سابقه و هدف: پوست سبز گردو از ضایعات کشاورزی است که به دلیل داشتن ترکیبات فنولی، میتواند به عنوان ترکیبات طبیعی با خواص بیولوژیک مطرح باشد. این تحقیق با هدف استخراج عصاره آبی پوست سبز و بررسی اثر دمای استخراج بر میزان ترکیبات فنولی و فعالیت آنتی اکسیدانی و ضدمیکروبی، همچنین اثر فرآیند ریزپوشانی کردن عصاره استخراجی به روش خشککن پاششی در مالتودکسترین بر فعالیت بیولوژیک عصاره بررسی گردید. مواد ...
Purpose: To investigate the effects of oligosaccharides on the functional properties of wheat starch. Methods: The blue value, retrogradation and pasting properties of wheat starch were determined. In addition, water activity (Aw), melting enthalpy and melting temperature of wheat starch paste were analyzed. Results: Fructo-oligosaccharide (FOS) and xylo-oligosaccharide (XOS) inhibited the retr...
Plethysmographic specific airway resistance (sR(aw)) is a useful research method for discriminating lung disease in young children. Its use in clinical management has, however, been limited by lack of consensus regarding equipment, methodology and reference data. The aim of our study was to collate reference data from healthy children (3-10 yrs), document methodological differences, explore the...
This study examined the relationship between airway blood flow (Q(aw)), ventilation (V(E)) and cardiac output (Q(tot)) during exercise in healthy humans (n=12, mean age 34+/-11 yr). Q(aw) was estimated from the uptake of the soluble gas dimethyl ether while V(E) and Q(tot) were measured using open circuit spirometry. Measurements were made prior to and during exercise at 34+/-5 W (Load 1) and 6...
[1] Interaction of warm, Atlantic-origin water (AW) and colder, polar origin water (PW) advecting southward in the East Greenland Current (EGC) influences the heat content of water entering Greenland’s outlet glacial fjords. Here we use depth and temperature data derived from deep-diving seals to map out water mass variability across the continental shelf and to augment existing bathymetric pro...
Abstract. Potassium feldspars (K-feldspars), such as microcline, are considered key dust minerals inciting ice nucleation in mixed-phase clouds. Besides the high activity of recent studies also revealed a sensitivity microcline to interaction with solutes on its surface. Here, we investigate effect organic and bio-organic substances aim better understand underlying surface interactions. We perf...
Food-borne outbreaks associated with low water activity (aw) foods involve Salmonella contamination, and its control is a significant challenge. In India, milk (doodh) peda aw traditional popular food. Accordingly, it essential to determine the prevalence survival of spp. in artificially spiked stored for an extended period at different aw. was not detected any 25 indigenous samples. did grow H...
زمینه و هدف: به علت افزایش روزافزون مقاومت آنتی بیوتیکی، شناسایی خواص ضدمیکروبی گیاهان دارویی از اهمیت ویژه ای برخوردار است. مطالعه حاضر با هدف ارزیابی فعالیت ضدمیکروبی عصاره های گیاهان رازک معمولی و بلوط (گونه بُلَند مازو) علیه چند سویه استاندارد میکروبی انجام گردید. مواد و روش ها: در این مطالعه تجربی، عصاره های الکلی و آبی گیاهان رازک و بلوط استخراج شدند. اثرات بازدارندگی عصاره های گیاهی علیه س...
