BACKGROUND Studies have suggested that the Calpain-10 gene polymorphisms may play a role in polycystic ovary syndrome (PCOS) susceptibility. Thus, the aim of the present study was to evaluate the possible association between three single nucleotide polymorphisms (SNPs) in the calpain-10 gene (UCSNPs -43, -19, and -63) and polycystic ovary syndrome (PCOS) in(More)
Homeostatic mechanisms stabilize neural circuit function by keeping firing rates within a set-point range, but whether this process is gated by brain state is unknown. Here, we monitored firing rate homeostasis in individual visual cortical neurons in freely behaving rats as they cycled between sleep and wake states. When neuronal firing rates were(More)
Propolis is a polyphenol-rich resinous substance extensively used to improve health and prevent diseases. The effects of polyphenols from different sources of propolis on atherosclerotic lesions and inflammatory and angiogenic factors were investigated in LDL receptor gene (LDLr-/-) knockout mice. The animals received a cholesterol-enriched diet to induce(More)
During the 2008 Congress of the International Society for Peritoneal Dialysis, academic nephrologists, nephrology societies, and government officials from Colombia, Brazil, Argentina, Chile, Central America, Ecuador, and Mexico participated in a roundtable discussion on the Economics of Dialysis and Chronic Kidney Disease in Latin America. The main focus(More)
In Chile the reimbursement/patient/year for chronic peritoneal dialysis (PD) is US$14,654 and for chronic hemodialysis (HD) US$10,909. However, no study comparing global (direct plus indirect) costs has been performed in our country. Our research objective was to compare global costs and quality of life between the two therapies. Patients (n = 159) from(More)
BACKGROUND The excretion of cholesterol from liver and intestine is regulated by ATP-binding cassette half-transporters ABCG5 and ABCG8. Polymorphisms in their genes have been related to higher levels of plasma lipids. Thus, the aim of the present study was to evaluate the possible association between the 1950C > G (ABCG5) and the 251A > G (ABCG8)(More)
BACKGROUND AND OBJECTIVE Chronic hemodialyzed patients have a low level of aerobic capacity, caused by the pathologies concomitant to renal insufficiency, according with a low level of physical activity. One of the factors that would contribute to this level of aerobic capacity is the L-carnitine deficit on skeletal muscle. However, the value of the(More)
The most successful therapy for acute liver failure is liver transplantation. However, due to the low number of donors, organ support therapies need to be used as a bridge to liver transplantation. Molecular Adsorbents Recirculating System (MARS) is a dialysis treatment that uses a recirculating dialysate containing albumin. This allows the removal of both(More)
Chronic peritoneal dialysis (PD) therapy is equally efficient as hemodialysis while providing greater patient comfort and mobility. Therefore, PD is the treatment of choice for several types of renal patients. During PD, a high-glucose hyperosmotic (HGH) solution is administered into the peritoneal cavity to generate an osmotic gradient that promotes water(More)
A chest X-ray has been routinely used to evaluate possible complications of a catheter installed for hemodialysis. The objective of the present study was to evaluate the utility of routine chest X-ray to detect complications derived from the installation of temporary catheters through a jugular vein access. We studied prospectively 95 successive jugular(More)
