Objective: To assess the available data on the use of memantine-ChEI combination and to develop evidence-based recommendations.

Method: A systematic literature review with detailed discussion of the current evidence base.

Mesoporous silica-magnetite nanocomposite: fabrication and applications in magnetic bioseparations.

Magnetic bioseparations such as adsorption and elution of nucleic acids by a mesoporous superparamagnetic silica-magnetite nanocomposite are reported.

Childcare as a stabilizing influence on HPA axis functioning: a reevaluation of maternal occupational patterns and familial relations.

The influence of family relations, maternal occupational characteristics, and childcare1The UK terms "childcare," childcare centres' and "nurseries" are used throughout this paper to define group care for children prior to starting their first year of formal schooling at age 4 years and are used synonymously with the American terms "day-care" and "preschool." This form of group care is provided in a formal setting, outside the family home and excludes "childminding" (i.e.

Multicultural mental health services: projects for minority ethnic communities in England.

Black and minority ethnic (BME) communities form 7.8% of the total population of the U.K.

Water-soluble phosphines for direct labeling of peptides with technetium and rhenium: insights from electrospray mass spectrometry.

Direct labeling of salmon calcitonin (sCT) is possible in one step using water-soluble phosphines (sulfonated triphenylphosphines) as the reducing agent both for disulfide and for pertechnetate. Phosphines were the most efficient reducing agent for disulfide bonds among those examined. The phosphines both reduced the pertechnetate to Tc(III), and contributed to the technetium coordination sphere in the labeled product.

Loop 1 of transducer region in mammalian class I myosin, Myo1b, modulates actin affinity, ATPase activity, and nucleotide access.

Loop 1, a flexible surface loop in the myosin motor domain, comprises in part the transducer region that lies near the nucleotide-binding site and is proposed from structural studies to be responsible for the kinetic tuning of product release following ATP hydrolysis (1). Biochemical studies have shown that loop 1 affects the affinity of actin-myosin-II for ADP, motility and the V(max) of the actin-activated Mg2+-ATPase activity, possibly through P(i) release (2-8). To test the influence of loop 1 on the mammalian class I myosin, Myo1b, chimeric molecules in which (i) loop 1 of a truncated form of Myo1b, Myo1b1IQ, was replaced with either loop 1 from other myosins; (ii) loop 1 was replaced with glycine; or (iii) some amino acids in the loop were substituted with alanine and were expressed in baculovirus, and their interactions with actin and nucleotide were evaluated.

Long-term outcome for people with severe intellectual disabilities: impact of social impairment.

Results from a 25-year follow-up study of the Camberwell Cohort (L. Wing & Gould, 1978, 1979) were presented. Ninety-one people, ranging in age from 27 to 41 years, were traced, and an outcome measure was developed incorporating independent functioning, residential placement, employment, and quality of life.

Dyslexic students have more everyday cognitive lapses.

There is a dearth of information about the everyday performance difficulties of adult dyslexic people. This study investigates the empirical support for anecdotal reports of increased vulnerability to distraction in dyslexia, using the self-report Cognitive Failures Questionnaire (CFQ). Two groups of university students, a dyslexic group and a non-dyslexic control group, were asked to complete the CFQ.

What do lateralized displays tell us about visual word perception? A cautionary indication from the word-letter effect.

A common assumption underlying laterality research is that visual field asymmetries in lateralized word perception indicate the hemispheric specialisation of processes generally available for the perception of words, including words viewed in a more typical setting (i.e. in the central visual field).

Symptom control and patient adherence to treatment: key goals in the treatment of psychosis.

A CLINICIAN'S KEY GOALS WHEN TREATING PSYCHOSIS ARE TO control disease symptoms and to ensure patient adherence to treatment. Efficacy as well as side-effect profile are, therefore, the major selection criteria when choosing an antipsychotic medication.

What types of home are closing? The characteristics of homes which closed between 1996 and 2001.

Closures of care homes have received considerable public attention. Fee levels and the cost of upgrading homes to meet the national minimum standards have been identified as the main factors influencing closures. The present paper compares private residential homes, dual-registered homes and nursing homes for older people which have closed between 1996 and 2001 with homes which have remained open.

Green fluorescent protein as a tool to study epidermal growth factor receptor function.

The subcellular distribution of the epidermal growth factor receptor and its interaction with second messenger proteins has been explored using tagging with green fluorescent protein and its derivatives. EGFR itself has been fused with GFP and its natural life cycle and its internalisation in response to ligand determined. Several second messenger proteins including Shc and PI3kinase have also been tagged with fluorescent proteins and their subcellular redistribution in response to ligand activation has been filmed.

Tropomyosin exon 6b is troponin-specific and required for correct acto-myosin regulation.

The specificity of tropomyosin (Tm) exon 6b for interaction with and functioning of troponin (Tn) has been studied using recombinant fibroblast Tm isoforms 5a and 5b. These isoforms differ internally by exons 6a/6b and possess non-muscle exons 1b/9d at the termini, hence they lack the primary TnT(1)-tropomyosin interaction, allowing study of exon 6 exchange in isolation from this. Using kinetic techniques to measure regulation of myosin S1 binding to actin and fluorescently labeled Tm to directly measure Tn binding, we show that binding of Tn to both isoforms is similar (0.

