Nanoscale imaging of electric pathways in epitaxial graphene nanoribbons

Graphene nanoribbons (GNRs) are considered as major building blocks in future carbon-based electronics. The electronic performance of graphene nanostructures is essentially influenced and determined by their edge termination and their supporting substrate. In particular, semi-conducting, as well as metallic GNRs, can be fabricated by choosing the proper template which is favorable for device archi

RF reliability of gate last InGaAs nMOSFETs with high-k dielectric

A complete reliability study of the high-frequency characteristics for nMOSFETs on InGaAs channel with Al2O3/HfO2 gate dielectric is presented. DC gate voltage stress causes an increase in the transconductance frequency dispersion. Stress induced border traps degrade the maximum DC-transconductance, but do not react at high frequencies. The main degradation characteristics of the high-frequency me

Self-aligned gate-last surface channel In0.53Ga0.47As MOSFET with selectively regrown source and drain contact layers

III-V MOSFETs are currently being considered as a candidate for future high performance transistors [1]. In particular, In1-xGaxAs compounds are investigated for application in digital logic due to their advantageous electronic properties [2]. III-V technologies may be introduced beyond the 22 nm node, which will require a self aligned III/V device architecture as well as integration of high-¿ gat

Genome-wide mapping of bivalent histone modifications in hepatic stem/progenitor cells

The “bivalent domain,” a distinctive histone modification signature, is characterized by repressive trimethylation of histone H3 at lysine 27 (H3K27me3) and active trimethylation of histone H3 at lysine 4 (H3K4me3) marks. Maintenance and dynamic resolution of these histone marks play important roles in regulating differentiation processes in various stem cell systems. However, little is known reg

Alignment of endocrine, anthropometric and metabolic parameters in type 2 diabetes after intervention with an Okinawan-based Nordic diet

Background: An Okinawa-based Nordic diet with moderately low carbohydrate content and high fat and protein content has been shown to improve anthropometry and metabolism in type 2 diabetes.Objective: The objectives of this study were to measure plasma or serum levels of hormones regulating energy metabolism and metabolic control, that is, cholecystokinin (CCK), Cortisol, C-peptide, ghrelin, glucag

Intake of different types of red meat, poultry, and fish and incident colorectal cancer in women and men: results from the Malmö Diet and Cancer Study.

Background : Colorectal cancer (CRC) is considered one of the most common forms of cancer in the Western world. High intake of red and processed meat is considered to increase CRC development. Objective : This study examined associations between intake of red meats, poultry, and fish and incident CRC, and if weight status modifies the associations. Design : In the Malmö Diet and Cancer Study, diet

Longer colonic transit time is associated with laxative and drug use, Lifestyle factors and symptoms of constipation

Background Gastrointestinal symptoms and changes in colonic transit time (CTT) are common in the population. Purpose To evaluate consecutive patients who had been examined for CTT, along with completion of a diary about laxative and drug use, lifestyle factors, and gastrointestinal symptoms, to identify possible associations with longer or prolonged CTT. Material and Methods A total of 610 consecu

Calprotectin in serum and zonulin in serum and feces are elevated after introduction of a diet with lower carbohydrate content and higher fiber, fat and protein contents

Calprotectin is a marker of inflammation and zonulin is a marker of intestinal permeability. Diets with lower carbohydrate content and higher contents of fat, fiber and protein, e.g., Okinawan‑based diet, are considered to reduce inflammation and intestinal permeability. The aim of the present study was to evaluate calprotectin and zonulin levels in serum and feces after intervention with an Okina
