Radiopharmaceuticals Adverse Events Management.

Background And Purpose: Radiopharmaceuticals are radioactive compounds used for diagnostic or therapeutic purposes which are most often administered intravenously. Adverse events that may induce both adverse reactions and drug-to-drug interactions with changes in expected biodistribution, potentially affecting patient safety and diagnostic accuracy. Adverse reactions are relatively rare due to the small doses and under-reporting is the norm.

EGFR Inhibition by Erlotinib Rescues Desmosome Ultrastructure and Keratin Anchorage and Protects against Pemphigus Vulgaris IgG-Induced Acantholysis in Human Epidermis.

Pemphigus is a severe blistering disease caused by autoantibodies primarily against the desmosomal cadherins desmoglein (DSG)1 and DSG3, which impair desmosome integrity. Especially for the acute phase, additional treatment options allowing to reduce corticosteroids would fulfill an unmet medical need. In this study, we provide evidence that EGFR inhibition by erlotinib ameliorates pemphigus vulgaris IgG-induced acantholysis in intact human epidermis.

Characterization and under Water Action Behaviour of a New Plaster-Based Lightened Composites for Precast.

Plaster is a construction material widely used for the production of prefabricated parts in building construction due to its high capacity for hygrothermal regulation, its good mechanical performance, and its fireproof nature, among other factors. Its historical use has been linked to ornamental elements, although more recent research is oriented towards the industrialisation of plaster composites and the design of prefabricated parts for false ceilings and interior partitions. In this work, the behaviour against water of four new plaster-based composite materials is studied, using additions of two types of super absorbent polymers (sodium polyacrylate and potassium polyacrylate) and a lightening material (vermiculite) in their manufacturing process.

Recovery of End-of-Life Tyres and Mineral Wool Waste: A Case Study with Gypsum Composite Materials Applying Circular Economy Criteria.

Characterization of a New Lightened Gypsum-Based Material Reinforced with Fibers.

This paper shows the characterization of a new lightened gypsum-based material for use in buildings. A plaster material has been designed with a polymeric compound based on polyvinyl acetate, bicarbonate and a boric acid solution, which reduce the density and thermal conductivity by up to 20% and 30%, respectively. In addition, tests have been carried out with the lightened plaster material reinforced with glass (GF), basalt (BF), polypropylene (PPF) and wood (WF) fibers.

Low-Cost Sensors for Determining the Variation in Interior Moisture Content in Gypsum Composite Materials.

Non-destructive testing can be used to determine some of the most relevant physical properties of building materials. In this work, two low-cost measuring devices were developed capable of determining the variation in real-time of the percentage of humidity that is produced in the construction of gypsum and plaster during the hardening process. For this, an Arduino resistive sensor and a capacitive sensor of our design were used.

New System of Shrinkage Measurement through Cement Mortars Drying.

Cement mortar is used as a conglomerate in the majority of construction work. There are multiple variants of cement according to the type of aggregate used in its fabrication. One of the major problems that occurs while working with this type of material is the excessive loss of moisture during cement hydration (setting and hardening), known as shrinkage, which provokes a great number of construction pathologies that are difficult to repair.

Mechatronic Prototype of Parabolic Solar Tracker.

In the last 30 years numerous attempts have been made to improve the efficiency of the parabolic collectors in the electric power production, although most of the studies have focused on the industrial production of thermoelectric power. This research focuses on the application of this concentrating solar thermal power in the unexplored field of building construction. To that end, a mechatronic prototype of a hybrid paraboloidal and cylindrical-parabolic tracker based on the Arduido technology has been designed.

Most buildings built during the nineteenth and early twentieth centuries were based on timber frame walls with vertical support elements. These timber frame elements are affected by their moisture content and by the passage of time.

Magnetic Sensors Based on Amorphous Ferromagnetic Materials: A Review.

Currently there are many types of sensors that are used in lots of applications. Among these, magnetic sensors are a good alternative for the detection and measurement of different phenomena because they are a "simple" and readily available technology. For the construction of such devices there are many magnetic materials available, although amorphous ferromagnetic materials are the most suitable.

Low-cost impact detection and location for automated inspections of 3D metallic based structures.