Search for haplotype interactions that influence susceptibility to type 1 diabetes, through use of unphased genotype data.

Type 1 diabetes is a T-cell-mediated chronic disease characterized by the autoimmune destruction of pancreatic insulin-producing beta cells and complete insulin deficiency. It is the result of a complex interrelation of genetic and environmental factors, most of which have yet to be identified. Simultaneous identification of these genetic factors, through use of unphased genotype data, has received increasing attention in the past few years.

Probing nucleotide dissociation from myosin in vitro using microgram quantities of myosin.

The detailed kinetic analysis of novel myosin motors is often limited by the quantity of stable protein available for study. We show here that the use of coumarin based fluorescent ADP analogues allows the assay of ADP affinities and dissociation rate constants in a flash photolysis apparatus using microg quantities of the rabbit muscle myosin S1. We go on to use the analogues to characterise two other rat muscle myosin S1 and the motor domain of Dictyostelium cytoplasmic myosin II.

Characterization of a soil-derived bacterial consortium degrading 4-chloroaniline.

A bacterial consortium comprising four different species was isolated from an Indonesian agricultural soil using a mixture of aniline and 4-chloroaniline (4CA) as principal carbon sources. The four species were identified as Chryseobacterium indologenes SB1, Comamonas testosteroni SB2, Pseudomonas corrugata SB4 and Stenotrophomonas maltophilia SB5. Growth studies on aniline and 4CA as single and mixed substrates demonstrated that the bacteria preferred to grow on and utilize aniline rather than 4CA, although both compounds were eventually depleted from the culture supernatant.

Obesity as a cause of "false-positive" alcohol misuse laboratory investigations.

Three patients are reported with a prior history of alcohol misuse accompanied by abnormal liver toxicity tests and other indices of alcohol misuse. A decreased but persistently raised serum gamma-glutamyl transferase activity during subsequent abstinence or controlled drinking was interpreted incorrectly as due to continued alcohol misuse whereas obesity-related fatty liver was the probable cause. The value of serum carbohydrate deficient transferrin assays in the differential diagnosis of abnormal liver toxicity tests is emphasized.

The sexual health needs of people with learning disabilities.

The sexual health of people with learning disabilities raises important management and practice issues for health services, and should be examined in the context of the current policy emphasis on advocacy, person-centred services and social inclusion (Department of Health, 2001). People with learning disabilities may have limited access to mainstream health services, and sexual health and genitourinary medicine (GUM) services are no exception (DoH, 2001; 1998). They are often excluded from society, either because they are 'segregated' within specialist support services in the community or because they live in isolation with carers, and health and social care models do not always join up locally to meet their needs.

Fatty acids as haptens: exploring the limits of antigenicity.

Fatty acids (FAs) are relatively small, hydrophobic and highly mobile molecular structures with vital biological functions and a ubiquitous distribution. Surprisingly, however, they can be rendered immunogenic. We have synthesised a novel immunogen in which dicarboxylic linoleic acid was conjugated to a carrier protein.

Toward the use of a standardized assessment for young children with autism: current assessment practices in the UK.

Little is known about the progress of autistic children following specific interventions in England. Nor do we know how frequently standardized assessments are used to monitor progress or to evaluate specific educational interventions. The reports of 75 children with autism, for whom special educational provision had been determined by a local education authority, were reviewed.

Bayesian discrimination with longitudinal data.

The motivation for the methodological development is a double-blind clinical trial designed to estimate the effect of regular injection of growth hormone, with the purpose of identifying growth hormone abusers in sport. The data formed part of a multicentre investigation jointly sponsored by the European Union and the International Olympic Committee. The data are such that for each individual there is a matrix of marker variables by time point (nominally 8 markers at each of 7 time points).

Breeding chemists in Giessen.

The factors that contributed to Liebig's success in founding a research school at Giessen have been well known since the publication of Jack Morrell's seminal paper in 1972. Here the familiar Liebig-Giessen story is re-centred in a local geographical and historical context. Historical and political factors played a role in calling Liebig to Giessen and in ousting the existing chair holder, Zimmerman.

Ionic interactions play a role in the regulatory mechanism of scallop heavy meromyosin.

Heavy meromyosin from scallop (scHMM) striated muscle is regulated by calcium binding to the essential light chain. The regulation can be modeled with a calcium-dependent equilibrium between on and off scHMM conformations. The observed rate constant for mant-ADP dissociation from scHMM is calcium dependent, and we show here that it can be used to define the equilibrium constant (K(eq)) between on and off conformations.

c-erbB-4/HER4: friend or foe?

The c-erbB-4 receptor has ligand stimulated tyrosine kinase activity but reports differ as to whether it induces cell division or differentiation. There is also controversy regarding its role in breast cancer, with some reports associating overexpression with short survival and others with longer life.

Reducing misinformation effects in children with cognitive interviews: dissociating recollection and familiarity.

Two experiments examined the effect of a cognitive interview on 4- and 8-year-old children's correct recall and subsequent reporting of misinformation. Children viewed an event followed by misinformation that was read or self-generated either before or after a cognitive interview. Children were then given a recognition test under inclusion and exclusion instructions.
