سدیم آلژینات (alg ) یک نوع پلیمر طبیعی غیر سمی ، همچنین زیست سازگار و تخریب پذیر میباشد. پلی وینیل الکل (pva ) نیز از پلیمر های سنتزی و زیست سازگار است که خواص مکانیکی قابل توجهی دارد به همین دلیل از pva و alg در مهندس بافت و ساخت داربست های زیست تخریب پذیر استفاده ی فراوانی می شود. از طرفی ژلاتین (gel) یکی از زیر شاخه های کلاژن می باشد که سهم عمده ای در ساختار شبکه خارج سلولی دارد و می تواند ...

The effects of some pretreatments including blue-green and green algae and minerals on the induction of me-tabolic and biochemical process of germination were studied in Dracocephalum kotschyi Boiss. seeds. The seeds were pretreated with green algae Spirulina platensis, Chlorella vulgaris and Dunaliella bardawil or D. IR-1 (Isolated from Gave-Khooni-salt marsh) and modified Johnson nutrient med...

Image Processing is having is significance for disease detection on medical images. These disease recognition and classification approaches are specific to human organ and image type. One of such disease class includes detection of retinal disease such as glaucoma detection or diabetic detection. The paper has defined a study on disease recognition approaches such as SVM, DCT, HMM and PCA appro...

Results of renal function tests done on 36 patients on prophylactic lithium treatment are compared with those of 28 age matched individuals, also being treated for affective disorders but exposed only to neuroleptics and/or tricyclic antidepressants. 25% of the lithium treated patients had A.D.H. resistant concentration dysfunction resulting in polyuria and polydypsia. Serum lithium levels had ...

Transport phenomenon across membranes are very important as they work as guiding principles for drug permeation studies across biological membranes. Classical thermodynamics is confined to the systems of equilibrium i.e. to reversible processes only and cannot be applied to the irreversible systems where variables defining the systems are changing with time and situation. The utility of irrever...

Molten salt hydrates (MSHs) are remarkable in breaking through the recalcitrant structure of microcrystalline cellulose and raw biomass. After being pretreated 60 wt% LiBr at 130 °C for 2 h, crystallinity as well degree polymerization (DP) decreased. It was found that 91.3% yield removed from MSHs by filteration followed hydrolyzed into glucose with a high 75.3% dilute acid under mild reaction ...
