اکسیداسیون لیپیدها در طول نگهداری مواد خام، عمل آوری غذاها و نیز تیمارهای حرارتی اتفاق می افتد. این وضعیت در مواقعی که انبارداری در دوره پایانی محصول باشد بیشتر رخ می دهد که معمولاً منجر به از بین رفتن طعم و آروما در محصول خواهد شد. در این مطالعه، ابتدا کل ترکیبات فنولیک رزماری پس از استخراج با اتانول 80% تعیین شد و سپس عصاره با غلظت های مختلف از ترکیبات فنولیک در دو مدل سیستم برای اثبات رابطه ت...
-Atherosclerosis is characterized by infiltration in the lesions of cytokine-producing T cells and macrophages, where oxidized LDL may play an important role. However, little is known about the role of the immune system in the development of hypertension. Lysophosphatidylcholine (LPC) is formed by phospholipase A(2)-induced hydrolysis and/or by oxidation of LDL and other phospholipid-containing...
The stability of formulated carotenoid diets during feed processing and under different storage conditions were studied. All carotenoid diets were split into two groups with one group containing BHT (acting as an antioxidant) at 250 ppm and the other without BHT. The experiment was divided into two parts. First, all diets were evaluated in total carotenoid (TC) loss during feed processing, in d...
C. Muscalu, J. Pipher, T. Tao and C. Thiele proved in [27] that the standard bilinear and bi-parameter Hilbert transform does not satisfy any L estimates. They also raised a question asking if a bilinear and bi-parameter multiplier operator defined by Tm(f1, f2)(x) := ∫ R m(ξ, η)f̂1(ξ1, η1)f̂2(ξ2, η2)e 1122dξdη satisfies any L estimates, where the symbol m satisfies |∂ ξ ∂ ηm(ξ, η)| . 1 dist(ξ,Γ1...
The breath hydrogen test (BHT) was adapted for use in young infants and children. The diagnostic criterion of sugar malabsorption in the BHT was determined by oral administration of 0.5 g/kg of unabsorbable sugar (lactulose) to 21 healthy infants and children. A maximum increase in breath hydrogen less than 0.05 ml/min per m2 was observed in all subjects. A good correlation between results by t...
The forkhead box (Fox) proteins are a growing family of transcription factors that have important roles in cellular proliferation and differentiation and in organ morphogenesis. The Fox family members hepatocyte nuclear factor (HNF)-3beta (Foxa2) and HNF-3/forkhead homolog (HFH)-8 (FREAC-1, Foxf1) are expressed in adult pulmonary epithelial and mesenchymal cells, respectively, but these cells d...
Studies on natural compounds are of interest in now a day, due to their satisfactory health benefits with low toxicity. Herbs and spices have been added to different types of food to impart flavour as well as to improve storage stability due to their anti-oxidant effects. Anti-oxidants play a major role in curing degenerative diseases. In current scenario many synthetic antioxidants are commonl...
Carbon tetrachloride (CCl4), a hepatotoxic agent is widely used to study the toxic mechanisms in experimental animals. This study was carried out to establish the hepatoprotective measures of food preservative antioxidants butylated hydroxyanisole and butylated hydroxytolune (BHA, BHT) when mixed with food towards carbon tetrachloride (CCl4) intoxication (230 mg/ kg b wt/rat/day) in rat. Bioche...
The eciency of various commercial hindered phenol antioxidants was studied using dierential scanning calorimetry (DSC) to determine the oxidation induction time (OIT) of antioxidant solutions in squalane. It was observed that a-tocopherol has an exceptionally high antioxidant activity. In fact, after normalisation for the molecular weight and functionality of each antioxidant, a-tocopherol wa...
Superconductivity is a fascinating quantum phenomenon characterized by zero electrical resistance and the Meissner effect. To date, several distinct families of superconductors (SCs) have been discovered. These include three-dimensional (3D) bulk SCs in both inorganic and organic materials as well as two-dimensional (2D) thin film SCs but only in inorganic materials. Here we predict superconduc...
