhesive interface of resin restorations, producing changes and inducing marginal leakage.

Published: March 2018

ABSTRACTAimThe present study aimed to obtain information about knowledge, execution, and attitude toward biomedical waste (BMW) and its management.Materials and methodsIn the present study, a self-administered closed-ended questionnaire was designed to conduct a cross-sectional survey. It was distributed among 614 dentists (institution associated or private practitioners) in the cities of North India. The questionnaire comprised 36 questions regarding knowledge, execution, and attitude toward BMW and its management. Frequency distribution and chi-square test along with paired t-test were used to compare the data obtained between the private practitioners and institution-associated dentists.ResultsThe study showed that 80% private practitioners were aware of the categories of BMW as compared with 100% of institution-associated dentists. However, 41% dentists associated with institution were disposing the chemical waste directly into sewer and a surprising high number of private practitioners were discarding directly without any treatment. Furthermore, regarding the mandatory maintenance of BMW records, 100% institution-associated respondents were aware, whereas only 6.5% private practitioners knew about it. Regarding BMW management not frequently being followed, 78% of private practitioners believed extra burden as the reason.ConclusionMost of the dentists had adequate knowledge regarding BMW policies and its management. Although it was being practiced in mostly all the institutes on a regular basis, the majority of private practitioners were not practicing it due to various reasons, such as financial burden, lack of availability of service, and poor attitude toward its management.Clinical significanceThere is a need to make it compulsory and organize training sessions to educate the dental personnel and to establish the importance of proper management.How to cite this articleRaghuvanshi M, Sinha S, Mohiddin G, Panda A, Dash KC, Bhuyan L.

Evaluation of the Effects of Fluoride Prophylactic Agents on Mechanical Properties of Nickel Titanium Wires using Scanning Electron Microscope
Authors: Gupta Deepika , Gupta Amit K , Gupta Ajay K , Shukla Gita 
Published: March 2018

ABSTRACT
Introduction
Orthodontic treatment these days is increasing in demand, and therefore, it is relatively imperative for the orthodontist to prescribe the use of fluoride-containing products, such as mouthwashes and gels, to help prevent dental caries and maintain healthy oral health. The aim of the study was to assess and evaluate the effects of fluoride prophylactic agents on mechanical properties of nickel titanium (NiTi) wires during orthodontic treatment using scanning electron microscope (SEM).

Materials and methods
We used the commercially available round preformed NiTi orthodontic archwire (3M company) and three different mouthwash solutions, i.e., Phos-Flur gel (1.1% sodium acidulated phosphate fluoride, APF, 0.5% w/v fluoride, pH = 5.1; Colgate Oral Pharmaceuticals) and Prevident 5000 (1.1% sodium fluoride neutral agent, 0.5% w/v fluoride, pH = 7; Colgate Oral Pharmaceuticals). All the specimens were subjected to a three-point bending test on a universal testing machine. To observe the surface morphological changes, one wire from each group was randomly selected and observed under a SEM.

Results
It was observed that there was not much difference in the values of both modulus of elasticity and yield strength obtained after loading of stress on the wires in all the three experimental conditions. A significant difference in both modulus of elasticity and yield strength was observed during unloading of stress. Further, when the surface characteristics were observed for all the specimens using SEM images, it was observed that NiTi wires treated with Phos-Flur showed large surface defects which appeared as round, pitted areas depicting corrosion, numerous white inclusions, and overall damaged surface structure of the wire as compared with the control.

Conclusion
Thus, fluoridated mouthwashes are essential to maintain good oral hygiene and decrease instance of caries in patients undergoing orthodontic treatment. The prophylactic usage of topical fluoride agents on NiTi wire seems to diminish the mechanical properties of the orthodontic wire that could significantly affect future treatment outcomes.

Clinical significance
It has been proved that fluoride mouthwashes/gels do affect the structural surface qualities and strength of wires used during the orthodontic treatment irrespective of the composition of the wires. Therefore, it is the responsibility of the clinician to prescribe these prophylactic agents carefully while keeping in mind their pH so that the overall result of the treatment may not be hampered and delayed due to change in properties of the wires used.

