OBJECTIVE To compare the performance of patients with mild dementia (Mini Mental State Examination (MMSE) >23), depression (Montgomery-Asberg depression rating scale (MADRS) >12) and controls on tests of frontal executive function (FEF), to see if simple tools could be an adjunct to early recognition of dementia in primary care. DESIGN Subjects were(More)
The regulated turnover of endoplasmic reticulum (ER)-resident membrane proteins requires their extraction from the membrane lipid bilayer and subsequent proteasome-mediated degradation. Cleavage within the transmembrane domain provides an attractive mechanism to facilitate protein dislocation but has never been shown for endogenous substrates. To determine(More)
Prion diseases are associated with the conversion of cellular prion protein (PrP(C)) to toxic β-sheet isoforms (PrP(Sc)), which are reported to inhibit the ubiquitin-proteasome system (UPS). Accordingly, UPS substrates accumulate in prion-infected mouse brains, suggesting impairment of the 26S proteasome. A direct interaction between its 20S core particle(More)
The ability of ubiquitin to form up to eight different polyubiquitin chain linkages generates complexity within the ubiquitin proteasome system, and accounts for the diverse roles of ubiquitination within the cell. Understanding how each type of ubiquitin linkage is correctly interpreted by ubiquitin binding proteins provides important insights into the(More)
The asparagine hydroxylase, factor inhibiting HIF (FIH), confers oxygen-dependence upon the hypoxia-inducible factor (HIF), a master regulator of the cellular adaptive response to hypoxia. Studies investigating whether asparagine hydroxylation is a general regulatory oxygen-dependent modification have identified multiple non-HIF targets for FIH. However,(More)
AIM The aim was to determine the morbidity or mortality associated with the blind awake intubation technique in temporomandibular ankylosis patients. SETTINGS AND DESIGN A total of 48 cases with radiographically and clinically confirmed cases of temporomandibular joint (TMJ) ankylosis were included in the study for evaluation of anesthetic management and(More)
Nasopalatine duct cyst is the nonodontogenic developmental cyst, frequently occurring in the midline of the anterior maxillary region. The clinical presentation of the cyst is often varied and presents a diagnostic difficulty and frequently misdiagnosed as developmental or inflammatory odontogenic cystic lesion. This paper represents a large infected(More)
