Group-based behaviour therapy improves self-care, glycaemic control and distress in adults with type 1 diabetes.

Aims: Psychological interventions have had modest effects on HbA1c in adults with Type 1 diabetes (T1D). We evaluated a novel behaviour therapy (BT) group program aiming to improve diabetes self-care and reduce HbA1c and distress. Core features were the application of a functional-analytic model, behavioural self-management training, and personally selected T1D self-care behaviours as treatment targets.

At-line porosity sensing for non-destructive disintegration testing in immediate release tablets.

Fully automated at-line terahertz time-domain spectroscopy in transmission mode is used to measure tablet porosity for thousands of immediate release tablets. The measurements are rapid and non-destructive. Both laboratory prepared tablets and commercial samples are studied.

Selective Sampling Importance Resampling Particle Filter Tracking With Multibag Subspace Restoration.

The focus of this paper is a novel object tracking algorithm which combines an incrementally updated subspace-based appearance model, reconstruction error likelihood function and a two stage selective sampling importance resampling particle filter with motion estimation through autoregressive filtering techniques. The primary contribution of this paper is the use of multiple bags of subspaces with which we aim to tackle the issue of appearance model update. The use of a multibag approach allows our algorithm to revert to a previously successful appearance model in the event that the primary model fails.

Associations of demographic and behavioural factors with glycaemic control in young adults with type 1 diabetes mellitus.

Background: Despite recognised benefits of optimal glycaemic control in patients with type 1 diabetes mellitus (T1DM), good control is still difficult to achieve, particularly for adolescents and young adults. Recognition of factors that may assist early optimisation of glycaemic control is therefore important.

Aims: We explored associations of demographic, social and behavioural factors with glycosylated haemoglobin (HbA1c) levels in participants with T1DM aged 18-25 years.

Interactions and binding energies of dimethyl methylphosphonate and dimethyl chlorophosphate with amorphous silica.

The fundamental interactions of dimethyl methylphosphonate (DMMP) and dimethyl chlorophosphate (DMCP) on amorphous silica nanoparticles have been investigated with transmission infrared spectroscopy and temperature-programmed desorption (TPD). DMMP and DMCP both adsorb molecularly to silica through the formation of hydrogen bonds between isolated silanols and the phosphoryl oxygen of the adsorbate. The magnitude of the shift of the ν(OH) mode upon simulant adsorption is correlated to the adsorption strength.

The mathematical origins of the kinetic compensation effect: 2. The effect of systematic errors.

The kinetic compensation effect states that there is a linear relationship between Arrhenius parameters ln A and E for a family of related processes. It is a widely observed phenomenon in many areas of science, notably heterogeneous catalysis. This paper explores mathematical, rather than physicochemical, explanations for the compensation effect in certain situations.

The mathematical origins of the kinetic compensation effect: 1. The effect of random experimental errors.

The kinetic compensation effect states that there is a linear relationship between Arrhenius parameters ln A and E for a family of related processes. It is a widely observed phenomenon in many areas of science, notably heterogeneous catalysis. This paper explores one of the mathematical, rather than physicochemical, explanations for the compensation effect and for the isokinetic relationship.

Analysis of temperature programmed desorption (TPD) data for the characterisation of catalysts containing a distribution of adsorption sites.

This paper discusses some methods of analysing TPD data for samples obeying first-order desorption kinetics and proposes several improvements to existing practice. The methods apply in the case when the Arrhenius parameters A and E for each site are independent of coverage, and thus are normally suitable for the characterisation of porous solids. An improved implementation of the condensation approximation method is proposed to gain an initial estimate of the adsorption site distribution.

A mobile screening programme for the cardiovascular and microvascular complications of Type 2 diabetes in primary care.

The Diabetes National Service framework (NSF), and the quality payments in the new contract for UK General Practitioners, promote regular screening for diabetes complications. The new contract also includes immediate incentives to meet screening and quality targets, but it will be difficult to meet these targets in primary care. We have developed a mobile 'annual review' programme for patients with Type 2 diabetes managed solely in primary care, that screens for cardiovascular disease, hypertension, retinopathy and neuropathy at the patient's general practice, and gives written foot care, dietary advice and level 1 smoking cessation advice to all patients.

A fourier transform infrared spectroscopic and solid-state NMR study of bone mineral in osteogenesis imperfecta.

Fourier transform infrared spectroscopy and 31P solid-state nuclear magnetic resonance spectroscopy were used to determine if any structural or compositional differences in osteogenesis imperfecta (OI) bone mineral could be detected that might help to explain the bone fragility observed in this disease. A previous study by Cassella et al. used an electron probe X-ray microanalytical technique to compare the calcium to phosphorus (Ca/P) molar ratios in normal bone and bone from patients with OI.

Practice Management Guidelines for Prophylactic Antibiotic Use in Tube Thoracostomy for Traumatic Hemopneumothorax: the EAST Practice Management Guidelines Work Group. Eastern Association for Trauma.

Multiple factors contribute to the development of posttraumatic empyema. These factors include the conditions under which the tube is inserted (emergent or urgent), the mechanism of injury, retained hemothorax, and ventilator care. The incidence of empyema in placebo groups ranges between 0 and 18%.

Complexes of Zn(2+), Cd(2+), and Hg(2+) with 2-(alpha-Hydroxybenzyl)thiamine Monophosphate Chloride.

