PURPOSE To compare the rotational stability and posterior capsule opacification (PCO) rate in eyes with a 1-piece or 3-piece acrylic intraocular lens (IOL). SETTING Department of Ophthalmology, Medical University of Vienna, Vienna, Austria. DESIGN Prospective randomized masked clinical trial. METHODS Patients with age-related cataract received a plate-haptic acrylic IOL (Acri.Smart 46S) i...

Ocean acidification threatens organisms that produce calcium carbonate shells by potentially generating an under-saturated carbonate environment. Resultant reduced calcification and growth, and subsequent dissolution of exoskeletons, would raise concerns over the ability of the shell to provide protection for the marine organism under ocean acidification and increased temperatures. We examined ...

INTRODUCTION We aimed to identify the variables associated with ovarian hyperstimulation in Asian patients and compare them with western standards. METHODS This is a retrospective case record analysis of 79 patients with ovarian hyperstimulation at a tertiary restructured hospital. RESULTS Gonadotropin doses resulting in hyperstimulation did not vary between long and antagonist cycles in wo...

OBJECTIVE(S) PCOS (polycystic ovary syndrome) produces symptoms in approximately 5% to 10% of women of reproductive age (12-45 years old). It is thought to be one of the leading causes of female subfertility. This study aimed to confirm the role of nutrition containing omega-3 (polyunsaturated fatty acid) on control of experimental PCO induced by estradiol-valerat in rats. MATERIALS AND METHO...

PURPOSE To evaluate posterior capsule opacification (PCO) in humans after cataract surgery with intraocular lens (IOL) implantation, by using optical coherence tomography (OCT-1). METHODS Sixty-six eyes with PCO and 20 eyes with a normal posterior capsule were analyzed. A 3-mm-long horizontal scan of the posterior capsule was obtained. Measurements at three points and their average were recor...

Purpose To evaluate the influence of Intraocular Lens (IOL) material and design on Posterior Capsule Opacification (PCO) and Neodymium-YAG (Nd-YAG) rates in eyes implanted with different Posterior Chamber Intraocular Lenses (PC IOLs) designs at the end of uncomplicated cataract surgeries. Setting Oculus Eye Clinic, Bucharest, Romania. Design Retrospective, observational study. Methods Thi...

conclusions hemodialysis exacerbates oxidative stress and conformational changes of hb in patients with diabetes on hemodialysis. the frap value can be used as a positive determinant, while pco and hb derivatives can be used as negative determinants of oxidative stress in patients with diabetes. background diabetes is associated with an increased generation of reactive oxygen species (ros), whi...

two-hundred and seventeen subjects underwent transvaginal ultrasound -17 (8%) had unilateral polycystic ovary (pco). twelve percent of subjects with unilateral scan-pea had oligomenorrhea, 24% were amenorrheic, 23% were hirsute and 29% had acne. biochemical parameters were compared between subjects with unilateral scan- pco and those with bilateral scan- pco (n=200) as well as a group of scan-n...

Kernel density estimation is a well known method involving smoothing parameter (the bandwidth) that needs to be tuned by the user. Although this has been widely used, bandwidth selection remains challenging issue in terms of balancing algorithmic performance and statistical relevance. The purpose paper study recently developed method, called Penalized Comparison Overfitting (PCO). We first prov...
