Nano Sized ZnO/MnO2/Gd2O3 Ternary Heterostructures for Enhanced Photocatalysis
Authors: Pranesh Shubha , Nagaraju Jayalakshmi 
Published: December 2019

Background:
The cost of effluent treatment is not affordable by small scale
industries especially in developing countries. Hence the effluent is discharged without
treatment into water bodies. The dyes do not degrade easily and possess a major
concern to be addressed. The aquatic life is highly affected and also leads to bio
magnification of the chemicals through the food chain.

Objective:
To synthesize a ternary hybrid structure for enhanced photocatalytic activity
under visible light. It is intended to reduce toxicity caused by dyeing units.

Methods:
Synthesized nanomaterials are characterized and used as photocatlyst for the
degradation of methylene blue. In degradation experiment known weight of catalyst was
added to known volume of an aqueous solution of dye at various concentrations. The
solutions are aerated in dark for about 30 min. At the time of irradiation of light, known
aliquot of the aqueous mixture was collected at an interval of constant time each from the
reaction solution. The catalyst in the mixture was separated by centrifuging the mixture
and absorbance was measured. The % of degradation of the dye can be determined
knowing initial and final dye concentration.

Result:
Heterostructures are characterized with analytical tools such as X-ray diffraction,
Fourier transform infrared spectroscopy. Band gap of photocatlyst is calculated
by application of UV-Vis spectroscopy. Morphology is seen using scanning electron
microscopy and transmission electron microscopy. Distribution of constituent structures
is observed with energy-dispersive X-ray (EDX) spectroscopy. The structures are used
for photocatalytic degradation of methylene blue dye solution under UV and visible
light irradiation. Heterostructures showed best performance under visible light.

Conclusion:
The ternary hybrid nanostructure ZnO-MnO2-Gd2O3 was effectively prepared
by a simple solution combustion method. The ternary compound shows wide
range of absorption by expanding absorption band both in UV and visible regions.
Structures showed better catalytic property under visible light.

Authors: Mathias Emmily Flügel , Santos Gilberto Lacerda 
Published: December 2019

O uso de comunidades virtuais como instrumentos de educação corporativa ainda não se constitui em uma prática comum nas organizações. Apesar do grande número de comunidades disponíveis e das possibilidades de comunicação, interação, troca de conhecimentos e informações que as comunidades virtuais possibilitam, são poucas as situações em que se verifica a sua utilização em situações de educação em meios organizacionais. O presente artigo, decorrente da Tese de Doutorado de Mathias (2010), trata da importância das comunidades virtuais na educação corporativa diante de uma realidade determinada pela sociedade informacional. Assim, parte dos resultados de pesquisa sobre as relações entre educação corporativa, gestão do conhecimento e novas tecnologias da informação, comunicação e expressão, realizada no Tribunal de Contas da União em 2010. A percepção dos participantes da pesquisa e as teorias que discutem questões relacionadas à interatividade e aos processos comunicacionais demonstram que o uso das comunidades virtuais pode representar um importante avanço para a educação corporativa nas organizações.Palavras-chave: educação corporativa, educação a distância, tecnologia da informação, gestão do conhecimento, sociedade da informação

Medical Videography Using a Mobile App: Retrospective Analysis
Authors: Cambron Julia C , Wyatt Kirk D , Lohse Christine M , Underwood Page Y , Hellmich Thomas R 
Published: December 2019

Background
As mobile devices and apps grow in popularity, they are increasingly being used by health care providers to aid clinical care. At our institution, we developed and implemented a point-of-care clinical photography app that also permitted the capture of video recordings; however, the clinical findings it was used to capture and the outcomes that resulted following video recording were unclear.

Objective
The study aimed to assess the use of a mobile clinical video recording app at our institution and its impact on clinical care.

Methods
A single reviewer retrospectively reviewed video recordings captured between April 2016 and July 2017, associated metadata, and patient records.

Results
We identified 362 video recordings that were eligible for inclusion. Most video recordings (54.1%; 190/351) were captured by attending physicians. Specialties recording a high number of video recordings included orthopedic surgery (33.7%; 122/362), neurology (21.3%; 77/362), and ophthalmology (15.2%; 55/362). Consent was clearly documented in the medical record in less than one-third (31.8%; 115/362) of the records. People other than the patient were incidentally captured in 29.6% (107/362) of video recordings. Although video recordings were infrequently referenced in notes corresponding to the clinical encounter (12.2%; 44/362), 7.7% (22/286) of patients were video recorded in subsequent clinical encounters, with 82% (18/22) of these corresponding to the same finding seen in the index video. Store-and-forward telemedicine was documented in clinical notes in only 2 cases (0.5%; 2/362). Videos appeared to be of acceptable quality for clinical purposes.

