Obesity: Nutrition and Genetics—A Short Narrative Review  [PDF]
José M. Tallon, Janine Narciso, Ana Barros, Ana Pereira, Aldo M. Costa, António J. Silva
Health (Health) , 2018, DOI: 10.4236/health.2018.1012134
Abstract: Obesity has become a major global health challenge and it is a risk factor for the development of several comorbid conditions. Additionally, obesity has considerable economic consequences. Obesity is a multifactorial condition that arises from independent influences of genetic and social-environmental factors on food intake and physical activity. It has been difficult to establish clear associations between weight status and the intake of single foods or food groups. In most people, the predisposition to obesity has a polygenic basis, which means that obesity will develop if an individual has several polygenic variants that increase body weight. The FTO gene was the first GWAS-identified obesity-susceptibility gene and since then other polygenic variants that are associated with BMI and dietary intake have also been identified. However, this is still an active area of research as more polygenetic variants await discovery.

Safwat Mohd. El-Hoseny, Pierre Basmaji, Gabriel Molina de Olyveira, Ligia Maria Manzine Costa, Abdulwahid M. Alwahedi, José Domingos da Costa Oliveira, Gino Bruno Francozo
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2015, DOI: 10.4236/jbnb.2015.64022
Abstract: Bacterial cellulose (BC) can be used in wide area of applied scientific, especially for tissue regeneration and regenerative medicine, lately, bacterial cellulose mats are used in the treatment of skin conditions such as burns and ulcers, because of the morphology of fibrous biopolymers serving as a support for cell proliferation, its pores allow gas exchange between the organism and the environment. Moreover, the nanostructure and morphological similarities with collagen make BC attractive for cell immobilization, cell support and Natural Extracellular Matrix (ECM) Scaffolds. In this scope, Natural ECM is the ideal biological scaffold since it contains all the components of the tissue. The development of mimicking biomaterials and hybrid biomaterial can further advance directed cellular differentiation without specific induction. The extracellular matrix (ECM) contains several signals that are received by cell surface receptors and contribute to cell adhesion and cell fate which control cellular activities such as proliferation, migration and differentiation. As such, regenerative medicine studies often rely on mimicking the natural ECM to promote the formation of new tissue by host cells, and characterization of natural ECM components is vital for the development of new biomimetic approaches. In this work, the bacterial cellulose fermentation process is modified by the addition of vegetal stem cell to the culture medium and natural materials before the bacteria are inoculated. In vivo behavior using natural ECM for regenerative medicine is presented.

O papel da tributa??o diferenciada dos combustíveis no desenvolvimento econ?mico do estado de S?o Paulo
Costa, Cinthia Cabral da;Guilhoto, Joaquim José M.;
Economia Aplicada , 2011, DOI: 10.1590/S1413-80502011000300002
Abstract: this paper shows that the state of s?o paulo, by having a deliberated policy of different rates of taxation related to the consumer tax (icms) for gasoline c (25%) and hydrous ethanol (12%) has had a positive impact over: a) the consumption of ethanol; b) the economy of the state; and c) in the brazil economy. to do so this study uses: a) an interregional input-output system for s?o paulo and rest of brazil; and b) price and cross price-elasticity of the demand for gasoline and ethanol. the model was used to estimate how the economy would have behaved (gdp, employment, gross output, imports, and government revenue), had the rates of ethanol and gasoline being kept equal (25%).
La deformación craneana en la población prehistórica de Coyo Oriente, San Pedro de Atacama
Costa,M. Antonietta; Llagostera,Agustín; Cocilovo,José A;
Estudios atacame?os , 2008, DOI: 10.4067/S0718-10432008000200003
Abstract: the aim of this paper is to characterize one of the atacama basin's representative populations of the middle period and the possible arrival of foreign groups associated to tiwanaku expansion. the cranial collection from the coyo oriente cemetery, housed at the museo arqueológico de san pedro de atacama, was hence analyzed for its sex, age and intentional deformation patterns. these analyses were applied to the entire collection as well as to the three mortuary zones of the cemetery identified by le paige, that would represent a chronological occupation sequence. further comparison between the two groups (one supposedly local, the other foreign) was achieved bymeans of the sites' textile component, as described by oakland in 1992.

Abstract: this study was carried out from march to september 2000, in petrolina, pe rnambuco state, brazil, to evaluate the influence of nitrogen and potassium levels on yield characteristics and post-harvest quality of onion bulbs (allium cepa l.). the cultivar franciscana ipa-10 was used. the experimental design was a randomized complete block in a 4 x 3 factorial scheme, involving four levels of nitrogen (0; 60; 120 and 180 kg ha-1) and three levels of potassium (0; 90 and 180 kg ha-1) with three replications. the commercial yield showed a linear effect in the absence of potassium fertilization, while the levels of 90 and 180 kg ha-1 of potassium provided maximum yield with the levels of 175.8 and 169.4 kg ha-1 of nitrogen. increasing the doses of nitrogen resulted in a reduction of the non-commercial yield (culls). in the absence of potassium fertilization, a linear effect was obtained as a result of the levels of nitrogen for fresh mass of the bulb. for the levels of 90 to 180 kg ha-1 of potassium, the highest yield of fresh mass of the bulb was obtained with the level of 153.3 kg ha-1 of nitrogen. the levels of nitrogen influenced the classification of commercial bulbs of onion and the largest percentage of bulbs of the class 3 (85,8%) corresponded the dose of 153,6 kg ha-1 of nitrogen. no significant mass loss occurred after 20 days and only after 40 and 60 days after cure did any significant effects become evident and there was no interaction between the levels of nitrogen and potassium.
