The aim of the research was to evaluate the efficacy of Invisalign Lite package in mild and moderate anterior crowding treatment from the perspective of orthodontists and lay people. Ten subjects treated with Invisalign Lite were consecutively selected and divided into 2 groups: less than 2mm crowding (mild) and more than from 2mm to 5mm crowding (moderate). Images pre- and post-treatment of each subject were obtained from digital cast and randomly arranged in a Power Point presentation. The evaluation was performed by 109 individuals divided into 2 groups: orthodontists and lay people. They were asked to assign a score for teeth alignment from 1 (poor) to 5 (excellent). Also, the evaluators had to answer for each of the images, if in their opinion orthodontic treatment was necessary. In all groups the Kolmogorov-Smirnov normality test was performed. Paired t-test and non-parametric Wilcoxon test were used for paired comparison. The independent t-test and non-parametric Mann-Whintney were used for comparing evaluators groups and the amount of crowding. In all tests a 5% (p<0,05) significance level was adopted. For the orthodontists, alignment evaluation increased from 2,85 to 4,13 after orthodontic treatment. The scores assigned by lay people increased from 2,54 to 3,69. Orthodontists pointed out that they would indicate orthodontic treatment for 11,15% of the post-treatment images. For lay people, orthodontic treatment would be necessary for 35,63% of post-treatment images.

Published: January 2022

The mesial inclination of permanent molars is commonly noticed and may be caused by several factors, including premature loss of the primary first deciduous molars, loss of the first permanent molars, periodontal disease. The device selection for correcting this condition depends on the degree of inclination and the desired movement. The mechanical efficiency and the easy manufacturing and installation make the root spring an excellent alternative for molar uprigthing. The objective of this study was to report the clinical case of a simultaneous verticalization of four molars with root spring anchored with miniplates. A 35 years-old male patient presented as main complaint dissatisfaction regarding chewing. Clinical and radiographic analysis showed the early loss of the first lower molars, which led to the inclination of teeth 37, 38, 47 and 48 with total closure of the space corresponding to teeth 36 and 46. The biomechanical planning consisted of the simultaneous uprigthing of the four molars with root spring activated in GVI and anchored in two miniplates installed in the anterior region of the mandible. In this clinical case report, the root spring activated in geometry VI showed to be a good mechanical alternative, as it is a simple, precise, and comfortable for the patient in cases in which molars uprigthing is necessary without vertical forces acting on the system.

Uma história da primeira página: 50 anos de primeiras páginas de jornais brasileiros entre 1875 e 1925
Authors: Barsotti Adriana
Published: January 2022

Este artigo mapeia as origens da primeira página moderna nos jornais brasileiros, com base na análise de 407 capas de cinco periódicos influentes no período compreendido entre 1875 e 1925: O Paiz, Gazeta de Notícias, Correio da Manhã, Jornal do Brasil e O Estado de S. Paulo. A pesquisa revelou que as primeiras manchetes surgiram entre 1905 e 1906 em quatro dos títulos e que, em 1915, as capas com manchetes, títulos, fotos e ilustrações já eram uma realidade na Gazeta de Notícias e no Correio da Manhã. Em 1925, O Paiz também  seguia o padrão. O Estado de S.Paulo e o Jornal do Brasil fogem à regra na segunda década do século passado, validando o pressuposto teórico do estudo, segundo o qual a história se faz em meio a múltiplas temporalidades, rupturas e descontinuidades e que, portanto, não haveria uma data fundadora em comum para a incorporação da primeira página moderna na história do jornalismo brasileiro.

Determine Most Stable Isobar for Nuclides with A= (15-30) & (101- 115)
Authors: S. Nayyef Murtadha , T. Jaralla Naz
Published: January 2022

In this study the most stable isobar for some isobaric families (light and  intermediate ) nuclei with mass number (A) equals to (15-30) & (101- 115) have been determined. This determination of stable nuclide can help to determine the suitable nuclide, which can be used in different fields.

Most stable isobar can be determined by two means. First: plot mass parabolas (plotting the binding energy (B.E) as a function of the atomic number (Z)) for these isobaric families, in this method most stable isobars represent the lowest point in mass parabola (the nuclide with the highest value of binding energy).

Second: calculated the atomic number for most stable isobar (ZA) value.

Our results show that there is only one stable nuclide for isobars with odd mass number (A) (one mass parabolas), while for nuclides with an even mass number (A) there is more than one stable nuclide (two mass parabola).

Also, our results show that nuclides representing the most stable isobars in the two methods, which used in this study practically, are the same nuclide.

Datura stramonium is a bushy annual plant belonging to the family Solanaceae. This study investigated the antimicrobial effects of methanolic and aqueous extracts of seeds and leave of Datura stramonium plant. The test organisms Salmonella Typhi and Shigella species were obtained from stock cultures at the National Veterinary Research Institute in Vom, Plateau State, Nigeria. The identification of the test organisms and the plant extracts were done using standard microbiological procedures. The results obtained showed that antibacterial activities of Methanolic leaf extracts of Datura stramonium produced inhibitions zone of 25mm on concentration of 50mg/ml and 25mm on concentration of 100mg/ml against Salmonella typhi while inhibition zone of 20mm, were observed on concentrations 25mg/ml, 50mg.ml and 100mg/ml against Shigella species. The aqueous leaves extracts produced no zone of inhibition against Salmonella typhi while zone of inhibitions of 10mm was observed on concentration 50mg/ml and 100mg/ml against Shigella species. The methanolic seeds extract produced zone of inhibition of 20mm on both concentrations of 50mg/ml and 100mg/ml against Salmonella typhi while inhibition zones of 25mm was observed on concentrations 50mg/ml and 100mg/ml against Shigella specie. The aqueous seeds extracts produced no zone of inhibition against both test organisms (Salmonella typhi and Shiegella species). The Minimum Inhibitory Concentration (MIC) of Datura stramonium methanolic leaves extract of Salmonella typhi was 12.5mg/ml while Shigella Species had MIC of 25mg/ml. There was no MIC of aqueous leaves extract against Salmonella typhi while that of shigella species was 100mg/ml. The MIC of methanolic Seeds extract shows 25mg/ml on both test organisms and no MIC of aqueous seed extract on both test organisms. This research has enormously revealed that extracts of Datura stramonium leaf possess more antimicrobial potency against Salmonella typhi and Shiegella species than the seed extracts. Also, the results also revealed that methanolic extract has more potency than the aqueous extract on either the leaves or seeds of Datura stramonium. Conclusively, Datura stramonium extracts demonstrated bactericidal potential against both Salmonella typhi and Shiegella species which indicate that the plant can be a good resource for herbal drugs that can be used against Gram negative bacteria.
