New method of measuring subjective well-being: prospective validation study of the 'Daily Experience Sampling Questionnaire' (DESQ) in patients with psoriasis and healthy subjects in Germany.

Objectives: To validate the newly developed Daily Experience Sampling Questionnaire (DESQ) that measures affective subjective well-being (SWB). The DESQ is an end-of-day diary in which respondents retrospectively rate their SWB at six different, randomly determined moments; it is completed over 1 week. The DESQ shall provide an alternative or complementary approach to existing methods of near-time SWB measurement (experience sampling, Day Reconstruction Method).

Air polishing with erythritol powder - In vitro effects on dentin loss.

Context: Low-abrasive polishing powders such as glycine (GLY) or erythritol (ERY) are used for subgingival air polishing. GLY was reported to possibly affect the dentin surface, while this is unclear for ERY.

Aims: This study aimed to evaluate the substance loss from the dentin surface by air polishing with ERY at different settings for pressure (PR), distance (DI), and angulation of the spray jet to the surface (AJ).

Cleaning effectiveness of implant prophylaxis instruments.

Purpose: The aim of this study was to evaluate the cleaning effectiveness of implant prophylaxis instruments on polished and acid-etched implant surfaces.

Materials And Methods: Biofilm layers of Streptococcus mutans were grown on a total of 80 titanium disks; 40 disks were polished and 40 were acid-etched. Five disks of each surface were cleaned using each of seven implant prophylaxis instruments: (1) manual plastic curette, (2) manual carbon fiber-reinforced plastic (CFRP) curette, (3) sonic-driven prophylaxis brush, (4) rotating rubber cup with prophylaxis paste, (5) sonic-driven polyether ether ketone (PEEK) plastic tip, (6) ultrasonic-driven PEEK plastic tip, and (7) air polishing with amino acid (glycine) powder.

Effects of rotenone on inducible nitric oxide synthase and cyclooxygenase-2 mRNA levels detected by real-time PCR in a rat bladder ischemia/reperfusion model.

We aimed to determine whether rotenone treatment prevents induced ischemia/reperfusion (I/R) damage in rat bladders by detecting inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) levels by real-time PCR (RT-PCR). A total of 18 Sprague-Dawley albino rats were used in this experiment. The experimental groups each consisted of 6 rats and were treated as follows: group I, control; group II, I/R; group III, rotenone + I/R.

Preparation time and surface roughness of core foundation resins and dentin.

Statement Of Problem: It is unclear if the preparation of core foundation resins is similar to that of dentin.

Purpose: The purpose of this in vitro study was to compare the preparation time and resulting roughness of 5 core foundation resins and dentin.

Material And Methods: Standardized preparations (10 mm length, 5 mm height) were made of 5 specimens of 5 core materials with a device-mounted dental handpiece (150 000 rpm, water-cooling) with weight-controlled contact pressure (50 g).
