the aim of this research was to investigate the efficiency of ldpe films incorporating fifferent nanofillers in extending orange juice shelf life. fresh orange juice packed in different films was assessed for microbial stability, ascorbic acid content, ph, color parameters and sensory quality during 0, 7, 28 and 58 d of storage. mold and yeast growth, acidophil and aerobic mesophil bacteria pop...

background: selective phosphodiesterase (pde3) inhibitors improve cardiac contractility and may use in congestive heart failure. however, their proarrhythmic potential is the most important side effect. methods: in this research, we evaluated the potential cardiotonic activity of six new synthesized selective pde3 inhibitors (6-hydroxy-4-methylquinolin-2(1h)-one derivatives) using the spontaneo...

hie-124 is a new member of ultra-short acting hypnotics’ drug family. in this research, the synthesis ofanalogues of hie-124 drug in the heterocyclic thiazole ring replaced to thiadiazole, will be presented.thiadiazolodiazepines during a two-step reaction starting from the amino thiadiazole resultedfrom-various derivatives of benzoic acid and thiosemicarbazide were synthesized. in the first ste...

sexual behavior in most moths is limited to a precise duration period of either the day or the night. these behaviors as well as the calling behavior are specific. information on reproductive behavior is important in the chemical ecology studies. experiments were conducted to determine the developmental biology, adult time emergence and calling behaviors of three populations of carob moth, ecto...

inflammation can lead to malabsorption of important micronutrients such as iron. malabsorption and nutritional deficiency can be caused by a variety of pathological and environmental factors causing a range of other symptoms commonly caused by both h. pylori infection and coeliac disease (cd). national guidelines suggest the routine taking of duodenal biopsies to exclude cd when investigating p...

climate change impacts on precipitation and temperature world-wide are not yet well understood (especially for precipitation), due to their complexity and regional variability. in this study in order to explicit the impact of climate change on precipitation and temperature in iran, 15 aogcm whose greenhouse gases scenarios ran under a2, a1b and b1 were used. monthly precipitation and temperatur...

results aβ (1-42) stimulated the production of the proinflammatory cytokines il6, il1β, tnfα, and il18 in both the primary microglia cell culture and the b92 cell line. both the raav-il4 construct and the ril-4 protein were found to inhibit production of the most important aβ (1-42)-induced proinflammatory cytokine mrnas in the two types of cells with different patterns. conclusions it seems th...

some 2-iminothiazolidin-4-ones have been synthesized by the reaction of dialkyl acetylenedicarboxylates with thiosemicarbazones. the reaction was performed in the presence of 10 mol% of triphenylphosphine and tetrabutylammonium bromide as a phase transfer catalyst in water as a green solvent. all the synthesized compounds were characterized by their physical and spectral data.
