Allotwinning in a molecular crystal: (1R,3S)-dimethyl 2-oxocyclohexane-1,3-dicarboxylate.

Two polytypic modifications of (1R,3S)-dimethyl 2-oxocyclohexane-1,3-dicarboxylate intergrow to form allotwins. One phase shows monoclinic symmetry, Cc, while the other is orthorhombic Pmc21. The structures may be considered as two different modes of superstructure ordering of an underlying, disordered structure. Considered in the same metrically orthorhombic unit cell a = 37.8883, b = 4.7233, c =

The Association Between APOE epsilon 4 and Alzheimer-type Dementia Among Memory Clinic Patients is Confined to those with a Higher Education. The DESCRIPA Study

We assessed the interaction between the APOE epsilon 4 allele and education level in the etiology of Alzheimer's disease (AD) among memory clinic patients from the multicenter DESCRIPA study. Subjects (n = 544) were followed for 1 to 5 years. We used Cox's stratified survival modeling, adjusted for age, gender, and center. APOE epsilon 4 predicted the onset of AD-type dementia in middle (HR 3.45 9

Incretin, insulinotropic and glucose-lowering effects of whey protein pre-load in type 2 diabetes: a randomised clinical trial

Aims/hypothesis Since protein ingestion is known to stimulate the secretion of glucagon-like peptide-1 (GLP-1), we hypothesised that enhancing GLP-1 secretion to harness its insulinotropic/beta cell-stimulating activity with whey protein pre-load may have beneficial glucose-lowering effects in type 2 diabetes. Methods In a randomised, open-label crossover clinical trial, we studied 15 individuals

A quantitative comparison of bird and bat wakes.

Qualitative comparison of bird and bat wakes has demonstrated significant differences in the structure of the far wake. Birds have been found to have a unified vortex wake of the two wings, while bats have a more complex wake with gradients in the circulation along the wingspan, and with each wing generating its own vortex structure. Here, we compare quantitative measures of the circulation in the

Glucose-lowering effect of the DPP-4 inhibitor sitagliptin after glucose and non-glucose macronutrient ingestion in non-diabetic subjects.

AIM: Recent studies suggest that the incretin concept is not restricted to glucose ingestion but relevant also after non-glucose macronutrient administration. We therefore hypothesized that raising incretin hormones reduces circulating glucose after both glucose and non-glucose macronutrient ingestion in healthy subjects. MATERIAL AND METHODS: Twelve healthy subjects received the dipeptidyl peptid

High-k oxides on InAs 100 and 111B surfaces

Al2O3 and HfO2 high-k oxides deposited by atomic layer deposition have been studied on InAs 100 and 111B surfaces. By using a low-frequency fitting routine, interface defect densities have been extracted. In general, both HfO2 and Al2O3 show similar D-it profiles, with a D-it minimum around 2x10(12) eV(-1)cm(-2).

Inhibition of HIV-1 disease progression by contemporaneous HIV-2 infection.

BACKGROUND: Progressive immune dysfunction and the acquired immunodeficiency syndrome (AIDS) develop in most persons with untreated infection with human immunodeficiency virus type 1 (HIV-1) but in only approximately 20 to 30% of persons infected with HIV type 2 (HIV-2); among persons infected with both types, the natural history of disease progression is poorly understood. METHODS: We analyzed d

Interleukin-6 drives melanoma cell motility through p38α-MAPK-dependent up-regulation of WNT5A expression.

Extensive research has demonstrated a tumor-promoting role of increased WNT5A expression in malignant melanoma. However, very little light has been shed upon how WNT5A expression is up-regulated in melanoma. A potential regulator of WNT5A expression is the pro-inflammatory cytokine Interleukin (IL)-6, which shares the ability of WNT5A to increase melanoma cell invasion. Here, we investigate whethe

Interface Controlled Oxidation States in Layered Cobalt Oxide Nanoislands on Gold

Layered cobalt oxides have been shown to be highly active catalysts for the oxygen evolution reaction (OER; half of the catalytic "water splitting" reaction), particularly when promoted with gold. However, the surface chemistry of cobalt oxides and in particular the nature of the synergistic effect of gold contact are only understood on a rudimentary level, which at present prevents further explor

