BACKGROUND Despite a significant improvement in the management of chronic kidney disease (CKD), its incidence and prevalence has been increasing over the years. Progressive renal fibrosis is present in CKD and involves the participation of several cytokines, including Transforming growth factor-β1 (TGF-β1). Besides cardiovascular diseases and infections, several studies show that Vitamin D stat...

[1] New spacecraft data, especially MOLA topography, reveal important characteristics of Alba Patera that were either unknown or poorly resolved in previous data sets. The major and consistent breaks of slope and the specific pattern of lava flows within a broad region around Alba Patera permit division of this area into two major parts that appear to be related to different episodes of volcani...

Abstract: Introduction: The increased overjet in Class II Division 1 malocclusion subjects may be due to hyperdivergent growth pattern or Bolton’s tooth size discrepancy. The aim of this investigation was to find the rational factor for overjet in Class II Division 1 malocclusion as growth pattern or Bolton's discrepancy in these subjects. Methods: 120 untreated Class II Division 1 cases who re...

OBJECTIVE To compare the effect of 800 vs 400 IU of daily oral vitamin D3 on the prevalence of vitamin D deficiency (VDD) at 40 weeks' postmenstrual age (PMA) in preterm infants of 28 to 34 weeks' gestation. METHODS In this randomized double-blind trial, we allocated eligible infants to receive either 800 or 400 IU of vitamin D3 per day (n = 48 in both groups). Primary outcome was VDD (serum ...

PURPOSE This study was performed to investigate the relationship between serum vitamin D and parathyroid hormone (PTH) levels as well as to describe the prevalence and the risk factors of vitamin D deficiency (VDD) in Korean children. METHODS Participants were 1,212 children aged 4 to 15 years, who visited Bundang CHA Medical Center (located at 37°N) between March 2012 and February 2013. Over...

Fertilization in flowering plants requires a complex series of coordinated events involving interaction between the male and female gametophyte. We report here molecular data on one of the key events underpinning this process - the death of the receptive synergid cell and the coincident bursting of the pollen tube inside the ovule to release the sperm. We show that two REM transcription factors...

Increased leakage current and device variability are the major challenges with CMOS technology scaling. Since Static Random Accessed Memory (SRAM) is often the largest component in the embedded digital systems or System-on-Chip (SoC), it is more vulnerable to those challenges. To effectively reduce SRAM leakage and/or active power, supply voltage (VDD) is often scaled down during standby and/or...
