Abstract—Ultraviolet photocatalytic oxidation (UV-PCO) technology has been recommended as a green approach to health indoor environment when it is integrated into mechanical ventilation systems for inorganic and organic compounds removal as well as energy saving due to less outdoor air intakes. Although much research has been devoted to UV-PCO, limited information is available on the UV-PCO beh...

PURPOSE Posterior capsular opacification (PCO) is a common long-term complication of modern cataract surgery. We have shown that Zebularine, an inhibitor of DNA methylation, suppresses transforming growth factor-β (TGFβ)-induced lens epithelial cells (LECs)-myofibroblasts transdifferentiation. The purpose of this study is to evaluate the role that Zebularine plays in the inhibition of PCO patho...

BACKGROUND Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disorder associated with ovulatory dysfunction, abdominal obesity, hyperandrogenism, hypertension, and insulin resistance. METHODS Our objectives in this study were (1) to estimate sympathetic-adrenal medullary (SAM) activity by measuring mean systolic blood pressure (MSAP) in rats with estradiol valerate (EV)-in...

Pseudovivipary is an asexual reproductive strategy exhibited by some arctic/alpine grasses in which leafy plantlets are produced in place of seeds, with genetic conservation an advantage for stress tolerators in these nutrient-poor habitats. Photosynthetic metabolism and the development of this reproductive system were investigated under varying nutrient availability and predicted future CO(2) ...

PCO affects about 10% of females. Increase in the burden of PCOS has led to a considerable amount of research into its risk factors, pathophysiology and the management [2]. There have been numerous theories that have been put forward for describing the etiology for an ovulation in PCO including; an excess of small antral follicles, hyperandrogenaemia, hyperinsulinaemia and dysfunctional feedbac...

EDITORIAL It is known that pseudophakia is a very frequent condition in ophthalmology. The visual benefit obtained after a cataracts operation can diminish in time due to the progressive development of a posterior capsule opacification (PCO). Even though surgical techniques and the design and materials of intra-ocular lenses have been continuously modified, PCO continues to be the most frequent...

OBJECTIVE Surface roughness parameters of various intraocular lenses (IOLs) biomaterials using atomic force microscopy (AFM) are compared. Variation, if any, in the micro-roughness properties of different IOLs made up of the same biomaterial is also explored. Retrospective analysis of posterior capsular opacification (PCO) incidence has been followed up for a period of four years post IOL impla...

DOS Times Vol. 12, No. 4 October, 2006 Posterior capsule opacification (PCO) and posterior chamber intraocular lens (PC IOL) decentration still remain two major complications of successful extracapsular cataract surgery (ECCE) or phacoemulsification. Ridley, who performed the first intraocular lens implantation in 1949, himself noted these complications in his earliest patients.7 In his initial...

To calculate cardiac output by the indirect Fick principle, CO(2) concentrations (CCO(2)) of mixed venous (Cv(CO(2))) and arterial blood are commonly estimated from PCO(2), based on the assumption that the CO(2) pressure-concentration relationship (PCO(2)-CCO(2)) is influenced more by changes in Hb concentration and blood oxyhemoglobin saturation than by changes in pH. The purpose of the study ...