Assessment of Lipid Peroxidation Levels and Total Antioxidant Status in Chronic and Aggressive Periodontitis Patients: An in vivo Study
Authors: Verma Ashish , Tripathi Vivek , Singh Sahib T , Singh Chetan D , Gill Jaspreet S 
Published: March 2018

ABSTRACT
Introduction
Periodontitis is a common problem affecting a significant population of the world. For the assessment of oxidative stress of an individual, total oxidation status (TOS) and total antioxidant capacity (TAOC) are the significant biomarkers. Hence, we planned the present study to assess malondialdehyde (MDA), TOS, TAOC levels, and oxidative stress index (OSI) in generalized aggressive periodontitis (GP) and chronic periodontitis (CP) patients.

Materials and methods
The present study included assessment of 40 CP patients, 40 GP patients, and 40 healthy controls. Clinical assessment of all the subjects was done by measuring the probing depth (PD), clinical attachment (CL), gingival index (GI), gingival bleeding index (GBI), and plaque index (PI). Salivary and serum samples were taken and assessed by standard procedures as described previously in the literature. All the values were assessed and compared.

Results
Significant results were obtained while comparing all the periodontal parameters in between various study groups. Mean serum MDA levels in the CP, GP, and control group were found to be 0.68, 0.65, and 0.61 µM respectively. Statistically nonsignificant results were obtained while comparing the serum MDA levels in between the three study groups. Significant results were obtained while comparing the mean serum and salivary TOS values, TAOC values, and OSI in between various study groups.

Conclusion
In periodontitis patients, oxidative stress was significantly higher in comparison with healthy subjects.

Clinical significance
Oxidative parameters do play a significant role in the pathologic profile of periodontitis.

Published: March 2018

ABSTRACTAimPeriodontitis, a chronic infectious disease, affects most of the population at one time or the other and its expression is a combination of hosts, microbial agents, and environmental factors. Extensive literature exists for the relationship between periodontal disease and diabetes mellitus, cardiovascular diseases, and adverse pregnancy outcomes. Only a few studies performed in a limited number of patients have reported periodontal health status in chronic renal failure patients. Hence, the aim of the present study is to assess and compare the periodontal status of patients with chronic renal failure undergoing dialysis, predialysis with systemically healthy individuals.Materials and methodsA total of 90 patients were divided into three groups. Group I: 30 renal dialysis patients. Group II: 30 predialysis patients. Control group comprised 30 systemically healthy patients who formed group III. Periodontal examination was carried out using oral hygiene index-simplified (OHI-S), plaque index (PI), gingival index (GI), probing depth, and clinical attachment loss.ResultsThe results of the study showed that the periodontal status of patients with chronic renal failure undergoing dialysis (dialysis group) and patients with chronic renal failure not undergoing renal dialysis (predialysis) when compared with systemically healthy subjects showed significantly higher mean scores of OHI-S, PI, and clinical attachment loss.ConclusionThus, patients with chronic renal failure showed poor oral hygiene and higher prevalence of periodontal disease.Clinical significanceThe dental community’s awareness of implications of poor health within chronic renal failure patients should be elevated.How to cite this articleGupta R, Kumar U, Mallapragada S, Agarwal P.

Published: March 2018

Abstract
OBJECTIVE. The purpose of this study was to investigate the gender differences in psychosocial and physical outcomes in users of lower-extremity prostheses who became amputees after the 2010 earthquake in Haiti.
METHOD. We enrolled 140 unilateral amputees in this cross-sectional study in Port-au-Prince, Haiti. Trained staff administered the assessments by reading the questions aloud to participants. Participants completed the Trinity Amputation and Prosthesis Experience Scales and Locomotor Capabilities Index about 2 yr after the earthquake.
RESULTS. We found no gender differences in psychosocial adjustment and physical outcomes, except for strenuous physical activities and phantom pain, and both genders reported difficulty in social adjustment. After controlling for strenuous physical activities and phantom pain, we found that men showed worse psychosocial adjustment than women.
CONCLUSION. Services for psychosocial adjustment are critical for traumatic amputees and should be incorporated into rehabilitation programs after a disaster. Interventions should consider gender roles in the indigenous culture.
A major event of Antarctic ozone hole influence in southern Brazil in October 2016: an analysis of tropospheric and stratospheric dynamics

