Bidirectional electro-enzymatic reaction of coenzyme F using benzyl viologen and F-dependent sulfite reductase.

Coenzyme F is recognized as a crucial electron carrier in methane-generating metabolism but, beyond this, has garnered significant attention for its role in diverse microbial physiologies and relevance in industrial, medical, and environmental applications. However, one limitation of current application of F is the necessity of chemical electron donors for its reduction. In this study, an electrochemical reaction system was designed to facilitate electron transfer between the electrode and F using F-dependent sulfite reductase (Fsr) as the catalyst and benzyl viologen (BV) as the redox mediator.

Site-level progression of periodontal disease during a follow-up period.

Periodontal disease is assessed and its progression is determined via observations on a site-by-site basis. Periodontal data are complex and structured in multiple levels; thus, applying a summary statistical approach (i.e.

Potential impact of surgical periodontal therapy on oral health-related quality of life in patients with periodontitis: a pilot study.

Aim: To gain insight into the impact of periodontal surgery on oral health-related quality of life (QoL) of patients with periodontitis.

Material And Methods: Study participants were recruited from moderate to severe periodontitis patients. After initial periodontal therapy, participants received periodontal surgery.

Antibacterial activity of povidone-iodine against an artificial biofilm of Porphyromonas gingivalis and Fusobacterium nucleatum.

Objective: To investigate the antibacterial activity of povidone-iodine (PVP-I) on an artificial dual species biofilm of periodontal pathogens.

Design: Porphyromonas gingivalis or Fusobacterium nucleatum grown in broth culture was inoculated on polycarbonate membrane (PCM) tissue culture inserts. After incubation for 72 h, PVP-I solutions were applied to the biofilm for the time period ranging from 0.

Effect of initial periodontal therapy on oral health-related quality of life in patients with periodontitis in Japan.

Background: It is becoming increasingly important for periodontists and dental hygienists to take a biopsychosocial approach to care when considering periodontal interventions. However, information on how patients perceive periodontitis and its treatment is limited. The purpose of the present study is to gain insight into the patient perception of oral health and the impact that periodontitis and treatment have on self-assessed quality of life (QoL).

Improvement of hydrogelation abilities and handling of photocurable gelatin-based crosslinking materials.

Three types of eosin-derivatized gelatins (eosin-gelatins) with different molecular weights (M(w)) of ca. 15 kDa (low-molecular-weight eosin-gelatin, LEG), ca. 30 kDa (medium-molecular-weight eosin-gelatin, MEG), and ca.
