Methylmercury Effect and Distribution in Two Extremophile Microalgae Strains and from Andalusia (Spain).

The main entrance point of highly toxic organic Hg forms, including methylmercury (MeHg), into the aquatic food web is phytoplankton, which is greatly represented by various natural microalgal species. Processes associated with MeHg fate in microalgae cells such as uptake, effects on cells and toxicity, Hg biotransformation, and intracellular stability are detrimental to the process of further biomagnification and, as a consequence, have great importance for human health. The study of MeHg uptake and distribution in cultures of marine halophile and freshwater acidophilic alga demonstrated that most of the MeHg is imported inside the cell, while cell surface adhesion is insignificant.

The Effect of Oil-Rich Food Waste Substrates, Used as an Alternative Carbon Source, on the Cultivation of Microalgae-A Pilot Study.

Microalgae are mostly phototrophic microorganisms present worldwide, showcasing great adaptability to their environment. They are known for producing essential metabolites such as carotenoids, chlorophylls, sterols, lipids, and many more. This study discusses the possibility of the mixotrophic abilities of microalgae in the presence of food waste oils.

Conversion of Mixed Waste Food Substrates by Carotenogenic Yeasts of sp. Genus.

The consequence of the massive increase in population in recent years is the enormous production of mainly industrial waste. The effort to minimize these waste products is, therefore, no longer sufficient. Biotechnologists, therefore, started looking for ways to not only reuse these waste products, but also to valorise them.

Production of Enriched Biomass by Carotenogenic Yeasts Cultivated on by-Products of Poultry Processing-A Screening Study.

Carotenogenic yeasts are a group of microorganisms producing valuable metabolites such as carotenoids, ergosterol, ubiquinone or fatty acids. Their exceptional adaptability allows them to grow in diverse conditions. Owing to their extracellular lipase activity, they are capable of processing many lipid-type waste substrates.

Production of Enriched sp. Yeast Biomass Cultivated on Mixed Coffee Hydrolyzate and Fat/Oil Waste Materials.

One of the most addressed topics today is the transfer from a linear model of economics to a model of circular economics. It is a discipline that seeks to eliminate waste produced by various industries. The food industry generates huge amounts of waste worldwide, particularly the coffee industry, and related industries produce millions of tons of waste a year.

Bioreactor Co-Cultivation of High Lipid and Carotenoid Producing Yeast and Several Microalgae under Stress.

The co-cultivation of red yeasts and microalgae works with the idea of the natural transport of gases. The microalgae produce oxygen, which stimulates yeast growth, while CO produced by yeast is beneficial for algae growth. Both microorganisms can then produce lipids.

Revealing the Potential of Lipid and β-Glucans Coproduction in Yeast.

Beta (β)-glucans are polysaccharides composed of D-glucose monomers. Nowadays, β-glucans are gaining attention due to their attractive immunomodulatory biological activities, which can be utilized in pharmaceutical or food supplementation industries. Some carotenogenic yeasts, previously explored for lipid and carotenoid coproduction, could potentially coproduce a significant amount of β-glucans.

Explaining the decline in coronary heart disease mortality in the Czech Republic between 1985 and 2007.

Background: Coronary heart disease (CHD) mortality has declined substantially in the Czech Republic over the last two decades.

Design: The purpose of this study was to determine what proportion of this CHD mortality decline could be associated with temporal trends in major CHD risk factors and what proportion with advances in medical and surgical treatments.

Methods: The validated IMPACT mortality model was used to combine and analyse data on uptake and effectiveness of CHD management and risk factor trends in the Czech Republic in adults aged 25-74 years between 1985 and 2007.

[Tuberculosis cases in the Czech Republic in 2009].

Background: The number of notified tuberculosis cases in the Czech Republic in 2009 was lower than in 2008. 710 new tuberculosis cases and relapses were reported.

Material And Methods: 598 cases were pulmonary tuberculosis and from them 439 were proved pulmonary tuberculosis cases.

Longitudinal trends in cardiovascular mortality and blood pressure levels, prevalence, awareness, treatment, and control of hypertension in the Czech population from 1985 to 2007/2008.

Objectives: To assess longitudinal trends in cardiovascular mortality and population mean blood pressure, prevalence, awareness, treatment, and control of hypertension in a representative Czech population sample from 1985 to 2007/2008.

Methods: Source data on mortality rates were provided by the Czech Statistical Office and further processed by the Institute for Health Information and Statistics of the Czech Republic. Six independent cross-sectional population surveys were conducted in 1985, 1988, 1992, 1997/1998, 2000/2001, and 2007/2008 with randomly selected men and women aged 25-64 years and resident in six districts of the Czech Republic (Praha-východ, Benešov, Pardubice, Chrudim, Cheb, and Jindřichův Hradec).

Cardiovascular surveys: manual of operations.

Cardiovascular disease (CVD) is the leading cause of death and hospitalization in both men and women in nearly all countries of Europe. The most frequent forms of CVD are those of an atherosclerotic origin, mainly ischaemic heart disease, stroke and heart failure. The magnitude of the problem contrasts with the usual paucity and poor quality of data available on incidence and prevalence of CVD, except for few rigorous but limited studies.
