A project to fight pulmonary hypertension

A project called Enpathy has launched a crowd funding platform to sponsor research

Pulmonary hypertension is a rare disease that affects lung arteries causing their progressive narrowing. Diagnosis generally occurs late, when treatment options are less, because there are not any diagnostic tools for early detection. On the occasion of the World Pulmonary Hypertension Day on May 5th, the Fundación Contra la Hipertensión Pulmonar (FCHP), a foundation against pulmonary hypertension, has launched a crowd funding platform to sponsor a research project called Enpathy; its main objectives are to facilitate early diagnoses and to find a definitive cure. The project involves scientists from several Spanish hospitals and universities, the Universidad de Valladolid, for instance.

The origin of Alzheimer’s disease may be in Homo sapiens’ evolution

A study published in Journal of Alzheimer’s Disease suggests that our vulnerability to neurodegenerative conditions is a price to be paid for our cognitive abilities

Emiliano Bruner, researcher at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) –a research center on human evolution in Burgos, Spain-, and Heidi Jacobs, from the Forschungszentrum Jülich –an institute of neuroscience and medicine in Germany-, have published an article in Journal of Alzheimer’s Disease suggesting that vulnerability to neurodegenerative processes in our species, Homo sapiens, would be “the price to be paid for our cognitive abilities”. The hypothesis developed by both scientists incorporates information from paleoneurology (the study of the brain and the intracranial system by analysis of fossils), image analysis, comparative anatomy and neurophysiology.

Galectin- 1, a key molecule in cancer

The protein by tumours is produced in large quantities in order to form new blood vessels and eliminate defenses to grow and spread

All evidence supports the accusation. Investigators found in different types of cancer -breast, prostate, melanoma and Kaposi’s sarcoma- that tumor cells over express Galectin-1 (Gal-1) to develop, metastasize and prevent the immune system to eliminate them. “During the last ten years we found that, in broad terms, Gal-1 favours all mechanisms associated to tumor cell growth: it allows them to escape the immune system, create new blood vessels- angiogenesis- and migrate to form metastasis”, explains Gabriel Ravinovich, principal investigator at the Institute of Biology and Experimental Medicine (IBYME, CONICET- FIBYME), and director of the investigations team.

A gene helping fungi to attack plants

An article published in 'PLOS ONE' proves that a gene of plants was transferred to fungi ancestors of the Colletotrichum genus and currently makes them harmful to crops

Scientists from CIALE (a center for agricultural research at the Universidad de Salamanca, Spain) have published an article in the prestigious PLOS ONE contributing to fight diseases in plants of agricultural interest. The research team, led by Michael Thon, has identified a gene that passed from plants to ancestors of Colletotichum pathogenic fungi, a very harmful species to many crops. The presence of the gene could make attacks to plants easier.

Factors causing eye dryness in contact lens wearers

Looking for nearsighted volunteers with up to 5.00 diopters, wearing contact lenses or not, to be part of this study

According to estimates, half of the people giving up contact lenses are motivated by discomfort linked to eye dryness. The optical industry has been working to solve this problem and to reduce these high percentages, to do so, it is necessary to delve into all factors associated with eye dryness and its effects on contact lenses. Researchers from the GSO (Eye Surface Team) at the IOBA (an institute of applied ophthalmology) in Valladolid (Spain) are working on this area and are currently developing a study with 60 patients.

Nitrate and other elements in Spanish bottled and running water

This study is part of the MCC-Spain project that aims to analyze the influence of environmental factors and their interaction with genetic factors in tumors

A research team at the Ibiomed (an institute of biomedicine at the Universidad de León, Spain) has collaborated in an article recently published in Gaceta Sanitaria, a journal edited by the Sespas (a Spanish body of public healthcare and health management); the article analyzes levels of nitrate and other elements in bottled and municipal water in Spain. The study concludes that the amount of nitrate in municipal water does not exceed legal levels but differs depending on regions; and trace elements such as arsenic, nickel and cadmium are present in such small amounts that are unquantifiable in almost all samples, for both running water and bottled water.

Eco-design to reduce environmental impact of electric vehicles

This initiative, coordinated by Cartif, has focused on the main components of electric vehicles and charging points

Eco-design is a practice incorporating environmental factors into the decision making process during the development of a product, as an additional factor to those traditionally taken into account such as cost and quality. In order to include this outlook to electric vehicles, Cartif, a technological center in Valladolid (Spain), has coordinated an European project called Green Car Eco-design, an initiative born at the project Interreg IV-B SUDOE involving seven Spanish, French and Portuguese partners. This project, finished in the first week of April, has been carried out during the last two years with a 1.17 million budget.

Objective tests to assess hearing impairments

Spanish scientists have conducted the study for an American company and now they are improving the technique. Main goal: tailored hearing aid.

Thanks to the funding granted by an American company called Starkey, the Instituto de Neurociencias de Castilla y León (INCYL), an institute of neuroscience at the Universidad de Salamanca , has performed tests, during two years, with patients suffering from bilateral sensorineural hearing loss, a common hearing impairment in older people. The ultimate goal is to understand why a hearing-aid device is more effective in some patients than in other with the same hearing problem. This new project aims to make tests faster and more objective measuring brain activity with electrodes. Instead of having many consultations during months, a few minutes will be enough to carefully explore patients.

Amphibian and reptile fossils to study climate changes

Knowing past climate features and variations is essential to determine the circumstances of human evolution in Europe

Knowing climate’s history on Earth is paleoclimatologists’ major objective. These scientists use different techniques to calculate their estimates, as in the case of the analysis of polar ice sheets, tree rings and sediments. Members of the Equipo de Investigación de Atapuerca (EIA) – Atapuerca Research Team- are working on this area: they have studied for years climate evolution from microfauna remains found in paleontological sites at the Atapuerca Mountains, Spain.

Two types of cells triggering brain tumors have been identified

The Centro de Investigación del Cáncer (Salamanca, Spain) and the Hospital de Valdecilla (Cantabria, Spain) have found potential mechanisms for therapies to prevent glioblastoma recurrence

A study proved the existence of two types of tumor stem cells producing glioblastomas, the most aggressive brain tumors. On one hand, a type of cancer-triggering cells are in the tumor mass; on the other, another group of cells with greater mobility placed on tumors spreads and, as these cells cannot be removed by surgery, recurrences occur. This finding has been published in Stem Cells and it is considered the first step to develop therapies preventing cancer recurrence.
