BACKGROUND It is not yet clear from the current literature to what extent masticatory muscle activity is affected by the use of flexible acrylic resin in the construction of implant-supported mandibular overdentures. OBJECTIVE To compare masticatory muscle activity between patients who were provided with implant-supported mandibular overdentures constructed from flexible acrylic resin and tho...

Pulse oximetry (Spo2) is a simple, noninvasive method that is widely used to determine oxygen saturation in patients undergoing surgical procedures. Artificial acrylic nails have recently become fashionable to strengthen and lengthen nails. This study investigates the effect of unpolished acrylic nails on the measurement of oxygen saturation by pulse oximetry. Data were collected during a 3-mon...

Objective. This study evaluated the effect of microwave sterilization on the hardness of silicone and acrylic based relining materials. Material and Method. Acrylic resin specimens were fabricated and the resilient materials (GC Extra soft and Trusoft) were bonded to these specimens, which acted as a denture base. The specimens were divided into 6 groups (n=10); i.e. 3 groups of silicone and 3 ...

An experimental investigation is conducted to calculate the shock standoff (SSO) distance in front of an acute-angled wedge. For this experimentation, simple water flows channel analysis is carried out. The flow velocity is varied from 13.2 cm/s to 25.5 cm/s increasing in steps of 1 cm/s. A velocity of 13.2 cm/s corresponds to Froude number 1.13 and velocity of 25.5 cm/s to Froude number 1.41. ...

In this study, we investigated the effect of different solutions--coffee, tea, Turkish coffee, artificial saliva, mouthwash, denture cleanser, and distilled water--on the bond strength of soft lining materials (one acrylic- and three silicone-based) to acrylic resin. Acrylic specimens (40x10x10 mm) were prepared for the bond strength test. The specimens were stored in different solutions and te...

An exothermic reaction, leading to 3-(2-furyl)acrylic anhydride and a little amount of furfurylideneacetone is taking place when reacting 3-(2-furyl)acrylic acid in acetic anhydride above 120°C. The 3-(5-acetyl-2-furyl)acrylic acid was formed under the afore-mentioned conditions only in the presence of H 3 P 0 4 . The 3-(2-furyl)acrylic anhydride is more stable towards HNO, at temperatures unde...

BACKGROUND The dopamine transporter gene (DAT1) and visual memory deficits have been consistently reported to be associated with attention-deficit/hyperactivity disorder (ADHD). This study aimed to examine whether a DAT1 haplotype affected functional and structural brain alterations in children with ADHD and whether those alterations were associated with visual memory. METHOD We recruited a t...

OBJECTIVES To perform dual analysis of tumor perfusion and glucose metabolism using perfusion CT and FDG-PET/CT for the purpose of monitoring the early response to bevacizumab therapy in rabbit VX2 tumor models and to assess added value of FDG-PET to perfusion CT. METHODS Twenty-four VX2 carcinoma tumors implanted in bilateral back muscles of 12 rabbits were evaluated. Serial concurrent perfu...