The binding sites of Zn(2+), Cd(2+), and Hg(2+) in complexes with 2-(alpha-hydroxybenzyl)thiamine monophosphate chloride, (LH)(+)Cl(-), have been investigated in the solid state [2-(alpha-hydroxybenzyl)thiamin monophosphate chloride monoprotonated at the phosphate group and protonated at N(1)' is denoted as (LH)(+)Cl(-); therefore, the ligand monoprotonated at the phosphate group and deprotonated at N(1)' is L]. Complexes of formulae MLCl(2), M(LH)Cl(3), and (MCl(4))(2)(-)(LH)(2)(+) (M = Zn(2+), Cd(2+), and Hg(2+)) were isolated in aqueous and methanolic solutions, depending on pH. The crystal structure of the complex of formula HgL(2)Cl(2) was solved, together with that of the free ligand (LH)(+)Cl(-), by X-ray crystallography.

Solid State Dynamics of Tricarbonyl(eta-1,5-cyclohexadienylium)iron Tetrafluoroborate and Tricarbonyl(eta-1,5-cycloheptadienylium)iron Tetrafluoroborate.

The dynamic behavior of [(C(6)H(7))Fe(CO)(3)]BF(4) (I) and [(C(7)H(9))Fe(CO)(3)]BF(4) (II) in the solid state has been investigated principally by NMR spectroscopy. High-resolution variable-temperature (1)H and (13)C NMR spectra indicate that both complexes have a solid state phase transition above which there is rapid reorientation of the cyclodienylium rings and fast exchange of the carbonyl groups. The transition occurs between 253 and 263 K for I and between 329 and 341 K for II.

13C CP/MAS NMR Studies of Hemoprotein Models with and without an Axial Hindered Base: (13)C Shielding Tensors and Comparison with Hemoproteins and X-ray Structural Data.

13C cross-polarization magic-angle-spinning (CP/MAS) NMR spectra of several carbonmonoxide (93-99% (13)C enriched) hemoprotein models with 1,2-dimethylimidazole (1,2-diMeIm) and 1-methylimidazole (1-MeIm) as axial ligands are reported. This enables the (13)CO spinning sideband manifold to be measured and hence the principal components of the (13)CO chemical shift tensor to be obtained. Negative polar interactions in the binding pocket of the cap porphyrin model and inhibition of Fe-->CO back-donation result in a reduction in shielding anisotropy; on the contrary, positive distal polar interactions result in an increase in the shielding anisotropy and asymmetry parameter in some models.

31P solid-state NMR measurements used to detect interactions between NADPH and water and to determine the ionisation state of NADPH in a protein-ligand complex subjected to low-level hydration.

31P-NMR spectra of NADPH and NADPH bound to Lactobacillus casei dihydrofolate reductase have been recorded using the techniques of cross-polarization, magic-angle spinning and high-power proton-decoupling on both lyophilized and hydrated samples. Previous studies on the lyophilized complex of L. casei dihydrofolate reductase with NADPH and methotrexate, measuring the isotropic shifts and principal components of the chemical shift tensors, have shown that the 2'-phosphate group of bound NADPH exists as a mixture of the dianionic and monoanionic states [Gerothanassis, I.

Benign symmetric lipomatosis.

We report a case of massive, benign symmetric lipomatosis associated with laryngeal compression. Current views on the aetiology and management of this rare disease are discussed.

31P-NMR studies of NADPH, NADP+ and the complex of NADPH and methotrexate with Lactobacillus casei dihydrofolate reductase in the solid state.

31P-NMR spectra on solid samples of NADP+, NADPH and NADPH bound to Lactobacillus casei dihydrofolate reductase have been recorded using the techniques of cross polarisation, magic angle spinning and high power proton decoupling. The isotropic chemical shifts, the principal components of the shielding tensors and the asymmetry parameters for the 31P nuclei in the 2'-phosphate and pyrophosphate groups have been measured. The isotropic shifts show similar trends to the chemical shifts measured in solution.

Solid-state 27Al NMR studies of aluminophosphate molecular sieves. Enhanced resolution by quadrupole nutation and double-rotation.

Solid-state 27Al NMR spectra of several aluminophosphate molecular sieves have been recorded with conventional magic-angle spinning (MAS), double-rotation (DOR) and quadrupole nutation with fast MAS. Enhanced resolution was obtained in the quadrupole nutation experiment at certain radiofrequency pulse strengths. This extra resolution can be comparable to that attainable using DOR, and does not introduce spinning sidebands.

"Swiss roll" laryngotracheoplasty in young children.

Five children with acquired subglottic stenosis were successfully decannulated utilizing a modification of the Evans and Todd "Swiss roll" technique. Modifications including laryngofissure from within the lumen, midline tracheocricoid incision, and posterior cricoid cartilage split seem to be beneficial. There are still problems with postoperative granulations.

The primate psi beta 1 gene. An ancient beta-globin pseudogene.

The human beta-globin gene cluster contains five functional genes plus a single pseudogene termed psi beta 1. Hybridization and comparative sequence analysis show that this pseudogene is not the product of a recent gene duplication, but is ancient and has been maintained in all major primate groups ranging from prosimians to anthropoids, at the same position as in man, between gamma- and delta-globin genes. In the lemur, a prosimian, the central exons of the psi beta 1 and delta-globin genes have undergone an unequal exchange, which has resulted in a contraction of the beta-globin gene cluster and the formation of a Lepore-type psi beta 1-delta globin pseudogene.

A comparison of vertebrate interferon gene families detected by hybridization with human interferon DNA.

Cloned human interferon complementary DNAs were used as hybridization probes to detect interferon alpha and beta gene families in restriction endonuclease digests of total genomic DNA isolated from a wide range of vertebrates and invertebrates. A complex interferon-alpha multigene family was detected in all mammals examined, whereas there was little or no cross-hybridization of human interferon-alpha complementary DNA to non-mammalian vertebrates or invertebrates. In contrast, human interferon-beta complementary DNA detected one or two interferon-beta genes in all mammals tested, with the exception of the cow and the blackbuck, both of which possessed a complex interferon-beta multigene family which has presumably arisen by a recent series of gene duplications.
