The objective of this study was to determine the effect of bovine follicular fluid proteins (bFF) and their differently charged groups as maturation media supplements for in vitro embryo development. bFF was obtained by aspiration from large healthy follicles (4-10 mm in diameter) and was precipitated by 30-50% (NH4)2SO4. The precipitated protein was fractionated into basic and acidic fractions...
The electrochemical oxidation behavior of m-nitrophenol (m-NP) was studied comparatively on glassy carbon electrode, Pt electrode, PbO2 electrode, SnO2 electrode, and graphite electrode using cyclic voltammetry. The cyclic voltammetry measurements were performed in acidic (1 M H2SO4, pH 0.4), neutral (1 M Na2SO4, pH 6.8), and...
Electrooxidation of methanol was realised on platinum and perchlorate anion doped polypyrrole film electrodes in acidic media. A systematic kinetic investigation was performed and optimum experimental conditions for the preparation of the electrocatalytic system were determined. The presence of ClO4 − anions was confirmed by XPS analysis of the doped polymer matrix. © 2001 Elsevier Science B.V....
Background: Today factors including cultural, social, religious, economic and medical such as X Linked diseases encouraged couples to choose traditional methods or new treatment for selecting the gender of child. It seems that Spermatozoa containing chromosomes X and Y have different speed in various pH. In this study the velocity of spermatozoa in different acidic pH was evaluated. Materials a...
با توجه به شیوع سرطان در جوامع امروزی، یافتن داروهای جدید برای درمان آن از اهمیت بالایی برخوردار است. استفاده از داروهای شیمیایی موجود به دلیل عوارض جانبی که دارند با محدودیت مصرف روبه رو می باشند. از این رو محققین درصدد یافتن مواد طبیعی با خاصیت ضد سرطانی می باشند. هدف اصلی این پایان نامه بررسی اثرات ضد سرطانی lactoferrin وwhey acidic protein موجود در شیر شتر می باشد. در تحقیق حاضر تأثیر lacto...
