The aim of this study was to assess the effect of a chlorhexidine digluconate solution (CHX) applied as an antiproteolytic agent for controlling erosive tooth wear or as part of the adhesive treatment on long-term bond strength to eroded dentin. Dentin specimens were abraded with a 600-grit silicon carbide (SiC) paper for 1 min (sound dentin - S), subsequently treated with 2% CHX for 1 min (with excess removed, followed by a 6-hour rest), and eroded by exposure to Coca-Cola for 5 min, three times a day, for 5 days (CHX-treated and eroded dentin - CHXE), or only eroded (eroded dentin - E). The specimens were acid-etched (15 s), rinsed (30 s), dried (15 s), and rehydrated with 1.

To study the enhancement effect of carbon nanotubes (CNTs) on the splitting tensile properties of foamed concrete backfill in which cement and fly ash were used as the cementitious materials and natural sand was used as the aggregate, specimens of CNT-modified foamed concrete backfill were prepared. Brazilian splitting tests were used to investigate the splitting tensile strength of the CNT-modified foamed concrete backfill, and the digital speckle correlation method was used to analyze the stress field characteristics and crack expansion law of the specimens during splitting tensile testing. The stress-strain characteristics and energy dissipation laws of the backfill were studied at various static loading rates, and a relationship between the splitting tensile strength, ultimate strain, and loading rate was established.

Article Synopsis
- Prior familiarity with faces, especially when they are known US celebrities, enhances recognition and source memory compared to unfamiliar European celebrities.
- In two experiments, both familiar and unfamiliar faces showed improved recognition rates with repetition during learning, but participants were more accurate with familiar faces.
- Experiment 2 revealed that while familiar faces were recognized more frequently, they were also more prone to being incorrectly identified as previously seen when paired with new backgrounds, suggesting complexities in face memory recall.
Objective: This study investigates the effect of partial common extensor tendon(CET) tears on demographic, clinical and ultrasound(US) parameters in patients with lateral epicondylitis(LE). The research aimed to provide a comprehensive understanding of how these US-detected partial tears, influence the clinical presentation and imaging findings associated with LE.

Mechanistic studies on the effect of endogenous proteins on the starch retrogradation characteristics of corn before and after postharvest ripening.

The corn starch-protein complexes before postharvest ripening (JD-0) and after postharvest ripening (JD-40) were subjected to protease treatment, and the influence of protein on starch retrogradation was studied. Kinetic studies of starch retrogradation showed that protein reduced the retrogradation rate constant (k) of starch by 25.46 % (JD-0) and 7.
