0305-7364/0 * For corre bcgn.grignon. There is still disagreement about whether crop growth rate or soil nitrate concentration control nitrogen absorption by crops under ®eld conditions. The in ̄uence of these factors on the control of N uptake rate was examined in the absence of water stress, using data on dry matter production, above-ground nitrogen accumulation and soil nitrate concentration ...

BACKGROUND Cardiac resynchronization therapy (CRT) delivered via left ventricular (LV) endocardial pacing (ENDO-CRT) is associated with improved acute hemodynamic response compared with LV epicardial pacing (EPI-CRT). The role of cardiac anatomy and physiology in this improved response remains controversial. We used computational electrophysiological models to quantify the role of cardiac geome...

AIMS To examine A, C, Y, and W135 Neisseria meningitidis serogroup characterisation by ultrasonic standing wave enhanced latex agglutination tests (USELATs) of clinical samples. In addition, to determine USELAT enhancement of detection sensitivity for the individual antigens compared with conventional card latex agglutination tests (LATs). METHODS Wellcogen (Abbott Murex), Slidex meningite ki...

Nephronophthisis (NPH) is a genetically heterogenous kidney disease and represents the most common genetic cause for end-stage renal disease in children. It is caused by the mutation of genes encoding for the nephrocystin proteins (NPHPs) which localize to primary cilia or centrosomes, classifying this disease as a 'ciliopathy'. Recently, it has been shown that NPHP4 acts as a potent negative r...

  Herpes simplex virus type 1 establishes a latent infection in the peripheral nervous system following primary infection. During latent infection, virus genome exhibit limited transcription, with the HSV LATs consistently detected in latency infected ganaglia. Following ocular infection viral latency develops in the trigeminal ganglia. In this study PCR has been used for detection of HSV-1 nuc...

In this study we used a herpes simplex virus type 1 (HSV-1) deletion mutant to identify a segment of the genome necessary for epinephrine-induced reactivation in the rabbit eye model of herpetic recurrent disease. In HSV-1 latently infected neural tissue, the only abundant viral products are the latency-associated transcripts (LATs). At least one promoter of LAT has been identified, and mutatio...

The Australian Community Psychologist Volume 20 No 1 June 2008 The number of separate kerbside dryrecycling and organic waste collection systems operated by UK Local Authorities (LAs) has risen sharply as a result of the implementation of the European Landfill Directive (99/31/EC) into UK legislation on the 16th July 2001, concerns over remaining available landfill void space, and statutory rec...

PURPOSE To examine cancer genes undergoing epigenetic inactivation in a set of T-cell acute lymphoblastic leukemias (T-ALLs) to obtain the CpG island methylator phenotype (CIMP) in the disease and its possible correlation with clinical features and outcome of the patients. PATIENTS AND METHODS Methylation-specific polymerase chain reaction was used to analyze methylation of the ADAMTS-1, ADAM...
