Derecho a la salud de la población desplazada: el caso de las mujeres del Auto 092, medellín, antioquia
Fernández-Moreno,Sara Yaneth;
Revista Gerencia y Políticas de Salud , 2010,
Abstract: medellin is the second largest city in the reception of internally displaced population, product of the armed conflict of the country. even though sexual violence in this context is a state crime against humanity without limitations of power to prosecute, the country is barely beginning actions to undertake the problem, together with the processes of reparation, restitution and non-repetition, from differential treatment and gender-sensitive approaches. it is crucial to approach sexual violence from the actors of the armed conflict through the recognition of health as a fundamental human right, and from the gender-sensitive and socio-sanitary perspectives. however, in the advancement made so far, it can be argued that the essential guaranties of the right that these women have -in their condition of victims- become scarcely administrative, and they have a high risk of being re-victimized, in a process whereby the different governmental instances -including the instances of health care in charge of the attention to this population- do not keep the minimal attention protocols in the particular circumstances of these women.
Changes in epilithic diatom assemblages in a Mediterranean high mountain lake (Laguna de La Caldera, Sierra Nevada, Spain) after a period of drought
Journal of Limnology , 2008, DOI: 10.4081/jlimnol.2008.49
Abstract: The epilithic diatom assemblages studied in the high mountain lake “La Caldera” (Granada, Spain) from 1996 to 1998 went through two clearly different stages. The initial one, in 1996, corresponded to the reflooding of the basin after a severe drought and was composed mainly of the colonising species Fragilaria rumpens, together with a lesser presence of Nitzschia sublinearis and Hantzschia amphioxys. The predominant presence of F. rumpens at the end of the summer of 2006 coincided with low species diversity (values of Shannon and Wiener Index: 0.3-0.6). During the following two years another assemblage established itself, dominated by Achnanthidium minutissimum, which is considered to be more stable and widespread among the lakes of the Sierra Nevada. The most notable subdominant species (less than 20% of relative abundance) in this assemblage were: Encyonema minutum, Encyonopsis microcephala and Navicula cryptocephala. The diversity values during this second period were much higher than in the first: 1.0-2.2. Nutrient concentrations were measured separately in the limnetic (epilimnetic) and benthic (epilithic) environments. These abiotic parameters show that the dynamics of ammonia and silica were much the same in both, showing a gradual decrease from the beginning to the end of the study period. Epilimnetic phosphorus followed a similar pattern to ammonia and silica. In the epilithon, nitrates and phosphates increased during the first year, only to descend notably during the second. The effect of other environmental parameters such as temperature and the preceding drought on the dynamics of the diatom assemblage are discussed. Ratio DIN:SRP let us test the different degrees of phosphorus limitation in epilithon and epilimnion environments; our results suggest that phosphorus limitation of primary production in high mountain lakes is much more severe in the limnetic environment that it is in the epilithon.

Abstract: Stroke and diabetes mellitus are two separate conditions which share multiple common threads. Both are increasing in prevalence, both are diseases which affect blood vessels, and both are associated with other vascular risk factors, such as hypertension and dyslipidemia. Abnormal glucose regulation, of which diabetes is one manifestation, is seen in up to two-thirds of people suffering from an acute stroke. Surprisingly, aggressive management of glucose after an acute stroke has not been shown to improve outcome or reduce the incidence of further strokes. More encouragingly, active management of other cardiovascular risk factors has been demonstrated to prevent stroke disease and improve outcome following a stroke in the diabetic person. Hypertension should be treated with a target of 140/80?mmHg, as a maximum. The drug of choice would be an ACE inhibitor, although the priority is blood pressure reduction regardless of the medication chosen. Lipids should be treated with a statin whatever the starting cholesterol. Antiplatelet treatment is also essential but there are no specific recommendations for the diabetic person. As these conditions become more prevalent it is imperative that the right treatment is offered for both primary and secondary prevention in diabetic people, in order to prevent disease and minimize disability. 1. Introduction Diabetes mellitus (DM) is a common problem whose prevalence is increasing due to population aging and the growing problem of obesity. According to the World Health Organization (WHO), the prevalence of diabetes for all age groups worldwide is estimated to be approximately 2.8%, and the total number of people with diabetes is projected to rise from 171 million in 2000 to 366 million in 2030 [1]. In the United States alone over 23 million people have diabetes, and the number of people with diabetes diagnosed is estimated to increase 165% between 2000 and 2050 [2]. Abnormal glucose regulation can occur in a number of different clinical situations: diabetes, impaired glucose tolerance (IGT), or in times of acute illness. Diabetes is the clinical condition present when glucose is chronically raised. It can remain undiagnosed in asymptomatic individuals while remaining a risk factor for the development of stroke. IGT is a condition where glucose is not regulated properly but remains at levels below that of frank diabetes. Individuals are usually asymptomatic but remain at increased risk of diabetic complications and the condition often proceeds the development of diabetes. In times of medical stress blood glucose also

Theoretical and Empirical Researches in Urban Management , 2009,
Abstract: The present work organizes information in a systematized way, on environmental technologies applied to each of the tasks and activities that are performed in the cities, urban planning and development. These technologies are an updated part of all the technologies that can be applied, therefore, it is the state-of-the-art of new technologies applied to urban sustainable development which mostly are processes, instruments of measurement, simulators, equipment, materials, Software and Hardware that are of great help for urbanism designers and promoters of urbanism in the cities development. These technologies, which are described in the present article, have been selected on the basis of their up-to-dateness and application in the main sectors or fields of development and it is important to mention that only the most recent and influential on urban development and environmental technology have been chosen. The main objective is to provide an overview of the state-of-the art of these environmental technologies, and how we, designers, architects and promoters of urban development, can apply and use a number of technologies in urban planning with an environmental approach.