Published: March 2018

Abstract. The Antarctic ozone hole is a cyclical phenomenon that occurs
during the austral spring where there is a large decrease in ozone content in
the Antarctic region. Ozone-poor air mass can be released and leave through
the Antarctic ozone hole, thus reaching midlatitude regions. This phenomenon
is known as the secondary effect of the Antarctic ozone hole. The objective
of this study is to show how tropospheric and stratospheric dynamics behaved
during the occurrence of this event. The ozone-poor air mass began to operate
in the region on 20 October 2016. A reduction of ozone content of
approximately 23 % was observed in relation to the climatology average
recorded between 1992 and 2016. The same air mass persisted over the region
and a drop of 19.8 % ozone content was observed on 21 October. Evidence
of the 2016 event occurred through daily mean measurements of the total ozone
column made with a surface instrument (Brewer MkIII no. 167
Spectrophotometer) located at the Southern Space Observatory
(29.42∘ S, 53.87∘ W) in São Martinho da Serra, Rio Grande do Sul.
Tropospheric dynamic analysis showed a post-frontal high pressure system on
20 and 21 October 2016, with pressure levels at sea level and thickness between 1000
and 500 hPa. Horizontal wind cuts at 250 hPa and omega values at 500 hPa revealed
the presence of subtropical jet streams. When these streams were allied with
positive omega values at 500 hPa and a high pressure system in southern Brazil and Uruguay, the advance of the ozone-poor air mass that caused
intense reductions in total ozone content could be explained. Keywords. Atmospheric composition and structure (middle atmosphere – composition and chemistry)
HANZE: a pan-European database of exposure to natural hazards and damaging historical floods since 1870
Authors: Paprotny Dominik , Morales-Nápoles Oswaldo , Jonkman Sebastiaan N. 
Published: March 2018

Abstract. The influence of social and economic change on the consequences of natural hazards has been a matter of much interest recently. However, there is a lack of comprehensive, high-resolution data on historical changes in land use, population, or assets available to study this topic. Here, we present the Historical Analysis of Natural Hazards in Europe (HANZE) database, which contains two parts: (1) HANZE-Exposure with maps for 37 countries and territories from 1870 to 2020 in 100 m resolution and (2) HANZE-Events, a compilation of past disasters with information on dates, locations, and losses, currently limited to floods only. The database was constructed using high-resolution maps of present land use and population, a large compilation of historical statistics, and relatively simple disaggregation techniques and rule-based land use reallocation schemes. Data encompassed in HANZE allow one to "normalize" information on losses due to natural hazards by taking into account inflation as well as changes in population, production, and wealth. This database of past events currently contains 1564 records (1870–2016) of flash, river, coastal, and compound floods. The HANZE database is freely available at https://data.4tu.nl/repository/collection:HANZE.

Published: March 2018

Abstract. This paper describes the new global long-term International Satellite Cloud
Climatology Project (ISCCP) H-series climate data record (CDR). The H-series
data contain a suite of level 2 and 3 products for monitoring the
distribution and variation of cloud and surface properties to better
understand the effects of clouds on climate, the radiation budget, and the
global hydrologic cycle. This product is currently available for public use
and is derived from both geostationary and polar-orbiting satellite imaging
radiometers with common visible and infrared (IR) channels. The H-series data
currently span July 1983 to December 2009 with plans for continued
production to extend the record to the present with regular updates. The
H-series data are the longest combined geostationary and polar orbiter
satellite-based CDR of cloud properties. Access to the data is provided in
network common data form (netCDF) and archived by NOAA's National Centers for
Environmental Information (NCEI) under the satellite Climate Data Record
Program (https://doi.org/10.7289/V5QZ281S). The basic
characteristics, history, and evolution of the dataset are presented herein
with particular emphasis on and discussion of product changes between the
H-series and the widely used predecessor D-series product which also spans
from July 1983 through December 2009. Key refinements included in the ISCCP
H-series CDR are based on improved quality control measures, modified
ancillary inputs, higher spatial resolution input and output products,
calibration refinements, and updated documentation and metadata to bring the
H-series product into compliance with existing standards for climate data
records.
