Silicone pressure-sensitive adhesives compositions contain a polydimethylsiloxane and a silicone resin, which can enhance the instant bonding ability and bonding strength of the adhesive. In this study, silicone resin was designed to have a low molecular weight and a highly nonpolar chemical structure. The silicone resin was applied to silicone pressure-sensitive adhesives. The molecular struct...

BACKGROUND This study aimed to investigate the efficacy and safety of 3 nasal packing products (silicone tube, Beschitin-F, and Aquacel1-Ag) after functional endoscopic sinus surgery (FESS) for chronic rhinosinusitis (CRS) patients in China. MATERIAL AND METHODS Sixty-six CRS patients undergoing FESS surgery were randomly divided into 3 groups (22 patients in each group): the silicone tube grou...

The effect of liquid and solid transfer vectors (silicone oil and Desmopan, respectively) on the gaseous interfacial area (a(g)) was evaluated in a two-phase partitioning bioreactor (TPPB) using fresh mineral salt medium and the cultivation broth of a toluene degradation culture (Pseudomonas putida DOT-T1E cultures continuously cultivated with and without silicone oil at low toluene loading rat...

We show that the chemical structures of silicone oils can have an important role in the giant electrorheological (GER) effect. The interaction between silicone oils and solid nanoparticles is found to significantly influence the ER effect. By increasing the kinematic viscosity of silicone oils, which is a function of siloxane chain length, sol-like, gel-like and clay-like appearances of the con...

Biomaterial-centered infection is a dreaded complication associated with the use of biomedical implants. In this paper, the antimicrobial activity of silicone rubber with a covalently coupled 3-(trimethoxysilyl)-propyldimethyloctadecylammonium chloride (QAS) coating was studied in vitro and in vivo. Gram-positive Staphylococcus aureus ATCC 12600, Staphylococcus epidermidis HBH, 102, and Gram-ne...

BACKGROUND The aim of the study was in vitro assessment and comparison of the antimicrobial activity of three types of silicone oils used in ophthalmic surgery. METHODS The silicone oils (Arciolane 1300 centistokes, Arciolane 5500 centistokes and Oxane Hd, heavy silicone oil) were inoculated with microbes common in endophthalmitis and their growth was observed continuously. Control tests of m...

Silicone elastomer medical implants are ubiquitous in medicine, particularly for breast augmentation. However, when these devices placed within the body, disruption of natural biological interfaces occurs, which significantly changes native energy-dissipation mechanisms living systems. These new can introduce non-physiological contact pressures and tribological conditions that provoke inflammat...

Introduction: MR imaging of breast implants has emerged as an important tool basically due to two reasons a) the difficulty to diagnose lesions in augmented or reconstructed breasts solely using mammography and ultrasound b) the necessity to assess the intactness of the implant on a regular basis [1]. A conventional complete exam of a patient with silicone implants to detect possible ruptures c...

3. The adhesive backed 'hook' Velcro ® is adhered to the thermoplastic , passed under the distal phalanx and wrapped around the spring on the other side of the Ligamentotaxor ® device, fastening to the loop Velcro ® underneath, thereby supporting the distal phalanx (Fig 2). DISCUSSION Prompt recognition of extensor lag and treatment using this frame modification arrests progression of the probl...
