Enzymatic Degradation of Model Cellulose Film Pre-Treated with Antimicrobial Agent

Enzymatic degradation of model cellulose films pre-treated with antimicrobial agent, 3-(trimethoxysilyl)-propyldimethyloctadecyl ammonium chloride (TMPAC) was investigated. AFM topographical imaging was used to assess the surface morphology, roughness, and thickness of the dried and hydrated model cellulose film. The kinetics of the model cellulose film in the hydrated state, the adsorption of TMP

Magnitude and trends of inequalities in antenatal care and delivery under skilled care among different socio-demographic groups in Ghana from 1988-2008

Background: Improving maternal and reproductive health still remains a major challenge in most low-income countries especially in sub-Saharan Africa. The growing inequality in access to maternal health interventions is an issue of great concern. In Ghana, inadequate attention has been given to the inequality gap that exists amongst women when accessing antenatal care during pregnancy and skilled a

PKC alpha expression is a marker for breast cancer aggressiveness

Background: Protein kinase C (PKC) isoforms are potential targets for breast cancer therapy. This study was designed to evaluate which PKC isoforms might be optimal targets for different breast cancer subtypes. Results: In two cohorts of primary breast cancers, PKC alpha levels correlated to estrogen and progesterone receptor negativity, tumor grade, and proliferative activity, whereas PKC delta a

Drug dissolution rate measurements - evaluation of the rotating disc method.

Dissolution rate measurements are important to understand the behaviour of drugs or drug formulations. Many methods for measuring dissolution rates are available and a good choice should be based on method limitations as well as drug characteristics. In the present study the rotating disc method was critically evaluated for dissolution rate measurements, using aspirin and benzoic acid as model sub

Dyslexic Students: Success Factors for Support in a Learning Environment

This study examines possible success factors when developing technical solutions for dyslexic students. Findings in the literature, in a web survey answered by students and in the experiences from the development process at the Medical Faculty Library, Lund University, were used to find out potential success factors and difficulties. The literature found describes what dyslexia is, the situation f

The role of integrin glycosylation in galectin-8-mediated trabecular meshwork cell adhesion and spreading

Primary open angle glaucoma (POAG) is a major blindness-causing disease, characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork (TM) lining the aqueous outflow pathway modulates the aqueous outflow facility. TM cell adhesion, cell-matrix interactions, and factors that influence Rho signaling in TM cells are thought to play a pivotal

Determinants of stress fracture risk in United States Military Academy cadets

Background: Prior studies have identified some risk factors for stress fracture in athletes and military recruits. Objective: To determine whether historical factors, physical measures, biochemical variables of skeletal metabolism, genetic factors, bone density (BMD) and bone size could predict risk of stress fracture over 4 years in physically fit cadets at the US Military Academy (USMA). Methods

Multiple Andreev reflections in hybrid multiterminal junctions

We investigate theoretically charge transport in hybrid multiterminal junctions with superconducting leads kept at different voltages. It is found that multiple Andreev reflections involving several superconducting leads give rise to rich subharmonic gap structures in the current-voltage characteristics. The structures are evidenced numerically in junctions in the incoherent regime.

Evidence for Cardiomyocyte Renewal in Humans

It has been difficult to establish whether we are limited to the heart muscle cells we are born with or if cardiomyocytes are generated also later in life. We have taken advantage of the integration of carbon-14, generated by nuclear bomb tests during the Cold War, into DNA to establish the age of cardiomyocytes in humans. We report that cardiomyocytes renew, with a gradual decrease from 1% turnin

Wind power or uranium mine: Appraisal of two energy-related environmental changes in a local context

This study explores factors associated with the individual's appraisal of anticipated environmental changes caused by energy production facilities. The study took place in a Swedish village where exploratory drilling, that could eventually lead to a uranium mine, was being conducted at the same time as a wind farm was approved. Results from the survey, which included the total population, were int

Bacterial and fungal growth in soil heated at different temperatures to simulate a range of fire intensities

The intensity of a fire is an important factor determining the recovery of soil microorganisms after a forest fire, since it can alter the quality and quantity of carbon sources. Recovery of the microbial community was studied in a Mediterranean pine forest soil subjected to different temperatures to simulate the short-term effects of fire intensity on bacterial and fungal growth, estimated using

Molecular subtypes in ductal carcinoma in situ of the breast and their relation to prognosis: a population-based cohort study

Background: Different molecular subtypes of breast cancer have been identified based on gene expression profiling. Treatment suggestions based on an approximation of these subtypes by immunohistochemical criteria have been published by the St Gallen international expert consensus panel. Ductal carcinoma in situ (DCIS) can be classified into the same molecular subtypes. Our aim was to study the rel

A large-scale replication study identifies TNIP1, PRDM1, JAZF1, UHRF1BP1 and IL10 as risk loci for systemic lupus erythematosus

Genome-wide association studies have recently identified at least 15 susceptibility loci for systemic lupus erythematosus (SLE). To confirm additional risk loci, we selected SNPs from 2,466 regions that showed nominal evidence of association to SLE (P < 0.05) in a genome-wide study and genotyped them in an independent sample of 1,963 cases and 4,329 controls. This replication effort identified fiv

Utility Disturbance Management in the Process Industry

Use of utilities, such as steam and cooling water, is very common at industrial sites. Utilities are often shared between several production areas, and a disturbance in the supply of a utility is therefore likely to affect a large part of the production site, and cause great loss of revenue. In order to minimize the loss of revenue due to disturbances in utilities, the optimal supply of utilities

Lighting Control Systems for Energy Saving and User Acceptance: State-of-the-art and future directions

Popular Abstract in Swedish Belysning står för en femtedel av den globala elanvändningen. I Sverige motsvarar efterfrågan på energi för belysning i kontorsbyggnader 20% av den totala elanvändningen. Utbyte av gamla belysningsanläggningar anses vara bland de mest kostnadseffektiva sätten att minska energianvändningen i byggnader. I synnerhet utlovar användningen av avancerade ljusstyrningssystem enLighting accounts for one-fifth of global electricity use. In Sweden, energy demand for lighting corresponds to 20% of the total electricity use in office buildings. Lighting retrofit measures are considered to be among the most cost-efficient way to reduce energy use in buildings. In particular, the use of advanced lighting control systems promises energy savings of between 2 and 60%, but system
