Dose specification for hippocampal sparing whole brain radiotherapy (HS WBRT): considerations from the UK HIPPO trial QA programme
Authors: Megias Daniel , Phillips Mark , Clifton-Hadley Laura , Harron Elizabeth , Eaton David J , Sanghera Paul , Whitfield Gillian 
Published: January 2017

Objective:
The HIPPO trial is a UK randomized Phase II trial of hippocampal sparing (HS) vs conventional whole-brain radiotherapy after surgical resection or radiosurgery in patients with favourable prognosis with 1–4 brain metastases. Each participating centre completed a planning benchmark case as part of the dedicated radiotherapy trials quality assurance programme (RTQA), promoting the safe and effective delivery of HS intensity-modulated radiotherapy (IMRT) in a multicentre trial setting.

Methods:
Submitted planning benchmark cases were reviewed using visualization for radiotherapy software (VODCA) evaluating plan quality and compliance in relation to the HIPPO radiotherapy planning and delivery guidelines.

Results:
Comparison of the planning benchmark data highlighted a plan specified using dose to medium as an outlier by comparison with those specified using dose to water. Further evaluation identified that the reported plan statistics for dose to medium were lower as a result of the dose calculated at regions of PTV inclusive of bony cranium being lower relative to brain.

Conclusion:
Specification of dose to water or medium remains a source of potential ambiguity and it is essential that as part of a multicentre trial, consideration is given to reported differences, particularly in the presence of bone. Evaluation of planning benchmark data as part of an RTQA programme has highlighted an important feature of HS IMRT dosimetry dependent on dose being specified to water or medium, informing the development and undertaking of HS IMRT as part of the HIPPO trial.

Advances in knowledge:
The potential clinical impact of differences between dose to medium and dose to water are demonstrated for the first time, in the setting of HS whole-brain radiotherapy.

A theoretical model of infiltration kinetics based on the Darcy's law which was evaluated by W − Lambert function has been established for Cu-Ni-Mn alloy (grade MNMts 60-20-20) during melt infiltration into Cr3C2 porous skeletons with different morphology. It is shown, that theoretical calculations are in good correlation with experimental data obtained by pressureless infiltration of carbide preforms with open porosity 20-40 vol. % at 1200 °C. Calculations shows that infiltration height dependence on the average size of carbide particles is described by curves with a maximum which corresponds to~ 60 μm for specified system with carbide skeleton porosity of 40 vol. %.

Published: January 2017

On the two-dimensional model of the crystal it was shown that the crystal lattice transform from stable to unstable under the influence of hydrostatical high pressure. As a result of such transformation is intensity the processes of plastic deformation.
It is known that all of solid bodies become plasticity and electric conductivity under the influence of a hydrostatical high-pressure. The reason of it is additional displacement of atoms of a crystal lattice. A high plasticity and electric conductivity of metals occurs due to additional displacement of atoms also. This displacement takes a place due to the specific of the interatomic interaction.

Experience has shown that even periodic shooting does not give the desired effect, ie. A. The bird population is very mobile and able to move quickly scattered and maneuvering that practically negates all efforts for their physical elimination. The use of poisoned baits is prohibited and is ineffective, t. To. Various species of birds have different food preferences. Our research is devoted to finding a solution to this problem. As the main operational measures for scaring birds we offer the use of bio-acoustic instrument with a sound recording, effectively acting on air flight hazard species of birds, including corvids and Black Kite, which are not optional in many similar devices. Application of bioacoustics devices does not require an additional set of fireworks scare, but also an integral character of the device significantly increases the efficiency of the impact on birds and allows for a few minutes to eliminate concentrations of birds in large areas.</p><p>The study analyzed information on aircraft collisions with birds, considered the scheme of air traffic, as well as the general plan for the landfill site, the Civil Aviation documents ornithological flight operations, carried out the operational test site survey.

