Plants respond to a reduction in the red/far-red ratio (R:FR) of light, caused by the proximity of other plants, by initiating morphological changes that improve light capture. In Arabidopsis, this response (shade avoidance syndrome, SAS) is controlled by phytochromes (particularly phyB), and is dependent on the TAA1 pathway of auxin biosynthesis. However, when grown in real canopies, we found ...

Background. The aim of this study is to present a method of lid laxity evaluation and investigate whether there is an association between floppy eyelid syndrome (FES) and body mass index (BMI) in sleep apnea syndrome (SAS) patients compared to normal subjects. Method. A total of 135 participants (81 patients with SAS and 54 normal subjects) had a full ophthalmologic examination. The presence of...

Background The surgical Apgar score (SAS) is a 10-point scale using the lowest heart rate, lowest mean arterial pressure, and estimated blood loss (EBL) during surgery to predict postoperative outcomes. The SAS has not yet been validated in liver transplantation patients, because typical blood loss usually exceeds the highest EBL category. Our primary aim was to develop a modified SAS for liver...

Introduction: Autonomic heart rate (HR) control evaluated by means of HR variability measures has been widely accepted as important information of cardiovascular function being a marker of sudden death. Methods: Polysomnography was performed in 405 CAD pts (mean age 60.7 yr.) pts, including 200 pts with CHF (mean age 63.4 yr.). Sleep apnea syndrome (SAS) was observed in 46 pts (mean age 64.2 yr...

Formation of the microtubule-based centriole is a poorly understood process that is crucial for duplication of the centrosome, the principal microtubule-organizing center of animal cells . Five proteins have been identified as being essential for centriole formation in Caenorhabditis elegans: the kinase ZYG-1, as well as the coiled-coil proteins SAS-4, SAS-5, SAS-6, and SPD-2 . The relationship...

BACKGROUND Decreased cerebral glucose metabolism has been reported in patients with sleep apnea syndrome (SAS), but it has yet to be decided whether cerebral glucose metabolism in SAS can be altered by continuous positive airway pressure (CPAP) treatment. OBJECTIVE The aim of this study was to evaluate cerebral glucose metabolism changes in patients with SAS after CPAP treatment. METHODS Th...

Centrioles are highly ordered structures that organize two key cellular organelles: the centrosome and the cilium. Defects in both organelles are now firmly linked to a wide variety of human diseases1. Centrioles are composed of nine blade-like microtubule triplets, arranged at the end of nine spokes that radiate from a central hub (Fig. 1a). The central hub and spokes are collectively referred...
