The laryngeal mask airway (LMA) was invented by Dr. Archie Brain at the London Hospital, Whitechapel, in 1981. Dr. Brain's main objective for the LMA was that it would provide a better method of maintaining a patient's airway than by face mask. Also, the LMA would be less hemodynamically stressful than with insertion of an endotracheal tube. The LMA consists of a silicone rubber tube connected ...

Bone marrow-derived cells (BMCs) are multipotent cells that have the potential to differentiate into bone, cartilage, fat, muscle, or neuronal lineages such as neurons and glial cells. A silicone tube model containing reverse-pedicled sural vessels was created in the sciatic nerves of Lewis rats. About 1 x 10(7) BMCs, removed from the bone marrow of synergetic rat femurs and cultured in vitro, ...

Dear Editor, The Baerveldt glaucoma implant (BGI; Abbott Laboratories, Abbott Park, IL, USA) is a widely used glaucoma drainage device for intraocular pressure (IOP) control. Although the BGI effectively controls IOP, the possibility of postoperative ocular hypotony owing to excessive aqueous drainage and tube-related complications still remains [1,2]. Given that the amount of aqueous drainage ...

Aim: To present the long-term results of bicanalicular silicone tube intubation combined with external dacryocystorhinostomy (EDRS) in-patient nasolacrimal duct obstruction (NLDO)
 Methods: Long-term 169 eyes patients who underwent between January 2010 and December 2020 in our clinic were evaluated, retrospectively. On postoperative 1st day, 10th month, 3rd 6th 9th 12th last visits, evalua...

A study of nerve regeneration through a 1cm defect in the peroneal component of the sciatic nerve was performed on sixteen rabbits. Either silicone or polytetrafluoroethylene (PTFE) tubes or nerve graft were used to bridge the defect and the opposite limb was not operated upon. The rabbits that underwent nerve grafting had favourable findings. In the PTFE group, a nerve-like structure was seen ...

A gas-permeable silicone membrane bioreactor was used to cultivate the biofilm under hydrogenotrophic condition for reductive dechlorination of 2-chlorophenol (2-CP). The anaerobic sludge obtained from a swine wastewater treatment plant was immobilized by polyvinyl alcohol (PVA) so as to form a biofilm on the surface of the silicone tube. After acclimating for about 4 months, the bioreactor sho...
