Melanins are high molecular weight hydrophobic pigments that have been studied for their role in the virulence of fungal pathogens. We investigated the amount and type of melanin in 20 isolates of Aspergillus spp.; A. niger (n = 3), A. flavus (n = 5), A. tamarii (n = 3), A. terreus (n = 3), A. tubingensis (n = 3), A. sydowii (n = 3). Aspergillus spp. were(More)
Dissimilarities in ocular physiopathology exist between human males and females. These differences can be observed in the lacrimal and other eye-associated glands, the ocular surface, the crystalline lens, and the retinochoroid complexes. Literature on the subject revealed that because of sex steroid hormone (estrogen, progesterone, and androgen) actions,(More)
PURPOSE To evaluate contrast sensitivity and glare disability after implantation of an AcrySof IQ Natural SN60WF aspherical intraocular lens (IOL) (Alcon Laboratories). SETTING Iladevi Cataract & IOL Research Centre, Ahmedabad, India. METHODS One hundred twenty consecutive patients who had phacoemulsification in a prospective triple-masked trial were(More)
PURPOSE To analyze factors contributing to uncorrected visual acuity of at least 6/12 for distance and at least J4 for near (pseudoaccommodation) after monofocal intraocular lens (IOL) implantation. SETTING Iladevi Cataract and IOL Research Center, Ahmedabad, India. METHODS In a case-controlled study of 30 eyes (30 patients) that had(More)
BACKGROUND Cataract is responsible for about 10% blindness among children in India. Etiology of cataract is not well defined especially for childhood cataracts and epidemiological data for Indian population is not available in details. AIM This study was performed to survey the causes of childhood cataracts and to identify the preventable factors in four(More)
PURPOSE To determine whether pseudophakic astigmatism is a desirable goal, and if so, which one is better: against-the-rule (ATR) or with-the-rule (WTR). METHOD Eyes were included only if they had an uncorrected vision > or = 6/18 and N/18. Three groups, of 40 patients each were evaluated: group 1, pseudophakes with neutral astigmatism; group 2, with ATR(More)
The Cassini Imaging Science Subsystem (ISS) began observing Saturn in early February 2004. From analysis of cloud motions through early October 2004, we report vertical wind shear in Saturn's equatorial jet and a maximum wind speed of approximately 375 meters per second, a value that differs from both Hubble Space Telescope and Voyager values. We also(More)
Calcium and Ca-dependent enzymes play specific role in the development of human cataracts. Entry of Ca2+ into the lens epithelial cells (LEC) is highly regulated by quantum of receptors. The Ca2+ level controls homeostasis and growth of entire lens. Intracellular overload of Ca2+ in the LEC trigger a series of events such as activation of Ca-dependent(More)
PURPOSE To evaluate visual axis opacification after AcrySof intraocular lens (IOL) (Alcon) implantation in pediatric eyes. SETTING Iladevi Cataract and IOL Research Centre, Ahmedabad, India. METHODS This prospective study evaluated 103 consecutive eyes of 72 children with congenital cataract. Two groups were formed based on age at surgery: Group 1,(More)
PURPOSE To evaluate the intraoperative performance and postoperative outcomes after microcoaxial phacoemulsification. SETTING Iladevi Cataract & IOL Research Centre, Ahmedabad, India. METHODS A prospective observational case series comprised 84 eyes with age-related uncomplicated cataract having microcoaxial phacoemulsification through a 2.2 mm clear(More)
