statement of problem: placement of mini-dental implants when single-tooth restorations are needed and the space is not sufficient to insert a standard diameter implant is indicated. there are many different mini-implant brands with various materials and surface characteristics; however, there are just few studies comparing them with each other. objectives: in this study, finite element analysis...

background: reusing orthodontic mini-screws would reduce treatment cost and lead to more use of mini-screws and improvement of orthodontic treatments. this study has assessed the effects of reprocessing and reusing the titanium mini-screws on their maximum insertion, removal and fracture torque (ft). materials and methods: in this experimental study, 20 titanium mini-screws (1.6-mm × 8-mm) were...

background detection of fetal dna in maternal blood has been examined by many research groups for a few years; thereby, scientists have a shorter way to take to approach prenatal diagnosis of abnormal pregnancies. the y chromosome sequences have recently become the most common applicable indices for fetal sex determination. objectives we conducted an algorithmic x and y mini-short tandem repeat...

BACKGROUND We have previously developed a test for the diagnosis and prognostic assessment of the severe acute respiratory syndrome (SARS) based on the detection of the SARS-coronavirus RNA in serum by real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR). In this study, we evaluated the feasibility of automating the serum RNA extraction procedure in order to increase ...

results the optimal conditions were considered to perform elisa. comparison between results obtained from optimized elisa kit and commercial elisa kit showed a good agreement. background haemophilus influenzae type b (hib) infection has high morbidity and mortality rate, especially in children under 5 years of age. enzyme-linked immunosorbent assay (elisa) technique is the most used method to d...

background: based on genotyping study of human isolates of giardia lamblia ; humans are mainly infected by two assemblages a and b. the present study was carried out to determine the sub-assemblages of g. lamblia isolated from food handlers referred to kashan health centers, central iran, 2015. methods: in this cross-sectional study, 3653 stool samples collected from food-handlers that annually...

Abstract. Chrisnawati L, Ernawiati E, Yulianty, Hariri MR. 2022. Polymorphism analysis of drought tolerance gene OsDREB2A in Indonesian local rice from Lampung, Indonesia. Biodiversitas 23: 6352-6357. Drought stress is a significant threat to cultivation and the selection drought-tolerant plants needed find superior plants. The plays role regulation widely used as marker. Therefore, this study ...

Abstract Bitti ( Vitex cofassus ) is a native species in Indonesia and superior wood South Sulawesi. This type hardwood that sought after exported large enough quantities. A narrow genetic base requires joint efforts to develop plant varieties, so it necessary carry out selection activities obtain diversity of traits. The most advanced method assessing molecularly based approach using the Inter...
