Stearoyl-coenzyme A desaturase (SCD) is a key regulator of membrane fluidity, turns over rapidly, and represents a prototype for selective degradation of resident proteins of the endoplasmic reticulum. Using detergent-solubilized, desaturase-induced rat liver microsomes we have characterized a protease that degrades SCD. Degradation of SCD in vitro is highly selective, has a half-life of 3-4 h,...

background: with the increasing concern for health and nutrition, dietary fat has attracted considerable attention. the composition of fatty acids in the diet is important because they are associated with major diseases including cancers, diabetes, and cardiovascular disease. the fatty acid synthase (fasn) and stearoyl-coa desaturase (delta-9-desaturase) (scd) genes affect fatty acid compositio...

Among the many families of nonperiodic tilings known so far, SCD tilings are still a bit mysterious. Here, we determine the diffraction spectra of point sets derived from SCD tilings and show that they have no absolutely continuous part, that they have a uniformly discrete pure point part on the axis Re3, and that they are otherwise supported on a set of concentric cylinder surfaces around this...

BACKGROUND AND OBJECTIVES Data collected by the US Renal Data System (USRDS) identify sudden cardiac death (SCD) as the leading cause of death among hemodialysis patients. However, evidence suggests that clinical events captured on the USRDS death notification form may be inaccurate. A new method for classifying SCD was recently developed to enhance the accuracy of SCD classification. This stud...

BACKGROUND Children with sickle cell disease (SCD) may present oral conditions that can compromise children's health even more. However, there is still no consensus on the association between SCD and dental caries. The aim of this study was to assess caries prevalence in children with sickle cell disease (SCD), and the association of dental caries with socioeconomic factors, disease severity, a...

Sickle cell disease (SCD) results in neuropsychological complications that place adolescents at higher risk for limited educational achievement. A first step to developing effective educational interventions is to understand the impact of SCD on school performance. The current study assessed perceptions of school performance, SCD interference and acceptability of educational support strategies ...

INTRODUCTION Growth retardation and under-nutrition are common in children with sickle cell disease (SCD). The aim of this study was to compare the head circumference (HC) of SCD children and non-SCD children and to determine the effect of malnutrition on head circumference of children with SCD. METHODS This was a prospective case-control study conducted at the Lagos State University Teaching...

Many African Americans with sickle cell disease (SCD) also experience significant economic hardship. Yet, few studies of the psychosocial effects of SCD employ designs robust enough to control socioeconomic factors. This study compares the functioning of families with SCD to that of healthy controls matched for race and socioeconomic status. In general, functioning within SCD and control famili...

OBJECTIVE Epilepsy is associated with increased risk for sudden cardiac death (SCD). We aimed to establish, in a community based study, whether this association is mediated by epilepsy per se, use of antiepileptic medications (AEMs), or both. METHODS We studied SCD cases and age/sex matched controls in a case-control study in a large scale general practitioners' research database (n=478 661 p...
