The effect of fiber-reinforced composite versus band and loop space maintainers on oral Lactobacillus acidophilus and Streptococcus mutans levels in saliva

Journal of Indian Society of Pedodontics and Preventive Dentistry, 2018
Background: Orthodontic bands have been shown to alter oral microbial flora that lead to convert caries-free patients to moderate or high caries risk individuals.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Assessing the Awareness of Parents and Satisfaction of Children with Intraoral Space Maintainers

Journal of Islamic Dental Association of Iran, 2019
Background and Aim: Space maintenance is an important process in the mixed dentition as a preventive measure for multiple malocclusion problems related to the loss of arch length. The awareness of parents and the satisfaction of children are two critical

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

How to maintain the genome in nuclear space

Current Opinion in Cell Biology, 2020
Genomic instability can be life-threatening. The fine balance between error-free and mutagenic DNA repair pathways is essential for maintaining genome integrity. Recent advances in DNA double-strand break induction and detection techniques have allowed the investigation of DNA damage and repair in the context of the highly complex nuclear structure ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

SPACE CONTROL IN MIXED DENTITION - SPACE MAINTAINERS

Jurnalul Pediatrului, 2020
Maintaining the child's oral cavity in optimal health by preserving the morpho-functional integrity of primary teeth, given the influence they have on the growth and development of the stomatognathic system is the duty and responsibility of the pedodontist. In addition to prevention, increased attention should be granted to the space control in case of
