Application of seaweeds to develop new food products with enhanced shelf-life, quality and health-related beneficial properties
2017
International audience; Edible seaweeds are a good source of antioxidants, dietary fibers, essential amino acids, vitamins, phytochemicals, polyunsaturated fatty acids, and minerals. Many studies have evaluated the gelling, thickening and therapeutic properties of seaweeds when they are used individually. This review gives an overview on the nutritional, textural, sensorial, and health-related properties of food products enriched with seaweeds and seaweed extracts. The effect of seaweed incorporation on properties of meat, fish, bakery, and other food products were highlighted in depth. Moreover, the positive effects of foods enriched with seaweeds and seaweed extracts on different lifestyl…
Monounsaturated fatly acid metabolism and colon cancer cells proliferation : role of Stearoyl-CoA desaturase-1 and effect of conjugated linoleic acid…
2012
Cancer cells adapt their metabolism in response to signals from the microenvironment and proliferation. Thus, MonoUnsaturated Fatty Acid (MUFA) synthesis is increased in colon cancer cells, and associated with increased Stearoyl-CoA Desaturase (SCD) activity, the rate limiting enzyme of MUFA biosynthesis. Polyunsaturated Fatty Acid (PUFA), as isomers of conjugated linoleic acid (CLA), exert inhibitor activity on SCD-1 and have anti-cancer properties, but their mechanisms are not yet clear. In this context, the aim of this work was first to evaluate the role of SCD-1 in the proliferation of colon cancer cells (CCC) and to define the underlying mechanisms. In a second time, we provide new inf…
Cellular metabolic alteration : the voice of monoinsaturated fatty acid as therapeutic target
2010
Stearoyl Co-A desaturase (SCD) is the key enzyme of the metabolism of mono-unsaturated fatty acids (MUFA). Its activity 9 desaturase introduces a double bond cis in position 9 of saturated fatty acids (SFA), induced formation of MUFA. Impaired biosynthesis of MUFA is involved in many diseases such as cancer and cardiovascular disease. Cancer cells have a de novo synthesis of fatty acids increased with an accumulation MUFA. This change in the metabolism of fatty acids is associated with overexpression SCD1 which catalyzes the conversion of saturated fatty acids, monounsaturated fat. Several reports have shown that inhibition of SCD1 leads to blockage of proliferation and induction of apopt…
Plasmalogen metabolism in retinal glial cells : interaction between cells during normal or pathological vascular development
2017
Retinal vascular disorders such as retinopathy of prematurity (ROP), diabetic retinopathy or age-related macular degeneration represent the first cause of vision loss at all ages in industrialized countries. Many epidemiological or animal studies have shown the involvement of polyunsaturated fatty acids (PUFA) in the regulation of vascular development and more specifically the beneficial properties of omega 3 PUFA (n-3 PUFA) against pathological vascularization. Those PUFA are esterified on glycerophospholipids (GP). GP are the primary constituents of the lipid bilayer of cell membranes. PUFA can be also esterified on a specific class of GP, called plasmalogens. Plasmalogens are characteriz…
RISCHI E VIRTU’ DEL CONSUMO DI PESCE CRUDO
2013
Il consumo di pesce crudo in questo ultimo ventennio è notevolmente aumentato, ciò è dovuto non solo alle benefiche caratteristiche alimentari del pesce ma soprattutto alla moda di cui il consumatore è fortemente influenzato. Il pesce è una preziosa fonte di proteine, minerali e vitamine di alta qualità.
Ventilatory chemosensitivity, cerebral and muscle oxygenation, and total hemoglobin mass before and after a 72-day mt. Everest expedition.

Abstract. Cheung, Stephen S, Niina E. Mutanen, Heikki M. Karinen, Anne S. Koponen, Heikki Kyro ̈ la ̈ inen, Heikki O. Tikkanen, and Juha E. Peltonen. Ventilatory chemosensitivity, cerebral and muscle oxygenation, and total hemoglobin mass before and after a 72-day Mt. Everest expedition. High Alt Med Biol 15:331–340, 2014.— Background: We investigated the effects of chronic hypobaric hypoxic acclimatization, performed over the course of a 72-day self-supported Everest expedition, on ventilatory chemosensitivity, arterial saturation, and tissue oxygenation adaptation along with total hemoglobin mass (tHb-mass) in nine experienced climbers (age 37 – 6 years, _ VO 2peak 55 – 7mL $ kg - 1 $ min…
Using natural analogues to investigate the effects of climate change and ocean acidification on Northern ecosystems
2018
AbstractNorthern oceans are in a state of rapid transition. Still, our knowledge of the likely effects of climate change and ocean acidification on key species in the food web, functionally important habitats and the structure of Arctic and sub-Arctic ecosystems is limited and based mainly on short-term laboratory studies on single species. This review discusses how tropical and temperate natural analogues of carbonate chemistry drivers, such as CO2 vents, have been used to further our knowledge of the sensitivity of biological systems to predicted climate change, and thus assess the capacity of different species to show long-term acclimation and adaptation to elevated levels of pCO2.

Uz lietotāja modeli balstīta personalizēta adaptīva e-studiju sistēma
2017
Promocijas darbs ir veltīts uz lietotāja modeli balstītas personalizētas adaptīvas e-studiju sistēmas izveides metožu izstrādei, lai veicinātu un uzlabotu e-studiju izmantošanu apmācības procesā. Darbā apskatīti adaptīvajās sistēmās iekļaujamie pamatmodeļi, īpašu uzmanību veltot lietotāja modelim un eksistējošajām adaptācijas metodēm. Balstoties uz esošo risinājumu analīzi, ir izstrādāts uz datu dzīves ilgumu bāzēts lietotāja modelis un piedāvātas trīs jaunas adaptācijā izmantojamās metodes: apmācāmo grupu veidošanas metode, kursa optimālās tēmu secības izveides metode un tēmu secības organizēšanas metode. Izstrādātais lietotāja modelis un adaptācijas metodes nodrošina iespēju katram sistēm…