Conclusions
Video recordings were captured in a variety of clinical settings. Documentation of consent was inconsistent, and other individuals were incidentally included in videos. Although clinical impact was not always clearly evident through retrospective review because of limited documentation, potential uses include documentation for future reference and store-and-forward telemedicine. Repeat video recordings of the same finding provide evidence of use to track the findings over time. Clinical video recordings have the potential to support clinical care; however, documentation of consent requires standardization.

Published: December 2019

Exclusive breastfeeding during the first six months of life is extremely important for the development of the dentocraniofacial structure, occlusion, breathing and swallowing during childhood. The prevalence severity rate of malocclusion in children who were breastfed is lower than those who were bottle-fed. The aim of this study is to evaluate the associations of infant feeding patterns on the deciduous second molar relationship in preschool aged children (3-5 years old children) of selected preschools in and around Medan Selayang. This study used analytic cross-sectional study design as the research method. The sampling was carried out by purposive sampling technique. This study involved 130 children aged 3-5 years as the sample, who consisted of two groups, the exclusively breastfed group and the bottle-fed group with the inclusion criteria of the children having a good oral and dental health. The result is statistically analyzed using Chi Square with a significance level of p<0.05. There was a significant difference between children who were breastfed and those who were bottle-fed. Children who were breastfed mostly had mesial step (55, 4%), followed by distal step(27.7%) and flush (16.9%), while those children who were bottle-fed mostly had distal step (46.2%), flush (33.8%), and mesial steps (20%). Based on Chi Square test, it is shown that there is a significant relationship between infant feeding patterns to primary molar relationships (p<0.001).

Published: December 2019

La relevancia histórica de Guanabacoa, poblado que surge como reducción de indios en La Habana y donde se sucedieron importantes procesos sociohistóricos, contrasta con la exigüidad de intervenciones arqueológicas practicadas, y la necesidad de dilucidar cuestiones relativas al emplazamiento de la primera iglesia y cementerio, área que constituyó el núcleo urbano a partir del cual se expandió y conformó el actual municipio. En función de esto se implementó el proyecto arqueológico Indios naturales y floridanos en Guanabacoa con el propósito de constatar la ubicación de las mencionadas estructuras, enfocado además en la presencia e interacción de indios naturales y floridanos. El análisis de las abundantes y significativas evidencias arqueológicas halladas constata la continuidad de algunas producciones tradicionales aruacas y la presencia de indios floridanos en el entorno urbano guanabacoense del siglo xviii. Igualmente, ilustran sobre el comercio, la producción de azúcar, la religión, el divertimento, la construcción de inmuebles, la alimentación, el procesamiento de alimentos y actividades que incluían elementos vinculados con la apariencia personal. Los resultados obtenidos en la primera etapa de investigación arqueológica evidencian la necesidad de continuar la implementación del proyecto en el área seleccionada.

Authors: Mamieva Z. A. , Poluektova E. A. , Shifrin O. S. 
Published: December 2019

Aim. To review data on the efficiency and safety of using Ustekinumab in patients with Crohn’s disease.Key findings. Ustekinumab is a fully human monoclonal antibody of the IgG1k class to the p40 subunit of IL-12 and IL-23. The drug interrupts the cascade of humoral and cellular reactions leading to transmural inflammation of the intestinal wall by blocking the interaction of the p40 subunit with the IL-12Rβ1 chain on the surface of T-lymphocytes and NK cells. A number of placebo-controlled studies have demonstrated the effectiveness of Ustekinumab in the induction and the maintenance of remission in those patients with Crohn’s disease who showed no response to conventional therapy (glucocorticosteroids and immunosuppressants) and therapy with TNF-α antagonists. In addition, the efficiency of Ustekinumab in maintaining a clinical response and clinical remission over two years of therapy has been shown. The drug has a favourable safety profile and a low immunogenicity.Conclusion. The reviewed studies show Ustekinumab to be an effective and safe drug for the induction and the maintenance of clinical remission in patients with Crohn’s disease.