Abstract: RESUMEN.- Este estudio examinó la específica organización del juego de ataque en balonmano femenino. En concreto, hemos explorando el peso específico de los dos posibles tipos de ataque: posicional y contraataque. Para ello, hemos analizado los partidos de un mismo equipo de División de Honor Femenina durante la temporada 2008/2009 mediante metodología de la observación sistemática, directa y no participante. Hemos estudiado más de 2000 jugadas de ataque y 900 lanzamientos a portería, determinando de esta manera los índices de efectividad. El análisis estadístico reveló que existe una mayor eficacia del contraataque frente al juego posicional, además de una mayor relación con la victoria final. ABSTRACT.- This study focuses on the specific organization of the attacking strategies in women's handball. In particular, we explore the specific weight of the two possible modalities of attack: positional and counterattack. To do so, during the 2008/2009 season, we have analyzed through a systematic observation methodology, direct and non-participant, the matches of a team that plays in the First Division of Women's Handball. To determine the rates of effectiveness, we have studied more than 2000 attacks and 900 throws on goal. Statistical analysis revealed that counterattack is more effective than positional play, and that it has a closer relationship with victory.

Abstract: The telomere length of PBL was analyzed in DNA samples from 166 healthy controls (114 J and 52 non-J) and 79 OA patients (41 J and 38 non-J) by means of a validated qPCR method. The NO production was assessed in 7 carriers of the haplogroup J and 27 non-J carriers, by means of the colorimetric reaction of the Griess reagent in supernatants of cultured chondrocytes. Inducible nitric oxide synthase (iNOS) mRNA from these samples was analyzed by qPCR. Appropiated statistical analyses were performedCarriers of the haplogroup J showed a significantly longer telomere length of PBLs than non-J carriers, regardless of age, gender and diagnosis (p = 0.025). Cultured chondrocytes carrying the mtDNA haplogroup J also showed a lower NO production than non-J carriers (p = 0.043). No significant correlations between age and telomore length of PBLs were detected neither for carriers of the haplogroup J nor for non-J carriers. A strong positive correlation between NO production and iNOS expression was also observed (correlation coefficient = 0.791, p < 0.001).The protective effect of the mtDNA haplogroup J in the OA disease arise from a lower oxidative stress in carriers of this haplogroup, since this haplogroup is related to lower NO production and hence longer telomere length of PBLs too.Osteoarthritis (OA), the most common form of joint disease and cause of musculoskeletal disability in elderly people, is a disease affecting articular cartilage, bone and soft tissue leading to joint destruction and severe impairment of mobility [1]. It is also the main cause of work incapacity and one of the most common reasons for visiting primary physicians. The metabolic and structural changes that take place in the articular cartilage, including the reactive oxygen and nitrogen species (RONS), are thought to play a main role in the initiation and progression of this disease.A growing body of evidence suggests that oxidative damage, due to the overproduction of nitric oxide (NO) and other rea
Using thermal analysis to evaluate the fire effects on organic matter content of Andisols

Abstract: Soil organic compounds play a relevant role in aggregate stability and thus, in the susceptibility of soils to erosion. Thermal analysis (N2 and air) and chemical oxidation techniques (dichromate and permanganate oxidation) were used to evaluate the effects of a forest fire on the organic matter of Andisols. Both thermal analysis and chemical methods showed a decrease in the organic matter content and an increase in the recalcitrance of the remaining organic compounds in the burned zones. Thermal analysis indicated an increase in the thermal stability of the organic compounds of fire-affected soils and a lower content of both labile and recalcitrant pools as a consequence of the fire. However, this decrease was relatively higher in the labile pool and lower in the recalcitrant one, indicative of an increase in the recalcitrance of the remaining organic compounds. Apparently, black carbon did not burn under our experimental conditions. Under N2, the results showed a lower labile and a higher recalcitrant and refractory contents in burned and some unburned soils, possibly due to the lower decomposition rate under N2 flux. Thermal analysis using O2 and the chemical techniques showed a positive relation, but noticeable differences in the total amount of the labile pool. Thermal analysis methods provide direct quantitative information useful to characterize the soil organic matter quality and to evaluate the effects of fire on soils.
Exotic and conventional superconductivity in a Dirac supersymmetric scheme

Physics , 1994,
Abstract: A new pairing theory for many-fermion systems is obtained via the Dirac supersymmetry framework recently introduced to describe Dirac particles in external potentials. It is shown that the standard Bogoliubov-Valatin canonical transformation treatment of the quasi-particle BCS singlet pairing mechanism naturally falls within this framework. Straightforward generalizations in which the fermions can be ascribed $ \nu$ {\it components} are shown to lead to enhanced gap energies and critical temperatures as in the case of cuprate superconductors without invoking a stronger electron-boson coupling. The new $T_{c}^{max}$ limit is $T_c^{max} = \nu T_c^{BCS}$, with $T_c^{BCS} \approx 40^0 K$.
