Our explorations of glycosyltransferase ElmGT from Streptomyces olivaceus Tü 2353, which shows an interesting flexibility regarding its sugar donor substrate, were extended toward various previously unexplored sugar co-substrates. The studies revealed that ElmGT, which normally transfers L-rhamnose to 8-demethyltetracenomycin C as a crucial biosynthetic(More)
A plasmid (pLN2) was generated in which genes involved in the biosynthesis of L-oleandrose in the oleandomycin producer Streptomyces antibioticus ATCC11891 were cloned. pLN2 was used to direct the biosynthesis of different deoxysugars by exchanging and/or adding genes from other antibiotic biosynthetic clusters. Transfer of the synthesized deoxysugars to(More)
BACKGROUND Vitamin A deficiency (VAD) has been closely related to acute respiratory infections (ARI), although information is still incomplete; for example, the frequency of VAD in children <5 years of age with pneumonia is not known, and the conditions associated with VAD have not been identified. This study was conducted to gain insight into the status of(More)
Recent studies considered that an increase in sympathetic activity (SA) may be responsible for left ventricular hypertrophy (LVH). Before and after renal transplantation (RT), we evaluated changes on left ventricular mass (LVM) and SA in 40 end-stage renal disease patients between 8 and 35 years old. Hypertension (95.0% vs. 71.0%; p=0.005), use of combined(More)
The purpose of this study was to demonstrate the usefulness of two-dimensional and Doppler echocardiography for diagnosing double mitral valve orifices (DMVO) in addition to identifying associated pathologies. We report five cases, three male and two female with an age ranging from 4 to 44 years old (mean age: 17 years), with the diagnosis of DMVO according(More)
BACKGROUND Pathogenesis of left ventricular hypertrophy (LVH) is multifactorial, but evidence that the sympathetic system is involved in progression of cardiovascular structural alterations in hypertension is substantial. However, the relationship between heart sympathetic activity and left ventricular mass in normotensive obese subjects has not been(More)
BACKGROUND AND OBJECTIVE Elevated serum low-density lipoprotein cholesterol (LDL-C) is a major cardiovascular risk factor. This study aimed to determine the efficacy and safety of co-administration of the cholesterol absorption inhibitor ezetimibe with an HMG-CoA reductase inhibitor (statin) in the treatment of Mexican patients with dyslipidaemia who had(More)
Magnetic Resonance Imaging (MRI) is a valuable complementary technique to prenatal ultrasound. It is useful in the detection and characterization of the fetal central nervous system (CNS) anomalies, partly due to the use of ultrafast sequences to reduce acquisition times. This is a revision article that shows representative cases by the authors. We include(More)
We present a new formulation to derive evaporative fraction (EF) and evapotranspiration (ET) maps from remotely sensed data without auxiliary relationships such as those relating a vegetation index and land surface temperature or site-specific relationships. The new equation is based on Grager and Gray's complementary relationship and Priestley-Taylor's(More)
