BACKGROUND/AIM The authors studied the expression of cancer stem cell surface marker, ABCG2, and neural stem cell marker, MCM2, in retinoblastoma and correlated clinicopathologically. METHODS Among 39 retinoblastomas, 18 tumours were not subjected to preoperative/postoperative chemotherapy, 15 tumours underwent postoperative chemotherapy, and six tumours(More)
Progesterone plays a key role in ovarian cycle-related synaptic plasticity and neuronal excitability. Progesterone receptors (PRs), which mediate the cellular actions of progesterone, are expressed in the hippocampus and other limbic regions, but their functional significance remains unknown. Here, we report a novel role of PRs as crucial mediators in the(More)
OBJECTIVE To study the oxygen saturation profile in normal Asian Indian eyes. DESIGN A cross sectional prospective study. SUBJECTS Ninety eight consecutive patients presenting to our hospital with best corrected distance visual acuity (BCVA) of 20/20 and a normal ophthalmic examination were included in the study. Patients having any ocular or systemic(More)
PURPOSE To study the oxygen-saturation profiles in RP and macular dystrophies and compare them with age-matched healthy controls. METHODS In a cross-sectional prospective study, 62 subjects with RP, 23 with macular dystrophies, and 78 controls were enrolled, and retinal oximetry was performed with the Oxymap T1 retinal oximeter. The images were analyzed(More)
PURPOSE To study whether there exists a relationship between retinal nerve fiber layer thickness and oxygen saturation and to identify whether perivascular thickness (pRNFL) or quadrant thickness (qRNFL) has a stronger correlation. METHODS Patients without any detectable ocular abnormality on complete ophthalmic evaluation underwent non-invasive(More)
According to a report by Frost and Sullivan in 2007, revenues for non-AFIS fingerprint devices in notebook PC's and wireless devices is anticipated to grow from $148.5 million to $1588.0 million by 2014, a compound annual growth rate of 40.3% [1]. The AFIS market has a compound annual growth rate of 15.2% with revenues of $445.0 million in 2007. With the(More)
The present study was carried out with the objectives of genotyping Pneumocystis jirovecii at three distinct loci, to identify the single nucleotide polymorphisms (SNPs), and to study its clinical implications in patients with Pneumocystis pneumonia (PCP). Analysis of genetic diversity in P. jirovecii from immunocompromised patients was carried out by(More)
