El aceite de ricino, en muchas ocasiones mal traducido como aceite de castor por su denominación en inglés (castor oil), se obtiene a partir de la planta Ricinus communis, que contiene aproximadamente un 40-50 % del aceite.
Vibriosis causes an estimated 80,000 illnesses and 100 deaths in the United States every year. People with vibriosis become infected by consuming raw or undercooked seafood or exposing a wound to seawater. Most infections occur from May through October when water temperatures are warmer.
he fifth meeting of the Emergency Committee (EC) on Zika and microcephaly convened by the Director-General under the International Health Regulations (IHR 2005) regarding microcephaly, other neurological disorders and Zika virus was held by teleconference on 18 November 2016. The Committee was briefed on the implementation of the Temporary Recommendations issued by the Director-General on advice from the four previous EC meetings. The Committee was updated on the latest developments on Zika virus geographic spread, natural history, epidemiology, microcephaly and other neonatal complications associated with Zika virus, Guillain-Barré syndrome (GBS) and current knowledge on sexual transmission of Zika virus. The following States Parties provided information on microcephaly, GBS and other neurological disorders occurring in the presence of Zika virus transmission as well as control measures being implemented: Brazil, Thailand, and the United States of America. The Public Health Emergency of International Concern (PHEIC) declared by the Director-General of WHO has led the world to an urgent and coordinated response, providing the understanding that Zika virus infection and associated consequences represent a highly significant long-term problem that must be managed by WHO, States Parties and other partners in a way tha
El cerebro es el organo más importante de nuestro cuerpo, y tiene una actividad constante. Está constituido en su mayoría por células nerviosas llamadas neuronas y éstas necesitan el aporte contante de glucosa. Por otro lado tenemos los neurotransmisores que son sustancias que permiten la comunicación entre neuronas y se forman a partir de aminoácidos y otros nutrientes. Es por ello que la alimenntación ocupa un lugar muy importante en el desarrollo de nuestro cerebro. En ciertas ocasiones, como por ejemplo un aumento de actividad intelectual por estudio, trabajo, estres o por la edad, puede ser bastante beneficioso el incremento de ciertos nutrientes específicos. Los nutrientes específicos más destacados son las vitaminas de grupo B, algunos minerales, los ácidos grasos esenciales, fosfolípidos y aminoácidos. Las vitaminas del grupo B actúan en muchos procesos fisiológicos del sistema nervioso. En concreto el deficit de vitamina B1 se relaciona con problemas de concentración y poca memoria y la falta de vitaminas B3 y B6 puede ser causa de depresión. También existe mayor demanda de minerales como el Magnesio o el Zinc en situaciones de máxima exigencia intelectual y fisica. Nuestro cerebro es muy rico en grasa y por ello su buen funcionamiento se relaciona con la presencia de ácidos grasos esenciales. El más relevante es el DHA (ácido docosahexaenoico) de la serie Omega 3, presente en nuestras células y relacionado con el aprendizaje, la memoria y los procesos cognitivos.
nherited differences in taste perceptions may help explain why some people eat more salt than recommended, according to preliminary research presented at the American Heart Association's Scientific Sessions 2016. "Genetic factors that influence taste aren't necessarily obvious to people, but they can impact heart health by influencing the foods they select," said lead author Jennifer Smith, B.S.N., R.N., a Ph.D. student at the University of Kentucky College of Nursing. Previous research, according to the authors, showed that people who have one of the two most common variants of a gene (TAS2R38) that enhances bitter taste perception are likely to avoid heart-healthy foods with bitter properties, such as broccoli and dark leafy greens. In the current study, researchers sought to determine whether that bitter-enhancing genetic variations would also influence other food choices.
In 2014, Vermont passed the first legislation in the U.S. to require labeling of foods containing genetically engineered ingredients. A year earlier, Connecticut and Maine passed GMO labeling bills though these were dependent on several other states passing similar laws. Passages of these three bills were textbook examples of democracy in action. The state´s citizens lobbied their legislatures to introduce the bills, public hearings were held, experts spoke for and against the bills and lawmakers debated the measures. The bills ultimately passed because the lawmakers recognized that the People wanted them approved. Vermont´s bill passed overwhelmingly in both the state´s House of Representatives and Senate and Gov. Pete Shumlin signed the bill shortly thereafter.
Overview The core messages of the Five Keys to Safer Food are: keep clean; separate raw and cooked; cook thoroughly; keep food at safe temperatures; and use safe water and raw materials. The poster has been translated into more than 40 languages and is being used to spread WHO’s food hygiene message throughout the world.
Modern dental hygiene would have been quite unnecessary for ancient Romans living in Pompeii, as research has revealed that they had impressively healthy teeth. Scientists appointed by the Archaeological Superintendence of Pompeii have used CAT scans to examine 30 Pompeii inhabitants who were preserved in hardened ash after Mount Vesuvius erupted in AD 79. The group, headed by radiologist Giovanni Babino, released photos of their work on Sept. 29, and revealed in a press conference that the ancient Romans had perfect teeth and “no immediate discernible need for dentists,” according news agency Agenzia Giornalistica Italia. Though Pompeii citizens never used toothbrushes or toothpaste, they had healthy teeth thanks to their low-sugar diet. Massimo Osanna, superintendent of the World Heritage-listed site, said their diet was “balanced and healthy, similar to what we now call the Mediterranean diet,” according to The Telegraph.
Recent world attention has been drawn to a global Zika virus (ZIKV) outbreak and its link with devastating cases of microcephaly and Guillain-Barre syndrome. ZIKV infection is spreading rapidly within the Americas after originating from an outbreak in Brazil (Campos et al., 2015). Mounting evidence suggests that ZIKV infection in pregnant women can cause congenital abnormalities as well as fetal demise (Calvet et al., 2016, Cugola et al., 2016, Miner et al., 2016, Wu et al., 2016). Initial case descriptions of microcephaly and spontaneous abortions have been supported by evidence of viral RNA and antigen in the brains of congenitally infected fetuses and newborns (Martines et al., 2016, Mlakar et al., 2016).
