Ramadan fasting has been a major concern among researchers considering the theoretically imposed risk on patients with diabetes mellitus due to prolonged fasting. Studies indicate that the knowledge and practices of physicians do not comply with the proposed recommendations in this regard in many cases. This study aimed to explore the viewpoints and attitudes of physicians toward the management...

BACKGROUND Susac's syndrome (SuS) is an uncommon disease characterized by retinal microangiopathy that may be assessed more accurately with optical coherence tomography angiography (OCTA), a new imaging technique which provides a retinal microvasculature map. The purpose of this case report is to describe the multimodal imaging findings of SuS correlating OCTA with functional tests. CASE PRES...

Sulphonylureas (SUs) are widely used glucose-lowering agents in type 2 diabetes mellitus (T2DM) with apparent declining efficacy over time. Concerns have been raised from observational retrospective studies on the cardiovascular (CV) safety of SUs but there are few long-term data on CV outcomes from randomized controlled trials (RCTs) involving the use of this class of agents. Most of the obser...

This paper considers a cognitive radio (CR) network, in which the unlicensed (secondary) users (SUs) are allowed to concurrently access the spectrum allocated to the licensed (primary) users, provided that the interference of SUs with the primary users (PUs) satisfies certain constraints. It is more general and owns a stronger challenge to ensure the quality of service (QoS) of PUs, as well as ...

Cotton (Gossypium hirsutum L.) seed develops single-celled long fibres (lint) from the seed-coat epidermis at anthesis. Previous studies have shown that the initiation and rapid elongation of these fibres requires the expression of sucrose synthase (Sus) and, potentially, a transient closure of plasmodesmata. This study extends the previous work to examine the patterns of Sus expression and pla...

BACKGROUND Heart surgery has developed with increasing patient complexity. OBJECTIVE To assess the use of resources and real costs stratified by risk factors of patients submitted to surgical cardiac procedures and to compare them with the values reimbursed by the Brazilian Unified Health System (SUS). METHOD All cardiac surgery procedures performed between January and July 2013 in a tertia...

Sulfonylureas (SUs) are widely used insulin secretagogues, but they have adverse effects including hypoglycemia and secondary failure. Fasiglifam/TAK-875, a selective GPR40 agonist, enhances glucose-stimulated insulin secretion and improves hyperglycemia. In the present study, we compared the in vivo glucose-lowering effects of fasiglifam with SUs. The risk of secondary failure of fasiglifam an...

Intraspecific variation and trade-off in aerobic and anaerobic traits remain poorly understood in aquatic locomotion. Using gilthead sea bream (Sparus aurata) and Trinidadian guppy (Poecilia reticulata), both axial swimmers, this study tested four hypotheses: (1) gait transition from steady to unsteady (i.e., burst-assisted) swimming is associated with anaerobic metabolism evidenced as excess p...
