The evaluation of occlusal relationship between the primary canines and primary molars in 3 to 5-year-old Iranian children

Aim: As to the assessment of occlusal status pertaining to primary canines and molars, the latter is less within reach as it is difficult to guide jaws towards a centric occlusion while maintaining a vintage point in both direct and indirect observation.  This study was originally intended to assess primary canine occlusion as a practical indicator in the evaluation of primary molar occlusion, which is otherwise less feasible in dental examination. Method and materials: A total of 281 healthy children (145 males and 136 females), with complete primary dentition and without erupted permanent teeth and serious caries were examined by a trained student of dentistry. Occlusal patterns of primary second molars were noted as flush terminal plane, distal step and mesial step and for primary canine as class I, class II and class III with regard to Angle’s classification. Results: Overall, Class II canine occlusion seemed to have coincided with more than half of the flush terminal molar occlusions (62%), whereas class I was largely associated with mesial step molars (61.2%). This was also found to be applied to cases undergoing unilateral assessment. (

Study on the interaction between morin-bi(III) complex and DNA with the use of methylene blue dye as a fluorophor probe

Based on our investigation, although both morin-Bi(III) complex and morin can bind to DNA, the nature of the binding was found to be different for each of them. In the presence and absence of the DNA, the morin-Bi(III) complex shows different spectral characteristics which agree with those observed for other intercalators. In this work, the interaction of morin-Bi(III) complex with calf thymus DNA was investigated with the use of methylene blue (MB) dye as a spectral probe and application of UV-Vis spectrophotometry, fluorescence spectroscopy and cyclic voltammetry. The 2:1 morin-Bi(III) complex ratio was calculated by UV-Vis spectroscopy (mole ratio method). The fluorescence signal of Bi(III)-morin complex is increased with DNA addition whereas the fluorescence signal of Morin is decreased with DNA addition. The fluorescence signal of the DNA-complex is quenched by addition of MB which confirms the displacement of the complex with MB. Cyclic voltammetry studies confirm the intercalation reaction. The results showed that only morin-Bi(III) complex can intercalate into the double helix of the DNA. The apparent binding constant of morin-Bi(III) complex with DNA is found to be 2.8 × 10(4) L mol-1, while morin binds in a non-intercalation mode

The theme of the world diabetes day 2014; healthy living and diabetes; a nephrology viewpoint.

Annually, on November 14, the world diabetes day (WDD) is celebrated. WDD is a campaign led by the International Diabetes Federation (IDF) and its member associations throughout the world. It was created in 1991 by IDF and World Health Organization (WHO) in response to increasing concerns about the intensifying threat of diabetes worldwide. The WDD 2014 organization marks the first of a three-year (2014-16) emphasis on "healthy living and diabetes". Replacement of whole grain and cereal-based foods with refined grains in diet planning could be an operative and practical strategy in type II diabetic patients. This strategy beyond the development of glycemic control, leads to more benefits for management of other features of diabetes, diminution of diabetes-induced metabolic disorders, and prevents long-term complications especially diabetic kidney disease and cardiovascular disease

Target trial emulation using hospital-based observational data: demonstration and application in COVID-19

Methodological biases are common in observational studies evaluating treatment effectiveness. The objective of this study is to emulate a target trial in a competing risks setting using hospital-based observational data. We extend established methodology accounting for immortal time bias and time-fixed confounding biases to a setting where no survival information beyond hospital discharge is available: a condition common to coronavirus disease 2019 (COVID-19) research data. This exemplary study includes a cohort of 618 hospitalized patients with COVID-19. We describe methodological opportunities and challenges that cannot be overcome applying traditional statistical methods. We demonstrate the practical implementation of this trial emulation approach via clone–censor–weight techniques. We undertake a competing risk analysis, reporting the cause-specific cumulative hazards and cumulative incidence probabilities. Our analysis demonstrates that a target trial emulation framework can be extended to account for competing risks in COVID-19 hospital studies. In our analysis, we avoid immortal time bias, time-fixed confounding bias, and competing risks bias simultaneously. Choosing the length of the grace period is justified from a clinical perspective and has an important advantage in ensuring reliable results. This extended trial emulation with the competing risk analysis enables an unbiased estimation of treatment effects, along with the ability to interpret the effectiveness of treatment on all clinically important outcomes.This research was funded by the German Research Foundation (original: Deutsche Forschungsgemeinschaft), grant number WO 1746/5-1.Peer ReviewedPostprint (published version
