Abstract Cardinality and rank functions are ideal ways of regularizing under-determined linear systems, but optimization the resulting formulations is made difficult since both these penalties non-convex discontinuous. The most common remedy to instead use $$\ell ^1$$ ℓ 1 </mml:mat...
Objective: Extraction of premolars is believed to affect the eruption of third molars. This comparative study aimed to assess the change in angulation of third molars following first/second premolar extraction versus non-extraction orthodontic treatments. Methods: This historical cohort study was conducted on patients assigned to three treatment groups: extraction of mandibular first premolars ...
The involvement of tRNA structural elements beyond the anticodon in aminoacyl-tRNA (aa-tRNA) selection by the ribosome has revealed that substrate recognition is considerably more complex than originally envisioned in the adaptor hypothesis. By combining recent breakthroughs in aa-tRNA synthesis and mechanistic and structural studies of protein synthesis, we have investigated whether aa-tRNA re...
BACKGROUND Small non-coding RNAs (microRNAs) have been evolved to master numerous cellular processes. Genetic variants within microRNA seed region might influence microRNA biogenesis and function. The study aimed at determining the role of microRNA-499 (MIR-499) gene family polymorphism as a marker for susceptibility and progression of bronchial asthma and to analyze the structural and function...
