Interfacial adaptation of newly prepared nano-tricalcium silicate-58s bioactive glass-based endodontic sealer.

Background: The sealer's interfacial adaptability is one of the critical factors for successful root canal therapy. This study evaluated and compared the interfacial adaptability of newly prepared nano-tricalcium silicate-58s bioactive glass-based endodontic sealer (C S-BG-P) to root dentin with two bioactive sealers Nishika Canal Sealer BG and BioRoot RCS.

Methods: Thirty newly extracted single-rooted lower premolars were decoronated and instrumented.

New strategies for Helicobacter pylori isolation and sequencing analysis for virulence genes contributing to its pathogenicity.

Background: Helicobacter pylori is a fastidious pathogen that is required a complicated medium for growth. Invading epithelial cells of the stomach. H.

Remineralization ability of different root canal sealers.

Aims: This research was designed to contrast the biocompatibility and remineralization ability of different sealers (BioRoot, MTA-FillApex and GuttaFlow-Bioseal).

Method: Twenty rabbits were used in this study, they were randomly divided into 4 groups equally depending on the observation time"3,7,14, and 28 days" post-implantation. Each rabbit was generally anesthetized,"7cm"long incision was made on the skin of the right and left sides of the ventral aspect of the mandible of each rabbit, 4 bony cavities of approximately"5mm"in depth and"2mm"in diameter (2 cavities on the left side and 2 cavities on the right side of mandible of each rabbit) were made in the cortical surface of the buccal alveolar bone.

The secrets of environmental Pseudomonas aeruginosa in slaughterhouses: Antibiogram profile, virulence, and antibiotic resistance genes.

Environmental pollution is a serious problem that can cause sicknesses, fatality, and biological contaminants such as bacteria, which can trigger allergic reactions and infectious illnesses. There is also evidence that environmental pollutants can have an impact on the gut microbiome and contribute to the development of various mental health and metabolic disorders. This study aimed to study the antibiotic resistance and virulence potential of environmental Pseudomonas aeruginosa (P.

Physical-chemical properties and acellular bioactivity of newly prepared nano-tricalcium silicate-58s bioactive glass-based endodontic sealer.

Objectives: To evaluate the physiochemical properties and apatite-forming ability of a newly prepared nano-tricalcium silicate-58s bioactive glass-based endodontic sealer (CS-BG-P) and compare its results with the Nishika BG canal sealer and BioRoot™ RCS.

Methods: The physicochemical properties (setting time, flow, solubility, film thickness, and radiopacity) of CS-BG-P, Nishika BG canal sealer, and BioRoot™ RCS were evaluated in accordance with ANSI/ADA 57/2000 (reaffirmed 2012) and ISO 6876:2012 for root canal sealing materials. The in vitro apatite-forming ability was evaluated after 28 days of immersion of disc-shaped specimens in phosphate-buffered saline (PBS) using field emission scanning electron microscopy and energy-dispersive X-ray spectroscopy.

Purification and characterization of catechol 1,2-dioxygenase (EC 1.13.11.1; catechol-oxygen 1,2-oxidoreductase; C12O) using the local isolate of phenol-degrading Pseudomonas putida.

The purpose of the present study was to purify and characterize the catechol 1,2-dioxygenase (EC 1.13.11.

Effect of Oral Vitamin D3 on Dental Caries: An In-Vivo and In-Vitro Study.

Aim Vitamin D3 plays an important role in affecting the overall remineralization process of the dentition. The use of supplements help to keep the levels at optimum and thus reduce the chances of treating very early lesion of caries. Hence the aim was to investigate the indirect effects of oral vitamin D3 on microhardness and elemental weight percentage of Calcium (Ca) and Phosphorous (P) in enamel surface with an artificially initiated carious lesion.

A Novel Genetic Determination of a Lectin Gene in Iraqi Isolates and Use of Purified Lectin as an Antibiofilm Agent.

Background: Lectin was initially called hemagglutinin or agglutinin because of its capacity to agglutinate human as well as human erythrocytes. They are a heterogeneous group of proteins or glycoproteins of nonimmune origin. Because of their chemical properties, they have become a useful tool in several fields such as immunology, cell biology, molecular biology, membrane structure, pharmacology, cancer research, clinical chemistry, and genetic engineering.

Identification of a novel function for the FtsL cell division protein from Escherichia coli K12.

Analysis of the essential cell division protein FtsL demonstrates the partial conservation of a cysteine-pair within the trans-membrane region which itself is flanked by histidine-pairs in the cytosol and periplasm. Similar arrangements of such amino acids are seen in proteins known to transport/bind metal ions in biological systems. Heterologous expression of ftsL in Escherichia coli K12 confers a Zn(II)-sensitive phenotype and alteration of the candidate metal-ion binding residues cysteine or histidine substantially alters this phenotype.