<p> </p><p>The spleen is an important multifunctional organ, one of parts of the peripheral immune system and hematopoiesis. It is sensitive to biotic, abiotic, and environmental factors. Determination of morphological features and morphometric parameters are important for the development of organ test-systems. The major indicators are the relative weight of the spleen and its main structural components. These criteria could be used in the therapy, prevention, pathology, the study of influence of factors of different origins, for received from farm animals environmentally friendly and safe products. Our research was carried out by light microscopy with the production of permanent histological preparations. The formalin and Сarnoy liquid were used as fixatives. Paraffin sections were stained with hematoxylin, eosin, and azure by methods of Van Gieson and Brachet. Spleen has the same structure and principle consists of a support-contractile apparatus and pulp in birds and mammals. Each animal species had its own characteristic of morphological features. The relative weight of spleen was the greatest in horses (0.48±0,01 %) and the lowest was in pigeons (0.02±0.01 %). Support-contractile apparatus was better developed in horses (13.64±1.13 %) and sheep (12.08±0.42 %), and the lesser in chickens (3.02±0.95 %) and rabbits (5.87±0.69 %). The proportion of trabecular system prevailed on the proportion of capsules in all studied animals, except rabbits. The birds had no radial trabeculae, in rabbits they are insignificant. The number of capsular trabecular are lesser than the pulps in horses, pigs, and sheep. Large pulps` trabeculae are united together, forming trabecular tree, while parenchyma is formed by the white and red pulp. The main structural components of the white pulp are the lymphoid nodules and lymphoid sheath near the vessels. The lymphoid nodules have zonal structure in mammals, whereas they are absent in birds. The relative area of lymphoid nodules in animals dominates under the area of lymphoid sheaths near the vessels; this difference was more than twice in horses (5.01±0.63 and 2.41±0.17 %), rabbits (11.95±2.67 and 5.73±1.40 %). In all the studied mammals the light center had the largest relative area in rabbits (2.08±0.49 %), and the lowest was registered in horses (0.98±0.11 %). The marginal zone occupies the largest relative area in sheep (6.52±0.98 %), the least – in horses (2.02±0.12 %). The mantle zone and zone near the vessels were better developed in rabbits (3.36±0.76 and 2.41±0.84 %); the red pulp was better developed in chickens (78.30±1.98 %), pigs (78.87±2.36 %) and horses (78.94±4.39 %), while sheep had the lesser developed red pulp (69.99±1.0 %).</p>

Authors: Castro Espinoza Patricia , Castillo Arredondo Santiago 
Published: January 2017

El emprendimiento radica en tomar a cargo un problema o anomalía que se ha detectado en el entorno a fin de contribuir con una solución ideal a través de una empresa. Se desarrolla con los recursos reproducidos por el ambiente durante el proceso creativo de implementación de la idea y que beneficia la calidad de vida de la colectividad. Cuando en este entorno se accede a los recursos como formación, oportunidades de negocios inclusivos, crédito, tecnología de información, u otros, se incrementan las innovaciones acelerando su crecimiento. En nuestra investigación se aplicó un enfoque cualitativo para desarrollar una evaluación identificando categorías de conocimiento con agentes de asistencia técnica pública a empresas y emprendimiento en un escenario de investigación integrador y actual en los centros de desarrollo empresarial, como apoyo al emprendimiento donde emergieron las competencias en la formación de nuevas empresas innovadoras (Albert-Gómez, 2007; Hernández, 2006). Entre los hallazgos de la investigación aparece que la formación en comportamiento innovador y la creación de empresas debe contribuir al desarrollo de competencias como la gestión de equipos de trabajo y el manejo desde la idea de un plan de negocios, al amparo del cuerpo legal y las políticas que fomenta el desarrollo endógeno del territorio. El creciente flujo de datos obliga a retomar la formación de estas competencias. En este marco la evaluación será el eje dinamizador del proceso de aprendizaje que se debe extender a lo largo de toda la vida (Castillo-Arredondo, Torres-González y Polanco-González, 2009; Cabrerizo-Diago, Rubio-Roldán y Castillo-Arredondo, 2008).

Background: Among the inherited disorders of blood, haemoglobinopathy and thalassaemia constitute a major bulk of congenital hemolytic anemia in India.Methods: The present cross sectional study was conducted on pediatric patients aged 0-15 years admitted in pediatric ward of Department of Pediatrics, MGM Medical College and LSK Hospital, Kishanganj, Bihar, India between December 2015 to November, 2016. The data on socio-demographic profile, relevant clinical history and examination and hematological parameters were assessed. Results: Out of 211 patients evaluated, most common cause of congenital hemolytic anemia was Hb E Beta thalassemia (39.8%), followed by beta thalassemia (27.9%), beta thalassemia trait (14.2%), Hb E disease (11.3 %) and Hb E trait (6.6%). There was male preponderance (male 63%, female 37 %). The mean hemoglobin was found to be lowest in patients of β thalassemia (5.1 gm/gl) and HbE β thalassemia (5.8 gm/dl). The mean total serum bilirubin was found to be highest among β Thalassemia patients (3.0 mg/dl). Hepatomegaly was the most common clinical finding among the study population (57.8%), followed by splenomegaly (54.9%) and hemolytic facies and jaundice (both 53%).Conclusions: The incidence of HbE beta thalassemia is relatively high in comparison to other varieties of thalassemias and is a major public health problem in this area of the country.
