a numerical study has been done through an al2o3–water in a double lid-driven  square  cavity with various  inclination  angles  and discrete heat sources. the top and right moving walls are at low temperature. half of  the  left and bottom walls are  insulated and  the  temperatures of the other half are kept at high. a large number of simulations for a wide  range  of richardson  number  of  ...

In an attempt to restrict drug absorption from suppositories to only the lower rectum, mucoadhesive lidocaine (LID) suppositories were prepared using WitepsolR H-15 as a base, and CarbopolR 934p (CP) and white beeswax (WAX) as additives. CP has a mucoadhesive property and WAX gives the suppositories stiffness. The suppositories containing 109{(, CP and 20% WAX stayed in the lower recta of rats ...

Various surgical techniques have been proposed for treating distichiasis in dogs. A technique involving eyelid splitting and double freeze-thaw cryotherapy with anterior lamellar recession was evaluated. A 3 year old, female, Staffordshire bull terrier was referred for bilateral distichiasis. There were bilateral multiple distichiasis of the upper lids, more severe on the right lid with double ...

Pseudomonas aeruginosa lipase is a 29-kDa protein that, following the determination of its crystal structure, was postulated to have a lid that stretched between residues 125 and 148. In this paper, using molecular dynamics simulations, we propose that there exists, in addition to the above-mentioned lid, a novel second lid in this lipase. We further show that the second lid, covering residues ...

purpose: to compare the results of two different methods of frontalis suspension using fascia lata in congenital ptosis. methods: in a randomized clinical trial, double triangle sling was compared with single triangle sling using fascia lata. eight patients with unilateral and 11 patients with bilateral congenital ptosis were randomly assigned for each procedure. results: there was no statistic...

Aim: To compare the effect of single rhomboid and double rhomboid frontalis suspension using 2 mm silicon band on upper lid contour in ptosis surgery. Methods: This randomized control study was conducted at the Department of Ophthalmology, Nishtar Hospital, Multan from March 2011 to March 2014. A total of 40 patients with unilateral ptosis were included in the study. Patients were divided into ...

Fluctuating double vision and ptosis are the hallmarks of extraocular muscle weakness in myasthenia gravis (MG). On sustained upward gaze, ptosis usually increases temporarily. The first description of using this fatigue sign has been attributed to the Scottish neurologist John Simpson. Cogan added his lidtwitch sign to the diagnostic bedside armamentarium.1 For many years, we have applied a fa...