Validity of the Stokes-Einstein Relation in Soft Colloids up to the Glass Transition

We investigate the dynamics of kinetically frozen block copolymer micelles of different softness across a wide range of particle concentrations, from the fluid to the onset of glassy behavior, through a combination of rheology, dynamic light scattering, and pulsed field gradient NMR spectroscopy. We additionally perform Brownian dynamics simulations based on an ultrasoft coarse- grained potential,

Diabetes Antibody Standardization Program: evaluation of assays for insulin autoantibodies

Aims/hypothesis Insulin autoantibodies (IAA) are important in type I diabetes risk assessment. However, their determination varies more between laboratories than other diabetes autoantibodies. The Diabetes Antibody Standardization Program (DASP) aims to improve and standardise measurement of autoantibodies associated with type I diabetes. We report the results of measurement of IAA from DASP works

Control of recompression HCCI with a three region switching controller

Homogeneous charge compression ignition (HCCI) presents new challenges in combustion phasing control due to the lack of direct ignition trigger. In addition, recompression HCCI possesses cycle-to-cycle coupling through trapping a large portion of the exhaust gas in the cylinder. This paper examines the change in the cycle-to-cycle coupling around different operating points in recompression HCCI an

Possible compensation of the QCD vacuum contribution to the dark energy

We suggest one of the possible ways to compensate the large negative quantum-topological QCD contribution to the vacuum energy density of the Universe by means of a positive constant contribution from a cosmological Yang-Mills field. An important role of the exact particular solution for the Yang-Mills field corresponding to the finite-time instantons is discussed. An interesting connection of the

Impact of ventilation/perfusion single-photon emission computed tomography on treatment duration of pulmonary embolism.

The aim of the study was to establish whether the duration of anticoagulant (AC) therapy can be tailored, on an objective basis, by using ventilation/perfusion single-photon emission computed tomography (V/P SPECT) and to assess the extent of residual perfusion defects over time. In particular, we addressed the following: (a) is the extent of perfusion recovery at 3 months of initial pulmonary emb

Home treatment of patients with small to medium sized acute pulmonary embolism.

Most patients with acute pulmonary embolism (PE) are still treated as inpatients. This is a retrospective cohort study of patients with acute PE, diagnosed using V/P SPECT between 2007 and 2011. Patients were treated at home if they were hemodynamically stable, did not require oxygen or parenteral analgetics, had no contraindications to anticoagulant treatment and V/P SPECT showed an extension of

Preservatives in cosmetics in the Israeli market conform well to the EU legislation

BackgroundPreservatives are important and frequent skin sensitizers, found in a wide range of products for personal and occupational use. According to the European legislation, some cosmetic ingredients are restricted in terms of quantity and a detailed list of ingredients must be present on the product or packaging. ObjectivesTo examine the use of preservatives in common cosmetics on the Israeli

How information availability interacts with visual attention during judgment and decision tasks

Decisions in front of a supermarket shelf probably involve a mix of visually available information and associated memories – and interactions between those two. Several cognitive processes, such as decision-making, search and various judgments, are therefore likely to co-occur, and each process will influence visual attention. We conducted two eye-tracking experiments capturing parts of these feat

Lactic acid bacterial symbionts in honeybees - an unknown key to honey's antimicrobial and therapeutic activities.

Could honeybees' most valuable contribution to mankind besides pollination services be alternative tools against infections? Today, due to the emerging antibiotic-resistant pathogens, we are facing a new era of searching for alternative tools against infections. Natural products such as honey have been applied against human's infections for millennia without sufficient scientific evidence. A uniqu

Soluble TNF receptors are associated with Abeta metabolism and conversion to dementia in subjects with mild cognitive impairment.

OBJECTIVE: There is evidence supporting that tumor necrosis factor receptor (TNFR)-signaling can induce production of beta-amyloid (Abeta) in the brain. Moreover, amyloid-induced toxicity has been shown to be dependent on TNFR-signaling. However, it is still unclear whether TNFRs are involved in the early stages of dementia. METHODS: We analyzed soluble TNFR1 and TNFR2 levels in plasma and cerebro