Aim. To evaluate the efficacy of transarterial chemoembolization in patients with metastases of colorectal cancer in the liver.Materials and methods. A study aimed at investigating the effect of selective transarterial chemoembolization (TACE) of the hepatic artery on liver metastases in colorectal cancer was conducted at the Oncology Centre of the RZhD Central Clinical Hospital No. 2 named after N.A. Semashko, Moscow. The research basis included data for 10 patients, who had undergone chemoembolization of the hepatic arteries using Biosphere microspheres 50– 100 µm — 25 mg and doxorubicin 50 mg.Results. Both immediate and long-term results of up to 12 months were evaluated using the RECIST 1.1 scale. A partial response was achieved after 4 TACE treatments in 22.2 % of cases. The stabilization of the oncological process in the liver was observed after 9 TACE treatments in 50 % of cases. Disease progression was noted after 5 procedures in 27.8 % of cases.Conclusions. Transarterial chemoembolization of metastatic liver lesions in patients with colorectal cancer can be used according to certain indications in specialized centres providing endovascular treatment services.
Depth-dependence of Degree of Conversion and Microhardness for Dual-cure and Light-cure Composites
Authors: Wang R , Wang Y 
Published: December 2019

Clinical Relevance
New dual-cure bulk-fill composites show promise for uniform degree of conversion and microhardness throughout the entire depth of direct restorations.

SUMMARY

Objective:
The aim of this study was to evaluate the degree of conversion (DC) through micro-Raman spectroscopy and surface microhardness in Vickers hardness (VHN) of three new dual-cure bulk-fill resin-based composites (RBCs) compared with light-cure bulk-fill and incremental RBCs at two clinically relevant depths and for two light irradiation times.

Methods:
Three commercially available restorative dual-cure bulk-fill RBCs (BulkEZ, HyperFIL, and Injectafil) were evaluated and compared with three light-cure RBCs (Filtek Bulk Fill Flowable, Filtek One Bulk Fill, and incremental Filtek Z250) as controls. Specimens were prepared in two different depths (0.5 mm and 5 mm) and were light irradiated for 20 seconds or 40 seconds. Self-cure was also evaluated for the three dual-cure bulk-fill RBCs. Micro-Raman spectroscopic measurements and VHN tests (n=5) were made after 24 hours of dry storage in the dark at room temperature for all test conditions. Data were analyzed using one-way and two-way analyses of variance (α=0.05).

Results:
All tested RBCs showed significantly higher DC and VHN values at 0.5-mm depth than at 5-mm depth, with the exception of BulkEZ, which showed similar DC and VHN values at two depths. The three dual-cure bulk-fill RBCs showed significantly higher DC than the three light-cure RBCs under the same curing condition. The three dual-cure RBCs showed much smaller differences in VHN values between the two depths than the three light-cure RBCs. Twenty seconds and 40 seconds of light irradiation did not generate significant difference in DC and VHN values for the three dual-cure bulk-fill RBCs at either depth or for the three light-cure RBCs at the 0.5-mm depth; however, 40 seconds of light irradiation generated significantly higher DC and VHN values for One Bulk Fill and Z250 at the 5-mm depth compared with 20 seconds of light irradiation.
Influence of Different Cordless Light-emitting-diode Units and Battery Levels on Chemical, Mechanical, and Physical Properties of Composite Resin
Authors: Cardoso IO , Machado AC , Teixeira DNR , Basílio FC , Marletta A , Soares PV 
Published: December 2019

Clinical Relevance
Irradiance may decrease as the light-emitting diode (LED) is discharged. Therefore, the LED must be charged carefully to prevent the possibility of influencing the chemical, mechanical, and physical properties of composite resin.

SUMMARY
The aim of this study was to evaluate the influence of different light-emitting diode (LED) curing units and battery levels on the chemical, mechanical, and physical properties of composite resins. The irradiance for each cycle from full to completely discharged battery level was evaluated, for five different new cordless LED units: Optilight Color (Gnatus), Bluephase (Ivoclar), Valo (Ultradent), Radii Plus (SDI), and Radii Xpert (SDI). After the irradiance evaluation, composite resin specimens were prepared and light cured, while varying the battery level for each LED unit: high level (HL, 100%), medium level (ML, 50%), and low level (LL, 10%). The degree of conversion, diametral tensile strength, sorption, and solubility were also evaluated. Data were checked for homoscedasticity and submitted to two-way and three-way analysis of variance, depending on the test performed, followed by the Tukey test with a significance level of 95%. A negative correlation was found between irradiance and cycles of light curing, which was checked by the Pearson correlation test. Valo and Radii Xpert were not influenced by the battery level in any test performed. However, different battery levels for some LED units can influence the degree of conversion, diametral tensile strength, sorption, and solubility of composite resins.
