Comparison of encirclage and cryotherapy with argon laser in the management of traumatic cyclodialysis cleft

引用

International Journal of Ophthalmology(English edition) 2019年第1期12卷 165-168页

作者： Gitanjli Sood Vinata Rajendran Ronnie George Tarun Sharma rajiv Raman Shri Bhagawan Mahavir Vitreo Retinal Services Sankara Nethralaya Department of Glaucoma Medical Research FoundationSankara NethralayaChennai

The study compared anatomical and functional outcome of a novel technique of encirclage and cryotherapy with the conventional argon laser in the management of traumatic cyclodialysis cleft in 19 patients(10: encirclage and 9: argon laser). The postoperative anatomical success was taken as rise in intraocular pressure(IOP) more than 6 mm Hg or the closure of cleft on gonioscopy or ultrasound biomicroscopy(UBM). Visual outcome was measured as change in logMAR visual acuity. Traumatic cataract and hypotony were present in majority. IOP>6 mm Hg was noted in 90% of encirclage group and in 77.70% of argon laser group. Two cases had non-closure of cleft. Encirclage is comparable to argon laser in terms of anatomical and functional success with possible advantage of single procedure and use in cases with failed laser.

Squamous Papilloma:Case Report and Review of Literature

Patil Dental College and Hospital Department of Oral Maxillofacial Pathology Dr. D. Y. Patil Dental College and Hospital

Squamous papillomas are common lesions of the oral mucosa with a predilection for the mucosa of the hard and soft palate. As an oral lesion,it raises concern because of its clinical appearance,which may mimic exophytic carcinoma,verrucous carcinoma or condyloma acuminatum. Its pathogenesis is related to human papilloma virus but there is controversy regarding its viral origin. We present a case of squamous papilloma presenting as oral lesion along with a review of the literature.

Improved dielectric and electro-optical parameters of nematic liquid crystal doped with magnetic nanoparticles

引用

Chinese Physics B 2019年第3期28卷 223-229页

作者： Geeta Yadav Govind Pathak Kaushlendra Agrahari Mahendra Kumar Mohd Sajid Khan V S Chandel rajiv Manohar Liquid Crystal Research Laboratory Department of PhysicsUniversity of LucknowLucknow 226007India

This study investigates the effect of magnetic nanoparticles(NPs) on the weakly polar nematic liquid crystal(NLC).Different parameters of dielectric data were measured for both the homeotropic and planar aligned samples as a function of frequency and temperature and the substantial changes have been noticed for the doped systems. Dielectric permittivity has been increased after the dispersion of magnetic NPs in the pure NLC. Dielectric anisotropy has also been influenced by incorporating the magnetic NPs with the NLC molecules. These results were attributed to the dipole–dipole interaction between the magnetic nanoparticles and nematic liquid crystal molecules. Electro-optical study indicated the faster rise time and fall time of the doped systems as compare to pure NLC. Threshold voltage has been calculated and found to be decreased for the doped systems. Moreover, we have also calculated the rotational viscosity and the splay elastic constant for pure and the doped systems. Both the rotational viscosity and splay elastic constant of the doped systems are found to be considerably lower than those of pure NLC. Change in these properties has been explained on the basis of molecular disturbances created by the interaction between the magnetic nanoparticle and LC director. This study reveals that the inclusion of magnetic NPs in weakly polar NLC can be useful to enhance the basic properties of the weakly polar NLC and make it a promising material for many display applications.
