To correlate dynein heavy chain (Dhc) genes with flagellar mutations and gain insight into the function of specific dynein isoforms, we placed eight members of the Dhc gene family on the genetic map of Chlamydomonas. Using a PCR-based strategy, we cloned 11 Dhc genes from Chlamydomonas. Comparisons with other Dhc genes indicate that two clones correspond to genes encoding the alpha and beta hea...
BACKGROUND Determine HIV Combo (DHC) is the first point of care assay designed to increase sensitivity in early infection by detecting both HIV antibody and antigen. We conducted a large multi-centre evaluation of DHC performance in Sydney sexual health clinics. METHODS We compared DHC performance (overall, by test component and in early infection) with conventional laboratory HIV serology (f...
UNLABELLED The purpose of the study was to compare the diagnostic accuracy of fluorodeoxyglucose (FDG) images obtained with a dual-head coincidence gamma camera (DHC) with those obtained with a dedicated PET in a series of 26 patients. METHODS Nineteen patients with known or suspected malignancies and 7 patients with neurological disorders underwent PET imaging after injection of approximatel...
BACKGROUND The physiotherapy dynamic humeral centring (DHC) aims to prevent subacromial impingement of rotator cuff tendons during elevation of the arm. The objective of the study was to determine whether DHC acts via an effect on subacromial impingement mechanism by assessing its effect on painful elevation of the arm in subacromial impingement syndrome. METHODS This is a secondary analysis ...
Results The resulta showed that 3,4-DHC with dose of 25mg/kg induced significant antinociception and anti-inflammation compared with control group. In additon the effect of DHC was higher in the chronic phase of formalin test, therefore it seems that DHC has better anti-inflammatory effect rather than analgesic effect. The dose of 25 mg/kg of DHC induces significant analgesia in hot plate test ...
BACKGROUND AND PURPOSE Dual-head coincidence gamma camera (DHC) imaging has been proposed as an alternative to dedicated ring-detector positron emission tomography (dr-PET) for clinical fluorodeoxyglucose (FDG) studies. The purpose of this investigation was to assess the quality of DHC images in FDG studies of the human brain. METHODS Seven healthy volunteers and 12 patients with various cere...
Effective DNA repair enables cancer cells to survive DNA damage induced by chemotherapeutic or radiotherapeutic treatments. Therefore, inhibiting DNA repair pathways is a promising therapeutic strategy for increasing the efficacy of such treatments. In this study, we found that dihydrocoumarin (DHC), a flavoring agent, causes deficiencies in double-stand break (DSB) repair and prolonged DNA dam...
Smith-Lemli-Opitz syndrome (SLOS) is a metabolic and developmental disorder caused by mutations in the gene encoding the enzyme 7-dehydrocholesterol reductase (Dhcr7). This reductase catalyzes the last step in cholesterol biosynthesis, and levels of 7-dehydrocholesterol (7-DHC), the substrate for this enzyme, are elevated in SLOS patients as a result of this defect. Our group has previously sho...
Faced with inherent inefficiencies built into transfer of a patient from emergency department (ED) to an inpatient bed, we determined that the timely availability of an inpatient bed was essential to improving efficiency and flow. Lack of beds early in the day was a major cause for delays and backup in the ED, which in turn placed the ED at risk for overcrowding and diversion. Review of the dis...
The formation of lipid electrophile-protein adducts is associated with many disorders that involve perturbations of cellular redox status. The identities of adducted proteins and the effects of adduction on protein function are mostly unknown and an increased understanding of these factors may help to define the pathogenesis of various human disorders involving oxidative stress. 7-Dehydrocholes...
