The 3D-QSAR method comparative molecular field analysis (CoMFA) involves the estimation of atomic partial charges as part of the process of calculating molecular electrostatic fields. Using 30 data sets from the literature the effect of using different common partial charge calculation methods on the predictivity (cross-validated R2) of CoMFA was studied.(More)
This paper provides the information regarding the improvement in capacity and signal strength with the implementation of adaptive beamfoming algorithms (LMS and SMI) in adaptive antenna arrays.In this a beamforming algorithm is analyzed for flexible side lobe adjustment. The algorithm places a very low side lobe level over a large width in the beam pattern.(More)
2D and 3D QSAR techniques are widely used in lead optimization-like processes. A compilation of 40 diverse data sets is described. It is proposed that these can be used as a common benchmark sample for comparisons of QSAR methodologies, primarily in terms of predictive ability. Use of this benchmark set will be useful for both assessment of new methods and(More)
A 52-years-old female presented with a history of a painless, progressive swelling in the left lower eyelid of one-year duration. The lesion was excised twice as a chalazion and recurred. Excisional biopsy of the mass was performed and histopathological findings were consistent with those of trichilemmal cyst. We report a rare case of trichilemmal cyst of(More)
A 40-year-old lady presented with severe endothelial cell loss in both eyes 14 years after angle-supported phakic intraocular lens (AS PIOL) implantation. The left eye had severe corneal edema with bullous keratopathy. The right eye had markedly reduced endothelial cell count (655 cells/mm 2 ) although the cornea was clear. She underwent simultaneous(More)
A 44-year-old man presented 28 days after cataract surgery (phacoemulsification) in right eye with multiple pinpoint infiltrates in posterior stroma at cataract surgery wound site. Visual acuity was 20/60. Corneal scraping from the floor of the corneal tunnel revealed fungus which was later identified to be Aspergillus flavus. The patient was started on(More)
Herein, we present a case report of post-TURP (transurethral resection of prostate) recurrent severe hematuria due to right internal iliac artery pseudoaneurysm protruding into bladder lumen. A 60-year-old male presented with recurrent massive hematuria following TURP done elsewhere 15 days before. His hemoglobin was 4 gm/dL after 13 units of blood(More)
Toxoplasmosis is a relatively rare complication in renal transplant patients and can pose diagnostic challenges, especially when it manifests as an ocular inflammation. Authors hereby report an unusual case of a 57-year-old male who developed retinochoroidal toxoplasmosis after 15 years of renal transplant, the diagnoses of which were challenging as the(More)
A 38-year-old woman presented with corneal decompensation in left eye secondary to irido-corneal endothelial (ICE) syndrome. She underwent simultaneous Descemet's stripping endothelial keratoplasty (DSEK) and clear lens extraction with posterior chamber intraocular lens implantation. The surgery was accomplished comfortably without rupture of peripheral(More)
We performed endothelial keratoplasty (EK) in three eyes of two siblings (2.5 years, male and 3.5 years, female) with congenital hereditary endothelial dystrophy (CHED) and report the intraoperative and postoperative difficulties. Repeated iris prolapse, apprehension of crystalline lens touch due to positive vitreous pressure, and need for frequent air(More)
