Pharmacy and Biochemistry
Teachers seek to incorporate the algae Phorphila colombina to dry pasta, a massively consumed food. It is a renewable resource of the Patagonic coast with a high percentage of proteins, minerals, fibers and vitamins. The objective of the project is to favor the popularity of the algae among non-consumers, incorporating them to pasta, which constitutes an important dish from a nutritional and gastronomic point of view. The work was awarded a prize by the Foundation Arcor.
Through the project “Biomatter”, researchers developed a surgical kit to regenerate ulcerated or severely burned skin. The kit contains a high precision instrument to take skin samples, a device to separate the cells and a bio-absorbable membrane. The design won a millionaire subsidy.
The device designed will help to diagnose and analyze the evolution of certain diseases and create appropriate medication. The designs existent before the creation of this new instrument are complex and expensive. The new device built in our country with national materials will not only facilitate its use, but also its subsequent maintenance.
The extensive use of drugs spread by the media represents a danger which can cause serious consequences such as disability and even in extreme cases, death. This was indicated by Doctor Caterina Milone, specialist in pharmaco-epidemiology, who gave a lecture in the University where she developed the concept of pharmacy surveillance, which implies the follow up of the possible side effects of drugs.
The work of a group of researchers from the University and the Conicet is to understand how the defense system of the body avoids fertilization. They could identify the action of antibodies in some cases of infertility classified as “without apparent cause”. The scientists say that the routine techniques to detect infertility leave many possibilities out and that the immunological causes of infertility haven’t been taken into account appropriately.
The objectives of a team of researchers was to test different strategies to fight one of the most common pathogenic agents in dairy farms, to improve the animals’ health and reduce the use of antibiotics which leave residues in the milk and meat. In order to do that, they work in the formulation of a prophylactic vaccine against mastitis composed of regional isolated bacteria extract.
The mechanism by which the plants’ roots adapt to saline soils was worked out by a young researcher from the Conicet. The results of the study, which was awarded a prize as the best thesis work in Biochemistry and Molecular Biology in Latin America, might permit to select the leguminous varieties which tolerate these conditions or to generate transgenic agents to recover soils.
A new chemical entity, constituted by antibiotic molecules currently used, fluorquinolone ciprofloxacin and norfloxacin, might have an antibiotic effect higher than that of the individual constituents to face some kinds of bacteria. The research about this compound is developed in the School of Natural Sciences and the first tests indicate that its effect is appropriate to treat in a more effective way urinary, skin and eye infections, among others.
A biological technique to control vinchucas in the north of the province of Salta has shown optimal results in the elimination of the vector which transmits Chagas disease. It is a development for which it is used an endopathogenic fungus stump which is innocuous for the human population. In this zone, the vinchucas are resistant to traditional insecticides used to combat it and which besides, are damaging for the environment and the people.
Researchers from the School of Natural Sciences formed the team which contributed in the development of the vaccine against hydatidosis. After 25 years of research, the vaccine, called EG95, has one hundred percent of efficiency in the protection of cattle and sheep against this disease. Nowadays, scientists look for an antigen which immunizes people against hydatidosis.
The reagent will permit, in a very short time, to detect up to five different pathogenic agents which cause infantile diarrhea. In this way we will advance in the field of early detection of pathologies which can derive in Uremic Hemolytic Syndrome, among others. Besides, the quick identification of the bacteria will permit to avoid the neurological and kidney long-term effects which these microorganisms can cause.
Nanotechnology is an interdisciplinary science like none previously known and it seeps through almost all the technological branches of human activities. Its diffusion in the scientific field and its applications permit to discern a promising future as due to the great number of possible new products there are opened numerous opportunities for small and medium-sized industries. In an interview to InfoUniversidades Dr. Julio Raba analyzes the reach and future of the discipline.
It is unknown the cause by which metals, such as iron and copper are accumulated in the brain of people with Parkinson and Alzheimer. That is why a group of researchers of the Conicet analyzes the causes for this accumulation and makes enquiries in their link to the neuronal function. The results of the project could contribute to the comprehension of the mechanisms which operate in neurodegenerative diseases.
Cotinine is one of the alkaloids present in tobacco and it is also a metabolite of nicotine. Experimental studies in rats showed that in the long term, cotinine might be responsible for hyperglycemia and vasculitis developed by smokers. The data are the result of a research work carried out in the UBA, by means of which it was also developed a method which permits to isolate cotinine and quantify the compound in the blood and urine.
People migrations, promoted by the new transport means or due to working reasons, not only permit humans’ transfer, but also the transmission of parasite diseases from one region to another and from one country to another. Dr. Sixto Raúl Costamagna, Professor of Clinical Parasitology of the Universidad Nacional del Sur talked about this phenomenon called “Parasitic disease Globalization”.
