BACKGROUND Transcriptional feedback loops are central to circadian clock function. However, the role of neural activity and membrane events in molecular rhythms in the fruit fly Drosophila is unclear. To address this question, we expressed a temperature-sensitive, dominant negative allele of the fly homolog of dynamin called shibire(ts1) (shi(ts1)), an active component in membrane vesicle sciss...

In adults, calculation of left ventricular mass (LVM) has been shown to give higher values when based on M-mode measurements obtained by the second-harmonic imaging (SHI) technique than with the older fundamental imaging (FI) technique. No information is available in paediatric subjects. This study, therefore, compares LVM calculated from measurements obtained with SHI and FI in 14 children, ag...

Tacrolimus, an immunosuppressant with narrow therapeutic window, has been used widely in transplant patients. Grapefruit juice and pomelo have been reported to increase the blood levels of tacrolimus. Zhi Ke and Zhi Shi, the ripe peels and unripe fruits of Citrus aurantium which is chemotaxonomically related to grapefruit and pomelo, are in wide use in clinical Chinese medicine. To investigate ...

OBJECTIVE The Government of Swaziland decided to explore the feasibility of social health insurance (SHI) in order to enhance universal access to health services. We assess the financial feasibility of a possible SHI scheme in Swaziland. The SHI scenario presented is one that mobilises resources additional to the maintained Ministry of Health and Social Welfare (MOHSW) budget. It is designed to...

The yeast shi mutation affects the spacing between the TATA promoter element and transcription initiation sites; for the H2B and ADH1 genes, a series of start sites located approximately 50-80 bp downstream of TATA is used in addition to the wild-type initiation sites located at around 100 bp from TATA (1). Here, the yeast SHI wild-type gene has been isolated by complementation and shown to be ...

BACKGROUND Deliberate Self-Harm (DSH) is the intentional destruction of healthy body tissue without suicidal intent. DSH behaviours in non-clinical populations vary, and instruments containing a range of behaviours may be more informative than ones with restricted content. The Self-Harm Inventory (SHI) is a widely used measure of DSH in clinical populations (mental and physical health) and cove...

Diffusion tensor imaging (DTI) using variable diffusion times (t(diff)) was performed to investigate wild-type (wt) mice, myelin-deficient shiverer (shi) mutant mice and shi mice transplanted with wt neural precursor cells that differentiate and function as oligodendrocytes. At t(diff) = 30 ms, the diffusion anisotropy "volume ratio" (VR), diffusion perpendicular to the fibers (lambda( perpendi...
