Cancer is a very serious health problem affects huge number of people around the globe, up to date there is no known treatment to cancer due to diversity of disease and unknown etiology of cancer. I think that cancer occurrence must be attributed to microbes which person gains after birth. To confirm that theory we should conduct many laboratory and clinical investigations involving large sample size with different age group and various risk factors and then examine the relation between microbe and cancer.

Epidemiology of Onychomycosis in Pernambuco, Northeastern of Brazil: Results of a Laboratory-Based Survey_Crimson Publishers

Epidemiology of Onychomycosis in Pernambuco, Northeastern of Brazil: Results of a Laboratory-Based Survey by Patrícia Cristina Rodrigues in Cohesive Journal of Microbiology & Infectious Disease

Onychomycosis is chronic ungual disease that affects people worldwide and whose prevalence has been increasing in recent decades. Among the etiological agents are yeasts, dermatophytes and non-dermatophytid filamentous fungi (NDFF). The symptoms and severity can vary widely according to the anatomic site, condition of the individual and geographic location. Laboratory identification of the fungal etiological agents is necessary due to the wide variety of these agents and the varied responses to the existing drugs. This study aimed to diagnose and characterize epidemiologically onychomycosis, besides of to determine the susceptibility profile against evaluable antifungals drugs. Patients of a Dermatological Public Service of reference at Recife city, Northeast of the Brazil, which were suffering from suggestive lesions were evaluated between August 2016 and July 2017. Mycological diagnosis was carried out by direct microscopic examination of clinical samples clarified with 20% potassium hydrochloride (KOH) and by culture in Sabouraud dextrose agar medium supplemented with 2% (v/v) chloramphenicol. After incubation for 15 days at 35-37 °C, the macro and microscopic aspects of the colonies were analyzed for specie identification. The yeasts were identified by proteomic analysis with MALDI-TOF MS. In vitro antifungal susceptibility testing was carried out according CLSI method. Signs and symptoms suggestive of onychomycosis were presented in 196 patients, of which were obtained 224 nail samples. In the mycological tests,

Interest in alternative fuel sources to oil has fluctuated throughout contemporary history according to the availability of this resource. The biggest impact of the reduction in the supply of oil is the increase in the price of the barrel practiced in the international market.

The first oil shock in 1973 showed that the price of the barrel rose rapidly, from US $ 2.90 /barrel to US $ 11.65/barrel in three months, causing enormous losses in the economy of countries that do not have strategic oil and gas reserves (e.g.: Germany, France and Italy).

In the late 1970s amid the second oil shock, when the price of a barrel of oil exceeded US$ 80.00, renowned German and Italian scientists began research to obtain microalgae fuels - notably from Tetraselmis sp - in southern Italy.

Throughout the 1980s, with the normalization of oil prices in the international market, the interest for fuels from microalgae was very low and the activities of microalgae cultivation were directed to aquaculture, nutraceutical production and fine chemical compounds, highlighting the genera Chlorella and Dunaliella, as well as the cyanobacterium of the genus Arthrospira.

It is important to note that even during this period with less demand for microalgae fuels the US government did not cease its investments and promoted research and development activities to obtain products such as ethanol and biodiesel over 15 years through the Aquatic Species Program. A new moment arose between 2008 and 2009 when the price of oil surpassed US $ 120/barrel, making the interest in research and development focused on microalgae fuels resurface once more on the international scene.

Since then, new governmental incentives have been allocated in several countries, A. Mainly in the USA through the National Renewable Energy Laboratory. It has given a considerable boost to many universities and small companies with expertise in micro-algal biotechnology.

Several projects aimed at obtaining microalgae biomass were developed using photobioreactors, open ponds or heterotrophic culture technologies in bioreactors in the absence of light. Among the main scientific problems presented during the upstream projects were the high cost of investment for photobioreactors and the difficulty in achieving stability and high productivity in open ponds.

As regards the processing of microalgae biomass, there were also several research and development projects aimed at improving the efficiency and cost-effectiveness of the steps of harvesting, cell disruption, extraction and conversion of the target compounds into biofuels (e.g.: ethanol, biodiesel and jet fuel).
