Transferrin and Lactoferrin – Human Iron Sources for Enterococci

To overcome limitations in iron acquisition, enterococci have evolved a number of mechanisms to scavenge iron from the host iron-binding proteins – transferrin (TR) and lactoferrin (LF). The aim of this study was to demonstrate the mechanisms by which enterococci utilize human TR and LF bound iron. The study included two strains of Enterococcus faecalis grown in iron-deficient and iron-excess media respectively. The binding activity of both proteins was monitored using proteins labelled

Hemochromatosis, iron, and blood donation: a short review

Hereditary hemochromatosis (HH), an autosomal recessive disease of iron overload, is one of the most common inherited diseases. The candidate gene (HFE) for HH has been identified recentIy and a DNA-based test for the mutation is available. Treatment for HH patients with elevated iron stores include repeated phlebotomy. Left untreated, iron overload can lead to cirrhosis, organ failure, and a shortened life expectancy. In the past and present, blood collected for therapeutic purposes from

selectivity, low operation time, and no secondary toxic compounds production. Hence, the process of biosorption is promising for the remediation of heavy metals from polluted water bodies (Zawierucha et al. 2016). Among trace elements, iron is required for most of the living organisms for the formation of hemoglobin. High iron levels (200–250 mg/kg body weight) in drinking water may cause many ill effects and can be lethal (Prashanth et al. 2015). The presence of a high level of iron in the food products

ESTIMATION OF ENERGY INTENSITY IN INDIAN IRON AND STEEL SECTOR: A PANEL DATA ANALYSIS

India is the world’s third largest consumer of primary energy, which includes fossil fuels like coal, oil, etc. The total primary energy consumption in India in 2015 was 107 Mtoe. India’s total final energy consumption was estimated at 527 Mtoe of which the industrial sectors consumed about 30% (185 Mtoe) in 2013. The Iron and Steel sector is one of the most energy-intensive industries, consuming about 25% of the total industrial energy consumption. The energy consumption in Indian

ANALYSIS OF CONCRETE CORROSION OF MANHOLE LOCATED NEAR SOURCE OF ODOROUS EMISSION

Abstract The problem of corrosion of sanitary sewer concrete concerns the elements located just behind the expansion well. Evolving odorogenic substances and bioaerosols spread in the sewage system, cause in adverse conditions both chemical and biological corrosion of concrete. The paper presents the results of tests of samples taken from the top concrete circle and from a corroded cast iron hatch of 7 years old manhole located below the expansion well. Well elements were subjected to a strong

Published data also indicate the role of iron in inducing oxidative stress, due to its characteristic oxidation reduction properties and participation in the production of reactive oxygen species (Ke et al., 2003). Hepcidin is a peptide

The primary objective of the iron ore transport is to meet the daily loading and unloading schedules and minimize queues by maximizing the operations at the loading and unloading points. The VMR simulator developed uses macro-mesoscopic approach with Monte Carlo simulation. To validate the simulator, we used actual data of the railway and compared with reality. We obtained a very good adhesion to the value of 2.9% for

EDX results showed a linear relationship between Co% and Fe% up to a concentration of 500 ppm reflecting the possible ability of the isolate to synthesize intracellular siderophores storing iron and their release from the vacuoles. The participation of such siderophoresin conferring tolerance against cobalt is discussed

rails. One way to solve this problem is the use of alternative sand bulk materials [4]. As the latter, it is proposed to use abrasive materials having magnetic properties [15-18], for example, magnetite (FeFe2O4), which is the iron oxide of natural origin, and iron scale (FeOFe2O3), which is a by-product of foundry and forging. These materials are similar to quartz sand in terms of hardness. In this regard, the study of the use of magnetite and iron scale in order to increase the coefficient of

LiDAR derived terrain wetness indices to infer soil moisture above underground pipelines

Many major cities such as Sydney have extensive networks of water supply pipelines, including major trunk lines that are ageing and increasingly prone to failure. Many of these pipes are made of cast iron. This material is traditional and has been shown to have excellent long-term durability, with many pipes surviving well past 100 years. Others, however, fail much earlier, and often this is through corrosion of the external surfaces of pipes. Such corrosion usually leads to weakening of pipe

The main objective of the study was to demonstrate the possibility of replacing the materials of domestic and foreign production currently used for chain drums with alternative materials. ADIs were selected as materials that may replace the cast steels used so far. L35GSM cast steel, commonly used for mining chain wheels and austempered ductile iron, conforming with the requirements of EN-GJS-1400-1 quality grade were subjected to wear tests. On the basis of the experimental studies it has been

DESIGN OF AUTO-FOCUSING MODULES IN CELL PHONE CAMERAS

Endowed with Hall-effect sensors and voice coil motors, cell phone cameras as intelligent systems are capable to execute auto-focusing for acquiring sharp image. For the use of cell phone cameras, this study presents an innovative auto-focusing module. When coils are powered, induced magnetic fields generate N and S poles around iron cores in the actuator. Unlike voice coil motors that employ Lorentz force, the motion of the moving part in this study is arisen from a magnetic pole property

CHEMICAL REDUCTION OF NITRATES IN THE WASTEWATER FROM 2-EHN PRODUCTION

The objective of the research was to determine the efficiency of nitrate removal from wastewater from 2-ethylhexyl nitrate production using chemical reduction process. The average concentration of nitrate nitrogen in raw wastewater was about 5.2 g/dm3. The processes of chemical reduction were conducted both in batch and continuous flow reactor under strongly acid conditions using two reducers: steel swarf, as a source of iron, and technical grade urea. In the batch process the maximum degree of

There was an increase in the content of iron and manganese compounds, ammonium ions, as well as the presence of bacteriological contaminants in test water samples. For these reasons, problems with providing the receivers with water of appropriate quality parameters have been reported in described rural intakes.

BACTERIAL METALLOTHIONEINS

Heavy metals are found in all living organisms where, as indispensable microelements (e.g. zinc, iron, copper), are involved in endless metabolic processes. However, living organisms are also at a risk of exposure to highly toxic metals, including cadmium or lead, which do not play any physiological role. Among multiple mechanisms associated with the maintenance of micronutrient homeostasis and detoxification of unwanted metals, there is a family of low-molecular-weight, cysteine-rich proteins

Cost-effectiveness of FDA variance for blood collection from individuals with hereditary hemochromatosis at a 398-bed hospitalbased donor center

Hereditary hemochromatosis (HH) is treated by therapeutic phlebotomy to reduce excess body iron. This 398-bed, hospital-based donor center wanted to determine whether there was a financial advantage to requesting FDA approval to allow transfusion of blood components from eligible individuals with HH. Donor center records from 2008 were reviewed to identify all therapeutic phlebotomy patients with a diagnosis of HH. HH patients were contacted and asked to complete the AABB Uniform Donor History

Unlike RelA, this protein also demonstrates the activity of hydrolysing stringent response alarmones in a situation when environmental conditions improve [47, 53, 144].