This paper describes a new low-cost means to detect and locate mechanical impacts (collisions) on a 3D metal-based structure. We employ the simple and reasonably hypothesis that the use of a homogeneous material will allow certain details of the impact to be automatically determined by measuring the time delays of acoustic wave propagation throughout the 3D structure. The location of strategic piezoelectric sensors on the structure and an electronic-computerized system has allowed us to determine the instant and position at which the impact is produced.

New system for measuring impact vibration on floor decking sheets.

Currently, there is a narrow range of materials that are used as attenuators of impact noise and building vibrations. Materials used in construction, such as elastic materials, must meet the requirement of having very low elastic modulus values. For the determination of the material's elastic modulus and the acoustic insulation of the same, costly and difficult to execute testing is required.

Magnetic sensor for building structural vibrations.

This paper shows a new displacement-to-frequency transducer based on the variation of a coil inductance when a magnetic core is partially or completely inserted inside. This transducer is based on a Colpitts oscillator due its low manufacturing price, behavior and immunity to noise. A tank circuit with a configuration in parallel was used because it can be employed at lower frequencies and it enables it to make a direct analysis.

A new self-calibrated procedure for impact detection and location on flat surfaces.

Many analyses of acoustic signals processing have been proposed for different applications over the last few years. When considering a bar-based structure, if the material through which the sound waves propagate is considered to be acoustically homogeneous and the sound speed is well known, then it is possible to determine the position and time of impact by a simple observation of the arrival times of the signals of all the transducers that are strategically disposed on the structure. This paper presents a generalized method for impact detection and location on a flat plate, together with a calibration procedure with which to obtain the sound speed from only one set of measurements.

Update on common indicators of nutritional status: food access, food consumption, and biochemical measures of iron and anemia.

This paper presents some of the most commonly utilized indicators to assess food and nutritional status. With respect to the indicators reflecting food access, those addressing poverty as well as food consumption are included. In addition, a variety of serum biochemical measures for the estimation of iron nutritional status and anemia are discussed; it is recommended that some of these be adjusted to account for sex, age, physiological status, and altitude above sea level.

Food-based nutrition interventions at community level.

The Food and Agriculture Organization of the United Nations promotes nutrition interventions considering food as the basis for action, given the strategic role of food and the agricultural sector to improve food security for the community; thus, a large number of people, especially the poor, who participate directly or indirectly in agricultural activities are able to obtain benefits from its multifunctional character. Food-based nutrition interventions have the purpose of improving food production and availability, processing and conservation, supply and commercialization, as well as access and food consumption. The basis of this focus is community and local government participation in the planning, execution, supervision and evaluation of specific interventions.

Phylogenetic analysis of a novel molecular isolate of spotted fever group Rickettsiae from northern Peru: Candidatus Rickettsia andeanae.

Phylogenetic analysis of five rickettsial genes (17-kDa gene, gltA, ompB, ompA, and sca4) from two molecular isolates of Candidatus Rickettsia andeanae from two ticks (Amblyomma maculatum and Ixodes boliviensis) collected from two domestic horses living in two separate locations in northern Peru (Coletas and Naranjo) was conducted to more clearly characterize this recently reported novel spotted fever group (SFG) rickettsia. Following nested polymerase chain reaction (PCR) amplification of the 17-kDa gene, gltA, ompB, ompA, and sca4, amplicons were purified, sequenced, and compared to those downloaded from GenBank. Phylogenetic analyses of the Candidatus Rickettsia andeanae sequences generated from 17-kDa gene (483 bp), gltA (1185 bp), ompA (1598 bp), ompB (4839 bp), and sca4 (2634 bp) demonstrated that they aligned strongly with those of SFG rickettsiae.

This information was necessary to design the nutrition education strategy.

[Determinants of success in nutrition and food security programs].

To gain a better understanding of factors which determine the effectiveness, efficiency and sustainability of community-based food and nutrition programmes, FAO has developed a conceptual framework and methodology to analyze these programmes. Based on selection criteria, 9 case studies were carried out in Latin America, Africa and Asia. The success factors associated with programme efficiency were analyzed in terms of these factors: enabling political environment; continuous awareness processes; community participation in programme planning, implementing and monitoring; measurable and time-bound objectives, management capacity of the programmes; participation of local non-governmental organizations; provision of basic services; association between the local government and the community to facilitate the shared ownership of the programme; and financial and technical arrangements necessary to ensure the sustainability of the results.
