BACKGROUND: More than 35 substances released from composite fillings have been identified. Among these, basic monomers and the so-called co-monomers are most often reported. The substances released from polymer-based materials demonstrate allergenic, cytotoxic, genotoxic, mutagenic, embryotoxic, teratogenic, and estrogenic properties. OBJECTIVES: The aim of this study was to measure the amounts of triethylene glycol dimethacrylate (TEGDMA) and urethane dimethacrylate (UDMA) monomers released from composite dental fillings to citrate-phosphate buffer with the pH of 4, 6, 8 after 24 h and 6 months from the polymerization...

Seedless synthesis of Pd nanorods and their self-assembly into the layered smectic ordering is described. Aqueous Pluronic triblock copolymers (14.3% - 35.7%) are used as a soft template along with cetyltrimethylammonium bromide (CTAB) for inducing one-dimensional growth of Pd nanorods. Pluronic triblock copolymers are probably the most used polymer surfactants, and they are composed of PEO(polyethylene oxide)-PPO(polypropylene oxide)-PEO triblocks. Neither pH adjustment, nor AgNO3, nor other additives such as polyvinyl pyrolidone, and ethylene glycol are required to obtain Pd nanorods...

There is a need for soft actuators in various biomedical applications in order to manipulate delicate objects such as cells and tissues. Soft actuators are able to adapt to any shape and limit the stress applied to delicate objects. Conjugated polymer actuators, especially in the so-called trilayer configuration, are interesting candidates for driving such micromanipulators. However, challenges involved in patterning the electrodes in a trilayer with individual contact have prevented further development of soft micromanipulators based on conjugated polymer actuators...

We report a case of a 68-year-old gentleman, found to have a right hilar soft tissue mass whilst undergoing CT staging for prostate cancer. MRI imaging showed a heterogenous, enhancing solid mass without evidence of fat content. A linear probe endobronchial ultrasound-guided transbronchial needle aspiration was performed using a 19G needle. This confirmed the diagnosis of a benign chondroid hamartoma, avoiding the need for more invasive surgical biopsy.

In the past decades, dietary guidelines focused on reducing saturated fat as the primary strategy for cardiovascular disease prevention, neglecting the many other potential effects of diet on health, in particular the harmful effects of sugar. A greater intake of soft drinks (sugar-sweetened beverages), for example, is associated with a 44% increased prevalence of metabolic syndrome, a higher risk of obesity, and a 26% increased risk of developing diabetes mellitus. Carbohydrates comprise around 55% of the typical western diet, ranging from 200 to 350 g/day in relation to a person's overall caloric intake...

A good long-term outcome following a total knee arthroplasty relies on restoration of the mechanical axis and effective soft tissue balancing of the prosthetic knee. Arthroplasty surgery in patients with secondary osteoarthritis of the knee with an extra-articular tibial deformity is a complex and challenging procedure. The correction of mal-alignment of the mechanical axis is associated with unpredictable result and with higher revision rates. Single-staged deformity correction and replacement surgery often result in the use of constraint implants...

Local anesthesia is administered to control pain, but it may induce fear and anxiety. Root planing is a non-surgical periodontal therapy; however, when it is performed in an extensive manner, some tissue removal is inevitable. Notably, this removal may be so painful that local anesthesia is required to be administered to the area scheduled for the treatment. Although patients tend to accept root planing easily, they frequently express a fear of local anesthesia. Intraosseous anesthesia (IA) is an intraosseous injection technique, whereby local anesthetic is injected into the cancellous bone supporting the teeth...

Background: Morel-Lavallee lesions (MLLs) are rare internal degloving injuries typically caused by blunt traumatic injuries and most commonly occur around the hips and in association with pelvic or acetabular fractures. MLL is often overlooked in the setting of poly-trauma; therefore, clinicians must maintain a high degree of suspicion and be familiar with the management of such injuries, especially in obese poly-trauma patients. Case presentation: We present a 30-year-old female pedestrian struck by a motor vehicle who sustained multiple long bone fractures, a mesenteric hematoma, and full-thickness abdominal skin friction burn which masked a significant underlying abdominal MLL...

Castleman's disease (CD) is a lymphoproliferative abnormality, also referred to as giant lymph node hyperplasia or follicular lymphoid hyperplasia. The occurrence of CD in the liver is rare. Radiological diagnosis of hepatic CD by computed tomography (CT) and magnetic resonance imaging (MRI) remains difficult. On imaging, hepatic CD is often expressed as a single, well-defined soft tissue lesion, with rare cystic degeneration and focal necrosis. The CD lesions appear as hypervascular with abundant cell proliferation on CT and MRI...
