In chronic heart failure (CHF), the abnormally large ventilatory response to exercise (VE/VCO(2) slope) has 2 conceptual elements: the requirement of restraining arterial partial pressure of carbon dioxide (pCO(2)) from increasing (because of an increased ratio between increased physiologic dead space and tidal volume [VD/VT]) and the depression of arterial pCO(2) by further increased ventilati...

The polycystic ovary syndrome (PCOS) is a heterogeneous condition, the pathophysiology of which appears to be both multifactorial and polygenic. The definition of the syndrome has been much debated. Key features include menstrual cycle disturbance, hyperandrogenism and obesity. There are many extra-ovarian aspects to the pathophysiology of PCOS, yet ovarian dysfunction is central. At a recent j...

PURPOSE To compare the rates of lens epithelial cell (LEC) migration and posterior capsule opacification (PCO) 1 and 3 years after sutureless small incision phacoemulsification and in-the-bag implantation of 2 acrylic polymer intraocular lenses (IOLs)-the AcrySof and MemoryLens-in fellow eyes of patients. SETTING Eye Clinic, Beyoğlu Education and Research Hospital, Istanbul, Turkey. METHODS...

The effects of UV-assisted TiO2-photocatalytic oxidation (PCO) inactivation of pathogenic bacteria (Escherichia coli O157:H7, Listeria monocytogenes, Salmonella typhimurium) in a liquid culture using different domains of UV irradiation (A, B and C) were evaluated. Structural changes in super-coiled plasmid DNA (pUC19) and genomic DNA of E. coli were observed using gel electrophoresis to demonst...

CONTEXT Obesity and insulin resistance (IR) may produce disturbances of left ventricular (LV) function. Obese women with polycystic ovary syndrome (PCO), characterized by hormonal and metabolic abnormalities, are thought to be at particularly increased cardiovascular risk. OBJECTIVES We sought to determine the influence of IR on LV function in obese young women with and without PCO and withou...

The UN Sustainable Development Goals (SDGs) cover subjects such as ending poverty, achieving gender equality, ensuring access to water, energy, and food, and protecting ecosystems. Every SDG includes wording that refers directly or indirectly to a population or community or organisms, humans or otherwise. Therefore, the Population and Community Ontology (PCO) plays a crucial role in defining th...

Lateral luxation of permanent teeth is a common injury, and the most frequent post-injury complications is Pulp Canal Obliteration (PCO) followed by pulp necrosis and root resorption. This report presents two different prognoses for symmetrical immature maxillary central incisors after lateral luxation in a 7-year-old boy. Both teeth were laterally luxated and the gingiva distal to the left inc...

PURPOSE To compare the rates of rapid posterior capsule opacification (PCO) formation in the first 3 months following femtosecond laser-assisted cataract surgery (FLACS) to manual anterior capsulorhexis. METHODS Retrospective review of 29 cases of FLACS, comparing the rates of PCO in the first 3 months following surgery to 50 consecutive cases of manual anterior capsulorhexis. RESULTS Seven...

AIM To compare the effectiveness and safety of pars plana capsulotomy and vitrectomy using 25-gauge tansconjunctival sutureless vitrectomy system and 20-gauge vitrectomy system for posterior capsule opacification (PCO) in pseudophakic children. METHODS Retrospectively study. Pars plana capsulotomy and vitrectomy using 25-gauge sutureless vitrectomy system was performed for PCO in the study gr...
